Description

Technical Field

[0001] This application belongs to the field of vehicle technology, specifically relating to a door unlocking / closing device and a vehicle. Background Technology

[0002] Electronic door locks are widely used in new energy vehicles. Compared with traditional mechanical door locks, electronic door locks are favored for their convenience and efficiency, allowing control of all door locks with just a touch of a button. However, when the remote control device of the electronic door lock is out of power, the electronic door lock control has no signal, or the vehicle's electrical system fails, the electronic door lock, which relies on electric drive and signal control, may not function properly, preventing passengers inside the vehicle and people outside from opening or locking the doors in a timely manner. Summary of the Invention

[0003] The purpose of this application is to provide a door unlocking and locking device and a vehicle that can meet the needs of emergency door unlocking and locking.

[0004] To achieve the above objectives, this application provides a door unlocking / locking device, which includes:

[0005] A control arm, used for connecting to the lock arm of a door lock and equipped with a movable connecting part; and

[0006] The locking / unlocking mechanism has a drive input end and a drive output end that are connected by a transmission. The drive input end can move to an unlocked position, a reset position, or a locked position. The drive output end is movably connected to the movable connecting part and can drive the control arm to move between a first position and a second position. The position of the first end of the movable connecting part, which is relatively closer to the first position, when the control arm is in the second position is the same as the position of the second end of the movable connecting part, which is relatively farther from the first position, when the control arm is in the first position.

[0007] When the drive input terminal is in the unlocked position, the control arm is in the first position and the drive output terminal is in the first end of the movable connection portion, and the lock arm unlocks the door lock;

[0008] When the drive input terminal is in the reset position, the control arm is in the first position and the drive output terminal is in the second end of the movable connection portion; or, the control arm is in the second position and the drive output terminal is in the first end of the movable connection portion.

[0009] When the drive input terminal is in the locked position, the control arm is in the second position and the drive output terminal is at the second end of the movable connection portion, and the locking arm locks the door lock.

[0010] In some specific embodiments, the movable connection portion may be formed as a slide groove disposed on the control arm, and the drive output end may be movably disposed in the slide groove along the extension direction of the slide groove.

[0011] In some specific embodiments, the control arm may include:

[0012] Control unit, the slide is disposed on the control unit; and

[0013] The mounting part is detachably connected to the locking arm.

[0014] In some specific embodiments, the slide groove may be formed on the side wall of the control unit, and the control unit is further provided with a limiting slide cavity that extends in the same direction as the slide groove and communicates with the slide groove. The drive output end includes an intermediate transmission part and a slider part. The intermediate transmission part extends into the limiting slide cavity from the side opening of the limiting slide cavity along the extension direction of the slide groove, and the slider part extends into the slide groove from the limiting slide cavity.

[0015] In some specific embodiments, the locking arm switches the working state of the door lock by rotating and swinging, and the cavity wall of the limiting slide cavity away from the mounting part may be provided with an avoidance opening that communicates with the side opening.

[0016] In some specific embodiments, the cavity wall of the limiting slide cavity opposite to the clearance opening is provided with an elastic opening that communicates with the side opening and extends along the extension direction of the slide groove.

[0017] In some specific embodiments, the mounting part may include a slot that can engage with the locking arm, and the two ends of the slot are respectively provided with hooks.

[0018] In some specific embodiments, the mounting portion may include a first connecting plate and a second connecting plate extending outward from the control portion and arranged at intervals, with the slot defined between the first connecting plate and the second connecting plate.

[0019] In some specific embodiments, the extension length of the first connecting plate is greater than the extension length of the second connecting plate, the protruding end of the first connecting plate is provided with the hook facing the second connecting plate, and the protruding end of the second connecting plate is provided with the hook facing the first connecting plate.

[0020] In some specific embodiments, the locking / unlocking mechanism may include a lock cylinder assembly and an intermediate transmission assembly. The lock cylinder assembly has its cylinder forming the drive input end and is capable of switching positions by rotation and oscillation. One end of the intermediate transmission assembly is connected to the lock cylinder, and the other end forms the drive output end.

