[0037] On the second aspect, the present application also provides a battery box, including an adapter plate, which serves as a positive conductive part of the battery box, and the adapter plate cooperates with the positive pole of the battery. It also includes a negative conductive part whose inner end cooperates with the negative pole of the battery. The outer ends of the adapter plate and the negative conductive part cooperate with an external socket. The inner end of the negative conductive part is elastically set inward when at rest and has a protruding contact structure. The battery is inserted from front to back, and the positive and negative poles of the battery form multi-point contact with the corresponding abutment plates and the contact structure. A pressing part that cooperates with the inner end of the negative conductive part is also provided in the battery box.

[0038] The advantages of adopting the above technical solution are: as the battery is inserted, the positive pole of the battery forms a multi-point contact fit with the adapter piece on the inner end of the positive conductive part. At the same time, the negative pole of the battery forms a multi-point contact fit with the contact structure on the inner end of the negative conductive part, and the adapter piece and the contact structure are integrally formed on the corresponding positive conductive part and the negative conductive part. Compared with the method of adopting a conductive spring, it can effectively ensure the stable conduction of the positive and negative poles of the battery and the positive conductive part and the negative conductive part, and is less likely to have undervoltage problems. It is safer to use and is also easy to assemble. A pressing part that cooperates with the inner end of the negative conductive part is provided in the battery box. When the negative pole of the battery acts on the negative conductive part, the pressing part provides support force for the negative conductive part, thereby ensuring that the battery is not prone to vibration, so that the first contact structure and the second contact structure are in stable contact with the positive and negative poles of the battery.

[0039] Furthermore, the lower end of the pressing member is a plug-in end bent downward, and the upper end of the pressing member is a pressing end bent upward and inward, and the pressing end is located on the downward pressing path of the inner end of the negative electrode conductive member.

[0040] The advantages of adopting the above technical solution are: when the negative electrode of the battery acts on the negative conductive part, the pressing end provides support force for the negative conductive part, thereby ensuring that the battery is not prone to vibration, so that the first contact structure and the second contact structure are in stable contact with the positive and negative electrodes of the battery, and the pressing part adopts a structure of a plug-in end and a pressing end. Compared with the method of using a support spring, the pressing part can be assembled in the battery box through automation, which makes the assembly efficiency higher, facilitates assembly production, and the overall structural design is reasonable.

[0041] Furthermore, the pressing end is provided with a first horizontal section, the first horizontal section presses the second contact structure against the negative pole of the battery, the end of the first horizontal section is bent downward to form an inward limiting section, the head end of the first horizontal section is bent downward to form an elastic section, the end of the elastic section is bent horizontally inward to form a second horizontal section, and the plug-in end is bent and connected to the front side of the second horizontal section.

[0042] The advantages of adopting the above technical solution: by setting the first horizontal section, the second contact structure is pressed tightly against the negative pole of the battery. Compared with the inclined method, the pressing end will not hinder the downward pressure of the inner end of the negative conductive part. By setting the limiting section, when the battery is fully inserted, the limiting section and the inner wall of the battery box form a support, so that the pressing part has a better supporting effect. By setting the elastic section, the pressing end has better elasticity. By setting the second horizontal section and the plug-in end is bent and connected to the front side of the second horizontal section, this method of setting enables the pressing part to form a limiting fit with the support plate and the slot of the battery box, thereby realizing the position limitation of the pressing part and ensuring the stable use of the pressing part. The overall structure is reasonable and simple.

[0043] Furthermore, the head end of the first horizontal section is bent downward to continuously form a first bending portion and a second bending portion that are inclined and inward, the first bending portion and the second bending portion constitute the elastic section, and the angle A between the first bending portion and the first horizontal section is less than 30°.

[0044] The advantages of adopting the above technical solution are: the elastic section is composed of a first bending portion and a second bending portion, and the angle A between the first bending portion and the first horizontal section is less than 30°. Without taking up too much space, the elastic section has stronger elasticity and the structural design of the pressure member is more reasonable.

[0045] Furthermore, the pressure-resisting member is provided with an elastic notch and a bending notch, the elastic notch is used to divide the limiting section, the elastic notch extends to the root along the bending direction of the limiting section, the bending notch is used to bend the plug-in end, and the bending notch extends backward from the front end surface of the second horizontal section to the middle.

[0046] The advantages of adopting the above technical solution are: the setting of the elastic notch divides the limiting section into multiple parts, so that the limiting section has better elasticity, the pressure on the pressing part is more reasonable, and the formation of the bending notch makes the position of the plug-in end after bending close to the center line of the pressing part, so that the distance between the outer end of the positive conductive part and the outer end of the negative conductive part is appropriate, which is safer to use.

[0047] Furthermore, the battery box also includes an interlocking mounting shell and a main cover shell, a battery compartment for mounting the battery is provided in the mounting shell, the mounting shell is located on the left and right sides of the battery compartment and is respectively formed with at least a first card slot and at least a second card slot, the main cover shell is provided with a first card hook plate and a second card hook plate at corresponding positions, the first card slot is engaged with the first card hook plate, and the second card slot is engaged with the second card hook plate.

[0049] Furthermore, the first card slot is set through the side wall of the mounting shell, and an elastic pressing piece is slidably connected to the inside of the first card slot. A pressing block is connected to the surface of the elastic pressing piece opposite to the first hook plate. The pressing block is set corresponding to the hook of the first hook plate. Under the action of the elastic pressing piece, the pressing block releases the hook on the first hook plate from the first card slot.

[0050] The advantages of adopting the above technical solution are: by pressing the elastic pressing part, the pressure block inside it interacts with the hook on the first hook plate, causing the first hook plate to deform until the hook moves out of the first slot, and the engagement between the hook on the first hook plate and the first slot can be released, and the main cover shell can be removed from the mounting shell, thereby realizing battery replacement.

[0051] Furthermore, the elastic pressing part includes a pressing plate and a spring, and a sliding groove is formed on the left and right sides of the pressing plate. Slide blocks are correspondingly provided on the left and right inner wall surfaces of the first slot, and anti-slip blocks are formed on the edges of both sides of the inner wall surface of the pressing plate. One end of the spring is connected to the inner side of the pressing plate, and the other end of the spring is connected to the inner wall surface of the mounting shell.

