Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle charging, and in particular to a new energy vehicle charging gun capable of dissipating heat. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source. Existing new energy vehicles mostly use electricity as a driving energy source. The car charging gun is a type of electric vehicle charging interface, which is mainly used to connect charging stations and electric vehicles to realize the function of transmitting electricity from the power source to the car battery.

[0003] During the charging process of electric vehicles, the charging gun generates a lot of heat. If this heat is not dissipated in time, it will cause the equipment to overheat, thereby affecting the charging efficiency and safety. The prior art dissipates heat from the charging gun through liquid cooling, air cooling, etc. Among them, air cooling technology is widely used due to its technical difficulty and low production cost. For example, the patent with prior art announcement number CN117284119A discloses a new energy vehicle intelligent charging gun, which can realize air circulation through the heat dissipation holes at the bottom of the charging gun body, and can cooperate with an electronically controlled fan to achieve better heat dissipation. The electronically controlled fan exhausts air outward to remove the hot air inside the charging gun body.

[0004] However, the prior art still has the following defects: there are electrical components inside the charging gun. When the inside of the charging gun is connected to the outside world, in harsh environments, dust, moisture, salt spray, etc. in the outside air are easily sucked into the charging gun, causing damage to the electrical components and even causing serious safety accidents to the charged car. Summary of the invention

[0005] In view of the problem that the traditional air-cooling heat dissipation method in the prior art is difficult to prevent external dust, moisture, salt spray and other substances from entering the charging gun and causing damage to electrical components, a new energy vehicle charging gun with heat dissipation is proposed.

[0006] The purpose is to use the heat conduction plate to transfer the internal heat of the charging gun to the outside while the heat exchange plate rotates to improve the heat exchange efficiency and effectively prevent foreign matter from entering the charging gun.

[0007] The technical solution of the present invention is a new energy vehicle charging gun capable of dissipating heat, comprising a charging gun body, the charging gun body comprising a shell, a handle, a cable, an anti-drop sleeve, a plug, and a heat dissipation module arranged on the shell, the heat dissipation module comprising a heat conduction mechanism installed on the shell, and an exhaust assembly installed at one end of the heat conduction mechanism, and also comprising a heat exchange assembly installed on the heat conduction mechanism; The heat conduction mechanism comprises a protective shell fixedly arranged on the outer side of the shell, a plurality of heat conduction plates are evenly distributed on the inner side of the protective shell, the heat conduction plates are connected and fixed to the shell, and the heat conduction plates extend into the shell; The exhaust assembly includes a fan blade rotatably arranged at one end of the protective shell, one side of the fan blade is provided with a motor with a transmission connection, and the motor is installed in the handle; The heat exchange assembly includes a driving member installed on the inner side of the protective shell, and a plurality of heat exchange plates are transmission-connected to the driving member, and the heat exchange plates are rotationally connected to the heat conducting plates.

[0008] By adopting the above technical solution, two adjacent heat conduction plates cooperate with the shell and the protective shell to form a heat dissipation duct. The heat conduction plate can transfer the heat in the charging gun body to the heat dissipation duct. The fan blades are driven by the motor to rotate to generate rapid air flow in the heat dissipation duct. The flowing air contacts the part of the heat conduction plate located outside the shell, thereby bringing out the heat. At the same time, the driving part can drive the heat exchange plate to rotate, so that the part of the heat exchange plate located in the shell is turned to the heat dissipation duct, thereby dissipating the heat more quickly, thereby achieving air cooling and preventing foreign matter from entering the shell.

[0009] Furthermore, a protective net 1 is fixedly connected inside one end of the protective shell, a connecting ring is provided inside the other end of the protective shell, and a protective net 2 is fixedly connected between the connecting ring and the protective shell.

[0010] By adopting the above technical solution, the connecting ring is abutted against one end of the shell, and the second protective net and the first protective net respectively protect the air inlet and outlet ends of the heat dissipation air duct to prevent foreign matter from entering the protective shell.

[0011] Furthermore, the fan blades include two annular plates, a plurality of blades are evenly distributed between the two annular plates, the inner annular plate is sleeved on a connecting ring, and a plurality of rollers are rotatably connected to the connecting ring, and the rollers are in rolling contact with the inner annular plate.

[0012] By adopting the above technical solution, the inner annular plate is rollingly connected to the roller so that the fan blades are set at the air inlet end of the heat dissipation duct. When the motor drives the fan blades to rotate, the oblique rotation of the blades pushes the outside air to flow quickly into the heat dissipation duct, thereby taking away the heat on the heat conduction plate.

