Detailed Implementation
[0052] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.
[0053] During battery production, the center-to-center distance between the positive and negative terminals needs to be compatible with the battery protection board and battery mounting interface. If the overall interface structure connecting to the battery protection board is changed during the development of new electronic devices, the structure of the battery protection board needs to be changed accordingly. This may alter the connection positions of the positive and negative terminals (i.e., change the center-to-center distance between them), requiring the redesign of the battery mold and significantly increasing development costs and time. Furthermore, in the development of a single project, if both the battery protection board and the battery mold need to be redesigned, and the resulting protection board exhibits poor heat dissipation or drop-resistance issues when used with a new battery, further development and adjustments are necessary, resulting in a longer development cycle and relatively higher costs.
[0054] Based on this, this disclosure provides a terminal adjustment assembly, in which the terminal is installed on a first adjustment unit and a second adjustment unit is installed on the battery casing. By adjusting the position of the first adjustment unit relative to the second adjustment unit, the installation position of the terminal can be adjusted, so as to adjust the distance between the positive and negative terminals of the battery according to the design of the battery protection board. It is not necessary to design a battery mold for each type of battery protection board. Only one battery mold is used, and the distance between the positive and negative terminals is adjusted by the terminal adjustment assembly, which can adapt to multiple types of battery protection boards, fully realize the reuse of battery mold, reduce the cost of battery development, and shorten the project research and development cycle.
[0055] refer to Figure 1 and Figure 2 An exemplary embodiment of this disclosure provides a pole adjustment assembly installed on a battery housing 10. The battery in this embodiment can be, for example, a steel-cased battery, which can be used in mobile terminals such as mobile phones to store electrical energy and power the mobile terminal. The battery housing 10 can be made of materials such as aluminum alloy or stainless steel.
[0056] refer to Figure 1 and Figure 2 The electrode adjustment assembly includes an electrode post 20, a first adjustment unit 100, and a second adjustment unit 200. The electrode post 20 is mounted on the first adjustment unit 100 and electrically connected to it. The second adjustment unit 200 is mounted on the battery casing 10 and is used for electrical connection to the cell tabs (not shown) inside the battery casing 10. Figure 2As shown, the battery casing 10 includes a middle frame 11, which has a first surface 12 (i.e., the surface located outside the battery) and a second surface 13 (i.e., the inner surface located inside the battery). The terminal posts 20 are located outside the battery casing 10, and the cell tabs are located inside the battery casing 10. Battery casing holes can be formed in the middle frame 11, through which conductive circuits can be designed to achieve electrical connection between the terminal posts 20 and the cell tabs.
[0057] In this embodiment, the first adjustment unit 100 is movable relative to the second adjustment unit 200 to adjust its position relative to the second adjustment unit 200. The first adjustment unit 100 and the second adjustment unit 200 are electrically connected to ensure that the terminal post 20 is electrically connected to the cell tab inside the battery casing 10. The structure of the first adjustment unit 100 and the second adjustment unit 200 is not specifically limited in this embodiment, as long as the position of the first adjustment unit 100 relative to the second adjustment unit 200 can be adjusted. For example, the first adjustment unit 100 can slide relative to the second adjustment unit 200 and be relatively fixed at a target position to achieve electrical connection; or, for example, the first adjustment unit 100 and the second adjustment unit 200 are detachably connected, and the second adjustment unit 200 has multiple mounting positions, allowing the first adjustment unit 100 to be installed in different mounting positions according to design requirements.
[0058] In this embodiment, as Figure 1 As shown, the second adjustment unit 200 is fixed relative to the battery housing 10, and the first adjustment unit 100 can move relative to the second adjustment unit 200 and be fixed at the target position. Therefore, when the position of the first adjustment unit 100 relative to the second adjustment unit 200 changes, the position of the first adjustment unit 100 relative to the battery housing 10 also changes accordingly, so as to achieve the purpose of adjusting the position of the terminal post 20.
[0059] For example, both the first adjustment unit 100 and the second adjustment unit 200 can be mounted on the battery housing 10, wherein the first adjustment unit 100 is movably connected to the battery housing 10, and the second adjustment unit 200 is fixedly connected to the battery housing 10, so that the first adjustment unit 100 can move relative to the second adjustment unit 200. Of course, both the first adjustment unit 100 and the second adjustment unit 200 can also be movably mounted on the battery housing 10, as long as the second adjustment unit 200 is always electrically connected to the cell tab.
