[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0030] In the related art, whether it is an intelligent lock or other types of automatic locks, an electric motor is usually used to drive the opening and closing of the lock according to an electrical signal. At the same time, during the driving process of the electric motor, vibrations and noises will be generated, thus affecting the user experience.

[0031] To solve the above technical problems, the present application provides a lock and a door to improve the problems of large vibration amplitude and high noise during the driving process of the lock.

[0032] The following Figures 1 to 6 , describes the embodiments of the present application.

[0033] According to an embodiment of the present application, on the one hand, a lock is provided, as Figure 1As shown, it includes a lock housing 1, a rotary drive assembly 2, and a first elastic assembly 3. Specifically, the lock housing 1 can be a plastic housing or a metal housing. The rotary drive assembly 2 is a device such as a drive motor, and the first elastic assembly 3 is a spring piece. The rotary drive assembly 2 is installed in the lock housing 1 along a first direction 4 by screwing. One end of the first elastic assembly 3 is connected to the lock housing 1 by screwing or by snap - fitting in a card slot. The other end of the first elastic assembly 3 presses against the rotary drive assembly 2 along a second direction 5. The first elastic assembly 3 can be deformed and reset along the second direction 5. Among them, the first direction 4 and the second direction 5 are arranged at an angle.

[0034] It should be noted that the statement "the other end of the first elastic assembly 3 presses against the rotary drive assembly 2 along the second direction 5" means that the other end of the first elastic assembly 3 contacts the rotary drive assembly 2 with a certain pressure, and the magnitude of the pressure can be selected and set according to actual needs. The first direction 4 and the second direction 5 are shown in detail in Figure 1 as shown in.

[0035] It also should be noted that the rotary drive assembly 2 is installed in the lock housing 1 along the first direction 4, which means that the tightening direction of the connecting piece 9 at the connecting part 803 of the rotary drive assembly 2 and the lock housing 1 is the first direction 4, or the tightening direction of most of the connecting pieces 9 connecting the rotary drive assembly 2 and the lock housing 1. For example, if three screws are tightened along the direction perpendicular to the bottom of the lock housing 1 and one screw is tightened along the direction perpendicular to the side wall of the lock housing 1, then the first direction 4 is generally considered to be the direction perpendicular to the bottom of the lock housing 1.

[0036] Specifically, as Figure 1 shown, the first elastic assembly 3 can be fixedly connected to the inner bottom surface of the lock housing 1, or can be connected to the side wall surface of the lock housing 1, or can also be connected to other parts of the lock housing 1, as long as the first elastic assembly 3 can press against the rotary drive assembly 2 along the second direction 5. The lock can be an intelligent lock or other locks provided with a rotary motor.

[0037] It is worth noting that the first elastic assembly 3 can press against the side surface of the rotary drive assembly 2 along the first direction 4. Of course, it can also press against other parts of the rotary drive assembly 2. Preferably, the first elastic assembly 3 presses against the side surface of the rotary drive assembly 2 along the first direction 4. The included angle range between the first direction 4 and the second direction 5 is from 10° to 170°, specifically any one of 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, and 170°, etc. Preferably, the first direction 4 is perpendicular to the second direction 5, that is, 90°, which is the most commonly used state, facilitating the installation of the first elastic assembly 3 and having good vibration isolation and noise reduction effects.

[0038] In this embodiment, as Figure 1 shown, by fixedly arranging a first elastic component 3 inside the lock housing 1, the rotary drive component 2 is pressed, and the first elastic component 3 can elastically deform and reset along the second direction 5. Thus, the first elastic component 3 can apply a certain pressure to the rotary drive component 2, and through the elastic potential energy of the first elastic component 3, the amplitude of the rotary drive component 2 along the second direction 5 is reduced, and the vibration noise is reduced.

[0039] In one embodiment, as Figure 1 shown, the lock further includes a second elastic component (not shown in the drawings). One end of the second elastic component is connected to the lock housing 1 by means of screw connection or snap connection in a card slot. The other end of the second elastic component presses against the rotary drive component 2 along the third direction 6. The second elastic component can deform and reset along the third direction 6. Among them, the third direction 6 is arranged at an angle with both the first direction 4 and the second direction 5.

