A new energy charging gun anti-drag charging pile

Abstract

The present application provides a new energy charging gun anti-drag charging pile, which relates to the technical field of new energy charging piles. A new energy charging gun anti-drag charging pile includes a charging pile and a charging gun, wherein the charging gun includes a gun tail, a gun body and a gun head, and an axial deflection angle is provided between the gun tail and the gun body; an autonomous pop-up mechanism is sleeved on the outer side of the gun body, and the autonomous pop-up mechanism slides elastically along the axial direction of the gun body. When the gun tail is dragged by a lateral force, the gun tail will deflect relative to the gun body, and then drive a deviation between the limiting component and the abutment plate, triggering the autonomous elastic mechanism to release the locked state and eject in the direction of the vehicle body. During this process, the autonomous ejection mechanism drives the switch displacement to synchronously release the lock between the charging gun and the vehicle body, and then the charging gun is automatically detached from the vehicle body under the displacement of the autonomous ejection mechanism, avoiding the damage caused by dragging between the charging gun and the charging pile due to vehicle driving.

Description

Technical Field

[0001] The present application relates to the technical field of new energy charging piles, and in particular to a new energy charging gun drag-proof charging pile. Background Art

[0002] When using new energy charging piles, drivers often forget to unplug the charging gun and drive away directly, causing strong dragging and damage between the charging gun and the charging pile. Although existing charging piles also have anti-drag functions, they can only solve the dragging phenomenon caused by the pulling force along the length of the charging gun. As we all know, the charging ports of new energy vehicles are not all set at the front and rear ends of the vehicle body, and many are set on one side of the vehicle body. At this time, if the charging gun is not unplugged and the vehicle is driven away directly, the charging gun will be subjected to lateral drag. In this way, the existing anti-drag charging piles can hardly make the charging gun detach from the vehicle body on its own, and will still cause damage between the charging gun and the charging pile.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0034] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] Example 1, as Figures 1-13 As shown, according to an embodiment of the present application, a new energy charging gun anti-drag charging pile includes a charging pile 1 and a charging gun 2 that can be actively retracted to the charging pile 1, a cable 24 is connected between the charging gun 2 and the charging pile 1, and the charging gun 2 includes a gun tail 21, a gun body 22 and a gun head 23 that are connected to each other. It should be noted that in the specific embodiment of the present application, an automatic winding device is provided inside the charging pile 1 (the existing technology is very mature, and its working principle is not described here), which is used to use the winding cable 24 to retract the charging gun 2 to the charging pile 1 after the charging gun 2 falls to the ground. The electrical connection between the cable 24 and the charging gun 2 is a mature existing technology. In the specific embodiment of the present application, as shown in FIG. Figure 4The figure is shown for reference only, and the related electrical components are not described in detail in this application.

[0036] Specifically, such as Figure 3-Figure 5 As shown, a bellows 25 is connected between the gun tail 21 and the gun body 22. The gun body 22 is elastically plugged into the gun tail 21, and there is a certain axial deflection angle between the gun tail 21 and the gun body 22. It can be understood that, as shown in FIG. Figure 1 As shown, when the charging port of the vehicle is on the side of the vehicle body, if the charging gun 2 is not unplugged and the vehicle starts to move away, the charging gun 2 will be subjected to lateral tension exerted by the cable 24. The axial deflection angle between the gun tail 21 and the gun body 22 can cause the gun tail 21 to deflect to a certain extent equivalent to the gun body 22 when the cable 24 exerts tension.

[0037] In a specific embodiment of the present application, the gun body 22 is provided with a switch 26 , which is displaced in the radial direction of the gun body 22 to release the locking state between the charging gun 2 and the vehicle body.

