DETAILED DESCRIPTION

[0048] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0050] Reference below Figure 1-Figure 15 The door lock assembly 100 according to the embodiment of the utility model is described. By setting three micro switches, the position arrangement of the first micro switch 18, the second micro switch 15, and the third micro switch 16 can respectively realize accurate monitoring of the position area of ​​the central control crank 10, the child lock worm gear 9, and the inner opening clutch rod 8, and then accurately determine whether the door lock is in the insurance state or the insurance release state, thereby ensuring the safety and effectiveness of the use of the door lock assembly 100.

[0051] Reference below Figure 1-Figure 15 The door lock assembly 100 according to the embodiment of the present utility model is described, including: a central control worm gear 1, a mechanical lock 5, a central control connecting rod 2, a central control crank 10, an outer opening component, an inner opening component and a first micro switch 18.

[0052] Among them, the central control worm gear 1, the mechanical lock 5, the central control connecting rod 2 and the central control crank 10 are all installed on the door lock housing 12, and the central control connecting rod 2 and the central control crank 10 are connected and linked; the mechanical lock 5 and the central control worm gear 1 are used to respectively push the central control connecting rod 2 to move to drive the outer opening component to switch between the safety state and the unsafe state, and the central control connecting rod 2 is suitable for driving the central control crank 10 to drive the inner opening component to switch between the safety state and the unsafe state; the first micro switch 18 is suitable for pressing and contacting the central control crank 10 when the outer opening component or the inner opening component is switched to the safety state.

[0053] In practice, when the central control worm gear 1 rotates, the central control worm gear 1 drives the central control connecting rod 2 to move, and the central control connecting rod 2 is connected to the central control crank 10, thereby driving the central control crank 10 to rotate. The rotation of the central control crank 10 in different directions can cause the inner opening component to switch between the safety-on state and the safety-off state. The central control crank 10 is hinged to the central control connecting rod 2, and the central control crank 10 can drive the central control connecting rod 2 to move when it rotates. The movement of the central control connecting rod 2 can switch the outer opening component between the safety-off state and the safety-on state; the position change of the central control crank 10 can be detected by the first microswitch 18, which is equivalent to the first microswitch 18 being able to detect the safety-on state or the central control safety-off state of the outer opening component and the inner opening component driven by the central control worm gear 1 and the central control crank 10.

[0054] Furthermore, the first connecting portion 25 of the central control link 2 is connected to the mechanical lock 5, and the mechanical lock 5 can rotate relative to the door lock housing 12, that is, when the mechanical lock 5 is driven, the central control link 2 can be driven to move, so that the central control link 2 drives the outer opening component to switch between unlocking and engaging the safety, and the central control link 2 and the central control crank 10 are always hinged, that is, the movement of the central control link 2 and the central control crank 10 move together, so that the state of the central control crank 10 can be detected by the first microswitch 18, and the state of the mechanical lock 5 can also be detected.

[0055] Specifically, the central control worm wheel 1 is provided with a first limit block 13, and the second side surface 132 of the first limit block 13 contacts the first contact portion 22 of the central control link 2, so that when the central control worm wheel 1 rotates clockwise, it can drive the central control link 2 toward Figure 1 The hinged portion 21 of the central control link 2 is hinged to the third connection portion 101 of the central control crank 10. The rotation of the central control worm gear 1 will drive the central control link 2 to move, thereby driving the central control crank 10 to rotate. For example, when the central control worm gear 1 rotates clockwise and drives the central control link 2 toward Figure 1 When the central control link 2 moves to the right side, the central control crank 10 drives the central control crank 10 to rotate clockwise, so that the outer opening component is switched to the release state; similarly, when the central control worm gear 1 rotates counterclockwise, the first side surface 131 of the first limit block 13 approaches the second contact portion 23 of the central control link 2 and contacts to drive the central control link 2 toward Figure 1 The left side of the central control crank 10 rotates counterclockwise, the central control connecting rod 2 secures the outer opening component and the central control crank 10 secures the inner opening component. The movement of the central control connecting rod 2 is realized by the rotation of the central control worm gear 1, that is to say, the rotation of the central control worm gear 1 can release or secure the outer opening component, and can also release or secure the inner opening component.