[0021] The lock cylinder assembly may further include a reset member, the reset member being used to drive the lock cylinder to rotate and reset to the reset position; and / or

[0022] The lock cylinder assembly also includes a mechanical key, which can engage with the lock cylinder and drive the lock cylinder to rotate and swing; and / or

[0023] The intermediate transmission assembly includes a cable and a cable sleeve. The cable passes through the cable sleeve, with one end of the cable connected to the lock cylinder and the other end forming the drive output end.

[0024] A second aspect of this application also provides a vehicle comprising:

[0025] Car door locks; and

[0026] In the aforementioned door unlocking and locking device, the control arm is connected to the locking arm of the door lock.

[0027] In some specific embodiments, the vehicle may further include a sliding door, and the door unlocking device is disposed on the sliding door; and / or,

[0028] The vehicle door includes an outer mounting groove and an exterior door handle, the exterior door handle being pivotally mounted in the mounting groove, and the lock cylinder key socket of the unlocking mechanism being located in the mounting groove and exposed when the exterior door handle is pivotally pulled open.

[0029] Through the above technical solution, the drive input end of the unlocking and locking mechanism can drive the door lock arm to move by switching to the unlocked or locked position, so that the door lock can switch to the unlocked or locked state accordingly, thereby meeting the vehicle's emergency unlocking and locking requirements. Furthermore, since the drive input end of the unlocking and locking mechanism has a reset position, and the drive output end is movably connected to the movable connecting part, when the drive input end switches to the reset position, it can drive the drive output end to reset to the intermediate initial position. This ensures that the drive output end will not interfere with the control arm and lock arm when they operate independently, thus allowing the unlocking and locking mechanism and other drive structures of the lock arm to operate independently without interference, meeting the vehicle's unlocking and locking requirements under all operating conditions.

[0048] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0049] This application provides a vehicle door unlocking and locking device. For ease of understanding, before introducing the vehicle door unlocking and locking device of this application, existing vehicle door locks will be introduced first. The vehicle door lock targeted in this application is an electronic door lock. Due to the convenience and efficiency of electronic door locks, most existing new energy vehicle door locks are electronic door locks. Electronic door locks use electric power to drive the lock arm 3 to switch control positions, thereby realizing the electric control of unlocking and locking of the vehicle door.

[0050] In the daily use of new energy vehicles, if the door lock only has a single power control structure to drive the door lock to unlock and lock, when special situations such as the remote control device having no power, no signal, or the vehicle having no power occur, passengers inside the vehicle and people outside the vehicle will not be able to open or close the door in time, which is extremely inconvenient and poses certain safety hazards.

[0051] The locking arm 3 of the electronic door lock can be a swing arm structure or a linear displacement structure. The door lock can be unlocked or locked by switching the control position of the locking arm 3. For example, when the locking arm 3 is a swing arm structure, the locking arm 3 can be rotated to one side to unlock the door lock, and rotated to the other side to lock the door lock.

[0052] like Figure 1 and Figure 2 As shown, this application provides a novel vehicle door unlocking and locking device, which includes a control arm 1 and an unlocking and locking mechanism 2. The control arm 1 is connected to the locking arm 3 of the vehicle door lock and can drive the locking arm 3 to switch control positions, thereby realizing the electric control of unlocking and locking of the vehicle door. The control arm 1 is provided with a movable connecting part, and the unlocking and locking mechanism 2 has a drive input end and a drive output end that are connected by transmission. The drive input end can move to an unlock position, a reset position, or a locked position, that is, the drive input end can switch positions between the unlock position and the reset position, and between the reset position and the locked position. The drive output end is movably connected to the movable connecting part and can drive the control arm 1 to move between a first position and a second position, thereby indirectly driving the locking arm 3 to move. The drive output end is movably connected to the movable connecting part, that is, the drive output end can move between the first end and the second end of the movable connecting part. The position of the first end of the movable connection that is relatively close to the first position when the control arm 1 is in the second position is the same as the position of the second end of the movable connection that is relatively far from the first position when the control arm 1 is in the first position. In this way, the drive output end can move to this position regardless of whether the control arm 1 is in the first position or the second position, and this position is the middle initial position of the drive output end.

