Description

Technical Field

[0001] The utility model relates to the field of battery boxes, in particular to an improved battery box for placing a battery module. Background Art

[0002] As an electrical connection component between a power source and an electrical appliance, a dual-battery battery box has been widely used in meters, smart devices, small appliances and other equipment that require electrical and signal connections. However, there are major problems in the existing dual-battery battery boxes. The current dual-battery box shell is assembled from a front half shell and a rear half shell, so there will be an installation gap after installation. In addition, during the testing process, it was found that the internal batteries of the battery box with this structure would be oxidized, causing the spring fragments to contact the oxidized position and cause poor contact. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned prior art, the purpose of the utility model is to provide an improved battery box for placing battery modules, which has a reasonable design, good use effect and long service life.

[0004] The utility model adopts a technical solution to solve its technical problems. It is an improved battery box for placing a battery module, comprising a battery box shell, at least one elastic member, and two conductive members. A accommodating cavity is provided in the battery box shell, and a battery module is placed in the accommodating cavity. The elastic member is provided at one end of the accommodating cavity and abuts against the battery module. The conductive members are provided at the other end of the accommodating cavity. The conductive members are electrically connected to the battery module so that the battery module outputs current. The battery box shell is composed of a shell seat and a mounting seat. The accommodating cavity is formed on the shell seat, and at least one side of the vertical end of the accommodating cavity is set as an opening. The mounting seat is set corresponding to the opening, and the mounting seat is tightly connected and matched with the opening.

[0005] The advantages of adopting the above technical solution are as follows: after the battery module is installed, the two conductive parts arranged on the same side can enable the battery module to output current, thereby realizing the power supply operation for the components on the circuit board, and by arranging the elastic part, the battery module has a better shockproof effect, thereby ensuring the stability of the contact, by forming the accommodating cavity on the shell seat, and setting the vertical end of the accommodating cavity as an open structure and arranging the conductive parts on the same side, compared with the prior art, the battery box shell is composed of a front half shell and a rear half shell, and the installation direction of the battery module is from front to back. The arrangement of the above structure makes the installation direction of the battery module vertical, and the assembly of the battery module is more convenient. At the same time, the opening of the accommodating cavity is effectively sealed through the corresponding mounting seat, so that no installation gap is generated on the battery box shell, so that the battery module installed in the accommodating cavity is effectively isolated from the outside during use, so the battery module will not be oxidized, and good contact between the conductive part and the battery module is guaranteed. Therefore, the battery box with dual batteries of this structure has reasonable design, good use effect and long service life.

[0006] Furthermore, a surrounding flange is provided on the inner wall surface of the mounting seat, and the outer peripheral wall surface of the flange is tightly fitted with the inner peripheral wall surface of the opening.

[0007] The advantages of adopting the above technical solution are as follows: by setting a flange that fits tightly with the inner wall of the opening, effective protection of the contact position between the conductive part and the battery is achieved, and there is no obvious connection feature on the outside of the battery box shell after assembly, and the shape is also beautiful. In addition, the setting of the flange can also use the high-frequency vibration wave generated by ultrasonic welding technology to fuse the molecular layers of the contact surface of the flange and the opening into one, so that the mounting seat and the shell seat are better sealed, thereby ensuring the normal operation of the battery box and the structural design is more reasonable.

[0008] Furthermore, a buckle is provided on the outer peripheral wall surface of the flange, and a slot is provided on the inner peripheral wall surface of the opening, and the buckle is matched with the slot.

[0009] The advantages of adopting the above technical solution are as follows: through the arrangement of the buckle and the slot, the fixing effect of the mounting seat and the shell seat is better, the occurrence of separation is effectively prevented, and the structural design is simple and reasonable.

[0010] Furthermore, a first contact piece is provided on the inner end of each of the conductive pieces. Each of the first contact pieces is configured as a contact ring, and the top of each of the contact rings is curved outward and downward to form an elastic contact with the other end of the battery module.

