Description

Technical Field

[0001] The utility model relates to the technical field of parking locks, in particular to a parking lock. Background Art

[0002] Parking locks are usually used for personal or parking lot parking space management to prevent parking spaces from being occupied. When a permitted vehicle approaches the parking space, the swing arm of the parking lock is lowered to allow the vehicle to enter the parking space; when the vehicle leaves the parking space, the swing arm of the parking lock stands up to prevent other vehicles from entering.

[0003] Existing parking locks generally include a bottom plate, a lock seat cover covering the bottom plate, a driving device, a transmission device located between the bottom plate and the lock seat cover, and swing arms rotatably arranged on both sides of the lock seat cover and drivingly connected to the output shaft of the transmission device. Since the driving device and the transmission device are directly located inside the bottom plate and the lock seat cover, the waterproof sealing effect is not good. In addition, the current swing arm does not have a self-locking function in the erected locked position or the self-locking solution is costly. Therefore, the swing arm can be stepped on and pushed down by hand in the erected locked position, and the purpose of self-locking and parking space management cannot be achieved. Again, most current parking locks only transmit and support on one side of the side rod and the output end of the transmission device, and the other side rod is simply fixed, resulting in a large deviation in the operation of the other side rod, large swing of the swing arm, and affecting the use of the parking lock.

[0060] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0061] It should be noted that the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "back", "side", "circumferential", etc. in the present invention indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the present invention. In addition, the terms such as "first" and "second" are only used to distinguish multiple components or structures with the same or similar structures, and do not represent a special limitation on the setting order or connection relationship.

[0062] Please refer to Figures 1 to 19 As shown in the figure, the embodiment of the present invention provides a parking lock 1000, which is used to be installed on a parking space (not shown in the figure) to manage the parking space. The parking lock 1000 includes: a bottom plate 100, a waterproof protection box 200, a driving device 300, a self - locking transmission device 400, a control device (not shown in the figure), a swing arm 600, a driven support centering device 700, and an anti - pressure protection device 800.

[0063] Among them, the bottom plate 100 is used for assembling various components and is fixed on the ground of the parking space during use. The waterproof protection box 200 is detachably arranged on the bottom plate 100 and is used for waterproof isolation of the components located therein. The driving device 300 is arranged in the waterproof protection box 200 and is used for providing power. The self-locking transmission device 400 is arranged in the waterproof protection box 200 and is in transmission connection with the driving device 300, so that the swing arm 600 has a self-locking function in the erected locking position. The control device is arranged in the waterproof protection box 200 and is electrically connected to the driving device 300; it is used to control the movement of the driving device 300. One side rod 611 of the swing arm 600 is detachably in transmission connection with the output end of the self-locking transmission device 400, and the other side rod 611 is detachably rotatably connected to the bottom plate 100 through the driven support centering device 700; it is used to be in an erected locking state or a lowered unlocking state under the drive of the self-locking transmission device 400. The anti-pressure protection device 800 includes a lock seat cover 810 and a blocking member 820. The lock seat cover 810 is covered on the bottom plate 100 to enclose and cover the waterproof protection box 200 therein; the blocking member 820 is detachably arranged outside the swing arm 600, so that at least part of the swing arm 600 can be located between the lock seat cover 810 and the blocking member 820 when the swing arm 600 is lowered; in this way, the components in the lock seat cover 810 and the swing arm 600 can be protected to avoid being damaged under the rolling action of the wheel.

[0064] Since the driving device 300, the self-locking transmission device 400 and the control device of the parking space lock 1000 are all arranged in the waterproof protection box 200 in the bottom plate 100 and the lock seat cover 810, the electric control part components of the parking space lock 1000 are not easily damaged due to the water ingress of the lock seat cover 810. In addition, since one side rod 611 of the swing arm 600 is in transmission connection with the output end of the self-locking transmission device 400, the swing arm 600 has a self-locking function in the locking position. Again, since the other side rod 611 of the swing arm 600 is rotatably connected to the bottom plate 100 through the driven support centering device 700, the operation of the swing arm 600 can be made more stable.

[0065] In order to make the swing arm 600 have a self-locking function both in the erected locking position and the lowered unlocking position, and to accurately position these two positions to accurately control the operation of the driving device 300. Optionally, please refer to Figure 3 , Figure 5 , Figures 9 to 17 , in this embodiment, the self-locking transmission device 400 includes a crank-rocker mechanism 410, a first sensing member 420 and a second sensing member 430.

