A second mounting plate 21 is provided on the side of the rear lock body 20 opposite to the front lock body 10, and a rear cover plate 22 is detachably provided on the second mounting plate 21.

[0038] In the smart lock 100 with replaceable cover plates in the embodiment of the utility model, the lock core cover 13 and the first mounting plate 14 located on the front of the smart lock 100 are detachably arranged, and the rear cover plate 22 located on the back of the smart lock 100 can also be detachably arranged on the second mounting plate 21, that is, the lock core cover 13 and the rear cover plate 22 are both detachable and replaceable, which is convenient for users to disassemble and replace to customize personalized features, so that the smart lock 100 meets the personalized needs of users when they need to customize the lock core cover 13 and / or the rear cover plate 22, improves the applicability of the smart lock 100, and at the same time improves user satisfaction.

[0039] For ease of description, the smart lock 100 will be referred to as the smart lock 100 with a replaceable cover.

[0040] In this embodiment, the front lock body 10 and the rear lock body 20 are respectively arranged on the front and back of the door body. Therefore, the facial information collection module 11 and the numeric keyboard module 12 are arranged on the front of the front lock body 10, so that residents and other people with access rights can enter passwords or facial information through the numeric keyboard module 12 or the facial information collection module 11 to unlock the smart lock 100. The facial information collection module 11 and the numeric keyboard module 12 can constitute an input panel, which can be understood as a panel for inputting information, such as digital password information, facial information, and sound information. If the control module and other structures are arranged in the rear lock body 20, the security of the smart lock 100 can be improved to prevent the smart lock 100 from being maliciously disassembled, modified, and invaded.

[0041] The numeric keypad module 12 may include common 10 numeric keys and doorbell keys to implement functions such as password input and doorbell reminder. The specific structure and other functions of the numeric keypad keys can refer to the structure and function of the numeric keypad in the relevant technology, and will not be described in detail here.

[0042] Exemplarily, the facial information acquisition module 11 may include a facial recognition camera, a fill light, an ambient light sensor, and a distance sensor, all of which are electrically connected to the control module. The above components are used to directly or assist in facial recognition acquisition.

[0043] Among them, the face recognition camera can be used to collect face data and transmit it to the control module for face recognition. Of course, the face recognition camera can also be used to shoot outdoor images.

[0044] The ambient light sensor can intervene in the ambient light in the environment where the door is located. Specifically, when the ambient light sensor detects that the current light is weak, in order to prevent the face recognition camera from failing to collect face data completely and clearly, the ambient light sensor can transmit a signal to the control module. The control module can control the fill light to turn on according to the signal to illuminate the face, thereby enabling the face recognition camera to collect face data more completely and clearly, thereby improving the unlocking success rate.

[0045] In one embodiment, the fill light may be an LED light that can emit white light.

[0046] The distance sensor can be used to detect whether a person is approaching. When a person approaches the door and is detected by the distance sensor, the distance sensor can send a signal to the control module, and the control module can control the face recognition camera to turn on. When the use is finished, the control module turns off the face recognition camera. In this way, when some people just pass by and the smart lock 100 does not need to be unlocked, the power consumption of the smart lock 100 can be reduced by turning off the face recognition camera.

[0047] Furthermore, a microphone for collecting and playing sounds can be arranged near the facial information collection module 11. The microphone is electrically connected to the control module. When the facial data of certain visitors is not stored in the control module, the resident can control the microphone to turn on so that the visitor can speak to the resident through the microphone to verify his / her identity. The resident can also actively turn on the microphone to communicate with the visitor, thereby improving the intelligence and diversified functions of the smart lock 100.

[0048] It is worth noting that the front lock body 10 and the rear lock body 20 in the present embodiment are both roughly rectangular. If the front lock body 10 is divided into an upper section and a lower section, and the rear lock body 20 is divided into an upper section and a lower section, then the relative upper section and the relative lower section of the front lock body 10 can be understood as the upper half and the lower half of the front lock body 10, that is, the lock core cover 13 is arranged in the lower half of the front lock body 10, and the relative upper section and the relative lower section of the rear lock body 20 can be understood as the upper half and the lower half of the rear lock body 20.