[0013] Furthermore, the output end of the motor is fixedly connected with a driving gear, the fan blade is fixedly connected with a gear ring, and the driving gear is meshingly connected with the gear ring; The handle is provided with a cavity one, and the motor is fixedly installed in the cavity one.

[0014] By adopting the above technical solution, the motor is arranged in the cavity of the handle, which can avoid the motor taking up extra space and improve the overall appearance. When the motor drives the driving gear to rotate, the driving gear cooperates with the gear ring to drive the fan blades to rotate.

[0015] Furthermore, the driving member includes an arc-shaped rod arranged in the protective shell, a plurality of electric push rods are fixedly connected to the arc-shaped rod, the electric push rods are fixedly installed on the protective shell, and a plurality of racks are fixedly connected to the arc-shaped rod, the racks are slidably arranged in the heat conduction plate, and the racks are used to drive the heat exchange plate to rotate.

[0016] By adopting the above technical solution, each electric push rod is synchronously extended and retracted to drive the arc rod to translate, and the arc rod drives all the racks to move synchronously, so that the rack can drive the heat exchange plate to rotate. Half of the heat exchange plate is arranged in the heat dissipation duct, and the other half is arranged in the shell. Each time the heat exchange plate rotates half a circle, the part of the heat exchange plate located on the inner side of the shell and the part located in the heat dissipation duct can be exchanged, so that the high-temperature part absorbed in the shell is turned to the heat dissipation duct for heat dissipation, and the part that has completed heat dissipation enters the shell to absorb heat again, saving the heat transfer time of the heat exchange plate and accelerating the heat exchange efficiency.

[0017] Furthermore, the heat conducting plate is provided with a plurality of annular holes, the heat exchange plate is rotatably disposed in the annular holes, the heat exchange plate is provided with annular tooth grooves, and the annular tooth grooves are meshedly connected with the rack.

[0018] By adopting the above technical solution, when the rack moves, it engages with the annular tooth groove to drive the rotation of the heat exchange plate, so that when the heat exchange plate completes a half circle of rotation, the heat exchange plate can exchange positions in the heat dissipation duct and the shell, thereby improving the heat exchange efficiency.

[0019] Furthermore, two heat exchange chambers are provided in the heat exchange plate, and a wind guiding inclined surface is provided on one side of the heat exchange chamber of the heat conductive plate, and the wind guiding inclined surface is communicated with the annular hole.

[0020] By adopting the above technical solution, the through holes of the two heat exchange chambers are axially symmetrically arranged, and part of the heat in the shell can enter the heat exchange chamber. When the heat exchange plate rotates, the heat exchange chamber filled with heat is located in the heat dissipation duct. Under the action of the flowing air, the heat in the heat exchange chamber is quickly dissipated, so that the temperature is the same as the normal temperature outside. When the heat exchange plate rotates again, normal temperature air can be brought into the shell and mixed with the heat inside the shell, thereby reducing the heat inside the shell, thereby further improving the heat dissipation effect inside the shell.

[0021] Furthermore, a plurality of air guide plates are fixedly connected inside the protective shell, the air guide plates are arranged between two adjacent heat conduction plates, and the air guide plates are in a conical structure.

[0022] By adopting the above technical solution, the air guide plate reduces the flow space of the heat dissipation duct, and the air in the heat dissipation duct has its flow velocity increased under the action of the inclined surface of the air guide plate, and the flowing air is more effectively in contact with the heat conduction plate and the heat exchange plate, further improving the heat dissipation effect.

[0023] Furthermore, a second cavity is provided on the handle, and an anti-detachment component is installed in the second cavity. The anti-detachment component includes a connecting rod rotatably connected to the second cavity, one end of the connecting rod passes through the handle and is fixedly connected to an anti-detachment block, and the other end of the connecting rod is fixedly connected to a pressing handle, and a spring is elastically connected between the pressing handle and the second cavity.

[0024] By adopting the above technical solution, after the charging gun body is plugged into the car charging port, the anti-disengagement block is engaged with the anti-disengagement groove of the car charging port, which can prevent the charging gun body from being pulled out of the car charging port and improve the connection stability. By pressing the pressing handle downward to drive the connecting rod to rotate, the anti-disengagement block can be cancelled from the anti-disengagement groove, and the charging gun body can be pulled out from the car charging port.

