Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of charging pile detectors, and in particular to a fully automatic tester for charging piles. Background Art
[0002] Nowadays, the application of charging piles is becoming more and more extensive, and its performance detection is crucial, which makes the role of a fully automatic tester for charging piles very important. However, the existing fully automatic testers for charging piles face many problems in actual use.
[0003] During the transportation process, the tester often encounters various bumps and vibrations. Due to the lack of efficient shock absorption measures, the internal structure of traditional testers is simple, and mostly uses a single elastic element or a simple cushion for shock absorption. When encountering large bumps, these shock absorption methods cannot effectively buffer, resulting in the internal precision electrical components of the tester being extremely vulnerable to impact. This not only may cause problems such as loose internal wiring and short circuits, but also affects the detection accuracy and stability of the tester, and even directly damages the tester, greatly increasing the maintenance cost and the equipment replacement frequency, seriously affecting the production efficiency.
[0004] Moreover, in the actual test work scenario, traditional testers lack a flexible adjustment structure. Different test environments and test requirements require the tester to be able to flexibly adjust its posture and height, but traditional testers are difficult to adjust quickly and conveniently according to the actual situation. For example, when performing plug-and-unplug test operations, the tester body cannot be effectively supported and its position adjusted, bringing great inconvenience to the test work and reducing the efficiency and accuracy of the test work.

[0010] As a preferred embodiment of the fully automatic tester for the charging pile of the present invention, the following is provided: The end of the connection column extends to the outer wall of the first sleeve, and a placement plate is arranged at the end of the connection column. The placement plate is arranged inside the sealing cavity on the outer wall of the first sleeve, and support columns are arranged in an array on the outer wall of the placement plate.

[0012] As a preferred embodiment of the fully automatic tester for the charging pile of the present invention, the following is provided: The second sleeve slides inside the activity cavity. A vertical rod is arranged on the inner wall of the second sleeve, and a first elastic member is sleeved on the outer wall of the vertical rod.

When encountering bumps during transportation, it can adaptively adjust according to the vibration magnitude. During small bumps, through the buffering of the fourth elastic member, the slow flow of hydraulic oil, and the first elastic member and the second elastic member, the tester body is kept stable; during large bumps, by the synergistic effect of the connecting column, the support column, the friction block and the friction ring, the position of the moving column is quickly locked to prevent the tester body from shaking greatly, realizing precise response to different bump degrees, improving the stability and reliability of the tester under various transportation conditions, avoiding damage to internal electrical components due to bumps.

Detailed implementation manners
[0027] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings of the specification.
[0028] Many specific details are set forth in the following description to facilitate a thorough understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.
[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments. Embodiment 1
[0030] Referring to Figures 1 to 6 , this is the first embodiment of the present invention, and this embodiment provides a full-automatic tester for charging piles.
[0031] Specifically, the main body component 100 includes a transportation housing 101, a tester body 102 provided on the inner wall of the transportation housing 101, and a receiving cavity 103 provided at the end of the tester body 102; The buffer assembly 200 provided on the inner wall of the receiving cavity 103 includes a first sleeve 201 provided at the end of the tester body 102, and a second sleeve 202 is further provided inside the first sleeve 201; A moving component is provided inside the first sleeve 201 and the moving component cooperates with the second sleeve 202. The moving component includes a moving column 203 and a fourth elastic member 205 provided inside the first sleeve 201. The moving column 203 cooperates with the fourth elastic member 205 inside the first sleeve 201 for buffering.
[0032] Among them, the receiving cavity 103 is an active space inside the transportation housing 101 at the bottom of the tester body 102. A plurality of buffer assemblies 200 are arrayed and installed inside for damping the tester body 102 to reduce the influence caused by the bumps generated during transportation.
[0033] Inside the buffer assembly 200, the first sleeve 201 is sleeved inside the second sleeve 202. The top end of the first sleeve 201 is connected to the bottom of the tester body 102, while the second sleeve 202 is connected to the bottom plate of the transportation housing 101, that is, the position at the bottom of the receiving cavity 103. When vibration occurs, the second sleeve 202 moves up and down inside the first sleeve 201, and at the same time drives the internal moving component to move. The moving component will adaptively adjust the amplitude of movement according to the magnitude of the generated vibration, so that the tester body 102 can adapt to the vibration force generated by different bumps and perform buffering. Embodiment 2
[0034] Refer to Figures 4 to 8 , which is the second embodiment of the present invention, and this embodiment is implemented based on the previous embodiment.
[0035] Specifically, a moving cavity 2011 is provided on the inner wall of the first sleeve 201, and the moving column 203 moves inside the moving cavity 2011 and its outer wall fits against the inner wall of the first sleeve 201. A connecting cavity 2031 is provided on the inner wall of the moving column 203, and a rack 2032 is further provided on the inner wall of the connecting cavity 2031.
