Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to an explosion-proof new energy charging pile. Background Art

[0002] At present, the function of new energy electric vehicle charging piles is similar to that of gas pumps in gas stations. They can be fixed on the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels.

[0003] In the related art, a new energy charging pile is designed, which includes a cabinet and a panel. Components are arranged on the inner wall of the cabinet, and the panel is fixed on one side of the cabinet. When the components explode due to short circuit, high temperature and other reasons, the broken components will hit the panel and the cabinet inside the cabinet. Since the panel and the cabinet are fixed to each other, the interior of the charging pile is relatively sealed. The air pressure generated at the moment of the explosion can easily damage and explode the charging pile, and the broken components will also damage the panel after hitting the panel. The explosion-proof effect of the charging pile is poor, and the explosion of internal electronic components can easily cause damage to the charging pile. The safety is low, so it needs to be improved. Summary of the Invention

[0004] In order to improve the strength of the charging pile, reduce the damage to the panel when the internal electronic components explode, and enhance the safety of the charging pile, the present application provides an explosion-proof new energy charging pile.

[0005] The explosion-proof new energy charging pile provided in this application adopts the following technical solution:

[0006] An explosion-proof new energy charging pile comprises a cabinet and a panel, an opening is provided on one side of the cabinet, the panel is provided at the opening, the panel and the cabinet are connected to each other, and a number of connecting rods are provided between the panel and the cabinet, and a positioning plate is integrally provided at one end of the connecting rod facing the inner wall of the cabinet, and the positioning plate and the inner wall of the cabinet are connected to each other; a connecting plate is integrally provided at one end of the connecting rod facing the panel, and a guide rod is fixedly provided on the side wall of the connecting plate, and the panels are slidably arranged on the guide rod together; a buffer spring is sleeved on the guide rod, and an abutment block is connected to the guide rod, one end of the buffer spring abuts against the abutment block, and the other end of the buffer spring abuts against the panel, and the buffer spring drives the panel to simultaneously fit against the cabinet end wall and the surface of the connecting plate.

[0007] By adopting the above technical solution, when installing the charging pile, the positioning plate on one end of the connecting rod is first connected to the inner wall of the cabinet, so that the connecting rod is fixed on the inner wall of the cabinet, and then the panel is jointly sleeved on the guide rod. The panel slides on the guide rod until it is in contact with the end wall of the cabinet, and then the buffer spring is sleeved on the guide rod. Finally, the abutment block is fixed on the guide rod. The buffer spring drives the panel to simultaneously fit the end wall of the cabinet and the surface of the connecting plate to complete the installation of the cabinet. If the electronic components in the cabinet explode, the instantaneous air pressure will impact the panel. At this time, the panel can slide on the guide rod in the direction away from the cabinet, and the buffer spring is compressed under force. The buffer spring can cushion the impact on the panel. After the panel is instantly away from the cabinet, the air flow can also flow away from the panel and the cabinet. After the panel is subjected to force, it can abut against the abutment block. The abutment block prevents the panel from separating from the guide rod. The connecting rod is used to improve the strength of the charging pile, and the guide rod and the buffer spring are used to reduce the damage to the panel when the internal electronic components explode, thereby enhancing the safety of the charging pile.

[0008] Preferably, a buffer groove is formed on the side wall of the abutment block, and one end of the buffer spring away from the panel abuts against the bottom wall of the buffer groove, and the buffer spring can be completely retracted into the buffer groove.

[0009] By adopting the above technical solution, if the components inside the cabinet explode, the panel will receive the impact and slide toward the abutment block on the guide rod, and the buffer spring will contract. The buffer spring can be completely retracted into the buffer groove, making way for the buffer spring, so that the abutment block can contact the panel. The abutment block is used to increase the contact area with the panel, which can support and limit the panel and reduce the phenomenon of panel breakage.

[0010] Preferably, a card block is fixedly provided on the guide rod, the abutment block is sleeved on the guide rod, a through hole for the card block to pass through is provided on the bottom wall of the buffer groove, and a card slot for the card block to be inserted and abutted is also provided on the bottom wall of the buffer groove.

