[0001] This utility model relates to the field of vehicle technology, specifically to a door lock device, a door assembly, and a vehicle. Background Technology

[0002] With the continuous development of transportation technology, automobiles have gradually become the main means of transportation. Safety is the part of automobiles that people are most concerned about. In addition to active and passive safety, automobile safety escape devices have also become a focus of attention.

[0003] A search revealed a patent document with authorization announcement number CN218986518U that provides a rear tailgate interior trim panel assembly and a vehicle. In this patent document, a traction mechanism is connected to the emergency switch of the rear tailgate lock. When opening the rear tailgate through the traction mechanism, the cover plate on the rear tailgate trim panel is first removed, and then the cover plate body is pulled. Under the pulling force of the traction mechanism, the emergency switch is triggered.

[0004] However, in existing technologies, the unlocking process is uncertain, which confuses users and reduces the success rate of unlocking. Utility Model Content

[0005] This application provides a door lock device, a door assembly, and a vehicle. It aims to at least resolve user confusion caused by the uncertain unlocking stroke of door lock devices in related technologies.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] According to a first aspect of this application, a door lock device is provided, comprising: a lock body assembly, a rope, and a rope loop, wherein the lock body assembly is disposed on the door of a vehicle, one end of the rope is connected to the lock body assembly, the rope can pull the lock body assembly and unlock the lock body assembly, a portion of the rope can slide through the rope loop, and the rope loop is fixed relative to the door body.

[0008] Based on the aforementioned technical means, the rope loop is relatively fixed to the door body, that is, the position and length of the rope loop are fixed, and thus the length and position of the rope are determined accordingly. When the lock assembly is unlocked by pulling the rope, the rope slides along the extension direction of the rope loop, that is, the rope's stroke is fixed. Therefore, when the lock assembly is unlocked by the rope, the length of the rope pulled out is fixed, so that the user has a clear understanding of the unlocking process, which increases the success rate of unlocking the door lock device and improves the user's escape probability.

[0009] In one possible implementation, the door body includes a first connector with a locking hole, and the outer wall of the rope loop has an annular locking groove, which locks the rope loop to the edge of the locking hole.

[0010] By setting a locking hole on the first connector, the rope loop can be fixed to the door body. The annular groove allows the rope loop to be embedded into the edge of the locking hole, forming a tight and stable connection. During the process of pulling the rope to unlock, the first connector limits the rope loop, allowing the rope to slide inside the lock. After unlocking, when the rope is released, it slides inside the lock in the opposite direction to the unlocking direction, and the first connector again limits the rope loop. This effectively prevents the rope's position from changing due to external forces, allowing the user to quickly locate the rope when using it to unlock, thereby improving stability.

[0011] In one possible implementation, the first connector is further provided with a snap-fit ​​notch, which communicates with the snap-fit ​​hole and extends through the edge of the first connector.

[0012] With the above settings, the rope loop can be installed into the locking hole through the locking notch, or the rope loop can be removed from the locking hole through the locking notch, making it easy to install and remove the rope loop.

[0013] In one possible implementation, the snap-fit ​​notch includes a first notch segment, the width of which is smaller than the diameter of the snap hole.

[0014] With the above settings, the first notch section can limit the rope loop when it is in the locking hole, reducing the chance of the rope loop coming off.

[0015] In one possible implementation, the snap-fit ​​notch includes a second notch segment located on the side of the first notch segment opposite to the snap hole. The second notch segment includes a first end connecting the first notch segment and a second end connecting the edge of the first connector. The width of the second notch segment gradually increases from the first end to the second end.

[0016] With the above configuration, when the rope loop is installed into the snap-fit ​​hole through the snap-fit ​​notch, the second notch section guides the rope loop, making it easier to install the rope loop into the snap-fit ​​hole and increasing convenience.

[0017] In a second aspect, a door assembly is provided, the door assembly including a door body and a door lock device according to any embodiment of the first aspect, wherein the lock body assembly of the door lock device is disposed on the door body.

[0018] In one possible implementation, the inner surface of the door body is provided with a groove, the door lock device is housed in the groove, and the rope of the door lock device is located on the side of the lock body assembly facing away from the bottom surface of the groove.

[0019] With the above settings, the rope can be quickly located via the groove, making it easier for users to find the rope.

[0020] In one possible implementation, the door includes a cover plate that covers an opening for opening or closing the opening.

[0021] With the above settings, the overall aesthetics can be improved when the cover plate covers the opening.

