DETAILED DESCRIPTION

[0056] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "multiple" means two or more, and at least one means one, two or more, unless otherwise clearly and specifically defined. In the description of this application, "vertical" means completely vertical at 90° or almost completely vertical, for example, an angle within the range of 80° to 100° is considered vertical. Similarly, "parallel" means completely parallel or almost completely parallel, for example, an angle within 10° of completely parallel is considered parallel.

[0058] It should also be noted that in the drawings of the present application, the arrow marked X indicates the first direction X, the arrow marked Y indicates the second direction Y, and the arrow marked Z indicates the third direction Z. In the embodiment of the present application, the first direction X is the direction of the battery 11 toward the end plate 4, the second direction Y is the direction of the battery 11 toward the cover plate 2, and the third direction Z is the direction of the battery 11 toward the side plate 8. The first direction X, the second direction Y and the third direction Z are introduced to facilitate the description of the structural position relationship of the various components of the battery pack, thereby facilitating the understanding of its structure.

[0059] The applicant noted that a battery pack is usually composed of multiple batteries connected in series and in parallel, which output current to the outside through the output pole piece. Since the output pole piece is a live conductor, it needs to be insulated to avoid short circuit or accidental touch. At present, a combination of a separate output pole base and a protective cover is often used to protect the output pole piece, which can achieve the fixation and insulation protection of the output pole piece. However, the disadvantage of this arrangement is that there are many parts and components, the cost is high, and once maintenance is carried out, it is very easy for the protective cover to be missing, lost, or damaged.

[0060] In view of this, an embodiment of the present application provides a battery pack to solve the above-mentioned problems.

[0061] Please refer to Figure 1-Figure 12, the embodiment of the present application provides a battery pack, the battery pack has a first direction X and a second direction Y intersecting each other, and the battery pack includes a battery pack 1, a cover plate 2, an output pole piece 5 and a first protective member 6. The battery pack 1 includes a plurality of batteries 11 arranged along the first direction X, and the battery 11 includes an electrode terminal 12. The cover plate 2 is arranged opposite to the electrode terminal 12 along the second direction Y, at least one end plate 4 is connected to the battery pack 1 along the first direction X, one end of the output pole piece 5 is connected to the electrode terminal 12, and the other end of the output pole piece 5 is arranged on the end plate 4 along the second direction Y, and the first protective member 6 is arranged on the side of the cover plate 2 away from the battery pack 1; the first protective member 6 can slide along the first direction X after being subjected to force, so that at least part of the output pole piece 5 is located between the first protective member 6 and the end plate 4 along the second direction Y.

[0062] In the embodiment of the present application, by slidably arranging the first protective member 6 on the side of the cover plate 2 away from the electrode terminal 12, it is convenient to slide the first protective member 6 according to actual needs to achieve shielding or exposing the output pole piece 5, thereby achieving protection of the output pole piece 5 and connecting the output pole piece 5 to the external circuit; at the same time, the first protective member 6 of the present application is slidably integrated with the cover plate 2, and the overall structure is simple, which facilitates the opening and closing of the first protective member 6, and effectively avoids the first protective member 6 from being damaged or lost due to disassembly or assembly during maintenance.

