[0036] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0037] Reference below Figure 1-Figure 10 A vehicle door lock 100 according to an embodiment of the present invention is described. The vehicle door lock 100 may adopt a control method of the vehicle door lock 100 , and the vehicle door lock 100 may be applied to a vehicle.

[0038] Combination Figure 1-Figure 4As shown, the door lock 100 of the vehicle according to the present invention can mainly include: a door lock body 10, a card plate assembly 20, a stop plate assembly 30 and a controller 40, wherein a lock buckle 11 is arranged on the door lock body 10, and the lock buckle 11 has a locking position and an unlocking position, and the lock buckle 11 is movable between the locking position and the unlocking position, so that when the lock buckle 11 is in the locking position, the lock buckle 11 and the lock ring of the vehicle body are locked with each other, and the vehicle door is connected and locked with the vehicle body; when the lock buckle 11 is in the unlocking position, the lock buckle 11 and the lock ring of the vehicle body are unlocked, and the vehicle door is disconnected from the vehicle body, so that the lock buckle 11 only needs to be moved between the locking position and the unlocking position, and the vehicle door can be selectively locked and unlocked with the vehicle body through the lock buckle 11, so that the normal opening and closing of the vehicle door can be realized.

[0039] Combination Figure 1-Figure 4 As shown, the card plate assembly 20 can mainly include a card plate 21 and a card plate switch 22, the card plate 21 can be rotatably set on the door lock body 10 and is transmission-connected with the lock buckle 11, the card plate switch 22 is set on the door lock body 10, and the card plate 21 selectively opens and closes the card plate switch 22, the stop plate assembly 30 can mainly include a stop plate 31 and a stop plate switch 32, the stop plate 31 can be rotatably set on the door lock body 10 and is transmission-coordinated with the card plate 21, the stop plate switch 32 is set on the door lock body 10, and the stop plate 31 selectively opens and closes the stop plate switch 32, the controller 40 is electrically connected to the card plate switch 22 and the stop plate switch 32 respectively, and the card plate switch 22 and the stop plate switch 32 are set in parallel.

[0040] Specifically, by rotatably arranging the card plate 21 and the stop plate 31 on the door lock body 10, the card plate 21 is transmission-connected with the lock buckle 11, and the stop plate 31 is transmission-coordinated with the card plate 21. On the one hand, when closing the door, the lock buckle 11 switches from the unlocked position to the locked position, and the lock buckle 11 drives the card plate 21 to rotate, and the card plate 21 further transmission-coordinated with the stop plate 31. The stop plate 31 can limit the return of the card plate 21 to ensure the stability and reliability of the lock buckle 11 when it is in the unlocked position. On the other hand, when opening the door, the stop plate 31 can be driven to release the transmission cooperation between the stop plate 31 and the card plate 21, and the card plate 21 returns, driving the lock buckle 11 to switch from the locked position to the unlocked position, thereby making the structure of the door lock 100 simpler and more reliable, and making the switching of the lock buckle 11 between the unlocked position and the locked position simpler and more reliable.

[0041] Furthermore, by setting a card plate switch 22 on the door lock body 10, when the card plate 21 rotates, the card plate 21 can selectively close the card plate switch 22, so that the open and closed state of the card plate switch 22 can be determined by the position of the card plate 21, and the position of the card plate 21 is determined by the position of the lock buckle 11, that is: the open and closed state of the card plate switch 22 is determined by the position of the lock buckle 11, and by electrically connecting the controller 40 to the card plate switch 22, the controller 40 can obtain whether the lock buckle 11 is in the locked position or the unlocked position through the open and closed state of the card plate switch 22, that is: the car door signal can be obtained and displayed on the dashboard, so that the user can quickly identify the locked state of the car door.

[0042] Due to the influence of switch manufacturing errors and component errors, and to ensure that the trigger point of the switch signal maintains a certain distance from the locking zero point, the card switch 22 has a conversion interval. In this interval, the card switch 22 may be squeezed or not squeezed, so that the door signal cannot be accurately identified only by the card switch 22. By adding the stop plate switch 32, the stop plate 31 selectively opens and closes the stop plate switch 32, so that the open and closed state of the stop plate 31 can be determined by the position of the stop plate 31, and the stop plate The position of 31 is determined by the position of the lock buckle 11, that is, the open and closed state of the stop plate switch 32 is determined by the position of the lock buckle 11, and by making the controller 40 electrically connected to the card plate switch 22 and the stop plate switch 32 respectively, the card plate switch 22 and the stop plate switch 32 are arranged in parallel, so that the controller 40 can directly obtain whether the lock buckle 11 is in the locked position or the unlocked position through the on and off of the parallel circuit where the card plate switch 22 and the stop plate switch 32 are located, that is, the door signal can be obtained and displayed on the dashboard.