[0066] Among them, the crank-rocker mechanism 410 includes a crank 411, a connecting rod 412, and a rocker 413. One end of the crank 411 is in transmission connection with the driving device 300, the other end of the crank 411 is hinged to the connecting rod 412, one end of the rocker 413 is hinged to the end of the connecting rod 412 far from the crank 411, and the other end of the rocker 413 is in transmission connection with a side rod 611 on one side of the swing arm 600.

[0067] The first sensing member 420 is arranged at the first extreme position where the rocker 413 swings, and is used to sense that the rocker 413 swings to the first extreme position, that is, the rocker 413 swings to one of the dead center positions; the second sensing member 430 is arranged at the second extreme position where the rocker 413 swings, and is used to sense that the rocker 413 swings to the second extreme position, that is, the rocker 413 swings to the other dead center position. The control device is electrically connected to the driving device 300, the first sensing member 420, and the second sensing member 430, and is used to control the operation of the driving device 300. Specifically, the control device is used to control the operation of the driving device 300 according to the sensing signals transmitted by the first sensing member 420 and the second sensing member 430.

[0068] It can be understood that when the rocker 413 swings to the first extreme position, the side rod 611 is correspondingly set to the unlocked state of being lowered, and when the rocker 413 swings to the second extreme position, the side rod 611 is correspondingly set to the locked state of being erected. In this way, the side rod 611 can have a self-locking function in both the lowered unlocked state and the erected locked state. And due to the existence of the first sensing member 420, the second sensing member 430, and the control device, the two extreme positions can be accurately positioned. Specifically, the control device can be an existing controller, so it will not be elaborated here. Specifically, the swing angle of the rocker 413 can be exactly [X] degrees by adjusting the lengths of the crank 411, the connecting rod 412, and the rocker 413 of the crank-rocker mechanism 410, so as to realize the swing of the side rod 611. Specifically, the length ratio of the crank 411, the connecting rod 412, and the rocker 413 is in the prior art, so it will not be elaborated here.

[0069] Optionally, please refer to Figure 17 , in this embodiment, both the first sensing member 420 and the second sensing member 430 are microswitches. Of course, in other embodiments, the first sensing member 420 and the second sensing member 430 can also be infrared sensors, ultrasonic sensors, or magnetic sensors. There is no specific limitation here, as long as they can accurately detect the swing arm 600 when the rocker 413 swings to the first extreme position and the second extreme position.

[0070] To avoid the external force being directly transmitted to the driving device 300 through the transmission device when the swing arm 600 is impacted by a large external force, which may cause the driving motor 310 in the driving device 300 to be overloaded and damaged, or cause the gears (not shown in the figure) in the speed reducer 320 of the driving device 300 to be damaged by tooth breakage. Optionally, please refer to Figure 3 , Figures 15 to 17 , in this embodiment, the driving device 300 and the self-locking transmission device 400 are drivingly connected through a transmission protection device 500. Optionally, the transmission protection device 500 includes: a slipping bushing 510 and a slipping shaft 520. The slipping bushing 510 is drivingly connected to the output shaft 321 of the driving device 300; the slipping shaft 520 is frictionally drivingly connected to the slipping bushing 510; specifically, the slipping shaft 520 is frictionally drivingly connected to the inner wall of the shaft hole e of the slipping bushing 510; one end of the slipping shaft 520 extending out of the slipping bushing 510 is drivingly connected to the crank 411; the slipping shaft 520 can idle relative to the slipping bushing 510 when the preset frictional force is exceeded.

[0071] In this way, during normal operation, the output shaft 321 of the driving device 300 transmits torque to the slipping bushing 510, the slipping bushing 510 transmits torque to the slipping shaft 520 through frictional drive, and the slipping shaft 520 transmits torque to the crank 411, thereby realizing the rotation of the swing arm 600 so that the swing arm 600 can be in the upright locked state or the lowered unlocked state. When the swing arm 600 is impacted by a large external force, the force transmitted by the swing arm 600 will cause the slipping shaft 520 to overcome the frictional force of the slipping bushing 510 and idle relative to the slipping bushing 510, so that the excessive external force cannot be directly transmitted to the driving device 300, and thus the driving device 300 will not be damaged, making the parking lock 1000 have the advantage of protecting the driving device 300 when the swing arm 600 is collided.

