Detailed Implementation

[0038] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0039] The frame-type body is formed by connecting multiple crossbeams and multiple longitudinal beams, and there is no mounting position for the sliding track of the electric sliding door, which makes it more difficult to realize the connection structure between the sliding track and the frame-type body. The sliding track component and vehicle provided in the embodiments of the present invention solve the connection problem between the frame-type body and the sliding track to a certain extent.

[0040] In a first aspect, embodiments of the present invention provide a slide rail assembly suitable for frame-type vehicle bodies, which realizes the connection between the slide rail assembly and the frame-type vehicle body. In particular, the upper slide rail adopts a hoisting installation, which expands the interior space of the vehicle and has a simple structure that is easy to promote.

[0041] Please combine Figure 1 , Figure 2 as well as Figure 5The slide rail assembly includes an upper slide rail assembly 100, a middle slide rail assembly 400, and a lower slide rail assembly 300. The upper slide rail assembly 100 is mounted on the upper longitudinal beam 710 of the frame body 700. The upper slide rail assembly 100 includes an upper mounting bracket 110 and an upper slide rail 120 connected to each other. The height of the upper slide rail 120 is lower than that of the upper longitudinal beam 710. The middle slide rail assembly 400 is mounted on the middle longitudinal beam of the frame body 700. The lower slide rail assembly 300 is mounted on the lower longitudinal beam 730 of the frame body 700.

[0042] Please combine Figure 2 The sliding rail assembly is suitable for a frame-type body 700, which has its own door opening. The sliding rail assembly consists of an upper sliding rail assembly 100, a middle sliding rail assembly 400, and a lower sliding rail assembly 300 arranged sequentially from top to bottom. The arrangement of the three sliding rail assemblies ensures the stability of the door during sliding. The upper sliding rail 120 of the upper sliding rail assembly 100 is connected to the frame-type body 700 via an upper mounting bracket 110 connected to the longitudinal beam. The height of the upper sliding rail 120 is lower than that of the upper longitudinal beam 710, allowing the upper sliding rail 120 to be directly located inside the door opening. This achieves a suspended connection of the upper sliding rail 120 to the frame-type body 700 without increasing the vertical dimensions of the sliding door, and does not affect the connection between the roof and the frame-type body 700. The structure is simple and easy to promote.

[0043] The upper slide assembly 100 is used for sliding connection with the upper slide member. In some embodiments, please refer to... Figure 5 The upper mounting bracket 110 includes a first connecting plate 111 and a first mounting plate 112 connected at an angle. The first connecting plate 111 is connected to the upper longitudinal beam 710, and the upper slide rail 120 is mounted on the first mounting plate 112. The upper longitudinal beam 710 extends along the length of the vehicle body and can be a rectangular beam or a cylindrical beam. The outermost and uppermost longitudinal beam along the width direction of the frame-type vehicle body 700 serves as the upper longitudinal beam 710 connecting the first connecting plate 111. The shapes of the first connecting plate 111 and the first mounting plate 112 can match the shape of the upper longitudinal beam 710. In some embodiments, the upper longitudinal beam 710 is a rectangular beam, and both the first connecting plate 111 and the first mounting plate 112 are flat plates. The first connecting plate 111 and the first mounting plate 112 can be a separate structure or an integral structure. In some embodiments, the first connecting plate 111 and the first mounting plate 112 are an integral structure, obtained through bending deformation, resulting in higher connection strength. The first connecting plate 111 can be connected to the bottom surface of the upper longitudinal beam 710 or to the outer surface of the upper longitudinal beam 710. In some embodiments, the first connecting plate 111 and the upper longitudinal beam 710 can be welded together or screwed together. The first connecting plate 111 and the first mounting plate 112 can be perpendicular to each other, and the included angle between the first connecting plate 111 and the first mounting plate 112 can be an acute angle or an obtuse angle.

[0044] In some embodiments, please continue to combine Figure 5 The first connecting plate 111 is connected to the bottom surface of the upper longitudinal beam 710. In some embodiments, both the upper slide rail 120 and the first mounting plate 112 are located outside the vertical projection range of the upper longitudinal beam 710, such that the first mounting plate 112 extends beyond the frame-type body 700 to increase the accommodating space enclosed by the sliding door and the frame-type body 700. In some embodiments, one end of the first connecting plate 111 is connected to the bottom surface of the upper longitudinal beam 710, and the other end extends beyond the frame-type body 700, such that the first mounting plate 112 is located outside the vertical projection range of the upper longitudinal beam 710. In some embodiments, the first connecting plate 111 and the first mounting plate 112 are perpendicular to each other.

