Description

Technical Field

[0001] The present invention relates to the field of new energy equipment, in particular to a high-power charging pile. Background Art

[0002] With the continuous development of new energy vehicles, the charging power of the public charging piles that match them is also constantly upgraded. At present, the 800V high-voltage charging platform has gradually become popular. It is well known that as the power of the charging pile increases, the corresponding cables will become thicker and heavier. This is bound to cause certain difficulties in the use process, especially for some weak women when using high-power charging guns.

[0003] Therefore, some solutions are provided in the prior art, such as the application number: 202210991172.4, the patent name: Mechanical auxiliary device and charging pile for charging pile, in which a mechanical auxiliary device that can rotate and reset is installed on the charger to assist in supporting the cable. There is also an application number: 202311108917.9, the patent name: A mechanical auxiliary device for charging piles, which also has a structure similar to a mechanical arm installed on the charger, and drives the mechanical arm to swing up and down and move left and right to achieve auxiliary support drive of the cable. The above-mentioned prior arts are all aimed at solving the problem of heavy cables and inconvenient operation for personnel.

[0004] However, the above device has the following disadvantages: First: Currently, the more common auxiliary supporting device is installed on the charger, but in practice the length of the cable is significantly longer than the supporting device, and the supporting position is equivalent to the root of the cable, deviating from the actual force position, and does not play a more effective auxiliary and labor-saving effect.

[0005] Second: Although the auxiliary equipment in the prior art can be rotated or moved left and right, in actual use, the cable movement angle should be wider. The existing auxiliary equipment installed on the charger has the defect of limiting the movement range of the cable, and the mobility and adaptability are poor. It is too dependent on the vehicle parking position.

[0006] Third: The existing auxiliary equipment is also cumbersome to install and use, has poor adaptability, and is not convenient for later installation. Overall, it is not conducive to widespread application and promotion.

[0007] To this end, the present invention specifically provides a new charging pile with auxiliary supporting equipment to improve the problems of cumbersome operation and inconvenient use of existing high-power charging piles. Summary of the invention

[0008] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a high-power charging pile, which effectively solves the problems raised in the background technology.

[0009] The technical solution to the problem is as follows: a high-power charging pile includes a charger, a cable and a charging gun head, characterized in that a supporting device is installed on the cable, and the supporting device includes two left and right first bases and two front and rear second bases, the lower end of each first base is provided with two rotating shafts that can rotate synchronously in opposite directions, the two adjacent rotating shafts on the two first bases are fixedly connected via a first connecting rod, and the other rotating shaft on the first base is fixedly connected to the second base adjacent to it via a second connecting rod, the length of the first connecting rod is twice that of the second connecting rod, the first base, the second base, the second connecting rod and the first connecting rod together form a Z-shaped structure, universal wheels are provided under the first base and the second base, the upper ends of the two first bases and the second base located on the rear side are provided with a clamp, and an inclined bracket is fixed on the second base located on the front side, a limit rod is provided at the lower end of the bracket, a positioning cylinder is provided at the upper end of the bracket, the cable is locked along the Z-shaped structure via the clamp, and the end charging gun head can be inserted into the positioning cylinder after bypassing the limit rod.

[0010] In order to realize the driving of the two rotating shafts on the first base, the first base includes a rectangular cavity, in which two gears are rotatably installed, the rotating shaft is coaxially fixed with the corresponding gears and the lower end extends out of the cavity, a double-sided rack meshing with both gears is provided between the two gears, and an electric cylinder for driving the rack to move is provided on the outside of the cavity.

[0011] In order to achieve the stability of the supporting device, an inverted T-shaped frame is provided under the first base, the electric cylinder is fixed on the inverted T-shaped frame, two universal wheels are provided at the lower end of the inverted T-shaped frame, and the inverted T-shaped frame does not interfere with the rotating shaft. The second base is a rectangular plate perpendicular to the second connecting rod, and two universal wheels are provided at the lower end of each rectangular plate.

[0012] In order to better fix the cable, a clamp is also provided in the middle of the first connecting rod. All the clamps are installed on the Z-shaped structure through the axis rotation. The clamp is split and a cushion layer is provided on the inner side of the clamp.

[0013] In order to realize the driving of the bracket, a handle is provided on one side of the bracket, and a switch for controlling the synchronous extension and retraction of the two electric cylinders is provided on the handle.

[0015] In order to improve the stability of the bracket, the bracket is U-shaped, the upper end of the bracket is inclined toward the direction of the second connecting rod fixed on the second base on the front side, and the positioning cylinder installed on the bracket keeps the axis horizontal.

[0016] The present invention has the following advantages: 1. The present invention uses a Z-shaped structure to lock the middle position of the cable in a Z-shape as a whole. This can not only achieve overall support for the cable to avoid damage caused by friction between the cable and the ground during dragging, but also achieve convenient movement through the universal wheels on the Z-shaped structure.

[0017] 2. The cable locked in a Z shape can be stretched into a straight line or folded into an S shape under the drive of the electric cylinder, which can meet the needs of cables of different lengths. The power source for folding the cable comes from the electric cylinder, and the worker only needs to apply a small amount of force. The guide can be completed by providing appropriate traction on the handle, which is simple and labor-saving to operate.

[0018] 3. The present invention places a secondary screen on the bracket, which can be operated beside the car, avoiding the need for the user to go to the motor to scan the code for operation, making the whole process more convenient.