[0056] Therefore, the first micro switch 18 detects the central control crank 10, which can not only detect the insurance state or the uninsured state of the outer opening component and the inner opening component driven by the central control worm gear 1 and the central control crank 10, but also detect the insurance state or the uninsured state of the mechanical lock 5, that is, the insurance state or the uninsured state of the central control lock and the insurance state or the uninsured state of the mechanical lock 5 are uniformly detected, thereby realizing the functional integration of the two.

[0057] In some embodiments, the central control crank 10 is provided with a protrusion 102, and the door lock housing 12 is provided with a first mounting groove 123, the first mounting groove 123 is open along the crank center axis 124 of the central control crank 10 to form a first movable opening 1232, and the first micro switch 18 is installed in the first mounting groove 123 and at least partially extends from the first movable opening 1232 to press against the protrusion 102.

[0058] In practice, when the central control crank 10 is Figure 1When the central control crank 10 rotates counterclockwise, the raised portion 102 of the central control crank 10 contacts the first micro switch 18, thereby judging that the inner opening component is in the insurance state. The counterclockwise rotation of the central control crank 10 will drive the central control connecting rod 2 to move, so that the central control connecting rod 2 switches the outer opening component to the insurance state. In addition, when the central control crank 10 rotates along the Figure 1 When rotating clockwise, the protrusion 102 of the central control crank 10 is away from the first micro switch 18, so that it is judged that the inner opening assembly is in the released state. The clockwise rotation of the central control crank 10 can change the relationship between the central control connecting rod 2 and the outer opening assembly, so that the outer opening assembly is switched to the released state. Therefore, by providing the first micro switch 18, it is convenient to detect the position state of the central control crank 10, and then detect whether the inner opening assembly and the outer opening assembly are in the on state or released state.

[0059] Reference Fig.14 and Fig.15 As shown, the first micro switch 18 is arranged in the first mounting groove 123, and the first mounting groove 123 is arranged on one side of the crank center axis 124. After the first micro switch 18 is arranged in the first mounting groove 123, the central control crank 10 is installed on the crank center axis 124, which makes full use of the surplus space inside the central control crank 10 without affecting the normal working stroke of other components, which is conducive to the layout of compact door locks.

[0060] In some embodiments, the first microswitch 18 is provided with a first trigger portion 181, and the first trigger portion 181 elastically extends radially toward the crank center axis 124 of the central control crank 10. The central control crank 10 is configured to gradually press the protrusion 102 against the first microswitch 18 when rotating along a first direction, and the central control crank 10 is configured to separate the first microswitch 18 from the protrusion 102 when rotating along a second direction. The first direction and the second direction are opposite.

[0061] In practice, the central control crank 10 rotates in the first direction. Figure 1 The counterclockwise rotation of the central control crank 10 is Figure 1 Clockwise rotation; combined Figure 5 and Fig.14 As shown, after the first micro switch 18 is partially stuck in the first mounting groove 123, the first trigger portion 181 of the first micro switch 18 extends along the first movable opening 1232 and contacts or moves away from the protruding portion 102 of the central control crank 10, so that the position of the central control crank 10 can be better determined by the first micro switch 18.

[0062] Specifically, when the first micro switch 18 is clamped in the first mounting groove 123, the first micro switch 18 moves along Fig.14The first micro switch 18 is clamped in the first mounting groove 123 in the direction perpendicular to the paper surface and facing inward, and the first micro switch 18 is limited by the third limiting surface 1231 to ensure the stability of the position of the first micro switch 18, thereby making it easier to detect whether the first micro switch 18 is in contact with or separated from the central control crank 10.

