[0002] With the development of the automotive industry, electric sliding doors are becoming increasingly popular in the market due to their labor-saving and intelligent features compared to manual sliding doors. They also feature anti-pinch and hover functions. Electric sliding doors are a manual sliding door with the addition of a drive mechanism, front and rear steering wheel structures, front and rear cables, a front cable bracket, and a rear cable bracket. The front cable bracket supports and guides the front cable, while the rear cable bracket supports and guides the rear cable. The drive mechanism pulls the front or rear cable to drive the hinge structure to slide along the center guide rail. The hinge structure then simultaneously drives the sliding door, creating an electric sliding door. The front steering wheel structure guides the routing of the front cable, while the rear steering wheel structure guides the routing of the rear cable.

The front wire bypasses the front steering wheel of the front steering wheel structure and is connected to the front wire bracket, which can effectively reduce the angle between the part of the front wire located between the front steering wheel and the front wire bracket and the moving direction of the hinge structure, so that the efficiency and effect of moving the hinge structure by pulling the front wire can be effectively improved. However, due to the continuous improvement of the requirements for the interior design of the vehicle and the need to ensure the intrusion amount of the middle guide rail into the inner side of the vehicle body, it is necessary to reduce the distance between the interior panel and the inner sheet metal, so that the arrangement position of the above-mentioned front steering wheel structure no longer meets the requirements, resulting in the setting position of the above-mentioned front wire bracket being unable to meet the efficiency and effect of the front wire pulling the hinge structure to move.

[0046] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0048] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0049] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0050] In the current existing technology, the front wire bracket and the rear wire bracket are usually connected to the two sides of the hinge structure respectively to form a combined structure, the front steering wheel structure is set at the front end of the middle guide rail, and the front wire bracket is set close to the front end of the middle guide rail relative to the hinge structure. The front wire bypasses the front steering wheel of the front steering wheel structure and is connected to the front wire bracket, which can effectively reduce the angle between the part of the front wire located between the front steering wheel and the front wire bracket and the moving direction of the hinge structure, so that the efficiency and effect of moving the hinge structure by pulling the front wire can be effectively improved. However, due to the continuous improvement of the requirements for the interior design of the vehicle and the need to ensure the intrusion amount of the middle guide rail into the inner side of the vehicle body, it is necessary to reduce the distance between the interior panel and the inner sheet metal, so that the arrangement position of the above-mentioned front steering wheel structure no longer meets the requirements, resulting in the setting position of the above-mentioned front wire bracket being unable to meet the efficiency and effect of the front wire pulling the hinge structure to move.

[0051] like Figure 1-5 As shown, the present invention provides a sliding door hinge structure 100. The sliding door hinge structure 100 includes a hinge body 1, which includes a hinge portion 11 and a roller mounting portion 12. The hinge portion 11 is configured to be hinged to the sliding door, and the roller mounting portion 12 is mounted with a roller assembly 3. A cable connection portion 2 is connected to the roller mounting portion 12, with the roller mounting portion 12 and the cable connection portion 2 being located on the same side and facing away from the hinge portion 11. The cable connection portion 2 is configured to connect to two sub-cables of the cable assembly, and is located farther from the front end of the middle guide rail 200 relative to the roller mounting portion 12.

