Description

Technical Field

[0001] This utility model relates to the field of thrust cap assembly, specifically an assembly mechanism that can prevent incorrect or missing thrust caps from being installed on seats. Background Technology

[0002] Typically, the thrust cap and synchronizing rod are installed manually using a thrust cap auxiliary tool. However, this manual assembly process lacks a detection device to prevent errors and omissions in the thrust cap. The manual assembly process cannot prevent problems such as missing or incorrect installation of the thrust cap, jamming, or abnormal noises due to movement. Furthermore, the pressing distance of the thrust cap is affected by the force applied by the employee, resulting in fluctuations.

[0003] Therefore, we propose an assembly mechanism to prevent incorrect or missing seat thrust caps, thus solving the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an assembly mechanism that can prevent incorrect or missing installation of seat anti-stress caps.

[0005] This utility model provides an assembly mechanism to prevent incorrect or missing installation of seat thrust caps. It includes a slide base plate, a fixing plate fixed to one end of the slide base plate, a cylinder fixed to one side of the fixing plate, a connecting plate assembly mounted on the output end of the cylinder, a connecting rod mounted on the connecting plate assembly, and a pre-installed contouring rod fixedly connected to the end of the connecting rod away from the connecting plate assembly via a pin. If the thrust cap is installed backwards, it will not be able to be fastened onto the pre-installed contouring rod and will fall off directly; if the thrust cap is used incorrectly / incorrectly installed, it will also be unable to fit onto the contouring head. The pre-installed contouring rod is fixed to the connecting rod via a pin, allowing for quick disassembly and reconfiguration. The end of the pre-installed contouring rod has an installation groove for embedding a synchronization rod. A thrust cap compression depth control assembly is installed in the installation groove. A limit block is fixed to the end of the slide base plate away from the fixing plate, and a bracket is mounted on one side of the limit block. A position sensor is mounted on the top of the bracket to detect whether a thrust cap is missing. If the position sensor cannot detect the presence of the thrust cap, the assembly cannot proceed to the next step.

[0006] When the cylinder is inflated, it will cause the entire pre-assembly mechanism to slide to the right. With the help of the positioning block, the thrust cap can be inserted into the synchronizing rod. When the cylinder is deflated, it will cause the entire pre-assembly mechanism to slide to the left, causing the mechanism to disengage.

[0007] Preferably, the thrust cap extrusion depth control assembly includes a cylindrical insert, a circular washer, and a screw. The conformal pre-installed rod has a threaded hole inside, and the threaded hole communicates with the mounting groove. The cylindrical insert has a mounting hole inside, and the screw passes through the mounting hole. The circular washer and the threaded hole are connected by threads.

[0008] During the push-fitting of the thrust cap, there is a relative movement between the thrust cap and the synchronizing rod. The distance between the thrust cap and the adjusting device is a critical functional factor. If the distance is too small, it will cause frictional noise; if the distance is too large, it will cause surging and also cause noise. Therefore, the depth of the mounting groove for the synchronizing rod to be inserted into the pre-fitting rod head is designed to be adjustable. When the depth of the mounting groove needs to be adjusted, simply insert a circular shim under the cylindrical insert to decrease the pressing depth of the thrust cap; conversely, to increase the pressing depth, the pressing depth can be increased. This allows the pressing depth of the thrust cap to depend on both the cylinder stroke and the limit block, as well as the depth of the pre-fitting rod head.

[0009] Preferably, the side wall of the pre-fitting rod is provided with a notch for avoiding the pre-fitting rod, and a notch is opened at the bottom of the pre-fitting rod and the connecting rod to prevent the pre-fitting rod and the connecting rod from hitting the position sensor of the thrust cap during the process of the cylinder pushing the thrust cap.

[0010] Preferably, one end of the conformal pre-installed rod is provided with a groove, and one end of the connecting rod is provided with a protrusion. The protrusion cooperates with the groove to facilitate the positioning of the positioning hole.

[0011] Preferably, both the connecting rod and the pre-assembled rod are provided with positioning holes that cooperate with the pins, which facilitates disassembly and assembly.

[0012] Preferably, the connecting plate assembly includes a horizontal plate and an L-shaped mounting base fixed to the top of the horizontal plate. The connecting rod is fixedly connected to the L-shaped mounting base. The horizontal plate is provided with a T-shaped groove, and the piston rod end of the cylinder is installed in the T-shaped groove, which facilitates the assembly and disassembly of the horizontal plate and the cylinder.

[0013] Preferably, a slider is fixed to the bottom of the horizontal plate, and the slider is slidably connected to the slide base plate to make the horizontal plate move more smoothly.

[0014] Compared with related technologies, the present invention provides the following beneficial effects:

[0015] Improve assembly accuracy:

[0016] The design of the pre-fitting rod ensures that the thrust cap can be installed accurately and without error in the designated position. If the thrust cap is installed backwards or incorrectly, it will not be able to fit smoothly into the pre-fitting rod, thus effectively avoiding the problems of incorrect installation and omission.

[0017] The placement of position sensors further enhances assembly accuracy. If the sensors fail to detect the presence of the thrust cap, the entire assembly process cannot proceed to the next step, thus ensuring that each seat is fitted with the correct thrust cap.

[0018] Enhance assembly flexibility:

[0019] The pre-assembled rod and connecting rod are connected by a pin, enabling quick disassembly and replacement. This design allows the assembly mechanism to quickly adapt to different seat types and assembly requirements, improving assembly flexibility and efficiency.

[0020] The adjustability of the thrust cap extrusion depth control component also enhances assembly flexibility. By adjusting the number of circular shims under the cylindrical insert, the depth of the mounting slot can be easily changed, thereby precisely controlling the extrusion depth of the thrust cap.

