Description

Technical Field

[0001] The utility model relates to the field of charging piles, and in particular to a protective device for charging piles. Background Art

[0002] The charging port of an electric vehicle is generally located at the rear side of the vehicle. When charging, the vehicle will be backed up next to the charging pile and the charging gun will be used to connect to the vehicle's charging port for charging. A Chinese utility model patent with announcement number CN218021246U discloses an anti-collision protection device for a charging pile, including a base, a fixed box, and a charging box. The device provides protection for the fixed box by closing two anti-collision plates in front of the fixed box, and the anti-collision plate compresses the spring, which absorbs and mitigates the impact and improves the anti-collision protection effect. If the vehicle does not stop in time during the reversing process, it will contact the anti-collision plate and cause a collision with it. When the vehicle's sheet metal is hit, it may be slightly deformed or scratched to a certain extent, which will cause damage to the surface of the vehicle. To this end, we have designed a protective device for charging piles. Utility Model Content

[0003] In order to solve the technical problem that the anti-collision plate contacts the car and causes a collision, so that the sheet metal parts of the car may be slightly deformed or scratched to a certain extent when hit, the utility model provides a protective device for a charging pile.

[0004] The utility model is implemented by the following technical scheme: a protective device for a charging pile, comprising a charging pile, a base is arranged on the right side of the charging pile, a swing frame that swings left and right is installed at the middle of the front and rear surfaces of the base through a swing axis, a contact roller is installed between the front and rear two swing frames through an axle rod, and a plurality of linearly distributed tripods are arranged on the upper surface of the base, a support wheel is installed on the inward side of each tripod through an axle rod, and the support wheel is on the left side of the contact roller.

[0005] As a further improvement of the above scheme, embedding grooves are provided on the front and rear sides of the base, and a torsion spring is fixed in the embedding groove. The outward side of the torsion spring is fixed to the swing shaft, and the swing shaft is rotatably connected to the side surface of the base through a bearing. The torsion spring enables the swing shaft and the swing frame to return to their initial state after being deflected to the left without being subjected to external force.

[0006] As a further improvement of the above scheme, the outer ring surfaces of the contact roller and the support wheel are designed to be smooth, the axis of the support wheel is on the deflection trajectory of the contact roller, the deflection angle of the contact roller is 0-30 degrees, the contact roller will swing along a fixed track with the swing axis as the axis, and when the contact roller swings 30 degrees, the outer ring surface of the contact roller will contact the outer ring surfaces of multiple support wheels and be in a tangent state, and the two can rotate between them.

[0007] As a further improvement of the above scheme, the base includes a contact slope and a contact plane, and the contact slope and the contact plane have an included angle of 3-7 degrees, and the contact plane and the contact slope are connected at a rounded corner to form a connecting arc surface. The design of the contact slope enables the wheels of the car to move upward along its surface to the contact plane, and there will be a certain fluctuation when moving above the contact slope, which can remind the driver that the distance to the charging pile is too close and the driver should stop in time.

[0008] As a further improvement of the above scheme, three linearly distributed rolling grooves are opened on the contact plane of the base, and rotating rollers are rotatably installed in the three rolling grooves through shafts, and the outer ring surface of the rotating roller is in rolling contact with the inner wall of the rolling groove. The upper part of the outer ring surface of the rotating roller is above the contact plane, and the outer ring surface of the rotating roller is roughly designed to form anti-slip grooves. When the car wheel moves above the rotating roller, the rear side of the wheel will push the contact roller to deflect to the left, which can cause the wheel to slip and cannot continue to move backward.

[0009] As a further improvement of the above solution, the upper surfaces on both sides of the rolling groove are chamfered to form arcuate surfaces, and the arcuate surfaces are tangent to the inner walls on both sides of the rolling groove. The arcuate surfaces are widened so that the rotating roller can be directly placed in the rolling groove, thereby facilitating the installation and removal of the rotating roller.

[0010] The bottom ends of the rolling grooves are recessed downward to form drainage outlets, which run through the front and rear sides of the base and are connected to the outside. The middle of the drainage outlets is higher than the front and rear ends. Rainwater falling into the rolling grooves on rainy days can be directly discharged through the drainage outlets, avoiding the accumulation of rainwater.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model arranges a contact roller deflected to the left on the top of the base. The deflected contact roller can play a certain buffering effect on the car, and can remind the driver to stop reversing. Cooperating with the support wheel arranged on the rear side of the contact roller, the support wheel makes the contact roller deflect to the left with a limited angle and can support it, so that the car can not continue to reverse backwards and can be forced to stop;

[0013] 2. By arranging a plurality of rotating rollers above the base, the rear wheels of the car can be placed on the rotating rollers, and the contact rollers are arranged so that the wheels can idle on the top, so that the wheels cannot move backwards and will not cause too much wear to the wheels.