[0052] The advantages of adopting the above technical solution are: the elastic pressing part is composed of a pressing plate and a spring, with a simple structure, and the cooperation of the slide groove and the slider makes the pressing action of the elastic pressing part more stable, the setting of the anti-falling block avoids the phenomenon of the elastic pressing part falling out, and the overall structure is reasonable.

[0054] The advantages of adopting the above technical solution are: by setting a structure in which a weak hook plate and an auxiliary slot are weakly engaged, and the weak hook plate and the first hook plate and the second hook plate are distributed up and down, it can assist the buckle connection between the main cover shell and the mounting shell without affecting the convenient disassembly of the main cover shell and the mounting shell, and the structure is more reasonable.

The battery box also includes a sub-cover shell that is covered at the front opening of the pin cavity, and the sub-cover shell is provided with fixing protrusions corresponding to the pin grooves.

[0056] The advantages of adopting the above technical solution are: by providing a pin cavity with a sub-cover shell at the lower end of the mounting shell, the outer ends of the positive conductive part and the negative conductive part will cooperate with the socket in the pin cavity, the power-on position will not be exposed to the outside world, and it is safer to use. In addition, pin grooves are provided on the mounting seat in the pin cavity and corresponding fixing protrusions are provided on the sub-cover shell, which realizes the limitation of the outer end position of the positive conductive part and the negative conductive part, and is simpler to install than the method of providing an additional mounting plate.

[0079] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0080] Referring to Figure 1, the inventors of this application discovered that during battery assembly, the end faces of the battery's electrodes (positive or negative) generally contact the adapter to achieve electrical connection. However, even after contact with the adapter, the battery electrodes are susceptible to shifting relative to the adapter, resulting in poor contact between the electrodes and the adapter. The embodiments of this application provide an electrical component that effectively prevents the electrical connector of an electrical component from shifting relative to the adapter, thereby improving the poor contact between the electrical connector and the adapter.

[0081] Please refer to FIG. 1 , which is a schematic diagram illustrating the separation of the adapter 100 and the battery 200 in an embodiment of the present application.

[0082] The electrical component is a battery box, a switch component, a remote control, an electric toothbrush, a shaver, a robot, an electric tool, etc. This embodiment is described using the electrical component being a battery box as an example. When the electrical component is a battery box, the electrical element is a battery 200, and the electrical connector of the electrical element is an electrode 210.

[0083] Please refer to FIG. 12 , the battery box includes an adapter plate 100 , a mounting shell 17 and a main cover shell 18 . The mounting shell 17 and the main cover shell 18 are connected to form a battery receiving chamber for receiving the battery 200 and the adapter plate 100 .

[0084] The battery accommodating cavity formed by the connection of the mounting shell 17 and the main cover shell 18 matches the shape of the battery 200, and the adapter plate 100 is arranged in the battery accommodating cavity. When the battery 200 is assembled in the battery accommodating cavity, the electrode 210 of the battery 200 cooperates with the adapter plate 100 to achieve electrical connection.

[0085] In this embodiment, the battery 200 is a cylindrical battery. Accordingly, the battery accommodating cavity formed by the connection of the mounting shell 17 and the main cover shell 18 is a cylindrical cavity, which is adapted to the shape of the battery 200; a base plate is provided on the main cover shell 18, and the adapter plate 100 is provided on the base plate. The connection method between the adapter plate 100 and the base plate includes but is not limited to snapping, welding, bonding or connection through fasteners such as bolts, and the connection method between the mounting shell 17 and the main cover shell 18 includes but is not limited to snapping, hinged, sliding connection or connection through fasteners such as bolts.

[0086] In other embodiments, the battery 200 is a square battery, and accordingly, the battery accommodating cavity formed by the connection of the mounting shell 17 and the main cover shell 18 is a square cavity. Of course, the battery 200 can also be in other shapes besides cylindrical batteries and square batteries, as long as the battery 200 matches the shape of the battery accommodating cavity.

[0087] Please refer to Figures 2 and 3. Figure 2 is a structural schematic diagram of the adapter plate 100 in the first perspective in the embodiment of the present application; Figure 3 is a structural schematic diagram of the adapter plate 100 in the second perspective in the embodiment of the present application.

[0088] The adapter 100 provided in the embodiment of the present application is used to fix the electrode 210 of the battery 200. The adapter 100 includes an adapter body 110, an abutting piece 120 and a first contact structure 3, wherein the first contact structure 3 includes an entrance limiting piece 130 and a head limiting piece 140; the abutting piece 120 is connected to the adapter body 110 and is used to abut against the end face of the electrode 210 of the battery 200 to achieve electrical connection; the number of the entrance limiting pieces 130 is at least two, and all the entrance limiting pieces 130 and the head limiting pieces 140 are connected to the adapter body 110, and the two oppositely spaced entrance limiting pieces 130 are connected. An opening 150 is formed between the entrance limit plates 130 for the electrode 210 to enter laterally, and the head limit plate 140 and the two entrance limit plates 130 spaced opposite to each other are distributed around the abutment plate 120; wherein, the two entrance limit plates 130 spaced opposite to each other are used to guide and avoid the electrode 210 in the process of the electrode 210 passing through the opening 150, and to limit and block the tail side of the electrode 210 when the electrode 210 passes through the opening 150, the end face of the electrode 210 abuts against the abutment plate 120 and the head side of the electrode 210 abuts against the head limit plate 140.

[0089] This embodiment is described using the battery 200 as a cylindrical battery. The electrode 210 of the cylindrical battery is cylindrical and protrudes from one end of the battery 200, so that the electrode 210 has perpendicular end faces and side faces; the head side face of the electrode 210 refers to the side face of the electrode 210 facing the head limiting plate 140, and the tail side face of the electrode 210 refers to the side face of the electrode 210 facing away from the head limiting plate 140.

[0090] It is understandable that, in other embodiments, the battery 200 may also be a square battery, and accordingly, the electrode 210 of the square battery is a rectangular body.

[0091] This embodiment is described with the number of entrance limit plates 130 being two, and an opening 150 for the electrode 210 to enter laterally is formed between the two entrance limit plates 130. The two entrance limit plates 130 are symmetrically arranged on both sides of the center line L of the opening 150. The head limit plate 140 and the two entrance limit plates 130 are distributed around the abutment plate 120 to form multi-point limitations on the side of the electrode 210.

