The base 221 is formed with a second notch 221a (see fig. 12). The protrusion 222 forms a receiving groove 222a (see fig. 12). The mount 22 is attached at the first notch 21 b. The projection 222 is located in the accommodation space 21 a. The receiving groove 222a is open facing the side wall of the housing 21. The receiving groove 222a and the side wall of the housing 21 jointly enclose to form a first shaft hole 22a (see fig. 4). The rotation shaft 30 extends into the first shaft hole 22a through the connection plate 12 and the seat body 221 so that the cover case 11 can be switched between the open position and the closed position covering the housing 21. In the state that the cover 11 is located at the closed position, the portion of the connecting plate 12 is located in the second notch 221a to close the second notch 221a, and the portion of the seat body 221 and the portion of the connecting plate 12 jointly close the first notch 21 b.

The first shaft hole 22a is formed by enclosing the receiving groove 222a and the side wall of the housing 21, and the rotating shaft 30 passes through the connecting plate 12 and the seat body 221 and is disposed in the first shaft hole 22a, i.e., the rotating shaft 30 passes through the connecting plate 12 and the seat body 221 which are located in the first notch 21b and is disposed in the first shaft hole 22a, and the seat body 221 and the protruding portion 222 are used to bear bending moment and torque. Thus, under the condition that the mounting seat 22 can bear a sufficiently large bending moment and torque, the protrusion 222 can bear most of the acting force from the rotating shaft 30, and the size of the portion where the seat body 221 is connected with the rotating shaft 30 can be made small, that is, the size of the portion where the seat body 221 is located in the first notch 21b is made as small as possible. Under the state that the cover shell 11 is located at the closed position, the user observes the box cover 10 and the box body 20 from the side of the shell 21 departing from the protruding part 222, most of the structure of the installation seat 22 is hidden in the shell 21, because the part of the seat body 221 located in the first notch 21b is small in size, the visual effect of an integrated structure between the seat body 221 and the connecting plate 12 can be achieved, the problem that the part of the seat body 221 connected with the rotating shaft 30 has to be large in size in order to ensure the effective stress of the installation seat 22, and the situation that the connecting plate 12 and the seat body 221 are segmented visually is avoided, in industrial design, the structure of the embodiment of the application can greatly improve the aesthetic degree, and increase the texture and the product expressive force. In addition, the portion of the seat body 221 located in the first notch 21b can limit the movement of the mounting seat 22 along the axial direction of the rotating shaft 30. Since the receiving groove 222a is open towards the sidewall of the housing 21, the receiving groove 222a and the sidewall of the housing 21 together enclose the first shaft hole 22a, so that the protrusion 222 can be tightly attached to the sidewall of the housing 21, the distance between the protrusion 222 and the sidewall of the housing 21 is reduced, the mounting seat 22 is prevented from occupying too much space in the box 20, and the structure of the box 20 is more compact.

Note that the second direction is opposite to the first direction. Illustratively, the first direction is clockwise, and the second direction is counterclockwise. Of course, the first direction is counterclockwise, and the second direction is clockwise. The inner side of the holder body 221 refers to a side of the housing 21 close to the accommodating space 21 a. In contrast, the outer side of the seat 221 refers to a side of the housing 21 away from the accommodating space 21 a. That is, the inner side of the seat body 221 and the outer side of the seat body 221 refer to two opposite sides of the seat body 221, and for convenience of description of the present application, the embodiments of the present application define the inner side of the seat body 221 and the outer side of the seat body 221.

The end surface of the support rib 2211 facing the outside of the housing 21 is formed with a step surface 2211a, and the step surface 2211a is supported on the bottom wall of the first notch 21 b. The two connecting ribs 2212 are respectively connected with two ends of the supporting rib 2211. The supporting rib 2211 and the two connecting ribs 2212 jointly enclose to form a second gap 221 a. The protrusion 222 is connected to the connecting rib 2212, the rotating shaft 30 passes through the connecting rib 2212 and extends into the first shaft hole 22a, and the supporting rib 2211 and the two connecting ribs 2212 are connected to the first notch 21 b. That is, the portion of the connecting rib 2212 and the portion of the supporting rib 2211 are both located in the first gap 21b and together with the portion of the connecting plate 12 close the first gap 21 b. Thus, the sidewall of the first notch 21b is used to limit the seat 221 to move along the axial direction of the rotating shaft 30, and the bottom wall of the first notch 21b is used to limit the seat 221 to move downward, so as to improve the structural stability of the mounting seat 22.

