Detailed implementation manners

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application usually described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0026] Accordingly, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0027] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

[0028] In the description of the present application, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings or the orientation or positional relationship in which the utility model product is usually placed during use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present application. In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0029] In addition, terms such as "horizontal" and "vertical" do not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0030] In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0031] In a pry-proof door lock in the related art, a switch assembly and an alarm component are usually provided. The switch assembly is used to be triggered when the door lock is pried, and the alarm component is used to emit voice prompt information or an alarm. For example, when pried, the switch assembly is triggered, and an electrical signal is transmitted to the alarm component, which can emit a warning message. Since the alarm component is provided, sound transmission holes are usually provided on the outer shell to release the sound emitted by the alarm component to the outside. However, the provision of the sound transmission holes causes the waterproof and moisture-proof performance of the pry-proof door lock to decline. Water vapor can enter the interior of the housing through the sound transmission holes, disturbing the electrical components in the switch assembly, resulting in a decline in the reliability of the switch assembly, and even possibly causing the pry-proof function to fail, bringing greater potential safety hazards.

[0032] For this reason, an embodiment of the present application provides a pry-proof switch, which uses the alarm component itself to block water vapor from disturbing the switch assembly and improves the reliability of the pry-proof function.

[0033] Figure 1 It is a schematic diagram of a pry-proof door lock in a first perspective in an embodiment of the present application; Figure 2 It is a schematic diagram of a pry-proof door lock in a second perspective in an embodiment of the present application. As Figure 1 and Figure 2 shown, the pry-proof door lock includes an inner lock 200 and an outer lock 100. When the pry-proof door lock is installed on a door body, the inner lock 200 is arranged on the side of the door body facing the indoor side, and the outer lock 100 is arranged on the side of the door body facing the outdoor side.

[0034] Figure 3 It is a partial cross-sectional view of the outer lock 100 in an embodiment of the present application; Figure 4 It is a partial exploded view of the outer lock 100 in an embodiment of the present application. As Figures 1 to 4 shown, the outer lock 100 includes a housing assembly and a pry-proof switch module arranged in the housing assembly. An adjacent installation cavity 115 and a sound generating cavity 116 are provided in the housing assembly. The pry-proof switch module includes a switch assembly 120 and an alarm component 130. The switch assembly 120 is arranged in the installation cavity 115. The installation cavity 115 and the sound generating cavity 116 are isolated by the alarm component 130. The sound generating cavity 116 is communicated with the outside of the housing assembly through a sound transmission hole 1161. The switch assembly 120 is used to be triggered when the pry-proof door lock is pried. The alarm component 130 is electrically connected to the switch assembly 120, and the alarm component 130 is used to emit an alarm sound when the switch assembly 120 is triggered.

[0035] It can be seen that in the embodiment of the present application, the installation cavity 115 and the sound generating cavity 116 are isolated by the alarm component 130. Although the sound generating cavity 116 is communicated with the outside of the pry-proof door lock through the sound transmission hole 1161, due to the isolation effect of the alarm component 130, water vapor cannot enter the installation cavity 115 through the alarm component 130. Therefore, it can be ensured that the switch assembly 120 in the installation cavity 115 is not disturbed by water vapor, thereby ensuring its reliability.

[0036] In the embodiment of the present application, the housing assembly includes a front mask 110, a sealing plate 150, and a back plate 170. Among them, the front mask 110 includes a front panel 111 and side plates 113 arranged around the edge of the front panel 111. The front mask 110 is an integral structure, and the front mask 110 is snapped together with the back plate 170. The front panel 111 and the sealing plate 150 are spaced apart in a first direction (the direction of arrow ab in the figure), and an installation cavity 115 and a sound - emitting cavity 116 are located between the front panel 111 and the sealing plate 150. The back plate 170 is stacked on the side of the sealing plate 150 facing away from the front panel 111. When the anti - pry door lock is installed on the door body, the back plate 170 is attached to the door body. A touch screen 112 can be provided on the front panel 111, and the touch screen 112 is used for the user to input a password to unlock the door.

