Description

Technical Field

[0002] The car charging terminal, also known as the charging pile, is a power supply device arranged outdoors or in a public parking lot for charging electric vehicles. At present, most of the charging piles on the market are equipped with a bracket inside the shell, the power module is installed on the bracket, and the bracket and the power module on the bracket are encapsulated and protected by the shell. Due to the large number of power module components in the charging pile, in order to meet the installation of the power module, multiple compartments are often set on the bracket to arrange different types of electrical components. When wiring, the cables connected by the electrical components are mostly extended from the edge of the bracket and connected to other components. The extended cables are very likely to block the electrical components in the adjacent compartments, making it difficult to disassemble and maintain the electrical components in the adjacent compartments. In addition, in the above-mentioned charging pile structure, the cables are mostly exposed. When the operator is repairing or disassembling the charging pile, it is very easy to pull the cables due to misoperation, causing the wiring of the non-operating part to be disconnected, thereby interfering with the normal progress of the maintenance or disassembly operation.

[0026] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0027] Please combine Figure 1-6 The utility model discloses a car charging terminal with cables arranged along a preset path, which is easy to maintain and disassemble. The car charging terminal includes a housing 100, a limit bracket 200, a first circuit module 300, a second circuit module 400 and a charging assembly 500. The outer surface of the housing 100 is provided with a gun head plug slot 110, which is used to plug in a charging gun to fix the charging gun, so as to avoid damage to the charging gun caused by dropping the charging gun on the ground. The limit bracket 200 is accommodated in the inner cavity of the housing 100 and fixed to the inner wall of the housing 100. The limit bracket 200 divides the inner wall of the housing 100 to form a plurality of installation areas 210. The limit bracket 200 is provided with a wiring channel, and the limit bracket 200 is provided with a plurality of wire inlets 220 connected to the wiring channel, and the lower part of the limit bracket 200 is provided with a threading hole connected to the wiring channel. The first circuit module 300 includes a plurality of circuit elements located in each installation area 210 and fixedly connected to the inner wall of the housing 100, and each circuit element is electrically connected through a first connection line 230 that passes through the wire inlet 220 and is received in the wiring channel. The second circuit module 400 is located below the limit bracket 200 and is electrically connected to the first circuit module 300 through a second connection line 240 that passes through a wire hole and is inserted into the wiring channel. The charging assembly 500 includes a gun line 510 that passes through the housing 100 and is electrically connected to the output end of the second circuit module 400, and a charging gun 520 that is located outside the housing 100 and is electrically connected to the end of the gun line 510. In this embodiment, the circuit elements of the first circuit module 300 include a monitoring board, a switching power supply, an electric meter, a water immersion sensor, an insulation monitoring box, a temperature sensor, a connection terminal, a leakage switch, and a relay; the second circuit module 400 includes a substrate fixed on the side panel, a PTC heater installed on the substrate, a shunt, a fuse, and a high-voltage DC contactor. The components on the second circuit module 400 are fixed on the substrate by spot welding to form a whole, and the components can be connected by wires printed on the substrate. In other embodiments, the circuit elements of the first circuit module 300 can also select corresponding devices according to the specific structure of the circuit, and the components on the substrate of the second circuit module 400 can also be adjusted as needed, which will not be repeated here.

[0028] In this embodiment, each circuit element of the first circuit module 300 is respectively accommodated in the corresponding installation area 210. When wiring, the first connecting wire 230 passes through the wiring channel and is connected to the corresponding circuit element through the wire inlet 220. In this way, except for the exposed part of the first connecting wire 230 between the circuit element and the wire inlet 220, the rest of the first connecting wire 230 is stored in the wiring channel, so as to separate the first connecting wire 230 from the internal space of the housing 100, so as to reduce the shielding of the circuit element by the arrangement or hanging of the first connecting wire 230. In addition, by adjusting the position of the circuit element, so that the wiring part of the circuit element is as close as possible to the corresponding wire inlet 220, the exposed length of the first connecting wire 230 can be further shortened to reduce the influence of wiring on the disassembly and maintenance of the equipment. The second connecting wire 240 passes through the threading hole at the bottom of the limiting bracket 200 and connects the second circuit module 400 and the first circuit module 300. The second connecting wire 240 is only exposed between the wiring part of the second circuit module 400 and the threading hole, which reduces the exposed length of the second connecting wire 240. During actual installation, the wiring part of the second circuit module 400 can be set at the upper part of the second circuit module 400 to further shorten the exposed length of the second connecting wire 240 and reduce the shielding of the device by the second connecting wire 240. In addition, through the above design, the contact between the operator and the first connecting wire 230 and the second connecting wire 240 during disassembly and maintenance operations can be reduced, avoiding the problem of wiring being pulled off due to misoperation.

