Buffer structure and storage box

Abstract

This application discloses a buffer structure and a storage box. The buffer structure includes: a first connecting part, a second connecting part, an elastic element, a first damping part, and a second damping part. The elastic element drives the second connecting part to rotate relative to the first connecting part in a first direction, thereby causing the cover of the storage box to rotate relative to the box body to open the box body. It can also drive the second damping part to rotate relative to the first damping part. During this process, the second inclined surface on the second damping part can slide and engage with the first inclined surface on the first damping part. Thus, as the second connecting part continues to rotate, the contact between the first damping part and the second damping part gradually tightens, and the friction between the first damping part and the second damping part increases, thereby hindering the process of the second connecting part rotating relative to the first connecting part in the first direction, that is, damping the process of the cover opening relative to the box body. The damping effect is achieved by setting the first inclined surface and the second inclined surface to slide and engage. The structure is simple and the production cost is low.

Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a buffer structure and a storage box. Background Technology

[0002] Cars are equipped with storage compartments. The cover of the storage compartment can swing relative to the compartment body to open and close the compartment. An elastic element is also installed to drive the cover to open automatically. In order to make the opening process of the storage compartment cover slow down, a damper is added in related technologies. The damper connects the cover and the compartment body to provide resistance when the cover opens automatically, so that the cover opens slowly. However, the installation of the damper takes up space and the production cost is relatively high. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a buffer structure that can achieve a damping effect through an inclined plane, has a small structural footprint, and low production cost.

[0004] This application also proposes a storage box having the above-mentioned buffer structure.

[0005] The buffer structure according to a first aspect embodiment of the present application includes: a first connecting portion, a second connecting portion, an elastic member, a first damping portion, and a second damping portion.

[0006] The second connecting part is rotatably connected to the first connecting part; one of the first connecting part and the second connecting part is used to connect to the cover of the storage box, and the other is used to connect to the body of the storage box. An elastic element is connected to the first connecting portion and the second connecting portion, driving the second connecting portion to rotate relative to the first connecting portion about a first direction; A first damping part is connected to the first connecting part, and the first damping part is provided with a first inclined surface; The second damping part is connected to the second connecting part, and the second damping part is located on one side of the first damping part. The second damping part is provided with a second inclined surface, which can slide and cooperate with the first inclined surface. The first damping part and the second damping part are disposed between the first connecting part and the first connecting part. When the second connecting part rotates relative to the first connecting part about a first direction, the first inclined surface and the second inclined surface slide together to prevent the second connecting part from rotating about the first direction.

[0007] The buffer structure according to the first aspect of this application has at least the following beneficial effects: the elastic member drives the second connecting part to rotate relative to the first connecting part about a first direction, thereby causing the cover of the storage box to rotate relative to the box body and open the box body, and can also cause the second damping part to rotate relative to the first damping part. During this process, the second inclined surface on the second damping part can slide and engage with the first inclined surface on the first damping part. The second damping part slides from a low point to a high point on the first inclined surface, and the first damping part slides from a low point to a high point on the second inclined surface. Thus, as the second connecting part continues to rotate, the contact between the first damping part and the second damping part gradually tightens, and the friction between the first damping part and the second damping part increases, thereby hindering the process of the second connecting part rotating relative to the first connecting part about a first direction, that is, damping the process of the cover opening relative to the box body. The damping effect is achieved by setting the first inclined surface and the second inclined surface to slide and engage, which is simple in structure and has low production cost. Furthermore, the first damping part and the second damping part are disposed between the first connecting part and the second connecting part, which can reduce the space occupied by the first damping part and the second damping part.

The pressure block abuts against the side of the third connecting plate opposite to the second connecting plate. The other end of the rotating shaft extends out of the side of the first connecting plate opposite to the second connecting plate.

[0026] Reference Figure 1 , Figure 3 and Figure 4 The buffer structure according to the first aspect of this application includes: a first connecting part 100, a second connecting part 200, an elastic member 300, a first damping part 400, and a second damping part 500.

[0027] The second connecting part 200 is rotatably connected to the first connecting part 100; one of the first connecting part 100 and the second connecting part 200 is used to connect to the cover of the storage box, and the other is used to connect to the body of the storage box. The elastic element 300 is connected to the first connecting part 100 and the second connecting part 200, and drives the second connecting part 200 to rotate relative to the first connecting part 100 about a first direction; The first damping part 400 is connected to the first connecting part 100, and the first damping part 400 is provided with a first inclined surface 420; The second damping part 500 is connected to the second connecting part 200, and the second damping part 500 is located on one side of the first damping part 400. The second damping part 500 is provided with a second inclined surface 520, which can slide and cooperate with the first inclined surface 420. The first damping part 400 and the second damping part 500 are disposed between the first connecting part 100 and the first connecting part 100. When the second connecting part 200 rotates relative to the first connecting part 100 around the first direction, the first inclined surface 420 and the second inclined surface 520 slide together to prevent the second connecting part 200 from rotating around the first direction.

