Through the sliding storage rack body on the frame body, users can easily and conveniently take and put items, thereby improving the convenience during use.

[0003] In the prior art, the outer frame and the frame of the pull-out storage rack are slidably matched through a slide rail assembly, and the slide rail assembly includes an outer slide rail, a middle slide rail, a ball slide rail and an inner slide rail. The outer slide rail is fixed to the outer frame, the middle slide rail is slidably matched with the outer frame, and the inner slide rail is arranged on the side of the outer frame. The ball slide rail is slidably matched with the middle slide rail and the inner slide rail, thereby realizing the back and forth movement of the frame.

[0004] However, the slide rail assembly in the above-mentioned prior art needs to use multi-layer slide rails, uses more parts, and the matching mode between the parts is relatively complicated, which is not conducive to improving space utilization. Summary of the invention

[0005] One of the purposes of the present invention is to provide a storage rack to solve the problem that the slide rail assembly between the rack body and the outer frame of the storage rack in the prior art uses many parts, the matching method between the parts is relatively complicated, and it is not conducive to improving space utilization; the second purpose is to provide a vehicle.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] A storage rack comprises: an outer frame, the outer frame defining a storage cavity, and a pull-out opening communicating with the storage cavity is formed at one end of the outer frame along a first direction; a frame body, the frame body being pullable in the storage cavity via the pull-out opening; a sliding auxiliary device, provided on at least one of the outer frame and the frame body, the sliding auxiliary device comprising: a sliding bracket and a ball bearing, the sliding bracket comprising a supporting portion having a plurality of surfaces corresponding to the frame body respectively, each of the supporting portions being provided with the ball bearing, and the outer frame and the frame body being slidably matched via the ball bearing.

[0008] According to the above technical means, a sliding auxiliary device is provided on at least one of the frame and the outer frame to achieve sliding cooperation between the frame and the outer frame, so that the frame can be pulled out through the pull-out opening, and a plurality of support parts are provided on the sliding bracket, and the plurality of support parts correspond to different surfaces of the outer frame or the frame, and a ball is provided on each support part. When the frame is pulled out, the ball rolls to reduce the sliding resistance between the outer frame and the frame. In this way, only one sliding bracket is provided and the ball is installed on the sliding bracket to achieve sliding cooperation between the frame and the outer frame. Compared with the prior art that mostly provides multiple layers of slide rails between the frame and the outer frame, the sliding auxiliary device of the present application requires fewer parts and can directly form a sliding cooperation with the outer frame or the frame through the ball to achieve the pulling out of the frame. The cooperation method is simpler, which is conducive to saving the production cost of the storage rack. At the same time, the sliding bracket occupies less space, which is conducive to improving the space utilization rate of the storage rack.

[0009] Furthermore, the sliding auxiliary device includes: a first auxiliary device, including a first sliding bracket and a first ball bearing, the first sliding bracket is fixedly arranged on the outer wall of the frame, and the first ball bearing is arranged on a side of the first sliding bracket facing the outer frame.

[0010] According to the above technical means, the inner wall of the outer frame can serve as the slide rail of the first ball, so that the sliding fit between the frame and the outer frame can be achieved. When the frame is pulled out, the first auxiliary device moves toward or away from the second auxiliary device with the frame, and the fit method is relatively simple.

[0011] Furthermore, a plurality of first support parts are formed on the first sliding bracket, and the plurality of first support parts are respectively located on both sides of the frame along the second direction and on one side along the third direction. Each of the first support parts is provided with a first rolling ring, and the first ball can be rotatably disposed in the first rolling ring and rollingly cooperate with the inner wall of the outer frame on that side.

[0012] According to the above technical means, it is helpful to ensure the stability of the first sliding bracket structure. At the same time, the first rolling ring can reduce the friction during sliding. When the frame slides relative to the outer frame, the first ball rolls freely in the first rolling ring, which can reduce friction and improve the efficiency and smoothness of sliding, which is helpful to make the frame pulling and pulling smoother.

[0013] Furthermore, the first sliding bracket further includes: a first bracket body, the first bracket body is located at one side of the bracket body along the first direction, and the plurality of first supporting parts are respectively connected to the first bracket body.

[0014] According to the above technical means, the first bracket body is provided to enhance the structural strength of the first sliding bracket, and the first bracket body is provided on one side of the bracket along the first direction to ensure that the bracket can slide relative to the outer frame along the first direction.

[0015] Furthermore, a weakened notch is provided at a connection between the first rolling ring and the first supporting portion.

