Description

Technical Field

[0001] The present invention belongs to the technical field of charging harnesses, and in particular relates to a corrosion-resistant flame-retardant charging harness for new energy vehicles. Background Art

[0002] The anti-corrosion flame-retardant charging harness for new energy vehicles is a high-performance charging harness designed specifically for new energy vehicles. Its core goal is to solve the two major challenges faced by traditional harnesses in complex environments: environmental corrosion and fire risks.

[0003] However, the conventional device still has the following problems when used: The patent application publication number is CN215552601U, which discloses a high-voltage charging harness for new energy vehicles. A corrugated tube is arranged on the outer wall of the high-voltage charging harness of the vehicle, and the internal structure of the charging harness can be shockproofed and its surface can be protected from damage. An extrusion spring is arranged between the outer electrostatic shielding layer and the outer insulating layer, so that the harness can be prevented from extrusion by the extrusion spring, thereby protecting the high-voltage harness core and the low-voltage harness core in the outer insulating layer, thereby preventing the wires of the charging harness from leaking, thereby reducing safety hazards in the vehicle.

[0004] In the prior art, a protective sleeve and copper wire are provided inside the wiring harness body to protect the charging wiring harness body, but the plugs at both ends of the wiring harness are not protected.

[0032] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] For example, see Figures 1 to 14 The present invention provides a corrosion-resistant flame-retardant charging harness technical solution for new energy vehicles: comprising a charging harness body 1, an outer wall of one end of the charging harness body 1 is fixedly connected with a plug 11, an inner wall of the charging harness body 1 is fixedly connected with a protective cover 12, an inner wall of the protective cover 12 is fixedly connected with a wire mesh 13, an outer wall of the charging harness body 1 is fixedly connected with a telescopic shell 2, an outer wall of one end of the telescopic shell 2 is fixedly connected with a fixed cover 22, an inner wall of the fixed cover 22 is in active contact with an outer wall of the charging harness body 1, an outer wall on one side of the fixed cover 22 is fixedly connected with a flame-retardant cover 21, an inner part of the flame-retardant cover 21 is slidably connected with an outer wall of the plug 11, an outer wall on the other side of the fixed cover 22 is fixedly connected with a U-shaped fixing frame 3, and the U-shaped fixing frame 3 A reduction wheel 31 is provided on the inner wall of one side, and a gear seat 32 is fixedly connected to the outer wall of the top of the charging harness body 1, and the outer wall of the top of the gear seat 32 is meshed with the outer wall of the reduction wheel 31. The inner wall of one side of the U-shaped fixing frame 3 is rotatably connected to the rotating shaft 33, and the outer wall of the rotating shaft 33 is fixedly connected to the reduction wheel 31. The inside of the gear seat 32 is fixedly connected to an elastic block 323, and the outer wall of the top of the elastic block 323 is fixedly connected to a tooth 321, and the outer wall of the bottom of the tooth 321 is slidably connected to the inside of the gear seat 32. The outer wall of the other side of the fixing sleeve 22 is fixedly connected to a guide plate 322, and the outer wall of the bottom of the guide plate 322 is in active contact with the outer wall of the top of the tooth 321. The inner wall of one side of the U-shaped fixing frame 3 is fixedly connected to a scraper 52.

[0034] The compression of the telescopic shell 2 pushes the flame retardant sleeve 21, so that the flame retardant sleeve 21 can be fixed at the connection between the plug 11 and the socket, and the plug 11 is wrapped, so as to avoid sparks when the plug 11 is connected to the socket, so that the sparks are directly exposed to the air, which is easy to cause the sparks to spread quickly. Accordingly, the connection between the plug 11 and the socket is covered by the flame retardant sleeve 21 to form a closed environment. In this oxygen-deficient space, the spread of sparks can be reduced. In addition, since the material of the flame retardant sleeve 21 is silicone rubber and it has the characteristics of high-temperature self-extinguishing, it will automatically extinguish within three seconds when it comes into contact with an open flame, effectively preventing the spread of the fire. By rotating the reduction wheel 31 and the gear seat 32, the resistance to the movement of the charging harness body 1 is increased when the charging harness body 1 moves forward, thereby slowing down the movement speed of the charging harness body 1 and allowing the plug 11 to be inserted into the inside of the socket, thereby avoiding the risk of electric sparks and short circuits caused by directly pushing the charging harness body 1 in too fast a speed. Accordingly, the speed at which the plug 11 is inserted into the socket can be controlled by the transmission of the reduction wheel 31, thereby reducing the risk of electric sparks or short circuits caused by rapid insertion, thereby reducing the possibility of electric shock.

