[0028] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.
[0029] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0030] The door lock and door provided in the embodiment of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.
[0031] Please refer to Figures 1 to 11 As shown, an embodiment of the present application discloses a door lock, including: a lock body 100, a battery assembly 200, a display module 300 and a connector 400.
[0032] Specifically, the battery assembly 200 includes a battery 210 . A receiving slot 121 for receiving the battery assembly 200 is disposed on one side of the lock body 100 , and the battery assembly 200 can enter and exit the receiving slot 121 from a notch of the receiving slot 121 .
[0033] The display module 300 is rotatably disposed on the lock body 100. When the display module 300 is rotated to the first position, the display module 300 blocks the notch and is detachably connected to the lock body 100 through the connecting member 400, thereby realizing the locking of the display module 300. When the display module 300 is rotated to the second position, the display module 300 and at least a portion of the notch are offset from each other, and the battery 210 can be moved out of the accommodating groove 121.
[0034] In the embodiment of the present application, the display module 300 is rotatably disposed on the lock body 100. When the display module 300 is rotated to the second position, the display module 300 and at least a portion of the notch are staggered, and the battery 210 can be removed from the receiving slot 121. That is, when the display module 300 is rotated to the second position, the user can replace the battery 210. In this arrangement, when the battery 210 is replaced, the display module 300 is still disposed on the lock body 100, so that the risk of losing the display module 300 is low.
[0035] In the embodiment of the present application, when the connection between the connecting member 400 and the lock body 100 is released, the display module 300 is disconnected from the lock body 100, and the display module 300 can rotate freely. When the display module 300 is connected to the lock body 100 through the connecting member 400, the position of the display module 300 is locked and cannot rotate. Figure 1 As shown, when the display module 300 rotates to the first position, the outer surface of the display module 300 is, for example, flush with the outer surface of the lock body 100 .
[0036] In another embodiment, reference Figures 1 to 3 As shown, the battery assembly 200 also includes a battery compartment 220, the inner cavity of the battery compartment 220 is used to accommodate the battery 210, and the battery compartment 220 is provided with an inlet and outlet for the battery 210 to enter and exit its inner cavity. The battery compartment 220 is connected to the display module 300. When the display module 300 is in the first position, the battery compartment 220 is located in the receiving groove 121. When the display module 300 is rotated to the second position, the inlet and outlet are located outside the receiving groove 121, so as to facilitate the battery 210 to be moved out of the receiving groove 121.
[0037] The solution adopted in this embodiment is that the inlet and outlet of the battery compartment 220 are synchronously moved out from the accommodating groove 121 as the display module 300 rotates. Compared with the solution of rotating the display module 300 to the second position and then moving the inlet and outlet from the inside of the accommodating groove 121, the solution adopted in this embodiment is that the user can synchronously change the position of the battery compartment 220 by rotating the display module 300 without having to take out the battery compartment 220 separately. The operation is simpler and the user experience is better.
[0038] In other optional embodiments, the battery compartment 220 and the display module 300 may also be separately provided.
[0039] As a specific implementation method, refer to Figure 6 and Figure 7 As shown, the battery compartment 220 is provided with a rotating shaft 710 , and the lock body 100 is provided with a connecting seat 720 . The display module 300 is rotatably arranged on the lock body 100 by rotatably connecting the rotating shaft 710 and the connecting seat 720 .
[0040] In a further embodiment, reference Figure 2 and Figure 3 As shown, the first end of the display module 300 is rotatably disposed on the lock body 100, and an inlet and outlet are disposed at the end of the battery compartment 220 opposite to the second end of the display module 300. The first end and the second end are two opposite ends of the display module 300 along a first direction, and the first direction is perpendicular to the rotation axis of the display module 300 and the thickness direction of the display module 300. It should be noted that the end of the battery compartment 220 opposite to the second end of the display module 300 refers to the end of the battery compartment 220 and the second end of the display module 300 located on the same side, that is, the end of the battery compartment 220 and the second end of the display module 300 are both far away from the first end of the display module 300.
