Description

Technical Field

[0001] This utility model belongs to the field of automotive seats, specifically relating to a seat handle fixing structure and a seat. Background Technology

[0002] In the automotive manufacturing industry, seats are an important component, and their ease of operation and rational spatial layout have a decisive impact on the driving and riding experience.

[0003] Currently, most car seat handles on the market are fixed with bolts. Therefore, during the car seat production and assembly process, workers need to use specialized tools to tighten each bolt individually to ensure the handle is securely installed. Moreover, the entire car seat assembly process is cumbersome and time-consuming, significantly reducing overall assembly efficiency. Furthermore, when repairing or replacing the seat handles later, workers also need to use tools to disassemble them, increasing the difficulty and cost of subsequent repairs. Especially with frequent disassembly and installation, this can cause bolt stripping or damage to seat components, further increasing repair costs. In addition, bolt-fixed structures often require a large installation space on the seat, not only occupying the already limited space inside the vehicle, affecting the compactness and aesthetics of the seat layout, but also limiting the flexibility of seat design to some extent.

[0004] With the rapid development of the automotive industry, consumers have increasingly higher demands for vehicle quality and user experience. Some car seat handles have begun to adopt a snap-on installation structure to simplify installation and reduce the space occupied by the overall structure. However, when disassembling a car seat, the snap-on installation structure often still requires tools to apply pressure or tension to a portion of the snap-on structure to separate the relevant components. Therefore, the existing seat handle fixing structure not only demands a high level of technical skill and experience from repair personnel, but is also prone to deformation or breakage of the snaps due to improper force application, or scratches and damage to surrounding components. Utility Model Content

[0005] The purpose of this utility model is to address the problems of high operational requirements and easy damage in practical applications of existing seat handle fixing structures, and to propose and design a seat handle fixing structure and seat that can overcome the above problems. While achieving the functions of fixing the seat handle and preventing it from falling off, it has the advantages of simple structure, low operational requirements, not easy to damage, and easy disassembly.

[0006] To achieve the above objectives, on the one hand, this utility model provides a seat handle fixing structure, which includes a seat handle and a pin. The inner side of the seat handle is provided with a connector. One end of the pin can be installed on the seat body, and the other end of the pin is fitted with a connecting sleeve, which is inserted into the connector. Two auxiliary opening slots are symmetrically opened on the wall of the connecting sleeve at the end away from the seat handle. The opening direction of the auxiliary opening slots is towards the direction away from the seat handle. A first buckle is provided on both sides of the auxiliary opening slot, and the first buckle is located on the outer wall of the connecting sleeve. The wall of the connector is provided with two first openings, and the two first openings are engaged with the corresponding first buckles. At this point, because this utility model not only connects the connecting sleeve and the seat handle using a snap-fit ​​structure, but also provides an auxiliary opening groove at the snap-fit ​​structure, it not only features convenient installation, simple operation, and no need for tools during the installation of the seat handle, but also features convenient installation, simple operation, and no need for tools during the disassembly of the seat handle. In other words, during the disassembly of the seat handle, the operator can directly press the auxiliary opening groove manually to separate the first snap from the corresponding first opening, thereby achieving the purpose of quick disassembly without the need for tools such as pry bars, thus simplifying the entire disassembly process, reducing the technical level requirements for workers, and avoiding damage to components caused by the use of tools.

[0007] Furthermore, a first transition slope is provided on the end of the first buckle facing the seat handle, and the first transition slope ensures that the first buckle can slide smoothly relative to the insertion tube.

[0008] Furthermore, a first abutting flange is provided at the end of the connecting sleeve away from the seat handle. The first abutting flange abuts against the end of the insertion tube and constrains the insertion depth of the connecting sleeve in the insertion tube.

[0009] Furthermore, the insertion tube is a first rectangular tube, and the tube walls of the first rectangular tube are arranged in a clockwise direction as first tube wall, second tube wall, third tube wall, and fourth tube wall, and both the first tube wall and the third tube wall are provided with first openings; the connecting sleeve is a second rectangular tube, and the tube walls of the second rectangular tube are arranged in a clockwise direction as first tube wall, second tube wall, third tube wall, and fourth tube wall, and both the first tube wall and the third tube wall are provided with auxiliary opening slots. Moreover, the first tube wall and the third tube wall are respectively arranged opposite to the first tube wall and the third tube wall, and the second tube wall and the fourth tube wall are respectively arranged opposite to the second tube wall and the fourth tube wall, thereby ensuring that the first buckles on both sides can cooperate with the corresponding first openings and form corresponding buckle structures.

[0010] Furthermore, a first boss is provided on the outer side of the second cylinder wall and the outer side of the fourth cylinder wall, and a first groove is provided on the inner side of the second pipe wall and the inner side of the fourth pipe wall. The first boss and the corresponding first groove are slidably connected, and provide precise guidance for the relative movement of the connecting sleeve and the insertion pipe, ensuring that the connecting sleeve and the seat handle can be accurately connected together and form a corresponding snap-fit ​​structure. At the same time, the present invention can further ensure that the connecting sleeve can rotate with the seat handle through the mortise and tenon joint structure formed by the first groove and the first boss.

[0011] Furthermore, two second snaps are symmetrically arranged on the end of the pin that is used to insert into the connecting sleeve. The second and fourth cylinder walls of the connecting sleeve are each provided with a second opening. The second opening engages with the corresponding second snap to form a corresponding snap structure, so as to realize the quick installation of the pin and the connecting sleeve.

[0012] Furthermore, the first, second, third, and fourth cylindrical walls of the connecting sleeve are all provided with a third groove, and the end of the pin is provided with a cuboid portion. The four sides of the cuboid portion are slidably connected to the third grooves provided in the first, second, third, and fourth cylindrical walls, respectively, providing precise guidance for the relative movement of the connecting sleeve and the pin, ensuring that the connecting sleeve and the pin can be accurately connected together and form a corresponding snap-fit ​​structure. At the same time, this utility model can also further ensure that the pin can rotate with the connecting sleeve through the mortise and tenon joint structure formed by the third groove and the end of the pin.

[0013] Furthermore, a second transition slope is provided on the end of the second buckle facing the seat handle, and the second transition slope ensures that the second buckle can slide smoothly relative to the connecting sleeve.

[0014] Furthermore, a second abutment flange is provided at one end of the pin for insertion into the connecting sleeve. The second abutment flange abuts against the end of the connecting sleeve and constrains the insertion depth of the connecting sleeve and the pin.

[0015] On the other hand, this utility model also provides a seat, which includes a seat body and the seat body is provided with the above-mentioned seat handle fixing structure.

[0016] As can be seen from the above technical solution, this utility model has the following advantages: it is not only easy to install and simple to operate without the need for tools during the installation of the seat handle, but also easy to install and simple to operate without the need for tools during the disassembly of the seat handle. Specifically, during the disassembly of the seat handle, the operator can directly press the auxiliary opening groove manually to separate the first buckle from the corresponding first opening, thereby achieving the purpose of quick disassembly without the need for tools such as pry bars, thus simplifying the entire disassembly process, reducing the technical level requirements of the workers, and avoiding damage to parts caused by the use of tools.
