Description

Technical Field

[0001] The present application relates to the technical field of charging piles, and in particular to a wire taking-up device and a charging pile. Background Art

[0002] A charging pile refers to a charging device that provides energy replenishment for electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or on the wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various models of electric vehicles according to different voltage levels.

[0003] Generally, a charging pile includes a charging cable and a charging gun disposed at the end of the charging cable. In order to ensure the flexibility of the charging gun, the charging cable is generally designed to be longer.

[0004] However, since the charging cable is long, it is easy for the charging cable to be dragged on the ground when the charging gun is moved, which will cause the surface of the charging cable to be worn. In severe cases, the wires inside the charging cable will be exposed, posing a risk of leakage. Utility Model Content

[0005] The purpose of the present application is to provide a wire-retracting device and a charging pile to solve the technical problems that the charging cable is easily aged and leaks when being dragged on the ground during the movement of the charging gun.

[0006] In the first aspect, the utility model provides a wire-winding device, comprising: a fixed base; a swing arm member connected to the fixed base, the swing arm member having a folded position and an extended position, the swing arm member being movable between the folded position and the extended position, the angle between the swing arm member in the folded position and the fixed base being smaller than the angle between the swing arm member in the extended position and the fixed base; a reset component, arranged on the fixed base, the reset component comprising a flexible traction member, one end of the flexible traction member being connected to the swing arm member, the flexible traction member being configured so that the swing arm member has a tendency to reset from the extended position to the folded position; and a hanging member, arranged on the swing arm member, the hanging member being used to hang the charging cable.

[0007] In some embodiments, the reset assembly also includes a reset seat, the other end of the flexible traction member is connected to the reset seat, the reset seat includes a shell and a rope outlet portion, the rope outlet portion is arranged inside the shell or on one side of the shell, and the flexible traction member is connected to the swing arm member through the rope outlet portion.

[0008] In some embodiments, the swing arm member includes a first swing arm portion and a second swing arm portion, the first swing arm portion is connected to the second swing arm portion, and the first swing arm portion is movably connected to the fixed base.

[0009] In some embodiments, there are two swing arm members, and each swing arm member is connected to two first side walls of the fixed base that are oppositely arranged through a connecting member.

[0010] In some embodiments, each first side wall has a first end and a second end in the first direction, the reset assembly is disposed near the first end, and the swing arm member is disposed near the second end.

[0011] In some embodiments, the connecting member includes: a first connecting portion, which is disposed on the first side wall; a second connecting portion, which is disposed on the swing arm member; and a pivot pin, which is pivotally connected to the first connecting portion and the second connecting portion.

[0012] In some embodiments, when the swing arm is in the folded position, the swing arm abuts against the first side wall.

[0013] In some embodiments, the line taking-up device further includes: a connecting column, through which the flexible traction member is connected to the swing arm member.

[0014] In a second aspect, an embodiment of the present application further provides a charging pile, comprising a cabinet and the above-mentioned wire-receiving device, wherein the wire-receiving device is arranged on the top of the cabinet.

[0015] In some embodiments, the charging pile also includes a charging device and a charging cable, one end of the charging cable is connected to the cabinet, and the other end is connected to the charging device.

[0016] The technical effect of the utility model is to provide a wire-retracting device and a charging pile. When the user pulls the charging cable, the swing arm rotates and unfolds under the traction of the charging cable, and the reset assembly can drive the swing arm to automatically move to the folded position, which is convenient to use. During the traction process, since the charging cable is suspended on the suspension member and the charging cable does not contact the ground, the wire-retracting device can avoid the phenomenon of aging and damage caused by the charging cable dragging on the ground, thereby improving the life of the charging device (charging gun).

[0017] Furthermore, the charging pile includes the wire-retracting device. When charging, the user pulls the charging device (which can be called a charging gun) to the charging port of the car, and the swing arm rotates and unfolds under the traction of the charging cable. After the user finishes charging and returns the charging device, the flexible traction member output from the reset component drives the swing arm to rotate, so that the swing arm rotates and resets to the initial position (i.e., the retracted position).