[0052] Before the sliding door hinge structure 100 is put into operation, the roller assembly 3 of the roller mounting portion 12 is rolled and assembled on the middle guide rail 200, the hinge portion 11 is hinged to the sliding door, and the two sub-pull cables of the pull wire group are connected to the pull wire connection portion 2. The pull wire connection portion 2 is pulled by the pull wire group, driving the roller assembly 3 to roll on the middle guide rail, thereby driving the sliding door hinge structure 100 to move synchronously along the extension direction of the middle guide rail 200, so as to drive the sliding door to slide open and close. Among them, by arranging the roller mounting portion 12 and the pull wire connection portion 2 to be distributed on the same side and both facing away from the hinge portion 11, it can be understood that the roller mounting portion 12 and the pull wire connection portion 2 are both facing the middle guide rail 200, so that the roller assembly 3 of the roller mounting portion 12 can be effectively rolled and connected to the middle guide rail 200, the two sub-pull cables of the pull wire group can be at least partially accommodated in the middle guide rail 200, and the hinge portion 11 can be effectively hinged to the sliding door. Secondly, by setting the wire connection part 2 to be connected to the two sub-wires of the wire group, and the wire connection part 2 is far away from the front end of the middle guide rail 200 relative to the roller mounting part 12, it can be understood that the connection points of the two sub-wires connected to the wire connection part 2 are far away from the front end of the middle guide rail 200 relative to the hinge body 1, so that the ends of the two sub-wires connected to the wire connection part 2 are partially accommodated in the middle guide rail 200, so that the ends of the two sub-wires connected to the wire connection part 2 are roughly parallel to the extension direction of the middle guide rail 200, that is, the ends of the two sub-wires connected to the wire connection part 2 are roughly parallel to the moving direction of the sliding door hinge structure, so that when the wire connection part 2 is moved by any sub-wire, it can effectively drive the roller group 3 to roll on the middle guide rail 200, so that the sliding door hinge structure moves synchronously along the extension direction of the middle guide rail 200, and can effectively ensure the efficiency and effect of the movement of the sliding door hinge structure.

[0053] in, Figure 1 and Figure 3-5 The ab direction is the height direction of the vehicle body.

[0054] Among them, such as Figure 1-4 As shown, the roller assembly 3 includes guide rollers 31 and load-bearing rollers 32. Along the height direction of the vehicle body, the guide rollers 31 are rollingly connected to the top end of the center rail 200, while the load-bearing rollers 32 are rollingly supported on the bottom end of the center rail 200. This arrangement ensures that when the guide rollers 31 and load-bearing rollers 32 roll on the center rail 200, they drive the sliding door hinge structure 100 to move synchronously along the extension direction of the center rail 200, ensuring that the sliding door hinge structure 100 does not tip over. It should be understood that the height direction of the vehicle body is parallel to the height direction of the center rail 200.

[0055] Specifically, if Figure 4 As shown, the middle guide rail 200 includes a guide rail groove 210 with a door-shaped cross section, and the guide roller 31 rolls in the guide rail groove 210. Figure 1 and Figure 3-5As shown, the middle guide rail 200 further includes a guide rail plate 220, which is spaced and opposite to the opening of the guide rail groove 210 along the height direction of the vehicle body, and the load-bearing roller 32 is rollingly supported on the guide rail plate 220. This arrangement is provided to achieve rolling assembly of the roller group 3 on the middle guide rail 200.

[0056] Optionally, there are multiple guide rollers 31, which are spaced apart and all roll in the guide rail groove 210. There are multiple load-bearing rollers 32, which are spaced apart and all roll on the guide rail plate 220. This arrangement can further improve the stability of the roller group 3 in driving the sliding door hinge structure 100 to move. Figure 2 As shown, the number of guide rollers 31 is exemplarily two, the number of load-bearing roller 32 is one, and the load-bearing roller 32 is located between the two guide rollers 31 .

[0057] Preferably, the hinged portion 11, the roller mounting portion 12 and the wire connecting portion 2 are integrally formed. This eliminates the need for additional connectors compared to the prior art, effectively reducing the number of components, facilitating assembly, and effectively improving the structural strength of the sliding door hinge structure 100. Secondly, the setting position of the wire connecting portion 2 of the integrally formed sliding door hinge structure 100 is fixed, thereby effectively improving the setting position accuracy of the wire connecting portion 2. As an alternative, the hinged portion 11 and the roller mounting portion 12 are integrally formed, and the wire connecting portion 2 is detachably connected to the roller mounting portion 12. It is also possible to combine the hinged portion 11, the roller mounting portion 12 and the wire connecting portion 2 to form a sliding door hinge structure.

