DETAILED DESCRIPTION

[0051] 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.

[0052] Reference below Figure 1-Figure 20 The door lock assembly 100 according to the embodiment of the utility model is described, which has the release and engagement states of the inner opening component and the outer opening component, has good safety performance, and also has an ice-breaking function, and can electrically attract the semi-locked state to the fully locked state to solve the problem of poor sound quality caused by the sealing reaction force. It also has a super lock and replaces the electronic child lock with a mechanical child lock, which can play a role in reducing costs. The super lock function covers the child lock function, and can meet the multi-functional requirements of most high-end car door locks.

[0053] like Figure 1-20 As shown, the door lock assembly 100 of the embodiment of the utility model includes: a locking component, an ice-breaking component 4, an inner opening component, an outer opening component and a safety component.

[0054] Among them, the locking assembly includes a lock tongue 1 and a pawl structure, the lock tongue 1 is used to lock with the lock ring 101 of the vehicle door, and the pawl structure is used to selectively lock the lock tongue 1; the ice-breaking assembly 4 is power-connected to the lock tongue 1, and is used to open or close the lock tongue 1; the inner opening assembly and the outer opening assembly are respectively power-connected to the pawl structure, and are used to drive the pawl structure to unlock the lock tongue 1; the safety assembly is respectively connected to the inner opening assembly and the outer opening assembly, and is used to drive the inner opening assembly and / or the outer opening assembly to switch between the safety state and the safety release state.

[0055] Reference Figure 3 As shown, the lock tongue 1 and the pawl structure are both located on the lock body bottom plate sheet metal 102, and the lock tongue 1 is provided with a first notch 110, a second notch 120 and a third notch 130, wherein when the door is closed, the lock ring 101 of the door is fixed at the position of the first notch 110 of the lock tongue 1, and when the lock tongue 1 is located Figure 3 In the position shown, the pawl structure can extend to the second notch 120 and the third notch 130, that is, the lock tongue 1 is blocked by the pawl structure, and the vehicle door is in a locked state at this time.

[0056] Specifically, when the door is closed, the lock ring 101 is locked from top to bottom, that is, from Figure 4 to Figure 5 , lock tongue 1 turns clockwise, refer to Figure 5 As shown, when the pawl structure first enters the third notch 130 of the lock tongue 1 and does not enter the second notch 120 of the lock tongue 1, the pawl structure and the lock tongue 1 are in a semi-locked state.

[0057] In addition, the ice breaking assembly 4 is connected to the lock tongue 1 by power. First, the ice breaking assembly 4 includes an ice breaking rocker arm 41, an ice breaking pull line 42, an ice pushing arm 43, an ice rocker arm 44 and a snow carrying rod 45. In actual operation, if the door lock reaches Figure 6 When the door is in the semi-locked position, it is not completely locked, and the door sends a semi-locked signal. The controller in the vehicle senses the semi-locked signal of the door, controls the motor of the ice-breaking wire 42 to be started, and drives the ice-breaking wire 42 to rotate, that is, along the Figure 6 The left side of the door lock pulls the ice-breaking wire 42, and the suction rocker arm 44 rotates clockwise, driving the suction push arm 43 to rotate clockwise, so that the suction push arm 43 pushes the lock tongue 1 to overcome the sealing reaction force of the door lock ring 101 to reach the fully locked position, that is, at this time, the door lock is in the fully locked position. Figure 7 Thus, when the vehicle door is in the half-locked position, the vehicle door can be adjusted to the fully locked position by the ice breaking assembly 4, so as to achieve the safety of closing the vehicle door and reduce noise.

[0058] Of course, the ice breaking assembly 4 can also be used for vehicles in extreme weather conditions, such as Figure 8 and Fig. 9As shown, as the ice-sealing force acts under extreme working conditions, when the ratchet structure is moved to the unlocking position, due to the ice-sealing force under extreme working conditions, the lock tongue 1 is frozen and cannot be ejected normally, the vehicle detects that the lock tongue 1 fails to pop out normally, and sends a signal that the lock tongue 1 fails to pop out, then performs an ice-breaking action, rotates the ratchet structure, wherein a snow-carrying rod 45 is hinged on the ratchet structure, and the other end of the snow-carrying rod 45 is dynamically connected to the suction push arm 43. When the ratchet structure is rotated, the snow-carrying rod 45 hinged on its upper end will push the suction push arm 43 while breaking the ice, so that one end of the suction push arm 43 moves to the rocker arm notch 411, Fig. 9 The ice-breaking position is shown. At this time, when the ice-breaking action is performed, the motor controlling the suction and ice-breaking pull wire 42 is started, and the suction and ice-breaking rocker arm 44 is driven to rotate clockwise by pulling the suction and ice-breaking pull wire 42, so as to push the suction push arm 43 and the ice-breaking rocker arm 41 to rotate clockwise, and to push the lock tongue 1 to rotate counterclockwise, so as to complete the ice-breaking action and the lock tongue 1 pops out normally.

