Description

Technical Field

[0001] The present application relates to the technical field of hinge structures, and more particularly, to hinge assemblies, armrest boxes, and vehicles. Background Art

[0002] The armrest box of a vehicle generally realizes the relative rotation between the cover plate and the box body through a hinge. After the cover plate is unlocked from the box body, some hinges can drive the cover plate to rotate a small angle relative to the box body, so as to facilitate the user to manually open the cover plate. However, in order to achieve the above function, the structure of the hinge is relatively complex, and the production and processing efficiency is low. Summary of the Utility Model

[0003] The present application provides a hinge assembly, an armrest box, and a vehicle to solve the technical problems of complex structure and low production efficiency of some hinges.

[0004] The present application provides a hinge assembly including a rotating shaft member, a first bracket, a second bracket, and an elastic member. The rotating shaft member has a rotation axis parallel to the first direction. The first bracket includes a first connecting arm sleeved on the rotating shaft member. The second bracket includes a second connecting arm, a first limiting portion, and a second limiting portion. The second connecting arm is spaced from the first connecting arm in the first direction, the second connecting arm is sleeved on the rotating shaft member, the first limiting portion and the second limiting portion are both connected to the second connecting arm, and the first limiting portion and the second limiting portion are spaced from each other in the circumferential direction of the rotating shaft member. The elastic member includes a first abutting portion and a second abutting portion. The first abutting portion is relatively fixed to the first limiting portion, and the second abutting portion is located between the first limiting portion and the second limiting portion. Wherein, the hinge assembly has a first state and a second state, and can switch between the first state and the second state when the first bracket and the second bracket rotate relative to each other. In the first state, the second abutting portion elastically abuts against the first connecting arm, and the second abutting portion is separated from the second limiting portion; in the second state, the second abutting portion abuts against the second limiting portion, and the second abutting portion supports the first connecting arm.

[0005] In the hinge assembly of the present application, in the first state, the first bracket is subjected to a force other than the elastic member and remains relatively still with the second bracket, and the elastic member applies an elastic force to the first bracket through the second abutting top portion, so that the first bracket has a tendency to rotate relative to the second bracket. When the aforementioned force is removed, the first bracket can rotate relative to the second bracket around the rotation axis driven by the second abutting top portion until the second abutting top portion abuts against the second limiting portion, and the elastic force applied by the second abutting top portion to the first connecting arm can overcome the gravity of the first bracket, thereby keeping the first bracket and the second bracket relatively still, so that the hinge assembly switches to the second state. Therefore, the hinge assembly of the present application can automatically switch from the first state to the second state and remain locked in the second state.

[0006] At the same time, since the first limiting part and the second limiting part are both integrated on the second connecting arm, and the elastic member is also installed between the first limiting part and the second limiting part, the integration of parts is high, and the layout space occupied by the hinge assembly can be saved. In addition, during the assembly process of the hinge assembly, the second bracket, the elastic member and the rotating shaft member can be pre-assembled into a semi-finished product, and then the first bracket and the semi-finished product can be assembled. Compared with the assembly process of the existing hinge assembly, the assembly process of the hinge assembly of this embodiment is simple, and the matching relationship of each part is simple, so that the production cycle of the hinge assembly can be improved, and the assembly production efficiency can be improved.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in the description of the present application herein are only for the purpose of describing specific implementation manners, and are not intended to limit the present application. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0042] Some implementation manners of the present application will be described in detail. Without conflict, the following implementation manners and the features in the implementation manners can be combined with each other.

[0043] Refer to Figure 1 , this embodiment provides a vehicle 300, including a vehicle body 301 and an armrest box 200. The vehicle body 301 defines an interior space 302. Some vehicles 300 further include seats (not shown in the figure), and the seats are disposed in the interior space 302. The armrest box 200 is disposed on one side of the seat and is used for a user to place an arm. In some implementation manners, the armrest box 200 is disposed between two adjacent seats.

