Description

Technical Field

[0001] The present application relates to the technical field of suction cups, and in particular to a suction cup for a charging gun of a new energy vehicle. Background Art

[0002] New energy generally refers to renewable energy that is developed and utilized based on new technologies, including solar energy, biomass energy, wind energy, geothermal energy, wave energy, ocean current energy and tidal energy, as well as thermal circulation between the ocean surface and deep layers; in addition, there are hydrogen energy, biogas, alcohol, methanol, etc.

[0003] At present, with the development of new energy, new energy vehicles have also developed rapidly. Most new energy vehicles use electricity to drive, so when recharging, it is often necessary to recharge the car through a charging gun.

[0004] The charging guns used in existing new energy vehicles are generally directly inserted into the car's charging port to complete the charging of the car. However, the existing charging guns are sometimes not fully inserted into the charging port, resulting in unstable contact between the charging gun and the charging port, thereby affecting the charging efficiency or even making charging impossible. If the user cannot discover it in time, it will affect the charging time. Summary of the invention

[0005] Based on this, it is necessary to provide a suction cup for a new energy vehicle charging gun to address the problem that the existing charging gun is sometimes not fully inserted into the charging port, resulting in unstable contact between the charging gun and the charging port, and the user cannot discover it in time.

[0006] The present application provides a suction cup for a new energy vehicle charging gun, comprising:

[0007] A charging gun body, the charging gun body comprising a gripping portion, a processing portion and a charging portion, the gripping portion being fixedly connected to one end of the processing portion, and the charging portion being fixedly connected to the other end of the processing portion;

[0008] A suction cup assembly, the suction cup assembly comprising a turntable, a support frame, a suction cup member, a sensing rod, a reset spring and a guide rod, the turntable is rotatably connected to the tail of the processing part, one end of the support frame is rotatably connected to the turntable, the suction cup member is fixedly connected to the other end of the support frame, the sensing rod is slidably connected to the head of the processing part, one end of the guide rod abuts against one end of the sensing rod, the other end of the guide rod is fixedly connected to one end of the reset spring, and the other end of the reset spring is fixedly connected to the inner wall of the processing part;

[0009] A spray assembly, wherein the spray assembly is arranged in the processing part, and the spray assembly includes a storage chamber, a water pump, a sensor and a water spray outlet. The storage chamber is opened in the processing part, the water inlet of the water pump is connected with the storage chamber, the water outlet of the water pump is connected with the water spray outlet, the water spray outlet is opened on the wall surface of the processing part, the sensor is fixedly connected to the processing part, and the sensor is against the sensing rod.

[0010] The present application relates to a suction cup for a new energy vehicle charging gun. After the charging part is inserted into the charging port of the vehicle, the sensing rod shrinks toward the inside of the processing part, thereby pushing the guide rod to move in the direction of the compression return spring, and then adjusting the length of the support frame and the angle of the suction cup member so that the suction cup member is adsorbed on the surface of the vehicle. The suction cup member increases the stability of the connection between the charging gun body and the vehicle. Along with the movement of the sensing rod, the pressure detected by the sensor gradually increases. When the pressure detected by the sensor reaches a threshold, the water pump is started, and water is sprayed to the suction cup member through the water nozzle, thereby increasing the adsorption force of the suction cup member, making the connection between the charging gun body and the vehicle tighter. Since both the support frame and the water pump require the sensing rod to reach a certain position before they can be started, the user can judge whether the charging gun body is tightly connected to the vehicle by the working status of the support frame and the water pump, so as to ensure the normal operation of the charging gun body.

[0024] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0025] The present application provides a suction cup for a new energy vehicle charging gun. It should be noted that the suction cup for a new energy vehicle charging gun provided in the present application is applicable to any type of charging gun.

[0026] like Figures 1 to 6 As shown, in one embodiment of the present application, the suction cup for the new energy vehicle charging gun includes a charging gun body 100, a suction cup assembly 200 and a spray assembly 300.