[0063] It should be noted that the embodiment of the present invention Fig.14 and Fig.15 It is the door lock housing 12 before the central control crank 10 , the child lock worm gear 9 , the second micro switch 15 , the third micro switch 16 and the first micro switch 18 are installed.

[0064] In some embodiments, the door lock assembly 100 also includes a child lock worm gear 9, the inner opening component includes an inner opening clutch rod 8, an inner opening rocker arm 7 and an inner opening lever 6, the inner opening clutch rod 8 is movably connected to the inner opening rocker arm 7 and the inner opening clutch rod 8 has a child lock on position and a child lock off position, the child lock worm gear 9 is used to drive the inner opening clutch rod 8 to switch between the child lock on position and the child lock off position, the inner opening rocker arm 7 is suitable for pushing the inner opening clutch rod 8 to drive the inner opening lever 6 to unlock the vehicle door when the inner opening clutch rod 8 is in the child lock off position, and when the inner opening clutch rod 8 is in the child lock on position, it is staggered with the inner opening lever 6 along the movement trajectory of the inner opening rocker arm 7.

[0065] In practice, the inner opening lever 6 is used as a structure for rotating the door, and other structures can be used to apply force to the inner opening lever 6 to rotate the inner opening lever 6 to unlock; when the child lock worm gear 9 drives the inner opening clutch lever 8 to switch to the child lock closing position, that is, one end of the inner opening clutch lever 8 contacts the inner opening lever 6 so that the inner opening lever 6 can rotate to unlock, and by applying force to the inner opening rocker arm 7, the inner opening rocker arm 7 drives the inner opening clutch lever 8 to move and then drives the inner opening lever 6 to rotate to unlock. On the contrary, when the child lock worm gear 9 drives the inner opening clutch lever 8 to move to separate from the inner opening lever 6, the inner opening clutch lever 8 does not contact the inner opening lever 6, so that the inner opening clutch lever 8 cannot drive the inner opening lever 6 to rotate, that is, the child lock is locked.

[0066] Specifically, refer to Figure 1 , Figure 7 and Figure 8As shown, the inner opening rocker arm 7 includes an active area 74, one end of the inner opening clutch rod 8 is movably connected to the active area 74, and the inner opening clutch rod 8 moves along the direction in which the active area 74 extends so as to make one end of the inner opening clutch rod 8 move away from or close to the inner opening lever 6; in addition, the inner opening lever 6 includes a first pushing portion 64, and the inner opening clutch rod 8 includes a clutch limiting portion 81. When the inner opening clutch rod 8 moves to contact with the fifth contact portion 71 of the inner opening rocker arm 7, that is, the clutch limiting portion 81 of the inner opening clutch rod 8 and the inner opening rocker arm 7 are in contact. The fifth contact portion 71 is in contact, and at the same time, the clutch limit portion 81 of the inner opening clutch rod 8 is also in contact with the bottom of the first pushing portion 64 of the inner opening lever 6. When the inner opening rocker arm 7 is pulled, if the second connecting portion 73 of the inner opening rocker arm 7 is connected to the inner opening pull wire 11, the inner opening pull wire 11 pulls the inner opening rocker arm 7, and then the inner opening clutch rod 8 pushes the first pushing portion 64 and rotates the inner opening lever 6 to unlock; on the contrary, when the child lock is locked, the clutch limit portion 81 of the inner opening clutch rod 8 is also away from the first pushing portion 64 of the inner opening lever 6.

[0067] Furthermore, one way to move the inner opening clutch rod 8 closer to the inner opening lever 6 or farther away from the inner opening lever 6 is to rotate the child lock worm gear 9. For example, the child lock worm gear 9 is movably connected to the inner opening clutch rod 8. Figure 1 When the child lock worm gear 9 rotates clockwise, the clutch limiting portion 81 of the inner opening clutch rod 8 is driven to move away from the first pushing portion 64 of the inner opening lever 6, that is, the child lock is in the on state; and when the child lock worm gear 9 rotates clockwise, the clutch limiting portion 81 of the inner opening clutch rod 8 is driven to move close to the first pushing portion 64 of the inner opening lever 6, that is, the child lock is in the unlocked state.