[0016] According to the above technical means, when installing the first ball, the first ball is placed on the surface of the first rolling ring, and the first ball is pressed hard, the weakened notch opens, the diameter of the first rolling ring increases, and the first ball enters the first rolling ring. After the first ball enters, the pressure disappears, the weakened notch recovers, and the diameter of the first rolling ring decreases, thereby preventing the first ball from falling off. This is conducive to improving the assembly efficiency of the first ball.

[0017] Furthermore, the frame body is provided with a first notch at a corner portion of one end along the first direction, the frame body includes a first side wall along the third direction, and the first side wall has mounting flanges extending along the third direction formed on both side edges along the second direction, and the first side wall and the two mounting flanges are used for rolling cooperation with the first ball.

[0018] According to the above-mentioned technical means, after the first bracket body is fixed on the second side wall, a certain gap is left between the first side wall or the installation flange and the first support part, and the first ball is located between the first side wall or the installation flange and the first rolling ring on the first support part. In this way, the first side wall and the installation flange can play a certain limiting role, which can ensure that the first ball is always located in the first rolling ring, avoiding the first ball from falling off under the pressure of the inner wall of the outer frame, which is beneficial to improving the stability of the first auxiliary device structure.

[0019] Further, along the second direction, the outer surface of the first supporting portion does not exceed the outer surface of the first side wall, and the first rolling ball exceeds the outer surface of the first side wall.

[0020] According to the above technical means, the distance between the outer surface of the frame and the inner surface of the outer frame can be reduced, which is beneficial to further reduce the space occupied by the first auxiliary device and improve the space utilization rate in the accommodating cavity.

[0021] Furthermore, the sliding auxiliary device also includes: a second auxiliary device, which is spaced apart from the first auxiliary device along the first direction, the second auxiliary device includes a second sliding bracket and a second ball, the second sliding bracket is fixedly arranged on the outer frame, and the second ball is arranged on a side of the outer frame facing the second sliding bracket.

[0022] According to the above technical means, the outer wall of the frame can serve as the slide rail of the second ball, so as to achieve sliding cooperation between the frame and the outer frame. When the frame is pulled out, the second auxiliary device remains stationary, and the frame slides relative to the second auxiliary device. The cooperation method is relatively simple.

[0023] Furthermore, the frame and the outer frame each include a first end and a second end opposite to each other along a first direction, the first auxiliary device is disposed at the first end of the frame, and the second auxiliary device is disposed at the second end of the outer frame.

[0024] According to the above technical means, it can be ensured that the sliding distance of the frame is the length of the accommodating cavity along the first direction, and at the same time, it can play a role in limiting the frame, which is beneficial to prevent the frame from sliding out of the accommodating cavity and separating from the outer frame.

[0025] Furthermore, a plurality of second support parts are formed on the second sliding bracket, and the plurality of second support parts are respectively located on the two side cavity walls of the outer frame along the second direction and the one side cavity wall along the third direction. Each second support part is provided with a second rolling ring, and the second ball can be rotatably arranged in the second rolling ring and rollingly cooperate with the outer wall of the frame on that side.

[0026] According to the above technical means, the plurality of second support parts correspond to the outer walls of the frame in three different directions, which can further support the frame and improve the stability of the rack structure. When the frame slides relative to the second support part, the second ball rolls in the second rolling ring under the friction of the outer wall of the frame, which can further reduce the friction between the outer wall of the frame and the inner wall of the outer frame, which is conducive to making the pulling and pulling of the frame smoother and the sliding efficiency of the frame higher.

[0027] Furthermore, installation notches are respectively provided on the cavity walls on both sides of the outer frame along the second direction, and the two second support parts along the second direction are respectively engaged in the corresponding installation notches.

[0028] According to the above technical means, the surrounding side of the drawer opening of the outer frame can be kept flat, avoiding the second auxiliary device from protruding from the outer frame, affecting the appearance of the storage rack, and easily causing collisions that may cause the connection between the second auxiliary device and the outer frame to break.

[0029] Furthermore, along the second direction, the inner surface of the first support portion is not lower than the inner surface of the outer frame, and the second rolling ball protrudes from the inner surface of the outer frame.

[0030] According to the above technical means, the inner surface of the outer frame can be kept smooth, preventing the second auxiliary device from interfering with the sliding of the frame, which is beneficial to ensuring the smooth sliding of the frame. At the same time, it is beneficial to reduce the gap between the inner surface of the outer frame and the outer surface of the frame, thereby improving the space utilization rate in the accommodating cavity.

[0031] Furthermore, a clamping hole is provided on the cavity wall of the outer frame along the first direction, and a buckle is provided on the second supporting portion along the third direction, and the buckle is clamped in the clamping hole.

