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.

[0040] There are two main ice-breaking schemes for existing automobile electrolytic door locks. One is to use the ice-breaking wire of the double-wire actuator to drive the mechanical structure inside the door lock to open the door, but this scheme is complex and cumbersome in structure and high in cost; the second is to break the ice by adding an auxiliary mechanism, but most of these schemes have complex structural designs, poor linkage, and increase the size of the door lock, which is not conducive to the arrangement of the door lock and has high requirements on the accuracy of the vehicle body, which not only increases the cost but also makes it easy for the ice-breaking to fail.

[0041] Reference below Figure 1-Figure 3 A door lock assembly according to an embodiment of the present utility model is described.

[0042] The door lock assembly 1 according to the utility model comprises a lock housing 11, a lock tongue 12, and an ice-breaking module. The lock tongue 12 is rotatably arranged on the lock housing 11; the ice-breaking module is movably arranged on the lock housing 11 to drive the lock tongue 12 to rotate toward the unlocking direction.

[0043] According to the door lock assembly 1 of the present invention, a lock housing 11 is provided, which is the basic structure of the door lock assembly 1 and can be used to support and cover other functional components of the door lock assembly 1. A lock tongue 12 is rotatably provided on the lock housing 11, and the lock tongue 12 is a structure for realizing the unlocking or locking function of the door lock assembly 1. An ice breaking module 13 is also provided on the lock housing, and the ice breaking module 13 is movably provided on the lock housing 11 so as to drive the lock tongue 12 to rotate and unlock in certain circumstances. Specifically, when the door lock assembly 1 is in extreme weather and the door lock is frozen and cannot be unlocked normally, the ice-breaking module 13 can provide driving force through its own mechanical transmission, and directly apply the driving force to the lock tongue 12 to drive the lock tongue 12 to rotate and thereby achieve ice breaking. Compared with the prior art, the door lock assembly 1 of the utility model directly uses the ice-breaking module 13 to provide driving force for breaking ice, without the need to set up additional auxiliary mechanisms or redundant driving structures. The overall structure is simple and easy to assemble. The linkage between the ice-breaking module and the lock tongue 12 is high, the ice-breaking effect is good, and the structure is simple, which can effectively reduce the cost of the door lock assembly 1.

[0044] According to an embodiment of the utility model, the ice-breaking module 13 includes an ice-breaking rocker arm 132, which is rotatably arranged on the lock housing 11. When the door lock assembly 1 needs to be unlocked by breaking ice, the ice-breaking rocker arm 132 rotates to cooperate with the lock tongue 12 and transmits torque to the lock tongue 12. The lock tongue 12 is driven by the ice-breaking rocker arm 132 to rotate to achieve ice breaking, thereby completing the unlocking of the door lock assembly 1.

[0045] According to one embodiment of the utility model, the ice-breaking module 13 also includes a suction rocker arm 131, which is connected to the power source and is rotatably arranged on the lock housing 11, and the suction rocker arm 131 can selectively cooperate with the ice-breaking rocker arm 132 or with the lock tongue 12; wherein, when the suction rocker arm 131 cooperates with the lock tongue 12, the suction rocker arm 131 is suitable for driving the lock tongue 12 to rotate in the locking direction; when the suction rocker arm 131 cooperates with the ice-breaking rocker arm 132, the suction rocker arm 131 is suitable for driving the ice-breaking rocker arm 132 to drive the lock tongue 12 to rotate in the unlocking direction.

[0046] Since the door lock assembly 1 needs to be locked and unlocked by breaking ice through the ice breaking module 13, the structure of the ice breaking module 13 will affect the use of the door lock assembly 1. The ice breaking module 13 is provided with a suction rocker arm 131, which is connected to the power source and rotatably arranged on the lock housing 11, and the suction rocker arm 131 can drive the lock tongue 12 to rotate toward the locking direction.

[0047] Specifically, the suction rocker arm 131 can cooperate with the ice-breaking rocker arm 132 or directly cooperate with the lock tongue 12. The suction rocker arm 131 can be understood as having two different states, a first state and a second state, which respectively correspond to the locking and ice-breaking unlocking of the door lock assembly 1. It should be noted that the first state and the second state are only used to describe the position and action of the suction rocker arm 131.

