Description

Technical Field

[0001] The utility model relates to the field of parking locks, in particular to a parking lock core and a parking lock with an emergency structure. Background Art

[0002] A parking lock is a mechanical device installed on the ground to prevent others from occupying the parking space or restrict vehicles from leaving the parking space.

[0003] Chinese patent CN112796253B discloses a novel flatbed parking lock, wherein the bevel gear set includes a bevel gear on a manual crank and a bevel gear on a lead screw. When the manual crank is not used for emergency, the bevel gear on the manual crank and the bevel gear on the lead screw are separated from each other. When the manual crank is used for emergency, the bevel gear on the manual crank and the bevel gear on the lead screw are meshed with each other, and the bevel gear set is used to drive the lead screw to rotate, so that the baffle can be rotated when the motor fails or the power is off; further, it adopts a technical solution in which the motor drives the baffle to flip through the lead screw, the nut slider and the rocker mechanism. In order to realize the linear sliding of the nut slider along the lead screw, a linear slide groove is directly made on the rocker mechanism, and the rocker mechanism is used to prevent the nut slider from rotating. The rocker mechanism and the baffle are coaxially arranged, and the rocker mechanism and the baffle both flip around the main axis.

[0004] This technical solution has the following technical problems: (1) This method requires rotating the bevel gear on the manual crank each time it is used until the bevel gear on the manual crank engages with the bevel gear on the lead screw, which makes the operation difficult. (2) The rocker mechanism and the nut slider rotate relative to each other while moving relative to each other. The linear slide not only reduces the overall strength of the rocker mechanism, but also increases the assembly difficulty and transmission complexity between the rocker mechanism and the nut slider. During the long-term use of the parking lock, especially when the baffle is impacted by the vehicle, the rocker mechanism is prone to deformation and fracture. (3) The coaxial arrangement of the rocker mechanism and the baffle results in a large swing amplitude of the rocker mechanism. The motor needs to output a large torque to flip the baffle, which is not conducive to the miniaturization and flattening design of the parking lock. Utility Model Content

[0052] See also Figure 1-Figure 8 The utility model discloses a parking lock mechanism with an emergency structure, comprising: a driving mechanism 10, the driving mechanism 10 comprises a driving unit 101; a rotating member 20; a transmission mechanism 30, the transmission mechanism 30 comprises a transmission member 301, one end of the transmission member 301 is transmission-connected to the output end of the driving unit 101, and the other end of the transmission member 301 is transmission-connected to the rotating member 20; when the driving unit 101 drives the transmission member 301 to rotate, the transmission member 301 drives the rotating member 20 to rotate together; when the driving unit 101 stops, the transmission member 301 is driven to rotate together by rotating the rotating member 20.

[0053] In the parking lock mechanism with an emergency structure of the utility model, one end of the transmission member 301 is transmission-connected to the output end of the drive unit 101, and the other end of the transmission member 301 is transmission-connected to the rotating member 20. When the drive unit 101 stops, the transmission member 301 is driven to rotate together by rotating the rotating member 20, so that the rotating member 20 can be used to implement emergency operation. There is no clutch step between the rotating member 20 and the transmission member 301, and the operation is convenient.

[0054] In an embodiment of the utility model, one end of the transmission member 301 is nested with the output end of the driving unit 101, and the other end of the transmission member 301 is nested with the rotating member 20; there is a buffer gap between the axial direction of the transmission member 301 and the axial direction of the rotating member 20; when the transmission member 301 is subjected to external impact force, the transmission member 301 moves relative to the rotating member 20 in the buffer gap.

[0055] In the embodiment of the utility model, a first connecting hole 302 and a second connecting hole 303 are respectively provided at the two axial ends of the transmission member 301. One axial end of the transmission member 301 is plugged into the output end of the driving unit 101 through the first connecting hole 302, and the other axial end of the transmission member 301 is plugged into the rotating member 20 through the second connecting hole 303. The first connecting hole 302 and the second connecting hole 303 are both polygonal holes, and the part where the output end of the driving unit 101 is plugged into the first connecting hole 302 is a polygonal shaft, and the part where the rotating member 20 is plugged into the second connecting hole 303 is a polygonal shaft.

[0056] That is, the radial cross-section of the part where the output end of the driving unit 101 is plugged into the first connecting hole 302 is a polygon, and the radial cross-section of the part where the rotating member 20 is plugged into the second connecting hole 303 is a polygon; in this way, through the cooperation of the polygonal hole and the polygonal axis, the output end of the driving unit 101 can drive the transmission member 301 to rotate, and the transmission member 301 can also move axially relative to the output end of the driving unit 101, the rotating member 20 can rotate with the transmission member 301, the rotating member 20 can also drive the transmission member 301 to rotate, and the transmission member 301 can also move axially relative to the rotating member 20.

