[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] See also Figure 1 The embodiment of the present application provides a battery installation structure, including a battery box 10 and a middle frame 20. The battery box 10 includes a shell 1. At least one side of the shell 1 is provided with a battery pair groove 11. The middle frame 20 is provided with a mounting groove 201. The mounting groove 201 is used to accommodate the shell 1. When the shell 1 is arranged in the mounting groove 201, the battery pair groove 11 is arranged opposite to the groove wall of the mounting groove 201.

[0034] It should be noted that the battery mounting structure is a device used to accommodate and protect batteries, and is usually used in electronic products, such as smart door locks, electric vehicles or power tools; the battery mounting structure provides power for electronic products.

[0035] In one embodiment, a battery mounting structure includes a shell 1 and a middle frame 20, wherein the middle frame 20 is provided with a mounting groove 201, and the shell 1 may be provided with a battery pair groove 11 on one side or on two opposite sides, wherein the battery pair groove 11 is used to place a battery; when the shell 1 is placed in the mounting groove 201, the battery pair groove 11 is arranged relative to the groove wall of the mounting groove 201, that is, the notch of the battery pair groove 11 is covered or approximately covered by the groove wall of the mounting groove 201. Compared with the prior art, such an arrangement ensures that even if the electronic product is subjected to external force impact during use, for example, a smart door lock is hit by a door frame when closing the door, or an electric tool such as an electric drill is vibrated and impacted during use, the relatively arranged groove walls of the mounting groove 201 will limit the battery, thereby preventing the battery from falling out of the notch of the battery pair groove 11, thereby effectively preventing the battery from falling out of the battery pair groove 11. At the same time, the battery groove 11 and the groove wall of the installation groove 201 are arranged relative to each other, which can also play the role of hiding electrical components such as batteries. When the battery installation structure is opened, the groove wall of the installation groove 201 covers the battery groove 11, and the battery will not be exposed, thereby improving the aesthetics of the device.

[0036] It can be understood that the groove wall of the mounting groove 201 and the battery groove 11 are arranged relative to each other, which means that under the same projection plane, the projection area of ​​the groove wall of the mounting groove 201 can cover or approximately cover the projection area of ​​the battery groove 11 .

[0037] See again Figure 1 A first snap-fitting structure 202 is provided in the mounting groove 201 , and a second snap-fitting structure 16 is provided on the shell 1 . The first snap-fitting structure 202 is used to cooperate with the second snap-fitting structure 16 to fix the battery box 10 in the mounting groove 201 of the middle frame 20 .

[0038] In one embodiment, a second clip structure 16 can be provided on the adjacent side of the shell 1 to the battery slot 11, and a first clip structure 202 is provided at a position of the mounting slot 201 relative to the second clip structure 16. When the shell 1 is located in the mounting slot 201, the first clip structure 202 is connected to the second clip structure 16 to fix the shell 1 and prevent the shell 1 from detaching from the mounting slot 201.

[0039] In one embodiment, one of the first clamping structure 202 and the second clamping structure 16 may be a buckle, and the other may be a slot, and the fixing function is achieved through the clamping action of the buckle and the slot.

[0040] It is understandable that the first clamping structure 202 and the second clamping structure 16 may also be connected in other ways, which is not limited in the present application.

[0041] See also Figure 2 and Figure 3 For the sake of clarity, Figure 3 X represents the length direction; the battery box 10 also includes a reinforcement 2, and the battery slot 11 includes a first slot 111 and a second slot 112; the reinforcement 2 is arranged in the battery slot 11, and separates the battery slot 11 into the first slot 111 and the second slot 112, along the length direction X of the battery slot 11 or the battery, the reinforcement 2 is respectively connected to the opposite sides of the shell 1.