[0063] Specifically, in an embodiment of the present application, the battery pack may include a battery pack 1 composed of a plurality of batteries 11 arranged along a first direction X, a cover plate 2 arranged on the top of the battery pack 1 along a second direction Y, a bottom plate 3 arranged on the bottom of the battery pack 1 along the second direction Y, and side plates 8 respectively arranged on both sides of the battery pack 1 along a third direction Z. Among them. The side plates 8 are respectively connected to the end plates 4 on both sides of the battery pack 1 along the first direction X, and the side plates 8 are respectively connected to the cover plate 2 and the bottom plate 3 along the second direction Y. In this way, the battery pack 1 is packaged by using the end plates 4, the side plates 8, the cover plate 2 and the bottom plate 3, so that the battery pack 1 has a compact structure and the volume of the battery pack is reduced. The electrode terminal 12 may specifically be a pole of the battery 11, which is used for charging and discharging the battery 11. The cover plate 2 is arranged opposite to the electrode terminal 12. Specifically, the cover plate 2 can be arranged on the side of the battery 11 where the electrode terminal 12 is arranged. After the multiple electrode terminals 12 are connected in series or in parallel, they need to be connected to the output pole piece 5 to output the current of the battery pack 1 to the outside. The output pole piece 5 can extend outward from the gap between the cover plate 2 and the end plate 4 to facilitate connection with the external circuit. The present application arranges the first protective member 6 on the side of the cover plate 2 away from the electrode terminal 12. Further, it can be arranged on the side of the cover plate 2 away from the output pole piece 5, and the projections of the first protective member 6 and the output pole piece 5 along the second direction Y on the plane where the cover plate 2 is located at least partially overlap. At this time, the sliding distance of the first protective member 6 along the first direction X can be reduced, so that the cost of setting the slide rail 21 can be reduced. In the embodiment of the present application, the first protective member 6 can slide along the first direction X so that the first protective member 6 and the output pole piece 5 are at least partially opposite in the second direction Y. At this time, the first protective member 6 can cover the output pole piece 5 in the second direction Y. Further, when the first protective member 6 completely covers the portion of the output pole piece 5 extending outside the cover plate 2 along the second direction Y, insulation protection of the exposed portion of the output pole piece 5 is achieved. Since the first protective member 6 is slidably connected to the cover plate 2, when the battery pack needs to be repaired and the cover plate 2 needs to be disassembled, the first protective member 6 is removed together with the cover plate 2 and always remains connected to the cover plate 2, thereby avoiding the loss of the first protective member 6. When the cover plate 2 needs to be installed after the repair is completed, the first protective member 6 returns to the vicinity of the output pole piece 5 after the cover plate 2 is installed, and further realizes its function of insulating and protecting the output pole piece 5.

[0064] In addition, the first protective member 6 of the embodiment of the present application is slidably connected to the cover plate 2, and the first protective member 6 can be slid at any time as needed to block or expose the output pole piece 5, which makes the operation simpler and is not easy to damage the first protective member 6, thereby effectively extending the service life of the first protective member 6.

[0065] It should also be noted that the first protective member 6 of the embodiment of the present application is an insulating member, so that the charged output pole piece 5 can be insulated and protected.

[0066] like Figure 8 As shown, in some embodiments, a slide rail 21 extending along the first direction X is provided on the side of the cover plate 2 facing away from the battery pack 1 , and the first protective member 6 is provided with a slide groove 61 , and the slide rail 21 is embedded in the slide groove 61 .

[0067] In the embodiment of the present application, by setting the slide rail 21 and the slide groove 61, on the one hand, the connection between the first protective member 6 and the cover plate 2 is achieved, and at the same time, the structure of the slide rail 21 and the slide groove 61 is easy to achieve and has a simple structure, which is more convenient for the molding and production of the cover plate 2 and the first protective member 6.

[0068] In the embodiment of the present application, the slide rail 21 is used to provide a direction guide for the first protection member 6 to slide along the first direction X, so as to achieve directional sliding of the first protection member 6. In addition, the first protection member 6 is provided with a slide groove 61, and through the mutual cooperation between the slide groove 61 and the slide rail 21, the first protection member 6 can slide quickly, making it easier to achieve the operation of sliding the first protection member 6 along the first direction X.

[0069] It should be noted that the slide rail 21 of the present application can be a single slide rail of T-shaped, I-shaped or other similar structure, or a combination of C-shaped or L-shaped double rails arranged back to back, or other rails that can achieve a guiding function.

[0070] In some embodiments, the battery pack further includes a third direction Z intersecting with both the first direction X and the second direction Y. The first protective member 6 includes a top wall 62 and two stoppers 63 arranged oppositely along the third direction Z. The top wall 62 is arranged oppositely to the cover plate 2. The stopper 63 includes a side wall 631 and a first stopper 632. The side wall 631 is connected to the top wall 62 to form a slide groove 61. The first stopper 632 is arranged in the slide groove 61 and connected to the side wall 631. The first stopper 632 is spaced apart from the top wall 62 to form a stopper groove 633 with the side wall 631. The stopper groove 633 is connected to the slide groove 61. The slide rail 21 includes a guide portion 211 arranged oppositely along the third direction Z. The guide portion 211 extends along the first direction X. The guide portion 211 includes a first body 2111 and a second limiting member 2112. The first body 2111 is arranged in the slide groove 61 and connected to the cover plate 2. The second limiting member 2112 is connected to an end of the first body 2111 away from the cover plate 2 and is arranged opposite to the cover plate 2. The second limiting member 2112 is slidably connected in the limiting groove 633. In this way, the sliding cooperation between the second limiting member 2112 and the limiting groove 633 can realize the sliding of the first protective member 6 relative to the slide rail 21.