[0058] Among them, such as Figure 3-5 As shown, the cable connecting portion 2 is located between the guide roller 31 and the load-bearing roller 32. As an alternative, Figure 1 and Figure 2 As shown, the cable connecting portion 2 is located on the side of the load-bearing roller 32 away from the guide roller 31. This arrangement allows the ends of the two sub-cables connected to the cable connecting portion 2 to be partially well accommodated in the middle guide rail 200, and the ends of the two sub-cables connected to the cable connecting portion 2 to be roughly parallel to the moving direction of the sliding door hinge structure.

[0059] Among them, such as Figure 1-3 As shown, the cable connecting portion 2 includes two sub-cable connecting portions arranged in a straight line and connected as a whole. The two sub-cable connecting portions are arranged and connected to the two sub-cables in a one-to-one correspondence. Figure 1-3As shown, the two sub-pull wire connections are respectively the first pull wire connection 21 and the second pull wire connection 22. The first pull wire connection 21 and the second pull wire connection 22 are arranged at intervals roughly along the extension direction of the pull wire connection part 2. That is, the pull wire connection part 2 extends roughly in an "I" shape. The two sub-pull wires are respectively the front pull wire 310 and the rear pull wire 320. One of the first pull wire connection 21 and the second pull wire connection 22 is used to connect with the front pull wire 310 of the pull wire group, and the other is used to connect with the rear pull wire 320 of the pull wire group. It is arranged in this way to realize the connection of the front pull wire 310 and the rear pull wire 320 of the pull wire group to the pull wire connection part 2 respectively.

[0060] As an alternative, Figure 5 As shown, the cable connection portion 2 includes two sub-cable connection portions spaced apart along the height direction of the vehicle body, and the two sub-cable connection portions are arranged and connected to the two sub-cables in a one-to-one correspondence. Figure 5 As shown, the two sub-pull wire connections are respectively the first pull wire connection 21 and the second pull wire connection 22. The first pull wire connection 21 and the second pull wire connection 22 are spaced apart along the height direction of the vehicle body. The two sub-pull wires are respectively the front pull wire 310 and the rear pull wire 320. One of the first pull wire connection 21 and the second pull wire connection 22 is used to connect with the front pull wire 310 of the pull wire group, and the other is used to connect with the rear pull wire 320 of the pull wire group. With such an arrangement, it is also possible to connect the front pull wire 310 and the rear pull wire 320 of the pull wire group to the pull wire connection 2 respectively.

[0061] Specifically, when the two sub-pull wire connection parts are the first pull wire connection part 21 and the second pull wire connection part 22 arranged in an "I" shape, the first pull wire connection part 21 and the second pull wire connection part 22 are both integrally formed on the hinge body 1. As an alternative, when the two sub-pull wire connection parts are the first pull wire connection part 21 and the second pull wire connection part 22 arranged in an "I" shape, the first pull wire connection part 21 and the second pull wire connection part 22 are respectively detachably connected to the hinge body 1. Or, when the two sub-pull wire connection parts are the first pull wire connection part 21 and the second pull wire connection part 22 arranged in an "I" shape, the first pull wire connection part 21 and the second pull wire connection part 22 are respectively welded to the hinge body 1.

[0062] Specifically, when the two sub-pull wire connections are the first pull wire connection 21 and the second pull wire connection 22 that are spaced apart along the height direction of the vehicle body, the first pull wire connection 21 and the second pull wire connection 22 are both integrally formed on the hinge body 1. As an alternative, when the two sub-pull wire connections are the first pull wire connection 21 and the second pull wire connection 22 that are spaced apart along the height direction of the vehicle body, the first pull wire connection 21 and the second pull wire connection 22 are respectively detachably connected to the hinge body 1. Or, when the two sub-pull wire connections are the first pull wire connection 21 and the second pull wire connection 22 that are spaced apart along the height direction of the vehicle body, the first pull wire connection 21 and the second pull wire connection 22 are respectively welded to the hinge body 1.

