[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0027] Embodiment 1:

[0028] The embodiment of the present invention provides a battery vehicle charging pile with high protection performance, such as Figure 1-Figure 3 As shown, it includes a support column 1 and a ceiling 2, the support column 1 is equipped with a ceiling 2 for sheltering from rain, the support column 1 is equipped with a mounting plate 3, a charging socket 4 is arranged in the middle of the mounting plate 3, a button 5 is arranged in the middle of the charging socket 4, the button 5 is electrically connected to the power supply of the charging pile, and a clamping assembly for clamping the charging plug is installed in the mounting plate 3, and the clamping assembly cooperates with the button 5.

[0029] Furthermore, the clamping assembly includes a motor 6, a bidirectional screw rod 7 and a clamping block 8. The motor 6 is installed in the mounting plate 3. The motor 6 is electrically connected to the button 5. The output shaft of the motor 6 is connected to the bidirectional screw rod 7. The bidirectional screw rod 7 is threadedly connected to clamping blocks 8 that are symmetrically distributed on the left and right. The clamping block 8 is slidably connected to the mounting plate 3. The clamping block 8 is used to clamp the charger plug. The front-to-back distance between the clamping block 8 and the charging socket 4 is the thickness of the charger plug.

[0030] Furthermore, the side wall of the clamping block 8 in contact with the charging plug is an inclined surface, and is provided with pressure sensors symmetrically distributed up and down, and the pressure sensors are electrically connected to the power supply of the charging pile.

[0031] Specifically, the power supply of the charging socket 4 is dually controlled by the button 5 and the pressure sensor. When the button 5 is pressed and the pressure value sensed by the pressure sensor reaches a preset value, the power supply of the charging pile is connected to the charging socket 4, that is, the charging pile power supply, the charging socket 4, the button 5 and the pressure sensor are connected in series in the circuit. In this way, when the plug is not inserted into the charging socket 4, but the button 5 is accidentally pressed, the charging socket 4 will not be powered on, thereby ensuring a certain degree of safety.

[0032] The specific operation is as follows: when the user needs to use the charging pile, the battery car is driven under the roof 2. The battery car is shielded by the roof 2 to block rain and falling objects from the air. The user inserts the plug of the battery car charger into the charging socket 4, and the button 5 is pressed. The button 5 controls the motor 6 to start, so that the output shaft of the motor 6 rotates to drive the bidirectional screw rod 7 to rotate, thereby driving the clamping blocks 8 on the left and right sides to move toward the middle, so that the clamping blocks 8 clamp and fix the charger plug to prevent the charging head from being unplugged by others during charging. At the same time, the inclined surface on the inner side of the clamping block 8 can squeeze and push the charger plug to move toward the charging socket 4 to prevent the user's plug from being fully inserted. When the pressure sensor of the clamping block 8 detects that the pressure reaches the preset value, the charging socket 4 is energized, and the battery car starts to charge.

[0033] Embodiment 2:

[0034] On the basis of Example 1, Figure 4-Figure 6 As shown, it also includes a locking assembly for locking the clamping block 8, the locking assembly includes a sliding rod 9 and a locking rod 10, the sliding rod 9 is slidably connected between the mounting plate 3 and the charging socket 4, the locking rod 10 is slidably connected in the mounting plate 3, and a locking groove is opened on the lower side of the clamping block 8, and the locking groove cooperates with the locking rod 10.

[0035] Furthermore, both sides of the sliding rod 9 are inclined surfaces, and a diamond-shaped groove is provided in the locking rod 10 to match the inclined surfaces of the sliding rod 9 .

[0036] Specifically, in order to prevent the clamping block 8 from extending when the button 5 is accidentally touched, or the charger plug is offset and pushes the button 5 but is not fully inserted, when the charger plug is inserted into the charging jack 4, it will contact the sliding rod 9 and squeeze the sliding rod 9 to move to the left, so that the sliding rod 9 squeezes the locking rod 10 to move downward, so that the locking rod 10 no longer jams the clamping block 8. At this time, the button 5 is pressed by the charger plug again, and the clamping block 8 is no longer jammed. The clamping block 8 can move normally to clamp the charger plug. This operation is mainly to prevent the button 5 from being accidentally touched, as well as malicious operations that intend to damage the clamping block 8.

[0037] Embodiment 3:

[0038] On the basis of Example 2, Figure 4 and Figure 7 As shown, an unlocking member 11 is also included. The unlocking member 11 is fixed to one side of the sliding rod 9 close to the charging socket 4. The unlocking member 11 is used to push the charging head out. An elastic member (not shown in the figure) is connected between the unlocking member 11 and the charging socket 4 for resetting the unlocking member 11.

[0039] Furthermore, it also includes a linkage component, which includes a driving member 12, a rotating rod 13, a torsion spring 14, a push rod 15 and a wedge block 16. The driving member 12 is fixed to the lower side of the clamping block 8, the rotating rod 13 is connected to the sliding rod 9, the push rod 15 is rotatably connected to the rotating rod 13, a torsion spring 14 is connected between the rotating rod 13 and the push rod 15, and a wedge block 16 is arranged on the top of the push rod 15.

[0040] Furthermore, the driving member 12 is composed of an outer rod and an inner rod with an internal spring. The side of the inner rod close to the wedge block 16 is an inclined surface. When the driving member 12 moves inward, it will move to contact the wedge block 16 and be squeezed by the wedge block 16. The inner rod slides inwardly of the outer rod until it passes over the wedge block 16, and then the inner rod is reset under the action of the internal spring.

[0041] Specifically, in order to prevent the charger from being damaged due to the charger being fixed and unable to be pulled out in an emergency, when the charging cable is pulled, the charging head will also be pulled to a certain extent, so that the pressure values ​​sensed by the pressure sensors on the upper and lower sides of the clamping block 8 are different. At this time, the motor 6 starts, driving the bidirectional screw rod 7 to rotate, thereby driving the clamping block 8 to loosen the plug, and the clamping block 8 moves outward to drive the driving member 12 to move outward, thereby driving the wedge block 16 and the push rod 15 to move to the left, so that the sliding rod 9 moves to the left, driving the unlocking member 11 to move to the left, and the unlocking member 11 moves to the left to push the charger plug outward. In this way, the charger can be effectively prevented from being damaged. After the unlocking member 11 moves into the hole of the charging jack 4, it no longer moves, the sliding rod 9 no longer moves, and the clamping block 8 continues to move outward. At this time, the push rod 15 flips to the left, causing the torsion spring 14 to deform. When the driving member 12 passes over the push rod 15, the torsion spring 14 resets and drives the push rod 15 to reset.

[0042] In some embodiments, a buffer plate 17 is also included. The buffer plate 17 is arranged at the lower part of the support column 1. A buffer spring 18 is connected between the buffer plate 17 and the support column 1. An arc-shaped buffer block 19 is arranged on the lower side of the buffer plate 17. The buffer plate 17 and the buffer spring 18 weaken the collision of the battery vehicle on the charging pile, and the arc-shaped buffer block 19 weakens the impact force of the battery vehicle.

[0043] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