[0021] Improve production efficiency:

[0022] The cylinder's inflation and deflation process enables rapid sliding and disengagement of the pre-assembly mechanism, significantly shortening assembly time. This automated and mechanized assembly method not only improves production efficiency but also reduces the difficulty and labor intensity of manual operation.

[0023] The T-slot design on the connecting plate assembly and the cross plate makes it easier and faster to disassemble and assemble the cylinder and connecting rod, further improving assembly efficiency.

[0024] Ensure product quality:

[0025] This assembly mechanism uses precise control and inspection methods to ensure that the thrust caps of each seat are installed in the correct position and depth. This rigorous quality control helps to improve the overall quality and durability of the seats.

[0026] At the same time, this mechanism can effectively avoid problems such as friction noise and movement that may occur during the assembly process, thereby improving the comfort and safety of the seat.

[0027] Reduce maintenance costs:

[0028] The assembly mechanism features a rational and compact structural design, making it easy to maintain and service. The connections between all components are tight and stable, reducing the failure rate caused by loosening or wear.

[0029] Furthermore, because the organization uses standardized parts and components, replacement parts can be easily found when performing repairs or replacements, reducing maintenance costs and time. Attached Figure Description

Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] Please refer to the following: Figures 1 to 4 An assembly mechanism to prevent incorrect or missing seat thrust caps is disclosed. This mechanism is primarily constructed around a slide base plate 1. A fixing plate 2 is fixedly mounted at one end of the slide base plate 1, and a cylinder 3 is firmly connected to one side of the fixing plate 2. The output end of the cylinder 3 is cleverly designed with a connecting plate assembly 4, which provides stable support and power to the entire pre-assembly mechanism.

[0037] A connecting rod 5 is carefully installed on the connecting plate assembly 4. The other end of the connecting rod 5 is securely connected to the contour pre-assembly rod 7 via a pin 6. This design not only ensures that the contour pre-assembly rod 7 can be accurately positioned and pre-installed with the thrust cap, but also allows the contour pre-assembly rod 7 to be quickly disassembled and replaced via the connection method of the pin 6 to adapt to different assembly requirements.

[0038] The end of the pre-mounted guide rod 7 features a cleverly designed mounting slot 8, specifically for embedding the synchronizing rod and pre-installing the thrust cap. If the thrust cap is installed backwards, it will not be able to latch onto the pre-mounted guide rod 7 and will fall off directly; similarly, if the thrust cap is misused or incorrectly installed, it will not be able to smoothly fit onto the guide head of the pre-mounted guide rod 7. This design effectively avoids the problems of incorrect or missing thrust cap installation.

[0039] Within the mounting slot 8, a thrust cap compression depth control assembly 9 is cleverly installed. This assembly consists of a cylindrical insert 13, a circular washer 14, and a screw 15. The contoured pre-mounted rod 7 has a threaded hole 16 communicating with the mounting slot 8, while the cylindrical insert 13 has a mounting hole 17. By passing the screw 15 through the mounting hole 17, the circular washer 14, and connecting it to the threaded hole 16, the depth of the mounting slot 8 can be easily adjusted, thereby precisely controlling the compression depth of the thrust cap.

[0040] A limit block 10 is fixedly installed at the end of the slide base plate 1 away from the fixed plate 2. A bracket 11 is installed on one side of the limit block 10. A position sensor 12 is carefully installed on the top of the bracket 11. The main function of this sensor is to detect whether the thrust cap is missing. If the position sensor 12 cannot detect the presence of the thrust cap, the entire assembly process cannot proceed to the next step, thus ensuring the accuracy and reliability of the assembly.

[0041] When cylinder 3 is inflated, it will cause the entire pre-assembly mechanism to slide to the right. Under the positioning action of limit block 10, the thrust cap can be smoothly inserted into the synchronizing rod. When cylinder 3 is deflated, it will cause the entire pre-assembly mechanism to slide to the left, allowing the mechanism to smoothly exit the working position.

[0042] Furthermore, a notch 18 is cleverly provided on the side wall of the pre-mounted guide rod 7. This notch is designed to prevent the pre-mounted guide rod 7 and connecting rod 5 from hitting the position sensor 12 of the thrust cap during the process of the cylinder 3 pushing the thrust cap. At the same time, one end of the pre-mounted guide rod 7 is provided with a groove 19, while one end of the connecting rod 5 is provided with a protrusion 20. The clever cooperation between the protrusion 20 and the groove 19 not only facilitates the positioning operation of the positioning hole 21, but also further enhances the connection stability between the connecting rod 5 and the pre-mounted guide rod 7.

[0043] The connecting plate assembly 4 also has a very ingenious structure. It consists of a horizontal plate 22 and an L-shaped mounting base 23 fixed to the top of the horizontal plate 22. The connecting rod 5 is securely connected to the L-shaped mounting base 23. A T-slot 24 is cleverly provided on the horizontal plate 22. The piston rod end of the cylinder 3 is installed in the T-slot 24. This design not only facilitates the disassembly and assembly of the horizontal plate 22 and the cylinder 3, but also ensures that the cylinder 3 can smoothly and accurately push the connecting rod 5 and the contoured pre-installed rod 7 to work.

[0044] Finally, sliders 25 are fixed to the bottom of the horizontal plate 22. These sliders 25 are slidably connected to the slide base plate 1, making the horizontal plate 22 move more smoothly and steadily. This design not only improves the working efficiency and accuracy of the entire pre-assembly mechanism, but also further enhances the stability and reliability of the mechanism.

[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