[0053] Among them, such as Figure 3 and Figure 4 As shown, when the drive input is in the unlocked position, the control arm 1 is in the first position and the drive output is at the first end of the movable connection. The lock arm 3 unlocks the door lock. That is, when the drive input is switched to the unlocked position, the drive input can drive the drive output to act on the movable connection to move the control arm 1 to the first position, so that the door lock switches to the unlocked state. When the drive input is in the reset position, the control arm 1 is in the first position and the drive output is at the second end of the movable connection, or the control arm 1 is in the second position and the drive output is at the first end of the movable connection. That is, when the drive input is switched to the reset position, the drive input can drive the drive output to move relative to the movable connection so that the drive output is reset to the intermediate initial position. The interaction force between the drive output and the movable connection in the intermediate initial position is zero. When the drive input is in the locked position, the control arm 1 is in the second position and the drive output is at the second end of the movable connection. The locking arm 3 locks the door lock. That is, when the drive input is switched to the locked position, the drive input can drive the drive output to act on the movable connection to move the control arm 1 to the second position so that the door lock is switched to the locked state.

[0054] Specifically, when the car door lock is in the locked state, if an emergency unlocking of the car door lock is required, such as... Figure 1 and Figure 3 As shown, the drive input can be switched from the reset position to the unlock position. In this position, the drive input drives the drive output to act on the first end of the movable connection, causing the control arm 1 and locking arm 3 to swing towards the first position, thus unlocking the door lock. After the door lock is unlocked in an emergency, the drive input switches from the unlock position to the reset position. In this position, the drive input drives the drive output to move relative to the movable connection towards the second end, resetting the drive output to its initial intermediate position. Because the drive output and the movable connection are in a movable connection that allows relative movement, the control arm 1 and locking arm 3 remain in the unlocked position of the door lock. Therefore, when the door lock is subsequently locked by other drive mechanisms, and the control arm 1 and locking arm 3 move towards the locking side of the movable connection, there will be no interference with the drive output due to the movable connection that allows relative movement.

[0055] Similarly, when the car door locks are in the unlocked state, if an emergency locking of the car door locks is required, such as... Figure 1 and Figure 4As shown, when the drive input is switched from the reset position to the locked position, the drive input can drive the drive output to act on the second end of the movable connection, causing the control arm 1 and the locking arm 3 to swing towards the second position, thereby switching the door lock to the locked state. After the door lock is locked in an emergency, the drive input is switched from the locked position to the reset position. At this time, the drive input can drive the drive output to move relative to the movable connection towards the first end, and the drive output returns to the initial intermediate position. Since the drive output and the movable connection are in a movable connection that allows relative movement, the control arm 1 and the locking arm 3 remain in the locked state of the door lock. Thus, when the door lock is subsequently unlocked by other drive mechanisms, when the control arm 1 and the locking arm 3 move towards the unlocking side of the movable connection, there will be no interference with the drive output due to the movable connection that allows relative movement.

[0056] As can be seen, after the drive output end is reset to the initial position, since the drive output end and the movable connection part are in a movable connection relationship that can move relative to each other, when the door lock is locked or unlocked by other drive methods, the drive output end and the control arm will not affect each other. That is, the locking and unlocking mechanism and the other drive structures of the lock arm 3 can operate independently without interfering with each other, which can meet the locking and unlocking requirements of the vehicle under all working conditions.

[0057] The structure in which the drive output end and the movable connecting part are movably connected can take various forms, such as a sliding block or a sliding rail. Based on the different structural forms of the locking arm 3, the structural forms of the control arm 1 and the locking / unlocking mechanism 2 can also be adaptively designed. For example, the control arm 1 and the locking arm 3 can be independently set components, detachably or fixedly connected; or, the control arm 1 and the locking arm 3 can be formed as a single integral part. Furthermore, the locking / unlocking mechanism 2 can realize manual mechanical emergency unlocking and locking operations of the door lock through a lock cylinder assembly or a lock cylinder assembly combined with an intermediate transmission assembly, and the intermediate transmission assembly can be a cable mechanism or a linkage mechanism. Moreover, the drive input end of the locking / unlocking mechanism 2 can be manually reset or driven reset by a reset component.