[0049] The key lock hole 15 is arranged in the front lock body 10 and corresponds to the lock core arranged in the door body. In a normal state, the lock core cover 13 covers the key lock hole 15. In an emergency situation where the lock cannot be unlocked by recognizing the face through the facial information collection module 11 and entering the password through the numeric keyboard module 12, the lock can be unlocked by removing the lock core cover 13 and inserting the key into the key lock hole 15 for mechanical unlocking.

[0050] In some embodiments, the detachable setting between the lock core cover 13 and the first mounting plate 14 can be a commonly used detachable manner such as snap-fitting, screwing, and gluing, which facilitates the disassembly, replacement, and reinstallation of the lock core cover 13 when necessary.

[0051] In some embodiments, the lock core cover 13 can be made of materials such as ceramic, metal, glass or acrylic (plastic).

[0052] It can be understood that the lock core cover 13 occupies a certain space on the front side of the front lock body 10. In order to display the structure outdoors, the lock core cover 13 is set to be detachable and replaceable, so that residents can customize different colors and patterns of the lock core cover 13. At the same time, residents can also purchase their favorite lock core cover 13 for replacement to adjust the different styles displayed by the smart lock 100 to meet the user's personalized needs.

[0053] In this embodiment, a plurality of installation spaces or a plurality of installation structures may be formed on the rear lock body 20 for installing the above-mentioned control module, power module and other structures, so as to realize the integrated installation of functional elements.

[0054] The control module is the control center and data processing center of the smart lock 100, which may include a controller, a memory and a communication module electrically connected to the controller. The controller may be a single chip microcomputer or other components with control and data processing functions, and the memory may store the facial data of people who can pass through. When the facial information acquisition module 11 acquires facial information, the controller may match the acquired facial information with the facial data stored in the memory. When the facial match is successful, the controller may control the smart lock 100 to open.

[0055] The communication module may be a WIFI module to realize the wireless connection function of the smart lock 100. For example, when the resident is not at home and the guest needs to enter the house, the resident can remotely unlock the door through the communication module to avoid the guest being impatient due to waiting for a long time.

[0056] In this embodiment, the power module can be a detachable and rechargeable lithium battery module. When the lithium battery module runs out of power, the resident can remove it for charging. The lithium battery has a strong endurance and a long service life, and can provide effective power support for the smart lock 100 to ensure the normal operation of the smart lock 100.

[0057] In one embodiment, a charging port electrically connected to the power module may also be provided on the rear lock body 20. When the power module is out of power, the power module may be directly charged through the charging port, eliminating the process of disassembling and installing the power module.

[0058] Furthermore, a power detection module can be provided in the control module and electrically connected to the power module to detect the real-time power of the power module. A display module electrically connected to the control module can also be provided on the rear lock body 20 to indicate the real-time power of the power module.

[0059] Exemplarily, the display module can be a structure with display function such as a display light and a display screen. The display light can display a green light or a red light to indicate whether the power module has power or not, respectively, and the display screen can display the power percentage to indicate the power status of the power module.

[0060] In addition, a voice prompt module electrically connected to the control module can be provided on the rear lock body 20. When the power module drops to a certain level, the voice prompt module can issue a voice prompt to remind the resident of the power status of the power module, reminding the resident to replace or charge it in time.

[0061] In this embodiment, the second mounting plate 21 can be understood as a recessed structure on the rear lock body 20 or a flat plate structure that can be used to mount related structures. To facilitate the stable installation of the rear cover plate 22, the second mounting plate 21 is a flat plate structure on the rear lock body 20, so that the rear cover plate 22 is also relatively flat and regular on the rear lock body 20.

[0062] In some embodiments, the detachable setting between the rear cover plate 22 and the second mounting plate 21 can be a commonly used detachable manner such as snap-fitting, screwing, gluing, etc., which facilitates the removal, replacement and reinstallation of the rear cover plate 22 when necessary.

[0063] In some embodiments, the rear cover 22 can be made of materials such as ceramic, metal, glass or acrylic (plastic).

[0064] It can be understood that the rear cover 22 occupies a certain space in the rear lock body 20. Therefore, by setting the rear cover 22 to be detachable and replaceable, the resident can customize different colors and patterns of the rear cover 22. At the same time, the resident can also purchase the rear cover 22 they like to replace it, so as to adjust the different styles displayed by the smart lock 100 to meet the user's personalized needs.

