Description

Technical Field

[0001] This utility model relates to the field of misalignment experiments, specifically to a misalignment experiment device. Background Technology

[0002] In actual use, car charging guns may encounter various offset operations under the action of external forces. Offset movement of the charging gun can lead to problems such as poor contact of the charging contacts and unstable current, and may generate electric sparks. Therefore, offset testing can evaluate the performance stability of the charging gun under offset operation and ensure that the charging gun is safe in different usage scenarios.

[0003] The existing charging gun offset test device still has the following problems when used: the previous device applied an external force to the charging gun to conduct offset test by pushing it manually. The manual pushing is not good at simulating the effect of different external forces applied to the charging gun. Moreover, if the test environment is harsh, such as testing in hot outdoor environment, it is difficult to simulate the pushing force manually.

[0004] Therefore, it is necessary to invent an offset and misalignment experimental device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an offset misalignment experimental device to solve the problems mentioned in the background art. The previous devices applied an external force to the charging gun to perform offset tests by pushing it manually. However, pushing manually does not effectively simulate the effects of different external forces applied to the charging gun. Furthermore, if the test environment is harsh, such as in a hot outdoor environment, it is difficult to simulate the pushing force manually.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an offset misalignment experimental device, including a mounting base, an mounting plate movably mounted on the outside of the mounting base, a mounting bracket fixedly mounted on the side wall of the mounting plate, and a telescopic cylinder fixedly mounted on the end side of the mounting bracket. An end plate is fixedly mounted on the extension end of the telescopic cylinder, and a mounting sleeve is movably fitted on the outside of the end plate through a disassembly and assembly assembly. A charging gun is inserted into the plug-in test port installed inside the mounting base.

[0007] Preferably, there are four mounting brackets in total, and the four mounting brackets are arranged in a ring at equal angles.

[0008] Preferably, the mounting sleeve has a columnar groove inside, and the inner wall of the columnar groove is attached to the outer wall of the end plate to achieve a sliding connection. In this way, the movement of the telescopic cylinder drives the mounting sleeve to exert a force on the charging gun inserted into the charging slot, thereby simulating the situation where the charging gun is shaken by an external force.

[0009] Preferably, the disassembly and assembly assembly includes a movable cavity pre-set inside the end plate, and a movable block is elastically connected inside the movable cavity by a spring. The movable block is snapped into the mounting sleeve through a pre-reserved snap-fit ​​groove. The snap-fit ​​groove is connected to the pre-reserved columnar groove inside the mounting sleeve, which facilitates the snap-fit ​​of the mounting sleeve onto the outside of the end plate. The silicone material at the front end of the mounting sleeve contacts the outer wall of the charging gun to prevent scratching the charging gun in the laboratory.

[0010] Preferably, there are two movable blocks, and the two movable blocks are arranged symmetrically with reference to the central axis of the end plate.

[0011] Preferably, side blocks are fixedly installed on both sides of the end of the movable block, and the outer walls of the movable block and the side blocks are attached to the inner wall of the movable cavity to achieve a sliding connection between the upper and lower parts.

[0012] Preferably, the movable block has an arc-shaped surface at one end near the mounting bracket, and the arc-shaped surface is in contact with the arc-shaped inner wall of the snap-fit ​​groove to achieve a sliding connection. In this way, pulling the mounting sleeve outward causes the arc-shaped inner wall of the snap-fit ​​groove to move and contact the arc-shaped surface of the movable block, and abuts the movable block to move towards the interior of the movable cavity, which facilitates the removal and replacement of the mounting sleeve.

[0013] Preferably, the disassembly and assembly assembly further includes a notch pre-set at the end of the mounting sleeve, and there are two notches. The two notches are symmetrically arranged with reference to the central axis of the mounting sleeve as the axis of symmetry. The inner wall of the notch is reserved with an inclined surface, wherein the inclined surface is in contact with the side of the movable block that does not have an arc surface and achieves a sliding connection. When it is necessary to press the mounting sleeve and the end plate for installation, the inclined surface contacts the side of the movable block in sync with the movement of the mounting sleeve. The continuous movement of the mounting sleeve causes the inclined surface to press against the movable block and move the movable block towards the interior of the movable cavity, which facilitates the installation of the mounting sleeve.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model inserts the charging gun into the plug-in test port. The telescopic cylinder moves to drive the mounting sleeve of the end plate to move and contact the outer wall of the charging gun, and pushes the charging gun to simulate the misaligned movement state of the charging gun being pushed by an external force, thereby completing the experiment. This eliminates the need for manual force application, making the test more efficient. At the same time, the force level is recorded to ensure the authenticity and accuracy of the experiment.

