Technical Field

[0001] This application relates to the field of tailgate technology, and in particular to a tailgate lock, a tailgate, and a vehicle. Background Technology

[0002] With the continuous advancement of technology, the automotive industry is undergoing unprecedented changes, and cars are playing an increasingly important role in people's daily lives. As people pay more and more attention to car safety, car manufacturers are also placing greater emphasis on the safety performance of emergency tailgate opening functions.

[0003] Existing tailgate locks are typically mounted on the tailgate sheet metal and equipped with an emergency opening lever, allowing the tailgate to be opened from the inside by manually moving the lever. However, for vehicles with structures such as cameras or license plate light mounting plates at the bottom of the tailgate, the lower part of the tailgate sheet metal usually has mounting holes for these structures. Once the camera or license plate light mounting plate is removed from the outside of the vehicle, a hook can be used to move the lever through the mounting holes at the bottom of the tailgate sheet metal, thus opening the tailgate from the outside and rendering the anti-theft function ineffective. Utility Model Content

[0004] Given that existing tailgate locks can be opened from the outside of the vehicle, thus failing to provide anti-theft functionality, this application provides a tailgate lock, a tailgate, and a vehicle that can ensure the tailgate lock can be opened from inside the vehicle while preventing it from being opened from the outside, thereby improving the vehicle's anti-theft performance.

[0005] According to one aspect of this application, a back door lock is provided, comprising:

[0006] The rear door lock body has a locked state and an unlocked state; and a disc handle, including a handle drive head driven by the rear door lock body and a handle operation disc fixedly connected to the handle drive head; the handle operation disc has an arcuate outer contour arranged around the handle drive head.

[0007] In one embodiment of this application, the handle operation disk further has a plurality of grooves spaced apart on the arc-shaped outer contour and a plurality of anti-slip textures formed on the arc-shaped outer contour, the anti-slip textures being located between two adjacent grooves.

[0008] In one embodiment of this application, the back door lock body includes a lock cylinder and a lock head extending forward from the lock cylinder and linked with the lock cylinder; the handle drive head of the disc handle is inserted into the lock cylinder.

[0009] In one embodiment of this application, the handle operation disk further has at least one pair of avoidance outer contours facing the lock head, the two avoidance outer contours extending gradually from both ends of the arcuate outer contours toward the direction close to the handle drive head.

[0010] In one embodiment of this application, the handle control panel further has a rounded corner profile located at the connection between the avoidance outer contour and the arc-shaped outer contour.

[0011] In one embodiment of this application, the central angle of the arc-shaped outer contour is less than 180°.

[0012] In one embodiment of this application, the back door lock body further includes a reset lever, which is driven to the lock cylinder; one of the clearance outer contours of the handle operation panel faces the lock head, and the other clearance outer contour of the handle operation panel faces the reset lever.

[0013] In one embodiment of this application, the included angle between the two avoidance outer contours is greater than or equal to 45° and less than or equal to 90°.

[0014] According to another aspect of this application, this application further provides a tailgate, comprising:

[0015] A rear door body; and a rear door lock as described in any of the preceding claims, wherein the rear door lock is installed on the rear door body.

[0016] In one embodiment of this application, the tailgate body includes a tailgate frame, a tailgate sheet metal fixedly connected to the tailgate frame, and a tailgate interior panel fixed to the front side of the tailgate sheet metal and having an emergency opening; the tailgate lock body is mounted on the tailgate sheet metal, and the arc-shaped outer contour of the disc handle of the tailgate lock corresponds to the emergency opening of the tailgate interior panel.

[0017] According to another aspect of this application, this application further provides a vehicle, including:

[0018] The vehicle body; and the aforementioned tailgate, which is mounted on the vehicle body.

