Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and particularly relates to a power-off emergency door locking structure for a vehicle door. Background Art

[0002] With the continuous development and growth of the world's automobile industry, the position of the automobile industry in the world economic development has become increasingly prominent. The automobile industry has a huge role and far-reaching impact on the development of the world economy and social progress. An automobile door lock is an important component of an automobile body and is a special component integrating safety, decoration, and technology. An automobile door lock generally has an in-car door opening system and an out-of-car and electric door opening system. The in-car door opening system is used to open the vehicle door from inside the car, and the out-of-car and electric door opening system is used to open the vehicle door from outside the car. In addition, to prevent the vehicle door from accidentally opening due to the vehicle body rolling over in the event of an accident such as a collision, a clutch structure is usually provided, and an electronic control unit is used to control the clutch structure to switch between clutch states. When the system detects a vehicle body rollover signal, the electronic control unit immediately makes a feedback and controls the clutch structure to switch states, so that the vehicle door is automatically locked, preventing casualties caused by the accidental opening of the vehicle door when the vehicle body rolls over. However, the method of electronically controlling the clutch structure to switch, although the feedback is rapid, has a problem that when the vehicle loses power, the electronic control unit stops working and cannot control the clutch structure to switch, resulting in a safety hazard and urgent improvement is needed. Content of the Utility Model

[0003] The purpose of the utility model is to provide a power-off emergency door locking structure for a vehicle door, which has the effect of mechanically locking the vehicle door when the vehicle loses power and improving the vehicle use safety.

[0004] The above technical purpose of the utility model is achieved by the following technical solutions: A power-off emergency door locking structure for a vehicle door includes a frame. An outer opening arm and an inner opening arm are rotatably arranged on the frame through a rotating shaft. The outer opening arm is linked with the inner opening arm through a clutch structure to control the opening of the vehicle door.

[0005] It further includes a pressing drive assembly, which can drive the clutch structure to perform clutch switching, so that the outer opening arm and the inner opening arm can be switched between a separated state and a linked state.

[0006] By adopting the above technical solution, the door can be opened by utilizing the linkage effect between the clutch structure, the outer opening arm and the inner opening arm under normal vehicle conditions. When the vehicle experiences a complete power outage, an external driving force is used to press down the pressing drive assembly, causing the clutch structure to switch from the "engaged" state to the "disengaged" state, thereby separating the outer opening arm from the inner opening arm and disconnecting the linkage effect between them, so that the door can always remain in a locked state. Different from the defect that vehicles on the market cannot automatically lock the door when losing power, the utility model can drive the clutch structure to disengage and engage by pressing down or lifting the pressing drive assembly with an external driving force, and has the effect of mechanically controlling the door lock when the vehicle loses power and improving the vehicle use safety.

[0007] A further setting of the utility model is that: the pressing drive assembly includes a push rod and a linkage arm. The push rod is slidably arranged on the frame, the linkage arm is rotatably arranged on the frame, and the push rod can drive the linkage arm to rotate, so that the linkage arm drives the clutch structure to perform disengagement and engagement switching.

[0008] By adopting the above technical solution, an external driving force presses the push rod to drive the linkage arm to rotate, and the linkage arm then drives the clutch structure to perform disengagement and engagement switching.

[0009] A further setting of the utility model is that: an elastic member is arranged between the push rod and the frame, and the elastic member always has a tendency to drive the push rod away from the linkage arm.

[0010] By adopting the above technical solution, the addition of the elastic member enables the push rod to automatically reset when the pressing driving force of the external driving force on the push rod disappears, and the outer opening arm and the inner opening arm remain separated.

[0011] A further setting of the utility model is that: the elastic member is a tension spring. A hook portion is arranged at one end of the push rod close to the linkage arm, and a positioning post is arranged on the frame. One end of the tension spring is fixedly connected to the hook portion, and the other end of the tension spring is fixedly connected to the positioning post.

[0012] A further setting of the utility model is that: a plurality of guiding grooves are formed in the push rod along the length direction, and the push rod and the positioning post are mutually avoided and guidingly matched through the guiding grooves.

[0013] By adopting the above technical solution, the positioning post can be relatively slidably arranged in the guiding groove, the sliding stroke of the push rod is limited, and in addition, by using the guiding effect of the positioning post and the guiding groove, the sliding direction of the push rod on the frame is more consistent.

