[0035] 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.

[0036] 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.

[0037] like Figures 1 to 5 As shown, the door lock system of this utility model embodiment includes: an inner door handle 1, a door lock 2, and a linkage component 3. The linkage component 3 includes a converter 31, which is connected to the door lock 2. The converter 31 can rotate around a first axis to drive the door lock 2 to move between an open position and a closed position. One end of the inner door handle 1 is connected to the converter 31, and the other end of the inner door handle 1 extends out of the car door 5. The inner door handle 1 can pull the converter 31 to rotate.

[0038] According to the door lock system of this embodiment, the user can pull the other end of the inner door handle 1 to cause the adapter 31 to rotate around the first axis. Since the adapter 31 is connected to the door lock 2, the adapter 31 can synchronously drive the door lock 2 to switch between the open and closed positions. Furthermore, the door lock system can be designed with inner door handles 1 of different lengths according to different types of vehicle doors 5 to expand the adaptability of the door lock system. Therefore, the door lock system of this embodiment has a simple structural design, which is beneficial for the planning and layout of the door lock system within the vehicle door 5, and provides good performance.

[0039] Optionally, the inner door handle 1 is flexible. For example, the inner door handle 1 can be a pull strap made of fabric or rubber. When the door 5 is opened outward, even if the adapter 31 rotates, the other end (end) of the inner door handle 1 can remain almost stationary, which helps to improve the user experience.

[0040] like Figure 5 and Figure 6 As shown, the first axis (such as Figure 6 The axis of the first pivot 36 extends along the vertical direction of the door 5. It can be understood that the rotation axis of the adapter 31 extends along the vertical direction, which facilitates the assembly of the adapter 31 and makes the linkage between the adapter 31 and the door lock 2 better.

[0041] Optionally, such as 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.

[0042] like Figure 4 , Figure 5 and Figure 7 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.

[0043] Understandably, when the lever 32 pushes the adapter 31 to rotate around the first 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 can avoid the problem of jamming when the adapter 31 and the lever 22 are linked, and improve the smoothness of the linkage between the adapter 31 and the door lock 2.

[0044] 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.

[0045] Optionally, such as Figures 4 to 6 As shown, the linkage component 3 also includes a first elastic element 34, which is connected to the adapter 31. The first elastic element 34 has an elastic force that drives the adapter 31 to close the door lock 2. Thus, when the user releases the inner door handle 1, the adapter 31 can automatically reset under the action of the first elastic element 34, so that the door lock 2 switches to the closed position, thereby improving the convenience of using the door lock system.

[0046] For example, such as Figures 4 to 6 As shown, the linkage component 3 also includes a first pivot 36, which passes through the adapter 31 and the vehicle frame door 53 in the vertical direction. The first axis is the axis of the first pivot 36. The first elastic member 34 is a torsion spring and is sleeved on the first pivot 36. One end of the first elastic member 34 is connected to the adapter 31, and the other end of the first elastic member 34 is connected to the vehicle frame door 53.

[0047] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, the door lock system also includes an outer door handle 4, and the linkage component 3 includes a pull rod 32. The outer door handle 4 is connected to the adapter 31 via the pull rod 32. The outer door handle 4 can drive the pull rod 32 to rotate the adapter 31. It can be understood that the outer door handle 4 can also drive the adapter 31 to rotate. That is, both the outer door handle 4 and the inner door handle 1 can drive the adapter 31 to rotate, 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.

[0048] like Figures 4 to 6As shown, the outer door handle 4 can rotate around a second axis, which extends vertically. The outer door handle 4 is installed on the outer door panel 51 of the vehicle door 5. When the user pulls the outer door handle 4 outward, the outer door handle 4 can rotate horizontally around the second axis. At this time, the outer door handle 4 can directly drive the lever 32 to move, thereby driving the adapter 31 to rotate around the first axis. With the cooperation of the lever 32 and the adapter 31, the door lock 2 can be opened to unlock the vehicle door 5.

[0049] The user can operate the outer door handle 4 and rotate it around the second 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 embodiment 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 on the car door 5, resulting in better performance.

[0050] Optionally, such as Figures 4 to 6 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.

[0051] like Figures 4 to 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 4, 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 4, the pull rod 32, and the adapter 31 can form a multi-link structure, meaning the outer door handle 4 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.

[0052] like Figure 4 As shown, when the user pulls the outer door handle 4 outward, under the action of leverage, the outer door handle 4 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 first axis to open the door lock 2.

[0053] Optionally, such as Figure 5 , Figure 6 and Figure 9 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 along the vertical direction of the door 5. 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 4 and a second side 3222 away from the outer door handle 4. When the outer door handle 4 is reset, the second fixed shaft 313 is spaced apart from the second side 3222.

[0054] When the inner door handle 1 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 when the car door 5 is opened inward, the outer door handle 4 does not move, which is beneficial to improving the user experience.

[0055] For example, when the inner door handle 1 drives the adapter 31 to rotate to the limit position, the second fixed shaft 313 just contacts the second side 3222, 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.

[0056] like Figure 6 As shown, when the outer door handle 4 is reset, the second fixed shaft 313 abuts against the first side 3221. When the user pulls the outer door handle 4 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 4 when in use.

