The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model.

[0038] Reference is made to Figures 1-4The utility model provides a parking stall lock, including mounting seat 4, flap 5 and the core that can use in an emergency, the core includes transmission mechanism 1 and drive mechanism, flap 5 rotates and is installed in mounting seat 4, and drive mechanism is connected with transmission mechanism 1, and transmission mechanism 1 is connected with flap 5 transmission. Transmission mechanism 1 is located below flap 5, and is located between the both ends of flap 5 length direction. The parking stall lock still includes emergency mechanism 2, and emergency mechanism 2 includes umbrella gear set 21 and rotating piece 22, and the both ends of umbrella gear set 21 are connected rotating piece 22 and transmission mechanism 1 respectively;Drive mechanism drives transmission mechanism 1 movement to drive flap 5 to rotate to closed state or open state;When drive mechanism stops, rotating piece 22 rotates and drives transmission mechanism 1 movement through umbrella gear set 21 to make flap 5 rotate to closed state or open state.

[0039] The rotating piece 22 of emergency mechanism 2 is connected with transmission mechanism 1 through umbrella gear set 21, so that when the drive mechanism fails or power failure, the rotating piece 22 is rotated and drives transmission mechanism 1 to move through umbrella gear set 21, thereby ensuring the transmission effect of the core, so that when applied to the parking stall lock, the flap 5 can be rotated to the closed state or the open state by using the emergency mechanism 2, thereby achieving the closing and opening of the parking stall lock, and the car can be driven away or locked in time.

[0040] Moreover, compared with the prior art, the transmission mechanism 1 is installed below the flap 5 and connected with the emergency mechanism 2, which is beneficial to reduce the size of the parking stall lock, thereby reducing the space occupied by the parking stall lock, achieving the miniaturization of the parking stall lock, and facilitating the selection of the installation position of the parking stall lock.

[0041] The transmission mechanism 1 includes a lead screw 11 and a nut 12 threadedly connected with the lead screw 11, and the axial end of the lead screw 11 is connected with the umbrella gear set 21 and the drive mechanism. When the drive mechanism drives the lead screw 11 to rotate, the lead screw 11 drives the nut 12 to reciprocate along the axial direction of the lead screw 11, so as to drive the flap 5 to rotate to the closed state or the open state. When the drive mechanism stops, the rotating piece 22 rotates and synchronously drives the lead screw 11 to rotate through the umbrella gear set 21, so as to drive the nut 12 to reciprocate along the axial direction of the lead screw 11, and make the flap 5 rotate to the closed state or the open state. The emergency mechanism 2 and the transmission mechanism 1 of the utility model are in the same plane or parallel planes, which can reduce the height of the core and the space occupied by the core.

[0042] The drive mechanism and emergency mechanism 2 are connected to the same axial end of the lead screw 11. The bevel gear set 21 includes a first bevel gear 211 connecting to the rotating member 22 and a second bevel gear 212 connecting to one axial end of the lead screw 11. The first bevel gear 211 and the second bevel gear 212 are meshed together. One axial end of the lead screw 11 is connected to the drive mechanism and / or the second bevel gear 212 via the gear set 3. Normally, the drive mechanism and emergency mechanism 2 are located at opposite axial ends of the lead screw 11 to avoid transmission interference. For a more compact movement structure, the drive mechanism and emergency mechanism 2 are located at the same axial end of the lead screw 11, and the drive mechanism and / or emergency mechanism 2 are connected to the axial end of the lead screw 11 via the gear set 3 to solve the problem of transmission interference.

[0043] The first bevel gear 211 and the second bevel gear 212 mesh in the same plane or parallel plane as the transmission mechanism 1, so that the emergency mechanism 2 and the transmission mechanism 1 are in the same plane or parallel plane, avoiding the emergency mechanism 2 being set perpendicular to the transmission mechanism 1, thus ensuring that the movement has a small height. When the emergency mechanism 2 and the drive mechanism are respectively located at the two ends of the lead screw 11 along the axial direction, the output ends of the second bevel gear 212 and the drive mechanism can be nested and connected to the corresponding axial ends of the lead screw 11 to achieve the purpose of transmission. When the emergency mechanism 2 and the drive mechanism are located at the same end of the lead screw 11 along the axial direction, one of the output ends of the second bevel gear 212 and the drive mechanism can be nested with the axial end of the lead screw 11, and the other can be connected to the axial end of the lead screw 11 through the gear set 3; or both the emergency mechanism 2 and the drive mechanism can be connected to the axial end of the lead screw 11 through the gear set 3.

