Abstract
Description
Technical Field
[0001] This disclosure relates to the field of vehicle technology, and more specifically, to a door assembly and a vehicle. Background Technology
[0002] Currently, most door locks on the market, excluding those for the driver's side, use an external mechanical locking mechanism. This means that the toggle switch or button used for locking is directly exposed outside the door panel. This external mechanical locking mechanism requires a separate mounting point on the door, which increases the complexity of door design and manufacturing, and is also not conducive to optimizing door design space. Utility Model Content
[0003] To overcome the problems existing in the related technologies, this disclosure provides a door assembly and a vehicle.
[0004] According to a first aspect of the present disclosure, a door assembly is provided, comprising:
[0005] Door panel;
[0006] A door lock, including a bolt and an outward unlocking mechanism, wherein the bolt is used to lock or unlock the door, and the outer door handle drives the bolt to unlock the door via the outward unlocking mechanism; and
[0007] The locking mechanism is hidden inside the door panel and can be operated to separate the outward unlocking mechanism from the latch, thereby preventing the door handle from unlocking the door. The door panel is provided with an operating hole for inserting a tool to operate the locking mechanism.
[0008] Optionally, the door lock further includes a locking member having a locking position that separates the outward unlocking mechanism from the bolt. The locking mechanism includes an actuator and a transmission member, wherein the actuator can be operated by an operating tool, and the transmission member is connected to the actuator and the locking member respectively, and can drive the locking member to the locking position under the drive of the actuator.
[0009] Optionally, a slide block is provided on the inner side of the door panel, the actuator includes a slider slidably disposed in the slide block, and the transmission component includes a first pull cable, the first end of the first pull cable being connected to the locking component, and the second end of the first pull cable being connected to the slider.
[0010] Optionally, a sheath is provided at the first end and / or the second end of the first pull cable, and a limiting structure is provided between the sheath and the slide block and / or between the sheath and the door lock, the limiting structure being used to restrict the axial movement of the sheath.
[0011] Optionally, the limiting structure includes an annular groove on the outer circumferential surface of the sheath and a stop portion on the slide and / or the door lock, the stop portion being engaged in the annular groove.
[0012] Optionally, the door lock is provided with an inward unlocking mechanism, through which the inner door handle drives the bolt to unlock the door.
[0013] Optionally, the door lock further includes an unlocking member having an unlocking position that allows the latch to unlock the door. The inward unlocking mechanism includes a second cable, a first end of which is connected to the inward door handle, and a second end of which is connected to the unlocking member. The unlocking member can be driven to a first unlocking position by the inward door handle. In the first unlocking position, the unlocking member drives the locking member to a non-locking position that engages the outward unlocking mechanism with the latch, allowing the outward door handle to unlock the door.
[0014] Optionally, the unlocking member can also be driven to a second unlocking position by the inner door handle, and the unlocking member drives the latch to unlock the door, wherein the travel distance of the unlocking member from the initial position to the second unlocking position is greater than the travel distance of the unlocking member from the initial position to the first unlocking position.
[0015] According to a second aspect of the present disclosure, a vehicle is provided, including a door assembly of any one of the above.
[0016] Optionally, the door assembly is used for the passenger side door and / or the rear doors.
[0017] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: The door assembly provided by this disclosure includes a locking mechanism, wherein the locking mechanism is disposed on the inner side of the door panel and can be operated to separate the outward unlocking mechanism from the latch. The door panel is correspondingly provided with an operating hole for inserting an operating tool to operate the locking mechanism. The door assembly provided by this disclosure hides the locking mechanism on the inner side of the door panel, thereby eliminating the need to reserve installation points on the door for partially exposed structures. This helps reduce the complexity of door design and manufacturing, saves production costs, and because the locking mechanism is disposed on the inner side of the door panel, it does not encroach on the outer space of the door panel, which is beneficial for optimizing the door design space.

Detailed Implementation
[0029] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims. It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are performed in accordance with the relevant data protection laws and policies of the country where the location is situated and with authorization from the owner of the relevant device.
[0030] like Figures 1 to 7 As shown, an exemplary embodiment of this disclosure provides a door assembly. This door assembly can be applied to, but is not limited to, fuel-powered vehicles, pure electric vehicles, or hybrid vehicles; this disclosure does not impose any limitations on this.
[0031] The door assembly disclosed herein includes: a door panel 1, a door lock 2, and a locking mechanism 3. The door panel 1 is installed on the inner side of the door sheet metal, serving as an interior trim component and a mounting carrier for functional components such as buttons and interior door handles. It also provides occupant safety and vibration damping. The door lock 2 includes a latch 23 and an outward unlocking mechanism. The latch is used to lock or unlock the door. The exterior door handle drives the latch 23 to unlock the door via the outward unlocking mechanism. By pulling the exterior door handle from outside the vehicle, the outward unlocking mechanism drives the latch 23 to the unlocked position, facilitating unlocking the door from the outside of the vehicle.
