[0045] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0046] The following is a reference appendix. Figures 1 to 9 This invention describes a door lock system, a door assembly, and a vehicle according to embodiments of the present invention.

[0047] like Figures 1 to 5 As shown, the door lock system of this utility model embodiment includes: an outer door handle 1, a door lock 2, and a linkage component 3. The outer door handle 1 can rotate around a first axis, which extends in the vertical direction. The linkage component 3 includes a connector 31 and a pull rod 32. The connector 31 is connected to the door lock 2 and can rotate around a second axis to drive the door lock 2 to move between an open position and a closed position. The outer door handle 1 is connected to the connector 31 through the pull rod 32, and the outer door handle 1 can drive the pull rod 32 to move, thereby driving the connector 31 to rotate.

[0048] According to the door lock system of the embodiment of this utility model, the user can operate the outer door handle 1 and rotate it around the first axis. Under the linkage of the pull rod 32, the adapter 31 can rotate synchronously to switch the door lock 2 between the open and closed positions. The door lock system of the embodiment of this utility model can complete the opening and closing of the door lock 2 through the transmission of the pull rod 32 and the adapter 31. This makes the structural design of the door lock system simple, the transmission stroke short, and is conducive to arranging the door lock system inside the car door 5, resulting in better performance.

[0049] It is understandable that the vertical and horizontal directions of the door lock system are consistent with the vertical and horizontal directions of the door 5.

[0050] like Figure 1 and Figure 4 As shown, the outer door handle 1 is installed on the outer door panel 51 of the car door 5. When the user pulls the outer door handle 1 outward, the outer door handle 1 can rotate horizontally around the first axis. At this time, the outer door handle 1 can directly drive the lever 32 to move, so as to drive the adapter 31 to rotate around the second axis. With the cooperation of the lever 32 and the adapter 31, the door lock 2 can be opened to unlock the car door 5.

[0051] Optionally, such as Figure 4 As shown, the pull rod 32 extends along the inward and outward directions of the door 5. It can be understood that the inward and outward directions of the door 5 correspond to the thickness direction of the door 5. Since the pull rod 32 extends along the thickness direction of the door 5, when the door lock system is matched with door 5s of different thicknesses, the length of the pull rod 32 can be adjusted according to actual needs so that the door lock system can match door 5s of different thicknesses. This improves the flexibility of the door lock system during use and has a wider range of applications.

[0052] like Figure 5 and Figure 6 As shown, one end of the pull rod 32 (such as...) Figure 6 The outer end of the middle pull rod 32 is pivotally connected to the outer door handle 1, and the other end of the pull rod 32 (such as...) Figure 6 The inner end of the pull rod 32 is pivotally connected to the adapter 31. In other words, the outer door handle 1, the pull rod 32, and the adapter 31 can form a multi-link structure, meaning the outer door handle 1 can rotate relative to the pull rod 32, and the pull rod 32 can also rotate relative to the adapter 31. This reduces the range of motion of the linkage component 3, results in a compact structure, minimizes the space occupied by the linkage component 3, and makes the force transmission process of the pull rod 32 smoother.

[0053] like Figure 4 and Figure 5 As shown, when the user pulls the outer door handle 1 outward, under the action of leverage, the outer door handle 1 can drive the push rod 32 to move towards the inside of the door 5. Because the other end of the push rod 32 (such as...) Figure 6 The inner end of the pull rod 32 is pivotally connected to the adapter 31, so that the other end of the pull rod 32 can push the adapter 31 to rotate about the second axis to open the door lock 2.

[0054] Optionally, such as Figure 8As shown, the outer door handle 1 includes a handle body 11 and a transition bracket 12. The handle body 11 and the transition bracket 12 are detachably connected, and the transition bracket 12 is pivotally connected to the pull rod 32. Since the handle body 11 and the transition bracket 12 are detachably connected, the handle body 11 and the transition bracket 12 can be manufactured separately. On the one hand, this reduces the manufacturing difficulty of the outer door handle 1; on the other hand, when the handle body 11 needs to be replaced, the handle body 11 and the transition bracket 12 can be directly separated to improve the replacement efficiency of the handle body 11.