[0014] A further setting of the present utility model is as follows: The clutch structure includes a clutch member and a first track groove. The first track groove is formed on the inner opening arm. The clutch member is slidably disposed in the first track groove. The clutch member is coaxially provided with a linkage portion. When the outer opening arm and the inner opening arm are in a linkage state through the linkage portion, the outer opening arm can drive the inner opening arm to rotate through the linkage portion of the clutch member.

[0015] By adopting the above technical solution, when the clutch structure is in the "closed" state, the inner opening arm and the outer opening arm are in a relative linkage state through the clutch member. At this time, the clutch member is located at the first position of the first track groove. When the clutch member is pushed and slid from the first position to the second position of the first track groove by pressing the driving component under the action of an external driving force, the clutch structure is in the "open" state. At this time, the inner opening arm and the outer opening arm are in a separated state from each other, thereby cutting off the linkage effect between the inner opening arm and the outer opening arm, making the door unable to be opened from the outside or inside of the vehicle body.

[0016] A further setting of the present utility model is as follows: The clutch member includes anti-detachment portions symmetrically distributed in the middle. An annular groove is formed between the two anti-detachment portions on both sides. The clutch member is embedded on the inner opening arm through the annular groove, and is anti-detachedly matched with the inner opening arm through the anti-detachment portions on both sides.

[0017] By adopting the above technical solution, the anti-detachment portions on both sides can stop and prevent detachment on both sides of the inner opening arm, preventing the clutch member from slipping out of the first track groove.

[0018] A further setting of the present utility model is as follows: The linkage arm includes a rotating connection portion, a first bifurcated portion, and a second bifurcated portion. The linkage arm is rotatably connected to the frame through the rotating connection portion. The first bifurcated portion is provided with a convex column. A mating groove is formed at the end of the push rod corresponding to the convex column, and the convex column is correspondingly located in the mating groove.

[0019] By adopting the above technical solution, when the push rod is pressed, the inner wall of the mating groove at the end of the push rod pushes the convex column to move, thereby driving the first bifurcated portion to rotate, causing the linkage arm to drive the second bifurcated portion to rotate synchronously, and further driving the clutch structure to perform clutch switching. The setting of the mating groove and the convex column enables the convex column to rotate relative to the mating groove, preventing jamming between the push rod and the linkage arm when the push rod drives the linkage arm to rotate.

[0020] A further setting of the present utility model is as follows: The clutch structure includes a clutch member. The clutch member includes a linkage portion. A second track groove is formed on the second bifurcated portion corresponding to the linkage portion. The clutch member is guidingly matched with the second track groove through the linkage portion.

[0021] By adopting the above technical solution, when the linkage arm rotates, it can drive the clutch member to achieve high-precision sliding switching between the clutch positions through the second track groove, preventing the clutch structure from getting stuck during the clutch switching.

[0022] A further setting of the present utility model is that: the linkage arm is provided with a third bifurcated portion, a driving controller is fixedly arranged on the frame, a driving rod is arranged at the output end of the driving controller, the driving rod is connected to the third bifurcated portion, and the driving controller can drive the driving rod to rotate, so that the driving rod drives the linkage arm to rotate through the third bifurcated portion.

[0023] By adopting the above technical solution, when the vehicle is not powered off, the driving controller can be used to drive the driving rod to rotate, and the rotation of the driving rod then drives the linkage arm to rotate, so as to realize the electric locking of the vehicle door when the vehicle is powered on.

[0024] In summary, the present utility model has the following beneficial effects:

[0025] The outer opening arm and the inner opening arm are rotatably arranged on the frame of the vehicle door, and are connected by a clutch structure between the outer opening arm and the inner opening arm. At the same time, a pressing driving assembly is arranged on the frame. The pressing driving assembly includes a push rod and a linkage arm. The push rod is slidably arranged on the frame, and the linkage arm is rotatably arranged on the frame. By pressing down the push rod, the linkage arm is driven to rotate, and the linkage arm drives the clutch structure to perform clutch switching, so that the outer opening arm and the inner opening arm can be switched between the separated state and the linkage state. Under normal vehicle conditions, the clutch structure can be used to open the vehicle door through the linkage effect with the outer opening arm and the inner opening arm. When the vehicle has a complete power failure, by applying an external driving force to press down the pressing driving assembly, the clutch structure is switched from the "engaged" state to the "disengaged" state, so that the outer opening arm and the inner opening arm are separated from each other, and the linkage effect between the outer opening arm and the inner opening arm is disconnected, so that the vehicle door can always be kept in the locked state. Different from the defect that the vehicle door cannot be automatically locked when the vehicle loses power in the market, the present utility model can drive the clutch structure to perform clutch switching by pressing down or lifting the pressing driving assembly with an external driving force, and has the effects of mechanically controlling the locking of the vehicle door when the vehicle loses power and improving the safety of vehicle use.

