[0056] A charging pile is a charging device for charging electric vehicles, which can be fixed on the ground or wall. The charging pile includes a shell, an incoming cable and an outgoing cable, both of which extend into the shell. The incoming cable is used to transmit the power from the power grid to the charging pile, and the outgoing cable is used to transmit the power from the charging pile to the battery of the electric vehicle.

[0057] In the related art, charging piles usually only come with outgoing cables when they leave the factory, and the incoming cables need to be installed by the user. The housing includes a bottom shell and a panel, and the outgoing cables extend into the bottom shell. The side of the bottom shell facing away from the panel also has a wiring slot and a back panel. The user needs to open the back panel and install one end of the incoming cable into the wiring slot. However, this brings great difficulty to the user.

[0058] In view of the above technical problems, the present disclosure provides a charging pile, such as Figures 1 - 4As shown in the figure, the charging pile includes a bottom case 1, a panel 2, a first wire pressing plate 3, a second wire pressing plate 4, a first cable 5 and a second cable 6. The bottom case 1 includes a bottom wall 1a and a plurality of side walls 1b. One side of the plurality of side walls 1b is connected to the bottom wall 1a, and the other side is connected to the panel 2. An accommodation cavity 10 for accommodating the first wire pressing plate 3 and the second wire pressing plate 4 is formed among the bottom wall 1a, the plurality of side walls 1b and the panel 2. The lower side of the side wall 1b includes a first wire passing hole 1c and a second wire passing hole 1d. The first wire passing hole 1c and the second wire passing hole 1d are arranged along the thickness direction, and the thickness direction is the direction from the bottom wall 1a to the panel 2. The bottom wall 1a, the first wire pressing plate 3 and the second wire pressing plate 4 are sequentially connected along the thickness direction. The first cable 5 passes through the first wire passing hole 1c, and the first cable 5 is clamped between the first wire pressing plate 3 and the bottom wall 1a. The second cable 6 passes through the second wire passing hole 1d, and the second cable 6 is clamped between the first wire pressing plate 3 and the second wire pressing plate 4. Among them, one of the first cable 5 and the second cable 6 is an incoming cable, and the other is an outgoing cable.

[0059] Among them, the side wall 1b also has a hanging hole 100. When the user does not use the charging pile, the charging gun can be inserted into the hanging hole 100.

[0060] The first cable 5 can be an incoming cable or an outgoing cable, and the embodiments of the present disclosure do not make specific limitations on this. The length of the incoming cable is about 1m. One end of the incoming cable is connected to the circuit breaker, and the circuit breaker is also used to connect to the power grid. If the length of the incoming cable is short, the position of the circuit breaker can be moved so that the incoming cable can be connected to the circuit breaker.

[0061] The first cable 5 and the second cable 6 include a wire core and an epidermis. The epidermis is wrapped outside the wire core, and the epidermis can be made of rubber or silica gel.

[0062] According to the technical solution provided by the embodiments of the present disclosure, both the first cable 5 and the second cable 6 are located inside the accommodation cavity 10, that is, the charging pile comes with an incoming cable and an outgoing cable. In this way, the user does not need to install the incoming cable by himself, thereby reducing the user's usage difficulty. Moreover, the first cable 5 and the second cable 6 are arranged along the thickness direction of the charging pile, so that the space occupied by the first cable 5 and the second cable 6 in the width direction of the charging pile is small, which is beneficial to arranging other devices in the width direction of the charging pile.

[0063] In some examples, such as Figure 4As shown in the figure, the bottom case 1 includes a fixing base 11. One side of the fixing base 11 facing the panel 2 has a first groove 111, and one side of the first wire pressing plate 3 facing the bottom wall 1a has a second groove 31. The first cable 5 is clamped between the first groove 111 and the second groove 31. When installing the first cable 5, the first groove 111 and the second groove 31 can limit the position of the first cable 5, ensure that the first cable 5 can be installed at the specified position, and also enable the first cable 5 to be stably clamped between the first wire pressing plate 3 and the bottom case 1. Among them, the fixing base 11 and the bottom case 1 can be an integral structure.