[0044] See Figure 4 , Figures 6-7 The gear set 3 includes a first gear 31, a second gear 32, and a third gear. The first gear 31 is connected to one axial end of the lead screw 11, the second gear 32 is connected to the second bevel gear 212, and the third gear is connected to the output end of the drive mechanism. The first gear 31 meshes with the corresponding second gear 32 and / or third gear. When the axial end of the lead screw 11 needs to be connected to the emergency mechanism 2 and the drive mechanism via the gear set 3, the lead screw 11 utilizes the meshing of the first gear 31 with the second gear 32 and the third gear to achieve a transmission connection with the second bevel gear 212 and the output end of the drive mechanism.

[0045] Based on the above structure, the transmission mechanism 1 further comprises a transmission base, the transmission base comprises a first fixed seat 13 and a second fixed seat 14 arranged at the axial two ends of the lead screw 11, the axial two ends of the lead screw 11 are rotatably arranged at the first fixed seat 13 and the second fixed seat 14 respectively, and the transmission mechanism 1 is in transmission connection with the emergency mechanism 2 and the driving mechanism. The transmission base plays a role of bearing the lead screw 11 without affecting the rotation of the lead screw 11, and can limit the rotation axis of the lead screw 11 to prevent rotation deviation.

[0046] In the utility model, the driving mechanism and the emergency mechanism 2 are arranged at the axial one end of the lead screw 11, the axial one end of the lead screw 11 is rotatably arranged at the first fixed seat 13 and connected with the first gear 31, the axial other end of the lead screw 11 is rotatably arranged in the second fixed seat 14, and the axial other end of the lead screw 11 is connected with the second fixed seat 14 through the buffer 15. The axial other end of the lead screw 11 penetrates into the second fixed seat 14 and abuts against the second fixed seat 14 through the buffer 15, which can move the buffer 15 relative to the second fixed seat 14 when the lead screw 11 is extruded by external force, buffer protection is carried out on the lead screw 11 by the buffer 15, the deformation and damage of the lead screw 11 when extruded by external force are reduced, and the buffer effect is provided for the flap 5 when the flap 5 is extruded by external force in the locked state. The buffer 15 can be a spring or a rubber part.

[0047] When the axial one end of the lead screw 11 is in transmission connection with the gear set 3 through the first fixed seat 13, the gear set 3 can be arranged outside the first fixed seat 13, so that the axial one end of the lead screw 11 is in transmission connection with the gear set 3 after penetrating through the first fixed seat 13, and the gear set 3 is in transmission connection with the corresponding emergency mechanism 2 and / or driving mechanism. Generally, the second umbrella gear 212 and the output end of the driving mechanism are selectively nested with the axial one end of the lead screw 11, and the other is in transmission connection through the gear set 3.

[0048] In the utility model, gear set 3 is established on first fixed seat 13, the axial one end of screw rod 11 is inserted into first fixed seat 13 to connect first gear 31, second bevel gear 212 is inserted into first fixed seat 13 through adapter shaft 23 to connect second gear 32, and the output end of driving mechanism is inserted into first fixed seat 13 to connect third gear. Driving mechanism includes motor, and motor and second bevel gear 212 all have certain size, when both are established on the axial same end of screw rod 11, in order to avoid transmission interference, motor and second bevel gear 212 are all drivenly connected with the axial one end of screw rod 11 through gear set 3. First fixed seat 13 is provided with installation groove for the rotation of gear set 3, and first gear 31, second gear 32 and third gear are sequentially meshed and connected in the installation groove, and the axial one end of screw rod 11, the output end of motor and adapter shaft 23 connected with second bevel gear 212 are all inserted into the installation groove of first fixed seat 13 to connect first gear 31, third gear and second gear 32 respectively, so that driving mechanism and emergency mechanism 2 are all drivenly connected with transmission mechanism 1 using gear set 3. And, gear set 3 is installed on first fixed seat 13, which can reduce the volume and occupied space of the movement.

[0049] Referring to Figures 5-7 Adapter shaft 23 is nestedly connected with second bevel gear 212 and is locked by clamp spring 26, protective sleeve 24 is provided outside bevel gear set 21 and the connecting part of bevel gear set 21 with screw rod 11 and rotating part 22, and bevel gear set 21 and protective sleeve 24 are connected by bearing 25. Adapter shaft 23 is nested into second bevel gear 212, and clamp spring 26 is clamped outside second bevel gear 212 and located at the connecting part of second bevel gear 212 and adapter shaft 23, so as to ensure the stability of the connection between second bevel gear 212 and adapter shaft 23. Protective sleeve 24 protects bevel gear set 21, but does not affect the rotation of bevel gear set 21, and is sealingly fixed on first fixed seat 13 to achieve waterproof effect. Bearing 25 is arranged between protective sleeve 24 and first bevel gear 211 and second bevel gear 212, which is conducive to ensuring the smooth transmission of first bevel gear 211 and second bevel gear 212.

