Description

Technical Field

[0001] The present invention relates to the technical field of charging pile expansion equipment, and in particular to a charging pile with a distance reminder structure. Background Art

[0002] With the popularization of new energy vehicles, charging vehicles has become a very common daily behavior. In order to adapt to the explosive growth in the number of new energy vehicles, the construction of charging piles is also gradually expanding. When a car needs to be charged, drive the car around the charging pile, and then remove the charging interface on the charging pile to charge the car. However, since the charging pile is usually fixed at the charging point, when the car drives to the front of the charging pile and reverses to gradually approach the charging pile, since the charging pile is located directly behind the car, the rearview mirrors on both sides of the car body cannot observe the specific position of the charging pile, and thus cannot control the distance from the car body to the charging pile.

[0003] In the prior art, the above-mentioned problem is usually observed through the reversing image carried by the car body itself, or by installing a light sensor for monitoring the distance on the front side of the charging pile. When the light sensor detects that the car body is too close to the charging pile, an alarm will be sounded. However, when the light is not sufficient at night, the car can only manually judge the distance through the coordination of the reversing lights and the reversing effect, which is very inconvenient. At the same time, if it rains, the light sensor will be blocked, thereby affecting the sound of the alarm, causing the car body to collide with the charging pile. In addition, on rainy days, the exposed charging connector will be eroded by rain, thereby reducing the service life.

[0004] In order to solve the above problems, there is an urgent need for a charging pile that is convenient for the driver to observe and does not rely on light sensors. Now a charging pile with a distance reminder structure is proposed. Summary of the invention

[0005] In view of the above problems, the present invention provides a charging pile with a distance reminder structure, which solves the problem in the prior art that the distance is usually observed through the reversing image carried by the car body itself, or by installing a light sensor for monitoring the distance on the front side of the charging pile. When the light sensor detects that the car body is too close to the charging pile, an alarm will be sounded. However, when the light is not sufficient at night, the car can only manually judge the distance through the coordination of the reversing lights and the reversing effect, which is very inconvenient. At the same time, if it rains, the light sensor will be obstructed, thereby affecting the sounding of the alarm, causing the car body to collide with the charging pile. In addition, on rainy days, the exposed charging connector will be eroded by rainwater, thereby reducing the service life.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] refer to Figures 1 to 12 A charging pile with a distance reminder structure comprises a charging pile 1 body, which is characterized by: further comprising a flip plate 3, a first connecting rod 101, a first rectangular block 17, a shell 15, a vertical mounting plate 2, a horizontal mounting plate 18, an L-shaped mounting plate 25, a second rectangular block 6, a first fixing plate 8, a second fixing plate 7, a supporting mechanism, a first sliding mechanism, a second sliding mechanism, a distance reminder mechanism, and an alarm mechanism; A flip plate 3 is movably mounted on the front side of the charging pile 1. The flip plate 3 is driven to rotate by a supporting mechanism. The flip plate 3 is used to support the vehicle. Fig.11 , since the rotation center of the flip plate 3 is at a certain height from the ground, an inclined guide platform is placed on the front side of the flip plate 3 to facilitate the vehicle to smoothly enter the top of the flip plate 3 through the inclined guide platform. When the vehicle drives onto the flip plate 3, the flip plate 3 begins to rotate slowly due to the gravity of the vehicle. Since it has just touched the flip plate 3, only a part of the gravity of the vehicle itself is applied to the flip plate 3, and its gravity is not enough to make the flip plate 3 completely flip. The flip plate 3 will slowly flip under the reset force of the reset component described later. As the vehicle gradually and completely enters the flip plate 3, the flip plate 3 rotates slowly, and drives the subsequent distance reminder mechanism and alarm mechanism to start working during the rotation process; The left and right sides of the housing of the charging pile 1 are respectively fixedly connected with a first rectangular block 17 through a first connecting rod 101; The outer side walls of the two first rectangular blocks 17 are respectively fixed with vertical mounting plates 2, and the supporting mechanisms are respectively arranged on the two vertical mounting plates 2. The two first rectangular blocks 17 are used to install the supporting mechanisms; A cavity 102 is provided on the rear wall of the charging pile 1, and a shell 15 is slidably installed in the cavity. The charging connector to be used is detachably arranged in the shell 15. The shell 15 is driven to slide by a first sliding mechanism. The charging connector is connected to the inside of the charging pile 1 through a wire and is hung on the inner wall of the cavity 102 through a hook. When it is gradually opened under the drive of the first sliding mechanism, the charging connector located inside will also be exposed. At this time, the charging connector can be taken off the hook in the cavity for charging; The flip plate 3 drives the first sliding mechanism to work by flipping; The lower parts of the outer walls of the two vertical mounting plates 2 are respectively fixedly mounted with horizontal mounting plates 18, and the upper ends of the outer sides of the two horizontal mounting plates 18 are respectively fixedly mounted with vertical plates of L-shaped mounting plates 25, and first gaps are respectively left between the horizontal plates of the two L-shaped mounting plates 25 and the outer walls of the two vertical mounting plates 2, and the two L-shaped mounting plates 25 are used to mount the second sliding mechanism described later; The second rectangular blocks 6 are fixedly mounted on the upper ends of the horizontal plates of the two L-shaped mounting plates 25; The upper ends of the two second rectangular blocks 6 are respectively slidably mounted with second fixed plates 7, and the two second fixed plates 7 are driven to slide by the second sliding mechanism. The flip plate 3 drives the two second sliding mechanisms to work by flipping. When the flip plate 3 starts to rotate due to the gravity of the vehicle, the two second sliding mechanisms start to work, and the two second fixed plates 7 start to slide under the drive of the two second sliding mechanisms, and the sliding can drive the alarm mechanism described later to start working; The two second sliding mechanisms are respectively arranged in the two first gaps; The upper ends of the two second fixing plates 7 are respectively provided with alarm mechanisms, and the two second fixing plates 7 respectively drive the two alarm mechanisms to work by sliding; The first fixing plates 8 are fixedly installed on the rear side walls of the two second fixing plates 7, and the distance reminder mechanisms are installed on the side walls of the two first fixing plates 8. The two second fixing plates 7 both drive the alarm mechanism to work by sliding. With the sliding of the two second fixing plates 7 and the slow reversing of the vehicle, the driver can better observe the working status of the distance reminder mechanism, thereby realizing the role of real-time reminder, which is convenient for controlling the distance between the rear of the vehicle and the charging pile 1.