[0055] For example, such as Figure 8 As shown, the handle body 11 and the transition bracket 12 are connected by threaded parts, which facilitates the assembly and disassembly of the handle body 11 and the transition bracket 12. There can be two threaded parts, which are arranged on the transition bracket 12 in the front-to-back direction and staggered in the vertical direction to improve the firmness of the connection between the handle body 11 and the transition bracket 12.

[0056] Optionally, such as Figures 6 to 8 As shown, the outer door handle 1 is provided with an ear seat 121, and the ear seat 121 has a through hole (not shown). Figure 8 As shown, the ear seat 121 is mounted on the transition bracket 12 of the outer door handle 1. One end of the pull rod 32 has a bent section 321, which passes through the through hole in the vertical direction and is rotatable relative to the through hole. The linkage assembly 3 also includes a limiting sleeve 33. Part of the limiting sleeve 33 is located between the outer wall of the bent section 321 and the inner wall of the through hole and engages with the ear seat 121. The other part of the limiting sleeve 33 engages with the pull rod 32. It can be understood that the limiting sleeve 33 can prevent the bent section 321 from dislodging from the ear seat 121 to ensure the reliability of the connection between the outer door handle 1 and the pull rod 32. In addition, since the limiting sleeve 33 engages with the pull rod 32, it is easy to assemble the limiting sleeve 33 onto the pull rod 32.

[0057] For example, the limiting sleeve 33 is made of non-metallic material to avoid the problem of abnormal noise caused by friction at the connection position of the limiting sleeve 33 with the ear seat 121 and the pull rod 32.

[0058] Optionally, such as Figures 4 to 6As shown, the outer door handle 1 includes a first pivot 13 and a first elastic element 14. The first pivot 13 passes through the handle body 11 in a vertical direction, and the handle body 11 can rotate relative to the first pivot 13 about a first axis. The first elastic element 14 is sleeved on the first pivot 13 and connected to the outer door handle 1, and is used to drive the outer door handle 1 to reset. The reset position of the outer door handle 1 is the position where the outer door handle 1 is in contact with the outer door panel 51. The first axis is collinear with the axis of the first pivot 13, and the handle body 11 is rotatably connected to the first pivot 13. When the user releases the outer door handle 1, the outer door handle 1 can reset under the action of the first elastic element 14, thereby improving the convenience of using the outer door handle 1.

[0059] For example, the first elastic element 14 is a torsion spring, one end of the first elastic element 14 is connected to the handle body 11, and the other end of the first elastic element 14 is connected to the outer door panel 51.

[0060] Optionally, such as Figure 4 and Figure 5 As shown, the outer door handle 1 has a first end 101 and a second end 102 in its extending direction. The first end 101 is connected to the pull rod 32. A first axis is located between the first end 101 and the second end 102, and the first axis is arranged closer to the first end 101. It can be understood that the first axis is arranged closer to the first end 101 than the second end 102, which makes it easier for the user to pull the outer door handle 1 and reduces the range of motion of the pull rod 32, making the door lock system more compact.

[0061] like Figures 4 to 7 As shown, the door lock 2 includes a door lock body 21 and a lever 22. The lever 22 is connected to the door lock body 21 and can swing in the inward and outward directions of the car door 5, so that the door lock body 21 can move between the open and closed positions. The adapter 31 is connected to the lever 22 and can drive the lever 22 to swing. It can be understood that when the lever 22 swings in the inward and outward directions of the car door 5, the latch inside the door lock body 21 can be opened and closed. The door lock system of this utility model, by designing the door lock 2 with the above structure, facilitates the linkage between the adapter 31 and the door lock 2, and has a reasonable spatial arrangement, so as to integrate the door lock system into the car door 5.

[0062] Optionally, such as Figure 4 and Figure 5 As shown, the lever 22 has a first strip hole 221 inside, which extends in the vertical direction. The adapter 31 includes an adapter body 311 and a first fixed shaft 312. The first fixed shaft 312 is connected to the adapter body 311 and passes through the first strip hole 221. When the adapter 31 drives the lever 22 to swing, the first fixed shaft 312 can slide relative to the first strip hole 221 in the vertical direction.

