Description

Technical Field

[0001] The present application relates to the field of chargers, and in particular to an insertion force detection device. Background Art

[0002] With the development of electric vehicles, electric vehicle charging guns are becoming more and more popular. Currently, when connecting the charging gun to the charging seat, the charging gun is generally inserted into the charging seat. However, since the charging gun and the charging seat are tightly fitted, the charging gun needs to be pushed hard when inserted into the charging seat, so the charging seat will bear the pushing force. In order to prevent the charging seat from falling off when the charging gun is inserted, the insertion force of the charging gun needs to be tested.

This solution can provide power to the mounting plate by providing a hydraulic rod, so that the mounting plate can control the charging seat to move downward. The charging gun plug can be supported by a support plate. With the elastic force of the spring, the push plate can position the charging gun plug to prevent the charging gun plug from loosening during use. When the charging seat moves downward, pressure can be applied to the charging gun plug. With the pressure sensor and pressure display, the insertion force of the charging gun plug when inserted into the charging seat can be displayed, thereby solving the problem of manually inserting the charging gun into the charging seat for testing, and it is difficult to accurately obtain the charging gun insertion force during the test.

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0029] like Figure 1-5 As shown, the present application provides an insertion force detection device, including a bracket 1, a hydraulic rod 2 is installed at the top of the bracket 1, a mounting block 3 is fixedly connected to the output end of the hydraulic rod 2, a base 4 is arranged on the lower side of the mounting block 3, a charging seat 5 is installed at the bottom end of the base 4, and a pair of limiting columns 6 are fixedly connected to the top of the base 4, the limiting columns 6 are slidably connected to the mounting block 3, a pressure sensor 7 is installed at the top of the base 4, a mounting column 8 is fixedly connected to the bottom end of the inner wall of the bracket 1, a bearing tray 9 is fixedly connected to the upper end of the mounting column 8, the axis of the bearing tray 9 and the charging seat 5 are in the same vertical position, and a plurality of first limiting holes 10 distributed in a cross shape are opened on the bearing tray 9, and a plurality of sliding blocks 14 distributed in a cross shape are arranged on the upper side of the bearing tray 9, A clamping block 15 is slidably connected to the slider 14, and a positioning rod 16 is fixedly connected to the bottom end of the slider 14. The positioning rod 16 passes through the first limiting hole 10. The outer end of the mounting column 8 is rotatably connected to a rotating disk 11. The rotating disk 11 is arranged on the lower side of the supporting tray 9, and a plurality of second limiting holes 12 arranged in a ring shape and equidistant are opened on the rotating disk 11. The plurality of second limiting holes 12 are all inclinedly arranged, and the plurality of positioning rods 16 respectively pass through the plurality of second limiting holes 12. A gear ring 13 is fixedly connected to the outer end of the rotating disk 11. A servo motor 19 is installed on the bracket 1. A gear 20 is fixedly connected to the output end of the servo motor 19. The gear 20 is meshed with the gear ring 13. A plurality of clamping blocks 15 are slidably connected to one end close to each other with a movable block 18.

[0030] With the development of electric vehicles, electric vehicle charging guns are becoming more and more popular. Currently, when connecting the charging gun to the charging seat, the charging gun is generally inserted into the charging seat. However, since the charging gun and the charging seat are tightly fitted, the charging gun needs to be pushed hard when inserted into the charging seat, so the charging seat will bear the pushing force. In order to prevent the charging seat from falling off when the charging gun is inserted, the insertion force of the charging gun needs to be tested.

[0031] In this solution, during the detection process, the user first places the charging gun plug on the top of the tray 9 so that the plug is located between the multiple clamping blocks 15, and then starts the servo motor 19 to drive the gear 20 to rotate. The gear 20 can drive the ring gear 13 to rotate, thereby forcing the rotating disk 11 to rotate. During the rotation of the rotating disk 11, the positioning rod 16 will be forced to move in the first limiting hole 10 and the second limiting hole 12, and the positioning rod 16 drives the slider 14 to move, thereby causing the multiple sliders 14 to slide towards each other at the top of the tray 9, and the multiple clamping blocks 15 are driven to move by the multiple sliders 14, and the multiple clamping blocks 15 drive the multiple movable blocks 18 to move, and then the plug is clamped by the multiple movable blocks 18 to achieve the purpose of fixing the plug.

[0032] like Figure 6 As shown, a spring 17 is sleeved on the outer end of the clamping block 15 , and two ends of the spring 17 are fixedly connected to the clamping block 15 and the slider 14 respectively.

