Alternatively, the bottom surface 1114 may be rectangular, circular, triangular, or other shape. In the following embodiments, the bottom 1114 is rectangular, and the side surface 1134 is disposed along the circumference of the bottom 1114 and forms a rectangular receiving cavity 115 with the bottom 1114.

Specifically, the first mounting portion 1112 and the second mounting portion 1132 are respectively disposed on the bottom surface 1114 and the side surface 1134, and the first engaging portion 121 and the second engaging portion 123 are disposed at two opposite ends of the key 120. When the first mounting portion 1112 is engaged with the first engaging portion 121 and the second mounting portion 1132 is engaged with the second engaging portion 123, the key 120 can be limited from the housing 110 at two opposite ends of the key 120, so as to mount the key 120 and the housing 110. When one of the key 120 or the housing 110 does not meet the processing requirement, the first mounting portion 1112 and the first mating portion 121, and the second mounting portion 1132 and the second mating portion 123 are detached, so that the key 120 and the housing 110 can be separated, and then the other of the key 120 or the housing 110 meeting the processing requirement can be reused, so as to reduce the waste in the production process of the key mounting structure 10.

In some embodiments, the first mounting portion 1112 is one of a retaining post or a retaining hole, and the first mating portion 121 is the other of a retaining post or a retaining hole.

Taking the first mounting portion 1112 as a limiting post and the first matching portion 121 as a limiting hole as an example, the limiting post protrudes from the bottom 1114 along the vertical direction, the limiting hole is formed on the side 1134 and penetrates through the sidewall 113, and the axis of the limiting hole extends vertically. When the key 120 is accommodated in the accommodating cavity 115, the operation limiting column penetrates through and is clamped in the limiting hole, so that the sliding of the key 120 in the horizontal plane is limited, and one end of the key 120 is conveniently and reliably connected with the shell 110. Moreover, the matching mode of the limiting hole and the limiting column is simple and easy to operate, which is convenient for improving the assembly efficiency of the key 120 and the shell 110.

The strip holes penetrate through the side surface 1134 of the sidewall 113, extend in a first direction perpendicular to the vertical direction and are parallel to the length direction of the bottom surface 1114, and the axis of each strip hole extends in a second direction perpendicular to the vertical direction and the first direction and is parallel to the width direction of the bottom surface 1114. The bar-shaped bosses protrude from the surface of the key 120 facing the side surface 1134 in the second direction. The bar boss operationally wears to locate the bar downthehole, and the outer wall of bar boss and the pore wall in bar hole are laminated mutually. Therefore, the sliding of the key 120 in the plane perpendicular to the second direction is limited, so that the other end of the key 120 is reliably connected to the housing 110.

In addition, the matching mode of the strip-shaped bosses and the strip-shaped holes is simple and easy to operate, and the assembly efficiency of the keys 120 and the shell 110 can be further improved.

In other embodiments, the second mounting portion 1132 and the second matching portion 123 may also be pin-hole matching, screw-hole matching, etc.

In some embodiments, the bottom wall 111 has a third mounting portion 1118, the key 120 has a third mating portion 125, and the third mating portion 125 removably mates with the third mounting portion 1118.

Specifically, the third mounting portion 1118 and the third mating portion 125 both extend along the second direction, the third mounting portion 1118 and the first mounting portion 1112 are disposed at the same end of the key 120, the third mounting portion 1118 and the third mating portion 125 are mated, and the sliding of the key 120 in a plane perpendicular to the second direction is further limited, so as to achieve reliable connection between one end of the key 120 and the housing 110. By integrating the first mounting portion 1112, the first matching portion 121, the second mounting portion 1132, the second matching portion 123, the third mounting portion 1118, and the third matching portion 125, the housing 110 can limit the sliding of the key 120 in multiple directions and multiple positions, thereby further improving the reliability of the mounting between the key 120 and the housing 110.

Specifically, the limiting of the key 120 is explained in detail herein. The first mounting portion 1112 is engaged with the first engaging portion 121 to limit the sliding of the key 120 in the first direction and the second direction, the second mounting portion 1132 is engaged with the second engaging portion 123 to limit the sliding of the key 120 in the vertical direction and the second direction, and the third mounting portion 1118 is engaged with the third engaging portion 125 to limit the displacement of the key 120 in the vertical direction and the second direction, so that the housing 110 can limit the degrees of freedom of the key 120 in multiple directions by combining the first mounting portion 1112 with the first engaging portion 121, the second mounting portion 1132 with the second engaging portion 123, the third mounting portion 1118 with the third engaging portion 125, so that the key 120 and the housing 110 have better installation reliability.

