[0047] Embodiment 1

[0048] See also Figures 1 to 13 As shown, a door lock provided by an embodiment of the present invention comprises: a driving mechanism and a switch mechanism; the driving mechanism comprises an opening arm 101 and a toggle wheel 102, the rotation of the toggle wheel 102 can make the opening arm 101 swing, wherein the toggle wheel 102 comprises a gear portion 103 and a pushing portion connected to the gear portion 103, the pushing portion is used to push the opening arm 101 to swing; the switch mechanism comprises a stop claw 104 and a clamping plate 105 matched with the stop claw 104; the swing of the opening arm 101 can drive the stop claw 104 to swing. The door lock can be used in vehicles such as cars, and can also be installed in other non-vehicle occasions where the door lock may be used as needed.

[0049] Specifically, the door lock provided in this embodiment may also include a lock shell 106, the opening arm 101 is rotatably mounted on the lock shell 106, the stopping claw 104 and the card plate 105 are rotatably mounted on the lock shell 106, and optionally, the stopping claw 104 and the card plate 105 are located on one side of the lock shell 106, and the opening arm 101 and the toggle wheel 102 are located on the other side opposite to the lock shell 106. For the convenience of description, the side of the lock shell 106 where the opening arm 101 and the toggle wheel 102 are located is the front side of the shell, and the side of the lock shell 106 where the stop claw 104 and the card plate 105 are located is the back side of the shell; when viewed from the front side of the shell, the lock shell 106 is equipped with a first torsion spring 107 for enabling the opening arm 101 to swing clockwise, the lock shell 106 is also equipped with a second torsion spring 108 for enabling the stop claw 104 to swing counterclockwise, and the lock shell 106 is also equipped with a third torsion spring 109 for enabling the card plate 105 to rotate clockwise, so that the stop claw 104 has the function of being able to abut against the card plate 105, thereby realizing the half lock and full lock of the door lock. The clockwise and counterclockwise provided in this embodiment are all based on the observation from the front side of the shell. The gear part 103 can realize gear transmission, and the pushing part integrally connected with the gear part 103 facilitates the pushing of the opening arm 101; the pushing part is located on one side of the gear part 103. The swing of the stop claw 104 locks and limits the rotation of the card plate 105, so that the door lock has the functions of half locking and full locking. After the stop claw 104 releases the locking limit on the card plate 105, the opening function of the door lock (i.e., unlocking the door lock) is realized, that is, the door of the car can be opened.

[0050] The door lock provided by the embodiment of the present invention, in which the toggle wheel 102 adopts the gear part 103 to facilitate achieving higher transmission efficiency, which is beneficial to reducing the probability of failure to open the door lock. In addition, the pushing part connected to the gear part 103 can rotate with the gear part 103 when the gear part 103 rotates. The pushing part pushes the opening arm 101 to swing, so as to drive the stopping claw 104 to move, thereby realizing the opening of the door lock. In this way, the cooperation between the opening arm 101 and the toggle wheel 102 can improve the success rate of opening the door lock to a certain extent, and can ensure the reliability of the door lock when it is locked to a certain extent.

[0051] In an alternative solution of this embodiment, the opening arm 101 includes a bifurcated portion and a pushing portion 120 connected to the bifurcated portion; the bifurcated portion is provided with a first limiting groove 113, so that the bifurcated portion forms a first bifurcation 111 and a second bifurcation 112; the pushing portion 120 can be in contact with the locking pawl 104; the bifurcated portion is arranged in cooperation with the pushing portion; the rotation axis of the dial wheel 102 and the swing axis of the opening arm 101 can be arranged in parallel. A first pushing column 114 is connected to the locking pawl 104, and the pushing portion 120 can push the first pushing column 114 to move, so that the locking pawl 104 swings. The first pushing column 114 is fixed to the locking pawl 104. The dial wheel 102 applies a force to the bifurcated portion, so that the opening arm 101 swings against the torsion of the first torsion spring 107. When the opening arm 101 swings, the pushing portion 120 can apply a force to the first pushing column 114, so that the locking pawl 104 rotates clockwise against the torsion of the second torsion spring 108, so as to release the locking and limiting of the locking pawl 104 on the clamping plate 105; when the clamping plate 105 loses the locking and limiting of the locking pawl 104, the clamping plate 105 can rotate clockwise under the action of the third torsion spring 109.