[0063] It is understandable that if Figure 3-5 As shown, when the cable connection portion 2 is located between the guide roller 31 and the load-bearing roller 32, the first cable connection portion 21 and the second cable connection portion 22 can be arranged in a straight line or spaced apart along the height direction of the vehicle body. Figure 1 and Figure 2 As shown, when the cable connection portion 2 is located on the side of the load-bearing roller 32 away from the guide roller 31, the first cable connection portion 21 and the second cable connection portion 22 can be arranged in a straight line. When the cable connection portion 2 is located on the side of the load-bearing roller 32 away from the guide roller 31, the first cable connection portion 21 and the second cable connection portion 22 can also be arranged to be spaced apart along the height direction of the vehicle body.

[0064] In this embodiment, if Figure 1 、 Figure 3 and Figure 5 As shown, the first pull wire connection portion 21 is exemplarily connected to the front pull wire 310, and the second pull wire connection portion 22 is connected to the rear pull wire 320. In other embodiments, the first pull wire connection portion can also be connected to the rear pull wire, and the second pull wire connection portion can be connected to the front pull wire.

[0065] Among them, such as Figure 6 and Figure 7 As shown, one of the sub-cable connector and the end of the sub-cable is equipped with a post 41, and the other with a socket 42. The post 41 engages with the socket 42 along the height of the vehicle body and is at least partially supported on the sub-cable connector. This arrangement eliminates the need for additional connectors and facilitates assembly and disassembly of the sub-cable connector and the sub-cable.

[0066] It is understandable that one of each sub-pull wire connection portion and the corresponding sub-pull wire is provided with a plug post 41, and the other is provided with a socket 42. The connection methods of the two sub-pull wire connection portions and the corresponding sub-pull wires can be the same or different.

[0067] Specifically, if Figure 6As shown, when the sub-pull cable connection portion is provided with a plug post 41, a limit sleeve is fixedly provided at the end of the sub-pull cable, and the limit sleeve is provided with a socket 42. Along the height direction of the vehicle body, when the plug post 41 is plugged into the socket 42, the limit sleeve is supported on the sub-pull cable connection portion.

[0068] Specifically, if Figure 7 As shown, when the sub-pull wire connection portion is provided with an insertion hole 42, the sub-pull wire connection portion includes an upper connecting plate and a lower connecting plate that are spaced and connected along the height direction of the vehicle body, and a wire passing space is formed between the upper connecting plate and the lower connecting plate. The insertion hole 42 includes a first sub-hole 421 provided on the upper connecting plate, a second sub-hole 422 provided on the lower connecting plate, and a wire passing hole 423 provided on the lower connecting plate, and the wire passing hole 423 is connected to the second sub-hole 422. The first sub-hole 421 and the second sub-hole 422 are opposite to each other and are both connected to the wire passing space. The plug 41 includes a plug-in portion 411 and a lap portion 412 that are connected, and the lap portion 412 is also connected to the end of the sub-pull wire. The sub-pull wire can pass through the wire passing hole 423 so that the two ends of the plug-in portion 411 along the axial direction are respectively plugged into the first sub-hole 421 and the second sub-hole 422. After the two ends of the inserting portion 411 along the axial direction are respectively inserted into the first sub-hole 421 and the second sub-hole 422 , the inserting portion 411 is rotated so that the overlapping portion 412 is overlapped and supported on the lower connecting plate.

[0069] Among them, such as Figure 1 and Figure 3-5 As shown, an escape space 13 is formed between the hinge portion 11 and the roller mounting portion 12. Specifically, when the sliding door slides to the closed position, the escape space 13 avoids the vehicle body structure to avoid interference and damage to the vehicle body structure.