[0058] In some specific embodiments, the control arm 1 and the locking arm 3 can be independently set components. In this way, the unlocking and locking mechanism 2 can indirectly drive the locking arm 3 by setting the control arm 1 separately and connecting it to the locking arm 3. This can be done in parallel with the original door lock unlocking and locking structure without changing the original door lock unlocking and locking structure, making the structure of the door unlocking and locking device more reasonable and simple, and also greatly reducing the design and manufacturing cost of the vehicle.

[0059] In some specific implementations, such as Figure 1 and Figure 2As shown, the movable connection part can be formed as a slide groove 111 provided on the control arm 1, and the drive output end is movably provided in the slide groove 111 along the extending direction of the slide groove 111. In this way, the drive output end and the slide groove 111 can form a movable connection that can move relative to each other, and the structure of the control arm 1 is simpler and more compact.

[0060] In some specific implementations, such as Figure 1 and Figure 2 As shown, the control arm 1 may include a control part 11 and a mounting part 12. A slide groove 111 is provided on the control part 11, and the mounting part 12 is detachably connected to the lock arm 3. In this way, the original structure of the lock arm 3 of the door lock can be changed without altering it, which also simplifies the installation of the control arm 1 and further reduces the design and manufacturing cost of the vehicle.

[0061] In some specific implementations, such as Figure 1 and Figure 2 As shown, the slide groove 111 can be formed on the side wall of the control unit 11. The control unit 11 can also be provided with a limiting slide cavity that extends in the same direction as the slide groove 111 and communicates with the slide groove 111. The drive output end includes an intermediate transmission part 21 and a slider part 22. The intermediate transmission part 21 extends into the limiting slide cavity from the side opening of the limiting slide cavity along the extension direction of the slide groove 111, and the slider part 22 extends into the slide groove 111 from the limiting slide cavity. In this way, the cavity wall of the limiting slide cavity can support and limit the intermediate transmission part 21, making the movable connection structure between the drive output end and the movable connection part simpler, more compact, and more stable and reliable.

[0062] Specifically, such as Figure 1 and Figure 2 As shown, the intermediate transmission part 21 and the slider part 22 are connected to each other and formed into an L-shape. The slider part 22 is located in the slide groove 111. When the drive input end is switched to the locked position or the unlocked position, the slider part 22 drives the control arm 1 to move by acting on the end wall of the slide groove 111.

[0063] In some specific implementations, such as Figure 1 and Figure 2 As shown, the locking arm 3 is a swing arm structure, which can switch the working state of the door lock by rotating and swinging. In order to avoid interference between the locking arm 3 and the drive output end when swinging, the cavity wall of the limiting slide cavity away from the mounting part 12 can be provided with a clearance opening 112 that communicates with the side opening. In this way, when the locking arm 3 swings, the intermediate transmission part 21 can pivot outward through the clearance opening 112.

[0064] Optionally, such as Figure 2As shown, the cavity wall of the limiting slide cavity opposite to the clearance opening 112 is provided with an elastic opening that communicates with the side opening and extends along the extension direction of the slide groove 111. The clearance opening 112, the limiting slide cavity, and the elastic opening are sequentially connected to form a through groove that penetrates the two opposite cavity walls of the limiting slide cavity. In this way, when the intermediate transmission part 21 and the slider part 22 extend into the limiting slide cavity from the side opening, the two opposite cavity walls of the limiting slide cavity can undergo elastic deformation to facilitate the extension of the intermediate transmission part 21 and the slider part 22 into the limiting slide cavity, making the overall structure more reasonable and the installation operation more convenient.

[0065] In some specific embodiments, the mounting part 12 may include a slot capable of engaging with the locking arm 3, with hooks 121 at both ends of the slot. For example... Figure 1 As shown, the locking arm 3 has multiple weight-reducing hollow slots and crossbeams at both ends of the multiple weight-reducing hollow slots. The slot of the mounting part 12 can be fastened to the crossbeams and the hook 121 is hooked to the crossbeams by passing through the weight-reducing hollow slots, thereby realizing the detachable connection between the control arm 1 and the locking arm 3. The structure is simple and reliable.

[0066] In some specific implementations, such as Figure 2 As shown, the mounting portion 12 may include a first connecting plate 122 and a second connecting plate 123 extending outward from the control portion 11 and arranged at intervals, with a slot defined between the first connecting plate 122 and the second connecting plate 123. This makes the structure of the control arm 1 simpler and lighter, and reduces manufacturing costs. The surfaces of the first connecting plate 122 and the second connecting plate 123 are parallel to the extending direction of the slide groove 111 and extend downward from the two sides of the elastic opening.

