[0039] The technical solutions of the present invention will be further described in detail below through embodiments in conjunction with the drawings. The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined with respect to the structures shown in the respective drawings. The terms "inside" and "outside" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may therefore change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0040] The present application provides an external door opening device, including: a base 1, a locking mechanism 2, a safety release mechanism, a mechanical release mechanism 5, and a door lock control mechanism 6.

[0041] Please refer to Figure 1 andFigure 2 , the base 1 serves as the structural foundation of the external door opening device and can be integrated into the door.

[0042] The locking mechanism 2 includes a locking lever 20 rotatably mounted on the base 1 and a first spring 21. The locking lever 20 is limited to the locking state d as shown in Figure 4 and Figure 5a under the action of the first spring 21.

[0043] The unlocking mechanism is drivingly connected to the locking lever 20 to drive the locking lever 20 to rotate from the Figure 4 , Figure 5a shown locking state d to the Figure 4 , Figure 5b shown unlocking state e. The unlocking mechanism applies a unidirectional force to the locking lever 20 to rotate the locking lever 20 from the locking state d to the unlocking state e. When the unidirectional force is cancelled, the locking lever 20 can return to the locking state d under the elastic action of the first spring 21.

[0044] The locking lever 20 can be rotatably connected to the base 1 through a mounting shaft 23. One end of the first spring 21 is connected to the locking lever 20, and the other end of the first spring 21 is connected to the base 1 or the unlocking mechanism.

[0045] Please refer to Figure 1 and Figure 2 , the first spring 21 can be a coil spring or other elastic member that can limit the locking lever 20 in the locking state d through its own restoring force. Both ends of the first spring 21 are respectively connected to the base 1 and the locking lever 20. After the locking lever 20 rotates under the action of an external force, the first spring 21 generates a rotational restoring force on the locking lever 20, and drives the locking lever 20 to return to the locking state d again after the external force acting on the locking lever 20 is cancelled.

[0046] In addition, both ends of the first spring 21 can be respectively connected to the locking lever 20 and the unlocking mechanism. The restoring force of the first spring 21 is in a linear direction, and the locking lever 20 is limited by the unlocking mechanism and the first spring 21.

[0047] The mechanical release mechanism 5 includes a release body 50 rotatably mounted on the base 1. A second spring 55 is connected to the release body 50. The release body 50 is provided with a stroke output member 53. When the locking lever 20 is in the locking state d, it abuts against the end of the release body 50 to make the release body 50 in the locked position; when the locking lever 20 is in the unlocking state e, the second spring 55 drives the release body 50 to rotate to the operable position.

[0048] As shown in Figures 5a to 5dAs shown, when the locking lever 20 is in the locked state d, it abuts against the end of the release body 50 to limit the release body 50. The release body 50 is limited to the locked position. At this time, the second spring 55 is in a stretched state, generating a force for the release body 50 to rotate to the operable position. When the locking lever 20 is in the unlocked state e, it moves away from the end of the release body 50 to cancel the force applied to the release body 50. The release body 50 rotates to the operable position under the elastic action of the second spring 55. At this time, the release body 50 is in a force balance state. When the release body 50 is in the operable position, a force can be applied to the release body 50 manually or electrically on the outer side of the door to drive the release body 50 to rotate further.

[0049] Among them, the release body 50 can be fan-shaped. The central rotation of the release body 50 is sleeved on the rotating shaft installed on the base 1. When the locking lever 20 is in the locked state d, it abuts against the end of the fan-shaped release body 50. The release body 50 and the base 1 are connected by the second spring 55. The second spring 55 can also be a coil spring or other elastic members that can drive the release body 50 to the operable position through its own restoring force.

[0050] The door lock control mechanism 6 is used to control the opening and closing of the door lock. The stroke output member 53 is connected to the door lock control mechanism 6. When the release body 50 moves from the operable position to the full stroke position, the stroke output member 53 drives the door lock control mechanism 6 to unlock the door. As Figure 2 shown, when the release body 50 further rotates from the operable position to the full stroke position, the stroke output member 53 pulls the door lock control mechanism 6 to separate from the vehicle body, thereby unlocking the door.