[0028] Understandably, the elastic element 300 drives the second connecting part 200 to rotate relative to the first connecting part 100 around a first direction, thereby causing the lid of the storage box to rotate relative to the box body and open the box body. It also drives the second damping part 500 to rotate relative to the first damping part 400. During this process, the second inclined surface 520 on the second damping part 500 can slide into contact with the first inclined surface 420 on the first damping part 400. The second damping part 500 slides from a lower position to a higher position on the first inclined surface 420, that is, from the side of the first inclined surface 420 away from the second connecting part 200 to the side of the first inclined surface 420 closer to the second connecting part 200. Correspondingly, the first damping part 400 slides from a lower position to a higher position on the second inclined surface 520. The damping part 400 slides from the side of the second inclined surface 520 away from the first connecting part 100 to the side of the second inclined surface 520 closer to the first connecting part 100. As the second connecting part 200 continues to rotate, the contact between the first damping part 400 and the second damping part 500 gradually tightens, increasing the friction between them. This hinders the rotation of the second connecting part 200 relative to the first connecting part 100 in the first direction. In other words, the sliding contact between the first inclined surface 420 on the first damping part 400 and the first inclined surface 420 on the second damping part 500 provides a damping effect when the cover plate opens relative to the housing. The structure is simple and the production cost is low. Furthermore, the placement of the first damping part 400 and the second damping part 500 between the first connecting part 100 and the second connecting part 200 reduces the space occupied by the first damping part 400 and the second damping part 500.

[0029] In this embodiment, the second connecting part 200 is fixedly connected to the cover plate, and the first connecting part 100 is fixedly connected to the box body. In some other embodiments, the first connecting part 100 may be fixedly connected to the cover plate, and the second connecting part 200 may be fixedly connected to the box body.

[0030] Reference Figure 3 and Figure 4 According to some embodiments of this application, the first damping part 400 is further provided with a first plane 410, which is connected to the side of the first inclined surface 420 near the second damping part 500. The second damping part 500 is further provided with a second plane 510, which is connected to the side of the second inclined surface 520 near the first damping part 400. The first plane 410 and the second plane 510 are in sliding engagement.

[0031] It is understandable that during the rotation of the second connecting part 200 relative to the first connecting part 100 in the first direction, after the second damping part 500 slides from the first inclined plane 420 to the highest point, that is, after the first damping part 400 slides from the second inclined plane 520 to the highest point, the second plane 510 of the second damping part 500 can abut against the first plane 410 of the first damping part 400. When the second connecting part 200 continues to rotate relative to the first connecting part 100 in the first direction, the second plane 510 slides relative to the first plane 410, so as not to further increase the friction between the second damping part 500 and the first damping part 400, that is, not to further increase the resistance to the relative rotation between the second connecting part 200 and the first connecting part 100, so as to ensure smooth subsequent rotation. Furthermore, the first plane 410 and the second plane 510 are in contact, and the first damping part 400 and the second damping part 500 are not easy to slide relative to each other without external force. Therefore, after the cover plate is opened to a certain extent relative to the box, the opening angle is stable.

[0032] Reference Figure 3 and Figure 4 According to some embodiments of this application, the first damping part 400 is further provided with a third plane 430, which is connected to the side of the first inclined surface 420 away from the second damping part 500. The second damping part 500 is further provided with a fourth plane 530, which is connected to the side of the second inclined surface 520 away from the first damping part 400. The third plane 430 and the fourth plane 530 are in sliding engagement.

[0033] It is understandable that during the process of the second connecting part 200 rotating relative to the first connecting part 100 around the second direction, that is, during the process of the cover plate closing the box, the second direction is the opposite of the first direction. The tightness of the contact between the second damping part 500 and the first damping part 400 weakens, the friction decreases, and the elastic force of the elastic element 300 increases. The two are balanced so that the closing process of the cover plate is smooth. After the second damping part 500 slides to its lowest point from the first inclined plane 420, that is, after the first damping part 400 slides to its lowest point from the second inclined plane 520, the fourth plane 530 of the second damping part 500 can abut against the third plane 430 of the first damping part 400. When the second connecting part 200 continues to rotate relative to the first connecting part 100 in the second direction, the fourth plane 530 and the third plane 430 slide relative to each other. Therefore, the friction between the second damping part 500 and the first damping part 400 will not be further weakened, that is, the resistance to relative rotation between the second connecting part 200 and the first connecting part 100 will not be further weakened. It should be understood that the process of closing the cover requires the application of force by hand. This ensures that the force applied by hand will not be too light during subsequent rotation, thus affecting the feel. Furthermore, the third plane 430 and the fourth plane 530 are in contact, and the first damping part 400 and the second damping part 500 are not easy to slide relative to each other without external force. Therefore, the cover is stable after it closes the box.