[0068] In some embodiments, the door lock assembly 100 also includes a second micro switch 15, and the child lock worm gear 9 is suitable for pressing against the second micro switch 15 when the inner opening clutch rod 8 is pushed to switch to the child lock opening position, and separating from the second micro switch 15 when the inner opening clutch rod 8 is pushed to switch to the child lock closing position.

[0069] In practice, by setting the second micro switch 15, when the child lock worm gear 9 rotates, the inner opening clutch rod 8 and the inner opening lever 6 can be judged to be in contact or away from each other by whether the child lock worm gear 9 and the second micro switch 15 are in contact, thereby judging whether the child lock is turned on or off; that is, when the child lock function is turned off, Figure 1 When the child lock function is turned on, the child lock worm gear 9 is rotated counterclockwise to make the child lock worm gear 9 contact with the second microswitch 15 and the inner opening clutch rod 8 is moved away from the inner opening lever 6 to open the child lock. Therefore, by setting the second microswitch 15 to directly judge the rotation of the child lock worm gear 9, the reliability and stability of the child lock can be more accurately judged.

[0070] In some embodiments, the child lock worm gear 9 is provided with a pressing inclined surface 93, and the door lock housing 12 is provided with a second mounting groove 121, the second mounting groove 121 is opened radially outward along the child lock worm gear 9 to form a second active opening 1212, and the second micro switch 15 is installed in the second mounting groove 121 and extends from the second active opening 1212 to press against the pressing inclined surface 93.

[0071] Can be combined Figure 4 , Figure 5 and Fig.15 As shown, Figure 4 The middle child lock worm wheel 9 has a pressing inclined surface 93. Figure 5 and Figure 1 The opposite perspective, when Figure 1 When it is positive, Figure 5 is the rear view, and Fig.15 There is a second mounting groove 121 directly disposed in the door lock housing 12, and the second micro switch 15 is installed in the second mounting groove 121. Fig.15 The child lock central shaft 127 is used to install the child lock worm gear 9, and the second installation groove 121 is located at the child lock worm gear 9. Figure 1 From the rear perspective, the installation of the second micro switch 15 can save space in the door lock housing 12 along the radial direction of the child lock worm gear 9, so that the position arrangement of the second micro switch 15 and the child lock worm gear 9 is more concentrated; and the child lock worm gear 9 is provided with a pressing slope 93, and a part of the second micro switch 15 extends out from the second active opening 1212, so that the child lock worm gear 9 gradually rotates and gradually contacts with the second micro switch 15 better.

[0072] In addition, the second micro switch 15 is arranged in the second installation groove 121. When the child lock is unlocked and locked, the probability of the door lock mechanism colliding with the second micro switch 15 during movement can be greatly reduced, and the stability of the installation and positioning of the second micro switch 15 can be improved. The layout is compact in structure, occupies less door lock space, and can achieve the characteristics of accurate positioning and easy installation.

[0073] In some embodiments, the second microswitch 15 is provided with a second trigger portion 151, which elastically extends outward along the radial direction of the child lock worm gear 9. The child lock worm gear 9 is configured so that the pressing slope 93 gradually presses against the second trigger portion 151 when rotating along a first direction. The child lock worm gear 9 is configured so that the second trigger portion 151 gradually separates from the pressing slope 93 when rotating along a second direction. The first direction is opposite to the second direction.

[0074] That is to say, the child lock worm gear 9 is installed on the child lock center axis 127, and the child lock center axis 127 is installed on the door lock housing 12. When the second micro switch 15 is installed in the second mounting groove 121, the second trigger part 151 of the second micro switch 15 extends out in the radial direction of the child lock center axis 127 away from the child lock center axis 127. When the second micro switch 15 is installed in the second mounting groove 121 and the second trigger part 151 extends out of the second mounting groove 121, it can ensure that the second micro switch 15 is reliably installed while facilitating the contact between the second micro switch 15 and the child lock worm gear 9.

