Description

Technical Field

[0001] The invention relates to the field of automobile design and manufacturing, and in particular to an electric sliding door threshold structure and an automobile provided with the threshold structure. Background Art

[0002] In the field of automobile design and manufacturing, generally speaking, a traditional sliding door threshold structure includes: a threshold side beam and a matching slide rail box assembly. In addition, a battery pack for powering electric vehicles is also provided at the bottom of the floor surface.

[0003] Please refer to Figure 1 The traditional door sill side beam is an integrated structure. In the horizontal direction, it is located on the relatively outer side of the floor surface, and in the vertical direction, it is located below the floor surface. The slide rail box assembly used to achieve the door sliding effect is arranged above the door sill side beam and below the floor surface. A part of the slide rail box assembly is fixed on the door sill side beam, and the other part extends inward and is arranged below the floor surface.

[0004] With this arrangement, since the slide rail box assembly extends from the outside to the inside and is located between the floor surface and the door sill side beam in the vertical direction, it will inevitably occupy the space below the floor surface, and the battery pack is also arranged in the space below the floor surface of the car. Therefore, the slide rail box assembly will inevitably obstruct the installation space of the battery pack, which is not conducive to the release of the installation space for the battery pack.

[0005] In addition, in the frame structure of traditional cars, the B-pillar is directly connected to the door sill side beam, so the B-pillar is connected to the bottom frame of the car through the door sill side beam. The forces in different directions generated by the car body during bumps, turns, acceleration, etc. can be transferred to the top and bottom of the car through the B-pillar, reducing the impact of these forces on the car body; in addition, if the car is hit from the side, the B-pillar can also reduce the impact of the impact force on the car body and passengers by transmitting the impact force and deforming itself. In the traditional sliding door door sill structure, the slide rail box assembly is set above the door sill side beam, which reduces the connection area between the door sill side beam and the B-pillar, so that the car body's ability to withstand various forces generated by sudden situations during driving and the impact force generated by side collisions is significantly reduced.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The present invention provides a sliding door threshold structure for an electric vehicle to solve the technical problem in the prior art that the slide rail box assembly occupies the arrangement space of the battery pack housing;

[0008] In addition, the invention solves the technical problem in the prior art that the connection area between the B-pillar and the door sill side beam is reduced because the slide rail box assembly is arranged above the door sill side beam.

[0009] The present invention provides a threshold structure of an electric sliding door, comprising a slide rail box assembly and a threshold side beam;

[0010] The threshold side beam includes a first side beam plate and a second side beam plate, the first side beam plate and the second side beam plate enclose a mounting cavity, and a through hole penetrating the first side beam plate, the second side beam plate and the mounting cavity is provided on the first side beam plate and the second side beam plate;

[0011] The slide rail box assembly is arranged in the installation cavity, and a part of it protrudes from the through hole on the second side beam plate and is located above the floor surface.

[0012] Due to the adoption of the above structure, the first side beam plate and the second side beam plate form an installation cavity, and the slide rail box assembly is fixedly installed in the installation cavity. Therefore, the slide rail box assembly does not need to consider the connection with the vehicle body too much, and can be designed into a regular strip. In addition, the slide rail box assembly is located above the floor surface in the vertical direction, and the battery pack is arranged below the floor surface. Therefore, the slide rail box assembly with a strip structure extends into the vehicle without encroaching on the space of the battery pack shell and affecting the layout of the battery pack.

[0013] In addition, since the slide rail box assembly is installed in the cavity surrounded by the first side beam plate and the second side beam plate, the B-pillar can still be directly connected to the door sill side beam, and the B-pillar can be connected to the bottom of the vehicle body through the door sill side beam 3. Therefore, during the driving process of the car, if sudden situations such as bumps, turns, acceleration, etc. occur, the forces from all directions exerted on the vehicle body can be transferred to the top and bottom of the vehicle through the B-pillar, reducing the influence of the forces in all directions on the vehicle body; similarly, if a side collision occurs, part of the collision impact force can also be transferred to the top and bottom of the vehicle through the B-pillar, and the B-pillar will also deform to absorb part of the energy, thereby reducing the damage to the vehicle body caused by the side collision and ensuring the safety of the occupants in the car.

