Description

Technical Field

[0001] The invention relates to the technical field of automobiles, and in particular to a door lock device which can be used for automobiles. Background Art

[0002] Car door locks are an important part of the car body. They are special parts that integrate safety, decoration and craftsmanship. With the development of the automobile industry, the functions and types of car door locks are becoming more and more diverse, and users' requirements for car comfort are getting higher and higher. The automatic opening and closing of car doors are getting more and more concerned by users and vehicle companies. More and more vehicle companies are starting to develop models with electric door functions. Electric doors not only meet the fashion pursuit of the majority of car enthusiasts, but also perfectly solve the embarrassment of the owner being unable to open the car door when both hands are holding items.

[0003] The electric suction door of a car in the prior art usually needs to be equipped with at least two motors to realize the functions of electric suction, electric release and unlocking. Specifically, the door lock structure is mainly composed of a lock body, a motor, a transmission mechanism, a locking mechanism and a control circuit. The two motors are usually responsible for the locking and unlocking functions of the door respectively. When the locking motor receives the command from the control circuit, it starts to work and generates a driving force. This driving force is transmitted to the locking mechanism through the transmission mechanism (such as gears, connecting rods, etc.), so that the locking mechanism locks the door. When unlocking is required, the unlocking motor starts to work and generates a reverse driving force, unlocking the locking mechanism through the transmission mechanism, thereby allowing the door to open.

[0004] However, in order to realize the two functions of electric attraction and electric release, the electric suction door in the prior art needs to have two sets of structures corresponding to electric attraction and electric release respectively, which leads to a complex door lock structure, occupies more installation space, and has a high cost. Summary of the invention

[0005] The purpose of the present invention is to solve the technical problem in the prior art that in order to realize the two functions of electric suction and electric release, the electric suction door of a car needs to have two sets of structures corresponding to electric suction and electric release respectively, which leads to a complex door lock structure, occupies more installation space and has high cost.

[0006] In order to solve the above technical problems, an embodiment of the present invention discloses a vehicle door lock device, including a lock core arranged on a vehicle body and a lock body structure arranged on a vehicle door.

[0007] The lock body structure includes a swing hook, a limit member, a driving member, and an intermediate transmission member connected to the driving member. The limit member is arranged on the side of the swing hook, and the limit member has a half-lock limit portion and a full-lock limit portion. The swing hook has a lock tongue matched with the lock core, and a limited portion matched with the half-lock limit portion and the full-lock limit portion.

[0008] Among them, in the process of closing the car door, the lock core pushes the swing hook to swing along the first direction so that the lock core gradually embeds into the lock tongue, and the limited part on the swing hook cooperates with the semi-locked limiting part on the limiting member, and the swing hook is in the semi-locked position.

[0009] The driving member drives the intermediate transmission member to swing the swing hook in conjunction, so that the limited part on the swing hook in the semi-locked position is disengaged from the semi-locked limiting part and cooperates with the fully locked limiting part on the limiting member, and the lock core is completely embedded in the lock tongue, and the swing hook is in the fully locked position.

[0010] Moreover, in the process of opening the vehicle door, the driving member drives the intermediate transmission member to move in conjunction with the limiting member, so that the limited part of the swing hook and the fully locked limiting part of the limiting member are separated, and the swing hook swings along a second direction opposite to the first direction to return to the initial state, and the lock core is disengaged from the lock tongue. The swing hook in the initial state is located in the unlocked position.

[0011] With the above technical solution, the door lock device includes a lock core mounted on the vehicle body and a lock tongue of a swing hook mounted on the door, thereby locking the door. The limiter is used to limit the position of the swing hook. The swing hook can be locked in the semi-locked position and the fully locked position respectively through the semi-locked limiter and the fully locked limiter on the limiter, thereby ensuring the stability of the swing hook movement.

[0012] When the lock core is gradually embedded in the lock tongue and the swing hook is restricted in the semi-locked position by the limiter, the driving member can drive the intermediate transmission member and further link the swing hook to swing, so that the lock core is completely embedded in the lock tongue and the swing hook is in the fully locked position, that is, the function of electric door closing is realized, and the restricted part of the swing hook is cooperated with the fully locked limiting part on the limiting member, which can avoid the swing hook from resetting and improve the locking stability between the lock core and the lock tongue.

[0013] During the door opening process, the driving member can drive the intermediate transmission member to move in conjunction with the limiting member, so that the limited part of the swing hook is disengaged from the fully locked limiting part of the limiting member, the swing hook returns to its initial state, and the lock core is disengaged from the lock tongue, thereby realizing the function of electric door opening.

[0014] In summary, the driving member of the vehicle door lock device drives the intermediate transmission member to not only link the swing hook to swing to achieve the function of electric door closing, but also link the limit member to move to achieve the function of electric door opening. Compared with the door lock structure in the prior art that has two sets of structures corresponding to electric attraction and electric release respectively, the structure of the vehicle door lock device is simple and the locking is reliable. The semi-locking limit part provided on the limit member can limit the swing hook to the semi-locking position, ensuring that when the driving member drives the intermediate transmission member to link the swing hook, the swing hook can accurately cooperate with the intermediate transmission member.

[0015] An embodiment of the present invention also discloses a vehicle door lock device, which also includes a controller, a half-lock position sensor component and a full-lock position sensor component. The half-lock position sensor component, the full-lock position sensor component and the drive component are respectively communicated with the controller, and the swing hook is provided with a half-lock transmission part and a full-lock transmission part.

[0016] Among them, in the process of closing the car door, when the limited part on the swing hook cooperates with the half-locked limiting part on the limiting part, the half-locked transmission part triggers the half-locked position sensing component, and the controller controls the driving part to drive the intermediate transmission part to link the swing hook to swing, and when the limited part on the swing hook cooperates with the fully-locked limiting part on the limiting part, the fully-locked transmission part triggers the fully-locked position sensing component, and the controller controls the driving part to stop driving.

[0017] By adopting the above technical scheme, through setting a half-lock position sensor component and a full-lock position sensor component, the position of the swing hook can be known more accurately. When the half-lock transmission part triggers the half-lock position sensor component, the controller controls the driving part to drive the intermediate transmission part to move, thereby realizing the function of electric door closing. When the full-lock transmission part triggers the full-lock position sensor component, the controller controls the driving part to stop driving, so as to avoid excessive movement of the swing hook caused by the intermediate transmission part, which may cause the limited part of the swing hook to hit the fully locked limit part on the limit part, thereby protecting the limit part.