[0025] Compared with the prior art, the present invention has the following beneficial effects: 1. The heat in the shell is directed to the heat dissipation duct through the heat conduction plate. The rotation of the fan blades generates rapid air flow in the heat dissipation duct, so that the heat on the heat conduction plate is discharged outward. At the same time, when the heat exchange plate rotates intermittently, the high-temperature part in the shell can be directly rotated to the heat dissipation duct for cooling, thereby saving heat transfer time. At the same time, the normal temperature part of the heat exchange plate enters the shell again to absorb heat, so that effective heat dissipation can be achieved while preventing foreign objects from entering the shell, ensuring the safety of the charging gun.

[0026] 2. By setting two heat exchange chambers in the heat exchange plate, when the heat exchange plate rotates, the outside normal temperature air enters the shell through the heat exchange chamber to neutralize the heat. At the same time, the flowing air cooperates with the wind guide slope to blow and cool the heat exchange chamber part containing heat. The above reciprocating cycle can further improve the heat dissipation effect inside the shell.

[0027] 3. The air flow space of the heat dissipation duct is reduced by setting the air guide plate. The air in the heat dissipation duct has its flow velocity increased by the inclined surface of the air guide plate, and the flowing air is more effectively in contact with the heat conduction plate and the heat exchange plate, further improving the heat dissipation effect.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] Example 1, reference Figure 1-Figure 9 , which is the first embodiment of the present invention, provides a new energy vehicle charging gun capable of heat dissipation, including a charging gun body 1, the charging gun body 1 including a shell 11, a handle 12, a cable 13, an anti-drop sleeve 14, and a plug 15, and also includes a heat dissipation module arranged on the shell 11, the heat dissipation module includes a heat conduction mechanism 2 installed on the shell 11, and an exhaust assembly 3 installed at one end of the heat conduction mechanism 2, and also includes a heat exchange assembly 4 installed on the heat conduction mechanism 2; the heat conduction mechanism 2 includes a protective shell 21 fixedly arranged on the outside of the shell 11, and a plurality of heat conduction plates 22 are evenly distributed on the inner side of the protective shell 21, the heat conduction plates 22 are connected and fixed to the shell 11, and the heat conduction plates 22 extend into the shell 11; the exhaust assembly 3 includes a fan blade rotatably arranged at one end of the protective shell 21, and a motor 33 with a transmission connection is provided on one side of the fan blade, and the motor 33 is installed in the handle 12; the heat exchange assembly 4 includes a driving member installed on the inner side of the protective shell 21, and a plurality of heat exchange plates 44 are transmission-connected to the driving member, and the heat exchange plate 44 is rotatably connected to the heat conduction plate 22.

[0032] Specifically, two adjacent heat conducting plates 22 cooperate with the shell 11 and the protective shell 21 to form a heat dissipation duct. The heat conducting plate 22 can transfer the heat in the charging gun body 1 to the heat dissipation duct. The fan blades are driven by the motor 33 to rotate to generate rapid air flow in the heat dissipation duct. The flowing air contacts the part of the heat conducting plate 22 located outside the shell 11, thereby bringing out the heat. At the same time, the driving part can drive the heat exchange plate 44 to rotate, so that the part of the heat exchange plate 44 located in the shell 11 is turned to the heat dissipation duct, thereby dissipating the heat more quickly, thereby achieving air cooling and preventing foreign matter from entering the shell 11.

[0033] In order to ensure that the heat in the shell 11 is quickly transferred to the outside, the heat conducting plate 22 and the heat exchanging plate 44 are made of metal materials (copper, aluminum, etc.) with excellent thermal conductivity.

[0034] Reference Figure 3 , Figure 5 A protective net 1 23 is fixedly connected inside one end of the protective shell 21 , a connecting ring 24 is provided inside the other end of the protective shell 21 , and a protective net 25 is fixedly connected between the connecting ring 24 and the protective shell 21 .

[0035] Specifically, the connecting ring 24 abuts against one end of the shell 11 , and the second protective net 25 and the first protective net 23 respectively protect the air inlet and the air outlet of the heat dissipation air duct to prevent foreign matter from entering the protective shell 21 .

[0036] Reference Figure 5 , Figure 6 The fan blades include two annular plates 31, and a plurality of blades 32 are evenly distributed between the two annular plates 31. The inner annular plate 31 is sleeved on the connecting ring 24, and a plurality of rollers 26 are rotatably connected to the connecting ring 24, and the rollers 26 are in rolling contact with the inner annular plate 31.