[0022] In one possible implementation, the end of the rope away from the lock body assembly is connected to the rope to form a rope sleeve. The cover plate includes a main body, a hook, and an elastic element. The hook is accommodated in a groove and connected to the main body. A hooking groove is provided between the hook and the main body. The elastic element is provided at the opening of the hooking groove. The rope sleeve is hooked to the hook and is partially accommodated in the hooking groove.

[0023] With the above configuration, the rope loop is attached to the hook, and the user can unlock the lock assembly by removing the cover plate and moving the rope loop. The elastic element can prevent the rope loop from falling off the hook when the cover plate moves the rope loop, which makes the operation convenient for the user.

[0024] Thirdly, a vehicle is provided, the vehicle including a vehicle body and a door assembly according to any possible embodiment of the second aspect above, wherein the door assembly is connected to the vehicle body.

[0025] The beneficial effects of this utility model are:

[0026] (1) The rope has a fixed stroke, so when the lock assembly is unlocked by the rope, the length of the rope pulled out is fixed, so that the user has a clear understanding of the unlocking process, which increases the success rate of unlocking the door lock device and increases the user's escape probability.

[0027] (2) The loop can be embedded into the edge of the loop through the card hole and the annular slot, and the connection is stable.

[0028] (3) The snap-fit ​​notch facilitates the installation and removal of the rope loop from the snap hole.

[0048] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0049] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0050] like Figure 1 As shown, Figure 1 This is a structural schematic diagram of a door assembly 100 provided for one possible embodiment of this application.

[0051] This application provides a door assembly 100, which includes a door body 20 and a door lock device.

[0052] In one possible implementation, the door lock device is located inside the door body 20. The door lock device can be unlocked by electric unlocking or mechanical unlocking.

[0053] Figure 2 This is a schematic diagram of a door lock device provided in one possible embodiment of this application.

[0054] Combination Figure 1 and Figure 2 As shown, this application also provides a door lock device, which includes a lock body assembly 11, a rope 12, and a rope loop 13.

[0055] The lock assembly 11 is located on the door 20 of the vehicle. Specifically, the lock assembly 11 can be located inside the door 20 at a position that facilitates connection with the vehicle body.

[0056] One end of the rope 12 is connected to the lock body assembly 11. The rope 12 can pull the lock body assembly 11 and unlock the lock body assembly 11. Part of the rope 12 can slide through the rope sleeve 13. The rope sleeve 13 is fixed relative to the door body 20.

[0057] The rope loop 13 is fixed relative to the door body 20, that is, the position and length of the rope loop 13 are fixed, and consequently the length and position of the rope 12 are determined. When the lock body assembly 11 is unlocked by pulling the rope 12, the rope 12 slides along the extension direction of the rope loop 13, that is, the stroke of the rope 12 is fixed. Therefore, when the lock body assembly 11 is unlocked by the rope 12, the length pulled out by the rope 12 is fixed, so that the user has a clear understanding of the unlocking process, which increases the success rate of unlocking the door lock device and improves the user's escape probability.

[0058] The embodiments of this application will be described in detail below with reference to the accompanying drawings, and the application scenarios of the embodiments of this application will be introduced first before the detailed description of the embodiments of this application.

[0059] This application provides a vehicle, which includes a vehicle body and a door assembly 100, wherein the door assembly 100 is connected to the vehicle body. Specifically, the vehicle provided in this application can be a sedan, hatchback, commercial vehicle, SUV, MPV, sports car, or other vehicle with doors.

[0060] In one possible implementation, the door assembly 100 is the rear door of the vehicle, and the rear door is a door body 20 facing away from the direction of vehicle travel.

[0061] In one possible implementation, the door assembly 20 can also be another door of the vehicle, such as a side-opening door 20.

[0062] In one possible implementation, the rope loop 13 is connected to the door body 20 by one of welding, bolting, snap-fitting, plugging, locking, magnetic connection, or adhesive.

[0063] Combination Figure 3 , Figure 4 and Figure 5 As shown. In one possible implementation, the door 20 (see...) Figure 1 It includes a first connector 21, which has a locking hole 211. The outer wall of the rope loop 13 has an annular locking groove 131, and the rope loop 13 is locked to the edge of the locking hole 211 by means of the annular locking groove 131.