[0032] According to the above technical means, when installing the second auxiliary device, it is only necessary to push the second auxiliary device into the installation notch along the first direction so that the buckle is engaged with the hole on the outer frame. The operation is simple and convenient, which is conducive to improving the assembly efficiency of the shelf.

[0033] Furthermore, the second sliding bracket also includes a fixing portion, which is arranged side by side with one of the second supporting portions, the fixing portion is provided with a first fixing hole, the outer frame is provided with a second fixing hole, and the second sliding bracket and the outer frame are connected through the first fixing hole and the second fixing hole.

[0034] According to the above technical means, after the buckle is engaged with the hole, connecting structures such as bolts and screws are passed through the first fixing hole and the second fixing hole in sequence, thereby fixing the second sliding bracket and the outer frame together, which is beneficial to improving the stability of the connection between the second auxiliary device and the outer frame.

[0035] Furthermore, each of the supporting parts is provided with a plurality of the balls distributed at intervals.

[0036] According to the above technical means, it is helpful to enhance the support of the sliding auxiliary device, further reduce friction, and ensure that the frame can slide more smoothly.

DETAILED DESCRIPTION

[0061] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0062] As shown in the background technology, in the prior art, the outer frame and the frame of the pull-out storage rack are slidably matched by a slide rail assembly, and the slide rail assembly includes an outer slide rail, a middle slide rail, a ball slide rail and an inner slide rail. The outer slide rail is fixed to the outer frame, the middle slide rail is slidably matched with the outer frame, and the inner slide rail is arranged on the side of the outer frame. The ball slide rail is slidably matched with the middle slide rail and the inner slide rail, thereby realizing the back and forth movement of the frame. However, the above-mentioned slide rail assembly requires the use of multiple layers of slide rails, uses more parts, and the matching method between the parts is relatively complicated, which is not conducive to improving space utilization.

[0063] In view of the above technical problems, the embodiment of the present application provides a storage rack and a vehicle, wherein the storage rack includes an outer frame, a frame body and a sliding auxiliary device, a draw-out opening is formed at one end of the outer frame, and the frame body achieves sliding cooperation with the outer frame through the sliding auxiliary device, so that it can be drawn out through the draw-out opening and is arranged in a receiving cavity of the outer frame. The sliding auxiliary device includes a sliding bracket and a ball, the sliding bracket is fixed on one of the outer frame and the frame body, the ball is fixed on the support part of the sliding bracket and contacts the other, a plurality of support parts are arranged on the sliding bracket, and the plurality of support parts correspond to different surfaces of the outer frame or the frame body, and when the frame body is drawn out, the ball rolls to reduce the sliding resistance between the outer frame and the frame body. In this way, it is only necessary to set up a sliding bracket and install ball bearings on the sliding bracket to achieve the sliding fit between the frame and the outer frame. Compared with the prior art, in which multiple layers of slide rails are set between the frame and the outer frame, the sliding auxiliary device of the present application requires fewer parts and can directly form a sliding fit with the outer frame or the frame through the ball bearings to achieve the pulling and pulling of the frame. The fit method is simpler, which is beneficial to saving the production cost of the rack. At the same time, the sliding bracket occupies less space, which is beneficial to improving the space utilization rate of the rack.

[0064] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings:

[0065] It should be noted that the storage rack provided in the embodiment of the present application can be applied to various vehicles.

[0066] See also Figures 1 to 5 and Fig.15 As shown, the storage rack 100 of the embodiment of the present application includes: an outer frame 110, a frame body 120 and a sliding auxiliary device 130, the outer frame 110 defines a accommodating cavity 111, and a pull-out opening 112 connected to the accommodating cavity 111 is formed at one end of the outer frame 110 along a first direction; the frame body 120 is pullable in the accommodating cavity 111 via the pull-out opening 112. Figure 2 The X direction is the first direction, the Z direction is the second direction, and the Y direction is the third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0067] Among them, the frame body 120 can be set as a foldable structure. When the storage rack 100 is needed, the frame body 120 is pulled out and unfolded through the draw opening 112. The frame body 120 defines a storage space for the user to store items therein. When the storage rack 100 is not needed, the frame body 120 can be folded and pushed into the accommodation cavity 111 through the draw opening 112 to save the space occupied by the storage rack 100. Or the frame body 120 can be set as a fixed structure. When the frame body 120 is pulled out, items therein can be taken or put into it, and then the frame body 120 is pushed back into the accommodation cavity 111. The outer frame 110 covers the storage space inside the frame body 120 to prevent dust and the like from falling into the storage space to keep the items clean. Of course, the specific structure of the frame body 120 is not limited in the embodiments of the present application and can be reasonably selected according to the use scenario of the storage rack 100. For example, when the storage rack 100 needs to be set in a vehicle, since the vehicle space is relatively limited, the outer frame 110 can be fixed under the vehicle seat 10 or other positions, and the frame body 120 is set as a foldable structure. When the storage rack 100 is needed, the frame body 120 is pulled out and unfolded, and when not needed, the frame body 120 is folded and retracted to release the space in the cockpit.

