[0042] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the accompanying drawings to specifically illustrate the novel automobile door lock structure of the present invention.

[0043] like Figure 1 、 Figure 2 As shown, the novel automobile door lock structure 100 is used for an upper door lock in a door lock system of a vehicle door without a center frame.

[0044] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 11As shown, the novel automobile door lock structure 100 includes: a housing, a lock tongue 102, a first reset member 103, a pawl 104, an unlocking cable 105, a second reset member 106, a locking member 107, a suction cable 108, a third reset member 109, an ice-breaking member 112 and a fourth reset member 113.

[0045] In this embodiment, the housing includes a bottom plate 1011 and a fixing plate 1012, and the bottom plate 1011 is mounted on the fixing plate 1012. The fixing plate 1012 is mainly used to install the new automobile door lock structure 100 on the automobile door. The location and number of mounting holes on the fixing plate 1012 can be flexibly configured according to customer needs. In this embodiment, Figure 6 Four installation forms of the fixing plate 1012 are given. Of course, the fixing plate 1012 is not limited to Figure 6 Four forms are shown.

[0046] The lock tongue 102 is rotatably mounted on the bottom plate 1011 . The lock tongue 102 is provided with a first meshing tooth 1021 , a second meshing tooth 1022 , a suction and activation member 1024 and an ice-breaking activation member 1025 .

[0047] The two ends of the first reset member 103 are respectively restricted by the lock tongue 102 and the fixed plate 1012, and after the lock tongue 102 rotates, a restoring force is generated on the lock tongue 102. Specifically, the first reset member 103 is a torsion spring, and the two ends of the first reset member 103 are respectively installed on the lock tongue 102 and the fixed plate 1012.

[0048] The pawl 104 is rotatably mounted on the base plate 1011 and cooperates with the lock tongue 102. The pawl 104 is provided with a third meshing tooth 1041, which meshes with the first meshing tooth 1021 when the lock tongue 102 is in a fully locked state; the third meshing tooth 1041 meshes with the second meshing tooth 1022 when the lock tongue 102 is in a half-locked state.

[0049] The unlocking cable 105 is connected to the pawl 104 and the intermediate actuator 200. The unlocking cable 105 is used to pull the pawl 104 to rotate. The intermediate actuator 200 can pull the unlocking cable 105, thereby rotating the pawl 104. Specifically, the unlocking cable 105 is a cable structure, including the cable 105 and a first cable sleeve 1051. The cable 105 passes through the first cable sleeve 1051, which is mounted on the base plate 1011. The unlocking cable 105 can be manually controlled by the opening handle or automatically controlled by the intermediate actuator 200.

[0050] The two ends of the second reset member 106 are respectively restricted by the pawl 104 and the fixed plate 1012. After the pawl 104 rotates, a restoring force is generated on the pawl 104. Specifically, the second reset member 106 is a torsion spring, and the two ends of the second reset member 106 are respectively mounted on the pawl 104 and the fixed plate 1012.

[0051] The lock tongue 102, the first reset component 103, the pawl 104 and the second reset component 106 cooperate so that when the pawl 104 is not pulled by the unlocking wire 108, the lock tongue 102 and the pawl 104 are always in contact, the second reset component 106 is always in a compressed state, and when the lock tongue 102 is in the fully open state, the first reset component 103 is in a non-compressed state.

[0052] The locking member 107 is slidably mounted on the base plate 1011 and cooperates with the suction-pushing member 1024. The locking member 107 is used to pull the lock tongue 102 to rotate and lock the lock tongue 102.

[0053] Specifically, the locking member 107 is "L" shaped, and the L-shaped horizontal side of the locking member 107 cooperates with the suction and toggling member 1024. The bottom plate 1011 is provided with a limiting side wall 1014 and a second limiting member 1015 parallel to the L-shaped vertical side of the locking member 107. The L-shaped vertical side of the locking member 107 is sandwiched between the second limiting member 1015 and the limiting side wall 1014. The second limiting member 1015 and the limiting side wall 107 limit the sliding trajectory of the locking member 107. Figure 5 When viewed from the direction of the lock, the locking member 107 slides to the right, and the L-shaped horizontal edge of the locking member 107 drives the suction and driving member 1024 of the lock tongue 102 to rotate the lock tongue 102 clockwise, thereby locking the lock tongue. More specifically, the relationship between the locking member 107 and the suction and driving member 1024 on the lock tongue 102 satisfies: Figure 8 From the direction of view, when the lock tongue 102 is in the fully open state, the locking member 107 moves to the right without moving the suction and toggling member 1024. When the lock tongue is in the semi-locked state, the locking member 107 moves to the right and toggles the suction and toggling member 1024 to make the lock tongue 102 rotate clockwise.

