This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0035] In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0036] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.

[0037] Please refer to Figure 1 , in the embodiment of the present application, a battery compartment assembly 11 is provided. The battery compartment assembly 11 can be applied to a door lock 10, especially an intelligent door lock. The battery compartment assembly 11 is used to provide an assembly space for energy structures such as batteries, and after the energy structures such as batteries are installed in the battery compartment assembly 11, the battery compartment assembly 11 can supply electrical energy to the door lock 10 to realize the functions of the door lock 10.

[0038] Among them, the battery compartment assembly 11 provided in this embodiment can improve the problem in the prior art that the door lock is prone to water ingress and short - circuit failure. Based on this, the door lock 10 using the battery compartment assembly 11 can also improve the problem in the prior art that the door lock is prone to water ingress and failure.

[0039] It should be noted that in this embodiment, the application of the battery compartment assembly 11 to an intelligent door lock is taken as an example for illustration. Among them, the intelligent door lock includes two parts. One part is arranged outside the door, and the other part is arranged inside the door (when the door closes the designated space, the inside of the door refers to the area inside the designated space, and the outside of the door refers to the area outside the designated space); and the battery compartment assembly 11 in this embodiment is arranged in the part inside the door.

[0040] In this embodiment, the battery compartment assembly 11 includes a housing 100, a battery compartment 200, a circuit board 500, a waterproof pad 300, and a cover plate 400. The housing 100 is used to be mounted on the door. In some other embodiments, the housing 100 may also be referred to as a rear panel. Among them, the housing 100 is provided with a receiving groove 110. The battery compartment 200 is used to accommodate an energy structure such as a battery; and the battery compartment 200 is disposed inside the receiving groove 110. The circuit board 500 is disposed inside the receiving groove 110, and the circuit board 500 is provided with an electrical connection portion which fits against the end wall of the wire harness hole 113 and isolates the receiving groove 110 and the wire harness hole 113. The waterproof pad 300 is disposed inside the receiving groove 110 and covers the battery compartment 200. During the process of loading the battery compartment 200 and the waterproof pad 300 into the receiving groove 110, first place the battery compartment 200 at the bottom of the receiving groove 110, and then place the waterproof pad 300 in the receiving groove 110 and above the battery compartment 200 (with the direction from the bottom wall to the opening of the receiving groove 110 as the up and down direction). Thus, the waterproof pad 300 covers the battery compartment 200. The cover plate 400 is connected to the housing 100 and seals the receiving groove 110; the cover plate 400 presses on the waterproof pad 300.

[0041] As described above, in the battery compartment assembly 11, the circuit board 500 fits against the end wall of the wire harness hole 113 through the electrical connection portion, thereby realizing the closure of the wire harness hole 113, and further isolating the receiving groove 110 and the wire harness hole 113; based on this, even if the outside part of the door lock is flooded, since the wire harness hole 113 is closed and isolated from the receiving groove 110, water can be prevented from entering the receiving groove 110 from the wire harness hole 113, and the problem of short circuit caused by the battery compartment assembly 11 being flooded can be prevented. Therefore, the battery compartment assembly 11 provided in this embodiment can improve the problem in the prior art that the door lock is prone to water ingress and short circuit, resulting in failure.

[0042] In addition, after the assembly is completed, the cover plate 400 presses the waterproof pad 300 at the opening of the receiving groove 110. In the squeezed state, the waterproof pad 300 can effectively seal the opening of the receiving groove 110, thereby preventing water from entering the inside of the receiving groove 110 from the opening of the receiving groove 110, and further preventing the electrical components inside the battery compartment 200 from being corroded, and the problem of power supply failure caused by the corrosion of the electrical components can be avoided. Based on this, the battery compartment assembly 11 provided by the present utility model can improve the problem in the prior art that the waterproof performance of the door lock is poor, resulting in the electrical components such as the battery in the battery compartment being easily corroded, causing power supply failure.

[0043] It should be noted that, in this embodiment, the area of the waterproof pad 300 is equivalent to the opening area of the receiving groove 110. Thus, when the waterproof pad 300 is pressed by the cover plate 400, it can effectively cover the opening of the receiving groove 110, and can effectively prevent external water from entering the interior of the receiving groove 110 through the gap. Among them, the area of the waterproof pad 300 being equivalent to the opening area of the receiving groove 110 can refer to: firstly, the area of the waterproof pad 300 is equal to the opening area of the receiving groove 110 when the waterproof pad 300 is not pressed; or, secondly, the area of the waterproof pad 300 is equal to the opening area of the receiving groove 110 when the waterproof pad 300 is pressed by the cover plate 400. In this case, if the waterproof pad 300 is not pressed, the area of the waterproof pad 300 can be slightly smaller than the opening area of the receiving groove 110.

