DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0025] The present utility model embodiment provides a battery housing assembly 1000, such as Figure 1-3 As shown, the battery accommodation assembly 1000 includes: a housing 100, a PCB board 300 and a connecting piece 400, the housing 100 includes an upper housing 101 and a lower housing 102 connected to each other, an accommodation space 103 is formed between the upper housing 101 and the lower housing 102, a plurality of first through holes 1011 are provided on the upper housing 101, and a plurality of second through holes 1021 corresponding to the first through holes 1011 are provided on the lower housing 102, and the first through holes 1011 and the second through holes 1021 are respectively used for At both ends of the exposed battery 200; the PCB board 300 is respectively arranged on a side of the upper shell 101 away from the lower shell 102, and a side of the lower shell 102 away from the upper shell 101, the PCB board 300 is provided with a third through hole 301, and the third through hole 301 is respectively arranged corresponding to the first through hole 1011 and the second through hole 1021, the connecting piece 400 is connected to the PCB board 300 and is located at the third through hole 301, and the connecting piece 400 is used to abut against both ends of the battery 200.

[0026] The housing 100 includes an upper housing 101 and a lower housing 102. The connection between the upper housing 101 and the lower housing 102 can ensure that the internal accommodation space 103 can accommodate the battery 200, while also ensuring the overall structural strength of the housing 100. An accommodation space 103 is provided between the upper housing 101 and the lower housing 102 for storing the battery 200. The two ends of the battery 200 correspond to the first through hole 1011 on the upper housing 101 and the second through hole 1021 on the lower housing 102. PCB boards 300 are provided on the upper housing 101 and the lower housing 102, respectively. The two ends of the battery 200 are exposed through the third through hole 301 provided on the PCB board 300, and are connected to the connecting piece 400 provided on the PCB board 300 to achieve series-parallel connection between the batteries 200. At the same time, through the connecting piece 400, the independent batteries 200 can be combined into a battery 200 module in the battery accommodation assembly 1000 to achieve current transmission of the battery 200 module. Because the connecting piece 400 is arranged at the third through hole 301, it can be connected to both ends of the battery 200, that is, the connecting piece 400 can be connected to the positive electrode of the battery 200, and can also be connected to the negative electrode of the battery 200, so in the production design process of the battery accommodation component, only one type of connecting piece 400 needs to be designed, and there is no need to design and produce different types of connecting pieces 400 for the positive and negative electrodes of the battery 200, thereby improving the reuse rate of the connecting piece 400. Therefore, the design and production cost of the battery accommodation component 1000 can be reduced to a certain extent, and the number of mold openings for stamping the connecting piece 400 can be reduced.

[0027] Specifically, the housing 100 is formed by connecting an upper housing 101 and a lower housing 102 to form a housing space 103. While ensuring that the housing 100 protects the battery 200 assembly, the upper housing 101 and the lower housing 102 are detachable, which facilitates the installation and removal of the battery 200 in the housing space 103 of the battery housing assembly 1000, and facilitates the operation and maintenance of the battery housing assembly 1000 and the battery 200 by users.

[0028] Specifically, the third through hole 301 on the PCB board 300 corresponds to the first through hole 1011 on the upper shell 101 and the second through hole 1021 on the lower shell 102, respectively, and is used to expose the two ends of the battery 200 and connect them to the connecting piece 400 set on the PCB board 300, thereby reducing the possibility of the outer shell 100 and the PCB board 300 affecting the connection between the battery 200 and the connecting piece 400.

[0029] Specifically, the PCB board 300 is connected to the battery 200 through the connecting piece 400 to realize the series and parallel connection of the battery 200, ensuring the normal operation of the current transmission in the circuit. At the same time, the PCB board 300 is respectively arranged at the position of the upper shell 101 and the lower shell 102, which can effectively isolate the battery 200 and other electronic components, protect the normal operation of the circuit, and improve the safety and stability of the battery accommodating assembly 1000.

[0030] refer to Figures 1 to 3 A plurality of first limiting sleeves 1012 are provided on the upper shell 101, a plurality of second limiting sleeves 1022 are provided on the lower shell 102 opposite to the first limiting sleeves 1012, the first through hole 1011 is connected to the first limiting sleeves 1012, and the second through hole 1021 is connected to the second limiting sleeves 1022.

[0031] The first limiting sleeve 1012 and the second limiting sleeve 1022 are used to limit and protect the battery 200, so as to prevent the battery 200 from shaking and shifting between the upper shell 101 and the lower shell 102, and effectively improve the stability of the battery 200 in the battery housing assembly 1000. At the same time, the first limiting sleeve 1012 and the second limiting sleeve 1022 can also cover the two side ends of the battery 200, which can provide a certain protection effect on the battery 200, improve the protection of the battery housing assembly 1000 on the battery 200, reduce the risk of the battery 200 being affected by the external environment, and improve the safety of the battery 200 in the battery housing assembly 1000.

[0032] Specifically, the first limiting sleeve 1012 and the second limiting sleeve 1022 can realize accurate positioning of the battery 200, which helps the battery 200 to be placed in the correct position conveniently and quickly during the installation process. This facilitates the installation of the battery 200 in the battery receiving assembly 1000, which can help speed up the installation process, reduce assembly time, and improve production efficiency.

