Description
Technical Field
[0001] The utility model relates to the field of automobile interiors, and particularly to a roller damping structure, a storage box and an automobile. Background Art
[0002] The storage box is an important interior structure in an automobile. At present, a drawer-type storage box is provided in an automobile. The storage box includes a box body and a box cavity. A chamber for accommodating the box cavity is provided on the box body. The box cavity is slidably located in the chamber, and the box cavity is slidably connected to the chamber through a slide rail. When the storage box needs to be opened, the box cavity is pulled out of the chamber by a part, so that the storage box is opened, and items can be placed and taken in the box cavity. When the storage box needs to be closed, the box cavity is pushed into the box body.
[0003] At present, a damping structure is provided between the box cavity and the box body. Through the damping structure, the box cavity can move stably in the box body. When the box cavity slides in the chamber, it is relatively slow and stable, and at the same time, after the box cavity is pulled out of the box body, it can maintain a stable static state at any position.
[0004] The current damping structure is a gear-rack type damping structure, which includes a damper, a gear and a rack. The gear is coaxially connected to the damper, the gear meshes with the rack, the rack is connected to one of the box cavity or the box body structures, and the damper is fixed to the other of the box cavity or the box body structures. When the box cavity moves, the gear and the rack move relative to each other. However, this damping structure has the following disadvantages: when the load in the box cavity is large, the box cavity deforms, which will cause the gear and the rack to mesh and deviate and fail (after the box cavity deforms, the gear and the rack cannot mesh normally), so that the damping structure fails and cannot play a damping role. Summary of the Utility Model
[0005] The utility model aims to provide a roller damping structure, a storage box and an automobile, so as to improve the load-bearing capacity of the box cavity, so that after the load-bearing of the box cavity is increased, the damping structure will not fail and can still work normally.
[0006] To achieve the above object, the utility model adopts the following technical scheme: a roller damping structure, including a roller frame, a rotary damper is fixedly installed on the roller frame, a roller is coaxially connected to the rotary damper, and the roller is rotatably connected to the roller frame.
[0007] To achieve the above object, the utility model adopts the following technical scheme: a storage box, including a box body and a box cavity, a chamber is provided on the box body, the box cavity is slidably located in the chamber, and the above-mentioned roller damping structure is provided between the bottom of the box cavity and the bottom of the chamber;
[0008] The roller frame is installed at the bottom of the chamber, and the roller abuts against the bottom of the box cavity; or,
[0009] The roller stand is installed at the bottom of the box body, and the roller abuts against the bottom of the chamber.
[0010] To achieve the above object, the utility model adopts the following technical solution: an automobile, including the above storage box.
[0011] The principle and advantages of the present application solution are as follows: The inventor of the present application designed a roller damping structure, which is used for two relatively sliding objects. When in use, the roller stand is fixed on one of the objects, and the roller abuts against the other object. When the two objects slide relative to each other, the roller rolls on the external object. Since a rotary damper is connected to the roller, the roller rolls on the external object relatively stably and slowly, so that the relative sliding of the two objects is relatively smooth and slow. At the same time, when the roller is in a static state, the roller will not rotate automatically, and the roller can be in a stable static state, so that the two objects can be in a stable static state.
[0012] Applying the roller damping structure in the present application to the storage box, the roller damping structure is located between the bottom of the box body and the bottom of the chamber. When heavy objects are assembled in the box body, even if the bottom of the box body is deformed, the roller will still abut against the bottom of the box body or the bottom of the chamber. The deformation of the bottom of the box body will not cause the damping to lose its function, that is, under the heavy pressure of the box body, the roller can still roll and play the role of damping. At the same time, the roller damping structure in the present application can also provide a support point for the box body to enhance the stiffness of the box body, while the existing ordinary damping structure cannot support the bottom of the box body. When the items placed in the box body are heavy, the phenomenon that the bottom of the box body and the bottom of the chamber are tightly stuck will occur.
[0013] Therefore, by applying the roller damping structure in the present application to the storage box, the load-bearing capacity of the box body is improved, and after the load-bearing of the box body is increased, the damping structure will not fail and can still work normally.
[0014] Preferably, the roller damping structure is improved, and an elastic member for pressing the roller against the external object (the external object is the object acting on the roller) is connected to the roller stand. The function of the elastic member is to make the roller closely adhere to the external object to ensure that the roller closely abuts against the external object and will not be suspended. At the same time, in the present application, the roller abuts against the external object not rigidly but elastically. During the rolling process of the roller on the external object, it can perform adaptive elastic swinging according to the smoothness of the surface of the external object, avoiding jamming between the roller and the external object and ensuring the smooth rolling of the roller.