[0065] For more information, please combine Figure 4 A backup power module 20 a is also provided at the relatively lower section of the rear lock body 20 , and the backup power module 20 a is electrically connected to the control module, the numeric keyboard module 12 and the facial information collection module 11 .

[0066] The above-mentioned power module is the main power module. When the resident fails to replace the main power module in time, in order to avoid the problem that the smart lock 100 stops working due to the exhaustion of power in the main power module, this embodiment also provides a backup power module 20a in the rear lock body 20. When the main power module is exhausted, the backup power module 20a can continue to supply power to the smart lock 100 to ensure the subsequent use of the smart lock 100.

[0067] In an embodiment of the utility model, the backup power module 20a can be a dry battery module, which can control the cost of the smart lock 100 while meeting the needs of normal power supply and backup power supply, and also facilitate the replacement of the backup power module 20a.

[0068] Furthermore, a cat's eye screen 23 electrically connected to the control module is provided at the upper portion of the rear lock body 20. The position of the cat's eye screen 23 corresponds to the position of the power module, so that the cat's eye screen 23 is electrically connected to the power module. An unlocking button 24 electrically connected to the control unit is provided below the cat's eye screen 23. When a visitor is photographed by the facial information collection module 11 outdoors, the resident can check through the cat's eye screen 23. If it is confirmed that the visitor can enter, the resident can unlock the smart lock 100 by pressing the unlocking button 24.

[0069] In addition, a key lock hole corresponding to the lock core in the door body is also provided on the rear lock body 20, and the rear cover plate 22 covers the rear key lock hole. When the smart lock 100 is out of power or there is a problem with the indoor unlocking, the resident can remove the rear cover plate 22 and use a key or other tool to open the smart lock 100. Alternatively, a knob corresponding to the key lock hole can be provided on the rear cover plate 22, and the smart lock 100 can be unlocked by turning the knob.

[0070] See also Figure 3 and Figure 5 In one embodiment, a plurality of first engaging structures 141 are provided on the first mounting plate 14 along the length direction of the first mounting plate 14; a plurality of second engaging structures 1321 are provided on the surface of the lock core cover 13 facing the first mounting plate 14 along the length direction of the lock core cover 13; the plurality of first engaging structures 141 correspond one to one with the plurality of second engaging structures 1321, and the first engaging structures 141 can be slidably engaged with or slidably separated from the second engaging structures 1321.

[0071] Specifically, since the lock core cover 13 is long, the multiple first engaging structures 141 and the multiple second engaging structures 1321 are respectively distributed along the length direction of the first mounting plate 14 and the lock core cover 13, so that the lock core cover 13 can be engaged and fixed at multiple locations when installed on the first mounting plate 14, and the installation is relatively stable. The first engaging structure 141 and the second engaging structure 1321 are engaged or separated by sliding, and compared with the direct engaging method that needs to be pried to separate during disassembly, the sliding engaging method is easier to operate.

[0072] Exemplarily, the sliding engagement and sliding separation between the first engaging structure 141 and the second engaging structure 1321 can be that the second engaging structure 1321 is separated from the first engaging structure 141 when it is in a first position relative to the first engaging structure 141, and the lock core cover 13 drives the second engaging structure 1321 to slide to a second position relative to the first engaging structure 141 and is engaged and fixed with the first engaging structure 141, and the second engaging structure 1321 is separated from the first engaging structure 141 again when it slides from the second position back to the first position.

[0073] In addition, the lock core cover 13 in this embodiment includes a first cover plate 131 and a second cover plate 132 that are matched with each other. The second cover plate 132 is fitted to the first mounting plate 14 , and the surface of the first cover plate 131 is flush with the surface where the facial information acquisition module 11 is located.

[0074] Specifically, the surfaces facing each other of the first cover plate 131 and the second cover plate 132 are both planes, so that the two are tightly stacked, and the compactness of the lock core cover 13 is improved. The first cover plate 131 and the second cover plate 132 can be stacked together by gluing, screwing, or snapping. The second cover plate 132 is fitted with the first mounting plate 14, so that the lock core cover 13 is relatively flat and regular when installed on the first mounting plate 14, and the installation is more stable.