[0075] Specifically, the child lock worm wheel 9 is configured to gradually press the pressing inclined surface 93 against the second triggering portion 151 when rotating in the first direction, that is, Figure 1 The child lock worm wheel 9 rotates counterclockwise, and the pressing inclined surface 93 of the child lock worm wheel 9 presses against the second triggering portion 151. The first direction is the counterclockwise direction, and the child lock worm wheel 9 is configured to rotate in the second direction. The pressing inclined surface 93 is separated from the second triggering portion 151. The second direction is Figure 1 the second trigger portion 151 can be used to detect the position of the child lock worm gear 9, so as to determine whether the child lock worm gear 9 drives the inner opening clutch rod 8 away from or close to the inner opening lever 6 to determine whether the child lock is opened or closed.

[0076] In some embodiments, the second mounting groove 121 forms a plurality of first limit surfaces 1211 , the second micro switch 15 is inserted into the second mounting groove 121 and is engaged and limited with the plurality of first limit surfaces 1211 , and the insertion direction of the second micro switch 15 intersects with the radial direction of the child lock worm gear 9 .

[0077] Reference Fig.15 As shown, when the second micro switch 15 is installed in the second installation groove 121, it can be installed along Fig.15 The second micro switch 15 is inserted in the direction perpendicular to the paper surface toward the inside, and the second trigger part 151 of the second micro switch 15 extends out along the second movable opening 1212. Firstly, the second trigger part 151 is smaller than the structure of the second micro switch 15 installed in the second mounting groove 121, and the second trigger part 151 is easier to extend out along the second movable opening 1212; at the same time, when the second micro switch 15 is installed in the second mounting groove 121, the multiple first limiting surfaces 1211 can limit the second micro switch 15, which can prevent the second micro switch 15 from moving in the radial direction of the child lock. At the same time, the second micro switch 15 can be limited in multiple directions by the second mounting groove 121.

[0078] Specifically, the plugging direction of the second micro switch 15 is Fig.15 In the direction perpendicular to the paper plane facing inward, the radial direction of the child lock worm wheel 9 is Fig.15The radial direction of the central axis 127 of the child lock can facilitate the installation of the second micro switch 15 by limiting the plug-in direction of the second micro switch 15. At the same time, multiple first limit surfaces 1211 can be set to limit the radial movement of the second micro switch 15 along the child lock worm gear 9, thereby ensuring the stability of the position of the second micro switch 15, thereby ensuring the accuracy of the inner opening clutch rod 8 when the child lock worm gear 9 rotates and approaches the second micro switch 15 or moves away from the second micro switch 15.

[0079] In some embodiments, the door lock assembly 100 also includes a third microswitch 16 and a torsion spring 17. The inner opening clutch rod 8 has an inner opening upper safety position and an inner opening unlocked safety position. The inner opening upper safety position corresponds to the child lock opening position, and the inner opening unlocked safety position corresponds to the child lock closing position. The torsion spring 17 is connected between the inner opening clutch rod 8 and the door lock housing 12. The third microswitch 16 is installed on the door lock housing 12. The third microswitch 16 is suitable for pressing against the torsion spring 17 when the inner opening clutch rod 8 is switched to the inner opening upper safety position, and is separated from the torsion spring 17 when the inner opening clutch rod 8 is switched to the inner opening unlocked safety position.