[0018] Since the charging cable is suspended on the swing arm and there is no direct connection between the charging cable and the reset seat of the reset assembly, the swing arm bears part of the weight of the charging cable, so that the charging cable will not be under stress all the time. Therefore, when the user uses the charging device to charge, the swing arm can share the weight of the charging cable, making it easier for the user to pull the charging cable, providing the user with a better charging experience.

[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

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

[0035] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] Most of the charging cables of traditional charging piles are dragged on the ground, which not only makes the gun wire occupy the charging parking space, but also gets stained with dust and dirt. There is a certain distance between the charging pile and the charging car, and the charging cable is long. Users need to drag the charging cable frequently to charge. Since the charging cable is dragged on the ground for a long time, and the charging cable is in direct contact with the concrete or asphalt road, the aging and breakage of the charging cable are accelerated due to the high surface temperature. If the charging gun is used for charging in rainy and snowy weather, there may be a risk of leakage due to the broken skin of the charging cable. There is also a risk of accelerated aging and leakage due to wear of the charging gun cable. In addition, if the charging cable is dragged on the ground for a long time, it may be crushed by the wheels of the charging car, causing damage to the charging cable and the gun head.

[0037] The above-mentioned problems have serious impacts on the user experience, reliability, service life and safety hazards of the charging pile.

[0038] To solve the above problems, Figures 1 to 5As shown, an embodiment of the present application provides a wire-retracting device 100, comprising a fixed base 1, a swing arm member 2, a reset assembly 3 and a suspension member 4. The swing arm member 2 is connected to the fixed base 1, and the swing arm member 2 has a folded position and an unfolded position, and the swing arm member 2 can move between the folded position and the unfolded position. The reset assembly 3 is arranged on the fixed base 1, and the reset assembly 3 includes a flexible traction member 32, and one end of the flexible traction member 32 is connected to the swing arm member 2. The suspension member 4 is arranged on the swing arm member 2, and the suspension member 4 is used to hang the charging cable 400. Therefore, when the user pulls the charging cable 400, the swing arm member 2 will rotate and unfold with the movement of the charging cable 400, and the reset assembly 3 can drive the unfolded swing arm member 2 to automatically move to the folded position, which is more convenient to use. During the pulling process of the charging cable, since the charging cable 400 is suspended on the hanging member 4 and the charging cable 400 does not contact the ground, the wire take-up device 100 can prevent the charging cable 400 from dragging on the ground and causing aging and damage, thereby increasing the life of the charging device 300.

[0039] Furthermore, the charging pile includes the wire-retracting device 100. When charging, the user pulls the charging device 300 to the charging port of the car. As the user pulls the charging cable 400, the swing arm member 2 rotates and then unfolds, so that the charging cable can be close to the car. After the user finishes charging and returns the charging device 300, the flexible traction member 32 in the reset component 3 drives the swing arm member 2 to move, so as to control the swing arm member 2 to achieve reset. In addition, the charging cable 400 is suspended on the swing arm member 2, and the swing arm member 2 can bear a part of the weight of the charging cable 400, so that the user does not have to bear the entire weight of the charging cable 400 when pulling the charging cable 400, making it easier for the user to pull the charging cable 400, providing the user with a better charging experience. A detailed description will be given below.

[0040] In one embodiment, if Figure 1 As shown, an embodiment of the present application provides a wire take-up device 100 and a charging pile. The charging pile includes a wire take-up device 100, a cabinet 200, a charging device 300, and a charging cable 400. The wire take-up device 100 is arranged on the top of the cabinet 200. One end of the charging cable 400 is connected to the cabinet 200, and the other end is connected to the charging device 300. When not in use, the charging device 300 is plugged into the charging seat 210 of the cabinet 200.

[0041] In one embodiment, if Figure 1As shown, the fixed base 1 is arranged on the top of the cabinet 200. By arranging the fixed base 1 on the top of the cabinet 200, on the one hand, the cabinet 200 can support the fixed base 1, and there is no need to install additional support columns to support the fixed base 1, which has a compact structure, saves materials, and has good economy. On the other hand, the top area of ​​the fixed base 1 can be larger than the top area of ​​the cabinet 200 to shield the charging pile, and to a certain extent prevent objects from falling from the top of the cabinet 200 and causing accidental damage to the charging pile.