[0068] In the embodiments of the present application, the sliding cooperation between the frame body 120 and the outer frame 110 is realized through the sliding auxiliary device 130. The sliding auxiliary device 130 is provided on at least one of the outer frame 110 and the frame body 120. The sliding auxiliary device 130 includes: a sliding bracket and balls. The sliding bracket includes a supporting portion having a plurality of surfaces corresponding to the frame body 120, and balls are provided on each supporting portion. The outer frame 110 and the frame body 120 are in sliding cooperation through the balls. The sliding bracket is provided on one of the outer frame 110 and the frame body 120. The balls on the sliding bracket can freely roll around their own centers on the supporting portion, and the balls are in contact with the surface of the other of the outer frame 110 and the frame body 120. Exemplarily, the sliding bracket is fixed on the frame body 120, and the plurality of supporting portions of the sliding bracket face the inner walls of different directions of the outer frame 110, and at least one ball is provided on each supporting portion. In this way, when the frame body 120 is pulled, the balls roll under the action of the friction force of the inner wall of the outer frame 110, so that the resistance of the frame body 120 sliding relative to the outer frame 110 can be reduced, thereby realizing the sliding cooperation between the frame body 120 and the outer frame 110.

[0069] Of course, the size of the sliding bracket, the number of ball bearings on each support portion, and the number of sliding auxiliary devices 130 are not limited in the embodiments of the present application, and can be freely selected according to the volume and weight of the frame 120. When the overall volume of the frame 120 is small and the weight is light, only two sliding brackets are provided on the opposite sides of the frame 120 along the third direction to meet the sliding needs of the frame 120. When the volume of the frame 120 and the outer frame 110 is large and the frame 120 is heavy, the sliding auxiliary device 130 can be provided on both the frame 120 and the outer frame 110, and the area of ​​the support portion can be increased, multiple ball bearings can be provided on one support portion, or multiple support portions can be provided to improve the support of the sliding auxiliary device 130 to avoid deformation caused by excessive weight of the frame 120, thereby ensuring that the frame 120 can be smoothly pulled out.

[0070] Therefore, in the storage rack 100 provided in the embodiment of the present application, the structure of the sliding auxiliary device 130 is relatively simple, and only a sliding bracket and a ball bearing are required to achieve sliding cooperation with the outer frame 110 or the frame body 120. Fewer parts are required and the cooperation method is simple, which is beneficial to saving the production cost of the storage rack 100. At the same time, the volume of the sliding bracket is small, so the sliding auxiliary device 130 occupies less space in the accommodating cavity 111. Compared with the use of multi-layer slide rails in the prior art, the storage rack 100 in the embodiment of the present application releases more storage space while ensuring the stability of the frame body 120 being pulled out, which is beneficial to improving the space utilization rate of the storage rack 100 or reducing the space occupied by the storage rack 100.

[0071] In some possible implementations, see Figures 1 to 6 As shown, the sliding auxiliary device 130 of the embodiment of the present application includes a first auxiliary device 131 and a second auxiliary device 132, the first auxiliary device 131 includes a first sliding bracket 1311 and a first ball 1312, the first sliding bracket 1311 is fixedly arranged on the outer wall of the frame 120, and the first ball 1312 is arranged on the side of the first sliding bracket 1311 facing the outer frame 110; the second auxiliary device 132 and the first auxiliary device 131 are spaced apart along the first direction, the second auxiliary device 132 includes a second sliding bracket 1321 and a second ball 1322, the second sliding bracket 1321 is fixedly arranged on the outer frame 110, and the second ball 1322 is arranged on the side of the outer frame 110 facing the second sliding bracket 1321.

[0072] It can be understood that the first auxiliary device 131 is fixed on the frame 120, the first ball 1312 contacts the inner wall of the outer frame 110, and the second auxiliary device 132 is fixed on the outer frame 110, and the second ball 1322 contacts the outer wall of the frame 120. At this time, the inner wall of the outer frame 110 can act as a slide rail for the first ball 1312, and the outer wall of the frame 120 can act as a slide rail for the second ball 1322, so that the sliding fit between the frame 120 and the outer frame 110 can be achieved. When the frame 120 is pulled out, the first auxiliary device 131 moves with the frame 120 toward or away from the second auxiliary device 132.