[0048] When the door lock assembly 1 needs to be locked, the suction rocker arm 131 is in the first state. At this time, the suction rocker arm 131 rotates a certain angle and then directly cooperates with the lock tongue 12 and drives the lock tongue 12 to rotate in the locking direction to realize the locking function of the door lock assembly 1; when the door lock assembly 1 needs to break ice and unlock, the suction rocker arm 131 is in the second state. At this time, the suction rocker arm 131 rotates a certain angle and then cooperates with the ice-breaking rocker arm 132 and drives the ice-breaking rocker arm 132 to rotate. After the ice-breaking rocker arm 132 rotates, it can cooperate with the lock tongue 12 and transmit the torque to the lock tongue 12. After the lock tongue 12 is driven by the ice-breaking rocker arm 132, it can rotate to achieve ice breaking, thereby completing the unlocking of the door lock assembly 1. The ice-breaking module 13 realizes the locking and ice-breaking unlocking functions of the door lock assembly 1 by setting a suction rocker arm 131 and cooperating with the ice-breaking rocker arm 132. When locking, the suction rocker arm 131 directly acts on the lock tongue 12 and drives the lock tongue 12 to rotate in the locking direction; when unlocking by breaking ice, the suction rocker arm 131 drives the ice-breaking rocker arm 132 to break ice and unlock. The suction rocker arm 131 can achieve different capabilities in different working conditions without adding other auxiliary structures, making the overall structure of the ice-breaking module 13 simpler.

[0049] According to an embodiment of the present invention, the door lock assembly 1 further includes a first lever 152 , which is movably disposed on the lock housing 11 , and is suitable for driving the suction rocker arm 131 to move to a state of cooperating with the ice-breaking rocker arm 132 .

[0050] During assembly, the door lock assembly 1 may also be provided with a first lever 152, which may be used as a driving member of the suction rocker arm 131, so as to drive the suction rocker arm 131 to cooperate with the ice-breaking rocker arm 132 under certain circumstances. Specifically, when the door lock assembly 1 needs to be locked, the suction rocker arm 131 drives the lock tongue 12 to rotate in the direction of locking, and the lock tongue 12 is locked after rotating a certain angle; when the door lock assembly 1 needs to be unlocked by breaking ice, the first lever 152 may drive the suction rocker arm 131 to cooperate with the ice-breaking rocker arm 132, and the ice-breaking rocker arm 132 drives the lock tongue 12 to rotate in the direction of unlocking, and the unlocking function is completed after the lock tongue 12 rotates a certain angle. The door lock assembly 1 may control the linkage relationship between the ice-breaking rocker arm 132 and the suction rocker arm 131 through the first lever 152, thereby realizing the normal locking and unlocking functions of the door lock assembly 1, reducing unnecessary auxiliary parts and driving members, simplifying the structure of the door lock assembly 1, and facilitating the arrangement of the door lock assembly 1.

[0051] According to one embodiment of the utility model, the suction rocker arm 131 includes a first arm 1311 and a second arm 1312. The first arm 1311 is rotatably disposed on the lock housing 11 and is suitable for being connected to a power source; the second arm 1312 is rotatably disposed on the first arm 1311, and a first protrusion 13121 cooperating with one side of the first lever 152 and a second protrusion 13122 cooperating with the ice-breaking rocker arm 132 are formed on the second arm 1312.