[0035] Embodiment 2, on the basis of embodiment 1, the outer wall of the rotating shaft 33 is fixedly connected with hinge 2 42, the inner wall of hinge 2 42 is rotatably connected with the support plate 4, the inner part of one end of the support plate 4 is rotatably connected with hinge 1 41, the outer wall at the top of hinge 1 41 is fixedly connected with an arc plate 43, the outer wall of the rotating shaft 33 is provided with a groove 1 47, the lower part of the inner wall of the groove 1 47 is fixedly connected with a sensitive spring 46, the outer wall at the top of the sensitive spring 46 is fixedly connected with a mounting plate 45, the inner part of one side of the mounting plate 45 is rotatably connected with a T-shaped telescopic rod 44, and the outer wall of the T-shaped telescopic rod 44 is slidably connected with the inner part of the support plate 4.

[0036] After the arc plate 43 is opened, it can simultaneously rest against the bottom of the driving block 53 and the blocking block 6, and then through the sensitive spring 46 on the rotating shaft 33, even when the rotating shaft 33 is rotating slowly, the sensitive spring 46 will be extended outward by the centrifugal force, so that the mounting plate 45 pushes the support plate 4 to be opened, which correspondingly increases the force effect of the support plate 4, so that the support plate 4 can quickly enter the working state when the rotating shaft 33 is rotating.

[0037] Embodiment 3, on the basis of embodiment 2, the outer wall of one side of the reduction wheel 31 is fixedly connected to the L-shaped frame 5, the inner side of one side of the L-shaped frame 5 is slidably connected to the driving block 53, the upper part of the inner part of the driving block 53 is fixedly connected to the reset spring 2 55, the outer wall at the bottom of the reset spring 2 55 is fixedly connected to the lower part of the inner wall of one side of the L-shaped frame 5, the outer wall at the top of the driving block 53 is movably plugged into the inner wall of the groove 210, the inner side of the other side of the fixed sleeve 22 is movably plugged into the blocking shell 27, the outer wall at one end of the blocking shell 27 is movably plugged into the inner side of the flow hole 29, the inner wall of one side of the blocking shell 27 is fixedly connected to the reset spring 1 28, the outer wall at one end of the reset spring 1 28 is fixedly connected to the outer wall of the other side of the fixed sleeve 22, the inner wall of the blocking shell 27 is slidably connected to the moving rod 26, the outer wall of the moving rod 26 is fixedly connected to the friction pad 2, the inner wall of the blocking shell 27 is fixedly connected to the friction pad 1, and the outer wall at the bottom of the moving rod 26 is provided with a groove 210.

[0038] When the driving block 53 is driven to move by the L-shaped frame 5, the driving block 53 can push the groove 210 to move, and then through the movement of the groove 210, the moving rod 26 can drive the blocking shell 27 to move accordingly, so that one end of the blocking shell 27 leaves the inside of the flow hole 29, and the flow hole 29 can start to work. By utilizing the rotation of the reduction wheel 31 to drive the blocking shell 27 to move, the operator is prevented from having to free one hand to pull the blocking shell 27 to move when inserting the plug 11 into the socket. Correspondingly, the operator's operating steps are simplified, so that the operator only needs to complete the step of connecting the plug 11 to the socket to drive a series of functions to move.

[0039] Embodiment 4, on the basis of embodiment 1, a solution tank is provided inside the telescopic shell 2, the outer wall of one end of the solution tank is connected through the inside of the fixed sleeve 22, a flow hole 29 is provided above the outer wall of one side of the fixed sleeve 22, the outer wall of the flow hole 29 is fixedly connected to a connecting pipe 24, the outer wall of the bottom of the connecting pipe 24 is fixedly connected to a nozzle 25, the outer wall of one end of the nozzle 25 is fixedly connected to a fixing ring 23, a mounting seat 241 is fixedly connected to the lower part of the inner wall of one side of the fixing ring 23, and the inner wall of the mounting seat 241 is movably connected to a collecting tank 242.

