Description

Technical Field

[0001] This utility model belongs to the field of door lock technology, and in particular relates to an intelligent door lock, intelligent door lock components and a door. Background Technology

[0002] As a smart home product, smart locks have gradually gained consumer recognition and favor for their convenience, security, and technological sophistication, and are increasingly being used in people's daily lives. To ensure the security of smart locks, a detection mechanism is usually incorporated to monitor the door's open / closed status, thus improving safety. However, existing smart locks suffer from poor sensitivity in detecting this open / closed state. Utility Model Content

[0003] The purpose of this utility model is to provide a smart door lock, a smart door lock component and a door, which aims to solve the technical problem of poor sensitivity in detecting the open and closed status of smart door locks in the prior art.

[0004] This utility model is implemented as follows: Firstly, it provides an intelligent door lock, which includes a lock shell, a bolt, and a magnetoresistive sensor for sensing and cooperating with a magnetic component. The lock shell is provided with a bolt groove, and the bolt is slidably disposed in the bolt groove. The lock shell is also provided with a mounting groove, and the magnetoresistive sensor is installed in the mounting groove. The openings of the mounting groove and the bolt groove are both located on the same side of the lock shell.

[0005] The opening and closing status of a door can be determined by the magnitude of the magnetic flux detected by a magnetoresistive sensor. For example, when the door is fully closed, the distance between the magnetoresistive sensor and the magnetic component is at its shortest, and the magnetic flux detected by the magnetoresistive sensor can reach or exceed a preset threshold. When the door is open, the distance between the magnetoresistive sensor and the magnetic component increases, and the magnetic flux detected by the magnetoresistive sensor is less than the preset threshold. Compared with existing smart door locks, where the bolt typically extends or retracts into the lock body from the opening of the bolt groove, and the opening of the bolt groove is generally located closest to the door frame, in this application, by mounting the magnetic component on the door frame and placing the mounting groove and the bolt groove opening on the same side of the lock housing, and then mounting the magnetoresistive sensor in the mounting groove, the distance between the magnetoresistive sensor and the magnetic component can be smaller when the door is closed. When the position of the magnetoresistive sensor changes, the change in magnetic field strength per unit distance is greater, improving the detection sensitivity.

[0006] In one optional embodiment, the lock housing includes a cylindrical body and a mounting cover plate, the latch groove is located inside the cylindrical body, the opening of the latch groove and the mounting cover plate are both located at the same end of the cylindrical body, and the mounting groove is disposed on the mounting cover plate.

[0007] The supporting shell is divided into two parts: the cylindrical body and the mounting cover plate, with the mounting groove located on the mounting cover plate. The mounting cover plate provides more installation space for the mounting groove, making its installation more convenient. Simultaneously, during lock housing installation, the mounting cover plate can abut against the side of the door, positioning the lock housing and ensuring a more precise and stable installation.

[0008] In one alternative embodiment, the lock housing includes a cylindrical portion and a mounting cover plate. The end of the cylindrical portion extends outward to form an extension portion. The mounting cover plate abuts against the extension portion. The mounting groove includes a first sub-groove and a second sub-groove. The first sub-groove is located on the extension portion, and the second sub-groove is located on the mounting cover plate.

[0009] By extending the end of the cylindrical section outward to form an extension, and then connecting the mounting cover plate to the extension, the contact area between the mounting cover plate and the cylindrical section is increased, making the connection between the mounting cover plate and the cylindrical section more secure. Furthermore, the mounting groove can be divided into a first sub-groove and a second sub-groove, with the first sub-groove and the second sub-groove respectively located on the extension and the mounting cover plate. This allows for a larger accommodating space in the depth direction of the mounting groove, thereby making the installation of the magnetoresistive sensor more secure.

[0010] In an optional embodiment, the wall of the mounting groove is in communication with the wall of the locking tongue groove.

[0011] The mounting groove and the latch groove are arranged adjacent to each other, and the groove walls of the mounting groove and the latch groove are connected to each other. The mounting groove and the latch groove can be integrally formed during the lock case manufacturing process, making the manufacturing of the lock case more convenient.

[0012] In an optional embodiment, an isolating member is further provided at the opening of the latch groove, the isolating member is arranged around the latch, and the isolating member is used to isolate the mounting groove from the latch groove.