[0060] This disclosure uses a first adjustment unit and a second adjustment unit to adjust the installation position of the terminals, so as to adjust the distance between the positive and negative terminals of the battery according to the design of the battery protection board. This eliminates the need to design a battery mold for each type of battery protection board, which helps to reduce the cost of battery development.
[0061] Furthermore, since batteries processed from the same battery mold can adapt to various types of battery protection boards by changing the distance between the positive and negative terminals using the terminal adjustment component, when the types of battery protection boards for various models of electronic devices are relatively fixed, such as when a manufacturer selects one of four battery protection boards for various signal mobile phones, the battery can also be produced using existing battery molds. In this case, both the battery protection board and the battery are relatively mature, and the probability of heat dissipation and reliability issues is relatively low. Compared to redesigning the battery protection board and battery mold for each project, this approach can effectively reduce problems such as poor heat dissipation and poor drop reliability caused by redesigning the battery protection board for a single project (i.e., both the battery protection board and battery mold are redesigned), thus shortening the design cycle and improving design reliability.
[0062] In one exemplary embodiment, reference Figures 1 to 4 The first adjustment unit 100 includes a first connecting portion, and the second adjustment unit 200 includes a second connecting portion. One of the first and second connecting portions is a slot, and the other is a locking portion 120. The slot has multiple slots 2111, and the locking portion 120 can engage with the slots 2111 to limit the movement of the first adjustment unit 100 and the second adjustment unit 200. Under external force (e.g., applying a thrust to the pole 20 connected to the first adjustment unit 100), the locking portion 120 can disengage from one slot 2111 of the slot and move to an adjacent slot 2111, engaging therewith. The number of slots 2111 and the number of locking portions 120 can be set as needed, as long as the locking portion 120 can disengage from its corresponding slot 2111 and move to an adjacent slot 2111.
[0063] In one example, such as Figures 1 to 4 As shown, the first connecting part is a slot, and the second connecting part is a latching part 120; in another example, the first connecting part is a latching part 120, and the second connecting part is a slot. The latching part 120 can form a mating relationship with each of the multiple slots 2111 of the slot. Thus, by moving the latching part 120, the latching part 120 can move from one slot 2111 of the slot to an adjacent slot 2111, thereby realizing the movement and limiting of the first adjusting unit 100 relative to the second adjusting unit 200.
[0064] For example, the shape of the slot 2111 and the shape of the latching part 120 can be set as needed, as long as the latching part 120 can be latched into the slot 2111 when not moving and can be disengaged from the slot 2111 to the adjacent slot 2111 when moving. For example, the shape of the slot 2111 can be a semi-circular arc, an elliptical arc, an isosceles trapezoid, a crescent shape, etc.; the shape of the latching part 120 can be a semi-circular arc, an elliptical arc, an isosceles trapezoid, a hook shape, etc.
[0065] For example, the shape of the latching part 120 needs to be the same as the shape of the slot 2111. In this way, the latching part 120 can fill the entire slot 2111, which is beneficial to the latching reliability between the latching part 120 and the slot 2111. Of course, the shape of the latching part 120 can also be different from the shape of the slot 2111, as long as the latching part 120 can move to the adjacent slot 2111 and lock in place.
[0066] For example, the number of slots 2111 and the distance between adjacent slots 2111 can be set as needed, as long as the snap-fit part 120 can be disengaged from the slot 2111 and move to the adjacent slot 2111.
[0067] In an exemplary embodiment, a snap-fit portion 120 or a slot may also be provided on the end of the pole post 20 near the inside of the battery (i.e., the end portion of the pole post), that is, one of the end portion of the pole post 20 and the second connecting portion is a slot, and the other is a snap-fit portion 120, thereby realizing the adjustment of the installation position of the pole post 20.
[0068] In other possible embodiments, one of the first connecting part and the second connecting part may be a groove, and the other may be a sliding protrusion. The groove forms a track, and the sliding protrusion can move along the track, thereby ensuring the electrical connection between the first connecting part and the second connecting part while adjusting the position of the first connecting part relative to the second connecting part, and thus adjusting the position of the first adjusting unit 100 relative to the second adjusting unit 200.
