Description

Technical Field

[0001] This invention relates to the field of new energy vehicle charging equipment technology, specifically a charging pile system with a hoisting and lifting parking space lock. Background Technology

[0002] A charging pile system is a power supply system for charging new energy vehicles. It is usually installed in a parking space. The charging pile system also includes a parking space lock installed in the parking space to prevent the parking space where the charging pile is located from being occupied by non-charging vehicles.

[0003] Common parking locks include the "parking lock" in Chinese Patent Publication No. CN103669947A and the "a parking lock" in Chinese Patent Publication No. CN105464434B. The above-mentioned parking locks are usually installed on the ground. When the parking lock is raised, it prevents non-charging vehicles from entering the parking space where the charging station is located.

[0004] While the aforementioned parking locks can provide some obstruction, their shortcomings include the fact that if a non-charging vehicle enters the parking space of the charging station system after the lock is lowered, but then does not perform any charging operations (e.g., does not connect the charging gun to the vehicle), the charging station system is still occupied by a non-charging vehicle. This prevents vehicles that actually need charging from using the charging station system. To solve this problem, we propose a charging station system with a lifting and lowering parking lock. Summary of the Invention

[0005] The purpose of this invention is to provide a charging pile system with a hoisting and lifting parking space lock to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A charging pile system with a lifting and lowering parking space lock includes a charging pile installed on a parking space and a support frame. An occupancy removal mechanism is installed on the support frame, and the occupancy removal mechanism includes:

[0008] The removal assembly includes a base plate unit with one end hinged to the bottom of a support frame, and a sliding plate unit slidably mounted on the base plate unit, the sliding plate unit being able to move the vehicle away from the parking space when the base plate unit tilts.

[0009] The drive assembly includes a take-up roller mounted on top of a support frame. The take-up roller is connected to the other end of a base plate unit via a first connecting rope and to the end of a slide plate unit via a second connecting rope. The first connecting rope and the second connecting rope are wound in opposite directions on the take-up roller.

[0010] Preferably, the support frame includes a base frame that covers the parking space, a top frame that is flush with the top of the base frame, and multiple support columns that connect and fix the top frame to the base frame.

[0011] Preferably, the base plate unit includes a support plate adapted to the base frame, one end of the support plate is fixed with a shaft post, and both ends of the shaft post are rotatably inserted into the inner wall of the base frame.

[0012] Preferably, the skateboard unit includes a frame plate, a set of movable wheels is installed at the bottom of the frame plate, and a set of support rollers is installed at the top of the frame plate.

[0013] Preferably, the movable wheel set and the support roller set are connected by a transmission assembly. When the movable wheel set rotates in the forward direction, the support roller set is in a locked state. When the movable wheel set rotates in the reverse direction, the support roller set is in a forward rotation state. When the movable wheel set is stationary, the support roller set can deflect in the forward direction.

[0014] Preferably, the transmission assembly includes a rack, one end of which is coaxially fixed with a second worm gear, a first worm wheel is slidably engaged on the rack, the first worm wheel is driven by a first worm gear receiving a moving wheel set, and the second worm gear is driven by a second worm wheel receiving a support roller set.

[0015] Preferably, the first worm gear includes a worm gear ring, and the inner wall surface of the worm gear ring is movably hinged with a plurality of ratchet units, each of which can engage with the rack when the moving wheel set rotates in the opposite direction.

[0016] Preferably, the gear and the second worm constitute a shaft structure, and a blind hole is provided on the inner wall of the frame plate for the two ends of the shaft structure to be inserted. A spring is fixed at the bottom of the blind hole, and a washer is fixed at the end of the spring near the shaft structure.

[0017] Preferably, the first worm gear is rotatably connected to the frame plate, the movable wheel set includes a roller fixed coaxially with the first worm gear, and the movable wheel set also includes an auxiliary wheel installed at the bottom of the frame plate.

[0018] Preferably, the take-up roller body is composed of a first winding roller that is wound and fixed to the first connecting rope and a second winding roller that is wound and fixed to the second connecting rope, and a drive motor mounted on a support frame is fixed on the axis of the take-up roller.

[0019] In the above technical solution, the present invention provides a charging pile system with a hoisting and lifting parking space lock. By installing a support frame with a de-occupancy mechanism on a parking space with a charging pile, the non-charging vehicle occupying the parking space can be removed from the parking space under the action of the removal component and the drive component, thereby preventing the charging pile system from being occupied by non-charging vehicles, so that vehicles that really need to charge can use the charging pile system normally.