[0043] On the one hand, different from the prior art in which the door signal is obtained only by the opening and closing state of the card plate switch, the door signal can be obtained through the card plate switch 22 and the stop plate switch 32 at the same time, which can increase the accuracy of the controller 40 in identifying the door signal and ensure the consistency between the door signal identification and the actual locking state of the door. On the other hand, the controller 40 can directly identify the door signal through the on-off state of the circuit signal where the card plate switch 22 and the stop plate switch 32 are located, which can make the identification of the door signal simpler.

[0044] Therefore, by making the card plate 21 selectively open and close the card plate switch 22, making the stop plate 31 selectively open and close the stop plate switch 32, and making the controller 40 electrically connected to the card plate switch 22 and the stop plate switch 32 respectively, the card plate switch 22 and the stop plate switch 32 are arranged in parallel, so that the stop plate switch 32 and the card plate switch 22 can work together, thereby improving the accuracy of the controller 40 in identifying the door signal, and making it easier for the controller 40 to identify the door signal.

[0045] Combination Figure 1-Figure 3 As shown, the card plate switch 22 is arranged on the side of the card plate 21 away from the stop plate 31, and the card plate 21 selectively squeezes the card plate switch 22 to make the card plate switch 22 selectively open and close, and the stop plate switch 32 is arranged on the side of the stop plate 31 away from the card plate 21, and the stop plate 31 selectively squeezes the stop plate switch 32 to make the stop plate switch 32 selectively open and close.

[0046] Specifically, the card board switch 22 is arranged on the side of the card board 21 away from the stop plate 31, and a dial shaft 212 can be arranged on the card board 21, so that when the card board 21 rotates, the card board 21 can drive the dial shaft 212 to rotate, and the dial shaft 212 can selectively squeeze the card board switch 22 to achieve the selective opening and closing of the card board switch 22, thereby making the selective cooperation between the card board 21 and the card board switch 22 simpler and more reliable, and making the selective opening and closing of the card board switch 22 by the card board 21 simpler and more reliable.

[0047] Furthermore, the stop plate switch 32 is arranged on the side of the stop plate 31 away from the card plate 21, and a protrusion can be arranged on the side of the stop plate 31 away from the card plate 21, so that when the stop plate 31 rotates, the protrusion can selectively squeeze the stop plate switch 32, so as to realize the selective opening and closing of the stop plate switch 32 by the stop plate 31, thereby making the selective coordination between the stop plate 31 and the stop plate switch 32 simpler and more reliable, and making the selective opening and closing of the stop plate switch 32 by the stop plate 31 simpler and more reliable.

[0048] In addition, the card plate switch 22 is set on the side of the card plate 21 away from the stop plate 31, and the stop plate switch 32 is set on the side of the stop plate 31 away from the card plate 21. In this way, the setting positions of the card plate switch 22, the card plate 21, the stop plate 31 and the stop plate switch 32 can be optimized, so that when the card plate 21 and the stop plate 31 are in transmission coordination, the card plate switch 22 and the stop plate switch 32 can be naturally squeezed correspondingly, or the squeezing of the card plate switch 22 and the stop plate switch 32 can be released correspondingly.

[0049] Combination Figure 2 and Figure 3 As shown, a first buckle 211 is provided on one side of the clamping plate 21 facing the stop plate 31 , and a second buckle 311 is provided on one side of the stop plate 31 facing the clamping plate 21 . The first buckle 211 and the second buckle 311 are engaged with each other.

[0050] Specifically, by setting a first buckle 211 on the side of the card plate 21 facing the stop plate 31, setting a second buckle 311 on the side of the stop plate 31 facing the card plate 21, and setting a first torsion spring 213 on the rotating axis of the card plate 21, and setting a second torsion spring 313 on the rotating axis on the stop plate 31, the first torsion spring 213 and the second torsion spring 313 can store elastic potential energy when the first buckle 211 and the second buckle 311 are engaged, and release the elastic potential energy when the first buckle 211 and the second buckle 311 are released from the engagement.

[0051] When the lock buckle 11 is in the locked position, the first buckle 211 and the second buckle 311 are engaged with each other, and the stop plate 31 can limit the rotation of the card plate 21, thereby ensuring the stability of the lock buckle 11 in the locked position, and at this time the card plate 21 squeezes the card plate switch 22, and the stop plate 31 correspondingly squeezes the stop plate switch 32.

