Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, in particular to a swing arm type cable management system and a charging pile. Background Art

[0002] The cable management system provided in the charging pile can release or recycle the cable of the charging gun when pulling the cable of the charging gun. Currently, the commonly used cable management systems are mechanical spring type, spring type, counterweight type, and swing arm type.

[0003] For traditional mechanical spring type and spring type cable management systems, when users use them, they need to overcome the self - gravity of the cable and the reverse reset elastic force of the spring (or spring). The longer the distance of pulling the cable, the greater the reverse reset elastic force of the spring (or spring), and the worse the user experience. In addition, the elastic force of the spring (or spring) will gradually decay, resulting in the failure of cable management.

[0004] For traditional mechanical counterweight type cable management systems, the internal counterweight is a solid metal with a large weight. When users use them, they need to overcome the self - gravity of the counterweight. The longer the distance of pulling the cable, the larger the angle with the horizontal direction, and the greater the pulling force, and the worse the user experience.

[0005] For traditional mechanical swing arm type cable management systems, limited by the inherent length of the swing arm, the extension range of the cable is small, and the effective charging distance is insufficient. In addition, the mechanical swing arm type cable management system needs to set an elastic structure or a door closer between multiple hinged swing arms for the reset of the swing arm, but at the same time, it also increases the horizontal resistance when the user pulls the cable, affecting the user experience, and there is also a problem that the cable management is prone to failure. Summary of the Utility Model

[0006] The utility model provides a swing arm type cable management system and a charging pile to solve the above - mentioned technical problems, which can increase the effective charging distance of the cable, reduce the operation pulling force requirement in the horizontal direction, improve the user experience, and is not easy to fail, with high reliability.

[0019] Furthermore, the electric drive unit further includes a torque sensor and a drive controller, wherein the torque sensor is used to detect the torsional torque of the motor, and the drive controller is used to control the rotation of the motor when the torque sensor detects the torsional torque.

[0020] In addition, to achieve the above-mentioned purpose, the utility model also proposes a charging pile.

[0021] A charging pile comprises: a charging pile body and the swing-arm type gun line management system as described above, wherein the swing-arm type gun line management system is mounted on the charging pile body, and a gun line cable of the charging gun is connected to the rope.

[0022] Beneficial effects of the utility model:

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figure 1 shown, the swing arm type gun line management system of the embodiment of the present invention is used to manage the gun line cable and includes: a rope 1, a mechanical coupling unit 2, and an electric drive unit 3. Among them, the first end of the rope 1 is fixedly connected to a preset position of the gun line cable; the mechanical coupling unit 2 includes a base 21, a swing arm assembly 22, and a first blocking mechanism 23. The fixed end of the swing arm assembly 22 is fixed on the base 21, and the swing arm assembly 22 is movable between a retracted position and an extended position; the first blocking mechanism 23 is fixedly arranged at the free end of the swing arm assembly 22. After the first end of the rope 1 passes through the first blocking mechanism 23, it is connected to the preset position of the gun line cable; the electric drive unit 3 is connected to the second end of the rope 1, and the electric drive unit 3 is used to control the release or recovery of the rope 1. Among them, the rope 1 can be a steel wire rope, a nylon rope, a PE rope, or a rope made of other materials; the rope 1 can be connected to the preset position of the gun line cable by means of a rope buckle, a fixture, a rope knot method, or other fixed connection methods; the preset position of the gun line cable can be a position in the middle of the gun line cable set according to actual needs; the fixed end of the swing arm assembly 22 can be fixed on the base 21 by means of hinge connection, pin connection, etc., and this embodiment does not limit it.

[0035] As Figure 2 and Figure 3 shown, when the electric drive unit 3 controls the rope 1 to be recovered, the gun line cable abuts against the first blocking mechanism 23, so that the force for recovering the rope 1 provided by the electric drive unit 3 drives the swing arm assembly 22 to move towards the retracted position; when the electric drive unit 3 controls the rope 1 to be released, the force for releasing the rope 1 and the gun line cable out of the system drives the swing arm assembly 22 to extend towards the extended position, so as to increase the effective charging distance of the gun line cable.

[0036] It can be understood that by setting the rope 1 that can be recycled and released, compared with the traditional mechanical swing arm type gun line management system, the effective charging distance of the gun line cable can be increased to meet the demand for long-distance charging; when the electric drive unit 3 controls the rope 1 to be recycled, the gun line cable abuts against the first blocking mechanism 23, which can make the rope 1 drive the swing arm assembly 22 to move towards the retracted position. There is no need to set an elastic structure or a door closer on the swing arm assembly 22 for resetting, so that the operating pulling force requirement in the horizontal direction when the user operates the gun line cable or the charging gun can be reduced, the user experience can be improved, and it is not easy to fail and has high reliability.