[0071] In the embodiment of the present application, the first protection member 6 is realized to slide along the first direction X on the side of the cover plate 2 away from the battery pack 1 by the cooperation between the guide portion 211 and the limiting portion 63. Further, the present application uses the first limiting member 632, the top wall 62 and the side wall 631 to enclose a limiting groove 633, which can be a C-shaped limiting groove 633. At the same time, the first body 2111 and the second limiting member 2112 are connected to form an L-shaped guide portion 211, wherein the second limiting member 2112 is slidably connected in the limiting groove 633. In this way, the second limiting members 2112 of the guide portions 211 on both sides cooperate with the limiting grooves 633 on both sides, so that the slide rail 21 limits the freedom of the first protection member 6 in the second direction Y and the third direction Z, so that the first protection member 6 can only slide along the first direction X, thereby avoiding the first protection member 6 from contacting and connecting with the slide rail 21 along the second direction Y and the third direction Z, thereby avoiding the loss of the first protection member 6.

[0072] It should be noted that the present application prefers to use two symmetrically arranged limiting portions 63 to limit the slide rail 21 on both sides. At this time, the slide rail 21 is limited by a limiting portion 63 on both sides along the third direction Z, respectively. This can achieve better limiting and guiding effects and make the connection between the first protective member 6 and the cover plate 2 more stable.

[0073] like Figure 5-Figure 7 As shown, in some embodiments, the limiting portion 63 also includes a third limiting member 634, the third limiting member 634 is arranged in the slide groove 61 and connected to the top wall 62, the third limiting member 634 and the first limiting member 632 are spaced apart, and the first body 2111 is arranged between the third limiting member 634 and the first limiting member 632.

[0074] In the embodiment of the present application, the third limiting member 634 can cooperate with the side wall 631 and the first limiting member 632 to form an L-shaped limiting space, and the guide portion 211 is limited along the third direction Z between the side wall 631, the first limiting member 632 and the third limiting member 634, thereby realizing the freedom of the first protective member 6 along the first direction X, and making the first protective member 6 as stable as possible when moving along the first direction X.

[0075] Specifically, the third stopper 634 and the first stopper 632 are matched and arranged on both sides of the first body 2111 along the third direction Z. At this time, if the first stopper 632 is subjected to a thrust along the third direction Z, the first bodies 2111 of the two guide parts 211 are respectively subjected to the blocking force of the first stopper 632 and / or the side wall 631 of one stopper 63, and / or the blocking force of the third stopper 634 of the other stopper 63. Specifically, the size of the gap between the second stopper 2112 and the side wall 631, between the first body 2111 and the adjacent third stopper 634, and between the first body 2111 and the adjacent first stopper 632 is determined.

[0076] Please refer to Figure 6-Figure 8 In some embodiments, the third limiting member 634 includes a buckle 6341 disposed toward the side wall 631 , the first body 2111 is provided with a buckle slot 2113 , and the buckle 6341 is detachably disposed in the buckle slot 2113 .

[0077] In the embodiment of the present application, the first protective member 6 can be limited in the first direction X by providing the card slot 2113 and the buckle 6341 to cooperate with each other.

[0078] Specifically, in the embodiment of the present application, when the first protective member 6 is slid along the first direction X so that the buckle 6341 is inserted into the slot 2113, the first protective member 6 cannot be pushed forward further along the sliding direction, thereby achieving the limitation of the first protective member 6 in the first direction X.

[0079] It should be noted that when there is only one card slot 2113, the card slot 2113 is preferably set at a position where the buckle 6341 is clamped in the card slot 2113 when the first protective member 6 completely blocks the output pole piece 5 in the second direction Y. Since the buckle 6341 is clamped in the card slot 2113, the first protective member 6 will not move when not under force, and the first protective member 6 can be fixed, so that the first protective member 6 can block and protect the output pole piece 5.

