[0024] The invention discloses a side door opening mechanism, which reduces the width of the side door, thereby reducing the width of the vehicle body and improving the vehicle's passability.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1 and Figure 3 The present invention provides a side door opening mechanism 100, comprising a mounting plate 3, to which a first adapter bracket 15 is rotatably connected via a handle shaft. The first adapter bracket 15 is linked to a handle mounting bracket 14, which is fixedly connected to an inward opening handle 11. Both the handle mounting bracket 14 and the inward opening handle 11 are rotatably connected to the handle shaft, which is arranged perpendicular to the longitudinal plane of the vehicle body. The first adapter bracket 15 is connected to the door lock 5 via a transmission structure. Figure 1 and Figure 2 The dotted lines in the figure are auxiliary connection lines, that is, the components on each dotted line represent the components connected together, which facilitates the understanding of the exploded view. Figure 3 for Figure 1 and Figure 2 Schematic diagram of the structure after the various parts of the structure are assembled.

[0027] The mounting plate 3 is fixedly connected to the door frame 4, and both the mounting plate 3 and the door frame 4 are made of metal. The handle shaft includes a pin 2 fixedly connected to the mounting plate 3, and the tail end face of the pin 2 is provided with a first threaded hole in the axial direction. The first adapter bracket 15 and the handle mounting bracket 14 are sleeved on the pin 2. The first adapter bracket 15, the handle mounting bracket 14 and the inward opening handle 11 are positioned by a first bolt 12 connected to the first threaded hole. The handle mounting bracket 14 is connected to the side of the inward opening handle 11 near the mounting plate 3 by a second bolt 16. The door lock 5 is fixedly connected to the door frame 4. The first adapter bracket 15 and the handle mounting bracket 14 are both plate-like structures arranged parallel to the longitudinal plane of the vehicle body.

[0028] The side door opening mechanism 100 of the present invention is achieved by arranging the handle shaft perpendicularly to the longitudinal plane of the vehicle body, and simultaneously arranging a handle mounting bracket 14, a first adapter bracket 15 and an inner opening handle 11 that are rotatably connected to the handle shaft. The handle mounting bracket 14, the first adapter bracket 15 and the inner opening handle 11 are all plate-like structures arranged parallel to the longitudinal plane of the vehicle body, thereby reducing the required width of each component and the width of the entire side door opening mechanism 100, thereby reducing the width of the side door, and further reducing the width of the vehicle body, thereby improving the vehicle's passability.

[0029] Specifically, the transmission structure includes a second adapter bracket 21, one end of which is rotatably connected to the mounting plate 3, and the other end is rotatably connected to the first adapter bracket 15 through the first pull rod 18. The second adapter bracket 21 is slidably connected to the connecting bracket 8. The connecting bracket 8 is connected to the door lock 5 through the second pull rod 6. A first nut 20 is fixedly connected to the mounting plate 3, and a positioning ring is provided on the end face of the first nut 20. The second adapter bracket 21 is rotatably connected to the mounting plate 3 through a third bolt 9 connected to the first nut 20. One end of the first pull rod 18 is connected to the first adapter bracket 15 through the first pull rod sleeve 17, and the other end is connected to the second adapter bracket 21 through the first pull rod sleeve 17. The second pull rod 6 can open the door lock 5 as the connecting bracket 8 is pulled. The third bolt 9 is a step bolt.

[0030] Further, such as Figure 4 As shown, the lower end of the connecting bracket 8 is provided with a vertically arranged elongated connecting hole 83, which is connected to the handle mounting base 1 via a connecting member. The handle mounting base 1 is fixedly connected to the mounting plate 3. The connecting member includes a sixth bolt 13 and a second screw sleeve 10 for use. The second screw sleeve 10 is a stepped screw sleeve.

[0031] To facilitate automatic return and locking of door lock 5 after unlocking, the upper end of connecting bracket 8 is connected to one end of a return spring 7, the other end of which is connected to door frame 4. Specifically, a positioning hook is fixedly connected to door frame 4. This positioning hook is connected to a first hook at the upper end of return spring 7, and a second hook at the lower end of return spring 7 is connected to a hanging hole 81 at the upper end of connecting bracket 8. Return spring 7 is connected between connecting bracket 8 and door frame 4, so that connecting bracket 8 is in its uppermost position in its natural state, at which time return spring 7 is in its natural state.

[0032] like Figure 5 and Figure 6 As shown, a first ring sleeve 151 is provided around the through hole where the first adapter bracket 15 is connected to the handle shaft. A second ring sleeve 141 is provided around the through hole where the handle mounting bracket 14 is connected to the handle shaft, and the first ring sleeve 151 and the second ring sleeve 141 are arranged opposite to each other. Corresponding interlocking structures are provided on the oppositely arranged end surfaces of the first ring sleeve 151 and the second ring sleeve 141. The interlocking structure on the first ring sleeve 151 is a first latching groove 152, and the interlocking structure on the second ring sleeve 141 is a first latching tooth 142. The first groove 152 and the first latching tooth 142 are arranged correspondingly, thereby transmitting the rotation of the handle mounting bracket 14 to the first adapter bracket 15. In other embodiments, the interlocking structure may also be a rotation transmission structure commonly used by other persons skilled in the art, which is not limited here.

[0033] In one embodiment, referring to Figure 7 The second adapter bracket 21 is an L-shaped plate, and the corner end of the L-shaped plate is rotatably connected to the mounting plate 3 by a fourth bolt passing through the connecting through hole 212. The L-shaped plate includes two vertically arranged plate-like structures, one end away from the corner end is rotatably connected to the first pull rod 18, and the other end is provided with a limited long hole 211, and the limited long hole 211 is used for sliding connection with the connecting bracket 8. The L-shaped plate is connected to the connecting bracket 8 by a fifth bolt 19 passing through the limited long hole 211. When the L-shaped plate rotates around the fourth bolt connected to the corner end, the fifth bolt 19 can drive the connecting bracket 8 to move along the limited long hole 211. The fifth bolt 19 is a step bolt.

[0034] In order to facilitate the control of the upper and lower limits of the movement of the connecting bracket 8, a limiting bent plate 82 is provided on the surface of the connecting bracket 8 close to the mounting plate 3. The limiting bent plate 82 is slidably connected in the limiting groove of the handle mounting seat 1, thereby limiting the displacement limit of the connecting bracket 8.

[0035] During use, when the inner opening handle 11 is pressed downward, the handle mounting bracket 14 rotates around the pin shaft 2 at the same time. The rotation of the handle mounting bracket 14 drives the first adapter bracket 15 to rotate. The rotation of the first adapter bracket 15 drives the first pull rod 18 to move. The movement of the first pull rod 18 drives the second adapter bracket 21 to rotate. The second adapter bracket 21 rotates around the third bolt 9. The rotation of the second adapter bracket 21 drives the connecting bracket 8 to move downward. The connecting bracket 8 is connected to the second pull rod 6 through the second pull rod sleeve. When the connecting bracket 8 moves downward, it drives the second pull rod 6 downward, thereby opening the door lock 5.