[0014] Preferably, the slide rail box assembly comprises a U-shaped plate, and a guide rail arranged in the U-shaped plate;

[0015] The U-shaped plate of the slide rail box assembly passes through the through holes of the first side beam plate and the second side beam plate, and its closed end protrudes from the through hole of the second side beam plate; its open end is fixedly arranged on the through hole of the first side beam plate.

[0016] In the above structure, since the open end of the U-shaped plate is fixedly arranged on the through hole of the first side beam plate, and the U-shaped plate is an integral component, the through holes on the first side beam plate are connected together through the U-shaped plate, thereby reducing the influence of the first side beam plate on the door sill side beam structure due to the setting of the through holes, and improving the structural stability of the door sill side beam.

[0017] Preferably, the U-shaped plate comprises a first wall plate and a second wall plate;

[0018] The guide rail of the slide rail box assembly is fixed on the inner wall of the first wall plate, and the distance from the guide rail to the open end of the U-shaped plate is greater than the distance from the guide rail to the closed end of the U-shaped plate;

[0019] In addition, the U-shaped plate is also provided with the first roller and the second roller of the lower hinge assembly of the automobile sliding door. The first roller of the lower hinge assembly of the sliding door is arranged in the guide rail and can slide in the guide rail; the second roller of the lower hinge assembly of the sliding door is opposite to the position of the guide rail and is arranged on the inner wall of the second wall panel.

[0020] Since the first roller of the lower hinge assembly of the sliding door rolls in the fixed guide rail, the moving direction of the sliding door can be controlled by the fixed guide rail.

[0021] Preferably, the second wall panel is provided with a supporting portion extending in the direction of the first wall panel.

[0022] Due to the adoption of the above structure, the second wall panel is provided with a supporting portion extending in the direction of the first wall panel, so that the second wall panel includes two parallel panel surfaces. The above structure adopted by the second wall panel can effectively improve the rigidity of the second wall panel; at the same time, since the second roller of the lower hinge assembly of the sliding door is arranged on the above supporting portion, it not only supports the sliding door structure, but also improves the rolling accuracy of the second roller.

[0023] Preferably, the threshold structure of the present invention further includes a slide rail box patch assembly;

[0024] The slide rail box patch assembly is a U-shaped structure with one end open and the other end closed. The slide rail box patch assembly closes the portion of the slide rail box assembly protruding from the second side beam plate, and the open end of the slide rail box patch assembly is fixedly connected to the edge of the through hole on the second side beam plate.

[0025] By adopting the above structure, the slide rail box patch assembly not only closes the portion of the slide rail box assembly protruding from the second side beam plate, but also closes the through hole of the second side beam plate; in addition, since the slide rail box patch assembly is also equivalent to an integral component, the two sides of the opening of the second side beam plate are connected together through the slide rail box patch assembly, reducing the influence of the second side beam plate on the door sill side beam structure due to the provision of the through hole, thereby improving the structural stability of the door sill side beam.

[0026] Preferably, the above-mentioned sliding door threshold structure further includes a support plate;

[0027] The support plate is located in a cavity formed by the first side beam plate, the second side beam plate and the second wall plate. The lower end of the support plate is fixed at the connection between the first side beam and the second side beam; the upper end of the support plate is fixedly connected to the second wall plate.

[0028] In the above structure, in the vertical direction, the upper fixing point of the support plate is on the right side of the lower fixing point, so the part of the support plate in the cavity is inclined at a certain angle toward the vehicle body. The above connection method can not only improve the rigidity of the support plate; because the upper end of the support plate is fixed to the second wall panel, and the lower end of the support plate is indefinitely connected to the door sill side beam, the support plate will also play a certain supporting role on the slide rail box assembly.

[0029] A vehicle with any of the above electric sliding door threshold structures, the above vehicle comprising a floor surface;

[0030] The floor surface is arranged below the slide rail box supplementary plate assembly, and the floor surface is fixedly connected to the slide rail box supplementary plate assembly.

[0031] In the vertical direction, the rail box patch assembly and the rail box assembly are both arranged above the floor surface, and the battery pack shell is arranged below the floor surface, so the rail box assembly extending inward in the horizontal direction will not affect the arrangement of the battery pack shell.

