TECHNICAL FIELD
[0001] The present application relates to a charging pile, more particularly, it relates to a charging pile with a protection device. BACKGROUND
[0002] Common electric vehicles and electric bicycles need to be charged, so public charging piles have emerged. As one of the terminals of the power grid, the charging pile has a large load voltage and a high manufacturing cost. The most common way of human damage to the charging pile is vehicle impact. The charging pile in the prior art will break after being impacted by a vehicle, and then the control power component will be impacted by the vehicle and hit the ground, causing damage. Even if there is a total power supply fuse, the broken wire will still be in an energized state for a long time before the fuse takes effect, which will endanger the safety of surrounding personnel. Therefore, a charging pile with a protection device is needed to protect the control power component.
[0003] In view of the above reasons, how to protect the control power component is the problem considered by the present application. SUMMARY
[0004] In view of the deficiencies in the prior art, a charging pile with a protection device is provided, which can protect the control power component.
[0005] To achieve the above-mentioned purpose, the following technical solutions are provided:
[0006] A charging pile with a protection device, comprising a fixed shell, the fixed shell being slidably connected with a movable shell, the movable shell being fixedly connected with a buffer for reducing impact, the inside of the movable shell being fixedly connected with a mounting plate, the mounting plate being fixedly connected with a control power component, the control power component being electrically connected with a first plug, the first plug being connected with a first socket fixedly connected with the fixed shell and electrically connected with a total power supply, the mounting plate further being fixedly connected with a partition for separating the first plug and the first socket;
[0007] When the movable shell moves under impact, the partition will move and insert between the first plug and the first socket to separate the first plug and the first socket.
[0008] In summary, the above-mentioned technical solution has the following beneficial effects: the control power component is the core component of the charging pile and needs to be protected first, so a buffer is provided to reduce the impact of hitting the ground. When the movable shell is impacted by a vehicle, it will move relative to the fixed shell and simultaneously move the control power component, which can effectively reduce the impact of the vehicle impact on the control power component.
[0009] In addition to the need to protect the electrical control assembly itself, the broken wire caused by the impact can also cause casualties to the surrounding personnel, therefore, the first plug and the first socket are arranged, the first plug is kept inserted into the first socket under normal circumstances, when the moving shell receives the impact of the vehicle, the partition on the mounting plate moves with the moving shell, but the first socket is fixedly connected with the fixed shell, therefore, the first socket does not move together with the first plug, the partition gradually inserts between the first plug and the first socket with the movement, thereby gradually forcing the first plug and the first socket to be separated, so that the power line in the charging pile can be powered off in advance when the impact occurs, to prevent the power line from being broken and leaking;
[0010] The application adopts the moving shell and the buffer to protect the electrical control assembly, reduces the probability of damage of the electrical control assembly after the impact occurs, thereby reducing the maintenance cost of the charging pile, and further adopts the partition, the first plug and the first socket to realize the power-off in advance when the impact occurs, prevent the power line from being broken and leaking, and also prevent the voltage fluctuation caused by the sudden breakage of the power line from causing the insulation breakdown of some elements in the electrical control assembly, to further protect the electrical control assembly.

[0021] The application will be described in further detail below with reference to the drawings and embodiments. Identical parts are denoted by identical reference numerals in the description. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom" and "top", "inner" and "outer" refer to the directions towards or away from the geometric center of a particular part.
[0022] Referring to Figures 1-4 As shown in the drawings, a charging pile with a protection device comprises a fixed shell 1, the fixed shell 1 is slidingly connected with a movable shell 2, the movable shell 2 is fixedly connected with a buffer 3 for reducing impact, the inside of the movable shell 2 is fixedly connected with a mounting plate 4, the mounting plate 4 is fixedly connected with an electric control assembly 5, the electric control assembly 5 is electrically connected with a first plug 51, the first plug 51 is connected with a first socket 52 fixedly connected with the fixed shell 1 and electrically connected with a general power supply, and the mounting plate 4 is further fixedly connected with a partition 41 for separating the first plug 51 and the first socket 52;
[0023] When the movable shell 2 moves under impact, the partition 41 will move and be inserted between the first plug 51 and the first socket 52 to separate the first plug 51 and the first socket 52;
[0024] The electric control assembly 5 is the core component of the charging pile and needs to be protected first, so the buffer 3 is provided to reduce the impact caused by hitting the ground, when the movable shell 2 is hit by a vehicle, it will move relative to the fixed shell 1 and at the same time drive the electric control assembly 5 to move, which can effectively reduce the impact of the vehicle hitting on the electric control assembly 5;
[0025] In addition to the protection of the electric control assembly 5 itself, the broken electric wire caused by impact can also cause casualties around, so the first plug 51 and the first socket 52 are provided, under normal circumstances, the first plug 51 remains inserted into the first socket 52, when the movable shell 2 is hit by a vehicle, the partition 41 on the mounting plate 4 will move with the movable shell 2, but the first socket 52 is fixedly connected with the fixed shell 1, so it will not move with the first plug 51, the partition 41 gradually inserts between the first plug 51 and the first socket 52 as it moves, thereby gradually forcing the separation of the first plug 51 and the first socket 52, so that the electric wire in the charging pile can be disconnected first when the impact occurs, preventing electric shock caused by broken electric wire;
[0026] The application adopts the mobile shell 2 and the buffer 3 to protect the control and power component 5, reduces the probability of damage of the control and power component 5 after the impact occurs, thereby reducing the maintenance cost of the charging pile, and further adopts the separator 41, the first plug 51 and the first socket 52 to realize the power-off in advance when the impact occurs, prevent the wire from being broken and leaking, and also prevent the voltage fluctuation caused by the sudden breakage of the wire from causing the insulation breakdown of some elements in the control and power component 5, thereby further protecting the control and power component 5.