[0011] By adopting the above technical solution, after the buffer spring is sleeved on the guide rod, the abutment block is sleeved on the guide rod, and the abutment block slides on the guide rod. The card block is first passed through the through hole, and then the abutment block is rotated to align the card block and the card slot with each other. After the reset spring and the abutment block are abutted, the card block can be driven to abut against the inner wall of the card slot, thereby quickly connecting the card block to the guide rod, making it convenient to disassemble and assemble the card block and the guide rod, and thus facilitating the maintenance of the charging cabinet.

[0012] Preferably, a group of positioning screws are symmetrically arranged on the positioning plate, and the positioning screws pass through the positioning plate and the end wall of the cabinet. The two positioning screws on the positioning plate are commonly connected to a mounting plate, and a positioning nut is threadedly connected to the positioning screw. The positioning nut is against the surface of the positioning plate, and the mounting plate is against the outer wall of the cabinet.

[0013] By adopting the above technical solution, when installing the connecting rod, first the positioning nut on the mounting plate is passed through the cabinet body, and then the positioning plate is placed on the positioning screw, and finally the positioning nut is threadedly connected to the positioning screw. The positioning nut is abutted against the surface of the positioning plate, and the mounting plate is abutted against the outer wall of the cabinet body, so that the connecting rod is quickly fixed to the inner wall of the cabinet body. The positioning plate and the mounting plate increase the contact area between the connecting rod and the cabinet body, thereby improving the connection strength between the connecting rod and the cabinet body.

[0014] Preferably, reinforcing rods are provided between adjacent abutment blocks, and dovetail blocks are integrally provided at both ends of the reinforcing rods. Dovetail grooves for inserting the dovetail blocks are provided on the end walls of the abutment blocks, and the dovetail blocks and the dovetail grooves are adapted to each other.

[0015] By adopting the above technical solution, after the abutment block is fixed on the guide rod, the dovetail blocks at both ends of the reinforcing rod are inserted into the dovetail grooves on the adjacent abutment blocks, and the dovetail blocks are used to abut against the inner walls of the dovetail grooves to connect the reinforcing rods between the adjacent abutment blocks. The reinforcing rods can increase the connection strength between the adjacent guide rods. When the enclosure is hit and slides toward the abutment block, the reinforcing rods can also abut against the side walls of the enclosure. The reinforcing rods further limit and support the enclosure, thereby increasing the strength of the enclosure.

[0016] Preferably, a plurality of support rods are symmetrically fixedly provided at one end of the cabinet body in the opening direction, and the panels are slidably provided on the support rods.

[0017] By adopting the above technical solution, the enclosure slides together on the guide rod and the support rod. The support rod supports the enclosure, reducing the pressure received by the guide rod, improving the overall strength and helping to extend the service life.

[0018] Preferably, a mounting bracket is fixedly provided on the outer wall of the cabinet, a high-pressure tank for storing dry powder is provided on the mounting bracket, a nozzle opening is connected to the high-pressure tank, a sealing plug is threadedly connected to the nozzle opening, a mounting groove for the nozzle opening and the sealing plug to pass through is provided on the cabinet, a linkage assembly is provided between the panel and the sealing plug, and the linkage assembly is used to drive the sealing plug and the nozzle opening to rotate when the panel slides on the support rod away from the opening.

[0019] Preferably, the linkage assembly includes a rack and a gear, the gear is arranged on the outer wall of the sealing plug, the gear and the sealing plug are coaxially arranged, the gear can pass through the installation slot, the rack is fixedly arranged on the side of the panel facing the opening direction, and the rack and the gear are engaged with each other.

