[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0025] The technical solution of the present application is described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 7 As shown, the door lock of the embodiment of the utility model includes a rear panel 1 and a lithium battery 3. The rear panel 1 is suitable for being installed on the inner side of the door. The rear panel 1 has a lithium battery slot 101, and a male connector 2 is arranged in the lithium battery slot 101. The lithium battery 3 is arranged in the lithium battery slot 101. The lithium battery 3 includes a battery body 301 and a female connector 302. The battery body 301 has a bottom surface 3011 and a first side surface 3012 connected to the bottom surface 3011. A first mounting groove is arranged at the connection between the bottom surface 3011 and the first side surface 3012. The female connector 302 is arranged in the first mounting groove and is electrically connected to the battery body 301. The female connector 302 is electrically connected to the male connector 2.

[0027] When assembling the lithium battery 3 of the present embodiment, the female connector 302 can be mounted in the first mounting groove of the battery body 301, or the female connector 302 and the battery body 301 can be integrated, for example, the female connector 302 and the battery body 301 are connected by welding.

[0028] Since the first mounting groove is provided on the battery body 301, when the female connector 302 is installed in the first mounting groove, the female connector 302 is entirely located in the first mounting groove, thereby preventing the female connector 302 from protruding from the end surface of the battery body 301. When the lithium battery 3 is installed in the lithium battery slot 101, interference between the female connector 302 and the slot wall of the lithium battery slot 101 can be avoided, making the lithium battery 3 of the embodiment of the utility model easy to assemble, and further making the door lock of the embodiment of the utility model easy to assemble.

[0029] Alternatively, if Figure 5 As shown, the female connector 302 has a slot 3024, a portion of the slot 3024 notch is provided on the first end surface 3021, and another portion of the slot 3024 notch is provided on the second end surface 3022, and a conductive sheet 3025 electrically connected to the battery body 301 is provided on the side wall of the slot 3024. The male connector 2 includes a conductive member 201, and the conductive member 201 has a plug-in portion 2011, which is inserted into the slot 3024 and electrically connected to the conductive sheet 3025.

[0030] Since the conductive sheet 3025 is arranged on the side wall of the slot 3024, after the plug-in portion 2011 of the conductive member 201 is inserted into the slot 3024, the contact area between the conductive member 201 and the conductive sheet 3025 is large. When a large vibration is generated when the door is closed, even if there is an assembly gap between the lithium battery 3 and the lithium battery slot 101, it is not enough to cause the plug-in portion 2011 of the conductive member 201 to be pulled out of the slot 3024 and separated from the conductive sheet 3025, which greatly improves the conductivity reliability between the male head 2 and the female head 302, so that the door lock of the embodiment of the utility model has higher working reliability.

[0031] Optionally, there are multiple slots 3024, which are arranged at intervals along the width direction of the battery body 301, wherein the conductive sheets 3025 in some of the slots 3024 are electrically connected to the positive electrode of the battery body 301, and the conductive sheets 3025 in other slots 3024 are electrically connected to the negative electrode of the battery body 301. Therefore, the door lock of the embodiment of the utility model only needs to be provided with one male connector 2 and one female connector 302 to achieve the electrical connection between the positive and negative electrodes of the battery body 301 and the electrical components on the door lock at the same time, which can reduce the number of male connectors 2 and female connectors 302, and is conducive to reducing costs.

[0032] In some embodiments, the female connector 302 has a first end face 3021 and a second end face 3022 connected to the first end face 3021 , the first end face 3021 is parallel to the bottom face 3011 of the battery body 301 , and the second end face 3022 is parallel to the first side face 3012 of the battery body 301 .

[0033] For example, Figure 5As shown, when assembling the female connector 302, since the first end face 3021 is parallel to the bottom face 3011 of the battery body 301, and the second end face 3022 is parallel to the first side face 3012 of the battery body 301, the tooling for installing the female connector 302 can be installed based on the bottom face 3011 of the battery body 301 and the first side face 3012 of the battery body 301, so that the female connector 302 is easy to install. In addition, when the female connector 302 is installed in the first installation groove, visually, the female connector 302 and the battery body 301 are integrated, making the lithium battery 3 more beautiful as a whole, which is conducive to improving the user experience.

[0034] In some embodiments, the distance between the first end surface 3021 and the bottom surface 3011 of the battery body 301 is less than or equal to 0.1 mm. When the distance between the first end surface 3021 and the bottom surface 3011 of the battery body 301 is set too large, the plug-in portion 2011 on the conductive member 201 of the male connector 2 needs to be set longer to be matched with the upper slot 3024 of the female connector 302, resulting in an increase in the cost of the male connector 2.

[0035] In some embodiments, the distance between the second end surface 3022 and the first side surface 3012 of the battery body 301 is less than or equal to 0.1 mm. The plug portion 2011 on the conductive member 201 of the male connector 2 needs to be longer in size to be mated with the upper slot 3024 of the female connector 302, which increases the cost of the male connector 2.

[0036] In some embodiments, the connection between the first end face 3021 and the second end face 3022 has a rounded corner 3023. It is understandable that for the sake of aesthetics, the edge of the battery body 301 is usually provided with a rounded corner, for example, a rounded corner is provided between the bottom surface 3011 and the first side surface 3012 of the battery body 301. By providing the rounded corner 3023 at the connection between the first end face 3021 and the second end face 3022 of the female connector 302, it can be adapted to the rounded corner between the bottom surface 3011 and the first side surface 3012 of the battery body 301, so as to maintain the consistency of the appearance of the lithium battery 3 and improve the user experience.