[0073] In addition, the first auxiliary device 131 and the second auxiliary device 132 are arranged at intervals. When the frame 120 is pulled out, the frame 120 is supported by the first auxiliary device 131, the second auxiliary device 132 and the hand of the user of the rack 100 in sequence along the first direction, thereby ensuring that the frame 120 is stable in the same plane, which is beneficial to ensuring that the frame 120 slides smoothly relative to the outer frame 110. At the same time, it can also avoid the first auxiliary device 131 and the second auxiliary device 132 from interfering with each other and affecting the sliding of the frame 120.

[0074] In some possible implementations, see Figure 1 , Figure 2 and Figure 3 As shown, the frame 120 and the outer frame 110 of the embodiment of the present application both include a first end and a second end opposite to each other along a first direction, the first auxiliary device 131 is disposed at the first end of the frame 120 , and the second auxiliary device 132 is disposed at the second end of the outer frame 110 .

[0075] In a specific implementation, the first end is the end away from the pull-out opening 112, and the second end is the end where the pull-out opening 112 is set. Since the first auxiliary device 131 and the second auxiliary device 132 are located on the same straight line along the first direction, when the first auxiliary device 131 slides with the frame 120 to contact the second auxiliary device 132, the second auxiliary device 132 will hinder the first auxiliary device 131 from sliding further. Therefore, the first auxiliary device 131 is set at the first end of the frame 120, and the second auxiliary device 132 is set at the second end of the outer frame 110. This can ensure that the sliding distance of the frame 120 is the length of the accommodating cavity 111 along the first direction, and at the same time can play a limiting role on the frame 120, which is beneficial to prevent the frame 120 from sliding out of the accommodating cavity 111 as a whole and separating from the outer frame 110.

[0076] In some possible implementations, see Figure 1 , Figure 2 , Figure 4 , Figure 7 and Fig.12As shown, a plurality of first support portions 1311a are formed on the first sliding bracket 1311 of the embodiment of the present application. The plurality of first support portions 1311a are respectively located on both sides of the frame body 120 along the second direction and on one side along the third direction. Each first support portion 1311a is provided with a first rolling ring 1311b. The first ball 1312 can be rotatably disposed in the first rolling ring 1311b and rollingly cooperates with the inner wall of the outer frame 110 on that side.

[0077] In some embodiments, the first rolling ring 1311b can be set to a ring structure with a diameter slightly smaller than the ball to prevent the first ball 1312 from falling out of the first rolling ring 1311b, which is beneficial to ensuring the stability of the first sliding bracket 1311 structure. At the same time, the first rolling ring 1311b can reduce friction during sliding. When the frame 120 slides relative to the outer frame 110, the first ball 1312 rolls freely in the first rolling ring 1311b to achieve rolling cooperation with the inner wall of the outer frame 110. Compared with the first ball 1312 sliding relative to the inner wall of the outer frame 110, the rolling cooperation can reduce friction, improve the efficiency and smoothness of sliding, and help make the frame 120 pull out smoother.

[0078] In addition, the multiple first support portions 1311a correspond to the inner walls of the outer frame 110 in three different directions, so that the first sliding bracket 1311 can form support points in multiple directions to ensure the stability of the frame 120, while reducing friction from all sides, which is conducive to further improving the sliding stability of the frame 120.

[0079] For further information, see Figure 1 , Figure 3 , Figures 5 to 8 and Fig.11 As shown, the second sliding bracket 1321 can form a structure matching the first sliding bracket 1311. A plurality of second support portions 1321a are formed on the second sliding bracket 1321 of the embodiment of the present application. The plurality of second support portions 1321a are respectively located on the two side cavity walls of the outer frame 110 along the second direction and one side cavity wall along the third direction. Each second support portion 1321a is provided with a second rolling ring 1321b. The second ball 1322 can be rotatably disposed in the second rolling ring 1321b and rollingly cooperate with the outer wall of the frame 120 on that side.

[0080] In this way, the plurality of second support portions 1321a also correspond to the outer walls of the frame 120 in three different directions, which can further support the frame 120, prevent the rack 100 from shaking during the sliding process, and help improve the stability of the structure of the rack 100. At the same time, the second rolling ring 1321b has a similar function to the first rolling ring 1311b. When the frame 120 slides relative to the second support portion 1321a, the second ball 1322 rolls in the second rolling ring 1321b under the friction of the outer wall of the frame 120, which can further reduce the friction between the outer wall of the frame 120 and the inner wall of the outer frame 110, which is conducive to making the pulling and pulling of the frame 120 smoother and the sliding efficiency of the frame 120 higher.

