[0032] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as limiting the present application.

[0033] Please refer to Figure 1 , the present application provides a door lock device 10, which is applied to an elevator 100. The elevator 100 includes a landing door 20 and a sill 30. A groove 21 is provided below the landing door 20. The door lock device 10 includes a retractable module 11. The retractable module 11 is disposed at the sill corresponding to the groove 21. The retractable module 11 can extend into the groove 21 to lock the landing door 20, and retract from the groove 21 into the sill 30 to unlock the landing door 20.

[0034] Specifically, the retractable module 11 can be a protrusion as shown in Figure 1 . The height of the protrusion is adapted to the groove 21. When the protrusion extends into the groove 21, the landing door 20 can be locked more securely. When a user pushes the landing door 20 outside the landing, the resistance of the protrusion can further protect the landing door 20.

[0035] In this way, the present application provides a door lock device 10 with a retractable module 11 below the landing door 20. When the retractable module 11 extends into the groove 21 on the landing door 20, it can lock and protect the landing door 20 at the same time, effectively preventing the situation that the landing door 20 of the elevator 100 is impacted by abnormal external force and causes the landing door 20 to disengage, resulting in an elevator fall accident.

[0036] Please refer to Figure 2 , in some embodiments, the door lock device 10 may further include a control module 12. The control module 12 is electrically connected to the retractable module 11. The control module 12 is configured to receive an unlocking signal to control the retractable module 11 to retract from the groove 21 into the sill 30, and to receive a locking signal to control the retractable module 11 to extend from the sill 30 into the groove 21.

[0037] Specifically, the unlocking signal can be an electrical signal indicating that the elevator has reached the destination floor, or a call signal when the user presses the up or down button on the external call device of the elevator, or a safety detection signal issued in the safety detection mode, which is not limited herein.

[0038] The locking signal can be a signal indicating that the elevator has left the current floor, or a safety detection signal issued in the safety detection mode, which is not limited herein.

[0039] The door lock device 10 of the present application can control the telescopic movement of the telescopic module 11 through the control module 12, so that the telescopic module 11 can lock or unlock the landing door 20 simultaneously.

[0040] Refer to Figure 3 、 Figure 4 and Figure 5 , the control module 12 includes a main board 121, a leveling detection unit 122, a first relay 123, an external call board 124, a second relay 125 and a control member 126. The main board 121 is electrically connected to the leveling detection unit 122 and the external call board 124 respectively. A motor 111 is provided in the telescopic module 11, and the motor 111 is connected in series with the external call board 124 through the first relay 123 and the second relay 125 to form a loop. The control member 126 is elastically or magnetically connected to the telescopic module 11. Among them, the first relay 123 can be Figure 3 、 Figure 4 or Figure 5 the SM relay in Figure 4 or Figure 5 the SJ relay in

[0041] When the main board 121 does not receive the leveling signal issued by the leveling detection unit 122, the first relay 123 is disconnected; after the main board 121 receives the leveling signal issued by the leveling detection unit 122, the first relay 123 is triggered to close.

[0042] When the external call board 124 does not receive the call signal, the second relay 125 is disconnected; after the external call board 124 receives the call signal, the second relay 125 is triggered to close. When both the first relay 123 and the second relay 125 are closed, the motor 111 is electrically connected to the external call board 124 to cause the motor 111 to start working, and the motor 111 drives the telescopic module 11 to retract into the sill.

[0043] Such as Figure 3 and Figure 5As shown, the retractable module 11 can be provided with two contacts that come into contact with the extended-in-place contact and the retracted-in-place contact to establish electrical connection. When the retractable module 11 is retracted into the sill and the retracted position is in place, the two contacts of the retractable module 11 come into contact and connect with the two retracted-in-place contacts on its two sides. At this time, the SR relay electrically connected to the retractable module 11 can be triggered to close, enabling the retractable module 11 to form an electrical circuit loop P1 through potential 3 and potential 4 of the landing call board 124. Among them, the SR relay can also be an electromagnetic relay.

[0044] Understandably, as Figure 3 shown, since the car control board, i.e., the car top board, is electrically connected to the main board 121 through the SR relay, and the main board 121 is electrically connected to the landing doors and car doors of the elevator. After the SR relay closes, the car top board can send an opening signal to the main board 121. Thus, the opening signal sent by the car top board can be transmitted to the main board 121 along with the closing of the SR relay. After receiving the opening signal, the main board 121 will control the landing doors and car doors of the elevator to open synchronously.