[0032] In some application scenarios, it is necessary to ensure that the car door cannot be opened from the outside after it is locked, thereby protecting the safety of people and property inside the vehicle. This can be achieved through the locking mechanism 3. The locking mechanism 3 can be operated to separate the outward unlocking mechanism from the latch 23, thus preventing the door from being unlocked by the outside door handle. Specifically, when the door is locked, the locking mechanism 3 disengages the mechanical connection between the outward unlocking mechanism and the latch 23. Even if the outside door handle is pulled from the outside, the action cannot be transmitted to the latch 23, and the latch 23 remains engaged with the latch, thereby preventing the door from being unlocked from the outside. It should be noted that the outward unlocking mechanism and the inward unlocking mechanism, which will be introduced later, are both implemented in the prior art and have multiple implementation methods. Their specific structures and working principles will not be described in detail in this disclosure.
[0033] In related technologies, the toggle or button locking mechanism 3 typically has its toggle or button exposed on the door for easy operation. However, the locking mechanism 3 is not frequently used, except in scenarios where the door needs to be locked during a power outage. Exposing the toggle or button requires a separate mounting point on the corresponding location on the door, increasing the complexity of door design and manufacturing, and also taking up some of the door's installation space.
[0034] To address the aforementioned technical issues, the door assembly provided in this disclosure conceals the locking mechanism 3 within the inner side of the door panel 1, specifically within the space between the door panel 1 and the door sheet metal. The corresponding door panel 1 is provided with an operating hole 11 for inserting a mechanical key 8 or a flathead screwdriver, etc., to operate the locking mechanism 3. The door assembly provided in this disclosure conceals the locking mechanism 3 within the inner side of the door panel 1, thus eliminating the need to reserve installation points on the door for partially exposed functional structures. This reduces the complexity of door design and manufacturing, saves production costs, and, because the locking mechanism 3 is located within the inner side of the door panel 1, it does not encroach on the outer space of the door panel 1, thus optimizing the door design space.
[0035] This disclosure does not limit the specific structure of the locking mechanism 3; any structure or method that can be operated to separate the outward unlocking mechanism from the bolt 23 can be applied to this disclosure. In some embodiments, reference may also be made to... Figure 3 and Figure 7 The door lock 2 also includes a locking member 21, which has a locking position that separates the outward unlocking mechanism from the bolt 23. The locking mechanism 3 includes an actuator 31 and a transmission member 32, wherein the actuator 31 can be operated by an operating tool, and the transmission member 32 is connected to the actuator 31 and the locking member 21 respectively, and can drive the locking member 21 to the locking position under the drive of the actuator 31.
[0036] When it is necessary to lock the car door, insert a mechanical key 8 or other operating tool. The operating tool actuates the actuator 31, which drives the transmission component 32. The transmission component 32 then drives the locking component 21, causing the outward unlocking mechanism to separate from the bolt 23. Figure 7 In the illustrated embodiment, the drive transmission component 32 causes the locking component 21 to rotate counterclockwise to the locked position. The locking component 21 drives the linkage structure to disengage the outward opening unlocking mechanism from the latch 23, thereby restricting the unlocking of the door from the outside using the outward opening handle. The mechanical linkage between the actuator 31 and the transmission component 32 helps ensure the stability of the locking mechanism and occupies less space, which is beneficial for optimizing the internal installation space of the door panel 1.
[0037] In some possible implementations, such as Figure 3 and Figure 4As shown, a slide block 4 is provided on the inner side of the door panel 1. The actuator 31 includes a slider 311 slidably disposed within the slide block 4. The transmission component 32 includes a first pull wire 321, the first end of which is connected to the locking component 21, and the second end of which is connected to the slider 311. By using the slide block 4 to guide and constrain the slider 311, the controllability of the sliding path of the actuator 31 can be ensured, and the reliability of the locking component 21's operation can be improved. In addition, the first pull wire 321, as a flexible transmission component, allows for a certain spatial offset between the slider 311 and the locking component 21, reducing the requirements for installation positioning accuracy and adapting to the layout requirements of complex wiring harnesses and functional components inside the door panel 1.