[0063] Understandably, when the lever 32 pushes the adapter 31 to rotate around the second axis, under the constraint of the first fixed shaft 312 and the first slotted hole 221, the adapter 31 can provide a force to the lever 22 along the thickness direction of the door 5 (the inward and outward direction of the door 5), thereby driving the lever 22 to swing. When the lever 22 swings, the first slotted hole 221 will float in the up-down direction, while the first fixed shaft 312 can slide freely relative to the first slotted hole 221 in the up-down direction. This avoids the problem of jamming when the adapter 31 and the lever 22 are linked, and helps to improve the smoothness of the linkage between the adapter 31 and the door lock 2.

[0064] For example, such as Figure 5 As shown, the first fixed shaft 312 extends along the front and rear of the door 5, and the front end of the first fixed shaft 312 is fixedly connected to the adapter body 311.

[0065] In some embodiments, such as Figures 4 to 6 As shown, the door lock system also includes an inner door handle 4, which is connected to the adapter 31. It is understood that the inner door handle 4 can also drive the adapter 31 to rotate; that is, both the outer door handle 1 and the inner door handle 4 can drive the adapter 31 to rotate, thus switching the door lock 2 between the open and closed positions. This allows for a compact door lock system design, reduces the number of parts used, and lowers manufacturing costs.

[0066] like Figure 2 As shown, the adapter 31 can be located inside the receiving cavity 54 of the door 5, that is, the adapter 31 can be hidden, and the end of the inner door handle 4 can extend out of the door 5 and be located on the inner side of the door 5.

[0067] Optionally, the inner door handle 4 is flexible. For example, the inner door handle 4 can be a pull strap made of fabric or rubber. When the outer door handle 1 drives the adapter 31 to rotate, because the inner door handle 4 is flexible, the end of the inner door handle 4 can remain stationary when the door 5 is opened outward, which helps to improve the user experience.

[0068] Optionally, such as Figures 4 to 6 As shown, the pull rod 32 is provided with a second strip hole 322, which extends along the length of the pull rod 32. The adapter 31 includes an adapter body 311 and a second fixed shaft 313. The second fixed shaft 313 is connected to the adapter body 311 and passes through the second strip hole 322 in the vertical direction. The second fixed shaft 313 can rotate and slide relative to the second strip hole 322. The second strip hole 322 has a first side 3221 close to the outer door handle 1 and a second side 3222 away from the outer door handle 1. When the outer door handle 1 is reset, the second fixed shaft 313 is spaced apart from the second side 3222.

[0069] like Figures 4 to 6 As shown, when the inner door handle 4 drives the adapter 31 to rotate, since the second fixed shaft 313 and the second side 3222 are spaced a certain distance apart, the adapter 31 will not drive the pull rod 32 to move synchronously when it rotates. That is, the second fixed shaft 313 can slide in the second strip hole 322, so that the outer door handle 1 does not move when the car door 5 is opened inward, which is beneficial to improving the user experience.

[0070] For example, when the inner door handle 4 drives the adapter 31 to rotate to the limit position, the second fixed shaft 313 and the second side 3222 just come into contact, which helps to shorten the length of the pull rod 32 so that the arrangement of the adapter 31 and the pull rod 32 is more compact.

[0071] like Figure 5 and Figure 6 As shown, when the outer door handle 1 is reset, the second fixed shaft 313 abuts against the first side 3221. When the user pulls the outer door handle 1 outward, since the second fixed shaft 313 abuts against the first side 3221 of the second strip hole 322, the pull rod 32 can immediately drive the second fixed shaft 313 (adapter 31) to move, which helps to improve the sensitivity of the outer door handle 1 when in use.