[0092] It can be understood that in other embodiments, the number of entrance limit plates 130 can also be an even number such as four or six. For example, when the number of entrance limit plates 130 is four, the four entrance limit plates 130 are symmetrically arranged in pairs on both sides of the center line L of the opening 150, wherein the two entrance limit plates 130 close to the outside of the opening 150 are used to guide the electrode 210, and the two entrance limit plates 130 close to the inside of the opening 150 are used to guide and limit the electrode 210.

[0093] In the process of the electrode 210 passing through the opening 150, the two entrance limit plates 130 guide and avoid the electrode 210, and when the electrode 210 passes through the opening 150, the end face of the electrode 210 abuts against the abutting piece 120 and the head side of the electrode 210 abuts against the head limit plate 140, the two entrance limit plates 130 limit and block the tail side of the electrode 210. The two entrance limit plates 130 and the head limit plate 140 form multi-point limits on the side of the electrode 210, which can better prevent the electrode 210 from deviating relative to the adapter plate 100, so that the end face of the electrode 210 always abuts against the abutting piece 120, thereby improving the poor contact between the electrode 210 and the adapter plate 100.

[0094] Please refer to FIG. 4 , which is a schematic structural diagram of the entrance limiting piece 130 in an embodiment of the present application.

[0095] In this embodiment, the entrance limiting plate 130 includes a first connecting part 131, a first elastic part 132 and a first limiting part 133 which are connected in sequence toward the head limiting plate 140. The first connecting part 131 is connected to the adapter plate body 110, and the first elastic part 132 and the first limiting part 133 are both spaced apart and movable from the adapter plate body 110; the first connecting part 131 is used to guide the electrode 210 entering laterally; the first limiting part 133 is used to avoid the electrode 210 under the action of the first elastic part 132 during the process of the electrode 210 passing through the opening 150, and is used to limit and block the tail side of the electrode 210 when the electrode 210 passes through the opening 150, the end face of the electrode 210 abuts against the abutting plate 120 and the head side of the electrode 210 abuts against the head limiting plate 140.

[0096] The adapter plate 100 has a symmetrical structure along the center line L of the opening 150. The two first connecting parts 131 are respectively connected to the edges of the adapter plate body 110 located on both sides of the center line of the opening 150. There is a gap between the first elastic part 132 and the first limiting part 133 and the adapter plate body 110, so that the first elastic part 132 and the first limiting part 133 can move relative to the adapter plate body 110.

[0097] The extension direction of the first connection portion 131 on the plane parallel to the adapter plate body 110 is inclined relative to the extension direction of the center line L of the opening 150, and the distance between the ends of the two first connection portions 131 away from the head limiting plate 140 is greater than the distance between the ends of the two first connection portions 131 close to the head limiting plate 140, so that the two first connection portions 131 guide the electrode 210 when the electrode 210 moves along the center line L of the opening 150 toward the head limiting plate 140.

[0098] Please refer to FIG. 5 , which is a first front view of the adapter 100 in the embodiment of the present application.

[0099] In this embodiment, an included angle θ1 between the extending direction of the first connection portion 131 and the center line L of the opening 150 is 14-20°.

[0100] The angle θ1 between the extension direction of any first connection part 131 on the plane parallel to the adapter body 110 and the center line L direction of the opening 150 is 14-20°. Optionally, the angle θ1 is 14°, 17° or 20°, which can be selected within the above range according to actual working conditions; when the angle θ1 is within the range of 14-20°, the two first connection parts 131 can play a better guiding role for the electrode 210. When the first connection part 131 guides the electrode 210, it is not easy to generate a large friction force between the electrode 210 and the electrode 210, reducing the wear between the first connection part 131 and the electrode 210, so that the electrode 210 can pass through the opening 150 more smoothly and abut against the first limiting part 133; if the angle is too small, it will cause a large friction force to be generated between the first connection part 131 and the electrode 210, which is not conducive to the electrode 210 passing through the opening 150; if the angle is too large, it will not play a good guiding role for the electrode 210.

[0101] After the two first connecting parts 131 guide the electrode 210, the side of the head of the electrode 210 abuts against the part of the first limiting part 133 close to the first elastic part 132, pushing the two first limiting parts 133 to move outside the adapter body 110. At this time, the first elastic part 132 is deformed, and the first limiting part 133 avoids the electrode 210 when the first elastic part 132 is deformed; and the electrode 210 passes through the opening 150, the end face of the electrode 210 abuts against the abutting piece 120 and the side of the head of the electrode 210 When abutting against the head limiting plate 140, the first limiting portion 133 moves toward the inside of the adapter plate body 110 under the resetting action of the first elastic portion 132 until the part of the first limiting portion 133 away from the first elastic portion 132 abuts against the tail side of the electrode 210. At this time, since the elastic force of the first elastic portion 132 always exists, the elastic force generated by the two first elastic portions 132 acts on the tail side of the electrode 210 through the two first limiting portions 133, making it difficult for the electrode 210 to fall out from one side of the opening 150.

[0102] In this embodiment, the first limiting portion 133 and the first elastic portion 132 are both arc-shaped. The first limiting portion 133 is convex toward the opening 150 , and the first elastic portion 132 is concave toward the opening 150 .

[0103] It should be noted that the surface of the first limiting portion 133 facing the opening 150 is a convex surface, and the surface of the first elastic portion 132 facing the opening 150 is a concave surface.

[0104] In other embodiments, the first limiting portion 133 and the first elastic portion 132 are both linear, or one of the first limiting portion 133 and the first elastic portion 132 is linear and the other is arc-shaped.

[0105] Please refer to FIG. 6 , which is a schematic diagram of a partial structure of the head limiting piece 140 in an embodiment of the present application.

[0106] In this embodiment, the head limiting plate 140 includes a second connecting portion 141, a second elastic portion 142 and a second limiting portion 143 connected in sequence, the second connecting portion 141 is connected to the adapter plate body 110, and the second elastic portion 142 and the second limiting portion 143 are movable at intervals from the adapter plate body 110; the second limiting portion 143 is used to move back to the abutting plate 120 under the elastic action of the second elastic portion 142 after being abutted by the head side of the electrode 210, and under the resetting action of the second elastic portion 142, it and the first limiting portion 133 are respectively abutted on the head side and the tail side of the electrode 210, thereby jointly clamping the electrode 210; wherein, when the adapter plate 100 is in the reset state, the first limiting portion 133 and the second limiting portion 143 define an inscribed circle representing the clamped electrode 210.

