DETAILED DESCRIPTION

[0052] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0053] During the battery production process, the center distance between the positive and negative poles of the battery needs to be adapted to the battery protection board and the battery installation interface. If the new electronic equipment changes the overall interface structure connected to the battery protection board during the research and development process, the structure of the battery protection board needs to be changed accordingly, which may cause the position of the connection with the positive and negative poles of the battery to change (that is, the center distance between the positive and negative poles is changed). In this case, the battery mold needs to be redeveloped and designed, resulting in a significant increase in research and development costs and cycles. In addition, during the research and development of a single project, if the battery protection board is redeveloped and the battery mold also needs to be redeveloped, once the developed battery protection board has problems such as poor heat dissipation and poor drop reliability when used with the new battery, it needs to be redeveloped and adjusted, and the research and development cycle is long and the research and development costs are relatively high.

[0054] Based on this, the present disclosure provides a pole adjustment assembly, in which the pole is installed on a first adjustment unit, and the second adjustment unit is installed on a battery housing. By adjusting the position of the first adjustment unit relative to the second adjustment unit, the installation position of the pole can be adjusted, so as to adjust the distance between the positive pole and the negative pole of the battery according to the design of the battery protection board. There is no need to design a set of battery molds for each type of battery protection board. Only one set of battery molds is used and the distance between the positive pole and the negative pole is adjusted through the pole adjustment assembly. It can adapt to various types of battery protection boards, fully realize the reuse of battery molds, which is beneficial to reduce the cost of battery development, and at the same time can shorten the research and development cycle of the project.

[0055] refer to Figure 1 and Figure 2 An exemplary embodiment of the present disclosure provides a pole adjustment assembly, which is installed in a battery housing 10. The battery in this embodiment may be a steel shell battery, which may be applied to mobile terminals such as mobile phones to store electrical energy for powering the mobile terminals. The material of the battery housing 10 may be aluminum alloy, stainless steel, etc.

[0056] refer to Figure 1 and Figure 2 The pole adjustment assembly includes a pole 20, a first adjustment unit 100 and a second adjustment unit 200. The pole 20 is installed on the first adjustment unit 100, and the pole 20 is electrically connected to the first adjustment unit 100. The second adjustment unit 200 is installed on the battery housing 10, and the second adjustment unit 200 is used to be electrically connected to the battery cell tab (not shown in the figure) inside the battery housing 10. Figure 2As shown, the battery case 10 includes a middle frame 11, the middle frame 11 has an opposite first surface 12 (i.e., a surface located outside the battery) and a second surface 13 (i.e., an inner surface located inside the battery), the pole 20 is located outside the battery case 10, and the battery cell tab is located inside the battery case 10. A battery shell hole can be opened on the middle frame 11, and the conductive circuit can be designed through the battery shell hole to achieve electrical connection between the pole 20 and the battery cell tab.

[0057] The first adjusting unit 100 can move relative to the second adjusting unit 200 to adjust the position of the first adjusting unit 100 relative to the second adjusting unit 200, and the first adjusting unit 100 is electrically connected to the second adjusting unit 200, so that the pole 20 is electrically connected to the battery cell tab inside the battery housing 10. The structures of the first adjusting unit 100 and the second adjusting unit 200 are not specifically limited in this embodiment, as long as the first adjusting unit 100 can be adjusted relative to the position of the second adjusting unit 200, for example, the first adjusting unit 100 can slide relative to the second adjusting unit 200 and be relatively fixed at the target position and achieve electrical connection; for another example, the first adjusting unit 100 and the second adjusting unit 200 are detachably connected, and multiple installation positions are set on the second adjusting unit 200, and the first adjusting unit 100 can be installed in different installation positions according to design requirements.