[0018] An embodiment of the present invention also discloses a vehicle door lock device, in which a half-lock transmission part is configured as: a half-lock cam edge of a swing hook away from a side of a lock tongue, and a half-lock position sensing component includes: a half-lock signal push rod corresponding to the half-lock cam edge, a half-lock contact switch, and a half-lock signal swing rod arranged between the half-lock signal push rod and the half-lock contact switch, and one end of the half-lock signal swing rod is slidably connected to the half-lock signal push rod.

[0019] The half-lock cam pushes the half-lock signal push rod to make the half-lock signal swing rod swing, and the other end of the half-lock signal swing rod abuts against the half-lock contact switch, triggering the half-lock position sensor component.

[0020] The full lock transmission part is configured as: a full lock cam edge of the swing hook away from the side of the lock tongue, and the full lock position sensing component includes: a full lock signal push rod corresponding to the full lock cam edge, a full lock contact switch, and a full lock signal swing rod arranged between the full lock signal push rod and the full lock contact switch, and one end of the full lock signal swing rod is slidably connected to the full lock signal push rod.

[0021] The full-lock cam pushes the full-lock signal push rod to make the full-lock signal swing rod swing, and the other end of the full-lock signal swing rod abuts against the full-lock contact switch, triggering the full-lock position sensor component.

[0022] In addition, the half-locking cam edge and the full-locking cam edge are arranged at intervals, and a smoothly transitioned edge is formed between the half-locking cam edge and the full-locking cam edge.

[0023] By adopting the above technical scheme, during the door closing process, the swing hook swings along the first direction, the half-lock cam edge contacts the half-lock signal push rod first, and in the process of the swing hook gradually swinging, the half-lock cam edge pushes the half-lock signal push rod, and the half-lock signal swing rod forces the half-lock signal swing rod to swing during the movement until the swing hook is in the half-lock position, and the other end of the half-lock signal swing rod abuts against the half-lock contact switch, the half-lock position sensor component is triggered, and the controller controls the driving member to drive the intermediate transmission member to move, further pushing the swing hook to swing along the first direction. At this time, the full-lock cam edge contacts the full-lock signal push rod and pushes the full-lock signal push rod, causing the full-lock signal swing rod to swing until the swing hook is in the full-lock position, and the other end of the full-lock signal swing rod abuts against the full-lock contact switch, the full-lock position sensor component is triggered, and the controller controls the driving member to stop driving.

[0024] In addition, the half-lock cam edge and the fully-lock cam edge are arranged at intervals, so that the half-lock position sensor component and the fully-lock position sensor component are triggered at intervals, avoiding triggering the fully-lock position sensor component when the swing hook is in the half-lock position, and a smoothly transitioned edge is formed between the half-lock cam edge and the fully-lock cam edge, which helps to ensure that the sensor component can be triggered smoothly and accurately when the vehicle door transitions from a half-locked state to a fully-locked state (or vice versa).

[0025] The embodiment of the present invention further discloses a vehicle door lock device, wherein the intermediate transmission member is configured as a guide rod, and the guide rod is provided with a first pushing portion capable of pushing the swing hook and a second pushing portion capable of pushing the limit member at intervals along its axial direction.

[0026] A transmission wheel is arranged between the driving member and the guide rod, and a wheel groove is formed on the side wall of the transmission wheel. One end of the guide rod is slidably installed in the wheel groove.

[0027] During the door closing process, the driving member drives the transmission wheel to rotate, thereby linking the guide rod to move toward one side along its axial direction, and the first pushing part pushes the swing hook to swing, so that the swing hook swings from the half-locked position to the fully locked position.

[0028] During the door opening process, the driving member drives the transmission wheel to rotate, thereby linking the guide rod to move along its axial direction toward the other side, and the second pushing part pushes the limiting member, so that the swing hook moves from the fully locked position to the unlocked position.

[0029] By adopting the above technical solution, the door lock device drives the transmission wheel to rotate through the driving member, and the transmission wheel moves along the axial direction of the guide rod through the wheel groove linkage. Compared with the driving member with linear power output, this transmission structure saves the space occupied by the door lock device in the axial direction of the guide rod. In addition, the first pushing part and the second pushing part arranged on the guide rod are respectively used to push the swing hook and the limiter, ensuring that the swing hook and the limiter can be accurately acted on by the guide rod.

[0030] An embodiment of the present invention also discloses a vehicle door lock device, wherein the contour of the wheel groove can be divided into multiple functional areas along its circumference, and the multiple functional areas include: an unlocking area, a release area, and an engagement area. The distances between any two functional areas among the unlocking area, the release area, and the engagement area and the wheel center of the transmission wheel are different, and a transition zone with a smooth transition is formed between two adjacent functional areas.

[0031] Among them, one end of the guide rod moves from the unlocking area of ​​the wheel groove toward the attraction area, and the swing hook moves from the half-locked position to the full-locked position.

[0032] One end of the guide rod moves from the attraction area of ​​the wheel groove toward the release area, and the swing hook moves from the full lock position to the unlock position.

[0033] By adopting the above technical solution, the contour of the wheel groove is divided into an unlocking area, a release area and an engagement area along its circumference, and the distances between any two functional areas and the wheel center of the transmission wheel are different. Therefore, when one end of the guide rod slides from one of the functional areas to another functional area, the guide rod can be linked to move along its axial direction to achieve the corresponding function.

[0034] An embodiment of the present invention further discloses a vehicle door lock device, wherein the wheel groove has two unlocking areas, a release area and an engagement area, the two unlocking areas are arranged opposite to each other, the release area is arranged on one side of the two unlocking areas, and the engagement area is arranged on the other side of the two unlocking areas.