[0107] The adapter body 110 has a relative head and tail, the second connecting portion 141 is connected to the head of the adapter body 110, and the opening 150 is located at the tail of the adapter body 110; the second elastic portion 142 and the second limiting portion 143 both have a gap with the adapter body 110, so that the second elastic portion 142 and the second limiting portion 143 can move relative to the adapter body 110.

[0108] The side surface of the head of the electrode 210 can abut against the second limiting portion 143 and push the second limiting portion 143 to move toward the outside of the adapter body 110. At this time, the second elastic portion 142 is deformed, which has a certain buffering effect on the insertion of the electrode 210. In addition, under the reset action of the second elastic portion 142, the second limiting portion 143 always abuts against the side surface of the head of the electrode 210, and the first limiting portion 133 always abuts against the side surface of the tail of the electrode 210. The second limiting portion 143 and the first limiting portion 133 cooperate to clamp the side surface of the electrode 210.

[0109] When the adapter plate 100 is in the reset state, the first limiting portion 133 and the second limiting portion 143 are both in the initial position, and the first elastic portion 132 and the second elastic portion 142 are not deformed. At this time, the first limiting portion 133 and the second limiting portion 143 jointly define an inscribed circle representing the clamping electrode 210.

[0110] In this embodiment, the second elastic portion 142 and the second limiting portion 143 are symmetrically distributed on both sides of the second connecting portion 141 .

[0111] The second connection portion 141 extends in a plane parallel to the adapter body 110 along the direction of the center line L of the opening 150. Both ends of the second connection portion 141 are connected to the second elastic portion 142 and the second limiting portion 143 in sequence. The second elastic portion 142 and the second limiting portion 143 at both ends of the second connection portion 141 are symmetrically arranged along the center line L of the opening 150.

[0112] When the side of the head of the electrode 210 abuts against the head limiting plate 140, the two second limiting parts 143 abut against the side of the head of the electrode 210 under the resetting action of the second elastic parts 142 connected to each of them. The two second limiting parts 143 cooperate with the two first limiting parts 133 to form a four-point limit on the side of the electrode 210, preventing the electrode 210 from deviating along the center line L of the opening 150, thereby improving the stability of the electrode 210.

[0113] In other embodiments, the second connecting portion 141 is only provided with the second elastic portion 142 and the second limiting portion 143 on one side. For example, the second connecting portion 141 is provided on one side of the center line of the opening 150, and the second connecting portion 141, the second elastic portion 142 and the second limiting portion 143 are connected in sequence. The portion of the second limiting portion 143 that abuts the side of the head of the electrode 210 is located on the center line L of the opening 150. At this time, the second limiting portion 143 cooperates with the two first limiting portions 133 to form a three-point limit on the side of the electrode 210, which can also prevent the electrode 210 from deviating along the center line L of the opening 150, thereby improving the stability of the electrode 210.

[0114] In this embodiment, the second elastic portion 142 and the second limiting portion 143 are both arc-shaped. The second limiting portion 143 is convex toward the inner side of the adapter body 110 , and the second elastic portion 142 is concave toward the inner side of the adapter body 110 .

[0115] It should be noted that the surface of the second limiting portion 143 facing the inner side of the adapter body 110 is a convex surface, and the surface of the second elastic portion 142 facing the inner side of the adapter body 110 is a concave surface.

[0116] In other embodiments, the second limiting portion 143 and the second elastic portion 142 are both linear, or one of the second limiting portion 143 and the second elastic portion 142 is linear and the other is arc-shaped.

[0117] Please refer to FIG. 9 , which is a second front view of the adapter 100 in the embodiment of the present application.

[0118] In this embodiment, the ratio of the radius R0 of the inscribed circle to the radius R1 of the first limiting portion 133 is (3-3.2):1, and the ratio of the radius R0 of the inscribed circle to the radius R2 of the first elastic portion 132 is (2.9-3.1):1.

[0119] Under the above-mentioned radius ratio, the radius R2 of the first elastic part 132 is greater than the radius R1 of the first limiting part 133, so that the first elastic part 132 is easy to deform when the electrode 210 pushes the first limiting part 133 toward the outside of the adapter plate body 110. When the two first limiting parts 133 cooperate with the two second limiting parts 143 to jointly support the side of the electrode 210, the resetting effect of the two first elastic parts 132 jointly gives the electrode 210 a force to move toward the head limiting plate 140, thereby making it difficult for the electrode 210 to detach from the opening 150.

[0120] For example, the ratio of the radius R0 of the inscribed circle to the radius R1 of the first limiting portion 133 is 3:1, 3.1:1 or 3.2:1, and the ratio of the radius R0 of the inscribed circle to the radius R2 of the first elastic portion 132 is 2.9:1, 3:1 or 3.1:1. It can be understood that the ratio of the radius R0 of the inscribed circle to the radius R1 of the first limiting portion 133 and the ratio of the radius R0 of the inscribed circle to the radius R2 of the first elastic portion 132 can be selected within the above range according to actual working conditions.

[0121] In this embodiment, the ratio of the radius R0 of the inscribed circle to the radius R3 of the second limiting portion 143 is (3-3.2):1, and the ratio of the radius R0 of the inscribed circle to the radius R4 of the second elastic portion 142 is (2.9-3.1):1.

[0122] Under the above-mentioned radius ratio, the radius R4 of the second elastic part 142 is greater than the radius R3 of the second limiting part 143, so that the second elastic part 142 is easy to deform when the electrode 210 pushes the second limiting part 143 toward the outside of the adapter plate body 110, thereby playing a better buffering role, and it is not easy to wear between the second limiting part 143 and the electrode 210; and when the two first limiting parts 133 cooperate with the two second limiting parts 143 to jointly support the side of the electrode 210, the resetting effect of the two second elastic parts 142 jointly gives the electrode 210 a force to move away from the head limiting plate 140, which balances the force given to the electrode 210 by the two first elastic parts 132, thereby enabling the electrode 210 to be stably clamped between the first limiting part 133 and the second limiting part 143.