[0058] In this embodiment, Figure 1 As shown, the second adjusting unit 200 is fixed relative to the battery housing 10, and the first adjusting unit 100 can move relative to the second adjusting unit 200 and be fixed at the target position. Therefore, when the position of the first adjusting unit 100 relative to the second adjusting unit 200 changes, the position of the first adjusting unit 100 relative to the battery housing 10 also changes accordingly, so as to achieve the purpose of adjusting the position of the pole 20.

[0059] Exemplarily, the first adjustment unit 100 and the second adjustment unit 200 may both 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, the first adjustment unit 100 and the second adjustment unit 200 may also both be movably mounted on the battery housing 10, as long as the second adjustment unit 200 is always electrically connected to the battery cell tab.

[0060] The present invention adjusts the installation position of the pole by cooperating with the first adjustment unit and the second adjustment unit, so as to adjust the distance between the positive pole and the negative pole of the battery according to the design of the battery protection board. There is no need to design a set of battery molds for each type of battery protection board, which is conducive to reducing the cost of battery development.

[0061] In addition, since the batteries processed by the same battery mold can adapt to various types of battery protection boards by changing the distance between the positive and negative poles through the pole adjustment assembly, when the types of battery protection boards of various models of electronic equipment are relatively fixed, for example, a manufacturer produces various signal mobile phones and chooses one from four battery protection boards, the battery can also be produced using existing battery molds. At this time, both the battery protection board and the battery are relatively mature, and the probability of heat dissipation and reliability problems is small. Compared with the method of redesigning the battery protection board and battery mold for each project, it can effectively reduce the problems of poor heat dissipation and poor drop reliability of the battery protection board in the design process due to a single project (that is, the battery protection board and the battery mold are redesigned), shorten the design cycle, and improve design reliability.

[0062] In an exemplary embodiment, reference Figures 1 to 4 , the first adjustment unit 100 includes a first connection part, the second adjustment unit 200 includes a second connection part, one of the first connection part and the second connection part is a card slot, and the other of the two is a clamping part 120. The card slot is provided with a plurality of slots 2111, and the clamping part 120 can be clamped into the slots 2111 to limit the first adjustment unit 100 and the second adjustment unit 200. Under the action of external force (such as applying a thrust to the pole 20 connected to the first adjustment unit 100), the clamping part 120 can be disengaged from one of the slots 2111 in the card slot and move to the adjacent slot 2111 and clamped therein. Among them, the number of slots 2111 and the number of clamping parts 120 can be set as needed, as long as it is ensured that the clamping part 120 can be disengaged from the corresponding slot 2111 and move to the adjacent slot 2111.

[0063] In one example, if Figures 1 to 4 As shown, if the first connection part is a card slot, the second connection part is a clamping part 120; in another example, if the first connection part is a clamping part 120, the second connection part is a card slot. The clamping part 120 can form a matching relationship with each of the multiple slots 2111 of the card slot, so that by moving the clamping part 120, the clamping part 120 can move from one of the slots 2111 of the card slot to the adjacent slot 2111, thereby realizing the movement and limitation of the first adjustment unit 100 relative to the second adjustment unit 200.

[0064] Exemplarily, the shape of the slot 2111 and the shape of the clamping portion 120 can be set as needed, as long as it is ensured that the clamping portion 120 can be inserted into the slot 2111 when not moving, and can be released from the slot 2111 to the adjacent slot 2111 when moving. For example, the shape of the slot 2111 can be a semicircular arc, an elliptical arc, an isosceles trapezoid, a crescent shape, etc.; the shape of the clamping portion 120 can be a semicircular arc, an elliptical arc, an isosceles trapezoid, a hook shape, etc.

[0065] Exemplarily, the shape of the clamping portion 120 needs to be the same as the shape of the slot 2111, so that the clamping portion 120 can occupy the entire slot 2111, which is beneficial to the clamping reliability between the clamping portion 120 and the slot 2111. Of course, the shape of the clamping portion 120 can also be different from the shape of the slot 2111, as long as the clamping portion 120 can move to the adjacent slot 2111 and get stuck.