[0054] Specifically, if Figure 10 As shown, the suction and driving member 1024 is a cylinder provided on one side of the lock tongue 102. When the locking member 107 moves, the suction and driving member 1024 is pushed, thereby pushing the lock tongue 102 to rotate.

[0055] The pull-in cable 108 is connected to the locking member 107 and the intermediate actuator 200. The pull-in cable 108 is used to pull the locking member 107 to move, thereby rotating the lock tongue 102 and locking the lock tongue 102. The intermediate actuator 200 can pull the pull-in cable 108, thereby pulling the locking member 107 to move. Specifically, the pull-in cable 108 is a cable structure, including the pull-in cable 108 and a second pull-in cable sleeve 1081. The pull-in cable 108 passes through the second pull-in cable sleeve 1081, and the second pull-in cable sleeve 1081 is mounted on the base plate 1011. The pull-in cable 108 can be manually controlled by the opening handle or automatically controlled by the intermediate actuator 200.

[0056] The ends of the third reset member 109 are respectively fixed to the locking member 107 and the fixing plate 1012. Specifically, the first reset member 103 is a tension spring, with its ends respectively attached to the locking member 107 and the fixing plate 1012. The direction of compression of the first reset member 103 is parallel to the direction of movement of the third reset member 109. When the pull wire 108 pulls the locking member 107 toward unlocking, the third reset member 109 is compressed. When the pull wire 108 no longer applies tension, the locking member 107 is reset under the elastic force of the third reset member 109.

[0057] Specifically, a first limiting member 1017 is provided on the bottom plate 1011, and the first limiting member 1017 is used to limit the maximum distance that the locking member 107 slides in the unlocking direction. Figure 5 In the direction shown, the first limiting member 1017 can limit the maximum distance that the locking member 107 slides to the right. This maximum distance makes the lock tongue 102 just completely locked, avoiding the lock member 107 from sliding too far to the right and causing damage to the lock tongue 102 and the suction pull line 108.

[0058] The ice-breaking member 112 is slidably mounted on the bottom plate 1011, and the two ends of the ice-breaking member 112 are respectively matched with the ice-breaking toggle member 1025 and the pawl 104. Figure 11 、 Figure 12 As shown, a sliding hole 1013 is provided on the bottom plate 1011, and the ice-breaking member 112 is slidably mounted on the sliding hole 1013. More specifically, there are two sliding holes 1013, and the two ends of the ice-breaking member 112 are slidably mounted on the two sliding holes 1013 respectively.

[0059] The fourth return member 113 is constrained at both ends by the ice-breaking member 112 and the bottom plate 1011, and generates a restoring force on the ice-breaking member 112 after the ice-breaking member 112 performs ice-breaking sliding. Specifically, the fourth return member 113 is a torsion spring, one end of which is mounted on the bottom plate 1011 and the other end is mounted on the ice-breaking member 112.

[0060] Among them, the ice-breaking member 112, the pawl 104 and the lock tongue 102 meet the following conditions: Figure 13 As shown, before ice breaking is performed, the ice breaking toggle member 1025 does not contact the ice breaking member 112 when the lock tongue 102 rotates, and the pawl 104 does not contact the ice breaking member 112 when it rotates to unlock. When ice breaking is performed, the pawl 104 rotates to disengage the first meshing tooth 1021 and the second meshing tooth 1022, as shown in FIG. Figure 11 、 Figure 12 As shown, the pawl 104 continues to rotate to drive the ice-breaking member 112 to slide, and the sliding of the ice-breaking member 112 drives the lock tongue 102 to rotate, thereby opening the lock tongue 102.

[0061] In this embodiment, the novel automobile door lock structure 100 further includes a first micro switch 110 and a second micro switch 111 .

[0062] The locking tongue 102 is provided with a first pressing member 1023 , and the pawl 104 is provided with a second pressing member 1042 .

[0063] The first micro switch 110 is connected to the controller and cooperates with the second pressing member 1042. When the lock tongue 102 is in the fully open state, the second pressing member 1042 presses the first micro switch 110 to close. In other states, the first micro switch 110 is in the open state.

[0064] The second micro switch 111 is connected to the controller and cooperates with the first pressing member 1023. When the lock tongue 102 is in a semi-locked state, the first pressing member 1023 presses the second micro switch 111 to close. In other states, the second micro switch 111 is in an open state.

[0065] The state of the door lock can be determined based on the closed state of the first micro switch 110 and the second micro switch 111 .