[0037] In this embodiment, the installation cavity 115 and the sound - emitting cavity 116 are arranged between the sealing plate 150 and the front panel 111, and the sound - emitting cavity 116 is arranged on the side of the installation cavity 115 closer to the front panel 111 in the first direction. Since the alarm component 130 outputs the alarm sound through the sound - emitting cavity 116 and the sound - transmitting holes 1161, setting the sound - emitting cavity 116 at a position relatively close to the front panel 111 is more conducive to transmitting sound outward. A first avoidance hole 151 is opened on the sealing plate 150, and a part of the switch assembly 120 (specifically, the elastic rubber cap 122) passes through the first avoidance hole 151 and is used to abut against the door body. Correspondingly, a third avoidance hole 171 is provided on the back plate 170, and the third avoidance hole 171 is opposite to the first avoidance hole 151, so that a part of the switch assembly 120 can pass through the first avoidance hole 151 and the third avoidance hole 171 to extend out of the housing assembly, thereby abutting against the door body to enable the anti - pry function. When the switch assembly 120 loses contact with the door body, it will be triggered, and at this time, the alarm component 130 can emit an alarm sound.

[0038] In this embodiment, the sound - transmitting holes 1161 extend in a second direction (the direction of arrow ef in the figure), and the second direction is perpendicular to the first direction. It can be understood that the sound - transmitting holes 1161 pass through the side plates 113 in the second direction, so as to communicate with the outside. In the normal assembly state of the anti - pry door lock, the first direction is perpendicular to the door body, that is, the front - to - back direction; in this embodiment, the second direction is the vertical direction, perpendicular to the ground, that is, the sound - transmitting holes 1161 are arranged downward. The sound - transmitting holes 1161 penetrate out of the side plates 113 and face the ground, which can ensure the flatness of the front panel 111 and improve the aesthetics; at the same time, it can also reduce the risk of liquid flowing into the sound - emitting cavity 116 through the sound - transmitting holes 1161 to a certain extent. In other alternative embodiments, the sound - transmitting holes 1161 can also penetrate out of the side plates 113 in the left - to - right direction; or the sound - transmitting holes 1161 can also penetrate out of the front panel 111.

[0039] The number of sound transmission holes 1161 can be multiple. In this embodiment, the sound generating cavity 116 communicates with the outside through three sound transmission holes 1161, and the three sound transmission holes 1161 are arranged in parallel at intervals in the third direction (the direction of arrow cd in the figure). The third direction is perpendicular to the first direction and the second direction. When the anti-pry door lock is normally assembled on the door body, the third direction is the left-right direction.

[0040] In this embodiment, the alarm component 130 is a waterproof horn, and the vibration generating surface of the waterproof horn faces the sound generating cavity 116. By using the waterproof horn as the alarm component 130, the waterproof performance of the alarm component 130 itself can be improved, so that the alarm component 130 will not lose its alarm function when encountering water or water vapor. The vibration generating surface of the waterproof horn faces the sound generating cavity 116, which is not only beneficial to transmitting sound waves to the sound generating cavity 116 and improving the sound transmission efficiency, but also when there is condensation on the vibration generating surface of the alarm component 130, the vibration of the generating surface can atomize the surface condensation, which is beneficial to the volatilization of the condensation and the discharge from the sound generating cavity 116. This can reduce the humidity inside the anti-pry door lock and is beneficial to improving the reliability. Optionally, the alarm component 130 is bonded to the front mask 110 through a sealant to achieve a sealing effect.