[0011] The advantages of adopting the above technical solution are: on the one hand, the first contact piece can be used as an electrical connector to realize the conductive function; on the other hand, the top end of the first contact piece is bent outward and downward in an arc shape. In this way, during the extrusion of the battery module toward the conductive piece, the upper end of the first contact piece maintains stable contact with the other end of the battery module while also undergoing a certain degree of radial deformation. Therefore, the first contact piece can also be used as an elastic pressure piece of the battery module, so that the battery can be more reliably installed in the accommodating cavity, and the structural setting is reasonable.

[0012] Furthermore, a second contact piece is provided on the inner end of each conductive piece. The second contact piece is configured as a contact sheet, and the top of the contact sheet is curved inwardly of the first contact piece to form an elastic contact with the other end of the battery module.

[0013] Advantages of the above technical solution: by arranging a second contact piece on the inner end of the conductive piece, and the second contact piece is a contact sheet, the top of which is bent in an arc shape toward the inside of the first contact piece. This design enables a double and all-round contact connection with the other end of the battery module to be achieved with the first contact piece, and the power supply connection of the battery module is more stable and reliable.

[0014] Furthermore, an upper portion of the first contact piece is provided with an evenly divided first notch, and an upper portion of the second contact piece is provided with an evenly divided second notch.

[0015] Advantages of adopting the above technical solution: the formation of the first notch divides the upper part of the first contact piece into multiple elastic parts, the first contact piece has better elasticity, ensuring that the first contact piece is in stable contact with the other end of the battery, and can also be reasonably stretched and deformed. The setting of the second notch divides the upper part of the second contact piece into multiple elastic parts, the second contact piece has better elasticity. The setting of the above structure makes the power supply connection between the conductive member and the battery module more stable and reliable.

[0016] Furthermore, a first mounting structure that cooperates with the first contact piece and the second contact piece is also provided on the inner wall surface of the battery box shell.

[0017] The advantages of adopting the above technical solution are as follows: by setting the corresponding first mounting structure, the conductive member can be stably installed in the battery box housing, and the cooperation between the first contact member and the second contact member and the battery module is more stable, and the structural design is reasonable.

[0018] Furthermore, the first contact members on the inner ends of the conductive members are all configured as springs.

[0019] Advantages of adopting the above technical solution: Therefore, the first contact piece on the conductive piece can also adopt a spring structure, which can greatly improve the shockproof performance, and not only has a simple structure, but also reduces the difficulty of assembly and processing complexity, and the cost of use will also be lower.

[0020] Furthermore, a second mounting structure cooperating with the elastic member is also provided on the inner wall surface of the battery box shell.

[0021] The advantages of adopting the above technical solution are as follows: by providing a corresponding second mounting structure, the elastic member can be stably mounted in the battery box housing, thereby making the cooperation with the battery module more stable and the structural design reasonable.

DETAILED DESCRIPTION

[0031] In order to more clearly illustrate the embodiments of the utility model and / or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work. In addition, the orientation only represents the relative position relationship between the components, not the absolute position relationship.

[0032] See also Figures 1 to 8 As shown, an improved battery box for placing a battery module includes a battery box shell 1, at least one elastic member 2, and two conductive members 3. A accommodating cavity 4 is provided in the battery box shell 1, and a battery module 5 is placed in the accommodating cavity 4. More specifically, the battery module 5 can be a battery or a battery block arranged side by side, and the corresponding elastic member 2 can be connected or separate, and can also be a conductor or not. Its main function is elastic resistance.