[0037] Specifically, the inner annular plate 31 is rollingly connected to the roller shaft 26 so that the fan blades are arranged at the air inlet end of the heat dissipation duct. When the motor 33 drives the fan blades to rotate, the oblique blades 32 rotate to push the outside air to flow quickly into the heat dissipation duct, thereby taking away the heat on the heat conduction plate 22.

[0038] Reference Figure 7 The output end of the motor 33 is fixedly connected with a driving gear 34, and the fan blade is fixedly connected with a ring gear 35, and the driving gear 34 is meshed with the ring gear 35; a cavity 1 is opened on the handle 12, and the motor 33 is fixedly installed in the cavity 1.

[0039] Specifically, the motor 33 is disposed in a cavity 1 of the handle 12, so that the motor 33 does not occupy extra space and improves the overall appearance. When the motor 33 drives the driving gear 34 to rotate, the driving gear 34 cooperates with the gear ring 35 to drive the fan blades to rotate.

[0040] Reference Figure 3 , Figure 8 , Fig. 9 The driving member includes an arc rod 41 disposed in the protective shell 21, and a plurality of electric push rods 42 are fixedly connected to the arc rod 41. The electric push rods 42 are fixedly installed on the protective shell 21, and a plurality of racks 43 are fixedly connected to the arc rod 41. The racks 43 are slidably disposed in the heat conduction plate 22, and the racks 43 are used to drive the heat exchange plate 44 to rotate.

[0041] Specifically, each electric push rod 42 synchronously extends and retracts to drive the arc rod 41 to translate, and the arc rod 41 drives all the racks 43 to move synchronously, so that the racks 43 can drive the heat exchange plate 44 to rotate. Half of the heat exchange plate 44 is arranged in the heat dissipation duct, and the other half is arranged in the shell 11. Each time the heat exchange plate 44 rotates half a circle, the part of the heat exchange plate 44 located on the inner side of the shell 11 and the part located in the heat dissipation duct can be exchanged, so that the high-temperature part absorbed in the shell 11 is transferred to the heat dissipation duct for heat dissipation, and the part that has completed heat dissipation enters the shell 11 to absorb heat again, thereby saving the heat transfer time of the heat exchange plate 44 and accelerating the heat exchange efficiency.

[0042] Reference Fig. 9 A plurality of annular holes 29 are formed on the heat conducting plate 22 , and a heat exchanging plate 44 is rotatably disposed in the annular holes 29 . An annular tooth groove 45 is formed on the heat exchanging plate 44 , and the annular tooth groove 45 is meshedly connected with the rack 43 .

[0043] Specifically, when the rack 43 moves, it engages with the annular tooth groove 45 to drive the heat exchange plate 44 to rotate, so that when the heat exchange plate 44 completes a half circle of rotation, the heat exchange plate 44 exchanges positions in the heat dissipation duct and the shell 11, thereby improving heat exchange efficiency.

[0044] Among them, a convex ring is fixed in the annular hole 29, and the annular tooth groove 45 of the heat exchange plate 44 is arranged in a groove shape. The annular tooth groove 45 is engaged with the convex ring, and the upper and lower sides of the heat exchange plate 44 are in friction contact with the heat conducting plate 22, so that the heat exchange plate 44 is rotatably arranged on the heat conducting plate 22, and at the same time, the sealing between the heat conducting plate 22 and the heat exchange plate 44 is ensured to prevent moisture, salt spray, etc. from entering the shell 11, and heat transfer can be carried out between the heat conducting plate 22 and the heat exchange plate 44, thereby improving the thermal conductivity efficiency of the heat exchange plate 44.

[0045] In actual work, a temperature sensor is installed in the shell 11, and the temperature sensor is connected to the motor 33 and the electric push rod 42 through a control module. The internal temperature of the shell 11 is monitored by the temperature sensor, and the opening and closing of the motor 33 and the electric push rod 42 are controlled by the control module. The specific principle is as follows: when the temperature inside the shell 11 is close to the outside temperature, only the heat transfer plate 22 is used to transfer the internal heat of the shell 11 to the outside for passive heat dissipation. When the temperature inside the shell 11 is higher than the normal temperature and lower than the set threshold, the motor 33 starts to drive the fan blades to rotate, and the heat transfer plate 22 is dissipated by fast-flowing air for active heat dissipation. When the temperature inside the shell 11 is higher than the set threshold, the motor 33 starts and the electric push rod 42 moves intermittently, causing the heat exchange plate 44 to rotate intermittently, thereby improving the efficiency of heat dissipation in the shell 11.

