Description

Technical Field

[0001] The present invention relates to the technical field of charging pile detection, and in particular to a charging pile detection device. Background Art

[0002] Charging piles refer to charging devices that are designed to provide electric energy for electric vehicles. They have multiple protection functions, the ability to monitor and judge the charging status in real time, and can automatically adjust charging parameters according to the battery status and charging needs of the electric vehicle, realizing multiple charging modes such as constant current, constant voltage, and constant power. According to the power supply method, they can be divided into AC charging piles and DC charging piles, and the installation methods include vertical and wall-mounted.

[0003] After searching, the Chinese patent with the publication number CN118671490A discloses a vehicle charging pile detection device, which includes a charging pile detection body, and also includes: a support seat, which is movable, and the top surface of the support seat is provided with two slide grooves with a vertical section of ┴, the length of the slide groove is less than the length of the support seat, and one end surface of the slide groove is flush with the end surface of the support seat, and a fixed block with a vertical section of ┴ is inserted in the slide groove; two groups of adjustment components, the two groups of adjustment components correspond to two fixed blocks, and the adjustment components include a forward and reverse motor arranged on the fixed block, and four first gears rotating on the fixed block, the four first gears are meshed in sequence, and support columns are arranged on the first gears on both sides; a storage box, the storage box is placed on the top of the four support columns. By setting the slide groove, the slider, and the fixed block, the support seat and the fixed block can be quickly disassembled and installed, and the volume is small after disassembly, which is conducive to the movement of the vehicle charging pile detection device.

[0017] Beneficial effects of the present invention:

[0018] 1. This charging pile detection device, by setting a pulling component and a linkage component, the use of the pull rod allows the user to easily adjust its length and angle according to actual needs. By pulling the pull rod out of the rotating cylinder and fixing it through the bayonet with a clamp, the stability and comfort of the mobile base are ensured.

[0019] 2. This charging pile detection device, by setting a bracket and a brake assembly, through the cooperation of wedge block 1 and wedge block 2, and the sliding of the transmission shaft, enables the friction plate to apply pressure to the friction disc to generate a strong braking force. The convex strips on the friction disc increase the friction between the two, ensuring that the base can stop quickly and firmly, and even on a slope, it can ensure that the base will not continue to slide, thereby improving the safety of operation.

[0020] 3. This charging pile detection device, by setting up a mounting frame and a support assembly, when the base needs to be fixed, the support plate will change from a horizontal state to a vertical state, lifting the universal wheel, and at the same time, the support plate at the bottom of the support plate is in contact with the ground, providing a stable support point, greatly enhancing the stability of the base, which not only helps to prevent the base from accidentally moving, but also provides more stable support for operations such as plugging and unplugging the charging gun, thereby improving the convenience and safety of use.

[0035] like Figures 1 to 9 As shown, a charging pile detection device comprises a base 1 and a detection box 2, the detection box 2 is arranged on the top surface of the base 1, a display panel 3 is arranged on the side of the detection box 2, a plurality of detection sockets 4 are arranged on the side of the detection box 2, a shaft 5 is rotatably installed on one side of the bottom surface of the base 1, support wheels 6 are fixedly installed on both ends of the shaft 5, universal wheels 7 are symmetrically arranged on the other side of the bottom surface of the base 1, a pulling component is arranged at the pulling end of the base 1, and a linkage component corresponding to the pulling component is arranged at the pulling end of the base 1, a bracket 11 is symmetrically fixedly installed on the bottom surface of the base 1, a brake component adapted to the shaft 5 is arranged on the inner side of the bracket 11, a mounting frame 13 is symmetrically fixedly installed at the position between the two universal wheels 7 on the bottom surface of the base 1, a supporting component is arranged on the inner side of the mounting frame 13, and a positioning component is arranged between the pulling component and the linkage component;

[0036] When in use, the base 1 and the detection box 2 can be moved by pulling the assembly and the handle 9, so that the detection box 2 is moved to the position of the charging pile through the support wheels 6 and the universal wheels 7. The charging gun on the charging pile is unplugged and inserted into the corresponding detection socket 4 and the detection box 2 is turned on to detect the operating status of the charging pile, which can be displayed on the display panel 3. When the base 1 is pulled to the position of the charging pile or encounters ups and downs during the movement and the detection box 2 loses control due to its heavy weight and needs to stop the base 1 urgently, the staff can drive the linkage assembly to operate by pulling the assembly, so as to fix the base 1 by the brake assembly and the support assembly, ensuring the fixed state of the base 1 and the detection box 2 when the charging gun is plugged in and out and an emergency stop is required, making it more convenient to use, and the positioning assembly between the pulling assembly and the linkage assembly ensures the stability of the pulling assembly during normal use.