[0069] In one exemplary embodiment, reference Figure 3 and Figure 4The first adjustment unit 100 includes a slider 130, which includes a body 131 and a snap-fit portion 120 protruding from the edge of the body 131. The terminal post adjustment assembly includes a first adjustment bracket 30, which, exemplarily, can be integrally molded into the battery casing 10 by in-mold injection molding. The first adjustment bracket 30 is provided with a first mounting area 37, and the slider 130 is mounted in the first mounting area 37. The first mounting area 37 is provided with a plurality of slots 2111. Under external force, the snap-fit portion 120 undergoes elastic deformation to move between adjacent slots 2111 in the first mounting area 37. During the movement of the slider 130 in the first mounting area 37 under external force, the slight deformation of the snap-fit portion 120 at the edge of the slider 130 can be recovered without affecting the snap-fit limit between the snap-fit portion 120 and the slot 2111.
[0070] The first adjusting bracket 30 includes a first side and a second side facing each other, and multiple slots 2111 are provided on both sides. The slider 130 also includes a first side and a second side facing each other, and a locking part 120 is provided on both sides. The first side of the slider 130 contacts the first side of the first adjusting bracket 30, and the second side of the slider 130 contacts the second side of the first adjusting bracket 30. When the positions of the slider 130 and the first adjusting bracket 30 are relatively fixed, the locking part 120 of the first side of the slider 130 engages with the slot 2111 on the first side of the first adjusting bracket 30, and the locking part 120 of the second side of the slider 130 engages with the slot 2111 on the second side of the first adjusting bracket 30, thereby ensuring more reliable positioning. It is understood that when the multiple slots 2111 are only provided on the first side or the second side of the first adjusting bracket 30, the locking part 120 is only provided on the first side or the second side of the slider 130.
[0071] In one embodiment, reference Figure 4 The slider 130 has a rectangular body 131, with a snap-fit portion 120 protruding from the body 131 along its width. Along the length of the body 131, two snap-fit portions 120 are provided on each long side. The slot includes two sets of first slot groups arranged opposite each other, each first slot group corresponding to the long side, and each first slot group includes multiple slots 2111. In the assembled state, the two snap-fit portions 120 on each long side of the body 131 snap into the two spaced-apart slots 2111. For example, the two snap-fit portions 120 on one long side snap into the slot 2111 located at the first position and the slot 2111 located at the third position, respectively.
[0072] In this embodiment, as Figure 4As shown, multiple slots 2111 are provided on both the first and second sides of the first mounting area 37. For example, five slots 2111 for accommodating the snap-fit parts 120 are provided on both the first and second sides of the first mounting area 37. Correspondingly, two snap-fit parts 120 are provided on both the first and second sides of the slide 130. The two snap-fit parts 120 can be snapped into the slots 2111 located at the second and fourth positions, respectively. In this way, by providing multiple snap-fit parts 120 and multiple slots 2111 to match, the connection reliability between the slide 130 and the first adjusting bracket 30 can be improved. It is understood that when the two snap-fit parts 120 move into the slots 2111 located at the first and third positions, the slide 130 still remains in contact with the conductive seal 40 (described in detail later).
[0073] In other possible embodiments, the number of latching portions 120 provided on the two long sides of the body 131 of the slider 130 may be different. For example, two latching portions 120 may be provided on one long side, and in the assembled state, the two latching portions 120 are respectively latched into the slots 2111 located at the second position and the fourth position. The other long side may only have one latching portion 120, and in the assembled state, the latching portion 120 is latched into the slot 2111 located at the third position.
[0074] In one exemplary embodiment, reference Figures 2 to 5 The first adjusting bracket 30 includes an insulating body and a conductive layer 34 disposed on the insulating body. The conductive layer 34 can be formed in the first adjusting bracket 30 by injection molding. Alternatively, a slot adapted to the conductive layer 34 can be formed on the first adjusting bracket 30, and the conductive layer 34 can be disposed in the slot and located in the inner surface of the slot. The insulating body is used to insulate the terminal post 20 and the slider 130 from the battery casing 10, preventing short circuits due to contact between the terminal post 20 and the slider 130 and the battery casing 10. The conductive layer 34 includes a first conductive region extending to the slot 2111. The slider 130 is made of a conductive material, such as silver, copper, gold, or other metals with good conductivity. It can also be made of other materials with good conductivity, such as conductive ceramics. In the assembled state, the slider 130 is electrically connected to the first conductive region and the terminal post 20. The pole post 20 can be fixedly connected to the slide plate 130 by means of riveting, screwing or laser welding.