[0020] By adopting the above technical solution, when installing the high-pressure tank, the sealing plug and the nozzle mouth are passed through the installation groove to make the gear and the rack engage with each other. When the electronic components in the cabinet explode, the air pressure generated instantly will impact the panel. At this time, the panel can slide on the guide rod in the direction away from the cabinet, and the rack slides with the enclosure. The rack and the gear are against each other, driving the gear and the sealing plug to rotate. After the sealing plug rotates, it will be separated from the nozzle mouth. Due to the high air pressure in the high-pressure tank, the dry powder in the high-pressure tank will be instantly sprayed out through the nozzle mouth the moment the sealing plug is separated from the nozzle mouth, and the dry powder is used to extinguish the fire in the charging cabinet, thereby reducing the phenomenon of continuous explosion of the charging cabinet and improving the safety of the charging pile.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By arranging the cabinet, panel, opening, connecting rod, positioning plate, connecting plate, guide rod, buffer spring and abutment block, when the electronic components in the cabinet explode, the air pressure generated instantly will impact the panel. At this time, the panel can slide on the guide rod away from the cabinet, and the buffer spring is compressed. The buffer spring can cushion the impact on the panel. After the force is applied, the panel can abut against the abutment block. The abutment block prevents the panel and the guide rod from separating from each other, thereby improving the strength of the charging pile, reducing the phenomenon of damage to the panel when the internal electronic components explode, and enhancing the safety of the charging pile;

[0023] 2. By setting the buffer groove, the card block, the perforation and the card slot, after the buffer spring is sleeved on the guide rod, the abutment block is sleeved on the guide rod, the abutment block slides on the guide rod, the card block is first passed through the perforation, and then the abutment block is rotated to align the card block with the card slot. After the return spring abuts against the abutment block, the card block can be driven to abut against the inner wall of the card slot, thereby quickly connecting the card block to the guide rod, making it convenient to disassemble and assemble the card block and the guide rod, thereby facilitating maintenance of the charging cabinet;

[0024] 3. By setting up the mounting frame, high-pressure tank, nozzle mouth, sealing plug, mounting groove, rack and gear, when the electronic components in the cabinet explode, the air pressure generated instantly will impact the panel. At this time, the panel can slide on the guide rod away from the cabinet, and the rack slides with the enclosure. The rack and the gear are against each other, driving the gear and the sealing plug to rotate. After the sealing plug rotates, it will separate from the nozzle mouth. Due to the high air pressure in the high-pressure tank, the dry powder in the high-pressure tank will be instantly sprayed out through the nozzle mouth the moment the sealing plug separates from the nozzle mouth, and the dry powder is used to extinguish the fire in the charging cabinet, reducing the phenomenon of continuous explosion of the charging cabinet and improving the safety of the charging pile.

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] The embodiment of the present application discloses an explosion-proof new energy charging pile. Figure 1 and Figure 2, which includes a cabinet body 11 and a panel 12. An opening 111 is provided on one side of the cabinet body 11. The panel 12 is provided at the opening 111. The panel 12 and the cabinet body 11 are connected to each other. The panel 12 is used to seal the opening 111 to reduce the phenomenon of dust and impurities entering the cabinet body 11. A number of connecting rods 2 are provided between the panel 12 and the cabinet body 11. In this embodiment, four connecting rods 2 are symmetrically provided. The connecting rods 2 are distributed at the top corners of the connection between the cabinet body 11 and the panel 12. A positioning plate 21 is integrally provided at one end of the connecting rod 2 facing the inner wall of the cabinet body 11, and the positioning plate 21 is connected to the inner wall of the cabinet body 11. A number of support rods 7 are symmetrically fixed at one end of the cabinet body 11 in the direction of the opening 111. The panel 12 is slidably provided on the support rod 7 together, and the support rod 7 can be used to support the panel 12.