[0041] Figure 5 Schematic diagram of removing the back plate 170 and the sealing plate 150 from the outer lock 100 in an embodiment of the present application; Figure 6 Schematic diagram of removing the back plate 170, the sealing plate 150 and the waterproof cover 160 from the outer lock 100 in an embodiment of the present application. As Figure 5 and Figure 6 shown, in this embodiment, the housing assembly further includes a support platform 114 and a waterproof cover 160. Specifically, the support platform 114 is arranged inside the front mask 110 and is an integral structure with the front panel 111 and the side panel 113. The support platform 114 surrounds the installation cavity 115. The waterproof cover 160 and the sealing plate 150 are stacked, and the edge of the waterproof cover 160 is hermetically connected to the support platform 114. The waterproof cover 160 is provided with a second avoidance hole 161 corresponding to the first avoidance hole 151.

[0042] It can be understood that in this embodiment, the installation cavity 115 is sealed by the alarm component 130 on the side close to the front panel 111; the installation cavity 115 is sealed by the waterproof cover 160 on the side close to the back plate 170.

[0043] Further, a glue groove 1142 is provided on the support platform 114, and a sealing glue is provided in the glue groove 1142. The support platform 114 is hermetically connected to the waterproof cover 160 through the sealing glue. In this embodiment, the glue groove 1142 forms an annular path that matches the edge of the waterproof cover 160. When assembling the waterproof cover 160, first pour the sealing glue into the glue groove 1142, and then press the waterproof cover 160 against the support platform 114. The edge of the waterproof cover 160 contacts the sealing glue, thereby achieving a sealed bond.

[0044] In this embodiment, a first screw hole is provided on the support platform 114, and the waterproof cover 160 is connected to the first screw hole on the support platform 114 through a first screw 162, thereby improving the stability of the waterproof cover 160. A second screw hole 1141 is also provided on the support platform 114, and the sealing plate 150 is connected to the second screw hole 1141 of the support platform 114 through a second screw. The sealing plate 150 can further press the waterproof cover 160, thereby improving the sealing performance. In this embodiment, the waterproof cover 160 is connected to the support platform 114 through four first screws 162, and the sealing plate 150 is connected to the support platform 114 through two second screws.

[0045] In the embodiment of the present application, the switch assembly 120 includes a switch member 121 and an elastic rubber cap 122. A switch rod 1211 that can elastically expand and contract along a first direction is provided on the switch member 121. The switch rod 1211 has an extended position and a retracted position. When the switch rod 1211 is in the extended position, the switch assembly 120 is triggered, and the elastic rubber cap 122 seals the first avoidance hole 151 and the second avoidance hole 161. One end of the elastic rubber cap 122 in the first direction abuts against the switch rod 1211, and the other end is used to abut against the door body. It can be understood that when the anti-pry door lock is normally installed on the door body, one end of the elastic rubber cap 122 abuts against the switch rod 1211, and the other end passes through the second avoidance hole 161 on the waterproof cover 160, the first avoidance hole 151 on the sealing plate 150, and the third avoidance hole 171 on the back plate 170 to abut against the door body. At this time, the switch rod 1211 is in the retracted position. When the anti-pry door lock is pried, the entire outer lock 100 moves away from the door body, and the switch rod 1211 can elastically extend outwards, pushing the elastic rubber cap 122 to deform and protrude outwards. At this time, the switch rod 1211 is in the extended position, and the switch assembly 120 is triggered.

[0046] Specifically, the elastic rubber cap 122 of this embodiment includes a contact portion 1221 and an elastic skirt 1222 circumferentially arranged around the contact portion 1221. The contact portion 1221 passes through the first avoidance hole 151 and the second avoidance hole 161 and is spaced from the inner walls of the first avoidance hole 151 and the second avoidance hole 161. The elastic skirt 1222 is clamped between the waterproof cover 160 and the sealing plate 150. In this embodiment, the contact portion 1221 also passes through the third avoidance hole 171 on the back plate 170 and is spaced from the inner wall of the third avoidance hole 171. Optionally, the contact portion 1221 is shaft-shaped, the first avoidance hole 151, the second avoidance hole 161, and the third avoidance hole 171 are circular holes, and the contact portion 1221 is coaxially arranged with the first avoidance hole 151, the second avoidance hole 161, and the third avoidance hole 171. The contact portion 1221 being spaced from the inner walls of the first avoidance hole 151, the second avoidance hole 161, and the third avoidance hole 171 can ensure the flexibility of the contact portion 1221 in the first direction.

