[Technical Field]

[0001] (Related Applications) This application claims priority to a Chinese patent application bearing patent application number 202111028187.2, filed on September 2, 2021, and titled "Interlocking device for synchronously controlling multiple locking levers, charging device, and automobile."

[0002] The present invention relates to the technical field of new energy vehicles, and more particularly to a linkage device for synchronously controlling multiple lock levers, a charging device, and a vehicle. [Background technology]

[0003]

[0003] An electric vehicle, a new energy vehicle, is a vehicle that uses a single storage battery as its energy storage power source. The battery supplies electrical energy to the motor, driving the motor to operate the vehicle. Rechargeable batteries for electric vehicles mainly include lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, and lithium-ion batteries. These batteries can provide power to electric vehicles, and the electric vehicle uses the battery to store electrical energy and drive the motor to operate the vehicle normally. The batteries of electric vehicles are mainly charged by new energy vehicle charging guns.

[0004] In conventional charging technology, when a charging inlet is equipped with multiple charging ports, such as a DC charging port and an AC charging port, charging can be performed using different charging guns. The conventional technology uses multiple drive units to control the locking connection between the multiple charging ports and the charging guns, and each drive unit drives a corresponding lock lever to lock the charging gun into the corresponding charging stand for charging. This results in problems such as a large number of drive unit parts and high manufacturing costs.

[0005] Therefore, in the technical field of new energy vehicles, there is a need for an interlocking device, charging device, and vehicle that can synchronously control multiple locking levers by using one drive device to simultaneously control multiple locking levers to lock and connect them to the charging gun, thereby overcoming the deficiencies of the prior art and solving problems such as the large number of drive device parts and high manufacturing costs.

The terms used herein are only for describing specific embodiments and are not intended to limit the present application. As used herein, the term "and / or" includes any and all combinations of one or more associated elements.

[0019] As shown in FIGS. 1 to 6, the present invention provides an interlocking device 100 for synchronously controlling multiple lock levers. The interlocking device 100 includes a drive device 1, an interlocking structure 2 connected to an output end of the drive device 1, at least two lock levers connected to the interlocking structure 2, each lock lever connected to a charging gun head, and the drive device 1 synchronously moves each lock lever via the interlocking structure 2. The drive device includes, but is not limited to, a motor or an electronic lock. The interlocking structure 2 is connected to the output end of the motor or electronic lock and is capable of transmitting torque.

[0020] Furthermore, the movement is one or more of extension / contraction, translation, rotation, swing, bending, and twisting. The interlocking structure 2 moves at least two locking levers. The movement method may be determined according to the actual usage environment, as long as it can achieve simultaneous control of multiple locking levers.

[0021] Furthermore, the lock lever is inserted into a lock hole (conventional technology, not shown) of the charging gun to fix the charging gun.

[0022] One important purpose of the present invention is to lock the charging gun. To achieve this, each lock lever can be inserted into the lock hole of a different charging gun to lock it. This prevents the charging gun from falling off the charging inlet during charging, which would prevent the car from being unable to charge. Furthermore, a fallen charging gun that is charged poses a risk of electric shock.

[0023] In one specific embodiment, the shape of the locking lever is one or more of a cylinder, a truncated cone, a cone, an elliptical cylinder, an elliptical truncated cone, an elliptical cone, a polygonal prism, a polygonal truncated pyramid, and a polygonal pyramid, which may be determined according to the shape of the locking hole of the charging gun in actual use.

[0024] In one specific embodiment, a first locking lever 3 and a second locking lever 4 are connected to the interlocking structure 2, and the first locking lever 3 and the second locking lever 4 are arranged to form a first intersecting angle (the intersecting angle can be determined according to actual usage needs; in one specific embodiment of the present invention, the two are arranged perpendicular to each other). The first locking lever 3 is used to connect a first charging gun head (which can adopt a conventional charging structure in the prior art), and the second locking lever 4 is used to connect a second charging gun head (which can adopt a conventional charging structure in the prior art). The driver 1 synchronizes the first locking lever 3 and the second locking lever 4 via the interlocking structure 2. In this embodiment, the first locking lever 3 is an AC locking lever, the first charging gun head is an AC charging gun head, the second locking lever 4 is a DC locking lever, and the second charging gun head is a DC charging gun head. The motor synchronizes the first locking lever 3 and the second locking lever 4 via the interlocking structure 2.

[0025] In practical application, the interlocking device 100 for synchronously controlling a plurality of lock levers of the present invention is mounted in a hollow housing (not shown).

[0026] In one specific embodiment, the first locking lever 3 and the second locking lever 4 are actuating mechanisms, and as two actuating mechanisms, the first locking lever 3 and the second locking lever 4 are linked to the output end of the driving device 1 to synchronously extend and retract, acting as a stopper. By allowing one driving device 1 to synchronously control two or more actuating mechanisms via the linkage structure 2, it is possible to effectively reduce manufacturing costs and the number of sub-components.

[0027] The interlocking device for synchronously controlling multiple locking levers of the present invention is provided with an interlocking structure 2. One driving device 1 synchronously controls two operating mechanisms via the interlocking structure 2, which effectively reduces manufacturing costs, the number of sub-components, and the difficulty and cost of the assembly process.