[0059] Therefore, the snow-loading rod 45, the suction push arm 43, the suction ice-breaking pull wire 42, the suction rocker arm 44, the ice-breaking rocker arm 41 and other structures of the above-mentioned ice-breaking assembly 4 can realize the action of breaking ice for the door lock under extreme weather conditions. At the same time, the suction ice-breaking pull wire 42, the suction rocker arm 44, and the suction push arm 43 of the above-mentioned ice-breaking assembly 4 can also electrically suction the door lock to the fully locked position when the door lock reaches a half-locked state.

[0060] In addition, the inner opening assembly and the outer opening assembly of the embodiment of the utility model are respectively connected to the pawl structure by power. When the inner opening assembly is driven, the inner opening assembly can drive the pawl structure. Figure 3 The pawl structure rotates counterclockwise, and when the pawl structure disengages from the second notch 120 and the third notch 130 of the lock tongue 1 during the rotation process, the lock tongue 1 pops out, that is, the pawl structure can drive the lock tongue 1 to open, thereby unlocking.

[0061] Of course, when the outer opening component is driven, the outer opening component can also drive the pawl structure to rotate the pawl structure counterclockwise, so that the pawl structure is disengaged from the second notch 120 and the third notch 130 of the lock tongue 1, so that the lock tongue 1 pops out counterclockwise, and the door can also be unlocked. The inner opening component can open the door from the inside of the door, and the outer opening component can open the door from the outside of the door. In practice, when the inner opening component of the door is in the unlocked state, the door can be opened from the inside. Similarly, when the outer opening component of the door is also in the unlocked state, the door can be opened from the outside. The pawl structure is driven by the outer opening component or the inner opening component to drive the lock tongue 1 to unlock, so as to open the door.

[0062] Specifically, the inner opening component of the door can be unlocked or secured, or the outer opening component can be unlocked or secured through the safety component. When the inner opening component of the door is unlocked, the inner opening component can form a direct or indirect power transmission with the ratchet structure, and the inner opening component can be driven to drive the ratchet structure to pop out the lock tongue 1 to unlock; when the inner opening component of the door is secured, the inner opening component does not form a direct or indirect power transmission with the ratchet structure, and the door cannot be opened; similarly, when the outer opening component of the door is secured, the outer opening component does not form a direct or indirect power transmission with the ratchet structure, and the door cannot be opened. Therefore, by setting a safety component for the door lock, the safety of driving can be guaranteed, and the door can be prevented from being accidentally opened during driving, which poses a threat to the safety of the occupants.

[0063] Therefore, the door lock assembly 100 of the embodiment of the utility model has the release and engagement states of the inner opening component and the outer opening component, has good safety performance, and also has an ice-breaking function, and can electrically switch the semi-locked state to a fully locked state to solve the problem of poor sound quality caused by the sealing reaction force.

[0064] In some embodiments, the door lock assembly 100 also includes a locking link 10 and an inner opening crank 6. The locking link 10 is pressed against the outer opening component, and the inner opening crank 6 is connected and cooperated with the inner opening component. The inner opening crank 6 is suitable for driving the inner opening component to switch between the secured state and the disengaged state. The locking link 10 is suitable for driving the outer opening component to switch between the secured state and the disengaged state. The locking link 10 is connected to the inner opening crank 6 and is linked.

[0065] In practice, it can be combined Fig.10 As shown, the locking link 10 is an integrally formed structure, and the locking link 10 is hinged to the inner opening crank 6. At the same time, the locking link 10 is dynamically connected to the outer opening component. When the inner opening crank 6 rotates, it can drive the locking link 10 to move, so that the locking link 10 moves to switch the outer opening component of the door between the secured or unsecured state; similarly, the movement of the inner opening crank 6 can also switch the inner opening component to the unsecured state and the secured state.

[0066] Specifically, the locking link 10 adjusts the outer opening component to a state where it can transmit power to the pawl structure, such as direct or indirect power transmission. At this time, the outer opening component is in the unsecured state, so that when the outer opening component is driven, the pawl structure can be driven to unlock the lock tongue 1. Conversely, the outer opening component can also be adjusted to a state where it cannot transmit power to the pawl structure through the locking link 10, that is, the outer opening component cannot act on the pawl structure to make the pawl structure open the lock tongue 1. At this time, the outer opening component is in the secured state.

[0067] Among them, the adjustment of the locking link 10 can be driven by the inner opening crank 6. When the inner opening crank 6 rotates, the inner opening component can be adjusted to a direct or indirect power transmission mode with the pawl structure, that is, the inner opening component is in a released safety state, or the inner opening component can be adjusted to a state where direct or indirect power transmission with the pawl structure cannot be performed, that is, the power of the inner opening component cannot act on the pawl structure, and at this time, the outer opening component is in a safe state.