[0037] like Figures 1 to 5As shown, the pulling assembly includes a fixed frame 81 fixedly mounted on the pulling end of the base 1, a rotating shaft 82 rotatably mounted on the inner wall of the fixed frame 81, and a rotating cylinder 83 sleeved on the rotating shaft 82, one end of the rotating shaft 82 passes through the fixed frame 81 and is sleeved with a torsion spring 84, a pull rod 85 is slidably mounted on the inner wall of the rotating cylinder 83, a handle 9 is symmetrically fixedly mounted on the top of the pull rod 85, a spring 86 is arranged between the bottom end of the pull rod 85 and the inner bottom surface of the rotating cylinder 83, and a limiting mechanism is arranged between the rotating cylinder 83 and the pull rod 85;

[0038] like Figure 3 , Figure 4 As shown, the limiting mechanism includes a slot 87 provided at the bottom end of the pull rod 85, a clamping head 88 slidably mounted on the inner wall of the slot 87, and a spring 89 provided between the inner wall of the slot 87 and the clamping head 88. A clamping mouth 810 adapted to the clamping head 88 is provided at the top of the rotating cylinder 83, a guide opening 811 is provided on the side of the rotating cylinder 83, a connecting plate 812 is slidably mounted on the inner wall of the guide opening 811, and the side of the connecting plate 812 is fixedly connected to the bottom end of the pull rod 85.

[0039] When the base 1 and the detection box 2 are pulled, the pull rod 85 can be pulled out of the rotating cylinder 83. At this time, the clamping head 88 can pass through the bayonet 810 on the rotating cylinder 83 to fix the position of the pull rod 85, and then the rotating cylinder 83 is rotated and adjusted to the pulling angle through the rotating shaft 82, and the handle 9 can be pulled to move the base 1. When the plug-in charging gun and the base 1 need to stop urgently when going up or down a slope, the handle 9 can be released. At this time, the rotating shaft 82 and the rotating cylinder 83 can be rotated in the opposite direction under the action of the torsion spring 84, so that the rotating cylinder 83 is rotated to a state of being fitted with the linkage assembly. When the rotating cylinder 83 is fitted with the linkage assembly, the clamping head 88 can be pressed so that the clamping head 88 slides into the slot 87 and separates from the bayonet 810 on the rotating cylinder 83. At this time, under the action of the spring 1 86, the pull rod 85 can slide into the rotating cylinder 83 and drive the connecting plate 812 to slide along the guide opening 811.

[0040] like Figure 2 , Figure 6 As shown, the linkage assembly includes a fixed frame 101 fixedly installed on the pulling end of the base 1 corresponding to the fixed frame 81, a fixed rod 102 fixedly installed on the upper inner wall of the fixed frame 101 corresponding to the clamp 88, and a slide bar 103 penetrating the top surface of the base 1, a pressing plate 104 adapted to the connecting plate 812 is slidably installed on the inner wall of the fixed frame 101, and the bottom surface of the pressing plate 104 is fixedly connected to the top of the slide bar 103, a wedge 105 is fixedly installed on the bottom end of the slide bar 103, and a spring 3 106 is sleeved on the outer wall of the slide bar 103 located on the upper side of the base 1;

[0041] When the rotating cylinder 83 is fitted with the fixed frame 101, the fixed rod 102 in the fixed frame 101 can press the clamping head 88 so that the clamping head 88 slides into the slot 87, and the connecting plate 812 can press the pressure plate 104 in the fixed frame 101 during the sliding process. When the pressure plate 104 is pressed, it can drive the sliding rod 103 and the wedge block 105 to slide downward.

