Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of charging pile auxiliary equipment especially relates to a line bundle movable clamping equipment of electric automobile charging pile. BACKGROUND

[0002] With the popularity of new energy vehicles, charging piles as a device for providing charging services for electric vehicles are also increasing, which realize the battery charging function by transmitting the power of the power grid to the battery of the electric vehicle. Based on the consideration of charging efficiency, the charging wire connected to the automobile charging port on the charging pile is often larger in diameter. After the charging gun is inserted into the automobile charging port, the connecting wire is in a free stress state. Due to the large gravity of the charging wire, a certain degree of tension is generated at both ends of the connecting wire, which leads to unstable connection between the charging gun and the automobile charging port.

[0003] The prior art discloses a utility model patent, named: charging pile wire harness limiting device, the publication number is: CN221023300U. It includes a charging groove, a support limiting rod bottom plate is connected outside the middle part of the bottom of the pile groove through a swing bolt, a group of support limiting rods with adjustable angles are slidably connected on the support limiting rod bottom plate, an arc-shaped support block is rotatably connected at the top end of the support limiting rod, and the arc-shaped support block is used for supporting the connecting wire.

[0004] But the support limiting rod in the patent application specification has no direct connection with the charging wire. In the actual use process, the charging wire needs to be manually placed on the support limiting rod. However, the user often does not operate in this way. In addition, it is also a problem whether the support limiting rod can provide sufficient support to the charging wire, because the length of the charging wire pulled by the user is not constrained. When the user pulls out a long charging wire, even if the charging wire is placed on the support limiting rod, it cannot effectively reduce the problem of unstable connection between the charging gun and the automobile charging port. UTILITY MODEL CONTENTS

[0005] The utility model aims at solving the problem that the support limiting rod in the prior art cannot effectively limit the charging wire, so as to improve the influence of the charging wire on the stability of the automobile charging port.

[0006] In order to achieve the above object, the application provides a wire harness movable clamping device of an electric vehicle charging pile, which comprises a charging pile, a charging wire arranged on the charging pile, a charging head connected to the end of the charging wire, a guide rail base arranged on the front of the charging pile, a sliding block mounted on the guide rail base, a supporting rod hingedly connected to the sliding block and disposed on the guide rail base, a locking device arranged on the end of the supporting rod away from the guide rail base, a mounting seat arranged on the front end of the charging pile, the mounting seat being provided with a first telescopic rod hingedly connected thereto, wherein the other end of the first telescopic rod is connected to the input end of the locking device, the charging wire passes through the clamping part of the locking device, and the charging head is arranged on the side of the locking device away from the charging pile.

[0007] The wire harness movable clamping device of the electric vehicle charging pile of the application realizes the fixation of the charging wire by arranging the locking device on the top end of the supporting rod, and realizes the fixation of the charging wire by arranging the first telescopic rod connected to the locking device on the charging pile, so that the first telescopic rod provides a pulling force to the locking device during the change of the angle between the supporting rod and the guide rail base, and the pulling force is transmitted to the locking device, so that the cavity of the locking device gradually shrinks, the locking device completely covers the charging wire after the first telescopic rod reaches the maximum extension stroke, and finally the clamping of the charging wire is completed, thereby solving the problem that the supporting limiting rod in the prior art cannot effectively limit the charging wire and the problem that the charging wire affects the stability of the charging port of the vehicle.

[0008] As an improvement of the above-mentioned locking device, in order to convert the pulling force of the first telescopic rod to the locking device into the clamping force of the locking device to the charging wire, the locking device comprises a first clamping part connected to the end of the supporting rod, a second clamping part symmetrically arranged with the first clamping part, first pin columns arranged on the same side wall of the first clamping part and the second clamping part and staggered, a V-shaped connecting rod with one end connected to the first pin column on the first clamping part, the middle connected to the second pin column on the second clamping part, and the other end connected to the movable rod, wherein the end of the movable rod close to the charging pile is hingedly connected to the end of the first telescopic rod.

[0009] Further, in order to make the locking device have a better clamping effect on the charging wire, that is, to make the locking device have a larger contact area with the charging wire, two end faces of the first clamping part and the second clamping part are provided with grooves.