[0044] Further refer to Figure 2, the armrest box 200 includes a box body 201 and a box cover 204. The box body 201 defines a receiving cavity 202 with an opening 203. A user can take and place items in and out of the receiving cavity 202 via the opening 203. The box cover 204 is rotatably connected to the box body 201 through a hinge assembly 100, and the box cover 204 can open the box body 201 or cover the opening 203 of the box body 201. In some embodiments, the armrest box 200 further includes a locking structure (not shown in the figure), and the locking structure is connected between the box cover 204 and the box body 201, and the locking structure is used to keep the box cover 204 covering the opening 203 of the box body 201. The locking structure can adopt various forms such as a snap-type locking structure, a push-type locking structure, a PUSHPUSH structure, etc., which will not be elaborated here.

[0045] Refer to in conjunction with Figures 3 to 6 , the hinge assembly 100 includes a rotating shaft member 10, a first bracket 20, a second bracket 30, and an elastic member 40. The rotating shaft member 10 has a rotation axis L, and the rotation axis L is parallel to the first direction M1. In this embodiment, the first direction M1 is the Y-axis direction in the vehicle coordinate system of the vehicle 300. The first bracket 20 includes a first connecting arm 21. The first connecting arm 21 is sleeved on the rotating shaft member 10. The second bracket 30 includes a second connecting arm 31, a first limiting portion 32, and a second limiting portion 33 (shown in Figure 5 ). Both the first limiting portion 32 and the second limiting portion 33 are connected to the second connecting arm 31, and the first limiting portion 32 and the second limiting portion 33 are spaced apart along the circumferential direction of the rotating shaft member 10. The second connecting arm 31 is spaced apart from the first connecting arm 21 in the first direction M1 (shown in Figure 6 ). The second connecting arm 31 is sleeved on the rotating shaft member 10. The elastic member 40 includes a first abutting portion 41 and a second abutting portion 42. The first abutting portion 41 is relatively fixed to the first limiting portion 32, and the second abutting portion 42 is located between the first limiting portion 32 and the second limiting portion 33. In this embodiment, the first abutting portion 41 can be relatively fixed to the first limiting portion 32 by abutting, and the first abutting portion 41 can abut against the first limiting portion 32 under the elastic force of the elastic member 40 itself, so as to be relatively fixed to the first limiting portion 32, and the assembly efficiency of the hinge assembly 100 can be improved. Or the first abutting portion 41 can be fixedly connected to the first limiting portion 32 by connection methods such as threaded connection and pin connection, so as to be relatively fixed to the first limiting portion 32. The hinge assembly 100 has a first state and a second state, and can switch between the first state and the second state when the first bracket 20 and the second bracket 30 rotate relative to each other. Refer to Figure 3 , in the first state, the second abutting portion 42 abuts against the first connecting arm 21, and the second abutting portion 42 is separated from the second limiting portion 33. Refer to Figure 4, in the second state, the second abutting top 42 abuts against the second limiting part 33, the second abutting top 42 supports the first connecting arm 21, and the first bracket 20 can be separated from the second abutting top 42 under the action of an external force and rotate relative to the second bracket 30 around the rotation axis L in the direction from the first limiting part 32 to the second limiting part 33. Among them, the direction from the first limiting part 32 to the second limiting part 33 is Figures 3 to 5 the clockwise direction in Figures 3 to 5 . During the process that the first bracket 20 rotates relative to the second bracket 30 in the clockwise direction in

[0046] due to the second abutting top 42 remaining abutted against the second limiting part 33, the separation between the first bracket 20 and the second abutting top 42 is realized. Figure 3 For the hinge assembly 100 of this embodiment, referring to Figure 4 , in the first state, restricted by the locking structure of the armrest box 200, the first bracket 20 and the second bracket 30 remain relatively stationary. The second abutting top 42 exerts an elastic force on the first bracket 20 and makes the first bracket 20 have a tendency to rotate relative to the second bracket 30. When the user opens the locking structure, the first bracket 20 can be driven by the second abutting top 42 to rotate relative to the second bracket 30 around the rotation axis L, and the lid 204 rotates relative to the box body 201 to open the box body 201. Referring to

[0047] , when the lid 204 rotates relative to the box body 201 until the second abutting top 42 abuts against the second limiting part 33, the second abutting top 42 no longer undergoes elastic deformation under the limitation of the second limiting part 33. The elastic force exerted by the second abutting top 42 on the first connecting arm 21 is greater than the gravity of the first connecting arm 21 and the lid 204, so that the first bracket 20 and the second bracket 30 remain relatively stationary. Furthermore, the hinge assembly 100 switches to the second state, and the lid 204 and the box body 201 are kept open, facilitating the user to reach into the gap between the lid 204 and the box body 201 to rotate the lid 204 relative to the box body 201, and then take and place items in the receiving cavity 202.

