[0019] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.
[0020] In this disclosure, unless otherwise indicated, directional terms such as "upper," "lower," "top," and "bottom" generally refer to the upper, lower, top, and bottom positions of the corresponding component in the direction of gravity when in use. "Inside" and "outside" refer to the inside and outside relative to the outline of the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not convey order or importance. Furthermore, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same element.
[0021] In order to achieve the above-mentioned purpose, the present disclosure provides a scissor door hinge, which is used to be set at the hinge of the vehicle body 11 and the vehicle door 10. The scissor door hinge includes: a vehicle body mounting base 1, which is used to be connected to the side wall of the vehicle body 11; a vehicle door mounting base 2, which is used to be connected to the vehicle door 10; a drive shaft 3, which is rotatably connected to the vehicle body mounting base 1 and is vertically arranged to the vehicle body mounting base 1; a drive block 4, which is fixedly connected to the drive shaft 3; a transmission shaft group 5, through which the vehicle door mounting base 2 is rotatably connected to the drive block 4; and a linkage assembly 6, through which the drive shaft 3 drives the drive shaft group 5 to rotate, thereby driving the vehicle door mounting base 2 to rotate toward or away from the vehicle body mounting base 1 while rotating synchronously with the drive block 4.
[0022] Through the above technical solution, the body mounting base 1 is installed on the body 11, the drive shaft 3 is arranged perpendicular to the body mounting base 1 and connected to the drive device, for example, the drive device is a motor, the body mounting base 1 is arranged along the X direction, and the drive shaft 3 extends along the Y direction, such as Figure 1 As shown, the rotation of the drive shaft 3 drives the drive block 4 to rotate synchronously around the Y direction, and the door mounting seat 2 is connected to the drive block 4 through the transmission shaft group 5. When the drive shaft 3 rotates, the transmission shaft group 5 is driven to rotate through the linkage component 6, thereby driving the door 10 to rotate in the direction close to or away from the vehicle body mounting seat 1. When the door 10 is opened, it moves upward and opens outward while moving upward. The two steps move simultaneously, reducing the opening steps of the door 10, and only one driving device is needed to realize the opening and closing function of the scissor door. For example, the upward opening angle of the door 10 is 70°-90°.
[0023] As an optional implementation, Figure 1-2As shown, the linkage assembly 6 includes an arcuate guide rail 61 and a first linkage rod 62. One end of the first linkage rod 62 is connected to the transmission shaft group 5, and the other end is slidingly connected to the arcuate guide rail 61 through a ball bearing. The arcuate guide rail 61 is arranged on the vehicle body mounting seat 1 and extends along the movement trajectory of the first linkage rod 62. There is an angle between the side of the arcuate guide rail 61 in contact with the first linkage rod 62 and the vehicle body mounting seat 1. The rotation of the drive shaft 3 drives the first linkage rod 62 to move along the arcuate guide rail 61. Since there is an angle between the arcuate guide rail 61 and the vehicle body mounting seat 1, the first linkage rod 62 rotates in the Y direction and moves in the extension direction of the Y direction at the same time, thereby driving the transmission shaft group 5 to rotate, and then driving the door mounting seat 2 and the vehicle door 10 to rotate.
[0024] Alternatively, as Figure 1-3 As shown, the arcuate guide rail 61 has a starting position and an ending position above the starting position. The first linkage rod 62 is in a horizontal state when it is in the starting position. The side of the arcuate guide rail 61 that contacts the first linkage rod 62 gradually tilts toward the side close to the vehicle body mounting seat 1 from the starting position to the ending position. The starting position is the position where the vehicle door 10 is closed. The movement from the starting position to the ending position is the process of opening the vehicle door 10. During the process of opening the vehicle door 10, the first linkage rod 62 gradually moves toward the side close to the vehicle body mounting seat 1, thereby driving the transmission shaft group 5 to rotate.
[0025] In addition, if Figure 1 and Figure 3 As shown, the linkage assembly 6 also includes a second linkage rod 63 and an elastic member 64. Support legs 8 are provided at both ends of the arcuate guide rail 61 to ensure a gap between the arcuate guide rail 61 and the vehicle body mounting seat 1. One end of the second linkage rod 63 is connected to the drive shaft 3, and the other end passes through the gap and is connected to the end of the first linkage rod 62 through the elastic member 64. For example, the elastic member 64 is a spring. When in the starting position, the spring is in a stretched state. The spring is used to provide a preload force. The second linkage rod 63 rotates synchronously with the first linkage rod 62 around the Y direction. While rotating, the spring gradually contracts. In this way, the first linkage rod 62 can always be in contact with the arcuate guide rail 61 through the spring to prevent the first linkage rod 62 from derailing and not always fitting with the arcuate guide rail 61.
