Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and specifically to a charging pile with an automatic alarm function. Background Technology

[0002] A charging pile is a charging device for new energy electric vehicles. It typically consists of a cabinet and wires extending from inside the cabinet. A charging gun is connected to the end of the wires. When not in use, the charging gun is inserted into the side of the cabinet to prevent damage to the connection end of the gun. To allow the charging gun head to travel further for charging, the wires are manufactured with extra length. However, these extra wires are usually dragged on the ground. During use, the wires frequently rub against the ground, and they are also easily run over by cars. This not only affects the lifespan of the wires but also poses safety hazards (for example, after the surface of the wires wears down to a certain extent, the metal inside the wires may be exposed, which can easily lead to safety accidents). Summary of the Invention

[0003] Technical problems to be solved In view of the above-mentioned shortcomings of the existing technology, the present invention provides a charging pile with an automatic alarm function, which can effectively solve the problem that in order to move the charging gun head to a greater distance for charging, the existing technology will manufacture the wire with excess length during the manufacturing process. However, this excess wire is usually dragged on the ground. During use, the wire is often in contact with the ground and is also easy to be run over by cars. This not only affects the service life of the wire, but also easily causes safety hazards.

[0004] Technical solution To achieve the above objectives, the present invention provides the following technical solution: This invention provides a charging pile with an automatic alarm function, including a cabinet. Both sides of the cabinet are provided with mounting cavities. A sealing plate is provided at the opening of each mounting cavity. The sealing plate is provided with an insertion end for inserting a charging gun and a winding assembly for retrieving the charging wire. A buzzer for emitting an alarm signal is provided below the insertion end. The winding assembly includes a winding shaft rotatably mounted inside the mounting cavity. One end of the winding shaft extends out of the mounting cavity, and a winding roller is coaxially fixedly mounted on the end of the winding shaft extending out of the mounting cavity. A mounting bearing is fixedly installed on the closed plate. The middle part of the winding shaft passes through the mounting bearing and is rotatably mounted on the inner side of the mounting bearing. A drive motor for driving the winding shaft to rotate is fixedly installed inside the mounting cavity. Multiple limiting grooves are distributed in a circumferential array on the end face of the winding roller facing the winding shaft. A limiting block for locking in the limiting groove is provided on the mounting bearing.

[0005] Furthermore, the limiting block is slidably installed inside the mounting bearing, and a stop block is slidably installed on the side of the mounting bearing away from the winding roller. The limiting block is elastically installed on one side of the stop block, and an elastic element is provided on the stop block for driving the stop block to move away from the winding roller. A linkage plate for driving the stop block to move towards the winding roller is slidably installed up and down on the inner side of the sealing plate.

[0006] Furthermore, a U-shaped plate is provided on the side of the abutment facing the winding roller, and the end of the limiting block facing the abutment is slidably installed inside the U-shaped plate. An elastic plate is provided between the abutment and the inner wall of the U-shaped plate. The elastic plate is used to drive the abutment and the U-shaped plate away from each other. When the linkage plate moves downward, it drives the abutment to move downward, thereby driving the limiting block to extend into the limiting groove. The elastic stiffness of the elastic element is greater than the elastic stiffness of the elastic plate.

[0007] Furthermore, a linkage gear is rotatably installed inside the mounting cavity. The linkage gear is connected to the drive motor. A pinion is coaxially fixedly installed on the linkage gear. A gear row that meshes with the pinion is provided in the middle of the linkage plate. When the linkage gear rotates, it drives the linkage plate to move up and down through the pinion.

[0008] Furthermore, the insertion end is fixedly mounted on the sealing plate and located directly above the winding assembly. Both sides of the insertion end have sliding grooves, and both sides of the insertion end are slidably mounted with sliding rods. The sliding rods are provided with protruding plates for extending into the sliding grooves to lock the charging gun.

[0009] Furthermore, the slide rods on both sides of each insertion end are fixedly mounted on the linkage plate, and the slide rods move up and down as the linkage plate moves up and down.