[0031] Reference Figure 1 and Figure 2 The end of the connecting rod 2 facing the panel 12 is integrally provided with a connecting plate 22. A guide rod 3 is fixedly provided on the side wall of the connecting plate 22. The length of the guide rod 3 is perpendicular to the surface of the connecting plate 22. The guide rod 3 is arranged in a horizontal direction, and the panel 12 slides together on the guide rod 3. A buffer spring 31 is sleeved on the guide rod 3, and an abutment block 32 is connected to the guide rod 3. One end of the buffer spring 31 abuts against the abutment block 32, and the other end of the buffer spring 31 abuts against the panel 12. When installing the charging pile, first connect the positioning plate 21 on one end of the connecting rod 2 to the inner wall of the cabinet 11, so that the connecting rod 2 is fixed on the inner wall of the cabinet 11, and then the panel 12 is jointly sleeved on the guide rod 3. The panel 12 slides on the guide rod 3 until it fits with the end wall of the cabinet 11, and then the buffer spring 31 is sleeved on the guide rod 3. Finally, the abutment block 32 is fixed on the guide rod 3. The buffer spring 31 drives the panel 12 to fit with the end wall of the cabinet 11 and the surface of the connecting plate 22 at the same time to complete the installation of the cabinet 11. If the electronic components in the cabinet 11 explode, the air pressure generated instantly will impact the panel 12. At this time, the panel 12 can slide on the guide rod 3 away from the cabinet 11, and the buffer spring 31 is compressed. The buffer spring 31 can buffer the impact on the panel 12. After the panel 12 is instantly away from the cabinet 11, the air flow can also flow away from the panel 12 and the cabinet 11. After the panel 12 is subjected to force, it can be abutted against the abutment block 32. The abutment block 32 prevents the panel 12 and the guide rod 3 from separating from each other. After the panel 12 is subjected to force, it can effectively buffer, thereby reducing damage to the panel 12.

[0032] Reference Figure 1 and Figure 2A group of positioning screws 5 are symmetrically arranged on the positioning plate 21. The positioning screws 5 pass through the positioning plate 21 and the end wall of the cabinet 11. The two positioning screws 5 on the positioning plate 21 are commonly connected to the mounting plate 51. The positioning screws 5 are threadedly connected with positioning nuts 52. When installing the connecting rod 2, the positioning nuts 52 on the mounting plate 51 are first passed through the cabinet 11, and then the positioning plate 21 is placed on the positioning screws 5. Finally, the positioning nuts 52 are threadedly connected to the positioning screws 5. The positioning nuts 52 are abutted against the surface of the positioning plate 21, and the mounting plate 51 is abutted against the outer wall of the cabinet 11, so that the connecting rod 2 is quickly fixed to the inner wall of the cabinet 11. The positioning plate 21 and the mounting plate 51 increase the contact area between the connecting rod 2 and the cabinet 11, thereby improving the connection strength between the connecting rod 2 and the cabinet 11.

[0033] Reference Figure 1 and Figure 3 The side of the abutment block 32 facing the buffer spring 31 is provided with a buffer groove 4. The end of the buffer spring 31 away from the panel 12 abuts against the bottom wall of the buffer groove 4, and the buffer spring 31 can be completely retracted into the buffer groove 4. If the panel 12 is subjected to force and hits the buffer spring 31, the panel 12 will slide on the guide rod 3 toward the abutment block 32 due to the impact, and the buffer spring 31 will contract. The buffer spring 31 can be completely retracted into the buffer groove 4, making way for the buffer spring 31, so that the abutment block 32 can contact the panel 12. The abutment block 32 increases the contact area with the panel 12, which can support and limit the panel 12 and reduce the phenomenon of panel 12 breakage.

[0034] Reference Figure 1 and Figure 3 A block 33 is fixedly provided on the guide rod 3. The block 33 is rectangular. The abutment block 32 is sleeved on the guide rod 3. The abutment block 32 can slide or rotate on the guide rod 3. A through-hole 41 for the block 33 to pass through is provided on the end wall of the buffer groove 4. The end wall of the buffer groove 4 is also provided with a slot 42 for the block 33 to be inserted and abutted. After the buffer spring 31 is sleeved on the guide rod 3, the abutment block 32 is sleeved on the guide rod 3. The abutment block 32 slides on the guide rod 3. The block 33 is first passed through the through-hole 41, and then the abutment block 32 is rotated and aligned with the slot 42. After the return spring abuts against the abutment block 32, the block 33 can be driven to abut against the inner wall of the slot 42, thereby quickly connecting the block 33 to the guide rod 3, making it easy to disassemble and assemble the block 33 and the guide rod 3, thereby facilitating maintenance of the charging cabinet.

