Description

Technical Field

[0001] The present invention relates to the technical field of automobile charging equipment, and in particular to an automobile charging pile and a surface shell assembly thereof. Background Art

[0002] With the popularity of electric vehicles, public charging piles have been laid out in cities to facilitate electric vehicle drivers to charge their vehicles in time when they are out of power.

[0003] The existing charging pile has a pile body, a charging head and a cable connecting the pile body and the charging head. The length of the cable is generally about 7 meters. After charging, there is generally a hanger on the pile body. The user rolls up the cable and places it on the hanger for the next user to use. Since the hanger only provides support for the coiled cable but cannot limit and maintain the coiling form, the cable is often not wound in a standardized manner and dragged on the ground. This phenomenon will cause the part of the cable dragging on the ground to be crushed by the car and easily damaged. In severe cases, it will cause the cable to be entangled in the car chassis and torn after being dragged as the car moves, which can easily cause the risk of electric shock. Summary of the Invention

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Reference Attachment Figure 1 -Attached Figure 5 A car charging pile cover assembly includes: a winding column 1, which is a cylindrical structure and is fixed to the side of the charging pile; a plurality of fixing blocks 2, which are fixed on the outer edge of the winding column 1 and are located at the top of the winding column 1; a card block, which is arranged on one side of the fixing block 2 and can elastically slide out into the area between two adjacent fixing blocks 2; wherein the card block elastically slides out to squeeze and touch the cable located between the two adjacent card blocks, and the card block, the fixing block 2 and the outer edge of the winding column 1 together form a three-point squeezing of the cable.

[0028] Through the above technical solution, the cable is wound on the winding column 1 in the form of a coil, and a clamping block that can slide elastically is used to squeeze and touch the cable, pushing the cable until the cable is squeezed against the clamping block, the fixed block 2 and the outer edge of the winding column 1 at the same time, thereby forming a restriction on the cable itself, overcoming the problem that the cable is difficult to maintain after being wound and placed on the hanging rack, causing the cable to drag on the ground due to lack of restriction.

[0029] A fixing groove 3 is provided in the fixing block 2, and the clamping block is slidably connected to the fixing groove 3. An elastic groove 4 is provided in the fixing block 2, and the elastic groove 4 is communicated with the fixing groove 3. A fixed shaft 5 is fixedly connected in the elastic groove 4, and a slider 6 is slidably connected in the elastic groove 4. The fixed shaft 5 passes through the slider 6, and the slider 6 is fixedly connected to the clamping block. A compression spring 7 is sleeved on the outer wall of the fixed shaft 5, and the two ends of the compression spring 7 are respectively connected to the slider 6 and the elastic groove 4.

[0030] The clamping block has an inclined surface 8 and an arc surface 9 . The inclined surface 8 is arranged in a direction where the clamping block faces away from the winding column 1 , and the arc surface 9 is arranged in a direction where the clamping block faces toward the winding column 1 .

[0031] Through the above technical solution, when the cable is rolled up and placed between two adjacent fixed blocks 2, it first touches the inclined surface 8 of the card block downward, and pushes the card block to retract into the fixed groove 3 through force conduction. When the cable completely enters between the two adjacent fixed blocks 2 and fits the outer edge of the winding column 1, the card block elastically slides out and its arc surface 9 touches the cable and restricts the cable between the two adjacent fixed blocks 2.

[0032] A response groove 10 is provided between two adjacent fixed blocks 2. The response groove 10 is opened on the winding column 1. A response block 11 is slidably connected in the response groove 10. A spring 12 is provided in the response groove 10. The two ends of the spring 12 are respectively connected to the response groove 10 and the response block 11. The response block 11 is connected to the card block.

[0033] Through the above technical solution, the cable's own gravity is used to suppress the response block 11, and the connection between the response block 11 and the card block is relied upon to force the card block downward, thereby further increasing the restraining force on the cable in conjunction with the original card block's squeezing of the cable.

[0034] The card block is composed of a card plate 13 and a special-shaped plate 14, wherein the inclined surface 8 and the arc surface 9 are both arranged on the special-shaped plate 14, the card plate 13 is fixedly connected to the slider 6, the card plate 13 has a rectangular groove 15, the rectangular groove 15 is slidably connected to a T-shaped block 16, the T-shaped block 16 passes through the rectangular groove 15 and is fixedly connected to the special-shaped plate 14, the T-shaped block 16 is bonded with a rubber layer 17, the rubber layer 17 is connected to the first wire 18, and the other end of the first wire 18 passes through the fixed block 2 and the winding column 1 and is connected to the response block 11.