[0052] Since the suction rocker arm 131 can directly cooperate with the lock tongue 12 or with the ice-breaking rocker arm 132, the structure of the suction rocker arm 131 will affect the locking and ice-breaking unlocking functions of the door lock assembly 1. The suction rocker arm 131 is provided with a first arm 1311 and a second arm 1312, wherein the first arm 1311 is rotatably connected to the lock housing 11; and the second arm 1312 is rotatably connected to the first arm 1311. The first state and the second state of the suction rocker arm 131 can be understood as two states of the second arm 1312, that is, the second arm 1312 can switch between the first state and the second state. Specifically, the second arm 1312 is formed with a first convex portion 13121 that cooperates with one side of the first lever 152 and a second convex portion 13122 that cooperates with the ice-breaking rocker arm 132. When the door lock assembly 1 is locked, the second arm 1312 is in a first state, and the power source can provide a driving force to drive the first arm 1311 and simultaneously drive the second arm 1312 to rotate. After the second arm 1312 rotates a certain angle, a portion of the second arm 1312 that protrudes close to the lock tongue 12 can cooperate with the lock tongue 12 to stop, and transmit the torque to the lock tongue 12 to make the lock tongue 12 rotate in the locking direction to achieve the locking of the door lock assembly 1; when the door lock assembly 1 is unlocked, the first lever 152 rotates and cooperates with the first convex portion 13121 The second arm 1312 is driven by the stopper to push the second arm 1312 to rotate relative to the first arm 1311. After the second arm 1312 rotates a certain angle, it is converted from the first state to the second state. At this time, the power source can provide a driving force to drive the first arm 1311 and the second arm 1312 to rotate together. When the first arm 1311 and the second arm 1312 rotate a certain angle under the drive of the power source, the second protrusion 13122 on the second arm 1312 can cooperate with the ice-breaking rocker arm 132 and transmit the torque to the ice-breaking rocker arm 132. The ice-breaking rocker arm 132 rotates under the drive of the second arm 1312. After the ice-breaking rocker arm 132 rotates a certain angle, it can cooperate with the lock tongue 12 and drive the lock tongue 12 to rotate in the unlocking direction to achieve ice-breaking unlocking. The structure of the first arm 1311 and the second arm 1312 enables the suction rocker arm 131 to perform different movements in different states, realizing the functions of locking and ice-breaking unlocking of the door lock assembly 1.

[0053] According to an embodiment of the present invention, the door lock assembly 1 further includes a first reset member 161, which is disposed between the first arm 1311 and the second arm 1312 to drive the second arm 1312 to reset. The door lock assembly 1 further includes a first reset member 161, which can be disposed between the first arm 1311 and the second arm 1312, or on a side of the second arm 1312 away from the first arm 1311, and the specific position can be determined according to the actual assembly situation. The first reset member 161 can reset the second arm 1312. When the door lock assembly 1 completes the ice-breaking unlocking, the second arm 1312 is in the second state. At this time, the first reset member 161 can reset the second arm 1312 to the first state to realize the reset process of the second arm 1312, so that when the door lock assembly 1 needs to be locked, the power source can drive the first arm 1311 to drive the second arm 1312 to directly act on the lock tongue 12 to make the lock tongue 12 rotate in the locking direction to complete the locking. The structure of the first reset member 161 enables the door lock assembly 1 to be locked normally after completing the ice-breaking unlocking, thereby realizing the normal use of the door lock assembly 1.

[0054] In some embodiments, the door lock assembly 1 further includes an actuator 171, which can be understood as a power source connected to the first arm 1311, and the actuator 171 can drive the suction rocker arm 131 to rotate. When the door lock assembly 1 is locked or unlocked by breaking ice, the actuator 171 can provide a driving force to the first arm 1311 through the power source to drive the first arm 1311 to drive the second arm 1312 to rotate, thereby achieving the locking or ice-breaking unlocking of the door lock assembly 1.

[0055] In some embodiments, the actuator 171 may be a pull-wire.

[0056] According to an embodiment of the utility model, a groove 13221 suitable for accommodating the second convex portion 13122 is formed on the ice-breaking rocker arm 132. The door lock assembly 1 is provided with the groove 13221 on the ice-breaking rocker arm 132. When the door lock assembly 1 needs to be unlocked by breaking ice, the second arm 1312 can be converted from the first state to the second state, and the actuator 171 drives the first arm 1311 and the second arm 1312 to rotate. After the second arm 1312 rotates a certain angle, the second convex portion 13122 on the second arm 1312 can be accommodated in the groove 13221 and matched with the groove 13221. At this time, the second arm 1312 can transmit the torque to the ice-breaking rocker arm 132 through the cooperation of the second convex portion 13122 and the groove 13221 so as to drive the ice-breaking rocker arm 132 to rotate, thereby achieving ice-breaking unlocking. The structure of the groove 13221 improves the stability of the cooperation between the second arm 1312 and the ice-breaking rocker arm 132 when the door lock assembly 1 is unlocked by breaking ice.