[0035] With the above technical solution, the wheel groove has two unlocking areas, a release area and a pull-in area, and after one end of the guide rod moves from the unlocking area to the release area to realize electric door opening, in order to facilitate subsequent door closing, the driving member can drive the transmission wheel to continue to rotate, so that one end of the guide rod moves from the release area to the unlocking area on the other side. Similarly, after realizing electric door closing, the driving member can also drive the transmission wheel to continue to rotate, so that one end of the guide rod moves from the pull-in area to the unlocking area on the other side. Therefore, the wheel groove of this structure is convenient for resetting the guide rod.

[0036] An embodiment of the present invention also discloses a vehicle door lock device, which also includes an unlock position sensor assembly electrically connected to the controller, the unlock position sensor assembly including an unlock signal push rod, an unlock contact switch, a lock contact switch, and an unlock signal swing rod arranged between the unlock signal push rod and the unlock contact switch and the lock contact switch, one end of the unlock signal swing rod is slidably connected to the unlock signal push rod, and the other end can swing between the unlock contact switch and the lock contact switch, and the guide rod is transmission-connected to the unlock signal push rod.

[0037] Among them, when one end of the guide rod is located in the attraction area of ​​the wheel groove and the swing hook is in the full lock position, the other end of the unlocking signal swing rod contacts the locking contact switch.

[0038] When one end of the guide rod is located in the unlocking area of ​​the wheel groove and the swing hook is located in the unlocking position, the other end of the unlocking signal swing rod contacts the unlocking contact switch.

[0039] By adopting the above technical solution, an unlocking position sensor component electrically connected to the controller is provided to facilitate detection of the position of the guide rod. The controller can control the drive member to adjust the position of the guide rod according to the feedback of the unlocking position sensor component.

[0040] The embodiment of the present invention further discloses a vehicle door lock device, wherein the first pushing part is configured as a pressure block extending radially outwardly along the guide rod, and the swing hook is formed with a boss for cooperating with the pressure block.

[0041] The second pushing part is configured as: a pendulum block extending radially outward along the guide rod, the limiting part is configured as: a limiting pendulum rod that can swing around its one end, the limiting pendulum rod is provided with a semi-locking limiting part and a fully-locking limiting part at intervals along its axial direction, the pendulum block can abut the other end of the limiting pendulum rod, so that the limiting pendulum rod swings around its one end.

[0042] By adopting the above technical solution, the pressure block on the guide rod can press the swing hook to swing along the second direction, and the swing block on the guide rod pushes the limit swing rod to swing, so that the limited part on the swing hook can be separated from the fully locked limit part on the limit swing rod. This structure allows the guide rod to transmit the swing hook and the limit swing rod separately, avoiding interference with the other component when the transmission is connected to one of them.

[0043] The embodiment of the present invention further discloses a vehicle door lock device, which further includes a handle pusher transmission-connected to the door handle.

[0044] In addition, the pendulum block is rotatably connected to the guide rod, and the handle pusher is arranged on the side of the pendulum block away from the limiting pendulum rod. The handle pusher pushes the pendulum block to rotate the pendulum block, thereby pushing the limiting pendulum rod to swing around one end thereof.

[0045] By adopting the above technical solution, a handle pusher is arranged in transmission connection with the door handle, so that passengers can manually open the door by pulling the door handle.

[0046] The embodiment of the present invention further discloses a vehicle door lock device, wherein the driving member is configured as: a rotating motor capable of bidirectional rotation, a worm is provided at the output end of the rotating motor, and the transmission wheel is configured as: a worm wheel transmission-connected to the worm.

[0047] By adopting the above technical solution, the rotating motor that can rotate in both directions can rotate forward and reverse through the worm gear linked to the worm, so that one end of the guide rod can move from the unlocking area to the release area, or from the unlocking area to the attraction area, thereby realizing electric door opening and electric door closing.

[0048] In addition, the transmission accuracy between the worm and the worm wheel is high, so the position of the guide rod can be controlled more accurately.

[0049] An embodiment of the present invention further discloses a car, comprising a vehicle body and a door arranged on the vehicle body, and the car further comprises any one of the above-mentioned door lock devices.

[0050] The above technical solution is adopted and the automobile is provided with the above door lock device. Since the door lock device realizes the functions of electric door opening and electric door closing only through a single drive member and an intermediate transmission member, the door lock device has a simple structure and occupies a small space in the door, which is beneficial to the arrangement of other structures in the door of the automobile. In addition, the control of the single drive member is simple, which reduces the difficulty of controlling the electric door opening and electric door closing of the automobile.

The limiter 220 is used to limit the position of the swing hook 210. The swing hook 210 can be locked in the semi-locked position (see FIG. 2 ) through the semi-locked limiter 221 and the fully locked limiter 222 on the limiter 220. Figure 4 ) and fully locked position (see Figure 7 ), thereby ensuring the stability of the swing hook 210 movement. In addition, the swing hook 210 is locked in the half-locked position, which is convenient for the triggering of the electric door closing process.

[0086] During the door closing process, when the lock core 100 is gradually embedded in the lock tongue 211 and the swing hook 210 is restricted in the semi-locked position by the limit member 220, the driving member 230 can drive the intermediate transmission member 240 and further link the swing hook 210 to swing, so that the lock core 100 is completely embedded in the lock tongue 211, and the swing hook 210 is in the fully locked position, that is, the function of electric door closing is realized, and the restricted part of the swing hook 210 is cooperated with the fully locked limit part 222 on the limit member 220, which can avoid the swing hook 210 from resetting and improve the locking stability between the lock core 100 and the lock tongue 211.

[0087] During the door opening process, the driving member 230 can drive the intermediate transmission member 240 to move in conjunction with the limiting member 220, so that the limited portion 212 of the swing hook 210 is disengaged from the fully locked limiting portion 222 of the limiting member 220, the swing hook 210 returns to its initial state, and the lock core 100 is disengaged from the lock tongue 211, thereby realizing the function of electric door opening.

[0088] In summary, the driving member 230 of the vehicle door lock device 10 drives the intermediate transmission member 240 to not only link the swing hook 210 to swing to achieve the function of electric door closing, but also link the limit member 220 to move to achieve the function of electric door opening. Compared with the door lock structure in the prior art that has two sets of structures corresponding to electric attraction and electric release respectively, the structure of the vehicle door lock device 10 is simple and the locking is reliable. The semi-locking limit part 221 provided on the limit member 220 can limit the swing hook 210 to the semi-locking position, ensuring that when the driving member 230 drives the intermediate transmission member 240 to link the swing hook 210, the swing hook 210 can accurately cooperate with the intermediate transmission member 240.

