Description

Technical Field

[0001] This utility model relates to the technical field of parking warning equipment for new energy charging stations, specifically a parking anti-collision warning device for new energy charging stations. Background Technology

[0002] New energy charging stations are currently the shared charging locations for new energy vehicles. The core equipment of these stations is the multi-level new energy charging piles installed behind each parking space. Currently, the anti-collision measures for charging piles at charging stations mainly rely on two backstops installed behind the parking space according to the wheel spacing to remind drivers to park. However, in the actual process of reversing or driving into a parking space, due to the different vehicle models and the different height and angle of the driver's line of sight, the angle and position of the vehicle entering the parking space depend entirely on the driver's experience. For some novice drivers, it is not possible to accurately judge the safe distance between the rear or front of the car and the charging pile. Once a misoperation occurs or the vehicle is not parked correctly, it is extremely easy to collide with the charging pile equipment behind the parking space, or scratch the side vehicle, or affect the normal parking of the side parking space.

[0003] Therefore, we propose a parking collision avoidance warning device for new energy charging stations. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a parking anti-collision warning device for new energy charging stations.

[0005] This utility model provides a parking anti-collision warning device for a new energy charging station, including a signal transmitting mechanism and two sets of target mechanisms. Specifically, each parking space is equipped with one signal transmitting mechanism and two target mechanisms. Two adjacent parking spaces can share one target mechanism. The signal transmitting mechanism can be powered by either a solar photovoltaic power generation panel combined with an energy storage battery or by a unified power supply from the charging station's power distribution cabinet, depending on actual needs.

[0006] Furthermore, in order to accurately monitor the vehicle's direction of travel while parking in the parking space using the signal transmitting mechanism in conjunction with two target mechanisms, the signal transmitting mechanism is erected vertically at the center of the rear end of the parking space. Two sets of target mechanisms are symmetrically installed on either side of the signal transmitting mechanism, with both sets positioned 1.2-1.5 meters from the rear end of the parking space. The signal transmitting mechanism includes a column assembly A and a signal generating component mounted on top of column assembly A. Each set of target mechanisms includes a column assembly B and a target component mounted on top of column assembly B. The signal generating component includes a fan-shaped support plate. Each of the top two sides of the fan-shaped support plate is equipped with a set of monitoring components, which are installed symmetrically. The monitoring components consist of a fan-shaped frame and several miniature through-beam photoelectric sensors, which are fixed at an angle of 8-12 degrees to each other. The target assembly includes a horizontal support beam and several reflectors installed on top of the horizontal support beam. The horizontal support beam is arranged in the same direction along the parking space and its length is not less than 1 meter. The number of reflectors is the same as the number of miniature through-beam photoelectric sensors. Each reflector corresponds to one miniature through-beam photoelectric sensor. In order to facilitate parking at night, a yellow warning reflector is also installed on the back of each reflector.

[0007] To enable adjacent parking spaces to share a single target mechanism, the reflectors employ a V-shaped double-mirror reflection design. Each reflector is perpendicular to the laser beam emitted by the corresponding miniature through-beam photoelectric sensor, allowing it to effectively reflect the laser back to the through-beam photoelectric sensor. By utilizing the sequence of signals detected by each miniature through-beam photoelectric sensor and the time interval, the current parking status of the vehicle can be clearly and accurately determined, thus ensuring that the miniature through-beam photoelectric sensor can effectively acquire the vehicle's parking posture signal.

[0008] A loudspeaker and a PLC processor are installed in the middle of the fan-shaped support plate. The signal output of each miniature through-beam photoelectric sensor is electrically connected to the PLC processor via a wire. The PLC processor is also electrically connected to the loudspeaker. The PLC processor also integrates a delay module circuit. The loudspeaker provides parking warnings to the driver by emitting a warning sound, reminding the driver that the vehicle is veering to the left, right, tilted, or rearward during parking, so that the driver can correct it in time. The PLC processor is the data processor of the entire device, used to process data such as the interval sequence of signals transmitted by each miniature through-beam photoelectric sensor in each monitoring component, so as to cooperate with the loudspeaker to emit various alarm voices.

[0009] To prevent the device from being overused and performing unnecessary monitoring actions when the parking space is vacant or the vehicle is already in place, the PLC processor is connected to the ground lock control terminal of the corresponding parking space in the charging station. When a new energy vehicle enters the station to charge, the warning device will automatically activate when the driver controls the ground lock of the parking space to open via scanning a code or a mini-program, achieving a parking collision warning effect. In addition, combined with the delay module circuit built into the PLC processor, the PLC processor will automatically shut down the signal transmitting mechanism if it does not receive a new signal within the corresponding time.

[0010] Furthermore, to facilitate the installation and adjustment of the signal transmitting mechanism and the target mechanism, the column assembly A and column assembly B have the same structure, and the column assembly B includes a base, an outer tube, and an adjusting tube; the outer tube is vertically fixed on the base, and the adjusting tube is slidably inserted into the outer tube. Both the adjusting tube and the outer tube have a vertically formed elongated slot in the middle, and a locking bolt for locking the adjusting tube in the position inside the outer tube is installed in the slot.