[0080] like Figure 8 As shown, in some embodiments, the slot 2113 includes a first positioning slot 21131 and a second positioning slot 21132 spaced apart along the first direction X, and the second positioning slot 21132 is arranged on the side of the first positioning slot 21131 away from the end plate 4; when the first protective member 6 completely covers the output pole piece 5 along the second direction Y, the buckle 6341 is clamped in the first positioning slot 21131; when the first protective member 6 completely slides onto the cover plate 2, the buckle 6341 is clamped in the second positioning slot 21132.

[0081] In the embodiment of the present application, the first positioning groove 21131 is set to enable the first protective member 6 to completely cover the output pole piece 5 to realize the protection function, and the first protective member 6 is limited and fixed along the first direction X. The second positioning groove 21132 is set to enable the first protective member 6 to completely slide onto the cover plate 2 to limit and fix the first protective member 6, so as to prevent the first protective member 6 from sliding freely along the first direction X. On the one hand, it plays the role of fixing the first protective member 6 to realize its protection function, and on the other hand, it prevents the first protective member 6 from sliding in the first direction X and detaching from the slide rail 21, that is, preventing the first protective member 6 from detaching from the cover plate 2, thereby preventing the first protective member 6 from being lost.

[0082] like Figure 8As shown, in some embodiments, a first slope 21133 is provided on the wall of the first positioning groove 21131 close to the second positioning groove 21132, and the first slope 21133 is inclined along the second direction Y in a direction away from the second positioning groove 21132; a second slope 21134 is provided on the groove wall of the second positioning groove 21132 close to the first positioning groove 21131, and the second slope 21134 is inclined along the second direction Y in a direction away from the first positioning groove 21131.

[0083] In the embodiment of the present application, a first inclined surface 21133 and a second inclined surface 21134 are provided, so that the first positioning groove 21131 and the second positioning groove 21132 can not only realize the clamping and positioning of the buckle 6341, but also enable the first protective member 6 to smoothly slide out of the first positioning groove 21131 and the second positioning groove 21132 under the action of external force, so that the first protective member 6 can regain freedom along the first direction X.

[0084] Specifically, when the buckle 6341 is located in the first positioning groove 21131, the first protective member 6 blocks the top of the output pole piece 5 to provide insulation protection. If the output pole piece 5 is to be exposed, the first protective member 6 needs to be pushed along the first direction X toward the position of the second positioning groove 21132. At this time, the first inclined surface 21133 cooperates with the buckle 6341, so that the buckle 6341 can slide out of the first positioning groove 21131 under the action of external force with the help of the first inclined surface 21133, and continue to slide along the first direction X until the buckle 6341 is inserted into the second positioning groove 21132. At this time, the first protective member 6 is opened and fixed on the cover 2. Similarly, when the first protective member 6 is needed to cover the output pole piece 5 for insulation protection, the first protective member 6 is pushed along the first direction X to the position of the first positioning groove 21131. At this time, the second inclined surface 21134 cooperates with the buckle 6341, so that the buckle 6341 can slide out of the second positioning groove 21132 with the help of the second inclined surface 21134 under the action of external force, and continue to slide along the first direction X until the buckle 6341 is inserted into the first positioning groove 21131, thereby achieving the shielding of the output pole piece 5 by the first protective member 6.

[0085] It should be noted that if Figure 7 As shown, the buckle 6341 has an outer surface that slides with the first inclined surface 21133 and the second inclined surface 21134 , so that the buckle 6341 can slide out of the sliding groove 61 smoothly.

[0086] like Figure 6 and Figure 7As shown, in some embodiments, the third limit member 634 includes a second body 6342 and an extension arm 6343, the second body 6342 is arranged in the slide groove 61 and connected to the top wall 62, the extension arm 6343 is connected to the side of the second body 6342 away from the end plate 4 along the first direction X and extends along the first direction X, and the buckle 6341 is connected to one end of the extension arm 6343 away from the second body 6342.

[0087] In the embodiment of the present application, the second body 6342 is used to connect with the top wall 62 to achieve the fixation of the third limiting member 634 and the matching limiting with the first limiting member 632 and the side wall 631. The extension arm 6343 is used to connect with the buckle 6341, so that the buckle 6341 is suspended in the slide groove 61, and the buckle 6341 has a certain range of motion along the third direction Z with the help of the extension arm 6343, so that the buckle 6341 is easy to be inserted into the slide groove 61 and to be removed from the slide groove 61. In one embodiment, the extension arm 6343 and the buckle 6341 are both made of elastic material, and the extension arm 6343 and the first body 2111 are interference fit, so that when the first protective member 6 is pushed and pulled along the first direction X, the buckle 6341 is easy to be automatically inserted into the slide groove 61, and the structure is simple and easy to operate.