[0016] 2. Pulling the mounting sleeve outward causes the arc-shaped inner wall of the snap-fit ​​groove to move and contact the arc-shaped surface of the movable block, thus pressing against the movable block and moving it towards the interior of the movable cavity. This facilitates the removal and replacement of the mounting sleeve after prolonged use and wear. Simultaneously, when the mounting sleeve is pressed and installed with the end plate, the inclined surface of the mounting sleeve moves in sync with the end side of the movable block. The continuous movement of the mounting sleeve causes the inclined surface to press against the movable block, thus pressing against the movable block and moving it towards the interior of the movable cavity, facilitating the installation of the mounting sleeve.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-4The offset and misalignment experimental device shown includes a mounting base 1, an mounting plate 3 is movably mounted on the outside of the mounting base 1, a mounting bracket 4 is fixedly mounted on the side wall of the mounting plate 3, a telescopic cylinder 5 is fixedly mounted on the end side of the mounting bracket 4, an end plate 6 is fixedly mounted on the extended end of the telescopic cylinder 5, and a mounting sleeve 7 is movably fitted on the outside of the end plate 6 through a disassembly and assembly assembly 8. A charging gun 2 is inserted into the plug-in test port installed inside the mounting base 1.

[0026] In this way, the charging gun 2 is inserted into the test port. The telescopic cylinder 5 moves and drives the mounting sleeve 7 of the outer sleeve of the end plate 6 to move and contact the outer wall of the charging gun 2, and pushes the charging gun 2 to simulate the misaligned movement state of the charging gun 2 being pushed by an external force, thereby completing the experiment.

[0027] There are four mounting brackets 4 in total, and the four mounting brackets 4 are arranged in a ring at the same angle. This allows the four sets of mounting sleeves 7 to contact the charging gun 2, ensuring that the charging gun 2 can be subjected to forces from different directions. The mounting sleeve 7 has a columnar groove inside, and the inner wall of the columnar groove is attached to the outer wall of the end plate 6 to achieve a sliding connection.

[0028] The telescopic cylinder 5 moves, causing the mounting sleeve 7 to move and apply force to the charging gun 2 inserted into the charging slot, thus simulating the situation where the charging gun 2 is shaken by an external force. This eliminates the need for manual force application, making the testing more efficient. At the same time, the force is recorded, ensuring the authenticity and accuracy of the experiment.

[0029] The disassembly and assembly component 8 includes a movable cavity 801 pre-installed inside the end plate 6, and a movable block 802 is elastically connected inside the movable cavity 801 by a spring 804. The movable block 802 is snapped into the mounting sleeve 7 with a pre-reserved snap-fit ​​groove 806. The snap-fit ​​groove 806 is connected to the pre-reserved columnar groove inside the mounting sleeve 7.

[0030] This facilitates the external mounting of the end plate 6 with the sleeve 7. The silicone material at the front end of the sleeve 7 contacts the outer wall of the charging gun 2 to prevent scratching of the charging gun 2 in the laboratory.

[0031] Two movable blocks 802 are provided, and the two movable blocks 802 are arranged symmetrically with reference to the central axis of the end plate 6. Side blocks 803 are fixedly installed on both sides of the end of the movable block 802, and the outer walls of the movable block 802 and the side blocks 803 are attached to the inner wall of the movable cavity 801 to achieve a sliding connection. An arc-shaped surface 805 is provided on the side of the movable block 802 near the mounting bracket 4, and the arc-shaped surface 805 is attached to the arc-shaped inner wall of the snap-fit ​​groove 806 to achieve a sliding connection.

[0032] Pulling the mounting sleeve 7 outward causes the arc-shaped inner wall of the snap-fit ​​groove 806 to move and contact the arc-shaped surface 805 of the movable block 802, thus pressing against the movable block 802 and moving it towards the interior of the movable cavity 801. This facilitates the removal and replacement of the mounting sleeve 7 after it wears out.

[0033] The assembly and disassembly component 8 also includes a notch 807 pre-set at the end of the mounting sleeve 7, and there are two notches 807. The two notches 807 are symmetrically arranged with reference to the central axis of the mounting sleeve 7. The inner wall of the notch 807 is reserved with an inclined surface 808, which is in contact with the side of the movable block 802 without the arc surface 805 and achieves a sliding connection.

[0034] When it is necessary to press the mounting sleeve 7 and the end plate 6 together, the inclined surface 808 moves synchronously with the movement of the mounting sleeve 7 and contacts the end side of the movable block 802. The continuous movement of the mounting sleeve 7 causes the inclined surface 808 to abut against the movable block 802 and move against the movable block 802, so that the movable block 802 moves towards the interior of the movable cavity 801, which facilitates the installation of the mounting sleeve 7.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