[0038] An autonomous pop-up mechanism 3 is sleeved on the outside of the gun body 22, and the autonomous pop-up mechanism 3 slides elastically along the axial direction of the gun body 22. During the sliding of the autonomous pop-up mechanism 3, the pressure switch 26 is displaced toward the inside of the gun body 22 and the contact between the charging gun 2 and the new energy vehicle is locked. It can be understood that through the elastic sliding of the autonomous pop-up mechanism 3 on the gun body 22, when it touches the vehicle body, it will apply a reverse force to the charging gun 2, so that the charging gun 2 can be autonomously detached from the vehicle body.

[0039] One end of the autonomous pop-up mechanism 3 is provided with a plurality of positioning members 34, which include a plurality of circumferentially arranged first hinge blocks 341 and second hinge blocks 342, the first hinge blocks 341 and the second hinge blocks 342 being hinged to each other, and the first hinge blocks 341 and the second hinge blocks 342 being hinged to each other, and the first hinge blocks 341 and the second hinge blocks 342 can form a semi-overlapping shape and a straightened shape, such as Figure 8 and Figure 9 As shown, the first hinge block 341 and the second hinge block 342 can cause the components at both ends to undergo axial relative displacement through their own hinge, and can use their own deformation to enable the autonomous ejection mechanism 3 to form a locked state and an unlocked state on the gun body 22.

[0040] A limiting mechanism 4 for triggering and limiting the displacement of the autonomous ejection mechanism 3 is provided between the gun tail 21 and the gun body 22. The limiting mechanism 4 includes two limiting components 41 symmetrically arranged on both sides of the gun tail 21, and an abutment plate 42 slidably sleeved on the gun body 22. The limiting component 41 is elastically inserted into the gun tail 21, and the other end of the limiting component 41 abuts against the abutment plate 42. The abutment plate 42 elastically abuts against one end of the autonomous ejection mechanism 3 and forms a semi-jointed connection between the first hinge block 341 and the second hinge block 342. In an overlapping shape, notches 421 are provided on both sides of the contact position between the abutment plate 42 and the limiting assembly 41. It can be understood that when the tail portion 21 of the gun is equivalent to the gun body portion 22 and an axial deflection occurs, the limiting assembly 41 will be offset from the position originally abutting against the abutment plate 42 to the inside of the notch 421, so that the abutment plate 42 loses its abutting force, and then the positioning member 34 loses its extrusion force and undergoes radial shrinkage deformation, so that the autonomous ejection mechanism 3 triggers an axial ejection displacement when the gun body portion 22 is unlocked.

[0041] Specifically, such as Figure 3-Figure 5 As shown, an end ring 211 is provided at one end of the gun tail portion 21 facing the gun body portion 22, and a flange 212 is provided on the side of the end ring 211 extending into the gun tail portion 21, with the flange 212 facing the gun tail portion 21. Two baffles 213 are symmetrically fixedly connected to one side of the end ring 211 located on the outer side of the gun tail portion 21, and three elastic columns 214 are fixedly connected circumferentially on the end ring 211. One end of the bellows 25 is coaxially fixed to the end ring 211.

[0042] An I-shaped cylinder 221 is provided at one end of the gun body 22 facing the gun tail 21 , and the I-shaped cylinder 221 is partially movably plugged into the end ring 211 . It should be noted here that a certain angle of axial deflection can occur between the I-shaped cylinder 221 and the end ring 211 .

[0043] A first spring 222 is provided between the end ring 211 and a portion of the I-shaped cylinder 221 located inside the gun tail 21 . The first spring 222 is sleeved on the I-shaped cylinder 221 , and the flange 212 can provide a certain axial positioning effect on the first spring 222 .

[0044] It should be noted that the elastic column 214 is inserted into the end of the I-shaped cylinder 221 located outside the gun tail portion 21, so that the gun tail portion 21 that is not subjected to the drag force remains fixed relative to the gun body portion 22. It is understandable that when the gun tail portion 21 deflects axially relative to the gun body portion 22, the elastic column 214 will be subjected to the force and axially twisted, and then may fall off the I-shaped cylinder 221.