[0011] Furthermore, a sleeve seat is welded to the bottom of the fan-shaped support plate to facilitate the installation of the entire signal generating assembly onto the top of the column assembly A; a rainproof umbrella cover is also installed on the top of the fan-shaped support plate to protect the electronic components inside the signal generating assembly.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model mainly consists of a signal transmitting mechanism and a target mechanism. Each parking space is equipped with one signal transmitting mechanism and two target mechanisms. Two adjacent parking spaces share one target mechanism. The signal transmitting mechanism is installed at the middle of the rear end of the parking space. The two target mechanisms in the same parking space are symmetrically installed on both sides of the signal transmitting mechanism. Using several through-beam photoelectric sensors distributed at a fan-shaped angle, in conjunction with multiple reflectors correspondingly set on the two target mechanisms, during the parking process, the through-beam photoelectric sensors set at different angles on both sides can effectively provide real-time warnings to the driver regarding the vehicle's position on the left or right side of the parking space and the safe distance between the vehicle and the rear of the parking space. This achieves the safety and anti-collision warning function for new energy vehicles entering the parking station. Attached Figure Description

That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0020] Example:

[0021] like Figure 1-3 As shown, the present invention provides a parking anti-collision warning device for a new energy charging station, including a signal transmitting mechanism 1 and two sets of target mechanisms 2. Specifically, each parking space is equipped with one signal transmitting mechanism 1 and two target mechanisms 2. Two adjacent parking spaces can share one target mechanism 2. The signal transmitting mechanism 1 can be powered by either a solar photovoltaic power generation panel combined with an energy storage battery or by a unified power supply from the charging station distribution cabinet, depending on actual needs.

[0022] To accurately monitor the vehicle's direction of travel while parked in a parking space using the signal transmitting mechanism 1 in conjunction with two target mechanisms 2, the signal transmitting mechanism 1 is erected vertically at the center of the rear end of the parking space. The two target mechanisms 2 are symmetrically installed on either side of the signal transmitting mechanism 1, with each set positioned 1.2-1.5 meters from the rear end of the parking space. The signal transmitting mechanism 1 includes a column assembly A101 and a signal generating component 102 mounted on top of the column assembly A101. Each target mechanism 2 includes a column assembly B201 and a target component 202 mounted on top of the column assembly B201. The signal generating component 102 includes a fan-shaped support plate 121, with each fan-shaped support plate 121 having a target component 202 mounted on either side of its top. A set of monitoring components is installed, with two sets of monitoring components installed symmetrically. The monitoring components consist of a fan-shaped frame 123 and several miniature through-beam photoelectric sensors 124, which are installed and fixed at an angle of 8-12 degrees to each other. The target component 202 includes a horizontal support beam 221 and several reflectors 222 installed on the top of the horizontal support beam 221. The horizontal support beam 221 is arranged in the same direction along the parking space, and the length of the horizontal support beam 221 is not less than 1 meter. The number of reflectors 222 is the same as the number of miniature through-beam photoelectric sensors 124. Each reflector 222 corresponds to one miniature through-beam photoelectric sensor 124. In order to facilitate parking at night, a yellow warning reflector 223 is also installed on the back of each reflector 222.

[0023] To enable adjacent parking spaces to share a single target mechanism 2, its reflector 222 adopts a V-shaped double-mirror reflection design. The mirror surface of each reflector 222 is designed to be perpendicular to the laser beam emitted by the corresponding miniature through-beam photoelectric sensor 124, so that it can effectively reflect the laser emitted by the through-beam photoelectric sensor. By utilizing the sequence of signals detected by each miniature through-beam photoelectric sensor 124, the current parking status of the vehicle can be clearly and accurately determined, thereby ensuring that the miniature through-beam photoelectric sensor 124 can effectively acquire the vehicle parking posture signal.

[0024] A loudspeaker 125 and a PLC processor 126 are installed in the middle of the fan-shaped plate 121. The signal output terminal of each miniature through-beam photoelectric sensor 124 is electrically connected to the PLC processor 126 through wires 127. The PLC processor 126 is electrically connected to the loudspeaker 125. The PLC processor 126 also integrates a delay module circuit. The function of the loudspeaker 125 is to provide parking warning to the driver by emitting a warning sound, reminding the driver that the vehicle body is leaning to the left, right, tilted, or rearward during parking, so that the driver can correct it in time. The PLC processor 126 is the data processor of the entire device. It is used to process data such as the interval sequence of the signals transmitted by each miniature through-beam photoelectric sensor 124 in each monitoring component, so as to cooperate with the loudspeaker 125 to emit various alarm voices.

[0025] To prevent the device from being overused and performing unnecessary monitoring actions when the parking space is vacant or the vehicle is already in place, the PLC processor 126 is connected to the ground lock control terminal of the corresponding parking space in the charging station. When a new energy vehicle enters the station to charge, the warning device will automatically activate when the driver controls the ground lock of the parking space to open by scanning a code or using a mini-program, thus achieving a parking anti-collision warning effect. In addition, combined with the delay module circuit built into the PLC processor 126, when the PLC processor 126 in the signal transmitting mechanism 1 does not receive a new signal within the corresponding time, the PLC processor 126 will automatically shut down the signal transmitting mechanism 1.

[0026] To facilitate the installation and adjustment of the signal transmitting mechanism 1 and the target mechanism 2, their column assembly A101 and column assembly B201 have the same structure. The column assembly B201 includes a base 211, an outer tube 212 and an adjusting tube 213. The outer tube 212 is vertically fixed on the base 211, and the adjusting tube 213 is slidably inserted into the outer tube 212. Both the adjusting tube 213 and the outer tube 212 have a vertically formed elongated slot 214 in the middle. A locking bolt 215 for locking the adjusting tube 213 in the position inside the outer tube 212 is installed in the slot 214.

[0027] A sleeve seat 122 is welded to the bottom of the fan-shaped support plate 121 to facilitate the installation of the entire signal generating assembly 102 onto the top of the column assembly A101; a rain cover 128 is also installed on the top of the fan-shaped support plate 121 to protect the electronic components inside the signal generating assembly 102.