[0048] In some embodiments, the first bracket 20 further includes a first connecting plate 22. The first connecting arm 21 is connected to the first connecting plate 22. When the hinge assembly 100 is in the first state, the first connecting plate 22 is parallel to the preset plane N1. The preset plane N1 is parallel to the first direction M1. When the vehicle 300 is in a static state, the preset plane N1 is parallel to the horizontal plane, and the plane where the opening 203 is located is parallel to the horizontal plane. The first connecting plate 22 is connected to the lid 204. When the hinge assembly 100 is in the first state, the lid 204 is fastened to the box body 201, and the first connecting plate 22 is parallel to the preset plane N1. When the hinge assembly 100 is in the second state, the included angle between the first connecting plate 22 and the preset plane N1 is the opening angle α. 1° ≤ α ≤ 20°. The opening angle α can be set to one of 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°.

[0049] Obviously, the specific angle of the opening angle α can be adjusted according to different design requirements. The angle of the opening angle α can be adjusted according to the elastic force of the elastic member 40 and the positions of the first limiting portion 32 and the second limiting portion 33 on the second connecting arm 31.

[0050] In other embodiments, the lid 204 can also be connected to the first connecting arm 21.

[0051] At the same time, since both the first limiting portion 32 and the second limiting portion 33 are integrated on the second connecting arm 31, and the elastic member 40 is also installed between the first limiting portion 32 and the second limiting portion 33, the integration degree of the parts is relatively high, which can save the layout space occupied by the hinge assembly 100. Moreover, during the assembly process of the hinge assembly 100, the second bracket 30, the elastic member 40 and the rotating shaft member 10 can be pre-assembled into a semi-finished product, and then the first bracket 20 is assembled with the semi-finished product. Compared with the existing assembly process of the hinge assembly 100, the assembly process of the hinge assembly 100 in this embodiment is simple, and the cooperation relationship of each part is simple, so that the production beat of the hinge assembly 100 can be improved, and the assembly production efficiency can be improved.

[0052] In some embodiments, with reference to Figure 5, the hinge assembly 100 further has a third state. The second bracket 30 further includes a third limiting portion 34. The third limiting portion 34 is connected to the second connecting arm 31. Along the circumferential direction of the rotating shaft member 10, the third limiting portion 34 is located on the side of the second limiting portion 33 away from the first limiting portion 32. The first bracket 20 further includes a limiting portion 23. The limiting portion 23 is connected to the first connecting arm 21. The hinge assembly 100 further has a third state. In the third state, the limiting portion 23 abuts against the third limiting portion 34, and the included angle between the first bracket 20 and the second bracket 30 is greater than the included angle between the first bracket 20 and the second bracket 30 of the hinge assembly 100 in the second state.

[0053] After the hinge assembly 100 is switched to the second state under the action of the elastic member 40, the user can manually rotate the lid 204 so that the first bracket 20 rotates relative to the second bracket 30 until the limiting portion 23 abuts against the third limiting portion 34. Since the second bracket 30 remains fixed, the third limiting portion 34 limits the rotation of the first bracket 20, causing the hinge assembly 100 to enter the third state.

[0054] In some embodiments, refer to Figure 5 , in the third state, the included angle between the first connecting plate 22 and the preset plane N1 is the limit angle β, 60° ≤ β ≤ 135°. The limit angle β can be set to any one of 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130° or 135°. If the limit angle β is too small, the opening degree of the opening 203 is insufficient, and it is difficult for the user to take and place items. If the limit angle β is too large, the opened lid 204 will occupy a large space in the second direction M2, easily causing waste of the space of the vehicle 300. Limiting the limit angle β between 60° and 135° can not only reduce the occupied space of the armrest box 200, but also ensure the convenience of the user to take and place items.