[0046] Example 2, reference Fig.10 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that two heat exchange chambers 46 are provided in the heat exchange plate 44, and the heat conductive plate 22 is provided with an air guiding slope 27 on one side of the heat exchange chamber 46, and the air guiding slope 27 is connected to the annular hole 29.

[0047] Specifically, the through holes of the two heat exchange chambers 46 are axially symmetrically arranged, and part of the heat in the shell 11 can enter the heat exchange chamber 46. When the heat exchange plate 44 rotates, the heat exchange chamber 46 filled with heat is located in the heat dissipation duct. Under the action of the flowing air, the heat in the heat exchange chamber 46 is quickly dissipated, so that the temperature is the same as the normal temperature of the outside. When the heat exchange plate 44 rotates again, normal temperature air can be brought into the shell 11 and mixed with the heat inside the shell 11, thereby reducing the heat inside the shell 11, thereby further improving the heat dissipation effect inside the shell 11.

[0048] Among them, the through hole of the heat exchange chamber 46 located in the heat dissipation duct is facing the direction of air flow, so that the flowing air can bring out the heat in the heat exchange chamber 46 when passing through the air guide slope 27, and at the same time prevent the outside air from directly entering the heat exchange chamber 46, thereby preventing dust, moisture, salt spray, etc. in the outside air from entering the shell 11, ensuring the safety of the electrical components in the shell 11.

[0049] Reference Figure 3 , Fig. 9 A plurality of air guide plates 28 are fixedly connected in the protective shell 21 . The air guide plates 28 are arranged between two adjacent heat conducting plates 22 , and the air guide plates 28 are in a conical structure.

[0050] Specifically, the air guide plate 28 reduces the flow space of the heat dissipation air duct, and the air in the heat dissipation air duct is increased in velocity by the inclined surface of the air guide plate 28, and the flowing air is more effectively in contact with the heat conduction plate 22 and the heat exchange plate 44, further improving the heat dissipation effect. The rest of the structure is the same as that of the first embodiment.

[0051] Example 3, reference Figure 1 , Figure 7 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a cavity 2 is opened on the handle 12, and an anti-slip assembly 5 is installed in the cavity 2. The anti-slip assembly 5 includes a connecting rod 51 rotatably connected to the cavity 2, one end of the connecting rod 51 passes through the handle 12 and is fixedly connected to an anti-slip block 52, and the other end of the connecting rod 51 is fixedly connected to a pressing handle 53, and a spring 54 is elastically connected between the pressing handle 53 and the cavity 2.

[0052] Specifically, after the charging gun body 1 is plugged into the car charging port, the anti-dropout block 52 is engaged with the anti-dropout groove of the car charging port, which can prevent the charging gun body 1 from being pulled out of the car charging port and improve the connection stability. By pressing the pressing handle 53 downward to drive the connecting rod 51 to rotate, the anti-dropout block 52 can cancel the engagement with the anti-dropout groove, and the charging gun body 1 can be pulled out of the car charging port. The rest of the structure is the same as that of Example 2.

[0053] In summary, the working principle of the present invention is as follows: when the charging gun body 1 is working, the heat generated inside is absorbed by the heat conducting plate 22 and transferred to the heat dissipation duct, the motor 33 drives the blade 32 to rotate, so that the rapid air flow generated in the heat dissipation duct causes the flowing air to take out the heat on the heat conducting plate 22, and at the same time, each electric push rod 42 synchronously extends and retracts to drive the arc rod 41 to translate, the rack 43 engages with the annular tooth groove 45 to drive the heat exchange plate 44 to rotate intermittently, so that the parts of the heat exchange plate 44 located in the shell 11 and the heat dissipation duct are exchanged, and the high-temperature part of the heat exchange plate 44 quickly dissipates heat under the flowing air in the heat dissipation duct, and at the same time, the heat exchange plate 44 at room temperature enters the shell 11 to absorb heat, and at the same time, when the heat exchange cavity 46 containing the internal heat of the shell 11 faces the heat dissipation duct, the flowing air causes the heat in the heat exchange cavity 46 to dissipate quickly, and then the air temperature of the heat exchange cavity 46 is equal to that of the outside world and then enters the shell 11 again to mix, so as to effectively dissipate the heat in the shell 11.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
