Description

Technical Field

[0001] This application relates to the field of automobile doors, and in particular to a door opening mechanism and a vehicle. Background Technology

[0002] With the development of technology and the times, the scissor door design of automobiles can be opened and closed by scissor motion, allowing the door to be opened in narrow spaces. Compared with the traditional swing door opening action, it is more stylish and is a design that combines practicality and aesthetics.

[0003] In existing technologies, scissor doors often use gas springs to assist in opening and closing. The assist structure is relatively complex, which can easily lead to quality problems. It is also difficult to pinpoint the location of the problem, making maintenance challenging. Summary of the Invention

[0004] This application provides a door opening mechanism and a vehicle, which uses a traditional mechanical structure to support the opening and closing of the scissor door, thus avoiding maintenance difficulties when quality problems occur.

[0005] To address the aforementioned technical problems, this application proposes a vehicle door opening mechanism, mounted on a vehicle body, for switching the vehicle door between a first state and a second state. The mechanism includes a fixing member fixed to the vehicle body, comprising a connecting portion and a locking portion. The centerline of the connecting portion is parallel to the width direction of the vehicle body. A torsion spring, including a first fixing foot and a second fixing foot, is fitted onto the connecting portion. The first fixing foot is fixed to the vehicle body, and the second fixing foot is fixedly connected to the vehicle door. When the vehicle door switches from the first state to the second state, the door is pushed outwards from the vehicle body, and under the action of the torsion spring, the door moves around the centerline of the connecting portion until it stops at the locking portion to remain in the second state.

[0006] Specifically, it also includes a limiting member, which is movably connected to the fixing member and can rotate around the connecting portion. The limiting member is fixedly connected to the second fixing foot or the vehicle door. The limiting member is provided with a stop portion, which rotates with the vehicle door to engage with the locking portion when the vehicle door switches from the first state to the second state.

[0007] Specifically, the locking part includes a stop surface, and the angle between the stop part and the stop surface is 30 degrees to 180 degrees.

[0008] Specifically, the locking part is provided with a slot, and the stop part is engaged in the slot.

[0009] Specifically, it also includes an elastic element and a stop block disposed on the vehicle body. The vehicle body has mounting holes, and the elastic element and part of the stop block are disposed within the mounting holes, with the elastic element elastically connecting the mounting hole and the stop block. One end of the stop block exposed in the mounting hole has a beveled or arc-shaped surface.

[0010] Specifically, the connecting portion is provided with a pivot hole, and the limiting member includes a pivot shaft, which is rotatably installed within the pivot hole. The centerline of the connecting portion is collinear with the centerline of the pivot hole.

[0011] Specifically, the fixing member further includes a fixing plate, which is fixed to the vehicle body. The connecting portion protrudes and connects to the fixing plate, and the connecting portion includes an arc-shaped outer side surface. The limiting member includes a plate body and a side plate connecting to the plate body. The pivot shaft is formed by the plate body protruding from it. The side plate surrounds the outer side surface, and the inner side surface of the side plate is an arc surface corresponding to the outer side surface.

[0012] Specifically, the vehicle body includes a side panel, and a fixing plate is fixed to the side panel. The fixing plate is semi-circular, and the locking portion is formed by extending the side wall of the fixing plate near the first fixing foot in a direction perpendicular to the side panel. The pivot hole penetrates the fixing plate. The plate body is located between the fixing plate and the side panel, and the stop portion is the side end face of the side plate away from the second fixing foot.

[0013] Specifically, the plate is located at the top of the connecting portion away from the fixing plate. One end of the fixing plate protrudes away from the side panel to form a stop surface, which is the side end face of the side panel away from the second fixing foot.

[0014] Specifically, one end of the fixing plate has a positioning block protruding in a direction away from the side panel, and the first fixing foot elastically stops on the positioning block.

[0015] Specifically, the vehicle door includes a mounting plate, the mounting plate includes a connecting plate and a limiting plate, the limiting plate is perpendicular to the connecting plate, the connecting plate is fixed to the vehicle door, and the second fixing foot abuts against the limiting plate.

[0016] Another technical solution proposed in this application is to provide a vehicle including any of the door opening mechanisms described above.