[0068] Thus, the state linkage of the inner opening component and the outer opening component is realized through the inner opening crank 6 and the locking link 10, and both the inner opening component and the outer opening component can be switched between the released state and the secured state, and can be switched according to actual user needs. Moreover, the locking link 10 can be designed to conform to the internal space of the door lock cover plate 103, which can effectively save the internal space of the door lock cover plate 103, thereby reducing the overall size of the lock as much as possible.

[0069] In some embodiments, the locking link 10 is configured to drive the outer opening component to switch from the secured state to the unsecured state when moving along a first moving direction, and is configured to drive the outer opening component to switch from the unsecured state to the secured state when moving along a second moving direction, and the first moving direction is opposite to the second moving direction; and / or, the inner opening crank 6 is configured to drive the inner opening component to switch from the secured state to the unsecured state when rotating around a first rotational direction, and is configured to drive the inner opening component to switch from the unsecured state to the secured state when moving around a second rotational direction, and the first rotational direction is opposite to the second rotational direction.

[0070] In practice, the locking link 10 is provided with a pressing portion 1001, and an outward-opening clutch rod 12 is provided below the locking link 10. When the locking link 10 moves toward the left, the outward-opening clutch rod 12 is pressed down by the pressing portion 1001, which is the safety-on state, and when the outward-opening clutch rod 12 moves upward, it is the safety-off state.

[0071] The first moving direction is Fig.10 The second moving direction is Fig.10 When the locking link 10 moves along the left side, the pressing portion 1001 at the lower portion of the locking link 10 can press the outer opening clutch rod 12, causing the outer opening clutch rod 12 to move downward, thereby causing the outer opening clutch rod 12 to move to the upper safety state; the outer opening clutch rod 12 and the door lock cover plate 103 are elastically connected by a spring, and when the outer opening clutch rod 12 is in the above-mentioned upper safety state, the spring between the outer opening clutch rod 12 and the door lock cover plate 103 is squeezed, and when the outer opening assembly needs to switch from the upper safety state to the unlocked safety state, the locking link 10 moves along the left side. Fig.10The outer opening clutch rod 12 moves to the right side, and the outer opening clutch rod 12 is reset upward under the action of the spring force, so that the outer opening clutch rod 12 moves from the on-safety state to the off-safety state; thus, the conversion of the on-safety state and the off-safety state of the outer opening component is realized through the movement of the locking link 10.

[0072] In addition, the first rotation direction is Fig.10 The second rotation direction is clockwise. Fig.10 In the counterclockwise direction, when the inner opening crank 6 is set to rotate around the first rotation direction, the inner opening component can be switched to a state of power transmission with the pawl structure, which is the released safety state, and when the inner opening crank 6 is set to rotate around the second rotation direction, the inner opening component can be switched to a state of no power transmission with the pawl structure, which is the engaged safety state.

[0073] Therefore, when the inner opening component is switched to the unfastened state, it can be achieved by rotating the inner opening crank 6 clockwise, or when the inner opening component is switched to the secured state, it can be achieved by rotating the inner opening crank 6 counterclockwise; when the outer opening component is switched to the unfastened state, it can be achieved by adjusting the locking link 10 to move toward the right while the outer opening clutch rod 12 moves upward due to the action of the spring force; when the outer opening component is switched to the secured state, it can be achieved by adjusting the locking link 10 to move toward the left so that the pressing portion 1001 of the locking link 10 presses the outer opening clutch rod 12 downward.

[0074] In some embodiments, the locking link 10 is configured to rotate the inner crank 6 around a first rotation direction while moving along a first movement direction, and the locking link 10 is configured to rotate the inner crank 6 around a second rotation direction while moving along a second movement direction.

[0075] In practice, the inner crank 6 and the locking link 10 are arranged in a linkage mode, and the inner crank 6 is rotated clockwise by adjusting the locking link 10 to move toward the right, and the inner crank 6 is rotated counterclockwise by adjusting the locking link 10 to move toward the left; or the locking link 10 can be moved toward the right by adjusting the inner crank 6 to rotate clockwise, and the locking link 10 can be moved toward the left by adjusting the inner crank 6 to rotate counterclockwise. The inner crank 6 rotates clockwise and the locking link 10 moves toward the right to be in the unsecured state, and the inner crank 6 rotates counterclockwise and the locking link 10 moves toward the left to be in the secured state.