[0055] In addition, when β ≥ 90°, the limiting portion 23 can keep abutting against the third limiting portion 34 under the action of the gravity of the first bracket 20, so that the hinge assembly 100 can be kept in the third state, which is beneficial for the user to take and place items from the opening 203.

[0056] In some embodiments, refer to Figure 6, the first bracket 20 includes a first connecting arm 21a and a first connecting arm 21b. The second bracket 30 includes a second connecting arm 31a and a second connecting arm 31b. The first connecting arm 21a and the first connecting arm 21b are spaced apart along a first direction M1, the second connecting arm 31a and the second connecting arm 31b are spaced apart along the first direction M1. Along the first direction M1, the second connecting arm 31a and the second connecting arm 31b are located between the first connecting arm 21a and the first connecting arm 21b, and the first connecting arm 21a and the second connecting arm 31a are located on one side of the hinge assembly 100 along the first direction M1, and the first connecting arm 21b and the second connecting arm 31b are located on the other side of the hinge assembly 100 along the first direction M1. The hinge assembly 100 includes two rotating shaft members 10 and two elastic members 40. One rotating shaft member 10 and one elastic member 40 are provided between the first connecting arm 21a and the first connecting arm 21a. Another rotating shaft member 10 and another elastic member 40 are provided between the first connecting arm 21b and the second connecting arm 31b.

[0057] In this way, the forces on both sides of the hinge assembly 100 along the first direction M1 are relatively balanced, thereby improving the rotational stability between the first bracket 20 and the second bracket 30, and enabling the hinge assembly 100 to reliably switch from the first state to the second state.

[0058] In other embodiments, along the first direction M1, the first connecting arm 21a and the first connecting arm 21b are located between the second connecting arm 31a and the second connecting arm 31b.

[0059] In other embodiments, one rotating shaft member 10 can be provided, one elastic member 40 can be provided. Along one side of the first direction M1, the rotating shaft member 10 is connected between the first connecting arm 21a and one second connecting arm 31a, and the elastic member 40 is installed between the first connecting arm 21a and the second connecting arm 31a. Along the other side of the first direction M1, a sliding fit can be carried out between the first connecting arm 21b and the second connecting arm 31b through a sliding groove (not shown in the figure) and a swing arm (not shown in the figure). Among them, the sliding groove can be provided on the first connecting arm 21b, and the swing arm can be connected to the second connecting arm 31b.

[0060] In some embodiments, refer to Figure 6 , the two first connecting arms 21 are bent and connected to both sides of the first connecting plate 22 along the first direction M1. The first connecting plate 22 is connected to the box cover 204. The first connecting plate 22 can be provided with a plurality of concave and convex structures to improve the strength of the first connecting plate 22, thereby improving the connection stability between the second connecting plate 35 and the box body 201.

[0061] In some embodiments, refer to Figure 6, the second bracket 30 further includes a second connecting plate 35. Two second connecting arms 31 are bent and connected to both sides of the second connecting plate 35 along the first direction M1. The second connecting plate 35 is connected to the box body 201. The second connecting plate 35 may be provided with a plurality of concave and convex structures to improve the strength of the second connecting plate 35, thereby improving the connection stability between the second connecting plate 35 and the box body 201.

[0062] In some embodiments, referring to Figure 6 , the first connecting arm 21a, the second connecting arm 31a and the first connecting arm 21b, the second connecting arm 31b are symmetric about the symmetry plane N2 (seen in Figure 9 ). The symmetry plane N2 is a plane perpendicular to the first direction M1.

[0063] In some embodiments, the plane where the second connecting plate 35 is located is perpendicular to the second direction M2. The second direction M2 intersects the first direction M1. The second direction M2 can be set as the X-axis direction of the vehicle coordinate system. When the hinge assembly 100 is in the first state, the plane where the first connecting plate 22 is located is perpendicular to the third direction M3. The third direction M3 intersects the first direction M1 and the second direction M2. The third direction M3 can be set as the Z-axis direction of the vehicle coordinate system. In this way, the second connecting plate 35 can be easily and fixedly connected to the box body 201, and the first connecting plate 22 can be easily connected to the box cover 204.