[0045] In some embodiments, please continue to combine Figure 5 The upper slide rail 120 assembly also includes a shielding unit 200, which includes a shielding bracket 210 and a shielding member 220 connected to each other. The shielding bracket 210 is connected to the upper longitudinal beam 710, and the shielding member 220 is located on the outside of the upper slide rail 120. The shielding bracket 210 is used to install the shielding member 220, which is located on the outside of the upper slide rail 120 to shield the upper slide rail 120. This prevents the upper slide rail 120 from being exposed and affecting the aesthetics when the user opens and closes the sliding door, and also protects the upper slide rail 120 from external debris entering it. The shielding member 220 can be made of a brush and has a certain degree of elasticity. The member is located inside the upper slide rail 120 and can deform with the mounting arm that mounts the member when the sliding door moves along the length of the vehicle body, without interfering with the reciprocating movement of the mounting arm along the length of the vehicle body.

[0046] In some embodiments, please continue to combine Figure 5 The shielding bracket 210 includes a second connecting plate 211 and a second mounting plate 212 connected together. The second connecting plate 211 is connected to the upper longitudinal beam 710 and / or the first connecting plate 111. The vertical projection of the second mounting plate 212 covers the upper slide rail 120. In some embodiments, the shielding bracket 210 further includes a support plate 213 connected to the second mounting plate 212 for mounting the side panel 600, such that the second mounting plate 212 extends beyond the frame-type vehicle body 700.

[0047] In some embodiments, please continue to combine Figure 5The second mounting plate 212 is connected to the side of the upper longitudinal beam 710; the second connecting plate 211 and the support plate 213 are located at both ends of the second mounting plate 212 and are both set at an angle to the second mounting plate 212. The second connecting plate 211 is connected to the outer side of the upper longitudinal beam 710, so that the first connecting plate 111 and the second connecting plate 211 are respectively connected to the two sides of the upper longitudinal beam 710, without interfering with each other, and with high connection strength. The second connecting plate 211 and the support plate 213 are both set at an angle to the second mounting plate 212, forming a Z-shaped structure; the second connecting plate 211, the support plate 213 and the second mounting plate 212 can be a split structure, welded together. In other embodiments, the second connecting plate 211, the support plate 213 and the second mounting plate 212 are an integral structure, obtained by deforming a single plate, with high strength. The angle between the second connecting plate 211 and the support plate 213 can be acute or obtuse. In some embodiments, the support plate 213 is inclined, and the lower end of the support plate 213 is close to the outer side of the frame-type vehicle body 700, which facilitates the support of the outer side plate 600. In addition, the space above the shielding bracket 210 can be used to fix the outer side plate 600, which is a reasonable layout.

[0048] In some embodiments, please continue to combine Figure 5 The second mounting plate 212 is provided with a nest 230 for fixing the cover member 220. The nest 230 can extend along the length direction of the upper slide rail 120. The nest 230 is embeddedly connected to the cover member 220, which improves the convenience of replacing the cover member 220. The vertical dimension of the cover member 220 is larger than the dimension of the upper slide rail 120 so as to completely cover the upper slide rail 120.

[0049] In some embodiments, the upper slide 120 includes a connecting upper slide plate and two side upper slide plates, with each end of the connecting upper slide plate connected to the other two side upper slide plates. The connecting upper slide plate and the two side upper slide plates together form a space with a lower opening for the upper slide to slide. One of the side upper slide plates extends downward, and a first mounting plate 112 is connected to the downwardly extending portion of one of the side upper slide plates. The first mounting plate 112 can be screwed or welded to one of the side upper slide plates.

[0050] The sliding track assembly 300 is used for sliding connection with the sliding member. In some embodiments, please refer to... Figure 3 , Figure 7 and Figure 9The sliding track assembly 300 includes a sliding track 310 and two vertically opposite third mounting plates 330 and third connecting plates 320. Spaces for accommodating the wire harness 570 and the sliding track 310 are formed above the third mounting plate 330 and between the third mounting plate 330 and the third connecting plate 320, respectively. The third connecting plate 320 is connected to the lower longitudinal beam 730 to support the third mounting plate 330. The gap between the third mounting plate 330 and the third connecting plate 320 forms a space for accommodating the sliding track 310. The sliding track 310 can be connected to either the third mounting plate 330 or the third connecting plate 320. In some embodiments, the sliding track 310 has a lower opening for accommodating a sliding member, the top of the sliding track 310 is connected to the third mounting plate 330, and there is a space between the sliding track 310 and the third connecting plate 320 for the sliding member to extend into. In some embodiments, the top of the third mounting plate 330 may support the wiring harness 570 as a support surface for the sliding of the wiring harness 570.

[0051] In some embodiments, the lower slide rail assembly 300 further includes multiple side plates, all of which are connected to the third connecting plate 320 and the third mounting plate 330, such that the third connecting plate 320, the third mounting plate 330 and the multiple side plates form a box-shaped structure with an opening facing outwards. The box-shaped structure has high strength and simple structure, which can improve the strength of the lower slide rail assembly 300.

[0052] In some embodiments, please refer to Figure 6 The middle sliding door assembly 400 includes a connected and matched middle sliding door 410 and a support beam 420. The support beam 420 is connected to the middle longitudinal beam. In some embodiments, the middle longitudinal beam can be a longitudinal beam of the frame body 700, or it can be another longitudinal beam connected to the frame body 700. Both the support beam 420 and the middle sliding door 410 are curved beams, located outside the vertical projection range of the upper sliding door 120 and the lower sliding door 310, enabling the sliding door assembly's door body 510 to slide along the width direction and along the length direction of the vehicle body, avoiding interference between the door body 510 and the vehicle's outer side panels 600. In some embodiments, the connection method between the support beam 420 and the middle longitudinal beam can be welding or bolting, which is not limited in this application.