[0041] The solution adopted in this embodiment is that when the display module 300 rotates to the second position, compared with other positions of the display module 300, the distance between the second end of the display module 300 and the lock body 100 is the largest. In this way, the inlet and outlet are arranged at the end of the battery compartment 220 opposite to the second end of the display module 300. When the display module 300 rotates to the second position, there is a larger space between the inlet and outlet and the lock body 100, so that the replacement of the battery 210 is more convenient.
[0042] In other optional embodiments, the third end and the fourth end of the battery compartment 220 are respectively opposite to the first end and the second end of the display module 300 , and the inlet and outlet are, for example, disposed between the third end and the fourth end of the battery compartment 220 .
[0043] In another embodiment, reference Figures 5 to 7 As shown, one of the display module 300 and the lock body 100 is provided with a sliding portion 221 , and the other is provided with a guiding portion 122 . The sliding portion 221 and the guiding portion 122 are slidably matched in the length direction of the guiding portion 122 .
[0044] The solution adopted in this embodiment can prevent the display module 300 from shaking during the rotation process by making the sliding part 221 and the guiding part 122 slide together, so that the stability of the display module 300 is better.
[0045] In other optional embodiments, the sliding portion 221 and the guiding portion 122 may not be provided.
[0046] In a further embodiment, when the display module 300 is in the first position, the sliding portion 221 cooperates with the first end face of the guide portion 122 in the upper limit position in the length direction of the guide portion 122, and when the display module 300 is in the second position, the sliding portion 221 cooperates with the second end face of the guide portion 122 in the upper limit position in the length direction of the guide portion 122, and the first end face and the second end face are two opposite end faces in the length direction of the guide portion 122.
[0047] The solution adopted in this embodiment is that when the sliding part 221 cooperates with the first end face limit, it indicates that the display module 300 is rotated to the first position, and when the sliding part 221 cooperates with the second end face limit, it indicates that the display module 300 is rotated to the second position, so that the user can more accurately determine the detailed positions of the first position and the second position, and thus save the time spent on finding the first position and the second position, and the user can rotate the display module 300 to the first position or the second position more quickly.
[0048] In other optional embodiments, there may not be a limiting fit relationship between the sliding portion 221 and the first end surface and the second end surface of the guiding portion 122 .
[0049] As a specific implementation, the sliding portion 221 described above is, for example, a convex column, the guide portion 122 is, for example, a through groove, and the through groove is, for example, an arc-shaped structure. In addition, the guide portion 122 is, for example, provided on the lock body 100, and the sliding portion 221 is, for example, provided on the display module 300. More specifically, the sliding portion 221 is, for example, provided on the battery compartment 220 described above, and thus indirectly provided on the display module 300.
[0050] In a further embodiment, reference Figure 7 As shown, the guide portion 122 is provided with a limiting portion 1222, and the limiting portion 1222 is located between the first end face and the second end face, so as to separate the guide portion 122 into a guide segment 1221 and a clamping segment arranged in sequence and connected along the length direction of the guide portion 122, and the sliding portion 221 and the guide segment 1221 slide and cooperate in the length direction of the guide portion 122, and when the display module 300 is in the second position, the sliding portion 221 is clamped in the clamping segment. In this way, under the clamping action of the clamping segment, the display module 300 can be maintained in the second position, so that when replacing the battery 210, the user does not need to manually fix the position of the display module 300, thereby making the replacement of the battery 210 more convenient. In other words, when the display module 300 is in the second position, the two opposite sides of the sliding portion 221 are respectively limited and cooperated with the second end face and the limiting portion 1222, so as to limit the position of the display module 300 in more directions.
[0051] In other optional embodiments, the limiting portion 1222 may not be provided.
[0052] Specifically, the limiting portion 1222 is made of a deformable material, such as a limiting bump, and more specifically, made of a rubber material. During use, when the sliding portion 221 needs to be moved out of the clamping section, the user applies a force to the display module 300, and under the action of the force, the limiting portion 1222 is deformed, so that the sliding portion 221 can be moved out of the clamping section.