[0123] For example, the ratio of the radius R0 of the inscribed circle to the radius R3 of the second limiting portion 143 is 3:1, 3.1:1 or 3.2:1, and the ratio of the radius R0 of the inscribed circle to the radius R4 of the second elastic portion 142 is 2.9:1, 3:1 or 3.1:1. It can be understood that the ratio of the radius R0 of the inscribed circle to the radius R3 of the second limiting portion 143 and the ratio of the radius R0 of the inscribed circle to the radius R4 of the second elastic portion 142 can be selected within the above range according to actual working conditions.

[0124] Please refer to FIG. 10 , which is a third front view of the adapter 100 in the embodiment of the present application.

[0125] The angle between the line connecting the center of the first limiting portion 133 on one side of the center line L of the opening 150 and the center of the inscribed circle and the line connecting the center of the second limiting portion 143 on the other side of the center line L of the opening 150 and the center of the inscribed circle is 13-15°; the angle between the line connecting the center of the second limiting portion 143 on one side of the center line L of the opening 150 and the center of the inscribed circle and the line connecting the center of the first limiting portion 133 on the other side of the center line L of the opening 150 and the center of the inscribed circle is 13-15°.

[0126] In this embodiment, the angle θ2 between the line connecting the center of the first limiting portion 133 above the center line L of the opening 150 and the center of the inscribed circle and the line connecting the center of the second limiting portion 143 below the center line L of the opening 150 and the center of the inscribed circle is 13-15°, and the angle θ3 between the line connecting the center of the second limiting portion 143 above the center line L of the opening 150 and the center of the inscribed circle and the line connecting the center of the first limiting portion 133 below the center line L of the opening 150 and the center of the inscribed circle is 13-15°.

[0127] By limiting the angle range between the line connecting the center of the first limiting portion 133 on one side of the center line L of the opening 150 and the center of the inscribed circle and the line connecting the center of the second limiting portion 143 on the other side of the center line L of the opening 150 and the center of the inscribed circle, and the angle range between the line connecting the center of the second limiting portion 143 on one side of the center line L of the opening 150 and the center of the inscribed circle and the line connecting the center of the first limiting portion 133 on the other side of the center line L of the opening 150 and the center of the inscribed circle, the two angle ranges are consistent, so that the forces exerted on the electrode 210 by the two first limiting portions 133 and the forces exerted on the electrode 210 by the two second limiting portions 143 are balanced, so that the electrode 210 is clamped more stably between the first limiting portion 133 and the second limiting portion 143.

[0128] For example, the angle between the line connecting the center of the first limiting portion 133 on one side of the center line L of the opening 150 and the center of the inscribed circle and the line connecting the center of the second limiting portion 143 on the other side of the center line L of the opening 150 and the center of the inscribed circle is 13°, 14° or 15°, and the angle between the line connecting the center of the second limiting portion 143 on one side of the center line L of the opening 150 and the center of the inscribed circle and the line connecting the center of the first limiting portion 133 on the other side of the center line L of the opening 150 and the center of the inscribed circle is 13°, 14° or 15°; it can be understood that the sizes of the two angles can be selected within the above-mentioned angle range according to the actual working conditions, as long as the sizes of the two angles are equal.

[0129] The line connecting the center of the first limiting portion 133 on one side of the center line L of the opening 150 and the center of the inscribed circle is tangent to the second limiting portion 143 on the other side of the center line L of the opening 150; the line connecting the center of the second limiting portion 143 on one side of the center line L of the opening 150 and the center of the inscribed circle is tangent to the first limiting portion 133 on the other side of the center line L of the opening 150.

[0130] By limiting the connection between the center of the first limiting portion 133 on one side of the center line L of the opening 150 and the center of the inscribed circle, the line is tangent to the second limiting portion 143 on the other side of the center line L of the opening 150, and the connection between the center of the second limiting portion 143 on one side of the center line L of the opening 150 and the center of the inscribed circle is tangent to the first limiting portion 133 on the other side of the center line L of the opening 150. When the two first limiting portions 133 and the two second limiting portions 143 jointly limit the electrode 210, any one of the two first limiting portions 133 and the two second limiting portions 143 is in line contact with the side surface of the electrode 210. At this time, it can not only play the role of multi-point limiting for the electrode 210, but also is not easy to cause wear on the side surface of the electrode 210, thereby ensuring the service life of the electrode 210.

[0131] In this embodiment, the diameter of the inscribed circle is smaller than the diameter of the electrode 210 .

[0132] When the diameter of the inscribed circle is smaller than the diameter of the electrode 210 , the two first limiting portions 133 are simultaneously interference fit with the tail side of the electrode 210 , and the two second limiting portions 143 are simultaneously interference fit with the head side of the electrode 210 , which provides a better clamping effect on the electrode 210 .

[0133] Exemplarily, the diameter of the inscribed circle is 3.6-4.0 mm, and correspondingly, the diameter of the electrode 210 is 4.1-4.5 mm. The diameter of the inscribed circle is smaller than the diameter of the electrode 210, so that the two first limiting portions 133 and the two second limiting portions 143 are simultaneously interference fit with the side of the electrode 210, giving the side of the electrode 210 a suitable clamping force, which is not easy to damage the electrode 210 and can also provide a better clamping effect on the electrode 210.

[0134] It is understandable that the diameter of the inscribed circle is merely an exemplary description. In actual applications, the diameter of the inscribed circle can be adaptively adjusted according to the diameter of the electrode 210 , as long as the diameter of the inscribed circle is smaller than the diameter of the electrode 210 .

[0135] There are multiple first elastic parts 132, the multiple first elastic parts 132 are connected in sequence, and the two first elastic parts 132 located at both ends of the multiple first elastic parts 132 are respectively connected to the first limiting part 133 and the first connecting part 131; and / or, there are multiple second elastic parts 142, the multiple second elastic parts 142 are connected in sequence, and the two second elastic parts 142 located at both ends of the multiple second elastic parts 142 are respectively connected to the second limiting part 143 and the second connecting part 141.

[0136] In this embodiment, there is one first elastic portion 132, and the two ends of the first elastic portion 132 are respectively connected to the first limiting portion 133 and the first connecting portion 131; there are two second elastic portions 142, and the two second elastic portions 142 are connected in sequence, with one second elastic portion 142 connected to the second limiting portion 143, and the other second elastic portion 142 connected to the second connecting portion 141.