[0017] The beneficial effects of this application are as follows: Compared with existing car door opening mechanisms, the car door opening mechanism proposed in this application is installed on the vehicle body and used to switch the car door between a first state and a second state. The car door opening mechanism includes a fixing member and a torsion spring. The fixing member is fixed to the vehicle body and includes a connecting part and a locking part. The center line of the connecting part is parallel to the width direction of the vehicle body. The car door rotates around the connecting part, realizing that the car door opens in the opposite direction to the direction of gravity, enabling it to open in narrow spaces. The torsion spring includes a first fixed foot and a second fixed foot. The torsion spring is fitted onto the connecting part. The first fixed foot is fixed to the vehicle body, and the second fixed foot is fixedly connected to the car door. By changing the relative position of the first and second fixed feet of the torsion spring, the car door can be kept in either the first state or the second state. When the car door switches from the first state to the second state, the car door is pushed out of the vehicle body, and the car door moves around the center line of the connecting part under the action of the torsion spring until it stops at the locking part to maintain the second state. The torsion force of the torsion spring allows the car door to be kept in a stable state, further improving the stability of the car door opening mechanism. Attached Figure Description

Obviously, the drawings described below are merely some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort, wherein:

[0019] Figure 1 This is a schematic diagram of the structure of one embodiment of the door opening mechanism provided in this application;

[0020] Figure 2 yes Figure 1 The diagram shows the connection structure between the door opening mechanism and part of the door. Detailed Implementation

[0021] The technical solutions of 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. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0023] One aspect of this application provides a vehicle, please refer to... Figure 2 , Figure 2 yes Figure 1 The diagram shows the connection structure between the door opening mechanism and part of the door. The vehicle includes a door opening mechanism for connecting the vehicle body and the door 5, and for switching the door between a first state and a second state. Through this door 5 opening mechanism, the door 5 can be opened in the opposite direction of gravity, so that the door 5 can be opened in narrow places while maintaining a relatively aesthetically pleasing appearance.

[0024] Another aspect of this application provides a door opening mechanism, please refer to... Figure 1 , Figure 1 This is a schematic diagram of an embodiment of the door opening mechanism provided in this application. Specifically, the door opening mechanism includes a fixing member 1 and a torsion spring 2. The fixing member 1 is fixed to the vehicle body and includes a connecting part 11 and a locking part 12. The center line of the connecting part 11 is parallel to the width direction of the vehicle body. The door 5 rotates around the connecting part 11, thereby opening the door 5 in the direction opposite to the direction of gravity, allowing it to be opened in narrow spaces. The torsion spring 2 includes a first fixing foot 21 and a second fixing foot 22. The torsion spring 2 is fitted onto the connecting part 11. The first fixing foot 21 is fixed to the vehicle body, and the second fixing foot 22 is fixedly connected to the door 5. By changing the relative position of the first fixing foot 21 and the second fixing foot 22 of the torsion spring 2, the door 5 can be kept in either a first state or a second state. The first state is the closed state of the car door, and the second state is the open state of the car door. When the car door 5 switches from the first state to the second state, the car door 5 is pushed out of the car body, and the car door 5 moves around the center line of the connecting part 11 under the action of the torsion spring 2 until it stops at the locking part 12 to maintain the second state, thus completing the opening of the car door 5. The torsion force of the torsion spring 2 enables the car door 5 to be kept in a stable state, further improving the stability of the car door opening mechanism.

[0025] In some embodiments, the door opening mechanism further includes a limiting member 3, which is movably connected to the fixing member 1 and can rotate around the connecting part 11. The limiting member 3 is fixedly connected to the second fixing foot 22 or the door 5. It is used to control the door 5 and keep it stable in the second state when the door 5 moves from the first state to the second state, so as to prevent the door 5 from exceeding the required turning angle when it is turned over, which would cause the center of gravity of the door to become unbalanced and thus cause the door to fall, creating a safety hazard. The limiting member 3 is provided with a stop part 31. When the door 5 switches from the first state to the second state, the stop part 31 rotates with the door 5 to lock the locking part 12, so as to prevent the turning angle of the door from being too large when it is turned over, which would damage the torsion spring 2, affect the torque force of the torsion spring 2, and affect the service life of the door opening mechanism.