[0010] Further, in order to improve the stability of the locking device, the movable rod is at least two, and is arranged in parallel on the side wall of the first clamping part and the second clamping part.

[0011] Further, in order to make the support rod not contact with the guide rail base when not in use, so as to ensure that the locking device does not contact with the guide rail base and is not damaged, the top of the second clamping part is provided with a first buckle, and a second buckle matched with the first buckle is arranged on the front face of the charging pile, wherein the plane determined by the first buckle and the second buckle is parallel to the guide rail of the guide rail base.

[0012] Further, in order to limit the maximum angle between the support rod and the guide rail base, a limiting baffle perpendicular to the guide rail base is arranged on the side of the sliding block away from the charging pile.

[0013] Further, in order to make the wire harness movable clamping device be able to preset different maximum stretching lengths of the charging wire by changing the angle of the movable rod when the sliding block is in different positions in the guide rail base, the support rod comprises a hollow rod hinged to the sliding block and a telescopic rod arranged on the hollow rod.

[0014] The application has the following beneficial effects:

[0015] 1. The wire harness movable clamping device of the electric vehicle charging pile of the application realizes the fixation of the charging wire by arranging the locking device at the top end of the support rod, and at the same time, the first telescopic rod connected with the locking device is arranged on the charging pile, so that the first telescopic rod provides a pulling force to the locking device during the change of the angle between the support rod and the guide rail base, and the pulling force is transmitted to the movable rod through the V-shaped connecting rod, the distance between the first clamping part and the second clamping part is gradually reduced through the change of the angle of the movable rod, and finally the clamping of the charging wire is completed, so that the charging wire cannot be stretched after reaching the preset length, and the problem that the support limiting rod of the prior art cannot effectively limit the charging wire and affects the stability of the charging port of the vehicle is solved.

[0016] 2. The charging wire of the application is preliminarily fixed by passing through the locking device when the charging pile is not in use, and the user only needs to hold the charging head when charging to drive the locking device, so that the support rod rotates around the sliding block as the fulcrum, and the locking of the charging wire by the locking device is realized through the stretching of the first telescopic rod, without the need for the user to actively open the support rod and place the charging wire on the support rod, which is convenient to operate and can achieve the expected clamping without considering human interference factors.

[0017] 3. The first buckle and the second buckle are arranged at the end of the locking device and the front face of the charging pile, so that the movable clamping device does not contact with other components when not working, thereby avoiding the damage caused by the contact between the locking device and other components.

[0018] 4. The support rod of this application is composed of a hollow rod and a telescopic rod nested together, so that the support rod has a telescopic range. Since the farthest distance between the slider and the charging pile on the guide rail base is determined by the sum of the length of the support rod and the maximum extension of the first telescopic rod, the telescopic range of the support rod allows for a larger adjustment range in the position of the slider on the guide rail base. This, in turn, allows for a larger adjustment range in the extension distance of the charging cable when it is not clamped by the locking device, thereby increasing the application scenarios of the wiring harness clamping device for electric vehicle charging piles and enabling it to charge larger vehicles.

[0034] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings. Figures 1 to 3 The embodiments of the technical solutions of the present application will be described in detail. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0035] Embodiment one:

[0036] As Figures 1 to 3 The wire harness movable clamping device of the electric vehicle charging pile of the present application is illustrated, in this embodiment, in order to achieve effective fixation of the charging wire, the wire harness movable clamping device of the electric vehicle charging pile of the present application is provided with a locking device 7 at the top end of the support rod 6 to achieve fixation of the charging wire 2.

[0037] Specifically, when the charging wire 2 passes through the clamping part of the locking device 7 and the charging head 3 is placed on the side of the locking device 7 away from the charging pile 1, the clamping part of the locking device 7 can preliminarily fix the charging wire 2. Since the charging wire is naturally stressed, the lower surface of the charging wire 2 will be embedded in the groove of the first clamping part 71, thereby completing the preliminary fixation of the charging wire 2.