[0033] In this embodiment, the elastic member 2 is arranged at one end of the accommodating cavity 4 and abuts against the battery module 5, and the conductive member 3 is arranged at the other end of the accommodating cavity 4. The conductive member 3 is electrically connected to the battery module 5 so that the battery module 5 outputs current. The battery box shell 1 is composed of a shell seat 6 and a mounting seat 7. The accommodating cavity 4 is formed on the shell seat 6, and at least one side of the vertical end of the accommodating cavity 4 is set as an opening, and the mounting seat 7 is set corresponding to the opening. More specifically, in order to ensure the stability of each component, the number of openings of the accommodating cavity 4 is specifically one, that is, the opening is formed at the upper end or the lower end of the accommodating cavity 4, and there is only one corresponding mounting seat 7, and the mounting seat 7 is tightly connected and matched with the opening.

[0034] In the above structure, after the battery module 5 is loaded, the two conductive members 3 arranged on the same side can enable the battery module 5 to output current, thereby realizing the power supply operation for the components on the circuit board, and the battery module 5 has a better shockproof effect by arranging the elastic member 2, thereby ensuring the stability of the contact, and by forming the accommodating cavity 4 on the shell seat 6, and setting one side end of the accommodating cavity 4 in the vertical direction as an open structure and arranging the conductive member 3 on the same side, compared with the prior art, the battery box shell is composed of the front half shell and the rear half shell, and the installation direction of the battery module 5 is In a forward-to-backward manner, the arrangement of the above structure makes the installation direction of the battery module 5 vertical, and the assembly of the battery module 5 is relatively convenient. At the same time, the corresponding mounting seat 6 is used to effectively seal the opening of the accommodating cavity 7, so that no installation gap is generated on the battery box shell 1, so that the battery module 5 installed in the accommodating cavity 4 is effectively isolated from the outside during use, so that the battery module 5 will not be oxidized, ensuring good contact between the conductive part 3 and the battery module 5. Therefore, the improved battery box of this structure is reasonably designed, has a good use effect, and a long service life.

[0035] In the above embodiment, a surrounding flange 8 is provided on the inner wall surface of the mounting seat 7, and the outer peripheral wall surface of the flange 8 is tightly fitted with the inner peripheral wall surface of the opening. By setting the flange 8 that is tightly fitted with the inner peripheral wall surface of the opening, effective protection of the contact position between the conductive part and the battery module 5 is achieved, and there is no obvious connection feature on the outside of the battery box shell 1 after assembly, and the shape is also beautiful. In addition, the setting of the flange 8 can also use the high-frequency vibration wave generated by ultrasonic welding technology to fuse the contact surface molecular layers of the flange 8 and the opening into one, so that the mounting seat 7 and the shell seat 6 are better sealed, thereby ensuring the normal operation of the battery box and the more reasonable structural design.

[0036] In the above embodiment, a buckle 9 is further provided on the outer wall surface of the flange 8, and a slot 10 is further provided on the inner wall surface of the opening. The buckle 9 corresponds to the slot 10. Through the arrangement of the buckle 9 and the slot 10, the fixing effect of the mounting seat 7 and the shell seat 6 is better, and the occurrence of detachment is effectively prevented. The structural design is simple and reasonable.

[0037] In the above embodiment, in order to facilitate quick fit between the buckle 9 and the slot 10, the lower end surface of the buckle 9 can be set as a first bevel surface, and the wall surface at the opening directly above the slot 10 can be set as a second bevel surface that matches the first bevel surface.

[0038] In the above embodiment, a first contact piece 11 is provided on the inner end of the conductive member 3, and the first contact piece 11 is configured as a contact ring, and the top end of the contact ring is bent outward and downward in an arc shape to form an elastic resistance with the other end of the battery module 5. On the one hand, the first contact piece 11 can be used as an electrical connector to realize the conductive function, and on the other hand, the top end of the first contact piece 11 is bent outward and downward in an arc shape. With this configuration, during the extrusion of the battery module 5 toward the conductive member 3, the upper end of the first contact piece 11 maintains stable contact with the other end of the battery module 5 while also undergoing a certain degree of radial deformation. Therefore, the first contact piece 11 can also serve as an elastic pressure piece of the battery module 5, so that the battery module 5 can be more reliably installed in the accommodating cavity 4, and the structural setting is reasonable.