[0075] The detachable arrangement of the lock core cover 13 and the first mounting plate 14 can be understood as the detachable arrangement of the second cover plate 132 and the first mounting plate 14, the second engaging structure 1321 is arranged on the second cover plate 132, and the structure arranged on the lock core cover 13 hereinafter can be understood as being arranged on the second cover plate 132. The surface of the first cover plate 131 is flush with the surface of the surface where the facial information collection module 11 is located, making the front of the smart lock 100 more beautiful and regular, and improving the aesthetics of the smart lock 100.

[0076] Please continue reading Figure 3 and Figure 5 In one embodiment, the first engaging structure 141 is a first card block 141 provided on the first mounting plate 14, and the first card block 141 is formed by the first mounting plate 14 protruding toward the lock core cover 13 and then bending outward, and multiple first card blocks 141 are evenly distributed on both sides of the first mounting plate 14 and symmetrically arranged about the center line of the first mounting plate 14; the second engaging structure 1321 is a first card hole 1321 provided on the lock core cover 13, and multiple first card holes 1321 are evenly distributed on both sides of the lock core cover 13 and symmetrically arranged about the center line of the lock core cover 13.

[0078] The structure of the first clamping block 141 and the first clamping hole 1321 is relatively simple, and the clamping fit effect is better. Through the cooperation between the multiple first clamping structures 141 evenly distributed on the first mounting plate 14 and the second clamping structures 1321 evenly distributed on the lock core cover 13, the clamping positions between the first mounting plate 14 and the lock core cover 13 can be evenly distributed, the clamping fit between the first mounting plate 14 and the lock core cover 13 is more evenly stressed, and it is also easier to assemble and disassemble the lock core cover 13.

[0079] For example, the number of the first engaging structure 141 and the number of the second engaging structure 1321 can both be two, which can ensure the engaging and fixing effect of the first engaging structure 141 and the second engaging structure 1321 while controlling the structural complexity of the front panel and the lock core cover 13. Of course, in other embodiments, the number of the first engaging structure 141 and the second engaging structure 1321 can also be more or less, which can be set according to specific needs.

[0080] In this embodiment, the shape of the first clamping block 141 is adapted to the shape of the first clamping hole 1321. The first clamping hole 1321 may include a two-part structure, one part is for the first clamping block 141 to pass through, and the other part limits the first clamping block 141 from falling off and sliding out of the first clamping hole 1321. Therefore, the shape of the first clamping block 141 is adapted to the shape of the first clamping hole 1321. It can be understood that the shape of the bent part structure of the first clamping block 141 is adapted to the shape of the part of the first clamping hole 1321 that can be passed through by itself, and the shape of the extending part structure of the first clamping block 141 is adapted to the shape of the part of the first clamping hole 1321 that limits itself from falling off.

[0081] See also Figure 3 and Figure 5 In one embodiment, a first limiting protrusion 1411 is provided on the inner surface of the first clamping block 141 opposite to the lock core cover 13, and a second limiting protrusion 1322 is provided on the back side of the first clamping hole 1321 close to the edge of the lock core cover 13. When the first clamping block 141 is buckled with the first clamping hole 1321, the first limiting protrusion 1411 and the second limiting protrusion 1322 contact and limit.

[0082] Specifically, the first limiting protrusion 1411 is an arc-shaped structure with a smooth surface protruding from the inner surface of the first clamping block 141, and the second limiting protrusion 1322 is an arc-shaped structure with a smooth surface protruding from the inner surface of the lock core cover 13 (the above-mentioned second cover plate 132). In the process of the first clamping block 141 sliding to the second position relative to the first clamping hole 1321, the second limiting protrusion 1322 will slide over the surface of the first limiting protrusion 1411, so that the first limiting protrusion 1411 and the second limiting protrusion 1322 are in contact and limited, thereby improving the stability of the first engaging structure 141 and the second engaging structure 1321 when they are engaged.

[0083] See also Figure 3 and Figure 5 In one embodiment, a first fixing groove 142 is provided at the bottom of the first mounting plate 14, and a first elastic buckle 1323 is provided at the bottom of the lock core cover 13. The first elastic buckle 1323 is arranged to correspond to the first fixing groove 142, and the first elastic buckle 1323 is at least partially exposed at the bottom edge of the lock core cover 13.