[0037] In some embodiments, Figure 3 and Figure 4As shown, the lithium battery slot 101 has a first slot side wall 1011 and a second slot side wall 1012 that are arranged opposite to each other, the first slot side wall 1011 has a protrusion 102, and the first side surface 3012 has a positioning groove 3013, and at least a portion of the protrusion 102 is placed in the positioning groove 3013. When installing the lithium battery 3, firstly, the protrusion 102 on the first slot side wall 1011 is placed in the positioning groove 3013 on the lithium battery 3, which can realize rapid pre-positioning of the lithium battery 3, so as to quickly connect with the male connector 2 and the female connector 302, which is conducive to improving the assembly efficiency of the lithium battery 3.

[0038] Optionally, there are multiple protrusions 102 , which are spaced apart on the first groove sidewall 1011 , and there are multiple positioning grooves 3013 , which correspond one-to-one to the multiple protrusions 102 and are positioned and matched.

[0039] Specifically, Figure 3 and Figure 4 As shown, there are two protrusions 102 and two positioning grooves 3013, and the two protrusions 102 are arranged at intervals in the width direction of the lithium battery 3. By providing multiple protrusions 102 and multiple positioning grooves 3013 for positioning and matching, it is beneficial to improve the positioning accuracy of the lithium battery 3 during installation, and further help to improve the assembly efficiency.

[0040] Optionally, a second mounting groove is provided on the first groove side wall 1011 , the male connector 2 is disposed in the second mounting groove, and the plug-in portion 2011 of the conductive member 201 protrudes from the first groove side wall 1011 .

[0041] In some embodiments, the battery body 301 further includes a second side surface 3014 disposed opposite to the first side surface 3012 in the length direction of the battery body 301, and an elastic arm 3015 is disposed on the second side surface 3014. The elastic arm 3015 extends along the thickness direction of the battery body 301 and the elastic arm 3015 can be elastically deformed in the length direction of the battery body 301. In the length direction of the battery body 301, the elastic arm 3015 has a clamping portion 30151 on a side away from the second side surface 3014, and a matching portion 103 is disposed on the second groove side wall 1012, and the matching portion 103 is clamped and matched with the clamping portion 30151.

[0042] Specifically, Figure 3 , Figure 4 and Figure 7As shown, the snap-on portion 30151 and the matching portion 30151 are both protrusions extending along the length direction of the battery body 301. When installing the lithium battery 3, first place one end of the lithium battery 3 in the lithium battery slot 101 and position the positioning slot 3013 on the lithium battery 3 with the protrusion 102 on the first slot side wall 1011. Then, move the elastic arm 3015 in the direction away from the second slot side wall 1012 along the length direction of the battery body 301, and elastically deform the elastic arm 3015. Finally, place the other end of the lithium battery 3 in the lithium battery slot 101 and restore the elastic arm 3015 to its elastic deformation. After the elastic arm 3015 restores its elastic deformation, the snap-on portion 30151 and the matching portion 103 are snapped in the thickness direction of the lithium battery 3, thereby completing the installation of the lithium battery 3.

[0043] When disassembling and assembling the lithium battery 3, the elastic arm 3015 is pushed along the length direction of the battery body 301 in the direction away from the second groove side wall 1012, so that the elastic arm 3015 undergoes elastic deformation, so that the clamping part 30151 is separated from the matching part 103, and then the lithium battery 3 is taken out from the lithium battery groove 101, thereby completing the disassembly of the lithium battery 3, making the lithium battery 3 easy to disassemble and assemble.

[0044] In some embodiments, the battery body 301 also has a top surface 3016 arranged opposite to the bottom surface 3011 in the thickness direction of the battery body 301. In the thickness direction of the battery body 301, one end of the elastic arm 3015 adjacent to the bottom surface 3011 is connected to the second side surface 3014, and one end of the elastic arm 3015 adjacent to the top surface 3016 has a pressing portion 30152. The pressing portion 30152 is arranged flush with or lower than the top surface 3016, and the pressing portion 30152 is used to press the elastic arm 3015 in the length direction of the battery body 301.

[0045] like Figure 4 and Figure 7 As shown, the pressing portion 30152 is flush with the top surface 3016 of the lithium battery 3 or is located below the top surface 3016 of the lithium battery 3, so that the depth of the lithium battery container 101 can be set relatively small to avoid interference between the pressing portion 30152 and the lithium battery container cover.

[0046] In some embodiments, in the length direction of the battery body 301, the side of the pressing portion 30152 away from the second side surface 3014 has a groove 30153, and the rear panel 1 has an avoidance groove 104 at a position corresponding to the pressing portion 30152. When controlling the elastic deformation of the elastic arm 3015, the hand can be placed in the avoidance groove 104, and the pressing portion 30152 can be pressed through the groove 30153 on the pressing portion 30152 along the length direction of the lithium battery 3 to achieve elastic deformation of the elastic arm 3015, so that the clamping portion 30151 and the matching portion 103 can be clamped and matched, thereby making the operation convenient.