[0088] like Figure 6 and Figure 7 As shown, in some embodiments, the limiting portion 63 further includes a reinforcing portion 635 , which is disposed on a side of the second body 6342 away from the side wall 631 and is respectively connected to the second body 6342 and the top wall 62 .

[0089] In the embodiment of the present application, by providing a reinforcing portion 635 connected to the second body 6342 and the top wall 62 , the structural strength of the third limiting member 634 and the connection strength with the top wall 62 are strengthened.

[0090] Preferably, the reinforcing portion 635 is disposed at the connection between the extension arm 6343 and the second body 6342. Specifically, since the extension arm 6343 is only connected to the second body 6342, and as the first protective member 6 is opened and closed, the extension arm 6343 continuously changes direction and resets in the third direction Z, and the reinforcing portion 635 is disposed at the connection between the extension arm 6343 and the second body 6342, the connection strength between the extension arm 6343 and the second body 6342 can be effectively strengthened, thereby extending the service life of the third limiter 634.

[0091] Please refer to Figure 3-Figure 7 In some embodiments, the first protective member 6 also includes a first plate body 64 and a second plate body 65, the first plate body 64 is connected to the top wall 62, and the first plate body 64 is arranged opposite to the cover plate 2 along the first direction X, and the second plate body 65 is connected to the side of the top wall 62 away from the cover plate 2.

[0092] In the embodiment of the present application, a first plate 64 is provided to further shield and protect the output pole piece 5 in the first direction X, thereby preventing hand touch and improving the insulation protection effect of the first protective member 6; a second plate 65 is provided to provide a push-pull position for the movement of the first protective member 6, thereby facilitating the movement of the first protective member 6 and keeping the operator's operating position away from the output pole piece 5, thereby reducing the risk of human hands touching the output pole piece 5 and improving operational safety.

[0093] Specifically, the first plate 64 is arranged opposite to the cover plate 2 along the first direction X. It can be understood that in the second direction Y, the first plate 64 is closer to the output pole piece 5. In this way, when the first protective member 6 slides to completely cover the output pole piece 5, the gap between the first plate 64 and the output pole piece 5 is smaller than the gap between the top wall 62 and the output pole piece 5. In this way, the output pole piece 5 can be better blocked and protected to prevent accidental contact with the output pole piece 5 in the first direction X. The second plate 65 is arranged on the side of the top wall 62 away from the cover plate 2. It can be understood that when the first protective member 6 slides to completely cover the output pole piece 5, the second plate 65 is located on the side of the top wall 62 away from the output pole piece 5. At this time, the second plate 65 is farther away from the output pole piece 5 relative to the top wall 62 and the limiter 63 and other structures, so as to further reduce the risk of accidental contact when sliding the first protective member 6. In addition, the first plate body 64 is arranged opposite to the cover plate 2 along the first direction X, and can also limit the first protective member 6 from the first direction X to prevent the first protective member 6 from sliding onto the cover plate 2 when opened, and further prevent the first protective member 6 from sliding along the slide rail in the direction away from the output pole piece 5.

[0094] Please refer to Figure 1-Figure 3 , Fig. 9 , Fig.10 and Fig.12 In some embodiments, a second protective member 7 is further included, and the second protective member 7 includes a main body 71 and a fixing portion 72 connected to the main body 71; a first accommodating groove 41 is provided on the side of the end plate 4 facing the output pole piece 5, and the end plate 4 has a side 42 facing the battery pack 1, the first accommodating groove 41 penetrates the side 42 along the first direction X, the fixing portion 72 is embedded in the first accommodating groove 41, and the main body 71 is connected to the output pole piece 5.

[0095] In the embodiment of the present application, the second protective member 7 is disposed between the end plate 4 and the output pole piece 5 , and the second protective member 7 cooperates with the first protective member 6 on the side of the output pole piece 5 away from the first protective member 6 to protect the output pole piece 5 .