[0019] In summary, compared to the emergency opening lever of existing tailgate locks, the tailgate lock of this application adopts a handle control panel with an arc-shaped outer contour. This not only ensures that the tailgate can be opened from inside the vehicle, but also ensures that there are no protruding force points on the outer contour of the handle control panel, preventing the handle control panel from being turned by tools such as hooks from outside the vehicle. This ensures that the tailgate cannot be opened from the outside of the vehicle, which helps to improve the anti-theft performance of the vehicle. Attached Figure Description

[0031] The above description of the main component symbols, together with the accompanying drawings and specific embodiments, provides a further detailed explanation of this application. Detailed Implementation

[0032] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0033] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0034] In this application, the term "a" in the specification should be understood as "one or more," that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple. Unless the disclosure of this application explicitly indicates that the number of the element is only one, the term "a" should not be construed as unique or single, and the term "a" should not be construed as a limitation on the quantity.

[0035] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0036] Existing tailgate locks typically feature an emergency opening lever. Once the camera or license plate light mounting plate is removed from the outside of the vehicle, a hook can be used to pry the lever through the mounting holes on the lower part of the tailgate sheet metal, allowing the tailgate to be opened from the outside and thus rendering it ineffective for theft prevention. Therefore, this application creatively proposes a tailgate lock, tailgate, and vehicle that allows the tailgate lock to be opened from the inside of the vehicle while simultaneously preventing it from being opened from the outside, thereby improving the vehicle's anti-theft performance.

[0037] Specifically, refer to the accompanying drawings in the specification of this application. Figures 1 to 4 According to one embodiment of this application, a vehicle is provided, which may include a body and a tailgate 1, the tailgate 1 being mounted on the body for opening or closing the trunk of the body.

[0038] More specifically, such as Figures 2 to 9 As shown, the tailgate 1 may include a tailgate body 10 and a tailgate lock 20 mounted on the tailgate body 10. The tailgate lock 20 includes a tailgate lock body 21 and a disc handle 22; the tailgate lock body 21 has a locked state and an unlocked state; the disc handle 22 includes a handle drive head 221 drivenly connected to the tailgate lock body 21 and a handle operation disc 222 fixedly connected to the handle drive head 221; the handle operation disc 222 has an arcuate outer contour 2221 arranged around the handle drive head 221. Thus, when a user holds the arcuate outer contour 2221 of the handle operation disc 222 and rotates the handle drive head 221 from inside the vehicle, the tailgate lock body 21 can be driven to switch from the locked state to the unlocked state, so as to open the tailgate 1 from inside the vehicle.

[0039] It is worth noting that, compared with the emergency opening lever of the existing tailgate lock, the tailgate lock 20 of this application adopts a handle operation panel 222 with an arc-shaped outer contour 2221. This not only ensures that the tailgate 1 can be opened from inside the vehicle, but also ensures that there are no protruding force points on the outer contour of the handle operation panel 222, preventing the handle operation panel 222 from being turned from outside the vehicle by tools such as hooks. This ensures that the tailgate 1 cannot be opened from outside the vehicle, which helps to improve the anti-theft performance of the vehicle.

[0040] For example, such as Figures 6 to 9 As shown, the handle operation panel 222 also has a plurality of grooves 2222 spaced apart on the arc-shaped outer contour 2221 to support the user's fingers, so as to increase the friction between the fingers and the handle operation panel 222, improve the manual operability of the handle operation panel 222, and ensure that the user can manually open the tailgate 1 from inside the vehicle.

[0041] Preferably, such as Figure 8 As shown, the groove 2222 is implemented as an arc-shaped groove, and the central angle α of the arc-shaped groove is less than 180°, so as to avoid forming a protruding stress point at the groove 2222 while forming a shallow groove for the finger.

[0042] Optionally, such as Figure 8 and Figure 9As shown, the handle operation disk 222 also has a plurality of anti-slip textures 2223 formed on the arc-shaped outer contour 2221. The anti-slip textures 2223 are located between two adjacent grooves 2222 in order to further increase the contour friction of the handle operation disk 222 and improve its manual operation performance.