[0045] Please refer to Figure 3 and Figure 4 As Figure 3 shown, after the main board 121 receives the leveling signal from the leveling detection unit 122, it triggers the first relay 123, i.e., the SM relay, to close. When someone presses the landing call board 124 on the current floor to send a landing call signal, Figure 4 the second relay 125, i.e., the SJ relay, in closes, thereby controlling the motor 111 to start and driving the retractable module 11 outside the motor 111 to retract into the sill. That is to say, the starting condition of the motor 111 is jointly determined by the leveling signal and the landing call signal.

[0046] When the first relay 123 and / or the second relay 125 is / are disconnected, the motor 111 is powered off, and the retractable module 11 extends into the groove 21 from the sill under the elastic force or suction force of the control member 126. The disconnection of either the first relay 123 or the second relay 125 or the simultaneous disconnection of both relays will cause the motor 111 to lose power, so that the retractable module 11 is no longer driven by the motor 111 and can extend into the groove 21 under the elastic force or magnetic repulsive force of the control member 126.

[0047] When the motor 111 of the present application starts, it drives the retractable module 11 to contract, and when the motor 111 is powered off, it drives the retractable module 11 to protrude.

[0048] Among them, the control member 126 can be a spring or a magnet, which is not limited herein. When the control member 126 is a spring, one end of the spring is fixedly connected to the bottom surface of the retractable module 11, and the other end of the spring can be fixed at a position below the retracted position contact point of the retractable module 11. When the retractable module 11 retracts into the sill, the spring is compressed and deformed by the force. When the spring restores its shape and releases the elastic force, the retractable module 11 can be raised by the action of the elastic restoring force, so as to extend into the groove 21.

[0049] When the control member 126 is a magnet, a magnet A can be installed at the bottom of the retractable module 11, and another magnet B that repels magnet A can be fixed at a position below the retracted position contact point of the retractable module 11. When the retractable module 11 retracts into the sill, the distance between magnet A and magnet B is relatively close. The retractable module 11 can be raised from the sill by the magnetic repulsive force between magnet A and magnet B, so as to extend into the groove 21.

[0050] Please refer to Figure 6 , this application provides a safety detection device 40 for detecting the door lock device 10 described above. The safety detection device 40 includes a detection module 41 and a prompt module 42. The detection module 41 is electrically connected to the door lock device 10, and the detection module 41 is used to detect whether the telescopic position of the retractable module 11 is abnormal. The prompt module 42 is electrically connected to the detection module 41, and the prompt module 42 is used to issue an alarm prompt when the detection module 41 detects that the telescopic position of the retractable module 11 is abnormal.

[0051] For example, the telescopic position of the retractable module 11 includes an initial position A where it does not extend out of the sill 30 and the hall door 20 is in an unlocked state, and a highest position B where it extends out of the sill 30 and extends into the groove 21 to lock the hall door 20. If the telescopic position of the door lock device 11 is between the initial position A and the highest position B, it is considered that the telescopic position of the retractable module 11 is abnormal.

[0052] If when the hall door 20 needs to be locked, the detection module 41 detects that the extended position of the retractable module 11 does not reach the highest position B, it is determined that the extended position of the retractable module 11 is abnormal and the hall door 20 is not locked in place. At this time, the hall door is likely to cause accidents such as the hall door, personnel or items falling into the elevator shaft due to impact. Therefore, when the prompt module 42 receives the abnormal situation that the detection module 41 detects that the extended position of the retractable module 11 does not reach the highest position B, it can issue an alarm prompt. The alarm prompt can be prompted by voice, light flashing, etc. For example, the voice prompt can be "The current hall door is not locked in place, please pay attention", or the prompt module 42 can include an elevator call device outside the elevator hall, and the elevator call device is used to flash a red light for prompt.