[0035] Reference Figure 1A reinforcing rod 6 is provided between adjacent abutment blocks 32. The length direction of the reinforcing rod 6 is arranged along the length direction of the cabinet body 11. Dovetail blocks 61 are integrally provided at both ends of the reinforcing rod 6. Dovetail grooves 62 for inserting the dovetail blocks 61 are provided on the end walls of the abutment blocks 32. The dovetail blocks 61 and the dovetail grooves 62 are adapted to each other. After the abutment blocks 32 are fixed to the guide rod 3, the dovetail blocks 61 at both ends of the reinforcing rod 6 are inserted into the dovetail grooves 62 on the adjacent abutment blocks 32. The dovetail blocks 61 abut against the inner walls of the dovetail grooves 62 to connect the reinforcing rod 6 between the adjacent abutment blocks 32. The reinforcing rod 6 can improve the connection strength between the adjacent guide rods 3. When the enclosure is hit and slides toward the abutment block 32, the reinforcing rod 6 can also abut against the side wall of the enclosure. The reinforcing rod 6 further supports the enclosure and improves the strength of the enclosure.

[0036] Reference Figure 1 and Figure 2 A mounting bracket 8 is fixedly provided on the outer wall of the cabinet 11. A high-pressure tank 81 for storing dry powder is provided on the mounting bracket 8. High pressure is formed in the high-pressure tank 81 by pressurization. A nozzle opening 82 is connected to the high-pressure tank 81. A sealing plug 83 is threadedly connected to the nozzle opening 82. A mounting groove 112 is provided on the cabinet 11 for the nozzle opening 82 and the sealing plug 83 to pass through. A linkage assembly 9 is provided between the panel 12 and the sealing plug 83. The linkage assembly 9 includes a rack 91 and a gear 92. The gear 92 is provided on the outer wall of the sealing plug 83. The gear 92 and the sealing plug 83 are coaxially arranged. The gear 92 can pass through the mounting groove 112. The rack 91 is fixedly provided on the side of the panel 12 facing the opening 111. The length direction of the rack 91 is arranged along the width direction of the cabinet 11. The rack 91 and the gear 92 are meshed with each other. When installing the high-pressure tank 81, pass the sealing plug 83 and the nozzle mouth 82 through the installation groove 112 to make the gear 92 and the rack 91 engage with each other. When the electronic components in the cabinet 11 explode, the air pressure generated instantly will impact the panel 12. At this time, the panel 12 can slide on the guide rod 3 in the direction away from the cabinet 11, and the rack 91 slides with the enclosure. The rack 91 and the gear 92 are against each other, driving the gear 92 and the sealing plug 83 to rotate. After the sealing plug 83 rotates, it will disengage from the nozzle mouth 82. Due to the high air pressure in the high-pressure tank 81, the dry powder in the high-pressure tank 81 is instantly sprayed out through the nozzle mouth 82 at the moment the sealing plug 83 disengages from the nozzle mouth 82, and the dry powder is used to extinguish the fire in the charging cabinet, reducing the phenomenon of continuous explosion of the charging cabinet and improving the safety of the charging pile.

[0037] The implementation principle of an explosion-proof new energy charging pile in the embodiment of the present application is as follows: if the electronic components in the cabinet 11 explode, the air pressure generated instantly will impact the panel 12. At this time, the panel 12 can slide on the guide rod 3 in the direction away from the cabinet 11, and the buffer spring 31 is compressed by force. The buffer spring 31 can buffer the impact on the panel 12. After the panel 12 is instantly away from the cabinet 11, the air flow can also flow away from the panel 12 and the cabinet 11. After the panel 12 is subjected to force, it can be abutted against the abutment block 32. The abutment block 32 supports and limits the panel 12. The abutment block 32 prevents the panel 12 from separating from the guide rod 3. The connecting rod 2 improves the strength of the charging pile. The guide rod 3 and the buffer spring 31 can buffer the panel 12 when it is subjected to force, reducing the phenomenon of damage to the panel 12 when the internal electronic components explode, thereby enhancing the safety of the charging pile. The structure is single-order, easy to assemble, and low in cost.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