[0045] Among them, the outer coaxial fixed sleeve of the gun body 22 is provided with a first retaining ring 223 and a second retaining ring 224, the outer wall of the gun body 22 is axially fixed with a handle 225, the handle 225 is fixed with a stopper 226, and the switch 26 is arranged between the first retaining ring 223 and the second retaining ring 224.

[0046] like Figure 5-Figure 7 As shown, the switch 26 includes a pressing end 261 radially inserted into the side wall of the gun body 22 (it should be noted here that the pressing end 261 slides radially on the side wall of the gun body 22, that is, the pressing end 261 will not be completely displaced to the inner side of the gun body 22), and one end of the pressing end 261 extending into the gun body 22 is fixedly connected to a transmission block 262, and one end of the transmission block 262 is fixedly connected to a limiting end 263. Limiting blocks 264 are symmetrically provided on both sides of the limiting end 263. The limiting blocks 264 slide between the end surface of the gun body 22 toward the gun head 23, and one end of the limiting end 263 extends out of the gun body 22 and is provided A locking protrusion is provided, and a plurality of guide posts 265 are slidably inserted on the transmission block 262. The plurality of guide posts 265 are fixedly connected to the inner side of the gun body 22. A second spring 266 for resetting the pressing end 261 is sleeved on the guide post 265. It can be understood that when the pressing end 261 is subjected to radial pressure, it will be displaced radially toward the inner side of the gun body 22 and synchronously drive the transmission block 262 to be displaced synchronously, so that the limit end 263 will be displaced synchronously in the same direction. The guide post 265 guides the transmission block 262, and the second spring 266 resets the pressing end 261.

[0047] Specifically, such as Figure 7 As shown, a wedge surface 267 is provided at one end of the pressing end 261 away from the transmission block 262, and the wedge surface 267 faces the first retaining ring 223. It can be understood that when the autonomous pop-up mechanism 3 undergoes axial displacement on the gun body 22, the presence of the wedge surface 267 will cause the pressing end 261 to be subjected to radial pressure during the displacement of the autonomous pop-up mechanism 3, thereby ensuring that the pressing end 261 can undergo radial displacement.

[0048] like Figure 8 and Figure 9 As shown, the autonomous pop-up mechanism 3 includes an abutment ring 31, a plurality of guide rods 32 and an abutment end plate 33. The abutment ring 31 is slidably mounted on the gun body 22 and is located on the side of the second retaining ring 224 facing the gun head 23. It should be noted here that a buffer pad is provided on the side of the abutment ring 31 facing the vehicle body to avoid the elastic impact of the abutment ring 31 causing damage to the vehicle body; a plurality of guide rods 32 are evenly arranged circumferentially and fixed to the abutment ring 31, and the guide rods 32 are slidably inserted into the first retaining ring 223 and the second retaining ring 224 respectively; one end of the abutment end plate 33 abuts against the abutment plate 42, and one end of the abutment end plate 33 is elastically inserted into the guide rod 32 and hinged to the second hinge block 342; the first hinge block 341 is hinged to the end face of the guide rod 32.

[0049] It should be noted that, in the specific embodiment of the present application, according to the actual shape of the charging gun 2 , the positioning member 34 is provided at the end of at least two of the guide rods 32 to prevent the locking force formed by the positioning member 34 from being insufficient.

[0050] Among them, a third spring 321 is sleeved on the guide rod 32, one end of the third spring 321 abuts against the abutting ring 31, and the other end of the third spring 321 abuts against the second retaining ring 224. It can be understood that when the entire autonomous pop-up mechanism 3 is in a locked state, the third spring 321 is in a compressed state, so the third spring 321 mainly provides the ejection power to the autonomous pop-up mechanism 3; one end of the guide rod 32 is coaxially fixed to the limiting end block 322, and the limiting end block 322 is hinged to the first hinge block 341. It should be noted that Yes, in the specific embodiment of the present application, the limiting end block 322 can smoothly slide through the first retaining ring 223 and be limited by the second retaining ring 224, which not only ensures that the autonomous pop-up mechanism 3 will not separate from the gun body 22 when the locked state is released, but also limits the axial displacement stroke of the entire autonomous pop-up mechanism 3. At the same time, the limiting end block 322 located on the side of the pressing end 261 and the wedge-shaped surface 267 thereon are slidably matched, and a sliding cavity 323 is coaxially arranged in the guide rod 32, and a fourth spring 324 is axially embedded in the sliding cavity 323.