[0084] Specifically, the first fixing groove 142 is formed by a surface depression at the bottom of the first mounting plate 14, and the first elastic buckle 1323 extends downward at the edge of the lock core cover 13. The first elastic buckle 1323 has a certain deformation ability. After the first elastic buckle 1323 is deformed and embedded in the first fixing groove 142, it can be elastically engaged and fixed with the first fixing groove 142, thereby further fixing the lock core cover 13 and the first mounting plate 14.

[0085] When the end of the first elastic buckle 1323 is pushed to deform the first elastic buckle 1323, the first elastic buckle 1323 can be disengaged from the first fixing groove 142 and separated from the first fixing groove 142. At this time, the first engaging structure 141 and the second engaging structure 1321 can be disassembled by moving the lock core cover 13 downward.

[0086] See also Figure 4 , Figure 6 and Figure 7 In one embodiment, a plurality of third engaging structures 2221 are provided on the surface of the rear cover plate 22 facing the second mounting plate 21 along the length direction of the rear cover plate 22; a plurality of fourth engaging structures 211 are provided on the second mounting plate 21 along the length direction of the second mounting plate 21; the plurality of third engaging structures 2221 correspond one-to-one to the plurality of fourth engaging structures 211, and the third engaging structures 2221 can be slidably engaged with or slidably separated from the fourth engaging structures 211.

[0087] Specifically, since the length of the rear cover plate 22 is relatively long, the plurality of third engaging structures 2221 and the plurality of fourth engaging structures 211 are respectively distributed along the length direction of the rear cover plate 22 and the second mounting plate 21, so that when the rear cover plate 22 is mounted on the second mounting plate 21, multiple parts can be engaged and fixed, and the installation is relatively stable. The third engaging structure 2221 and the fourth engaging structure 211 are engaged or separated by sliding, and compared with the direct engaging method that needs to be bent to be separated during disassembly, the sliding engaging method is easier to operate.

[0088] Exemplarily, the sliding engagement and sliding separation between the third engaging structure 2221 and the fourth engaging structure 211 can be that the fourth engaging structure 211 is separated from the third engaging structure 2221 when it is in a first position relative to the third engaging structure 2221, and the rear cover plate 22 drives the third engaging structure 2221 to slide to a second position relative to the fourth engaging structure 211 and is engaged and fixed with the third engaging structure 2221, and the fourth engaging structure 211 is separated from the third engaging structure 2221 again when it slides from the second position back to the first position.

[0089] In addition, the rear cover plate 22 in this embodiment includes a third cover plate 221 and a fourth cover plate 222 that are arranged in coordination with each other. The fourth cover plate 222 is arranged in close contact with the second mounting plate 21, and the surface of the third cover plate 221 is flush with the surface where the cat's eye screen 23 is located.

[0090] Specifically, the surfaces facing the third cover plate 221 and the fourth cover plate 222 are both planes, so that the two are tightly stacked, and the compactness of the rear cover plate 22 is improved. The third cover plate 221 and the fourth cover plate 222 can be stacked together by gluing, screwing, or snapping. The fourth cover plate 222 is fitted to the second mounting plate 21, so that the rear cover plate 22 is relatively flat and regular when installed on the second mounting plate 21, and the installation is more stable.

[0091] The detachable arrangement of the rear cover plate 22 and the second mounting plate 21 can be understood as the detachable arrangement of the fourth cover plate 222 and the second mounting plate 21, the third engaging structure 2221 is arranged on the fourth cover plate 222, and the structure arranged on the rear cover plate 22 hereinafter can be understood as being arranged on the fourth cover plate 222. The surface of the third cover plate 221 is flush with the surface of the cat's eye screen 23, making the back of the smart lock 100 more beautiful and regular, and improving the aesthetics of the smart lock 100.

[0092] See also Figure 4 , Figure 6 and Figure 7 In one embodiment, the third locking structure 2221 is a second locking block 2221 provided on the rear cover plate 22, and the second locking block 2221 is formed by the rear cover plate 22 protruding toward the second mounting plate 21 and then bending outward, and multiple second locking blocks 2221 are evenly distributed on both sides of the rear cover plate 22 and symmetrically arranged about the center line of the rear cover plate 22.