[0057] In an embodiment of the utility model, the parking lock mechanism with an emergency structure also includes an elastic member 40, which is arranged in the second connecting hole 303, and one axial end of the elastic member 40 abuts against the transmission member 301, and the other axial end of the elastic member 40 abuts against the rotating member 20; when the transmission member 301 is subjected to external impact force, the transmission member 301 moves toward the direction close to the rotating member 20 and squeezes the elastic member 40; when the external impact force on the transmission member 301 disappears, the elastic member 40 drives the transmission member 301 to reset.

[0058] Specifically, the elastic member 40 is a spring or a rubber column.

[0059] Based on the above structure, the elastic member 40 is arranged in the second connecting hole 303 to effectively reduce the overall length of the parking lock movement with the emergency structure.

[0060] In an embodiment of the utility model, the driving mechanism 10 also includes a support seat 102, which is sleeved on the outside of the transmission member 301, and a first limiting portion 103 is provided at the end of the support seat 102 close to the transmission member 301, a first shoulder 50 is provided on the rotating member 20, and a second shoulder 304 is provided at one end of the transmission member 301 close to the support seat 102; the end of the transmission member 301 close to the rotating member 20 is axially spaced apart from the first shoulder 50 at a first spacing, and the first limiting portion 103 and the second shoulder 304 are spaced apart from each other by a second spacing, and the second spacing is smaller than the first spacing.

[0061] Thus, the buffer gap between the axial direction of the transmission member 301 and the axial direction of the rotating member 20 is referred to as the second spacing, and the first spacing prevents the transmission member 301 from hitting the rotating member 20 during axial movement, and the first spacing plays a role of avoiding air.

[0062] Furthermore, the driving mechanism 10 also includes a fixed seat 104, which is sleeved on the outside of the connection position between the transmission member 301 and the driving unit 101; a third shoulder 105 is provided on the output end of the driving unit 101, a fourth shoulder 305 is provided at one end of the transmission member 301 close to the driving unit 101, and a second limiting portion 106 is provided on the fixed seat 104; the end of the transmission member 301 close to the driving unit 101 is axially spaced apart from the third shoulder 105 at a third spacing, the second limiting portion 106 is spaced apart from the fourth shoulder 305 at a fourth spacing, and the fourth spacing is smaller than the third spacing.

[0063] Taking the example that there is only a buffer gap between the axial direction of the transmission member 301 and the axial direction of the support seat 102, and the elastic member 40 is arranged in the second connection hole 303, the specific movement process of the transmission member 301 when subjected to external impact force is as follows:

[0064] When the transmission member 301 is not subjected to external impact force, under the action of the elastic member 40, the transmission member 301 abuts against the fixed seat 104, specifically, the fourth shoulder 305 on the transmission member 301 abuts against the second limiting portion 106 of the fixed seat 104, and the second distance constitutes a buffer gap between the transmission member 301 and the support seat 102.

[0065] When the transmission member 301 is subjected to an external impact force in the first direction, the transmission member 301 moves toward the rotating member 20 and squeezes the elastic member 40. During this process, the first spacing and the second spacing are reduced, and the third spacing and the fourth spacing are increased. When the external impact force on the transmission member 301 in the first direction is large enough, the second shoulder 304 on the transmission member 301 impacts the first limit portion 103 on the support seat 102.

[0066] When the external impact force in the first direction on the transmission member 301 disappears, the elastic member 40 is reset. Under the action of the elastic member 40, the transmission member 301 moves toward the output end of the drive unit 101. During this process, the first spacing and the second spacing both increase, and the third spacing and the fourth spacing both decrease. The fourth shoulder 305 on the transmission member 301 abuts against the second limit portion 106 on the fixed seat 104.

[0067] See also Figure 3-Figure 4 , setting the direction of driving the transmission member 301 to move to the left direction as the first direction; of course, an elastic member 40 can also be arranged in the first connecting hole 302, so that when the transmission member 301 is subjected to external impact force in the second direction, buffering can also be achieved, and the second direction refers to the direction of driving the transmission member 301 to move to the right direction.

[0068] In this way, the rotating member 20 is inserted into the second connecting hole 303, and the support seat 102 is sleeved on the outside of the rotating member 20 and the transmission member 301. The rotating member 20, the transmission member 301 and the support seat 102 form a three-layer structure that is nested with each other, thereby supporting and protecting the transmission member 301. When the transmission member 301 is subjected to the impact force and moves axially, the transmission member 301 transmits the impact force to the outer peripheral side of the support seat 102; the output end of the drive unit 101 is inserted into the first connecting hole 302, and the fixed seat 104 is sleeved on the outside of the transmission member 301 and the drive unit 101. The output end of the drive unit 101, the transmission member 301 and the fixed seat 104 form a three-layer structure that is nested with each other, thereby supporting and protecting the transmission member 301. When the transmission member 301 is subjected to the elastic force of the elastic member 40 and moves axially, the transmission member 301 transmits the impact force to the outer peripheral side of the fixed seat 104.