[0026] Optionally, when the first linkage rod 62 moves from the starting position to the end position along the opening direction of the door 10, the door mounting seat 2 rotates toward the vehicle body mounting seat 1, because the scissor door hinge is provided at the connection between the door 10 and the vehicle body 11. Figure 6 As shown, when the door mounting base 2 rotates toward the direction close to the vehicle body 11 , the open side of the door 10 will move outward, thereby causing the door 10 to open outward.
[0027] Among them, Figure 1-2As shown, the transmission shaft group 5 includes a first transmission shaft 51, a second transmission shaft 52 and a transmission assembly 9. The first transmission shaft 51 is connected to the second transmission shaft 52 through the transmission assembly 9. The first transmission shaft 51 is connected to the first linkage rod 62, and the second transmission shaft 52 is connected to the door mounting seat 2. The first transmission shaft 51 and the second transmission shaft 52 are both arranged perpendicular to the drive shaft 3, that is, they are arranged parallel to the vehicle body mounting seat 1 to drive the door mounting seat 2 to move toward and away from the vehicle body 11. The first transmission shaft 51 and the second transmission shaft 52 are respectively connected to the first linkage rod 62 and the door mounting seat 2, and are connected through the transmission assembly 9. The first linkage rod 62 drives the first transmission shaft 51 to rotate, and the first transmission shaft 51 drives the second transmission shaft 52 to rotate through the transmission assembly 9, thereby driving the door mounting seat 2 and the vehicle door 10 to rotate.
[0028] In addition, if Figure 4 As shown, the transmission assembly 9 includes a first shaft gear 91 and a second shaft gear 92. The first shaft gear 91 is sleeved on the first transmission shaft 51 and is fixedly connected to the first transmission shaft 51. The second shaft gear 92 is sleeved on the second transmission shaft 52 and is fixedly connected to the second transmission shaft 52. The first shaft gear 91 is engaged with the second shaft gear 92. The first transmission shaft 51 and the second transmission shaft 52 are connected through the first shaft gear 91 and the second shaft gear 92, which are used to change the movement direction of the second transmission shaft 52. Figure 4 As shown, when the vehicle door 10 is opened, the first transmission shaft 51 rotates counterclockwise and the second transmission shaft 52 rotates clockwise, thereby driving the door mounting base 2 to rotate toward the vehicle body mounting base 1. Of course, in other embodiments, the first shaft gear 91 and the second shaft gear 92 can also be connected by a belt, chain, etc. to rotate in the same direction. In this case, the angle between the arc-shaped guide rail 61 and the vehicle body mounting base 1 only needs to be tilted in the opposite direction to ensure that the door mounting base 2 rotates toward the vehicle body mounting base 1 when the vehicle door 10 is opened.
[0029] Alternatively, as Figure 1-2 As shown, one end of the second transmission shaft 52 extends beyond the drive block 4 and is connected to the door mounting base 2 via bolts. This arrangement facilitates the disassembly and installation of the door 10. If the second transmission shaft 52 does not extend beyond the drive block 4, the drive block 4 will be obscured, making it difficult to disassemble and install the bolts.
[0030] As an optional implementation, Figure 2-3 and Figure 5As shown, the scissor door hinge also includes a limit member 7, which is arranged on the vehicle body mounting seat 1, and the limit member 7 contacts the drive block 4 when the drive block 4 is in the starting position and the ending position. For example, the limit member 7 is a limit block, and the drive block 4 is rectangular. The limit member 7 is arranged on the extension line of the center line of the arc guide rail 61 and contacts the side of the drive block 4 away from the first linkage rod 62. The limit member 7 limits the drive block 4 to prevent the car door 10 from hitting the side of the car body 11 due to inertia. When the drive block 4 is in the starting position, it resists the drive block 4 to prevent the car door 10 from hitting the car body 11 when closing. When the drive block 4 rotates to the ending position, it also contacts the limit member 7 to prevent the car door 10 from hitting the car body 11 when opening.
[0031] As an optional embodiment, the angle is 5°-15°, that is, the angle at which the door 10 opens outward is 5°-15°, for example, it can be 5°, 10° or 15°, to prevent the door 10 from scratching the car body 11 during the opening process, while leaving more space for passengers to enter and exit.
[0032] like Figure 6 As shown, another object of the present disclosure is to provide a vehicle, comprising: a vehicle door 10; a vehicle body 11; and the above-mentioned scissor door hinge, wherein the vehicle door 10 is hinged to the vehicle body 11 through the scissor door hinge, and the vehicle door 10 moves upward when opened, and opens outward while moving upward, and the two steps move simultaneously, thereby reducing the opening steps of the vehicle door 10, and only one driving device is required to realize the opening and closing function of the scissor door.
[0033] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.
[0034] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0035] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