[0029] In one embodiment, the automobile charging terminal further includes a partition plate 600 accommodated in the inner cavity of the housing 100, the partition plate 600 is fixedly connected to the inner wall of the housing 100, the partition plate 600 divides the inner cavity of the housing 100 to form a first installation cavity 610 and a second installation cavity 620 located below the first installation cavity 610, and a through hole connected to the threading hole is provided on the partition plate 600. In this embodiment, the partition plate 600 is fixedly connected to the inner wall of the housing 100 by screws, or the partition plate 600 and the housing 100 are integrally formed. By providing the partition plate 600, on the one hand, the first circuit module 300 and the second circuit module 400 can be separated, and on the other hand, the partition plate 600 can also support the limit bracket 200 to prevent the limit bracket 200 from falling from the inner wall of the housing 100.

[0030] Further, the housing 100 includes two side panels 120 arranged opposite to each other, a back panel 130 fixedly connected to the rear side surfaces of the two side panels 120, a front panel 140 fixedly connected to the front side surfaces of the two side panels 120, a top panel 150 fixedly connected to the top surfaces of the two side panels 120, a bottom panel 160 fixedly connected to the bottom surfaces of the two side panels 120, a limit bracket 200, a first circuit module 300 and a second circuit module 400 are fixed on the inner wall of the same side panel 120, and an inspection door 170 is provided on the other side panel 120. In this embodiment, the front panel 140 is located on the main surface of the housing 100, and the back panel 130 is located on the back surface of the housing 100. The main surface of the housing 100 refers to the side of the vehicle charging terminal facing the user when in use, and the back surface of the housing 100 refers to the side of the vehicle charging terminal facing away from the user when in use, and the two side panels 120 are located on the left and right sides of the housing 100. The two side panels 120, the front panel 140, the back panel 130, the top panel 150 and the bottom panel 160 are fixed by screws to enclose a rectangular cavity, which is further divided into two parts, upper and lower, by the partition plate 600. In this embodiment, the front panel 140 is partially recessed to form a gun tip plug slot 110. In other embodiments, a socket connected to the inner cavity of the housing 100 is provided on the front panel 140, and a cover plate with a vertical cross-section of a U-shaped structure is installed at the socket to form the gun tip plug slot 110. In this way, the gun tip plug slot 110 is separated from the inner cavity of the housing 100 to prevent rainwater from entering the inner cavity of the housing 100 through the gun tip plug slot 110.

[0031] In one embodiment, the side plate 120 where the limit bracket 200 is located is the first side plate, and the side plate 120 where the inspection door 170 is located is the second side plate. In order to realize the setting of the inspection door 170, an inspection port 171 is provided on the second side plate, and the inspection port 171 is in a rectangular structure, so that the second side plate is in a ring structure, and one side edge of the inspection door 170 is hingedly connected to the edge of the inspection port 171 to form a hinge connection part, and the opposite side of the inspection door 170 on the side where the hinge connection part is located (i.e., the movable end of the inspection door 170) can be rotated around the hinge connection part as the center, so that the operator can inspect the equipment and components inside the housing 100 through the inspection port 171, and after the inspection or installation work is completed. When the inspection door 170 is closed, the movable end of the inspection door 170 is locked with the edge of the inspection port 171 to prevent irrelevant people or objects from entering the housing 100, thereby causing a safety accident, and prevent the electrical components in the housing 100 from being damaged. It should also be noted that, in the present embodiment, a limiting groove 172 surrounding the inspection opening 171 is provided on the second side panel, and a sealing ring is provided on the edge of the limiting groove 172, and a limiting protrusion is provided on a side of the inspection door 170 corresponding to the inner cavity of the casing 100, and the outer contour shape of the limiting protrusion is adapted to the inner contour shape of the limiting groove 172. In this way, when the inspection door 170 is closed, the mutual constraint between the limiting protrusion and the limiting groove 172 can reduce the shaking of the inspection door 170 and extend the path for dust and rainwater to enter the inner cavity of the casing 100; by providing a sealing ring, the sealing performance of the connection between the inspection door 170 and the second side panel is further improved, thereby preventing rainwater from entering the inner cavity of the casing 100.