[0037] As Figure 1 shown, in an embodiment of the present invention, a hoop 11 may be provided at the first end of the rope 1, and the gun line cable is connected to the rope 1 through the hoop 11. When the electric drive unit 3 controls the rope 1 to be recycled, the hoop 11 abuts against the first blocking mechanism 23, so that the rope 1 drives the swing arm assembly 22 to move towards the retracted position. It can be understood that the hoop 11 can be an elastic hoop, and the size of the elastic hoop matches the diameter of the gun line cable. The hoop 11 can also be a set of buckles, and the diameter of the through hole between the buckles matches the diameter of the gun line cable, etc. This embodiment is not limited.

[0038] As Figure 1 shown, in an embodiment of the present invention, the swing arm assembly 22 includes at least two connecting rods 221, and a joint shaft 222 is provided between every two adjacent connecting rods 221, so that the connecting rods 221 rotate through the joint shaft 222. In some other embodiments of the present invention, other rotational connection methods such as pin connection can also be used to connect two adjacent connecting rods 221. This embodiment is not limited.

[0039] As Figure 4 shown, in an embodiment of the present invention, a first fixed pulley assembly 24 is provided on the connecting rod 221, or a first fixed pulley assembly 24 is provided between the swing arm assembly 22 and the electric drive unit 3. The second end of the rope 1 bypasses the first fixed pulley assembly 24 and is connected to the electric drive unit 3. Optionally, a plurality of first fixed pulley assemblies 24 can also be respectively provided between the connecting rod 221, the swing arm assembly 22 and the electric drive unit 3, so that after the rope 1 extends from the electric drive unit 3, it passes through one or more first fixed pulley assemblies 24 and is connected to the gun line cable through the first blocking mechanism 23, and the traveling path of the rope 1 between the electric drive unit 3 and the free end of the swing arm assembly 22 is set as a preset path. Among them, the preset path can be a path that is easy for the rope 1 to pass smoothly according to the actual structure of the system.

[0040] As Figure 5 and Figure 6As shown, in a specific embodiment of the present utility model, the first fixed pulley assembly 24 may include a plurality of first fixed pulleys 241 and a first fixing plate 242. Among them, both ends of the fixed shaft of the first fixed pulley 241 are fixed on the first fixing plate 24. A channel suitable for the rope 1 to pass through is left between the plurality of first fixed pulleys 241, so that the rope 1 can pass through the channel between the plurality of first fixed pulleys 241, and then be connected to the gun line cable through the first blocking mechanism 23. It can be understood that other rope guiding mechanisms or structures can also be adopted, such as opening a guiding groove on the connecting rod 221 that is easy for the rope 1 to pass through, etc., to ensure that the rope 1 moves smoothly and orderly on the preset path. This embodiment is not limited thereto.

[0041] As Figure 7 shown, in an embodiment of the present utility model, the first blocking mechanism 23 may include a blocking plate 231 fixedly arranged at the free end. A gap suitable for the rope 1 to pass through is provided on the blocking plate 231, so that the rope 1 can pass through the blocking plate 231, while other devices connected to the rope 1, such as the hoop 1 and the gun line cable, cannot pass through the blocking plate 231. When the electric drive unit 3 controls the rope 1 to retract, other devices connected to the rope 1 abut against the first blocking mechanism 23, so that the force for retracting the rope 1 provided by the electric drive unit 3 can drive the swing arm assembly 22 to move towards the retracted position.

[0042] As Figure 7 shown, in an embodiment of the present utility model, the first blocking mechanism 23 may further include a second fixed pulley assembly 232. The second fixed pulley assembly 232 may include a second fixed pulley and a second fixing plate. The fixed shaft of the second fixed pulley is fixedly arranged on the second fixing plate. The second fixed pulley assembly 232 can be arranged in the same direction as the gap of the blocking plate 231, so that the rope 1 can pass through the gap of the blocking plate 231 vertically, reducing the loss when the rope is retracted and released.

[0043] As Figure 7 shown, the first blocking mechanism 23 may further include a guiding plate 233. Two or more third fixed pulleys are arranged in the guiding plate 233 to provide a low-friction and easy-to-pass channel for the rope 1. The guiding plate 233 can be arranged on the path of the rope 1 from the electric drive unit 3 into the first blocking mechanism 23 to avoid the rope 1 directly rubbing against the swing arm assembly 22, causing wear and affecting the normal use of the swing arm type gun line management system.

[0044] Among them, the second fixed pulley assembly 232 and the guiding plate 233 can exist in combination. This embodiment is not limited thereto.

[0045] In an embodiment of the present utility model, a second blocking mechanism is provided between every two adjacent link rods 221, and the second blocking mechanism is used to block the collision between two adjacent link rods 221. In some other embodiments of the present utility model, a third blocking mechanism may also be provided on the side edge of the base 21 of the fixed swing arm assembly 22 to block the collision between the link rod 221 and the base 21.