[0053] When it is necessary to unlock the landing door 20, if the detection module 41 detects that the retracted position of the retractable module 11 does not reach the initial position A, it is determined that the retracted position of the retractable module 11 is abnormal. At this time, the landing door 20 is not unlocked in place, and the landing door will not open. Therefore, when the prompt module 42 receives the abnormal situation that the detection module 41 detects that the extended position of the door lock device 11 does not reach the initial position A, it can issue an alarm prompt. The alarm prompt can be given by means of voice, light flashing, etc. For example, the voice prompt can be "The current landing door is not unlocked in place, please check", or the prompt module 42 can include an elevator external call device outside the elevator landing door, and the elevator external call device is made to flash a red light for prompt.

[0054] In this way, the present application detects whether the telescopic position of the retractable module 11 is abnormal by setting a safety detection device 40 on the elevator 100, so as to judge whether the landing door 20 is locked or unlocked in place, and can issue a safety prompt in time when an abnormal situation is detected, further ensuring the use safety of the landing door 20 of the elevator 100.

[0055] Please refer to Figure 7 , in some embodiments, the prompt module 42 includes an external call prompt unit 421. The external call prompt unit 421 is arranged in the external call device 50 of the elevator 100, and the external call prompt unit 421 is used to give an alarm prompt when it detects that the telescopic position of the retractable module 11 is abnormal.

[0056] Specifically, the external call prompt unit 421 can give a prompt by means of voice prompt, text or light prompt, etc., which is not limited here. The external call prompt unit 421 can control the display screen of the external call device 50 to display an alarm prompt in text form, or control the light of the external call device 50 to display a specific color, such as a red warning light, which is not limited here.

[0057] It can be understood that since the external call prompt unit 421 is arranged in the external call device 50 of the elevator 100 and the external call prompt unit 421 can control the display screen or light display of the external call device 50 to give an alarm prompt, therefore, the waiting area personnel outside the elevator or the safety inspection personnel can easily find that there is a problem with the landing door 20 corresponding to the current floor position, thus playing a warning role and being easy for safety inspection.

[0058] That is to say, when the safety detection device 40 of the present application detects that the telescopic position of the retractable module 11 is abnormal, it can give an alarm prompt through the external call prompt unit 421 installed in the external call device 50 of the elevator 100.

[0059] Please refer to Figure 8, in some embodiments, the safety detection device 40 further includes a pressure sensing module 43. The pressure sensing module 43 is disposed on the side wall 211 of the groove 21, and the pressure sensing module 43 is spaced apart from the telescopic module 11 extending into the groove 21 by a preset distance d. The pressure sensing module 43 is electrically connected to the detection module 41, and the detection module 41 is configured to determine that there is an external force pressing on the landing door 20 when detecting the induction signal sent by the pressure sensing module 43; and / or, the external call prompt unit 421 is further configured to give an alarm prompt when it is detected that there is an external force pressing on the landing door 20.

[0060] Specifically, the pressure sensing module 43 may be in the shape of a thin sheet or other shapes, as long as it can be installed and fixed on the side wall 211 of the groove 21.

[0061] When the pressure sensing module 43 is in the shape of a thin sheet, the pressure sensing module 43 can be fixedly arranged around the circumferential wall of the side wall 211 of the groove 21 in a circle, so that when the landing door 20 is externally pressed, it is ensured that the telescopic module 11 can contact the pressure sensing module 43, so that the pressure sensing module 43 can send out an induction signal in time.

[0062] In addition, the pressure sensing module 43 may also be embedded in the side wall 211 of the groove 21, as long as it can be pressed by the telescopic module 11, so that the pressure sensing module 43 can send out an induction signal in time.

[0063] The preset distance d between the pressure sensing module 43 and the telescopic module 11 extending into the groove 21 may be 0.2 cm, 0.3 cm, 0.4 cm, 0.5 cm, 0.6 cm, 0.7 cm, 0.8 cm, 0.9 cm, 1 cm or 1.2 cm, which is not limited herein. It can be understood that the smaller the preset distance d is, the closer the distance between the pressure sensing module 43 and the telescopic module 11 is, which means that a smaller external force pressing on the landing door 20 can trigger the pressure sensing module 43 to send out an induction signal. The larger the preset distance d is, the farther the distance between the pressure sensing module 43 and the telescopic module 11 is, which means that a larger external force pressing on the landing door 20 can trigger the pressure sensing module 43 to send out an induction signal.