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Please see Figure 1-6 The present invention provides a charging pile system with a lifting and lowering parking space lock, including a charging pile 1 installed on a parking space and a support frame 2. The support frame 2 is equipped with an occupancy mechanism, which includes:

[0031] The removal assembly 3 includes a base plate unit 3.1 with one end hinged to the bottom of the support frame 2. A sliding plate unit 3.2 is slidably mounted on the base plate unit 3.1. When the base plate unit 3.1 tilts, the sliding plate unit 3.2 can drive the vehicle out of the parking space.

[0032] The drive assembly 5 includes a take-up roller 5.1 mounted on the top of the support frame 2. The take-up roller 5.1 is connected to the other end of the base plate unit 3.1 via a first connecting rope 5.3. The take-up roller 5.1 is connected to the end of the slide plate unit 3.2 via a second connecting rope 5.4. The first connecting rope 5.3 and the second connecting rope 5.4 have opposite winding and unwinding states on the take-up roller 5.1.

[0033] Specifically, the charging pile 1 is electrically connected to a charging gun, the support frame 2 is a frame cage structure, the base plate unit 3.1 has an inclined state and a horizontal state, the base plate unit 3.1 can tilt in the direction of the outside of the support frame 2 in the inclined state, the origin of the tilting deflection of the sliding plate unit 3.2 is located on the bottom edge of the support frame 2, the winding roller 5.1 can rotate in the forward direction and in the reverse direction, the support frame 2 is equipped with a position sensor 6 to detect whether the vehicle is in the parking space, and the drive component 5 has a processing unit that receives charging feedback from the charging pile 1 and signals from the position sensor 6;

[0034] In actual use, under normal conditions, the base plate unit 3.1 is in a horizontal state parallel to the ground. When the charging pile 1 has no power output and the position sensor 6 does not detect a vehicle, the winding roller 5.1 is stationary. When the charging pile 1 has no power output and the position sensor 6 has detected a vehicle, after a predetermined time period, the winding roller 5.1 rotates in the forward direction, causing the base plate unit 3.1 to tilt. When the charging pile 1 has power output and the position sensor 6 has detected a vehicle, the winding roller 5.1 is stationary.

[0035] For example, when a vehicle can normally drive into the space of the support frame 2 in the parking space, the vehicle is located on the horizontal base unit 3.1, and the vehicle's wheels are in contact with the sliding plate unit 3.2 on the base unit 3.1. If the vehicle has been parked for more than a preset time without charging, such as if the charging gun has not been electrically connected to the vehicle after ten or fifteen minutes, it is determined that the vehicle is occupying the parking space. At this time, the take-up roller 5.1 rotates in the forward direction, the base unit 3.1 tilts, and the sliding plate unit 3.2 can drive the vehicle out of the parking space under the action of gravity. In other words, by installing a support frame with a de-occupancy mechanism in the parking space with a charging pile, the non-charging vehicle occupying the parking space can be removed from the parking space under the action of the removal component and the drive component, thereby preventing the charging pile system from being occupied by non-charging vehicles, so that vehicles that really need to charge can use the charging pile system normally.

[0036] In another embodiment of the present invention, the support frame 2 includes a base frame 2.1 that is framed over the parking space. The end of the base frame 2.1 facing the driving direction is an open end. A top frame 2.2 is provided flush with the top of the base frame 2.1. Multiple support columns 2.3 are connected and fixed between the top frame 2.2 and the base frame 2.1. The axis of each support column 2.3 is perpendicular to the horizontal plane. An elastic sleeve 2.4 and a reflective warning sign 2.5 are fixed on the support column 2.3. The elastic sleeve 2.4 can rotate on the support column 2.3, thereby reducing the degree of scratches when the vehicle collides with the support column 2.3.

[0037] In another embodiment of the present invention, the base plate unit 3.1 includes a lifting plate 3.11 adapted to the base frame 2.1. The lifting plate 3.11 is a rigid plate, and a shaft post 3.12 is fixed to one end of the lifting plate 3.11. The two ends of the shaft post 3.12 are rotatably inserted into the inner wall of the frame of the base frame 2.1. The axis of the shaft post 3.12 is parallel to the horizontal plane and perpendicular to the inner wall of the frame. The lifting plate 3.11 can tilt around the shaft post 3.12 as the center, so that the base plate unit 3.1 is in an inclined state. Preferably, the top of the lifting plate 3.11 is provided with a slide groove 3.13 for the sliding plate unit 3.2 to move.

