Description

Technical Field

[0001] The invention belongs to the technical field of charging pile testing equipment, and specifically discloses a super charging pile testing device. Background Art

[0002] With the development of the national economy and the increase in residents' income, the demand for energy is also increasing. However, cars using oil are one of the culprits of urban air pollution and an important factor in global warming. In order to save energy and reduce emissions and protect the atmospheric environment, the use of clean energy has become an inevitable trend. Electric vehicles powered by electricity can reduce urban air pollution and improve urban air quality. Therefore, they are widely advocated by people and require corresponding supporting facilities to be improved. For example, how to charge electric vehicles conveniently, AC charging piles have appeared accordingly, but AC charging piles need to be tested during installation. Most of the existing testing devices are large in size and cannot be moved very conveniently, and the plugs cannot be plugged in and out quickly during testing.

[0003] During the test of super charging piles, the test device needs to be moved to the designated position for testing. If multiple charging piles are tested, the number of moves will increase. During the movement, the test cables need to be arranged in advance by the operator, otherwise the cables will be worn due to dragging on the ground, and the movement speed of the test device will be slowed down. If there is water accumulation or conductive structure on the ground, it is easy to cause damage to the test device, affecting the service life of the test device. When a test is completed, the wires that have just been tested need to be unplugged and inserted into another set of charging piles. If the cables are arranged every time, the test difficulty of the operator is greatly increased, affecting the test efficiency.

[0004] How to avoid entanglement of multiple test harnesses, reduce damage caused by harness pulling, and achieve rapid wire retraction and placement of measurement plugs is a problem that technical personnel in this field need to solve. Summary of the invention

[0005] In order to solve the problems in the background technology, the present invention provides a super charging pile testing device, and the specific technical solution is as follows:

[0006] A super charging pile testing device comprises a testing mechanism and a control structure installed on the testing mechanism, wherein the testing mechanism comprises an outer shell, a first handle is fixed on the top of the outer shell, and a universal wheel is arranged on the bottom of the outer shell;

[0007] A mounting mechanism which is box-shaped and has a built-in testing mechanism is installed on one side of the testing mechanism. The mounting mechanism is embedded in the outer shell and the bottom is hinged to the outer shell through a horizontal axis. A foldable supporting mechanism is also installed on the outside of the mounting mechanism. When the mounting mechanism is embedded, the supporting mechanism is folded and fits the outer surface of the mounting mechanism. When the mounting mechanism is opened, the supporting mechanism unfolds and abuts the ground, limiting the opening angle of the mounting mechanism.

[0008] Preferably, the facade of the outer shell that is not blocked by the mounting mechanism is provided with heat dissipation holes and a liquid cooling oil observation window, and the mounting mechanism is embedded in one side of the outer shell, which means that: a first avoidance groove in the vertical direction is provided on one side of the facade of the outer shell, and a second avoidance groove in the horizontal direction, which is connected to the first avoidance groove, is provided on the top surface of the outer shell, and the L-shaped space formed by the two avoidance grooves is adapted to the outer contour of the mounting mechanism.

[0009] Preferably, a charging gun interface is installed on the inner facade of the second avoidance groove, and a avoidance hole is opened at the lower end of the first avoidance groove, which is connected with the inner cavity of the outer shell as a passage for the test cable.

[0010] Preferably, the installation mechanism embedded in the outer shell is provided with a second handle at the corner of the L-shaped space for opening and closing the installation mechanism, and a plurality of first sliding grooves are provided inside the installation mechanism from top to bottom, which are evenly distributed and parallel to the horizontal axis, and a limiting lock block is fixedly installed on the inner wall for limiting the recovery angle of the installation mechanism.

[0011] Preferably, the test mechanism comprises a test gun head connecting cable led out from the test mechanism through the avoidance hole and a test gun head body fixedly installed at one end of the test gun head connecting cable.

[0012] Preferably, the support mechanism includes a first connecting rod, a second connecting rod, and a third connecting rod hinged in sequence, one side of the first connecting rod is in contact with the outer side of the mounting mechanism, and the other side opposite is provided with a second slide groove along the rod axis direction, and the second slide groove is used to accommodate the second connecting rod and the third connecting rod after folding.

[0013] Preferably, an arranging mechanism is installed inside the installation mechanism, and the arranging mechanism includes a sliding block slidably installed in the first slide groove and a rotating buckle installed on the sliding block through a rotating shaft perpendicular to the bottom of the first slide groove. A set of arranging mechanisms is installed inside each first slide groove, and the sliding blocks in each set of arranging mechanisms are fixed to the groove ends alternately left and right according to the groove sequence through the first elastic member. The test gun head connecting cable passes through each rotating buckle in turn, and the elastic coefficient of the first elastic member along the way gradually decreases from the avoidance hole to the combined end with the test gun head body.

