However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0044] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0045] like Figure 1-11 As shown, a vehicle door lock according to an embodiment of the utility model comprises a housing 1 , a lock body 2 and a detection switch 3 .

[0046] The housing 1 comprises a first housing 11 and a second housing 12 . The first housing 11 and the second housing 12 are connected and jointly surround a cavity. A plurality of first through holes are opened on the housing 1 .

[0047] The lock body 2 is disposed in the cavity, and the outer shell 1 wraps the main body of the lock body 2 to enhance the dustproof effect.

[0048] The lock body 2 includes a lock housing 21 and a locking assembly 22 movably arranged in the lock housing 21 , an outer opening release link 23 , an inner opening assembly 24 , an emergency lock assembly 25 , an inner locking link 26 , a child safety lock assembly 27 and an electric mechanism 28 .

[0049] The lock housing 21 is provided with multiple second through holes corresponding to the multiple first through holes respectively, the child safety lock assembly 27 is connected to the inner opening assembly 24, and the outer opening release rod 23, the inner opening assembly 24, the emergency lock assembly 25, the inner locking rod 26 and the child safety lock assembly 27 correspond to the second through holes respectively.

[0050] The outer opening release link 23 , the emergency lock assembly 25 , the inner locking link 26 , and the electric mechanism 28 are all connected to the locking assembly 22 , the inner opening assembly 24 is connected to the outer opening release link 23 , and the child protection lock assembly 27 is connected to the inner opening assembly 24 .

[0051] The emergency lock assembly 25 controls the connection and disconnection of the outer opening release link 23 and the locking assembly 22 , and the child protection lock assembly 27 controls the connection and disconnection of the inner opening assembly 24 and the locking assembly 22 .

[0052] After the locking assembly 22 is locked, the outward release link 23 is pulled to unlock it.

[0053] After the locking assembly 22 is locked, the inner opening assembly 24 is pulled, so that the inner opening assembly 24 drives the outer opening release link 23 to move, thereby unlocking the locking assembly 22.

[0054] The external outward opening connecting rod extends into the lock housing 21 through the first through hole and the second through hole and is connected to the outward opening release connecting rod 23 .

[0055] The external inner opening connecting rod extends into the lock housing 21 through the first through hole and the second through hole and is connected to the inner opening component 24 .

[0056] The external inner locking link extends into the lock housing 21 through the first through hole and the second through hole and is connected to the inner locking link 26 .

[0057] An external screwdriver or wrench is used to adjust the emergency lock assembly 25 and the child-proof lock assembly 27 through the first through hole.

[0058] For example, when the passenger is a child, in order to prevent the child from pulling the inner opening handle to open the door, the child-proof lock assembly 27 is adjusted by a screwdriver or a wrench to disconnect the inner opening assembly 24 from the locking assembly 22.

[0059] For example, when the passenger is an adult, the child-proof lock assembly 27 is adjusted by a screwdriver or a wrench to connect the inner opening assembly 24 to the locking assembly 22, so that the door can be opened by pulling the inner opening handle.

[0060] When the emergency lock assembly 25 is in the first state, the outward release link 23 is connected to the locking assembly 22, and the outward release link 23 can control the locking assembly 22 to unlock; when the emergency lock assembly 25 is in the second state, the outward release link 23 is disconnected from the locking assembly 22, and the outward release link 23 cannot control the locking assembly 22 to unlock.

[0061] The detection switch 3 is disposed in the lock housing 21 , and the detection switch 3 is configured to detect the locking and unlocking states of the locking assembly 22 .

[0062] The function setting of the detection switch 3 is equivalent to the existing door touch switch. The difference is that the door touch switch is installed on the vehicle body and detects whether the vehicle door is closed in place; while the detection switch 3 of the utility model is installed in the lock housing 21, and the detection switch 3 detects whether the locking assembly 22 is locked in place.

[0063] The detection switch 3 detects the state of the locking assembly 22 by contacting the locking assembly 22. When the detection switch 3 detects that the locking assembly 22 is in the locked state, the circuit of the detection switch 3 is closed to send the locked in place information to the vehicle electronic control board. When the detection switch 3 detects that the locking assembly 22 is in the unlocked state, the circuit of the detection switch 3 is disconnected to send the unlocked or unlocked information to the vehicle electronic control board.

[0064] Of course, the detection method is not limited to contact detection, and the state of the locking assembly 22 can also be detected by an inductive non-contact method. Those skilled in the art can select the detection method of the detection switch 3 according to actual needs.

[0065] like Figure 3-6 As shown, in a preferred embodiment of the present invention, the locking assembly 22 includes a ratchet 221 , a pawl 222 and a pawl push rod 223 movably mounted in the lock housing 21 .

[0066] The ratchet 221 and the pawl 222 can switch between a locking position and an initial position. The ratchet 221 is provided with a groove 2211. When the lock buckle on the door frame of the vehicle body is inserted into the groove 2211, the lock buckle pushes the ratchet 221 to rotate.

[0067] After the ratchet wheel 221 rotates from the initial position to the locking position, the pawl 222 limits the locking position of the ratchet wheel 221 .

[0068] One end of the ratchet push rod 223 is movably connected to the ratchet 222 , and the other end of the ratchet push rod 223 is movably connected to the outward-opening release link 23 .

[0069] When the external opening handle pulls the opening release link 23, the opening release link 23 drives the pawl push rod 223 to move, and the pawl push rod 223 drives the pawl 222 to rotate, and the pawl 222 releases the limit on the ratchet 221, so that the ratchet 221 returns to its initial position under the elastic force of the spring, thereby achieving unlocking.

[0070] One end of the emergency lock assembly 25 is movably connected to the pawl push rod 223 , the electric mechanism 28 is connected to the emergency lock assembly 25 , and the inner locking link 26 is connected to the electric mechanism 28 .

[0071] When the vehicle is powered on and the electric mechanism 28 does not work, the emergency lock assembly 25 needs to be manually rotated. When the emergency lock assembly 25 is locked, the emergency lock assembly 25 pushes the pawl push rod 223 to separate from the pawl 222, making the external opening handle ineffective.

[0072] like Figure 4 As shown, in a preferred embodiment of the utility model, the outward opening release link 23 is provided with a first hinged portion 231 near one end, and the first hinged portion 231 can be movably installed in the lock housing 21, and the other end of the outward opening release link 23 is provided with a first connecting portion 232 for connecting with the outward opening pull rod, and the first connecting portion 232 corresponds to the second through hole, and a second hinged portion 233 is provided in the middle part of the outward opening release link 23, and the second hinged portion 233 is movably connected to the pawl push rod 223.