[0064] By providing a locking hole 211 on the first connector 21, the rope loop 13 can be fixed to the door body 20. The annular groove 131 allows the rope loop 13 to be embedded into the edge of the locking hole 211, forming a tight and stable connection. During the unlocking process by pulling the rope 12, the first connector 21 limits the rope loop 13, allowing the rope 12 to slide within the lock sleeve. After unlocking, when the rope 12 is released, and the rope 12 slides within the lock sleeve in the opposite direction to the unlocking direction, the first connector 21 limits the rope loop 13. This effectively prevents the position of the rope 12 from changing due to external forces, allowing the user to quickly locate the rope 12 when using it to unlock, thereby improving stability.

[0065] In one possible implementation, this example is not shown in the figure. The door body 20 includes a first connector 21 with an annular groove. The outer wall of the rope loop 13 has an annular protrusion, and the rope loop 13 is engaged in the annular groove by means of the annular protrusion.

[0066] By using the above method, the rope loop 13 can be fixed, thereby determining the unlocking stroke, giving users an intuitive understanding of the unlocking process, reducing user confusion, and thus improving the unlocking success rate.

[0067] In one possible implementation, the first connector 21 is further provided with a snap-fit ​​notch 212, which communicates with the snap-fit ​​hole 211 and extends through the edge of the first connector 21.

[0068] With the above settings, the rope loop 13 can be installed in the locking hole 211 through the locking notch 212, or the rope loop 13 can be removed from the locking hole 211 through the locking notch 212, making it easy to install and remove the rope loop 13.

[0069] When maintaining the vehicle, if the rope 12 malfunctions or breaks, maintenance personnel can easily remove the rope 12 and rope loop 13 through the snap-fit ​​notch 212, and then install the rope 12 and rope loop 13 into the snap-fit ​​hole 211 through the snap-fit ​​notch 212, which facilitates maintenance personnel.

[0070] In one possible implementation, the snap-fit ​​notch 212 includes a first notch segment 2121, the width of which is smaller than the diameter of the snap-fit ​​hole 211.

[0071] When the rope loop 13 is located in the locking hole 211, the first notch segment 2121 can limit the rope loop 13, reducing the possibility of the rope loop 13 coming out of the locking hole 211 due to vibration during vehicle operation, thereby improving the stability of the connection between the rope loop 13 and the locking hole 211.

[0072] In one possible implementation, the snap-fit ​​notch 212 includes a second notch segment 2122, which is located on the side of the first notch segment 2121 opposite to the snap hole 211. The second notch segment 2122 includes a first end 2123 connecting the first notch segment 2121 and a second end 2124 connecting the edge of the first connector 21. The width of the second notch segment 2122 gradually increases from the first end 2123 to the second end 2124.

[0073] When the rope loop 13 is installed into the snap-fit ​​hole through the snap-fit ​​notch 212, the rope loop 13 fits into the snap-fit ​​hole 211 from the second end 2124 towards the first end 2123. The second end 2124 of the second notch facilitates the positioning of the rope loop 13. When the rope loop 13 contacts the second notch section 2122, it slides towards the first end 2123 under the guiding effect of the second notch section 2122. The second notch section 2122 guides the rope loop 13, making it easier to install the rope loop 13 into the snap-fit ​​hole and increasing convenience.

[0074] It should be noted that when the rope loop 13 is fitted to the first notch section 2121, the rope loop 13 and the first notch section 2121 can be an interference fit or an elastic fit, and this application does not impose any specific restrictions on this.

[0075] In one possible implementation, the inner surface of the door 20 is provided with a groove 22 (see...). Figure 1 ,and Figure 1 The recess 22 is covered by a cover plate 23. The door lock device is housed in the recess 22, and the rope 12 of the door lock device is located on the side of the lock body assembly 11 facing away from the bottom surface of the recess 22. In this way, the user can quickly locate the rope 12 through the recess 22 when in a state of high tension, thereby unlocking the lock body assembly 11, opening the back door, and facilitating the user's escape.

[0076] It should be noted that the bottom surface of the groove 22 is a closed wall facing the interior space of the vehicle.

[0077] Figure 6 This is a schematic diagram of the structure of the cover plate 23 provided in one possible embodiment of this application. Figure 7 This is a schematic diagram of the structure of the cover plate and the door 20 in one possible embodiment of this application.

[0078] Combination Figure 2 , Figure 6 and Figure 7 As shown, in one possible implementation, the door 20 includes a cover plate 23 that covers the opening 221 for opening or closing the opening 221. When the cover plate 23 covers the opening 221, the overall aesthetics are improved.

[0079] In an emergency, the user only needs to open the cover plate 23 to locate the rope 12, and pull the rope 12 to unlock the lock assembly 11.

