Technical Field

[0001] This utility model belongs to the field of automotive seats, specifically relating to a foldable armrest display rack with damping function. Background Technology

[0002] As competition intensifies in the domestic automotive industry, the demands for comfort and usability in car interiors are increasing. To reduce the space occupied by seat armrests, foldable armrests are generally adopted. When not in use, the armrest assembly can be folded upwards to increase the car's interior space; when in use, the armrest assembly can be folded down to provide support for the arms.

[0003] Foldable armrests need to be displayed during sales, promotion, and testing. Currently, foldable armrests are directly installed on seats for display. However, seats are large and heavy, making them inconvenient to move for display. Furthermore, foldable armrests have the problem of falling too quickly, thus reducing the comfort of the armrest assembly. Utility Model Content

[0004] The purpose of this invention is to solve the aforementioned problems by providing a foldable handrail display rack with a damping function. The foldable handrail has a one-way rotation damper on the side of the handrail frame away from the adjustment section. This one-way rotation damper solves the problem of excessive speed during the descent of the foldable handrail. Simultaneously, the handrail assembly with the one-way rotation damper is rotatably connected to the display rack via a pivot. The display rack has a simple and lightweight structure, making it more convenient to display the handrail assembly.

[0005] To achieve the above objectives, this utility model provides a foldable handrail display rack with damping function, including a display rack and a handrail assembly rotatably connected to the display rack. The display rack includes a base, and a support frame is provided in the middle of the base and vertically connected thereto. A rotating shaft is provided on one side of the top of the support frame and rotatably connected to the handrail assembly. One end of the rotating shaft near the support frame is a connecting part, and the rotating shaft is connected to the support frame through the connecting part. The other end of the connecting part is connected to the step shaft through a spline part.

[0006] Advantages and beneficial effects of this utility model

[0007] 1. The display rack in this utility model has a simple and lightweight structure, which is more convenient and faster to move and display than the armrest assembly installed on the seat. At the same time, this application has a reinforcing bracket fixed between the support frame and the pivot, which increases the lever arm length of the pivot and makes the display rack more stable.

[0008] 2. This utility model adds a one-way rotation damper to the handrail frame. The one-way rotation damper can provide one-way damping force to the handrail assembly, preventing the handrail assembly from falling too fast and improving the user's comfort experience of the handrail assembly.

[0019] like Figure 1 and Figure 2 As shown, a foldable armrest display rack with damping function includes a display rack 1 and an armrest assembly 2 rotatably connected to the display rack 1. The display rack 1 includes a base 11, and a support frame 12 perpendicularly connected to the base 11 is provided at the top center of the base 11. The support frame 12 is welded together from a first support frame 121 and a second support frame 122. The first support frame 121 and the second support frame 122 are two U-shaped brackets. A pivot 13 is welded to the upper right side of the first support frame 121. In order to facilitate the connection part 131 of the pivot 13 through the first support frame 121 and welded into the U-shaped cavity of the first support frame 121, the second support frame 122 has a clearance opening 123 at the position relative to the pivot 13. In order to increase the connection area between the support frame 12 and the base 11, so that the support frame 12 can be more stably connected to the top of the base 11, the bottom of the first support frame 121 and the second support frame 122 has an outwardly bent second flange 124. The second flange 124 is detachably connected to the base 11 by bolts. The base 11 has four feet 15 bolted to its four corners. When the display surface is uneven or the display stand is tilted, the height of the bolts on the four feet can be adjusted to make the display stand level.

[0020] like Figure 2As shown, the end of the rotating shaft 13 near the support frame 12 is a connecting part 131. The rotating shaft 13 is fixedly connected to the support frame 12 through the connecting part 131. The other end of the rotating shaft 13 is designed to mimic the spline shaft on a seat, allowing the armrest assembly 2 to be rotatably connected to the display rack 1 via the rotating shaft 13. This includes a spline part 132 and a stepped shaft 133. When the armrest assembly 2 is connected to the rotating shaft 13, the first round shaft 1331 on the stepped shaft 133 is interference-fitted with the one-way rotation damper 24, the second round shaft 1332 on the stepped shaft 133 is fitted with the armrest frame 22, and the spline part 132 is fitted with the adjustment part 23.

[0021] like Figure 2 and Figure 3 As shown, in order to increase the lever arm length of the rotating shaft 13 and distribute the load-bearing pressure, this application adds a reinforcing bracket 14 between the support frame 12 and the rotating shaft 13. The reinforcing bracket 14 includes a bracket body 141, and the bracket body 141 has first flanges 142 bent towards the support frame 12 around its perimeter. The reinforcing bracket 14 is welded to the support frame 12 through the first flanges 142. The bracket body 141 has a reinforcing platform 143 protruding away from the support frame 12 at a position relative to the rotating shaft 13. The reinforcing platform 143 has a through hole 144 in the middle to facilitate the passage of the rotating shaft 13. By adding the reinforcing bracket 14, the load-bearing capacity of the display rack 1 is improved.

[0022] like Figures 4-6 As shown, the armrest assembly 2 includes an upper armrest cover assembly 21, an armrest frame 22, an adjustment part 23, a one-way rotation damper 24, and a lower armrest cover assembly 25. The upper armrest cover assembly 21 and the lower armrest cover assembly 25 are snapped together to form a mounting cavity for installing the armrest frame 22, the adjustment part 23, and the one-way rotation damper 24. The armrest frame 22 has an adjustment part 23 (an existing structure, which can be found in application number 2023235162504, entitled "An Ultra-Thin Multi-Gear Flip-Up Armrest") on one side near the support frame 12 for adjusting the angle of the armrest assembly. The adjustment part in the folding armrest mechanism can also be the locking device in the armrest locking device for automobile seats (application number 2018108182862, name: locking device for automobile seat armrest locking device, etc., as long as it can realize the multi-position adjustment and locking of the armrest assembly). The side of the armrest frame 22 away from the adjustment part 23 is connected to a one-way rotation damper 24 by screws. The one-way rotation damper 24 only generates damping force when rotating in the direction of the arrow. When the armrest assembly 2 is connected to the rotating shaft 13, the rotating shaft 13 passes through the adjustment part 23, the armrest frame 22 and the one-way rotation damper 24 in sequence.

[0023] The unidirectional rotation damper 24 is an existing structure, therefore, this application will not describe the specific structure of the unidirectional rotation damper in detail, but only describe how it generates damping to decelerate the handrail during downward rotation.

[0024] The one-way rotation damper 24 is connected to the handrail frame 22 by screws. The shaft 241 in the middle of the one-way rotation damper 24 has a shaft hole 242 that mates with the rotating shaft 13. The first round shaft 1331 of the rotating shaft 13 is inserted into the shaft hole 242 and is interference-fitted with the shaft hole. When the handrail is lowered, the rotating shaft 13 and the shaft 241 do not move. The rest of the one-way rotation damper 24 rotates downward along the direction of the arrow with the handrail assembly 2 and generates a damping force, thereby reducing the falling speed of the handrail assembly 2. When the handrail assembly is raised, the one-way rotation damper 24 does not generate a damping force, and the handrail assembly 2 can be raised normally.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the present utility model.