[0076] That is to say, the outer opening component can be switched to the disarmed state by switching the inner opening component to the disarmed state, and the inner opening component can also be switched to the disarmed state by switching the outer opening component to the disarmed state, or the outer opening component can be switched to the armed state by switching the inner opening component to the armed state, or the inner opening component can be switched to the armed state by switching the outer opening component to the armed state. Different methods can be selected to adjust the armed or disarmed state of the door lock according to actual conditions, with high flexibility.

[0077] In some embodiments, the safety assembly includes a central control worm gear structure 9, which is power-connected to the locking link 10 and is used to drive the locking link 10 to move along the first moving direction.

[0078] In practice, the central control worm gear structure 9 is provided with a first boss 91, and further reference is made to Fig.11 As shown, Fig.11 It is in the insurance state, and the locking link 10 is provided with a limit groove 1002. The left side of the limit groove 1002 is the left contact surface, and the right side of the limit groove 1002 is the right contact surface. Due to the setting of the first boss 91 and the right contact surface of the locking link 10, the movement of the locking link 10 can be controlled by controlling the rotation of the central control worm gear structure 9. If the central control worm gear structure 9 rotates clockwise, the right contact surface contacts the right side of the first boss 91, which can drive the locking link 10 to rotate toward the right.

[0079] Then, the central control worm gear structure 9 rotates clockwise to adjust the locking link 10 to the outer opening assembly to the unlocked state, and drives the inner opening crank 6 to adjust the inner opening assembly to the unlocked state. When the central control worm gear structure 9 rotates clockwise, the locking link 10 moves toward the right side to switch the outer opening clutch rod 12 to a state where power can be indirectly transmitted with the ratchet structure, that is, the unlocked state. Therefore, the door lock can be switched to the unlocked state through the central control worm gear structure 9.

[0080] In addition, the central control worm gear structure 9 is powered by the central control motor and the worm 24, which can drive the rotation of the central control worm gear structure 9 more concisely. The electric safety release is achieved by driving the central control motor and the worm 24 to drive the central control worm gear structure 9 to rotate clockwise. The first boss 91 on the central control worm gear structure 9 drives the locking link 10 to move right to the safety release position. When the central control worm gear structure 9 switches the inner opening component and the outer opening component to the safety release state, the automation is high and the efficiency is higher.

[0081] In some embodiments, the safety assembly includes a mechanical lock structure 16, which is dynamically connected to the locking link 10 and is used to drive the locking link 10 to move along the first moving direction or along the second moving direction.

[0082] In practice, one end of the locking link 10 is hinged to the mechanical lock structure 16, and the other end is hinged to the inner crank 6. At the same time, the bottom of the locking link 10 is abutted against the outer clutch rod 12 through the pressing part 1001. The mechanical insurance or release operation can be achieved by rotating clockwise or counterclockwise.

[0083] When the mechanical lock structure 16 is manually secured, refer to Fig.10 As shown, the mechanical lock structure 16 will rotate counterclockwise to push the locking link 10 to move to the left side. In the process of moving toward the left side, the locking link 10 will cause the outer opening clutch rod 12 to move downward, thereby changing the position of the outer opening clutch rod 12, so that the outer opening clutch rod 12 is converted into a state where power cannot be transmitted to the ratchet structure, that is, the outer opening component is in the secured state. At the same time, in the process of moving the locking link 10 toward the left side, the inner opening crank 6 also rotates counterclockwise, and the inner opening crank 6 switches the inner opening component to a state where power cannot be transmitted to the ratchet structure, that is, the secured state.

[0084] Reference Fig.11 When the mechanical lock structure 16 rotates clockwise, the locking link 10 can be moved toward the right side, so that the outer clutch rod 12 moves upward under the elastic force of the elastic member, so that the outer clutch rod 12 is switched to a position where power can be transmitted with the ratchet structure, and the outer opening component can be released. Similarly, when the locking link 10 moves toward the right side, the inner crank 6 rotates clockwise, and the inner crank 6 switches the inner opening component to a state where power can be transmitted with the pawl structure, that is, the release state. Therefore, by setting the mechanical lock structure 16 to achieve mechanical insurance and release actions, it can be used as a backup to deal with the situation where the electric insurance or release cannot be applied or released in an emergency.

[0085] In some embodiments, the safety assembly includes a super lock structure, which is dynamically connected to the inner crank 6 and is used to drive the inner crank 6 to rotate around the second rotation direction.

[0086] In practice, if Fig.18As shown, the super lock structure includes a super lock worm gear 13, which can be driven by a super lock motor worm gear 22. When the super lock worm gear 13 is driven by the super lock motor worm gear 22, it drives the inner opening crank 6 to rotate, and the rotation of the inner opening crank 6 can adjust the unlocked state and the secured state of the inner opening component. For example, when the super lock motor worm gear 22 is started, it drives the super lock worm gear 13 to rotate counterclockwise to the position shown in the figure and remains stationary, then the inner opening crank 6 will be forced to rotate in the counterclockwise direction, that is, the second rotation direction is the counterclockwise rotation direction. At this time, the counterclockwise rotation of the inner opening crank 6 can put both the inner opening component and the outer opening component in the secured position, and the inner opening component and the outer opening component can also be switched to the secured position through the super lock structure, so that there are more ways to secure the inner opening component and the outer opening component.