[0033] refer to Figure 4 and Figure 5 The PCB board 300 is provided with a limiting groove 302 , and the limiting groove 302 is arranged on two opposite sides of the diameter of the third through hole 301 , and the connecting piece 400 is arranged on the PCB board 300 through the limiting groove 302 .

[0034] The connecting piece 400 is installed on the PCB board 300 through the limiting groove 302, which can ensure that the connecting piece 400 can be quickly and accurately positioned and installed on the PCB board 300 through the limiting groove 302. The limiting groove 302 helps to ensure the correct corresponding installation between the connecting piece 400 and the PCB board 300, and improves the accuracy and reliability of the assembly of the two. On the other hand, installing the connecting piece 400 on the limiting groove 302 of the PCB board 300 can fix the connecting piece 400 on the PCB board 300, avoid the problem of looseness or displacement during use, and improve the stability and reliability of the battery accommodating assembly 1000.

[0035] Specifically, the connection piece 400 is installed corresponding to the limiting groove 302, so that the connection piece 400 is easier to install and remove, which is beneficial to the maintenance and replacement of the connection piece 400 and the PCB board 300, and reduces the time and cost of maintenance.

[0036] refer to Figure 6 The connecting piece 400 includes two connecting parts 401 and an abutting part 402 arranged between the two connecting parts 401. The connecting part 401 includes a bending section 4011 arranged at one end of the connecting part 401 away from the abutting part 402; the bending section 4011 is bent toward the side away from the shell 100, the bending section 4011 is connected to the limiting groove 302, and the abutting part 402 is located in the third through hole 301.

[0037] The two connecting parts 401 of the connecting piece 400 are respectively provided with bending sections 4011, and the bending sections 4011 are used to connect with the limiting grooves 302 on the opposite sides of the third through hole 301. The abutting part 402 provided between the two bending sections 4011 is used to abut against the battery 200 to realize the current transportation of the battery 200. The bending section 4011 is bent toward the side away from the housing 100, which can increase the connection stability between the connecting piece 400 and the limiting groove 302, prevent the risk of the connecting piece 400 falling off from the PCB board 300 due to external force during use, and avoid the connection between the connecting piece 400 and the PCB board 300 from failing or being damaged.

[0038] Specifically, the contact portion 402 is located in the third through hole 301, so that the connecting piece 400 has a larger contact area when contacting the battery 200, ensuring a stable and reliable connection between the contact portion 402 and the battery 200. At the same time, the connecting piece 400 can be subjected to a more uniform force distribution during assembly, avoiding poor connection or damage to the connecting piece 400 due to excessive or uneven force during the contact between the connecting piece 400 and the battery 200.

[0039] In an optional embodiment of the present invention, the abutting portion 402 is connected to the battery 200 by welding, and the bending section 4011 is connected to the limiting groove 302 by welding.

[0040] The abutment portion 402 is welded to the battery 200, and the welding connection between the bending section 4011 and the limiting groove 302 can stably and firmly connect the connecting piece 400 to the battery 200 and the PCB board 300, thereby ensuring the stability and reliability of the connection between the connecting piece 400 and the battery 200, and between the connecting piece 400 and the PCB board 300, avoiding disconnection or looseness during use, and improving the performance and reliability of the battery accommodating assembly 1000.

[0041] Specifically, the abutment portion 402 is welded to the battery 200, and the bending section 4011 is welded to the limiting groove 302 to ensure good circuit connection quality between the connecting piece 400 and the battery 200 and the PCB board 300, thereby avoiding circuit failure or performance degradation caused by poor connection.

[0042] Specifically, the welding connection is usually stronger and more stable than other connection methods, which can ensure that the connector 500 will not loosen or detach from the battery 200 or the PCB board 300 during use, thereby improving the reliability of the battery accommodating assembly 1000. The welding connection can also provide good electrical conductivity to ensure that the circuit connection quality of the battery accommodating assembly 1000 is good. The welding connection is usually more compact than the traditional bolt, nut or threaded connection, which can save space and reduce the occupied space of the battery accommodating assembly 1000. In addition, the welding connection can provide better corrosion resistance, which can keep the battery accommodating assembly 1000 stable for a long time.

[0043] refer to Figure 6 The connecting portion 401 further includes an elastic section 4012 , which is disposed between the bending section 4011 and the abutting portion 402 , and a bending direction of the elastic section 4012 is the same as a bending direction of the bending section 4011 .

[0044] The elastic section 4012 on the connecting portion 401 can provide a certain shock absorption and buffering effect for the connecting piece 400, and can absorb the vibration or shaking generated during transportation and use. When the connecting piece 400 is subjected to external impact or vibration, the elastic section 4012 can absorb part of the impact force, protect the connecting piece 400 and the PCB board 300 and the battery 200 connected to the connecting piece 400, ensure the stability and reliability of the connecting piece 400, and extend the service life of the battery accommodating assembly 1000.