[0015] Preferably, the roller damping structure is improved, and one end of the roller stand is a rotating end, and the roller stand can swing around the rotating end. Thus, by swinging the roller stand around the rotating end, the roller can perform adaptive swinging on the external object.
[0016] Preferably, the roller damping structure is improved. The other end of the roller frame is the force-receiving end, and the elastic member acts on the force-receiving end. Thus, the elastic member applies an elastic force to the force-receiving end, and the force-receiving end makes the roller frame have a force approaching the external object under the action of the elastic force of the elastic member, so that the roller is pressed against the external object.
[0017] Preferably, the roller damping structure is improved. The elastic member is a compression spring, and a limiting member is provided on the roller frame. One end of the compression spring is sleeved on the limiting member. Through the compression spring, pressure is applied to the roller frame, so that the roller is pressed tightly against the external object. The limiting member is used to fixedly limit the compression spring, so that the compression spring can be connected to the roller frame.
[0018] Preferably, the roller damping structure is improved. A rotating shaft is provided at the rotating end. Through the rotating shaft, the rotation of the rotating end is realized.
[0019] Preferably, the roller damping structure is improved. The roller frame includes a first roller frame and a second roller frame. The first roller frame and the second roller frame are detachably connected. The rotary damper and the roller are both located between the first roller frame and the second roller frame, and the first roller frame and the second roller frame clamp the rotary damper and the roller. Thus, the rotary damper and the roller are clamped by the first roller frame and the second roller frame, and the rotary damper and the roller are more firmly and stably located on the roller frame. The roller damping structure in this solution is assembled by the first roller frame, the second roller frame, the rotary damper and the roller, which is convenient for manufacturing and processing.
[0020] Preferably, the storage box is improved. A receiving groove is provided at the bottom of the box body or the bottom of the chamber, and the roller frame is located in the receiving groove. The receiving groove is used to receive the roller frame, and when setting the roller frame, the space occupied by the roller frame can be reduced. Description of the Drawings

[0029] The following is a further detailed description through specific implementation modes:
[0030] The reference numerals in the accompanying drawings of the specification include: box body 1, chamber 2, bottom of the chamber 3, receiving groove 4, limiting member 41, hole 42, roller damping structure 5, elastic member 51, first roller frame 52, second roller frame 53, roller 54, rotating shaft 55, rotary damper 56, shaft hole 57, clamping block 58, clamping groove 59, fixing column 60, rotating shaft 61, box body 6.
[0031] The embodiment is basically as shown in the attached Figures 1 - 8 figure.
[0032] This embodiment discloses a roller damping structure. As shown in combination with Figure 7 and Figure 8 , it includes a roller frame, a roller 54 and a rotary damper 56. The roller frame is used to support the roller 54 and the rotary damper 56. The roller frame in this embodiment includes a first roller frame 52 and a second roller frame 53. The first roller frame 52 and the second roller frame 53 can be buckled together, and the first roller frame 52 and the second roller frame 53 are detachably connected. In this embodiment, the detachable connection method is: one of the first roller frame 52 or the second roller frame 53 is provided with a clamping block 58, and the other structure is provided with a clamping groove 59. By clamping the clamping block 58 in the clamping groove 59, the detachable connection between the first roller frame 52 and the second roller frame 53 is realized. Of course, in other implementation modes, other detachable connection methods can also be adopted, such as fixed connection by screws or bolts. In this embodiment, the roller frame is divided into two parts, namely the first roller frame 52 and the second roller frame 53. Of course, in other implementation modes, the roller frame can also be assembled from more parts.
[0033] In this embodiment, a rotary damper 56 is fixedly installed on the first roller frame 52. The rotary damper 56 is existing, and its specific principle and structure will not be elaborated. As shown in combination with Figure 8As shown, two fixing lugs are integrally provided on the outer shell of the rotary damper 56. A column hole is provided on the fixing lug, and a fixing column 60 is provided on the first roller frame 52. The fixing column 60 is inserted into the column hole of the fixing lug, thereby realizing the positioning and fixing of the rotary damper 56 and the first roller frame 52. A protruding rotating shaft 61 is connected inside the rotary damper 56. In this embodiment, a roller 54 is rotatably connected to the second roller frame 53. Specifically, a rotating hole is provided on the second roller frame 53. A roller shaft is integrally fixed in the middle of the roller 54. The roller shaft is inserted into the rotating hole and can rotate in the rotating hole. A shaft hole 57 is provided on one side of the roller 54 facing the rotating shaft 61. By inserting the rotating shaft 61 into the shaft hole 57, the rotating shaft 61 and the shaft hole 57 are clamped (the clamping method is specifically that the shaft hole 57 is square, and the end of the rotating shaft 61 inserted into the shaft hole 57 is also square; in other embodiments, other connection methods can also be used, such as connection by pins, etc.), thereby realizing the coaxial connection of the rotating shaft 61 and the roller 54, and realizing that the roller 54 is coaxially connected to the rotary damper 56.