[0087] In some embodiments, the super lock structure also includes a super lock clutch rod 20, and the inner opening component includes an inner opening pull wire 11. The inner opening pull wire 11 is configured to push the super lock clutch rod 20 to move when pulled once and enable the super lock clutch rod 20 to drive the inner opening crank 6 to switch the inner opening component to the unblocked state. The inner opening pull wire 11 is configured to drive the pawl structure to move through the inner opening crank 6 after a second pull.

[0088] In practice, continue to refer to Fig.18 As shown, one end of the super lock clutch rod 20 is hinged to the super lock worm gear 13, and the other end is movably connected to the inner opening assembly. When the inner opening pull wire 11 is pulled upward, the super lock clutch rod 20 is pushed upward. Fig.17 As shown, the super lock clutch rod 20 is provided with a third boss 201, and the inner crank 6 is provided with a third push portion 61. Fig.18 When pulled upward, the inner opening crank 6 can rotate counterclockwise, and the inner opening component is switched to the released state. That is to say, the inner opening component can realize power transmission with the pawl structure, and then continue to pull the inner opening pull wire 11 upward, so that the inner opening component can directly or indirectly drive the pawl structure to rotate, and the rotation of the pawl structure can realize the disengagement between the pawl structure and the second notch 120 and the third notch 130 of the lock tongue 1, so that the lock tongue 1 is unlocked, which can ensure the safety of the occupants in the vehicle in an emergency condition and ensure internal unlocking. The inner opening pull wire 11 is set to be pulled twice to realize the opening of the door lock, and the door lock is more secure when closed.

[0089] In some embodiments, the inner opening component includes an inner opening rocker arm 8 and an inner opening clutch rod 14, the inner opening clutch rod 14 is movably connected to the inner opening rocker arm 8, and the inner opening crank 6 is suitable for driving the inner opening clutch rod 14 to move between the upper safety position and the unsafe position; the inner opening rocker arm 8 is suitable for pushing the inner opening clutch rod 14 to drive the pawl structure to move when the inner opening clutch rod 14 is in the unsafe position, and the inner opening rocker arm 8 has no power output when the inner opening clutch rod 14 is in the upper safety position.

[0090] Specifically, Fig.10 As shown, the inner opening rocker arm 8 is provided with a first slide slot 81 and a second slide slot 82, wherein one end of the inner opening clutch rod 14 is movably connected in the first slide slot 81, and a torsion spring 15 is provided between the other end of the inner opening clutch rod 14 and the cover plate 103. Fig.10 The back of the inner opening clutch rod 14 is also provided with a connecting column 141 (see Fig.17 ), the inner opening clutch rod 14 can be moved when the inner opening crank 6 rotates. When one end of the inner opening clutch rod 14 moves to the left side of the first slide slot 81, the inner opening clutch rod 14 and the ratchet structure can achieve power transmission, that is, the inner opening safety is released, and when the inner opening clutch rod 14 is away from the left side of the first slide slot 81, that is, the position where the inner opening clutch rod 14 and the ratchet structure cannot achieve power transmission, that is, the inner opening safety is on.

[0091] Furthermore, the inner crank 6 has a fourth pushing portion 62, and the fourth pushing portion 62 is located Fig.10 When the inner crank 6 rotates counterclockwise, the fourth push portion 62 of the inner crank 6 can push the connecting column 141 of the inner clutch rod 14, so that the inner clutch rod 14 is away from the left side of the first slide groove 81 of the inner rocker arm 8, and the inner clutch rod 14 cannot achieve power transmission with the pawl structure, that is, the safety state, at this time, the torsion spring 15 connected to the inner clutch rod 14 is compressed; and when the inner crank 6 rotates clockwise, the inner clutch rod 14 is reset under the action of the torsion spring 15, and the left end of the inner clutch rod 14 moves to the left side of the first slide groove 81 of the inner rocker arm 8. At this time, the inner clutch rod 14 can achieve power transmission with the pawl structure, which is the safety release state.