[0066] Specifically, an electronic interface component 1016 is provided on the base plate 1011 , and the wires of the first micro switch 110 and the second micro switch 111 are integrated on the electronic interface component 1016 . The first micro switch 110 and the second micro switch 111 are connected to the controller through the electronic interface component 1016 .

[0067] Working process:

[0068] The process from fully open state to fully locked state:

[0069] When the lock tongue 102 is in the fully open state, Figure 7As shown, the first micro switch 110 is in the closed state and the second micro switch 111 is in the open state. The driver can know that the door lock is in the fully open state based on the on-closed state of the first micro switch 110 and the second micro switch 111. After manually closing the car door, the lock tongue 102 changes from the fully open state to the half-locked state under the force of the door closing.

[0070] When the lock tongue 102 is in a semi-locked state, Figure 8 As shown, the first micro switch 110 is in the open state and the second micro switch 111 is in the closed state. The driver can know that the door lock is in the semi-locked state according to the open and closed states of the first micro switch 110 and the second micro switch 111.

[0071] by Figure 5 From the direction of the lock, the controller controls the transfer actuator 200 or manually pulls the suction wire 108, which pulls the locking member 107 to the right. The locking member 107 pushes the suction toggle member 1024 on the lock tongue 102, thereby pushing the lock tongue 102 to rotate clockwise, and the lock tongue 102 is fully locked. The controller then controls the actuator to stop pulling the suction wire 108, and the locking member 107 moves to the left and resets under the action of the third reset member 109.

[0072] The process from fully locked state to fully open state:

[0073] When the lock tongue 102 is in the fully locked state, Figure 9 As shown, the third meshing tooth 1041 on the pawl 104 is meshed with the first meshing tooth 1021 on the lock tongue 102, and the first micro switch 110 and the second micro switch 111 are both in the off state. Since the first micro switch 110 and the second micro switch 111 are both in the off state, there is no signal feedback, and the driver can know that the door lock is in the fully locked state.

[0074] by Figure 5From the direction of view, the controller controls the transfer actuator 200 or manually pulls the unlocking wire 105, the unlocking wire 105 pulls the pawl 104 to rotate counterclockwise, the third meshing tooth 1041 on the pawl 104 is disengaged from the first meshing tooth 1021 on the lock tongue 102, and the lock tongue 102 rotates clockwise under the action of the first reset member 103, and the third meshing tooth 1041 on the pawl 104 contacts and slides relative to the lock tongue 102 until the third meshing tooth 1041 on the pawl 104 is engaged with the second meshing tooth 1022 on the lock tongue 102, and the lock tongue 102 is in a semi-locked state. After the lock tongue 102 rotates, the first pressing member 1023 presses the second micro switch 111 to close, and the control When the controller receives the closing signal of the second microswitch 111, the driver will know that the door lock is in the half-locked state at this time; the controller controls the transfer actuator 200 or manually pulls the unlocking wire 105 again, and the unlocking wire 105 pulls the pawl 104 to rotate counterclockwise, and the third meshing tooth 1041 on the pawl 104 is disengaged from the second meshing tooth 1022 on the lock tongue 102. The lock tongue 102 rotates clockwise under the action of the first reset member 103 until the lock tongue 102 is fully open. When the lock tongue is fully open, the rotation angle of the pawl 104 just presses the first microswitch 110 to close. The controller receives the closing signal of the first microswitch 110, and the driver will know that the door lock is in the fully open state at this time.

[0075] When the lock tongue 102 is frozen in the locked state, the ice is broken. Figure 11 From the direction shown, the controller controls the transfer actuator 200 or manually pulls the unlocking cable 105, which pulls the pawl 104 counterclockwise. After the pawl 104 rotates counterclockwise to a certain angle, it contacts the ice-breaking member 112. The unlocking cable 105 pulls the pawl 104 to continue to rotate counterclockwise, and the pawl 104 pushes the ice-breaking member 112 to slide rightward. After the ice-breaking member 112 slides rightward for a distance, it contacts the ice-breaking toggle member 1025 on the lock tongue 102. The pawl 104 pushes the ice-breaking member 112 to continue to slide rightward, and the ice-breaking member 112 pushes the lock tongue 102 to rotate counterclockwise until the lock tongue 102 is fully opened. After the lock tongue 102 is fully opened, the pulling of the unlocking cable 105 stops, and the ice-breaking member 112 moves leftward to its initial position under the action of the fourth reset member 113.

[0076] The above embodiments are preferred examples of the present invention and are not intended to limit the scope of protection of the present invention.