[0075] In this embodiment, combined with Figure 3 and Figure 4The insulating body of the first adjusting bracket 30 forms the first mounting area 37. The slider 130 is mounted in the first mounting area 37. The slot 2111 is set in the first mounting area 37. The first conductive area extends to the slot 2111, so that the slider 130 can always maintain electrical connection with the first conductive area when it moves in the first mounting area 37.
[0076] For example, the first conductive region can cover the entire surface of the slot 2111. Of course, it can also cover part of the surface of the slot 2111. For example, the first conductive region only covers the part of the surface that contacts the slot 2111 when the slider 130 moves, as long as the slider 130 can be electrically connected to the first conductive region when it moves between the slots 2111.
[0077] In one embodiment, reference Figure 3 The electrode adjustment assembly also includes a conductive seal 40, which can be, for example, a conductive screw, pin, or stud. The second adjustment unit 200 also includes a first conductive connector 220. The first conductive connector 220 is used to electrically connect the conductive seal 40 to the battery cell tab. The first conductive connector 220 can be, for example, a metal plate welded to the battery cell tab. The conductive seal 40 is used to fix the first adjustment bracket 30 and the first conductive connector 220 to the battery casing 10. The first adjustment bracket 30 has a mounting hole (not shown in the figure). The conductive layer 34 includes a second conductive region electrically connected to the first conductive region. The second conductive region extends to the inner surface of the mounting hole and is electrically connected to the conductive seal 40, so that the conductive layer 34 is electrically connected to the first conductive connector 220. The second conductive region can cover the entire inner surface of the mounting hole, or it can cover only a portion of the inner surface of the mounting hole, as long as the second conductive region is electrically connected to the conductive seal 40.
[0078] In this embodiment, as Figure 3As shown, the insulating body of the first adjusting bracket 30 includes a first body 31, a second body 32, and a connecting portion (not shown) connecting the first body 31 and the second body 32. The first body 31 is disposed on the first surface 12 of the middle frame 11, and the second body 32 is disposed on the second surface 13 of the middle frame 11. The connecting portion passes through the battery housing hole to connect the first body 31 and the second body 32. The first body 31 and the second body 32 are respectively provided with through holes, and the connecting portion is provided with a connecting hole (not shown) passing through the two through holes. This connecting hole and the two through holes constitute the mounting hole of the first adjusting bracket 30. The conductive seal 40 can pass through this mounting hole to fix the first adjusting bracket 30 to the battery housing 10. For example, the position of the mounting hole can be set as needed, as long as it ensures that the slider 130 is always electrically connected to the conductive seal 40 when sliding. For example, the mounting hole can be located in the middle of the first adjusting bracket 30.
[0079] The first conductive connector 220 is disposed on the side of the second body 32 away from the second surface 13, ensuring insulation between the first conductive connector 220 and the battery casing 10. The first conductive connector 220 also has a first conductive connection hole corresponding to the mounting hole. The conductive seal 40 can pass through the mounting hole and the first conductive connection hole to fix the first adjusting bracket 30 and the first conductive connector 220 to the battery casing 10. Furthermore, the conductive seal 40 is electrically connected to a second conductive area extending to the inner surface of the mounting hole, enabling not only electrical connections between the electrode post 20, the slider 130, the conductive layer 34, the conductive seal 40, the first conductive connector 220, and the battery cell tabs, but also sealing between the first adjusting bracket 30 and the battery casing 10.
[0080] For example, the material of the first conductive connector 220 can be aluminum, copper, etc. It can be understood that when the corresponding cell tab is the positive electrode, the material of the first conductive connector 220 can be aluminum, and when the corresponding cell tab is the negative electrode, the material of the first conductive connector 220 can be copper. In this way, the first conductive connector 220 is the same as the metal material corresponding to the positive and negative electrode sheets, which can ensure that the quality of the battery is not affected.
[0081] In an exemplary embodiment, a conductive plate matching the first mounting area 37 can be provided in the first adjusting bracket 30. The conductive plate may include a conductive cover plate and a plurality of grooves disposed on the edge of the conductive cover plate. The plurality of grooves correspond one-to-one with a plurality of slots 2111 in the first mounting area 37, and the grooves can fit into the slots 2111. The grooves constitute the first conductive area. The conductive cover plate is provided with conductive cover plate holes corresponding to the mounting holes. The inner surface of the conductive cover plate holes constitutes the second conductive area. When the conductive seal 40 passes through the conductive cover plate holes, it contacts the hole wall of the conductive cover plate holes, thereby realizing the electrical connection between the conductive seal 40 and the conductive plate.