[0092] In addition, the inner crank 6 also has a third pushing portion 61, which is combined with Fig.17 and Fig.18 As shown, the second slide slot 82 of the inner opening rocker arm 8 is used to flexibly connect one end of the super lock clutch rod 20. Initially, there is a gap between one end of the super lock clutch rod 20 and the left end of the second slide slot 82. When the inner opening wire 11 is pulled upward for the first time, the inner opening rocker arm 8 pushes the super lock clutch rod 20 to move upward, and the third boss 201 of the super lock clutch rod 20 pushes the third push portion 61 of the inner opening crank 6, so that the inner opening crank 6 moves clockwise, and the inner opening clutch rod 14 moves toward the left side under the action of the torsion spring 15 and the left end of the inner opening clutch rod 14 contacts the left side surface of the first slide slot 81, so that the inner opening clutch rod 14 is in a state capable of transmitting power to the pawl structure, that is, in a state of releasing the insurance. Therefore, through the drive between the inner opening rocker arm 8 and the inner opening clutch rod 14 and the inner opening crank 6, the linkage of the inner opening drive can be better, which is convenient for adjusting the release insurance state and the insurance state of the inner opening component.

[0093] Secondly, it should be noted that when the super lock motor worm 22 is started, the super lock worm wheel 13 is driven to rotate counterclockwise to the position shown in the figure and remain stationary, then the inner opening crank 6 will be forced to the upper safety position, at which time the inner and outer unlocking fails, and at the same time, because the protrusion at the left end of the super lock clutch rod 20 is also pushed to the left side of the first slide groove 81 of the inner opening rocker arm 8, the inner pull-release safety fails, and the door cannot be opened anyway. Therefore, by setting the super lock structure, the safety performance of the vehicle door lock after closing is further improved.

[0094] In some embodiments, the safety assembly includes a child lock structure 21, which is connected to the inner opening clutch rod 14 and is used to drive the inner opening clutch rod 14 to move between the upper safety position and the unsafe position.

[0095] In practice, the child lock structure 21 is movably connected to the inner opening clutch rod 14, and the child lock structure 21 is provided with a movable groove, so that the end of the inner opening clutch rod 14 can move in a small range. When the child lock structure 21 is rotated, the position of the inner opening clutch rod 14 can be changed, thereby switching the inner opening clutch rod 14 between the safety state and the safety state.

[0096] like Fig.19 As shown, the child lock structure 21 is mechanically rotated to open or unlock. For example, if the child lock structure 21 is rotated counterclockwise, the left end of the inner opening clutch rod 14 can move along the left side of the first slide groove 81 of the inner opening rocker 8 and toward the right side, so that the inner opening clutch rod 14 is switched to a state where power cannot be transmitted with the pawl structure, that is, it is in the insurance state; if the child lock structure 21 is rotated clockwise, the left end of the inner opening clutch rod 14 can move along the first slide groove 81 of the inner opening rocker 8 toward the left side, so that the inner opening clutch rod 14 can be switched to a state where power can be transmitted with the pawl structure, that is, it is in the insurance state. By setting the child lock structure 21, such as controlling the inner opening clutch rod 14 to move slightly toward the right side, so that the inner opening clutch rod 14 and the pawl structure cannot realize power transmission, and at the same time, it can not affect the position of the inner opening crank 6. At this time, the inner opening is in the insurance state, which can further ensure the safety of children in the car, prevent children from playing or accidentally opening the door lock, and improve safety.

[0097] In some embodiments, the safety assembly further includes an emergency safety structure 23 , which is movable relative to the inner crank 6 and is used to selectively restrict the inner crank 6 to a position corresponding to the upper safety state.

[0098] In practice, refer to Fig. 20As shown, the emergency safety structure 23 of the embodiment of the utility model is an emergency safety knob, and a fourth boss 231 is provided on the emergency safety knob 23. Among them, if the emergency safety knob 23 rotates clockwise, the fourth boss 231 on the emergency safety can drive the inner crank 6 to rotate counterclockwise, so that the inner crank 6 drives the inner clutch rod 14 to move, and the left end of the inner clutch rod 14 is restricted to the upper safety position, and the same function as the super lock can also be achieved. Therefore, by setting the emergency safety structure 23, in an emergency, the emergency safety knob can be mechanically rotated to achieve the function of upper safety.

[0099] In some embodiments, the door lock assembly 100 also includes an unlocking rocker arm 5, which is connected to the pawl structure. The inner opening component and the outer opening component are configured to act on the unlocking rocker arm 5 respectively when the safety is released, so as to push the unlocking rocker arm 5 to drive the pawl structure to move.

[0100] In practice, the unlocking rocker arm 5 is provided with a first push portion 51 and a second push portion 52. The first push portion 51 is adapted to selectively contact the inner opening clutch rod 14 to unlock the inner opening, and the second push portion 52 selectively contacts the outer opening clutch rod 12 to unlock the outer opening. Specifically, the unlocking rocker arm 5 contacts the pawl structure, such as Fig.14 As shown, when the inner opening clutch rod 14 contacts the first pushing portion 51 of the unlocking rocker arm 5, and the inner opening pull wire 11 is pulled upward, the inner opening clutch rod 14 can drive the unlocking rocker arm 5 to rotate through the first pushing portion 51, so that the unlocking rocker arm 5 drives the pawl structure to rotate so that the lock tongue 1 and the pawl structure are unlocked.

