Description

Technical Field

[0001] This utility model relates to the field of automotive parts assembly tooling technology, and in particular to an automotive air conditioning toggle assembly fixture. Background Technology

[0002] Currently, most car air conditioning knobs on the market adopt a split design, referring to... Figure 1 As shown, the car air conditioning toggle knob 1 consists of a lower housing 2 with a damping structure, a toggle assembly 3, and an upper housing 4. Currently, assembly in the industry generally relies on manual pressing by the operator. The operator first needs to use simple pliers to fix the lower housing 2, then install the toggle assembly 3 into the lower housing 4, and finally precisely align the upper housing 4 with the lower housing 2 before using the thumb and forefinger to apply force to tighten the toggle knob.

[0003] Regarding the aforementioned technologies, the assembly of the toggle switch 1 relies on manual pressing of the upper and lower housings using simple pliers. However, since the toggle switch 1 requires precise alignment, the operator may encounter situations where the upper housing 4 and lower housing 2 are not properly aligned during assembly, resulting in incomplete fastening. Furthermore, due to the small size of the toggle switch 1, the operator may damage it by applying excessive force during assembly. Therefore, the inventor believes that the current automotive air conditioning toggle switch 1 has a low assembly yield rate. Summary of the Invention

[0004] To address the problem of low yield rate during the assembly of automotive air conditioning toggle switches, this application provides an automotive air conditioning toggle switch assembly fixture.

[0005] The technical solution for the automotive air conditioning toggle assembly fixture provided in this application is as follows: A pedestal assembly includes a base and a first slot seat disposed on the base; The mounting base is vertically mounted on the base, and the mounting base has a vertically arranged linear guide rail on the side facing the base; The sliding fastening assembly includes a sliding seat mounted on the linear guide rail and sliding toward the first slot seat, a mounting plate rotatably connected to the sliding seat and rotating toward the first slot seat, and a second slot seat provided on the mounting plate; The spring return assembly includes a first spring for the sliding seat to slide and return to its original position, and a second spring for the mounting plate to rotate and return to its original position.

[0006] By adopting the above technical solution, when the operator assembles the car air conditioning toggle switch, the lower housing is first placed in the first slot, then the toggle assembly is placed in the lower housing, and then the upper housing is placed in the second slot. The mounting plate is then rotated to align the second slot with the first slot, and the sliding seat mounted on the linear guide rail is slid to engage the first and second slots, achieving the effect of fastening the upper and lower housings together. The interlocking of the slots ensures precise positioning, preventing damage to the toggle switch during assembly due to inaccurate positioning, and improving the yield rate of toggle switch assembly. After the toggle switch assembly is completed, the spring return assembly provides a force to the sliding seat and mounting plate to return to their initial positions, achieving automatic clamping and improving operator efficiency.

[0007] Optionally, the mounting plate includes a first connecting plate and a second connecting plate; the two sides of the first connecting plate are rotatably connected to the sliding seat through bearing seats, and the two sides of the first connecting plate are also provided with positioning plates for positioning the rotation angle and downward movement height of the first connecting plate; the lower end of the second connecting plate is provided on the upper end of the first connecting plate, the second slot seat is provided on the second connecting plate, and the upper end of the second connecting plate is also provided with a grip handle.

[0008] By adopting the above technical solution, the mounting plate includes a first connecting plate and a second connecting plate. When it is necessary to assemble and tighten the toggle switch, the mounting plate is rotated by pulling down the handle. One end of the positioning plate installed on both sides of the first connecting plate will abut against the bottom of the sliding seat, thereby restricting the mounting plate from rotating further and achieving precise positioning and assembly of the toggle switch. After the positioning plate abuts against the mounting plate, pulling down the handle further will cause the mounting plate to be moved downward by the sliding seat. At this time, the other side of the positioning plate will abut against the upper surface of the second fixing plate, thereby restricting the mounting plate from moving further downward and preventing excessive pressure caused by excessive downward movement of the mounting plate, which could damage the toggle switch.

[0009] Optionally, a spring connecting plate is also installed on the outer wall of the positioning plate, and the two ends of the first spring are respectively installed on the spring connecting plate and the upper end of the mounting base by the installed mounting pins.