[0040] The UV solution enters the interior of the connecting pipe 24 through the flow hole 29, and is finally sprayed to the highest point on the flame retardant sleeve 21 through the nozzle 25. The UV solution flows along the curvature of the flame retardant sleeve 21, thereby increasing the service life of the flame retardant sleeve 21, avoiding the flame retardant sleeve 21 from being exposed to the outdoor environment for a long time to increase the aging speed of the flame retardant sleeve 21, and correspondingly improving the wear resistance of the flame retardant sleeve 21, further isolating oxygen and heat transfer during combustion, and delaying the spread of fire.

[0041] Embodiment 5, on the basis of embodiment 4, a cavity is provided inside the reduction wheel 31, an entrance is provided inside the cavity at the connection of the L-shaped frame 5, a solution channel 541 is provided inside the L-shaped frame 5, a circular hole 54 is provided on the inner wall at one end of the solution channel 541, an inclined hole 51 is provided on the outer wall of the reduction wheel 31, the outer wall at the other end of the L-shaped frame 5 is movably connected to the interior of the reduction wheel 31, a square groove 63 is provided below the interior of the solution channel 541, a blocking block 6 is movably connected inside the square groove 63, a reset spring three 61 is fixedly connected to the outer wall on one side of the bottom of the blocking block 6, the outer wall on the top of the reset spring three 61 is fixedly connected to the outer wall of the bottom of the L-shaped frame 5, and a flow channel 62 is provided on the blocking block 6.

[0042] The inclined surface inside the inclined hole 51 facilitates the flow of the anti-corrosion liquid from the inclined hole 51 to the outer wall of the reduction wheel 31. The scraper 52 contacts the outer wall of the reduction wheel 31, so that when the anti-corrosion liquid flows to the outer wall of the reduction wheel 31, it can be scraped evenly by the scraper 52, thereby preventing the anti-corrosion liquid from moving along one trajectory all the time, thereby correspondingly increasing the covering effect of the anti-corrosion liquid.

[0043] The working principle and use process of the present invention are as follows: during operation, when the charging harness body 1 is used, first, the flame retardant sleeve 21 connected to one end of the charging harness body 1 is placed against the power source to align the plug 11 with the socket at the power source, and then the operator pushes the charging harness body 1 forward by hand. When the charging harness body 1 moves, the gear seat 32 can drive the reduction wheel 31 to rotate, and then the mechanical resistance is increased by rotating the reduction wheel 31 to further slow down the speed of inserting the plug 11 into the socket, so that the charging harness body 1 can push the plug 11 to slowly and smoothly insert into the socket, and then the flame retardant sleeve 21 and the telescopic shell 2 are set on the charging harness body 1, and the telescopic shell 2 is moved forward when the charging harness body 1 moves forward. The flame retardant sleeve 21 is compressed and pushed on the charging harness body 1 when the plug 11 is fully inserted into the socket. The flame retardant sleeve 21 is fixed at the connection between the plug 11 and the socket to wrap the plug 11, thereby avoiding sparks when the plug 11 is connected to the socket, exposing the sparks directly to the air, and easily causing the sparks to spread quickly. Accordingly, the connection between the plug 11 and the socket is covered inside by the flame retardant sleeve 21 to form a closed environment. In this oxygen-deficient space, the spread of sparks can be reduced. Since the material of the flame retardant sleeve 21 is silicone rubber and it has the characteristics of high-temperature self-extinguishing, it will automatically extinguish within three seconds when it comes into contact with an open flame, effectively preventing the spread of the fire.