[0052] When unlocking, the stop plate 31 can be electrically driven to rotate clockwise, and the second buckle 311 releases the snap fit with the first buckle 211. The card plate 21 rotates counterclockwise under the action of the first torsion spring 213, and then the electrical drive of the stop plate 31 is canceled. The stop plate 31 rotates counterclockwise under the action of the second torsion spring 313, and the bottom of the first buckle 211 abuts against the top of the second buckle 311. During this process, the lock buckle 11 is in the unlocked position, and the card plate 21 gradually releases the squeeze on the card plate switch 22. The stop plate 31 releases the card plate switch 22 when electrically driven, and squeezes the stop plate switch 32 again after rotation.

[0053] When locking, the lock buckle 11 can drive the card plate 21 to rotate clockwise, and the bottom of the first card buckle 211 abuts against the top of the second card buckle 311. The card plate 21 pushes the stop plate 31 to rotate clockwise until the bottom of the first card buckle 211 passes over the top of the second card buckle 311, and the second card buckle 311 rotates under the action of the second torsion spring 313, so that the first card buckle 211 and the second card buckle 311 are engaged with each other, and the lock buckle 11 reaches the locked position. During this process, the card plate 21 gradually approaches and squeezes the card plate switch 22, and the stop plate 31 does not squeeze the stop plate switch 32 until the lock buckle 11 reaches the locked position and the stop plate 31 squeezes the stop plate switch 32.

[0054] In this way, through the snap-fitting cooperation of the first snap buckle 211 and the second snap buckle 311, selective transmission cooperation between the card plate 21 and the stop plate 31 can be achieved, making the structure of the door lock 100 simpler and more reliable, and ensuring the normal unlocking and normal locking of the door lock 100.

[0055] Combination Figure 5As shown, the control method of the vehicle door lock 100 according to the present invention may mainly include the following steps: according to the position of the lock buckle 11, the card plate switch 22 and the stop plate switch 32 respectively determine their own open and closed states; according to the open and closed states of the card plate switch 22 and the open and closed states of the stop plate switch 32, the controller 40 obtains the door signal.

[0056] Specifically, when the vehicle door lock 100 is working, first, the actual position of the lock buckle 11 corresponds to the open and closed state of the card plate switch 22, and the open and closed state of the stop plate switch 32, so that the card plate switch 22 can determine its own open and closed state according to the actual position of the lock buckle 11, and the stop plate switch 32 can determine its own open and closed state according to the position of the lock buckle 11. Then, since the card plate switch 22 and the stop plate switch 32 are electrically connected to the controller 40 respectively, and the card plate switch 22 and the stop plate switch 32 are arranged in parallel, the on and off state of the parallel circuit of the card plate switch 22 and the stop plate switch 32 can be determined according to the open and closed state of the card plate switch 22 and the open and closed state of the stop plate switch 32. The controller 40 can directly obtain the door signal according to the on and off signal of the parallel circuit, which can make the door signal obtained by the controller 40 more accurate and the process of the controller 40 obtaining the door signal is simpler.

[0057] Combination Figure 6 As shown, the steps of obtaining the door signal of the controller 40 according to the open and closed states of the card plate switch 22 and the open and closed states of the stop plate switch 32 can mainly include: when the card plate switch 22 and the stop plate switch 32 are both in the closed state, the controller 40 obtains the door lock signal; when at least one of the card plate switch 22 and the stop plate switch 32 is in the open state, the controller 40 obtains the door unlock signal.

[0058] Specifically, in the step of the controller 40 acquiring the door signal according to the open and closed state of the card plate switch 22 and the switch state of the stop plate switch 32, if the card plate switch 22 and the stop plate switch 32 are both in the closed state, that is, the card plate switch 22 is squeezed by the card plate 21, and the stop plate switch 32 is squeezed by the stop plate 31, it means that the lock buckle 11 reaches the locking position at this time and the door is in the locked state, and the card plate switch 22 is squeezed by the card plate 21, the card plate switch 22 is disconnected, and the stop plate switch 32 is squeezed by the stop plate 31, the stop plate switch 32 is disconnected, so that the parallel circuit where the card plate switch 22 and the stop plate switch 32 are located can be connected, and the controller 40 receives the signal that the circuit is connected, that is, the controller 40 can obtain the door locking signal, and then when the door is actually in the locked state, the accuracy of the door signal obtained by the controller 40 can be guaranteed.

