Description

Technical Field

[0001] This application relates to the fields of electrochemistry and battery technology, and in particular to a battery box. Background Technology

[0002] A battery box is a structural component or assembly used to fix, house, and connect batteries. It is widely used in consumer electronics, home appliances, industrial equipment, medical instruments, and smart hardware. It not only provides mechanical support and protection but also enables the electrical connection between the battery and external circuitry, making it a key interface component in power systems.

[0003] Existing battery boxes typically use a bridging method to achieve electrical connection between the plug-in and the battery electrodes, that is, to indirectly connect the plug-in and the battery terminals through wires or metal connecting pieces. This structure results in a longer connection path, which not only increases the resistance and loss of current transmission, but also increases material costs. Utility Model Content

[0004] The purpose of this application is to provide a battery box that shortens the connection path, reduces current transmission resistance and loss, and also reduces material costs.

[0005] The embodiments of this application can be implemented as follows:

[0006] In a first aspect, the present invention provides a battery box, including a box body, a conductor, a connector and an elastic kit;

[0007] The housing has a cavity for accommodating the battery and a through hole communicating with the cavity;

[0008] The connecting seat is assembled on the outside of the box body, and the connecting seat is provided with a mounting hole, the mounting hole and the through hole being opposite to each other;

[0009] The elastic component is fixed inside the mounting hole;

[0010] The conductor passes through the perforation and a portion extends into the receiving cavity. The portion of the conductor inside the receiving cavity is used to directly connect with the battery electrode, and the portion of the conductor outside the casing extends into the elastic sleeve.

[0011] The elastic sleeve has a portion recessed toward the conductor to elastically support the conductor.

[0012] Compared with the prior art, the beneficial effects of the embodiments of this application include, for example:

[0013] The housing cavity of the casing can be used to house the battery. The casing has through holes communicating with the housing cavity for conductors to pass through, allowing part of the conductor to be inside the housing cavity and the other part outside the casing. The connector mounted on the outside of the casing has mounting holes for fixing the elastic component. The elastic force provided by the elastic component effectively fixes the conductor radially, ensuring the conductor's fixation effect, improving fixation stability, and guaranteeing a durable connection. Furthermore, the elastic support ensures an effective electrical connection between the elastic component and the conductor at all times, improving electrical contact performance, reducing contact resistance, and increasing current transmission efficiency. External electrical components can be directly connected to the elastic component, reducing the safety hazard of localized overheating and fire caused by poor contact. The portion of the conductor located inside the housing cavity can be directly fixedly connected to the battery electrodes, eliminating the need for an intermediate medium to bridge the connector between the insert conductor and the electrodes as in existing technologies. This shortens the connection path, reduces current transmission resistance and loss, and also lowers material costs. Attached Figure Description

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0046] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0048] refer to Figures 1 to 3 This application discloses a battery box, including a box body 100, a conductor 300 and a connector 400;

[0049] The housing 100 has a receiving cavity 110 for accommodating the battery 600 and a through hole 121 communicating with the receiving cavity 110;

[0050] The connector 400 is assembled on the outside of the housing 100, and the connector 400 is provided with a mounting hole 410, which is opposite to the through hole 121;

[0051] The conductor 300 passes through the through hole 121 and a portion extends into the receiving cavity 110. The portion of the conductor 300 located in the receiving cavity 110 is used to directly connect with the electrode of the battery 600, and the portion of the conductor 300 located outside the housing 100 is fixed in the mounting hole 410.

[0052] In this way, the receiving cavity 110 of the housing 100 can be used to house the battery 600. The housing 100 is provided with a through hole 121 communicating with the receiving cavity 110, which allows the conductor 300 to pass through, so that part of the conductor 300 is located inside the receiving cavity 110 and the other part is located outside the housing 100. The connector 400 mounted on the outside of the housing 100 is provided with a mounting hole 410 to fix the conductor 300, ensuring the fixing effect of the conductor 300. The part of the conductor 300 located inside the receiving cavity 110 can be directly fixedly connected to the electrode of the battery 600, eliminating the need for an intermediate medium to bridge the insert conductor 300 and the electrode as in the prior art. Therefore, the connection path is shortened, the current transmission resistance and loss are reduced, and the material cost is also reduced.

[0053] It is understood that the shape of the housing 100 is adapted to the shape of the battery 600. For example, if the battery 600 is a cylindrical battery 600, then the shape of the housing 100 is approximately a hollow cylinder as shown in the embodiments in the accompanying drawings, and the accommodating cavity 110 is also cylindrical accordingly. Of course, in some embodiments not shown, the housing 100, the accommodating cavity 110, and the battery 600 may also be square.