[0043] It is worth noting that the anti-slip texture 2223 mentioned in this application can be, but is not limited to, a serrated texture. Of course, the anti-slip texture 2223 can also be implemented as other textures such as grooves, grids, or dots, as long as it can achieve the anti-slip effect, which will not be elaborated further in this application.

[0044] According to the above embodiments of this application, as Figures 1 to 5 As shown, the tailgate body 10 of the vehicle tailgate 1 typically includes a tailgate frame 11 rotatably connected to the vehicle body, a tailgate sheet metal 12 fixedly connected to the tailgate frame 11, and a tailgate interior panel 13 fixed to the front side of the tailgate sheet metal 12 and having an emergency opening 130. The tailgate lock body 21 of the tailgate lock 20 is mounted on the tailgate sheet metal 12, and the arcuate outer contour 2221 of the handle operation disc 222 corresponds to the emergency opening 130 of the tailgate interior panel 13, so that the user can hold the arcuate outer contour 2221 of the handle operation disc 222 through the emergency opening 130 to drive the tailgate lock body 21 from the locked state to the unlocked state, thereby opening the vehicle tailgate 1 from inside the vehicle.

[0045] In addition, such as Figure 3 and Figure 5 As shown, the tailgate lock body 21 typically includes a lock cylinder portion 211 disposed between the tailgate sheet metal 12 and the tailgate interior panel 13, and a lock head 212 extending forward from the lock cylinder portion 211 to extend out of the tailgate interior panel 13 and linked with the lock cylinder portion 211; the handle drive head 221 of the disc handle 22 is inserted into the lock cylinder portion 211, and the handle operation disc 222 of the disc handle 22 is located between the lock cylinder portion 211 and the tailgate interior panel 13, so as to ensure that the arc-shaped outer contour 2221 of the handle operation disc 222 is exposed through the emergency opening 130, preventing it from being covered by the tailgate interior panel 13 and affecting the manual opening of the tailgate.

[0046] Optionally, such as Figure 6 and Figure 7As shown, the handle operation panel 222 further has at least one pair of avoidance outer contours 2224 facing the lock head 212. The two avoidance outer contours 2224 extend gradually from both ends of the arcuate outer contour 2221 toward the handle drive head 221, so that the handle operation panel 222 forms a fan-shaped operation panel. In this way, the handle operation panel 222 of this application can avoid the forward-extending lock head 212 or other structural members adjacent to the lock head 212, and at the same time can increase the distance between the arcuate outer contour 2221 and the handle drive head 221, so as to increase the torsional lever arm, which helps to reduce the hand torque required to unlock the tailgate lock body 21 and improve the convenience of opening the tailgate 1 from the inside of the vehicle.

[0047] Optionally, such as Figures 6 to 9 As shown, the handle control panel 222 also has a rounded corner profile 2225 located at the connection between the avoidance outer contour 2224 and the arc-shaped outer contour 2221, so as to avoid forming a protruding force point at the connection between the avoidance outer contour 2224 and the arc-shaped outer contour 2221, ensuring that the handle control panel 222 cannot be driven to rotate from outside the vehicle, thereby improving the vehicle's safety performance.

[0048] Preferably, such as Figure 8 As shown, the central angle β of the arc-shaped outer contour 2221 of the handle operation disc 222 is less than 180°, so as to maximize the distance between the arc-shaped outer contour 2221 and the handle drive head 221, that is, to maximize the torsional arm of the handle operation disc 222, thereby achieving a better force-saving effect. It is understood that in other examples of this application, the central angle β of the arc-shaped outer contour 2221 of the handle operation disc 222 can also be equal to 360°, so that the handle operation disc 222 forms a circular operation disc. Although the radius will be reduced to avoid the lock head 212, resulting in a shorter torsional arm, it can still ensure that the tailgate lock 20 can be opened from inside the vehicle while ensuring that there are no protruding force points on its outer contour, thus preventing the tailgate lock 20 from being opened from outside the vehicle.