[0072] Optionally, please refer to Figure 16 and Figure 17, in this embodiment, the slipping bushing 510 includes a connecting section 511, a clamping section 512, and a clamping spring 513. The connecting section 511 is in transmission connection with the output shaft 321 of the driving device 300. Specifically, the output shaft 321 has a flat shaft portion 321a, and the connecting section 511 has a flat shaft groove f that matches the flat portion. The transmission connection between the connecting section 511 and the output shaft 321 of the driving device 300 is achieved through the fixed matching of the flat shaft portion 321a and the flat shaft groove f. It can be understood that the output shaft 321 can also be a key shaft, and the transmission connection between the connecting section 511 and the output shaft 321 of the driving device 300 is achieved by arranging a corresponding key groove in the connecting section 511, which is not specifically limited here. The clamping section 512 is cylindrical, and gaps g extending axially are circumferentially and spacedly arranged on the cylindrical wall of the clamping section 512. Specifically, the clamping section 512 is cylindrical, there is a transverse shaft hole e inside the cylindrical shape, and gaps g extending axially are evenly and spacedly arranged circumferentially on the cylindrical wall of the clamping section 512. The clamping spring 513 is sleeved on the outer periphery of the clamping section 512. By adjusting the clamping force of the clamping spring 513 on the outer periphery of the clamping section 512, the preset friction force of the sleeve on the slipping shaft 520 is set. That is, within the range of this preset friction force, the driving device 300 can normally transmit torque to the slipping shaft 520.

[0073] To achieve the high waterproof performance of the waterproof protection box 200, optionally, please refer to Figure 7 and Figure 8 , in this embodiment, the waterproof protection box 200 includes a waterproof box housing 210, a waterproof box top cover 220, and a first sealing ring 230. The waterproof box housing 210 is fixedly configured on the bottom plate 100. Specifically, the waterproof box housing 210 can be fixedly configured on the bottom plate 100 through a threaded fastener 240. The upper butt joint surface of the waterproof box housing 210 has a lower waterproof assembly groove a; the butt joint surface of the waterproof box top cover 220 has an upper waterproof assembly groove (not shown in the figure); the first sealing ring 230 is clamped between the lower waterproof assembly groove a of the waterproof box housing 210 and the upper waterproof assembly groove of the waterproof box top cover 220, and ribs 231 are provided on the upper side and / or the lower side of the first sealing ring 230. Specifically, the waterproof box housing 210 and the first sealing ring 230 clamp the first sealing ring 230 through a threaded fastener 240. Thus, the waterproof seal between the waterproof box housing 210 and the waterproof box top cover 220 is achieved.

[0074] To make the swing of the swing arm 600 smoother and improve the waterproof performance at the connection between the self-locking transmission device 400 and the swing arm 600 in the waterproof protection box 200. Optionally, please refer to Figure 6 , Figure 7 and Figure 14, in this embodiment, the parking lock 1000 further includes a first transmission shaft 910. One end of the first transmission shaft 910 is fixedly connected to the swing arm 600, and the other end is fixedly connected to the rocker 413. One side of the waterproof protection box 200 has a stepped shaft hole b, and the aperture of the outer shaft hole of the stepped shaft hole b is larger than that of the inner shaft hole. A second sealing ring 920, a second bearing 930, a third sealing ring 940, and a third bearing 950 are sequentially arranged in the stepped shaft hole b from outside to inside; the first transmission shaft 910 is rotationally connected to the waterproof protection box 200 in a sealed manner through the second sealing ring 920, the second bearing 930, the third sealing ring 940, and the third bearing 950. Since the aperture of the outer shaft hole of the stepped shaft hole b is larger than that of the inner shaft hole, even if there is accumulated water in the stepped shaft hole b, it will drain outwards. And using double bearings to support the first transmission shaft 910 can make the rotation of the first transmission shaft 910 more stable, and further make the swing of the swing arm 600 more stable. And using the second sealing ring 920 and the third sealing ring 940 for waterproof sealing on both sides of the second bearing 930 can further improve the waterproof performance of the waterproof protection box 200.

[0075] Optionally, please refer to Figure 7 , in this embodiment, the waterproof box housing 210 has a wire passing hole c; the waterproof protection box 200 includes a waterproof joint 250 tightly fitted in the wire passing hole c.