[0053] Based on the same technical concept as the first aspect, in the second aspect, the present invention also provides a vehicle that realizes the installation of sliding doors on a frame-type body 700.

[0054] The vehicle provided in this embodiment of the invention includes a sliding door assembly and a slide rail assembly. The sliding door assembly includes a door body 510 and an upper sliding member, a middle sliding member, and a lower sliding member connected to the door body 510. The upper sliding member is slidably engaged with the upper slide rail 120; the middle sliding member is slidably engaged with the middle slide rail 410; and the lower sliding member is slidably engaged with the lower sliding member to realize the sliding of the sliding door.

[0055] In some embodiments, please refer to Figure 8 , Figure 9 and Figure 12 The door body 510 is connected to the upper sliding member, the middle sliding member, and the lower sliding member via hinges 520. At least one hinge 520 is a split structure, comprising two hinged connecting arms 521. One of the two connecting arms 521 is connected to the door body 510, and the other is connected to one of the upper sliding member, the middle sliding member, or the lower sliding member. The split structure of the hinge 520 can be adapted to different body types by replacing the connecting arms 521 connected to the sliding members. It is suitable for both frame-type body 700 and sheet metal body, offering high versatility.

[0056] In some embodiments, please refer to Figure 10 and Figure 11 The sliding door assembly also includes a wiring harness 570 and a tank chain 560 that constrains the movement path of the wiring harness 570. The wiring harness 570 is located within the tank chain 560, with one end of the tank chain 560 slidably mounted on the top surface of the third mounting plate 330, and the other end connected to the sliding door. The tank chain 560 restricts the movement trajectory of the wiring harness 570, ensuring that the wiring harness 570 moves along a predetermined trajectory during the opening or closing of the sliding door, preventing interference between the wiring harness 570 and other structures. The wiring harness 570 ensures that the control electronics receive power when the sliding door is open or closed.

[0057] In some embodiments, there are two sliding door assemblies and two sliding components. Each side of the frame body 700 in the width direction is provided with a sliding door assembly and a sliding component. The sliding door assembly is connected to the sliding component by at least one split hinge 520.

[0058] In some embodiments, please refer to Figure 2 and Figure 4The vehicle also includes at least one integral outer side panel 600, which can be made of composite materials, such as carbon fiber outer side panel 600 prepared by a lay-up process. Compared with sheet metal parts, carbon fiber outer side panel 600 is lighter and improves the driving range of electric vehicles. The outer side panel 600 includes a main body, an upper reinforcing member, and a lower reinforcing member. The main body has a through-hole that matches the door body 510. The upper and lower reinforcing members are both connected to the main body and are located above and below the door opening, respectively. The lower reinforcing member and the main body have a clearance opening 610 to avoid the sliding track 310. The inner sides of the upper and lower reinforcing members of the sliding track 310 have protrusions that cooperate with the support plate 213. The sliding track assembly 300 and the upper sliding track assembly 100 are both located inside the outer side panel 600, the middle sliding track 410 is located outside the outer side panel 600, and the middle sliding track 410 is located on one side in the width direction of the door opening. The support beam 420 is located inside the outer side panel 600. Because the main body has a door opening that matches the door body 510, the strength of the main body above and below the door opening is low. The upper and lower reinforcing members can improve the strength above and below the door opening, and the lower reinforcing member also has a clearance function. The upper and lower reinforcing members are integrally formed with the main body.

[0059] In some embodiments, the lower reinforcement is bent at the lower edge of the doorway.

[0060] In some embodiments, the main body is provided with a central slide rail 410 clearance groove. The central slide rail 410 and the support beam 420 are located on both sides of the main body. The central slide rail 410 is located within the clearance groove, and the bottom of the clearance groove is provided with a connecting hole. The central slide rail 410 and the support beam 420 are connected by screws passing through the connecting hole, which realizes both the fixed installation of the central slide rail 410 and the connection between the main body and the frame-type vehicle body 700. The setting of the central slide rail 410 clearance groove not only improves the strength of the main body along the length of the vehicle body, but also realizes the clearance of the central slide rail 410, making the vehicle's appearance more aesthetically pleasing.

[0061] The slide assembly and vehicle provided in the embodiments of the present invention have at least the following advantages:

[0062] (1) The upper slide 120 and the frame body 700 are connected by a hoisting structure, which realizes the slide arrangement of the frame body 700 and increases the interior space.

[0063] (2) The hinge 520 with a split structure enables the sliding door to match different types of car bodies, improving versatility.

[0064] (3) A cover bracket 210 and a cover piece 220 are designed to cover the upper slide rail 120, which solves the problem of the upper slide rail 120 being exposed after the sliding door is opened, resulting in an unsightly vehicle.