In some embodiments, referring to FIGS. 1, 7, 9 and 12, the length of the portion of the connecting rib 2212 (FIG. 7) located in the first notch 21b (FIG. 12) along the axial direction of the rotating shaft 30 (FIG. 9) is A, wherein A is 0.5mm ≦ A ≦ 1.2 mm. For example, A may be 0.5mm, 0.8mm, 1.0mm, 1.1mm, 1.2mm, or the like. In some embodiments, the length of the first notch 21B in the axial direction of the shaft 30 is B, wherein 1/25 ≦ A/B ≦ 1/15. For example, the ratio of A to B can be 1:25, 1:24, 1:23, 1:21, 1:20, 1:18, 1:15, and the like. Thus, under the condition of ensuring the force bearing capability of the part of the seat body 221 located in the first notch 21b, the length of the part of the connecting rib 2212 located in the first notch 21b along the axial direction of the rotating shaft 30 is small enough, so that the visual effect that the part of the connecting rib 2212 located in the first notch 21b and the connecting plate 12 are almost completely integrated is achieved, and the appearance is further improved.

In an embodiment, referring to fig. 8 to 11 and fig. 15 to 16, the connecting plate 12 includes a first plate 121 and a second plate 122. The first plate body 121 is formed with an avoiding groove 121a on each of opposite sides in the axial direction of the rotating shaft 30, and when the cover case 11 is in the closed position, the portion of the connecting rib 2212 is located in the avoiding groove 121a, and the portion of the connecting rib 2212, the portion of the supporting rib 2211 and the first plate body 121 together close the first notch 21 b. The second plate 122 includes a connection portion 1221 and an extension portion 1222 extending from the connection portion 1221 toward the cap 10. The connection portion 1221 is connected to a side of the first plate body 121 adjacent to the accommodation space 21 a. The extension 1222 is connected with the cover case 11. The connecting portion 1221 is formed with a second shaft hole 1221a provided along the axial direction of the rotating shaft 30, and the rotating shaft 30 is inserted into the second shaft hole 1221 a.

The rotation shaft 30 is inserted through the second shaft hole 1221a and the first shaft hole 22a such that the rotation shaft 30 connects the second plate 122 and the protrusion 222. Thus, the second plate 122 is subjected to bending moment and torque, that is, the second plate 122 is mainly stressed. And the extension 1222 is coupled with the cover case 11 so as to enhance the force-bearing capacity of the second plate 122. Because the connecting portion 1221 is connected with one side of the first plate body 121 close to the accommodating space 21a, the first plate body 121 can cover the rotating shaft 30, the connecting portion 1221 and other structures of the seat body 221, so that the user cannot see the internal structure of the box body 20 from the side of the first plate body 121 departing from the accommodating space 21a, and the appearance of the storage box is further improved.

Specifically, the extension 1222 is connected to the cover case 11, the extension 1222 may be welded to the cover case 11, or the extension 1222 is connected to the cover case 11 by a connector, which may be a bolt (see fig. 17 and 18).

In some embodiments, referring to fig. 9, 10 and 15, the contact seam between the support ribs 2211 and the outer rim portion 1212 is flush with the contact seam between the cover shell 11 and the housing 21. In this way, a visual effect of a gap between the support rib 2211 and the outer edge portion 1212 and the cover case 11 and the case 21 is avoided, and the beauty is further improved.

Illustratively, the first texture may be a diagonal, a herringbone texture, a diamond texture, or the like. The second lines can also be twill lines, Chinese character lines, diamond lines and the like.