[0032] The limiting bracket 200 includes two vertically arranged square tubes 250 disposed opposite to each other, a first horizontal square tube 260 fixedly connected to the tops of the two vertically arranged square tubes 250, a second horizontal square tube 270 fixedly connected to the bottoms of the two vertically arranged square tubes 250, and at least one third horizontal square tube 280 located between the first horizontal square tube 260 and the second horizontal square tube 270 and fixedly connected to the two vertically arranged square tubes 250 respectively. The vertically arranged square tubes 250 extend along the height direction of the side plate 120. The vertically arranged square tubes 250, the first horizontal square tube 260, the second horizontal square tube 270, and the third horizontal square tube 280 together enclose a plurality of installation areas 210. When the number of the third horizontal square tubes 280 is one, the limiting bracket 200 has a structure in the shape of the Chinese character 'Ri'; when the number of the third horizontal square tubes 280 is two, the limiting bracket 200 has a structure in the shape of the Chinese character 'Mu'; when the number of the third horizontal square tubes 280 is greater than or equal to three, the limiting bracket 200 has a ladder-like structure. In this embodiment, the inner cavities of the vertically arranged square tubes 250, the first horizontal square tube 260, the second horizontal square tube 270, and the third horizontal square tube 280 are used to form wiring channels for encapsulating the first connecting wire 230 and the second connecting wire 240. By enclosing a plurality of installation areas 210 with the above-mentioned square tubes and arranging the circuit components in the installation areas 210, on the one hand, the separation of the circuit components is realized, which can prevent the confusion of the first connecting wires 230 connecting the circuit components and reduce the difficulty of arranging the circuit components. On the other hand, the circuit components are respectively arranged in the corresponding installation areas 210. During disassembly, assembly, and maintenance operations, the operator can quickly lock the positions of the circuit components to be processed, thereby improving the disassembly, assembly, and maintenance efficiency of the circuit components. In addition, when the connection between the circuit component and the side plate 120 becomes loose and the circuit component slides along the inner surface of the side plate 120, the third horizontal square tube 280 can also support the circuit component to avoid problems such as disconnection of the wiring and damage of the device caused by the falling of the circuit component, so as to ensure the normal use of the vehicle charging terminal. In this embodiment, the vertically arranged square tubes 250, the first horizontal square tube 260, the second horizontal square tube 270, and the third horizontal square tube 280 are connected by welding or screws. The ends of the third horizontal square tubes 280 are fixed on the side walls of the vertically arranged square tubes 250 and communicate with the inner cavities of the vertically arranged square tubes 250. The bottom openings of the vertically arranged square tubes 250 form wire passing holes.

[0033] Furthermore, in this embodiment, the lower surface of the second transverse square tube 270 abuts against the upper surface of the partition plate 600, so that the partition plate 600 is also used to support the limit bracket 200 to prevent the limit bracket 200 from falling off the side plate 120. Further preferably, the second transverse square tube 270 is screwed or welded to the partition plate 600 to improve the stability of the connection between the two. The automobile charging terminal also includes a heat dissipation module 700 accommodated in the inner cavity of the casing 100 and located below the second circuit module 400. A plurality of heat dissipation holes 710 are provided on the two side panels 120 at positions corresponding to the heat dissipation modules 700. The outer surface of the side panels 120 is also provided with a plurality of arc-shaped baffles 720 fixed one by one at each heat dissipation hole 710. The upper portion of the arc-shaped baffle 720 is fixedly connected to the upper edge of the heat dissipation hole 710, and the lower portion of the arc-shaped baffle 720 is spaced a preset distance from the heat dissipation hole 710. In this way, while ensuring that the heat in the casing 100 can be discharged through the heat dissipation holes 710, the heat dissipation holes 710 can be protected to prevent rainwater from entering the inner cavity of the casing 100 through the heat dissipation holes 710.

[0034] In this solution, the car charging terminal can be controlled in a variety of alternative ways. In one embodiment, a display screen 141, an indicator light 142 and a control switch 143 electrically connected to the first circuit module 300 are installed on the front panel 140. Preferably, the display screen 141 and the indicator light 142 are electrically connected to the monitoring board, respectively, and the control switch 143 is electrically connected to the switch power supply. The display screen 141 is a touch screen, and the indicator light 142 is arranged above the display screen 141. The shape of the indicator light 142 can be a bar, a circle, a star, a petal, a square, a regular pentagon or other irregular shapes; the control switch 143 is arranged beside the display screen 141, and the setting height of the control switch 143 and the display screen 141 is close. The setting height of the two is preferably such that the operator's hand can touch the display screen 141 and the control switch 143 when the upper arm is hanging down, so as to adapt to the height of the operator and reduce the difficulty of operation. In another embodiment, the inner cavity of the casing 100 is also provided with a communication module electrically connected to the monitoring board of the first circuit module 300, and the communication module is communicatively connected to the third-party operating platform. A QR code is attached to the front panel 140 of the casing 100. The operator can enter the corresponding APP interface by scanning the QR code and send instructions in the APP interface to draw power from the car charging terminal.