[0010] Furthermore, the slide bar has an installation groove on the side facing the insertion end, the extension plate is slidably installed inside the installation groove, the installation groove has a spring inside, the spring is used to drive the extension plate to slide towards the insertion end, and the side of the extension plate has an inclined surface.

[0011] Furthermore, a detection groove is provided on the side of the protruding plate facing the insertion end, and a laser emitter and a receiver are respectively provided inside the detection groove of the two protruding plates on both sides of each insertion end.

[0012] Furthermore, a shielding plate is provided on the outer side of the closed plate. The side view projection outline of the shielding plate is U-shaped, and the shielding plate covers the winding roller in a semi-enclosed shape.

[0013] Beneficial effects The technical solution provided by this invention has the following advantages compared with known public technologies: In this invention, two winding rollers are respectively set on both sides of the cabinet, and a winding shaft is set inside the installation cavity. After charging is completed, the winding shaft can be driven by the drive motor to rotate. During the rotation of the winding shaft, the winding rollers will rotate to retract the wire. After the next charging is started, the drive motor rotates in the opposite direction to release a certain length of wire, so as to avoid the wire from dragging on the ground and causing excessive wear.

[0014] In this invention, by setting a U-shaped plate on the abutment block and connecting the limiting block to the inner wall of the U-shaped plate through an elastic plate, when the abutment block is in the state closest to the winding roller, the limiting block can be allowed to move towards the abutment block, and the winding roller can be allowed to rotate at this time. The function of the limiting block is not to lock the position of the winding roller, but only to increase the torque required for the rotation of the winding roller, so as to prevent the winding roller from being manually rotated when the charging gun is not in use.

[0015] In this invention, an installation groove is provided inside the slide rod, and the extension plate is slidably installed inside the installation groove. At the same time, an inclined surface is provided at the lower end of the extension plate. When the charging gun is not fully inserted into the insertion end, the slide rod moves downward and drives the extension plate downward without squeezing the side of the charging gun head. At this time, the extension plate will compress the spring, causing the extension plate to retract into the installation groove. At the same time, a buzzer alarm will be triggered to remind the charging personnel to insert the charging gun head properly. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to embodiments.

[0021] Example: A charging pile with automatic alarm function, such as Figure 1 - Figure 4 As shown, the device includes a cabinet 1, with a control panel on the outside of the cabinet 1 for controlling the start and stop of charging. Both sides of the cabinet 1 have mounting cavities 101, with a closing plate 22 at the opening of each mounting cavity 101. The closing plate 22 has an insertion end 2 for inserting a charging gun and a winding assembly 3 for retrieving the charging wire. Below the insertion end 2 is a buzzer 21 for emitting an alarm signal. The winding assembly 3 includes a winding shaft 32 rotatably mounted inside the mounting cavity 101, with one end of the winding shaft 32 extending out of the mounting cavity 101. A winding roller 33 is coaxially fixedly mounted on the end of the winding shaft 32 extending out of the mounting cavity 101. A mounting bearing 35 is fixedly installed on the closed plate 22. The middle part of the winding shaft 32 passes through the mounting bearing 35 and is rotatably mounted inside the mounting bearing 35. A drive motor 31 for driving the winding shaft 32 to rotate is fixedly installed inside the mounting cavity 101. The end face of the winding roller 33 facing the winding shaft 32 has a plurality of limiting grooves 3301 arranged in a circumferential array. A limiting block 36 for locking in the limiting groove 3301 is provided on the mounting bearing 35.

[0022] In this invention, two winding rollers 33 are respectively set on both sides of the cabinet 1, and a winding shaft 32 is set inside the mounting cavity 101. After charging is completed, the winding shaft 32 can be driven to rotate by the drive motor 31. During the rotation of the winding shaft 32, the winding rollers 33 will rotate to retract the wire. After the next charging is started, the drive motor 31 rotates in the opposite direction to release a certain length of wire to avoid the wire from dragging on the ground and causing excessive wear.