[0013] An isolator is provided at the opening of the latch groove, and the isolator surrounds the latch. The isolator isolates the mounting groove from the latch groove and supports the magnetoresistive sensor, preventing it from falling into the latch groove after installation. It also isolates the latch from the magnetoresistive sensor, preventing the latch from contacting the sensor during movement, making the installation and fixation of the magnetoresistive sensor safer and more secure.

[0014] In an optional embodiment, a limiting structure is provided between the magnetoresistive sensor and the mounting slot to prevent the magnetoresistive sensor from detaching from the mounting slot.

[0015] A limiting structure is provided between the magnetoresistive sensor and the mounting slot to prevent the magnetoresistive sensor from coming out of the mounting slot after it is installed in the mounting slot, thus making the installation of the magnetoresistive sensor more stable.

[0016] In an optional embodiment, the limiting structure includes a stepped surface disposed on the magnetoresistive sensor and a protrusion located on the inner wall of the mounting groove, the protrusion abutting against the stepped surface to limit the magnetoresistive sensor.

[0017] After the magnetoresistive sensor is installed in the mounting slot, the protrusions on the inner wall of the mounting slot abut against the stepped surface, thereby limiting the position of the magnetoresistive sensor and making the installation of the magnetoresistive sensor more stable.

[0018] In one optional embodiment, a connecting wire harness is connected to the magnetoresistive sensor, and a wire-passing hole is provided at the bottom of the mounting groove for the connecting wire harness to pass through.

[0019] The bottom of the mounting slot has a wire hole, which allows the connecting wires to be connected to the control circuit board inside the lock body. This avoids bending of the connecting wires and makes it easier to connect the magnetoresistive sensor to the circuit board.

[0020] Secondly, a smart door lock assembly is provided, including the smart door lock described in any of the above claims, and further including a strike plate and a magnetic component. The strike plate is used to be installed on a door frame. The strike plate has a latch hole for interlocking with the latch portion. The strike plate is provided with a snap-fit ​​structure for installing the magnetic component. The magnetic component is installed on the door frame through the strike plate.

[0021] The door frame is equipped with a strike plate that works in conjunction with the latch to increase the strength of the door frame in certain areas, making the smart lock safer to use. The strike plate also features a snap-fit ​​structure for mounting magnetic components. The magnetic components can be first installed onto the strike plate using this structure, and then the strike plate can be installed onto the door frame. This achieves the final installation of the magnetic components without damaging the door frame structure, making the installation of the magnetic components more stable and convenient.

[0022] Thirdly, a door is provided, comprising the smart door lock described in any of the above claims.

[0023] The first aspect of this invention provides the following technical advantages: During operation, the magnetic component can be installed on the door frame, and the lock housing can be installed on the door body. The lock housing has a latch groove, within which the latch can slide. The lock housing also has a mounting groove, with the openings of the mounting groove and the latch groove located on the same side of the lock housing. A magnetoresistive sensor is installed in the mounting groove, allowing it to face the magnetic component. Simultaneously, the magnetoresistive sensor and the magnetic component work together, allowing the magnetoresistive sensor to detect the magnetic flux at its location. The magnitude of the magnetic flux detected by the magnetoresistive sensor can be used to determine the door's open / closed state. For example, when the door is fully closed, the distance between the magnetoresistive sensor and the magnetic component is at its shortest, and the magnetic flux detected by the magnetoresistive sensor can reach or exceed a preset threshold. When the door is open, the distance between the magnetoresistive sensor and the magnetic component increases, and the magnetic flux detected by the magnetoresistive sensor is less than the preset threshold. Compared to existing smart locks, where the bolt typically extends or retracts into the lock body from an opening in the bolt groove, and this opening is usually located closest to the door frame, this application allows for a smaller gap between the magnetoresistive sensor and the magnetic component when the door is closed. This results in a greater change in magnetic field strength per unit distance when the magnetoresistive sensor's position changes, thus improving detection sensitivity.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0040] Please refer to Figures 1 to 4 As shown in the present invention, in a first aspect, a smart door lock is provided. The smart door lock includes a lock shell 1, a bolt 8, and a magnetoresistive sensor 2 for sensing and cooperating with a magnetic component 3. The lock shell 1 is provided with a bolt groove 13, and the bolt 8 is slidably disposed in the bolt groove 13. The lock shell 1 has a mounting groove 14, and the magnetoresistive sensor 2 is installed in the mounting groove 14. The openings of the mounting groove 14 and the bolt groove 13 are both located on the same side of the lock shell 1.