[0067] Optionally, such as Figure 2 As shown, the protruding end of the first connecting plate 122 is provided with a hook 121 facing the second connecting plate 123, and the protruding end of the second connecting plate 123 is provided with a hook 121 facing the first connecting plate 122. Thus, the two hooks 121 can act on the locking arm 3 from two opposite directions. The control unit 11 is connected to the mounting unit 12 and formed into an approximately L-shape, with the control unit 11 located above the mounting unit 12. The first connecting plate 122 extends downward from one side of the limiting slide cavity wall, and the second connecting plate 123 extends downward from the other side of the limiting slide cavity wall. The extension lengths of the first connecting plate 122 and the second connecting plate 123 are different, forming an asymmetrical structure with one long and one short. This allows the two hooks 121 to be staggered, and thus hooked onto different crossbeam portions. Since the locking arm 3 is a thin-walled component, the staggered arrangement of the two hooks 121 avoids interference between them.

[0068] In some specific embodiments, the control unit 11 has a limiting groove on its side wall relatively close to the mounting part 12, which is adapted to the outer contour of the locking arm 3. The limiting groove is located between the first connecting plate 122 and the second connecting plate 123. When the mounting part 12 is fastened to the locking arm 3, the limiting groove matches and positions the locking arm 3, so that a multi-directional limiting connection can be formed between the control arm 1 and the locking arm 3, making the structure more stable and reliable.

[0069] In some specific embodiments, the locking / unlocking mechanism 2 may include a lock cylinder assembly 23 and an intermediate transmission assembly. The lock cylinder of the lock cylinder assembly is configured as a drive input end and can be rotated and oscillated to switch positions. One end of the intermediate transmission assembly is connected to the lock cylinder, and the other end is configured as a drive output end. Figure 1 As shown, the lock cylinder assembly 23 is a manually driven mechanical lock cylinder. The lock cylinder assembly 23 also includes a mechanical key 231 and a lock cylinder key socket 232. The mechanical key 231 can cooperate with the lock cylinder key socket 232 and drive the lock cylinder to rotate and swing.

[0070] In some specific embodiments, the lock cylinder assembly 23 may further include a reset member (not shown in the figure), which is used to drive the lock cylinder to rotate and reset to the reset position. The reset member can be provided in various forms. For example, the reset member can be a torsion spring provided on the rotation shaft of the lock cylinder, or it can be a reset spring provided to stop the rotation of the outer end of the lock cylinder.

[0071] In some specific implementations, such as Figure 1 As shown, the intermediate transmission assembly may include a cable 24 and a cable sleeve 25. The cable 24 is inserted into the cable sleeve 25. One end of the cable 24 is connected to the lock cylinder, and the other end forms a drive output end.

[0072] In some specific embodiments, the locking / unlocking mechanism may further include a mounting bracket 26, which is used to install and fix the intermediate transmission assembly. For example... Figure 1 As shown, the mounting bracket 26 is disposed on the cable sleeve 25 to securely mount the cable sleeve 25. Alternatively, in some other embodiments, the intermediate transmission assembly may include a linkage assembly, one end of which is connected to the lock cylinder, and the other end which forms a drive output end.

