Detailed implementation manners

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually illustrative only and in no way constitutes a limitation on the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] As Figures 1 to 10 shown, an embodiment of the present invention provides a doorbell device, including a doorbell main body 100, a mounting bracket 200, and a disassembly and assembly module 300. The back surface of the doorbell main body 100 has a first connection structure 101 and a limiting member 102; the mounting bracket 200 has a second connection structure 201, and the first connection structure 101 and the second connection structure 201 are detachably connected; the disassembly and assembly module 300 is installed on the mounting bracket 200. The disassembly and assembly module 300 includes a sliding member 310 and a locking member 320. The sliding member 310 is arranged to be movable back and forth to stop or avoid the limiting member 102. The locking member 320 is made of a shape memory material, and the locking member 320 can be switched to a contracted state or an extended state under temperature change; wherein, when the locking member 320 is in the extended state, the locking member 320 prevents the sliding member 310 from moving, and the sliding member 310 prevents the limiting member 102 from moving, so as to prevent the separation of the first connection structure 101 and the second connection structure 201, thereby preventing the separation of the doorbell main body 100 and the mounting bracket 200; when the locking member 320 is in the contracted state, the locking member 320 avoids the sliding member 310, the sliding member 310 can slide to a position where it avoids the limiting member 102, and the first connection structure 101 can be separated from the second connection structure 201. Among them, the mounting bracket 200 can be fixed to a door or a wall, or fixed to other structural members.

[0046] In this solution, the doorbell body 100 and the mounting bracket 200 are connected by connecting the first connecting structure 101 and the second connecting structure 201, and the first connecting structure 101 and the second connecting structure 201 are prevented from separating by limiting the position of the limiting member 102 by the sliding member 310. When disassembling, the sliding member 310 needs to be moved to a position to avoid the limiting member 102 before disassembly can be performed, so that the sliding member 310 has an anti-theft effect; further, since the locking member 320 made of shape memory material is provided in this solution, when the locking member 320 is in an extended state, the movement of the sliding member 310 is prevented, so that even if there is a disassembly tool, the disassembly operation cannot be performed, and a specific temperature condition is required to shrink the locking member 320 before the disassembly operation can be performed, thereby further enhancing the anti-theft effect. Therefore, through this solution, the anti-theft performance of the existing doorbell device is improved, and the safety is improved.

[0047] The locking member 320 is made of memory plastic, and the temperature of the doorbell device in the working state is greater than the temperature in the non-working state. The locking member 320 is in an extended state when the doorbell device is in the working state, and in a contracted state when the doorbell device is in the non-working state.

[0048] The locking member 320 is combined with the actual use of the doorbell device. The doorbell device is installed before use. When in use, each electrical module will release heat after being powered on, and the doorbell device as a whole will heat up compared to when not in use. The temperature of the locking member 320 rises to a temperature at which elongation and deformation occur. In this way, the locking member 320 is in an elongated state, which prevents the movement of the sliding member 310, so that the doorbell device cannot be disassembled, thereby preventing damage by others. When normal disassembly is required, the doorbell device is powered off, and the temperature of the doorbell device drops to room temperature. The locking member 320 switches to a retracted state, and the locking member 320 does not hinder the movement of the sliding member 310, so that it can be disassembled by moving the sliding member 310.

[0049] like Figure 3 and Figure 4 As shown, the disassembly and assembly module 300 also includes a cover plate 330, which is connected to the mounting bracket 200, and the sliding member 310 includes a large slider 311 and a small slider 312 that are connected to each other, the large slider 311 is located in a cavity between the cover plate 330 and the mounting bracket 200, and at least a portion of the small slider 312 is exposed outside the cover plate 330, and the small slider 312 is used to stop or avoid the limit member 102; the locking member 320 is arranged on the cover plate 330 or the mounting bracket 200, and the locking member 320 is used to stop or avoid the large slider 311.

[0050] The cover plate 330 can limit the sliding member 310, and the opening on the cover plate 330 corresponds to the small slider 312, so that the small slider 312 will not interfere with the cover plate 330 when moving. The small slider 312 extending from the cover plate 330 can also be in limiting cooperation with the limiting member 102. Further, the mounting bracket 200 has a guide groove, and the large slider 311 is located in the guide groove. Under the limitation and guiding action of the guide groove, the large slider 311 moves back and forth along the guide groove.