[0057] According to one embodiment of the utility model, a first pivot portion 1321 is provided on the lock housing 11, and the ice-breaking rocker arm 132 includes a first rod portion 1322 and a second rod portion 1323, the first rod portion 1322 is rotatably provided on the first pivot portion 1321 and the first rod portion 1322 is formed with a groove 13221 open toward away from the first pivot portion 1321; the second rod portion 1323 is connected to the first pivot portion 1321 and the free end of the second rod portion 1323 is formed with a third protrusion 13231 suitable for cooperating with the other side of the lock tongue 12.

[0058] Since the ice-breaking rocker arm 132 is a key structure for realizing ice-breaking unlocking in the door lock assembly 1, the structure of the ice-breaking rocker arm 132 will affect the ice-breaking unlocking function of the door lock assembly 1. A first pivoting portion 1321 is provided on the lock housing 11, and the ice-breaking rocker arm 132 is constructed with a first rod portion 1322 and a second rod portion 1323, wherein the first rod portion 1322 is rotatably provided on the first pivoting portion 1321, and the second rod portion is connected to the first rod portion, which can also be understood as the first rod portion 1322 and the second rod portion 1323 are rotatably connected to the first pivoting portion 1321, respectively.

[0059] Specifically, the first rod portion 1322 is formed with a groove 13221 that is open toward and away from the first pivot portion 1321, and the free end of the second rod portion 1323 is formed with a third convex portion 13231. When the door lock assembly 1 needs to break ice and unlock, the second arm 1312 is converted to the second state, and the actuator 171 drives the first arm 1311 to drive the second arm 1312 to rotate. When the second arm 1312 rotates a certain angle, the second convex portion 13122 on the second arm 1312 enters In the groove 13221 on the first rod 1322, the second arm 1312 transmits torque to the first rod 1322 through the cooperation of the second protrusion 13122 and the groove 13221. The first rod 1322 drives the entire ice-breaking rocker arm 132 to rotate around the pivot axis of the first pivot 1321. When the second rod 1323 rotates a certain angle, the third protrusion 13231 can cooperate with the other side of the lock tongue 12 and drive the lock tongue 12 to rotate to achieve ice-breaking unlocking. The structure of the first rod 1322, the second rod 1323 and the first pivot 1321 can transmit the force transmitted from the second arm 1312 to the first rod 1322 and act on the lock tongue 12 through the third protrusion 13231, thereby achieving ice-breaking unlocking of the door lock assembly 1, so that the door lock can be normally unlocked even in extreme weather.

[0060] According to an embodiment of the present invention, a first matching portion 121 is formed on the radial outer periphery of the locking tongue 12 , and the third protrusion 13231 is suitable for abutting against the first matching portion 121 in the circumferential direction to drive the locking tongue 12 to rotate in the circumferential direction.

[0061] Since the lock tongue 12 can directly cooperate with the second rocker arm or with the ice-breaking rocker arm 132, the structure of the lock tongue 12 will affect the locking and ice-breaking unlocking of the door lock assembly 1. The radial periphery of the lock tongue 12 is formed with a first matching portion 121, and the first matching portion 121 extends in a direction away from the lock tongue 12. The first matching portion 121 can cooperate with the third protrusion 13231 to stop. Specifically, when the door lock assembly 1 is unlocked by breaking ice, the second arm 1312 is converted to the second state, that is, the second arm 1312 rotates a certain angle and cooperates with the ice-breaking rocker arm 132 and drives the ice-breaking rocker arm 132 to rotate. After the ice-breaking rocker arm 132 rotates a certain angle, the third protrusion 13231 can cooperate with the ice-breaking rocker arm 132. The other side of the first matching part 121 in the circumferential direction is abutted, at this time, the ice-breaking rocker arm 132 can drive the lock tongue 12 to rotate in the unlocking direction to achieve ice-breaking unlocking; when the door lock assembly 1 is locked, the second arm 1312 is in the first state, and after the second arm 1312 rotates a certain angle, the part of the second arm 1312 protruding toward the lock tongue 12 can also abut against the first matching part 121 in the circumferential direction, at this time, the second arm 1312 can directly push the lock tongue 12 to rotate in the locking direction to achieve locking. The structure of the first matching part 121 enables the lock tongue 12 to cooperate with the second arm 1312 or the ice-breaking rocker arm 132 respectively under different working conditions, so as to facilitate the normal use of the locking and ice-breaking unlocking functions of the door lock assembly 1.