[0089] The specific structure for locking in the door lock device 10 will be described below.

[0090] The lock core 100 is a structure used to cooperate with the lock tongue 211 to achieve the locking function. Figure 2 As shown, in this embodiment, the lock core 100 is fixed on the vehicle body, and at a position corresponding to the lock tongue 211, the lock core 100 can be set as a pin, and of course a lock ring structure can also be set, which is not specifically limited in this embodiment.

[0091] The swing hook 210 is a structure movably arranged in the vehicle door. Figure 2 As shown, the swing hook 210 has one end (eg Figure 1 A lock tongue 211 with a groove is formed at the left end portion of the groove, and the side wall height on the left side of the groove is lower than the side wall height on the right side, so that during the door closing process, the lock core 100 can abut against the side wall on the right side of the groove, and then when the swing hook 210 is pushed to swing in the clockwise direction, the lock core 100 can gradually embed into the groove; during the door opening process, when the swing hook 210 swings in the counterclockwise direction, the lock core 100 can slide out from the left side of the groove more easily.

[0092] In addition, a limited portion 212 is provided on the swing hook 210 at intervals on the right side of the lock tongue 211. The limited portion 212 is specifically a columnar protrusion structure. One end of the swing hook 210 is rotatably sleeved on a rotating shaft in the door, so that the swing hook 210 can swing around the rotating shaft provided inside it, and a torsion spring is sleeved on the rotating shaft. When the swing hook 210 moves along the Figure 1 The torsion spring is twisted and deformed to provide a restoring force in the counterclockwise direction for the swing hook 210. It should be noted that Figure 1 The clockwise direction in is the first direction, Figure 1 The counterclockwise direction in is the second direction.

[0093] like Figure 1 As shown, the limiting member 220 is configured to be able to rotate around one end (such as Figure 1 The limit swing rod 2201 is swung at the left end of the swing rod and is located on the side where the lock tongue 211 is set. The limit swing rod 2201 is along the Figure 1 , and a half-locked limiting portion 221 and a fully-locked limiting portion 222 are axially spaced apart. The half-locked limiting portion 221 and the fully-locked limiting portion 222 are both configured as recesses matched with the limited portion 212, and an inclined extending guide surface is formed on the side wall of the half-locked limiting portion 221 close to the fully-locked limiting portion 222. The guide surface can guide the moving path of the limited portion 212, so that when the swing hook 210 swings in the clockwise direction, the limited portion 212 of the swing hook 210 can move toward the fully-locked limiting portion 222 after being disengaged from the half-locked limiting portion 221.

[0094] A compressible pressure rod 2202 is provided on the side of the limiting swing rod 2201 away from the swing hook 210, and the lower end of the pressure rod 2202 abuts against the other side of the limiting swing rod 2201, so that the limiting swing rod 2201 maintains a posture extending in the horizontal direction.

[0095] During the door closing process, the vehicle door gradually moves closer to the vehicle body, and the lock core 100 on the vehicle body abuts against the lock tongue 211 from the upper right side of the swing hook 210, so that the swing hook 210 swings in a clockwise direction around the internal rotating shaft, and the limited portion 212 on the swing hook 210 is respectively clamped with the half-locked limiting portion 221 and the fully locked limiting portion 222 on the limiting rocker 2201. When the lock core 100 is completely embedded in the lock tongue 211 of the swing hook 210, the vehicle door is completely locked, and the limited portion 212 on the swing hook 210 cooperates with the fully locked limiting portion 222 on the limiting rocker 2201 to prevent the swing hook 210 from swinging in a counterclockwise direction under the action of the torsion spring, causing the lock core 100 to slip out of the lock tongue 211.

[0096] During the door opening process, the transmission structure is used to make the limit rocker arm 2201 swing counterclockwise around its left end, the pressure rod 2202 is compressed, the limited portion 212 on the swing hook 210 is separated from the full lock limit portion 222 on the limit rocker arm 2201, and the rocker arm swings counterclockwise under the action of the torsion spring, so that the lock core 100 is separated from the lock tongue 211. After the unlocking is completed, the limit rocker arm 2201 is reset under the action of the pressure rod 2202.

[0097] Of course, the specific structure used for locking in the door lock device 10 is not limited to the structure of the above embodiment. Those skilled in the art can design it according to actual conditions and specific needs, and this embodiment does not make any specific limitations on this.

[0098] The specific structure of the vehicle door lock device 10 for realizing electric door opening and electric door closing will be described below.

[0099] like Figure 1 and Figure 3 As shown, in this embodiment, the intermediate transmission member 240 is set as a guide rod 241 extending in the vertical direction, and the guide rod 241 is provided with a first push portion 242 that can push the swing hook 210 and a second push portion 243 that can push the limiter 220 along its axial interval. Among them, the first push portion 242 is arranged in the middle of the guide rod 241, and the second push portion 243 is arranged in the upper part of the guide rod 241. It should be noted that in this embodiment, in order to ensure that the guide rod 241 can only move in the vertical direction, a sleeve (not shown in the figure) extending in the vertical direction is sleeved on the outer side of the guide rod 241 to limit the displacement of the guide rod 241 in other directions.

[0100] Optionally, in one embodiment, as Figure 3 As shown, the first pushing portion 242 is configured as a pressing block 244 extending radially outward from the guide rod 241 , and a boss 215 for cooperating with the pressing block 244 is formed on the swing hook 210 .

[0101] The second pushing portion 243 is configured as a pendulum block 245 extending radially outward along the guide rod 241, and the limiting member 220 is configured as a limiting pendulum rod 2201 that can swing around one end thereof, and the limiting pendulum rod 2201 is provided with a semi-locking limiting portion 221 and a fully-locking limiting portion 222 spaced apart along its axial direction, and the pendulum block 245 can abut against the other end of the limiting pendulum rod 2201, so that the limiting pendulum rod 2201 swings around one end thereof.