[0041] Specifically, the lock housing 1 refers to a shell-shaped component with a certain accommodating space, and the latch groove 13 refers to a groove structure with a certain depth, wherein at least a portion of the lock housing 1 can be recessed inward to form the latch groove 13. The latch 8 refers to a columnar component with a certain length, and the latch 8 is slidably disposed within the latch groove 13. The lock housing 1 also has components for driving the movement of the latch 8, the structure of which is a technical means well known to those skilled in the art and will not be described in detail here. The mounting groove 14 also refers to a groove structure with a certain depth, and the mounting groove 14 can be formed by recessing at least a portion of the lock housing 1 inward.

[0042] Magnetic component 3 refers to a component that can generate a constant magnetic field. Magnetic component 3 can be a permanent magnet made of magnetic material, or it can be an electromagnet that converts electrical energy into a magnetic field through inductance. Magnetic component 3 can be directly installed onto the door frame, or it can be indirectly installed onto the door frame through other components, such as by installing magnetic component 3 onto the strike plate 4, and then installing the strike plate 4 onto the door frame. Magnetoresistive sensor 2 refers to a sensor manufactured using the magnetoresistive effect. Its working principle is to convert changes in magnetic field into changes in its own resistance, thereby detecting the strength of the magnetic field.

[0043] Inductive cooperation refers to the cooperation between the magnetoresistive sensor 2 and the magnetic component 3 by sensing the change in the magnetic field generated by the magnetic component 3. The sensing between the two is generally unidirectional.

[0044] The smart door lock provided in this embodiment of the utility model can install a magnetic component 3 on the door frame and a lock housing 1 on the door body during operation. The lock housing 1 has a latch groove 13, and the latch 8 is slidably disposed within the latch groove 13. The lock housing 1 also has a mounting groove 14, with the openings of the mounting groove 14 and the latch groove 13 located on the same side of the lock housing 1. A magnetoresistive sensor 2 is installed within the mounting groove 14, allowing the magnetoresistive sensor 2 to face the magnetic component 3. Simultaneously, the magnetoresistive sensor 2 and the magnetic component 3 work together inducedly, allowing the magnetoresistive sensor 2 to detect the magnetic flux at its location. The opening and closing state of the door can be determined by the magnitude of the magnetic flux detected by the magnetoresistive sensor 2. For example, when the door is fully closed, the distance between the magnetoresistive sensor 2 and the magnetic component 3 is the shortest, and the magnetic flux detected by the magnetoresistive sensor 2 can reach or exceed a preset threshold. When the door is open, the distance between the magnetoresistive sensor 2 and the magnetic component 3 increases, and the magnetic flux detected by the magnetoresistive sensor 2 is less than the preset threshold. Compared to existing smart locks, where the bolt 8 typically extends from or retracts into the lock body through the opening of the bolt groove 13, and the opening of the bolt groove 13 is generally located closest to the door frame, in this application, by mounting the magnetic component 3 on the door frame and aligning the mounting groove 14 and the opening of the bolt groove 13 on the same side of the lock housing 1, and then mounting the magnetoresistive sensor 2 in the mounting groove 14, the distance between the magnetoresistive sensor 2 and the magnetic component 3 can be reduced when the door is closed. When the position of the magnetoresistive sensor 2 changes, the change in magnetic field strength per unit distance is greater, improving detection sensitivity.

[0045] In an optional embodiment, please refer to Figure 1 The magnetoresistive sensor 2 is a TMR (Tunnel MagnetoResistance) sensor. Specifically, the TMR sensor refers to a magnetoresistive sensor 2 based on the quantum tunneling effect, which has higher sensitivity compared to other types of magnetoresistive sensors 2. In this embodiment, by using a TMR sensor, the sensitivity of magnetic field detection can be further improved. Thus, when the position of the lock body relative to the magnetic component 3 changes, the magnetoresistive sensor 2 can more sensitively detect changes in magnetic flux, making the smart lock more sensitive in detecting the opening and closing status of the door.

