Description

Technical Field

[0001] This utility model relates to the field of intelligent transportation systems, and more specifically, to a switch applied to electric vehicle route planning. Background Technology

[0002] With increasing public concern about environmental protection and energy supply, electric vehicles are poised to replace traditional gasoline-powered vehicles as a crucial component of the transportation system. Therefore, by comprehensively considering factors influencing electric vehicle route planning, and establishing a route planning model that integrates user travel time, distance, and charging costs, different travel routes can be planned for electric vehicle users, better meeting their travel needs.

[0003] To meet the requirements of electric vehicle route planning, a large amount of data needs to be collected, requiring high-speed data transmission capabilities and stable network connections. Therefore, switches are indispensable devices. A switch is a network device used for forwarding electrical (optical) signals, providing a dedicated electrical signal path for any two network nodes connected to the switch. Currently, if switches are embedded in cabinets or other equipment, they are typically inserted directly into the cabinet and secured using mounting lugs on both sides with bolts. While this method achieves embedded installation, it is cumbersome to install and remove, and rusted bolts hinder rapid maintenance and repair. Furthermore, because a large number of embedded switches are typically used in communication engineering, the workload of disassembling and reassembling switches in case of malfunction or maintenance is enormous, further hindering rapid maintenance and repair. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a switch for electric vehicle route planning, so as to solve the technical problem that the current embedded installation of switches is not convenient for quick assembly and disassembly.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a switch for electric vehicle route planning, comprising a switch body, a concave shell arranged on the switch body, fixing ears arranged at both ends of the concave shell, a concave slot arranged on the inner wall of the concave shell, the concave shell being inserted into the concave slot, a top fixing plate movably arranged on the rear side of the concave slot, and several sets of first springs equidistantly arranged between the top fixing plate and the opposite side of the concave slot, rectangular slots opening at the top and bottom of the two ends of the concave slot, a stop block slidably arranged inside the rectangular slot, the top of the stop block being an inclined surface, and a second spring arranged on the opposite side of the stop block and the rectangular slot;

[0006] A mounting plate is arranged at the bottom of one side of the stop block. The stop block and the mounting plate are combined in an L-shape. Two sets of symmetrical reset elastic rods are movably arranged on the mounting plate. A release block is movably arranged on the side of the stop block facing the mounting plate. The top of the release block is an inclined surface. The inclined surfaces of the stop block and the release block are arranged opposite to each other. The inclined surface of the stop block faces outward, and the inclined surface of the release block faces inward.

[0007] Preferably, a sliding groove is provided inside the rectangular slot, and a slider corresponding to the sliding groove is arranged on the stop block, with the slider located inside the sliding groove.

[0008] Preferably, the concave shell has a heat-conducting cavity inside, and the heat-conducting cavity has openings at both ends. The concave shell has opening slots on both sides inside, and the opening slots correspond to the side heat dissipation vents of the concave shell. The opening slots are connected to the heat-conducting cavity.

[0009] Preferably, the stop block has a guide groove facing the side of the release block, and an L-shaped groove is formed on the inner side of the guide groove. A guide block is arranged on the side of the release block facing the stop block, and the guide block extends into the guide groove. A protrusion is arranged on the side of the guide block, and the protrusion is located in the L-shaped groove.

[0010] Preferably, the distance between the stop block and the release block is the same as the distance between the guide block and the side of the L-shaped groove, and the distance between the guide block and the bottom of the L-shaped groove is the same as the vertical distance between the release block inclined surface.

[0011] Preferably, the reset elastic rod includes an I-shaped rod, which is arranged through the mounting plate. A third spring is fitted on the I-shaped rod, and a ball bearing is movably arranged at the top of the I-shaped rod, with the ball bearing in contact with the release block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model features a concave housing with a concave slot on its inner wall. A top fixing plate is elastically installed within the concave slot, and stop blocks are elastically installed at the top and bottom of both ends of the concave slot. The top of the stop blocks is inclined. Therefore, when the switch body is embedded and installed in an external cabinet, the concave housing can be directly inserted into the external cabinet. The fixing ears of the concave housing are fixed with bolts. Then, the switch body is inserted into the concave slot of the concave housing. When the switch body is inserted, the inclined surface of the stop blocks will press the stop blocks into the rectangular slot. When the switch body is fully inserted... After insertion, the stop block rises and resets to shield the switch body, allowing for quick and secure installation.

With the cooperation of the L-shaped groove of the guide groove and the protrusion of the guide block, the release block can slide in an L-shape on the stop block. Therefore, when it is necessary to remove the switch body, the switch body can be pushed backward a certain distance. At this time, with the cooperation of the reset elastic rod, the release block rises and resets, and then it can be released. Open the switch body and pull it outwards. At this time, the ejector block will move horizontally until it sticks to the stop block. Then, with the cooperation of the inclined surface of the ejector block, it will push the ejector block and the stop block together into the rectangular slot until they are fully inserted into the rectangular slot. At this time, the personnel can directly pull out the switch body quickly without the need for the personnel to manually press the stop block at the concave slot port into the rectangular slot. The switch body can be pulled out directly, which can further improve the convenience of disassembling and assembling the switch body, and make it more convenient for personnel to maintain and repair the switch body.

