[0036] Please refer to Figures 1 to 5 A knee guard storage box structure is provided by the utility model, which comprises a knee guard body 100 and a storage box body 300.

[0037] The inner side of the knee guard body 100 is provided with an assembly chamber 200, the assembly chamber 200 is provided with a port at the end facing the driver's cabin, and the bottom of the assembly chamber 200 is provided with a hinged shaft 210; the upper end of the storage box body 300 is provided with an open end, and the lower end of the storage box body 300 is provided with a mounting sleeve 310, the mounting sleeve 310 is rotatably sleeved on the hinged shaft 210, one end of the outer side of the rotating sleeve is provided with a damping convex part, and the end of the damping convex part abuts against the inner side wall of the assembly chamber 200, so that damping force is formed when the storage box body 300 is turned out from the port.

[0038] Compared with the prior art, the knee guard storage box structure comprises a knee guard body 100 and a storage box body 300, and the two parts are matched with each other to form a practical part with the functions of protection and storage. The assembly chamber 200 is a key installation space of the entire storage box structure, provides a containing area for the installation and subsequent movement of the storage box body 300, and is provided with a port at the end facing the driver's cabin, so that the storage box body 300 can be turned out or turned in, and the driver and passenger can conveniently operate and use. The open end arranged at the upper end of the storage box body 300 facilitates the driver and passenger to place or take out the articles in the storage box, provides an additional storage space in the vehicle, and improves the practicability and convenience of the space in the vehicle. The mounting sleeve 310 is rotatably sleeved on the hinged shaft 210, the rotatable connection between the storage box body 300 and the knee guard body 100 is realized, the smoothness of the relative movement between the two parts is ensured, and the rotation track of the storage box is limited, so that the storage box can only be rotated around the hinged shaft 210. When the storage box body 300 is turned out from the port, the end of the damping convex part abuts against the inner side wall of the assembly chamber 200, and due to the contact and friction between the two parts, damping force is formed, the storage box body 300 can be prevented from being quickly ejected due to inertia or external force interference during the turning-out process, the turning-out action of the storage box is more stable and gentle, the problem that the storage box collides with the knee guard and causes abnormal noise is avoided, and the problem that the storage box accidentally bumps the knee of the driver and passenger is overcome.

[0039] In addition, when the storage box body 300 needs to be returned for storage after use, the damping force can also slowly return it to its original position, preventing loud noises from rapid closing and improving the overall operation process and user experience. This knee pad storage box structure ingeniously combines knee pads with storage functions. Through reasonable structural design, especially the rotating structure with damping force, it not only facilitates the use of the storage box by the driver and passenger, but also improves the comfort and stability during use, providing an effective solution for optimizing the use of vehicle space.

[0040] Please refer to Figure 5 The lower end of the mounting sleeve 310 is provided with a gap 312 for the hinge shaft 210. The presence of the gap 312 allows the hinge shaft 210 to pass through the gap 312 and enter the mounting sleeve 310 when the storage box body 300 is installed on the pad body 100, thereby achieving accurate and convenient connection between the two. Without such a gap, it may be difficult to completely install the mounting sleeve 310 on the hinge shaft 210, such as the need for more complex assembly operations, or even the inability to successfully complete the installation. The gap 312 provides the necessary space for the installation process, making the installation process smoother and more efficient.

[0041] Specifically, the number of mounting sleeves 310 and hinge shafts 210 is two, and the two mounting sleeves 310 are integrally formed on the left and right sides of the lower end of the storage box body 300. The two hinge shafts 210 are arranged on the left and right sides of the bottom of the assembly chamber 200, and the hinge shafts 210 are arranged in the mounting sleeves 310 through the horizontal arrangement of the frame. Strengthen the connection between the storage box body 300 and the pad body 100, so that the storage box can be stably installed on the pad body 100 even in complex road conditions such as bumps and vibrations during vehicle operation, and will not easily loosen or shift, thereby reliably providing storage functions for the driver and passenger and ensuring the safety of the items stored therein.

[0042] Specifically, the damping protrusion includes multiple damping bosses 311, which are circumferentially arranged at one end of the outer side of the rotating sleeve. When the storage box body 300 rotates around the hinge shaft 210, regardless of the angle of rotation, the multiple damping bosses 311 can exert the same damping effect. The circumferential distribution achieves full coverage, avoiding the situation where excessive rotation and lack of damping force control occur in certain specific rotation positions due to the lack of local damping structure, thereby ensuring the consistency and stability of the damping effect throughout the rotation process. The damping boss 311 has an arcuate end that abuts against the inner wall of the assembly chamber 200, and the arcuate end can better fit the inner wall of the assembly chamber 200. On the one hand, compared with other shapes such as straight lines, the structure of the arc-shaped end has a relatively more stable contact area during contact and relative sliding with the inner wall, and there will be no problem of excessive instantaneous contact area changes due to factors such as sharp corners, which affects the uniformity of the damping force; on the other hand, when the arc-shaped end interacts with the inner wall of the assembly chamber 200, the friction force between the two can be distributed more evenly and smoothly, further improving the stability and predictability of the damping effect, making the rotation process of the storage box body 300 more stable and comfortable.