[0062] In some embodiments of the utility model, the door lock assembly 1 may further be provided with a second reset member 162, which may be provided between the first pivoting portion 1321 and the lock housing 11, and the second reset member 162 may reset the ice-breaking rocker arm 132. When the door lock assembly 1 completes the ice-breaking unlocking, the ice-breaking rocker arm 132 abuts against the first matching portion 121. At this time, the second arm 1312 is reset to the first state under the action of the first reset member 161, and the ice-breaking rocker arm 132 may be reset to the initial position under the action of the second reset member 162, so that when the door lock assembly 1 needs to be locked, the position of the ice-breaking rocker arm 132 will not interfere with the rotation of the lock tongue 12. The structure of the second reset member 162 enables the door lock assembly 1 to be locked normally after completing the ice-breaking unlocking, thereby realizing the normal use of the door lock assembly 1.

[0063] According to one embodiment of the utility model, the door lock assembly 1 also includes a second lever 151 and a locking module 14. The second lever 151 is rotatably disposed on the lock housing 11 and is suitable for driving the first lever 152. The locking module 14 is disposed on the lock housing 11 and can selectively cooperate with the lock tongue 12 to limit the rotation of the lock tongue 12. The locking module 14 is linked with the second lever 151, and the second lever 151 is suitable for driving the locking module 14 to separate from the lock tongue 12.

[0064] Specifically, the second lever 151 is linked with the first lever 152 and is rotatably disposed on the lock housing 11. The second lever 151 can drive the first lever 152 to move so as to drive the suction rocker arm 131 to move to cooperate with the ice-breaking rocker arm 132. The lock housing 11 is also provided with a locking module 14, which can cooperate with the lock tongue 12 to selectively limit the rotation of the lock tongue 12, thereby preventing the door lock assembly 1 from being mis-locked, and improving the safety of the door lock assembly 1. When the door lock assembly 1 needs to be locked, the suction rocker arm 131 is in the first state and can drive the lock tongue 12 to rotate in the locking direction. The locking process is completed after the lock tongue 12 rotates a certain angle. At this time, the locking module 14 can cooperate with the lock tongue 12 to limit the rotation of the lock tongue 12 to avoid the door lock assembly 1 from being mislocked; when the door lock assembly 1 needs to be unlocked, the suction rocker arm 131 is transformed from the first state to the second state. At the same time, the second lever 151 drives the locking module 14 to rotate a certain angle to release the restriction on the lock tongue 12. The lock tongue 12 can complete the unlocking process after rotating a certain angle under the drive of the suction rocker arm 131.

[0065] According to one embodiment of the utility model, the locking module 14 includes a locking block 141 and a limiting assembly 142. The locking block 141 is coaxially arranged with the second lever 151 and is suitable for rotating under the drive of the second lever 151. The locking block 141 can selectively stop with the lock tongue 12 to limit the rotation of the lock tongue 12; the limiting assembly 142 is linked with the second lever 151, and the limiting assembly 142 is suitable for limiting the rotation of the locking block 141.

[0066] Since the locking module 14 can be used to limit the movement of the lock tongue 12, the structure of the locking module 14 will affect the self-locking of the door lock assembly 1. The locking module 14 is provided with a locking block 141 and a limiting assembly 142. The locking block 141 can limit the movement of the lock tongue 12 so that the door lock assembly 1 can achieve self-locking. The self-locking in the present utility model can be understood as the lock tongue 12 is limited by the locking block 141 and cannot rotate. The door lock assembly 1 cannot be unlocked at this time. For example, when the locking block 141 and the lock tongue 12 are stopped, the lock tongue 12 cannot rotate. At this time, no matter whether the ice breaking module 13 is in the first state or the second state, it cannot drive the lock tongue 12 to rotate, that is, the door lock assembly 1 cannot be unlocked, and the door lock assembly 1 is in a self-locking state. Specifically, the lock block 141 is coaxially arranged with the second lever 151 and can rotate under the drive of the second lever 151. The coaxial arrangement of the lock block 141 and the second lever 151 can reduce the occupied space of the locking device and facilitate the arrangement of the locking device; the limiting assembly 142 is linked with the second lever 151, and the rotation of the second lever 151 can drive the limiting assembly 142 to rotate to limit the movement of the lock block 141. When the door lock assembly 1 is in the self-locking state, the limiting assembly 142 abuts against the lock block 141, and the lock block 141 cannot rotate. At this time, the lock block 141 abuts against the lock tongue 12, and the lock tongue 12 cannot rotate, which can avoid the door lock assembly 1 from being locked by mistake and improve the safety of the door lock assembly 1. When the door lock assembly 1 needs to be unlocked, the second lever 151 rotates to drive the limiting component 142 to disengage from the lock block 141. At this time, the movement of the lock block 141 is not limited by the limiting component 142, and the lock block 141 can rotate driven by the second lever 151. When the lock block 141 rotates a certain angle, the movement of the lock tongue 12 is not limited by the lock block 141, and the door lock assembly 1 can be unlocked normally.