[0042] like Figure 2 , Figure 6 As shown, the brake assembly includes a transmission shaft 121 slidably mounted on the inner wall of the bracket 11, a friction plate 122 fixedly mounted on the end of the transmission shaft 121, and a friction disc 123 sleeved on the shaft 5, the outer wall of the friction disc 123 is provided with a plurality of convex strips 124 distributed in a ring array, the friction plate 122 is arranged in an arc shape adapted to the friction disc 123, a wedge block 2 125 corresponding to the wedge block 105 is fixedly mounted on one end of the transmission shaft 121 away from the friction plate 122, a spring 4 126 is sleeved on the transmission shaft 121, and the two ends of the spring 4 126 are respectively fixedly connected to the bottom surface of the base 1 and the outer wall of the transmission shaft 121;

[0043] When the wedge block 105 and the wedge block 2 125 are used in cooperation, when the wedge block 105 slides downward, the wedge block 2 125 can slide in the horizontal direction and drive the transmission shaft 121 to slide along the bracket 11, so that the friction plate 122 at the end of the transmission shaft 121 can squeeze the friction disk 123 on the shaft rod 5, and the convex strip 124 on the friction disk 123 can increase the friction force between the friction disk 123 and the friction plate 122, ensuring that the base 1 stops faster and more firmly.

[0044] like Figures 6 to 8 As shown, the support assembly includes a roller 141 rotatably mounted on the inner wall of the mounting frame 13, a support rod 142 symmetrically fixedly mounted on the outer wall of the roller 141, and a support plate 143 fixedly mounted on one end of the two support rods 142 away from the roller 141. A transmission gear 144 is rotatably mounted on the side of the mounting frame 13, and the transmission gear 144 is fixedly connected to the end of the roller 141. A fixing plate 145 is fixedly mounted on the outer wall of the transmission shaft 121, and a driving rack 146 is fixedly mounted on the end of the fixing plate 145, and the driving rack 146 is meshed with the transmission gear 144. A connecting mechanism is provided on the support plate 143.

[0045] like Figure 7 As shown, the connection mechanism includes a mounting opening 147 symmetrically opened on the side of the support plate 143, a rotating wheel 148 rotatably mounted on the inner wall of the mounting opening 147, and a support plate 149 fixedly mounted on the bottom surface of the support plate 143 away from the rotating wheel 148;

[0046] During the sliding of the transmission shaft 121 along the bracket 11, the driving rack 146 can be driven to slide through the fixed plate 145, and the driving rack 146 can mesh with the transmission gear 144, thereby driving the transmission gear 144 and the roller 141 to rotate, and rotating the support rod 142 from a horizontal state to a vertical state, lifting the two universal wheels 7, and during the rotation of the support plate 143, the rotating wheel 148 in the mounting port 147 can first contact the ground, ensuring that the rotation of the support plate 143 is faster. At the same time, after the support plate 143 rotates to a horizontal state, the support plate 149 contacts the ground, ensuring the horizontality of the support plate 143, further increasing the stability of the base 1 and preventing the base 1 from moving.

[0047] like Figure 2 , Fig. 9 As shown, the positioning assembly includes an arc-shaped plate 151 fixedly mounted on the side of the fixed frame 101, an arc-shaped opening 152 opened on the side of the arc-shaped plate 151, and a clearance groove 153 opened on the side of the rotating cylinder 83. A sliding seat 154 is slidably mounted on the inner wall of the clearance groove 153. A spring 155 is arranged between the sliding seat 154 and the inner wall of the clearance groove 153. A connecting rod 156 is screwed to the end of the sliding seat 154, and the connecting rod 156 is located inside the arc-shaped opening 152. A limiting opening 157 corresponding to the connecting rod 156 is opened on the inner wall of the arc-shaped opening 152 away from the fixed frame 101.

[0048] When it is necessary to pull the base 1 again, the handle 9 can be directly pulled to rotate the rotating cylinder 83 to the inclined state, and then the pull rod 85 can be pulled out of the rotating cylinder 83 and fixed. In order to ensure the convenience of using the handle 9, the use of the connecting rod 156 can be selected according to the pulling road conditions. If there is no ups and downslope, the pull rod 85 can be used. When the rotating cylinder 83 rotates, the pull rod 85 slides along the arc-shaped opening 152 on the side of the arc plate 151. When the rotating cylinder 83 is rotated to the pulling angle, the connecting rod 156 can be located at the position of the limit opening 157. At this time, under the action of the give way groove 153, the sliding seat 154 and the spring five 155, the connecting rod 156 can slide to the limit opening 157 to fix the angle of the rotating cylinder 83. When the connecting rod 156 is not needed, the connecting rod 156 can be directly removed from the sliding seat 154, so that the handle 9 can be directly released to realize the emergency stop of the base 1.