[0043] See also Figure 3 and Figure 4 The outer side of the open end of the storage box body 300 is provided with an upwardly extending end plate 320, and the guard plate body 100 is provided with an inwardly concave retaining groove 110, which is located above the end of the assembly chamber 200. When the storage box body 300 is closed, the end plate 320 is located within the retaining groove 110, and the outer side of the storage box body 300 is flush with the outer side of the guard plate body 100. When the storage box body 300 is in the closed state, the end plate 320 is precisely located within the retaining groove 110. This fit ensures that the storage box body 300 is precisely fixed in the storage position, preventing the storage box from loosening or shifting due to bumps and vibrations during driving, and greatly enhancing the stability of the storage box body 300 in the stored state. At the same time, the constraint of the limit groove 110 on the end plate 320 also limits the unnecessary shaking of the storage box body 300 in other directions, ensuring that it always remains in the correct storage position, and protecting the compactness and integrity of the overall structure of the knee guard. In addition, when the storage box body 300 is in the closed state, the outer side of the storage box body 300 can remain flush with the outer side of the guard body 100, achieving overall unity and beauty from a visual perspective, making the guard body 100 and the storage box body 300 appear to be a complete integral component. The existence of the storage box body 300 does not destroy the original appearance of the guard body 100, and it is more harmonious and integrated with the overall interior style of the vehicle, enhancing the sense of refinement and quality of the interior space.

[0044] In addition, the outer side of the storage box body 300 is integrally formed with a concave knob 360, which is located at the upper region of the storage box body 300 and below the end plate 320, facilitating the driver to open the storage box body by using the knob 360.

[0045] Preferably, a spring buffer 111 is arranged between the end plate 320 and the limiting groove 110, and the spring buffer 111 includes two hollow rubber plugs, which can be fixed on the left and right sides of the end plate 320 or the left and right sides of the groove bottom of the limiting groove 110. When the storage box body 300 is stored in the closed state, and the end plate 320 gradually enters the limiting groove 110, the rubber plugs will be deformed by being pressed due to the presence of the spring buffer 111, so that the impact force is effectively absorbed and buffered, making the storage action more stable and quiet, avoiding the adverse effects caused by hard impact, and prolonging the service life of the components. In addition, during the driving of the vehicle, due to bumps, vibrations and other reasons, the storage box body 300 may be slightly displaced in the storage position, causing repeated extrusion and friction between the end plate 320 and the limiting groove 110. At this time, the spring buffer 111 can continuously play a role, and relieve the repeated force by its elastic deformation, protect the surface of the end plate 320 and the limiting groove 110 from being damaged, maintain the good cooperation between them, and ensure the stability of the storage box in the storage state and the integrity of the overall structure.

[0046] Please refer to Figures 2 to 6 , the left and right sides of the assembly chamber 200 are respectively provided with metal springs 220, the metal springs 220 have elastic protrusions 221 towards the side of the storage box body 300, and the two sides of the storage box body 300 are respectively provided with limiting blocks 330, the limiting blocks 330 are clamped on the inner side of the elastic protrusions 221, for limiting the storage box body 300 in the closed state.

[0047] The metal elastic sheet 220 is located outside the side wall of the assembly chamber 200, and the side wall of the assembly chamber 200 is correspondingly provided with a strip-shaped slot. The elastic protrusion 221 can pass through the same side strip-shaped slot from outside to inside. One end of the metal elastic sheet 220 is provided with a mounting plate 222, and the mounting plate 222 is fixed on the back of the backboard body 100 by screws. The end of the mounting plate 222 is also provided with a positioning hole, and the back of the backboard body 100 is correspondingly provided with a positioning block. The positioning hole is inserted into the positioning block, so that the mounting plate 222 can be positioned, and the reserved hole on the mounting plate 222 is aligned with the threaded hole on the back of the knee guard, thereby facilitating the accurate connection of the subsequent screws. The other end of the metal elastic sheet 220 is provided with a clamping plate 223, and the end of the clamping plate 223 is bent outward and clamped in the connecting hole at the inner end of the same side strip-shaped hole. The mounting plate 222 and the backboard body 100 are installed, and the clamping plate 223 and the assembly chamber 200 are installed, so that the metal elastic sheet 220 remains stable, and the elastic protrusion 221 of the metal elastic sheet 220 can protrude out of the strip-shaped hole.