In some embodiments, referring to fig. 4 and 5, the shaft 30 can be a long shaft, and the long shaft penetrates through the first shaft hole 22a, the second shaft hole 1221a and the base 221. The rotating shaft 30 may also be two short shafts, wherein one of the short shafts passes through one of the first shaft holes 22a and one side of the seat body 221 and extends into the second shaft hole 1221a, and the other short shaft passes through the other of the first shaft holes 22a and the other side of the seat body 221 and extends into the second shaft hole 1221 a.

In other embodiments, two short shafts may be connected to two opposite sides of the connecting plate 12, and the two short shafts respectively extend into the two first shaft holes 22a to pivotally connect the connecting plate 12 to the mounting seat 22.

In an embodiment, referring to fig. 11 and 16, a groove 121b is formed on an end surface of the first plate 121 facing the accommodating space 21a, the groove 121b extends along an axial direction of the rotating shaft 30, and a portion of the rotating shaft 30 is located in the groove 121 b. Thus, the distance between the end surface of the first plate 121 facing the accommodating space 21a and the rotating shaft 30 is reduced, so that the structure of the mounting seat 22 is more compact. In addition, the matching of the groove 121b and the rotating shaft 30 can also play a role in rotation guiding during the rotation of the connecting plate 12, so that the rotation process of the connecting plate 12 is more stable.

Specifically, the groove wall surface of the groove 121b is fitted to the outer surface of the rotating shaft 30. In other words, the shaft 30 is a cylinder, and the wall surface of the groove 121b is a curved surface adapted to the outer surface of the shaft 30.

In an embodiment, referring to fig. 13 to 18, the second plate 122 includes a boss 123 extending from the connecting portion 1221 toward the seat 221. The base 221 includes a top plate 2213 connected to the top end of the connecting rib 2212, the supporting rib 2211 and the top plate 2213 together define a rotation space 22b, along the height direction of the base 221, the rotating shaft 30 is located between the top plate 2213 and the supporting rib 2211, the boss 123 can rotate around the axis of the rotating shaft 30 in the rotation space 22b, the boss 123 abuts against the top plate 2213 to define the opening position of the cover shell 11, and the boss 123 abuts against the supporting rib 2211 to define the closing position of the cover shell 11. The stopper contacts the boss 123 through the support rib 2211 to define the closed position of the cover case 11, and the stopper contacts the boss 123 through the top plate 2213 to define the open position of the cover case 11. As such, not only the cover case 11 can be stably maintained at the closed position and the open position, but also the opening limit angle of the cover case 11 can be limited, for example, by controlling the inclination angle of the top plate 2213 or providing the recessed areas 2214a with different depths on the top plate 2213 to limit the opening angle of the cover case 11, for example, the opening angle may be 80 °, 90 °, 100 °, and the like, thereby facilitating the taking or placing of an article from the accommodating space 21 a.

In an embodiment, referring to fig. 16, a dimension of the connecting portion 1221 along the axial direction of the rotating shaft 30 is smaller than a dimension of the first plate 121 along the axial direction of the rotating shaft 30. With such a design, the connecting portion 1221 can be covered by the first plate 121.

In an embodiment, referring to fig. 16, a dimension of the boss 123 along the axial direction of the rotating shaft 30 is smaller than a dimension of the first plate 121 along the axial direction of the rotating shaft 30. The boss 123 can rotate in the rotating space 22b, and the interference of other structures of the seat body 221 with the movement of the boss 123 is avoided.

The opening groove 2213a provides an avoiding space for the connecting portion 1221, and prevents the connecting portion 1221 from interfering with the top plate 2213 in the rotating process, so that the connecting plate 12 has a large rotating amplitude.

In one embodiment, referring to fig. 12 to 14, the mounting seat 22 is an integrally formed structure. Therefore, the structural strength among the components of the mounting seat 22 is enhanced, and the process flow is saved. Of course, the mounting seat 22 may also be a split structure, and the components are connected, for example, welded.

In one embodiment, referring to fig. 15 to 16, the connecting plate 12 is an integrally formed structure. Therefore, the structural strength among the components of the connecting plate 12 is enhanced, and the process flow is saved. Of course, the connecting plate 12 may be a split structure, and the components are connected, for example, by welding.