[0080] In practice, the third micro switch 16 can also detect the state of the inner opening safety on or safety off. The inner opening safety on position corresponds to the child lock on position, and the inner opening safety off position corresponds to the child lock off position. For example, one end of the torsion spring 17 is connected to the door lock housing 12 and the other end is connected to the connecting hole 82 at the end of the inner opening clutch rod 8. When the child lock worm gear 9 is moved along Figure 1 When the child lock is in the safety state, the position of the inner opening clutch rod 8 can be directly judged by the third microswitch 16. When the second microswitch 15 is in contact with the child lock worm gear 9 and the third microswitch 16 is in contact with the torsion spring 17, it can be accurately judged that the rotation of the child lock worm gear 9 will drive the inner opening clutch rod 8 away from the inner opening lever 6, that is, the child lock must be in the locked state, thereby further ensuring the accuracy of the locked state detection.

[0081] Of course, the central control crank 10 can also drive the push column 84 of the inner opening clutch rod 8 to move, so that the inner opening clutch rod 8 can switch between the safety state and the release state on the inner opening assembly. Figure 1When the inner clutch rod 8 is rotated counterclockwise, the lever portion 103 pushes the push column 84 of the inner clutch rod 8 to move, thereby causing the clutch limit portion 81 of the inner clutch rod 8 to move away from the inner clutch lever 6. At this time, the central control worm gear 1 controls the inner clutch rod 8 to move away from the inner clutch lever 6 by controlling the central control crank 10; and the central control crank 10 moves along the Figure 1 When the inner opening clutch rod 8 rotates clockwise, one end of the inner opening clutch rod 8 contacts the inner opening lever 6 under the elastic force of the torsion spring 17, thereby releasing the insurance of the inner opening assembly.

[0082] That is to say, the contact between the torsion spring 17 and the third microswitch 16 determines that the inner opening clutch rod 8 is away from the inner opening lever 6. When the movement of the inner opening clutch rod 8 is controlled by the central control crank 10, the inner opening clutch rod 8 is away from the inner opening lever 6 and is in the insurance state of the inner opening component. The inner opening clutch rod 8 contacts the inner opening lever 6 and is in the unlocked state of the inner opening component.

[0083] In some embodiments, the door lock housing 12 is provided with a third mounting groove 122, which opens radially inward along the child lock worm gear 9 to form a third active opening 1222, and the third micro switch 16 is installed in the third mounting groove 122 and at least partially extends from the third active opening 1222 to press against the torsion spring 17.

[0084] Continue to refer to Figure 1 , Figure 5 , Fig.11 and Fig.15 As shown, the third mounting groove 122 opens inwardly along the radial direction of the child lock worm wheel 9 to form a third movable opening 1222, and the third micro switch 16 is moved along the Fig.15 The third micro switch 16 is placed in the third mounting groove 122 in the direction perpendicular to the paper surface and facing inward, and a portion of the third micro switch 16 extends through the third movable opening 1222 and toward one side of the child lock center axis 127. When the inner opening clutch rod 8 approaches the third micro switch 16, it can drive the torsion spring 17 to contact the portion of the third micro switch 16 extending out of the third movable opening 1222.

[0085] Furthermore, the third mounting groove 122 is provided with a second limiting surface 1221, which can limit the third micro switch 16 when the third micro switch 16 is installed in the third mounting groove 122, thereby preventing the third micro switch 16 from being displaced toward one side of the torsion spring 17, thereby ensuring the accuracy of the torsion spring 17 contacting the third micro switch 16 when the inner opening clutch rod 8 moves.

[0086] In some embodiments, the door lock housing 12 is also provided with a movable groove 125, and the inner opening clutch rod 8 is provided with a connecting column 83, which extends into the movable groove 125, and the child lock worm gear 9 is suitable for driving the inner opening clutch rod 8 to move by pushing the connecting column 83 when rotating; wherein, one end of the torsion spring 17 is connected to the door lock housing 12 and the other end extends into the movable groove 125 to be connected to the connecting column 83, and the connecting column 83 is suitable for driving the torsion spring 17 to approach or move away from the third micro switch 16.