[0044] In addition, optionally, the waterproof pad 300 can be made of silica gel material, or can be made of other deformable waterproof materials, such as rubber material, etc.

[0045] Optionally, in this embodiment, the receiving groove 110 includes a first receiving cavity 111 and a second receiving cavity 112. The first receiving cavity 111 is opened on the bottom wall of the first receiving cavity 111 to make the receiving groove 110 form a stepped groove. Among them, the opening of the first receiving cavity 111 is located on the bottom wall of the second receiving cavity 112, or it can be considered that the first receiving cavity 111 extends and is opened from the bottom wall of the second receiving cavity 112 in a direction away from the opening of the second receiving cavity 112. And, the opening area of the first receiving cavity 111 is smaller than the bottom wall area of the second receiving cavity 112, so that the first receiving cavity 111 and the second receiving cavity 112 together form a stepped structure, which makes the receiving groove 110 form a stepped groove. Among them, the battery compartment 200 is arranged in the first receiving cavity 111; the waterproof pad 300 is arranged on the bottom wall of the second receiving cavity 112, and the cover plate 400 is arranged in the second receiving cavity 112 and presses the waterproof pad 300 together with the bottom wall of the second receiving cavity 112.

[0046] When the waterproof pad 300 is pressed on the bottom wall of the second receiving cavity 112, the waterproof pad 300 can effectively seal the opening of the first receiving cavity 111, thereby realizing the effective sealing of the first receiving cavity 111 and preventing external water from entering the first receiving cavity 111 from the opening of the first receiving cavity 111.

[0047] It should be noted that the depth of the second receiving cavity 112 is relatively small. Thus, it can be considered that the second receiving cavity 112 is at the opening of the receiving groove 110, which also makes the cover plate 400 and the waterproof pad 300 arranged at the opening of the receiving groove 110. Of course, in other embodiments, if the depth of the second receiving cavity 112 is increased according to actual needs, at this time, the waterproof pad 300 and the cover plate 400 can also be considered to be arranged at the middle position of the receiving groove 110.

[0048] In this embodiment, an installation hole 1121 is formed in the bottom wall of the second accommodation cavity 112; the battery compartment assembly 11 further includes a connecting member 410, and the connecting member 410 passes through the cover plate 400 and cooperates with the installation hole 1121 to fix the cover plate 400. Optionally, the connecting member 410 can be a bolt, and the bolt realizes the assembly of the cover plate 400 and the housing 100 through cooperation with the installation hole 1121. While the connecting member 410 realizes the fastening connection between the cover plate 400 and the housing 100, it can also achieve the purpose of pressing the waterproof pad 300 by the cover plate 400, so that the waterproof pad 300 is compressed to efficiently close the opening of the accommodation groove 110.

[0049] It should be understood that in other embodiments, the connecting member 410 can also adopt other structures, for example, a rivet.

[0050] In addition, in other embodiments, the cover plate 400 can also be assembled and connected to the housing 100 in other ways. For example, one side of the cover plate 400 is rotatably connected to the housing 100, and the connection position is on the side wall of the second accommodation cavity 112; and a clamping structure is provided on the other side of the cover plate 400. Correspondingly, a buckle adapted to the clamping structure is also provided on the second accommodation cavity 112, and the cover plate 400 and the assembly connection are realized through the fastening of the clamping structure and the buckle.

[0051] Optionally, in this embodiment, a through hole 310 for the connecting member 410 to pass through is formed in the waterproof pad 300. In order to facilitate, it can facilitate the connecting member 410 to pass through the waterproof pad 300 to assemble and install the cover plate 400. On the other hand, when the connecting member 410 passes through the waterproof pad 300, it can provide a limiting effect on the waterproof pad 300 to prevent the problem that the position of the waterproof pad 300 is displaced during use, resulting in the influence on the sealing effect. Based on this, the stable waterproof function of the waterproof pad 300 can be ensured, and the sealing performance can be improved.

[0052] Furthermore, in this embodiment, please refer to Figure 2 and Figure 3 , in order to further prevent the problem that the wiring harness hole 113 leaks water and affects the battery compartment 200, a sealing structure is filled in the wiring harness hole 113. By closing the wiring harness hole 113 with the sealing structure, the problem that the rear side of the housing 100 enters water and affects the electrical components can be prevented, the overall sealing performance of the housing 100 can be further improved, and the problem that the electrical components are corroded by water and cause power supply failure can be prevented.

[0053] Optionally, the sealing structure can also be made of silicone material or other sealing coatings, which can be filled in the wiring harness hole 113 and achieve sealing.