[0137] In other embodiments, there are multiple first elastic portions 132, and two first elastic portions 132 located at both ends of the multiple first elastic portions 132 are respectively connected to the first limiting portion 133 and the first connecting portion 131, and there is one second elastic portion 142, and the two ends of the second elastic portion 142 are respectively connected to the second limiting portion 143 and the second connecting portion 141; or, there are multiple first elastic portions 132, and two first elastic portions 132 located at both ends of the multiple first elastic portions 132 are respectively connected to the first limiting portion 133 and the first connecting portion 131, and there are multiple second elastic portions 142, and two second elastic portions 142 located at both ends of the multiple second elastic portions 142 are respectively connected to the second limiting portion 143 and the second connecting portion 141.

[0138] In actual applications, the number of the first elastic part 132 and the second elastic part 142 can be determined according to the actual working conditions, as long as the first limiting part 133 provides appropriate clamping force to the side of the electrode 210 under the reset action of the first elastic part 132 and the second limiting part 143 provides appropriate clamping force under the reset action of the second elastic part 142.

[0139] In this embodiment, the first connection portion 131 and the second connection portion 141 are both vertically connected to the adapter body 110 .

[0140] The first connecting portion 131 and the second connecting portion 141 are both vertically connected to the adapter body 110, so that the first elastic portion 132, the first limiting portion 133, the second elastic portion 142 and the second limiting portion 143 are all perpendicular to the adapter body 110. When the electrode 210 passes through the opening 150, the first limiting portion 133 and the second limiting portion 143 simultaneously abut against the side of the electrode 210, and the abutting piece 120 abuts against the end face of the electrode 210.

[0141] In this embodiment, the adapter body 110 , the abutting piece 120 , the entrance limiting piece 130 and the head limiting piece 140 are integrally formed, and the first connecting portion 131 and the second connecting portion 141 are both bent relative to the adapter body 110 .

[0142] The first connection portion 131 and the second connection portion 141 are both bent 110° relative to the adapter body. The entrance limiting plate 130 is integrally formed with the adapter body 110 through the first connection portion 131, and the head limiting plate 140 is integrally formed with the adapter body 110 through the second connection portion 141, so that the overall stability of the adapter 100 is better.

[0143] In other embodiments, the first connection portion 131 and the second connection portion 141 are simultaneously plugged into the adapter body 110 , or the first connection portion 131 and the second connection portion 141 are simultaneously connected to the adapter body 110 via fasteners such as screws.

[0144] As another embodiment, the adapter plate can also design the first contact structure 3 to be a convex body formed by punching from the upper side to the lower side of the inner end of the adapter plate 100 by a punch, and the inner walls on both sides of the convex body are inclined inward from the front to the back. The first contact structure 3 can be formed by punching the inner end of the adapter plate 100 with a punch of a special shape. The forming method of the first contact structure 3 is simple and convenient. At the same time, the interior of the convex body formed by punching is a cavity structure, and the inner walls on both sides of the convex body corresponding to the cavity structure are inclined inward from the front to the back. With this special structure, the first contact structure 3 will gradually come into contact with the positive side wall of the battery as the positive pole of the battery is inserted, and cause it to deform to a certain extent. After the battery is installed in place, the positive pole of the battery located in the first contact structure 3 will be under the action of the clamping force generated by the deformation, and better multi-point contact with the inner wall of the first contact structure 3 is achieved, thereby achieving the purpose of better preventing the occurrence of intermittent poor contact.

[0145] Of course, the first contact structure 3 can also be an arc-shaped sheet with a hollow portion on the inner end of the adapter sheet 100. The arc-shaped sheet is formed by bending the inner periphery of the hollow portion in the same direction. In more detail, there are notches at the roots of the two ends of the arc-shaped sheet. The formation of the notch enables the subsequent bending process to be carried out effectively, and the overall structure is more reasonable. At the same time, the inner walls on both sides of the arc-shaped sheet are also inclined inward from front to back. In this way, the first contact structure 3 will gradually come into contact with the positive side wall of the battery as the positive pole of the battery is inserted, and cause it to deform to a certain extent. After the battery is inserted into place, the positive pole of the battery will maintain better multi-point contact with the inner wall of the first contact structure 3 under the clamping force generated by the deformation, thereby achieving the purpose of better preventing the occurrence of intermittent poor contact. At the same time, the formation of the hollow portion has lower requirements on the ductility of the inner end of the positive conductor, and no processing cracking will occur, and the product production efficiency is higher.

[0146] In more detail, the first contact structure 3 can also be composed of a first bent sheet, a second bent sheet, and a third bent sheet that are spaced apart on the inner periphery of the hollow portion and bent in the same direction, wherein the second bent sheet is located on the rear side of the first bent sheet and the third bent sheet, and the first bent sheet and the third bent sheet are respectively located on both sides of the second bent sheet. That is to say, such a structure reduces the ductility performance requirements of the inner end of the positive conductor, and also reduces the bending stress during bending, making the bending process easier to carry out and not easy to recover the deformation after bending. The structure is reasonable, and the first bent sheet and the third bent sheet are also inclined inward from front to back. In this way, as the positive pole of the battery is inserted, the positive pole of the battery will maintain better multi-point contact with the inner wall of the first contact structure 3 under the clamping force generated by the deformation, thereby achieving the purpose of better preventing the occurrence of intermittent poor contact.

[0147] In this embodiment, the abutment piece 120 is an elastic abutment piece, and the abutment piece 120 has a relative fixed end 121 and a free end 122. The fixed end 121 is connected to the adapter piece body 110. The fixed end 121 is closer to the opening 150 than the free end 122. The free end 122 is spaced apart from the adapter piece body 110. The free end 122 is used to abut against the end face of the electrode 210 to achieve electrical connection.

[0148] The extension direction of the abutment piece 120 is inclined relative to the adapter piece body 110. In the process of the electrode 210 passing through the opening 150 until the side of the head of the electrode 210 abuts against the second limiting portion 143, the end face of the electrode 210 presses down the free end 122 of the abutment piece 120, so that the free end 122 of the abutment piece 120 gradually approaches the adapter piece body 110. The angle between the abutment piece 120 and the adapter piece body 110 becomes smaller, causing the abutment piece 120 to deform. The resetting effect of the abutment piece 120 makes the free end 122 of the abutment piece 120 always abut against the end face of the electrode 210, thereby ensuring the stability of the electrical connection.