[0067] According to one embodiment of the utility model, the limiting assembly 142 includes a pawl 1421 and a limiting arm 1422. The pawl 1421 is rotatably disposed on the lock housing 11 and is linked to the second lever 151; the limiting arm 1422 is rotatably disposed on the lock housing 11 and is linked to the pawl 1421. The limiting arm 1422 abuts against one circumferential side of the lock block 141 to limit the lock block 141 from disengaging from the lock tongue 12. The limiting arm 1422 is suitable for rotating under the drive of the pawl 1421 to release the restriction on the lock block 141.

[0068] Since the limit assembly 142 is a structure that limits the movement of the lock block 141, the structure of the limit assembly 142 will affect the self-locking function of the door lock assembly 1. The limit assembly 142 is provided with a pawl 1421 and a limit arm 1422. The limit arm 1422 can limit the movement of the lock block 141, and the pawl 1421 is a structure that drives the limit arm 1422 to move. Specifically, the pawl 1421 is rotatably provided on the lock housing 11 and linked to the second lever 151, and the limit arm 1422 is rotatably provided on the lock housing 11 and linked to the pawl 1421. When the door lock assembly 1 is in the self-locking state, the limit arm 1422 abuts against one side of the circumferential direction of the lock block 141. At this time, the lock block 141 abuts against the lock tongue 12 and cannot rotate. When the door lock assembly 1 needs to release the self-locking state, the second lever 151 is released. 51 drives the pawl 1421 to rotate, and the rotation of the pawl 1421 can drive the limiting arm 1422 to rotate. After the limiting arm 1422 rotates a certain angle, it disengages from one side of the circumferential direction of the lock block 141. At this time, the movement of the lock block 141 is not restricted by the limiting arm 1422. The lock block 141 can move along the outer periphery of the limiting arm 1422 driven by the second shift rod 151. It can also be understood that at this time the limiting arm 1422 rotates to one side of the radial direction of the lock block 141. At this time, the limiting arm 1422 releases the restriction on the lock block 141. When the lock block 141 rotates a certain angle, the restriction of the lock tongue 12 is released, and the door lock assembly 1 can be unlocked normally.

[0069] According to one embodiment of the utility model, the limiting arm 1422 includes a second pivot portion 14221, a first limiting rod 14222 and a second limiting rod 14223, the second pivot portion 14221 is rotatably connected to the lock housing 11; the first limiting rod 14222 is connected to the second pivot portion 14221 and the free end is matched with the pawl 1421; the second limiting rod 14223 is connected to the second pivot portion 14221 and extends toward the lock tongue 12, and the free end of the second limiting rod 14223 is suitable for matching with the lock block 141.

[0070] Since the limiting arm 1422 is a structure that limits the rotation of the lock block 141, the structure of the limiting arm 1422 will affect the self-locking function of the door lock assembly 1. The limiting arm 1422 is constructed with a second pivoting portion 14221, a first limiting rod 14222, and a second limiting rod 14223, wherein the second pivoting portion 14221 is rotatably connected to the lock housing 11, and the limiting arm 1422 rotates around the second pivoting portion 14221; the first limiting rod 14222 and the second limiting rod 14223 are respectively connected to the second pivoting portion 14221 and are spaced apart on the outer periphery of the second pivoting portion 14221. Specifically, the free end of the first limiting rod 14222 cooperates with the pawl 1421, and the free end of the second limiting rod 14223 cooperates with the lock block 141. When the door lock assembly 1 needs to release the self-locking, the second lever 151 drives the pawl 1421 to drive the first limiting rod 14222 to rotate, and the first limiting rod 14222 drives the entire limiting arm 1422 to rotate around the pivot axis of the second pivot part 14221. When the second limiting rod 14223 rotates to one side radially with the lock block 141, the restriction on the lock block 141 can be released. At this time, the lock block 141 can rotate. After the lock block 141 rotates a certain angle, the rotation of the lock tongue 12 is not restricted by the lock block 141, and the door lock assembly 1 completes the process of releasing the self-locking. The second pivoting portion 14221 , the first limiting rod 14222 , and the second limiting rod 14223 are configured so that the door lock assembly 1 can achieve self-locking and self-unlocking, thereby realizing normal use of the door lock assembly 1 .

