[0040] Referring to Figures 1 to 9 A flat parking space lock with overload protection function is shown, which comprises a lock seat 1;

[0041] The lock seat 1 is provided with a baffle 11, which is rotationally connected to the lock seat 1;

[0042] The lock seat 1 is also provided with a driving assembly 2 for driving the baffle 11 to swing relative to the lock seat 1;

[0043] The driving assembly 2 drives the baffle 11 through an overload protection assembly 3.

[0044] In some embodiments, the baffle 11 swings relative to the lock seat 1 within a range of 0 degrees to 90 degrees. When the included angle between the baffle 11 and the lock seat 1 is 90 degrees, the baffle 11 is in a raised state, at which time the parking space lock is in a locked state, and the vehicle cannot enter or leave the parking space.

[0045] When the included angle between the baffle 11 and the lock seat 1 is 0 degrees, the baffle 11 is in a flat state, at which time the parking space lock is in an unlocked state, and the vehicle can normally enter or leave the parking space.

[0046] In some embodiments, the overload protection assembly 3 comprises a sleeve 31 provided with an overload protection sheet 32, and the power output part 21 of the driving assembly 2 is connected to the sleeve 31 through the overload protection sheet 32.

[0047] In some embodiments, the power output part 21 can cooperate with the sleeve 31, that is, when the baffle 11 is impacted, the overload protection sheet 32 is damaged or deformed, at which time the power output part 21 can extend into the sleeve 31, so that the driving assembly 2 does not need to bear a large force when the baffle 11 is impacted.

[0048] It can be understood that the overload protection piece 32 is used to connect the sleeve 31 and the power output part 21. When the baffle 11 is impacted, the overload protection piece 32 is damaged, the connection between the power output part 21 and the sleeve 31 is invalid, and the sleeve 31 can move relative to the power output part 21, thereby realizing the overload protection function.

[0049] Therefore, the structure of the overload protection piece 32 can be any structure. The sleeve 31 and the power output part 21 can have a matching relationship or can not have a matching relationship, as long as the power output part 21 can move relative to the sleeve 31 after the overload protection piece 32 is damaged or deformed, and the overload protection function can be realized.

[0050] In some embodiments, the overload protection piece 32 is fixed to the sleeve 31, the power output part 21 is fixed to the overload protection piece 32, the overload protection piece 32 is provided with a notch 321 facilitating plastic deformation of the overload protection piece 32 when impacted, and the power output part 21 extends into the sleeve 31 through the deformed notch 321.

[0051] Referring to Figures 1 to 9 In some embodiments, the overload protection piece 32 can be fixed to the sleeve 31 in any manner. For example, the sleeve 31 can be provided with a first flange piece, the first flange piece is provided with a second flange piece, the first flange piece and the second flange piece are both provided with a through hole through which the power output part 21 can pass. The overload protection piece 32 can be fixed between the first flange piece and the second flange piece.

[0052] In some embodiments, the first flange piece and the second flange piece can be connected by bolts.

[0053] In some embodiments, the overload protection piece 32 is provided with a center hole 322, the notches 321 are uniformly distributed along the circumferential direction of the center hole 322, and the notches 321 are in communication with the overload protection piece 32.

[0054] In some embodiments, the overload protection piece 32 can also not be provided with the center hole 322. The ends of all notches 321 close to the center position of the overload protection piece 32 can be communicated.

[0055] In some embodiments, the overload protection piece 32 can also not be provided with the center hole 322 and the notches 321. The overload protection piece 32 can only be deformed or damaged when impacted. For example, the overload protection piece 32 can be made of a material with low strength, and in this case, the center hole 322 and the notches 321 do not need to be provided.

[0056] Referring to Figures 1 to 9As shown, in some embodiments, in order to facilitate the connection of the power output part 21 and the sleeve 31, the power output part 21 is provided with a pressure head 211, part of which is fixed in the center hole 322. The overload protection sheet 32 is fixed to the sleeve 31 through the first flange and the second flange. The pressure head 211 can be fixed to the power output part 21 through threads. For example, the pressure head 211 includes a head part with a diameter larger than that of the center hole 322 and a rod part with a diameter matching that of the center hole 322, an external thread is arranged on the rod part, and an internal thread is arranged on the power output part 21. The rod part passes through the center hole 322 and matches the internal thread, that is, the connection of the power output part 21 and the sleeve 31 is achieved.

[0057] In some embodiments, an elastic member 33 is arranged in the sleeve 31, which includes a fixed end and a movable end, the fixed end is fixed to the sleeve 31, and the movable end is in contact with the overload protection sheet 32, or the movable end is in contact with the power output part 21 through the center hole 322.

[0058] The elastic member 33 can be a spring or other component with elastic deformation function.

[0059] In some embodiments, after the baffle 11 is impacted, the overload protection sheet 32 is damaged, at this time, the power output part 21 enters the sleeve 31 through the overload protection sheet 32, at this time, the movable end can be directly in contact with the power output part 21, at this time, under the elastic force of the spring, the position of the sleeve 31 and the power output part 21 is still determined, and the baffle 11 is still in the locked state. However, since the connection of the power output part 21 and the sleeve 31 is realized by the spring, at this time, the baffle 11 can move, that is, the position of the power output part 21 relative to the sleeve 31 can be changed by overcoming the elastic force of the spring, and then the baffle 11 can swing.