[0082] In other possible embodiments, the conductive seal 40 can be in direct contact with the slider 130, so that the slider 130 can always be electrically connected to the conductive seal 40 when it moves in the first mounting area 37. In this way, the conductive layer 34 can be eliminated to achieve the electrical connection of the pole post 20, the slider 130, the conductive seal 40, the first conductive connector 220, and the battery cell tab. The structure is simple and easy to manufacture.
[0083] Regarding the technical content involved in the above embodiments, this disclosure provides structures such as a sliding plate, a first adjusting bracket, a conductive layer, a conductive seal, and a first conductive connector. When the above structures are in the assembled state, the pole post and the sliding plate form an electrical connection, the edge of the sliding plate is electrically connected to the conductive layer in the groove of the first adjusting bracket, and then the conductive layer is electrically connected to the conductive seal through the second conductive area of the conductive layer. The conductive seal is electrically connected to the first conductive connector, and the first conductive connector is electrically connected to the battery cell tab, thereby realizing the electrical connection between the pole post and the battery cell tab.
[0084] In another exemplary embodiment of this disclosure, reference is made to Figures 6 to 9 The first adjustment unit 100 includes an adjustment assembly having a receiving area 3301, in which a pole post 20 is installed. The pole post 20 can be connected to the adjustment assembly by injection molding to form a slider 330. Alternatively, a groove can be provided in the slider 330 to embed the pole post 20 therein. The adjustment assembly also includes an insulated gripper 310, with a locking portion 120 at its end. A first conductive portion is provided inside the gripper 310, extending to the surface of the locking portion 120. This allows for electrical connection between the locking portion 120 and the inside of the gripper 310.
[0085] In other embodiments, the gripper 310 can also be configured as a conductor, so that the electrical connection between the gripper 310 and the latching part 120 can be achieved without the need to provide a first conductive part.
[0086] In one embodiment, reference Figure 7 The adjustment assembly includes a slider 330 and a sliding cover plate 340. The slider 330 is provided with a receiving area 3301, and the sliding cover plate 340 is provided with a gripper 310. The slider 330 is provided with a first connecting part 331, and the sliding cover plate 340 is provided with a second connecting part 341. The first connecting part 331 can be engaged with the second connecting part 341 to connect the slider 330 and the sliding cover plate 340.
[0087] like Figure 7As shown, the slider 330 and the sliding cover 340 are respectively disposed on the first surface 12 and the second surface 13 of the battery housing 10. The slider 330 is provided with a first mating structure, namely the first connecting part 331, on the side facing the sliding cover 340, and the sliding cover 340 is provided with a second mating structure, namely the second connecting part 341, on the side facing the slider 330. The first mating structure can cooperate with the second mating structure to achieve a snap-fit.
[0088] For example, one of the first and second mating structures is a protrusion, and the other is a groove. Thus, the protrusion can engage with the groove to achieve a fixed connection between the slider 330 and the sliding cover 340. Alternatively, both the first and second mating structures can be grooves; that is, the first mating structure has a first groove, and the second mating structure has a second groove. The first groove can be inserted into the second groove, or the second groove can be inserted into the first groove to achieve a snap-fit, thereby achieving a fixed connection between the slider 330 and the sliding cover 340.
[0089] Of course, in other embodiments, the slider 330 and the sliding cover 340 can be an integral structure. The slider 330 and the sliding cover 340 can be made of insulating materials such as plastic, rubber, etc., thereby achieving insulation between the terminal post 20 and the battery casing 10.
[0090] In one exemplary embodiment, reference continues to be made to Figure 7 The first connecting part 331 is provided with a second conductive part, which is electrically connected to the pole post 20. The second connecting part 341 is provided with a third conductive part, which is electrically connected to the first conductive part. When the first connecting part 331 and the second connecting part 341 are snapped together, the second conductive part and the third conductive part are electrically connected.
[0091] In this embodiment, by providing a second conductive part and a third conductive part, an electrical connection can be achieved between the pole post 20, the second conductive part, the third conductive part, the first conductive part, and the snap-fit part 120.