[0054] refer to Figures 3 to 5 An integral plug-in portion 120 is formed on the side wall of the box body 100 near the opening of the accommodating cavity 110. The plug-in portion 120 mainly provides space for the installation of the conductor 300 and the connector 400. Under the premise of ensuring that the structural strength of the box body 100 and the effective space of the accommodating cavity 110 are not affected, the amount of material used in the box body 100 is reduced, thereby reducing the manufacturing cost.

[0055] Specifically, the plug-in portion 120 is generally rectangular in shape and is located on the outer side of the receiving cavity 110 in the radial direction. The plug-in portion 120 is provided with a slot 122, a through hole 121 and a guide post 130. The slot 122 is located in the radial direction between the through hole 121 and the receiving cavity 110. The slot 122 connects the through hole 121 and the receiving cavity 110. The conductor 300 is inserted into the slot 122.

[0056] The slot 122 is divided into a connected insertion section 1221 and a tapered section 1220 along its depth direction. The bottom wall of the insertion section 1221 serves as the bottom wall of the entire slot 122, while the opening of the tapered section 1220 serves as the slot opening of the entire slot 122. Therefore, the insertion section 1221 is the end opening further away from the receiving cavity 110 than the tapered section 1220. From the bottom of the slot to the opening of the slot 122, the width of the insertion section 1221 remains constant, while the width of the tapered section 1220 gradually increases. Therefore, the tapered section 1220 is flared, which facilitates the direct insertion of the conductor 300 into the slot 122 on the insertion part 120 of the housing 100 by the guide of the tapered section 1220 during installation, thus improving assembly efficiency.

[0057] refer to Figure 5 and Figure 6 The connector 400 is provided with a guide hole 420 for insertion and mating with the guide post 130, thereby realizing the positioning between the connector 400 and the box 100 and facilitating the quick assembly of the box 100 and the connector 400.

[0058] A reinforcing rib 140 is provided between the outer wall of the housing 100 and the guide post 130. The reinforcing rib 140 improves the strength of the guide post 130, making it less prone to breakage under stress, resulting in better product performance. To accommodate the reinforcing rib 140, a relief groove 430 communicating with the guide hole 420 is also provided on the connecting seat 400 to accommodate the reinforcing rib 140.

[0059] Of course, it's understandable that because batteries 600 typically have positive and negative electrodes, there are usually two conductors 300 in a battery case. Figure 7 and Figure 8 One conductor 300 is connected to the positive terminal, and the other conductor 300 is connected to the negative terminal. In other words, the two conductors 300 are respectively connected as the first conductor 340 and the second conductor 350, with the first conductor 340 connected to the positive terminal and the second conductor 350 connected to the negative terminal. Correspondingly, the insertion part 120 of the housing 100 has two through holes 121 and two slots 122, so that the two conductors 300 can be inserted into the slots 122 and pass through the through holes 121 respectively. The guide post 130, the reinforcing rib 140 and the guide hole 420 are located between the two conductors 300.

[0060] The top edges of the first conductor 340 and the second conductor 350 (that is, the side away from the bottom of the accommodating cavity 110) are at the same height.

[0061] Furthermore, the end opening of the accommodating cavity 110 needs to be sealed to ensure that the battery box can protect the battery 600 from all directions. Specifically, refer to... Figure 1 , Figure 2 and Figure 9 The battery box also includes a top cover 200, which is installed at one end of the box body 100 to cover the receiving cavity 110.

[0062] The top cover 200 and the box body 100 can be connected by any method such as welding, screwing, or snap-fitting. The box body 100 has a first hole 123 and a second hole 150 on its end face. The first hole 123 is specifically set on the insertion part 120 of the box body 100 and is located between the two through holes 121. The layout is more reasonable. While ensuring a sufficient safe distance between the two conductors 300, the size of the entire insertion part 120 is reduced, and the compactness of the battery box is improved.

[0063] The upper cover 200 is provided with a first positioning post 210 and a second positioning post 220. The first positioning post 210 cooperates with the first hole 123, and the second positioning post 220 cooperates with the second hole 150. In this way, the upper cover 200 and the cover body can be positioned to prevent the relative position of the box body 100 and the upper cover 200 from shifting, which facilitates the subsequent welding process, thereby improving assembly efficiency. It can also increase the contact area between the upper cover 200 and the box body 100 and improve the connection reliability.

[0064] refer to Figure 3 , Figure 4 and Figure 10 The conductor 300 includes a contact piece 310, an adapter piece 320, and an extension 330 connected at an angle in sequence; the contact piece 310 is used to fix the connection with the electrode of the battery 600; the adapter piece 320 is embedded in the slot 122; the extension 330 passes through the through hole 121 and is fixed in the mounting hole 410.