[0038] In another embodiment of the present invention, the skateboard unit 3.2 includes a frame plate 3.21, which can slide within the slide groove 3.13. A set of movable wheels 3.22 is installed at the bottom of the frame plate 3.21, which can support the frame plate 3.21 to move on the support plate 3.11 and the ground. The set of movable wheels 3.22 consists of multiple movable wheels. A set of support rollers 3.23 is installed at the top of the frame plate 3.21, which consists of multiple support rollers. The support rollers are synchronously connected through the same transmission chain. The set of support rollers 3.23 can support the vehicle wheels on the skateboard unit 3.2. The axis of the movable wheel set 3.22 and the axis of the support roller set 3.23 are parallel to the axis of the axle column 3.12.

[0039] The movable wheel assembly 3.22 and the support roller assembly 3.23 are connected by a four-phase transmission component. When the movable wheel assembly 3.22 rotates in the forward direction, the support roller assembly 3.23 is in a locked state; when the movable wheel assembly 3.22 rotates in the reverse direction, the support roller assembly 3.23 is in a forward rotation state; when the movable wheel assembly 3.22 is stationary, the support roller assembly 3.23 can deflect in the forward direction. In other words, the support roller assembly 3.23 has a locked state and a forward rotation state. When the support roller assembly 3.23 is in the locked state, the roller does not deflect in any direction, and the vehicle can move synchronously with the frame plate 3.21. When the support roller assembly 3.23 rotates in the forward direction, it drives the vehicle to move on the frame plate 3.21, thereby disengaging the vehicle from the frame plate 3.21 and unloading the vehicle.

[0040] Specifically, the transmission assembly 4 includes a rack 4.1, one end of which is coaxially fixed with a second worm 4.2. The axis of the rack 4.1 is parallel to the horizontal plane, and the direction of the axis of the rack 4.1 is perpendicular to the axis of the shaft column 3.12. A first worm wheel 4.3 is slidably engaged on the rack 4.1. A first worm 4.4 driven by the moving wheel set 3.22 is engaged on the first worm wheel 4.3. The axis of the first worm 4.4 is parallel to the axis of the shaft column 3.12. A second worm wheel 4.5 driven by the support roller set 3.23 is engaged on the second worm 4.2. The second worm wheel 4.5 is coaxially fixed with the roller shaft of the support roller set 3.23.

[0041] Furthermore, the first worm gear 4.3 includes a worm gear ring 4.31, and multiple ratchet units 4.32 are movably hinged to the inner wall surface of the worm gear ring 4.31. Each ratchet unit 4.32 can engage with the rack 4.1 for transmission when the moving wheel assembly 3.22 rotates in the opposite direction. The ratchet unit 4.32 includes multiple ratchet plates 4.321 that are movably hinged to the inner wall surface of the worm gear ring 4.31. The surface of each ratchet plate 4.321 is perpendicular to the ring opening surface of the worm gear ring 4.31. The surface of each ratchet plate 4.321 is connected to the inner ring wall surface of the worm gear ring 4.31 by a torsion spring 4.322. In its natural state, the surface of each ratchet plate 4.321 is parallel to the radial line of the worm gear ring 4.31, that is, the ratchet plates 4.321 are all oriented towards the center position of the worm gear ring 4.31, so that the first worm gear 4.3 has a driving effect similar to a one-way ratchet on the rack 4.1.

[0042] Furthermore, the rack 4.1 and the second worm gear 4.2 constitute a shaft structure. The inner wall of the frame plate 3.21 has blind holes 4.6 for the two ends of the shaft structure to be inserted. A spring 4.7 is fixed at the bottom of the blind hole 4.6. A washer 4.8 is fixed at the end of the spring 4.7 near the shaft structure. Further, an annular groove 7 is provided on the inner wall of the blind hole 4.6. A vertical rod 8 is movably hinged to the side of the end of the shaft structure that extends into the blind hole 4.6. The vertical rod 8 always remains perpendicular to the horizontal plane under the action of natural gravity. A horizontal block 9 is vertically fixed at the end of the vertical rod 8. The vertical rod 8 and the horizontal block 9 form an L-shaped structure. When the angle between the vertical rod 8 and the shaft structure is not perpendicular, the horizontal block 9 can engage with the annular groove 7. When the horizontal block 9 engages with the annular groove 7, the shaft structure cannot move upward along the axis of the blind hole 4.6.

[0043] In actual use, when the base plate unit 3.1 is in an inclined state, under the action of gravity, the frame plate 3.21 slides down the lifting plate 3.11 along the slide groove 3.13 with the support of the moving wheel set 3.22. During the sliding process, the rotation of the moving wheel set 3.22 is positive, and the support roller set 3.23 is in a locked state. At this time, the vehicle detaches from the lifting plate 3.11 together with the frame plate 3.21, so the frame plate 3.21 continues to slide on the ground through the moving wheel set 3.22, and the rotation of the moving wheel set 3.22 continues to be positive.