[0014] Preferably, the rotating buckle is provided with an opening for inserting the gun head connecting cable in accordance with the groove sequence.

[0015] Preferably, when the outer shell is embedded in the installation mechanism, a row of limit blocks with openings facing outward and arranged continuously are provided at a position opposite to each first slide groove, which are used to clamp various test harnesses; the openings of each row of limit blocks are the same size, and the distance from the opening to the outer shell decreases successively from the center to the two ends.

[0016] Preferably, the opening is closed by a second elastic member.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] When the device is moved, the cables used for connection are accommodated in the L-shaped space formed by the two avoidance grooves and will not be dragged on the ground, thereby reducing the wear and tear of the cables. After the installation mechanism is unfolded, the opening faces upward, which is convenient for taking the cables. The supporting mechanism effectively ensures the load-bearing capacity of the installation mechanism and limits the movement of the universal wheels, thereby ensuring the stability of the device when in use.

[0019] The connecting cable is clamped in the installation buckle through the installation port. After the installation, the connecting cable is distributed in a snake shape on the side wall of the first embedded plate, which is organized in an orderly manner and occupies a small area, which is convenient for accommodating longer connecting cables. When the connecting cable needs to be extended for use, one end of the connecting cable is pulled until the connecting cable is close to a straight line. After the connecting cable is relaxed, the multiple first elastic members are reset to automatically store the connecting cables, reducing the work of the operator to organize.

[0020] The elasticity of the multiple first elastic parts is different, and their elasticity gradually increases or decreases. When stretched, the end with greater elasticity (smaller elastic coefficient) is stretched first, and when contracted, the end with less elasticity (larger elastic coefficient) is contracted first. This not only facilitates the fixation of one end of the connecting cable, but also increases the flexibility of resetting the connecting cable.

[0021] When some rotating buckles fail to reset successfully, since the openings of each row of limit blocks are the same size and the distance from the openings to the outer shell decreases from the center to both ends, when the installation mechanism is embedded, the protruding limit blocks in the middle will squeeze the rotating buckle to both sides to help the rotating buckle to reset. The rotating buckle will drive the connecting cable to automatically roll to the end point of the first slide groove until all constrained parts of the connecting cable are reset, further enhancing the organizing effect of the device on the connecting cable.

[0022] A plurality of limit blocks are provided, and other test cables can be connected in the limit blocks according to the required path. After the connection is completed, the second elastic member is reset to lock and limit the cables in the corresponding position. Therefore, other cables can be arranged inside the device, thereby increasing the scope of application of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is described below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on this embodiment, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 8An embodiment of a super charging pile test device includes a test mechanism 1 and a control structure 2 installed on the test mechanism 1, the control structure 2 is used to open and close and control the test mechanism 1, the test mechanism 1 includes an outer shell 11, a first handle 12 is fixedly installed on the upper end of the outer shell 11, and a universal wheel 13 is provided at the lower end of the outer shell 11. Through the cooperation between the first handle 12 and the universal wheel 13, the operator holds the first handle 12, and the device can be moved or lifted, which is convenient for carrying and using the device.

[0034] A mounting mechanism 3 is installed on one side of the test mechanism 1. The mounting mechanism 3 includes a first inner panel 31 rotatably mounted on one side of the outer shell 11 and a second inner panel 32 fixedly mounted on one side of the first inner panel 31. The first inner panel 31 and the second inner panel 32 are combined into an L-shaped structure and are rotatably mounted on one side of the outer shell 11. When the device is moving, the cables used for connection are accommodated in the first inner panel 31 and the second inner panel 32 and will not be dragged on the ground, which not only increases the cable accommodation area but also reduces the wear on the cables. When one end of the opening of the first inner panel 31 and the second inner panel 32 is in contact with the inner wall of the outer shell 11, there is no gap on the periphery thereof, which also plays a certain role in dust and water prevention and has a good protection effect.

[0035] The first inner panel 31 is rotated outward, so that the first inner panel 31 and the second inner panel 32 are unfolded. After unfolding, the openings of the two panels face upward, which is convenient for taking the cables and increases the placement space of the cables after being stretched.

[0036] A supporting mechanism 5 is also installed on one side of the testing mechanism 1. The supporting mechanism 5 includes a first connecting rod 51. The first connecting rod 51 is arranged on one side of the outer shell 11 through a hinge, and the opening and closing angle of the hinge is 90 degrees. The first connecting rod 51 is also arranged at the lower end of the first inner panel 31. One end of the first connecting rod 51 is rotatably installed with a second connecting rod 54. When the first inner panel 31 and the second inner panel 32 are unfolded, the first connecting rod 51 can be driven to rotate. After the first connecting rod 51 is completely rotated, it is perpendicular to the ground. Therefore, the unfolded first inner panel 31 is also parallel to the ground, which is convenient for accommodating the cable. The operator rotates the second connecting rod 54 to make the second connecting rod 54 perpendicular to the ground, which is convenient for supporting the first connecting rod 51 and the first inner panel 31, thereby increasing the bearing capacity of the cable. The second connecting rod 54 is supported on the ground, which increases the friction at the bottom of the device, reduces the movement of the universal wheel 13 when the device is in use, and ensures the stability of the device when in use.