[0046] In one embodiment, see Figures 2 to 4The lock housing 1 includes a cylindrical body 11 and a mounting cover plate 12. A latch groove 13 is located inside the cylindrical body 11, and the opening of the latch groove 13 and the mounting cover plate 12 are both located at the same end of the cylindrical body 11. A mounting groove 14 is disposed on the mounting cover plate 12. Specifically, the cylindrical body 11 refers to a cylindrical structure with a certain depth, and the cross-section of the cylindrical body 11 can be circular, elliptical, or polygonal. The mounting cover plate 12 refers to a plate-like structure with a certain thickness, and the opening of the mounting cover plate 12 and the latch groove 13 are located at the same end of the cylindrical body 11. In this embodiment, by dividing the lock housing 1 into two parts, the cylindrical body 11 and the mounting cover plate 12, and disposing of the mounting groove 14 on the mounting cover plate 12, a larger installation space can be provided for the mounting groove 14 through the mounting cover plate 12, making the installation of the mounting groove 14 more convenient. Meanwhile, during the installation of the lock housing 1, the mounting cover 12 can abut against the side of the door to position the lock housing 1, thereby making the installation position of the lock housing 1 more precise and stable.

[0047] In one embodiment, see Figures 2 to 4 The lock case 1 includes a cylindrical part 11 and a mounting cover plate 12. The end of the cylindrical part 11 extends outward to form an extension part 15. The mounting cover plate 12 abuts against the extension part 15. The mounting groove 14 includes a first sub-groove 141 and a second sub-groove 142. The first sub-groove 141 is located on the extension part 15, and the second sub-groove 142 is located on the mounting cover plate 12.

[0048] Specifically, the extension 15 refers to a plate-like structure with a certain thickness. The extension 15 is formed by extending the end of the cylindrical part 11 outwards. The extension 15 is generally integrally formed with the cylindrical part 11, for example, by stamping. The mounting cover 12 is then connected to the extension 15 by snap-fitting, fastener connection, or welding. The first sub-slot 141 and the second sub-slot 142 refer to different positions of the mounting groove 14. The first sub-slot 141 and the second sub-slot 142 together form the aforementioned mounting groove 14.

[0049] In this embodiment, by extending the end of the cylindrical part 11 outward to form an extension part 15, and then connecting the mounting cover plate 12 to the extension part 15, the contact area between the mounting cover plate 12 and the cylindrical part 11 can be increased, making the connection between the mounting cover plate 12 and the cylindrical part 11 more secure.

[0050] Furthermore, the mounting slot 14 can be divided into a first sub-slot 141 and a second sub-slot 142, and the first sub-slot 141 and the second sub-slot 142 are respectively disposed on the extension 15 and the mounting cover plate 12, so that the mounting slot 14 can have a larger accommodating space in the depth direction, thereby making the installation of the magnetoresistive sensor 2 more secure.

[0051] In an optional embodiment, please refer to Figure 3The mounting cover 12 and the extension 15 can be fixed together by riveting. Specifically, riveting is a method of connecting two objects together. Riveting can be achieved by riveting two parts together with rivets, or by bending a portion of the mounting cover 12 through the extension 15 to achieve the riveting. By using riveting, the connection between the mounting cover 12 and the extension 15 is made stronger and more convenient.

[0052] In one embodiment, see Figure 4 The wall of the mounting groove 14 is connected to the wall of the latch groove 13. In this embodiment, the mounting groove 14 and the latch groove 13 can be arranged adjacent to each other, and the walls of the mounting groove 14 and the latch groove 13 can be connected to each other. The mounting groove 14 and the latch groove 13 can be integrally formed during the manufacturing process of the lock housing 1, making the manufacturing of the lock housing 1 more convenient.

[0053] In one embodiment, see Figure 1 An isolator 9 is also provided at the opening of the latch groove 13. The isolator 9 surrounds the latch 8 and is used to isolate the mounting groove 14 from the latch groove 13. Specifically, the isolator 9 is a ring structure with a certain diameter, and the material of the isolator 9 can be plastic, metal, or polymer material, etc. In this embodiment, by providing an isolator 9 at the opening of the latch groove 13 and surrounding the latch 8, the mounting groove 14 and the latch groove 13 can be isolated from each other by the isolator 9, and the magnetoresistive sensor 2 can be supported by the isolator 9 to avoid the risk of the magnetoresistive sensor 2 falling into the latch groove 13 after being installed in the mounting groove 14. At the same time, the latch 8 and the magnetoresistive sensor 2 can also be isolated to prevent the latch 8 from touching the magnetoresistive sensor 2 during movement, making the installation and fixation of the magnetoresistive sensor 2 safer and more secure.