[0022] The supporting mechanism comprises a first rectangular slider 5, a first connecting rod 4, and a reset assembly 26; The outer side walls of the two vertical mounting plates 2 are respectively provided with first rectangular sliding grooves 201, and first rectangular sliding blocks 5 are respectively slidably installed in the two first rectangular sliding grooves 201; The first connecting shafts are fixedly mounted on the outer walls of the two first rectangular sliding blocks 5 respectively; The first ends of the first connecting rods 4 are rotatably mounted on the outer walls of the two first connecting shafts respectively; The two side walls of the first end of the flip plate 3 are rotatably arranged between the two vertical mounting plates 2 through the first rotating shaft; Second connecting shafts are respectively installed outside the two side walls of the second end of the flip plate 3; The second ends of the two first connecting rods 4 are rotatably sleeved on the outer side walls of the two second connecting shafts respectively; The two first rectangular sliding blocks 5 are fixedly connected to the side walls of the two first rectangular sliding grooves 201 through the reset components 26 respectively; The two first rotating shafts respectively drive the two second sliding mechanisms to work by rotating. When the vehicle passes the guide platform and falls between the two second rectangular blocks 6, when the rear wheels press against the flip plate 3, the flip plate 3 starts to rotate downward, and in the process of rotation, the first connecting rods 4 on both sides are driven to start deflecting downward. In the process of downward deflection, the two first connecting rods 4 refer to Figure 1, driving the first rectangular sliders 5 on both sides to start sliding backwards, the cooperation of the first rectangular sliders 5 and the first rectangular slide grooves 201 ensures the sliding tracks of the two first rectangular sliders 5 and ensures that they will not fall off during the sliding process. The two first rectangular sliders 5 begin to compress the reset assembly 26 while sliding backwards along the two first rectangular slide grooves 201. When the flip plate 3 gradually turns horizontal under the gravity exerted by the vehicle slowly driving in, the two first rectangular sliders 5 slide backwards to the limit position. At this time, even if the vehicle drives into the limit position before the charging pile 1, after the vehicle leaves, the flip plate 3 is slowly reduced by the gravity of the vehicle, and slowly rotates upward under the reset of the reset assembly 26. When the vehicle completely leaves the flip plate 3, the flip plate 3 is reset.