[0065] By dividing the conductor 300 into a multi-segment design consisting of a contact piece 310, an adapter piece 320, and an extension section 330, the contact piece 310 is fixedly connected to the electrode of the battery 600 to ensure a firm starting point for current conduction. The adapter piece 320 is embedded in the slot 122 to provide reliable positioning and support. The extension section 330 is fixed to the connector 400 to ensure that the entire conductor 300 is reliably fixed. This improves the mechanical stability of the connection between the conductor 300 and the housing 100, as well as the long-term reliability of the electrical connection between the conductor 300 and the battery 600.

[0066] Of course, it is understandable that, since the positive and negative electrodes of the cylindrical battery 600 are located at opposite ends, the contact pieces 310 in the two conductors 300 corresponding to the positive and negative electrodes, respectively, have different structures. (Refer to...) Figure 7 and Figure 8 For example, the contact piece 310 in the first conductor 340 is further away from the bottom of the receiving cavity 110 than the contact piece 310 in the second conductor 350. Since the insertion part 120 is designed to be close to the end opening of the receiving cavity 110, the adapter piece 320 in the second conductor 350 needs to extend along the depth direction of the receiving cavity 110 to the bottom of the receiving cavity 110, thereby ensuring that the contact piece 310 in the second conductor 350 can be connected to the electrode of the battery 600. The inner wall of the receiving cavity 110 has a strip groove 111 to accommodate a portion of the adapter piece 320, allowing the adapter piece 320 to extend to the bottom of the cavity without affecting the volume of the battery 600.

[0067] The connection between the contact piece 310 of conductor 300 and the electrode of battery 600 can be achieved by welding, which ensures the connection strength while making the contact between the two more compact and more conducive to the conduction of current.

[0068] The conductor 300 has a through first flow channel 311 in the part used to connect the electrode. That is, the contact piece 310 has a first flow channel 311. In this way, during soldering, the first flow channel 311 provides a space for molten solder (such as solder paste). The solder can flow into and fill the first flow channel 311. Moreover, the first flow channel 311 can limit the disorderly flow of solder and prevent it from overflowing into the non-soldering area. The solder joint is more regular and controllable, reducing soldering defects such as cold solder joints and increasing the soldering strength between the conductor 300 and the electrode.

[0069] Of course, the conductor 300 and the battery 600 electrodes can also adopt screw-in, riveting or other structures, as long as they can be directly connected and fixed. This application does not make specific restrictions on the connection method.

[0070] In order to improve the above-mentioned defects, therefore, in this application, reference is made to Figure 2 , Figure 10 and Figure 11 The battery box also includes an elastic sleeve 500 fixed in the mounting hole 410; the elastic sleeve 500 is fitted over the extension 330 of the conductor 300, and a portion of the elastic sleeve 500 is recessed toward the conductor 300 to elastically resist the extension 330 of the conductor 300.

[0071] In this way, the elastic force provided by the elastic kit 500 can effectively fix the extended section 330 of the conductor 300 radially, improve the fixation stability, ensure the connection is durable, and the elastic support can ensure that the elastic kit 500 and the conductor 300 always maintain an effective electrical connection, improve electrical contact performance, reduce contact resistance, and improve current transmission efficiency. External electrical devices can be directly connected to the elastic kit 500, reducing the safety hazard of local overheating and fire caused by poor contact.

[0072] Understandably, both the elastic kit 500 and the conductor 300 are made of conductive materials, such as copper, aluminum, or stainless steel.

[0073] refer to Figure 12 and Figure 13 The elastic kit 500 includes two collars 510, a plurality of spring pieces 520 connected between the two collars 510, and a snap-fit ​​sleeve 530 connected to the collars 510; the collars 510 are sleeved outside the extension 330 of the conductor 300; each spring piece 520 is distributed circumferentially along the collars 510, and the spring pieces 520 are recessed toward the conductor 300 to elastically abut against the conductor 300; the snap-fit ​​sleeve 530 is fitted into the mounting hole 410.

[0074] Thus, the clip 530 is fitted into the mounting hole 410 as the fixing base for the entire elastic kit 500 and the connector 400, and the two collars 510 serve as fixing bases for the spring pieces 520, ensuring the stability and consistency of the force on the spring pieces 520. Multiple spring pieces 520 are evenly spaced along the circumference of the collars 510, forming an elastic cage surrounding the conductor 300. When the elastic kit 500 is installed, all spring pieces 520 simultaneously undergo elastic deformation inward (towards the conductor 300), applying a uniformly distributed radial pressure to the extended section 330 of the conductor 300. This circumferentially symmetrical clamping force ensures that the conductor 300 is stably centered, avoiding skewing, localized wear, or stress concentration that may result from single-point or asymmetrical force, providing the most stable and reliable clamping effect, effectively resisting loosening forces caused by vibration, thermal cycling, and mechanical impact, ensuring long-term stable connection, and reducing the risk of contact failure due to loosening.