[0027] The charging gun body 100 includes a gripping portion 101, a processing portion 102 and a charging portion 103, wherein the gripping portion 101 is fixedly connected to one end of the processing portion 102, and the charging portion 103 is fixedly connected to the other end of the processing portion 102. The suction cup assembly 200 includes a rotating disk 201, a support frame 202, a suction cup member 203, a sensing rod 204, a reset spring 205 and a guide rod 206, wherein the rotating disk 201 is rotatably connected to the tail of the processing portion 102, one end of the support frame 202 is rotatably connected to the rotating disk 201, the suction cup member 203 is fixedly connected to the other end of the support frame 202, the sensing rod 204 is slidably connected to the head of the processing portion 102, one end of the guide rod 206 abuts against one end of the sensing rod 204, the other end of the guide rod 206 is fixedly connected to one end of the reset spring 205, and the other end of the reset spring 205 is fixedly connected to the inner wall of the processing portion 102. The spray assembly 300 is arranged in the processing part 102, and the spray assembly 300 includes a storage chamber 301, a water pump 302, a sensor 303 and a water spray port 304. The storage chamber 301 is opened in the processing part 102, the water inlet of the water pump 302 is connected with the storage chamber 301, the water outlet of the water pump 302 is connected with the water spray port 304, and the water spray port 304 is opened on the wall of the processing part 102. The sensor 303 is fixedly connected to the processing part 102, and the sensor 303 is against the sensing rod 204.

[0028] In this embodiment, after the charging part 103 is inserted into the charging port of the vehicle, the sensing rod 204 contracts toward the inside of the processing part 102, thereby pushing the guide rod 206 to move in the direction of the compression return spring 205, and then adjusting the length of the support frame 202 and the angle of the suction cup 203 so that the suction cup 203 is adsorbed on the surface of the vehicle, and the stability of the connection between the charging gun body 100 and the vehicle is increased by the suction cup 203. With the movement of the sensing rod 204, the pressure detected by the sensor 303 gradually increases. When the pressure detected by the sensor 303 reaches the threshold, the water pump 302 is started, and water is sprayed to the suction cup 203 through the water spray port 304, thereby increasing the adsorption force of the suction cup 203, so that the connection between the charging gun body 100 and the vehicle is tighter. Since both the support frame 202 and the water pump 302 need the sensing rod 204 to reach a certain position before they can be started, the user can judge whether the charging gun body 100 is tightly connected to the vehicle by the working status of the support frame 202 and the water pump 302, so as to ensure the normal operation of the charging gun body 100.

[0029] like Figure 3 As shown, in one embodiment of the present application, the support frame 202 includes a fixed portion 209 and a sliding portion 210 , one end of the fixed portion 209 is rotatably connected to the turntable 201 , and the sliding portion 210 is slidably connected to the other end of the fixed portion 209 .

[0030] Specifically, when the sliding portion 210 is completely retracted into the fixing portion 209 , the suction cup member 203 is located outside the fixing portion 209 .

[0031] In this embodiment, since the specifications of the opening covers of the charging ports of different vehicles are not uniform, in order to enable the suction cup body 207 to adapt to vehicles of different specifications, the support frame 202 is set to be adjustable in length so that the support frame 202 can be applied to more types of vehicles.

[0032] When the diameter of the opening cover of the vehicle charging port is large, the sliding portion 210 can be pulled out from the fixing portion 209, thereby increasing the total length of the support frame 202, so that the suction cup body 207 can be adsorbed on the area outside the vehicle opening cover.

[0033] When the diameter of the opening cover of the vehicle charging port is small, the sliding portion 210 can be retracted in the fixing portion 209 to shorten the total length of the support frame 202 so that the suction cup body 207 is adsorbed on the area outside the vehicle opening cover.

[0034] like Figure 5 As shown, in one embodiment of the present application, the suction cup member 203 includes a suction cup body 207 and a rotating shaft 208 , the suction cup body 207 is fixedly connected to the rotating shaft 208 , and the rotating shaft 208 is rotatably connected to one end of the sliding portion 210 .

