Description

Technical Field

[0001] This utility model relates to the field of new energy electric vehicles, and in particular to a flat wire liquid-cooled charging gun tail cable fixing structure. Background Technology

[0002] With the increasing popularity of electric vehicles, the demand for high-power fast charging is growing daily. Traditional charging guns use round cables, which require liquid cooling structures to improve heat dissipation of the internal wire cores to meet the needs of high-power charging. This results in thicker and heavier cables, making them less convenient to handle and bend. Therefore, flat cables offer better space utilization, a smaller bending radius, and are more flexible and convenient to use. However, the change in cable type also brings new problems, such as cable loosening during use. The original locking structure of round cables is no longer suitable and needs to be redesigned to ensure that the locking structure can both prevent displacement and detachment during shaking and can be repeatedly disassembled and reused. Utility Model Content

[0003] Based on the above, the purpose of this utility model is to provide a cable fixing structure for the tail of a flat wire liquid-cooled charging gun, which meets the fixing requirements of the flat wire liquid-cooled charging gun cable.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A flat wire liquid-cooled charging gun tail cable fixing structure includes a charging gun housing, a flat wire body, a first locking block, and a second locking block, wherein:

[0006] The first locking block is fitted onto the flat wire body and can move along the length direction of the flat wire body. The first locking block is provided with a locking part that extends along the length direction of the flat wire body and the locking part surrounds part of the circumferential surface of the flat wire body.

[0007] The second locking block can be separated from and combined with the first locking block. In the combined state, the second locking block and the locking wire part cooperate to cover the circumferential surface of the flat wire and form a hugging force on the flat wire.

[0008] The first locking block and the second locking block are combined and embedded in the gap between the charging gun housing and the flat wire to fix the flat wire.

[0009] As an alternative, splicing components are provided on both sides of the locking wire and on both sides of the second locking block. The splicing components are used to maintain the first locking block and the second locking block in a combined state.

[0010] As an optional solution, the splicing component includes a slot disposed on one of the locking wire portion and the second locking block, and a locking block disposed on the other of the locking wire portion and the second locking block, wherein the slot and the locking block engage with each other.

[0011] As an alternative, the locking section and the second locking block are arranged in half around the flat wire body.

[0012] As an alternative, locking elements are provided on the outside of the first locking block and the second locking block. The locking elements are used to maintain and strengthen the clamping force of the locking part and the second locking block on the flat wire.

[0013] As an alternative, the locking component includes a fixed latch. The first locking block and the second locking block are combined to form a guide slope on the outer surface. The fixed latch is sleeved on the guide slope and connected to the first locking block by a fastener.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.

[0030] Example 1:

[0031] Please see Figure 1 This embodiment provides a flat wire liquid-cooled charging gun tail cable fixing structure, including a charging gun housing, a flat wire body 1, a first locking block 2, and a second locking block 3, wherein:

[0032] The first locking block 2 is sleeved on the flat wire body 1 and can move along the length direction of the flat wire body 1. The first locking block 2 is provided with a locking part 4 extending along the length direction of the flat wire body 1. The locking part 4 surrounds part of the circumferential surface of the flat wire body 1.

[0033] The second locking block 3 can be separated and combined with the first locking block 2. In the combined state, the second locking block 3 and the locking wire part 4 cooperate to cover the circumferential surface of the flat wire 1 and form a hugging force on the flat wire 1.

[0034] After the first locking block 2 and the second locking block 3 are combined, they are embedded in the gap between the charging gun housing and the flat wire 1 to fix the flat wire 1.

[0035] Therefore, a clamping and locking mechanism was designed to secure the flat wire 1, which has a simple structure. During use, the flat wire 1 can be kept from loosening, the whole structure is not bulky, and it is easy to bend and handle. Furthermore, it is easy to disassemble and inspect during maintenance without damaging parts, and it does not affect secondary assembly and use.

[0036] The flat cable 1 has better bending performance than traditional round cables, and its specific internal structure will not be highlighted here. The first locking block 2 and the second locking block 3 are made of impact-resistant, high-strength, and low-density magnesium alloy to ensure that they do not fail, shake, or crack after being locked. When the second locking block 3 and the first locking block 2 are separate, the first locking block 2 can be adjusted and moved on the flat cable 1 to facilitate adjustment of the fixed position, so that the cable bundle inside the charging gun housing is not wrinkled or squeezed and has a certain amount of room to move. When the second locking block 3 and the first locking block 2 are combined, that is, the first locking block 2 and the second locking block 3 are fixed on the flat cable 1, realizing the cable locking function.