In some embodiments, the third mounting portion 1118 is either a capture hole or a capture arm and the third mating portion 125 is the other of a capture hole or a capture arm.

Taking the third mounting portion 1118 as a fastening hole and the third mating portion 125 as a fastening arm, the axes of the fastening arm and the fastening hole extend along the second direction. When the buckling arm penetrates through the buckling hole and the outer wall of the buckling arm is attached to the hole wall of the buckling hole, the sliding of the buckling arm in the plane perpendicular to the second direction can be further limited by the hole wall of the buckling hole, so that the reliability and firmness of the assembly of the key 120 and the housing 110 can be enhanced. In addition, the matching mode of the buckling holes and the buckling arms is simple and easy to operate, and the assembly efficiency of the key 120 and the shell 110 can be further improved.

Specifically installing button 120 in casing 110's in-process, can wear to locate the bar downthehole with the bar boss earlier, then operate spacing post and spacing hole cooperation to wear to locate the buckle downthehole with the buckle arm simultaneously, can realize button 120's installation.

It should be noted that, in other embodiments, the third mounting portion 1118 and the third mating portion 125 can also be a pin-through hole, a screw-through hole, or the like.

In some embodiments, the key 120 includes a first bending portion 127 and a second bending portion 129 intersecting with the first bending portion 127, the first bending portion 127 is disposed parallel to the sidewall 113, the second bending portion 129 is disposed parallel to the bottom wall 111, the first engaging portion 121 and the third engaging portion 125 are disposed on the second bending portion 129, and the second engaging portion 123 is disposed on the first bending portion 127.

Specifically, the first bending section 127 extends along the vertical direction and is disposed parallel to the side surface 1134, and the second bending section 129 extends along the second direction and is disposed parallel to the bottom surface 1114.

Therefore, when the first mounting portion 1112, the first mating portion 121, the second mounting portion 1132, the second mating portion 123, and the third mounting portion 1118 and the third mating portion 125 are mounted in a mating manner, the first bending section 127 can be supported by the side surface 1134, and the second bending section 129 can be supported by the bottom wall 111, so as to improve the limiting and supporting effect of the housing 110 on the key 120, and thus the key 120 can be mounted more reliably.

Specifically, the first bending section 127 and the second bending section 129 are both plate-shaped structures, and the first bending section 127 and the second bending section 129 both have a certain width in the first direction. The rib-shaped projection protrudes from the surface of the first bending section 127 facing the side surface 1134. And extends to both sides of the first bent section 127 in the first direction. The buckling arm and the two limiting holes are formed at one end of the second bending section 129 far away from the first bending section 127, the two limiting holes are distributed at two opposite sides of the second bending section 129 at intervals along the first direction, and the buckling arm protrudes out of one end face of the second bending section 129 far away from the first bending section 127 along the second direction.

The integrated strip-shaped holes and the limiting holes are arranged at two opposite ends of the key 120, the strip-shaped holes extend to two sides of the first bending section 127, the two limiting holes are distributed at two sides of the second bending section 129, the fastening arms protrude out of one end of the second bending section 129 far away from the first bending section 127, and the shell 110 can limit the positions of the two ends and two sides of the key 120, so that the key 120 has better installation reliability.

Optionally, the first bending section 127, the second bending section 129, the bar-shaped protrusion and the snap arm may be integrally formed or may be separately formed. It should be noted that in other embodiments, the key 120 may also be a straight plate structure.

In some embodiments, at least the second bending section 129 is an elastic structure, the second bending section 129 includes a first end surface adjacent to the first bending section 127 and a second end surface far away from the first bending section 127, and the second bending section 129 is provided with a plurality of strip notches 1292 spaced from the first end surface to the second end surface.

Optionally, the first bending section 127 is an elastic structure, or both the first bending section 127 and the second bending section 129 are elastic structures.