[0026] To prevent damage to fastener 1 due to excessive kinetic energy during the door's rollover, please continue to refer to... Figure 1 In some embodiments, the locking part 12 includes a stop surface 120, which is used to abut against the stop part 31 and fully contact the stop part 31 to prevent the contact area between the limiting member 3 and the fixing member 1 from being too small when the door 5 is flipped upward, resulting in a large impact force of the limiting member 3 on the fixing position of the fixing member 1, which could lead to the fixing member 1 falling off. Specifically, the included angle between the stop part 31 and the stop surface 120 is 30 degrees to 180 degrees, wherein the included angle between the stop part 31 and the stop surface 120 can be 30 degrees, 50 degrees, 70 degrees, 90 degrees, 110 degrees, 130 degrees, 150 degrees, 180 degrees, etc. When the door 5 is in the first state, the included angle between the stop part 31 and the stop surface 120 is 180 degrees. At this time, the door 5 is kept in the closed state, the door 5 is fixed to the body, and the gravity of the door 5 resists the torsional force of the torsion spring 2, keeping the door 5 in a stable closed state; when When the door 5 is in the second state, the angle between the stop part 31 and the stop surface 120 can be set according to the needs of different vehicles. Optimally, the angle can be 30 degrees to 50 degrees. Specifically, it can be 30 degrees, 35 degrees, 40 degrees, 45 degrees or 50 degrees, etc., to ensure that the door 5 is aesthetically pleasing when opened and to meet the actual needs of the driver. At this time, the door 5 is kept open, the stop part 31 abuts against the stop surface 120, and the torsional force of the torsion spring 2 resists the gravity of the door 5, so that the door 5 is kept in a stable open state.

[0027] Furthermore, in some vehicle models, the door 5 is kept in the second state solely by the torsion spring 2 and the limiting member 3. This may lead to instability of the door 5 in some situations, causing safety hazards. To ensure that the door 5 remains open for an extended period, the locking part 12 is provided with a slot (not shown), and the stop part 31 is engaged with the slot. When the door is in the second state, the limiting member 3 not only limits the rotation angle of the door 5 but also secures it to the fixing member 1, ensuring that the door 5 remains stably in the second state.

[0028] In other embodiments, the door opening mechanism further includes an elastic element (not shown) and a stop block (not shown) disposed on the vehicle body. The vehicle body has mounting holes (not shown). The elastic element and part of the stop block are disposed within the mounting holes, and the elastic element elastically connects the mounting holes and the stop block. The stop block can be completely accommodated in the mounting hole under the action of the stop part 31 and the elastic element, and the stop part 31 is fixed to the fixing member 1, ensuring that the door 5 can stably remain in the second state after being flipped. One end of the stop block exposed in the mounting hole has a bevel or arc-shaped surface, further ensuring that when the limiting member 3 approaches the fixing member 1 as the door 5 flips, the stop block abuts against the fixing member 1. The fixing member 1 pushes the stop block into the mounting hole along the bevel or arc-shaped surface, compressing the elastic element. When the door 5 needs to return to the first state, the elastic element recovers its deformation, and part of the stop block disengages from the mounting hole, pushing the limiting member 3 and the second fixing foot 22 of the torsion spring 2 away from the vehicle body, providing an initial force for the door 5 to return to the first state, thus restoring the door 5 to the first state.

[0029] Please continue to refer to the reference. Figure 1 and Figure 2 In some embodiments, the connecting portion 11 is provided with a pivot hole 111, and the limiting member 3 includes a pivot shaft 32. The pivot shaft 32 is rotatably installed in the pivot hole 111 to prevent the pivot shaft 32 from directly contacting the limiting member 3 or other structures, which would cause wear on the surface of the pivot shaft 32, thereby affecting the smoothness of the door 5's rotation and the service life of the door opening mechanism. Furthermore, the centerline of the connecting portion 11 is collinear with the centerline of the pivot hole 111, further ensuring that the door 5 does not generate any additional movement tendency with the connecting portion 11 when rotating along the pivot shaft 32, reducing the additional force on the torsion spring 2 and enhancing the service life of the entire door opening mechanism.

[0030] Furthermore, to enhance the stability of the entire door opening mechanism's fixation to the vehicle body, in some embodiments, the fixing member 1 further includes a fixing plate 13. The fixing plate 13 is fixed to the vehicle body, increasing the contact area between the fixing member 1 and the vehicle body. This prevents excessive torsional force between the door opening mechanism and the vehicle body when the door 5 rotates around the pivot axis 32, which could cause the door opening mechanism to detach from the vehicle body and thus create a safety hazard. The connecting part 11 protrudes to connect the fixing plate 13, preventing the torsion spring 2 and the limiting member 3 from directly contacting the connection point between the fixing member 1 and the vehicle body, thereby affecting the stability of the door opening mechanism. Furthermore, the connecting part 11 includes an arc-shaped outer surface 110, the limiting member 3 includes a plate 33 and a side plate 34 connecting the plate 33, the pivot shaft 32 is formed by protrusion of the plate 33, the side plate 34 surrounds the outer surface 110, the two ends of the side plate 34 can respectively abut against the first fixed foot 21 and the second fixed foot 22, and the inner surface of the side plate 34 (not shown) is an arc surface corresponding to the outer surface 110, ensuring that the limiting member 3 can move smoothly on the connecting part 11, and realize the functions of limiting and fixing.