[0044] When the frame plate 3.21 is pulled and limited by the second connecting rope 5.4, the frame plate 3.21 stops moving and the moving wheel set 3.22 stops rotating and is stationary. At this time, the vehicle has a tendency to continue moving under the action of inertia, which drives the support roller set 3.23 to be positively deflected, thereby reducing the frictional resistance of the vehicle to detach from the frame plate 3.21, so that the vehicle can detach from the frame plate 3.21 by means of inertial force.

[0045] When the frame plate 3.21 is pulled by the second connecting rope 5.4, it moves back into the support frame 2 in the opposite direction to the sliding direction. The rotating wheel set 3.22 rotates in the opposite direction. When the rotating wheel set 3.22 rotates in the opposite direction, the support roller set 3.23 is driven by the transmission assembly 4. Specifically, the reverse-rotating rotating wheel set 3.22 causes the first worm gear 4.4 to drive the first worm wheel 4.3 to rotate. The first worm wheel 4.3, through the ratchet unit 4.32, causes the rack 4.1 to rotate, which in turn causes the second worm gear 4.2, which is coaxially fixed with the rack 4.1, to drive the second worm wheel 4.5 to rotate. The second worm gear 4.5 is coaxially fixed with the support roller group 3.23, so that the support roller group 3.23 is in a forward rotation state, thereby continuing to provide assistance for the vehicle to detach from the frame plate 3.21 until the vehicle is completely detached from the frame plate 3.21, then the frame plate 3.21 also returns to the lifting plate 3.11, thus completing the transfer of the occupied vehicle from the parking space to the outside of the parking space;

[0046] It should be noted that when the frame plate 3.21 slides down on the base plate unit 3.1, the cross block 9 is engaged with the annular groove 7, and the shaft structure cannot move upward along the blind hole 4.6. Consequently, the second worm wheel 4.5, which is engaged with the second worm 4.2, cannot roll relative to the second worm 4.2. Therefore, the moving wheel set 3.22 is locked and cannot rotate, and the vehicle can move synchronously with the frame plate 3.21. When the frame plate 3.21 moves on a horizontal surface, the cross block 9 is separated from the annular groove 7, so the vehicle can detach from the frame plate 3.21 by inertia.

[0047] In another embodiment of the present invention, the rod body of the first worm gear 4.4 is rotatably connected to the frame plate 3.21. The movable wheel set 3.22 includes a roller 3.221 coaxially fixed with the first worm gear 4.4. The movable wheel set 3.22 also includes an auxiliary wheel 3.222 installed at the bottom of the frame plate 3.21, thereby increasing the support area at the bottom of the frame plate 3.21 and maintaining good stability of the frame plate 3.21.

[0048] In another embodiment of the present invention, the take-up roller 5.1 is composed of a first winding roller 5.11 fixedly wound with a first connecting rope 5.3 and a second winding roller 5.12 fixedly wound with a second connecting rope 5.4. A drive motor 5.2 mounted on a support frame 2 is fixedly mounted on the axis of the take-up roller 5.1. The axis of the take-up roller 5.1 is parallel to the axis of the shaft column 3.12. The first winding roller 5.11 and the second winding roller 5.12 are coaxially fixed. The diameter of the first winding roller 5.11 is smaller than the diameter of the second winding roller 5.12. The winding direction of the first connecting rope 5.3 on the first winding roller 5.11 is opposite to the winding direction of the second connecting rope 5.4 on the second winding roller 5.12. The first connecting rope 5.3 is connected to the end of the lifting plate 3.11 away from the shaft column 3.12. The second connecting rope 5.4 is connected to the frame plate 3.21.

[0049] In actual use, when the position sensor 6 has detected the vehicle and the predetermined time has elapsed, the take-up roller 5.1 rotates in the forward direction. At this time, the first winding roller 5.11 winds up the first connecting rope 5.3, causing the lifting plate 3.11 to be lifted and tilted around the shaft column 3.12. At the same time, the second connecting rope 5.4 on the second winding roller 5.12 is released, causing the base plate unit 3.1 to tilt and slip.

[0050] When the take-up roller 5.1 rotates in the opposite direction, the first winding roller 5.11 releases the first connecting rope 5.3, causing the lifting plate 3.11 to deflect back around the shaft 3.12. At the same time, the second connecting rope 5.4 on the second winding roller 5.12 is wound up, and the frame plate 3.21 moves back into the support frame 2 under the pull of the second connecting rope 5.4 until the lifting plate 3.11 returns to a horizontal state. At this time, the frame plate 3.21 also returns to the lifting plate 3.11.

[0051] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