The mounting seat 22 and the connecting plate 12 provided by the embodiment of the application can be made of metal materials, so that the texture is increased, the attractiveness is further improved, and the product expressive force is increased. Of course, the mounting block 22 and the connecting plate 12 may also be made of plastic in order to reduce weight. The material of the mounting seat 22 and the connecting plate 12 is not limited in the embodiments of the present application.

In an embodiment, referring to fig. 1 and fig. 2, when the cover shell 11 is located at the closed position, the outer surface of the housing 21, the surface of the seat 221 located in the first notch 21b, and the surface of the connecting plate 12 together form a smooth surface. That is to say, the seat body 221 located in the first notch 21b and the connecting plate 12 located in the first notch 21b do not protrude or fall below the outer surface of the housing 21, so that the design not only can improve the aesthetic appearance, but also is convenient for a user to feel a sharp corner or a protruding structure when gripping the housing 21, and has a better hand feeling.

In one embodiment, referring to fig. 4-5 and 17-20, the storage box includes an elastic member 40, the cover shell 11 has a threshold position between the closed position and the open position, and the elastic member 40 is loaded between the mounting seat 22 and the connecting plate 12. That is, for the elastic member 40, the mount 22 and the connection plate 12 are both loaded by the elastic member 40. In the state where the cover case 11 is located at the critical position, the moment applied to the cartridge cover 10 by the elastic member 40 is zero. When the cover case 11 is biased to either side of the critical position in the rotational direction, the elastic member 40 applies a driving torque to the cartridge cover 10 to drive the cover case 11 to move to the closed position or the open position.

It should be noted that the above-mentioned "when the cover shell 11 is biased to either side of the critical position in the rotation direction, the elastic member 40 applies a driving torque to the box cover 10 to drive the cover shell 11 to move to the closed position or the open position" includes two cases, the first case: when the cover case 11 deviates from the critical position and is located at a first side of the critical position in the rotation direction, the elastic member 40 drives the cover case 11 to move to the open position. And the second method comprises the following steps: when the cover case 11 deviates from the critical position and is located on the second side of the critical position in the rotational direction, the elastic member 40 drives the cover case 11 to move to the closed position.

Specifically, referring to fig. 19, the elastic member 40 applies a force F1 to the lid 10, the force F1 generates a first moment W1 about the axis (simplified to point O in fig. 19) of the rotating shaft 30, the first moment W1 is the above-mentioned driving moment, and the lid 11 moves to the closed position and is kept at the closed position under the action of the first moment W1, that is, the lid 11 does not deviate from the current closed position in the case that no external force acts or the action of the external force on the lid 10 is not enough to overcome the resistance formed by the first moment W1.

Referring to fig. 20, the elastic element 40 applies a force F2 to the box cover 10, the force F2 generates a second torque W2 about the axis of the rotating shaft 30 (simplified to point O in fig. 20), and the second torque W2 is the above-mentioned driving torque, wherein the first torque W1 and the second torque W2 are opposite in direction. The cover case 11 is moved to the open position by the second moment W2 and is maintained at the current open position, that is, the cover case 11 is not deviated from the current open position without an external force or without an external force acting on the cap 10 enough to overcome the resistance formed by the second moment W2.

When the cover 11 needs to be switched from the closed position to the open position, the user can rotate the lid 10 slowly, the force applied by the user needs to overcome the resistance generated by the first torque W1, that is, the first torque W1 is a resisting torque, after the cover 11 is rotated by an angle that enables the cover 11 to pass the above-mentioned critical position, the elastic member 40 applies a second torque W2 in the opposite direction to the lid 10, the direction of the second torque W2 is the same as the rotating direction, the second torque W2 is a driving torque, even if the user releases his hand, the cover 11 can automatically rotate by the elastic member 40 until reaching the open position, and is stably maintained at the open position by the second torque W2.

When the cover 11 needs to be switched from the open position to the closed position, the user can slowly rotate the lid 10 in the opposite direction, and the force applied by the user needs to overcome the resistance generated by the second torque W2, that is, the second torque W2 is a resisting torque, and after the lid 10 passes the above critical position due to the rotation angle of the cover 11, the elastic member 40 applies the first torque W1 in the opposite direction to the lid 10, so that even if the user looses his hand, the cover 11 can automatically continue to rotate to the closed position due to the elastic member 40, and can be stably maintained at the closed position due to the first torque W1.