[0042] The above charging piles provide electric energy charging services for electric vehicles. By connecting the charging interface of the electric vehicle and the charging pile, electric energy can be transmitted from the power grid to the battery system of the electric vehicle for charging. The charging pile can provide different power and different types of charging modes to meet the charging needs of different electric vehicles.

[0043] like Figure 2 As shown, the wire take-up device 100 includes a fixed base 1, a swing arm 2, a reset assembly 3 and a suspension member 4.

[0044] In some embodiments, Figure 2 or Figure 3 As shown, the fixed base 1 includes a top 11, a bottom 12 and a plurality of side walls 13. The plurality of side walls 13 are used to connect the top 11 and the bottom 12, and are arranged between the top 11 and the bottom 12. For example, Figure 2 As shown, the side wall 13 includes a first side wall 131 arranged along the Y direction, and a second side wall 132 arranged along the X direction.

[0045] In some embodiments, Figures 2 to 5 As shown, the swing arm 2 is connected to the connection fixing base 1, and the swing arm 2 has a folded position (refer to Figure 4 ) and the expanded position (refer to Figure 2 or Figure 5 ), the swing arm 2 can move between a folded position and an extended position. The angle between the swing arm 2 in the folded position and the fixed base 1 is smaller than the angle between the swing arm 2 in the extended position and the fixed base 1.

[0046] In some embodiments, Figure 2 or Figure 3As shown, the reset assembly 3 is arranged on the fixed base 1. The reset assembly 3 includes a flexible traction member 32 (which can be called a traction rope), one end of which is connected to the swing arm member 2, and the flexible traction member 32 is configured to make the swing arm member 2 have a tendency to reset from the extended position to the folded position. The swing arm member 2 moves between the folded position and the extended position under the traction of the flexible traction member 32. It can be understood that since the flexible traction member 32 is elastic, when the swing arm member 2 is in the extended position, the flexible traction member 32 will be in a stretched state, and therefore, the flexible traction member 32 will have a traction force on the swing arm member 2 to move the swing arm member 2 toward the folded position.

[0047] In some embodiments, Figure 2 or Figure 3 As shown, the reset assembly 3 includes a reset seat 31, and one end of the flexible traction member 32 is connected to the reset seat 31. The reset seat 31 includes a housing 311 and a rope outlet 312. The rope outlet 312 can be arranged in the housing 311, and the flexible traction member 32 is connected to the swing arm member 2 through the rope outlet 312. Of course, the rope outlet 312 can also be arranged on one side of the housing 311 (such as Figure 2 The rope outlet portion 312 may be a rotating shaft, and the flexible traction member 32 is wound on the rotating shaft. During the movement, the rotating shaft controls the length of the flexible traction member 32 by its own forward or reverse rotation.

[0048] Exemplarily, when the rope output portion 312 rotates forward, the flexible traction member 32 will be output from the reset seat 31, that is, the length of the flexible traction member 32 becomes longer, and the swing arm member 2 rotates and unfolds under the traction of the user. After the charging device 300 is charged and returned, the rope output portion 312 can be reversed to shorten the length of the flexible traction member 32, so that the swing arm member 2 is reset under the traction of the flexible traction member 32.

[0049] In one embodiment, if Figure 2 As shown, there are two rope outlets 312, the rope outlet 312 on the left side protrudes from the left side of the housing 311, and the flexible traction member 32 on the left side extends through the rope outlet 312 on the left side and is connected to the swing arm member 2 on the left side. Similarly, the rope outlet 312 on the right side protrudes from the right side of the housing 311, and the flexible traction member 32 on the right side extends through the rope outlet 312 on the right side and is connected to the first swing arm member 21 on the right side.

[0050] In some embodiments, Figure 2 As shown, the fixed base 1 has an axis K, and the rope outlet portion 312 on the left and the rope outlet portion 312 on the right are symmetrical about the center of the axis K. In this way, the structures of the two reset assemblies 3 arranged on the fixed base 1 can be exactly the same, so that the structure of the wire taking-up device is compact, material is saved, and the economy is good.