[0037] A heat dissipation hole 14 is installed on one side of the outer shell 11 to facilitate the heat dissipation of the internal components of the test mechanism 1. A first avoidance groove 15 is opened on one side of the outer shell 11, and a second avoidance groove 16 connected to the first avoidance groove 15 is opened on the upper end of the outer shell 11. The first avoidance groove 15 and the second avoidance groove 16 are combined into an L-shaped structure. The first avoidance groove 15 and the second avoidance groove 16 are respectively adapted to the first inner embedded plate 31 and the second inner embedded plate 32. After the first inner embedded plate 31 and the second inner embedded plate 32 are folded, they are completely accommodated in the first avoidance groove 15 and the second avoidance groove 16, so that the surface of the device is still a rectangular structure, which reduces the footprint of the device and makes it easier to avoid obstacles when moving.

[0038] When the device is moved, the first inner panel 31 and the second inner panel 32 need to be folded up, and the cables are located in the first avoidance groove 15 and the second avoidance groove 16 and will not hang on the ground, thereby reducing the wear on the cables when the device is moved and achieving good protection effect.

[0039] A avoidance hole 18 is provided at the lower end of the first avoidance groove 15, and the avoidance hole 18 is connected to the inner cavity of the outer shell 11. The cables of the electrical components of the test mechanism 1 can extend from the avoidance hole 18. A liquid cooling oil observation window is also provided on one side of the outer shell 11 to facilitate observation of the liquid cooling oil capacity of the device.

[0040] Side panels 33 are installed at both ends of the first inner panel 31 and the second inner panel 32. A second handle 34 is installed between the two side panels 33 for rotation. The second handle 34 is a cylindrical structure. The operator holds the second handle 34 to facilitate unfolding the first inner panel 31 and the second inner panel 32. A limit lock block 36 is fixedly installed at one end of the second inner panel 32 to facilitate fixing one end of the cable.

[0041] A charging gun seat 17 is installed on the side wall of the second avoidance groove 16, and a test mechanism 4 is installed on one side of the test mechanism 1. The test mechanism 4 includes a connecting cable 41 arranged on one side of the outer shell 11 and a gun head body 42 fixedly installed on one side of the connecting cable 41. The gun head body 42 used to connect the test mechanism 1 can be plugged into the charging gun seat 17, which is convenient for fixing one end of the gun head body 42. After the first inner panel 31 and the second inner panel 32 are closed, the charging gun seat 17 and the gun head body 42 are also located in this enclosed space, which is convenient for waterproofing and anti-collision when the device is not in use. To a certain extent, it has the functions of storage and portability, and the protection effect is good.

[0042] The connection cable 41 for connecting the gun head body 42 is located in the first inner plate 31, so as to reduce the wear of the connection cable 41 when the device moves.

[0043] The support mechanism 5 also includes an elastic block 52 fixedly mounted on one side of the first connecting rod 51. After the first connecting rod 51 is unfolded, the second connecting rod 54 is not unfolded. At this time, the universal wheel 13 has no limiting effect and can drive the unfolded first inner panel 31 to move. The bottom of the first inner panel 31 is overlapped on the elastic block 52. The elastic block 52 can be any elastic structure such as rubber, spring, etc., which can play a buffering role for the first inner panel 31.

[0044] A second slide groove 53 is provided on the first connecting rod 51, and a second connecting rod 54 is rotatably mounted on the inner wall of the second slide groove 53. A third connecting rod 55 is rotatably mounted on one end of the second connecting rod 54. The combined length of the second connecting rod 54 and the third connecting rod 55 is adapted to the length of the second slide groove 53. When the second connecting rod 54 and the third connecting rod 55 are folded, both can be completely accommodated in the second slide groove 53 for storage.

[0045] After the second connecting rod 54 and the third connecting rod 55 are unfolded, the second connecting rod 54 is perpendicular to the ground and the third connecting rod 55 overlaps the ground, which further increases the contact area and friction between the device and the ground, limits the movement of the universal wheel 13, and greatly ensures the stability of the device.

[0046] A plurality of first slide grooves 35 equidistantly distributed are provided on the side wall of the first embedded panel 31, and a sorting mechanism 6 is installed inside the mounting mechanism 3. The sorting mechanism 6 comprises a sliding block 61 slidably mounted in the first slide groove 35 and a rotating block 62 rotatably mounted on the upper end of the sliding block 61, and clamping plates 64 are fixedly mounted on both sides of the upper end of the rotating block 62, and a rotating roller 65 is rotatably mounted between the two clamping plates 64.