That is to say, in certain rotation range, lid shell 11 has the function of automatic closure and automatic opening, and the closed process all has the damping to feel with opening the process, is favorable to promoting user's experience and feels.

In one embodiment, referring to fig. 21, the resilient member 40 includes at least one torsion spring 40'. The torsion spring 40' includes a first leg 41, a second leg 42 and a spiral body 43, the first leg 41 and the second leg 42 are connected to two opposite sides of the spiral body 43 in the axial direction, the first leg 41 is connected to the seat body 221, and the second leg 42 is connected to the connecting plate 12 to drive the cover shell 11 to rotate around the axis of the rotating shaft 30. That is, the second leg 42 of the torsion spring 40' can drive the cover case 11 to rotate in both the first direction about the axis of the rotary shaft 30 and the second direction about the axis of the rotary shaft 30. The first direction is opposite to the second direction. The included angle between the axis of the spiral body 43 and the axis of the rotating shaft 30 ranges from 45 degrees to 90 degrees. Thus, the space occupied by the torsion spring 40' in the axial direction perpendicular to the rotating shaft 30 can be reduced, so that the storage box is compact in structure.

Specifically, the screw 43 is suspended, that is, the screw 43 will follow the displacement of the second leg 42.

It is understood that the torsion spring 40' may form the first torque W1 in a compressed state or the first torque W1 in a stretched state. Similarly, the torsion spring 40' may form the second torque W2 in a compressed state or may form the second torque W2 in a stretched state. And are not intended to be limiting herein.

As the cover 11 rotates, the distance between the end of the first leg 41 and the end of the second leg 42 changes, which results in a change in the pitch of the screw 43, that is, the screw 43 elastically deforms in its axial direction, and thus the screw 43 has a resilient force in its axial direction. The resilient force acts on the lid 10 to form the above-mentioned forces F1 and F2. Since the acting forces F1 and F2 are relatively determined in the direction substantially along the axial direction of the spiral body 43, the diameter, material, pitch, etc. of the spiral body 43 can be easily designed in the process of designing the torsion spring 40'.

In one embodiment, the axis of the screw 43 is perpendicular to the axis of the shaft 30. That is, the axis of the screw 43 forms an angle of 90 ° with the axis of the rotating shaft 30. Since the torsion spring 40 ' relies on the acting force formed by the axial elastic deformation of the spiral body 43, even if the maximum distance between the end of the first leg 41 and the end of the second leg 42 is designed to be relatively small, the torsion spring 40 ' can apply a large elastic force to the box cover 10, and therefore, the occupied sizes of the torsion spring 40 ' in the height direction (up-down direction) and the width direction (left-right direction) of fig. 17 are relatively small, so that the storage box structure can be compact.

It is understood that the number of the torsion springs 40' may be one, or may be plural, wherein plural includes two or more. It should be noted that in the embodiment with a plurality of torsion springs 40 ', the plurality of torsion springs 40' may be spaced apart from each other, not interfere with each other, or may be connected to each other.