[0072] Optionally, such as Figure 6 As shown, the linkage assembly 3 also includes a second elastic element 34, which is sleeved on the second fixed shaft 313 and abuts against the adapter body 311 and the pull rod 32. The second elastic element 34 has an elastic force that causes the adapter body 311 and the pull rod 32 to move away from each other, so that the pull rod 32 has a certain elastic resistance when moving relative to the second fixed shaft 313, thereby preventing the pull rod 32 from wobbling in the vertical direction and improving the stability of the linkage assembly 3 during operation.

[0073] For example, the second elastic element 34 is a cylindrical spring.

[0074] Optionally, such as Figures 4 to 7 As shown, the linkage component 3 also includes a third elastic element 35, which is connected to the adapter 31. The third elastic element 35 has an elastic force that drives the adapter 31 to close the door lock 2. Thus, when the user releases the inner door handle 4, the adapter 31 can automatically reset under the action of the third elastic element 35, so that the door lock 2 switches to the closed position, thereby improving the convenience of using the door lock system.

[0075] For example, such as Figures 4 to 7As shown, the linkage assembly 3 also includes a second pivot 36, which passes through the adapter 31 and the door frame 53 in the vertical direction. The second axis is the axis of the second pivot 36. The third elastic member 35 is a torsion spring and is sleeved on the second pivot 36. One end of the third elastic member 35 is connected to the adapter 31, and the other end of the third elastic member 35 is connected to the door frame 53.

[0076] like Figures 1 to 4 As shown, another embodiment of the present invention provides a door assembly including a door 5 and a door lock system. The door 5 includes an outer door panel 51, an inner door panel 52, and a door frame 53. The inner door panel 52 is located inside the outer door panel 51, and a receiving cavity 54 is provided between the inner door panel 52 and the outer door panel 51. The door frame 53 is located in the receiving cavity 54. The door lock system is the door lock system of the present invention. The door lock 2 is installed on the door frame 53, and the outer door handle 1 is located on the outer side of the outer door panel 51.

[0077] In the embodiment of this utility model, the door assembly allows the user to operate the outer door handle 1 and rotate it around the first axis. Under the linkage of the pull rod 32, the adapter 31 can rotate synchronously to switch the door lock 2 between the open and closed positions. The door lock system of this utility model can complete the opening and closing of the door lock 2 through the transmission of the pull rod 32 and the adapter 31. This makes the structural design of the door lock system simple, the transmission stroke short, and facilitates the placement of the door lock system inside the car door 5, resulting in better performance.

[0078] Optionally, such as Figure 3 and Figure 4 As shown, the adapter 31 is rotatably connected to the door frame 53, and the adapter 31 is located within the receiving cavity 54. This allows for a compact arrangement of the door lock system within the door 5, shortening the transmission stroke of the adapter 31. Figure 3 As shown, the second axis extends along the vertical direction of the door frame 53.

[0079] like Figure 3 and Figure 4 As shown, the door lock system also includes an inner door handle 4. The inner door handle 4 is flexible, with one end connected to the adapter 31 and the other end extending through the inner door panel 52. When the outer door handle 1 drives the adapter 31 to rotate, due to the flexibility of the inner door handle 4, the other end (end end) of the inner door handle 4 remains stationary when the door 5 is opened outward, which helps to improve the user experience.

[0080] Optionally, such as Figure 3As shown, the inner side of the outer door panel 51 has a limiting boss 511. The outer door handle 1 includes a handle body 11 and a transition bracket 12. The handle body 11 is connected to the transition bracket 12, and the transition bracket 12 is pivotally connected to the pull rod 32. When the handle body 11 is reset, the transition bracket 12 abuts against the limiting boss 511, thereby constraining the position of the outer door handle 1 when it is reset and limiting the movement of the pull rod 32, which helps to improve the accuracy of the movement of the outer door handle 1 and the pull rod 32.

[0081] Another embodiment of the vehicle of this utility model includes the door lock system or door assembly of the present utility model. The technical advantages of the vehicle of this utility model embodiment are the same as those of the door lock system or door assembly of the above embodiments, and will not be repeated here.

[0082] For example, the vehicle is an all-terrain vehicle.

[0083] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0084] Furthermore, 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 indicated technical features.