[0023] It should be noted that by setting a limiting block 36 on the mounting bearing 35 and setting multiple limiting grooves 3301 on the side of the winding roller 33, when the limiting block 36 is inserted into the limiting groove 3301, the winding roller 33 can only rotate in the direction of retrieving the wire; the drive motor 31 drives the winding roller 33 to rotate through gear engagement, and the transmission is carried out by a smaller gear driving a larger gear, so that the drive motor 31 can drive the winding roller 33 to rotate more easily.

[0024] Furthermore, such as Figure 4 and Figure 5 As shown, the limiting block 36 is slidably installed inside the mounting bearing 35. A stop block 37 is slidably installed on the side of the mounting bearing 35 away from the winding roller 33. The limiting block 36 is elastically installed on one side of the stop block 37. An elastic element 371 is provided on the stop block 37 for driving the stop block 37 to move away from the winding roller 33. A linkage plate 4 is slidably installed up and down on the inner side of the sealing plate 22 for driving the stop block 37 to move towards the winding roller 33.

[0025] Specifically, by sliding the abutment 37 on one side of the bearing 35 and installing the limiting block 36 on the side of the abutment 37 close to the winding roller 33, when it is necessary to limit the winding roller 33, the abutment 37 can be moved toward the winding roller 33 by pressing down the linkage plate 4, thereby driving the end of the limiting block 36 away from the abutment 37 to be inserted into the limiting groove 3301. The top view projection shape of the limiting groove 3301 is triangular. The elastic element 371 can drive the limiting block 36 and the abutment 37 to move away from the winding roller 33 after the linkage plate 4 moves up. In actual use, the elastic element 371 can be a spring.

[0026] Furthermore, such as Figure 5 and Figure 6 As shown, a U-shaped plate 372 is provided on the side of the abutment 37 facing the winding roller 33. The limiting block 36 is slidably installed inside the U-shaped plate 372 at the end facing the abutment 37. An elastic plate 361 is provided between the abutment 37 and the inner wall of the U-shaped plate 372. The elastic plate 361 is used to drive the abutment 37 and the U-shaped plate 372 away from each other. When the linkage plate 4 moves downward, it drives the abutment 37 to move downward, thereby driving the limiting block 36 to extend into the limiting groove 3301. The elastic stiffness of the elastic element 371 is greater than the elastic stiffness of the elastic plate 361.

[0027] Specifically, by setting a U-shaped plate 372 on the abutment block 37 and connecting the limiting block 36 to the inner wall of the U-shaped plate 372 through the elastic plate 361, when the abutment block 37 is in the state closest to the winding roller 33, the limiting block 36 can be allowed to move towards the abutment block 37 (i.e., compress the elastic plate 361), at which time the winding roller 33 can be allowed to rotate. The function of the limiting block 36 is not to lock the position of the winding roller 33, but only to increase the torque required for the rotation of the winding roller 33, so as to prevent the winding roller 33 from being manually rotated when the charging gun is not in use.

[0028] Furthermore, such as Figure 7 and Figure 8 As shown, a linkage gear 34 is rotatably mounted inside the mounting cavity 101. The linkage gear 34 is connected to the drive motor 31. A pinion 341 is coaxially fixedly mounted on the linkage gear 34. A gear row 43 that meshes with the pinion 341 is provided in the middle of the linkage plate 4. When the linkage gear 34 rotates, it drives the linkage plate 4 to move up and down through the pinion 341.

[0029] In this configuration, by setting a toothed rack 43 on the linkage plate 4 and a pinion 341 on the linkage gear 34, when the drive motor 31 drives the winding roller 33 to wind the wire, it can also drive the linkage plate 4 to move downward, so that the lower end of the linkage plate 4 drives the abutment block 37 to move toward the winding roller 33.

[0030] Furthermore, such as Figure 8 and Figure 9 As shown, the insertion end 2 is fixedly installed on the closed plate 22 and located directly above the winding assembly 3. Both sides of the insertion end 2 have sliding grooves 201, and both sides of the insertion end 2 are slidably installed with sliding rods 41. The sliding rods 41 are provided with protruding plates 42 for extending into the sliding grooves 201 to lock the charging gun. The sliding rods 41 on both sides of each insertion end 2 are fixedly installed on the linkage plate 4. When the linkage plate 4 moves up and down, it drives the sliding rods 41 to move up and down.