[0038] During the driving process, friction is generated due to relative movement between the first pull cable 321 and the slide block 4, and between the first pull cable 321 and the door lock 2. To avoid wear or even breakage of the first pull cable 321 caused by long-term friction, in some embodiments, such as... Figure 4 and Figure 5 As shown, a sheath 33 is provided at the first end and / or the second end of the first pull cable 321. A limiting structure 5 is provided between the sheath 33 and the slide block 4 and / or between the sheath 33 and the door lock 2. The limiting structure 5 is used to restrict the axial movement of the sheath 33. The sheath 33 covers the outside of the first pull cable 321, thereby protecting at least the positions where the first pull cable 321 rubs against the slide block 4 and the door lock 2, and improving the service life of the first pull cable 321. The limiting structure 5 prevents the sheath 33 from detaching from the slide block 4 and the door lock 2 during the movement of the first pull cable 321, thus losing its protective function.
[0039] As one implementation method for the limiting structure 5, please refer to... Figure 4 and Figure 5 The limiting structure 5 includes an annular groove 331 on the outer circumferential surface of the sheath 33 and a stop portion 41 on the slide block 4 and / or the door lock 2, the stop portion 41 being engaged within the annular groove 331. Specifically, flanges 332 are provided at both ends of the annular groove 331, thereby limiting the sheath 33 when it tends to move with the first pull line 321. Furthermore, the limiting structure 5 also serves as an installation guide, thereby improving the installation efficiency of the sheath 33.
[0040] The following is an example of the locking process of a door assembly provided in this disclosure. Taking the need to lock the door when the electric vehicle is powered off as an example, firstly, open the door that needs to be locked; insert the mechanical key 8 or other operating tools into the inside of the door panel 1 through the operating hole 11; the mechanical key 8 pushes the slider 311 forward, and the slider 311 drives the first pull cable 321 to push the locking member 21, so that the door lock is in a pre-locked state, and the outward unlocking mechanism is separated from the bolt 23; finally, close the door, and the door lock 2 is now in a locked state, and people outside the vehicle cannot open the door.
[0041] In some implementations, such as Figure 6 As shown, the door lock 2 is also equipped with an inward unlocking mechanism. The inward door handle 6 drives the bolt 23 to unlock the door through the inward unlocking mechanism. Specifically, when the door is locked, pulling the inward door handle drives the inward unlocking mechanism on the door lock 2, which in turn drives the bolt 23 to unlock the door.
[0042] The door lock 2 may also include an unlocking element 22, which has an unlocking position that allows the latch 23 to unlock the door. The inward unlocking mechanism includes a second pull cable 7, the first end of which is connected to the inner door handle 6, and the second end of which is connected to the unlocking element 22. Under the drive of the inner door handle 6, the unlocking element 22 can be driven to a first unlocking position. In the first unlocking position, the unlocking element 22 drives the locking element 21 to a non-locking position that engages the outward unlocking mechanism with the latch 23, allowing the outer door handle to unlock the door.
[0043] In some implementations, such as Figure 7 As shown, a linkage mechanism can be provided between the unlocking component 22 and the locking tongue 23. The linkage mechanism may include, for example, a linkage component 24 and a pusher component 25. The second pull cable 7 drives the unlocking component 22, which in turn drives the linkage component 24. The linkage component 24 drives the pusher component 25 to move, and the pusher component 25 pushes the locking tongue 23 to the first unlocking position.
[0044] In other embodiments, the unlocking member 22 can also be driven to a second unlocking position by the inner door handle 6, and the unlocking member 22 drives the latch 23 to unlock the door. The travel distance of the unlocking member 22 from its initial position to the second unlocking position is greater than the travel distance of the unlocking member 22 from its initial position to the first unlocking position. This allows the door to be unlocked from the outside when the inner door handle 6 is pulled, and then unlocked from the inside when the inner door handle 6 is pulled again.
[0045] The following is an example of an unlocking process for a door assembly provided in this disclosure. Figure 7As shown, the occupant enters the vehicle from the driver's side; by pulling the inner door handle 6 on the side to be unlocked once, the second cable 7 moves the unlocking component 22 to the first unlocking position. The unlocking component 22 drives the locking component 21 to the unlocked position (the locking component 21 moves clockwise in the opposite direction to the locking direction), putting the door lock 2 in the outward unlocking state. The outward unlocking mechanism engages with the latch 23, and the door can be unlocked using the outward door handle. Pulling the inner door handle 6 again moves the second cable 7 to the second unlocking position, and the inward unlocking mechanism pushes the latch 23, allowing the door to be unlocked using the inward door handle. Thus, different mechanical door unlocking methods can be achieved even when the vehicle is powered off, suitable for different door unlocking scenarios.
[0046] According to a second aspect of the present disclosure, a vehicle is also provided, including any of the door assemblies described above, and having all of their beneficial effects, which will not be repeated here. In some embodiments, the door assembly can be used for the passenger side door and / or the rear door, or in other words, it can be used for any door except the driver's side door. The driver's side door is locked or unlocked using a lock cylinder, and the other doors are locked or unlocked using lock cylinders.
[0047] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.
[0048] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
[0049] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