[0039] In the above embodiment, the first contact member 11 is integrally formed on the conductive member 3 by a metal sheet through a bending process. The first contact member 11 is reasonably formed, and the conductive member 3 has a higher strength in use. The battery box with this structure can be used in special occasions requiring high stability.

[0040] In the above embodiment, a second contact member 12 is further provided on the inner end of the conductive member 3, and the second contact member 12 is configured as a contact sheet, and the top of the contact sheet is curved and bent toward the inside of the first contact member 11 to form an elastic resistance with the other end of the battery module 5. By arranging the second contact member 12 on the inner end of the conductive member 3, and the second contact member 12 is a contact sheet, and the top of the contact sheet is curved and bent toward the inside of the first contact member, this design enables a double and all-round contact connection with the other end of the battery module 5 to be achieved with the first contact member 11, and the power supply connection of the battery module 5 is more stable and reliable. At the same time, the second contact member 12 can be integrally formed on the conductive member 3 through a bending process. The conductive member 3 is reasonably formed, which also ensures that the conductive member 3 has a high strength of use.

[0041] In the above embodiment, the upper part of the first contact member 11 is provided with an evenly divided first notch 13, and the upper part of the second contact member 12 is provided with an evenly divided second notch 14. The formation of the first notch 13 divides the upper part of the first contact member 11 into a plurality of elastic parts. The first contact member 11 has better elasticity, ensuring that the first contact member 11 is in stable contact with the other end of the battery module 5, and can also be reasonably stretched and deformed. The setting of the second notch 13 divides the upper part of the second contact member 12 into a plurality of elastic parts. The second contact member 12 has better elasticity. The setting of the above structure makes the power supply connection between the conductive member 3 and the battery module 5 more stable and reliable.

[0042] In the above embodiment, a first mounting structure 15 for matching the first contact 11 and the second contact 12 is also provided on the inner wall surface of the battery box shell 1. More specifically, the first mounting structure 15 includes a boss correspondingly formed on one side of the insertion hole, and a corresponding accommodating cavity and an insert slot are formed on the boss. The accommodating cavity is used to place the first contact 11, so as to prevent the first contact 11 from excessive radial deformation. The insert slot is used to match the connecting section of the conductive member 3. A supporting boss for matching the second contact 12 is also provided at the center of the accommodating cavity. It should be noted that when the accommodating cavity 4 is a structure with an upper end opening, the first mounting structure 15 is formed on the bottom inner wall surface of the shell seat 6. When the accommodating cavity 4 is a structure with a lower end opening, the first mounting structure 15 is formed on the inner wall surface of the mounting seat 7 arranged at the corresponding opening.

[0043] Of course, the first contact piece 11 on the inner end of the conductive piece 3 is set as a spring. At this time, there is no need to set the second contact piece 12 on the inner end of the conductive piece 3. Therefore, the first contact piece 11 on the conductive piece 3 adopts a spring structure. This structure can greatly improve the shockproof performance, and not only has a simple structure, but also reduces the difficulty of assembly and processing complexity, and the cost of use will be lower. At the same time, since the pin portion of the conductive piece 3 extends to the outside of the battery box shell 1 through the socket to connect with the external connecting seat, in order to avoid interference with the first contact piece 11, the conductive piece 3 at this time only needs to achieve the purpose of installation and positioning through the cooperation of the socket and the pin portion. At this time, there is no need to set the first mounting structure 15 in the battery box shell 1.

[0044] In the above embodiment, a second mounting structure 16 for matching with the elastic member 2 is further provided on the inner wall surface of the battery box shell 1. More specifically, the second mounting structure 15 includes a recessed cavity for placing the elastic member 2, and a plug-in column formed in the recessed cavity. The above structure enables stable installation of the elastic member 2, thereby making the cooperation with the battery module 5 more stable and the structural design reasonable.

[0045] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