[0044] By rotating the reduction wheel 31 and the gear seat 32, the resistance to the movement of the charging harness body 1 is increased when the charging harness body 1 moves forward, thereby slowing down the movement speed of the charging harness body 1 and allowing the plug 11 to be inserted into the inside of the socket, thereby avoiding the risk of electric sparks and short circuits caused by directly pushing the charging harness body 1 in too fast a speed. Accordingly, the speed at which the plug 11 is inserted into the socket can be controlled by the transmission of the reduction wheel 31, thereby reducing the risk of electric sparks or short circuits caused by rapid insertion, thereby reducing the possibility of electric shock.

[0045] It should be noted that: through the cooperation between the tooth 321 and the elastic block 323, the tooth 321 can move up and down inside the tooth seat 32. When the tooth 321 moves to the guide plate 322, the tooth 321 can enter the interior of the tooth seat 32 through the setting of the guide plate 322, and can enter the interior of the flame-retardant sleeve 21 with the tooth seat 32, thereby avoiding the tooth 321 from being intercepted when it moves to the fixed sleeve 22, and correspondingly facilitating the tooth seat 32 to enter the interior of the flame-retardant sleeve 21 with the charging harness body 1.

[0046] Through the fixed connection between the L-shaped frame 5 and the reduction wheel 31, the L-shaped frame 5 can be driven to move while the reduction wheel 31 rotates, and then through the contact between the driving block 53 and the inside of the second groove 210, when the L-shaped frame 5 drives the driving block 53 to move, the driving block 53 can push the second groove 210 to move, and then through the movement of the second groove 210, the moving rod 26 can drive the blocking shell 27 to move, so that one end of the blocking shell 27 leaves the inside of the flow hole 29, and the flow hole 29 can start to work. By utilizing the rotation of the reduction wheel 31 to drive the blocking shell 27 to move, the operator does not need to free up one hand to pull the blocking shell 27 to move when inserting the plug 11 into the socket. Correspondingly, the operator's operating steps are simplified, so that the operator only needs to complete the step of connecting the plug 11 to the socket to drive a series of functions to move.

[0047] It should be noted that: by cooperating with the friction pad 1 and the friction pad 2 respectively arranged on the moving rod 26 and the blocking shell 27, the blocking shell 27 can be driven to move along with the moving rod 26, and the friction force between the friction pad 1 and the friction pad 2 is greater than the elastic force of the reset spring 1 28 itself.

[0048] The outer wall of one end of the telescopic shell 2 is fixedly connected to the outer wall of the charging harness body 1, and the flame retardant sleeve 21 resists and cannot continue to move forward at the power source. At this time, when the charging harness body 1 moves forward, the telescopic shell 2 is compressed, so that the UV solution inside the telescopic shell 2 completely enters the interior of the fixed sleeve 22, which will increase the UV solution of the fixed sleeve 22. When the UV solution inside the fixed sleeve 22 rises to the flow hole 29, the UV solution passes through the flow hole 29 into the interior of the connecting pipe 24, and is finally sprayed to the highest point on the flame retardant sleeve 21 through the nozzle 25. The UV solution flows along the curvature of the flame retardant sleeve 21, thereby increasing the service life of the flame retardant sleeve 21, avoiding the flame retardant sleeve 21 being exposed to the outdoor environment for a long time to increase the aging speed of the flame retardant sleeve 21, and correspondingly improving the wear resistance of the flame retardant sleeve 21, further isolating oxygen and heat transfer during combustion, and delaying the spread of fire.

[0049] The excess UV solution can be collected through the collecting groove 242 provided at the bottom of the flame retardant sleeve 21, thereby preventing the UV solution from dripping on the ground and being inconvenient to clean.

[0050] It should be noted that: a piston rod is movably inserted into the outer wall of one side of the fixing sleeve 22 located on one side of the U-shaped fixing frame 3 , and the UV solution can be added into the fixing sleeve 22 by pulling out the piston rod.