[0035] Optionally, in order to increase the suction force of the suction cup member 204, a plurality of suction cup bodies 207 may be provided on the rotating shaft 208 at the same time, thereby increasing the total suction force and making the connection between the charging gun and the vehicle more stable.

[0036] Specifically, the bottom surface of the storage slot 211 is also provided with a suction cup slot for storing the suction cup body 207 , so that when the support frame 202 is stored in the storage slot 211 , the suction cup body 207 can be stored in the suction cup slot to prevent external dust from being adsorbed on the surface of the suction cup body 207 .

[0037] In this embodiment, after the charging part 103 of the charging gun is inserted into the charging port of the vehicle, the support frame 202 can be opened and the suction cup body 207 can be adsorbed on the surface of the vehicle, thereby improving the stability of the connection between the charging gun and the vehicle.

[0038] Since the opening angle of the support frame 202 is adjustable, the angle of the suction cup body 207 can be adjusted by adjusting the rotating shaft 208, so that the suction cup body 207 can always remain parallel to the contact surface of the vehicle, thereby making the suction cup body 207 fit better with the vehicle, and ultimately improving the stability of the connection between the suction cup body 207 and the vehicle.

[0039] like Figure 2As shown, in one embodiment of the present application, two support frames 202 are provided, and the two support frames 202 are symmetrically arranged about the center of the turntable 201, and storage grooves 211 are provided on the top surface of the processing part 102 and the bottom surface of the processing part 102. When the support frames 202 are idle, the two support frames 202 are fixedly connected to the storage grooves 211 on the top surface of the processing part 102 and the storage grooves 211 on the bottom surface of the processing part 102, respectively.

[0040] Optionally, the support frames 202 can also be set to other numbers. For example, when the support frames 202 are set to 4, the 4 support frames 202 can be arranged on the turntable 201 at equal intervals. The more support frames 202 are set, the more angles the charging gun can be fixed at the same time, but the corresponding cost will also increase.

[0041] In this embodiment, the upper and lower support frames 202 are used to provide support force to the support frame 202 from the upper and lower sides respectively, thereby increasing the support points of the charging gun and the vehicle, so that the support points of the charging gun and the vehicle are increased from the charging part 103-vehicle support point to the charging part 103-vehicle, the upper support frame 202-vehicle and the lower support frame 202-vehicle. Three support points make the connection between the charging gun and the vehicle more stable.

[0042] like Figure 4 As shown, in one embodiment of the present application, the suction cup assembly 200 also includes a connecting member 400, and the connecting member 400 includes a connecting buckle 402 and a fixing buckle 401, the fixing buckle 401 is fixedly connected to the bottom surface of the storage slot 211, and the connecting buckle 402 is fixedly connected to the bottom surface of the sliding part 210, and when the support frame 202 is received in the storage slot 211, the connecting buckle 402 is clamped to the fixing buckle 401.

[0043] In this embodiment, the position of the support frame 202 is fixed by the connecting member 400 to prevent the support frame 202 from falling out of the storage slot 211 .

[0044] When the charging gun is connected to the vehicle, the sensing rod 204 at one end of the processing part 102 will be gradually retracted into the interior of the processing part 102, thereby squeezing the guide rod 206, causing the guide rod 206 to move in the direction of compressing the return spring 205. During this process, the sensing rod 204 will contact the sensor 303 and continuously squeeze the sensor 303, so that the sensor 303 detects pressure.

[0045] When disconnecting the charging gun from the vehicle, the charging gun is pulled out of the charging port of the vehicle. Since the sensing rod 204 loses pressure, the guide rod 206 is pushed toward the initial position of the guide rod 206 under the action of the return spring 205, and the sensing rod 204 is also pushed back to the initial position until the guide rod 206 returns to the initial position. In this process, since the sensing rod 204 gradually moves away from the sensor 303, the pressure detected by the sensor 303 gradually decreases until it approaches 0.