[0064] Correspondingly, one side of the first wire pressing plate 3 facing the panel 2 has a third groove 32, and one side of the second wire pressing plate 4 facing the bottom wall 1a has a fourth groove 41. The second cable 6 is clamped between the fourth groove 41 and the third groove 32. Similarly, when installing the second cable 6, the third groove 32 and the fourth groove 41 can limit the position of the second cable 6, ensure that the second cable 6 can be installed at the specified position, and also enable the second cable 6 to be stably clamped between the first wire pressing plate 3 and the second wire pressing plate 4.

[0065] Exemplarily, the first through hole formed by the first groove 111 and the second groove 31 can be aligned with the first wire threading hole 1c, so that the first cable 5 is not easily twisted between the first wire threading hole 1c and the first through hole, thereby making the first cable 5 not easily damaged. Correspondingly, the second through hole formed by the fourth groove 41 and the third groove 32 can be aligned with the second wire threading hole 1d, so that the second cable 6 is not easily twisted between the second wire threading hole 1d and the second through hole, thereby making the second cable 6 not easily damaged.

[0066] Next, an exemplary description of the implementation manner in which the fixing base 11 and the first wire pressing plate 3 clamp the first cable 5 is given.

[0067] In some examples, as Figure 5 shown, the fixing base 11 includes at least one first wire pressing rib 1101 and at least one second wire pressing rib 1102. The first wire pressing rib 1101 and the second wire pressing rib 1102 are alternately arranged along the axial direction of the first groove 111, and the first groove 111 penetrates through the first wire pressing rib 1101 and the second wire pressing rib 1102. One side of the first wire pressing rib 1101 facing the panel 2 is arc-shaped, and one side of the second wire pressing rib 1102 facing the panel 2 is serrated, and the serrations of the second wire pressing rib 1102 protrude in the direction close to the panel 2 relative to the first wire pressing rib 1101.

[0068] The serrations of the second wire pressing rib 1102 can be embedded into the skin of the first wire cable 5 to prevent the first wire cable 5 from moving due to external forces. The second wire pressing rib 1102 can press the skin of the first wire cable 5, making the skin of the first wire cable 5 evenly stressed. By arranging the first wire pressing rib 1101 and the second wire pressing rib 1102 alternately, while preventing the first wire cable 5 from moving due to external forces, it can also reduce the damage to the skin of the first wire cable 5 caused by the serrations on the second wire pressing rib 1102.

[0069] In some examples, such as Figures 5 - 7 shown, the fixing seat 11 includes a plurality of first pressing plates 110a, and the first groove 111 penetrates through the plurality of first pressing plates 110a. The first wire pressing plate 3 includes a plurality of second pressing plates 30a, and the second groove 31 penetrates through the plurality of second pressing plates 30a. At least one first pressing plate 110a and at least one second pressing plate 30a are arranged staggeredly.

[0070] In this way, the pressing positions of the fixing seat 11 and the first wire pressing plate 3 on the first wire cable 5 can be different, making the pressing force on the first wire cable 5 more dispersed. In this way, it can not only strengthen the pressing effect on the first wire cable 5, but also avoid the first wire cable 5 being damaged due to overly concentrated stress.

[0071] Among them, some of the first pressing plates 110a are the first wire pressing ribs 1101, and the other part of the first pressing plates 110a are the second wire pressing ribs 1102. The sides of the plurality of second pressing plates 30a facing the bottom wall 1a are all serrated.

[0072] In some examples, such as Figure 5 shown, the fixing seat 11 further includes a plurality of first reinforcing ribs 110b. At least one first reinforcing rib 110b is connected between two adjacent first pressing plates 110a. The first reinforcing rib 110b can support the first pressing plate 110a. When the first wire cable 5 is subjected to external forces, under the action of the first reinforcing rib 110b, the first pressing plate 110a is not easily pulled and deformed by the first wire cable 5, so that the first pressing plate 110a is not easily damaged, strengthening the clamping effect on the first wire cable 5.

[0073] Next, an exemplary description will be given of the implementation manner in which the first wire pressing plate 3 and the second wire pressing plate 4 clamp the second wire cable 6.