[0054] In an optional embodiment, please refer to Figure 1 The isolator 9 includes an isolating ring, and the outer wall of the isolating ring abuts against the inner wall of the locking tongue groove 13, which can make the installation of the isolator 9 more stable.

[0055] In one embodiment, see Figure 5 A limiting structure 7 is provided between the magnetoresistive sensor 2 and the mounting groove 14 to prevent the magnetoresistive sensor 2 from detaching from the mounting groove 14. Specifically, the limiting structure 7 refers to a component or assembly that can limit the object, and the limiting structure 7 can limit the object by snapping, abutting, or clamping. In this embodiment, by providing the limiting structure 7 between the magnetoresistive sensor 2 and the mounting groove 14, the magnetoresistive sensor 2 is prevented from detaching from the mounting groove 14 after it is installed in the mounting groove 14, making the installation of the magnetoresistive sensor 2 more stable.

[0056] In one embodiment, see Figure 5 The limiting structure 7 includes a stepped surface 71 disposed on the magnetoresistive sensor 2 and a protrusion 72 located on the inner wall of the mounting groove 14. The protrusion 72 abuts against the stepped surface 71 to limit the magnetoresistive sensor 2. Specifically, the stepped surface 71 refers to the structure formed at the connection of two components of different sizes. For example, the magnetoresistive sensor 2 may include a first part and a second part, wherein the width of the first part is greater than that of the second part. In this case, a stepped surface 71 is formed at the connection between the first part and the second part. The protrusion 72 refers to a component with a certain height. The protrusion 72 can be formed on the inner wall of the mounting groove 14 by making the width of the first sub-groove 141 greater than the width of the second sub-groove 142. In this embodiment, after the magnetoresistive sensor 2 is installed in the mounting groove 14, the protrusion 72 disposed on the inner wall of the mounting groove 14 abuts against the stepped surface 71, thereby limiting the magnetoresistive sensor 2 and making the installation of the magnetoresistive sensor 2 more stable.

[0057] In one embodiment, see Figure 7 The smart door lock also includes a control unit 5 and a communication module 6. Both the control unit 5 and the communication module 6 are mounted on the lock housing 1, and the control unit 5 is electrically connected to the magnetoresistive sensor 2 and the communication module 6.

[0058] Specifically, control unit 5 refers to a component that can process information and perform logical operations. Control unit 5 can be an MCU (Microcontroller Unit), PLC (Programmable Logic Controller), or DSC (Digital Signal Controller), etc. Communication module 6 refers to an electrical component that can communicate with other devices. Communication module 6 can use methods such as Bluetooth, WIFI, LoRa, or cellular networks to establish a communication connection with the server or control terminal.

[0059] In this embodiment, a control unit 5 and a communication module 6 are installed on the lock housing 1, and the control unit 5 is electrically connected to both the magnetoresistive sensor 2 and the communication module 6. During operation, the control unit 5 can determine the door's open / closed state by collecting detection data from the magnetoresistive sensor 2, and upload the result to the server via the communication module 6. Customers can then view the door's open / closed state through a control terminal connected to the server, making the smart lock safer and more convenient to use.

[0060] In one embodiment, see Figure 1 and Figure 2 A connecting wire harness 10 is connected to the magnetoresistive sensor 2, and a wire-passing hole 143 for the connecting wire harness 10 to pass through is provided at the bottom of the mounting groove 14. Specifically, the connecting wire harness 10 refers to a structure composed of multiple wires, and its function is generally to connect the magnetoresistive sensor 2 to the control circuit board. The wire-passing hole 143 refers to a through-hole structure with a certain area, which penetrates the side wall of the lock housing 1. In this embodiment, by providing a wire-passing hole 143 at the bottom of the mounting groove 14, the connecting wire harness 10 can be connected to the control circuit board located inside the lock body through the wire-passing hole 143, which can avoid bending of the connecting wire harness 10 and make it easier to connect the magnetoresistive sensor 2 to the circuit board.