[0064] Next, the structures of the first connecting arm 21, the second connecting arm 31, the rotating shaft member 10 and the elastic member 40 on one side of the hinge assembly 100 along the first direction M1 will be described. The structures and fits of the related components on the other side of the hinge assembly 100 along the second direction M2 are the same.

[0065] In some embodiments, when the hinge assembly 100 is in the first state or the second state, the elastic member 40 remains in an elastically deformed state, and the first abutting portion 41 is kept abutted against the first limiting portion 32 under the elastic force of the elastic member 40, realizing the connection between the first abutting portion 41 and the first limiting portion 32. Moreover, this assembly method does not require further fixing procedures between the elastic member 40 and the first limiting portion 32, which can improve the assembly efficiency of the hinge assembly 100. In other embodiments, the first abutting portion 41 and the first limiting portion 32 can also be fixedly connected through structures such as screws and pins to improve the movement stability of the hinge assembly 100.

[0066] In some embodiments, referring to Figure 6, the second abutting top portion 42 includes a first portion 421 and a second portion 422. The second portion 422 is connected to one side of the first portion 421 along the first direction M1, and extends from the side of the first connecting arm 21 facing away from the second connecting arm 31. In the first state, the first portion 421 is spaced apart from the second limiting portion 33, the first portion 421 abuts against the first bracket 20, and applies an elastic force to the first bracket 20. In the second state, the second portion 422 abuts against the second limiting portion 33, and the first portion 421 supports the first connecting arm 21.

[0067] Thus, by dividing the second abutting top portion 42 into the first portion 421 and the second portion 422, the rotation between the first bracket 20 and the second bracket 30 can be achieved in the first state, and the first bracket 20 and the second bracket 30 can be kept relatively stationary in the second state.

[0068] In some embodiments, referring to Figures 7 to 9 , the elastic member 40 includes a torsion spring 40a. The torsion spring 40a includes a spiral portion 43, a first torsion arm 41a, and a second torsion arm 42a. The spiral portion 43 is sleeved on the rotating shaft member 10. The first torsion arm 41a is connected to one end of the spiral portion 43 along the first direction M1, and the first torsion arm 41a is the first abutting top portion 41. The second torsion arm 42a is connected to the other end of the spiral portion 43 along the first direction M1, and the second torsion arm 42a is the second abutting top portion 42. The extending directions of the first torsion arm 41a and the second torsion arm 42a intersect, that is, the projections of the first torsion arm 41a and the second torsion arm 42a along the first direction M1 do not overlap each other.

[0069] In some embodiments, the spiral portion 43 includes three loop portions 43a. The three loop portions 43a are arranged to overlap each other substantially along the first direction M1. The first torsion arm 41a extends from one loop portion 43a at one end of the spiral portion 43 along the first direction M1 and abuts against the first limiting portion 32. In the first state, the second torsion arm 42a extends from another loop portion 43a at the other end of the spiral portion 43 along the first direction M1 and abuts against the first bracket 20. In the second state, the second torsion arm 42a abuts against the second limiting portion 33. In other embodiments, the number of the loop portions 43a is not limited.

[0070] In some embodiments, referring to Figure 7 , the second torsion arm 42a includes a limiting section 422a and an abutting section 421a. The abutting section 421a is connected to the limiting section 422a, and the abutting section 421a extends from one side of the first connecting arm 21 along the first direction M1 to the other side of the first connecting arm 21 along the first direction M1. The abutting section 421a is the first portion 421, and the limiting section 422a is the second portion 422.

[0071] The torsion spring 40a has the characteristic of being easy to assemble. After the rotating shaft member 10 is installed on the second connecting arm 31, the torsion spring 40a can be directly sleeved on the rotating shaft member 10, and the first torsion arm 41a is abutted against the first limiting portion 32, and the limiting section 422a of the second torsion arm 42a is abutted against the second limiting portion 33, and the abutting section 421a extends along the first direction M1. When assembling the first bracket 20 subsequently, the abutting section 421a is abutted against the side of the first connecting arm 21 close to the rotating shaft member 10, thereby further improving the assembly efficiency of the hinge assembly 100. In addition, the spiral portion 43 can further increase the bending deformation amount of the first abutting portion 41 and the second abutting portion 42, so that the elastic member 40 provides sufficient elastic force to overcome the weights of the second bracket 30 and the lid 204, and the lid 204 is opened relative to the box body 201.