[0101] like Fig.15 As shown, when the outer opening clutch rod 12 contacts the second pushing portion 52 of the unlocking rocker arm 5, when the outer opening pull wire 17 is pulled to the right, the outer opening pull wire 17 can drive the outer opening pull rod 18 and the outer opening paddle 19 to rotate counterclockwise, so that the outer opening paddle 19 drives the outer opening lever 7 and the outer opening clutch rod 12 to rotate clockwise, so that the outer opening lever 7 drives the unlocking rocker arm 5 to rotate when in contact with the unlocking rocker arm 5, so that the unlocking rocker arm 5 drives the pawl structure to rotate, so that the pawl structure and the lock tongue 1 are disengaged and unlocked.

[0102] Therefore, by setting the unlocking rocker arm 5 and making the unlocking rocker arm 5 always keep in contact or connection with the pawl structure, the inner opening safety state is realized by separating the inner opening clutch rod 14 from the first pushing portion 51 of the unlocking rocker arm 5, that is, the left side of the inner opening clutch rod 14 is away from the left side of the first sliding groove 81 of the inner opening rocker arm 8; and the inner opening safety release state is realized by the inner opening clutch rod 14 contacting the first pushing portion 51 of the unlocking rocker arm 5, that is, the left side of the inner opening clutch rod 14 is close to and contacts the left side of the first sliding groove 81 of the inner opening rocker arm 8, thereby contacting the first pushing portion 51 of the inner opening rocker arm 8 to release the safety.

[0103] Similarly, the outer opening clutch rod 12 is dynamically connected to the outer opening lever 7, and the outer opening lever 7 is elastically connected to the door lock cover plate 103, that is, when the locking link 10 moves toward the left, the outer opening clutch rod 12 is pressed down, and then the outer opening clutch rod 12 moves downward to disengage the outer opening clutch rod 12 from the second pushing portion 52 of the unlocking rocker arm 5 to release the outer opening safety. When the locking link 10 moves toward the right, the outer opening clutch rod 12 moves upward under the action of the elastic force to contact the outer opening clutch rod 12 with the second pushing portion 52 of the unlocking rocker arm 5, and the safety is released at this time. The outside opening lever 7 is power-connected with the outside opening clutch lever 12. When the outside opening lever 7 is rotated, the outside opening clutch lever 12 can be driven to rotate and then the unlocking rocker arm 5 can be driven to rotate, so that the unlocking rocker arm 5 drives the pawl structure to rotate, so that the pawl structure is separated from the lock tongue 1 to unlock. In other words, no matter it is outside opening unlocking or inside opening unlocking, the door lock is ultimately unlocked by driving the unlocking rocker arm 5 to rotate, and the unlocking rocker arm 5 drives the pawl structure to rotate. By setting the unlocking rocker arm 5, it is convenient to respectively form power transmission between the inside opening component, the outside opening component and the pawl structure, thereby facilitating unlocking.

[0104] Of course, the embodiment of the utility model can also adopt electric unlocking. When the central control motor and the worm 24 of the central control part receive the electric unlocking signal, the central control worm gear structure 9 will be driven to rotate, and the second boss 92 on the central control worm gear structure 9 will toggle the unlocking rocker arm 5 to rotate counterclockwise, and the toggle of the unlocking rocker arm 5 will drive the pawl structure to rotate along the Figure 3 Turn the button in the unlocking direction to complete the electric unlocking action.

[0105] In some embodiments, the pawl structure includes a first pawl 2 and a second pawl 3, the first pawl 2 and the second pawl 3 are suitable for locking with the lock tongue 1 respectively, and the first pawl 2 is suitable for driving the second pawl 3 to unlock with the lock tongue 1 after moving in the direction of unlocking with the lock tongue 1.

[0106] In practice, when the door is closed, the lock ring 101 is locked from top to bottom, that is, Figure 4 and Figure 5 As shown, the lock tongue 1 rotates clockwise to the position shown in the figure, and is first blocked by the first ratchet 2, reaching a semi-locked state, and then the lock tongue 1 continues to rotate clockwise and is blocked by the second ratchet 3, reaching a locked state, that is, reaching Figure 3 When unlocked, refer to Figure 3 to Figure 4 , the first pawl 2 rotates counterclockwise, driving the second pawl 3 to rotate counterclockwise, at this time the lock tongue 1 pops out, then the cooperation of the first pawl 2 and the second pawl 3 can drive the lock tongue 1 to open, thereby unlocking.