[0040] It should be noted that the statement "the other end of the second elastic component presses against the rotary drive component 2 along the third direction 6" means that the other end of the second elastic component contacts the rotary drive component 2 with a certain pressure, and the magnitude of the pressure can be selected and set according to actual needs; for details of the third direction 6, see Figure 1 as shown in

[0041] It is worth noting that the second elastic component can press against the side surface of the rotary drive component 2 along the first direction 4. Of course, it can also press against other parts of the rotary drive component 2. Preferably, the second elastic component presses against the side surface of the rotary drive component 2 along the first direction 4. The included angle range between the third direction 6 and the first direction 4 is 10° to 170°, specifically any one of 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, and 170°, etc.; the included angle range between the third direction 6 and the second direction 5 is 10° to 170°, specifically any one of 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, and 170°, etc.; preferably, the third direction 6 is perpendicular to the first direction 4, that is, 90°, and / or the third direction 6 is perpendicular to the second direction 5, that is, 90°. More preferably, the third direction 6 is perpendicular to both the first direction 4 and the second direction 5. This is the most commonly used state, which is convenient for the installation of the second elastic component and has a good vibration isolation and noise reduction effect.

[0042] In this embodiment, as Figure 1As shown, by providing a second elastic component within the lock housing 1 to press against the third direction 6 of the rotary drive component 2, and the second elastic component can elastically deform and reset along the third direction 6, so that the second elastic component can apply a certain pressure to the rotary drive component 2, reducing the amplitude of the rotary drive component 2 along the third direction 6 to further reduce vibration noise.

[0043] In one embodiment, as Figure 4 shown, a shock-absorbing and sound-absorbing component 7 is provided at the portion of the first elastic component 3 that contacts the rotary drive component 2; and / or, a shock-absorbing and sound-absorbing component 7 is provided at the portion of the second elastic component that contacts the rotary drive component 2; specifically, the shock-absorbing and sound-absorbing component 7 is an elastic foam, a compressible rubber block, or other perforated and compressible block; the shock-absorbing and sound-absorbing component 7 can be adhesively bonded to the first elastic component 3 with glue.

[0044] In this embodiment, as Figure 4 shown, the provision of the shock-absorbing and sound-absorbing component 7 can reduce the transmission of the vibration force of the rotary drive component 2 to the first elastic component 3 and the second elastic component, thereby reducing the vibration of the first elastic component 3 and the second elastic component and further reducing noise.

[0045] In one embodiment, as Figure 1 shown, the lock further includes a shock-absorbing pad 8, and the shock-absorbing pad 8 can be a pad with elastic deformation such as a rubber pad. As Figure 3 shown, a fixed ear 201 is provided on the rotary drive component 2, and there are multiple fixed ears 201. As Figure 2 shown, a fixed column portion 101 is provided within the lock housing 1, and there are multiple fixed column portions 101, and the fixed ears 201 and the fixed column portions 101 correspond one-to-one. A shock-absorbing pad 8 is provided between the fixed ears 201 and the fixed column portions 101 and is connected by a connecting member 9, and the connecting member 9 is specifically a screw.

[0046] In this embodiment, as Figure 1 shown, by providing a shock-absorbing pad 8 between the fixed ears 201 on the rotary drive component 2 and the fixed column portions 101 within the lock housing 1 and connecting them through the connecting member 9, using the elastic potential energy of the shock-absorbing pad 8, part of the vibration of the rotary drive component 2 along the first direction 4 can be filtered out, thereby reducing the transmission of vibration from the rotary drive component 2 to the lock housing 1 and further isolating vibration and reducing noise.

[0047] In one embodiment, as Figure 5 and Figure 6As shown, the seismic isolation pad 8 includes an upper ring portion 801, a connecting portion 803, and a lower ring portion 802. The upper ring portion 801 and the lower ring portion 802 are coaxially arranged at intervals and are connected by the connecting portion 803.

Specifically, both the upper ring portion 801 and the lower ring portion 802 are annular; the distance between the upper ring portion 801 and the lower ring portion 802 is equal to the thickness of the fixed ear portion 201.

[0048] In this embodiment, as Figure 5 and Figure 6 shown, by including the upper ring portion 801 and the lower ring portion 802 in the seismic isolation pad 8, which respectively contact the two end faces of the fixed ear portion 201, a seismic isolation structure can be formed between the fixed ear portion 201 and both the connecting member 9 and the fixed column portion 101, thereby further reducing the transmission of seismic force from the rotary drive assembly 2 to the lock housing 1 in the first direction 4.

[0049] In a specific embodiment, the connecting portion 803 is an arc surface, and the outer side surface of the fixed ear portion 201 that contacts the connecting portion 803 fits with the connecting portion 803. As Figure 6 shown, the axis of the arc surface coincides with the axis of the upper ring portion 801 and the axis of the lower ring portion 802; in this embodiment, the seismic isolation pad 8 can be set to be minimized, reducing the cost of the seismic isolation pad 8; further, a weight reduction groove 804 can be provided on the connecting portion 803 of the seismic isolation pad 8 to further reduce the cost.