[0034] Reference Figure 1 and Figure 2 According to some embodiments of this application, the device further includes a rotating shaft 600. The first connecting portion 100 includes a first connecting plate 110 and a second connecting plate 120 connected together. The second connecting portion 200 includes a third connecting plate 210 located on the side of the second connecting plate 120 away from the first connecting plate 110. The elastic element 300 includes a torsion spring 310 located between the first connecting plate 110 and the second connecting plate 120. One end of the torsion spring 310 is connected to the first connecting plate 110, and the other end is connected to the second damping portion 500 or the third connecting plate 210. The first damping portion 400 is installed on the side of the second connecting plate 120 near the third connecting plate 210, and the second damping portion 500 is disposed on the side of the third connecting plate 210 near the second connecting plate 120. The rotating shaft 600 passes through the first connecting plate 110, the torsion spring 310, the second connecting plate 120, the first damping portion 400, the second damping portion 500, and the third connecting plate 210 in sequence.

[0035] It is understood that the rotating shaft 600 is fixed relative to the first connecting plate 110 and the second connecting plate 120 in the first direction, that is, the first connecting plate 110 and the second connecting plate 120 cannot rotate relative to the rotating shaft 600, while the third connecting plate 210 can rotate around the rotating shaft 600, so that the third connecting plate 210 can rotate relative to the first connecting plate 110 and the second connecting plate 120. The elastic element 300 is a torsion spring 310. One end of the torsion spring 310 is connected to the first connecting plate 110, and the other end is connected to the second damping part 500 or the third connecting plate 210. The torsion spring 310 can provide an elastic force that allows the second damping part 500 or the third connecting plate 210 to rotate around a first direction. The second damping part 500 is mounted on the third connecting plate 210, and the second damping part 500 and the third connecting plate 210 can rotate synchronously. Thus, the torsion spring 310 can make the second damping part 500 rotate relative to the first damping part 400, regardless of whether it is connected to the second damping part 500 or the third connecting plate 210, so that the second inclined surface 520 and the first inclined surface 420 can slide together. It is also understandable that the first damping part 400 is installed on the side of the second connecting plate 120 near the third connecting plate 210, and the second damping part 500 is installed on the side of the third connecting plate 210 near the second connecting plate 120. That is, the first damping part 400 and the second damping part 500 are disposed between the second connecting plate 120 and the third connecting plate 210, while the torsion spring 310 is disposed between the first connecting plate 110 and the second connecting plate 120. In this way, the space required for the installation of the torsion spring 310 and the first damping part 400 and the second damping part 500 can be saved. Only the gap between the first connecting plate 110 and the second connecting plate 120 and the gap between the second connecting plate 120 and the third connecting plate 210 is needed. It is also understandable that the rotating shaft 600 can be fitted with the first connecting plate 110, the torsion spring 310, the second connecting plate 120, the first damping part 400, the second damping part 500, and the third connecting plate 210, so as to fix the torsion spring 310, the first damping part 400 and the second damping part 500, and to make the first damping part 400 and the second damping part 500 coaxially arranged, which is conducive to the sliding engagement of the first damping part 400 and the second damping part 500.

[0036] Reference Figure 4 According to some embodiments of this application, the second damping part 500 is provided with a slot 540, and the other end of the torsion spring 310 is engaged in the slot 540.

[0037] It is understood that the torsion spring 310 is connected to the second damping part 500, that is, the torsion spring 310 provides the second damping part 500 with an elastic force to rotate around the first direction. The second damping part 500 can drive the second connecting part 200 to rotate around the first direction. Furthermore, the torsion spring 310 is engaged in the slot 540 of the second damping part 500, thereby facilitating the installation of the torsion spring 310. Specifically, the outer periphery of the second damping part 500 is provided with a slot 540, one side of which is open so that the other end of the torsion spring 310 can be engaged. The torsion spring 310 can drive the second damping part 500 to rotate by pushing the groove wall of the slot 540.

[0038] Reference Figure 1 According to some embodiments of this application, it also includes an adjusting member 700, which is connected to the second connecting plate 120 or the third connecting plate 210 and is used to adjust the distance between the second connecting plate 120 and the third connecting plate 210.