[0075] The collar 510, spring 520, and retaining sleeve 530 are connected into a single integral structure (usually formed by stamping, injection molding, or welding). This integrated design avoids the fitting gaps and loosening risks that may occur when assembling multiple parts. The collar 510, acting as a supporting frame, effectively disperses the stress transmitted by the spring 520, preventing stress concentration and fatigue fracture at the root of the spring 520, and significantly improving the structural strength and cycle life of the elastic component 500 itself.

[0076] The spring 520 is arc-shaped, with its central part elastically abutting against the conductor 300. This reduces the friction between the conductor 300 and the spring 520 during the insertion of the conductor 300 extension 330 into the elastic kit 500, facilitating assembly. Furthermore, the central part of the spring 520, i.e., the arched top of the spring 520, serves as the main contact area with the extension 330. Under the same elastic force, the point / line contact can generate higher local contact pressure. This helps ensure effective electrical contact between the spring 520 and the conductor 300, improves electrical conductivity, avoids overload failure or insufficient preload, and provides stable clamping force.

[0077] Continue to refer to Figure 10 The portion of conductor 300 located within mounting hole 410 is cylindrical, meaning the extension 330 is cylindrical, and the collar 510 is annular. This creates an ideal concentric circle fit between the cylindrical extension 330 and the annular collar 510. Multiple elastic tabs 520 distributed along the circumference of the collar 510 can simultaneously and elastically abut against the outer circumferential surface of the extension 330, resulting in a more uniform force application to the extension 330. This provides all-around radial support for the extension 330, ensuring the stability and reliability of the clamping mechanism.

[0078] Of course, in some embodiments not shown, the spring 520 may also have a wavy or cantilevered structure, and the extension 330 may also have other shapes, such as a quadrangular prism, as long as it can provide elastic support for the extension 330.

[0079] The mounting sleeve 530 and the connector 400 can be fixed by a snap-fit ​​connection, for example, see reference. Figures 11 to 13 The mounting sleeve 530 has a snap fastener 531 and a slot 440 that communicates with the mounting hole 410. The snap fastener 531 engages with the slot 440. Thus, by aligning the elastic component 500 with the mounting hole 410 and applying axial force, the snap fastener 531 will elastically deform and pass through the hole. Once it enters the slot 440 area, it automatically springs back and locks. At the moment the snap fastener 531 successfully engages with the slot 440, the operator can usually clearly feel a sudden change in resistance (e.g., a "click" sound). This clear tactile and audible feedback allows the operator or automated equipment to tilt and confirm that the elastic component 500 is fully and correctly installed, effectively avoiding assembly defects such as omissions or incomplete installation, ensuring product consistency and reliability. Furthermore, it significantly shortens assembly time and greatly improves production efficiency; simultaneously, disassembly (repair or replacement) is relatively convenient, requiring only the use of a tool (such as a flathead screwdriver) to press the snap fastener 531 to disengage it from the slot 440.

[0080] Of course, in some embodiments, the mounting sleeve 530 can also be directly fixed to the connector 400 by means of adhesive bonding, interference fit between the hole and shaft, etc.

[0081] Continue to refer to Figures 11 to 13 The end of the retaining sleeve 530 away from the collar 510 is connected to a sealing piece 550 and a connecting piece 540. That is, the elastic kit 500 has a connecting piece 540. The sealing piece 550 covers the inner cavity of the retaining sleeve 530, and the connecting piece 540 extends radially outward from the retaining sleeve 530 to protrude from the side of the connector 400. The connecting piece 540 is used for electrical connection of electrical components. Thus, the end of the connecting piece 540 extends beyond the boundary of the entire connector 400, serving as a welding terminal to provide a convenient and reliable welding point for external electrical components, enabling reliable current transmission. When welding electrical components to the connecting piece 540, the sealing piece 550 acts as a physical barrier, preventing solder from entering the retaining sleeve 530, protecting the contaminated spring 520, collar 510, conductor 300 extension 330, and engaging structure, and preventing the solder from solidifying and jamming the spring 520, causing it to lose its elasticity.