[0053] In another embodiment, reference Figures 4 to 7 As shown, the lock body 100 includes a first frame 110 and a second frame 120, the second frame 120 is arranged inside the first frame 110, and is detachably connected to the first frame 110, and the second frame 120 is provided with a sliding portion 221 or a guide portion 122. In this way, when one of the first frame 110 and the second frame 120 is damaged, only the damaged one needs to be replaced, and the first frame 110 and the second frame 120 do not need to be replaced as a whole, thereby reducing waste and saving costs. In addition, in this way, when the second frame 120 is provided with a guide portion 122, and the guide portion 122 is the through groove described above, the guide portion 122 is hidden inside the first frame 110 as a whole, and the first frame 110 can protect the guide portion 122 from external interference.
[0054] In other optional embodiments, the first frame body 110 and the second frame body 120 may also be an integrated structure.
[0055] As a specific implementation, the connecting seat 720 mentioned above and the guiding portion 122 mentioned above are both disposed on the second frame body 120 , for example.
[0056] In another embodiment, reference Figures 9 to 11 As shown, the door lock further includes a first circuit board 510, which is disposed inside the lock body 100. The display module 300 is electrically connected to one end of a first wire 520, and the other end of the first wire 520 is electrically connected to the first circuit board 510. The length of the first wire 520 is greater than or equal to the distance between the display module 300 and the first circuit board 510 when the display module 300 is in the second position. In this way, the length of the first wire 520 is sufficient to match the rotation amplitude of the display module 300, so when the position of the display module 300 is switched, there is no need to disconnect the connection between the first wire 520 and the first circuit board 510, so that the replacement of the battery 210 is more convenient.
[0057] In other optional embodiments, the length of the first wire 520 may also be smaller than the distance between the display module 300 and the first circuit board 510 when the display module 300 is in the second position.
[0058] In addition, it should be noted that the display module 300 of a traditional door lock is usually connected to the lock body 100 by means of screws, and the display module 300 of the traditional door lock is separately arranged from the battery assembly 200, and the display module 300 is electrically connected to the main circuit board of the door lock by means of a plug-in connection, and the main circuit board is electrically connected to the battery 210. Therefore, when replacing the battery 210, it is necessary to first remove the display module 300. During the process of removing the display module 300, the battery 210 still supplies power to the display module 300 through the main circuit board, so that the display module 300 is unplugged from the main circuit board while it is powered, which leads to a higher probability of damage to the display module 300. Compared with this solution, in the solution adopted in this embodiment, during the process of replacing the battery 210, the circuit between the display module 300 and the first circuit board 510 is continuously turned on, and the display module 300 and the lock body 100 are always connected. Therefore, compared with the traditional door lock, the display module 300 in this embodiment does not exist in the situation where it is removed from the lock body 100 while being charged, and thus the probability of damage to the display module 300 in this embodiment is lower.
[0059] As a specific implementation method, Fig.10 and Fig.11 In the embodiment, the number of the first wires 520 is two. It is understandable that the number of the first wires 520 can be any number and can be set according to actual needs.
[0060] In another embodiment, reference Figures 9 to 11 As shown, the door lock further includes a first circuit board 510, and the first circuit board 510 is disposed inside the lock body 100. The battery assembly 200 further includes a second circuit board 530 connected to the battery 210, the second circuit board 530 is electrically connected to one end of a second wire 540, and the other end of the second wire 540 is electrically connected to the first circuit board 510, and the length of the second wire 540 is greater than or equal to the distance between the second circuit board 530 and the first circuit board 510 when the display module 300 is in the second position. As described above, in such a configuration, the length of the second wire 540 is sufficient to match the rotation amplitude of the display module 300, so when the position of the display module 300 is switched, there is no need to disconnect the connection between the second wire 540 and the first circuit board 510, so that the replacement of the battery 210 is more convenient.
[0061] It should be noted that, in the present embodiment, the connection between the second circuit board 530 and the battery 210 means that the two are connected together by a mechanical connection method, such as screws or adhesives, and at the same time the two are electrically connected and the circuit between the two is conductive.