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0021] Example:

[0022] Please combine Figure 1-Figure 4 A protective device for a charging pile in this embodiment includes a charging pile 6, a base 1 is arranged on the right side of the charging pile 6, and a swing frame 3 that swings left and right is installed in the middle of the front and rear surfaces of the base 1 through a swing shaft 31, and a contact roller 4 is installed between the front and rear swing frames 3 through an axle rod rotation, and a plurality of linearly distributed tripods are arranged on the upper surface of the base 1, and a support wheel 5 is installed on the inward side of each tripod through an axle rod rotation, and the support wheel 5 is on the left side of the contact roller 4.

[0023] Embedding grooves are provided on both the front and rear sides of the base 1, and a torsion spring 7 is fixed in the embedding groove. The outward side of the torsion spring 7 is fixed to the swing shaft 31, and the swing shaft 31 is rotatably connected to the side surface of the base 1 through a bearing. The torsion spring 7 enables the swing shaft 31 and the swing frame 3 to return to their initial state after being deflected to the left without being subjected to external force.

[0024] The outer ring surfaces of the contact roller 4 and the support wheel 5 are designed to be smooth. The axis of the support wheel 5 is on the deflection trajectory of the contact roller 4. The deflection angle of the contact roller 4 is 0-30 degrees. The contact roller 4 will swing along a fixed track with the swing shaft 31 as the axis. When the contact roller 4 swings 30 degrees, the outer ring surface of the contact roller 4 will contact the outer ring surfaces of multiple support wheels 5 and be in a tangent state, and the two can rotate between them.

[0025] The base 1 includes a contact slope 11 and a contact plane 12. The contact slope 11 and the contact plane 12 have an included angle of 3-7 degrees, and the contact plane 12 and the contact slope 11 are connected at a rounded corner to form a connecting arc surface. The design of the contact slope 11 enables the wheels of the car to move upward along its surface to the contact plane 12, and there will be a certain fluctuation when moving above the contact slope 11, which can remind the driver that the distance to the charging pile 6 is too close and the driver should stop in time.

[0026] Three linearly distributed rolling grooves 122 are provided on the contact plane 12 of the base 1, and rotating rollers 2 are rotatably installed in the three rolling grooves 122 through shafts, and the outer ring surface of the rotating roller 2 is in rolling contact with the inner wall of the rolling groove 122. The upper part of the outer ring surface of the rotating roller 2 is above the contact plane 12. The outer ring surface of the rotating roller 2 is roughened to form anti-skid patterns. The design of the anti-skid patterns facilitates the car to move forward and leave the rotating roller 2. When the car wheel moves to the top of the rotating roller 2, the rear side of the wheel will push the contact roller 4 to deflect to the left, which can cause the wheel to slip and cannot continue to move backward.

[0027] The upper surfaces of the left and right sides of the rolling groove 122 are chamfered to form arcuate surfaces 123, and the arcuate surfaces 123 are tangent to the inner walls of the left and right sides of the rolling groove 122. The arcuate surfaces 123 are widened so that the rotating roller 2 can be directly placed in the rolling groove 122, thereby facilitating the installation and removal of the rotating roller 2.

[0028] The bottom ends of the rolling grooves 122 are recessed downward to form drain outlets 121, which run through the front and rear sides of the base 1 and are connected to the outside. The middle of the drain outlet 121 is higher than the front and rear ends. Rainwater falling into the rolling grooves 122 on rainy days can be directly discharged through the drain outlet 121, avoiding the accumulation of rainwater.

[0029] The implementation principle of a protective device for a charging pile 6 in the embodiment of the present application is as follows: in actual use, the wheels of the car will be lifted along the contact slope 11 during the reversing process, which can remind the driver that the distance to the charging pile 6 is close and the driver should stop in time. When the car is not stopped and is still reversing, the wheel will move above the rotating roller 2 and will exert a force to the left on the contact roller 4, thereby causing the contact roller 4 to deflect to the left. The contact roller 4 deflected to the left can have a certain buffering effect on the car, reminding the driver again that the reversing should be stopped. When the contact roller 4 deviates to the left to the maximum extent, it will contact the supporting wheel 5. At this time, the contact roller 4 cannot continue to deflect to the left, which will force the wheel to be unable to retreat, and the wheel will be completely on the rotating roller 2, and the rear side of the wheel will contact the contact roller 4, so that the rotating vehicle will idle and cannot continue to reverse, so that the car is forced to stop reversing, so that the car will not collide with the charging pile 6, avoiding damage to the car and the charging pile 6;

[0030] By arranging a contact roller 4 deflected to the left on the top of the base 1, the deflected contact roller 4 can play a certain buffering effect on the car, and can remind the driver to stop reversing. Cooperating with the support wheel 5 arranged on the rear side of the contact roller 4, the support wheel 5 makes the contact roller 4 deflect to the left with a limited angle and can support it, so that the car can no longer reverse backwards and can be forced to stop;

[0031] By arranging a plurality of rotating rollers 2 for rotation above the base 1, the rear wheels of the car can be placed on the rotating rollers 2, and the contact rollers 4 are arranged in cooperation so that the wheels can idle on the top, so that the wheels cannot move backwards and will not cause too much wear to the wheels.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