[0093] The fourth locking structure 211 includes a second locking hole 2111 provided on the second mounting plate 21 and a third locking block 2112 located on the back side of the second mounting plate 21 and corresponding to the second locking hole 2111. The third locking block 2112 is formed by the second mounting plate 21 protruding in a direction away from the rear cover plate 22 and then bending outward. The plurality of second locking holes 2111 are evenly distributed on both sides of the second mounting plate 21 and are symmetrically arranged about the center line of the second mounting plate 21.

[0094] In this embodiment, the second mounting plate 21 is roughly rectangular in shape, wherein the line is the symmetry line of the second mounting plate 21 extending along the length direction, and the rear cover plate 22 is also roughly rectangular in shape, wherein the line is the symmetry line of the rear cover plate 22 extending along the length direction.

[0095] The structure of the second clamping block 2221 and the second clamping hole 2111 is relatively simple, and the clamping effect is better. Through the cooperation between the multiple third clamping structures 2221 evenly distributed on the rear cover 22 and the fourth clamping structure 211 evenly distributed on the second mounting plate 21, the clamping positions between the rear cover 22 and the second mounting plate 21 can be evenly distributed, the clamping force between the rear cover 22 and the second mounting plate 21 is more uniform, and it is also easier to assemble and disassemble the rear cover 22.

[0096] Exemplarily, there may be three third engaging structures 2221 and three fourth engaging structures 211 , which can control the structural complexity of the rear lock body 20 and the rear cover plate 22 while ensuring the engaging and fixing effect of the third engaging structures 2221 and the fourth engaging structures 211 .

[0097] Of course, in other embodiments, the third engaging structures 2221 and the fourth engaging structures 211 may also be of greater or lesser numbers according to specific requirements.

[0098] In this embodiment, the shape of the second clamping block 2221 is adapted to the shape of the second clamping hole 2111, and the second clamping hole 2111 may include a two-part structure, one part is for the second clamping block 2221 to pass through, and the other part limits the second clamping block 2221 from falling off and sliding out of the second clamping hole 2111. Therefore, the shape of the second clamping block 2221 is adapted to the shape of the second clamping hole 2111. It can be understood that the shape of the bent part structure of the second clamping block 2221 is adapted to the shape of the part of the second clamping hole 2111 that can be passed through by itself, and the shape of the extending part structure of the second clamping block 2221 is adapted to the shape of the part of the second clamping hole 2111 that limits itself from falling off.

[0099] In addition, the third clamping block 2112 and the second clamping block 2221 have substantially the same structure. When the second clamping block 2221 passes through the clamping hole, the third clamping block 2112 can guide the movement of the second clamping block 2221. When the second clamping block 2221 moves along the second clamping hole 2111, the third clamping block 2112 can engage with the second mounting plate 21 at the edge of the second clamping hole 2111.

[0100] See also Figure 4 , Figure 6 and Figure 7 In one embodiment, a third limiting protrusion 22211 is provided on the inner surface of the second clamping block 2221 opposite to the second mounting plate 21, and a fourth limiting protrusion 212 is provided on the back side of the second clamping hole 2111 close to the edge of the second mounting plate 21. When the second clamping block 2221 is buckled with the second clamping hole 2111, the third limiting protrusion 22211 contacts and limits the fourth limiting protrusion 212.

[0101] Specifically, the third limiting protrusion 22211 is an arc-shaped structure with a smooth surface that protrudes from the inner surface of the second clamping block 2221, and the fourth limiting protrusion 212 is an arc-shaped structure with a smooth surface that protrudes from the inner surface of the rear cover 22 (i.e., the above-mentioned fourth cover 222). In the process of the second clamping block 2221 sliding to the second position relative to the second clamping hole 2111, the third limiting protrusion 22211 will slide over the surface of the fourth limiting protrusion 212, so that the third limiting protrusion 22211 and the fourth limiting protrusion 212 are in contact and limited, thereby improving the stability of the third engaging structure 2221 and the fourth engaging structure 211 when they are engaged.

[0102] See also Figure 4 , Figure 6 and Figure 7 In one embodiment, a limit step 213 is provided at the top of the second mounting plate 21 to abut against the top of the rear cover plate 22, and at least one alignment protrusion 214 is provided below the limit step 213 to be connected to the limit step 213 and extend along the length direction of the second mounting plate 21, and at least one alignment opening 2222 is provided at the top of the rear cover plate 22 to extend along the length direction of the rear cover plate 22, and the alignment protrusion 214 is correspondingly engaged with the alignment opening 2222.