[0052] Specifically, the bifurcated portion and the pushing portion 120 are integrally connected; the end face of the pushing portion 120 has a third arc-shaped depression, so that the first pushing column 114 can cooperate with the third arc-shaped depression, so that the pushing portion 120 can better apply a force to the first pushing column 114, so that the locking pawl 104 swings, and through the third arc-shaped depression, to a certain extent, it can be ensured that when the opening arm 101 applies a force to the first pushing column 114, the first pushing column 114 can always be in the third arc-shaped depression, improving the opening success rate of the door lock.

[0053] In an alternative solution of this embodiment, the pushing portion includes two cylinders 115 symmetrically arranged with respect to the axis of the gear portion 103. One of the cylinders 115 is limited in the first limiting groove 113. The rotation of the gear portion 103 enables the cylinder 115 located in the first limiting groove 113 to apply a force to the opening arm 101, so that the opening arm 101 can swing. The pushing portion further includes a wheel shaft portion, and the wheel shaft portion is hollow, so that after an installation shaft passes through the gear portion 103 and the wheel shaft portion, the installation shaft is installed on the lock case 106, so that the dial wheel 102 can rotate relative to the installation shaft. The wheel shaft portion and the two cylinders 115 can be distributed on the same diameter of the gear portion 103. Both the first bifurcation 111 and the second bifurcation 112 are provided with a first arc-shaped depression and a second arc-shaped depression, and the first arc-shaped depression is located between the first limiting groove 113 and the second arc-shaped depression, which is beneficial to reducing the interference of the wheel shaft portion of the pushing portion on the opening arm 101.

[0054] In an alternative embodiment of this example, the drive mechanism further includes a power assembly for driving the gear portion 103 to rotate; the power assembly includes a motor 116, a worm 117, and a worm gear structure 118; the motor 116 drives the worm 117 to rotate, the worm 117 meshes with the worm gear structure 118, and the worm gear structure 118 meshes with the gear portion 103. The worm gear structure 118 includes a first tooth portion and a second tooth portion connected to the first tooth portion, the first tooth portion meshes with the worm 117, and the second tooth portion meshes with the gear portion 103. The cooperation of the worm 117 and the worm gear structure 118 can improve the transmission efficiency and is beneficial to improving the success rate of opening the door lock.

[0055] Specifically, the motor 116 is installed on the lock housing 106 and is located on the front of the housing; the worm gear structure 118 is installed on the lock housing 106 and is located on the front of the housing. A worm 117 is installed on the output shaft of the motor 116; the first tooth portion and the second tooth portion can be integrally connected; the second tooth portion is located above the first tooth portion. The motor 116 drives the worm 117 to rotate, the worm 117 causes the first tooth portion to rotate. Since the first tooth portion and the second tooth portion are of an integral structure, the second tooth portion rotates together with the first tooth portion. The rotation of the second tooth portion drives the rotation of the gear portion 103, and the rotation of the gear portion 103 drives the pushing portion to rotate around the rotation axis of the gear portion 103, and the pushing portion then drives the opening arm 101 to swing.

[0056] It should be noted that the motor 116 can be a servo motor 116, and an angle sensor or an encoder can be installed on the motor 116 so that the motor 116 rotates a corresponding number of turns to achieve the rotation of the dial 102 by a corresponding angle. In addition, the helix angle of the worm can be made smaller than the equivalent friction angle between the worm and the teeth of the first tooth portion to achieve self-locking. In this way, when the motor 116 is not powered on and rotating, it can prevent the opening arm 101 from rotating and driving the dial 102 to rotate under the action of the first torsion spring 107.

[0057] In the optional solution of this embodiment, the opening arm 101 also includes a main body 119, and the two ends of the main body 119 are respectively connected to the bifurcated part and the push part 120 in an integral manner; the main body 119 has a limiting protrusion 121 extending in the direction of the reverse side of the shell, and the limiting protrusion 121 is used to limit the rotation angle of the opening arm 101, that is, to limit the maximum angle of the counterclockwise swing of the opening arm 101. In this way, since the maximum swing angle of the opening arm 101 is fixed, the maximum angle of the clockwise swing of the stop claw 104 is also fixed. The limiting protrusion 121 can be stopped by the stop part provided on the lock shell 106, so as to achieve the maximum angle limit of the opening arm 101. In addition, in order to reduce the noise generated by the collision of the limiting protrusion 121 of the opening arm 101 with the lock shell 106, a first buffer pad 122 can be provided on the lock shell 106. The contact between the limiting protrusion 121 and the first buffer pad 122 can greatly reduce the sound; the material of the first buffer pad 122 can be rubber, silicone or an elastic material.