[0047] In this embodiment, an assembly groove 163 is provided on the cover plate. The assembly groove 163 is arranged around the second avoidance hole 161. The shape and size of the assembly groove 163 are adapted to those of the elastic skirt 1222. The elastic skirt 1222 is embedded in the assembly groove 163, so that the elastic rubber cap 122 is not easily displaced in the radial direction and can maintain coaxiality with the first avoidance hole 151, the second avoidance hole 161, and the third avoidance hole 171.

[0048] The elastic rubber cap 122 can be an integrally formed part. Optionally, the elastic rubber cap 122 is made of silicone material or rubber material.

[0049] In this embodiment, the anti-pry switch module further includes a circuit board 140. The switch assembly 120 is arranged on one side of the circuit board 140, and the alarm component 130 is arranged on the other side of the circuit board 140 and is electrically connected to the switch assembly 120 through the circuit board 140. In this embodiment, the switch element 121 in the switch assembly 120 is fixedly connected to the circuit board 140 and is electrically connected to the circuit board 140, and the circuit board 140 provides support for the switch element 121. The alarm component 130 can be directly connected to the circuit board 140; or, the circuit board 140 is fixed to the housing assembly and is connected to the alarm component 130 through a circuit.

[0050] Furthermore, a power supply port 141 is provided on the circuit board 140, a power supply hole 1131 for exposing the power supply port 141 is provided on the shell assembly, and the shell assembly also includes a rubber plug 1132 for opening or closing the power supply hole 1131. The power supply port 141 can supply power to the anti-pry door lock to ensure the realization of corresponding functions (such as password unlocking, fingerprint unlocking). For example, after the battery installed in the anti-pry door lock fails, the anti-pry door lock can be powered by an external charging device through the power supply port 141. Optionally, the power supply port 141 is a Type-C port. In other embodiments, the power supply port 141 can also use other types of ports that can realize power input. By providing a rubber plug 1132 in the power supply hole 1131, it is possible to prevent water vapor from entering the anti-pry door lock from the power supply hole 1131 when the power supply port 141 is not in use, and intrude the circuit board 140 and the switch assembly 120.

[0051] In this embodiment, the power supply hole 1131 is opened on the side plate 113 and faces the second direction, and is arranged side by side with the sound transmission hole 1161 at intervals.

[0052] In summary, the pry-proof door lock provided in the embodiment of the present application includes a housing assembly and an anti-pry switch module disposed in the housing assembly, wherein the housing assembly is provided with an adjacent mounting cavity 115 and a sound-emitting cavity 116, and the anti-pry switch module includes a switch assembly 120 and an alarm component 130, wherein the switch assembly 120 is disposed in the mounting cavity 115, wherein the mounting cavity 115 is isolated from the sound-emitting cavity 116 by the alarm component 130, and the sound-emitting cavity 116 is connected to the outside of the housing assembly through the sound transmission hole 1161; the switch assembly 120 is used to be triggered when the pry-proof door lock is pried, and the alarm component 130 is electrically connected to the switch assembly 120, and the alarm component 130 is used to emit an alarm sound when the switch assembly 120 is triggered. In the embodiment of the present application, the alarm component 130 can isolate the mounting cavity 115 from the sound-emitting cavity 116, so that even if water vapor enters the sound-emitting cavity 116 through the sound transmission hole 1161, under the blocking effect of the alarm component 130, the water vapor cannot further enter the mounting cavity 115 to affect the function of the switch assembly 120. Therefore, the anti-theft door lock provided in the embodiment of the present application has good waterproof and moisture-proof performance and better reliability.