[0035] Please combine Figure 2-6The vehicle charging terminal also includes a gun line storage assembly 800, which includes a capstan 810 housed in the inner cavity of the housing 100 and fixedly connected to the top plate 150, a spring (not shown) mounted on the capstan 810, a limit rope 820, and a pulley 830 mounted on the outer wall of the side plate 120. One end of the limit rope 820 is fixed to the free end of the spring, and the other end of the limit rope 820 is wound around the pulley 830 and fixed on the gun line 510. By providing the gun line storage assembly 800, when the charging gun 520 is inserted into the gun head plug slot 110, the gun line 510 is driven by the limit rope 820 to rise, so as to avoid the problem that the gun line 510 is crushed by the vehicle due to the gun line 510 falling on the ground, and to prevent the gun line 510 from being damaged. When the vehicle needs to be charged, the operator pulls out the charging gun 520 from the gun head plug slot 110 and pulls the gun line 510. At this time, the gun line 510 will drive the end of the limit rope 820 to drop, and the free end of the clockwork spring is pulled, so that the elastic potential energy of the clockwork spring increases, so that after charging is completed, the clockwork spring drives the limit rope 820 and the gun line 510 to reset, thereby realizing the suspension protection of the gun line 510.

[0036] In addition, the automobile charging terminal further includes a mounting frame 900 located in the first mounting cavity 610, the mounting frame 900 includes two first connecting plates 910 arranged opposite to each other and fixedly connected to the side plates 120 respectively, a second connecting plate 920 located on one side of the first connecting plate 910 adjacent to the inspection door 170 and fixedly connected to the two first connecting plates 910 respectively, and the limiting bracket 200 and the first circuit module 300 are fixed on the second connecting plate 920. In other words, the cross section of the mounting frame 900 is a U-shaped structure, so that the distance from the limiting bracket 200 and the first circuit module 300 to the first side plate is extended, in other words, the distance from the first circuit module 300 to the inspection door 170 is shortened, and the problem that the operator needs to put his head and hands into the inner cavity of the housing 100 to operate due to the insufficient operating distance caused by the long distance between the inspection door 170 and the first circuit module 300 is avoided, and the difficulty of the operator to operate and handle the first circuit module 300 after opening the inspection door 170 is reduced.

[0037] In one embodiment, the automobile charging terminal further includes a base 180 disposed at the bottom of the bottom plate 160, and a weight-reducing groove is provided on the lower surface of the base 180. By providing the base 180, the horizontal height of the bottom plate 160 is raised, and the leakage accident caused by the rainwater in the charging site penetrating into the housing 100 through the bottom plate 160 of the housing 100 can be avoided, so as to improve the safety of the automobile charging terminal. Furthermore, a fixing frame 190 is also provided on the bottom plate 160, and the heat dissipation module 700 is installed on the top of the fixing frame 190 to further raise the horizontal height of the heat dissipation module 700 and avoid the heat dissipation module 700 from contacting the rainwater penetrating into the inner cavity of the housing 100 as much as possible.

[0038] The automobile charging terminal of the utility model is implemented by setting a limit bracket 200 on the inner wall of the housing 100. The limit bracket 200 is used to limit the position of the circuit element of the first circuit module 300 on the one hand, and on the other hand, the limit bracket 200 is also provided with a wiring channel for accommodating the first connecting line 230 and the second connecting line 240. In this way, the first connecting line 230 and the second connecting line 240 are arranged along a preset path, which can avoid the first connecting line 230 and the second connecting line 240 from blocking the circuit element, thereby reducing the disassembly of the circuit element. and maintenance difficulty; when the first connecting line 230 and the second connecting line 240 are arranged along the wiring channel of the limiting bracket 200, the second circuit module 400 is arranged close to the first circuit module 300, and the threading hole is opened at the bottom of the limiting bracket 200, which shortens the exposed length of the second connecting line 240, reduces the pulling of the first connecting line 230 and the second connecting line 240 during disassembly and maintenance, and prevents the first connecting line 230 and the second connecting line 240 from being disconnected due to misoperation, so as to ensure the normal progress of maintenance and disassembly operations.