[0057] Optionally, such as Figure 6 As shown, the linkage assembly 3 also includes a second elastic element 35, 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 35 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.

[0058] For example, the second elastic element 35 is a cylindrical spring.

[0059] Optionally, such as Figures 4 to 6As shown, the outer door handle 4 includes a handle body 41 and a transition bracket 42. The handle body 41 and the transition bracket 42 are detachably connected, and the transition bracket 42 is pivotally connected to the pull rod 32. Since the handle body 41 and the transition bracket 42 are detachably connected, the handle body 41 and the transition bracket 42 can be manufactured separately. On the one hand, this reduces the manufacturing difficulty of the outer door handle 4; on the other hand, when the handle body 41 needs to be replaced, the handle body 41 and the transition bracket 42 can be directly separated, thereby improving the replacement efficiency of the handle body 41.

[0060] For example, the handle body 41 and the transition bracket 42 are connected by threaded parts, which facilitates the assembly and disassembly of the handle body 41 and the transition bracket 42. There can be two threaded parts, which are arranged on the transition bracket 42 in the front-to-back direction and staggered in the vertical direction to improve the firmness of the connection between the handle body 41 and the transition bracket 42.

[0061] Optionally, such as Figure 6 and Figure 9 As shown, the outer door handle 4 is provided with an ear seat 421, and the ear seat 421 has a through hole. The ear seat 421 is provided on the transition bracket 42 of the outer door handle 4. 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 provided between the outer wall of the bent section 321 and the inner wall of the through hole and is engaged with the ear seat 421. The other part of the limiting sleeve 33 is engaged 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 421 to ensure the reliability of the connection between the outer door handle 4 and the pull rod 32. In addition, since the limiting sleeve 33 is engaged with the pull rod 32, it is easy to assemble the limiting sleeve 33 onto the pull rod 32.

[0062] 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 421 and the pull rod 32.

[0063] Optionally, such as Figures 4 to 6 As shown, the outer door handle 4 includes a second pivot 43 and a third elastic element 44. The second pivot 43 passes through the handle body 41 in a vertical direction, and the handle body 41 can rotate relative to the second pivot 43 around a second axis. The third elastic element 44 is sleeved on the second pivot 43 and connected to the outer door handle 4. The third elastic element 44 is used to drive the outer door handle 4 to reset. The reset position of the outer door handle 4 is the position where the outer door handle 4 is in contact with the outer door panel 51. The second axis and the axis of the second pivot 43 are collinear, and the handle body 41 is rotatably connected to the second pivot 43. When the user releases the outer door handle 4, the outer door handle 4 can reset under the action of the third elastic element 44, thereby improving the convenience of using the outer door handle 4.

[0064] For example, the third elastic element 44 is a torsion spring, one end of the third elastic element 44 is connected to the handle body 41, and the other end of the third elastic element 44 is connected to the outer door panel 51.

[0065] Optionally, such as Figures 4 to 6 As shown, the outer door handle 4 has a first end 401 and a second end 402 in its extending direction. The first end 401 is connected to the pull rod 32, and a second axis is located between the first end 401 and the second end 402, with the second axis positioned closer to the first end 401. It can be understood that the second axis being positioned closer to the first end 401 than the second end 402 allows the user to pull the outer door handle 4 with less effort and reduces the range of motion of the pull rod 32, resulting in a more compact arrangement of the door lock system.

[0066] like Figures 1 to 4 As shown, another embodiment of the vehicle door assembly of this utility model includes: a vehicle door 5 and a door lock system. The vehicle door 5 includes an outer door panel 51, an inner door panel 52, and a frame door 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 frame door 53 is located in the receiving cavity 54. The door lock system is the door lock system of this utility model. The door lock 2 and the adapter 31 are both installed on the frame door 53. The adapter 31 is located in the receiving cavity 54 and is rotatable relative to the frame door 53. The other end of the inner door handle 1 extends out of the inner door panel 52.

[0067] According to the door assembly of this utility model embodiment, the user can pull the other end of the inner door handle 1 to cause the adapter 31 to rotate around the first axis. Since the adapter 31 is connected to the door lock 2, the adapter 31 can synchronously drive the door lock 2 to switch between the open and closed positions. Furthermore, the door lock system can be designed with inner door handles 1 of different lengths according to different types of car doors 5 to expand the adaptability of the door lock system. Therefore, the door lock system of this utility model embodiment has a simple structural design, which is beneficial for the planning and layout of the door lock system within the car door 5, and provides good performance.

[0068] like Figure 2 As shown, the adapter 31 is located inside the receiving cavity 54 of the door 5, that is, the adapter 31 can be hidden, and the inner door handle 1 can extend out of the receiving cavity 54 and be located on the inside of the door 5 so that the user can open the door 5 from the inside.

[0069] Optionally, such as Figure 3As shown, the inner side of the outer door panel 51 has a limiting boss 511. The outer door handle 4 includes a handle body 41 and a transition bracket 42. The handle body 41 is connected to the transition bracket 42, and the transition bracket 42 is pivotally connected to the pull rod 32. When the handle body 41 is reset, the transition bracket 42 abuts against the limiting boss 511, thereby constraining the position of the outer door handle 4 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 4 and the pull rod 32.

[0070] 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.