[0033] The main standard adopted by domestic new energy vehicles is GB / T, but the appearance of the charging gun plugs used by different car companies and different models of new energy vehicles is not the same. The base of the plug may be a cylinder, a cube or a rectangular block, so this solution needs to ensure that the plug is fixed at the center position of the top of the tray 9 to ensure that the plug can be aligned with the charging seat 5 located directly above the center point of the tray 9. For the cylindrical and cubic charging gun bases, since the diameter of the cylinder remains unchanged and the four sides of the cube are equal in width, multiple clamping blocks 15 can easily push the plug to the center of the tray 9 and then fix it during the synchronous approach process. For the rectangular base, its two short sides must first abut against a pair of clamping blocks 15. At this time, a pair of positioning rods 16 abut against the plug base to temporarily fix the plug, and the multiple sliders 14 can continue to move closer, and the clamping block 15 that has abutted against the plug base remains stationary. The spring 17 at the outer end of the clamping block 15 is stretched. When the positioning rods 16 located on both sides of the long side of the plug base abut against the plug base, the plug will be pushed to move toward the center position of the tray 9. Although the short side of the plug base has been clamped by another pair of clamping blocks 15 at this time, the plug base can still move through the sliding connection between the positioning rods 16 and the clamping blocks 15. Therefore, when the multiple clamping blocks 15 stop moving, even if it is a rectangular plug base, it can still be stably fixed in the center position above the tray 9.

[0034] After the charger plug is fixed, the user starts the hydraulic rod 2 to drive the mounting block 3 to move downward, and drives the base 4 and the charging seat 5 to move downward through the mounting block 3, so that the charging seat 5 is docked with the charger plug. During the docking process, the base 4 moves upward under pressure, driving a pair of limit columns 6 to slide on the mounting block 3 and squeeze the pressure sensor 7, so that the pressure sensor 7 can detect the pressure on the charging seat 5. The user connects the pressure sensor 7 to the computer to obtain the value of the insertion force.

[0035] Anti-skid pads are installed on the ends of the plurality of movable blocks 18 close to each other.

[0036] The provision of the anti-slip pad can enhance the friction between the positioning rod 16 and the charger plug, thereby improving the stability of the plug clamping.

[0037] Working principle:

[0038] During use, the user first places the charging gun plug on the top of the tray 9 so that the plug is located between the multiple clamping blocks 15, and then starts the servo motor 19 to drive the gear 20 to rotate. The gear 20 can drive the ring gear 13 to rotate, thereby forcing the rotating disk 11 to rotate. During the rotation of the rotating disk 11, the positioning rod 16 will be forced to move in the first limiting hole 10 and the second limiting hole 12, and the positioning rod 16 drives the slider 14 to move, so that the multiple sliders 14 slide in the direction of approaching each other at the top of the tray 9, and the multiple clamping blocks 15 are driven to move by the multiple sliders 14, and the multiple clamping blocks 15 drive the multiple movable blocks 18 to move, and then the plug is clamped by the multiple movable blocks 18. For the cylindrical and cubic charging gun bases, the multiple clamping blocks 15 can easily push the plug to the center of the tray 9 and then fix it during the synchronous approach process. For the rectangular base, one pair of positioning rods 16 will first abut against the short side of the plug base to temporarily fix the plug, and the multiple sliders 14 can continue to approach. The clamping block 15 that has been in contact with the plug base remains stationary, and the spring 17 at the outer end of the clamping block 15 is stretched. When the positioning rods 16 on both sides of the long side of the plug base are in contact with the plug base, the plug will be pushed to move to the center position of the tray 9. The plug base can be moved by the sliding connection between the positioning rods 16 and the clamping block 15. Therefore, when multiple clamping blocks 15 stop moving, even a rectangular plug base can still be stably fixed in the center position above the tray 9, so that the charging gun plug is aligned with the charging seat 5. After the charger plug is fixed, the user starts the hydraulic rod 2 to drive the mounting block 3 to move downward, and drives the base 4 and the charging seat 5 to move downward through the mounting block 3, so that the charging seat 5 is docked with the charger plug. During the docking process, the base 4 is pressed upward, driving a pair of limit columns 6 to slide on the mounting block 3 and squeezing the pressure sensor 7, so that the pressure sensor 7 can detect the pressure on the charging seat 5. The user connects the pressure sensor 7 to the computer to obtain the value of the insertion force.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
