[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.
[0028] Reference Figure 1-6 , which is the first embodiment of the present utility model, provides a monitoring device for a charging gun plug-in tester. The monitoring device comprises a housing 1, a socket 2 mounted inside the housing 1, a driving member 3 mounted inside the housing 1, and a clamping member 4 mounted at one end of the driving member 3. The clamping member 4 is tilted to facilitate fixing the position of the charging gun handle.
[0029] The clamping member 4 includes a supporting plate 41 installed at one end of the driving member 3, and the surface of the supporting plate 41 is fixedly connected to a fixed seat 42, and a movable seat 43 is installed on the surface of the supporting plate 41 and on the other side of the fixed seat 42. The interiors of the movable seat 43 and the fixed seat 42 are fixedly connected with rubber balls 44 and rubber strips 45, and the rubber balls 44 are located on one side of the rubber strip 45. The rubber balls 44 and the rubber strips 45 are both arranged in a circular array. The rubber balls 44 and the rubber strips 45 can increase the friction with the position of the charging gun handle, making the charging gun more stably fixed and preventing the charging gun from offsetting, thereby affecting the focusing effect, and the interiors of the fixed seat 42 and the movable seat 43 are both arc-shaped, and the rubber balls 44 and the rubber strips 45 are located at the arc.
[0030] A positioning groove 47 is provided on the surface of the fixed seat 42, and a positioning block 46 is fixedly connected to the inner side of the movable seat 43. The positioning block 46 is located inside the positioning groove 47 and is movably connected thereto. The positioning groove 47 and the positioning block 46 are both provided at the four corners of the fixed seat 42 and the movable seat 43, which can conveniently fix charging guns of similar specifications. By fixing the socket 2 in the designated area and fixing the charging gun in the designated area through the fixed seat 42 and the movable seat 43, the focusing operation can be completed without the need for manual visual inspection, which further ensures accuracy.
[0031] One end of the movable seat 43 and the end close to the supporting plate 41 are fixedly connected with a T-block 431 and a sliding block 432. There are two groups of T-blocks 431. The sliding block 432 is located on the inner side of the two groups of T-blocks 431. Guide grooves 433 are provided on both sides of the sliding block 432. The T-block 431 can ensure the stability of the movable seat 43 during movement, and the sliding block 432 is used to drive the movement of the movable seat 43.
[0032] The inner side of the supporting plate 41 is provided with a T-slot 411 and a slide groove 412. There are two groups of T-slots 411. The slide groove 412 is located on the inner side of the two groups of T-slots 411. The inner side of the slide groove 412 is fixedly connected with a guide bar 413. The setting of the guide bar 413 can make the sliding block 432 more stable when moving.
[0033] The T-block 431 is located inside the T-slot 411 and is movably connected thereto. The sliding block 432 is located inside the slide groove 412 and is movably connected thereto. The guide groove 433 is located on the surface of the guide bar 413 and is movably connected thereto to ensure the stability of the movable seat 43.
[0034] The internal thread of the sliding block 432 is connected to a screw 48, which is located inside the slide groove 412 and is rotatably connected to it. One end of the screw 48 extends to the outside of the supporting plate 41 through the slide groove 412. One end of the screw 48 is rotatably connected to the supporting plate 41, and at the same time, the sliding block 432 can be used to conveniently drive the moving seat 43 to move along the inner side of the supporting plate 41.
[0035] The driving member 3 includes a sleeve 31 installed inside the shell 1. The sleeve 31 is located at one end away from the socket 2. A screw rod 32 and a slide rod 33 are installed inside the sleeve 31. The screw rod 32 is located on one side of the slide rod 33. A stepper motor 34 is installed at one end of the sleeve 31. The output end of the stepper motor 34 extends to the inside of the sleeve 31 and is fixedly connected to the screw rod 32. A slider 37 is installed on the surface of the screw rod 32 and the slide rod 33. The slider 37 is threadedly connected to the screw rod 32 and movably socketed with the slide rod 33. The screw rod 32 is rotatably connected to the sleeve 31, and the slide rod 33 is fixedly connected to the sleeve 31.
[0036] The interior of the housing 31 is fixedly connected with equidistantly arranged connecting columns 36, and the top of the connecting columns 36 is fixedly connected with a top cover 35. The top cover 35 is located on the top of the connecting columns 36. The top cover 35 is connected to the housing 31 through the connecting columns 36. The top cover 35 is located inside the slider 37 and is movably connected to it. A groove is provided inside the slider 37, and the top cover 35 is located inside the groove and is movably connected to the slider 37 through the groove. In addition, a cavity is also provided inside the slider 37 to prevent it from getting stuck with the connecting columns 36, which can facilitate the slider 37 to drive the clamping member 4 to move. The bearing plate 41 is installed at one end of the slider 37.
[0037] A camera 21 is installed on the top of the socket 2, and one end of the camera 21 extends to the interior of the socket 2. The camera 21 consists of an image sensor, an image processor, a lens module, a control circuit and a shell. It can focus light on the image sensor, convert the optical signal into an electrical signal, and feed it back to the image processor after signal processing and adjustment, and output the image signal through the control circuit. In this way, important parameters such as the plug-in status, position and angle of the charging gun can be obtained, and the charging gun plug-in test can be monitored and recorded. Basic data support is provided to provide more convenient and efficient application support for the realization of autofocus technology, data analysis and report output. At the same time, the degree of wear of the charging gun and the socket 2 after each plug-in and unplugging can be detected and recorded in real time.
[0038] During use, place the handle of the charging gun to be tested on the surface of the fixed seat 42, then rotate the screw 48 to make it rotate along the inside of the slide groove 412. At the same time, since it is threadedly connected to the movable seat 43 through the sliding block 432, when the screw 48 rotates, it will drive the movable seat 43 to slowly move toward the fixed seat 42 through the sliding block 432. At the same time, the sliding block 432 descends along the inside of the slide groove 412 and the T-block 431 descends along the inside of the T-slot 411 until the positioning block 46 at the bottom of the movable seat 43 is completely immersed in the positioning groove 47 on the surface of the fixed seat 42. At the same time, since the clamping member 4 is set at an angle, it is convenient to fix the charging gun.
[0039] In addition, the provision of the rubber strip 45 and the rubber ball 44 can increase the friction coefficient between the fixed base 42, the movable base 43 and the charging gun, thereby improving the stability and reliability of the clamping. While ensuring the clamping force, it effectively prevents the charging gun from shaking or tilting during the test, further ensuring the accuracy of the focus without the need for manual visual inspection.
[0040] When the charging gun is fixed, the stepping motor 34 is directly started to drive the screw rod 32 to rotate, so that the slider 37 drives the clamping member 4 to move toward the socket 2.
[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
