[0050] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0051] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be noted that the terms "upper", "lower" and similar expressions used herein are only for the purpose of illustration and are not intended to be limiting.

[0052] In this document, ordinal numbers such as “first” and “second” cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order.

[0053] In order to thoroughly understand the implementation of the utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the utility model is described in detail below, but in addition to these detailed descriptions, the utility model can also have other implementations.

[0054] The utility model provides a handle device for a battery shell. The handle device can be used for the battery shell. The handle 140 of the handle device can move between a lifting position and a storage position, and the handle device can automatically return to the storage position under the action of a magnetic component 160.

[0055] Please refer to Figures 2 to 6 The handle device includes a handle cover assembly 110. The handle cover assembly 110 can be a part of the battery housing or can be connected to the battery housing.

[0056] The handle device further includes a handle 140. The handle 140 is movably connected to the handle cover assembly 110 along the extension direction D1. In this way, the handle 140 is movable between the lifting position and the storage position. The handle 140 located at the storage position is at least partially located in the handle mounting groove 131. When the user holds the handle 140 to apply a pulling force to the handle 140, the handle 140 moves away from the handle cover assembly 110 along the extension direction D1, thereby moving from the storage position to the lifting position. When the handle 140 moves to the lifting position, the action of the handle 140 on the handle cover assembly 110 can lift the battery.

[0057] It should be noted that when the handle device is used for a battery, the telescopic direction D1 is parallel to the vertical direction. The limiting direction D2 and the extension direction D3 described below are both parallel to the horizontal direction. The limiting direction D2 and the extension direction D3 are perpendicular. In this way, the telescopic direction D1 and the limiting direction D2 intersect. For example, they are perpendicular. At this time, the handle 140 that has left the storage position automatically returns to the storage position under the action of gravity and the magnetic member 160 described below.

[0058] It can be understood that in an embodiment not shown, the telescopic direction D1 may also be parallel to the horizontal direction.

[0059] The handle 140 and the handle cover assembly 110 are both metal parts. Figure 2 and Figure 3 As shown, the handle device further includes a magnetic member 160. The magnetic member 160 may be a magnet. The magnetic member 160 is connected to the handle 140 and the handle cover assembly 110 to generate a magnetic force. The magnetic force can move the handle 140 toward the storage position.

[0060] Optionally, the magnetic member 160 is connected to one of the handle 140 and the handle cover assembly 110. The magnetic member 160 generates a magnetic force on the other. The magnetic force may be a magnetic attraction force having a magnetic attraction effect. The magnetic attraction force may magnetically attract the other, thereby enabling the handle 140 to move toward the storage position. Specifically, the magnetic member 160 is connected to the handle 140. The magnetic member 160 can generate a magnetic attraction force on the handle cover assembly 110. Therefore, the handle device only needs to include one magnet, and the structure of the handle device is simple.

[0061] It can be understood that in an embodiment not shown, the magnetic member can also be connected to the handle cover assembly. In this case, the magnetic member generates a magnetic attraction force on the handle.

[0062] It is understood that in an embodiment not shown, the magnetic member may include a first magnetic member and a second magnetic member. The first magnetic member is connected to the handle. The second magnetic member is connected to the handle cover assembly. The same magnetic poles of the first magnetic member and the second magnetic member are opposite. In this way, the first magnetic member and the second magnetic member generate a magnetic repulsion force (an example of magnetic force). The magnetic repulsion force causes the handle that leaves the storage position to automatically return to the storage position.

[0063] Please refer to Figure 3 When the handle 140 leaves the storage position, if the user releases the force exerted on the handle 140, the handle 140 automatically moves toward the storage position under the magnetic force of the magnetic member 160. At this time, the handle 140 is located in the handle cover assembly 110, and the structural size of the handle device is small. The battery using the handle device can use a larger battery unit, thereby increasing the capacity of the battery using the handle device.

[0064] Optionally, refer to Figures 2 to 4 ,as well as Figure 6The handle 140 includes a handle body 141 and a mounting portion 142. The handle body 141 is a long strip structure. The length direction of the handle body 141 is parallel to the extension direction D3. The end of the handle body 141 along the extension direction D3 is provided with a mounting portion 142. The mounting portion 142 extends and protrudes toward the handle cover assembly 110 along the telescopic direction D1. The mounting portion 142 has a limiting hole 143. The axis of the limiting hole 143 is parallel to the telescopic direction D1. The opening of the limiting hole 143 faces the handle cover assembly 110. The magnetic member 160 is located in the limiting hole 143. The magnetic member 160 can be fixedly connected to the inner surface of the limiting hole 143 by colloid. In this way, the magnetic member 160 can be prevented from detaching from the handle 140. The handle 140 can also protect the magnetic member 160.