The bar-shaped notches 1292 are arranged at intervals along the direction from the first end face to the second end face, that is, the bar-shaped notches 1292 are arranged at intervals along the second direction. At the same time, each bar notch 1292 extends to one side of the second bend segment 129 along the first direction. Under the condition that second bending segment 129 itself has certain elasticity, the setting of a plurality of bar breach 1292 can strengthen the tensile ability of second bending segment 129, so after the bar boss wore to locate the bar through-hole, spacing post with second bending segment 129 jack-up and lead to spacing post can't align with spacing hole, and the buckle arm is difficult to wear to locate in the buckle hole. At this time, the second bending section 129 is stretched along the second direction, so that the limiting column can smoothly penetrate through the limiting hole, and the buckle arm can smoothly penetrate through the buckle hole, so as to facilitate the installation of the key 120.

Further, any two adjacent bar-shaped notches 1292 are arranged in a staggered manner.

Specifically, any two adjacent strip notches 1292 extend to two opposite sides of the second bending section 129. If any two adjacent strip notches 1292 extend to the same side of the second bend segment 129, then during the process of stretching the second bend segment 129, the pulling force will be concentrated on the other side of the second bend segment 129, which may cause the second bend segment 129 to break. And any two adjacent strip-shaped notches 1292 are arranged in a staggered manner, when the second bending section 129 is stretched, the pulling force can be uniformly dispersed to two sides of the second bending section 129, so as to prevent the second bending section 129 from being broken, and thus the key 120 key mounting structure 10 has better mounting reliability.

In some embodiments, the first bending section 127 is also an elastic member.

When a force is applied in the second direction from the side of the strip-shaped projection facing away from the first bending section 127, the first bending section 127 can be slightly bent relative to the second bending section 129. After the key 120 and the housing 110 are assembled, a trigger is further formed on one side of the first bending section 127 facing the second bending section 129, and the trigger and the first bending section 127 are spaced apart from each other. When the strip-shaped boss is pressed along the second direction, because the first bending section 127 is an elastic member, the first bending section 127 is deformed under stress and slightly bent relative to the second bending section 129, so that the first bending section 127 can be abutted against the trigger to trigger the charging or discharging of the battery cell. When the pressing is stopped, the first bent section 127 springs back to a state of abutting against the side surface 1134. Therefore, by arranging the first bending section 127 as an elastic member, on one hand, the first bending section 127 can be pressed in a pressing manner, so that the first bending section 127 can be slightly bent relative to the second bending section 129, and charging and discharging of the battery cell are realized. On the other hand, after the pressing operation is completed, the first bending section 127 can automatically return to the original state of abutting against the side surface 1134, so as to ensure the next normal operation of the key mounting structure 10. In addition, the elasticity of the first bending section 127 can make the first bending section 127 automatically rebound, so that the use of the triggering element in the charger can be reduced, the convenience of the operation of the whole key installation structure 10 can be improved, and the space utilization rate of the key installation structure 10 is higher compared with the situation that the resetting element is arranged in the accommodating cavity 115 to drive the first bending section 127 to complete and trigger the triggering element.

In some embodiments, the bottom wall 111 includes a bottom 1114 and a rib 1116 protruding from the bottom 1114, and the key 120 is supported on an end of the rib 1116 away from the bottom 1114. Specifically, the reinforcing rib 1116 protrudes from the bottom face 1114 and extends along the circumferential direction of the second bent section 129, and the second bent section 129 is supported at one end of the reinforcing rib 1116 away from the bottom face 1114. By providing the reinforcing rib 1116, on one hand, the second bending section 129 can be supported above the bottom 1114, so that an operator can conveniently clamp the second bending section 129 from two sides of the second bending section 129 and operate the second bending section 129 to stretch; on the other hand, the contact area between the second bending section 129 and the reinforcing rib 1116 is relatively small, so that the friction force applied to the second bending section 129 is also small in the process of stretching the second bending section 129 to slide along the second direction relative to the first bending section 127, and the abrasion of the second bending section 129 can be reduced.

It should be noted that, in some embodiments, the stiffener 1116, the bottom 1114, the first mounting portion 1112, and the third mounting portion 1118 may be integrally formed or may be separately formed. In some embodiments, the first and third mounting portions 1112, 1118 are disposed at an end of the reinforcement rib 1116 remote from the bottom surface 1114.