Specific embodiments

[0032] The present utility model will be further described below with reference to the accompanying drawings.

[0033] An emergency power-off door locking structure for a vehicle door, as Figure 1 shown, includes a frame 1. An outer opening arm 2 and an inner opening arm 3 are rotatably provided on the frame 1 through a rotating shaft 11. The outer opening arm 2 is linked with the inner opening arm 3 through a clutch structure and is used to control the opening of the vehicle door. In this embodiment, the outer opening arm 2 is connected to the outer opening and electric opening systems of the vehicle door, and the inner opening arm 3 is connected to the vehicle door lock system, both of which are used to realize the opening of the vehicle door; it further includes a pressing driving component 4. The pressing driving component 4 can drive the clutch structure to perform clutch switching, so that the outer opening arm 2 and the inner opening arm 3 can be switched between a separated state and a linked state.

[0034] As Figure 1-2As shown, the pressing drive assembly 4 includes a push rod 41 and a linkage arm 42. The push rod 41 is slidably arranged on the frame 1, and the linkage arm 42 is rotatably arranged on the frame 1. The push rod 41 can drive the linkage arm 42 to rotate, so that the linkage arm 42 drives the clutch structure to perform clutch switching. By mechanically pressing the push rod 41 with an external driving force to drive the linkage arm 42 to rotate, the linkage arm 42 then drives the clutch structure to perform clutch switching. An elastic member 5 is provided between the push rod 41 and the frame 1. The elastic member 5 always has a tendency to drive the push rod 41 away from the linkage arm 42 and extend out of the vehicle body. The addition of the elastic member 5 enables the push rod 41 to automatically reset when the pressing driving force of the external driving force on the push rod 41 disappears, and the outer opening arm 2 and the inner opening arm 3 remain in a separated state. The elastic member 5 is a tension spring. One end of the push rod 41 close to the linkage arm 42 is provided with a hook portion 411, and the frame 1 is provided with two positioning posts 12. One end of the tension spring is fixedly connected to the hook portion 411, and the other end of the tension spring is fixedly connected to the positioning post 12. The push rod 41 is provided with two guiding grooves 41a along its length direction. The push rod 41 and the positioning post 12 avoid each other and are guidingly engaged through the guiding grooves 41a, so that the positioning post 12 can be relatively slidably arranged in the guiding grooves 41a, which limits the sliding stroke of the push rod 41. In addition, by using the guiding effect of the positioning post 12 and the guiding grooves 41a, the sliding direction of the push rod 41 on the frame 1 is more consistent. There are two positioning posts 12. The push rod 41 is provided with two avoiding grooves corresponding to the two positioning posts 12. The two positioning posts 12 are arranged on the frame 1 and are in different planes. The two positioning posts 12 are slidably engaged with the corresponding avoiding grooves to play a guiding role, so that the moving direction of the push rod 41 is more consistent. In addition, in this embodiment, the push rod 41 is arranged at a concealed position of the vehicle door. When the vehicle door is closed, the push rod 41 is blocked by the vehicle door and cannot be operated.

[0035] As Figure 3-5As shown, the clutch structure includes a clutch member 6 and a first track groove 3a. The first track groove 3a is formed in the inner opening arm 3. The clutch member 6 is slidably disposed in the first track groove 3a. The clutch member 6 is coaxially provided with a linkage portion 61. When the outer opening arm 2 and the inner opening arm 3 are in a linkage state through the linkage portion 61, the outer opening arm 2 can drive the inner opening arm 3 to rotate through the linkage portion 61 of the clutch member 6. When the clutch structure is in the "closed" state, the inner opening arm 3 and the outer opening arm 2 are in a relative linkage state through the clutch member 6. At this time, the clutch member 6 is located at the first position of the first track groove 3a. When the clutch member 6 is pushed and slid from the first position to the second position of the first track groove 3a by pressing the driving assembly 4 under the action of an external driving force, the clutch structure is in the "open" state. At this time, the inner opening arm 3 and the outer opening arm 2 are in a separated state from each other, thereby cutting off the linkage between the inner opening arm 3 and the outer opening arm 2, making the door unable to be opened from the outside or inside of the vehicle body; the clutch member 6 includes anti-disengagement portions 62 symmetrically distributed in the middle. An annular groove 6a is formed between the two anti-disengagement portions 62 on both sides. The clutch member 6 is embedded in the inner opening arm 3 through the annular groove 6a, and is anti-disengaged with the inner opening arm 3 through the anti-disengagement portions 62 on both sides. The anti-disengagement portions 62 on both sides can stop and prevent the inner opening arm 3 from disengaging, preventing the clutch member 6 from disengaging from the first track groove 3a.