[0023] The first sliding mechanism comprises a first connecting frame 301, a second connecting frame 1901, a second connecting rod 20, a first sliding rod 19, and a second connecting rod 16; The two first rectangular blocks 17 are respectively provided with rectangular through holes; A first slide bar 19 is slidably installed in each of the two rectangular through holes; The first ends of the two first sliding rods 19 are respectively installed with second connecting frames 1901, and the two second connecting frames 1901 are respectively movably arranged at the front sides of the two first rectangular blocks 17; The middle of the lower ends of the two side walls of the flip plate 3 are respectively installed with first connecting frames 301, and the first ends of the second connecting rods 20 are rotatably installed in the two first connecting frames 301; The second ends of the two second connecting rods 20 are rotatably disposed in the two second connecting frames 1901 respectively; The second ends of the two first sliding rods 19 slide through the two rectangular through holes and are respectively provided with the same second connecting rod 16; The second connecting rod 16 is movably disposed at the rear side of the two first rectangular blocks 17; The rear side walls of the housing 15 are fixed to the middle of the front wall of the second connecting rod 16 by fixing members, Figure 2When the flip plate 3 begins to flip downward due to gravity, the second connecting rods 20 on both sides also begin to deflect downward under the drive of the flip plate 3, and begin to drive the first sliding rods 19 on both sides to slide to the rear side during the deflection process. Since the sliding tracks of the two first sliding rods 19 are limited in the rectangular through holes, and the two rectangular through holes are horizontal, the two first sliding rods 19 will have a driving force for horizontal movement driven by the two second connecting rods 20. The two first sliding rods 19 begin to slide backward under the drive of the driving force and drive the second connecting rod 16 fixedly connected thereto to start sliding backward. During the backward sliding process, the second connecting rod 16 drives the shell 15 fixedly installed thereto to start sliding out backward. The shell 15 is loaded with the second connecting rod 16. The charging connector begins to slide outward and is exposed. At this time, the vehicle just drives into a position suitable for charging on the flip plate 3. The user only needs to remove the connector and charge the vehicle. After the vehicle drives away, the flip plate 3 begins to reset under the reset of the reset component 26, and the two first slide bars 19 also begin to drive the shell 15 to gradually retract into the charging pile to avoid being exposed to the outside for a long time in the standby state, causing erosion in rainy days. It should be noted that charging will only start when the charging connector contacts the vehicle charging port for charging. This is the prior art and will not be described in detail here. It should be noted that the reset component can be a spring rod with a very large stiffness coefficient or a hydraulic device. Due to the fact that the spring rod with a very large stiffness coefficient has a large material strength and processing difficulty, a hydraulic device is preferably selected. Fig.12 By placing a fixed heavy object on the input end of the hydraulic system, an output force equivalent to the gravity of the heavy object can be formed on the output end of the hydraulic system. However, since the vehicle body is too heavy, the cross-section of the input end of the hydraulic system is enlarged. According to Pascal's theorem, the output end of the hydraulic system can form a gravity amplification effect, which is equivalent to using a spring rod with a larger stiffness coefficient. At this time, the output end of the hydraulic system can be connected to the first slider 5. The effect achieved is to balance a vehicle with a larger mass by a heavy object with a smaller mass. This is the prior art and will not be elaborated here.

[0024] A waterproof rubber ring is installed on the top of the shell 15 and cooperates with the cavity 102. Its function is that when the shell 15 is retracted into the charging pile 1, external rainwater will not enter the inside of the shell 15; The bottom wall of the shell 15 is provided with a leakage hole for leaking water. Its function is that when the vehicle is charging, since the shell 15 is in an open state, rainwater entering the shell 15 will also flow out through the leakage hole to avoid rainwater accumulation inside the shell 15.