[0058] In the optional solution of this embodiment, the stop claw 104 includes a ratchet portion 123 and a counterweight limiting portion 124, and the connection between the ratchet portion 123 and the counterweight limiting portion 124 is configured as the swing center of the stop claw 104; the clamping plate 105 has a first locking portion 125 and a second locking portion 126; the ratchet portion 123 can abut against the first locking portion or the second locking portion 126; the counterweight limiting portion 124 is used to limit the swing of the stop claw 104. The counterweight limiting portion 124 can also reduce the shaking of the stop claw 104 when it swings, thereby avoiding the stop claw 104 from being separated from the clamping plate 105 due to the shaking, which causes the failure of the limit locking of the clamping plate 105, and can ensure the reliability of the door lock when it is locked to a certain extent.

[0059] Specifically, the lock housing 106 is provided with a second limiting member 127 for limiting the maximum counterclockwise rotation angle of the stop claw 104, which is conducive to ensuring that when the stop claw 104 abuts against the first locking portion 125, that is, when the door lock is in a fully locked state, the position where the stop claw 104 abuts against the first locking portion 125 remains fixed, and in addition, the first push column 114 can be prevented from applying force to the opening arm 101. The second limiting member 127 can abut against the counterweight limiting portion 124, thereby limiting the maximum counterclockwise rotation angle of the stop claw 104. The second limiting member 127 can be a part of the lock housing 106 or an independent component, and its material can be rubber, silicone or other materials with a certain elasticity, which is conducive to reducing the noise generated when the counterweight limiting portion 124 collides with the second limiting member 127.

[0060] The pallet 105 has a lock slot 129 with an open end, and when the lock catch 201 installed on the vehicle body enters the lock slot 129, the door can be locked. The pallet 105 has a gear position portion 130, and a third limiting member 128 is provided on the lock housing 106. In this way, the gear position portion 130 and the third limiting member 128 cooperate to limit the maximum clockwise rotation angle of the pallet 105. The third limiting member 128 can be a part of the lock housing 106 or an independent component, and its material can be rubber, silicone or other materials with certain elasticity, which is beneficial to reducing the noise generated when the gear position portion 130 collides with the third limiting member 128. The first locking portion 125 and the gear position portion 130 are arranged alternately to form the lock slot 129. When the locking pawl 104 abuts against the first locking portion 125, the full-lock state of the door lock is achieved, and when the locking pawl 104 abuts against the second locking portion 126, the half-lock state of the door lock can be achieved.

[0061] In an optional solution of this embodiment, a positioning boss 131 is provided on the surface of the pallet 105, and the positioning boss 131 passes through the lock housing 106 and extends to the front of the housing; a first contact sensor 132 and a second contact sensor 133 are provided on the lock housing 106. The first contact sensor 132 and the second contact sensor 133 are arranged at intervals and are located on the front of the housing; when both the first contact sensor 132 and the second contact sensor 133 abut against the positioning boss 131, it is used to feedback that the door lock is in the open state; when only the second contact sensor 133 abuts against the positioning boss 131, it is used to feedback that the door lock is in the half-lock state; when neither the first contact sensor 132 nor the second contact sensor abuts against the positioning boss 131, it is used to feedback that the door lock is in the full-lock state. The first contact sensor 132 is used to detect whether it enters the half-lock state currently, and the second contact sensor 133 is used to detect whether it enters the full-lock state currently. After the second contact sensor 133 is triggered (i.e., it represents the current full-lock state), the vehicle ECU controls the motor to stop working or reverse. Both the first contact sensor 132 and the second contact sensor 133 can be microswitches. The first contact sensor 132 and the second contact sensor 133 can also prevent snow load, that is, to avoid the situation that the door automatically closes again after losing force when the door is opened.

[0062] In an alternative solution of this embodiment, the switch mechanism further includes a release arm 134 configured to be able to pull the detent 104 to swing the detent 104; a strip-shaped groove 135 extending along the length direction of the release arm 134 is formed at one end of the release arm 134, and the first push column 114 is inserted into the strip-shaped groove 135 and the first push column 114 can move along the length direction of the strip-shaped groove 135. The strip-shaped groove 135 can prevent the detent 104 from driving the inner opening mechanism and the outer opening mechanism to act during the process of unlocking with the motor 116. The release arm 134 can be used to pull the detent 104 through the inner opening mechanism or the outer opening mechanism to unlock the door lock.

[0063] Specifically, the release arm 134 is movably arranged on the lock case 106 and is located on the front surface of the lock case 106. One surface of the release arm 134 has a protruding projection 136, and the lock case 106 has a limiting groove 137 that cooperates with the protruding projection 136. The limiting groove 137 is in the shape of a curved long strip, so that the release arm 134 can move along the length extension direction of the limiting groove 137.