[0103] Specifically, the limit step 213 is located at the top edge of the second mounting plate 21, and the alignment protrusion 214 is formed by the surface of the second mounting plate 21 protruding upward, which has a certain length and is inclined from the top to the bottom of the second mounting plate 21. The alignment port 2222 is formed by the inward opening of the top edge of the rear cover plate 22, and it also has a certain length. When the rear cover plate 22 is installed on the second mounting plate 21, after aligning the alignment port 2222 with the alignment protrusion 214, the rear cover plate 22 is pushed upward until the alignment port 2222 and the alignment protrusion 214 are fully engaged with each other, and the alignment protrusion 214 guides the rear cover plate 22 to the top of the second mounting plate 21 and abuts against the limit step 213. At this time, the rear cover plate 22 is fully fitted with the second mounting plate 21.

[0104] See also Figure 4 , Figure 6 and Figure 7 In one embodiment, there are two alignment protrusions 214 and two alignment openings 22224. The two alignment protrusions 214 are symmetrically arranged about the center line of the second mounting plate 21, and the two alignment openings 2222 are symmetrically arranged about the center line of the rear cover plate 22. The center line of the second mounting plate 21 is the symmetry line of the second mounting plate 21 extending along the length direction, and the center line of the rear cover plate 22 is the symmetry line of the rear cover plate 22 extending along the length direction.

[0105] The design of the two alignment protrusions 214 and the two alignment openings 2222 can ensure the stability of the rear cover plate 22 and the second mounting plate 21 when they are aligned on the basis of controlling the structural complexity of the second mounting plate 21 and the rear cover plate 22. In addition, the distribution of the two alignment protrusions 214 and the two alignment openings is relatively regular, which makes it easier to align the rear cover plate 22 on the second mounting plate 21.

[0106] In another embodiment, the number of the alignment protrusion 214 and the alignment opening 2222 can be one, which can simplify the structure of the second mounting plate 21 and the rear cover plate 22. In another embodiment, the number of the alignment protrusion 214 and the alignment opening 2222 can be three, four, or more, which can improve the stability of the rear cover plate 22 and the second mounting plate 21 during alignment installation.

[0107] See also Figure 4 , Figure 6 and Figure 7 In one embodiment, a second fixing groove 215 is provided at the bottom of the second mounting plate 21, and a second elastic buckle 2223 is provided at the bottom of the rear cover plate 22. The second elastic buckle 2223 is arranged to correspond to the second fixing groove 215. A depression is formed on the bottom edge of the second mounting plate 21 corresponding to the second fixing groove 215. The end of the second elastic buckle 2223 is placed on the depression and exposed at the bottom edge of the rear cover plate 22, and the thickness of the end of the elastic buckle is less than the depth of the depression.

[0108] Specifically, the second fixing groove 215 is formed by a surface depression at the bottom of the second mounting plate 21, and the second elastic buckle 2223 extends downward at the bottom edge of the rear cover plate 22. The second elastic buckle 2223 has a certain deformation ability, and after being deformed and embedded in the second fixing groove 215, it can be elastically engaged and fixed with the second fixing groove 215, thereby achieving the fixation between the rear cover plate 22 and the second mounting plate 21. When the end of the second elastic buckle 2223 is pushed to deform the second elastic buckle 2223, the second elastic buckle 2223 can be disengaged from the second fixing groove 215, and the rear cover plate 22 can be removed from the second mounting plate 21.

[0109] The end of the second elastic buckle 2223 is placed on the recess and its thickness is less than the depth of the recess, which can facilitate the user to use fingers or other objects to pull the end of the second elastic buckle 2223 out of the recess to the side of the rear cover plate 22. At this time, the second elastic buckle 2223 will be deformed and easily separated from the second fixing groove 215. The second elastic buckle 2223 can further drive the rear cover plate 22 to be separated from the second mounting plate 21 by a certain distance, and then the rear cover plate 22 can be moved downward to make the third clamping structure 2221 and the fourth clamping structure 211 staggered and separated, thereby realizing the disassembly of the rear cover plate 22.