[0051] Among them, the door lock control mechanism 6 can be a conventional flexible or rigid door locking structure.

[0052] The door external opening device provided by the embodiment of the present application can drive the mechanical release mechanism 5 to release the door lock control mechanism 6 through the deinsurance mechanism, realizing the emergency door opening function of the vehicle after power failure, power shortage or collision power off. Moreover, it requires fewer electronic components, has high reliability and low cost.

[0053] In an alternative embodiment of the deinsurance mechanism, the deinsurance mechanism includes a mechanical deinsurance mechanism 3. The mechanical deinsurance mechanism 3 includes a swing arm 30 and a connecting rod 31 that are rotatably connected. The swing arm 30 is rotatably installed on the base 1. The connecting rod 31 is unidirectionally connected to the locking lever 20 to drive the locking lever 20 to rotate from the locked state d to the unlocked state e. As Figures 1 to 2As shown, the rotating shaft 33 of the swing arm 30 is rotatably installed on the base 1. A third spring 32 is connected between the rotating shaft 33 of the swing arm 30 and the base 1. The third spring 32 can be an elastic member with a restoring effect such as a coil spring. The swing arm 30 is limited to the initial position under the action of the third spring 32. When the swing arm 30 rotates under force, it drives the connecting rod 31 to rotate accordingly, and further drives the locking rod 20 to rotate accordingly, so that the locking rod 20 moves from Figure 5a the locking state d shown in Figures 5b to 5d to the unlocking state e shown in

[0054] In an alternative embodiment where the connecting rod 31 is unidirectionally connected to the locking rod 20, a first blocking structure 22 is provided on one side of the locking rod 20, and a first driving structure is provided on the connecting rod 31. When the locking rod 20 is in the locking state d, the first driving structure abuts against the side of the first blocking structure 22 away from the swing arm 30, or there is a gap between the first driving structure and the side of the first blocking structure 22 away from the swing arm 30, and the connecting rod 31 does not exert a force on the locking rod 20. The first driving structure drives the first blocking structure 22 to rotate towards the side close to the swing arm 30, so that the locking rod 20 is in the unlocking state e. When the connecting rod 31 drives the first driving structure to rotate, the first driving structure drives the locking rod 20 to have a tendency to rotate by abutting against the first blocking structure 22, and the locking rod 20 rotates to the unlocking state e by overcoming the acting force of the first spring 21; when the connecting rod 31 is reset, the locking rod 20 returns to the locking state d again under the action of the first spring 21.

[0055] Among them, in the first blocking structure 22 and the first driving structure, one can be a plate-shaped, block-shaped, or strip-shaped structure, and the other can be a one-way connection structure such as a convex structure that contacts and further drives after movement; it can also be that one is a groove-shaped structure with an opening on one side, and the other is a one-way connection structure such as a convex structure that contacts and further drives after movement. In an alternative embodiment for controlling the rotation of the swing arm 30, the mechanical safety release mechanism 3 further includes an identity recognition member 56, and a tooth-shaped feature 57 is provided on the identity recognition member 56; a groove feature 34 adapted to the tooth-shaped feature 57 is provided on the rotating shaft 33 of the swing arm 30. After the tooth-shaped feature 57 is inserted into the groove feature 34, the identity recognition member 56 can drive the swing arm 30 to rotate. As Figure 6 shown, the identity recognition member 56 performs identity recognition through the tooth-shaped feature 57. After the tooth-shaped feature 57 is inserted into the groove feature 34, the identity recognition is completed, and the rotation limiting structure on the rotating shaft 33 retracts from the base 1 to cancel the limit on the rotating shaft 33. The rotating shaft 33 is in a rotatable state, and the swing arm 30 can be driven to rotate by rotating the identity recognition member 56 through the handle on the identity recognition member 56.

[0056] Among them, the identity recognition member 56 can be inserted into the groove feature 34 from the outer opening of the vehicle door. The outer opening of the vehicle door can be provided on the door handle.