[0051] In one embodiment, the reset seat 31 may further include a resetter (not shown), which is disposed in the housing 311 and connected to the rope outlet 312. The resetter may include but is not limited to a spring or a cylinder, etc., and the resetter may drive the swing arm 2 to automatically move to the retracted position.

[0052] In one embodiment, if Figure 3 As shown, the hanging member 4 is arranged on the swing arm member 2, and the hanging member 4 is used to hang the charging cable 400, wherein the hanging member 4 can be connected to the swing arm member 2 through a connecting component such as a rope, so that the charging cable 400 can have a swinging space and the pulling direction of the charging cable 400 can be flexibly controlled.

[0053] Combination Figure 3 As shown, the suspension member 4 is installed below the swing arm member 2 , so that when the charging cable 400 is suspended on the suspension member 4 , the charging cable 400 can be prevented from being worn due to contact with the swing arm member 2 .

[0054] The hanging member 4 is provided with a hanging ring 41, and the charging cable 400 passes through the hole of the hanging ring. The hanging ring 41 can improve the connection reliability between the charging cable hanging member 4 and the charging cable 400, so as to reduce the risk of the charging cable 400 being separated from the hanging member 4.

[0055] The charging cable 400 can be hung on the swing arm 2, such as Figure 3 As shown, a charging cable 400 can be hung on the hanging member 4 below the left swing arm member 2. Similarly, a charging cable 400 can also be hung on the hanging member 4 below the right swing arm member 2.

[0056] In this way, the charging cable 400 will not be under stress all the time, and the swing arm 2 can bear part of the weight of the charging cable 400. Therefore, when the user uses the charging device 300 to charge, the user can control the swing arm 2 to share part of the weight of the charging cable 400, making it easier for the user to handle the charging cable 400, providing a better charging experience for the user.

[0057] In one embodiment, if Figure 2 As shown, the swing arm member 2 includes a first swing arm portion 21 and a second swing arm portion 22 , the first swing arm portion 21 is connected to the second swing arm portion 22 , and the first swing arm portion 21 is movably connected to the fixed base 1 .

[0058] The first swing arm portion 21 and the second swing arm portion 22 may be an integrally formed structure, so that the first swing arm portion 21 can be prevented from shaking when rotating, thereby reducing the shaking amplitude of the charging cable 400 when being pulled.

[0059] In one embodiment, if Figures 2 to 5As shown, the first swing arm portion 21 and the second swing arm portion 22 are arranged at an angle, so that when the swing arm member 2 is folded, the second swing arm portion 22 is far away from the cabinet 200, thereby preventing the charging cable 400 from colliding with the cabinet 200 of the charging pile and causing wear of the charging cable 400.

[0060] Exemplarily, the angle between the first swing arm portion 21 and the second swing arm portion 22 can be an acute angle, an obtuse angle or a right angle, and no special limitation is made here, as long as the collision between the charging cable 400 and the cabinet 200 of the charging pile can be avoided.

[0061] In one embodiment, there are two swing arm members 2 . It can be understood that the first swing arm portion 21 on the left side is movably connected to the left side of the fixed base 1 , and the first swing arm portion 21 on the right side is movably connected to the right side of the fixed base 1 .

[0062] In one embodiment, if Figure 2 or Figure 3 As shown, each swing arm member 2 is connected to two first side walls 13 oppositely arranged on the fixed base 1 through a connecting member 20. It can be understood that the swing arm member 2 on the left is connected to the first side wall 131 on the left side of the fixed base 1 through the connecting member 20, and similarly, the swing arm member 2 on the right is connected to the first side wall 131 on the right side of the fixed base 1 through the connecting member 20.

[0063] In one embodiment, if Figure 2 As shown, each first side wall 131 has a first end 1311 and a second end 1312 in the first direction X, the reset assembly 3 is arranged near the first end 1311, and the swing arm 2 is arranged near the second end 1312, so that the flexible traction member 32 is roughly vertically connected to the swing arm 2 and the reset assembly 3, and when the swing arm 2 is rotated and unfolded under the traction of the charging cable 400, the pulling force directly acts on the swing arm 2, so that the user can pull more effortlessly. It can be understood that if the swing arm 2 and the reset assembly 3 are located at the same end, when the swing arm 2 is in a retracted state, the flexible traction member 32 is obliquely connected to the swing arm 2 and the reset assembly 3, so that when the swing arm 2 is rotated and unfolded under the traction of the charging cable 400, the internal pulling force needs to be converted into a force perpendicular to the swing arm 2, which will increase the force required for the swing arm 2, making it more laborious for the user to pull.