[0050] In addition to the basic structure described above, the outer periphery of the lead screw 11 is sleeved with two elastic and retractable sealing sleeves 16 in the axial direction. The inner walls of the two sealing sleeves 16 are spaced apart from the outer wall of the lead screw 11. The nut 12 is arranged between the two sealing sleeves 16, and the axial ends of the nut 12 are respectively sealingly connected to one end of the corresponding sealing sleeve 16. The other ends of the two sealing sleeves 16 are respectively sealingly connected to the first fixed seat 13 and the second fixed seat 14. When the driving mechanism or emergency mechanism 2 drives the lead screw 11 to rotate through the gear set 3 to drive the nut 12 to reciprocate along the axial direction of the lead screw 11, the corresponding sealing sleeve 16 can be extruded, and the other sealing sleeve 16 can be elongated, so that the sealing sleeve 16 can always seal the lead screw 11, thereby achieving the effect of waterproofing.

[0051] Referring to Figure 3 and Figure 4 , the transmission mechanism 1 further comprises a guide plate 18 provided with a guide groove 181, and the nut 12 is adapted to the guide groove 181 and provided with a sliding block 121. The sliding block 121 and the guide groove 181 are in sliding fit to make the nut 12 slidingly connected with the guide plate 18, and the guide plate 18 limits the displacement of the nut 12 perpendicular to the sliding direction on the guide plate 18.

[0052] The guide plate 18 can be provided with one or two guide plates. The guide plate 18 is fixedly connected with the first fixed seat 13 and the second fixed seat 14 through the bolts 9 and / or the pins 10, which has a guiding effect to make the rotation of the lead screw 11 and the axial movement of the nut 12 along the guide plate 18, avoiding the deviation of the action. Moreover, the guide plate 18 has a moving protection and shock absorption effect. Based on the sliding connection relationship between the guide plate 18 and the nut 12, the guide plate 18 can assist the straight movement of the nut 12, and can also limit the displacement perpendicular to the direction when it is impacted by external force, so as to offset the external impact force, thereby protecting the nut 12 and avoiding deformation or damage. That is, during the axial movement of the nut 12 along the lead screw 11, the sliding block 121 is always abutted in the guide groove 181. In this way, the impact force received by the nut 12 can be transmitted to the sliding block 121, and then transmitted to the installation position by the guide plate 18, thereby achieving the effect of protecting the nut 12 and the lead screw 11.

[0053] The upper cover of the lead screw 11 and the nut 12 is provided with a protective cover 19, the two ends of the protective cover 19 are respectively fixed on the first fixed seat 13 and the second fixed seat 14, and the protective cover 19 is spaced apart from the lead screw 11 and the nut 12. The protective cover 19 plays a protective role for the lead screw 11 and the nut 12 to avoid being impacted by external force. The protective cover 19 is fixed on the first fixed seat 13 and the second fixed seat 14 through the bolts 9.

[0054] In addition, referring to Figures 1-4The control box 7 is arranged on the side of the flap 5, and the top end of the control box 7 is provided with a detachable cover 71. One end of the rotating member 22 is arranged below the control box 7, and the control mechanism is arranged in the control box 7 to electrically connect the driving mechanism. The transmission mechanism 1 is connected to the flap 5 through the connecting arm 6, and the two ends of the connecting arm 6 are rotatably connected to the nut 12 and the flap 5, respectively.

[0055] When the power is on and the driving mechanism is normal, the control mechanism in the control box 7 controls the driving mechanism to drive the screw rod 11 to rotate through the meshing of the third gear and the first gear 31, so as to drive the nut 12 to reciprocate along the axial direction of the screw rod 11, thereby driving the connecting arm 6 to move synchronously and rotate relative to the nut 12, so that the connecting arm 6 drives the flap 5 to rotate to the closed state or the open state, realizing the normal opening or closing of the parking lock, so as to achieve the purpose of locking or closing the lock. In the case of electric control failure, the emergency mechanism 2 can be used to operate the lock, that is, the cover 71 is removed, the rotating member 22 is manually rotated, and the nut 12 is driven to move along the axial direction of the screw rod 11 through the meshing of the umbrella gear set 21, the first gear 31 and the second gear 32, thereby driving the connecting arm 6 to move synchronously and rotate relative to the nut 12, so that the connecting arm 6 drives the flap 5 to rotate to the closed state to realize the closing of the parking lock, so that the car can leave in time.