[0102] It should be noted that, in the present embodiment, the pressure block 244 arranged in the middle of the guide rod 241 is integrally formed with the guide rod 241, and the pendulum block 245 arranged on the upper part of the guide rod 241 is rotatably connected to the guide rod 241, that is, the pendulum block 245 is transferred to the guide rod 241 through a pin shaft, and a torsion spring is sleeved on the pin shaft. When the pendulum block 245 is in a natural state, its lower end is inclined toward the side of the limit pendulum rod 2201, and the upper end is inclined away from the limit pendulum rod 2201. When the pendulum block 245 translates upward or swings in the clockwise direction, the lower end of the pendulum block 245 will push the limit pendulum rod 2201 to swing.

[0103] The guide rod 241 moves downward in the axial direction, and the pressing block 244 on the guide rod 241 can press the swing hook 210 to swing in the clockwise direction, so that the lock core 100 is completely embedded in the lock tongue 211; while the guide rod 241 moves upward in the axial direction, and the swing block 245 on the guide rod 241 pushes the limit swing rod 2201 to swing in the counterclockwise direction, so that the limited portion 212 on the swing hook 210 can be separated from the full-locking limit portion 222 on the limit swing rod 2201. This structure allows the guide rod 241 to transmit the swing hook 210 and the limit swing rod 2201 respectively, avoiding interference with the other component when the transmission is connected to one of them.

[0104] like Figure 1 As shown, when other components act on the upper end of the pendulum block 245, such as a handle pusher 290 connected to the door handle, the handle pusher 290 can be a rod-shaped structure arranged on the right side of the guide rod 241 and can move in the vertical direction, and the handle pusher 290 is located above the upper end of the pendulum block 245. When the car door encounters a collision or needs to be opened manually, the driving member 230 will drive the guide rod 241 to move to the position shown in FIG. Fig. 9In the position shown, by pulling the door handle, the handle pusher 290 presses the upper end of the pendulum block 245 downward, so that the pendulum block 245 can swing in the clockwise direction, and its lower end close to the limit pendulum rod 2201 can push the limit pendulum rod 2201 to swing. When the handle pusher 290 no longer presses the pendulum block 245, the torsion spring can provide a counterclockwise restoring force for the pendulum block 245, so that the pendulum block 245 returns to a natural state. Of course, a driving structure controlled by the central control controller in the car can also be provided, and the driving structure is directly connected to the limit pendulum rod 2201 through transmission, so as to realize the function of opening the door through the central control, or a pulling structure connected to the inner handle of the door can be provided, and the pulling structure can swing the limit pendulum rod 2201 in conjunction with it, so as to realize the function of opening the door from the inside. Those skilled in the art can design it according to the actual situation and specific needs, and this embodiment does not make specific limitations on this.

[0105] In this embodiment, by providing a handle pusher 290 that is transmission-connected to the door handle, it is convenient for passengers to manually open the door by pulling the door handle.

[0106] Of course, the structure of the guide rod 241 used to transmit the swing hook 210 and the limit swing rod 2201 is not limited to the above-mentioned embodiment. In another replaceable embodiment, the first pushing portion 242 of the guide rod 241 is set as a first protruding structure extending radially outward, and the outer side wall of the first protruding structure is inclined outward from the lower end to the upper end. When the guide rod 241 moves axially downward, the outer side wall of the first protruding portion abuts against the boss 215 of the swing hook 210, so that the swing hook 210 swings in the clockwise direction; the second pushing portion 243 of the guide rod 241 is set as a second protruding structure extending radially outward, and the outer side wall of the second protruding structure extends outwardly from the upper end to the lower end. When the guide rod 241 moves axially upward, the outer side wall of the second protruding structure abuts against the right end of the limit swing rod 2201, so that the limit swing rod 2201 swings in the counterclockwise direction. Therefore, regarding the structure of the guide rod 241 for transmitting the swing hook 210 and the limiting swing rod 2201, those skilled in the art may design it according to actual conditions and specific needs, and this embodiment does not make any specific limitation on this.

[0107] Furthermore, in this embodiment, the driving member 230 is configured as a rotating motor 231 that can rotate in both directions, and a transmission wheel 250 is arranged between the driving member 230 and the guide rod 241, and a wheel groove 251 is formed on the side wall of the transmission wheel 250, and one end of the guide rod 241 is slidably installed in the wheel groove 251.

[0108] During the door closing process, the driving member 230 drives the transmission wheel 250 to rotate, thereby linking the guide rod 241 to move toward one side along its axial direction, and the first pushing portion 242 pushes the swing hook 210 to swing, so that the swing hook 210 swings from the semi-locked position to the fully locked position.

[0109] During the door opening process, the driving member 230 drives the transmission wheel 250 to rotate, thereby linking the guide rod 241 to move along its axial direction toward the other side, and the second pushing portion 243 pushes the limit member 220, so that the swing hook 210 moves from the fully locked position to the unlocked position.

[0110] The vehicle door lock device 10 drives the transmission wheel 250 to rotate through the driving member 230, and the transmission wheel 250 moves along the axial direction of the guide rod 241 through the wheel groove 251. Compared with the driving member 230 with linear power output, this transmission structure saves the space occupied by the vehicle door lock device 10 in the axial direction of the guide rod 241. In addition, the first pushing portion 242 and the second pushing portion 243 provided on the guide rod 241 are used to push the swing hook 210 and the limiter 220 respectively, ensuring that the swing hook 210 and the limiter 220 can be accurately acted on by the guide rod 241.

[0111] More specifically, Figure 3 As shown, the contour of the wheel groove 251 can be divided into multiple functional areas along its circumference, and the multiple functional areas include: an unlocking area 252, a release area 253 and an attraction area 254. The distances between any two functional areas among the unlocking area 252, the release area 253 and the attraction area 254 and the wheel center of the transmission wheel 250 are different, and a transition zone with a smooth transition is formed between two adjacent functional areas.

[0112] Among them, on the wheel groove 251, the wheel center distance between the release area 253 and the transmission wheel 250 is larger than the wheel center distance between the unlocking area 252 and the transmission wheel 250 and the wheel center distance between the attraction area 254 and the transmission wheel 250, and the wheel center distance between the unlocking area 252 and the transmission wheel 250 is larger than the wheel center distance between the attraction area 254 and the transmission wheel 250.