[0035] A control groove 19 is opened in the center of the winding column 1, and a horizontal shaft 20 is fixedly connected to the center of the control groove 19. A ring 21 is slidably sleeved on the horizontal shaft 20, and a second wire 22 is connected to the outer edge of the ring 21. The second wire 22 passes through the winding column 1 and the fixed block 2 in sequence and is connected to the slider 6 along the direction of the virtual center axis of the fixed shaft 5.

[0036] One end of the collar 21 is fixedly connected to a disc 23, and the disc 23 is fixedly connected to a handle 24. A torsion spring 25 is provided in the control groove 19. The torsion spring 25 is sleeved on the horizontal shaft 20 and its two ends are respectively connected to the collar 21 and the horizontal shaft 20.

[0037] Working principle:

[0038] When winding the cable, the user manually wraps the cable in a loop and then snaps the cable toward the space between two adjacent fixing blocks 2. The cable that falls between the two adjacent fixing blocks 2 is pressed down first to touch the inclined surface 8 of the special-shaped plate 14, causing the special-shaped plate 14 and the clamping plate 13 to slide into the fixing groove 3.

[0039] When the special-shaped plate 14 and the clamping plate 13 slide into the fixing groove 3, the area between the two adjacent fixing blocks 2 can accommodate the entry of the cable. After the cable is completely inserted, the downward pressure on the inclined surface 8 of the special-shaped plate 14 is released. Then, the arc surface 9 of the special-shaped plate 14 continues to squeeze the cable under the elastic force of the compression spring 7, so as to ensure that the position of the cable between the two adjacent fixing blocks 2 is stable.

[0040] At the same time, when the cable completely enters between the two adjacent fixed blocks 2 and fits on the winding column 1, the response block 11 is completely pressed into the response groove 10. The response block 11 pulls the T-block 16 downward through the first wire 18 and then applies a downward pulling force to the special-shaped plate 14, prompting the special-shaped plate 14 to apply downward pressure to the squeezed cable.

[0041] When taking it out for use, hold the handle 24 and rotate it in any direction to rotate the ring 21, so that the second wire 22 is wound around the ring 21 and then the second wire 22 is contracted. The contraction of the second wire 22 pulls the slider 6 to cause the clamping plate 13 and the special-shaped plate 14 to move into the fixed groove 3 until the restriction on the cable is lifted, and then it can be taken out for use directly.

[0042] It should be noted that:

[0043] The arrangement of the response slot 10 , the response block 11 and the spring 12 should follow the rule that when the response block 11 does not bear the weight of the cable, the spring 12 can push the top part of the response block 11 out of the response slot 10 .

[0044] The elastic force of the spring 12 and the elastic force of the compression spring 7 should follow the rule: in order to ensure that the cable is stable between two adjacent fixed blocks 2, the elastic force of the spring 12 needs to be much smaller than the elastic force of the compression spring 7, so as to avoid the elastic force of the spring 12 being too large and causing the cable to be pushed out.

[0045] When the first wire 18 and the second wire 22 pass through the solid structure, a sliding channel is left, which facilitates pulling the special-shaped plate 14 through the first wire 18 and pulling the clamping plate 13 and the special-shaped plate 14 through the second wire 22.

[0046] The idea of this application is to:

[0047] In response to the actual situation that cables of existing bus charging piles often drag on the ground, an improvement is made. A winding column 1 is set on the side of the charging pile body. The cable can be wound on the winding column 1 in the form of multiple layers in a circle, and at the same time, it is buckled between two adjacent fixed blocks 2 to squeeze and limit the cable to stabilize its position. The cable's own gravity can also be used to increase the squeezing force of the cable. In this way, regardless of the wind force in the weather or the scratching of the charging pile by the car, the cable will drag on the ground. The size of the winding column 1 itself, the number of fixed blocks 2 set on the winding column 1, and the distance between the connected fixed blocks 2 can all be adaptively adjusted. They can be set before leaving the factory according to parameters such as the amount of vacant area in car charging stations in different regions, the size of the car charging pile itself, and the length and diameter of the cable itself.

[0048] Reference Attachment Figure 1 , where the cable is coiled on the winding column 1, and the charging head is not shown. If the bus charging pile has a matching interface for the charging head, the charging head is installed in the interface. If the bus charging pile does not have a matching interface for the charging head, the charging head will naturally hang beside the pile body and be pulled by the cable.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