[0051] Further, the disassembly and assembly module 300 further includes an elastic member 340 and a pushing block 350. The elastic member 340 applies an elastic force to the sliding member 310 to move the sliding member 310 and keep it in the position of the stop limiting member 102. The pushing block 350 pushes the sliding member 310 under the action of an external force, so that the sliding member 310 moves to a position avoiding the limiting member 102 against the elastic force of the elastic member 340. In this way, through the cooperation of the elastic member 340 and the pushing block 350, the reciprocating movement of the sliding member 310 is realized. After assembly, the disassembly and assembly module 300 is located between the doorbell main body 100 and the mounting bracket 200, and the doorbell main body 100 and the mounting bracket 200 are in contact, and the disassembly and assembly module 300 is not exposed, achieving an anti-disassembly effect.

[0052] Specifically, the moving direction of the pushing block 350 is perpendicular to the moving direction of the sliding member 310. The sliding member 310 has a pushing inclined surface 313, and the pushing inclined surface 313 is inclined with respect to both the moving direction of the pushing block 350 and the moving direction of the sliding member 310, and the pushing inclined surface 313 abuts against the pushing block 350; the mounting bracket 200 has a jack corresponding to the pushing block 350, and the pin outside the mounting bracket 200 can penetrate into the jack and push the pushing block 350 to move.

[0053] When it is necessary to disassemble the doorbell main body 100, the pin is inserted into the jack from the outside and the pushing block 350 is pushed to move. The pushing block 350 pushes the sliding member 310 to move through the pushing inclined surface 313, and the sliding member 310 moves to a position avoiding the limiting member 102 against the elastic force of the elastic member 340. Then the first connection structure 101 in the doorbell main body 100 can be separated from the second connection structure 201 in the mounting bracket 200, realizing the disassembly of the doorbell main body 100.

[0054] Such as Figure 4 and Figure 5As shown, the sliding member 310 has a first inclined surface 314 and a first stop surface 315, and the limiting member 102 has a second inclined surface 1021 and a second stop surface 1022, wherein, during the connection process of the first connecting structure 101 and the second connecting structure 201, the second inclined surface 1021 pushes the first inclined surface 314 to move the sliding member 310 to a position to avoid the limiting member 102; after the first connecting structure 101 and the second connecting structure 201 are connected, the elastic member 340 pushes the sliding member 310 to move to a position to stop the limiting member 102, and the first stop surface 315 and the second stop surface 1022 are stopped and matched.

[0055] Through the above arrangement, when the first connecting structure 101 and the second connecting structure 201 are approaching each other, after the second inclined surface 1021 contacts the first inclined surface 314, the second inclined surface 1021 pushes the first inclined surface 314 to move the sliding member 310 to a position avoiding the limiting member 102. The sliding member 310 and the limiting member 102 will not interfere with each other, and the limiting member 102 moves with the doorbell body 100. After the first connecting structure 101 and the second connecting structure 201 are connected, the elastic member 340 pushes the sliding member 310 to a position stopping the limiting member 102, and the first stop surface 315 and the second stop surface 1022 cooperate with each other to achieve the limitation of the limiting member 102, so that the doorbell body 100 cannot be separated from the mounting bracket 200.

[0056] Furthermore, if Figure 2 , Figure 5 and Figure 6 As shown, the side of the doorbell body 100 has a mounting groove 103 and a card cover 104, the mounting groove 103 corresponds to the card insertion position inside the doorbell body 100, and the card cover 104 includes a cover body 1041 and a buckle 1042 that are connected to each other, the cover body 1041 is used to open and close the mounting groove 103, and the buckle 1042 is used to drive the cover body 1041 to move, and the buckle 1042 is located on the back of the doorbell body 100; wherein, when the doorbell body 100 and the mounting bracket 200 are connected, the mounting bracket 200 covers the buckle 1042.