[0070] The present invention also provides an electric sliding door drive system, comprising a central guide rail 200 and a cable assembly. The central guide rail 200 is fixedly connected to the outer side of the vehicle body's outer sheet metal, and also includes the aforementioned sliding door hinge structure 100. By employing the aforementioned sliding door hinge structure 100, the efficiency and effectiveness of any cable assembly in driving the sliding door hinge structure can be effectively guaranteed, thereby effectively ensuring the operating performance of the electric sliding door drive system. Furthermore, the number of components in the electric sliding door drive system can be effectively reduced, improving the efficiency of assembling the electric sliding door drive system.

[0071] in, Figure 8 The cd direction is the length direction of the vehicle body. Figure 8 The ef direction is the width direction of the vehicle body.

[0072] Specifically, if Figure 8As shown, the middle guide rail 200 includes a long straight guide rail section 230 extending along the length of the vehicle body, and a short straight guide rail section 240 arranged at an obtuse angle with the long straight guide rail section 230 and smoothly transitioning therefrom. Along the length of the vehicle body, the short straight guide rail section 240 is located at the front end of the long straight guide rail section 230. Along the width of the vehicle body, the short straight guide rail section 240 extends inwardly of the vehicle body. A guide rail groove 210 extends through the short straight guide rail section 240 and the long straight guide rail section 230 along the extension direction of the middle guide rail 200. Guide rail plates 220 are also formed on the short straight guide rail section 240 and the long straight guide rail section 230 along the extension direction of the middle guide rail 200.

[0073] Specifically, if Figure 8 As shown, the electric sliding door drive system also includes a drive mechanism 400, a front steering structure 500 and a rear steering structure 600. One end of the two sub-pull cables is respectively connected to the cable connecting portion 2. The other end of one of the sub-pull cables passes around the front steering wheel of the front steering structure 500 and is drive-connected to the drive mechanism 400. The other end of the other sub-pull cable passes around the rear steering wheel of the rear steering structure 600 and is drive-connected to the drive mechanism 400. The drive mechanism 400 can selectively pull one of the two sub-pull cables. The front steering wheel is used to guide the routing direction of one of the sub-pull cables. The rear steering wheel is used to guide the routing direction of the other sub-pull cable.

[0074] In this embodiment, one end of the front cable 310 is exemplarily connected to the first cable connection portion 21, and one end of the rear cable 320 is connected to the second cable connection portion 22. The other end of the front cable 310 bypasses the front steering wheel of the front steering structure 500 and is drive-connected to the drive mechanism 400. The other end of the rear cable 320 bypasses the rear steering wheel of the rear steering structure 600 and is drive-connected to the drive mechanism 400. The front steering wheel is used to guide the routing direction of the front cable 310. The rear steering wheel is used to guide the routing direction of the rear cable 320.

[0075] In this embodiment, the drive mechanism 400 includes a drive motor fixedly connected to the inner sheet metal, and a winding wheel rotatably connected to the output end of the drive motor, and the drive motor can drive the winding wheel to rotate around its own central axis. The other end of the front pull wire 310 passes around the front steering wheel and is connected to the winding wheel. The other end of the rear pull wire 320 passes around the rear steering wheel and is connected to the winding wheel. When the drive motor drives the winding wheel to rotate around its own central axis, one of the front pull wire 310 and the rear pull wire 320 is pulled and wound around the winding wheel, and the other is unwound.

[0076] Specifically, as the front cable 310 is pulled and wound around the reel, it drives the sliding door hinge structure 100 from the long straight guide rail section 230 to the short straight guide rail section 240, thereby driving the sliding door to move forward in a synchronous manner along the length of the vehicle body, thereby enabling the sliding door to close. As the rear cable 320 is pulled and wound around the reel, it drives the sliding door hinge structure 100 from the short straight guide rail section 240 to the long straight guide rail section 230, thereby driving the sliding door to move backward in a synchronous manner along the length of the vehicle body, thereby enabling the sliding door to open.

