car interior handle components

Abstract: The assembly of the inner handle assembly in a car involves inserting the mandrel into the three
parts with four holes respectively, namely the handle frame, the inner handle body and the locking button.
Due to the single-sided clearance between each component being only 0.03 millimeters, the assembly
accuracy requirement is extremely high and the assembly difficulty is great. The traditional assembly method
requires two people to collaborate: one person is responsible for installing the inner handle body, locking
button, and rotating arm into the cavity groove of the inner handle frame and pressing them tightly, so
that the three pieces and four holes are accurately aligned; The other person is responsible for inserting the
core shaft to ensure assembly requirements. However, this method is inefficient and the assembly quality is
unstable. In order to solve this problem, this paper designs a semi-automatic assembly fixture for inner handle
components. This device uses a dual piston mechanism to push the pressure block to complete the clamping
action of the inner handle and locking button, and achieves the assembly action of the core shaft through a
single cylinder mechanism. During the assembly process, the operator only needs to place the inner handle
body and locking button into the handle frame, install the core shaft, and then start the single and double
cylinders to complete the assembly. This semi-automatic assembly method of the inner handle component
using pneumatic equipment not only reduces labor costs, but also significantly improves assembly efficiency
and quality.
Key words: internal handle component; internal handle body; handle frame; lock button; mandrel

投资超 3 亿，中国轮胎海外项目 +2
Investment exceeds 300 million yuan, with 2 overseas projects of Chinese tires
2025 年 5 月 7 日，据柬埔寨媒体《金边邮报》报道，2025 年前 4 个月，柬埔寨发展理事会累计批准 231 个
投资项目，总投资额达 34 亿美元。
其中，4 月份批准 59 个投资项目，总投资额 8.6 亿美元。在这些重点项目中，包括两个轮胎项目 ：位于西哈
努克省投资 2.42 亿美元的轮胎制造厂，以及位于柴桢省投资 9 300 万美元的轮胎厂。
实际上，近年来中国轮胎企业纷纷在柬埔寨布局设厂，轮胎制造业已成为柬埔寨最大的外来直接投资来源。
目前，柬埔寨已吸引 6 家中国轮胎制造企业设立生产基地，其中已有 3 家轮胎厂投入运营，分别是位于柴桢
省巴域市的赛轮轮胎、西哈努克省的通用轮胎，以及桔井省的双星轮胎厂。
2025 年 1 月，万力轮胎柬埔寨生产基地举行奠基仪式，该项目位于柴桢省新巴域特区，分为两期建设，一
期投资约 2.39 亿美元，总占地面积约 32 公顷。而福麦斯轮胎也在柬埔寨积极布局，工厂预计于 2025 年 5 月正
式投产。此外，柬埔寨发展理事会去年批准正道轮胎投资项目，预计年产 600 万套半钢子午线轮胎及 120 万套全
钢子午线轮胎。
柬埔寨橡胶资源丰富，同时，政府提供优惠的投资政策，加上柬埔寨与中国的紧密友好关系，以及美国未对
柬埔寨轮胎征收反倾销税，这些因素吸引众多中国轮胎制造商在柬埔寨设厂。
据柬埔寨政府估计，一旦这些轮胎厂全部投产，将极大推动柬埔寨橡胶加工行业的发展。