[0073] Specifically, the following will be based on Figure 1 Taking the door unlocking and locking device as an example, the movement process of the door unlocking and locking device will be briefly explained. Figure 1 As shown, the mechanical key 231 is inserted into the key slot 232 of the lock cylinder and rotated clockwise and counterclockwise, causing the lock cylinder to switch to the unlocked or locked position. One end of the pull cable 24 is connected to the lock cylinder, and the lock cylinder drives the pull cable 24 to move. The other end of the pull cable 24 is connected to the control arm 1 and drives the control arm 1 to move, which in turn drives the lock arm 3 to rotate, thereby realizing the unlocking and locking of the door lock. Figure 1 and Figure 3 As shown, when the locking arm 3 is in the locked position and the door lock is operated normally via electric control, the locking arm 3 is driven to rotate by the motor, moving directly from the locked position to the unlocked position. At this time, the slide 111 moves, and the cable 24 remains stationary. However, when the locking arm 3 is in the locked position and the door lock is operated manually via emergency control, the mechanical key 231 is first rotated clockwise. At this time, the end of the cable 24 drives the control arm 1 to move. After the control arm 1 moves to the unlocked position, the cable 24 returns to its original position by the lock cylinder torsion spring. Figure 1 and Figure 4 As shown, when the locking arm 3 is in the unlocked position and the door lock is operated by the normal electric control, the locking arm 3 is driven to rotate by the motor and moves directly from the unlocked position to the locked position. At this time, the slide 111 moves and the cable 24 does not move. When the locking arm 3 is in the unlocked position and the door lock is operated by the emergency manual control, the mechanical key 231 is first rotated counterclockwise. At this time, the end of the cable 24 drives the control arm 1 to move. After the control arm 1 moves to the locked position, the cable 24 is reset by the lock cylinder torsion spring.

[0074] A second aspect of this application also provides a vehicle including a door lock and the aforementioned door unlocking / locking device, with a control arm 1 connected to the locking arm 3 of the door lock. Since the vehicle includes the aforementioned door unlocking / locking device, it also possesses all the technical effects brought about by the door unlocking / locking device, and therefore will not be repeated.

[0075] With the development of the automotive industry, electrification and intelligentization have become mainstream trends. Consumers have increasingly higher requirements for the quality of automotive details. The widespread use of features such as hidden exterior door handles, smart keys, card keys, and unlocking via mobile phones or wearable devices has made the user experience increasingly convenient. However, the requirements for the placement of emergency unlocking devices under special conditions are also becoming increasingly stringent. These devices must not only be invisible or inconspicuous in daily use, but also be quickly located and easily operated in emergency situations. Most conventional models place the emergency unlocking device on the driver's side door. However, with the widespread use of hidden exterior door handles, coupled with the increasing number of integrated functions on the doors (electric door opening and closing systems, high-power mid-range and low-range speakers, flush-mounted power windows, larger door panel storage space, and more control buttons on the door panels), placing the emergency unlocking device on the driver's side door is becoming increasingly difficult.

[0076] To further meet users' needs for spaciousness, comfort, and convenience in vehicles, in some specific implementations, the vehicle also includes a sliding door, and the door unlocking and locking device can be installed on the sliding door.

[0077] In some specific embodiments, the vehicle door may include an outer mounting recess 41 and an exterior door handle 42, the exterior door handle 42 being pivotally mounted in the mounting recess 41, and the key slot 232 of the locking / unlocking mechanism 2 being located in the mounting recess 41 and exposed when the exterior door handle 42 is pivotally pulled open. Specifically, as Figure 5 As shown, when in use, press one end of the door handle 42, and the other end of the door handle 42 will lift up and expose the lock cylinder operating space. Insert the matching mechanical key 231 into the lock cylinder key slot 232 and rotate it, which will drive the cooperating cable 24 to move. Rotate clockwise to pull and push counterclockwise.

[0078] It should be noted that the structure and principle of components such as the lock cylinder assembly 23 and the electronic door lock with the lock arm 3 are well known to those skilled in the art and are not part of the core improvement of this application, so they will not be described in detail here.

[0079] In summary, this application provides a door unlocking and locking device and a vehicle, which can connect an emergency external unlocking mechanism in parallel without changing the original centrally controlled electric unlocking and locking structure of the door. This allows the two structures to operate independently and serve as backups for each other. The unlocking and locking mechanism 2 adopts a pull-wire sliding groove structure, ensuring that the electronic drive structure and the emergency manual drive structure do not interfere with each other during operation. This allows daily electronic control and emergency manual operation to complement each other, meeting the unlocking and locking requirements under all working conditions. In addition, the pull-wire sliding groove structure of the unlocking and locking mechanism 2 can be applied to vehicles with sliding doors, solving the problem of difficult driver's door placement. It enables the sliding door to be mechanically unlocked and locked from the outside of the vehicle, meeting the needs of emergency unlocking and locking in special circumstances (such as when the remote control device has no power, no signal, or the vehicle has no power), thus improving the convenience for consumers.

[0080] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