[0107] Specifically, the second pawl 3 of the pawl structure has a contact arc surface, and there is a certain gradient between the contact arc surface of the second pawl 3 and the lock tongue 1, so that when the second pawl 3 is disengaged from the lock tongue 1, the lock tongue 1 and its contact surface will slowly rotate in the unlocking direction along the gradient, and the unlocking direction of the lock tongue 1 is Figure 3 The locking tongue 1 is rotated counterclockwise to gradually release the sealing reaction force exerted by the door lock ring 101, thereby achieving the effect of silencing and reducing noise when unlocking.

[0108] Therefore, by setting the pawl structure as the first pawl 2 and the second pawl 3, on the basis of ensuring that the first pawl 2 and the second pawl 3 can be linked, they can also better cooperate with the second notch 120 and the third notch 130 of the lock tongue 1, and the process of gradually closing or opening the car door can be realized, preventing the pawl structure or the lock tongue 1 of the door lock from being damaged due to excessive one-time force.

[0109] In some embodiments, the ice breaking assembly 4 is configured to push the locking tongue 1 and the second pawl 3 to lock after the locking tongue 1 and the first pawl 2 are locked.

[0110] At this time, the door lock is in a semi-locked state, that is, the first pawl 2 is in engagement with the third notch 130 of the lock tongue 1, and the second pawl 3 is not in engagement with the lock tongue 1, the door sends a semi-locked signal, the controller in the vehicle senses the semi-locked signal of the door, controls the motor for the ice-breaking wire 42 to be started, and drives the ice-breaking wire 42 to rotate along the pull line, that is, along the pull line. Figure 6 When the left side of the vehicle door is pulled, the suction ice-breaking pull wire 42 is pulled, and the suction rocker arm 44 is also pulled, driving the suction push arm 43 to rotate clockwise, so that the suction push arm 43 pushes the lock tongue 1 to overcome the sealing reaction force of the door lock ring 101, and makes the first pawl 2 cooperate with the second notch 120 of the lock tongue 1, and the second pawl 3 cooperates with the third notch 130 of the lock tongue 1, so as to achieve the fully locked position. That is to say, when the vehicle door is in the semi-locked position, the ice-breaking assembly 4 can be used to adjust the vehicle door to the fully locked position to achieve the safety of closing the vehicle door.

[0111] The door lock assembly of the embodiment of the utility model can improve the safety of door locking by cooperating the lock ring 101 of the vehicle door with the first notch 110 of the lock tongue 1, the first pawl 2 with the second notch 120 of the lock tongue 1, and the second pawl 3 with the third notch 130 of the lock tongue 1.

[0112] In some embodiments, the ice breaking assembly 4 is configured to drive the locking tongue 1 to unlock with the locking ring 101 after the first pawl 2 and the second pawl 3 are both unlocked with the locking tongue 1 .

[0113] In practice, refer to Figure 8 and Fig. 9As shown, due to the effect of the ice-sealing force under extreme working conditions, when the lock tongue 1 is frozen and cannot pop out normally, the vehicle detects that the lock tongue 1 fails to pop out normally and a signal is sent, at which time the ice-breaking action is performed. When the first pawl 2 is rotated, a snow-loading rod 45 is hinged on the first pawl 2, and the snow-loading rod 45 and the snow-loading rod 45 hinged at the upper end will push the suction push arm 43, so that one end of the suction push arm 43 falls into the rocker arm notch 411 of the ice-breaking rocker arm 41, and at this time, the motor of the suction and ice-breaking pull wire 42 is started again, and the suction rocker arm 44 is driven to rotate by pulling the suction and ice-breaking pull wire 42, so as to push the ice-breaking rocker arm 41 to rotate clockwise, and to move the lock tongue 1, so that the lock tongue 1 rotates counterclockwise, so that the second notch 120 of the lock tongue 1 is disengaged from the first pawl 2, and the third notch 130 is disengaged from one end of the second pawl 3. The ice-breaking component 4 can solve the problem that the car door cannot be unlocked in extreme weather.

[0114] At this time, after the first pawl 2 is disengaged from the second notch 120 of the lock tongue 1, and the second pawl 3 is disengaged from the third notch 130 of the lock tongue 1, the lock ring 101 of the vehicle door is separated from the first notch 110 of the lock tongue 1 during the counterclockwise rotation of the lock tongue 1, so that the vehicle door is opened.

[0115] The utility model embodiment also discloses a vehicle, which, by setting the above-mentioned door lock assembly 100, has the functions of electric unlocking, electric suction, electric ice breaking, mechanical insurance and release, electric insurance and release, inner pull release, double pull unlocking, super lock, child lock and emergency insurance. It is rich in functions and can adapt to various types of working conditions. At the same time, the door lock assembly 100 has a compact structure and can be suitable for automobile door locks that meet the functional requirements of most high-end automobile door locks.