[0025] The second sliding mechanism comprises a first spur gear 13, a first rack plate 12, a first connecting rod 21, a second connecting rod 2101, and a third connecting rod 22; The two first rotating shafts respectively rotate and penetrate the side walls of the two vertical mounting plates 2 to fix the first spur gears 13, and the two first spur gears 13 are respectively arranged in the two first gaps; The lower ends of the two first spur gears 13 are respectively meshed with the first rack plates 12, and the two first rack plates 12 are respectively slidably mounted on the upper ends of the two horizontal mounting plates 18; First connecting rods 21 are fixedly mounted on the front outer side walls of the two first rack plates 12, and second connecting rods 2101 are mounted above the two first connecting rods 21. A second gap is left between the two first connecting rods 21 and the two second connecting rods 2101 respectively; The upper ends of the two first connecting rods 21 are rotatably mounted with the first ends of the second rotating shafts through thrust bearings, and the second ends of the two second rotating shafts are rotatably connected with the two second connecting rods 2101. The first ends of the third connecting rods 22 are fixedly mounted on the outer side walls of the two second connecting rods 2101 respectively; The inner side walls of the two second rectangular sliding blocks 6 are respectively provided with second rectangular sliding grooves 601, and the second ends of the two third connecting rods 22 are respectively slidably engaged in the two second rectangular sliding grooves 601; The lower ends of the two second fixing plates 7 are fixedly connected to the upper ends of the two second connecting rods 2101 respectively; The two second rotating shafts are respectively rotatably connected with the two second fixing plates 7, and the two second rotating shafts respectively drive the alarm mechanism to work by rotating. Figure 4 When the vehicle drives onto the flip plate 3, the flip plate 3 begins to rotate around the first rotating shaft under the action of gravity. The first spur gear 13 fixedly installed on the two first rotating shafts also has the ability to rotate at this time, and in the process of rotation, it drives the first rack plate 12 meshing therewith to begin to slide to the left. The two first connecting rods 21 fixedly connected to the two first rack plates 12 also begin to slide to the left at this time. In the process of sliding to the left, the two first connecting rods 21 drive the second connecting rods 2101 fixedly connected thereto to begin to slide to the left. Since the vehicle is driving to the right side pressing the flip plate 3 at this time, the driver can observe the two second connecting rods 2101 gradually moving forward from his own perspective through the windows on both sides. The driver can preliminarily judge the driving distance of the vehicle by the distance moved forward by the two second connecting rods 2101, and can accurately know the specific position with the cooperation of the distance reminder mechanism described later.

[0026] The distance reminder mechanism comprises a third connecting rod 14, a second sliding rod 23, an indicating block 24, and a scale line; The two first fixing plates 8 are respectively provided with rectangular through slots 801; The second slide bars 23 are slidably mounted in the two rectangular through slots 801 respectively; The outer walls of the two second sliding rods 23 are respectively fixedly mounted with second connecting shafts, and the first ends of the third connecting rods 14 are respectively rotatably mounted on the two second connecting shafts; The third connecting shafts are fixedly mounted on the front outer walls of the vertical plates of the two L-shaped mounting plates 25, and the second ends of the two third connecting rods 14 are rotatably sleeved on the outer sides of the two third connecting shafts. Indicator blocks 24 are fixedly mounted on the inner walls of the two second slide bars 23, respectively. The two indicator blocks 24 are slidably mounted on the inner walls of the two second fixed plates 7, respectively. A plurality of scale lines are installed at equal intervals on the rear side walls of the two second fixing plates 7; The indicator block 24 on one side is in detachable contact with several scale lines on the same side, refer to Figure 6 When the vehicle is pressed against the flip plate 3, the vehicle is traveling in the right direction, and the two second fixed plates 7 begin to slide to the left under the drive of the two second connecting rods 2101. The two first fixed plates 8 fixedly installed with the two second fixed plates 7 also begin to slide to the left at this time. In the process of sliding to the left, the two first fixed plates 8 begin to drive the third connecting rods 14 on both sides to deflect upward respectively. In the process of deflecting upward, the two third connecting rods 14 respectively drive the second sliding bars 23 located in the two rectangular through grooves 801 to start sliding upward. In the process of sliding upward, the two second sliding bars 23 respectively drive the indicating blocks 24 fixedly connected and installed therewith to start sliding upward. The two indicating blocks 24 will pass through several scale lines respectively in the process of sliding upward. Since the driver can observe the movement of the first fixed plates 8 through the left and right side glasses during the forward movement of the two first fixed plates 8, the precise distance traveled by the vehicle can be obtained according to the sliding of the indicating blocks on the scale lines.