[0036] Among them, the moving column 203 is installed inside the moving cavity 2011. At the same time, a fourth elastic member 205 is provided at the top of the moving column 203. The fourth elastic member 205 is located between the top of the moving column 203 and the inner wall of the first sleeve 201. Hydraulic oil is provided inside the moving cavity 2011. The outer wall of the moving column 203 is tightly attached to the moving cavity 2011 to play a sealing role. At the same time, according to Figure 6It can be seen that a flow hole is provided in the center of the moving column 203, enabling the moving column 203 to move inside the movable cavity 2011.
[0037] Preferably, a first connection channel 2012 and a second connection channel 2013 are provided on the inner wall of the movable cavity 2011, and the ends of the first connection channel 2012 and the second connection channel 2013 are connected to the inner wall of the connection cavity 2031.
[0038] Among them, the bottom port of the first connection channel 2012 and the upper port of the second connection channel 2013 are both connected to the connection cavity 2031 in the middle of the moving column 203. When the moving column 203 moves inside the movable cavity 2011 through the first connection channel 2012 and the second connection channel 2013, the hydraulic oil inside is circulated, improving the moving speed of the moving column 203 inside the movable cavity 2011.
[0039] A connection column 204 is arranged inside the connection cavity 2031, and the end of the connection column 204 extends to the outer wall of the first sleeve 201. A connection gear 2041 is arranged on the outer wall of the connection column 204, and the connection gear 2041 meshes with the rack 2032 on the inner wall of the moving column 203. When the moving column 203 moves on the inner wall of the movable cavity 2011, it drives the connection gear 2041 to rotate.
[0040] Among them, the connection column 204 is fixed inside the first sleeve 201. As Figure 7 can be seen, the connection column 204 also penetrates out of the connection cavity 2031. The connection gear 2041 on the surface meshes with the rack 2032 inside the connection cavity 2031. When the moving column 203 is driven by the second sleeve 202 at the bottom to move inside the movable cavity 2011, the movement of the rack 2032 drives the connection column 204 to rotate, and the end of the connection column 204 extending to the outside of the first sleeve 201 also rotates.
[0041] The end of the connection column 204 extends to the outer wall of the first sleeve 201, and a mounting plate 2042 is arranged at the end of the connection column 204. The mounting plate 2042 is arranged inside the sealing cavity 2014 on the outer wall of the first sleeve 201, and a plurality of support columns 2043 are arranged in an array on the outer wall of the mounting plate 2042. The support columns 2043 move along the inner wall of the sealing cavity 2014 with the connection column 204.
[0042] Among them, the mounting plate 2042 is installed at the position where the connection column 204 is outside the first sleeve 201, and rotates synchronously inside the sealing cavity 2014 with the connection column 204. As Figure 8 shown, a plurality of support columns 2043 are arranged in an array on the surface of the mounting plate 2042. As the mounting plate 2042 rotates synchronously inside the sealing cavity 2014 and is affected by the rotation speed of the connection column 204, the movement state of the support columns 2043 will change.
[0043] The outer wall of the support column 2043 is provided with a friction block 2044, and the friction block 2044 is matched with a friction ring 2015 arranged on the inner wall of the sealing cavity 2014. The inner wall of the support column 2043 is provided with a convex block 2045, and a third elastic member 2046 is connected to the outer wall of the convex block 2045. The third elastic member 2046 is used to pull the support column 2043.
[0044] Wherein, one end of the third elastic member 2046 is fixed on the surface of the placement plate 2042, and the other end is connected to the convex block 2045 on the surface of the support column 2043. The support column 2043 is pulled by the third elastic member 2046, so that the support column 2043 is pulled inward in the initial state or at a low rotation speed, avoiding contact with the friction ring 2015 on the inner wall of the sealing cavity 2014.
[0045] When a large bump occurs, causing the vibration amplitude of the tester body 102 inside the transport housing 101 to be relatively large, the second sleeve 202 pushes the moving column 203 to move a large distance inside the movable cavity 2011. At this time, the moving column 203 moves at a relatively fast speed inside the movable cavity 2011, so that when the rotation speed of the connecting column 204 is in a high state, the support column 2043 on the outer wall of the placement plate 2042 expands outward under the influence of rotational centrifugal force, and the friction block 2044 on the outer wall contacts the friction ring 2015, causing the connecting column 204 to stop rotating, and the moving column 203 to stop moving inside the movable cavity 2011, temporarily fixing the height of the tester body 102 inside the transport housing 101, and preventing the tester body 102 from shaking significantly inside the transport housing 101 at this time, affecting the installation stability of the internal electrical components.
[0046] When the bump is small, the moving column 203 is driven by the second sleeve 202 to move inside the movable cavity 2011. Through the fourth elastic member 205 inside and the slow flow of hydraulic oil, the tester body 102 is in a relatively stable state inside the transport housing 101, avoiding the bump from impacting the internal electrical components.
[0047] Preferably, the second sleeve 202 slides inside the movable cavity 2011. The inner wall of the second sleeve 202 is provided with a vertical rod 2021, and a first elastic member 2022 is sleeved on the outer wall of the vertical rod 2021. A second elastic member 2023 is also provided at the end of the vertical rod 2021.