[0049] It is worth noting that, such as Figure 3 , Figure 5 , Figure 6 as well as Figure 7 As shown, the back door lock body 21 mentioned in this application may further include a reset lever 213, which is driven to be connected to the lock cylinder 211 and corresponds to the emergency opening 130. It is used to manually move the reset lever 213 through the emergency opening 130 to realize the self-priming reset function of the back door lock body 21.

[0050] Optionally, such as Figure 6 and Figure 7As shown, one of the outer contours 2224 of the handle operation panel 222 faces the lock head 212, and the other outer contour 2224 of the handle operation panel 222 faces the reset lever 213. This is to ensure that the reset lever 213 is exposed through the emergency opening 130 while avoiding the lock head 212 and the reset lever 213, so as to prevent it from being covered by the handle operation panel 222 and affecting the manual opening self-priming reset function.

[0051] Preferably, such as Figure 8 As shown, the included angle θ between the two clearance outer contours 2224 is greater than or equal to 45° and less than or equal to 90°, so as to ensure that the handle operation disc 222 has a sufficiently long arc-shaped outer contour 2221 while avoiding the lock head 212 and the reset lever 213, so that the user can hold the arc-shaped outer contour 2221 to rotate the handle operation disc 222. It is understood that the handle operation disc 222 mentioned in this application can also be designed with rounded corners at the connection between the two clearance outer contours 2224 to avoid forming a protruding stress point.

[0052] Optionally, such as Figure 8 and Figure 9 As shown, the number of grooves 2222 on the arc-shaped outer contour 2221 is four, so that they correspond one-to-one with the user's four fingers, which makes it easier for the user's four fingers to insert into the corresponding grooves 2222 and hold the handle operation panel 222 more securely.

[0053] According to the above embodiments of this application, as Figure 8 As shown, the handle operation panel 222 has a direction indicator 2226 on its surface to indicate the rotation direction of the handle operation panel 222, so that the user can rotate the handle operation panel 222 in the direction indicated by the direction indicator 2226 to drive the rear door lock body 21 from the locked state to the unlocked state. It is understood that the direction indicator 2226 mentioned in this application may be implemented as an arrow, or as a text symbol or sign, which will not be elaborated further in this application.

[0054] It is worth noting that, such as Figure 1 and Figure 2As shown, the tailgate body 10 of the vehicle tailgate 1 may also include an emergency cover 14 detachably mounted on the tailgate interior panel 13 and matching the emergency opening 130. This emergency cover 14 seals the emergency opening 130, preventing foreign objects from contacting the tailgate lock 20 through the emergency opening 130, thus protecting the tailgate lock 20. It also prevents unintentional or accidental contact with the handle operation panel 222 and / or reset lever 213 of the tailgate lock 20 through the emergency opening 130, preventing the tailgate lock 20 from being unintentionally or accidentally opened. It is understood that the emergency cover 14 may be detachably connected to the tailgate interior panel 13 by means of a snap-fit ​​mechanism; furthermore, the emergency cover 14 may have an emergency indicator to remind the user of the emergency opening position of the tailgate lock 20.

[0055] In addition, such as Figure 8 and Figure 9 As shown, the handle operation panel 222 may also have an instrument hole 2227 corresponding to the emergency opening 130, allowing the user to insert an instrument such as a key into the instrument hole 2227 from inside the vehicle, thereby driving the handle operation panel 222 to rotate, achieving a labor-saving effect. It is understood that because the instrument hole 2227 is located on the surface of the handle operation panel 222, and due to the small gaps between the handle operation panel 222 and the emergency cover 14 and the lock cylinder 211, a hook cannot be inserted into the instrument hole 2227 from outside the vehicle, and the rear door lock 20 cannot be opened from the outside.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