[0010] By adopting the above technical solution, the first spring is connected to the spring connecting plate and the mounting base. When the mounting plate completes the fastening of the lever, the operator releases the handle. At this time, the first spring will rebound due to the tension of the prestress, and the mounting plate connected to the first spring will move upward and reset with the rebound of the first spring. At the same time, the mounting plate will drive the sliding seat to slide upward along the linear guide rail, thereby realizing that the sliding seat and the mounting plate can move upward and reset by the autonomous rebound of the first spring. This simplifies the operation steps of the operator controlling the fixture and improves the efficiency of assembling the lever.

[0011] Optionally, the spring connecting plate is also provided with a plurality of adjustment holes for the insertion of mounting pins.

[0012] By adopting the above technical solution, the first spring can be matched with different adjustment holes according to different models of toggle knobs to select a suitable installation position, avoiding the situation where the sliding seat rebounds too quickly and damages the clamp or fails to rebound properly due to excessive or insufficient spring tension prestress. This achieves the effect of controllable sliding seat rebound force.

[0013] Optionally, a spring positioning plate is provided at the upper end of the mounting base, and the two ends of the second spring are respectively mounted on the spring positioning plate and the lower end of the second connecting plate by the mounting positioning pins.

[0014] By adopting the above technical solution, the second spring is connected to the spring positioning plate and the second connecting plate. When the mounting plate is fastened to the lever, the operator releases the handle. At this time, the second spring will rebound due to the tension of the prestress. The second connecting plate connected to the second spring will drive the mounting plate to rotate relative to the sliding seat with the rebound of the second spring. This realizes that the mounting plate can rotate and reset relative to the sliding seat by relying on the autonomous rebound of the second spring, which simplifies the operation steps of the operator controlling the fixture and improves the efficiency of assembling the lever.

[0015] Optionally, the spring positioning plate is also provided with a plurality of positioning holes for the insertion of positioning pins.

[0016] By adopting the above technical solution, the second spring can be matched with different positioning holes according to different models of toggle switches to select a suitable installation position. This avoids the situation where the connecting plate rotates too quickly and damages the clamp or fails to rotate and reset properly when the mounting plate rotates relative to the sliding seat due to excessive or insufficient spring tension. This achieves the effect of controllable rotation and reset force of the mounting plate.

[0017] Optionally, the mounting base is provided with a limit block on the top of the linear guide rail.

[0018] By adopting the above technical solution, the limiting block can prevent the sliding seat from sliding off the linear guide rail due to excessive spring rebound prestress when the sliding seat is pulled upward by the first spring; at the same time, the limiting block can also prevent the mounting plate from rotating too fast due to excessive spring rebound prestress when the mounting plate rotates due to the rebound of the second spring, thus preventing damage to the mounting seat.

[0019] Optionally, a limiting groove is formed on the upper surface of the base, and a first fixing plate is installed in the limiting groove; a positioning groove is formed at the upper end of the first fixing plate, and a second fixing plate is provided in the positioning groove; both the first fixing plate and the second fixing plate are provided with waist-shaped mounting holes; the first card slot is installed on the second fixing plate.

[0020] By adopting the above technical solution, when the position of the first fixed plate needs to be moved, the bolts installed in the waist-shaped mounting holes are loosened and the first fixed plate is slid to the desired position, and then the bolts are tightened again. Similarly, the second fixed plate in the positioning groove is adjustable and fixed by installing bolts in the waist-shaped mounting holes. Therefore, when the size or assembly position of the toggle switch is different, the position of the first slot can be adjusted by moving the positions of the first and second fixed plates.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. In this application, the operator can quickly engage the toggle switch by using an integrated clamp, which improves the operator's engagement efficiency. Furthermore, the fixed slot can improve the positioning accuracy of the toggle switch during assembly, thereby increasing the assembly yield.

[0022] 2. This application achieves controllable elastic fastening and quick replacement and adaptation to different models of toggle switches through a spring buffer mechanism and modular slot design. Attached Figure Description

Then, the handle 27 is pulled to rotate the mounting plate 21 relative to the sliding seat 20. When the positioning plate 25 abuts against the sliding seat 20, pulling the handle 27 further will cause the sliding seat 20 to slide on the linear guide rail 16 until the positioning plate 25 abuts against the upper surface of the second fixing plate 15. At this point, the first slot 10 and the second slot 26 are engaged, thereby completing the clamping assembly of the upper and lower housings 2. After the toggle 1 is assembled, the operator only needs to release the handle 27. At this time, the sliding seat 20 and the mounting plate 21 will rebound due to the tension of the spring, thus moving upward and rotating back to their initial positions.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