[0082] The connector 540 is provided with a through second flow channel 541. During soldering, the second flow channel 541 provides a space for molten solder (e.g., solder paste). The solder can flow into and fill the second flow channel 541. Moreover, the second flow channel 541 can limit the disorderly flow of solder and prevent it from overflowing into non-soldering areas. The solder joints are more regular and controllable, reducing soldering defects such as cold solder joints and increasing the soldering strength between the electrical components and the connector 540.

[0083] Of course, it should be noted that the contact piece 310 of conductor 300 may not have the first shunt groove 311, for example... Figure 14 As shown, at this time, in order to ensure that the size of the contact piece 310 of the second conductor 350 can be manufactured in a way that is more precise than the required dimensions, the following steps are taken: Figure 8 The contact piece 310 of the second conductor 350 shown is larger in size to improve current transmission efficiency.

[0084] The shape of the extension 330 of conductor 300 is not limited. Figure 7 The hollow cylindrical shape is shown. In some embodiments, for example... Figure 15 As shown, at this time, the extended section 330 is in the shape of a bent stacked sheet, specifically, a double-layer structure formed by a single board being bent 180° once.

[0085] The length of the insertion portion 120 (i.e., the dimension along the depth direction of the receiving cavity 110) is not specifically limited, and is determined according to the installation height requirements of the connector 400, for example, in Figure 16 In this process, the length of the connector 120 can be made in proportion to... Figure 5 The length of the shown plug portion 120 is smaller. Furthermore, the slot 122 for mounting the adapter piece 320 of the second conductor 350 extends through the plug portion 120 to the side facing the connector 400. The through-slot 122 allows the installation status of the adapter piece 320 (e.g., whether it is in place, whether it is deformed) to be directly observed through the end face of the plug portion 120 or detected using a probe, facilitating quality control and troubleshooting. If replacement is needed, it can be directly pushed out from the mating surface, making maintenance convenient.

[0086] refer to Figure 17 In some embodiments, the side of the second conductor 350 away from the bottom of the receiving cavity 110 is spaced from the slot opening of the slot 122 to reduce the negative electrode transmission path.

[0087] The connector 400 itself can be as follows Figure 6 The unibody structure shown, such as one-piece injection molding, facilitates mass production. Of course, in some embodiments, such as... Figure 18 and Figure 19As shown, the connector 400 can also be a split structure. Specifically, the connector 400 has a sealing groove 470, and a mounting hole 410 penetrates the bottom of the sealing groove 470. A sealing plate 480 is riveted into the sealing groove 470 to press the elastic component 500 into the mounting hole 410, preventing the elastic component 500 from detaching from the mounting hole 410. The bottom of the sealing groove has a rivet post 471, and the sealing plate 480 is provided with corresponding clearance holes 481 to avoid the rivet post 471. The rivet post 471 serves as the positioning and load-bearing structure for the riveting connection. By providing clearance holes 481 at corresponding positions, the sealing plate 480 can smoothly fit into the sealing groove during installation, avoiding structural interference that could prevent installation or deformation caused by forced assembly. This clearance design ensures that riveting tools (such as rivet guns) can smoothly contact the rivet post 471 and complete operations such as pressing and pulling riveting, significantly improving assembly efficiency and process feasibility.

[0088] refer to Figure 20 In some embodiments, the guide hole 420 and the clearance groove 430 may not be provided on the connector 400, and the guide post 130 and the reinforcing rib 140 may not be provided on the corresponding plug-in part 120.

[0089] refer to Figure 21 In some embodiments, the sealing plate 550 may not be provided on the elastic kit 500. In addition, the width of the connecting piece 540 may be made smaller, and the second diversion groove 541 may not be provided accordingly.

[0090] refer to Figures 22 to 25 In some embodiments, the plug portion 120 may be a hollow structure, and a portion of the connector 400 may be hidden inside the plug portion 120, resulting in a better appearance.

[0091] In detail, the side of the plug portion 120 facing the connector 400 is provided with a mating groove 124;

[0092] The connector 400 includes a base plate 461 and a mating post 460 integrally connected to the base plate 461. The mating post 460 is provided with a mounting hole 410. The mating post 460 is inserted into the mating groove 124, and the base plate 461 is in contact with the insertion part 120.

[0093] Of course, it is understandable that in Figure 22 In this configuration, the number of mating posts 460 and mating grooves 124 is the same as the number of conductors 300, so that the extended sections 330 of the two conductors 300 can respectively extend into the elastic fittings 500 within the two mounting holes 410. Adjacent mating grooves 124 are separated by partitions 125.

[0094] In summary, the battery box disclosed in this application can not only shorten the connection path, reduce current transmission resistance and loss, and lower material costs, but also improve the fixing stability of conductor 300, ensure a durable connection, and improve current transmission efficiency.