[0149] Optionally, there are multiple abutting pieces 120 , and multiple free ends 122 are simultaneously used to abut against the end surface of the electrode 210 to achieve electrical connection.

[0150] In this embodiment, there are two abutment pieces 120, and the extension directions of the two abutment pieces 120 are consistent. In the process of the electrode 210 passing through the opening 150 until the side of the head of the electrode 210 abuts against the second limiting portion 143, the free ends 122 of the two abutment pieces 120 simultaneously abut against the end face of the electrode 210, and always maintain two-point contact between the end face of the electrode 210, further improving the stability of the electrical connection and reducing the probability of electrical connection failure.

[0151] It is understandable that the number of abutment sheets 120 can be more than three, and the extension directions of the multiple abutment sheets 120 can be different, as long as the free ends 122 of the multiple abutment sheets 120 can abut the end faces of the electrode 210 at the same time and always maintain multi-point contact with the end faces of the electrode 210.

[0152] In this embodiment, a through hole 111 is defined in the adapter body 110. The fixed end 121 is connected to the inner sidewall of the through hole 111, and the free end 122 extends away from the adapter body 110. The through hole 111 is rectangular in shape. The fixed ends 121 of the two abutting pieces 120 are both connected to the inner sidewall of the through hole 111 near the opening 150. The free ends 122 of the two abutting pieces 120 extend toward the head stopper 140 and away from the adapter body 110. By arranging the abutting pieces 120 in the through hole 111, on the one hand, the abutting pieces 120 can be easily deformed and less likely to hinder the electrode 210 from passing through the opening 150. On the other hand, the reset action of the abutting piece 120 after deformation ensures that the free end 122 of the abutting piece 120 always abuts against the end face of the electrode 210.

[0153] In other embodiments, the shape of the through hole 111 may also be circular, trapezoidal or other polygonal shapes.

[0154] The battery box of this embodiment also includes a negative conductive part 2 whose inner end cooperates with the negative pole of the battery, and the outer ends of the adapter 100 and the negative conductive part 2 cooperate with the external socket. When the inner end of the negative conductive part 2 is at rest, it is elastically set inward and has a protruding second contact structure 4. The battery is inserted from front to back, and the positive and negative poles of the battery form multi-point contact with the corresponding first contact structure 3 and the second contact structure 4. As the battery is inserted, the positive pole of the battery forms a multi-point contact with the first contact structure 3 on the inner end of the adapter 100. At the same time, the negative pole of the battery also forms a multi-point contact with the second contact structure 4 on the inner end of the negative conductive part 2, and the first contact structure 3 and the second contact structure 4 are integrally formed on the corresponding adapter 100 and the negative conductive part 2. Compared with the method of using a conductive spring, it can effectively ensure the stable conduction between the positive and negative poles of the battery and the adapter 100 and the negative conductive part 2, is less likely to have undervoltage problems, is safer to use, and is also easy to assemble.

[0155] In more detail, the second contact structure 4 can be an arc-shaped contact spring, and a plurality of first hollow openings are evenly formed on the inner end of the negative conductive member 2, and the contact spring is correspondingly formed in each first hollow opening. By adopting the above structure, elastic contact with the negative pole of the battery is achieved, the contact is more stable and sufficient, the power supply connection of the battery is more stable and reliable, and the structure is simple.

[0156] In this embodiment, a pressing member 5 is further inserted into the battery box, and the lower end of the pressing member 5 is a plug-in end 6 bent downward, more specifically, the plug-in end 6 is L-shaped, and a support plate and a mounting block are provided at the corresponding position in the battery box, the support plate and the mounting block are distributed in a T shape, and a slot is formed at the front side of the support plate and the mounting block, and the shape of the slot also corresponds to the shape of the plug-in end 6. The vertical end of the plug-in end 6 is fitted into the slot to fix the pressing member 5 to the battery box, and the upper end of the pressing member 5 is a pressing end 7 bent upward and inward, and the pressing end 7 is located on the downward pressure path of the inner end of the negative conductive member 2. More specifically, the pressing end 7 makes the negative The inner end of the positive conductive member 2 is in close contact with the negative pole of the battery. By arranging a pressing member 5 that matches the inner end of the negative conductive member 2 in the battery box, when the negative pole of the battery acts on the negative conductive member 2, the pressing end 7 of the pressing member 5 provides support force for the negative conductive member, thereby ensuring that the battery is not prone to vibration, so that the first contact structure 3 and the second contact structure 4 are in stable contact with the positive and negative poles of the battery, and the pressing member 5 adopts a structure of a plug-in end 6 and a pressing end 7. Compared with the method of using a support spring, the pressing member 5 can be assembled in the battery box through automation, which makes the assembly efficiency higher, facilitates assembly production, and has a reasonable overall structural design.

[0157] In this embodiment, the pressing end 7 is provided with a first horizontal section 8, and the first horizontal section 8 makes the second contact structure 4 press against the negative pole of the battery. The end of the first horizontal section 8 is bent downward to form an inward limiting section 9, and the head end of the first horizontal section 8 is bent downward to form an elastic section 10. The end of the elastic section 10 is bent horizontally inward to form a second horizontal section 11. The plug-in end 6 is bent and connected to the front side of the second horizontal section 11. By setting the first horizontal section 8 to make the second contact structure 4 press against the negative pole of the battery, compared with the inclined manner, the pressing end 7 will not hinder the downward pressure of the inner end of the negative conductive member 2, and the limiting Due to the setting of segment 9, when the battery is fully inserted, the limiting segment 9 forms a support with the support plate of the battery box, so that the pressing member 5 has a better supporting effect. Through the setting of the elastic segment 10, the pressing end 7 has better elasticity. By setting the second horizontal segment 11 and the plug-in end 6 being bent and connected to the front side of the second horizontal segment 11, the second horizontal segment 11 of the pressing member 5 after being inserted into place will form a contact limit with the support plate. Therefore, the pressing member 5 can form a limiting fit with the support plate and the slot of the battery box, thereby realizing the position limitation of the pressing member 5, ensuring the stable use of the pressing member 5, and the overall structure is reasonable and simple.