[0087] In practice, combined Figure 1 , Figure 4 , Fig.11 and Fig.15 As shown, the child lock worm wheel 9 is provided with an escape opening 94. Fig.15 The middle door lock housing 12 is provided with a movable groove 125, the avoidance opening 94 is opposite to the movable groove 125, and the length of the avoidance opening 94 is smaller than the length of the movable groove 125, one end of the torsion spring 17 is connected to the connecting column 83 of the inner opening clutch rod 8 and the connecting column 83 moves in the movable groove 125, and at the same time, the avoidance opening 94 of the child lock worm gear 9 is opposite to the movable groove 125, that is to say, the movable range of the inner opening clutch rod 8 is along the range of the avoidance opening 94.

[0088] The escape opening 94 of the child lock worm wheel 9 has a first contact surface 91 and a second contact surface 92. When the child lock worm wheel 9 rotates, the first contact surface 91 contacts the connecting column 83 and drives the connecting column 83 to move in the movable groove 125, thereby causing the child lock worm wheel 9 to rotate along the movable groove 125. Figure 1 The clockwise rotation drives the inner opening clutch rod 8 to move and approach the inner opening lever 6, and the child lock worm gear 9 rotates counterclockwise along the Figure 1 The inner opening clutch rod 8 is rotated and driven to move away from the inner opening lever 6.

[0089] Therefore, connecting the torsion spring 17 at the connecting column 83 and the door lock housing 12 can facilitate the contact and distance between the torsion spring 17 and the third microswitch 16, while saving more space; the child lock worm gear 9 is provided with an avoidance opening 94 and a movable groove 125 facing each other, so that the rotation of the child lock worm gear 9 can drive the movement of the inner opening clutch rod 8; and when the child lock worm gear 9 no longer rotates, the inner opening clutch rod 8 can also be moved left and right along the avoidance opening 94 of the child lock worm gear 9 by other means to make the inner opening clutch rod 8 and the inner opening lever 6 move away from each other.

[0090] Specifically, the torsion spring 17 includes a first positioning portion 171, a body portion 172, and a second positioning portion 173. The first positioning portion 171 is connected and installed at the connecting hole 82 of the inner opening clutch rod 8, and the second positioning portion 173 is installed at Fig.15At the positioning and connecting hole 126 of the middle door lock housing 12, the inner opening clutch rod 8 is provided with a hollow connecting column 83, and the first positioning portion 171 is connected to the connecting hole 82 in the connecting column 83, which can limit one end of the torsion spring 17 to prevent the torsion spring 17 from producing a large displacement when approaching or moving away from the third microswitch 16, that is, when the inner opening clutch rod 8 is close to the third microswitch 16, the main body 172 of the torsion spring 17 is in direct contact with the third microswitch 16.

[0091] Therefore, by setting the triggering mode of the torsion spring 17 and the third microswitch 16, there is no need for the third microswitch 16 and the inner opening clutch rod 8 to be in the same plane, which can save the space of the door lock housing 12, and the required measuring area is smaller, with the advantages of compact structure and high space utilization; it is suitable for use in a relatively small space, when the lateral space of the object to be measured is small and the longitudinal space is large, and the torsion spring 17 is innovatively used to build the contact area, which expands the detection space and application scenarios for the third microswitch 16, and the setting of the torsion spring 17 makes the movement of the inner opening clutch rod 8 smoother, thereby making the detection smoother.

[0092] In some embodiments, the second micro switch 15 and the third micro switch 16 are spaced apart and distributed along the circumference of the child lock central axis 127 of the child lock worm gear 9 .

