[0035] The following further describes the present utility model in detail with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the convenience of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0036] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense.

The first feature being "below", "below", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the first feature is at a lower horizontal height than the second feature.

[0038] In the description of this embodiment, the terms "upper", "lower", "right", and other orientation or positional relationships are based on the orientation or positional relationship shown in the drawings. They are only for convenience of description and simplifying operations, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] Referring to Figures 1-8 As shown, in an embodiment of the present utility model, a storage device is proposed, which includes a drawer (not shown in the figure) and a housing 5. The housing 5 has a receiving area formed therein. The drawer is slidably disposed in the receiving area of the housing 5 and forms an access area on itself for storing items. The drawer can move between a closed position and an open position. In the closed position, the drawer is received in the receiving area; in the open position, the drawer is at least partially located outside the receiving area to facilitate the user to pick up and place items from the access area. In order to limit the sliding speed of the drawer when sliding between the open position and the closed position, the storage device further includes a damper, and the damper is installed in the receiving area of the housing 5 and contacts the drawer.

[0040] Referring to Figures 2-7 As shown, the damper includes a damper bracket 1, a damper 2, and a damper wheel 3. Among them, the damper 2 is a standard part of shaft-output type damper, including a damper body 21, a damper rotating shaft 23, and fixing ears 22. The two fixing ears 22 are oppositely arranged on the radial sides of the damper body 21, and the thickness of the fixing ears 22 along the axial direction of the damper body 21 is less than the thickness of the damper body 21. The damper rotating shaft 23 is connected to the damper body 21, and the damper wheel 3 is sleeved on the damper rotating shaft 23 to be connected to the damper 2. The damper wheel 3 has rolling friction with the drawer, and the damper 2 provides a damping torque for the damper wheel 3. The damper bracket 1 is an integrally formed injection molded part, including a main body portion 11. The main body portion 11 is provided with a first installation groove 111. At least part of the damper 2 is clamped and limited in the first installation groove 111, and the damper bracket 1 is connected to the housing 5.

[0041] The damper 2 in the above damper is clamped on the integrally formed damper bracket 1 by a clamping method. Compared with the separately arranged damper bracket 1, the mold opening cost of the damper bracket 1 is reduced, and the installation screws for connecting the separate damper brackets 1 are omitted. The whole damper and the storage device have a simple structure and are convenient to assemble.

[0042] In one embodiment, the damper bracket 1 is movably connected to the housing 5. The damper further includes an elastic member 4. The elastic member 4 is disposed between the housing 5 and the damper bracket 1 and abuts against or is connected to the damper bracket 1 to keep the damper bracket 1 in a tendency to move towards the drawer direction.

[0043] Specifically, the elastic member 4 adopts a compression spring. Referring toFigure 6 As shown, in order to reduce the stability of the connection or abutment between the compression spring as the elastic member 4 and the damping bracket 1, an installation portion 13 is further provided at the bottom of the damping bracket 1. The installation portion 13 can be inserted into the compression spring to limit the compression spring. In other embodiments, the elastic member 4 can also be an elastic gasket or the like.

[0044] The clamping and limiting of the damper 2 by the first installation groove 111 can be achieved by reasonably defining the size of the first installation groove 111, that is, making the damper 2 in interference fit with the first installation groove 111. Alternatively, a clamping block 1111 is provided in the first installation groove 111. The damper 2 can enter from the notch of the first installation groove 111 and squeeze the clamping block 1111 and is finally limited in the limiting space formed by the clamping block 1111 and the bottom of the first installation groove 111.

[0045] More specifically, two clamping blocks 1111 are arranged at intervals in a direction perpendicular to the axial direction of the damper 2, and the two clamping blocks 1111 respectively abut against the fixed ears 22 of the damper 2. The clamping block 1111 includes a first guiding surface and a second guiding surface. The first guiding surface is inclined on the upper surface of the clamping block 1111, and the second guiding surface is inclined on the lower surface of the clamping block 1111, so as to reduce the difficulty of taking out the damper 2 from the first installation groove 111 and facilitate the replacement and maintenance of the damper 2.

[0046] As Figures 5-7 shown, a second installation groove 112 is further provided on the main body portion 11. The second installation groove 112 has a notch in the same direction as the first installation groove 111, and the first installation groove 111 and the second installation groove 112 are connected through a communication port 113. The damping wheel 3 is installed in the second installation groove 112 and is connected to the damping shaft 23 of the damper 2. In order to reduce the difficulty of inserting the damping wheel 3 into the second installation groove 112, the width of the notch of the second installation groove 112 along the axial direction of the damper 2 decreases from top to bottom.

[0047] In one embodiment, the damping wheel 3 includes a hub 31 and an elastic ring 32. The elastic ring 32 is sleeved on the hub 31, and the hub 31 has a protruding portion protruding axially along the elastic ring 32. Specifically, the hub 31 is made of plastic such as PC-ABS, the elastic ring 32 is coated outside the hub 31, and the elastic ring 32 is made of soft rubber such as TPE material. Specifically, the damping wheel 3 as a whole can be processed by a two-color injection molding process.

[0048] Based on the setting that the hub 31 has a protruding portion, a jack 114 is also provided through the groove wall on the side of the second installation groove 112 far from the damper 2, that is, far from the first installation groove 111. The protruding portion is inserted into the jack 114 to form a rotating pair with the damping bracket 1.

[0049] To guide the installation of the damping wheel 3 and reduce the difficulty of inserting the protruding part into the jack 114, a guiding part 14 is provided on the inner wall of the second installation groove 112 on the side away from the first installation groove 111. The guiding part 14 has a guiding channel, and the guiding opening of the guiding channel is in the same direction as the notch of the second installation groove 112. The jack 114 is located in the guiding channel.