[0113] When one end of the guide rod 241 moves from the unlocking area 252 of the wheel groove 251 toward the suction area 254, the guide rod 241 moves vertically downward along the axial direction, and the pressure block 244 on the guide rod 241 presses the boss 215 on the swing hook 210, and the swing hook 210 moves from the semi-locked position to the fully locked position.

[0114] When one end of the guide rod 241 moves from the attraction area 254 of the wheel groove 251 toward the release area 253, the guide rod 241 moves vertically upward along the axial direction, the swing block 245 on the rod pushes the limit swing rod 2201 to swing, and the swing hook 210 moves from the fully locked position to the unlocked position.

[0115] Optionally, in this embodiment, if Figure 1 As shown, the wheel groove 251 has two unlocking areas 252 , a release area 253 and an attraction area 254 . The two unlocking areas 252 are arranged opposite to each other, the release area 253 is arranged on one side of the two unlocking areas 252 , and the attraction area 254 is arranged on the other side of the two unlocking areas 252 .

[0116] Among them, after one end of the guide rod 241 moves from the unlocking area 252 to the releasing area 253 to realize electric door opening, in order to facilitate the subsequent door closing, the driving member 230 can drive the transmission wheel 250 to continue to rotate, so that one end of the guide rod 241 moves from the releasing area 253 to the unlocking area 252 on the other side. Similarly, after the electric door is closed, the driving member 230 can also drive the transmission wheel 250 to continue to rotate, so that one end of the guide rod 241 moves from the suction area 254 to the unlocking area 252 on the other side. Therefore, the wheel groove 251 of this structure facilitates the reset of the guide rod 241.

[0117] It should be noted that the functional areas divided by the wheel groove 251 are not limited to the above-mentioned embodiment. In another replaceable embodiment, the wheel groove 251 has an unlocking area 252, a release area 253 and an attraction area 254. The three functional areas are adjacent to each other and connected to each other through a transition area. This embodiment does not make a sole limitation on this.

[0118] More specifically, in the present embodiment, a worm 232 is disposed at the output end of the rotary motor 231 , and the transmission wheel 250 is configured as a worm wheel 2501 transmission-connected to the worm 232 .

[0119] The bidirectionally rotatable rotary motor 231 is linked to the worm wheel 2501 through the worm 232 to rotate forward and reverse, so that one end of the guide rod 241 can move from the unlocking area 252 to the release area 253, and can also move from the unlocking area 252 to the pull-in area 254, thereby realizing electric door opening and electric door closing. In addition, the worm 232 and the worm wheel 2501 have a high transmission accuracy, so as to more accurately control the position of the guide rod 241.

[0120] Of course, the transmission method between the rotating motor 231 and the intermediate transmission member 240 is not limited to the above-mentioned embodiment. In another replaceable embodiment, the output end of the rotating motor 231 is directly connected to the transmission wheel 250, thereby directly driving the transmission wheel 250 to rotate. Alternatively, the output end of the rotating motor 231 is provided with a driving wheel, and the transmission wheel 250 is provided as a driven gear meshing with the driving gear.

[0121] In another embodiment, the driving member 230 is configured as a linear motor, and the output end of the linear motor is directly fixedly connected to the lower end of the guide rod 241, thereby linking the guide rod 241 to move in the vertical direction. Alternatively, the output end of the linear motor provides vertical power in the horizontal direction, and a transmission plate is provided at the output end of the linear motor, and a slide groove bending and extending in the horizontal direction is provided on the transmission plate, and the lower end of the guide rod 241 is slidably connected to the slide groove, and then when the linear motor drives the transmission plate to move in the horizontal direction, the lower end of the guide rod 241 slides in the slide groove, and causes the guide rod 241 to move in the vertical direction.

[0122] In order to trigger the electric door opening and closing functions more accurately, such as Figure 1 As shown, in this embodiment, the door lock device 10 further includes a controller (not shown in the figure), a half-lock position sensor assembly 260 and a full-lock position sensor assembly 270. The half-lock position sensor assembly 260, the full-lock position sensor assembly 270 and the drive member 230 are respectively connected to the controller for communication, and the swing hook 210 has a half-lock transmission part and a full-lock transmission part. It should be noted that the controller can be a control element used alone on the car to control the opening and closing of the car door, or it can be the overall control element of the car. Regarding the specific model and specification of the controller, those skilled in the art can design it according to the actual situation and specific needs, and this embodiment does not make specific restrictions on this.

[0123] Among them, in the process of closing the car door, when the limited part 212 on the swing hook 210 cooperates with the semi-locked limiting part 221 on the limiting member 220, the semi-locked transmission part triggers the semi-locked position sensing component 260, and the controller controls the driving member 230 to drive the intermediate transmission member 240 to link the swing hook 210 to swing, and when the limited part 212 on the swing hook 210 cooperates with the fully locked limiting part 222 on the limiting member 220, the fully locked transmission part triggers the fully locked position sensing component 270, and the controller controls the driving member 230 to stop driving.

[0124] In this embodiment, by providing a half-lock position sensor component 260 and a fully-lock position sensor component 270, the position of the swing hook 210 can be known more accurately. When the half-lock transmission part triggers the half-lock position sensor component 260, the controller controls the driving member 230 to drive the intermediate transmission member 240 to move, thereby realizing the function of electric door closing. When the fully-lock transmission part triggers the fully-lock position sensor component 270, the controller controls the driving member 230 to stop driving, so as to prevent the intermediate transmission member 240 from linking the swing hook 210 with excessive movement, thereby causing the limited portion 212 of the swing hook 210 to hit the fully-locked limited portion 222 on the limited member 220, thereby protecting the limited member 220.

[0125] Optionally, in this embodiment, if Figure 2 As shown, the half-lock transmission part is configured as a half-lock cam edge 213 on the side of the swing hook 210 away from the lock tongue 211, and the half-lock position sensing assembly 260 includes a half-lock signal push rod 261 corresponding to the half-lock cam edge 213, a half-lock contact switch 262, and a half-lock signal swing rod 263 arranged between the half-lock signal push rod 261 and the half-lock contact switch 262, one end of the half-lock signal swing rod 263 is slidably connected to the half-lock signal push rod 261, specifically, one end of the half-lock signal swing rod 263 is provided with a bar hole, and one end of the half-lock signal push rod 261 is provided with a protrusion adapted to and connected to the bar hole.