[0081] In some possible implementations, see Figure 1 , Figure 2 and Figure 4 As shown, the first sliding bracket 1311 of the embodiment of the present application further includes: a first bracket body 1311c, the first bracket body 1311c is located at one side of the bracket body 120 along the first direction, and a plurality of support parts are respectively connected to the first bracket body 1311c.

[0082] In a specific implementation, the first bracket body 1311c connects multiple support parts together. The first bracket body 1311c and the support parts can be connected by welding or the like, or can be integrally formed. The embodiment of the present application does not limit this. The provision of the first bracket body 1311c can enhance the structural strength of the first sliding bracket 1311. The first bracket body 1311c is disposed on one side of the frame 120 along the first direction to ensure that the frame 120 can slide relative to the outer frame 110 along the first direction.

[0083] In some possible implementations, see Figure 4 and Figure 5 As shown, a weakened notch 1311b' is provided at the connection between the first rolling ring 1311b and the first supporting portion 1311a in the embodiment of the present application.

[0084] It can be understood that, in order to ensure that the first ball 1312 does not fall out of the first rolling ring 1311b, the diameter of the first rolling ring 1311b can be set to be smaller than the diameter of the first ball 1312. However, this may make the assembly of the first ball 1312 more difficult. Therefore, a weakening notch 1311b' can be provided on the side of the first rolling ring 1311b. When installing the first ball 1312, place the first ball 1312 on the surface of the first rolling ring 1311b and press the first ball 1312 forcefully. The weakening notch 1311b' opens, the diameter of the first rolling ring 1311b becomes larger, the first ball 1312 enters the first rolling ring 1311b. After the first ball 1312 enters, the pressure disappears, the weakening notch 1311b' resumes its original state, and the diameter of the first rolling ring shrinks, thus preventing the first ball 1312 from falling off. In this way, it is beneficial to improve the assembly efficiency of the first ball 1312.

[0085] It should be noted that when setting the weakening notch 1311b', the size of the weakening notch 1311b' needs to be reasonably selected according to the sizes of the first rolling ring and the first ball 1312 to avoid the weakening notch 1311b' being too large and affecting the structural strength of the first auxiliary device 131. The specific shape and size of the weakening notch 1311b' are not limited in the embodiments of the present application.

[0086] Similarly, a similar weakening notch 1311b' can also be provided on the side of the second rolling ring 1321b for the assembly of the second ball 1322. The basic principle is the same as that of the first rolling ring and will not be elaborated here.

[0087] In some implementable ways, as shown in Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 and Fig. 9 the frame body 120 of the embodiments of the present application forms first notches 121 at the corners at one end along the first direction. The frame body 120 includes a first side wall 122 along the third direction. Installation flanges 1221 extending along the third direction are respectively formed on both side edges of the first side wall 122 along the second direction. The first side wall 122 and the two installation flanges 1221 are both used for rolling cooperation with the first ball 1312.

[0088] In some embodiments, a first notch 121 is formed at a corner of the first end of the frame 120, and a first side wall 122 along a third direction extends along the first direction. The frame 120 may also include a second side wall 123 extending along the third direction. The first notch 121 is formed at the connection between the first side wall 122 and the second side wall 123, and the mounting flange 1221 is folded toward the direction where the first notch 121 is located. In this way, the first side wall 122 and the two mounting flanges 1221 form a mounting surface of the first support portion 1311a in three directions, and the second side wall 123 forms a mounting surface of the first bracket body 1311c, so that the first auxiliary device 131 is stably fixed on the frame 120. The first support portion 1311a and the first side wall 122 and the mounting flange 1221, and the first bracket body 1311c and the second side wall 123 can be connected by welding or other methods, and the specific connection method is not limited in the embodiments of the present application.

[0089] In some embodiments, after the first bracket body 1311c is fixed on the second side wall 123, a certain gap is left between the first side wall 122 or the installation flange 1221 and the first support portion 1311a, and the first ball 1312 is located between the first side wall 122 or the installation flange 1221 and the first rolling ring 1311b on the first support portion 1311a. In this way, the first ball 1312 and the first side wall 122 or the installation flange 1221 achieve rolling cooperation and can roll freely in the first rolling ring 1311b to ensure the smooth sliding of the frame body 120. At the same time, the first side wall 122 and the installation flange 1221 can also play a certain limiting role, which can ensure that the first ball 1312 is always located in the first rolling ring 1311b, avoiding the first ball 1312 from falling off under the pressure of the inner wall of the outer frame 110, which is beneficial to improving the stability of the structure of the first auxiliary device 131.