[0057] When the identity recognition member 56 is removed, the mechanical safety release mechanism 3 tends to move towards the initial position under the action of the third spring 32, driving the connecting rod 31 to reset; the operating handle 52 is rotated reversely to the locking position, and the locking rod 20 moves from the unlocked state e to the locked state d under the action of the first spring 21, and rotates to abut against the end face of the release body 50 to limit the release body 50 in the locking position.

[0058] In another alternative embodiment of the safety release mechanism, the safety release mechanism includes an electric safety release mechanism 4. The electric safety release mechanism 4 includes an output rod 41 and an electric driver 40 that drives the output rod 41 to be telescopically arranged. The output rod 41 is unidirectionally connected to the locking rod 20 to drive the locking rod 20 to move from the locked state d to the unlocked state e; or the output rod 41 is non-unidirectionally connected to the locking rod 20 to drive the locking rod 20 to move from the locked state d to the unlocked state e, and to move from the unlocked state e to the locked state d. The output rod 41 can be non-unidirectionally connected to the locking rod 20 by fixed connection. The electric driver 40 can be a structure such as an electric cylinder, a combination of a motor and a rack and pinion, etc. that can drive the output rod 41 to perform linear motion.

[0059] Among them, the two ends of the first spring 21 can be respectively connected to the locking rod 20 and the electric safety release mechanism 4. When the locking rod 20 is in the locked state, the locking rod 20 is in a force balance state; when the output rod 41 extends or the connecting rod 31 extends to drive the locking rod 20 to move to the unlocked state, the first spring 21 is in a tension state. When the output rod 41 retracts or the connecting rod 31 resets, the locking rod 20 moves back to the locked state under the restoring force of the first spring 21. Further, the electric safety release mechanism 4 further includes a controller, and the controller is control-connected to the electric driver 40. The controller can be a mobile electric switch, and the electric driver 40 is controlled to move by pressing the button of the electric switch.

[0060] After the electric driver 40 drives the output rod 41 to retract, the operating handle 52 is rotated reversely to the locking position, and the locking rod 20 moves from the unlocked state e to the locked state d under the action of the first spring 21, and rotates to abut against the end face of the release body 50 to limit the release body 50 in the locking position.

[0061] In an alternative embodiment where the output rod 41 is unidirectionally connected to the locking rod 20, a second blocking structure is provided on the other side of the locking rod 20, and a second driving structure is provided on the output rod 41. When the locking rod 20 is in the locked state d, the second driving structure abuts against the side of the second blocking structure away from the electric driver 40, or there is a gap between the second driving structure and the side of the second blocking structure away from the electric driver 40. The second driving structure drives the second blocking structure to rotate towards the side close to the electric driver 40, so that the locking rod 20 is in the unlocked state e. When the second driving structure does not apply force to the second blocking structure, the locking rod 20 maintains the locked state d under the action of the first spring 21; when the output rod 41 drives the second driving structure to rotate, the second driving structure drives the locking rod 20 to rotate by abutting against the second blocking structure, and the locking rod 20 rotates to the unlocked state e against the action of the first spring 21; when the output rod 41 is reset, the locking rod 20 returns to the locked state d again under the action of the first spring 21.

[0062] Among them, in the second blocking structure and the second driving structure, one can be a plate-like, block-like, or strip-like structure, and the other can be a one-way connection structure such as a convex structure that contacts it and has a driving effect after further movement; it can also be that one is a groove-like structure with an opening on one side, and the other is a one-way connection structure such as a convex structure that contacts it and has a driving effect after further movement.

[0063] Among them, the output rod 41 and the connecting rod 31 are respectively arranged on the front and rear sides of the locking rod 20 and are independently unidirectionally connected to the locking rod 20, achieving the effect of controlling the locking rod 20 respectively through the mechanical safety release mechanism 3 and the electric safety release mechanism 4.

[0064] In an alternative embodiment where the stroke output member 53 controls the opening and closing of the door lock control mechanism 6, the stroke output member 53 includes a limiting port 54, the door lock control mechanism 6 includes a head 60 slidably arranged in the limiting port 54, the release body 50 rotates from the locked position to the operable position, and the head 60 slides to the bottom of the limiting port 54, as Figure 5d shown, after the release body 50 rotates from the operable position to the full stroke position, the head 60 rises together with the bottom of the limiting port 54.