[0057] After the installation slot 103 is opened, the SD card can be inserted or removed at this position. Through the above arrangement, when the doorbell body 100 and the installation bracket 200 are connected, the installation bracket 200 covers the buckle 1042, so that the cover 1041 covering the installation slot 103 cannot be removed from the outside, thereby achieving anti-theft and ensuring user safety. When the doorbell body 100 is removed from the installation bracket 200, the buckle 1042 is exposed from the back of the doorbell body 100, and the card cover 104 can be opened.

[0058] Specifically, the inside of the card cover 104 is made of silica gel, which provides a waterproof effect after compression installation. The outside of the card cover 104 is made of plastic, maintaining the same appearance as the doorbell main body. There is an installation position for the USB silica gel plug on the back of the doorbell main body 100, compatible with the requirements of TYPE-C charging.

[0059] As Figure 3 and Figure 5 shown, the first connection structure 101 is a limiting groove, and the second connection structure 201 is a hook; both the limiting groove and the hook are multiple, and the multiple limiting grooves and the multiple hooks are arranged in one-to-one correspondence. In this way, the connection between the first connection structure 101 and the second connection structure 201 is realized by means of snap connection, which is convenient for disassembly and assembly.

[0060] As Figure 2 shown, the doorbell main body 100 includes a front shell assembly 110, a movement assembly 120, and a rear shell assembly 130. The front shell assembly 110 and the rear shell assembly 130 are detachably connected. The movement assembly 120 is located in the cavity between the front shell assembly 110 and the rear shell assembly 130. The first connection structure 101 and the limiting member 102 are located on the rear shell assembly 130.

[0061] Specifically, the front shell assembly 110 and the rear shell assembly 130 are connected by screws, and rubber plugs are installed at the connection hole positions to achieve the effects of sealing and aesthetics. The peripheries of the front shell assembly 110 and the rear shell assembly 130 correspond and are hermetically fitted, thus playing a waterproof role for the structural parts in the cavity between the front shell assembly 110 and the rear shell assembly 130.

[0062] As Figure 6 shown, the rear shell assembly 130 includes a rear shell main body 131, a heat dissipation sheet metal 132, and a heat dissipation plate. The heat dissipation sheet metal 132 is installed inside the rear shell main body 131, and the heat dissipation sheet metal 132 is in thermal conduction cooperation with the movement assembly 120. The heat dissipation plate is installed on the inner surface of the rear shell main body 131, and the heat dissipation plate is in thermal conduction cooperation with the heat dissipation sheet metal 132.

[0063] Through the above settings, the heat generated by the movement assembly 120 during operation can be sequentially conducted to the heat dissipation sheet metal 132, the heat dissipation plate, and the rear shell main body 131, and then dissipated to the outside through the rear shell main body 131. In this way, a good heat dissipation effect can be achieved, avoiding overheating of the movement assembly 120 and affecting normal operation.

[0064] Further, the heat dissipation sheet metal 132 has a plurality of convex hulls 1321 protruding towards the movement component 120. The plurality of convex hulls 1321 respectively correspond to different heat-generating components in the movement component 120. A heat-conducting pad 133 is attached to the convex hull 1321, and the heat-conducting pad 133 is in contact with the corresponding heat-generating component. A heat-conducting gel is filled between the heat dissipation plate and the heat dissipation sheet metal 132. Through the above settings, sufficient contact can be achieved between the various structures, thereby improving the heat conduction and heat dissipation effects. Specifically, the heat dissipation plate can be made of materials with good heat conduction effects such as aluminum foil and copper foil.

[0065] As Figure 7 shown, the front shell assembly 110 includes a front shell main body 111 and a heat dissipation metal sheet 112. The heat dissipation metal sheet 112 is disposed between the front shell main body 111 and the movement component 120, and the heat dissipation metal sheet 112 and the movement component 120 are in heat-conducting cooperation. The heat dissipation metal sheet 112 can dissipate heat from the movement component 120 to avoid local heat concentration affecting normal operation.

