[0001] The utility model relates to the field of automobile seat slide rail assembly, in particular to an automobile seat electric slide rail preassembly device. Background Art

[0002] Conventional technology involves assembling the upper and lower slide rails of automotive seats on a production line before packaging and shipping. However, finished slide rails can occasionally fail due to uneven lubrication of the rail screws and jamming of the electric slide rails, impacting product quality and stability. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the utility model develops a pre-assembly device for an electric slide rail of an automobile seat. The technical solution adopted by the present utility model is: a pre-assembly device for an electric slide rail of an automobile seat, characterized in that it includes a base 1, a slide rail fixing mechanism 2, a reflector 6, a guide rail 7, a motor bracket slider 8, a first corresponding radiation sensor 9, a second corresponding radiation sensor 10, a counterweight 11 and a buzzer 24; the slide rail fixing mechanism 2 includes an upper slide rail bracket 3 and a lower slide rail fixing block 5, both of which are fixedly arranged on the base 1 respectively; the side of the upper slide rail bracket 3 is fixedly connected to the magnet 4; the reflector 6 is fixedly arranged on the base 1 and is placed at the center position of the upper slide rail bracket 3 and on the same side as the magnet 4; the guide rail 7 is fixedly arranged on the base 1; the motor bracket slider 8 is slidably connected to the guide rail 7; the first corresponding radiation sensor 9 and the second corresponding radiation sensor 10 are respectively fixedly arranged at both ends of the base 1; the counterweight 11 includes a pin 12; the buzzer 24 is electrically connected to the first corresponding radiation sensor 9 and the second corresponding radiation sensor 10 respectively.

[0004] The benefits of the present invention are as follows: before the upper and lower slide rails of the car seat are formally assembled, a counterweight is used to press and insert the upper slide rail, gear box, and worm gear box, and the motor flexible shaft is quickly inserted into the gear box in conjunction with the reflector 6, so as to achieve pre-positioning and running-in of the upper and lower slide rails before assembly, which is conducive to discovering minor defects such as uneven lubrication of the slide rail screw rod and poor sticking of the electric slide rail before the upper and lower slide rails are formally assembled, so that they can be discovered and eliminated in time, avoiding abnormal noise and sticking of the product caused by minor defects, improving product stability and reducing customer complaints.

DETAILED DESCRIPTION

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] like Figure 1As shown, the utility model includes: a base 1, a slide rail fixing mechanism 2, a reflector 6, a guide rail 7, a motor bracket slider 8, a first corresponding beam sensor 9, a second corresponding beam sensor 10, a counterweight 11 and a buzzer 24; the slide rail fixing mechanism 2 includes an upper slide rail bracket 3 and a lower slide rail fixing block 5, both of which are fixedly arranged on the base 1 respectively; the side of the upper slide rail bracket 3 is fixedly connected to the magnet 4; the reflector 6 is fixedly arranged on the base 1 and is placed at the center position of the upper slide rail bracket 3 and on the same side as the magnet 4; the guide rail 7 is fixedly arranged on the base 1; the motor bracket slider 8 is slidably connected to the guide rail 7; the first corresponding beam sensor 9 and the second corresponding beam sensor 10 are respectively fixedly arranged at both ends of the base 1; the counterweight 11 includes a pin 12; the buzzer 24 is electrically connected to the first corresponding beam sensor 9 and the second corresponding beam sensor 10 respectively.

[0018] like Figure 1 As shown, two slide rail fixing mechanisms 2 and two reflectors 6 are provided on the base 1. The two slide rail fixing mechanisms 2 are arranged opposite to each other for pre-assembling the left and right slide rails at the same time. The motor bracket slider 8 is also placed in the center position of the slide rail fixing mechanism 2.