[0049] The technical solution provided by the present invention can be used to move the base 1 and the detection box 2 by pulling the assembly and the handle 9, so that the detection box 2 can be moved to the position of the charging pile through the support wheels 6 and the universal wheels 7, and the charging gun on the charging pile can be unplugged and inserted into the corresponding detection socket 4 and the detection box 2 can be turned on to detect the operating status of the charging pile, which can be displayed on the display panel 3. When the base 1 is pulled to the position of the charging pile or encounters ups and downs during the movement, when the detection box 2 loses control due to its large dead weight and needs to stop the base 1 urgently, the staff can drive the linkage assembly to operate by the pulling assembly, so as to fix the base 1 by the brake assembly and the supporting assembly, ensuring the fixed state of the base 1 and the detection box 2 when the charging gun is plugged in and out and the emergency stop is required, making it more convenient to use, and the positioning assembly between the pulling assembly and the linkage assembly ensures the stability of the pulling assembly during normal use. The working principle and connection method of the detection box 2, the display panel 3 and the detection socket 4 are all existing mature technologies, which will not be described in detail here.

[0050] Specifically, when the base 1 and the detection box 2 are pulled, the pull rod 85 can be pulled out of the rotating cylinder 83. At this time, the clamping head 88 can pass through the bayonet 810 on the rotating cylinder 83 to fix the position of the pull rod 85, and then the rotating cylinder 83 is rotated and adjusted to the pulling angle through the rotating shaft 82, and the handle 9 can be pulled to move the base 1. When the plug-in charging gun and the base 1 needs to be stopped urgently when going up and down slopes, the handle 9 can be released. At this time, the rotating shaft 82 and the rotating cylinder 83 can be rotated in the opposite direction under the action of the torsion spring 84, so that the rotating cylinder 83 is rotated to a state of being in contact with the fixed frame 101. When the rotating cylinder 83 is in contact with the fixed frame 101, the fixed rod 102 in the fixed frame 101 can press the clamping head 88 so that the clamping head 88 slides into the slot 87 and separates from the bayonet 810 on the rotating cylinder 83. When the connecting plate 812 slides, the pressure plate 104 in the fixed frame 101 can be pressed, and the pressure plate 104 can drive the sliding rod 103 and the wedge block 105 to slide downward. When the wedge block 105 and the wedge block 2 125 are used together, the wedge block 105 can slide in the horizontal direction when the wedge block 105 slides downward, and drive the transmission shaft 121 to slide along the bracket 11, so that the friction plate 122 at the end of the transmission shaft 121 can squeeze the friction disk 123 on the shaft rod 5, and the convex strip 124 on the friction disk 123 can increase the friction between the friction disk 123 and the friction plate 122, ensuring that the base 1 stops more quickly and firmly.

[0051] At the same time, during the sliding of the transmission shaft 121 along the bracket 11, the driving rack 146 can be driven to slide through the fixing plate 145, and the driving rack 146 can mesh with the transmission gear 144, thereby driving the transmission gear 144 and the roller 141 to rotate, and rotating the support rod 142 from the horizontal state to the vertical state, lifting the two universal wheels 7, and during the rotation of the support plate 143, the rotating wheel 148 in the mounting opening 147 can first contact the ground, ensuring that the rotation of the support plate 143 is faster. At the same time, after the support plate 143 rotates to the horizontal state, the support plate 149 contacts the ground to ensure the horizontality of the support plate 143, further increasing the stability of the base 1 and preventing the base 1 from moving; and when it is necessary to pull the base 1 again, the handle 9 can be directly pulled to make the rotating cylinder 83 rotate to the inclined state, the connecting plate 812 is separated from the pressure plate 104, and the sliding rod 103 and the wedge block are pulled under the action of the spring three 106. 154 and 155, and the connecting rod 156 can be located at the position of the limit opening 157. At this time, under the action of the makeshift groove 153, the sliding seat 154 and the spring five 155, the connecting rod 156 can slide into the limit opening 157 to fix the angle of the rotating cylinder 83. When the connecting rod 156 is not needed, the connecting rod 156 can be directly removed from the sliding seat 154, so as to directly release the handle 9 to realize the emergency stop of the base 1.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