[0060] In some embodiments, the driving assembly 2 is an electric push rod, which includes a rod seat 22 and a power output telescopic rod, and the power output part 21 is the telescopic rod.

[0061] In some embodiments, the electric push rod can be a waterproof electric push rod.

[0062] Referring to Figures 1 to 9 As shown, in some embodiments, the rod seat 22 is hinged to the lock seat 1, the sleeve 31 drives the baffle 11 through the connecting rod 13, the baffle 11 is rotationally connected to the lock seat 1 through the driving shaft 12, one end of the connecting rod 13 is rotationally connected to the sleeve 31, and the other end of the connecting rod 13 is fixed to the driving shaft 12.

[0063] In some embodiments, the connecting rod 13 and the sleeve 31 can be rotationally connected through a rotating shaft. In some embodiments, the connecting rod 13 and the sleeve 31 can be rotationally connected through a rotating shaft.

[0064] In some embodiments, the connecting rod 13 can be a connecting plate fixed to the driving shaft 12. The connecting plate can have two plates, and a fitting cavity is formed between the two plates. A part of the sleeve 31 is located in the fitting cavity, and the sleeve 31 can be rotatably connected to the connecting plate through a shaft body. The connecting plate can be an integral structure with the driving shaft 12.

[0065] In some embodiments, a rolling bearing can be arranged between the driving shaft 12 and the lock base 1. That is, the lock base 1 can be provided with a shaft hole matched with the driving shaft 12, and the rolling bearing is arranged between the driving shaft 12 and the shaft hole.

[0066] In some embodiments, the lock base 1 is provided with a power control box 14 at one end, and the driving assembly 2 and the overload protection assembly 3 are located in the power control box 14. The power control box can be fixed to the lock base 1 by screws.

[0067] In some embodiments, the lock base 1 is provided with a sensing control box 15 at the end opposite to the power control box 14. The sensing control box 15 is provided with a sensor for detecting a vehicle and a controller for controlling the driving assembly 2, and the sensor communicates with the controller. The sensing control box 15 can be fixed to the lock base 1 by screws.

[0068] The sensor and the controller are both conventional electronic elements in the prior art. The controller can be configured with a wireless communication function.

[0069] In some embodiments, the baffle 11 includes a plate body fixedly connected to the driving shaft 12, and the plate body is provided with a roller rotatably connected to the plate body. A nylon protective sleeve can be sleeved on the roller.

[0070] In some embodiments, the roller can be a steel shaft.

[0071] Referring to Figures 1 to 9 In some embodiments, when the baffle 11 is not lifted, the parking lock is in an unlocked state, and the electric push rod is in a fully retracted position. At this time, the vehicle wheels pass through the flat plate lock without any pressure load on the electric push rod. When the vehicle is parked in the parking space, it is detected that a vehicle is parked. After the vehicle is parked, the baffle 11 is lifted. According to the height of the vehicle chassis, a detection sensor can be added to the baffle 11. The detection sensor communicates with the controller. After the baffle 11 touches the vehicle chassis, the lifting is stopped and the baffle 11 retreats a small distance. At this time, the push rod remains.

[0072] When the vehicle is hard to stop in the parking space or the baffle 11 is impacted by external force, if the force is less than the safety force, the overload protection piece 32 is not deformed, and the parking lock is still in the locked state; when the external force is greater than the deformation force of the overload protection piece 32, the overload protection piece 32 is deformed, the telescopic rod of the electric push rod breaks through the overload protection piece 32, at this time, under the action of the spring in the sleeve 31, the spring is compressed by the telescopic rod, and the telescopic rod is still in the extended state to realize protection under the action of external force.

[0073] The force required for the overload protection piece 32 to be deformed is less than the force required when the telescopic rod and other components are damaged. After the overload protection piece 32 is damaged, the telescopic rod is retracted, and when the overload protection piece 32 is not broken, the pressure head 211 can still lower the baffle 11 in cooperation with the overload protection piece 32. The baffle 11 can still be raised when the telescopic rod is extended, at this time, since the overload protection piece 32 has been damaged, the parking lock does not have the locking function, but plays the elastic protection, if recovery is needed, a new overload protection piece 32 needs to be replaced, and the deformation force can be determined according to the material of the overload protection piece 32, the thickness of the overload protection piece 32 and the shape of the notch 321.

[0074] The above introduces the subject technical scheme of the utility model and corresponding details, and it can be understood that the above introduction is only some implementation of the subject technical scheme of the utility model, and some details can be omitted in specific implementation.

[0075] In addition, in some implementation of the utility model, multiple implementation can be combined, and various combination schemes are not listed one by one due to the length. The person skilled in the art can freely combine the above implementation according to the demand in specific implementation to obtain better application experience.

[0076] The person skilled in the art can obtain other detail configurations or drawings according to the subject technical scheme of the utility model and the drawings in the implementation of the subject technical scheme of the utility model, and obviously, these details still belong to the range covered by the subject technical scheme of the utility model without departing from the subject technical scheme of the utility model.