[0027] The indicator block is a luminous indicator block, and its function is that when the charging pile 1 is used at night, the luminous indicator block can be more easily observed by the driver.

[0028] The alarm mechanism comprises a second spur gear 11, a second rack plate 10, and an indicator blade 9; The second rotating shafts located in the two second gaps are respectively fixedly mounted with second spur gears 11; The second rack plates 10 are fixedly mounted on the inner walls of the transverse plates of the two L-shaped mounting plates 25, respectively, and the two second spur gears 11 are respectively meshed with the two second rack plates 10; The two second rotating shafts rotate and penetrate the two second fixing plates 7 and are provided with indicating blades 9; A control panel for counting and indicating the number of rotations of the fan blade 9 is installed in the charging pile 1, and an alarm is installed on the top wall of the charging pile 1. The control panel is electrically connected to the alarm. Figure 6When the vehicle drives onto the flip plate 3, the vehicle's driving direction is right, and the first connecting rods 21 on both sides and the second connecting rods 2101 on both sides slide toward the left side respectively. The second spur gear 11 located between the first connecting rod 21 and the second connecting rod 2101 also starts to slide toward the left side at this time. Since the second spur gear 11 is always in a meshing state with the second rack plate 10 during the sliding process to the left, the second spur gear 11 also starts to rotate during the sliding process, and drives the indicating fan blade 9 coaxially installed therewith to start rotating during the rotation process. The driver can also judge the reversing distance by watching the number of rotations of the indicating fan blade 9. At the same time, as the indicating fan blade 9 rotates, the control panel in the charging pile 1 will count the number of rotations of the indicating fan blade 9, and start to trigger the alarm after the indicating fan blade 9 rotates a certain number of times. Compared with the traditional light sensor alarm, this method completely eliminates the obstruction of the light sensor on rainy days, thereby affecting the sounding of the alarm.

[0029] Implementation method of the present invention: When the device is ready for use, the housing 13 is retracted into the charging pile 1, and the charging connector inside the housing 13 is completely isolated from the outside, thereby protecting the charging connector. At this time, the flip plate 13 is in an upward flipping state under the reset of the reset component 26; When the vehicle passes the guide platform and enters the upper end of the flip plate 3, the flip plate 3 is slowly pressed down, and in the process of slowly pressing down, the first rectangular slider 5 gradually begins to compress the reset component 26. As the vehicle continues to approach the charging pile 1, the driver can observe through the car windows on both sides that the two first fixed plates 8 slide toward the front of the vehicle, and during the sliding process, the indicator block 24 gradually moves upward along the scale line. At this time, the driver can judge the distance between the rear of the vehicle and the charging pile by the stop distance of the indicator block 24 on the scale line. When driving and charging at night, the indicator block 24 will emit light, which is convenient for the driver to observe the indicator block 24 at night and make judgments; As the two first fixing plates 8 move toward the front of the vehicle, the indicating blades 9 located at the upper ends of the two second fixing plates 7 will also rotate accordingly. The longer the driving distance is, the more circles the indicating blades 9 rotate. When the distance between the vehicle and the charging pile 1 reaches the specified limit distance, the number of circles the indicating blades 9 rotate is the limit number of circles. The control panel will count this limit number of circles and transmit a signal to the alarm, which starts to sound to remind the driver not to perform reverse operations. When the vehicle stops at the upper end of the flip plate 3, the housing 15 located on the rear wall of the charging pile 1 is also fully opened. At this time, the driver can take out the charging connector located on the inner wall of the housing 15 and charge his vehicle; After charging is completed, the charging connector is pulled out and placed in the shell 15, and the driver drives away from the flip plate 3. During the driving away process, the flip plate 3 slowly rotates upward again under the reset of the reset component 26, and the shell 15 is also slowly retracted into the charging pile 1 at this time to achieve the effect of rain protection.

[0030] The support mechanism of the present invention uses the gravity of the car itself as a driving source. The support mechanism is driven by the gravity of the car to realize the operation of the subsequent distance reminder mechanism and the alarm mechanism. The shell of the present invention can extend or retract the charging connector into the charging pile body under the drive of the first sliding mechanism. When the vehicle enters the charging area, the shell will automatically open. When the vehicle leaves the charging area, the shell will be retracted to prevent the charging connector from being exposed to the outside for a long time and being eroded by rain.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