[0090] Furthermore, since there is a certain gap between the first side wall 122 and the installation flange 1221 and the first support portion 1311a, when the frame 120 and the first auxiliary device 131 are jointly loaded into the accommodating cavity 111, the first support portion 1311a still has a certain space to move, which can ensure that the first ball 1312a is pressed against the inner wall of the outer frame 110, while reducing the impact of production errors on the installation of the first auxiliary device 131. Among them, the size and shape of the installation flange 1221 and the first notch 121 are not limited in the embodiment of the present application, and can be reasonably selected according to the number and size of the first support portion 1311a.

[0091] Similarly, the matching relationship between the second supporting portion 1321a and the second ball 1322 on the second auxiliary device 132 and the inner wall of the outer frame 110 is similar to that of the first auxiliary device 131, and will not be described in detail here.

[0092] In some possible implementations, see Figure 1 , Figure 2 , Figure 4 , Figure 7 and Fig. 9 As shown, in the storage rack 100 of the embodiment of the present application, along the second direction, the outer surface of the first support portion 1311 a does not exceed the outer surface of the first side wall 122 , and the first ball bearing 1312 extends beyond the outer surface of the first side wall 122 .

[0093] In this way, the first sliding bracket 1311 is embedded in the frame body 120 through the first notch 121, and only the first ball 1312 partially protrudes from the outer surface of the first sliding bracket 1311, which can reduce the distance between the outer surface of the frame body 120 and the inner surface of the outer frame 110, which is beneficial to further reduce the space occupied by the first auxiliary device 131 and improve the space utilization in the accommodating cavity 111.

[0094] In some possible implementations, see Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Fig.10 As shown, the outer frame 110 of the embodiment of the present application is provided with installation notches 113 on both side walls along the second direction, and the two second support portions 1321 a along the second direction are respectively engaged in the corresponding installation notches 113 .

[0095] In a specific implementation, an installation notch 113 is provided at the second end of the outer frame 110, and the second support portion 1321a of the second auxiliary device 132 is engaged in the installation notch 113, so that the surrounding side of the pull-out opening 112 of the outer frame 110 can be kept flat, thereby preventing the second auxiliary device 132 from protruding out of the outer frame 110, affecting the appearance of the storage rack 100, and easily causing a collision that may cause the connection between the second auxiliary device 132 and the outer frame 110 to break.

[0096] In some possible implementations, see Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Fig.10 As shown, in the storage rack 100 of the embodiment of the present application, along the second direction, the inner surface of the first support portion 1321 a is not lower than the inner surface of the outer frame 110 , and the second rolling ball 1322 protrudes from the inner surface of the outer frame 110 .

[0097] It can be understood that the first support portion 1321a is embedded in the outer frame 110 through the installation notch 113, so that only the second ball 1322 portion of the second auxiliary device 132 protrudes from the inner surface of the outer frame 110. This can keep the inner surface of the outer frame 110 smooth, avoid the second auxiliary device 132 interfering with the sliding of the frame 120, and help to ensure the smooth sliding of the frame 120. At the same time, it is helpful to reduce the gap between the inner surface of the outer frame 110 and the outer surface of the frame 120, thereby improving the space utilization rate in the accommodating cavity 111.

[0098] In some possible implementations, see Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Fig.10 As shown, the outer frame 110 of the embodiment of the present application is provided with a locking hole 114 on the cavity wall along the second direction, and a buckle 1321a1 is provided on the second support portion 1321a along the third direction, and the buckle 1321a1 is locked in the locking hole 114.

[0099] In some embodiments, the second auxiliary device 132 is fixed to the outer frame 110 by the buckle 1321a1. When installing the second auxiliary device 132, it is only necessary to push the second auxiliary device 132 into the installation notch 113 along the first direction so that the buckle 1321a1 is engaged with the clamping hole 114 on the outer frame 110. The operation is simple and convenient, which is conducive to improving the assembly efficiency of the storage rack 100.

[0100] In some possible implementations, see Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Fig.10 As shown, the second sliding bracket 1321 of the embodiment of the present application also includes a fixing portion 1321c, which is arranged side by side with one of the second supporting portions 1321a, and a first fixing hole 1321c' is provided on the fixing portion 1321c, and a second fixing hole 115 is provided on the outer frame 110, and the second sliding bracket 1321 and the outer frame 110 are connected through the first fixing hole 1321c' and the second fixing hole 115.