[0048] Among them, the bottom position of the vertical pole 2021 is fixed at the bottom of the accommodating chamber 103. When bumps occur, the second sleeve 202 moves as a whole inside the movable chamber 2011 on the inner wall of the first sleeve 201. At the same time, the hydraulic oil inside the movable chamber 2011 and the fourth elastic member 205 cooperate to perform shock absorption. At the same time, the first elastic member 2022 on the outer wall of the vertical pole 2021 and the second elastic member 2023 on the top of the vertical pole 2021 also perform shock absorption and buffering for the second sleeve 202, and further cooperate with the internal components of the first sleeve 201 to ensure the stability of the tester body 102 during transportation.
[0049] In summary, during use, the buffer assembly 200 of the fully automatic charging pile tester achieves adaptive shock absorption through a multi-stage linkage structure during transportation. When the transport shell 101 is bumpy, the second sleeve 202 connected to the bottom of the accommodating chamber 103 slides up and down within the movable chamber 2011 of the first sleeve 201, pushing the internal movable column 203 to move synchronously. The outer wall of the movable column 203 fits the movable chamber 2011 and allows hydraulic oil to circulate through the central flow hole and the first and second connecting channels 2012 and 2013. The fourth elastic member 205 at the top absorbs vibration energy, while the vertical rod 2021 on the inner wall of the second sleeve 202 drives the first and second elastic members 2022 and 2023 to further buffer.
[0050] When encountering a small bump, the moving column 203 moves at a low speed, and its inner wall rack 2032 drives the connecting gear 2041 to rotate at a low speed. The placement plate 2042 and the support 2043 at the end of the connecting column 204 shrink inward under the tension of the third elastic member 2046. The friction block 2044 does not contact the friction ring 2015, allowing the connecting column 204 to rotate freely. The slow flow of hydraulic oil and the cooperation of the elastic member realize flexible buffering.
[0051] When encountering a large bump, the moving column 203 moves at high speed, the rack 2032 drives the connecting gear 2041 to rotate at high speed, and the placement plate 2042 drives the pillar 2043 to open outward due to the centrifugal force to overcome the pulling force of the third elastic member 2046. The friction block 2044 contacts the friction ring 2015 to generate friction resistance, forcing the connecting column 204 to stop rotating, and then lock the position of the moving column 203, temporarily fixing the height of the tester body 102 to avoid large shaking. At the same time, the elastic member still assists in absorbing residual impact.
[0052] The linear motion is converted into rotational motion by using the connecting gear 2041 and the rack 2032. Whether the friction block 2044 and the friction ring 2015 are in contact is driven by centrifugal force, automatically distinguishing the flexible buffer during small bumps from the rigid lock during large bumps, avoiding the failure problem of the traditional shock-absorbing structure under strong impacts. At the same time, the damping effect of the internal hydraulic oil, the elastic buffer of the elastic member, and the friction braking form protection. It can not only absorb the low-frequency small vibration energy through the slow flow of the hydraulic oil and the deformation of the elastic member, but also prevent the excessive displacement of the tester body 102 through friction locking during high-frequency strong impacts, comprehensively protecting the internal precision devices. Embodiment 3
[0053] Refer to Figures 1 to 3 , which is the third embodiment of the present invention and is implemented based on the previous embodiment.
[0054] Specifically, a fixed frame 301 is further provided inside the accommodating cavity 103. A slideway 3011 is opened on the outer wall of the fixed frame 301. A first hinge rod 3012 is hinged to the inner wall of the fixed frame 301. A second hinge rod 3013 is also hinged to the outer wall of the first hinge rod 3012, and the end of the second hinge rod 3013 extends to the inner wall of the slideway 3011 and is slidably matched with it. The ends of the first hinge rod 3012 and the second hinge rod 3013 are hinged and located at the end of the tester body 102.
[0055] Among them, the fixed frame 301 is fixed inside the accommodating cavity 103. The first hinge rod 3012 and the second hinge rod 3013 are respectively hinged to the inner wall. At the same time, the top positions of the first hinge rod 3012 and the second hinge rod 3013 are hinged together, and are located below the tester body 102 and not fixed to the bottom of the tester body 102. And the bottom of the second hinge rod 3013 slides inside the slideway 3011. By sliding the second hinge rod 3013, the height of the hinge point between the two is adjusted.
[0056] Preferably, a moving rod 3014 is provided inside the second hinge rod 3013, and a screw rod 302 is provided inside the moving rod 3014, and the end of the screw rod 302 extends to the outer wall of the transportation housing 101.
[0057] Among them, a screw rod 302 is installed in the middle of the moving rod 3014 connected to the inner wall of the second hinge rod 3013. By rotating the screw rod 302, the position of the bottom of the second hinge rod 3013 inside the slideway 3011 is synchronously adjusted, thereby realizing the adjustment of the height of the hinge point.
[0058] By adjusting the height of the hinge point, during transportation, the screw 302 is used to move the hinge point away from the bottom of the tester body 102, which is beneficial to the operation of the buffer assembly 200. When testing work needs to be carried out, since plugging and unplugging operations are required, at this time, the height of the hinge point can be increased by the screw 302 to support the tester body 102, facilitating its use during work.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