[0056] Moreover, the emergency mechanism 2 and the transmission mechanism 1 are in the same plane or parallel plane, which can reduce the height of the movement core, reduce the space occupied by the movement core, and facilitate the selection of the installation position of the parking lock when the movement core is applied to the parking lock.

[0057] The nut 12 is provided with a connecting block 122 to rotatably connect the connecting arm 6, and the connecting block 122 is connected to one end of the sliding block 121 away from the guide plate 18, so that the structure of the nut 12 is more compact, and the impact force received by the flap 5 can be transferred by the guide plate 18 to prevent damage to the flap 5, the connecting arm 6 and the movement core. The number of connecting arms 6 can be one, two or more according to requirements.

[0058] The umbrella gear set 21 is connected to the rotating member 22 through the rocker 27, and the two ends of the rocker 27 are respectively nested with the umbrella gear set 21 and the rotating member 22, and the rocker 27 is locked between the umbrella gear set 21 through the snap spring 26. When the movement core is far away from the control box 7, the connection between the umbrella gear set 21 and the rotating member 22 can be realized through the rocker 27. One end of the rocker 27 is nested with the rotating member 22, and the rotating member 22 is fixedly inserted into one end of the rocker 27 to drive the rocker 27 to rotate when the rotating member 22 is rotated. The other end of the rocker 27 is inserted into the first umbrella gear 211 and locked through the snap spring 26, so as to ensure the stability of the connection between the first umbrella gear 211 and the rocker 27 and ensure the transmission effect.

[0059] In addition, the mounting base 4 is provided with a connecting seat 41, the flap 5 is rotationally connected with the connecting seat 41 through a main shaft 51, the connecting arm 6 is rotationally connected with the flap 5 through a connecting shaft 52, and the central axis of the main shaft 51 is offset from the central axis of the connecting shaft 52. The connecting seat 41 can be a hinge structure, which is arranged below the flap 5 and has a hidden effect. The main shaft 51 is arranged in the flap 5 and can be fixedly connected with the flap 5 or the connecting seat 41 to be rotationally connected with the connecting seat 41 or the flap 5, so as to realize rotation of the flap 5 relative to the mounting base 4. The connecting shaft 52 is arranged in the flap 5 and can be fixedly connected with the flap 5 or the connecting arm 6 to be rotationally connected with the connecting arm 6 or the flap 5, so as to realize rotational connection of the connecting arm 6 and the flap 5.

[0060] The central axes of the main shaft 51 and the connecting shaft 52 are offset, when the motor or the emergency mechanism 2 drives the screw rod 11 to rotate, the screw rod 11 drives the nut 12 to slide along the guide plate 18, and the connecting arm 6 slides along the nut 12 and rotates relative to the nut 12, the connecting arm 6 drives the flap 5 to flip around the main shaft 51 to the closed state or the open state, so that the motor can drive the flap 5 to flip with a small torque, and the movement range of the connecting arm 6 is small, which is beneficial to realize miniaturization design of the parking lock.

[0061] The flap 5 is provided with an accommodating groove 53 at a position where the flap 5 rotationally cooperates with the connecting arm 6, the connecting shaft 52 is arranged in the accommodating groove 53 and connected with the connecting arm 6, and the accommodating groove 53 extends along the arrangement direction of the connecting arm 6, so that the flap 5 avoids the connecting arm 6 during rotation. The accommodating groove 53 needs to ensure the connection between the connecting arm 6 and the connecting shaft 52, and also needs to provide enough space for the movement of the connecting arm 6, so as not to affect the complete closing of the flap 5.

[0062] The main shaft 51 is sleeved with a torsional spring 8, and the two ends of the torsional spring 8 are connected to the mounting base 4 and the flap 5 respectively. When the flap 5 is impacted, the flap 5 transmits the impact force to the main shaft 51, and the torsional spring 8 connected with the main shaft 51 can offset the impact force and balance the self-gravity of the flap 5, so as to prevent the flap 5 from being closed by impact.

[0063] When the parking lock is in the mounted state, the top surface of the flap 5 is flush with the surface of the installation environment to which the parking lock belongs. The parking lock can be installed in underground parking lots, ground parking lots, roadside parking spaces and the like, and through the arrangement that the top surface of the flap 5 is flush with the surface of the installation environment, the top surface of the installed parking lock is basically flush with the surface of the installation environment, so that the effect of being buried and hidden is achieved, and the parking lock is prevented from protruding from the surface of the installation environment and affecting traffic and being easily damaged.