[0037] Optionally, splicing members are provided on both sides of the locking wire portion 4 and on both sides of the second locking block 3. The splicing members are used to maintain the first locking block 2 and the second locking block 3 in a combined state.

[0038] Specifically, the splicing component includes a slot 5 disposed on one of the locking wire part 4 and the second locking block 3, and a locking block 6 disposed on the other of the locking wire part 4 and the second locking block 3. The slot 5 and the locking block 6 engage to achieve a reliable combination of the first locking block 2 and the second locking block 3.

[0039] In particular, the locking part 4 and the second locking block 3 are arranged in half around the flat wire body 1, which facilitates the separation and combination of the second locking block 3.

[0040] To ensure the effective clamping of the wire locking part 4 and the second locking block 3 onto the flat wire body 1, optionally, as follows: Figure 3 As shown, several pressure protrusions 7 are respectively provided on the inner wall of the first locking block 2 and the inner wall of the second locking block 3. The height of the pressure protrusions 7 is set according to the shrinkage characteristics of the outer skin material of the flat wire 1, so that when the flat wire 1 is clamped, the flat wire 1 is not crushed and its internal pipeline is not damaged, while ensuring that the flow rate of the internal coolant is not affected.

[0041] Example 2:

[0042] Please see Figure 1 and Figure 2 This embodiment provides a flat wire liquid-cooled charging gun tail cable fixing structure. Based on the first embodiment, a locking member is provided outside the first locking block 2 and the second locking block 3. The locking member is used to maintain and strengthen the clamping force of the locking part 4 and the second locking block 3 on the flat wire body 1.

[0043] Therefore, the locking mechanism enhances the combined effect of the first locking block 2 and the second locking block 3, further securing the flat wire 1 and ensuring it does not loosen during use.

[0044] Optionally, the locking component includes a fixed latch 8. After the first locking block 2 and the second locking block 3 are combined, a guide slope 9 is formed on the outer surface. The fixed latch 8 is sleeved on the guide slope 9 and connected to the first locking block 2 by a fastener. The fixed latch 8 is used to press the locking part 4 and the second locking block 3 against the flat wire body 1.

[0045] Furthermore, the fastener is a screw, and the fixing latch 8 is provided with a through hole 10. The first locking block 2 is provided with a fixing part 11. The screw passes through the through hole 10 and is threadedly connected to the fixing part 11. In addition, due to the threaded connection, the axial distance between the fixing latch 8 and the second locking block 3 is adjustable, that is, the pressure applied by the fixing latch 8 to the locking part 4 and the second locking block 3 is adjustable, which facilitates the adjustment of the locking force on the flat wire body 1.

[0046] Furthermore, the fixing buckle 8 is embedded in the tail end port of the charging gun housing and fixed to the charging gun housing, thereby fixing the first locking block 2, the second locking block 3, the fixing buckle 8, the flat wire 1 and the charging gun housing together to form an integral unit.

[0047] Example 3:

[0048] This embodiment provides a flat wire liquid-cooled charging gun tail cable fixing structure, including a charging gun housing, a flat wire body 1 and an elastic clamp. The elastic clamp is C-shaped, and quick-release buckles are provided at both ends of the opening of the elastic clamp. The quick-release buckles are used to close the opening of the elastic clamp when the elastic clamp is sleeved on the flat wire body 1, so that the elastic clamp is tightly clamped to the flat wire body 1, and the elastic clamp is embedded in the gap between the charging gun housing and the flat wire body 1, thereby fixing the flat wire body 1.

[0049] Unlike the rigid fixing method in Embodiment 1, this embodiment relies on the elastic hoop deformation to clamp the flat wire 1, which can adapt to the dimensional tolerance of the flat wire 1 and ensure the locking effect. Moreover, the quick-release buckle (similar to a bag buckle) is faster to assemble and more convenient to repeat than the traditional bolt and claw fastening method.

[0050] In summary, the above-mentioned flat wire liquid-cooled charging gun tail cable fixing structure can apply a stable and uniform clamping force to the flat wire body 1, adapt to the flat wire shape (thin and wide characteristics), prevent the flat wire body 1 from loosening or shifting under conditions such as frequent plugging and unplugging of the charging gun, vibration, and temperature changes, ensure the continuous and stable electrical connection, and take into account the ease of assembly and the operability of later maintenance.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