[0036] As Figure 1 and Figure 3-5As shown, the linkage arm 42 includes a rotational connection portion 420, a first bifurcated portion 421, and a second bifurcated portion 422. The linkage arm 42 is rotationally connected to the frame 1 through the rotational connection portion 420. The first bifurcated portion 421 is provided with a convex post 4211. A mating groove 41b is formed at the end of the push rod 41 corresponding to the convex post 4211. The convex post 4211 is correspondingly located within the mating groove 41b. When the push rod 41 is pressed, the inner wall of the mating groove 41b at the end of the push rod 41 pushes the convex post 4211 to move, thereby driving the first bifurcated portion 421 to rotate, causing the linkage arm 42 to drive the second bifurcated portion 422 to rotate synchronously, and further driving the clutch structure to perform a clutch switching. The arrangement of the mating groove 41b and the convex post 4211 enables the convex post 4211 to rotate relative to the mating groove 41b, preventing jamming between the two when the push rod 41 drives the linkage arm 42 to rotate; the clutch structure includes a clutch member 6. The clutch member 6 includes a linkage portion 61. The second bifurcated portion 422 is provided with a second track groove 422a corresponding to the linkage portion 61. The second track groove 422a is arranged as an arc groove along the length direction of the second bifurcated portion 422. The clutch member 6 is guidingly engaged with the second track groove 422a through the linkage portion 61, enabling the clutch member 6 to perform a high-precision sliding switching between the clutch positions when the linkage arm 42 rotates, preventing jamming of the clutch structure during the clutch switching; the linkage arm 42 is provided with a third bifurcated portion 423. A drive controller 13 is fixedly arranged on the frame 1. The output end of the drive controller 13 is provided with a drive rod 131. The drive rod 131 is connected to the third bifurcated portion 423. The drive controller 13 can drive the drive rod 131 to rotate, causing the drive rod 131 to drive the linkage arm 42 to rotate through the third bifurcated portion 423. When the vehicle is not powered off, the drive controller 13 can be used to drive the drive rod 131 to rotate, and the rotation of the drive rod 131 further drives the linkage arm 42 to rotate, thereby realizing the electric locking of the vehicle door in the powered-on state of the vehicle; in addition, a torsion spring 424 is arranged between the linkage arm 42 and the frame 1. The torsion spring 424 is used to reset the linkage arm 42 to its stationary state.

[0037] The basic working principle of the present utility model is as follows: An outer opening arm 2 and an inner opening arm 3 are rotatably arranged on the frame 1 of the vehicle door. The outer opening arm 2 and the inner opening arm 3 are connected by a clutch structure. At the same time, a pressing drive assembly 4 is arranged on the frame 1. The pressing drive assembly 4 includes a push rod 41 and a linkage arm 42. The push rod 41 is slidably arranged on the frame 1, and the linkage arm 42 is rotatably arranged on the frame. By pressing down the push rod 41, the linkage arm 42 is driven to rotate. The linkage arm 42 drives the clutch structure to perform clutch switching, so that the outer opening arm 2 and the inner opening arm 3 can be switched between a separated state and a linked state. Under normal vehicle conditions, the clutch structure and the linkage effect between the outer opening arm 2 and the inner opening arm 3 can be used to open the vehicle door. When the vehicle has a complete power failure, by applying an external driving force to press down the pressing drive assembly 4, the clutch structure is switched from the "engaged" state to the "disengaged" state, so that the outer opening arm 2 and the inner opening arm 3 are separated from each other, and the linkage effect between the outer opening arm 2 and the inner opening arm 3 is disconnected, so that the vehicle door can always be kept in a locked state. Different from the defect that the vehicle door cannot be automatically locked when the vehicle loses power in the market, the present utility model can drive the clutch structure to perform clutch switching by pressing down or lifting the pressing drive assembly 4 with an external driving force, and has the effects of mechanically controlling the vehicle door to be locked when the vehicle loses power and improving the vehicle use safety.

[0038] The above is only the preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made according to the structure, features and principles described in the scope of the patent application of the present utility model are included in the scope of the patent application of the present utility model.