[0072] In some embodiments, referring to Figure 9 , the limiting section 422a extends along the radial direction of the rotating shaft member 10, and the axial direction of the rotating shaft member 10 is parallel to the first direction M1. The abutting section 421a is bent and connected to one end of the limiting section 422a departing from the rotating shaft member 10 and extends along the first direction M1. In this way, the second torsion arm 42a only needs to be formed by bending on the basis of the ordinary leg of the torsion spring 40a, and has the characteristics of simple structure and easy forming. Moreover, the lengths of the first torsion arm 41a and the second torsion arm 42a can both be adjusted according to actual needs. When the first limiting portion 32 and the second limiting portion 33 are installed at different positions on the second connecting arm 31, the first torsion arm 41a and the second torsion arm 42a with appropriate lengths can be simply constructed and respectively cooperate with the first limiting portion 32 and the second limiting portion 33, so as to have a wide range of applications.

[0073] In some embodiments, referring to Figure 9 , the end of the second limiting portion 33 close to the first connecting arm 21 is spaced from the first connecting arm 21. The limiting section 422a includes a first arm section 4221 and a second arm section 4222. The first arm section 4221 is connected to the spiral portion 43. The second arm section 4222 is connected between the first arm section 4221 and the abutting section 421a. The second arm section 4222 is offset from the first arm section 4221 along the first direction M1, and the projection of the second arm section 4222 on the second limiting portion 33 along the second direction M2 at least partially overlaps the end of the second limiting portion 33 close to the first connecting arm 21. In this way, during the rotation of the first bracket 20 relative to the second bracket 30, the second limiting portion 33 will not interfere with the first bracket 20, ensuring the smooth rotation of the hinge assembly 100. At the same time, it can also ensure that when the hinge assembly 100 is in the second state, the second arm section 4222 abuts against the second limiting portion 33, so that the hinge assembly 100 remains in the second state.

[0074] Figure 10 and Figure 11The elastic member 40 of another embodiment is shown. Among them, in Figure 10 the hinge assembly 100 is in the first state, and in Figure 11 the hinge assembly 100 is in the second state. In this embodiment, the elastic member 40 includes an elastic column 40b. The elastic column 40b includes a first end 41b and a second end 42b. The first end 41b and the second end 42b are located at both ends of the elastic column 40b in the length direction. The first end 41b abuts against the first limiting portion 32. The second end 42b includes a first side portion 421b and a second side portion 422b. The first side portion 421b is connected to one side of the second side portion 422b along the first direction M1. In the first state, the first side portion 421b is spaced apart from the first connecting arm 21. The second side portion 422b is spaced apart from the second limiting portion 33, and the first side portion 421b abuts against the first connecting arm 21. In the second state, the first side portion 421b remains in abutment against the first connecting arm 21 to overcome the gravity of the first connecting arm 21. At the same time, the second side portion 422b abuts against the second limiting portion 33. Among them, the first side portion 421b is the first part 421, and the second side portion 422b is the second part 422.

[0075] In some embodiments, referring to Figure 10 and Figure 11 , for the convenience of the installation stability of the elastic column 40b in the hinge assembly 100, the first limiting portion 32 may be provided with a protruding positioning column, and the elastic column 40b is sleeved on the outer periphery of the positioning column or received inside the positioning column. In other embodiments, the elastic column 40b may also be fixedly connected to the first limiting portion 32.

[0076] In other embodiments, the elastic member 40 may also be configured as an elastic element such as a spring, a tension spring, a C-shaped spring or a spring piece, and its structural principle may refer to the structural principle of the elastic column 40b or the torsion spring 40a, which will not be elaborated here.