[0019] When doing specific operations, such as Figure 2 As shown, the worker first places the two lower rails 13 into the left and right lower rail fixing blocks 5. The threaded rod 14 is riveted into the lower rail 13. The threaded rod 14 is threadedly connected to the inner wall of the worm gear 16. The worm gear 16 is placed in the worm gear box 15. The structure and matching relationship of the lower rails, threaded rods, worm gears, and worm gear boxes are common knowledge. After the lower rails 13 are fixed, the worker sucks the left and right upper rails onto the magnets 4 of the upper rail bracket 3. Then, the worker places the gear box 18 into the square hole opened on the upper rail 17. Figure 3 As shown, the gear box 18 is placed only in the square hole of the upper slide rail on the right, and the square hole of the upper slide rail on the left is exposed for easy observation and comparison. The following description only takes the gear box 18 on the right as an example, and the principle on the left is exactly the same. Figure 4 As shown, a flexible shaft window 19 is provided on the upper slide rail 17 for inserting the flexible shaft, but the length of the square hole of the upper slide rail 17 is greater than the length of the lower portion of the gear box 18, so the flexible shaft jack in the gear box 18 is not exposed. Figure 5 As shown, the worker can adjust the relative position of the gear box 18 and the upper slide rail 17 by hand, and observe whether the flexible shaft socket 20 coincides with the flexible shaft window 19 by tilting the reflector 6 at about 45 degrees. Figure 6 As shown, the flexible shaft insertion hole 20 has overlapped with the flexible shaft window 19, and the flexible shaft insertion hole 20 is exposed. The advantage of the reflector 6 is that it is convenient for the worker to observe whether the flexible shaft insertion hole 20 is exposed by looking vertically downward, and it is also convenient for the subsequent flexible shaft insertion process without having to put the head between the two slide rails to directly observe.

[0020] like Figure 7 Shown, after the workman inserted the left and right two flexible shafts with motor 21, he placed in the motor bracket slide block 8, and manually inserted two flexible shafts in the flexible shaft jack 20. At this moment, the upper slide rail 17 is still attracted by the magnet 4 of the upper slide rail bracket 3.

[0021] like Figure 8 As shown, the worker presses the upper slide rail 17 downward to break away from the attraction of the magnet 4 and fall onto the lower slide rail 13. The worker presses the counterweight 11 onto the upper slide rail 17 and adjusts the relative positions of the upper slide rail 17 and the lower slide rail 13 so that the two pins 12 at the bottom of the counterweight 11 are respectively inserted into the corresponding threaded holes of the upper slide rail 17, the gear box 18 and the worm gear box 15. When the flexible shaft socket 20 is exposed in the flexible shaft window 19, the threaded holes of the upper slide rail 17 and the gear box 18 have overlapped.

[0022] The movement principle of the upper slide rail 17 is that the motor flexible shaft drives the worm 23 to rotate, the worm 23 drives the worm wheel 16 to rotate, and the worm wheel 16 moves back and forth along the threaded rod 14. The above principle is common knowledge.

[0023] like Figure 9 As shown, after pressing the left and right upper slide rails 17 with two counterweights 11 respectively, the worker can proceed to the next step, that is, turning on the power supply of the motor 21.

[0024] like Figure 10 As shown, the worker first rotates the motor 21 in the forward direction, causing the two upper rails 17 to move upward in the diagram. The motor 21, located within the motor bracket slider 8, moves simultaneously and in the same direction along the guide rail 7. When the upper end of the upper rail 17 is detected by the first through-beam sensor 9, the buzzer 24 sounds an alarm, indicating that the upper rail 17 is moving forward normally. Similarly, the worker then rotates the motor 21 in the reverse direction. When the second through-beam sensor 10 detects the lower end of the upper rail 17, the buzzer 24 sounds an alarm, indicating that the upper rail 17 is moving backward normally. During the forward and backward movement of the upper rail 17, if the worker discovers any defects, they can make timely adjustments to prevent minor defects from being passed to the next stage.

[0025] Finally, the workers will remove the pre-assembled and qualified upper and lower slide rails and send them to the next link.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
