Description

Technical Field

[0001] The utility model relates to the technical field of automobile armrest bracket processing, in particular to an automobile armrest bracket with a damping device. Background Technique

[0002] Currently, more and more rear seats of automobiles need to have the function of armrests. The comfort of the armrests during use is an important indicator to measure the quality of the seats, such as the magnitude of the operating force, noise, etc. Therefore, it is crucial to control the operating force and the movement process when the armrest is folded.

[0003] The existing automobile armrest bracket processing technology often adopts an automobile armrest bracket with a damping device disclosed in Chinese Utility Model Patent No. CN205292348U. It makes the armrest rotating shaft and the convex ribs of the plastic damping bushing in interference fit through a pair of convex ribs and the armrest rotating shaft. When the armrest approaches the horizontal use position or the erected position, the interference fit between the armrest rotating shaft and the convex ribs of the plastic damping bushing increases the adjusting force, extrudes the convex ribs, and feeds back to the operator to achieve the feel at the near-horizontal limit position or the erected position, so that the movement of the armrest can be smooth and the noise can be eliminated. However, the body types of users are different, and the height requirements for the armrests will also be different. And this device can only be flipped and cannot adjust the height, thus affecting the comfort of users. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the height cannot be freely adjusted in the prior art, and to propose an automobile armrest bracket with a damping device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An automobile armrest bracket with a damping device includes a bracket and an armrest installed in the middle position of the rear seat of the automobile. An electric telescopic rod is fixedly installed on the rear seat of the automobile, and a deflection mechanism for controlling the deflection of the bracket is arranged on the rear seat of the automobile;

[0007] A first shaft seat is welded inside the bracket, and second shaft seats are welded on the bracket at both ends of the first shaft seat. A driving motor is fixedly installed at the bottom end of the first shaft seat, and an adjusting mechanism for adjusting the height of the armrest is arranged inside the bracket.

[0008] Preferably, a rotating shaft is connected between the rear seat of the automobile and the bracket, and the two second shaft seats are equidistantly distributed at both ends of the first shaft seat.

[0009] Preferably, the deflection mechanism includes a slide rail fixedly installed on the rear seat of the automobile. A driving rack connected with the electric telescopic rod is slidably installed on the slide rail, and a driven gear meshed with the driving rack is fixedly installed on the rotating shaft.

[0010] Preferably, the adjusting mechanism includes four groups of support columns welded to the bracket. A worm gear connected to the output end of the driving motor is installed on the first shaft seat in a matching manner. Two center shafts passing through the outside of the second shaft seat are movably installed between the first shaft seat and the second shaft seat, and worm wheels meshing with the worm gear are fixedly installed on the center shafts. Connecting rods are fixedly installed at the free ends of the two center shafts;

[0011] Four groups of sliding columns matched with the connecting rods are slidably installed in the support columns, and handrails are fixedly installed on the sliding columns.

[0012] Preferably, the connecting rod is slidably sleeved at the lower end of the sliding column, and rectangular through holes are formed in the support columns.

[0013] Preferably, a traction long hole is formed in the connecting rod, a plastic damping bushing is installed in the traction long hole in a matching manner, and a traction long bolt slidably sleeved in the traction long hole is integrally connected to the lower end of the connecting rod.

[0014] Compared with the prior art, the present utility model has the following advantages:

[0015] 1. The present utility model controls the bracket to deflect through the electric telescopic rod. When the handrail needs to be used, the electric telescopic rod is controlled to contract, and the bracket originally vertically installed on the back seat of the car will flip downward by 90°, making the handrail parallel to the seat cushion.

[0016] 2. By rotating the driving motor clockwise, the present utility model can synchronously control the four groups of sliding columns to extend upward, so that the height of the handrail can be freely adjusted according to the needs of the user to improve the comfort of the user.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer to Figures 1 - 4 , an armrest bracket for a car with a damping device, including a bracket 1 and an armrest 7 installed in the middle position of the rear seat 2 of the car. A rotating shaft 8 is connected between the rear seat 2 of the car and the bracket 1. The rotating shaft 8 is installed at a position slightly below the center of the bracket 1, which can prevent the bracket 1 from contacting the seat cushion of the rear seat 2 when deflecting. An electric telescopic rod 3 is fixedly installed on the rear seat 2 of the car, and a deflection mechanism for controlling the flipping of the bracket 1 is provided on the rear seat 2 of the car;

[0024] A first shaft seat 4 is welded inside the bracket 1, and second shaft seats 5 are welded on the bracket 1 at both ends of the first shaft seat 4. The two groups of second shaft seats 5 are equidistantly distributed at both ends of the first shaft seat 4, and the two groups of second shaft seats 5 and the first shaft seat 4 are on the same horizontal line. A driving motor 6 is fixedly installed at the bottom end of the first shaft seat 4. An adjusting mechanism for adjusting the height of the armrest 7 is provided inside the bracket 1. Control buttons for controlling the electric telescopic rod 3 and the driving motor 6 are provided on the car, and the operation of the deflection mechanism and the adjusting mechanism can be controlled with one key.

[0025] The deflection mechanism includes a slide rail 9 fixedly installed on the rear seat 2 of the car. A driving rack 10 connected to the electric telescopic rod 3 is slidably installed on the slide rail 9. A driven gear 11 meshing with the driving rack 10 is fixedly installed on the rotating shaft 8. The electric telescopic rod 3 has a fixed stroke range, and accurately controls the deflection angle of the bracket 1 within 90°.

[0026] The adjusting mechanism includes four groups of support columns 15 welded to the bracket 1. A rectangular through-hole 18 is provided on the support column 15. A worm 12 connected to the output end of the driving motor 6 is installed on the first shaft seat 4 in a matching manner. Two groups of central shafts 13 passing through the outside of the second shaft seat 5 are movably installed between the first shaft seat 4 and the second shaft seat 5. A worm gear 14 meshed with the worm 12 is fixedly installed on the central shaft 13. The two groups of worm gears 14 are on both sides of the worm 12. When the worm 12 rotates, the worm gears 14 make rotational movements in opposite directions. Connecting rods 16 are fixedly installed at the free ends of the two groups of central shafts 13. Slide columns 17 connected to the connecting rods 16 in a matching manner are slidably installed in the four groups of support columns 15.