[0071] According to an embodiment of the present invention, the door lock assembly 1 further includes a first position switch 172, which is disposed on the lock housing 11 and is suitable for detecting the position of the lock block 141. During assembly, the door lock assembly 1 can also be equipped with the first position switch 172 on the lock housing 11. When the door lock assembly 1 is in use, the lock tongue 12 is limited by the lock block 141 and cannot rotate, which can also be understood as the lock tongue 12 is in a fully locked state. When the door lock assembly 1 needs to release the fully locked state of the lock tongue 12, the second lever 151 drives the pawl 1421 to rotate, and the pawl 1421 drives the limiting arm 1422 to rotate. When the limiting arm 1422 rotates to one side of the radial direction of the lock block 141, it no longer restricts the movement of the lock block 141. At this time, the lock block 141 can rotate under the drive of the second lever 151. After the lock block 141 rotates a certain angle, the lock tongue 12 is free from the obstruction of the lock block 141 and can rotate. At this time, the lock block 141 contacts the first position switch 172 and activates the first position switch 172. The first position switch 172 feedbacks that the lock tongue 12 is out of the fully locked state. The setting of the first position switch 172 can monitor the real-time state in the door lock assembly 1 in real time, so as to confirm whether the process of releasing the full lock of the lock tongue 12 can be completed normally, which is convenient for the subsequent locking and ice-breaking unlocking of the door lock.

[0072] According to an embodiment of the present utility model, the door lock assembly 1 further includes a second position switch 173, which is disposed on the lock housing 11 and is suitable for detecting the position of the second lever 151. During assembly, the door lock assembly 1 can also be equipped with the second position switch 173 on the lock housing 11. During use of the door lock assembly 1, after the lock tongue 12 is released from the fully locked state, it may still be limited by the second lever 151. When the lock tongue 12 is limited by the second lever 151 and cannot move, it can be understood that the lock tongue 12 is in a semi-locked state. When the door lock assembly 1 needs to release the semi-locked state of the lock tongue 12, the second lever 151 drives the pawl 1421 to continue to rotate. When the second lever 151 rotates a certain angle again, the rotation of the lock tongue 12 is no longer limited by the second lever 151. At this time, the second lever 151 contacts the second position switch 173 and activates the second position switch 173. The second position switch 173 feedbacks that the lock tongue 12 is out of the semi-locked state. The second position switch 173 can monitor the real-time status of the door lock assembly 1 in real time, so as to confirm whether the half-locking process of the lock tongue 12 can be completed normally, and facilitate the subsequent locking and ice-breaking unlocking of the door lock.

[0073] In some embodiments of the utility model, the ice-breaking module 13 and the locking module 14 are located on both sides of the lock tongue 12. During assembly, the ice-breaking module 13 and the locking module 14 are respectively arranged on both sides of the lock tongue 12, and the movements of the two modules do not interfere with each other, ensuring that the door lock assembly 1 can be locked, ice-breaking unlocked, and the lock tongue 12 can be released from the full lock state and the half lock state. The locking module 14 and the ice-breaking module 13 are arranged on both sides of the lock tongue 12 to improve the compactness of the layout of the door lock assembly 1, reduce the occupied space of the door lock assembly 1, and facilitate the assembly of the door lock assembly 1.

[0074] It is worth noting that the certain angles mentioned in any of the above embodiments are the angles at which the corresponding structures rotate in different states. The angles required for rotation of different structures may be the same or different, and are specifically limited according to the actual conditions such as the size and layout of each structure in the door lock assembly 1.