[0051] When the locking cam 331 is in the locked state, the locking cam 331 is in the locked state, and the locking cam 332 is in the locked state, so the first and second locking cams 331 and 332 are in the locked state.

[0052] It should be noted that the positioning member 34 is located between the abutment plate 42 and the first retaining ring 223. When the positioning member 34 expands radially, the first retaining ring 223 interferes with the movement of the autonomous pop-up mechanism 3, that is, at this time the outer diameter of the positioning member 34 is larger than the diameter of the hole on the first retaining ring 223. When the positioning member 34 expands axially, the first retaining ring 223 will not interfere with the movement of the autonomous pop-up mechanism 3, that is, at this time the outer diameter of the positioning member 34 is smaller than the diameter of the hole on the first retaining ring 223. It should be further noted that the abutment end plate 33 can slide through the first retaining ring 223, so as to avoid affecting the ejection stroke of the autonomous pop-up mechanism 3.

[0053] Specifically, such as Figure 10 As shown, the limiting assembly 41 includes a trigger rod 411 inserted into the baffle 213, and a fifth spring 412 is sleeved on the trigger rod 411. A first positioning ring 413 and a second positioning ring 414 are coaxially fixed to the trigger rod 411, wherein the first positioning ring 413 is close to the abutment plate 42, and the second positioning ring 414 is located at the end of the trigger rod 411 away from the abutment plate 42. The two ends of the fifth spring 412 are respectively abutted against the baffle 213 and the first positioning ring 413. In this way, the trigger rod 411 forms a limited insertion on the baffle 213 and forms an elastic insertion through the fifth spring 412.

[0054] It should be noted that the trigger rod 411 is in a hemispherical configuration at one end thereof that abuts against the abutment plate 42, so that the trigger rod 411 can slide toward the notch 421 when the gun tail 21 undergoes axial deflection, thereby preventing the trigger rod 411 from affecting the displacement of the abutment plate 42 toward the gun tail 21.

[0055] The following describes the use process of a new energy charging gun anti-drag charging pile according to an embodiment of the present application with reference to the accompanying drawings:

[0056] In the initial state, a stable plug-in relationship is formed between the gun tail 21 and the gun body 22, that is, at this time, the I-shaped cylinder 221 is plugged into the end ring 211, and the distance between the end of the I-shaped cylinder 221 located in the gun tail 21 and the end ring 211 is the largest at this time. The first spring 222 is in the maximum extension state at this time, and multiple elastic columns 214 are respectively plugged into one end of the I-shaped cylinder 221 located in the gun body 22, so that a relatively stable fixed connection relationship is formed between the gun tail 21 and the gun body 22. Further, at this time, the trigger rod 411 abuts against the end face of the abutment plate 42, and forces the abutment plate 42 to squeeze the abutment end plate 33, so that the distance between the abutment plate 42 and the first baffle ring 223 is kept at the most static at this time. It should be noted that the first spring 222 and the third spring The elastic design of the spring 321, the fourth spring 324, and the fifth spring 412 enables the various components on the entire charging gun 2 to maintain a stably connected and locked state, and the abutment ring 31 does not extend out of the gun body 22 at this time, that is, the third spring 321 is in a compressed state at this time, so that the two ends of the multiple first hinge blocks 341 and the second hinge blocks 342 are squeezed and thus will present a radial maximum state, that is, the first hinge block 341 and the second hinge block 342 form a semi-overlapping state as shown in the figure. At this time, the semi-overlapping state of the first hinge block 341 and the second hinge block 342 forms a locking state of the entire autonomous pop-up mechanism 3 on the gun body 22, and the user holding the handle 225 can plug the charging gun 2 into the charging port of the vehicle. During use, the charging gun 22 is not pulled out and the vehicle starts to move away. At this time, the charging gun 22 will move with the vehicle until the cable 24 applies lateral pulling force to the gun tail 21 in the opposite direction due to its length limitation. At this time, the gun tail 21 is subjected to force and changes its axial angle relative to the gun body 22, and at the same time drives the trigger rods 411 on both sides to change the same angle. In this way, the abutting end of the trigger rod 411 will slide into the notch 421, causing the abutting plate 42 to lose its abutting force. At this time, under the elastic force of the fourth spring 324, the abutting rod 331 will be forced to move in the direction away from the guide rod 32, and then the abutting end plate 33 will be displaced in the same direction. In this way, the multiple first hinge blocks 341 and the second hinge blocks 341, which were originally squeezed to form the maximum radial state, will be displaced. When the locking cam 321 is in the unlocked position, the locking cam 322 is in the unlocked position, and the locking cam 323 ...The locking state between the charging gun 2 and the vehicle charging port is released. After the abutment ring 31 touches the vehicle body, its displacement stroke has not yet ended, so it will apply a reverse force to the charging gun 2, causing the charging gun 2 to detach from the vehicle body until the limiting end block 322 is blocked by the second retaining ring 224 and stops axial displacement. This design allows the charging gun 2 to smoothly detach from the vehicle body even when subjected to lateral force. Similarly, in the specific embodiment of the present application, when the charging gun 2 is subjected to a coaxial pulling force, it is obvious that the above-mentioned detachment action can be easily achieved. When the charging gun 2 wants to restore a stable connection state, it only needs to align the multiple elastic columns 214 and plug them into the I-shaped cylinder 221.

[0057] In the related art, in the new energy charging gun anti-drag charging pile, after the charging gun 2 is ejected from the vehicle body, if it falls to the ground without protection, it is very easy to cause the charging gun 2 to be damaged, affecting the service life of the entire charging pile 1.

[0058] Example 2: According to some embodiments of this application, Figure 2 and Figure 11 As shown, the gun body 22 is coaxially sleeved with a fall protection piece 5, which includes a first triangular frame 51 coaxially sleeved on the first retaining ring 223, and a second triangular frame 52 coaxially slidably sleeved between the first retaining ring 223 and the second retaining ring 224. The first triangular frame 51 and the second triangular frame 52 are consistent in shape and size, and the first triangular frame 51 and the second triangular frame 52 are at the same angle on the gun body 22. The first triangular frame 51 and the second triangular frame 52 are both arranged in the form of regular triangles. The bottom end angles of the first triangular frame 51 and the second triangular frame 52 deviate from the central axis of the charging gun 2, and the bottom end corners of the first triangular frame 51 and the second triangular frame 52 are lower than the end of the gun tail 21 away from the gun body 22.

[0059] It should be noted that cushioning pads may be added to the corner ends of the first triangular frame 51 and the second triangular frame 52 to enhance protection against falling.

[0060] It can be seen from this that when the charging gun 2 falls to the ground, if the gun tail 21 is kept facing downward (i.e. Figure 2 At this time, the bottom ends of the first triangular frame 51 and the second triangular frame 52 touch the ground first, and under the action of the center of gravity of the entire charging gun 2, the charging gun 2 falls to the right, preventing the gun tail 21, the cable 24 connection end and the gun head 23 from being damaged by touching the ground.

[0061] A sliding ring 53 is embedded in the second triangular frame 52 , and the sliding ring 53 is slidably mounted on the gun body 22 .

