[0002] With the development of the automobile industry, end users have more and more functional requirements for vehicle interior products. People not only consider general functionality, but also realize more functions in a limited space, which is an important demand of users for luxury brand high-end vehicles. The central armrest of the car not only provides support for the passenger's elbows after the upper cover assembly is closed, but also needs to have the function of storage, so the upper cover assembly needs to rotate relative to the storage box to facilitate the driver and passengers to take and put items from the storage box. Since the upper cover assembly has the problem of free fall during the opening and closing process, it is difficult to ensure that the upper cover assembly will not close under the action of gravity and hit the driver and passengers after opening it. At the same time, the upper cover assembly will collide with the storage box after free fall to produce noise, thereby reducing the experience of the driver and passengers.

[0003] In order to solve the above problems, the existing design will add two damping hinges between the upper cover assembly and the storage box. The two damping hinges can make the upper cover assembly slowly drop when closed, and will not bounce up and cause vibration after opening. However, the connection through two damping hinges has the following problems:

[0004] 1. Since the storage box body is too large to be inlaid and injection molded together with the upper cover assembly and the damping hinge, it is necessary to separate a part of the structure (the shaft bracket) on the storage box from the box body, and then inlay and injection mold the shaft bracket, two damping hinges and the upper cover assembly together, and then connect them to the box body with screws after injection molding. Therefore, the production process is complicated;

[0005] 2. Since the upper cover assembly, two damping hinges and the pivot bracket are formed into an integrated structure through inlay injection molding, they are non-detachable. When the damping hinge fails, it cannot be replaced alone. The upper cover assembly and the pivot bracket need to be replaced together. At the same time, if there are defects or scratches on the appearance of a part, the entire set of parts will be scrapped.

[0006] 3. The cost of the two damping hinges is high, which increases the production cost. Utility Model Content

[0020] Advantages and beneficial effects of the utility model

[0021] 1. The utility model is provided with a torsion spring and a damper between the upper cover assembly and the storage box. When the upper cover assembly is closed relative to the storage box, the torsion spring is compressed to generate a counterclockwise torque. At the same time, the damping plate in the damper rotates relative to the damping shell, thereby generating friction. With the cooperation of the torsion spring and the damper, the upper cover assembly can be slowly lowered. When the upper cover assembly is opened, the upper cover assembly rotates counterclockwise relative to the storage box. At this time, although the torsion spring gradually changes from a compressed state to an extended state, due to the friction generated by the damper, the upper cover assembly will not bounce up after opening, resulting in vibration.

[0022] 2. In the utility model, the upper cover assembly and the storage box are rotatably connected via a rotating shaft. Therefore, there is no need to inlay and injection-mold the upper cover assembly, the damping hinge and a part of the storage box into one piece and then connect them to the box body via screws as in the existing design. The process is simpler.

[0023] 3. In the utility model, the upper cover assembly is detachably connected to the storage box through a rotating shaft. When the damper or torsion spring fails, they can be replaced separately. The cost of the damper and torsion spring is relatively low, about ten yuan per set, while the cost of two damping hinges in the existing design is more than thirty yuan and cannot be replaced separately. Therefore, the cost of the present application is lower, saving production costs.

[0024] 4. In actual vehicle installation and matching, the utility model can select dampers and torsion springs with different torque values ​​according to actual needs, and the damper and torsion spring are arranged in the middle installation part of the upper cover assembly, so that the upper cover assembly slowly descends when closing and does not bounce when opening, without damaging the appearance of the central armrest.

[0042] This application is based on Figure 3-Figure 5The upper cover assembly 1 is described in detail. The upper cover assembly 1 includes an upper cover component 110, an unlocking button component 120 and an upper cover outer plate 130. The upper cover component 110 includes an upper cover inner plate 111, and the upper cover inner plate 111 is covered with an upper cover foam 112 and an upper cover skin 113. The upper cover component 110 is provided with an unlocking hole 114. The upper cover outer plate 130 is provided with a first mounting cavity 131 at a position relative to the unlocking hole 114. The unlocking button component 120 is provided in the first mounting cavity 131. The upper cover component 110 and the upper cover inner plate 111 are provided with a first mounting cavity 131. After the cover outer panel 130 is welded, the unlocking button on the unlocking button assembly 120 is exposed to the outside through the unlocking hole 114, so that the driver and passengers can press the unlocking button to drive the unlocking button assembly 120 to unlock the storage box 2. The first torsion arm 301 on the torsion spring 3 is inserted between the upper cover assembly 110 and the upper cover outer panel 130 through the through hole on the middle mounting part 102. The middle mounting part 102 is provided with a limiting groove 1022 at the bottom of one end of the damper 4. The damper housing 401 is connected to the middle mounting part 102 through the limiting groove 1022.

[0043] like Figure 2 , Figure 3 and Figure 6 As shown, the storage box 2 has a connecting portion 201 protruding outward and a blocking platform 206 preventing the upper cover assembly from infinitely rotating counterclockwise on one side close to the upper cover assembly 1, and a mounting portion avoidance groove 202 is provided on the connecting portion 201 relative to the middle mounting portion 102, so that the connecting portions 201 on both sides of the mounting portion avoidance groove 202 form a left connecting ear 203 and a right connecting ear 204, and the left connecting ear 203 and the right connecting ear 204 correspond to the positions of the avoidance groove 104 on the upper cover assembly 1, and the second torsion arm 302 of the torsion spring 3 is inserted into the left connecting ear 203 through a through hole, and a card slot 2041 is provided on the side of the right connecting ear 204 relative to the damper 4, and a rotating shaft 5 is provided at the opposite ends of the left connecting ear 203 and the right connecting ear 204, and the storage box 2 is rotatably connected to the left mounting portion 101 and the right mounting portion 103 on the upper cover assembly 1 through the rotating shafts 5 on both sides.