[0047] A mounting buckle 66 is rotatably mounted on the outer periphery of the rotating roller 65. Multiple mounting buckles 66 are alternately distributed left and right and are all mounted on one side of the first slide groove 35. A mounting opening 67 is opened on one side of the mounting buckle 66. The connecting cable 41 is clamped in the mounting buckle 66 through the mounting opening 67. After the installation, the connecting cable 41 is distributed in a snake shape on the side wall of the first embedded panel 31, which is organized in an orderly manner, occupies a small area, and is easy to accommodate longer connecting cables 41.

[0048] The mounting buckle 66 is rotated on the sliding block 61 through the rotating block 62, and can be adaptively adjusted according to different installation angles of the connecting cable 41. The rotating block 62 slides in the first sliding groove 35 through the sliding block 61, and can be adjusted according to the length of the connecting cable 41, thereby increasing the flexibility during the installation of the connecting cable 41.

[0049] The first elastic member 63 is fixedly installed at one end of the sliding block 61, and one end of the first elastic member 63 is fixedly connected to the inner wall of the second slide groove 53. There are multiple first elastic members 63, and the closer the first elastic member 63 is to the second inner panel 32, the greater the elasticity. Therefore, when it is necessary to stretch the connecting cable 41 for use, the sliding block 61 at one end of the connecting cable 41 is pulled to stretch the first elastic member 63 at the corresponding position until the first elastic member 63 is stretched to the longest, and the sliding block 61 also approaches the middle part of the first slide groove 35, and so on and so forth until the connecting cable 41 approaches a straight line, which is convenient for stretching the connecting cable 41. After the connecting cable 41 is relaxed, under the action of the first elastic member 63, the first elastic member 63 at the end far away from the second inner panel 32 is first contracted until the multiple first elastic members 63 are reset, which is convenient for re-arranging the connecting cable 41. Therefore, it is convenient to store the connecting cable 41 and move the device, reducing the work of the operator to arrange.

[0050] The elasticity of the multiple first elastic members 63 is different, and their elasticity gradually increases or decreases. When stretched, the end with greater elasticity is stretched first, and when contracted, the end with less elasticity is contracted first. This not only facilitates the fixation of one end of the connecting cable 41, but also greatly increases the flexibility of resetting the connecting cable 41.

[0051] It should be noted that this solution only uses the connecting cable 41 as an example, and the arranging mechanism 6 can arrange different cables and can be debugged according to actual usage.

[0052] A limiting mechanism 7 is provided on one side of the testing mechanism 1, and the limiting mechanism 7 includes a limiting protrusion 71 fixedly mounted on the groove wall of the first avoidance groove 15. A plurality of limiting protrusions 71 are provided, and the positions of the plurality of limiting protrusions 71 are adapted to the second slide groove 53. The width of the middle portion of the limiting protrusion 71 is greater than the width of both sides thereof. When the first embedded panel 31 is closed, one end of the mounting buckle 66 contacts the thinnest portion of the limiting protrusion 71.

[0053] The first slide groove 35, the mounting buckle 66 and the limiting protrusion 71 are adapted to each other. When the first inner panel 31 needs to be retracted upward, the operator needs to loosen the connecting cable 41 in advance to reset it. When some of the mounting buckles 66 fail to reset successfully, the mounting buckles 66 will be located at the thicker position of the limiting protrusion 71, and the mounting buckle 66 will roll toward the thinner position on the limiting protrusion 71. Therefore, when the first inner panel 31 is completely retracted, the mounting buckle 66 will drive the connecting cable 41 to automatically roll toward the end point of the first slide groove 35 until multiple connecting cables 41 are reset together, further increasing the arrangement effect of the device on the connecting cables 41, and the use effect is good.

[0054] A snap-fit ​​groove 72 is provided on the limiting protrusion 71, and a snap-fit ​​block 73 is rotatably installed on the snap-fit ​​groove 72. A second elastic member 74 is commonly connected between the snap-fit ​​block 73 and the groove wall of the snap-fit ​​groove 72. Under the action of the snap-fit ​​block 73 and the second elastic member 74, the snap-fit ​​block 73 is flush with the surface of the limiting protrusion 71, which facilitates the rolling of the mounting buckle 66.

[0055] There are multiple clamping grooves 72, and other cables can squeeze the clamping block 73 and the second elastic member 74 and be clamped in the clamping groove 72. After the clamping is completed, the clamping block 73 is reset under the action of the second elastic member 74, and the cables in the corresponding position can be locked and limited. Therefore, other cables can be arranged inside the device, which increases the scope of application of the device.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