[0077] In some embodiments, please refer to Figure 8 and Figure 9 again. The hinge assembly 100 further includes a bushing 12. The length direction of the bushing 12 is parallel to the first direction M1. The bushing 12 is pressed between the first connecting arm 21 and the second connecting arm 31. The bushing 12 is used to provide rotational damping between the first connecting arm 21 and the second connecting arm 31. The bushing 12 is further provided with a communication hole 121, and the communication hole 121 penetrates the bushing 12 along the first direction M1. The first connecting arm 21 is provided with a first connecting hole 213, and the first connecting hole 213 penetrates the first connecting arm 21 along the first direction M1. The second connecting arm 31 is provided with a second connecting hole 314, and the second connecting hole 314 penetrates the second connecting arm 31 along the first direction M1. The rotating shaft member 10 passes through the first connecting hole 213, the communication hole 121 and the second connecting hole 314.

[0078] After the hinge assembly 100 switches to the second state, the user can manually lift the lid 204 and rotate the second bracket 30 relative to the first bracket 20. After the user lifts the lid 204 and rotates it to any position and then releases the lid 204, since the bushing 12 provides rotational damping between the first connecting arm 21 and the second connecting arm 31, the second bracket 30 hovers relative to the first bracket 20, thereby improving the user experience.

[0079] In some embodiments, referring to Figure 8 , the rotating shaft member 10 includes a shaft pin 11 and a pressing flange 111. The pressing flange 111 is connected to one end of the shaft pin 11. The pressing flange 111 presses against the side of the second connecting arm 31 facing away from the first connecting arm 21, and the other end of the shaft pin 11 extends to the side of the first connecting arm 21 facing away from the second connecting arm 31. The locking member 13 is sleeved on the end of the shaft pin 11 extending out of the first connecting arm 21 and locks the first connecting arm 21 to the bushing 12, so as to press the bushing 12 between the first connecting arm 21 and the second connecting arm 31.

[0080] In some embodiments, the locking member 13 can be set as a fastening structure such as a locking piece, a nut, etc.

[0081] In some embodiments, referring to Figure 9 , the hinge assembly 100 further includes a first gasket 14 and a second gasket 15. The first gasket 14 is clamped between the first connecting arm 21 and the locking member 13. The second gasket 15 is clamped between the second connecting arm 31 and the pressing flange 111.

[0082] In some embodiments, referring to Figure 8 and Figure 9 , the first gasket 14 includes a first extending section 141, and the first extending section 141 extends into the first connecting hole 213. The second gasket 15 includes a second extending section 151, and the second extending section 151 extends into the second connecting hole 314. In this way, the installation stability of the rotating shaft member 10 between the first connecting arm 21 and the second connecting arm 31 is improved, and the possibility of axial movement of the rotating shaft member 10 during the rotation of the first bracket 20 and the second bracket 30 can be greatly reduced.

[0083] In some embodiments, referring to Figure 8The first connecting arm 21 includes a rotating section 211 and a force-bearing section 212. The rotating section 211 is connected to the force-bearing section 212, and the rotating section 211 is connected to the rotating shaft 10. The rotating section 211 has a first connecting hole 213. In the first state, the rotating section 211 extends relative to the force-bearing section 212 in a direction close to the first abutting top 41, and the second portion 422 elastically abuts against a side of the force-bearing section 212 close to the first abutting top 41. In this way, the structure of the first connecting arm 21 is simple, less materials are used, the cost of the hinge assembly 100 is saved, and interference during the rotation of the first bracket 20 can be avoided.

[0084] In some embodiments, in the first state, the rotating section 211 is connected to the side of the force-bearing section 212 along the second direction M2 close to the first abutting portion 41. The limiting portion 23 is connected to the side of the force-bearing section 212 along the third direction M3 away from the first limiting portion 32 or the second limiting portion 33. In this way, when the hinge assembly 100 rotates from the second state to the third state, the force-bearing section 212 rotates along the side of the third direction M3 along the circumference of the rotating shaft 10 toward the direction close to the third limiting portion 34 until the limiting portion 23 abuts against the third limiting portion 34, and then the hinge assembly 100 reaches the third state.

[0085] In some embodiments, when the hinge assembly 100 is in the third state, the opening 203 of the box body 201 is completely open along the third direction M3.