[0158] In this embodiment, the head end of the first horizontal section 8 is bent downward to continuously form a first bending portion 12 and a second bending portion 13 that are obliquely inclined and inward. The first bending portion 12 and the second bending portion 13 constitute an elastic section 10. The angle A between the first bending portion 12 and the first horizontal section 8 is less than 30°. The elastic section 10 is composed of the first bending portion 12 and the second bending portion 13, and the angle A between the first bending portion 12 and the first horizontal section 8 is less than 30°. Without taking up too much space, the elastic section 10 has stronger elasticity and the structural design of the pressure member 5 is more reasonable.

[0159] In this embodiment, an elastic notch 14 and a bending notch 15 are further provided on the pressing member 5. The elastic notch 14 is used to divide the limiting section 9. The elastic notch 14 extends to the root along the bending direction of the limiting section 9. The bending notch 15 is used to bend the plug-in end 6. The bending notch 15 extends backward from the front end surface of the second horizontal section 11 to the middle. The setting of the elastic notch 14 divides the limiting section 9 into multiple parts, so that the limiting section 9 can have better elasticity, and the pressure on the pressing member 5 is more reasonable. The formation of the bending notch 15 makes the position of the plug-in end 5 after bending close to the center line of the pressing member 5, so that the distance between the outer end of the adapter 100 and the outer end of the negative conductor 2 is appropriate, and it is safer to use.

[0160] In this embodiment, an elastic contact piece 16 is further provided on the inner end of the adapter sheet 100, which protrudes downward and cooperates with the positive pole of the battery. The suspended end of the elastic contact piece 16 extends backward. By providing the elastic contact piece 16, the elastic contact piece 16 forms a tight contact with the upper end of the positive pole of the battery as the positive pole of the battery gradually snaps into the first contact structure 3, thereby making the contact between the positive pole of the battery and the inner end of the adapter sheet 100 more stable and sufficient, and the power supply connection of the battery more stable and reliable.

[0161] In this embodiment, the battery box also includes a mounting shell 17 and a main cover shell 18 that are interlocked. A battery compartment for mounting the battery is provided in the mounting shell 17. The mounting shell 17 is located on the left and right sides of the battery compartment and is respectively formed with at least one first card slot 19 and at least one second card slot 20. The main cover shell 18 is provided with a first hook plate 21 and a second hook plate 22 at corresponding positions. The first card slot 19 is engaged with the first hook plate 21, and the second card slot 20 is engaged with the second hook plate 22. The mounting shell 17 and the main cover shell 18 are internally buckled and fixed through the cooperation of the first hook plate 21 and the first card slot 19, and the cooperation of the second hook plate 22 and the second card slot 20. The installation is convenient, and there is no obvious connection structure on the outside of the battery box, and the product is more beautiful.

[0162] In this embodiment, the first hook plate 21 and the first slot 19 are centrally formed on the main cover shell 17 and the mounting shell 18, and the first slot 19 is arranged through. An elastic pressing member is also slidably connected inside the first slot 19, and a pressing block 23 is connected on the surface of the elastic pressing member opposite to the first hook plate 21. The pressing block 23 corresponds to the hook setting of the first hook plate 21. Under the action of the elastic pressing member, the pressing block 23 releases the hook on the first hook plate 21 from the engagement with the first slot 19. By pressing the elastic pressing member, the pressing block 23 on its inner side interacts with the hook on the first hook plate 21, causing the first hook plate 21 to deform until the hook moves out of the first slot 19. The engagement between the hook on the first hook plate 21 and the first slot 19 can be released, and the main cover shell 18 can be removed from the mounting shell 17, thereby realizing battery replacement.

[0163] In this embodiment, the elastic pressing member includes a pressing plate 24 and a spring 25. One end of the spring 25 is connected to the inner side surface of the pressing plate 24, and the other end is connected to the inner wall surface of the mounting shell 17. The elastic pressing member is composed of the pressing plate 24 and the spring 25, and has a simple structure. The pressing block 23 is formed on the inner side surface of the pressing plate 24, and a slide groove 26 is formed on the left and right sides of the pressing plate 24. Slide blocks 27 are correspondingly provided on the inner wall surfaces of the left and right sides of the first slot 19. The slide blocks 27 correspond to the slide grooves 26, so that the pressing action of the elastic pressing member is more stable. Anti-slip blocks 28 are also formed at the edges of both sides of the inner wall surface of the pressing plate 24. The setting of the anti-slip blocks 28 avoids the phenomenon of the elastic pressing member falling out, and the overall structure is reasonable.

[0164] In this embodiment, the mounting shell 17 is further provided with weak hook plates 29 on both sides of the first card slot 19, and the main cover shell 18 is correspondingly provided with an auxiliary card slot 30, and a weak card hook plate 29 and the auxiliary card slot 30 form a weak card engagement. By setting a weak card hook plate 29 and an auxiliary card slot 30 weak card engagement structure, and the weak card hook plate 29 and the first card hook plate 21 and the second card hook plate 22 are distributed up and down, more specifically, the elasticity of the weak card hook plate 29 is greater than that of the first card hook plate 21 and the second card hook plate 22. Elasticity, and the hook on the weak hook plate 29 only has the function of auxiliary buckling, that is, when the hook on the first hook plate 21 is released from the first slot 19, the operator only needs to gently act on the mounting shell 18 or the main cover shell 17, and the buckling of the hook of the weak hook plate 29 and the auxiliary slot 30 will be immediately released. Therefore, the setting of this structure can assist the buckling connection between the main cover shell 18 and the mounting shell 17, and will not affect the convenient disassembly of the main cover shell 18 and the mounting shell 17, and the structure is more reasonable.

By providing a pin cavity with a sub-cover shell 33 at the lower end of the mounting shell 17, the outer ends of the adapter 100 and the negative conductive member 2 will cooperate with the socket in the pin cavity, and the power-on position will not be exposed to the outside world, which is safer to use. In addition, the pin groove 32 is provided on the mounting seat 31 in the pin cavity and the corresponding fixing protrusion 34 is provided on the sub-cover shell 33, which realizes the limitation of the outer end position of the adapter 100 and the negative conductive member 2, and is simpler to install than the method of providing an additional mounting plate.