[0074] In some examples, such as Figure 8As shown in the figure, the first pressing plate 3 includes at least one third pressing rib 301 and at least one fourth pressing rib 302. The third pressing ribs 301 and the fourth pressing ribs 302 are alternately arranged along the axial direction of the third groove 32, and the third groove 32 penetrates through the third pressing ribs 301 and the fourth pressing ribs 302. The side of the third pressing rib 301 facing the panel 2 is arc-shaped, the side of the fourth pressing rib 302 facing the panel 2 is serrated, and the serrations of the fourth pressing rib 302 protrude in the direction close to the panel 2 relative to the third pressing rib 301.

[0075] As Figure 9 shown in the figure, the second pressing plate 4 includes at least one fifth pressing rib 401 and at least one sixth pressing rib 402. The fifth pressing ribs 401 and the sixth pressing ribs 402 are alternately arranged along the axial direction of the fourth groove 41, and the fourth groove 41 penetrates through the fifth pressing ribs 401 and the sixth pressing ribs 402. The side of the fifth pressing rib 401 facing the bottom wall 1a is arc-shaped, the side of the sixth pressing rib 402 facing the bottom wall 1a is serrated, and the serrations of the sixth pressing rib 402 protrude in the direction close to the bottom wall 1a relative to the fifth pressing rib 401.

[0076] The serrations of the fourth pressing rib 302 and the serrations of the sixth pressing rib 402 can be embedded into the skin of the second cable 6 to prevent the second cable 6 from moving due to external force. The third pressing rib 301 and the fifth pressing rib 401 can press the skin of the second cable 6 and make the skin of the second cable 6 receive uniform force. By alternately arranging the third pressing ribs 301 and the fourth pressing ribs 302, and alternately arranging the fifth pressing ribs 401 and the sixth pressing ribs 402, while preventing the second cable 6 from moving due to external force, it is also possible to reduce the damage to the skin of the second cable 6 caused by the serrations on the serrations of the fourth pressing rib 302 and the sixth pressing rib 402.

[0077] In some examples, as Figures 7 - 9 shown in the figure, the first pressing plate 3 includes a plurality of third pressing plates 30b, and the third groove 32 penetrates through the third pressing plates 30b. The second pressing plate 4 includes a plurality of fourth pressing plates 40a, and the fourth groove 41 penetrates through the fourth pressing plates 40a. At least one third pressing plate 30b and at least one fourth pressing plate 40a are arranged staggeredly.

[0078] In this way, it can be ensured that the pressing positions of the first pressing plate 3 and the second pressing plate 4 on the second cable 6 are different, so that the pressing force received by the second cable 6 is relatively dispersed. In this way, not only can the pressing effect on the second cable 6 be strengthened, but also the situation that the second cable 6 is damaged due to too concentrated force can be avoided.

[0079] Among them, part of the third pressing plate 30b is the third wire pressing rib 301, and the other part of the third pressing plate 30b is the fourth wire pressing rib 302. Part of the fourth pressing plate 40a is the fifth wire pressing rib 401, and the other part of the fourth pressing plate 40a is the sixth wire pressing rib 402.

[0080] In some examples, as Figure 8 shown, the first wire pressing plate 3 further includes a plurality of third reinforcing ribs 30c, and at least one third reinforcing rib 30c is connected between every two adjacent third pressing plates 30b. The third reinforcing rib 30c can support the third pressing plate 30b. When the second cable 6 is subjected to an external force, under the action of the third reinforcing rib 30c, the third pressing plate 30b is not easily pulled and deformed by the second cable 6.

[0081] Correspondingly, as Figure 9 shown, the second wire pressing plate 4 further includes a fourth reinforcing rib 40b, and at least one fourth reinforcing rib 40b is connected between every two adjacent fourth pressing plates 40a. The fourth reinforcing rib 40b can support the fourth pressing plate 40a. When the second cable 6 is subjected to an external force, under the action of the fourth reinforcing rib 40b, the fourth pressing plate 40a is not easily pulled and deformed by the second cable 6. In this way, the clamping effect of the first wire pressing plate 3 and the second wire pressing plate 4 on the second cable 6 can be strengthened.

[0082] Next, an exemplary description will be given of the connection method between the bottom shell 1, the first wire pressing plate 3, and the second wire pressing plate 4.

