Description

Technical Field

[0001] This utility model relates to the field of electric vehicle charging pile technology, specifically an electric vehicle charging pile with a ground lock structure. Background Technology

[0002] With the popularization of new energy vehicles, charging stations have become an indispensable supporting facility in daily life. Their core function is to provide electric power for electric vehicles, similar to a gas station for gasoline vehicles. By connecting to the vehicle's charging interface, they transmit electrical energy to the vehicle's battery, providing the necessary energy guarantee for vehicle operation.

[0003] A Chinese patent, CN120396739A, discloses an electric vehicle charging station with a ground lock structure. This station uses a first ground lock in the center of the parking space to block fuel-powered vehicles and a second ground lock near the road to block non-motorized vehicles. However, it still has the following problems: Firstly, it only relies on these two ground locks to block the main entry path of vehicles, without setting up an isolation barrier between adjacent charging stations. This allows electric vehicles, bicycles, and other non-motorized vehicles to pass through the gaps between adjacent charging stations into the charging space. Secondly, there are no corresponding limiting and blocking components on both sides of the parking and charging area. Even when the first and second ground locks are closed, some smaller non-motorized vehicles can still drive in and park from the edges of the parking space, ultimately occupying the charging space and affecting the normal parking and charging of new energy vehicles. Utility Model Content

[0004] The purpose of this utility model is to provide an electric vehicle charging pile with a ground lock structure to solve the problems of existing electric vehicle charging piles having no isolation barrier structure between adjacent charging piles, allowing non-motorized vehicles to pass through to the charging space; and the lack of limit and barrier components on both sides of the parking and charging area, allowing small non-motorized vehicles to still drive in and park from both sides of the parking space, occupying the charging space and affecting the normal use of new energy vehicles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric vehicle charging pile with a ground lock structure, comprising multiple bases arranged horizontally at intervals, a charging pile body disposed on the upper side of the bases, a fixed L-shaped barrier arm disposed on the same side of the multiple charging pile bodies, a connecting rod disposed at the end of the fixed L-shaped barrier arm and located on the side of the end charging pile body, a gear transmission flipping mechanism respectively mounted on one side of the multiple bases and one end of the connecting rod and located on the other side of the charging pile body, a flippable L-shaped barrier arm tractor connected to the output end of the gear transmission flipping mechanism, and multiple locking supports disposed on the other side of the bases away from the charging pile body and arranged horizontally at intervals; the lateral extension side of the fixed L-shaped barrier arm away from the charging pile body is fixedly connected to one side of the first locking support; the free ends of the multiple flippable L-shaped barrier arms respectively overlap the upper side of the corresponding locking supports; the fixed L-shaped barrier arm, the connecting rod and the multiple flippable L-shaped barrier arms enclose to form multiple parking charging areas arranged sequentially in the horizontal direction and corresponding one-to-one with the front of each charging pile body.

[0006] Furthermore, the gear transmission tilting mechanism includes a drive housing, a motor located outside the drive housing, a drive shaft coaxially connected to the motor output shaft, a driven shaft rotatably connected inside the drive housing and spaced parallel to the drive shaft, and gears respectively keyed to the outer walls of the drive shaft and the driven shaft; the two gears are meshed together; one end of the driven shaft extends out of the drive housing and is connected to the fixed end of the tilting L-shaped stop arm; the drive housing is connected to one side of the base or one end of the connecting rod.

[0007] Furthermore, the fixed L-shaped barrier arm includes a rear barrier extending horizontally along one side of multiple charging pile bodies, support columns respectively vertically disposed on the lower sides of both ends of the rear barrier, and a side barrier vertically disposed at one end of the rear barrier and extending away from the charging pile body at the front end; one end of the connecting barrier is vertically connected to the other end of the rear barrier and is located on one side of the charging pile body at the rear end.

[0008] Furthermore, the locking support includes a vertically arranged support column and an L-shaped groove opened at the upper end of the support column and facing the charging pile body; the free end of the flip-up L-shaped barrier arm overlaps in the L-shaped groove; and the free end of the side stop bar is connected to the top side of the first end support column.

[0009] Furthermore, a positioning protrusion is integrally formed at the corner of the flip-up L-shaped wheel stop; the positioning protrusion is adapted to be embedded in the L-shaped groove and its outer wall is in contact with the inner wall of the L-shaped groove, and the positioning protrusion is spaced apart from the free end of the adjacent flip-up L-shaped wheel stop.

[0010] Furthermore, high-definition license plate recognition cameras are respectively installed at the entrance of the parking charging area on the side of the multiple support columns away from the charging pile body, with the lens of the camera facing the direction of entry into the parking charging area; a PLC controller is installed on the outside of one of the drive housings; the multiple high-definition license plate recognition cameras and multiple motors are all electrically connected to the PLC controller.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model relates to an electric vehicle charging pile with a ground lock structure. By setting up a fixed L-shaped barrier arm, a connecting bar, multiple gear-driven flipping mechanisms, and multiple flip-type L-shaped barrier arms, the fixed L-shaped barrier arm, connecting bar, and multiple flip-type L-shaped barrier arms enclose a parking and charging area corresponding to each charging pile body.