[0066] Specifically, the heat dissipation metal sheet 112 is connected to the front shell main body 111 through connecting columns. The movement component 120 includes a circuit board structure and a lens module 1232 and a fill light 1241 disposed on the circuit board structure. Among them, the heat dissipation metal sheet 112 and the fill light 1241 are in heat-conducting cooperation, and / or the heat dissipation metal sheet 112 and the circuit board structure are in heat-conducting cooperation.

[0067] Among them, the fill light 1241 is used to fill light for the lens module 1232. The fill light 1241 can specifically adopt an infrared fill light. The fill light 1241 generates a relatively high amount of heat during operation, and the heat dissipation metal sheet 112 can disperse the heat of the fill light 1241.

[0068] As Figure 2 、 Figure 8 and Figure 9 shown, the movement component 120 includes a main circuit board 121 and a button circuit board 122. The lower part of the main circuit board 121 and the upper part of the button circuit board 122 are connected by a pin header and a socket. A plurality of functional modules are distributed on both the main circuit board 121 and the button circuit board 122. In this solution, connecting the lower part of the main circuit board 121 and the upper part of the button circuit board 122 by a pin header and a socket can reduce the use of wires and improve the convenience of assembly.

[0069] Among them, the button circuit board 122 is closer to the front shell assembly 110 than the main circuit board 121. Among them, the multiple functional modules distributed on the main circuit board 121 include: an antenna module 1231 and a lens module 1232 disposed on one side of the main circuit board 121 facing the front shell assembly 110. Among them, the antenna module 1231 is located above the lens module 1232, and the lens module 1232 is located above the button circuit board 122; a WIFI module 1233, a main control chip 1234, a digital signal processing module 1235, and a grounding elastic sheet 1236 are disposed on one side of the main circuit board 121 facing the rear shell assembly 130. Among them, the WIFI module 1233 is located in the upper part of the main circuit board 121, and the main control chip 1234 and the digital signal processing module 1235 are located in the lower part of the main circuit board 121, so as to reduce signal interference.

[0070] The multiple functional modules distributed on the button circuit board 122 include: a fill light 1241, a microphone 1242, a button switch 1243, and multiple uniform light lamps 1244 disposed on one side of the button circuit board 122 facing the front shell assembly 110. Among them, both the fill light 1241 and the microphone 1242 are disposed in the upper part of the button circuit board 122. The fill light 1241 provides supplementary light for the lens module 1232. The button switch 1243 is disposed in the lower part of the button circuit board 122, and the multiple uniform light lamps 1244 are arranged around the button switch 1243; a socket, an indicator light 1245, and a power connection elastic sheet 1246 are disposed on one side of the button circuit board 122 facing the rear shell assembly 130. Among them, the indicator light 1245 is located in the lower part of the button circuit board 122.

[0071] Through the above settings, the multiple functional modules are reasonably arranged. Compared with conventional products, the integration degree is high and the number of circuit boards is small. The internal cable operations such as the sheet metal ground wire, the indicator light ground wire, and the connecting wire of the digital signal processing module 1235 are omitted, so that there is only one internal wire connection between the speaker and the button board in the relatively high-utilization structural space, greatly reducing the production line assembly man-hours and improving the operability and easy assembly of the production line.

[0072] As Figure 7 shown, the front shell assembly 110 includes a front shell main body 111, a window glass 113, a button cap 114, and a speaker 115 which are arranged on the front shell main body 111 from top to bottom. The front shell assembly 110 further includes a light shielding ring 116 and a button silicone sleeve 117. The light shielding ring 116 is snap-fitted to the front shell main body 111 and corresponds to the window glass 113. The button silicone sleeve 117 is installed on the front shell main body 111 and fits with the button cap 114. The above settings are structurally compact and can achieve the effects of waterproofing and dustproofing.

[0073] As Figure 6As shown in the figure, the rear shell assembly 130 includes a rear shell body 131, a silica gel plug 134 and a light guide column 135. The rear shell body 131 has an installation port and a light guide groove 1311. The silica gel plug 134 is detachably installed in the installation port. The light guide groove 1311 is located at the lower part of the rear shell body 131. The lower end of the light guide groove 1311 has an opening communicating with the outside. The light guide column 135 is arranged in the light guide groove 1311. The upper end of the light guide column 135 corresponds to the indicator light 1245 in the movement assembly 120. The rear shell body 131 is connected to the front shell assembly 110 through fasteners, and a sealing ring 105 is arranged between the rear shell body 131 and the front shell assembly 110. The light guide groove 1311 positions the light guide column 135, and the light guide column 135 conducts the light generated by the indicator light 1245 to the outside of the lower end of the rear shell body 131, playing a role in prompting working or lighting.