[0045] On the other hand, the elastic section 4012 can effectively absorb the height process difference caused by welding and assembly process, ensure that the connecting piece 400 fits both ends of the battery 200, and avoid the generation of cold solder joints between the connecting piece 400 and the battery 200 and the PCB board 300.

[0046] Specifically, the presence of the elastic section 4012 can ensure that the connector 500 has a certain margin to a certain extent, thereby preventing the connector 500 from becoming loose or disconnected due to changes in its own structure caused by external vibration or temperature changes.

[0047] refer to Figure 4 and 5 The upper shell 101 and the lower shell 102 are respectively provided with limiting columns 1013, and the PCB board 300 is provided with limiting holes 303, and the limiting columns 1013 are snap-fitted with the limiting holes 303.

[0048] The clamping connection between the limiting column 1013 and the limiting hole 303 can ensure that the connection between the PCB board 300 and the upper shell 101 and the lower shell 102 is stable and firm, thereby improving the reliability and performance stability of the battery accommodating assembly 1000. On the other hand, it can also enable the PCB board 300 to be accurately connected and positioned with the upper shell 101 and the lower shell 102, respectively, improve the assembly accuracy and stability of the battery accommodating assembly 1000, avoid deviation or misalignment during the assembly process, and reduce assembly time and cost.

[0049] Specifically, the clamping connection between the limit post 1013 and the limit hole 303 can simplify the assembly process, reduce the time and labor cost required for assembly, improve the efficiency and speed of assembly, and thus improve production efficiency. The connection between the PCB board 300 and the limit post 1013 through the limit hole 303 can make the battery accommodating assembly 1000 easier to disassemble and maintain, thereby improving the efficiency of inspection and maintenance.

[0050] In an optional embodiment of the present invention, the PCB board 300 is connected to the upper housing 101 and / or the lower housing 102 respectively by screws.

[0051] Using screws to connect the PCB board 300 to the upper shell 101 and / or the lower shell 102 can ensure that the connection between the PCB board 300 and the upper shell 101 and / or the lower shell 102 is firm and reliable, avoid loosening or displacement of the PCB board 300 during use, and improve the overall stability of the battery housing assembly 1000.

[0052] It should be noted that the PCB board 300 can be connected to the upper shell 101 and the lower shell 102 at the same time by screws, or it can be connected to only one of the upper shell 101 and the lower shell 102 by screws, and the other one can be connected to the PCB board 300 by other means such as: snap connection, adhesive connection or welding connection.

[0053] Specifically, the screw connection design makes the PCB board 300 easier to disassemble and replace, simplifies the maintenance and repair process, helps to perform maintenance operations faster, and reduces the maintenance time and cost of the battery housing assembly 1000.

[0054] Specifically, the screw connection is relatively simple and easy to operate, which is beneficial to the assembly process of the battery accommodating assembly 1000, reduces assembly time, and improves production efficiency.

[0055] refer to Figure 2 A connecting column 1023 is provided on the upper shell 101 and / or the lower shell 102 , and the two connecting columns 1023 , or the connecting column 1023 and the upper shell 101 and / or the lower shell 102 are connected via a connecting piece 500 .

[0056] The two connection posts 1023, or the upper shell 101 and the connection post 1023, or the lower shell 102 and the connection post 1023 are connected via the connection piece 500. The connection between the connection piece 500 and the connection post 1023 makes the connection between the upper shell 101 and the lower shell 102 more secure, which can enhance the overall structural stability of the battery housing assembly 1000, reduce the possibility of looseness and vibration between the upper shell 101 and the lower shell 102, and improve the use stability of the battery housing assembly 1000.

[0057] Specifically, by providing the connection column 1023 on the upper shell 101 and / or the lower shell 102 for connection and installation, accurate positioning between the upper shell 101 and the lower shell 102 can be achieved, ensuring that the upper shell 101 and the lower shell 102 are correctly aligned during the assembly process, avoiding assembly deviation, and improving the assembly accuracy of the battery accommodating assembly 1000. The connection between the connection column 1023 and the connector 500 can also simplify the assembly process of the battery accommodating assembly 1000, reduce assembly time and labor costs, and improve production efficiency.

[0058] Specifically, the connection method between the connecting column 1023 and the connecting member 500 can make the disassembly and maintenance of the battery accommodating assembly 1000 easier, reducing the damage or errors that may occur during the disassembly and maintenance process.

[0059] It should be noted that the connecting posts 1023 may be provided on both the upper shell 101 and the lower shell 102, and the connecting posts 1023 on both sides are provided correspondingly, so in the actual installation process, the connecting posts 1023 on the upper shell 101 are connected correspondingly to the connecting posts 1023 on the lower shell 102. Alternatively, the connecting posts 1023 may be provided on both the upper shell 101 and the lower shell 102, and the connecting posts 1023 may be staggered, so in the actual installation process, the connecting posts 1023 on the upper shell 101 are directly connected to the lower shell 102, and the connecting posts 1023 on the lower shell 102 are directly connected to the upper shell 101.

[0060] A connecting column 1023 may also be provided on one of the upper shell 101 and the lower shell 102 to connect with the other one.