[0066] Illustratively, the number of slots 2111 and the distances between adjacent slots 2111 can be set as needed, as long as it is ensured that the engaging portion 120 can escape from a slot 2111 and move to an adjacent slot 2111 .

[0067] In an exemplary embodiment, a snap-on portion 120 or a slot may also be provided on the end of the pole 20 close to the interior of the battery (i.e., the terminal end of the pole), that is, one of the terminal end of the pole 20 and the second connecting portion is a slot, and the other is a snap-on portion 120, thereby achieving adjustment of the installation position of the pole 20.

[0068] In other possible embodiments, one of the first connecting part and the second connecting part may also be a slide groove, and the other one may be a sliding protrusion. The slide groove constitutes a track, and the sliding protrusion can move along the track, thereby ensuring that the first connecting part and the second connecting part are electrically connected while also being able to adjust the position of the first connecting part relative to the second connecting part, thereby adjusting the position of the first adjustment unit 100 relative to the second adjustment unit 200.

[0069] In an exemplary embodiment, reference Figure 3 and Figure 4, the first adjustment unit 100 includes a slide 130, and the slide 130 includes a body 131 and a clamping portion 120 protruding from the edge of the body 131. The pole adjustment assembly includes a first adjustment bracket 30, and illustratively, the first adjustment bracket 30 can be integrally formed in the battery housing 10 by in-mold injection. The first adjustment bracket 30 is provided with a first mounting area 37, and the slide 130 is installed in the first mounting area 37, and the first mounting area 37 is provided with a plurality of slots 2111. Under the application of external force, the clamping portion 120 generates elastic deformation to move between adjacent slots 2111 in the first mounting area 37. During the movement of the slide 130 in the first mounting area 37 under the action of external force, the clamping portion 120 at the edge of the slide 130 undergoes slight deformation and can be restored, which will not affect the clamping limit between the clamping portion 120 and the slot 2111.

[0070] The first adjustment bracket 30 includes a first side and a second side opposite to each other, and a plurality of slots 2111 are arranged on both sides; the slide 130 also includes a first side and a second side opposite to each other, and a clamping portion 120 is arranged on both sides. The first side of the slide 130 contacts the first side of the first adjustment bracket 30, and the second side of the slide 130 contacts the second side of the first adjustment bracket 30. When the positions of the slide 130 and the first adjustment bracket 30 are relatively fixed, the clamping portion 120 on the first side of the slide 130 is clamped into the slot 2111 on the first side of the first adjustment bracket 30, and the clamping portion 120 on the second side of the slide 130 is clamped into the slot 2111 on the second side of the first adjustment bracket 30, so as to ensure that the limit is more reliable. Of course, it can be understood that when the plurality of slots 2111 are only arranged on the first side or the second side of the first adjustment bracket 30, the clamping portion 120 is only correspondingly arranged on the first side or the second side of the slide 130.

[0071] In one embodiment, reference Figure 4 The body 131 of the slide 130 is rectangular, and the clamping portion 120 protrudes from the body 131 along the width direction of the body 131. Along the length direction of the body 131, two clamping portions 120 are arranged on each long side of the body 131, and the clamping slot includes two groups of first slot positions that are arranged oppositely, and the first slot positions are arranged corresponding to the long sides, and each group of first slot positions includes a plurality of slot positions 2111. In the assembled state, the two clamping portions 120 arranged on each long side of the body 131 are clamped into two slot positions 2111 arranged at intervals, for example, the two clamping portions 120 on one of the long sides are clamped into the slot position 2111 located at the first position and the slot position 2111 located at the third position, respectively.