Simultaneously, the enclosed parking and charging area, through the fixed connection between the lateral extension of the fixed L-shaped barrier arm and the locking support, and the overlapping support of the free end of the flip-type L-shaped barrier arm, constructs a complete limiting and blocking boundary on both sides of the parking area, preventing smaller non-motorized vehicles from entering and parking from the edges of the parking space. Ultimately, this solves the problem of illegal occupation of charging spaces, ensures the normal parking and charging of new energy vehicles, and improves the utilization efficiency and dedicated management effect of charging piles.

[0014] Please see Figure 1-4 An electric vehicle charging pile with a ground lock structure includes multiple horizontally spaced bases 1, a charging pile body 2 located on the upper side of the bases 1, a fixed L-shaped barrier arm 3 located on the same side of the multiple charging pile bodies 2, a connecting rod 7 located at the end of the fixed L-shaped barrier arm 3 and on one side of the charging pile body 2, a gear-driven flipping mechanism 5 respectively installed on one side of the multiple bases 1 and one end of the connecting rod 7 and located on the other side of the charging pile body 2, and a flip-able L-shaped barrier arm that is driven to the output end of the gear-driven flipping mechanism 5. The vehicle arm 6 and multiple locking supports 4 located on the other side of the base 1 away from the charging pile body 2 and horizontally spaced apart; the fixed L-shaped blocking arm 3 is fixedly connected to one side of the first locking support 4 on its lateral extension side away from the charging pile body 2; the free ends of multiple flip-out L-shaped blocking arms 6 are respectively attached to the upper side of the corresponding locking support 4; the fixed L-shaped blocking arm 3, the connecting bar 7 and the multiple flip-out L-shaped blocking arms 6 enclose and form multiple parking charging areas arranged in sequence along the horizontal direction and corresponding one-to-one with the front of each charging pile body 2.

[0015] This application further proposes that the gear transmission tilting mechanism 5 includes a drive housing 14, a motor 15 fixedly mounted on the outside of the drive housing 14 by bolts, a drive shaft 16 coaxially connected to the output shaft of the motor 15, a driven shaft 17 rotatably connected to the inside of the drive housing 14 by bearings and arranged parallel to and spaced apart from the drive shaft 16, and gears 18 respectively keyed to the outer walls of the drive shaft 16 and the driven shaft 17; the two gears 18 are meshed; one end of the driven shaft 17 extends out of the drive housing 14 and is connected to the fixed end of the tiltable L-shaped stop arm 6; the drive housing 14 is connected to one side of the base 1 or one end of the connecting rod 7.

[0016] The output shaft of the motor 15 is rigidly connected to one end of the drive shaft 16 via a coupling; the extended end of the driven shaft 17 is fixed to the fixed end of the reversible L-shaped stop arm 6 (the end near the gear transmission reversing mechanism 5) by welding or flange connection; at the same time, the drive housing 14 is rigidly fixed to one side of the base 1 or one end of the connecting rod 7 by bolts, depending on the installation position; the outer side of the drive housing 14 is fixed to the housing of the motor 15 by bolts or snap-fit ​​structure, and multiple heat dissipation holes are evenly opened on the side wall of the motor housing 15.

[0017] Specifically, the parallel spacing of the two meshing gears 18 can precisely control the transmission ratio and ensure that the reversible L-shaped stop arm 6 can be smoothly rotated at a preset angle; the opening and closing of the reversible L-shaped stop arm 6 is realized through the motor 15, the driving shaft 16, the driven shaft 17 and the two meshing gears 18.

[0018] This application further proposes that the fixed L-shaped barrier arm 3 includes a rear barrier arm 8 extending horizontally along one side of multiple charging pile bodies 2, support columns 9 respectively vertically fixed to the lower sides of both ends of the rear barrier arm 8, and a side barrier arm 10 vertically fixed to one end of the rear barrier arm 8 and extending away from the first charging pile body 2; one end of the connecting barrier arm 7 is vertically fixedly connected to the other end of the rear barrier arm 8, and after connection, the whole extends in an L-shape and is located on one side of the rear charging pile body 2, forming one side boundary of the parking charging area together with the rear barrier arm 8.

[0019] Among them, the rear stop bar 8 is horizontally arranged along the same side of multiple charging pile bodies 2. The rear stop bar 8 is connected to the side of each charging pile body 2 through a detachable structure, specifically by bolt connection (the rear stop bar 8 has pre-set bolt holes corresponding to the charging pile body 2, and the bolts are fixed through the holes). The connection position avoids the charging interface, heat dissipation holes and other functional areas of the charging pile body 2 to ensure that it does not affect the normal use of the charging pile. The lower ends of the two support columns 9 are connected to the ground (or installation foundation) to form vertical support for the rear stop bar 8.