[0054] Further, a protruding portion 115 is also provided on the housing 100. The protruding portion 115 protrudes outside the bottom of the accommodating groove 110, and the wire harness hole 113 penetrates through the protruding portion 115. That is to say, the protruding portion 115 and the battery compartment 200 are respectively arranged on opposite sides of the bottom wall of the accommodating groove 110. By extending the wire harness hole 113 through the protruding portion 115, the internal space volume of the wire harness hole 113 can be increased. On the one hand, it is convenient to fill the sealing structure in the wire harness hole 113; on the other hand, the sealing effect of the wire harness hole 113 can also be improved.

[0055] It should be understood that in other embodiments of the present application, the protruding portion 115 may also protrude inside the accommodating groove 110; or, protruding portions 115 may be provided both inside and outside the accommodating groove 110.

[0056] In this embodiment, please refer to Figure 4 , a limiting plate 116 is provided in the accommodating groove 110. The limiting plate 116 divides the internal space of the accommodating groove 110 into two regions, and the two regions are respectively located on opposite sides in the thickness direction of the limiting plate 116. Among them, the battery compartment 200 and the circuit board 500 are respectively located on both sides of the limiting plate 116, that is to say, the battery compartment 200 and the circuit board 500 are respectively located in the two regions. It should be noted that one side of the battery compartment 200 abuts against the inner wall of the accommodating groove 110, and the other side abuts against the limiting plate 116. The limiting plate 116 and the inner wall of the accommodating groove 110 can jointly provide a clamping effect on the battery compartment 200 to ensure the stability of the battery compartment in the accommodating groove 110 and prevent the situation that the battery loosens or the wire is damaged due to the shaking of the battery compartment 200.

[0057] In addition, please refer to Figure 4 , Figure 5 and Figure 6 In this embodiment, a wiring groove 114 is further formed on the bottom wall of the accommodating groove 110. The wiring groove 114 is located below the limiting plate 116, so that part of the wiring groove 114 is located at the bottom of the battery compartment 200, and part of the wiring groove 114 corresponds to the circuit board 500 and is arranged below the circuit board 500; it should be noted that in this embodiment, the formation of the wiring groove 114 can be regarded as a groove formed by the bottom wall of the accommodating groove 110 being recessed outward. At the same time, a protrusion is formed on the outside of the bottom wall of the accommodating groove 110, and this protrusion is connected to the above-mentioned protruding portion 115; of course, this protrusion can also be regarded as a part of the protruding portion 115.

[0058] A wiring hole 210 is formed at the bottom of the battery compartment 200, as shown in Figure 7 and Figure 8, the wire passing hole 210 corresponds to the wire trough 114. The wire harness inside the battery compartment 200 can be led out from the wire passing hole 210 and then connected to the circuit board 500 through the wire trough 114. Among them, in this embodiment, two clamping structures for clamping the electrical connection piece are provided on the end plate of the battery compartment 200 close to the limiting plate 116. The electrical connection piece is used for electrically connecting with the battery in the battery compartment 200 so that the batteries can be connected in series. And the wire passing hole 210 is opened on the bottom wall corresponding to the area between the two clamping structures, such as Figure 7 and Figure 8 .

[0059] In the case where the battery compartment 200 leads out wires from the wire passing hole 210, the wires can be led out through the wire trough 114, and wire avoidance can be achieved, which is convenient for the battery compartment 200 to fit on the bottom wall of the accommodating groove 110.

[0060] Based on the battery compartment assembly 11 provided above, please refer to Figure 4 , in this embodiment, a door lock 10 is further provided. Preferably, the door lock 10 is an intelligent door lock. In the case of adopting the above battery compartment assembly 11, the door lock 10 provided in this embodiment can improve the problem in the prior art that the waterproof performance of the door lock is not good, resulting in the electrical components such as the battery in the battery compartment being easily corroded, thereby causing power supply failure.

[0061] To sum up, for the battery compartment assembly 11 and the door lock 10 provided in this embodiment, after assembly, the cover plate 400 presses the waterproof pad 300 at the opening of the accommodating groove 110. The waterproof pad 300 can effectively seal the opening of the accommodating groove 110 in the squeezed state, thereby preventing water from entering the inside of the accommodating groove 110 from the opening of the accommodating groove 110, and further preventing the electrical components inside the battery compartment 200 from being corroded, and avoiding the problem of power supply failure caused by the corrosion of the electrical components. Based on this, the battery compartment assembly 11 provided by the present invention can improve the problem in the prior art that the waterproof performance of the door lock is not good, resulting in the electrical components such as the battery in the battery compartment being easily corroded, thereby causing power supply failure. And by filling a sealing structure in the wire harness hole 113, the problem that the electrical components are affected by the water entering from the rear side of the housing 100 can be avoided, thereby further improving the problem in the prior art that the waterproof performance of the door lock is not good, resulting in the electrical components such as the battery in the battery compartment being easily corroded, thereby causing power supply failure.

[0062] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