[0046] Based on the above structure, the working principle of the swing arm type gun line management system in this embodiment is as follows: As Figure 8 shown, point A represents a point on the side edge AB of the fixed end of the base 21 for fixing the swing arm assembly 22, where the swing arm assembly 22 includes a link rod BD and a link rod CD; point B represents the position of the fixed end of the swing arm assembly 22 fixed on the side edge AB; point C represents the connection point of the link rod BC and the link rod CD, and at the same time is the position where the joint axis between the two link rods is located; point D represents the free end of the link rod CD, that is, the free end of the swing arm assembly 22; point G1 represents the position of the blocking point of the third blocking mechanism; point G2 represents the position of the blocking point of the second blocking mechanism provided on the link rod BC; the dotted line LD represents the preset path of the rope 1; point M represents the position of the rope guiding mechanism provided on the link rod BD.

[0047] Among them, the link rod BC and the side edge AB of the base 21 form a rotational pair with point B as the rotation axis, and the link rod CD and the link rod BC form a rotational pair with point C as the rotation axis. The first end of the rope 1 is connected to the gun line cable through point D, the rope 1 passes through point M and point L through the first blocking mechanism 23 respectively, and the second end of the rope 1 is connected to the electric drive unit 3.

[0048] When the electric drive unit 3 controls the rope 1 to retract, the electric drive unit 3 pulls the rope 1. The first end of the rope 1 is fixed at point D through the first blocking mechanism 23 and the gun line cable, realizing the driving force in the F direction, so that BC and CD rotate, forming a two-degree-of-freedom double-stage link mechanism. When the link rod BC reaches the blocking point G1, it stops, and when the link rod CD reaches the blocking point G2, it stops.

[0049] As Figure 4 and Figure 9 shown, in an embodiment of the present utility model, the electric drive unit 3 includes a motor 31 and a wire reel 32 provided on the motor 31. The motor 31 is used to drive the wire reel 32 to rotate, and the second end of the rope 1 is wound around the wire reel 32, so that when the wire reel 32 rotates, it drives the rope 1 to be released or retracted. It can be understood that the motor 31 in this embodiment can be a servo motor, a stepper motor or other types of motors, and this embodiment does not impose any restrictions.

[0050] In one embodiment of the present utility model, the electric drive unit 3 further includes a torque sensor and a drive controller. The torque sensor is used to detect the torsional moment of the motor 31, and the drive controller is used to control the rotation of the motor 31 when the torque sensor detects the torsional moment.

[0051] In one embodiment of the present utility model, the torque sensor can automatically convert the detected current and voltage of the motor 31 into torque values, and the drive controller can convert the torque values into electrical signals to drive the motor 31 to rotate. The motor 31 can drive the wire reel 32 to rotate synchronously. Each time the motor 31 receives an electrical signal, it can control the wire reel 32 to rotate one circle, releasing a small section of the rope 1 to increase the movable range of the gun line cable and achieve a macro defense line.

[0052] After the charging is completed, the drive controller receives the signal of the charging completion and the charging gun being unplugged, and controls the motor 31 to rotate in the reverse direction. The wire reel 32 rotates synchronously in the reverse direction to recover the rope 1. At this time, the rope 1 drives the swing arm assembly 22 to move towards the retracted position through the rope guiding mechanism on the connecting rod 221 until it is reset to the retracted position. The rope 1 and the hoop 11 are also reset to the initial state synchronously, realizing the function of automatically recovering the gun line.

[0053] Based on the swing arm type gun line management system of the above embodiment, the present utility model also proposes a charging pile.

[0054] As Figure 2 and Figure 3 shown, the charging pile of the embodiment of the present utility model includes a charging pile body and the swing arm type gun line management system of any one of the above embodiments of the present utility model. Among them, the swing arm type gun line management system is assembled on the charging pile body, and the gun line cable of the charging gun is connected to the rope 1.

[0055] As Figure 2 and Figure 3 shown, in one embodiment of the present utility model, the base 21 of the swing arm type gun line management system can be assembled on the top of the charging pile body. When the swing arm assembly 22 is in the retracted position, the position where the rope 1 is connected to the gun line cable is close to the first blocking mechanism 23, so that when the user pulls the gun line cable, only a small part of the gravity of the gun line cable needs to be overcome in the vertical direction, effectively reducing the operation pulling force requirement in the vertical direction and improving the user experience.

[0056] According to the charging pile of the embodiment of the present utility model, since it includes the above swing arm type gun line management system, it can increase the effective charging distance of the gun line cable, reduce the operation pulling force requirement in the horizontal direction, improve the user experience, and is not easy to fail, with high reliability.

[0057] In the description of the present utility model, "a plurality of" means two or more, unless otherwise specifically defined.

[0058] In the present utility model, unless otherwise clearly specified or defined, terms such as "installed", "connected", "joined", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components.

[0059] In the present utility model, unless otherwise clearly specified or defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.