[0034] In this embodiment, an elastic member 51 for pressing the roller 54 against an external object (the external object is an object acting on the roller 54. In Figure 6 , the external object is the bottom of the box body 6) is connected to the first roller frame 52 or the second roller frame 53. One end of the first roller frame 52 or the second roller frame 53 is a rotating end, and a rotating shaft 55 is connected at the rotating end. The entire roller frame can swing around the rotating end. The other end of the first roller frame 52 or the second roller frame 53 is a stress end, and the elastic member 51 acts on the stress end. The elastic member 51 in this embodiment is a compression spring. A limiting member is provided on the first roller frame 52. The limiting member in this embodiment is a limiting column, and one end of the compression spring is sleeved on the limiting member on the first roller frame 52.
[0035] The first roller frame 52 and the second roller frame 53 in this embodiment are only marked and distinguished for the convenience of description. In fact, the names of the structures pointed to by the two can be interchanged, which will not affect the essential structure of the roller damping in this embodiment.
[0036] Combined with Figures 1 - 6 As shown, a storage box is disclosed in this embodiment, including a box body 1 and a box body 6. A chamber 2 is provided on the box body 1. Figure 2 The box body 6 in
[0037] is inserted into the chamber 2 and thus slides in the chamber 2. A roller damping structure 5 as described above is provided between the bottom of the box body 6 and the bottom of the chamber 2. Figure 3 and Figure 4As shown, the roller rack in this embodiment is installed at the bottom 3 of the chamber. A receiving groove 4 is provided at the bottom 3 of the chamber. The above-mentioned roller damping structure 5 is installed in the receiving groove 4. A hole 42 is provided in the receiving groove 4. The rotating shaft 55 is inserted into the hole 42, thereby realizing the rotation of the roller rack in the receiving groove 4. The roller 54 protrudes from the receiving groove 4. A limiting member 41 is also provided at the bottom of the receiving groove 4. The limiting member 41 is a limiting post. The bottom end of the compression spring is sleeved on the limiting member 41 in the receiving groove 4, and the top end of the compression spring is sleeved on the limiting member on the roller rack. After the box body 6 is inserted into the chamber 2, the bottom of the box body 6 abuts against the roller 54.
[0038] Thus, when the box body 6 is pulled out, the box body 6 moves in the chamber 2, and the roller rack approaches the bottom of the box body 6 under the action of the compression spring. As Figure 6 shown, the roller 54 presses on the bottom of the box body 6. When the box body 6 moves, the bottom of the box body 6 drives the roller 54 to rotate on the roller rack through friction. Since the roller 54 is connected to the rotary damper 56, the roller 54 rolls relatively stably and slowly, so that the box body 6 also slides relatively stably in the chamber 2. When a part of the box body 6 is pulled out of the chamber 2 and the roller 54 can be in a stable stationary state under the action of the rotary damper 56, the roller 54 will not rotate automatically, and at this time the box body 6 can also be in a stable stationary state.
[0039] In this embodiment, when heavy objects are assembled in the box body 6, even if the bottom of the box body 6 is slightly deformed, the roller rack will swing slightly around the rotating shaft 55, and the roller 54 will swing appropriately to adjust its position, but the roller 54 will still abut against the bottom of the box body 6 under the action of the compression spring and can roll normally. The deformation of the bottom of the box body 6 will not cause the damping to lose its effect, that is, under the heavy pressure of the box body 6, the roller 54 can still roll and play the role of damping. At the same time, the roller 54 damping in this application can also provide a support point for the box body 6 to enhance the stiffness of the box body 6. When the items placed in the box body 6 are heavy, there will be no phenomenon that the bottom of the box body 6 is deformed greatly and is tightly stuck to the bottom 3 of the chamber.
[0040] Of course, in other embodiments, the roller rack can also be installed (for the installation method, refer to the connection method between the roller rack and the bottom of the chamber) at the bottom of the box body 6. At this time, the roller 54 faces downward and the roller 54 abuts against the bottom 3 of the chamber. When the box body 6 moves, the box body 6 drives the roller rack to move together, and the roller 54 rolls on the bottom 3 of the chamber.
[0041] This embodiment also discloses an automobile, including the above-mentioned storage box.
[0042] The above are only the embodiments of the present utility model. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present utility model, several modifications and improvements can be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