[0126] The half-lock cam edge 213 pushes the half-lock signal push rod 261 to make the half-lock signal swing rod 263 swing, and the other end of the half-lock signal swing rod 263 abuts against the half-lock contact switch 262, and the half-lock position sensor assembly 260 is triggered.

[0127] The full lock transmission part is configured as a full lock cam edge 214 on the side of the swing hook 210 away from the lock tongue 211, and the full lock position sensing assembly 270 includes a full lock signal push rod 271 corresponding to the full lock cam edge 214, a full lock contact switch 272, and a full lock signal swing rod 273 arranged between the full lock signal push rod 271 and the full lock contact switch 272, one end of the full lock signal swing rod 273 is slidably connected to the full lock signal push rod 271, specifically, the connection method between the full lock signal swing rod 273 and the full lock signal push rod 271 is similar to the connection method between the half lock signal swing rod 263 and the half lock signal push rod 261.

[0128] The full-lock cam edge 214 pushes the full-lock signal push rod 271 to make the full-lock signal swing rod 273 swing, and the other end of the full-lock signal swing rod 273 abuts against the full-lock contact switch 272, and the full-lock position sensor assembly 270 is triggered.

[0129] Furthermore, the half-locking cam edge 213 and the full-locking cam edge 214 are arranged at intervals, and a smoothly transitioned edge is formed between the half-locking cam edge 213 and the full-locking cam edge 214 .

[0130] During the door closing process, the swing hook 210 swings in the first direction, the half-lock cam edge 213 contacts the half-lock signal push rod 261 first, and during the gradual swinging of the swing hook 210, the half-lock cam edge 213 pushes the half-lock signal push rod 261, and the half-lock signal push rod 261 forces the half-lock signal swing rod 263 to swing during the movement until the swing hook 210 is in the half-lock position, and the other end of the half-lock signal swing rod 263 abuts against the half-lock contact switch 262, and the half-lock position sensor assembly 260 is triggered. The controller controls the driving member 230 to drive the intermediate transmission member 240 to move, further pushing the swing hook 210 to swing along the first direction. At this time, the full lock cam edge 214 contacts the full lock signal push rod 271, and pushes the full lock signal push rod 271, so that the full lock signal swing rod 273 swings until the swing hook 210 is in the full lock position, and the other end of the full lock signal swing rod 273 abuts against the full lock contact switch 272, the full lock position sensor assembly 270 is triggered, and the controller controls the driving member 230 to stop driving.

[0131] In addition, the half-lock cam edge 213 and the full-lock cam edge 214 are arranged at intervals, so that the half-lock position sensor component 260 and the full-lock position sensor component 270 are triggered at intervals, avoiding triggering the full-lock position sensor component 270 when the swing hook 210 is in the half-lock position, and a smoothly transitioned edge is formed between the half-lock cam edge 213 and the full-lock cam edge 214, which helps to ensure that the sensor component can be triggered smoothly and accurately when the vehicle door transitions from a half-locked state to a fully locked state (or vice versa).

[0132] It should be noted that, in the present embodiment, the half-lock signal push rod 261 and the full-lock signal push rod 271 both extend in the horizontal direction, and the two are spaced apart in the vertical direction. The half-lock signal push rod 261 and the full-lock signal push rod 271 are assembled through a mounting frame, and the mounting frame has two vertical plates spaced apart in the horizontal direction and a connecting plate connecting the two vertical plates. The half-lock signal push rod 261 and the full-lock signal push rod 271 both pass through the two vertical plates, and the parts of the half-lock signal push rod 261 and the full-lock signal push rod 271 located between the two vertical plates are sleeved with a return spring. Taking the half-lock signal push rod 261 as an example, when the half-lock cam edge 213 of the swing hook 210 pushes the half-lock signal push rod 261 to move toward the right side, the return spring is compressed. When the half-lock cam edge 213 of the swing hook 210 disengages from the half-lock signal push rod 261, the half-lock signal push rod 261 is reset under the action of the return spring. The full-lock signal push rod 271 is similar and will not be repeated here.

[0133] Furthermore, in order to more accurately control the movement of the guide rod 241, as Figure 3As shown, in the present embodiment, the door lock device 10 further includes an unlock position sensor assembly 280 electrically connected to the controller, the unlock position sensor assembly 280 includes an unlock signal push rod 281, an unlock contact switch 282, a lock contact switch 283, and an unlock signal swing rod 284 arranged between the unlock signal push rod 281 and the unlock contact switch 282 and the lock contact switch 283, one end of the unlock signal swing rod 284 is slidably connected to the unlock signal push rod 281, and the other end can swing between the unlock contact switch 282 and the lock contact switch 283, and the guide rod 241 is transmission-connected to the unlock signal push rod 281. It should be noted that, in the present embodiment, an outwardly extending extension portion is provided on the upper portion of the guide rod 241, and the extension portion has a guide groove extending in the vertical direction, and the guide groove extends from the upper end to the right to the inflection point, and extends from the inflection point to the left to the lower end, and the left end of the unlocking signal push rod 281 is slidably connected to the guide groove. When the left end of the unlocking signal push rod 281 is located at the inflection point of the guide groove, the lower end of the guide rail is located in the unlocking area 252 of the wheel groove 251, and the other end of the unlocking signal rocker 284 is in contact with the unlocking contact switch 282; when the guide rod 241 moves vertically downward, so that the lower end of the guide rod 241 is located in the attraction area 254 of the wheel groove 251, the left end of the unlocking signal push rod 281 is located at the upper end of the guide groove, and the other end of the unlocking signal rocker 284 is in contact with the locking contact switch 283. It should be noted that, in the process of closing the vehicle door, when the other end of the unlocking signal rocker 284 contacts the locking contact switch 283, the full-lock cam edge 214 also triggers the full-lock position sensor assembly 270. After receiving the full-lock signal fed back by the full-lock position sensor assembly 270 and the locking signal fed back by the unlocking position sensor assembly 280, the controller controls the driving component 230 to stop driving.

[0134] Among them, the connection structure between the unlocking signal rocker rod 284 and the unlocking signal push rod 281 is similar to the connection structure between the half-locking signal push rod 261 and the half-locking signal rocker rod 263 and the connection structure between the full-locking signal push rod 271 and the full-locking signal rocker rod 273, and will not be repeated here.

