Description

Technical Field

[0001] This utility model relates to the field of passenger car seat technology, and in particular to an assembled lead screw slider for passenger car seats. Background Technology

[0002] Passenger car seats are the seats used when sitting in a car. Seats can be classified by shape as split seats and bench seats; by function as fixed seats, removable seats, and adjustable seats; and by the number of occupants as single, double, and multi-person seats. Based on the performance of the seats, they have evolved from the earliest fixed seats to multi-functional power adjustable seats, including air-cushioned seats, electric seats, stereo seats, recovery seats, and finally electronically adjustable seats. When producing adjustable seats, assembled screw sliders are used for adjustment.

[0003] The existing assembled screw sliders are mostly installed with numerous screws when assembled with seats. This assembly method requires workers to repeatedly turn the screws to disassemble and reassemble the seats during later maintenance and replacement, which increases the labor intensity of workers and reduces the efficiency of maintenance and replacement. Therefore, it has the defect of being inconvenient to disassemble and use, and thus cannot meet the needs of customers.

[0004] Therefore, those skilled in the art have provided a pre-assembled lead screw slider for passenger car seats to solve the problems mentioned in the background art. Utility Model Content

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] Example 1: Please refer to Figure 1-4 A prefabricated lead screw slider for passenger car seats includes a protective frame 1. Bearing seats 2 are fixedly connected to the left and right sides of the bottom of the inner cavity of the protective frame 1. A lead screw 3 is rotatably connected between the two bearing seats 2. A servo motor 4 is fixedly installed on the left side of the bottom of the inner cavity of the protective frame 1. One end of the lead screw 3 passes through the bearing seat 2 and is fixedly connected to the output end of the servo motor 4. A slider body 5 is threaded onto the outer surface of the lead screw 3. A rectangular frame 6 is fixedly connected to the top of the slider body 5. A positioning frame 7 is embedded in the top of the rectangular frame 6. An insert block 8 is inserted into the inner cavity of the positioning frame 7. The top of the insert block 8 extends to the outside of the positioning frame 7 and is fixedly connected to a mounting plate 9. Pin grooves 10 are provided on both the left and right sides of the insert block 8. Slide plates 11 are slidably connected to both the left and right sides of the inner cavity of the rectangular frame 6. One side of the slide plate 11 is fixed... A pin plate 12 is connected, with one end of the pin plate 12 extending into the inner cavity of the pin groove 10. A spring 13 is evenly fixedly connected to the side of the slide plate 11 away from the pin plate 12. One end of the spring 13 is fixedly connected to the connection point of the rectangular frame 6. A toggle assembly 14 is provided on the front of the slide plate 11. Slide tracks 16 are provided on the left and right sides of the top and bottom of the inner cavity of the rectangular frame 6. The inner surface of the slide track 16 is slidably connected to the inner surface of the slide plate 11. Mounting holes 17 are provided at the four corners of the top of the mounting plate 9. The bottom of the mounting plate 9 is tightly fitted to the connection point of the rectangular frame 6. A slide rail 18 is fixedly connected to the bottom of the inner cavity of the protective frame 1 and located inside the bearing seat 2. The outer surface of the slide rail 18 is slidably connected to the inner surface of the slider body 5. Mounting blocks are fixedly connected to the bottom of the left and right sides of the protective frame 1, and there are two mounting blocks.

[0032] In this embodiment: By setting up a protective frame 1, bearing seat 2, lead screw 3, servo motor 4 and slider body 5, this utility model can easily drive the passenger car seat to slide laterally back and forth. By setting up a rectangular frame 6, positioning frame 7, insert block 8, mounting plate 9, pin groove 10, sliding plate 11, pin plate 12 and spring 13, it can easily and quickly insert and assemble the passenger car seat. By setting up the above structure, it is easy to disassemble and use, thereby meeting the customer's usage needs.

[0033] Example 2: Refer to Figure 1 and Figure 3 The toggle assembly 14 includes a toggle post 141. The outer surface of the toggle post 141 is fixedly connected to the connection of the slide plate 11. The front of the toggle post 141 passes through the rectangular frame 6 and is fixedly connected to a toggle block 142. The outer surface of the toggle block 142 is slidably connected to the connection of the rectangular frame 6. The left and right sides of the front of the rectangular frame 6 are provided with moving grooves 15 that cooperate with the toggle post 141. The outer surface of the toggle post 141 is slidably connected to the inner surface of the moving groove 15.

[0034] In this embodiment: By setting the toggle post 141 and the toggle block 142, the present invention can facilitate the movement of the sliding plate 11.

[0035] The implementation principle of this utility model is as follows: In use, the operator uses the mounting block and screws to fix the device in a group at a designated position on the vehicle body. Then, the operator uses the mounting hole 17 and screws to fix the mounting plate 9 on the seat frame. When the seat needs to be assembled, the operator moves the seat frame, causing the seat frame to move the mounting plate 9 and the insert 8 downwards and insert them into the inner cavity of the positioning frame 7. At the same time as the insert 8 is inserted into the inner cavity of the positioning frame 7, the insert 8 presses the pin plate 12 to move, causing the pin plate 12 to move the slide plate 11 to slide on the inner surface of the slide rail 16 and press the spring 13. When the insert 8 is inserted into the designated position, the insert 8 moves the pin groove 10 to the position corresponding to the pin plate 12. At the same time, the spring 13 pushes the slide plate 11 to move in the opposite direction under the reaction force, causing the slide plate 11 to move the pin plate 12 in the opposite direction and insert it into the inner cavity of the pin groove 10, thereby limiting the connection between the insert plate and the positioning frame 7 and completing the assembly and installation of the seat frame.

[0036] When the seat needs to be adjusted and adapted, the staff activates the external controller of the servo motor 4, which causes the output end of the servo motor 4 to drive the lead screw 3 to rotate on the inner surface of the slider body 5. This causes the slider body 5 to move the rectangular frame 6, the positioning frame 7, the insert block 8 and the mounting plate 9, thereby causing the mounting plate 9 to move the seat and achieve the adjustment of the seat.

[0037] When the seat needs to be disassembled for inspection and replacement, the operator simultaneously moves the actuating blocks 142 on both sides, causing the actuating blocks 142 to move the actuating column 141 outward. At the same time, the actuating column 141 causes the sliding plate 11 to slide on the inner surface of the slide rail 16, compressing the spring 13. This causes the sliding plate 11 to move the pin plate 12 out of the inner cavity of the pin groove 10, thereby releasing the restriction on the insert block 8. Then, the operator moves the seat upward, causing the seat to move the mounting plate 9 and the insert block 8 upward away from the positioning frame 7, thus completing the quick disassembly of the seat. This device is simple to operate and easy to disassemble and use, thereby meeting the needs of customers.

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