[0044] like Figure 6 As shown, a torsion arm avoidance groove 2031 is provided on the left side of the inner end of the left connecting ear 203, so that a shielding arm 2032 is formed on the right side of the inner end of the left connecting ear 203, and the second torsion arm 302 of the torsion spring 3 is arranged in the torsion arm avoidance groove 2031, and the end of the second torsion arm 302 passes through the through hole at the bottom of the torsion arm avoidance groove 2031 and is inserted into the left connecting ear 203. Therefore, by shielding the second torsion arm 302 with the shielding arm 2032, the torsion spring 3 will not be exposed and affect the appearance after the upper cover assembly 1 is connected to the storage box 2.

[0045] like Figure 3 and Figure 7As shown, the damper 4 includes a damper housing 401, a damper shaft 402 and a plurality of damper plates, the plurality of damper plates are attached to each other and hold the damper shaft 402 tightly, the damper housing 401 wraps the plurality of damper plates and directional installs the rocker arms of the plurality of damper plates, a limiting strip 4011 is provided on one side of the damper housing 401, and the damper housing 401 is connected to the middle mounting portion 102 through the mutual cooperation between the limiting strip 4011 and the limiting groove 1022. One end of the damper shaft 402 is provided with a limit platform 4021, and the damper shaft 402 is connected to the right connecting ear 204 on the storage box 2 through the mutual cooperation between the limit platform 4021 and the card slot 2014. When the upper cover assembly 1 rotates relative to the storage box 2, the upper cover assembly 1 will drive the damper housing 401 to rotate relative to the damper shaft 402 and the multiple damping plates thereon, and the damping function is realized by the friction generated by the damper housing 401 and the multiple damping plates.

[0046] As a further optimization, the unlocking structure includes an unlocking button assembly 120 and an unlocking pop-up assembly, wherein the unlocking button assembly 120 includes an unlocking button, a guide block, a lock tongue and a return spring, a guide block is provided at the bottom of the unlocking button, and two guide arms are provided on the opposite sides of the bottom of the guide block, and the opposite sides of the guide arms are provided with two guide surfaces inclined outward, and two relatively movable lock tongues are provided between the two guide surfaces, and a return spring is provided between the two lock tongues, and the two lock tongues are provided with lock hooks on the opposite sides of the two lock tongues, and the lock hooks pass through the side walls of the first mounting cavity 131 and are exposed to the outside; when unlocking, the unlocking button is pressed, and the unlocking button leads the lock tongues on the opposite sides of the guide block to move downward, and at this time, the guide surfaces on both sides of the guide block press the lock tongues on both sides to move inward relative to each other, thereby causing the lock hook to disengage from the lock hole of the first mounting cavity 131 on the storage box 2.

[0047] The unlock pop-up assembly facilitates unlocking the storage box 2 through the unlock button assembly 120, so that the upper cover assembly pops up relative to the storage box under the action of the unlock pop-up assembly. The unlock pop-up assembly is arranged in a second mounting cavity at one end of the storage box 2, and the position of the second mounting cavity corresponds to the position of the first mounting cavity 131.

When the upper cover assembly is closed, the unlock button assembly 120 makes the two longitudinal springs pop up through the pressure plate. The spring arranged in the direction is in a compressed state. When the upper cover assembly is unlocked by the unlocking button assembly 120, the upper cover assembly 1 pops up under the action of the unlocking pop-up assembly, which is convenient for the driver and passengers to flip over the upper cover assembly 1. Since the present application also provides a torsion spring 3 between the upper cover assembly 1 and the storage box 2, when the upper cover assembly 1 pops up under the action of the unlocking pop-up assembly, the torsion spring 3 gradually changes from a compressed state to a telescopic state, thereby generating a counterclockwise torque, which can further help the upper cover assembly 1 to pop up relative to the storage box 2, reducing the pop-up force of the upper cover assembly 1 due to the damper 4.

[0048] As a further optimization, two buffer rubber nails 6 are provided at the front end of the side of the upper cover assembly 1 opposite to the storage box 2. When the upper cover assembly 1 is closed, the buffer rubber nails 6 are against the storage box 2.

On the other hand, they can prevent the upper cover assembly 1 from shaking relative to the storage box 2 on bumpy roads, thereby generating abnormal noise.

[0049] As a further optimization, a felt is provided at a position of the upper cover assembly 1 relative to the first torsion arm 301, and a felt is wrapped on the second torsion arm 302. When the upper cover assembly 1 is closed or opened, the first torsion arm 301 of the torsion spring 3 will move or rub relative to the upper cover assembly 1, and the second torsion arm 302 of the torsion spring 3 will move or rub relative to the left connecting ear 203 on the storage box 2, so an abnormal noise will be generated. Therefore, the present application provides a felt at a position of the upper cover assembly 1 relative to the first torsion arm 301, and a felt is wrapped on the second torsion arm 302 of the torsion spring 3, thereby solving the abnormal noise caused by the movement or friction of the torsion spring 3 relative to the upper cover assembly 1 and the storage box 2 when the upper cover assembly 1 is closed or opened.