[0048] When the storage box body 300 is opened by rotating, the limiting block 330 presses the elastic protrusion 221 until the limiting block 330 passes the elastic protrusion 221. The storage box body 300 will not be suddenly opened, and the elastic protrusion 221 plays a role in delaying the opening of the storage box body 300. When the storage box body 300 is rotated to the closed state, the inner inclined surface of the elastic protrusion 221 abuts against the limiting block 330, which can limit the rotation closing angle of the storage box body 300. Meanwhile, the elastic protrusion 221 can also form an elastic buffer for the limiting block 330, thereby reducing the hard impact of the storage box body 300.

[0049] Please refer to Figure 4 The left and right sides of the assembly chamber 200 are respectively provided with an arc-shaped sliding groove 230 coaxial with the hinge shaft 210, and the left and right sides of the storage box body 300 are respectively provided with a limiting block 340. The limiting block 340 penetrates into the corresponding arc-shaped sliding groove 230, and the limiting block 340 rotates with the storage box body 300 to the end of the arc-shaped sliding groove 230, so as to limit the rotation angle of the storage box body 300 when opening and closing. When the storage box body 300 is rotated outward, that is, during the opening process, the limiting block 340 will move along the arc-shaped sliding groove 230 with the rotation of the storage box, until it reaches the end of the arc-shaped sliding groove 230. At this time, the limiting block 340 cannot continue to move, thereby limiting the continuous rotation of the storage box outward, and determining the maximum rotation angle of the opening of the storage box. Similarly, when the storage box body 300 is rotated inward for closing operation, the limiting block 340 will also move reversely along the arc-shaped sliding groove 230, and when it reaches the other end of the arc-shaped sliding groove 230, it will limit the further rotation of the storage box inward, and determine the accurate angle when closing.

[0050] Through the cooperation of the stop block 340 and the arc-shaped sliding groove 230, the interference and collision of the storage box body 300 with the surrounding components due to the excessively large turning-out angle can be avoided, and the risk of damage to the storage box body 300 due to unreasonable force on the structure of the storage box body 300 itself caused by excessive turning-out can also be prevented.

[0051] Please refer to Figure 4 The left and right sides of the storage box body 300 are respectively provided with limiting ribs 350, and the limiting ribs 350 on the same side are distributed from top to bottom. When various items need to be carried by the storage box, the items placed therein will generate a certain pressure on the side wall of the storage box. The limiting ribs 350 enhance the anti-deformation ability of the side wall, so that the side wall can better withstand these pressures and avoid deformation such as bulging outward and concave. In addition, when the storage box body 300 is in a closed state, the existence of the limiting ribs 350 can also make the gap on both sides of the storage box body 300 uniform, reduce the tendency of the storage box body 300 to shake left and right, and improve the aesthetic appearance.

[0052] Please refer to Figure 2 and Figure 7 One end of the inside of the assembly chamber 200 is provided with a cross beam 240, and the two ends of the cross beam 240 are respectively inserted and connected with the left and right sides of the assembly chamber 200. The rear side of the assembly chamber 200 is designed as an open structure, and the rear upper part of the two side walls of the assembly chamber 200 is respectively provided with a clamping port. One end of the cross beam 240 is provided with an insertion plate 241, and the insertion plate 241 is inserted into the clamping port on one side from front to back. The outer side of the insertion plate 241 is provided with an elastic clamping block 242, and the elastic clamping block 242 is deformed along with the insertion plate 241 through the clamping port, thereby preventing the insertion plate 241 from being reversely pulled out of the clamping port. The other end of the cross beam 240 is provided with a V-shaped clamping plate 243, and the tip of the V-shaped clamping plate 243 is inserted into the clamping port on the other side from back to front. As the V-shaped clamping plate 243 is gradually inserted into the clamping port, the opening of the V-shaped clamping plate 243 gradually decreases. The outer side of the V-shaped clamping plate 243 is provided with a clamping table 244, and when the clamping table 244 passes through the corresponding clamping port, the V-shaped clamping plate 243 rebounds to form a spring force to both sides. At the same time, the clamping table 244 can also block the V-shaped clamping plate 243 from being reversely pulled out of the clamping port. When disassembling the cross beam 240, the end of the V-shaped clamping plate 243 provided with the clamping table 244 is pressed, and the angle of the V-shaped clamping plate 243 is further reduced until the clamping table 244 can be pulled out of the corresponding clamping port. Then, the elastic clamping block 242 of the insertion plate 241 on the other side is pressed, and the elastic clamping block 242 is pulled out of the corresponding clamping port along with the insertion plate 241, thereby completing the quick disassembly of the cross beam 240. The cross beam 240 can be detachably installed at the rear side of the assembly chamber 200, which can improve the structural strength of the assembly chamber 200 itself, and also facilitate the maintenance of the assembly chamber 200.

[0053] Based on the same inventive concept, the utility model still provides a kind of vehicle, because the knee guard storage box structure of above has been used, therefore possess the same beneficial effect with the knee guard storage box structure of above, here no longer repeat.

[0054] The above merely describes preferred embodiments of the utility model, and is not intended to limit the utility model, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