[0101] In a specific implementation, after the buckle 1321a1 is engaged with the locking hole 114, in order to improve the stability of the connection between the second auxiliary device 132 and the outer frame 110, a fixing portion 1321c is also required to be provided, and a connecting structure such as bolts and screws is passed through the first fixing hole 1321c' and the second fixing hole 115 in sequence, so as to fix the second sliding bracket 1321 and the outer frame 110 together.

[0102] In addition, in order to further improve the stability of the second auxiliary device 132, a limiting protrusion 1321d can be further provided on the second supporting portion 1321a, and a gap is left between the limiting protrusion 1321d and the fixing portion 1321c, the gap forming a limiting groove 1321d' extending in the first direction, and a limiting flange 116 is provided on the cavity wall connecting the outer frame 110 and the fixing portion 1321c. When the second sliding bracket 1321 is pushed into the installation notch 113, the limiting flange 116 and the limiting groove 1321d' are limitedly matched, which is beneficial to ensuring the stability of the connection between the second auxiliary device 132 and the outer frame 110 and avoiding displacement of the second auxiliary device 132.

[0103] In some possible implementations, see Figure 1 , Fig.13 and Fig.14 As shown, each support portion of the embodiment of the present application is provided with a plurality of balls distributed at intervals.

[0104] It is understandable that when the frame 120 is large in size and weight, the sliding auxiliary device 130 needs to provide a greater supporting force to the frame 120 to ensure the smooth sliding of the frame 120. At the same time, when the frame 120 is heavier, the friction between the frame 120 and the outer frame 110 is greater, so more balls are needed to reduce the friction. Therefore, multiple balls are provided on each supporting part of the embodiment of the present application to ensure that the frame 120 can slide more smoothly.

[0105] Exemplarily, when the storage rack 100 is actually assembled, the following steps can be performed: first, the first ball 1312 is inserted into the first rolling ring 1311b, and then the first bracket body 1311c of the first auxiliary device 131 is welded to the second side wall 123. Thereafter, the first auxiliary device 130 and the frame 120 are put into the accommodating cavity 111 together, and then the second auxiliary device 132 is installed into the outer frame through the installation notch 113, and the buckle 1321a1 is engaged with the clamping hole 114. The connecting structure passes through the first fixing hole 1321c' and the second fixing hole 115 in sequence, so as to fix the second sliding bracket 1321 and the outer frame 110 together, thereby completing the assembly of the storage rack 100. After the installation is completed, under the restriction of the second auxiliary device 132, the frame 120 will not be able to completely slide out of the accommodating cavity 111, thereby avoiding the falling off of the frame 120 and ensuring the stability of the storage rack 100.

[0106] See also Figure 1 and Fig.15 As shown, an embodiment of the present application further provides a vehicle, comprising: any one of the above-mentioned storage racks 100 .

[0107] The structure and working principle of the storage rack 100 are described in detail in the above embodiments, and will not be described in detail here.

[0108] In the embodiments of the present application, the storage rack 100 can be arranged at the front row armrest box of the vehicle, or can be arranged under the middle seat 10 at the rear row of the vehicle. When there is no passenger on the middle seat 10, the rack body 120 can be pulled out to place items. When a passenger needs to sit on the middle seat 10, the rack body 120 is pushed back to leave space for the passenger's feet. The embodiments of the present application do not limit the specific position of the storage rack 100.

[0109] In summary, for the storage rack 100 provided in the embodiments of the present application, the outer frame 110 and the rack body 120 are slidably matched through the sliding auxiliary device 130. The sliding auxiliary device 130 includes a first auxiliary device 131 and a second auxiliary device 132. The first auxiliary device 131 is installed at the first end of the rack body 120, and the second auxiliary device 132 is installed at the second end of the outer frame 110. The first rolling balls 1312 on the first auxiliary device 131 are in contact with the inner wall of the outer frame 110, and the second rolling balls 1322 on the second auxiliary device 132 are in contact with the outer wall of the rack body 120. When the rack body 120 is pulled or pushed, the first auxiliary device 131 moves toward or away from the second auxiliary device 132 along with the rack body 120, and both the first rolling balls 1312 and the second rolling balls 1322 roll, thereby reducing the friction between the rack body 120 and the outer frame 110 and ensuring that the rack body 120 can slide smoothly. Therefore, compared with the prior art in which the rack body 120 and the outer frame 110 are slidably matched through multiple sliding rails, the sliding auxiliary device 130 in the embodiments of the present application has a simpler structure and occupies less space, which is beneficial to releasing the storage space in the storage rack 100 and improving the space utilization rate of the storage rack 100.