[0051] When the reduction wheel 31 drives the rotating shaft 33 to rotate, the centrifugal force generated by the rotation of the reduction wheel 31 can be used to rotate the support plate 4 on the hinge 2 42, so that the support plate 4 drives the hinge 1 41 to move, and then the movement of the hinge 1 41 can be used to make the arc plate 43 move accordingly, so that the arc plate 43 is in an open state. After the arc plate 43 is opened, it can simultaneously rest against the bottom of the driving block 53 and the blocking block 6, and then through the sensitive spring 46 on the rotating shaft 33, even if the rotating shaft 33 is in a state of slow rotation, the sensitive spring 46 will be extended outward by the centrifugal force, so that the mounting plate 45 pushes the support plate 4 to be opened, which correspondingly increases the force effect of the support plate 4, so that the support plate 4 can quickly enter the working state when the rotating shaft 33 is rotating.

[0052] When the arc plate 43 contacts the bottom of the driving block 53, the driving force on the driving block 53 can be increased, so that when the driving block 53 drives the moving rod 26 to move, the arc surface of the driving block 53 contacts the second groove 210, which will generate a thrust on the driving block 53, so that the driving block 53 can enter the reset spring 255 into the L-shaped frame 5. Correspondingly, the setting of the arc plate 43 can increase the stability of the driving block 53, so that the driving block 53 can better drive the moving rod 26 to move. When the reduction wheel 31 stops moving, , so that the support plate 4 returns to its original position under the action of the centrifugal force. At this time, the moving rod 26 loses the driving force of the driving block 53 on it. At this time, under the action of the circulation hole 29, the blocking shell 27 can be pulled back, so that the blocking shell 27 is inserted into the interior of the circulation hole 29, and the circulation hole 29 can be blocked, avoiding the circulation hole 29 from continuing to move. Accordingly, the circulation hole 29 only works during the process of plugging the plug 11, preventing the circulation hole 29 from continuously releasing the UV solution inside the fixing sleeve 22.

[0053] Through the cooperation of friction pad 1 and friction pad 2, when the blocking shell 27 returns, the blocking shell 27 can drive the moving rod 26 to return. At this time, when the groove 210 contacts the arc surface of the driving block 53, the driving block 53 can be pushed downward along the arc surface, so that the driving block 53 enters the interior of the L-shaped frame 5, so that the moving rod 26 can return smoothly, avoiding the influence of the fixed connection between the driving block 53 and the L-shaped frame 5 on the return efficiency of the moving rod 26, and correspondingly increasing the flexibility of the driving block 53, so that the moving rod 26 can return smoothly.

[0054] It should be noted that when the baffle on the outer wall of the blocking shell 27 located inside the fixed sleeve 22 moves from the position of the flow hole 29 inside the fixed sleeve 22 to the other side, the movement of the blocking shell 27 can be restricted. At this time, when the reduction wheel 31 rotates, only the driving block 53 will drive the moving rod 26 to continue sliding inside the blocking shell 27. When the reduction wheel 31 rotates in the opposite direction, the moving rod 26 will be pushed into the interior of the blocking shell 27 again.

[0055] When the arc plate 43 is stretched open, the blocking block 6 can be pushed toward the interior of the solution channel 541. When the flow channel 62 enters the interior of the solution channel 541 through the square groove 63, it can contact the preservative at the connection between the solution channel 541 and the reduction wheel 31. At this time, the preservative inside the reduction wheel 31 will enter the interior of the solution channel 541 through the flow channel 62, and finally enter the interior of the inclined hole 51 through the circular hole 54. Since the interior of the inclined hole 51 is an inclined surface, it is convenient for the preservative liquid to flow from the inclined hole 51 to the outer wall of the reduction wheel 31. Then, through the contact between the scraper 52 and the outer wall of the reduction wheel 31, the preservative liquid can be scraped evenly when it flows to the outer wall of the reduction wheel 31, thereby avoiding the preservative liquid from moving along a trajectory all the time, thereby correspondingly increasing the covering effect of the preservative liquid.

[0056] Through the protective cover 12 and the wire mesh 13 arranged inside the charging harness body 1, the protective cover 12 directly blocks the contact between moisture, chemical corrosive media and the wires inside the charging harness body 1 through physical barriers, forming the first protective barrier. At the same time, it can also absorb external impact forces to prevent the wires from being damaged due to extrusion and friction. The wire mesh 13 evenly disperses the tension, pressure and other stresses on the charging harness body 1 through the weaving structure of metal wires, preventing the protective cover from being broken due to excessive local force.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