[0059] Furthermore, in the step of the controller 40 acquiring the door signal according to the open and closed state of the card board switch 22 and the switch state of the stop plate switch 32, if at least one of the card board switch 22 and the stop plate switch 32 is in the open state, that is, at least one of the card board switch 22 and the stop plate switch 32 is in an unpressed state, it means that the lock buckle 11 is in the unlocked position at this time and the door is not locked. In addition, the card board switch 22 and the stop plate switch 32 are arranged in parallel, and at least one of the card board switch 22 and the stop plate switch 32 is in an unpressed state. The circuit where the unpressed one of the card board switch 22 and the stop plate switch 32 is located is connected, so that the parallel circuit where the card board switch 22 and the stop plate switch 32 are located can be connected, and the controller 40 receives the signal that the circuit is connected, that is, the controller 40 can obtain the signal that the door is not locked, so that for different unlocking positions of the lock buckle 11, the controller 40 can obtain the signal that the door is not locked, and the accuracy of the door signal obtained by the controller 40 can be guaranteed.

[0060] Combination Figure 7 As shown, according to the position of the lock buckle 11, the card plate switch 22 and the stop plate switch 32 respectively determine their own open and closed states. According to the open and closed states of the card plate switch 22 and the open and closed states of the stop plate switch 32, the step of the controller 40 obtaining the door signal includes: when the lock buckle 11 is in the locked position, the card plate switch 22 is in the closed state, the stop plate switch 32 is in the closed state, and the controller 40 obtains the door locking signal.

[0061] Specifically, when the door lock 100 is working, when the lock buckle 11 is in the locked position, the card plate 21 presses the card plate switch 22, the card plate switch 22 is in the closed state, and the stop plate 31 presses the stop plate switch 32, and the stop plate 31 is in the closed state. Further, the card plate switch 22 is in the closed state, the card plate switch 22 is disconnected, the stop plate switch 32 is in the closed state, and the stop plate switch 32 is disconnected, so that the parallel circuit where the card plate switch 22 and the stop plate switch 32 are located is disconnected, and the controller 40 receives a signal of circuit disconnection, that is, the controller 40 can obtain a signal that the door is locked.

[0062] Combination Figure 8 As shown, according to the position of the lock buckle 11, the card plate switch 22 and the stop plate switch 32 respectively determine their own open and closed states. According to the open and closed states of the card plate switch 22 and the open and closed states of the stop plate switch 32, the step of the controller 40 obtaining the door signal may include: when the distance between the position of the lock buckle 11 and the locking position is greater than a first preset value and not greater than a second preset value, the card plate switch 22 is in a closed state, the stop plate switch 32 is in an open state, and the controller 40 obtains a door unlocked signal.

[0063] Specifically, when the door lock 100 is working, when the distance between the position of the lock buckle 11 and the locking position is greater than the first preset value and not less than the second preset value, the card plate 21 still squeezes the card plate switch 22, and the card plate switch 22 is in the closed state, and the stop plate 31 does not squeeze the stop plate switch 32, and the stop plate switch 32 is in the open state.

[0064] Furthermore, the card switch 22 is in the closed state, the card switch 22 is disconnected, the stop plate switch 32 is in the open state, and the stop plate switch 32 is turned on, so that the parallel circuit where the card switch 22 and the stop plate switch 32 are located can be connected, and the controller 40 receives the signal that the circuit is connected, that is: the controller 40 can obtain the signal that the vehicle door is not locked.

[0065] Combination Fig. 9 As shown, according to the position of the lock buckle 11, the card plate switch 22 and the stop plate switch 32 respectively determine their own open and closed states. According to the open and closed states of the card plate switch 22 and the open and closed states of the stop plate switch 32, the step of the controller 40 obtaining the door signal may also include: when the distance between the position of the lock buckle 11 and the locking position is greater than the second preset value and not greater than the third preset value, the card plate switch 22 is in the closed or open state, and the stop plate switch 32 is in the open state, the controller 40 obtains the door unlocked signal.

[0066] Specifically, when the door lock 100 is working, when the distance between the position of the lock buckle 11 and the locking position is greater than the second preset value and not greater than the third preset value, the card plate 21 may squeeze the card plate switch 22, or may not squeeze the card plate switch 22, corresponding to the card plate switch 22 being in the closed state or the open state, the stop plate 31 does not squeeze the stop plate switch 32, and the stop plate switch 32 is in the open state.

[0067] Furthermore, the card board switch 22 is in a closed state or an open state, the card board switch 22 is disconnected or connected, the stop plate switch 32 is in an open state, and the stop plate switch 32 is connected, so that the parallel circuit where the card board switch 22 and the stop plate switch 32 are located can be connected, and the controller 40 receives the signal that the circuit is connected, that is, the controller 40 can obtain the signal that the vehicle door is not locked.