[0038] Alternatively, the preliminary fixation of the charging wire 2 to the first clamping part 71 is achieved by the friction force between the charging wire 2 embedded in the groove and the first clamping part 71, or a corresponding buckle is provided in the groove to achieve the preliminary fixation of the charging wire 2. Since the buckle is prior art, it will not be described here.

[0039] Further, the user pulls out the charging head 3 on the charging pile 1, and as the charging head 3 gradually moves towards the car charging port, the charging wire 2 preliminarily fixed with the locking device 7 will drive the support rod 6, so that the angle between the support rod 6 and the guide rail base 4 changes. At this time, the first extension rod 9 is gradually stretched, thereby generating a pulling force on the locking device 7 towards the charging pile 1. This pulling force is transmitted to the movable rod 75 through the V-shaped connecting rod 76, and the angle change of the movable rod 75 gradually reduces the distance between the first clamping part 71 and the second clamping part 72, thereby finally achieving clamping of the charging wire 2. This design ensures that the charging wire 2 cannot be lengthened after reaching the preset length, thereby improving the connection stability between the charging wire 2 and the car charging port.

[0040] Embodiment two:

[0041] As Figures 1 to 3The application discloses a kind of electric vehicle charging pile's wire harness movable clamping equipment, in this embodiment, to realize convenient operation and without considering human interference factor, when charging pile 1 is not used, charging wire 2 has been preliminarily fixed by locking device 7.When user needs to charge, just pick up charging head 3, it can drive locking device 7 and support rod 6 to rotate with sliding block 5 as fulcrum. With the rotation of support rod 6, first telescopic rod 9 gradually stretches, and realizes the locking of charging wire 2 by the mechanical structure in locking device 7. This design does not need user to actively open support rod 6 and place charging wire 2 on support rod 6, operation is more convenient. At the same time, since the whole locking process is automatically completed by mechanical structure, human interference factor does not need to be considered, and the expected clamping effect can be ensured.

[0042] Embodiment three:

[0043] As Figures 1 to 3 The application discloses a kind of electric vehicle charging pile's wire harness movable clamping equipment, in this embodiment, to avoid damage caused by locking device and other components contact, first buckle 77 and second buckle 78 are provided at the end of locking device 7 and the front of charging pile 1.

[0044] Specifically, when movable clamping device does not work, first buckle 77 on second clamping part 72 and second buckle 78 on charging pile 1 can be mutually buckled, so that locking device 7 is kept in a fixed position, avoid contact with other components. This design can effectively prevent damage of locking device 7 caused by contact with other components, prolong the service life of equipment.

[0045] Embodiment four:

[0046] As Figures 1 to 3 The application discloses a kind of electric vehicle charging pile's wire harness movable clamping equipment, in this embodiment, to increase the adaptability of application scene, support rod 6 is made of hollow rod 61 and telescopic rod 62 nesting, so that support rod 6 has telescopic amount. Since the farthest distance of sliding block 5 on guide rail base 4 from charging pile 1 is determined by the sum of the length of support rod 6 and the maximum elongation of first telescopic rod 9, so that support rod 6 has telescopic amount can make the preset position of sliding block 5 on guide rail base 4 have greater adjustment range.

[0047] Specifically, in the initial installation of the movable clamping device of the electric vehicle charging pile, the distance between the commonly used automobile charging port and the charging pile 1 can be determined to determine the length of the charging wire 2 that needs to be extended. According to this length, the installation position of the sliding block 5 on the guide rail base 4 is determined according to the principle that the length of the charging wire 2 that needs to be extended is greater than the distance from the sliding block 5 to the charging pile, and the limiting baffle 10 is installed. Then, according to this distance, the support rod 6 and the first telescopic rod 9 with appropriate length are selected, so that the distance from the sliding block 5 on the guide rail base 4 to the charging pile 1 is equal to the sum of the length of the support rod 6 and the maximum extension amount of the first telescopic rod 9. Thus, the preliminary setting of the extension length of the charging wire is completed, which means that the extension distance of the charging wire 2 when it is not clamped by the locking device 7 can have a larger adjustment range, thereby increasing the application scenarios of the movable clamping device of the electric vehicle charging pile. For example, the device can be applied to larger vehicles for charging, thereby improving the versatility and practicality of the device.