[0042] In one embodiment, when the battery box 10 is installed with a dry cell, in order to ensure that the positive and negative electrodes of the dry cell are in close contact with the contact points of the circuit, a battery spring is usually provided at the end of the dry cell, and the dry cell is tightened by the battery spring along its length direction X, and then the dry cell generates a pressing force on the side wall of the shell 1. Under the action of this pressing force, the side wall of the shell 1 is easy to bulge outward from the shell 1, and structural deformation occurs, resulting in the battery box 10 being unable to be installed in the middle frame 20. Therefore, the present application provides a reinforcement member 2, which is respectively connected to the opposite sides of the shell 1 along the length direction X of the battery slot 11. When the dry cell is installed in the battery slot 11, the reinforcement member 2 generates a pulling force pointing to the inside of the shell 1 on the opposite sides of the shell 1. This pulling force is used to offset the pressing force generated by the dry cell on the side wall of the shell 1, so as to prevent the side wall of the shell 1 from structural deformation and ensure the structural integrity of the battery box 10.

[0043] See again Figure 3 The reinforcement member 2 includes a first portion 21 and a plurality of second portions 22 . The first portion 21 is connected to opposite sides of the housing 1 along the length direction X of the battery slot 11 , and the plurality of second portions 22 are connected to opposite sides of the first portion 21 .

[0044] In one embodiment, the first part 21 is respectively connected to the opposite sides of the shell 1 along the length direction X of the battery groove 11, and mainly plays the role of tightening the opposite sides of the shell 1. Multiple second parts 22 can be evenly spaced and connected to the opposite sides of the first part 21. Specifically, the first part 21 is connected to the opposite sides of the first groove 111 and the second groove 112 with multiple second parts 22. The second part 22 can increase the structural strength of the first part 21 and further strengthen the tightening effect of the first part 21 on the shell 1; at the same time, the second part 22 is located in the first groove 111 and the second groove 112. When the battery is installed in the first groove 111 and the second groove 112, the second part 22 can also support the battery and play the role of limiting the battery.

[0045] See again Figure 3 The battery box 10 also includes a support portion 5, which is connected to the housing 1 and is located in the battery slot 11. The support portion 5 is used to support the battery.

[0046] In one embodiment, a support portion 5 is provided in both the first groove 111 and the second groove 112, and the support portion 5 includes a curved surface 51. When the battery is installed in the first groove 111 or the second groove 112, the curved surface 51 fits with the outer peripheral surface of the battery to facilitate supporting the battery. The support portion 5 and the second portion 22 are respectively located on opposite sides of the battery, and together support the battery from opposite sides of the battery, further realizing a limiting effect on the battery, avoiding shaking of the battery, and ensuring the installation stability of the battery.

[0047] See also Figure 4 and Figure 5 The reinforcement 2 is provided with an avoidance groove 211, which is provided at the end where the reinforcement 2 is connected to the shell 1; the battery box 10 also includes a battery connector 6, which includes a first electrical contact portion 61, a second electrical contact portion 62 and a connecting portion 63. The first electrical contact portion 61 and the second electrical contact portion 62 are respectively arranged in the first groove 111 and the second groove 112, and are respectively used to contact the positive and negative poles of two adjacent batteries. The connecting portion 63 connects the first electrical contact portion 61 and the second electrical contact portion 62, and the avoidance groove 211 is used to avoid the connecting portion 63.

[0048] In one embodiment, a plurality of dry cells may be installed in the battery box 10 to improve the battery life of the battery box 10. In order to conveniently connect each dry cell to the circuit, the present application provides a battery connector 6, which is used to connect two adjacent dry cells to achieve electrical conduction between the two dry cells. Then, one of the dry cells is connected to the circuit to achieve the function of connecting the two dry cells to the circuit.