It should be noted that, in the embodiment with only one torsion spring 40', the first leg 41 and the second leg 42 both generate a force component in the axial direction of the rotating shaft 30, and the force component directions of the two are the same. The component force will force the box cover 10 to move along the axial direction of the rotating shaft 30, which will cause a sloshing and unstable feeling for the user. To this end, in an embodiment, please refer to fig. 4, 5 and 21, the number of the torsion springs 40 ' is two, the ends of the first legs 41 of the two torsion springs 40 ' are fixedly connected, and the axes of the spiral bodies 43 of the two torsion springs 40 ' are parallel. That is, the two torsion springs 40 'form a double torsion spring 40' design. On the one hand, two torsional spring 40's structural strength is high, and torsion is big, and stability is good, and non-deformable when atress is great, and long service life can promote the reliability and the durability of receiver. On the other hand, the two torsion springs 40' have opposite force components in the axial direction of the rotation shaft 30 and cancel each other out, so that the box cover 10 can be centered at the middle position along the axis of the rotation shaft 30. Specifically, due to manufacturing errors, assembly errors, and the like, a certain axial gap exists between the cover 10 and the mounting seat 22 along the axial direction of the rotating shaft 30, and the axial gap is not only required to ensure that the cover 10 and the mounting seat 22 can be assembled normally, but also required to cause a large dry friction between the cover 10 and the mounting seat 22. Due to the axial clearance, the box cover 10 has the possibility of axial movement. Under the action of the two torsion springs 40 ', when the box cover 10 is located at the middle position, the axial acting forces of the two torsion springs 40' are balanced, when the box cover 10 moves a little along the left side of fig. 21, the right torsion spring 40 'will force the box cover 10 to move to the right, and when the box cover 10 moves a little along the right side of fig. 21, the left torsion spring 40' will force the box cover 10 to move to the left, so reciprocating, and the box cover 10 is stabilized at the middle balanced position. Therefore, even if the box cover 10 has larger axial gaps along the two axial sides, the box cover 10 cannot move along the axial direction, the requirements on the manufacturing precision and the assembling precision of the box cover 10 and the mounting seat 22 can be reduced, and the reduction of the production cost is facilitated.

Specifically, in an embodiment of the present application, referring again to fig. 21, the first leg 41 and the second leg 42 are both of a bent structure, and the two torsion springs 40' substantially form a regular hexagon.

In an embodiment, referring to fig. 11 and 16, the connecting plate 12 is provided with insertion holes 12a at two opposite sides along the axial direction of the rotating shaft 30, wherein the end of the second leg 42 of one torsion spring 40 'is located in one of the insertion holes 12a, and the end of the second leg 42 of the other torsion spring 40' is located in the other insertion hole 12 a. During the rotation of the box cover 10 around the axis of the rotating shaft 30, the end of the second leg 42 of the torsion spring 40 'can rotate in the insertion hole 12a to improve the stress condition of the torsion spring 40'.

In an embodiment, referring to fig. 11 and 16, the two insertion holes 12a are located on the same straight line, and the line between the two insertion holes 12a is parallel to the axis of the rotation shaft 30.

In one embodiment, referring to fig. 11 and 16, the insertion holes 12a are formed on two opposite sides of the boss 123 along the axial direction of the rotating shaft 30. The dimension of the boss 123 in the axial direction of the rotation shaft 30 is smaller than the dimension of the first plate body 121 in the axial direction of the rotation shaft 30. In this manner, the distance between the ends of the second legs 42 of the two torsion springs 40 'is made smaller, facilitating the installation of the torsion springs 40'. Further, referring to fig. 12 and 13, an avoiding notch 2211b is provided at a position where the support rib 2211 abuts against the boss 123, and a portion of the boss 123 is located in the avoiding notch 2211b in a state where the cover case 11 is located at the closed position. So, not only can make effectively to cooperate between boss 123 and the brace rod 2211, can also make boss 123 along the ascending thickness of the axis direction of perpendicular to pivot 30 thicker, be convenient for set up spliced eye 12a on boss 123, avoid spliced eye 12 a's pore wall to be too thin.

In one embodiment, referring to fig. 12 and 13, the base 221 includes a bottom plate 2214 connected to the bottom ends of the connecting ribs 2212. The top surface of bottom plate 2214 is formed with a recessed area 2214 a. The base 221 further includes a stop 2215 located on the top side of the recessed area 2214a, the stop 2215 and the surface of the recessed area 2214a together define a limiting groove, and the first leg 41 of the torsion spring 40' is movably disposed in the limiting groove. That is, in this embodiment, during assembly, only the first leg 41 of the torsion spring 40' needs to be snapped into the retaining groove, and the stop sheet 2215 can prevent the first leg 41 from being separated from the top side of the recessed area 2214a from the bottom plate 2214.

In one embodiment, referring to fig. 7, the inner surface of the housing 21 is provided with a plug slot 20a, the seat body 221 can be inserted into the plug slot 20a from the top opening of the accommodating space 21a, and the seat body 221 is supported on the bottom wall of the plug slot 20 a.
