[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0039] Please see Figures 1 to 3 This embodiment provides a fixing device 100 for a charging device 200. The fixing device 100 is used for charging the charging device 200 and for locking and fixing the charging device 200 during the charging process. The fixing device 100 may include a base plate 110, supports 120, a pressure rod 130, and a locking assembly 140. The base plate 110 may be rectangular in shape. Two supports 120 are spaced apart on the base plate 110. Specifically, the two supports 120 may be located at the edge of the top surface of the base plate 110 and arranged along the length of the base plate 110. At the same time, the distance between the opposite end faces of the two supports 120 may be equal to or slightly greater than the width of the charging device 200 to limit and fix the left and right sides of the charging device 200. The two ends of the pressure rod 130 are rotatably connected to the two supports 120 respectively. Furthermore, a locking pin 131 is provided on the surface of the pressure rod 130 near the support 120. The locking pin 131 is used to lock and fix the charging device 200 after the pressure rod 130 has fixed it.

[0040] The locking assembly 140 is disposed on the support 120, and includes a connector 141 with a side stop 1411, a guide post 142, a locking hook 143, and an elastic member 144. The connector 141 is mounted on the support 120. The two ends of the guide post 142 are respectively connected to the side stop 1411 and the locking hook 143. The elastic member 144 is sleeved on the guide post 142 and its two ends abut against the surfaces of the side stop 1411 and the locking hook 143. When the pressure rod 130 is rotated to fix the charging device 200, the locking hook 143 can cooperate with the locking pin 131 to lock the pressure rod 130.

[0041] With this configuration, the base plate 110 and the supports 120 spaced apart on the base plate 110 define a accommodating area for the charging device 200, thus limiting the left and right directions of the charging device 200. Through the setting of the pressure rod 130 and the locking component 140, when the charging device 200 is placed on the base plate 110 for charging, pressing the pressure rod 130 not only limits and fixes the charging device 200, but also allows the locking hook 143 of the locking component 140 to cooperate with the locking pin 131 to lock the pressure rod 130. On the one hand, the placement and locking of the charging device 200 and the charging connection are performed simultaneously; on the other hand, the charging device 200 is securely locked, improving the stability of the charging process. Furthermore, when the charging device 200 is finished charging and needs to be removed, pressing the connector 141 of the locking component 140 unlocks the pressure rod 130. The operation is convenient and comfortable, with a high degree of human-machine integration.

[0042] Optionally, the four corners of the base plate 110 can be rounded, and multiple screw holes can be provided on the surface of the base plate 110 to facilitate the installation of the fixing device 100 on other structures or equipment. The two supports 120 are mirror images and can have the same structure. The supports 120 can be fixedly installed on the base plate 110 by means of bolts or welding. The two locking components 140 provided on the supports 120 can also be mirror images and have the same structure. This arrangement facilitates the installation of the fixing device 100 and simplifies the structure of the fixing device 100.

[0043] In some embodiments, please refer to Figure 4 The support 120 is provided with a rotating shaft 121 rotatably connected to the pressure rod 130. A torsion spring 123 is sleeved on the rotating shaft 121. One end of the torsion spring 123 is connected to the support 120, and the other end abuts against the pressure rod 130. The torsion spring 123 is configured to drive the pressure rod 130 to rotate around the rotating shaft 121 to its initial position when the locking hook 143 releases its lock on the pressure rod 130. Specifically, a first limiting groove 122 can be provided on the surface of the support 120 near the rotating shaft 121. The shape of 130 can be selectively set according to the shape of the charging device 200. Through holes 132 can be opened at both ends of the pressure rod 130, and the pressure rod 130 and the support 120 can be rotated by inserting the rotating shaft 121 into the through holes 132. At the same time, a second limiting groove 133 communicating with the through holes 132 is opened on the surface of the pressure rod 130 and the support 120. The two ends of the torsion spring 123 extend into the first limiting groove 122 and the second limiting groove 133, respectively.

[0044] With this configuration, the torsion spring 123 does not accumulate elastic potential energy in its natural state. When the pressure rod 130 rotates and presses down to fix the charging device 200, the torsion spring 123 will accumulate elastic potential energy. When the locking component 140 unlocks the pressure rod 130, the pressure rod 130 will be affected by the elastic force of the torsion spring 123 and automatically spring open, thus facilitating the removal of the charging device 200 from the fixing device 100.

[0045] Optional, please continue reading Figure 4 The locking pin 131 can be fixed to the two outer end faces of the pressure rod 130 by screws or bolts. The pressure rod 130 can be provided with multiple bends 134. At least one protrusion 135 is provided on the surface of the pressure rod 130 between two bends 134. When the pressure rod 130 is in the locked state, at least part of the surface of the protrusion 135 abuts against the charging device 200. Specifically, a corresponding groove can be provided on the charging device 200. When the charging device 200 is locked, the protrusion 135 cooperates with the groove, thereby improving the stability after locking.

[0046] In some embodiments, please refer to Figure 5 The locking hook 143 has a groove 1431 arranged along the axis of the guide post 142 on its side end face. The connector 141 is provided with at least one slider 1412 extending into the groove 1431. Specifically, the groove 1431 is a through groove. Two sliders 1412 are spaced apart and pass through the groove 1431 to connect to the stop block 1413. With this arrangement, when the locking hook 143 is slid, the groove 1431 and the slider 1412 ensure the stability of the sliding process of the locking hook 143.