[0064] Specifically, the pressure sensing module 43 can be triggered to detect whether it is in contact with the telescopic module 11 when the elevator is in the waiting idle mode, so as to detect whether the landing door 20 is externally pressed at this time. Among them, the waiting idle mode may refer to the idle state mode when the elevator is not used by passengers.

[0065] Such as Figure 5As shown, when the retractable module 11 extends from the sill into the groove 21 and reaches the extended position, the two contacts of the retractable module 11 come into contact connection with the two retracted and in-place contacts on its two sides, enabling the retractable module 11 to form an electrical circuit loop P2 through potential 1 and potential 2 of the external call panel 124. At this time, the pressure sensing module 43 is connected to the electrical circuit loop where the retractable module 11 is located through the SK relay.

[0066] At this time, please refer to Figure 3 . If the main board 121 detects that the elevator is in the waiting idle mode, the main board 121 can trigger the SK relay to close, so that the induction signal sent by the pressure sensing module 43 can be fed back to the main board 121 through the electrical circuit loop P2. After receiving the induction signal sent by the pressure sensing module 43, the main board 121 determines that the current landing door 20 is being squeezed, and thus can timely control the elevator to issue a prompt.

[0067] In this way, the safety detection device 40 of the present application can determine whether there is external force squeezing on the landing door 20 through the pressure sensing module 43 provided on the side wall 211 of the groove 21.

[0068] In some embodiments, the external call prompt unit 421 is further configured to give an alarm prompt when it detects that there is external force squeezing on the landing door 20. The external call prompt unit 421 can give a prompt in ways such as voice prompt, text or light prompt, etc., which is not limited here.

[0069] In one embodiment, as Figure 3 shown, when the SR relay is disconnected, it indicates that the retractable module 11 is in the extended state of extending into the groove 21 at this time. If the main board 121 can determine that the current landing door 20 is being squeezed after receiving the induction signal sent by the pressure sensing module 43 at this time, it can timely control the external call prompt unit 421 of the elevator to give a voice prompt.

[0070] In other embodiments of the present application, in addition to using the pressure sensing module to detect whether there is external force squeezing on the landing door, it is also possible to determine whether there is external force squeezing on the landing door through other means. When using other means to determine whether there is external force squeezing on the landing door, the external call prompt unit can also be used to give an alarm prompt when it detects that there is external force squeezing on the landing door.

[0071] It can be understood that since the external call prompt unit 421 is provided at the external call device 50 of the elevator 100, the waiting area personnel or safety inspection personnel outside the elevator can easily find that there is a problem with the landing door 20 corresponding to the current floor position, thus playing a warning role and being conducive to safety inspection.

[0072] That is, when the safety detection device 40 of the present application detects that there is an external force squeezing the landing door 20, an alarm prompt can be given through the external call prompt unit 421.

[0073] In some embodiments, the detection module 41 is further configured to determine the location information of the abnormal landing door 20 according to the external call address of the external call device 50 corresponding to the landing door 20. The prompt module 42 is configured to generate an alarm prompt according to the location information of the landing door 20 and the detection result of the locking or unlocking of the landing door.

[0074] Specifically, the location information of the landing door 20 may include the floor, the landing door number, or other information, which is not limited herein.

[0075] The alarm prompt can be given in the form of voice, text, or light flashing. For example, the voice prompt can be "There is an external force squeezing the current landing door, please pay attention."

[0076] It can be understood that each floor's external call device 50 is internally provided with a corresponding external call address. Therefore, the safety detection device 40 of the present application can lock the location information of the abnormal landing door 20 through the external call address, so that the waiting area personnel outside the elevator or the safety inspection personnel can easily find that there is a problem with the landing door 20 corresponding to the current floor position, playing a warning role and facilitating safety inspection.

[0077] For example, assume that there are a total of 4 floors in the building. The external call address of the first floor is "Address 1", the external call address of the second floor is "Address 2", the external call address of the third floor is "Address 3", and the external call address of the fourth floor is "Address 4". If the landing door corresponding to the second floor is squeezed, the corresponding external call prompt unit can determine the location information of the abnormal landing door 20 as the second floor according to the external call address of the second floor, and thus can issue an alarm prompt of "There is an external force squeezing the landing door on the second floor, please pay attention." If the telescopic position of the telescopic module 11 below the landing door corresponding to the third floor is abnormal, the corresponding external call prompt unit can determine the location information of the abnormal landing door 20 as the third floor according to the external call address of the third floor, and thus can issue an alarm prompt of "The telescopic position of the telescopic module 11 below the landing door on the third floor is abnormal, please pay attention."