[0032] Preferably, the above-mentioned automobile further comprises a seat crossbeam assembly;

[0033] The seat crossbeam assembly is arranged above the floor surface, the seat crossbeam assembly is fixedly connected to the second side beam plate, and the slide rail box patch plate assembly is located in a cavity formed by the seat crossbeam assembly and the floor surface.

[0034] With the above structure, the sliding door sill side beam structure is connected to the bottom frame of the car through the seat crossbeam assembly and the floor surface, and then the B-pillar can also be connected to the bottom frame of the car through the sill side beam structure. Therefore, during the driving of the car, if sudden situations such as bumps, turns, acceleration, etc. occur, the forces from all directions exerted on the car body can be transferred to the top and bottom of the car through the B-pillar, reducing the impact of the forces in all directions on the car body; similarly, if a side collision occurs, part of the collision impact force can also be transferred to the top and bottom of the car through the B-pillar, thereby reducing the damage to the car body caused by the side collision and ensuring the safety of the occupants in the car.

[0035] Preferably, the above-mentioned automobile further comprises a battery pack housing and a pressed part;

[0036] The battery pack shell is arranged below the floor surface, and the pressed piece is on one side of the opening of the battery pack shell. The pressed piece is fixedly connected to the battery pack shell to form a cavity for arranging the battery pack.

[0037] The pressed part also includes a flange edge, and the flange edge of the pressed part is fixed to the second side beam plate by bolts.

[0038] The pressed part is fixedly connected to the battery pack shell, that is, the pressed part is connected to the bottom frame of the car, and the flange edge of the pressed part is arranged under the second side beam plate and fixed by bolts, so that the flange edge of the pressed part can support the second side beam plate.

[0039] Preferably, a support structure is provided inside the above-mentioned pressed part;

[0040] The flange edge is in a crescent-shaped structure; a straight side of the flange edge contacts the second side beam plate, and an inclined side opposite to the straight side is inclined in a direction away from the second side beam plate.

[0041] A supporting structure is arranged inside the pressed part to improve the rigidity and structural stability of the pressed part; the contact between the straight side of the above-mentioned flange and the second side beam plate does not refer to specific contact, but refers to the flange being fixedly connected to the second side beam plate by bolts, and the distance from the straight side of the flange to the second side beam plate is smaller than the distance from the inclined side of the flange to the second side beam plate; the above-mentioned crescent-shaped structure means that the upper wall of the flange is a straight side in the horizontal direction, the left wall is a straight side in the vertical direction, and the lower wall is composed of a horizontal straight side and a folded edge deviating from the upper wall, and the shape is similar to that of a horizontal crescent; the inclined structure arranged on the lower wall of the flange can improve the rigidity of the flange.

[0042] In summary, in the sliding door threshold structure of the present invention, the slide rail box assembly passes through the through hole of the threshold side beam, so that the protruding portion of the slide rail box assembly is located above the floor surface, the protruding portion of the slide rail box assembly is closed by the slide rail box supplementary plate assembly, and the sliding door threshold structure is fixed to the vehicle body through the seat crossbeam assembly, the floor surface and the pressed part;

[0043] In this way, the slide rail box assembly is located above the floor surface in the vertical direction, and the battery pack shell is arranged below the floor surface, so that the slide rail box assembly extends inward in the horizontal direction and will not occupy the position of the battery pack shell, thereby affecting the layout of the battery pack.

[0044] In addition, since the slide rail box assembly is installed in the cavity of the sill side beam, it will not affect the connection relationship between the B-pillar and the sill side beam. Therefore, the B-pillar can still be directly connected to the sill side beam, and the B-pillar can be connected to the bottom of the vehicle body through the sill side beam 3. Therefore, during the driving process of the car, if sudden situations such as bumps, turns, acceleration, etc. occur, the forces from all directions exerted on the vehicle body can be transferred to the top and bottom of the vehicle through the B-pillar, reducing the impact of the forces in all directions on the vehicle body; similarly, if a side collision occurs, part of the collision impact force can also be transferred to the top and bottom of the vehicle through the B-pillar, thereby reducing the damage to the vehicle body caused by the side collision and ensuring the safety of the occupants in the vehicle.