[0025] like Figures 1 to 8 As shown, this utility model relates to a switch for electric vehicle route planning, including a switch body 1, a concave shell 2 arranged on the switch body 1, fixing ears 3 arranged at both ends of the concave shell 2, a concave slot 4 arranged on the inner wall of the concave shell 2, the concave shell 2 being inserted into the concave slot 4, a top fixing plate 7 movably arranged on the rear side of the concave slot 4, and several sets of first springs 701 equidistantly arranged between the top fixing plate 7 and the opposite side of the concave slot 4, rectangular slots 5 opened at the top and bottom of the two ends of the concave slot 4, a stop block 8 slidably arranged inside the rectangular slot 5, the top of the stop block 8 being an inclined surface, and a second spring 6 arranged on the opposite side of the stop block 8 and the rectangular slot 5.

[0026] When the switch body 1 is embedded and installed in the external cabinet, the concave housing 2 can be directly inserted into the external cabinet. The fixing ears 3 of the concave housing 2 are fixed by bolts. Then, the switch body 1 is inserted into the concave slot 4 of the concave housing 2. When the switch body 1 is inserted, the inclined surface of the stop block 8 will press the stop block 8 into the rectangular slot 5. When the switch body 1 is fully inserted, the stop block 8 will rise and reset under the cooperation of the second spring 6 to block the switch body 1. This can quickly achieve the fixed installation of the switch body 1. In addition, the top plate 7 will push the front of the switch body 1 under the cooperation of the first spring 701, which, together with the stop block 8, can ensure the stability of the installation of the switch body 1. Conversely, pressing the stop block 8 into the rectangular slot 5 can also quickly pull out the switch body 1. This can achieve quick disassembly and assembly of the switch body 1, which is convenient for personnel to maintain and repair the switch body 1.

[0027] Specifically, a sliding groove 501 is provided inside the rectangular slot 5, and a slider 801 corresponding to the sliding groove 501 is arranged on the stop block 8, and the slider 801 is located inside the sliding groove 501; with the cooperation of the sliding groove 501 and the slider 801, the stop block 8 can be slidably installed inside the rectangular slot 5.

[0028] Furthermore, a heat-conducting cavity 202 is provided inside the concave housing 2, and the heat-conducting cavity 202 is open at both ends. Opening slots 201 are provided on both sides inside the concave housing 2, and the opening slots 201 correspond to the side heat dissipation vents of the concave housing 2. The opening slots 201 are connected to the heat-conducting cavity 202. When the switch body 1 is working, the heat emitted from the heat dissipation vents on both sides enters the heat-conducting cavity 202 through the opening slots 201, and then the heat is discharged through the two ports of the heat-conducting cavity 202, which can ensure the heat dissipation effect of the switch body 1 after embedded installation.

[0029] In this embodiment of the utility model, a mounting plate 9 is arranged at the bottom of one side of the stop block 8. The stop block 8 and the mounting plate 9 are combined in an L-shape.

The top of the release block 10 is an inclined surface. The inclined surfaces of the stop block 8 and the release block 10 are arranged opposite to each other, with the inclined surface of the stop block 8 facing outward and the inclined surface of the release block 10 facing inward. A guide groove 802 is opened on the side of the stop block 8 facing the release block 10. An L-shaped groove 803 is provided on the inner side of the 802. A guide block 1001 is arranged on the side of the release block 10 facing the stop block 8. The guide block 1001 extends into the guide groove 802. A protruding block 1002 is arranged on the side of the guide block 1001 and is located in the L-shaped groove 803. The distance between the stop block 8 and the release block 10 is the same as the distance between the guide block 1001 and the side of the L-shaped groove 803. The distance between the bottom of the guide block 1001 and the L-shaped groove 803 is the same as the vertical distance of the inclined surface of the release block 10.

[0030] When it is necessary to remove the switch body 1, the switch body 1 can be pushed backward a distance. At this time, with the cooperation of the reset elastic rod 11, the release block 10 rises and resets. Then, the switch body 1 is released and pulled outward. At this time, the release block 10 will move horizontally until it sticks to the stop block 8. Then, with the cooperation of the inclined surface of the release block 10, the release block 10 and the stop block 8 will be pushed together into the rectangular slot 5 until they are fully inserted into the rectangular slot 5. At this time, the personnel can directly pull out the switch body 1 quickly without the need for the personnel to manually press the stop block 8 at the concave slot 4 port into the rectangular slot 5. The switch body 1 can be pulled out directly, which can further improve the convenience of disassembling and assembling the switch body 1, and make the maintenance and repair of the switch body 1 more convenient.

[0031] Specifically, the reset elastic rod 11 includes an I-shaped rod 1101, which is arranged through the mounting plate 9. A third spring 1102 is fitted on the I-shaped rod 1101, and a ball bearing 1103 is movably arranged at the top of the I-shaped rod 1101, and the ball bearing 1103 contacts the release block 10.