[0078] In this way, the prompt module 42 of the present application can determine the location information of the abnormal landing door 20 through the detection module 41 and issue an alarm prompt more accurately.

[0079] In some embodiments, the prompt module 42 is communicatively connected to the server side, and the server side is communicatively connected to the user side. The prompt module 42 is further configured to send the alarm prompt to the user side through the server side.

[0080] Specifically, the server - side refers to the system or software component in network communication that is responsible for receiving, processing, and responding to requests from the client - side. In this application, the server - side acts as a mediator between the prompt module 42 and the client - side. It receives the alarm prompts from the prompt module 42 and sends the alarm prompts to the corresponding client - side.

[0081] The client - side refers to the electronic device or software used by the user for communicating with the server - side and receiving information. The electronic device can be, for example, a mobile phone, a computer, an iPad, or other devices, without limitation here.

[0082] In this application, the client - side can receive alarm prompts from the server - side. These alarm prompts can be presented in various forms, such as text messages, emails, or application notifications. The user of the client - side can remotely monitor the locking status of each landing door. When receiving an alarm prompt, the user can quickly respond to the alarm prompt and take necessary countermeasures.

[0083] In this way, the security detection device 40 of this application can also be communicatively connected to the server - side, enabling the server - side to promptly send alarm prompts to the client - side, realizing the remote monitoring of the landing doors of the elevator by the client - side.

[0084] This application also provides a security detection method, which is applied to detect the door lock device 10 in the above - mentioned embodiment. The security detection method includes:

[0085] 01: Detect whether the telescopic position of the telescopic module 11 is abnormal;

[0086] 02: When it is detected that the telescopic position of the telescopic module 11 is abnormal, issue an alarm prompt.

[0087] Please refer to Figure 3 , step 01 can be implemented by the detection module 41, and step 02 can be implemented by the prompt module 42. That is, the detection module 41 is used to detect whether the telescopic position of the telescopic module 11 is abnormal; the prompt module 42 is used to issue an alarm prompt when it is detected that the telescopic position of the telescopic module 11 is abnormal.

[0088] Specifically, this application can detect in real - time whether the telescopic position of the telescopic module 11 is abnormal, and thus issue an alarm prompt in a timely manner when it is detected that the telescopic position of the telescopic module 11 is abnormal.

[0089] This application can also trigger the detection of whether the telescopic position of the telescopic module 11 is abnormal only at a specific moment when the landing door needs to be used.

[0090] In one embodiment, for example, please refer to Figure 9, when the elevator is in the normal call mode and a user on the 3rd floor sends a call signal, and the car of the elevator 100 needs to rise from the 1st floor to the 3rd floor to open, when the detection module 41 receives the call signal sent by the user on the 3rd floor, the car of the elevator is at the 1st floor at the current moment. The detection module 41 can first detect whether the extended position of the telescopic module 11 reaches the highest position B, so as to judge that the extended position of the telescopic module 11 is abnormal and judge whether the landing door 20 is locked in place. If it is detected that the landing door 20 is not locked in place at this time, the landing door will easily cause accidents such as the landing door, personnel or objects falling into the elevator shaft due to impact. Therefore, when the prompt module 42 receives the abnormal situation that the detection module 41 detects that the extended position of the telescopic module 11 does not reach the highest position B, it can issue an alarm prompt regarding the abnormal locking of the landing door on the 3rd floor, so as to prompt the call user on the 3rd floor to pay attention to safety.

[0091] In addition, when the detection module 41 receives the call signal sent by the user on the 3rd floor, if the detection module 41 detects that the extended position of the telescopic module 11 reaches the highest position B, then after the car of the elevator 100 normally rises to the 3rd floor and needs to unlock the landing door on the 3rd floor, the detection module 41 can detect again whether the unlocking of the landing door on the 3rd floor is abnormal. If it is detected that the landing door 20 is not unlocked in place at this time, that is, it is detected that the retracted position of the telescopic module 11 does not reach the initial position A, then the landing door will not open at this time. Therefore, when the prompt module 42 receives the abnormal situation that the detection module 41 detects that the extended position of the telescopic module 11 does not reach the initial position A, it can issue an alarm prompt regarding the abnormal unlocking of the landing door on the 3rd floor, so as to prompt the call user on the 3rd floor that the landing door will not open, enabling the safety personnel to check in time.