[0080] In one possible implementation, the cover plate 23 and the door body 20 are connected by a detachable connection such as snap-fit, elastic connection, plug-in, rotational connection, sliding connection or magnetic connection, and this application does not impose specific limitations on this.

[0081] For example, the cover plate 23 includes an elastic buckle 234 and a limiting member 235. The elastic buckle 234 and the limiting member 235 are respectively disposed on both sides of the cover plate 23. The door body 20 is provided with a limiting part that cooperates with the limiting member 235. The door body 20 is also provided with a recessed part that cooperates with the elastic buckle 234. The cover plate 23 and the door body 20 can be connected by fitting the limiting member 235 into the limiting part and then fitting the elastic buckle 234 into the recessed part.

[0082] In an emergency, the user only needs to pull the elastic buckle 234 to disengage it from the recess, thus removing the cover plate 23. In this way, the cover plate 23 achieves both aesthetic appeal and practicality.

[0083] Specifically, the end of the elastic buckle 234 away from the cover plate 23 is provided with a bent portion 236. The bent portion 236 extends away from the cover plate 23, making it easy to use a finger to press the bent portion 236, thereby causing the elastic buckle 234 to elastically deform and disengage from the recessed portion.

[0084] In one possible implementation, the door body 20 has a recessed area that is recessed away from the interior of the vehicle, and the orthographic projection of the bent portion 236 on the door body 20 is located within the recessed area. This facilitates the user's insertion of their fingers into the bent portion 236, making it easier for the user to operate the elastic buckle 234.

[0085] In one possible implementation, the door 20 includes a door structure and an interior panel. The interior panel is located on the side of the door structure facing the interior space. A lock assembly 11 is positioned between the door structure and the interior panel. An opening is provided on the interior panel, and the end of the rope 12 facing away from the lock assembly 11 is located within the corresponding locking hole 211 area of ​​the opening. This allows the user to quickly locate the rope 12 through the opening even under stressful circumstances, thus enabling them to unlock and escape.

[0086] It should be noted that, in this case, the opening location and lock body assembly 11 (see...) Figure 2 The position of the rope 12 does not need to be set accordingly; it is sufficient to ensure that the rope 12 is located in the opening area.

[0087] The cover plate 23 described above can also cover the locking hole 211 for opening or closing the opening. Further details about the cover plate 23 are omitted here.

[0088] In one possible implementation, the end of the rope 12 facing away from the lock body assembly 11 is connected to the rope 12 and forms a rope loop 121. The rope loop 121 is convenient for the user to grasp by hand and for the user to pull the lock body assembly 11 through the rope loop 121.

[0089] The cover plate 23 includes a main body 231 and a hook 232. The hook 232 is housed in a groove 22 and connected to the main body 231. A hooking groove is provided between the hook 232 and the main body 231. The rope loop 121 is hooked to the hook 232 and is partially housed in the hooking groove.

[0090] Hanging rope 12 on hook 232 can reduce the abnormal noise caused by the collision between rope 12 and vehicle body during the formation process, thereby improving the user experience. At the same time, by hanging rope 12 on hook 232, when the user removes cover 23, cover 23 can pull out rope 12, reducing the time the user spends searching for rope 12 and making it easier for the user to operate.

[0091] Alternatively, the rope loop 121 can be attached to the hook 232. The user can unlock the lock assembly 11 by removing the cover plate 23 and using the rope loop 121. The elastic element 233 can prevent the rope loop 121 from coming off the hook 232 when the cover plate 23 moves the rope loop 121. This design makes it convenient for the user to operate.

[0092] In one possible implementation, the cover plate 23 further includes an elastic element 233, which is disposed at the bending portion 236. When the rope 12 is hooked into the hook groove, the elastic element 233 is squeezed, causing the elastic element 233 to undergo elastic deformation, avoiding the opening 221 of the hook groove, so that the rope 12 is hooked into the hook groove. After the rope 12 is hooked into the hook groove, the elastic element 233 returns to sealing the opening 221 of the hook groove, which can prevent the rope 12 from coming out of the opening 221 of the hook groove and improve the stability of the rope 12 hanging on the hook 232.

[0093] Meanwhile, when removing the rope 12 from the hook 232, the opening 221 of the hook groove can be avoided simply by pressing the elastic element 233, thereby removing the rope 12. This increases convenience and makes it easier for maintenance personnel to perform maintenance.

[0094] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