[0086] In some embodiments, see Figure 8 The first connecting arm 21 further includes an extension section 214. The extension section 214 extends along the third direction M3. One end of the extension section 214 is connected to the first connecting plate 22, and the other end of the extension section 214 is connected to an end of the force-bearing section 212 away from the rotating section 211. The force-bearing section 212 is connected to the extension section 214 by bending, and is inclined relative to the vertical section in the direction close to the rotating shaft 10.

[0087] In some embodiments, see Figure 6 and Figure 8The second connecting arm 31 includes a first plate segment 311 and a second plate segment 312. The first plate segment 311 is spaced apart from the rotating shaft member 10 along the second direction M2. The second plate segment 312 is connected to a side of the first plate segment 311 close to the rotating shaft member 10, and a second connecting hole 314 is provided in the second plate segment 312. The second plate segment 312 is opposite to and spaced apart from the rotating segment 211 along the first direction M1. The rotating shaft member 10 is connected to the second plate segment 312. The first limiting portion 32 is connected to an end of the second plate segment 312 that is away from the first plate segment 311 along the second direction M2. The second limiting portion 33 is connected to an end of the first plate segment 311 that is close to the rotating shaft member 10 along the second direction M2, and the second limiting portion 33 is spaced apart from the rotating shaft member 10 along the second direction M2. In this way, the second connecting arm 31 has a simple structure and uses less material, which saves the cost of the hinge assembly 100 and facilitates the installation of the second limiting portion 33 on the first plate segment 311 to limit the hinge assembly 100 to the second state.

[0088] In some embodiments, see Figure 8 The first limiting portion 32 includes a first bending plate 321. The first bending plate 321 is connected to the second connecting arm 31 and extends along the first direction M1 toward the first connecting arm 21. The second limiting portion 33 includes a second bending plate 331. The second bending plate 331 is connected to the second connecting arm 31 and extends along the first direction M1 toward the first connecting arm 21. The third limiting portion 34 includes a third bending plate 341. The third bending plate 341 is connected to the second connecting arm 31 and extends along the first direction M1 toward the first connecting arm 21. In this way, the first limiting portion 32, the second limiting portion 33 and the third limiting portion 34 can be integrally formed on the second connecting arm 31, thereby improving the limiting reliability of the first limiting portion 32, the second limiting portion 33 and the third limiting portion 34.

[0089] In some embodiments, see Figure 8 and Figure 9 The projection of the third bending plate 341 along the second direction M2 overlaps with the first connecting arm 21 to ensure that the third bending plate 341 can limit the first connecting arm 21.

[0090] In other embodiments, the first bending plate 321, the second bending plate 331 and the third bending plate 341 can be connected to the second connecting arm 31 in a detachable manner, and the second connecting arm 31 can be set at multiple installation positions distributed in the third direction M3 to facilitate adjusting the positions of the first bending plate 321 and the second bending plate 331, and then adjusting the size of the opening angle α and the size of the limit angle β to meet the usage requirements of different users.

[0091] In some embodiments, a first mounting groove (not shown in the figures) is provided on the surface of the first bending plate 321, and the first torsion arm 41a is received in the first mounting groove. A second mounting groove (not shown in the figures) is provided on the surface of the second bending plate 331. When the hinge assembly 100 enters the second state, the second torsion arm 42a extends into the second mounting groove, and the second mounting groove limits the second torsion arm 42a. In this way, the first mounting groove can improve the position stability of the first torsion arm 41a, and the second mounting groove can improve the position stability of the second torsion arm 42a, thereby improving the cooperation reliability between the elastic member 40 and the first limiting portion 32 and the second limiting portion 33. During the driving of the vehicle 300, the second torsion arm 42a is not likely to generate relative displacement with the second bending plate 331 either, thereby improving the stability of the hinge assembly 100 in the second state.

[0092] In some embodiments, referring to Figure 6 , a reinforcing convex portion 215 is provided on the surface of the first connecting arm 21, and a reinforcing concave portion 313 is provided on the surface of the second connecting arm 31. In this way, the strength of the first connecting arm 21 and the strength of the second connecting arm 31 can be improved.

[0093] The above embodiments are only used to illustrate the technical solutions of the present application and not to limit them. Although the present application has been described in detail with reference to the above preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