[0083] In some examples, as Figures 8 - 10 shown, the first wire pressing plate 3 has a first fixing post 33, the second wire pressing plate 4 has a first guiding groove 42, and the first fixing post 33 is located in the first guiding groove 42. The first fixing post 33 has a first threaded hole 330, the second wire pressing plate 4 has a first mounting hole 40, the first mounting hole 40 communicates with the guiding groove 42 and is opposite to the first threaded hole 330, and the charging pile further includes a first bolt 7, and the first bolt 7 passes through the first mounting hole 40 and the first threaded hole 330.

[0084] When installing the first wire pressing plate 3 and the second wire pressing plate 4, the first guiding groove 42 can play a guiding role, so that the first mounting hole 40 and the first threaded hole 330 can be quickly aligned. The first wire pressing plate 3 and the second wire pressing plate 4 are connected by the first bolt 7, which can strengthen the connection strength between the first wire pressing plate 3 and the second wire pressing plate 4. Moreover, by adjusting the tightening degree of the first bolt 7, the clamping force of the first wire pressing plate 3 and the second wire pressing plate 4 on the second cable 6 can be adjusted. In addition, when the second cable 6 needs to be replaced, the second wire pressing plate 4 can be separated from the first wire pressing plate 3 by loosening the bolt, so as to take out the second cable 6.

[0085] Exemplarily, as Figure 9As shown, the side wall of the first guiding groove 42 has an avoidance opening 421 for avoiding the connecting rib 35 between the first fixing post 33 and the third groove 32.

[0086] As Figure 8 shown, the first pressing plate 3 may have two first fixing posts 33, and the two first fixing posts 33 are respectively located on both sides of the third groove 32. Correspondingly, as Figure 9 shown, the second pressing plate 4 may have two first guiding grooves 42, and the two first guiding grooves 42 are respectively located on both sides of the fourth groove 41. In this way, the connection force between the first pressing plate 3 and the second pressing plate 4 can be distributed more evenly, so that the clamping force on the second cable 6 is more uniform, and the second cable 6 is not likely to shift.

[0087] In some examples, as Figure 5 、 Figure 6 and Figure 11 shown, the fixing base 11 has a second fixing post 112, the first pressing plate 3 has a second guiding groove 34, and the second fixing post 112 is located in the second guiding groove 34. The second fixing post 112 has a second threaded hole 1120, the first pressing plate 3 has a second mounting hole 30, the second mounting hole 30 communicates with the second guiding groove 34 and is opposite to the second threaded hole 1120. The charging pile further includes a second bolt 8, and the second bolt 8 passes through the second mounting hole 30 and the second threaded hole 1120.

[0088] When installing the first pressing plate 3 on the bottom shell 1, the second guiding groove 34 can play a guiding role, so that the second mounting hole 30 can be quickly aligned with the second threaded hole 1120. The first pressing plate 3 and the fixing base 11 are connected by the second bolt 8, which can make the connection strength between the first pressing plate 3 and the fixing base 11 relatively high. And by adjusting the tightening degree of the bolt, the clamping force of the first pressing plate 3 and the fixing base 11 on the first cable 5 can be adjusted. In addition, when the first cable 5 needs to be replaced, the bolt can be loosened to separate the first pressing plate 3 from the fixing base 11, so as to take out the first cable 5.

[0089] Exemplarily, the fixing base 11 has a plurality of second fixing posts 112, and the plurality of second fixing posts 112 are evenly distributed on both sides of the first groove 111. Correspondingly, the first pressing plate 3 has a plurality of second guiding grooves 34, and the plurality of second guiding grooves 34 are evenly distributed on both sides of the second groove 31. In this way, the connection force between the fixing base 11 and the first pressing plate 3 can be distributed more evenly, so that the clamping force on the first cable 5 is more uniform, and the first cable 5 is not likely to shift.

[0090] In some examples, as Figure 12As shown, the first mounting hole 40, the first threaded hole 330, and the second threaded hole 1120 are opposite to each other, and the first bolt 7 passes through the first mounting hole 40, the first threaded hole 330, and the second threaded hole 1120. In this way, the number of bolts can be reduced, and the assembly process can be simplified, thereby improving the assembly efficiency of the charging pile.

[0091] The above are only optional embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the principle of the present disclosure shall be included within the protection scope of the present disclosure.