[0093] In practice, refer to Fig.15 As shown, the second microswitch 15 is located in the second mounting groove 121, the third microswitch 16 is located in the third mounting groove 122, and the second mounting groove 121 and the third mounting groove 122 are spaced apart and distributed along the axial direction of the child lock center axis 127, and can contact or move away from the second microswitch 15 when the child lock worm gear 9 rotates, and the rotation of the child lock worm gear 9 drives the inner opening clutch rod 8 to move, so that the movement of the inner opening clutch rod 8 drives the torsion spring 17 to contact or move away from the third microswitch 16, that is, the second microswitch 15 and the third microswitch 16 are both related to the child lock worm gear 9 and the inner opening clutch rod 8, thus, the second microswitch 15 and the third microswitch 16 are arranged around the child lock center axis 127 of the child lock worm gear 9, and the structure of the second microswitch 15, the third microswitch 16 and the child lock worm gear 9 is more compact and saves more space.

[0094] In some embodiments, the outer opening component includes a pawl 4 and a pawl slider 3, the pawl 4 is rotatably mounted on the door lock housing 12, the pawl slider 3 is movably mounted on the pawl 4 and rotates with the pawl 4, the pawl slider 3 is suitable for pushing the inner opening lever 6 when the safety is released, and the rotation trajectory of the pawl slider 3 around the rotation axis of the pawl 4 when the safety is on is staggered with the inner opening lever 6.

[0095] In practice, refer to Figure 1As shown, the pawl slider 3 is provided with a guide opening 31, the pawl 4 is connected to a guide column 32, the pawl slider 3 is provided with a fixed boss 34, and a spring (not shown in the figure) is sleeved on the fixed boss 34, one end of the spring is connected to the pawl slider 3 and the other end is connected to the guide column 32, and the pawl slider 3 is provided with a pushing surface 33, when the central control worm gear 1 controls the central control connecting rod 2 to move toward Figure 1 When the worm gear 1 controls the central control link 2 to move to the right side, the pawl slider 3 moves toward the top of the central control link 2 under the action of the spring, so that the pushing surface 33 of the pawl slider 3 contacts the second pushing portion 63 of the inner opening lever 6. The pawl 4 and the pawl slider 3 are an outer opening component, that is, when the pushing surface 33 of the pawl slider 3 contacts the second pushing portion 63 of the inner opening lever 6, the inner opening lever 6 can be pushed to rotate and unlock; when the central control worm gear 1 controls the central control link 2 to move toward Figure 1 When the pawl slider 3 moves to the left side, it is pressed by the pressing portion 24 of the central control link 2 and moves toward Figure 1 The pawl 4 and the pawl slider 3 move downward, so that the pushing surface 33 of the pawl slider 3 is away from the second pushing portion 63 of the inner opening lever 6. The pawl 4 and the pawl slider 3 cannot contact the inner opening lever 6, and cannot push the inner opening lever 6 to rotate and unlock. At this time, the outer opening is in the upper insurance state.

[0096] That is to say, through the pawl 4 and the pawl slider 3 and the spring arranged therebetween, the pushing surface 33 of the pawl slider 3 can be brought into contact with the second pushing portion 63 of the inner opening lever 6 when the central control link 2 moves toward the right, and the pushing surface 33 of the pawl slider 3 can be separated from the second pushing portion 63 of the inner opening lever 6 when the central control link 2 moves toward the left.

[0097] Specifically, when unlocking, the rotation angle of the inner open lever 6 can be achieved by the second limit block 14 on the central control worm gear 1, and the third side surface 141 contacts the third contact portion 61 of the inner open lever 6 or the fourth side surface 142 contacts the fourth contact portion 62 of the inner open lever 6 to achieve the rotation limitation of the inner open lever 6.

[0098] The embodiment of the utility model also discloses a vehicle. By setting three micro switches, the position arrangement of the first micro switch 18, the second micro switch 15, and the third micro switch 16 can respectively realize accurate monitoring of the position area of ​​the central control crank 10, the child lock worm gear 9, and the inner opening clutch rod 8, and then accurately judge whether the door lock is in the insurance state or the insurance release state, thereby ensuring the safety and effectiveness of the use of the door lock assembly 100 and enhancing the user experience. At the same time, this arrangement makes the door lock assembly 100 compact in structure and occupies less door lock space, which can achieve accurate positioning and simple installation.