[0096] Furthermore, the second protection member 7 is an insulating member, thereby achieving further insulation protection for the output pole piece 5 .

[0097] It should be noted that, in the present application, a first accommodating groove 41 is provided on the end plate 4, and the first accommodating groove 41 penetrates the side surface 42 along the first direction X, so that the first accommodating groove 41 has a connected opening on the two intersecting surfaces of the end plate 4, and at the same time, the groove bottom width of the first accommodating groove 41 along the second direction Y is greater than the groove opening width, and the width of the end of the fixing portion 72 away from the main body 71 is greater than the width of the end where the fixing portion 72 is connected to the main body 71, so that the fixing portion 72 can be directly embedded into the first accommodating groove 41 from the groove on the side surface 42, so as to realize the mortise and tenon connection between the fixing portion 72 and the first accommodating groove 41, so as to form the first accommodating groove 41 to limit the fixing portion 72 in the second direction Y, and at the same time, the side surface 42 faces the battery 11 and fits with the battery 11, and the battery 11 is used to limit the fixing portion 72 along the first direction X, so as to realize the stable connection between the second protective member 7 and the end plate 4. When the second protection member 7 needs to be removed, the end plate 4 only needs to be removed, and the second protection member 7 is slid along the first direction X, so that the fixing portion 72 can be removed from the first receiving groove 41 .

[0098] In some embodiments, a second accommodating groove 711 is disposed on one side of the main body 71 facing the output pole piece 5 , and along the second direction Y, at least a portion of the output pole piece 5 is disposed in the second accommodating groove 711 .

[0099] The embodiment of the present application provides a second accommodating groove 711 for accommodating at least part of the output pole piece 5 in the second direction Y, so as to achieve further insulation protection of the output pole piece 5 in the first direction X, the second direction Y and the third direction Z.

[0100] like Fig. 9 and Fig.10 As shown, in some embodiments, the second protective member 7 includes a third plate 73, which is connected to a side of the main body 71 away from the fixing portion 72, and is located outside the second accommodating groove 711 and extends along the second direction Y.

[0101] In the embodiment of the present application, by providing the third plate 73 , the protection height of the second protection member 7 for the output pole piece 5 can be increased in the second direction Y, and the distance between the second protection member 7 and the first protection member 6 can be reduced, thereby improving the insulation protection effect.

[0102] Furthermore, Figure 1-Figure 3 as well as Figure 11-Figure 12As shown, in some embodiments, the end plate 4 may further include a convex portion 43, which is spaced apart from the main body 71 along the third direction Z; the third plate body 73 may further be arranged between the output pole piece 5 and the convex portion 43. Since the end plate 4 is usually an aluminum profile, the third plate body 73 is made of an insulating material. At this time, the third plate body 73 is arranged between the convex portion 43 and the output pole piece 5, which, on the one hand, plays an anti-touch role, and on the other hand, isolates the output pole piece 5 and the convex portion 43, which can play a better insulation protection role.

[0103] Please refer to Figure 5 and Fig.10 In the embodiment of the present application, since the first protective member 6 is arranged on the side of the cover plate 2 away from the battery pack 1, and the first protective member 6 is arranged accordingly with the position of the output pole piece 5, so that the position between the output pole piece 5 and the first protective member 6 corresponds. When the output pole piece 5 is arranged in the middle of the battery pack 1, the corresponding first protective member 6 is completely located on the cover plate 2, and at this time, the side walls 631 of the two limiting parts 63 are exactly the same. When the output pole piece 5 is arranged at the edge of the battery pack 1, the corresponding first protective member 6 is also located at the edge of the cover plate 2. At this time, one limiting part 63 can be arranged on the cover plate 2, and the side wall 631 of the other limiting part 63 is suspended outside the cover plate 2. In the embodiment of the application, the first side wall 6311 can be located on the cover plate 2, and the second side wall 6312 can be suspended outside the cover plate 2. At this time, the size of the second side wall 6312 along the second direction Y can be set to be larger than the size of the first side wall 6311 along the second direction Y. At this time, when the first protective member 6 slides to completely cover the output pole piece 5, the first side wall 6311 can block the gap between the top wall 62 and the output pole piece 5 from the side opposite to the third plate body 73, further effectively preventing touch. In this way, the first side wall 6311 is used to further improve the insulation protection effect of the first protective member 6 in the third direction Z.