[0046] When the support frame 202 is received in the storage slot 211 , the sliding portion 210 is moved to move outward from the fixing portion 209 , so that the connecting buckle 402 at the bottom of the sliding portion 210 is engaged in the fixing buckle 401 , thereby preventing the support frame 202 from falling out of the storage slot 211 .

[0047] When the support frame 202 is needed, the sliding portion 210 is moved to shrink into the fixing portion 209 , thereby disconnecting the connection buckle 402 from the fixing buckle 401 , and the support frame 202 can be removed from the storage slot 211 .

[0048] like Figure 4 As shown, in one embodiment of the present application, the connecting buckle 402 is L-shaped.

[0049] In this embodiment, the connecting buckle 402 is inserted into the fixing buckle 401, thereby completing the fixed connection between the connecting buckle 402 and the fixing buckle 401.

[0050] like Figure 1 As shown, in one embodiment of the present application, the turntable 201 is configured to be annular, and the inner diameter of the turntable 201 is equal to the outer diameter of the processing part 102 .

[0051] In this embodiment, since the orientations of the opening covers of the charging ports of different vehicles are different, some opening covers are opened upwards and some opening covers are opened to the right, which will affect the opening degree of the support frame 202, making it difficult for the suction cup body 207 to be completely adsorbed on the surface of the vehicle, which will cause the connection between the charging gun body 100 and the vehicle to be unstable.

[0052] Therefore, a turntable 201 is provided. When the opening of the support frame 202 is affected by the opening cover, the turntable 201 can be rotated to adjust the angle of the support frame 202 so that the support frame 202 avoids the influence of the opening cover and the suction cup body 207 is adsorbed on the vehicle surface.

[0053] like Figure 6As shown, in one embodiment of the present application, the sensor 303 includes a detection end 303b and a fixed end 303a, one end of the detection end 303b is fixedly connected to one end of the fixed end 303a, and the other end of the detection end 303b abuts against one end of the sensing rod 204.

[0054] Specifically, the sensor 303 is a pressure sensor 303 .

[0055] In this embodiment, the pressure between the sensing rod 204 and the sensor 303 is detected by the sensor 303. When the pressure detected by the sensor 303 reaches a certain value, the water pump 302 is started. The water pump 302 draws water from the storage chamber 301 and sprays the water onto the suction cup body 207 through the spray buckle, thereby increasing the suction force of the suction cup body 207.

[0056] like Figure 2 As shown, in one embodiment of the present application, the spray assembly 300 further includes a controller 305 , the controller 305 is fixedly connected to the processing unit 102 , the controller 305 is electrically connected to the water pump 302 , and the controller 305 is communicatively connected to the sensor 303 .

[0057] Specifically, the controller 305 may set a single start-up duration for the water pump 302 . For example, the working time of the water pump 302 is 10 seconds after each start-up, that is, the water pump 302 will spray water for 10 seconds at a time.

[0058] In this embodiment, when the sensing rod 204 is moved toward the inside of the processing part 102 under pressure, it will contact the sensor 303, thereby squeezing the sensor 303. As the sensing rod 204 squeezes the sensor 303, the sensor 303 transmits the detected pressure signal to the controller 305. After receiving the signal from the sensor 303, the controller 305 starts the water pump 302, thereby completing the cleaning of the suction cup 203.

[0059] like Figure 1 As shown, in one embodiment of the present application, a plurality of water spray outlets 304 are provided, and the plurality of water spray outlets 304 are circumferentially arranged around the center of the bottom surface of the processing portion 102 .

[0060] In this embodiment, since the support frame 202 and the suction cup member 203 may be in different positions as the turntable 201 rotates, a plurality of water spraying ports 304 are provided to ensure that water can be sprayed onto the suction cup member 203 regardless of the position of the suction cup member 203 .

[0061] The technical features of the above-described embodiments may be arbitrarily combined, and the execution order of the method steps is not limited. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