[0062] Specifically, a plurality of sliders 531 are embedded in the slip ring 53 . The sliders 531 are slidably sleeved on the guide rod 32 . The outer diameter of the sliders 531 is not greater than the outer diameter of the limiting end block 322 .

[0063] Therefore, when the charging gun 2 is separated from the vehicle body, the axial displacement of the guide rod 32 will first drive the slip ring 53 and the second triangular frame 52 fixed thereon to move away from the first triangular frame 51, so that a certain distance is formed between the first triangular frame 51 and the second triangular frame 52. In this way, when the charging gun 2 falls to the ground, because the bottom corners of the first triangular frame 51 and the second triangular frame 52 are lower than the end of the gun tail 21 away from the gun body 22, the gun tail 21 and the cable 24 connection end and the gun head 23 can be prevented from being damaged by hitting the ground, and finally the charging gun 2 can be ensured to lie on its side on the ground. If the ground is wet or even wet, the charging gun 2 can be prevented from being immersed in water to a certain extent.

[0064] In the related technology, this new energy charging gun anti-drag charging pile, after the charging gun 2 falls to the ground, the existing technology mostly uses the automatic winding device installed in the direction of the charging pile 1 to drag the charging gun 2 back, and the ground conditions are complicated. First, during the retraction process, the charging gun 2 will be worn or even bumped on the ground. Once an obstacle appears and the charging gun 2 is blocked, it is very easy to cause a second dragging phenomenon between the charging gun 2 and the charging pile 1.

[0065] Example 3: According to some embodiments of this application, Figure 2 、 Figure 12 and Figure 13 As shown, two recovery guards 6 are symmetrically provided on the side of the first triangular frame 51 and the second triangular frame 52 away from each other, and the recovery guard 6 includes three L-shaped positioning plates 61. The L-shaped positioning plates 61 are evenly fixed to the end faces of the first triangular frame 51 or the second triangular frame 52 in the circumferential direction. A roller shaft 62 is elastically provided on the L-shaped positioning plates 61 along the length direction, and the roller shaft 62 extends out of the first triangular frame 51 or the second triangular frame 52 in the radial direction of the gun body 22.

[0066] Among them, multiple positioning rods 621 are set on one side of the roller shaft 62 (specifically, the roller shaft 62 is rotatably connected to the bracket, and the bracket and the positioning rod 621 are fixedly connected). The positioning rod 621 is slidably inserted into the L-shaped positioning plate 61, and a sixth spring 622 is sleeved on the positioning rod 621.

[0067] Therefore, when the charging gun 2 is separated from the vehicle body, the axial displacement of the guide rod 32 will drive the slip ring 53 and the second triangular frame 52 fixed thereon to move away from the first triangular frame 51, so that a certain distance is formed between the first triangular frame 51 and the second triangular frame 52. At the moment of falling to the ground, if the corner of the first triangular frame 51 and the second triangular frame 52 touches the ground, the cushioning pad added thereon will first cushion the falling of the charging gun 2. Secondly, when the charging gun 2 lies on its side, the moment the mixing ring 62 touches the ground, the sixth spring 622 will further play a role. The buffering effect is achieved. At this time, the rollers 62 on the ground side of the two recovery guards 6 are in contact with the ground. When the automatic reeling device in the direction of the charging pile 1 actively reels the cable 24, the charging gun 2 is retracted by the cable 24 and can slide on the ground with the help of the rollers 62, avoiding friction between the charging gun 2 and the ground and causing wear of the charging gun 2. The design of the rollers 62 can also adapt to complex ground conditions. Even if there are stones, bumps, potholes, etc. on the ground, the rollers 62 can also make the charging gun 2 move smoothly toward the charging pile 1.

[0068] It should be noted that the specific models and specifications of the charging pile 1, elastic column 214, first spring 222, gun head 23, bellows 25, second spring 266, third spring 321, fourth spring 324, fifth spring 412 and sixth spring 622 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0069] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