[0039] Understandably, the distance between the second connecting plate 120 and the third connecting plate 210 can be adjusted by adjusting the adjusting member 700, so as to adjust the tightness of the contact between the first damping part 400 and the second damping part 500, thereby adjusting the damping feel during the opening process of the cover plate relative to the box.

[0040] Reference Figure 1 According to some embodiments of this application, the adjusting member 700 includes a nut 710 and a pressure block 720. The pressure block 720 is fixed to one end of the rotating shaft 600. The pressure block 720 abuts against the side of the third connecting plate 210 away from the second connecting plate 120. The other end of the rotating shaft 600 extends out of the side of the first connecting plate 110 away from the second connecting plate 120. The nut 710 abuts against the side of the first connecting plate 110 away from the second connecting plate 120 and is threadedly connected to the other end of the rotating shaft 600 to drive the rotating shaft 600 to move along its axial direction.

[0041] Understandably, when it is necessary to adjust the tightness of the contact between the first damping part 400 and the second damping part 500, the nut 710 is turned, and the rotating shaft 600 will move along its axial direction to drive the pressure block 720 to move along the axial direction of the rotating shaft 600. The pressure block 720 can push the third connecting plate 210 closer to the second connecting plate 120 to improve the tightness of the contact between the second damping part 500 and the first damping part 400, thereby increasing the damping sensation during the rotation of the cover plate. Alternatively, the pressure block 720 can move away from the third connecting plate 210, and the third connecting plate 210 can rebound under its own elastic force, thereby reducing the tightness of the contact between the second damping part 500 and the first damping part 400 to weaken the damping sensation during the rotation of the cover plate.

[0042] Reference Figure 1 and Figure 2According to some embodiments of this application, the first connecting portion 100 further includes a first mounting plate 130, the first connecting plate 110 and the second connecting plate 120 are fixed to the first mounting plate 130, the second connecting portion 200 further includes a second mounting plate 220, and the third connecting plate 210 is fixed to the second mounting plate 220. One of the first mounting plate 130 and the second mounting plate 220 is used to connect to the cover of the storage box, and the other is used to connect to the body of the storage box. At least two of the first connecting plate 110, the second connecting plate 120, the third connecting plate 210, the first damping portion 400 and the second damping portion 500 are provided, and they correspond one-to-one.

[0043] It is understandable that the first mounting plate 130 is used to fix the box body, and the second mounting plate 220 is used to fix the cover plate. When the third connecting plate 210 rotates relative to the second connecting plate 120 around the first direction, it can drive the second mounting plate 220 to rotate relative to the first mounting plate 130 around the first direction, so that the cover plate can open and close the box body. Furthermore, each of the first mounting plates 130 is connected to a second connecting plate 120 at both ends, and two first connecting plates 110 are installed between the two second connecting plates 120, thereby reducing the space occupied. Each of the second mounting plates 220 is connected to a third connecting plate 210 at both ends. The length of the second mounting plate 220 is greater than the length of the first mounting plate 130. The two third connecting plates 210 are located on both sides of the length direction of the first mounting plate 130, that is, on one side of the two second connecting plates 120 respectively. The two third connecting plates 210 correspond one-to-one with the two second connecting plates 120, and each third connecting plate 210 is equipped with a second damping part 500. Each second connecting plate 120 is equipped with a first damping part 400. Thus, through the cooperation of at least two sets of first damping parts 400 and second damping parts 500, the stability of the cover plate when rotating relative to the box is improved.

[0044] In some other embodiments, the first mounting plate 130 may also be fixed to the cover plate, and the second mounting plate 220 may also be used to fix the housing.

[0045] Reference Figure 2 According to some embodiments of this application, the first connecting portion 100 further includes a baffle plate 140, which is disposed on the rotation path of the second damping portion 500.

[0046] It is understandable that when the cover plate rotates relative to the housing to the closed position and / or the limit open position, the second damping part 500 can abut against the blocking plate 140 to limit the second connecting part 200 from continuing to rotate relative to the first connecting part 100, that is, to limit the cover plate from continuing to rotate relative to the housing.

[0047] A storage box according to a second aspect embodiment of the present application includes a cover, a box body, and a buffer structure according to a first aspect embodiment. One of the cover and the box body is connected to a first connecting part 100, and the other is connected to a second connecting part 200. The cover is capable of opening and closing the box body.

[0048] The storage box according to the second aspect embodiment of this application has at least the following beneficial effects: including all the beneficial effects of the buffer structure of the first aspect embodiment, which will not be repeated here.

[0049] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