[0062] In other optional embodiments, the length of the second wire 540 may also be smaller than the distance between the second circuit board 530 and the first circuit board 510 when the display module 300 is in the second position.
[0063] In an optional embodiment, while the length of the second wire 540 is greater than or equal to the distance between the second circuit board 530 and the first circuit board 510 when the display module 300 is in the second position, the length of the first wire 520 may also be greater than or equal to the distance between the display module 300 and the first circuit board 510 when the display module 300 is in the second position.
[0064] In another embodiment, the door lock further includes an elastic member, such as a spring.
[0065] One of the display module 300 and the lock body 100 is slidably matched with the connecting member 400 along the second direction, and is connected to the connecting member 400 through an elastic member so that the connecting member 400 can be automatically reset. The other of the display module 300 and the lock body 100 is provided with a clamping portion 123, and the second direction is parallel to the rotation axis of the display module 300.
[0066] When the display module 300 is in the second position, when the connecting member 400 is in the third position, the connecting member 400 is engaged in the engaging portion 123 , and when the connecting member 400 is in the fourth position, the connecting member 400 is separated from the engaging portion 123 .
[0067] During specific use, when the display module 300 is in the second position, the connector 400 is pressed, the connector 400 slides along the second direction, and switches from the third position to the fourth position, thereby separating from the clamping portion 123, and the elastic member is deformed by force during this process. Conversely, the connector 400 is released, and under the elastic force of the elastic member, the connector 400 switches from the fourth position to the third position, and the connector 400 automatically resets and re-clamps into the clamping portion 123. It can be seen that the solution adopted in this embodiment can connect or disconnect the display module 300 and the lock body 100 manually without the aid of tools, thereby making it more convenient to replace the battery 210.
[0068] In other optional embodiments, the display module 300 may be detachably connected to the lock body 100 by means of a connecting member 400 such as a screw.
[0069] As a specific implementation, the display module 300 and the connecting member 400 are slidably matched along the second direction, and the lock body 100 is provided with a clamping portion 123, and the clamping portion 123 is, for example, a clamping slot, and the connecting member 400 has, for example, a clamping tooth. During specific use, the connecting member 400 is clamped into the inside of the clamping portion 123 by making the clamping tooth engage in the clamping slot, or the clamping tooth is disengaged from the inside of the clamping slot under the action of external force to achieve the separation of the connecting member 400 from the clamping portion 123.
[0070] Furthermore, the battery compartment 220 described above is provided with a guide groove extending along the second direction, for example, and the elastic member and the connecting member 400 are both provided in the guide groove and slide in cooperation with the guide groove along the second direction, thereby realizing the sliding cooperation between the display module 300 and the connecting member 400 along the second direction. It can be understood that the sliding cooperation between the display module 300 and the connecting member 400 can be a direct sliding cooperation between the display module 300 and the connecting member 400, or an indirect sliding cooperation between the two, such as the above-mentioned sliding cooperation between the guide groove and the connecting member 400 along the second direction.
[0071] In another embodiment, reference Figures 1 to 3 As shown, the door lock further includes a camera module 600, which is separately arranged from the display module 300, and the camera module 600 is connected to the lock body 100. In this arrangement, the camera module 600 and the display module 300 are independent of each other and do not interfere with each other, so that the rotation of the display module 300 can be prevented from affecting the operation of the camera module 600.
[0072] In other optional embodiments, the camera module 600 and the display module 300 may also be an integrated structure.
[0073] As a specific implementation, the camera module 600 and the display module 300 are arranged in sequence, for example, along the length direction of the lock body 100. When the display module 300 is in the first position, the first direction mentioned above, for example, coincides with the length direction of the lock body 100, and the camera module 600 is electrically connected to the first circuit board 510 mentioned above, for example, through a third wire 550. During the rotation of the display module 300, since the position of the camera module 600 does not change, the connection between the third wire 550 and the camera module 600 and the first circuit board 510 is not easy to fail.
[0074] In other optional embodiments, a door is also provided in the embodiments of the present application, which includes a door body and the door lock mentioned above, and the door lock is arranged on the door body.
[0075] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