[0077] Specifically, the front bracket of the front steering structure 500 is fixedly connected to the inner sheet metal of the vehicle body. Alternatively, the front bracket of the front steering structure 500 is integrally formed with the inner sheet metal of the vehicle body. The front steering wheel is rotatably connected to the front bracket.

[0078] Further, if Figure 8 As shown, the front steering structure 500 also includes a first protective shell, which includes two first sub-shells 510. A first accommodating cavity is formed between the two first sub-shells 510, and two first wire outlet holes are connected to the first accommodating cavity. The front steering wheel is accommodated in the first accommodating cavity, and one end of the front pull wire 310 passes through one of the first wire outlet holes, the first accommodating cavity and the other first wire outlet hole in sequence and is connected to the first pull wire connecting portion 21. It can protect the front steering wheel and the front pull wire 310. Among them, the two first sub-shells 510 are detachably connected to the inner sheet metal by bolts and nuts.

[0079] Specifically, the rear bracket of the rear steering structure 600 is fixedly connected to the inner sheet metal of the vehicle body. Alternatively, the rear bracket of the rear steering structure 600 is integrally formed with the inner sheet metal of the vehicle body. The rear steering wheel is rotatably connected to the rear bracket.

[0080] Further, if Figure 8 As shown, the rear steering structure 600 also includes a second protective shell, which includes two second sub-shells 610. A second accommodating cavity is formed between the two second sub-shells 610, and two second wire outlet holes are connected to the second accommodating cavity. The rear steering wheel is accommodated in the second accommodating cavity, and one end of the rear cable 320 passes through one of the second wire outlet holes, the second accommodating cavity, and the other second wire outlet hole in sequence and is connected to the second cable connection portion 22. It can protect the rear steering wheel and the rear cable 320. The two second sub-shells 610 are detachably connected to the inner sheet metal by bolts and nuts.

[0081] Furthermore, the front steering structure 500 is located between the interior panel and the outer sheet metal. The rear steering structure 600 is located between the interior panel and the outer sheet metal. The middle guide rail 200 is located away from the inner sheet metal relative to the outer sheet metal along the width direction of the vehicle body. In other words, the middle guide rail 200 is located outside the vehicle body.

[0082] It can be understood that the front steering structure 500 , the rear steering structure 600 and the middle guide rail 200 are independent of each other.

[0083] Among them, due to the continuous improvement of the demand for vehicle interior styling and the need to ensure the intrusion of the center guide rail into the inner side of the vehicle body, it is necessary to reduce the distance between the interior panel and the inner sheet metal, resulting in the conventional layout of the front steering wheel structure cannot meet the demand.

[0084] Therefore Figure 8 As shown, the front steering structure 500 is positioned behind the front end of the center rail 200 along the vehicle's length. Along the vehicle's width, the front steering structure 500 partially extends beyond the front end of the center rail 200. This arrangement effectively addresses the placement of the front steering structure 500 and ensures that the front steering wheel can guide the routing of the front cable 310. Furthermore, along the vehicle's width, it effectively shortens the gap between the inner sheet metal and the interior trim panel, thereby effectively preventing any impact on the interior design and significantly increasing the vehicle's interior space.

[0085] Specifically, when the front cable 310 and the rear cable 320 are assembled, the front cable 310 is partially located within the middle rail 200, and the rear cable 320 is also partially located within the middle rail 200. This allows the front cable 310 to be tensioned under the guidance of the middle rail 200 and the front steering wheel. Similarly, the rear cable 320 is tensioned under the guidance of the middle rail 200 and the rear steering wheel, thus meeting the operational requirements of the front and rear cables 310 and 320.

[0086] The present invention also provides a vehicle including the above-described electric sliding door drive system. By employing the above-described electric sliding door drive system, the layout problem of the front steering structure 500 can be effectively solved, and the distance between the inner sheet metal and the interior trim panel can be effectively shortened, thereby effectively avoiding the impact on the interior design and effectively increasing the interior space of the vehicle.

[0087] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