[0049] Specifically, the battery connector 6 includes a first electrical contact portion 61, a second electrical contact portion 62 and a connecting portion 63, wherein the first electrical contact portion 61 and the second electrical contact portion 62 are connected together through the connecting portion 63, and the first electrical contact portion 61 and the second electrical contact portion 62 are respectively arranged in the first groove 111 and the second groove 112, wherein the positive pole of one of the two adjacent dry batteries is connected to the first electrical contact portion 61, and the negative pole of the other is connected to the second electrical contact portion 62, so as to realize the series connection of the two dry batteries; and the reinforcement 2 is provided with an avoidance groove 211, and the avoidance groove 211 is used to avoid the connecting portion 63. The design of the avoidance groove 211 makes the installation of the battery connector 6 more convenient, and at the same time, it can also retain the connection between the reinforcement 2 and the shell 1, so that the reinforcement 2 can tighten the opposite sides of the shell 1 to prevent the battery from pushing the shell 1 out of shape.

[0050] Understandably, see Figure 6 The battery box 10 also includes a power connection part 8. When the battery connector 6 connects multiple dry batteries together in sequence, the power connection part 8 is connected to one of the dry batteries and connected to the circuit to connect multiple dry batteries to the circuit.

[0051] See again Figure 5 The battery box 10 includes a limiting portion 3, at least one of the shell 1 and the reinforcement 2 is connected to the limiting portion 3, the limiting portion 3 is provided with a limiting groove 31, and the limiting groove 31 is used to limit the battery connector 6.

[0052] In one embodiment, the battery connector 6 is usually located at the end of the dry battery, that is, at the inner wall of the shell 1. In order to fix the battery connector 6, the inner wall of the shell 1 can be provided with multiple limiting portions 3. For example, the shell 1 is respectively provided with limiting portions 3 at the positions of the first electrical contact portion 61 and the second electrical contact portion 62. The limiting portion 3 is provided with a limiting groove 31. The first electrical contact portion 61 and the second electrical contact portion 62 are at least partially located in the limiting groove 31. The limiting groove 31 is used to limit the first electrical contact portion 61 and the second electrical contact portion 62.

[0053] The reinforcement 2 may also be provided with a limiting portion 3. For example, the reinforcement 2 is provided with limiting portions 3 at the positions of the first electrical contact portion 61 and the second electrical contact portion 62 respectively. The limiting portion 3 is provided with a limiting groove 31. The first electrical contact portion 61 and the second electrical contact portion 62 are at least partially located in the limiting groove 31, and the limiting groove 31 can be connected to the avoidance groove 211. In this way, the limiting portion 3 can also limit the connecting portion 63, thereby effectively preventing the battery connector 6 from falling off.

[0054] It is understandable that the housing 1 and the reinforcement 2 may also be provided with the limiting portion 3 at the same time, so as to further strengthen the limiting effect on the battery connector 6 .

[0055] See again Figure 5The battery box 10 includes a limiting protrusion 4, and the shell 1 is connected to the limiting protrusion 4 on one side of the limiting portion 3. The limiting protrusion 4 extends into the battery groove 11, and the limiting protrusion 4 is used to limit the battery connector 6 from leaving the limiting groove 31.

[0056] In one embodiment, the limiting protrusion 4 cooperates with the limiting portion 3 to jointly limit the battery connector 6 to prevent the battery connector 6 from falling out of the limiting groove 31; specifically, the limiting protrusion 4 and the limiting portion 3 can respectively limit the battery connector 6 from falling out of the limiting groove 31 from different directions. For example, the limiting portion 3 can limit the battery connector 6 from the length direction and thickness direction of the battery connector 6, and the limiting protrusion 4 can limit the battery connector 6 from the height direction of the battery connector 6. In this way, the battery connector 6 is limited from falling out from multiple directions, the battery connector 6 is fixed, and this method is convenient for the installation of the battery connector 6.

[0057] See also Figure 7 The battery box 10 includes a circuit component 7. The housing 1 is provided with a receiving groove 12. The circuit component 7 is installed in the receiving groove 12. The circuit component 7 is used to convert the output voltage of the battery.