[0065] Among them, the limiting port 54 can be an arc-shaped limiting port 54, as Figure 1 and Figure 2 shown, the arc-shaped limiting port 54 has a circular angle of about 90°. When the release body 50 is in the locked position, the top of the arc-shaped limiting port 54 is in the vertical state, the bottom of the arc-shaped limiting port 54 is in the horizontal state, and the head 60 is located at the top of the arc-shaped limiting port 54; when the release body 50 rotates to Figure 5dWhen in the operable position shown, the release body 50 is released and rotates counterclockwise by approximately 90°. The top of the arc-shaped limiting opening 54 is in a horizontal state, and the bottom of the arc-shaped limiting opening 54 is in a vertical state. The end 60 slides to the bottom of the arc-shaped limiting opening 54, and the arc-shaped limiting opening 54 has no effective stroke output for the end 60, and the position of the end 60 does not change. When the release body 50 rotates further counterclockwise, the bottom of the arc-shaped limiting opening 54 drives the end 60 to move upward, thereby driving the door lock control mechanism 6 to lift and separate from the vehicle body, unlocking the door lock control mechanism 6.

[0066] In addition, the limiting opening 54 can also be a linear limiting opening, or a combination of a linear limiting opening and an arc-shaped limiting opening, etc., to ensure that when the release body 50 moves from the locked position to the operable position, the limiting opening 54 has no effective stroke output for the end 60; when the release body 50 moves from the operable position to the full stroke position, the limiting opening 54 drives the end 60 to move upward to unlock the door lock control mechanism 6. In an alternative embodiment where the release body 50 rotates from the operable position to the full stroke position, an operating handle 52 is provided on the release body 50, and the operating handle 52 is located outside the substrate; when the release body 50 is in the locked position, the operating handle 52 is hidden inside the door handle 8; when the release body 50 is in the operable position, the operating handle 52 rotates to at least partially extend outside the door handle 8. As Figures 3a to 3b shown, when the release body 50 is in the locked position, the corresponding operating handle 52 is in Figure 3a and Figure 3b the vertical state a shown, hidden inside the vehicle body handle; when the release body 50 is in the operable position, the corresponding operating handle 52 rotates to Figure 3a and Figure 3c the horizontal state or a state close to horizontal b shown and at least partially appears outside the door handle 8. At this time, a force can be applied to the operating handle 52 by hand or other components to drive the operating handle 52 to further rotate to Figure 3a and Figure 3d the full stroke position c shown, thereby unlocking the door lock control mechanism 6.

[0067] By manually or mechanically pushing the operating handle 52 in the reverse direction to the locked position, the locking lever 20 rotates to the locked state d under the action of the first spring 21, so that the operating handle 52 is held in the locked position.

[0068] In an alternative embodiment, the external door opening device further includes an electric release signal triggering mechanism 7, which is electrically connected to the door lock control mechanism 6 through an electrical signal control; the electric release signal triggering mechanism 7 includes at least one of a door handle 8 and a door switch. When the door handle 8 is rotated or the door switch is pressed, an opening signal is sent to the electric release signal triggering mechanism 7. After receiving the opening signal, the electric release signal triggering mechanism 7 drives the unlocking member of the door lock control mechanism 6 to unlock electrically, so that the door opens.

[0069] In an alternative embodiment, the color of the operating handle 52 is set differently from the color of the door handle 8, so as to facilitate the identification of the operating handle 52 when the operating handle 52 is rotated to the operable position b, and increase the convenience of further rotating the operating handle 52 to the full stroke position c.

[0070] The present application also provides a vehicle, including a door and the external door opening device according to any one of the above embodiments, and the external door opening device is located on the door. Through the external door opening device, it is possible to open the door in an emergency state such as vehicle power-off, power shortage or collision, and it uses fewer electronic components, has high stability and low cost.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