[0061] Secondly, a smart door lock component is provided; please refer to [link / reference]. Figure 1 and Figure 6 The smart door lock, including any of the above-mentioned features, further includes a strike plate 4 and a magnetic component 3. The strike plate 4 is used to be installed on the door frame. The strike plate 4 has a latch hole 42 for interlocking with the latch 8. The strike plate 4 is provided with a snap-fit ​​structure 41 for installing the magnetic component 3. The magnetic component 3 is installed on the door frame through the strike plate 4.

[0062] Specifically, the strike plate 4 refers to a plate-shaped component with a certain area. The strike plate 4 can be installed on the door frame by means of snap-fit, welding, or fastener connection. The latch hole 42 refers to a through-hole structure provided on the strike plate 4, which generally penetrates the strike plate 4. When the strike plate 4 is installed on the door frame, the strike plate 4 covers the opening of the latch receiving groove on the door frame, and the position of the latch hole 42 matches the position of the latch receiving groove, so that the latch 8 can be inserted into the latch receiving groove after passing through the latch hole 42. The snap-fit ​​structure 41 refers to a structure used to fix other objects. The snap-fit ​​structure 41 can be a hole structure, a groove structure, or a clamping structure, etc.

[0063] In this embodiment, by installing a strike plate 4 on the door frame and having it cooperate with the latch 8, the strength of the door frame in a local area can be increased, making the use of the smart door lock safer. Simultaneously, a snap-fit ​​structure 41 for installing the magnetic component 3 is provided on the strike plate 4. The magnetic component 3 can be first installed onto the strike plate 4 via the snap-fit ​​structure 41, and then the strike plate 4 can be installed onto the door frame, thus achieving the final installation of the magnetic component 3 onto the door frame. This makes the installation of the magnetic component 3 more stable and convenient without damaging the structure of the door frame.

[0064] In one embodiment, see Figure 6The snap-fit ​​structure 41 includes a snap-fit ​​hole 411, and the cross-sectional shape of the snap-fit ​​hole 411 matches the cross-sectional shape of the magnetic component 3. Specifically, the snap-fit ​​hole 411 refers to a hole structure with a certain depth, and the snap-fit ​​hole 411 is usually provided through the snap-fit ​​plate 4 along the thickness direction of the snap-fit ​​plate 4. The cross-section of the snap-fit ​​hole 411 refers to the cross-section taken by a plane perpendicular to the depth direction of the snap-fit ​​hole 411. The cross-section of the magnetic component 3 refers to the cross-section taken by a plane perpendicular to the height direction of the magnetic component 3. In this embodiment, by providing a snap-fit ​​hole 411 on the snap-fit ​​plate 4, and by adapting the cross-sectional shape of the snap-fit ​​hole 411 to the cross-sectional shape of the magnetic component 3, the magnetic component 3 can be snapped into the snap-fit ​​hole 411 by a tight fit during the installation process, thereby simplifying the structure of the snap-fit ​​structure 41 and making the installation of the magnetic component 3 more secure.

[0065] In one embodiment, see Figure 6 The latch plate 4 has a connecting opening 43, which connects the side wall of the snap-fit ​​hole 411 and the side wall of the latch bolt hole 42. Specifically, the connecting opening 43 refers to an opening structure with a certain width. In this embodiment, by providing a connecting opening 43 on the latch plate 4 and connecting the side wall of the snap-fit ​​hole 411 and the side wall of the latch bolt hole 42 through the connecting opening 43, the side wall of the snap-fit ​​hole 411 is discontinuous due to the presence of the connecting opening 43. Therefore, when the side wall of the snap-fit ​​hole 411 is subjected to a large compressive force, the latch plate 4 can deform at the connecting opening 43, making the diameter of the snap-fit ​​hole 411 slightly larger. This can prevent the magnetic component 3 from being compressed and damaged when installed inside the snap-fit ​​hole 411, making the installation of the magnetic component 3 safer.

[0066] Thirdly, a door is provided, comprising the smart door lock described above. A lock housing 1 is mounted on the door body, a magnetoresistive sensor 2 is disposed on the lock housing 1, and a magnetic component 3 is mounted on the door frame via a strike plate 4. The positions of the magnetoresistive sensor 2 and the magnetic component 3 are matched. It is understood that the beneficial effects of the third aspect can be found in the relevant descriptions in the first aspect above, and will not be repeated here.