[0092] In a possible embodiment, when the first connecting portion 331 is a protrusion or has a first groove, and the second connecting portion 341 has a second groove, a metal conductive layer 34 is coated on the outer sidewall of the first connecting portion 331, and a metal conductive layer 34 is coated on the inner sidewall of the second connecting portion 341. This ensures that the first connecting portion 331 and the second connecting portion 341 are electrically connected in a snap-fit state. Of course, both the first connecting portion 331 and the second connecting portion 341 can be metal conductors.
[0093] In one embodiment, reference Figure 7 and Figure 9The pole adjustment assembly includes a second adjustment bracket 50, which has a second mounting area 501 in which the adjustment assembly is installed. The second mounting area 501 has a guide area (not shown in the figure), and a first connecting part 331 and a second connecting part 341 are installed in the guide area. Under the action of an external force (such as applying a pushing force to the slider 330 on which the pole 20 is installed), the first connecting part 331 and the second connecting part 341 can move along the guide area.
[0094] In this embodiment, combined with Figure 7 and Figure 9 The second adjusting bracket 50 includes an upper adjusting bracket body 51, a lower adjusting bracket body 52, and a connecting body (not shown in the figure). The connecting body connects the upper adjusting bracket body 51 and the lower adjusting bracket body 52. The upper adjusting bracket body 51 is located on the first surface 12 of the battery housing 10, the lower adjusting bracket body 52 is located on the second surface 13 of the battery housing 10, and the connecting body is located in a hole in the battery housing. The upper adjusting bracket body 51 has a first receiving groove for receiving a slider 330, and the lower adjusting bracket body 52 has a second receiving groove for receiving a sliding cover plate 340. The connecting body has a connecting body mounting hole. Thus, the first receiving groove, the second receiving groove, and the connecting body hole constitute a second mounting area 501, and the connecting body mounting hole constitutes a guide area, allowing the first connecting part 331 and the second connecting part 341 to move within the connecting body mounting hole. The connecting body mounting hole penetrates the upper adjusting bracket body 51 and the lower adjusting bracket body 52 to connect the first receiving groove and the second receiving groove. In the assembled state, the first connecting part 331 and the second connecting part 341 move in the mounting hole of the connecting body, thereby driving the slider 330 and the sliding cover plate 340 to move in the first receiving groove and the second receiving groove respectively, thereby realizing the adjustment of the installation position of the pole post 20.
[0095] Of course, in other embodiments, the upper body 51, the connecting body, and the lower body 52 of the second adjustment bracket can also be separate structures, and they can be fixedly connected by means of adhesive, threaded connection, etc.
[0096] In one exemplary embodiment, reference Figure 8 The sliding cover 340 is composed of a cover body 342, a second connecting part 341 protruding from the surface of the cover body 342, and two grippers 310 connected to the side surface of the cover body 342. The second connecting part 341 is provided with a third conductive part, the end of the gripper 310 is provided with a snap-fit part 120, the inside of the gripper 310 is provided with a first conductive part, and the inside of the cover body 342 is provided with a fourth conductive part, which electrically connects the third conductive part and the first conductive part.
[0097] In one exemplary embodiment, reference Figure 7 and Figure 9 The second adjustment unit 200 also includes a second conductive connector 230, which is disposed on the second adjustment bracket 50. The second conductive connector 230 includes two sets of second slots arranged symmetrically. The second slots are corresponding to the clamping arms of the gripper 310. Each set of second slots includes multiple slots 2111.
[0098] Combination Figure 7 and Figure 9 A second conductive connector 230 is also provided on the lower body 52 of the second adjustment bracket. The second conductive connector 230 is electrically connected to the battery cell tab, and the second conductive connector 230 is also provided with a plurality of slots 2111 that cooperate with the snap-fit part 120. The movable slider 330 and the gripper 310 of the sliding cover 340 can move relative to the second slot group. The snap-fit part 120 at the end of the gripper 310 can snap into one of the slots 2111 and can be released to the adjacent slot 2111. In this way, while realizing the electrical connection between the terminal 20 and the cell tab, the installation position of the terminal 20 can also be adjusted so that the distance between the positive and negative terminals of the battery can be adjusted according to the design of the battery protection board. It is not necessary to design a battery mold for each type of battery protection board. Only one battery mold is used and the distance between the positive and negative terminals is adjusted by the terminal adjustment component. This can adapt to multiple types of battery protection boards, fully realize the reuse of battery mold, reduce the cost of battery development, and shorten the project development cycle.