[0092] It can be understood that the door lock device 10 and the safety detection device 40 of the present application can both be installed on the landing door 20 of the elevator 100 on each floor, so as to perform safety detection on the landing door 20 on each floor.

[0093] In another embodiment, please refer to Figure 10, the elevator 100 can be set to perform specific safety detections on each landing door 20 of the elevator 100 in a safety mode within a specific time. When the elevator is in the standby mode (i.e., non-call mode) and the elevator safety mode is activated, the telescopic positions of the telescopic modules 11 of the door lock devices 10 on each landing door 20 can be detected simultaneously for abnormalities, or detected one by one for abnormalities. When it is detected that the extended position of the telescopic module 11 of the door lock device 10 on a certain landing door 20 does not reach the highest position B, it is determined that the landing door 20 is not locked in place, and thus a corresponding alarm prompt for the landing door 20 on that floor is issued. When it is detected that the retracted position of the telescopic module 11 of the door lock device 10 on a certain landing door 20 does not reach the initial position A, it is determined that the landing door 20 is not unlocked in place, and thus a corresponding alarm prompt for the landing door 20 on that floor is issued.

[0094] In addition, when the safety mode is activated, it is also possible to detect whether the landing door 20 is subjected to external force extrusion through the pressure sensing module 43 on each landing door 20, or detect one by one whether the landing door 20 is subjected to external force extrusion, thereby avoiding the situation where the landing door 20 falls into the elevator shaft due to extrusion. When it is detected that the pressure sensing module 43 on a certain landing door 20 contacts the telescopic module 11 and emits an induction signal, it is determined that the landing door 20 is subjected to external force extrusion, and thus a corresponding alarm prompt for the landing door 20 on that floor is issued.

[0095] Among them, the alarm prompt can be made through means such as voice and light flashing. For example, the voice prompt can be "The current landing door is not locked in place, please pay attention", or the prompt module 42 can include the elevator external call device outside the elevator hall, and the elevator external call device is made to flash red lights for prompt.

[0096] In addition, the alarm prompt can be sent to the user terminal through the server side. For example, it can be sent to the elevator safety detection application program on the user's mobile phone, so as to promptly prompt the user that there is an abnormality in the landing door of the elevator.

[0097] In this application, by setting the door lock device 10 with the telescopic module 11 below the landing door 20 of the elevator 100, when the telescopic module 11 extends into the groove 21 on the landing door 20, it can simultaneously lock and protect the landing door 20, and can effectively prevent the situation where the landing door 20 of the elevator 100 is separated due to being impacted by abnormal external force and causes a falling elevator accident.

[0098] In addition, in this application, by setting the safety detection device 40 on the elevator 100 to detect whether the telescopic position of the telescopic module 11 is abnormal, thereby judging whether the landing door 20 is locked or unlocked in place, and can issue a safety prompt in a timely manner when an abnormal situation is detected, further ensuring the safe use of the landing door 20 of the elevator 100.

[0099] The present application also provides a security detection system. The security detection system includes a door lock device 10 and a security detection device 40. The security detection device 40 is electrically connected to the door lock device 10. The security detection device 40 is used to detect whether the door lock device 10 is abnormal, or the security detection system executes the security detection method described in the above embodiments.

[0100] When the retractable module 11 below the elevator landing door 20 extends into the groove 21 on the landing door 20, the security detection system of the present application can simultaneously lock and protect the landing door 20, and can effectively prevent the situation that the landing door 20 of the elevator 100 is separated due to being impacted by abnormal external force, resulting in an elevator falling accident.

[0101] In addition, the security detection system of the present application detects whether the retractable position of the retractable module 11 is abnormal by setting a security detection device 40 on the elevator 100, so as to judge whether the landing door 20 is locked or unlocked in place, and can give a security prompt in time when an abnormal situation is detected, further ensuring the use safety of the landing door 20 of the elevator 100.

[0102] The above embodiments only represent several implementation manners of the present application, and the description thereof is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