[0031] In some embodiments, the vehicle body includes a side panel (not shown), and a fixing plate 13 is fixed to the side panel, thereby fixing the fastener 1 to the vehicle body. The fixing plate 13 is semi-circular and concentrically arranged with the torsion spring 2 to prevent relative obstruction between the second fixing foot 22 and the fixing plate 13 when the torsion spring 2 is torn, which would affect the direction of the torsional force of the torsion spring 2 and prevent the door 5 from opening normally, thus affecting the usability of the door opening mechanism. The locking part 12 is formed by extending the side wall of the fixing plate 13 near the first fixing foot 21 in a direction perpendicular to the side panel, and is used to abut against the first fixing foot 21 when the torsion spring 2 is torn. This prevents the first fixing foot 21 from tending to rotate toward the second fixing foot 22 and move toward the first fixing foot 21 when the torsion spring 2 is torn, so that the torsional force of the torsion spring 2 cannot be fully used to resist the weight of the door 5, thereby affecting the normal operation of the door opening mechanism and even affecting the normal opening of the door 5. The pivot hole 111 passes through the fixed plate 13, and the pivot shaft 32 is housed in the pivot hole 111, which drives the limit member 3 to rotate as the torsion spring 2 moves. The plate 33 is located between the fixed plate 13 and the side plate. The stop part 31 is the side end face of the side plate 34 away from the second fixed foot 22. At this time, when the limit member 3 rotates with the torsion spring 2, the stop part 31 can abut against the locking part 12, preventing the stop part 31 from continuing to move towards the first fixed foot 21, so that the door 5 can be stably maintained in the second state when changing from the first state to the second state, that is, ensuring the stable opening state of the door 5.

[0032] In other embodiments, the plate 33 is located at the top of the connecting portion 11 away from the fixing plate 13. One end of the fixing plate 13 protrudes away from the side panel and forms a stop surface 120. The stop surface 120 is the side end face of the side panel away from the second fixing foot 22. The stop portion 31 abuts against the stop surface 120, preventing the stop portion 31 from continuing to move towards the first fixing foot 21, ensuring that the door 5 can be stably maintained in the second state when changing from the first state to the second state, that is, ensuring that the door 5 is stably open.

[0033] Furthermore, a positioning block (not shown) is formed on one end of the fixing plate 13 in a direction away from the side panel. The first fixing foot 21 is elastically stopped on the positioning block. When the limiting member 3 moves with the torsion spring 2 and moves closer to the first fixing foot 21, the stop part 31 moves to abut against the other end of the positioning block and is elastically fixed to the positioning block. This further ensures that when the limiting member 3 moves closer to the first fixing foot 21 with the torsion spring 2, the stop part 31 can be stably fixed to the fixing member 1 and maintain the stability of the second state of the door 5.

[0034] In other embodiments, please continue to refer to Figure 1 Two plates 33 can be provided, respectively set at both ends of the side plate 34. When the torsion spring 2 moves, the limiting member 3 can completely abut against the locking part 12 of the fixing member 1. This avoids the excessive torque generated by the torsion spring 2 when the door 5 changes to the second state, which would cause the stop part 31 to exert excessive force on the locking part 12, resulting in damage or displacement of the fixing member 1 and thus affecting the normal use of the door opening mechanism.

[0035] In some embodiments, the door 5 includes a mounting plate 4, so that when the door opening structure is installed on the door 5, it does not directly contact the door 5, thus avoiding damage to the door 5 when the door opening structure is damaged, resulting in unnecessary maintenance costs. The mounting plate 4 includes a connecting plate 41 and a limiting plate 42. The limiting plate 42 is set perpendicular to the connecting plate 41. The connecting plate 41 is fixed to the door 5, and the second fixing foot 22 abuts against the limiting plate 42. This prevents the torsion force from having a component force toward the limiting plate 42 when the torsion spring 2 is torn, and prevents the second fixing foot 22 from detaching from the mounting plate 4 when it moves, which would significantly affect the structural integrity of the door opening structure and thus affect the normal operation of the entire door opening structure.