[0064] In an alternative solution of this embodiment, the door lock further includes an outer opening mechanism and an inner opening mechanism; the outer opening mechanism includes an outer opening rotating arm, the inner opening mechanism includes an inner opening rotating arm 138 and a wire 139, the wire 139 can make the inner opening rotating arm 138 rotate, and the inner opening rotating arm 138 can make the release arm 134 move through a connecting arm 140; the rotation of the outer opening rotating arm 145 can make the connecting arm 140 rotate to make the release arm 134 move. When the door lock is installed on the vehicle door, the outer opening mechanism can be used to open the door lock outside the vehicle to open the vehicle door, and the inner opening mechanism can be used to open the door lock inside the vehicle to open the vehicle door.

[0065] Specifically, the other end of the connecting arm 140 is hinged to one end of the release arm 134; the lock housing 106 is also provided with a fourth torsion spring 110 that enables the connecting arm 140 to rotate counterclockwise. The connecting arm 140 can be rotatably mounted on the lock housing 106, and the outward opening rotating arm can be rotatably mounted on the lock housing 106. The door lock can also include a lock cover 141, which is connected to the front side of the lock housing 106 by a fastener, such as a screw or a bolt. The inward opening rotating arm 138 is rotatably mounted on the lock cover 141. The door lock also includes a bottom cover 142, which is connected to the reverse side of the lock housing 106 by a fastener, such as a screw or a bolt. One end of the pull wire 139 is connected to the inner opening rotating arm 138. By pulling the pull wire 139, the inner opening rotating arm 138 rotates, and the inner opening rotating arm 138 drives the connecting arm 140 to rotate. The rotation of the connecting arm 140 drives the release arm 134 to move, and the release arm 134 then drives the stop claw 104 to move, so that the door lock is opened. The outer opening rotating arm is connected to the lock core 143, and a matching key can be inserted into the lock core 143. The key turns the lock core 143 to drive the outer opening rotating arm to rotate clockwise, and the outer opening rotating arm then drives the connecting arm 140 to rotate clockwise, thereby driving the release arm 134 to move, and the release arm 134 then drives the stop claw 104 to move, so that the stop claw 104 and the card plate 105 are disengaged, so that the door lock is opened, and then the car door can be opened. The first torsion spring 107, the second torsion spring 108, the third torsion spring 109 and the fourth torsion spring 110 can respectively realize that the components they act on are restored to the initial position.

[0066] The working principle of the door lock provided in this embodiment is:

[0067] Half-locked and fully-locked door lock: After the door lock is installed on the vehicle door, when the vehicle door is pushed to make the door lock contact with the lock catch on the vehicle body, after the lock catch enters the lock slot 129, during the rotation of the card plate 105, when the stop claw 104 engages with the second locking portion 126, the half-locked state of the door lock can be achieved, that is, the half-locked state of the vehicle door is achieved; when the vehicle door is continuously pushed to move, the card plate 105 continues to rotate, and when the stop claw 104 engages with the first locking portion 125, the full-locked state of the door lock can be achieved, that is, the full lock of the vehicle door is achieved. It should be noted that the locking state of the door lock can be fully locked or half-locked.

[0068] Electric opening: When the door lock is in the locked state, the stopping claw 104 and the card plate 105 are locked to the limit, that is, they are engaged. When the car door needs to be opened, the motor 116 is rotated, and the motor 116 drives the worm 117 to rotate. The worm 117 rotates the worm gear structure 118, and the worm gear structure 118 rotates the toggle wheel 102. The toggle wheel 102 causes the opening arm 101 to swing, and the opening arm 101 causes the stopping claw 104 to swing, so that the stopping claw 104 is disengaged from the card plate 105, and the card plate 105 rotates under the action of the third torsion spring 109, so that the door lock can be opened.

[0069] Outward opening: When the door lock is in the locked state, insert the matching key into the lock core 143. Turning the key rotates the lock core 143 clockwise, which drives the outward-opening rotating arm to rotate clockwise. The outward-opening rotating arm then drives the connecting arm 140 to rotate clockwise, thereby driving the release arm 134 to act. The release arm 134 then drives the detent 104 to act, so that the detent 104 disengages from the latch plate 105, thus realizing the opening of the door lock and then enabling the opening of the car door.

[0070] Inward opening: When the door lock is in the locked state, pull the cable 139 to rotate the inward-opening rotating arm 138. The inward-opening rotating arm 138 drives the connecting arm 140 to rotate. The rotation of the connecting arm 140 drives the release arm 134 to act, and the release arm 134 then drives the detent 104 to act, realizing the opening of the door lock.