[0069] Specifically, the support seat 102 and the fixing seat 104 can be made in one piece or in separate pieces. The support seat 102 can be made in separate pieces to reduce the processing complexity of the support seat 102 , and the fixing seat 104 can be made in separate pieces to reduce the processing complexity of the fixing seat 104 .

[0070] In the embodiment of the utility model, the support seat 102 is also sleeved outside the rotating member 20, and a bearing 60 is provided between the support seat 102 and the rotating member 20. The bearing 60 is provided to improve the rotation smoothness of the rotating member 20.

[0071] Specifically, the bearing 60 is a rotating bearing, and the bearing 60 includes a rotating inner ring and a fixed outer ring. The rotating inner ring is fixedly connected to the rotating member 20, and the fixed outer ring is fixedly connected to the support seat 102, thereby realizing the rotation of the rotating member 20 and the support seat 102.

[0072] In the embodiment of the utility model, a connecting portion 70 is provided on the end of the rotating member 20 away from the transmission member 301. The connecting portion 70 is used to connect an external emergency handle. The connecting portion 70 can be a slot or a protrusion, so as to achieve connection with the emergency handle.

[0073] In the embodiment of the utility model, the parking lock mechanism with the emergency structure includes a housing 80 , which is disposed outside the transmission mechanism 30 , and an emergency operation window 90 is disposed at the connection portion 70 of the housing 80 .

[0074] Specifically, when the drive unit 101 is shut down due to power failure or fault, the emergency operation window 90 is opened, and the emergency handle and the connecting part 70 are used to rotate the rotating part 20, thereby driving the transmission part 301 to rotate. The utility model can realize emergency operation by directly rotating the transmission part 301, which is easy to operate. This is different from the prior art that requires continuous adjustment of the bevel gear on the crank handle until it engages with the bevel gear on the screw rod.

[0075] In an embodiment of the utility model, the transmission mechanism 30 also includes a moving part 306 and a linear guide rail 307. The moving part 306 is threadedly connected to the transmission part 301, and the moving part 306 and the linear guide rail 307 are slidably matched; when the driving unit 101 drives the transmission part 301 to rotate, the transmission part 301 drives the moving part 306 to move along its axial direction, and the moving part 306 moves along the linear guide rail 307 at the same time.

[0076] See also Figure 1-Figure 8 A parking lock comprises the above-mentioned parking lock movement with emergency structure, and also comprises a connecting arm 100, a connecting shaft 110, a stopper 120, a main shaft 130 and a connecting seat 140, one end of the connecting arm 100 is rotatably connected to the moving member 306, the other end of the connecting arm 100 is rotatably connected to the stopper 120 through the connecting shaft 110, and the stopper 120 is rotatably connected to the connecting seat 140 through the main shaft 130; the main shaft 130 is arranged parallel to the connecting shaft 110; when the driving unit 101 drives the transmission member 301 to rotate, the transmission member 301 drives the moving member 306 to move, and the moving member 306 drives the stopper 120 to flip around the main shaft 130 through the connecting arm 100 to open or close the stopper 120.

[0077] In the parking lock of the present invention, the main shaft 130 and the connecting shaft 110 are arranged in parallel and at intervals, and the transmission mechanism 30, the connecting arm 100, the connecting shaft 110, the main shaft 130, the stopper 120 and the connecting seat 140 constitute a slider connecting rod mechanism, and the stopper 120 is driven to flip by cooperating with the connecting arm 100 through the movement of the moving part 306, so that the driving unit 101 outputs a smaller torque to drive the stopper 120 to flip, and the swing amplitude of the connecting arm 100 is smaller, which is conducive to the flat design of the parking lock.

[0078] Specifically, the driving unit 101 is a motor, the transmission part 301 is a screw, the moving part 306 is a nut, and the screw and the nut are threadedly connected; the linear guide 307 is arranged in parallel on the side of the screw, and the nut is slidingly connected to the linear guide 307; when the motor drives the screw to rotate, the nut moves along the screw, and the nut slides along the linear guide 307.

[0079] The specific use process of the present invention is as follows:

[0080] In the initial state, the blocking member 120 is in a flat and closed state, and the vehicle can pass through the parking lock. At this time, the vehicle can enter and exit the parking space freely.

[0081] The motor rotates forward, and drives the blocking member 120 to flip forward around the main axis 130 through the transmission mechanism 30, the connecting arm 100, and the connecting shaft 110. The blocking member 120 flips to an upright open state, and the blocking member 120 blocks the vehicle, thereby preventing the vehicle from freely entering and exiting the parking space.

[0082] The motor rotates in the reverse direction, and drives the blocking member 120 to flip in the reverse direction around the main axis 130 through the transmission mechanism 30, the connecting arm 100, and the connecting shaft 110.