[0072] In this embodiment, Figure 4As shown, a plurality of slots 2111 are provided on the first side and the second side of the first mounting area 37. For example, five slots 2111 for accommodating the clamping portion 120 are provided on the first side and the second side of the first mounting area 37. Correspondingly, two clamping portions 120 are provided on the first side and the second side of the slide 130. The two clamping portions 120 can be respectively clamped into the slots 2111 located at the second position and the fourth position. In this way, by matching the plurality of clamping portions 120 and the plurality of slots 2111, the connection reliability between the slide 130 and the first adjustment bracket 30 can be improved. It can be understood that when the two clamping portions 120 move to the slots 2111 located at the first position and the third position, the slide 130 and the conductive seal 40 (described in detail later) still maintain contact.

[0073] In other possible embodiments, the number of snap-in portions 120 provided on the two long sides of the main body 131 of the slide 130 may be different. For example, two snap-in portions 130 are provided on one of the long sides, and in the assembled state, the two snap-in portions 120 are respectively snapped into the slots 2111 at the second position and the fourth position, and only one snap-in portion 120 may be provided on the other long side, and in the assembled state, the snap-in portion 120 is snapped into the slot 2111 at the third position.

[0074] In an exemplary embodiment, reference Figures 2 to 5 , the first adjustment bracket 30 includes an insulating body and a conductive layer 34 arranged on the insulating body. The conductive layer 34 can be formed on the first adjustment bracket 30 by injection molding. Of course, a slot adapted to the conductive layer 34 can also be opened on the first adjustment bracket 30, and the conductive layer 34 can be arranged in the slot and located in the inner surface of the slot. Among them, the insulating body is used to achieve insulation between the pole 20 and the slide 130 and the battery housing 10, and prevent the pole 20 and the slide 130 from short-circuiting with the battery housing 10 due to contact. The conductive layer 34 includes a first conductive area, and the first conductive area extends to the slot 2111. The slide 130 is made of a conductive material. For example, the material of the slide 130 can be a metal material with good conductivity such as silver, copper, gold, etc., and of course, it can also be other materials with good conductivity, such as conductive ceramics. In the assembled state, the slide 130 is electrically connected to the first conductive area and the pole 20 respectively. The pole 20 can be fixedly connected to the sliding piece 130 by riveting, screwing or laser welding.

[0075] In this embodiment, combined with Figure 3 and Figure 4The insulating body of the first adjustment bracket 30 constitutes the first installation area 37, the slide 130 is installed in the first installation area 37, the slot 2111 is set in the first installation area 37, and the first conductive area extends to the slot 2111, so that the slide 130 can always maintain electrical connection with the first conductive area when moving in the first installation area 37.

[0076] Exemplarily, the first conductive region may cover the entire surface of the slot 2111. Of course, it may 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 slide 130 moves. It is sufficient as long as the slide 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 pole adjustment assembly also includes a conductive seal 40, which can be, for example, a screw, a pin, a stud, etc. that can conduct electricity, and the second adjustment unit 200 also includes a first conductive connector 220. Among them, the first conductive connector 220 is used to electrically connect the conductive seal 40 with the battery cell tab, and the first conductive connector 220 can be, for example, a battery cell tab welding metal plate. The conductive seal 40 is used to fix the first adjustment bracket 30 and the first conductive connector 220 to the battery housing 10. The first adjustment bracket 30 is provided with a mounting hole (not shown in the figure), and 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 the second conductive region is electrically connected to the conductive seal 40, so that the conductive layer 34 is conductively connected to the first conductive connector 220. Among them, the second conductive region can cover the entire inner surface of the mounting hole, and of course, the second conductive region can also cover part 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, Figure 3As shown, the insulating body of the first adjustment bracket 30 includes a first body 31, a second body 32, and a connecting portion (not shown in the figure) connecting the first body 31 and the second body 32, wherein the first body 31 is arranged on the first surface 12 of the middle frame 11, and the second body 32 is arranged on the second surface 13 of the middle frame 11, and the connecting portion passes through the battery shell hole to connect the first body 31 and the second body 32. Through holes are respectively provided on the first body 31 and the second body 32, and a connecting hole (not shown in the figure) is provided on the connecting portion to pass through the above two through holes.