[0020] Specifically, the side barrier 10 extends away from the charging pile body 2 at the first end, and can cooperate with the first locking support 4 to form the first boundary of the parking charging area, preventing vehicles from accidentally entering from the side; the vertical connection between the connecting barrier 7 and the rear barrier 8 forms the rear boundary, so that the fixed L-shaped barrier arm 3 and the connecting barrier 7 together enclose the fixed side boundary of the parking charging area, and combined with the movable boundary of the flip-up L-shaped barrier arm 6, the parking range of the vehicle can be limited.

[0021] This application further proposes that the locking support 4 includes a vertically arranged support column 11 and an L-shaped groove 12 opened at the upper end of the support column 11 and facing the charging pile body 2; the free end of the flip-up L-shaped barrier arm 6 is attached to the L-shaped groove 12; and the free end of the side stop bar 10 is connected to the top side of the first end support column 11.

[0022] Specifically, the support column 11 is vertically fixed to the ground (or the mounting base); the support column 11 and the L-shaped groove 12 can support the free end of the reversible L-shaped stop arm 6.

[0023] This application further proposes that a positioning protrusion 13 is integrally formed at the corner of the flip-up L-shaped wheel stop 6; the positioning protrusion 13 is adapted to be embedded in the L-shaped groove 12 and its outer wall is in contact with the inner wall of the L-shaped groove 12, and the positioning protrusion 13 is spaced apart from the free end of the adjacent flip-up L-shaped wheel stop 6.

[0024] Among them, the outer peripheral dimension of the positioning protrusion 13 is adapted to the inner wall dimension of the L-shaped groove 12 on the support column 11; at the same time, in the two adjacent flip-up L-shaped blocking arms 6, the positioning protrusion 13 of the first blocking arm and the free end of the second flip-up L-shaped blocking arm 6 maintain a preset distance, and the two do not contact or interfere with each other.

[0025] Specifically, the positioning protrusion 13 fits into the L-shaped groove 12, and the force is distributed through surface contact, which improves the stability of the flip-up L-shaped stop arm 6 when it is closed (preventing shaking or displacement).

[0026] This application further proposes that multiple support columns 11 are provided with high-definition license plate recognition cameras 19 on the side opposite to the charging pile body 2 at the entrance of the parking charging area, with the lens of the camera 19 facing the direction of driving into the parking charging area; a PLC controller 20 is provided on the outside of one of the drive housings 14; multiple high-definition license plate recognition cameras 19 and multiple motors 15 are all electrically connected to the PLC controller 20.

[0027] Among them, the PLC controller (20) has a built-in vehicle type recognition algorithm; multiple high-definition license plate recognition cameras 19 are connected to the signal input terminal of the PLC controller 20 through signal lines to realize real-time transmission of license plate image data; the control output terminals of multiple PLC controllers 20 are connected to the control interfaces of multiple motors 15 through wires to form a transmission path for control commands; at the same time, the PLC controller 20 is electrically connected to the power supply system of the charging pile body 2 to obtain working power, and the motors 15 are also connected to the power supply through independent lines.

[0028] Specifically, the directional installation of the high-definition license plate recognition camera 19 (with the lens facing the direction of entry) ensures the accuracy of license plate recognition and avoids misjudgment; the PLC controller 20, as the central hub, realizes centralized signal processing and independent control of the motor 15, which can ensure the independent management of a single parking charging area (such as opening only the flip-up L-shaped barrier arm 6 of the target area), effectively preventing non-new energy vehicles and irrelevant equipment from occupying the charging space, improving the dedicated utilization rate and management efficiency of the charging pile body 2, while reducing the cost of manual intervention.

[0029] Working process and principle: When a vehicle drives into the parking and charging area, the high-definition license plate recognition camera 19 on the corresponding support column 11 captures the license plate image in real time and transmits the signal to the PLC controller 20. After receiving the signal, the PLC controller performs recognition processing. If it is identified as an authorized vehicle (such as a new energy vehicle), the PLC controller 20 sends a start signal to the motor 15 of the corresponding gear transmission flipping mechanism 5. The motor 15 drives the active rotating shaft 16 to rotate, which in turn drives the driven rotating shaft 17 through two meshing gears 18. The rotating mechanism causes the flip-up L-shaped barrier arm 6 to flip upwards around the driven shaft axis, disengaging the positioning protrusion 13 at its corner from the L-shaped groove 12 of the support column 11, thus opening the parking and charging area for vehicles to enter. For non-new energy vehicles, the motor 15 remains stationary, and the free end of the flip-up L-shaped barrier arm 6 and the positioning protrusion 13 remain engaged within the L-shaped groove 12, forming a closed area together with the rear stop bar 8, support column 9, side stop bar 10, and connecting stop bar 7, preventing non-new energy vehicles, electric vehicles, and other unrelated vehicles from entering. After parking, the vehicle can be charged using the corresponding charging pile 2. After charging is complete and the vehicle leaves, the PLC controller 20 can control the motor 15 to reverse, causing the flip-up L-shaped barrier arm 6 to reset and close, achieving dedicated management for new energy vehicles.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