[0019] 4. The present invention has a simple structure, which is convenient for subsequent installation and upgrading. At the same time, the production cost and use cost of the device are relatively low, and it is suitable for wide promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Example

[0028] Depend on Figures 1 to 5 It can be seen that a high-power charging pile of the present invention includes a charger 1, a cable 2 and a charging gun head 3, and a supporting device is installed on the cable 2, and the supporting device is a Z-shaped structure. The two ends of the Z-shaped structure are two second bases 5, and the bending position of the Z-shaped structure is the first base 4. The first base 4 includes a rectangular cavity, and two gears 13 are rotatably installed in the cavity. The lower end of the gear 13 is coaxially fixed with a rotating shaft extending from the lower end of the cavity. A double-sided rack 14 meshing with both gears 13 is provided between the two gears 13, and an electric cylinder 15 for driving the rack to move is provided on the outside of the cavity. The first base 4 is fixed to the first base 4 through a first connecting rod 6, and the two ends of the first connecting rod 6 are respectively fixed on the corresponding rotating shafts. The first base 4 and the second base 5 are fixed through a second connecting rod 7, and the second connecting rod 7 is fixed on another rotating shaft of the first base 4. The length of the first connecting rod 6 is twice the length of the second connecting rod 7.

[0029] Universal wheels 8 are provided below the first base 4 and the second base 5. An inverted T-shaped frame 16 is provided below the first base 4. The electric cylinder 15 is fixed on the inverted T-shaped frame 16. Two universal wheels 8 are provided at the lower end of the inverted T-shaped frame 16. The inverted T-shaped frame 16 does not interfere with the rotating shaft. The second base 5 is a rectangular plate perpendicular to the second connecting rod 7. Two universal wheels 8 are provided at the lower end of each rectangular plate. Hoops 9 are installed at the upper ends of the two first bases 4 and the second base 5 located at the rear side. A hoop 9 is also provided in the middle of the first connecting rod 6. All hoop 9 are installed on the Z-shaped structure through the axis rotation. The hoop 9 is a split type, and a cushion layer is provided on the inner side of the hoop 9.

[0030] An inclined bracket 10 is fixed on the second base 5 located on the front side. The bracket 10 is U-shaped. The upper end of the bracket 10 is inclined in the direction of the second connecting rod 7 fixed on the second base 5 located on the front side. The positioning cylinder 12 installed on the bracket 10 keeps the axis horizontal. A handle 17 is provided on one side of the bracket 10, and a switch for controlling the synchronous extension and retraction of the two electric cylinders 15 is provided on the handle 17. A limit rod 11 is provided at the lower end of the bracket 10, and a positioning cylinder 12 is provided at the upper end of the bracket 10. The cable 2 is locked along the Z-shaped structure through the clamp 9. After bypassing the limit rod 11, the end charging gun head 3 can be inserted into the positioning cylinder 12. A secondary screen 18 is installed on the frame.

[0031] The design principle and working process of the present invention: First, the present invention can be installed later, and connecting rods of different sizes can be selected according to different needs to limit the Z-shaped structure. During the installation process, the clamp 9 and the limiting rod 11 on the bracket 10 are opened, and the middle section of the cable 2 is placed on the Z-shaped structure and fixed by the clamp 9. The charging gun head 3 passes through the bracket 10 and is limited by the limiting rod 11 close to the cable 2 of the charging gun head 3. The charging gun head 3 can be inserted into the positioning cylinder 12. Under the action of the electric cylinder 15, the Z-shaped structure can be stretched into a straight line, and the Z-shaped structure can also be gathered to the middle. The state shown in the attached figure of the present invention is the intermediate state.

[0032] Two switches are provided on the handle 17, one for controlling the synchronous extension of the electric cylinder 15, and the other for controlling the synchronous retraction of the electric cylinder 15. When not in use, the electric cylinder 15 can be retracted by pressing the switch for controlling the synchronous retraction of the electric cylinder 15. The retraction of the electric cylinder 15 enables the double-sided rack 14 to mesh with the gear 13 to move toward each other. At this time, the shaft drives the first connecting rod 6 and the second connecting rod 7 to gradually gather and retract. In this process, the cable 2 on the Z-shaped structure is gradually folded into an S shape. In this process, the charging gun head 3 moves closer to the charger 1 under the auxiliary guidance of manual operation.

[0033] Similarly, when using the charging pile for charging, the user holds the handle and presses the switch to extend the electric cylinder 15. In this process, the manual guide drive, in conjunction with the double-sided rack 14, drives the gear 13 to engage in transmission to achieve continuous extension of the Z-shaped structure, and finally the cable 2 can be elongated. In this process, since there are two universal wheels 8 on the first base 4 and the second base 5, the device will not fall over even if the Z-shaped structure is unfolded into a straight line.

[0034] During the use of the entire device, the user only needs to hold the handle 17, press the switch, and provide a small guiding driving force to move the bracket 10 with the charging gun head 3 to the charging port of the vehicle. At this time, the charging gun head 3 is pulled out and charged. At the same time, the bracket 10 also provides a secondary screen 18 service, which can be used for direct code scanning operations, and the specific charging status can be viewed in real time.

[0035] After completion, the charging gun head 3 can be reset by pulling out the charging gun head 3. At this time, the Z-shaped structure can be retracted by holding the handle and providing the guide drive while pressing the switch. In this process, the user uses the guide drive mainly to avoid obstacles and prevent the device from contacting the vehicle. The guide force provided is much smaller than the traditional force consumed by taking the gun head out of the charger 1 and resetting it.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