[0064] In one embodiment, if Figure 5As shown, the connecting member 20 includes a first connecting portion 201, a second connecting portion 202 and a pivot pin 203. The first connecting portion 201 is disposed on the first side wall 131. The second connecting portion 202 is disposed on the first swing arm portion 21; the pivot pin 203 is pivotally connected to the first connecting portion 201 and the second connecting portion 202. It can be understood that the first connecting portion 201 is fixed to the left first side wall 131 or the right first side wall 131 by bolts. The second connecting portion 202 is fixed to the first swing arm portion 21 by bolts.

[0065] The connecting member 20 may include but is not limited to a hinge. Each first swing arm portion 21 is connected to the first side wall 13 of the fixed base 1 through its own connecting member 20, so that the swing arm 2 can have a translation effect while rotating.

[0066] The above-mentioned fixed base 1 and swing arm 2 can be made by sheet metal processing. Sheet metal processing refers to cutting, bending, punching, drilling, welding and other process operations on metal plates to obtain the shape and size of the fixed base 1 or the swing arm 2.

[0067] In one embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, when the swing arm 2 is in the retracted position, the swing arm 2 abuts against the first side wall 131, so as to prevent the swing arm 2 from continuing to move in the original direction. Specifically, when the swing arm 2 on the left is in the retracted position, the swing arm 2 on the left abuts against the first side wall 131 on the left. Similarly, when the swing arm 2 on the right is in the retracted position, the swing arm 2 on the right abuts against the first side wall 131 on the right.

[0068] In one embodiment, the maximum movable angle of the swing arm 2 is relative to the structure of the fixed base 1. For example, the structure of the fixed base 1 provided in the embodiment of the present application is rectangular, so the maximum movable angle of the swing arm 2 is 270°, so that the swing space of the charging cable 400 can be increased, and more choices can be provided for users of charging cars parked in various directions, thereby improving the user experience.

[0069] In one embodiment, if Figure 2 or Figure 3 or Figure 4 or Figure 5 As shown, the wire take-up device 100 further includes a connecting column 5, and the flexible traction member 32 is connected to the swing arm member 2 via the connecting column 5. Specifically, one end of the flexible traction member 32 on the left side extends from the rope outlet portion 312 on the left side, and the other end is fixed to the connecting column 5 of the swing arm member 2 on the left side. Similarly, one end of the flexible traction member 32 on the right side extends from the rope outlet portion 312 on the right side, and the other end is fixed to the connecting column 5 of the swing arm member 2 on the right side. The flexible traction member 32 can be fixed to the connecting column 5 by tying a knot, but is not limited thereto.

[0070] Combination Figure 1 As shown, when using the charging pile, the user removes the charging device 300 from the socket of the cabinet 200. When the charging device 300 is pulled to the car charging port, the charging cable 400 pulls the swing arm 2 to rotate from the folded position to the unfolded position. Figure 3 and Figure 5 The diagram shows the swing arm 2 unfolded to a 90° position. The movable angle of the swing arm 2 depends on the position of the car charging port. If the car charging port is relatively close to the charging device 300, the movable angle of the swing arm 2 is relatively small. On the contrary, if the car charging port is relatively far from the charging device 300, the movable angle of the swing arm 2 is relatively large. After the car charging is completed, the user returns the charging device 300 to the charging seat 210 of the cabinet 200, and the flexible traction member 32 output by the reset component 3 drives the swing arm 2 to rotate and reset. Since the charging cable 400 is suspended on the swing arm 2, the swing arm 2 can bear part of the weight of the charging cable 400, so that the user does not have to bear the entire weight of the charging cable 400 when pulling the charging cable 400, making it easier for the user to pull the charging cable 400, thereby providing the user with a better charging experience.

[0071] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0072] The above is a detailed introduction to a wire-retracting device and a charging pile provided in the embodiments of the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the technical solution and its core idea of ​​the present application. Ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