[0027] Further, the first plug 51 is a column with a pentagonal cross section, the separator 41 is a column with a right trapezoidal cross section, the inclined tip of the separator 41 is arranged at the connection position of the first plug 51 and the first socket 52, and the inclination angle of the inclined surface of the separator 41 in the horizontal direction is the same as the inclination angle of the inclined surface of the first plug 51 in the horizontal direction, so that the first plug 51 and the first socket 52 can be separated more smoothly when the separator 41 moves.
[0028] Further, the fixed shell 1 is further fixedly connected with a support column 6, the mobile shell 2 is provided with a first through slot 21 for the support column 6 to pass through, the support column 6 is rotatably connected with a base 7, and the base 7 is provided with an accommodating groove 71 for accommodating the rotated support column 6.
[0029] The support column 6 can lift the charging pile to a suitable position, and when the charging pile is impacted, the support column 6 can rotate to force the charging pile to move away from the impacted area, thereby avoiding the breakage of the charging pile and the support column 6, and further reducing the impact by reducing the contact time of the charging pile and the vehicle.
[0030] Further, the first socket 52 is electrically connected with a second plug 53 arranged in the base 7, the second plug 53 is fixedly connected with a connecting piece 54 fixedly connected with the support column 6, and the second plug 53 is further connected with a second socket 55 fixedly connected with the base 7 and electrically connected with the total power supply.
[0031] The second plug 53 comprises an arc-shaped plug piece 56, and the center of the arc is consistent with the center of the rotation track of the support column 6, and the second socket 55 is provided with an accommodating cavity 57 for accommodating the plug piece 56, and the accommodating cavity 57 is arc-shaped and the center of the arc is consistent with the center of the rotation track of the support column 6.
[0032] The second socket 55 is fixedly connected with a track 58 for guiding the movement of the second plug 53, the extension direction of the track 58 is arc-shaped, and the center of the arc is consistent with the center of the rotation track of the support column 6.
[0033] When the support column 6 rotates when the charging pile is impacted, the second plug 53 fixedly connected with the support column 6 will gradually move away from the second socket 55, so that the wire in the support column 6 can be powered off when the impact occurs, thereby preventing the wire from being broken and leaking.
[0034] Since the rotating track of the support column 6 is a circular arc, the center of the circular arc-shaped insertion piece 56 and the accommodation cavity 57 is consistent with the center of the rotating track of the support column 6, so as not to hinder the rotation of the support column 6, and the track 58 guides the movement of the second plug 53, so that the second plug 53 can be conveniently reinserted into the second socket 55 when the support column 6 is reset.
[0035] Further, the fixed shell 1 is further fixedly connected with a positioning piece 11, and the positioning piece 11 is fixedly connected with a plurality of springs 12 fixedly connected with the mounting plate 4;
[0036] The support column 6 can only rotate in the direction towards the buffer 3, and the moving shell 2 is fixedly connected with a steel wire 22 at the end away from the buffer 3, and the fixed shell 1 is fixedly connected with a first pulley 13 for changing the extension direction of the steel wire 22 at the end away from the support column 6, and the mounting plate 4 is further fixedly connected with a protection tube 42 for protecting the steel wire 22, and the steel wire 22 passes through the protection tube 42 and the support column 6 and is connected to the base 7;
[0037] The base 7 is further provided with a second pulley 72 for changing the extension direction of the steel wire 22 and a motor 73 connected with the steel wire 22;
[0038] Since the support column 6 can rotate, the spring 12 and the steel wire 22 are designed to control the rotation of the support column 6, when the steel wire 22 is tight, the steel wire 22 generates a force to move the moving shell 2, and this force is offset by the spring 12, so as to be in a balanced state, and the rotation of the support column 6 needs to break the balance, and the force required to break the balance is much greater than the elastic force of the spring 12, so it is difficult to rotate the support column 6 under normal circumstances;
[0039] When the charging pile is hit, the moving shell 2 moves, at this time, the distance between the end of the moving shell 2 away from the buffer 3 and the fixed shell 1 is reduced, so the steel wire 22 is no longer tight, and the support column 6 can rotate, so that the support column 6 can start to rotate when hit by a vehicle, reducing the actual impact force and further protecting the charging pile;
[0040] When the charging pile falls down, the motor 73 can be started to re-tighten the steel wire 22, and according to the shortest distance between two points, pulling the steel wire 22 can automatically support the charging pile, at this time, the end of the moving shell 2 away from the buffer 3 is close to the fixed shell 1, so after the charging pile is reset, the motor 73 needs to be manually controlled to release part of the steel wire 22 to reset the moving shell 2.
[0041] Further, the mounting plate 4 is further provided with a cavity 43 for placing a charging cable and a second through groove 44 communicating between the two sides of the mounting plate 4, and the control component 5 is further electrically connected with a display screen 59 fixedly connected with the mounting plate 4;
[0042] Since the first plug 51 and the first socket 52 are in the charging pile, it is necessary to confirm that the situation is appropriate before re-energizing, so the manual reconnection mode is adopted, and the first plug 51 and the first socket 52 can be reconnected from the outside of the charging pile through the second through slot 44.
[0043] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-described embodiments. Any technical solution that belongs to the concept of the present application shall be within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, some improvements and refinements without departing from the principles of the present application shall also be considered as the protection scope of the present application.