[0074] Further, as Figure 10 shown in the figure, the doorbell device includes two mounting brackets 200. The doorbell main body 100 can be selectively connected to any one of the mounting brackets 200. A sunshade 202 is arranged at the top of one of the mounting brackets 200. The sunshade 202 is located above the doorbell main body 100. There is no sunshade 202 at the top of the other mounting bracket 200; and / or, the doorbell device further includes a first adjusting bracket 410. The mounting bracket 200 can be selectively connected to the first adjusting bracket 410. The first adjusting bracket 410 has a positioning post 411 and a buckle 412. The positioning post 411 is used for inserting into the positioning hole 203 on the mounting bracket 200, and the buckle 412 is used for clamping with the card slot 204 on the mounting bracket 200. The first adjusting bracket 410 is used for adjusting the angle of the doorbell main body 100 in the left-right direction; and / or, the doorbell device further includes a second adjusting bracket 420. The mounting bracket 200 can be selectively connected to the second adjusting bracket 420. The second adjusting bracket 420 has a positioning post 411 and a buckle 412. The positioning post 411 is used for inserting into the positioning hole 203 on the mounting bracket 200, and the buckle 412 is used for clamping with the card slot 204 on the mounting bracket 200. The second adjusting bracket 420 is used for adjusting the angle of the doorbell main body 100 in the up-down direction.

[0075] Through the above settings, when installing the doorbell device, a suitable bracket can be selected according to the installation environment or usage requirements, so as to install the doorbell main body 100 at a suitable position and angle, thus meeting the needs of different users and improving the applicable range.

[0076] The above technical solutions of the present application mainly have the following characteristics and effects:

[0077] The three-level assembly of doorbell body + mounting bracket + first adjustment bracket or second adjustment bracket is adopted, and the temperature rise self-locking structure of memory plastic material is combined to ensure the consistency of appearance, and at the same time realize the prevention of doorbell body and card cover from bare-hand disassembly. The hidden seamless pressing card cover is realized without screw locking, and the temperature rise self-locking structure is combined to realize the anti-disassembly of the doorbell body, which greatly improves the anti-theft effect and customer experience of the doorbell.

[0078] The heat dissipation sheet metal's own convex bump is in contact with high-power consumption devices through a thermal pad, the front shell body reserves space for heat dissipation metal sheets, the heat dissipation sheet metal and the rear shell body reserve space for thermal gel coating, and the upper part of the rear shell body reserves a large space for aluminum foil attachment, realizing a multiple heat dissipation structure design. This allows the effective space under the full plastic shell to be used for large-area heat dissipation through multiple heat dissipation paths, meeting the self-locking requirements of the locking parts while effectively dissipating heat at an even temperature.

[0079] The design of integrating multiple functional devices with two circuit boards and making full use of the structural space ensures that the functions of each device are not interfered with and that the normal performance is achieved. The functions that can only be achieved with more than three circuit boards are integrated, that is, the product functions in multiple aspects such as visual, audible, and tactile. The product structure is small in size, and multiple functions of doorbell products are integrated under the premise of realizing a miniaturized style. It also has a high utilization rate of structural space and is characterized by high integration.

[0080] The design of distributed contact between sheet metal convex hull and grounding spring is adopted, combined with the reasonable arrangement of digital signal processing module, indicator light, microphone, etc., compared with conventional products, internal cables such as sheet metal grounding wire and indicator light grounding wire are omitted. As a result, there is only one internal wire connecting the speaker and the keypad in the structural space with high utilization rate, which greatly reduces the assembly time of the production line, greatly improves the operability and ease of assembly of the production line, and reduces the cost.

For those skilled in the art, the present invention may be modified and varied in various ways.