[0099] For example, the second conductive connector 230 can be fixed to the second adjusting bracket 50 by injection molding. Alternatively, a groove can be formed on the second adjusting bracket 50 to embed the second conductive connector 230 into the groove. The second conductive connector 230 can be, for example, a metal plate welded to the battery cell tab.
[0100] In one exemplary embodiment, reference Figure 8 and Figure 9 The second conductive connector 230 includes an elongated structure and slots extending from both ends of the elongated structure in the width direction. The two slots are arranged opposite to each other, and each slot includes multiple slots 2111. The elongated structure of the second conductive connector 230 can be exposed above the second adjusting bracket 50 to facilitate electrical connection between the second conductive connector 230 and the battery cell tab.
[0101] In one exemplary embodiment, reference is made to Figure 7A first sealing ring 410 can be provided between the first connecting part 331 and the second connecting part 341 to achieve a seal between the first connecting part 331 and the second connecting part 341; or a second sealing ring 420 can be provided between the sliding cover plate 340 and the second adjusting bracket 50 to achieve a seal between the sliding cover plate 340 and the second adjusting bracket 50; or a third sealing ring 430 can be provided between the slider 330 and the battery housing 10 to achieve a seal between the slider 330 and the battery housing 10. That is, sealing rings can be provided at the above three locations to ensure the sealing effect of the structure.
[0102] The technical content involved in the above solution, this disclosure, through the setting of a slider, a sliding cover plate, a second adjusting bracket, a gripper, a second conductive connector, etc., when the above structures are in the assembled state, the pole post and the second conductive part of the first connecting part on the slider are electrically connected, the second conductive part and the third conductive part of the second connecting part on the sliding cover plate are electrically connected, and then the third conductive part is electrically connected to the first conductive part inside the gripper, the first conductive part is electrically connected to the snap-fit part at the end of the gripper, the snap-fit part is electrically connected to the second conductive connector, and the second conductive connector is electrically connected to the battery cell tab, thereby realizing the electrical connection between the pole post and the battery cell tab.
[0103] An exemplary embodiment of this disclosure provides a battery including a battery casing, a positive terminal, and a negative terminal. The positive terminal and / or the negative terminal are mounted on the battery casing via a terminal adjustment assembly, i.e., one of the positive and negative terminals corresponds to one terminal adjustment assembly, or each of the positive and negative terminals can correspond to a separate terminal adjustment assembly to adjust the distance between the positive and negative terminals. Thus, by setting the terminal adjustment assembly to adjust the installation position of the terminals, the distance between the positive and negative terminals of the battery can be adjusted according to the design of the battery protection board. This eliminates the need to design a separate battery mold for each type of battery protection board; only one battery mold is needed, and the distance between the positive and negative terminals can be adjusted using the terminal adjustment assembly. This allows for the adaptation to multiple types of battery protection boards, fully realizing the reuse of the battery mold, reducing battery development costs, and shortening the project development cycle.
[0104] In one exemplary embodiment, reference is made to Figure 7 When both the positive and negative terminals correspond to the terminal adjustment assembly, the second adjustment bracket corresponding to the positive terminal can be an integral structure with the second adjustment bracket corresponding to the negative terminal. That is, the upper body of the second adjustment bracket can be provided with two first receiving slots at intervals, and the lower body of the second adjustment bracket can be provided with two second receiving slots at intervals, with each of the two first receiving slots corresponding to one of the two second receiving slots.
[0105] An exemplary embodiment of this disclosure provides an electronic device including the battery described above. The electronic device includes a battery mounting interface and a battery protection board connected to the battery mounting interface. A terminal adjustment assembly adjusts the distance between the positive and negative terminals of the battery to adapt to the battery protection board. Thus, it is unnecessary to design a separate battery mold for each type of battery protection board. Only one battery mold is needed, and the distance between the positive and negative terminals can be adjusted using the terminal adjustment assembly to adapt to multiple types of battery protection boards. This fully realizes the reuse of the battery mold, which helps reduce battery development costs and shortens the project's R&D cycle.
[0106] For example, electronic devices can be mobile devices such as mobile phones, tablets, laptops, handheld computers, in-vehicle electronic devices, wearable devices, ultra-mobile personal computers (UMPCs), netbooks, or personal digital assistants (PDAs), as well as non-mobile devices such as personal computers (PCs), televisions (TVs), ATMs, or self-service machines.