[0047] Optionally, the locking hook 143 has a locking groove 1432 near the top of the slide groove 1431. When the locking hook 143 locks the pressure rod 130, the locking pin 131 extends at least partially into the locking groove 1432. It should be noted that a guide slope can also be provided on the top surface of the locking groove 1432. That is, when the pressure rod 130 is pressed down to fix the charging device 200, the locking pin 131 first abuts against the top surface of the locking groove 1432. By providing the guide slope, the locking pin 131 can provide a sliding force to the locking hook 143 along the guide post 142, thereby causing the locking hook 143 to compress the elastic member 144. The elastic member 144 accumulates elastic potential energy. At the same time, the locking pin 131 slides into the locking groove 1432 to lock and fix the pressure rod 130.

[0048] Of course, it is understandable that when unlocking is required, simply move the locking hook 143 toward the compression elastic member 144, thereby disengaging the locking pin 131 from the locking groove 1432 to complete the unlocking. Meanwhile, the elastic member 144 can be a structure made of spring or other elastic material, depending on the actual needs.

[0049] Optionally, one end of the guide post 142 is fixedly connected to the side stop 1411, and the other end is slidably connected to the locking hook 143. In this case, the locking hook 143 can slide along the guide post 142 relative to the connector 141 and can compress the elastic member 144. Alternatively, one end of the guide post 142 is slidably connected to the side stop 1411, and the other end is fixedly connected to the locking hook 143. In this case, the locking hook 143 and the guide post 142 slide simultaneously and can compress the elastic member 144. That is, both connection methods can realize the sliding of the locking hook 143 and the compression of the elastic member 144.

[0050] In some embodiments, please refer to Figure 6 At least one pad 150 is provided on the base plate 110. The pad 150 is arranged along the length of the base plate 110 and is located between the two supports 120. For example, the two pads 150 are arranged in parallel on the upper surface of the base plate 110. The shape of the pad 150 can be strip-shaped. The pad 150 can be fixedly connected to the base plate 110 by bolts. The pad 150 is made of nylon material and the upper surface is smooth.

[0051] With this design, the charging device 200 experiences less resistance when sliding above the base plate 110, making it easier to pick up and put down, and also reducing the risk of wear on the paint surface at the bottom of the device casing.

[0052] In some embodiments, please refer to Figures 6 to 8 The fixing device 100 also includes a back plate 160, which is connected to the surface of the base plate 110 near the support 120. The surface of the back plate 160 facing the receiving area is provided with a charging plug 161 and at least one positioning pin 162 near the charging plug 161. For example, the charging plug 161 can be fixedly installed on the back plate 160 by bolts. The two positioning pins 162 are respectively provided on the surface areas of the back plate 160 near the charging plug 161 on both sides. The positioning pins 162 can be fixed on the back plate 160 by bolts. It should be understood that three or four positioning pins 162 can also be provided, which can be selected according to actual needs.

[0053] It should be noted that the head of the positioning pin 162 can be tapered and can cooperate with the positioning hole 220 at the tail of the charging device 200 to automatically guide the charging device 200 to a fixed position. The two sides of the shoulder of the positioning pin 162 that contact the mounting surface of the back plate 160 are flat, which makes it easy to clamp with tools when using fasteners and prevents slippage.

[0054] With this setup, the charging device 200 needs to be placed on the fixed device 100 during the charging process. The positioning pin 162 enables the charging device 200 to be automatically aligned. At the same time, it ensures that the charging port 210 of the charging device 200 accurately matches the charging plug 161 to complete the electrical connection.

[0055] In some embodiments, continue reading Figure 7 A cushioning pad 163 is provided on the surface of the back panel 160 near the charging plug 161. The cushioning pad 163 can be rectangular and is provided on the surface area of ​​the back panel 160 below the charging plug 161. The cushioning pad 163 can be installed on the back panel 160 by a locking plate 164. The cushioning pad 163 can be made of a highly elastic material.

[0056] With this configuration, when the charging device 200 is fixed, the buffer pad 163 can provide sufficient elasticity to eliminate the gaps in the fit during the pressing of the charging device 200 by the pressure plate, so that the charging device 200 is locked firmly and will not generate noise or fail due to vibration during the charging process.

[0057] In some embodiments, please refer to Figure 8 The charging device 200 has recessed handles 230 on both sides of its main body, which makes it easy to pick up the charging device 200 without affecting the overall appearance and size of the device. The unlocking end of the fixing device 100 is designed behind the handles on both sides of the charging device 200. At the same time, the pressure rod 130 in this area has an upwardly curved part 134 to avoid the recessed handles 230 on both sides of the main body. This design makes it easy to pick up the charging device 200 without affecting the overall appearance and size of the device. The charging device 200 can be pressed to unlock while picking it up, making the operation convenient and comfortable with a high degree of human-machine integration. Of course, a handle is set in the middle of the top surface of the charging device 200, which facilitates the handling of the charging device 200.