[0050] Specifically, to reduce the difficulty of the protruding part entering the guiding channel, the guiding channel gradually converges from the notch direction of the second installation groove 112 towards the bottom of the second installation groove 112. For example, the guiding part 14 is arranged in a V shape to form a V-shaped guiding channel, or the guiding part 14 can also be arranged in an inverted V shape to form a flared guiding channel.

[0051] In one embodiment, the side of the first installation groove 111 facing away from the second installation groove 112 is open, and the first installation groove 111 further includes a clamping elastic piece 1112. The clamping elastic piece 1112 is arranged at the opening of the first installation groove 111 and the width of the clamping elastic piece 1112 is smaller than the width of the opening, that is, there are gaps between the opposite two sides of the clamping elastic piece 1112 perpendicular to the axis of the damper 2 and the groove wall of the first installation groove 111. When the damping wheel 3 connected to the damper 2 is inserted into the second installation groove 112 from the notch of the second installation groove 112, the clamping elastic piece 1112 is deformed by the extrusion of the damper 2. After the protruding part is inserted into the jack 114, the clamping elastic piece 1112 can cooperate with the groove wall of the first installation groove 111 close to the damping wheel 3 to clamp the damper 2.

[0052] It should be noted that when the two clamping blocks 1111 are arranged on the groove wall of the first installation groove 111 close to the second installation groove 112, the clamping blocks 1111 and the clamping elastic piece 1112 are arranged in a staggered manner in the axial direction of the damper 2 to reduce the difficulty of the damper 2 being clamped into the limiting space. Of course, the two clamping blocks 1111 can also be respectively arranged on the groove walls of the opposite two sides of the first installation groove 111 perpendicular to the axial direction of the damper 2.

[0053] More specifically, to improve the structural strength of the clamping elastic piece 1112, a reinforcing rib is further provided at the end of the clamping elastic piece 1112 connected to the bottom of the first installation groove 111. The reinforcing rib is specifically arranged on the side of the clamping elastic piece 1112 facing away from the damper 2 to avoid affecting the insertion of the damper 2 into the first installation groove 111.

[0054] In one embodiment, the damping bracket 1 further includes a rotating part 12. The rotating part 12 has an axis same as the axis of the damper 2. The damping bracket 1 is rotatably installed on the housing 5 through the rotating part 12.

[0055] Reference Figures 2-4As shown, in one embodiment, two mounting seats 51 are provided on the housing 5 and are integrally molded with the housing 5. The two axial ends of the rotating part 12 are respectively inserted into the two mounting seats 51 to achieve axial limiting. Specifically, each mounting seat 51 is provided with a third mounting groove 511 for inserting the rotating part 12. In order to reduce the difficulty of inserting the two axial ends of the rotating part 12 into the two mounting seats 51, the third mounting groove 511 has a first opening in the same direction as the first mounting groove 111 and the second mounting groove 112 and a second opening facing another third mounting groove 511. The rotating part 12 can enter the third mounting groove 511 through the first opening, and can also be separated from the third mounting groove 511 through the first opening.

[0056] It should be emphasized that the damping bracket 1 includes an installation position and a working position relative to the shell 5, and the switching of the damping bracket 1 between the installation position and the working position is achieved by rotating the rotating part 12; when in the working position, the rotating part 12 is limited in the third mounting groove 511 and can rotate relative to the mounting seat 51, and when in the installation position, the rotating part 12 can disengage from the third mounting groove 511 from the first opening. Restricted by the elastic member 4 and the drawer, the rotating part 12 can rotate less than 90° after being assembled on the mounting seat 51. When and only when the damping wheel 3 is not restricted by the drawer, the rotating part 12 can rotate to switch the damping bracket 1 from the working position to the installation position to disengage from the third mounting groove 511.

[0057] For example, the third mounting groove 511 is configured as a major arc groove, the outer peripheral surfaces at both axial ends of the rotating part 12 each include two parallel planes, the two parallel planes are connected by two arc surfaces, the distance between the two parallel planes at the same end of the rotating part 12 is less than the width of the first opening, and the maximum distance between the two arc surfaces is greater than the width of the first opening; or, the third mounting groove 511 is configured as a major arc groove, the circumferential profile of at least the two axial ends of the rotating part 12 is configured as an ellipse, and the width of the first opening is greater than the short axis of the ellipse but less than the long axis of the ellipse. The above two configurations of the rotating part 12 can improve the smoothness of the rotating part 12 rotating in the third mounting groove 511.

[0058] Alternatively, refer to Figure 8 As shown, the third installation slot 511 is configured as a U-shaped slot, and a limiting block 5111 is also disposed in the third installation slot 511 . The two limiting blocks 5111 are respectively disposed on opposite sides of the third installation slot 511 to limit the rotating portion 12 .

[0059] In other embodiments, the damper is slidably disposed on the housing 5 so as to be able to make a linear motion relative to the housing 5 towards or away from the drawer, thereby maintaining contact with the drawer under the action of the elastic member 4 .

[0060] In an embodiment of the present utility model, a vehicle is further provided, which includes a vehicle body and the storage device in any of the above embodiments. The storage device can be disposed at any place on the vehicle body where it is allowed and accessible to passengers. For example, it can be located between the driver's seat and the passenger's seat, i.e., behind the instrument panel or on the co-pilot side of the instrument panel.

[0061] Since the vehicle has the storage device in any of the above embodiments, it has all the beneficial effects of the storage device, which will not be elaborated here.

[0062] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modification, equivalent substitution, and improvement made within the spirit and principle of the present utility model shall be included in the protection scope of the claims of the present utility model.