[0065] In this way, the magnetic member 160 is disposed at the end of the handle 140, and the structure of the handle device is simple.

[0066] like Figures 2 to 7 As shown, the handle cover assembly 110 has a first protrusion 122. The handle device also includes a transition piece 170. The transition piece 170 is a nylon resin piece. The transition piece 170 has strong wear resistance. The transition piece 170 has self-lubricating properties. The transition piece 170 has good heat resistance and anti-aging properties. The transition piece 170 is sleeved on the first protrusion 122 and is located in the limiting hole 143. The first hole section 172 and the inner diameter size of the transition piece 170 can be slightly larger than the outer diameter size of the first protrusion 122. In this way, the transition piece 170 and the first protrusion 122 can be transitionally matched. The outer diameter size of the outer peripheral surface of the transition piece 170 can be slightly smaller than the inner diameter size of the limiting hole 143. In this way, the transition piece 170 and the handle 140 can be transitionally matched. In this way, the first protrusion 122 , the transition piece 170 cooperate with the limiting hole 143 to limit the movement of the handle 140 relative to the handle cover assembly 110 along the limiting direction D2 and the extending direction D3 .

[0067] like Figure 3 and 7 As shown, the transition piece 170 includes an internal through hole and a partition wall 171 located in the internal through hole. In this way, the partition wall 171 divides the internal through hole into a first hole section 172 and a second hole section 173. Along the telescopic direction D1, the first hole section 172 and the second hole section 173 are arranged at intervals. The first hole section 172 is sleeved on the first protrusion 122. The opening of the second hole section 173 faces the magnetic component 160 to avoid the magnetic component 160. As a result, the transition piece 170 has a small weight and a simple structure.

[0068] Please refer to Figure 2 and Figure 3The handle device further includes a fastener 150. The fastener 150 may be a carbon steel member, such as a screw. The fastener 150 is disposed through the partition wall 171 of the transition member 170 and is threadedly connected to the first protrusion 122. In the horizontal direction, the fastener 150 is located directly below the magnetic member 160, so that the magnetic member 160 can generate a magnetic force on the fastener 150, and then generate a magnetic force on the handle cover assembly 110 through the fastener 150.

[0069] It is understood that in an embodiment not shown, the handle cover assembly may be a carbon steel member. In this case, the magnetic member directly generates magnetic force on the handle cover assembly, and a fastener connecting the first protrusion may not be provided.

[0070] Optionally, refer to Figure 2 and Figure 3 ,as well as Figure 5 and Figure 6 The handle cover assembly 110 has a handle installation groove 131 . The edge of the side wall of the handle installation groove 131 away from the bottom wall thereof extends along the limiting direction D2 and protrudes into the interior of the handle installation groove 131 to form a first limiting portion 132 .

[0071] The edge of the mounting portion 142 of the handle 140 away from the handle body 141 extends and protrudes along the limiting direction D2. To form a second limiting portion 144. The mounting portion 142 of the handle 140 is located in the handle mounting groove 131. The second limiting portion 144 is located on the right side of the first limiting portion 132 along the telescopic direction D1 close to the bottom wall of the handle mounting groove 131. In this way, when the handle 140 moves to the lifting position, the first limiting portion 132 can block the second limiting portion 144 to prevent the handle 140 from moving further away from the storage position. Therefore, by setting the first limiting portion 132 and the second limiting portion 144, the movement of the handle 140 along the telescopic direction D1 is limited between the storage position and the lifting position, and the structure of the handle device is simple.

[0072] In the present embodiment, the handle 140 is movable between a storage position and a lifting position, so that when the handle 140 is not subjected to external force, the handle 140 is at least partially stored in the handle cover assembly 110, the structural size of the handle device is small, and the battery using the handle device can use a larger volume of battery cells, and the battery power is large; when the handle 140 is subjected to a pulling force along the extension direction D1, it can be moved to the lifting position, and then the battery is lifted; the provision of the magnetic component 160 enables the handle 140 that leaves the storage position to automatically return to the storage position without being subjected to external force.