[0135] In this embodiment, an unlocking position sensor assembly 280 electrically connected to the controller is provided to facilitate detection of the position of the guide rod 241 . The controller can control the drive member 230 to adjust the position of the guide rod 241 based on feedback from the unlocking position sensor assembly 280 .

[0136] Of course, in addition to the above-mentioned method of detecting the positions of the guide rod 241 and the swing hook 210 by the sensor assembly to control the action of the driving member 230, in another alternative embodiment, a Hall motor, a potentiometer, etc. can also be used to accurately control the rotation angle of the motor, thereby realizing the movement of the lower end of the guide rod 241 in various functional areas in the wheel groove 251. Those skilled in the art can design according to actual conditions and specific needs, and this embodiment does not specifically limit this.

[0137] The embodiment of the present invention further provides a car, which includes a body and a door arranged on the body, and also includes any one of the above-mentioned door lock devices 10. The following is a description of the electric door closing in the process of closing the door and the electric door closing in the process of opening the door.

[0138] like Figure 1 As shown, in the door open state, the lock core 100 and the lock tongue 211 on the swing hook 210 are separated, and the limited portion 212 on the swing hook 210 does not cooperate with the half-lock limit portion 221 or the full-lock limit portion 222 on the limit rocker 2201, the half-lock position sensor assembly 260 and the full-lock position sensor assembly 270 are not triggered, the lower end of the guide rod 241 is in the unlocking area 252 of the wheel groove 251, and the unlocking signal rocker 284 touches the unlocking contact switch 282.

[0139] like Figure 4 As shown, in the process of the vehicle door gradually closing from the open state, the lock core 100 abuts against the right side wall of the lock tongue 211, and causes the swing hook 210 to swing in the clockwise direction, and the half-lock cam edge 213 gradually pushes the half-lock signal push rod 261, and links the half-lock signal swing rod 263 to swing in the counterclockwise direction, until the limited portion 212 on the swing hook 210 cooperates with the half-lock limiting portion 221 on the limiting swing rod 2201, and the other end of the half-lock signal swing rod 263 abuts against the half-lock contact switch 262, and the swing hook 210 no longer swings clockwise, but is limited to the half-lock position.

[0140] like Figure 5As shown, when the half-locked position sensor assembly 260 detects that the swing hook 210 is in the half-locked position, the controller controls the rotation motor 231 to move, so that the worm wheel 2501 rotates in the counterclockwise direction, and the lower end of the guide rod 241 moves from the unlocking area 252 of the wheel groove 251 to the suction area 254, and the guide rod 241 moves in the vertical direction. The pressing block 244 in the middle of the guide rod 241 presses on the boss 215 of the swing hook 210, so that the swing hook 210 further swings in the clockwise direction, and the guide rod 2 The unlocking signal push rod 281 at the upper part of 41 moves along the guide groove, and makes the other end of the unlocking signal rocker 284 separate from the unlocking contact switch 282 and swing toward the locking contact switch 283; the limited portion 212 of the swing hook 210 disengages from the half-locked limiting portion 221 and moves toward the fully locked limiting portion 222; the fully locked cam edge 214 on the swing hook 210 pushes the fully locked signal push rod 271, and the other end of the fully locked signal rocker 273 swings toward the fully locked contact switch 272.

[0141] like Figure 6 As shown, when the rotating motor 231 drives the worm gear 2501 to rotate counterclockwise so that the lower end of the guide rod 241 is located in the attraction area 254 of the wheel groove 251, the lock core 100 is completely embedded in the lock tongue 211, and the limited portion 212 of the swing hook 210 cooperates with the full lock limit portion 222 of the limit rocker 2201, the other end of the full lock signal rocker 273 touches the full lock contact switch 272, and the other end of the unlocking signal rocker 284 on the guide rod 241 touches the locking contact switch 283. At this time, the car door is in a closed state.

[0142] Further, if Figure 7 As shown, the rotating motor 231 drives the worm gear 2501 to rotate in the clockwise direction, so that the lower end of the guide rod 241 is located in the unlocking area 252 of the wheel groove 251, and the other end of the unlocking signal rocker 284 on the guide rod 241 touches the unlocking contact switch 282. At this time, the guide rod 241 does not transmit to the swing hook 210 or the limit rocker 2201. On the one hand, it is convenient for the subsequent electric door opening; on the other hand, when the lower end of the guide rod 241 is located in the unlocking area 252 of the wheel groove 251, the handle pusher 290 can press the upper end of the rocker block 245 downward, so that the rocker block 245 pushes the limit rocker 2201 to swing, which is convenient for the user to manually open the door later.

[0143] like Figure 8As shown, during the electric door opening process, the controller receives the door opening command and controls the rotary motor 231 to drive the worm gear 2501 to rotate in the counterclockwise direction, the lower end of the guide rod 241 moves from the unlocking area 252 of the wheel groove 251 to the releasing area 253, and the swing block 245 on the upper part of the guide rod 241 pushes the other end of the limit swing rod 2201, so that the limit swing rod 2201 swings in the counterclockwise direction, and the limited portion 212 of the swing hook 210 is separated from the full locking limit portion 222 of the limit swing rod 2201. At this time, the swing hook 210 swings counterclockwise under the action of the torsion spring, the lock core 100 is separated from the lock tongue 211, and the half-lock position sensor assembly 260 and the full-lock position sensor assembly 270 are changed from the triggered state to the untriggered state, and the door is in the door opening state. . It should be noted that, during the electric door opening process, the lower end of the guide rod 241 may also move from the attraction area 254 of the wheel groove 251 to the release area 253 .

[0144] Further, the rotating motor 231 drives the worm gear 2501 to rotate in the clockwise direction. Figure 1 As shown, the lower end of the guide rod 241 is located in the unlocking area 252 of the wheel groove 251, and the other end of the unlocking signal rocker 284 on the guide rod 241 touches the unlocking contact switch 282. At this time, the guide rod 241 does not transmit to the swing hook 210 or the limit rocker 2201, and the limit rocker 2201 is reset, which is convenient for locking the swing hook 210 in the subsequent door closing process.
