DETAILED DESCRIPTION

[0021] The following is combined with Figures 1 to 4 The utility model is described in detail.

[0022] The utility model is a charging gun plugging and unplugging force testing device, comprising a fixed platform 1, a driving mechanism 2, a discharge seat 3 and a plugging and unplugging force detection mechanism 4; the plugging and unplugging force detection mechanism 4 is arranged on the fixed platform 1, and the plugging and unplugging force detection mechanism 4 at least comprises a fixed gun seat 41 and a plugging and unplugging force sensor 42 for detecting the plugging and unplugging force of the charging gun; the discharge seat 3 is provided with a receiving position 31 for placing the charging gun; the driving mechanism 2 is installed on the fixed platform 1, and the driving mechanism 2 drives the discharge seat 3 to move relative to the fixed gun seat 41. The operating principle of the utility model is as follows: first, the charging gun is placed on the discharge seat 3 and fixed, and then the driving mechanism 2 drives the plugging end of the charging gun to move toward the fixed gun seat 41 of the plug-in force detection mechanism 4, so that the charging gun and the fixed gun seat 41 are moved and plugged. At this time, the plug-in force sensor 42 records the plugging force of the charging gun. When the driving mechanism 2 drives the discharge seat 3 to move in the opposite direction, the charging gun is pulled out of the fixed gun seat 41. Similarly, the plug-in force sensor 42 records the pull-out force at this time. The recorded plug-in force and pull-out force are used to assist in evaluating the performance and service life of the charging gun.

[0023] Compared with the traditional charging gun plugging and extraction force testing device, the utility model has a simple overall structure, low manufacturing cost, does not take up too much space, is more convenient to use, and better meets production needs.

[0024] As an embodiment, the insertion force detection mechanism 4 further includes a mounting frame 43 , which serves as a supporting medium. The mounting frame 43 is fixedly connected to the fixed platform 1 , and the fixed gun seat 41 and the insertion force sensor 42 are both mounted on the mounting frame 43 .

[0025] As another embodiment, the insertion and extraction force detection mechanism 4 also includes an adjusting cylinder 44, which is arranged on the mounting frame 43, and the adjusting cylinder 44 can drive the fixed gun seat 41 to move relative to the discharge seat 3, so that the front and rear positions of the fixed gun seat 41 are adjustable, and the position of the fixed gun seat 41 can be changed according to actual testing requirements, thereby making the application scope of the utility model wider.

[0026] Preferably, the insertion and extraction force detection mechanism 4 further includes a movable frame 45, the movable frame 45 is telescopically connected to the mounting frame 43, the fixed gun seat 41 is arranged at the front end of the movable frame 45, and the adjusting cylinder 44 drives the movable frame 45 to move. The movable frame 45 is provided with a plurality of guide rollers and is telescopically connected to the mounting frame 43 through the guide rollers, so that the fixed gun seat 41 can move more stably under the drive of the adjusting cylinder 44.

[0027] In the utility model, the driving mechanism 2 includes a linear module 21 and a driving motor 22, the discharge seat 3 is slidably connected to the linear module 21, and the driving motor 22 drives the discharge seat 3 to reciprocate along the linear module 21 to perform the plugging and unplugging action between the tested gun body and the fixed gun seat 41.

[0028] Preferably, the material discharging seat 3 is provided with a quick fixing clamp 32 for quickly fixing the charging gun. After placing the gun body, the quick fixing clamp 32 can be bent upward to quickly realize the positioning and fixing of the gun body to be tested.

[0029] Preferably, the discharge seat 3 is also provided with a button mechanism 5 for pressing the button of the charging gun. Under normal circumstances, when the charging gun is plugged into or unplugged from the charging seat of a new energy vehicle, it is necessary to press the charging button of the charging gun first. For this reason, the inventor sets a button mechanism 5 to replace manual pressing of the button, so that the detection device has a higher degree of automation, is more convenient to use, and the detection efficiency can also be improved. Secondly, the button mechanism 5 can be used in conjunction with the plug-in and pull-out force detection device to compare the plug-in and pull-out force data of the charging gun when the button is pressed or not, so as to more accurately evaluate the performance of the charging gun.

[0030] In this technical solution, if Figure 3 and 4 As shown, the button mechanism 5 includes a rotating cylinder 51, a rotating block 52 and a pressing cylinder 53 connected in sequence. The rotating cylinder 51 drives the rotating block 52 to rotate, and the rotating block 52 drives the pressing cylinder 53 to move above the discharge seat 3 and align with the charging button of the charging gun. When the pressing cylinder 53 is started, the charging gun button can be directly pressed. The button mechanism 5 has a simple overall structure and a high degree of automation.

[0031] Since the button of the charging gun is set on a curved surface, in order to adapt to the structure of the charging gun, the button mechanism 5 also includes a tilting platform 54, and the rotating cylinder 51 is set on the top of the tilting platform 54, so that the rotating cylinder 51 is tilted, so that the pressing cylinder 53 is also tilted, which is convenient for pressing the button and can better simulate the scene of pressing the charging gun button; it can also avoid the button mechanism 5 from colliding with the quick fixing clip 32.

For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