[0073] Furthermore, if Figures 2 to 5As shown, the handle cover assembly 110 includes a handle cover 120 and a fixing member 130. The fixing member is a substantially rectangular parallelepiped structure. The handle 140, the handle cover 120 and the fixing member 130 may be aluminum alloy parts. The handle cover 120 can reach the IP67 protection level and has good waterproof performance. The handle 140 and the fixing member 130 have high strength and are easy to process. In this way, the handle 140, the handle cover 120 and the fixing member 130 are light in weight, and the heat dissipation performance of the handle 140, the handle cover 120 and the fixing member 130 is strong.

[0074] The handle cover 120 may constitute part of the battery housing. The fixing member 130 is detachably connected to the handle cover 120. The fixing member 130 has a handle mounting groove 131 and a first stopper 132. In this way, the handle 140 is connected to the handle cover 120 through the fixing member 130, which facilitates the installation of the handle 140.

[0075] like Figure 2 and Figure 3 As shown, the handle cover 120 has a cover mounting groove 121. The cover mounting groove 121 is a substantially rectangular parallelepiped structure. The fixing member 130 is located in the cover mounting groove 121. As a result, the volume of the handle device is small, and the capacity of the battery using the handle device can be increased.

[0076] Please continue to refer to Figure 2 and Figure 3 The cover installation groove 121 has a second protrusion 123 extending and protruding along the telescopic direction D1. The bottom surface of the installation groove extends and protrudes along the telescopic direction D1 to form the aforementioned first protrusion 122. The second protrusion 123 is spaced apart from the first protrusion 122.

[0077] The fixing member 130 has a mounting hole 133. The mounting hole 133 is sleeved on the second protrusion 123. At this time, the fixing member 130 can be detachably connected to the second protrusion 123 by the fastener 150. In this way, it is convenient to position the fixing member 130. In addition, the connection strength between the fixing member 130 and the handle cover 120 can be increased.

[0078] Alternatively, if Figure 3 and Figure 5 As shown, the second protrusion 123 may include a second protrusion A124 and a second protrusion B125. Along the telescopic direction D1, the second protrusion A124, the first protrusion 122 and the second protrusion B125 are arranged in sequence. The mounting hole 133 includes a first mounting hole 134 and a second mounting hole 135. The second protrusion A124 extends into the first mounting hole 134. The second protrusion B125 extends into the second mounting hole 135. Thus, the positioning of the fixing member 130 can be more convenient. In addition, the connection between the fixing member 130 and the handle cover 120 is more secure.

[0079] like Figure 2 and Figure 3As shown, the surface of the handle cover 120 facing the handle body 141 is recessed along the extension direction D1 to form a handle storage groove 126. The handle storage groove 126 may include an arcuate surface. The handle storage groove 126 is connected to the cover mounting groove 121. Along the extension direction D3, the handle storage groove 126 is located between the two mounting portions 142 of the handle 140. In this way, along the extension direction D3, the handle storage groove 126 is located at the handle body 141. The handle 140 located at the storage position is at least partially located in the handle storage groove 126. For example, the handle 140 located at the storage position is located in the handle storage groove. At this time, the handle 140 does not protrude from the upper surface of the handle cover 120 (for example, the upper surface of the handle 140 is flush with the upper surface of the handle cover 120.). In this way, the user's hand can be inserted into the handle storage groove 126 to be able to hold the handle body 141. Thus, the handle 140 can be operated conveniently.

[0080] It is understood that in an embodiment not shown, part of the handle in the storage position is located in the handle storage slot. At this time, the handle protrudes from the upper surface of the handle cover (for example, the upper surface of the handle is located above the upper surface of the handle cover).

[0081] Optionally, both side surfaces of the handle 140 along the extension direction D1 are smooth surfaces. The handle 140 can bring a better user experience.

[0082] Furthermore, a colloid layer is provided on the surface of the handle body 141 close to the handle cover 120 to increase the comfort of holding the handle body 141 .

[0083] Please refer to Figure 2 and Figure 3 When installing the handle device, the transition piece 170 can be first connected to the first protrusion 122 by a fastener; then the mounting portion 142 of the handle 140 is set in the handle mounting groove 131 of the fixing piece 130; then the fixing piece 130 and the handle 140 are set together in the cover mounting groove 121, and the limiting hole 143 is sleeved on the transition piece 170; then the fixing piece 130 and the second protrusion 123 are connected by the fastener 150. In this way, the installation of the handle device is completed.

[0084] The utility model also provides a battery, which includes the aforementioned handle device.

[0085] In this embodiment, the battery includes the aforementioned handle device, and the handle 140 is movable between a storage position and a lifting position. In this way, when the handle 140 is not subjected to external force, the handle 140 is at least partially stored in the handle cover assembly 110.