[0058] In one embodiment, the shell 1 is provided with a receiving groove 12, and the receiving groove 12 is used to install the circuit component 7. The circuit component 7 is electrically connected to the battery in the battery slot 11, and can convert the output voltage of the battery so that the output voltage of different types of battery boxes 10 is consistent, so that different types of battery boxes 10 can be installed in the installation groove 201 of the middle frame 20, for example, dry cell battery boxes and lithium battery boxes can be installed. Through the circuit conversion function of the circuit component 7, the final output voltage is consistent, so that the middle frame 20 can adapt to both dry cell battery boxes and lithium battery boxes.

[0059] See also Figure 8 The housing 1 includes a main body 13 and a cover plate 14 . The main body 13 is provided with a battery slot 11 and a receiving slot 12 . The cover plate 14 is connected to the main body 13 and covers the receiving slot 12 .

[0060] In one embodiment, the main body 13 and the cover 14 can be connected in a detachable manner. The cover 14 mainly protects the circuit component 7 inside the accommodating groove 12 to prevent the circuit component 7 from being damaged, and hides the circuit component 7 to ensure that the circuit component 7 is not exposed, thereby improving the aesthetics. During use, the internal circuit component 7 can be maintained by removing the cover 14, which is convenient for operators to perform maintenance work.

[0061] In one embodiment, the housing 1 further comprises a fixing member 15. When the cover plate 14 is covered on the receiving groove 12, the fixing member 15 connects the cover plate 14 and the main body 13 respectively and is used to fix the cover plate 14 and the main body 13 together. The fixing member 15 can be a screw or the like.

[0062] See again Figure 8 The battery box 10 also includes a terminal 9 , which is disposed on the outer side of the cover plate 14 and is electrically connected to the circuit component 7 .

[0063] The terminal 9 is arranged on the outside of the cover plate 14, that is, the terminal 9 is exposed to the battery box 10. With this arrangement, when the battery box 10 is installed in the middle frame 20, it is convenient to connect the terminal 9 to the electronic components in the middle frame to realize the power supply function of the battery box 10.

[0064] The present application also provides a smart door lock, including the above-mentioned battery mounting structure and door lock housing, the battery mounting structure is arranged in the door lock housing, and a door lock host is also arranged in the door lock housing, the connection terminal 9 of the battery mounting structure is electrically connected to the door lock host, so that the battery box 10 supplies power to the door lock host. With this battery mounting structure, the battery of the smart door lock of the present application will not impact the battery cover or the door lock cover plate when the door is slammed or hit, effectively preventing the battery from detaching from the battery slot 11, thereby improving the drop resistance and practicality of the smart door lock.

[0065] Different from the prior art, the embodiment of the present application provides a smart door lock and a battery installation structure. The battery installation structure is arranged in the door lock housing. The battery installation structure includes a battery box 10 and a middle frame 20. The battery box 10 includes a housing 1. At least one side of the housing 1 is provided with a battery pairing groove 11. The middle frame 20 is provided with a mounting groove 201. The mounting groove 201 is used to accommodate the housing 1. When the housing 1 is arranged in the mounting groove 201, the battery pairing groove 11 is arranged opposite to the groove wall of the mounting groove 201. Compared with the prior art, the present application arranges the battery pairing groove 11 and the groove wall of the mounting groove 201 opposite to each other. In this way, even if the electronic product is impacted by external force during use, the groove wall of the mounting groove 201 arranged opposite to each other plays a limiting role on the battery, effectively preventing the battery from being separated from the battery pairing groove 11. At the same time, the battery pairing groove 11 and the groove wall of the mounting groove 201 are arranged opposite to each other, which can also play a role in hiding electrical components such as batteries. When the battery installation structure is opened, the groove wall of the mounting groove 201 covers the battery pairing groove 11, and the battery will not be exposed, thereby improving the aesthetics of the device. The smart door lock using the above-mentioned battery installation structure can effectively prevent the battery from being separated from the battery slot 11 due to slamming the door or collision, thereby improving the practicality of the smart door lock.

[0066] The above is only a specific implementation of the present application.