[0031] Specifically, by setting slide rods 41 on both sides of the top of each linkage plate 4, when the linkage plate 4 moves down to the lowest end, the protruding plate 42 on the side of the slide rod 41 can be driven to lock the charging gun head on both sides, which can achieve the effect of locking the position of the charging gun head; grooves corresponding to the positions of the protruding plate 42 are provided on both sides of the charging gun head.

[0032] It should be noted that when the car needs to be charged, the wire is released through the control panel. At this time, the drive motor 31 rotates in the reverse direction, which drives the winding roller 33 to rotate in the reverse direction. At the same time, the linkage plate 4 also moves upward during the reverse rotation of the pinion 341, causing the slide bar 41 to move upward. At this time, the extension plate 42 releases the lock on the charging gun head, and the charging gun head can be easily removed.

[0033] Furthermore, such as Figure 8 and Figure 9 As shown, the slide bar 41 has a mounting groove 4101 on the side facing the insertion end 2. The extension plate 42 is slidably installed inside the mounting groove 4101. A spring 421 is installed inside the mounting groove 4101. The spring 421 is used to drive the extension plate 42 to slide towards the insertion end 2. An inclined surface 4202 is provided on the side of the extension plate 42 facing the insertion end 2. A detection groove 4201 is provided on the side of the extension plate 42 facing the insertion end 2. A laser emitter and a receiver are respectively installed inside the detection grooves 4201 of the two extension plates 42 on both sides of the insertion end 2.

[0034] The system incorporates a mounting groove 4101 inside the slide bar 41, allowing the extension plate 42 to slide within it. An inclined surface 4202 is provided at the lower end of the extension plate 42. When the charging gun is not fully inserted into the insertion end 2, the slide bar 41 moves downwards, causing the extension plate 42 to move downwards without pressing against the side of the charging gun head. At this time, the extension plate 42 compresses the spring 421, causing it to retract into the mounting groove 4101. Simultaneously, a buzzer 21 is triggered to alert the user to properly insert the charging gun head. A laser emitter and receiver detect the presence of the charging gun head in the insertion end 2. When the extension plate 42 slides into the groove 201, the charging gun head is not inside the insertion end 2 (this is determined by the laser emitter and receiver; if the receiver can receive the laser emitted by the emitter, the charging gun head is not inside the insertion end 2; otherwise, it is). A common model example is Keyence LV-N. Series: for example, LV-NH62, LV-NH67), the side buzzer 21 emits an alarm.

[0035] In addition, when the charging gun head is fully inserted into the insertion end 2, when the slide bar 41 moves the extension plate 42 down to the bottom, the extension plate 42 will be stuck in the grooves on both sides of the charging gun head, fixing the position of the charging gun head. At this time, the extension plate 42 is not squeezed, and the receiver cannot receive the laser signal emitted by the transmitter. At this time, the buzzer 21 will not sound an alarm. When the charging gun head is not fully inserted into the insertion end 2, the slide bar 41 moves the extension plate 42 down to the bottom. The extension plate 42 will be squeezed into the mounting slot 4101, which will trigger the buzzer 21 to sound an alarm. When the charging gun head is not inserted into the insertion end 2, the slide bar 41 moves the extension plate 42 down to the bottom. The extension plate 42 slides down into the slide groove 201 and causes the laser emitter to emit a laser signal. At this time, the laser receiver can receive the laser signal and trigger the buzzer 21 to issue an alarm.

[0036] Furthermore, a shielding plate 23 is provided on the outer side of the closed plate 22. The side view projection outline of the shielding plate 23 is U-shaped, and the shielding plate 23 covers the winding roller 33 in a semi-enclosed shape.

[0037] In particular, by setting a semi-enclosed shield 23 on the side of the closed plate 22, the winding roller 33 can be covered from below, which can protect the wire.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