[0028] 1 and 2, the interlocking structure 2 has a transmission shaft 20, which is coaxial with the output end of the drive device 1 and has a first end fixedly connected to the output end of the drive device 1. A first link rotation shaft 21 is provided at the first end of the transmission shaft 20 and is connected to the first lock lever 3, and the transmission shaft 20 can extend and retract the first lock lever 3 via the first link rotation shaft 21. A second link rotation shaft is provided at the second end of the transmission shaft 20 and is connected to the second lock lever 4, and the transmission shaft 20 can extend and retract the second lock lever 4 via the second link rotation shaft. The interlocking structure 2 allows the first lock lever 3 and the second lock lever 4 to extend and retract in synchronization.

[0029] Furthermore, the length of the first lock lever 3 is 5 mm to 55 mm, and the length of the second lock lever 4 is 5 mm to 55 mm.

[0030] If the first lock lever 3 and second lock lever 4 are too short, the locking operation cannot be completed, and if they are too long, they may interfere with the charging gun and cause abnormal noise. Therefore, the inventors conducted tests using first lock levers 3 and second lock levers 4 of different lengths. Here, the test was deemed to have failed if the locking operation could not be completed, and failed if abnormal noise was generated. The test results are shown in Table 1.

[0031] Table 1: Effect of different locking lever lengths on locking operation

[0032] [Table 1]

[0033] As can be seen from Table 1, if the length of the lock lever is less than 5 mm, the lock lever will not be able to lock the charging gun, and if the length of the lock lever is more than 55 mm, the lock lever may interfere with the charging gun and cause abnormal noise. Therefore, the inventors set the length of the first lock lever 3 to 5 mm to 55 mm, and the length of the second lock lever 4 to 5 mm to 55 mm.

[0034] Furthermore, the maximum stroke of the first lock lever is 5 mm to 36 mm, and the stroke of the second lock lever is 5 mm to 36 mm.

[0035] As mentioned above, if the maximum stroke of the first locking lever 3 and the second locking lever 4 is too short, the charging gun cannot be locked, and if it is too long, it may interfere with the charging gun and cause abnormal noise. Therefore, the inventors conducted tests using first locking lever 3 and second locking lever 4 with different maximum strokes. The test was deemed to have failed if the locking operation could not be completed, and failed if abnormal noise was generated. The test results are shown in Table 2.

[0036] Table 2: Effect of different lock lever maximum strokes on locking operation

[0037] [Table 2]

[0038] As can be seen from Table 2, if the maximum stroke of the lock lever is less than 5 mm, it will not be possible to lock it, and if the maximum stroke of the lock lever is greater than 36 mm, abnormal noise may occur. Therefore, the inventors set the maximum stroke of the first lock lever 3 to 5 mm to 36 mm, and the maximum stroke of the second lock lever 4 to 5 mm to 36 mm.

[0039] 2, the first link rotation shaft 21 is connected to a side wall of the first end of the transmission shaft 20, and the central axis of the first link rotation shaft 21 and the central axis of the transmission shaft 20 may be arranged parallel to each other or at another angle. The first link rotation shaft 21 is rotatable around its central axis together with the transmission shaft 20. The interlocking structure further includes a lever structure, and the first link rotation shaft 21 is rotatably and slidably connected to a first end of the lever structure, and a second end of the lever structure is rotatably and slidably connected to the first locking lever 3.

[0040] Furthermore, as shown in Figures 1 and 4, the lever structure has a lever 231, to which a lever rotation shaft 232 is connected, the lever rotation shaft 232 is fixedly installed, the central axis of the lever rotation shaft 232 and the central axis of the transmission shaft 20 are arranged parallel to each other, the lever 231 can rotate around the central axis of the lever rotation shaft 232 (the lever 231 can rotate around the lever rotation shaft 232 as its center), and the rotation direction of the lever 231 is opposite to the rotation direction of the transmission shaft 20.

[0041] Furthermore, as shown in Figures 1 and 4, the lever 231 is provided in an elongated shape, and a first sliding groove 233 is provided on the side wall of a first end of the lever. The first sliding groove 233 extends inward from the end face of the first end of the lever 231. The first link rotating shaft 21 is rotatably and slidably fitted into the first sliding groove 233. The width direction of the first sliding groove 233 and the central axis of the lever rotating shaft 232 are spatially arranged perpendicularly, and the width dimension of the first sliding groove 233 is equal to or greater than the outer diameter dimension of the first link rotating shaft 21.

[0042] Furthermore, the groove bottom of the first sliding groove 233 at one end close to the lever rotation shaft 232 is formed in an arc shape. The contour shape of the first sliding groove 233 may be adjusted according to actual needs.

[0043] Furthermore, the end face of the first end of the lever 231 is provided on a flat surface.

[0044] The contour shape of the lever 231, the mounting position of the lever rotation shaft 232, etc. may be adjusted according to the actual application, and the outer diameter dimension of the first link rotation shaft 21 and the width and length dimensions of the first sliding groove 233 may be determined according to the actual needs, resulting in a wide range of applications.

[0045] Furthermore, as shown in FIG. 2, a first connecting plate 201 extending radially outward is provided at a first end of the transmission shaft 20, and a first link rotation shaft 21 is provided on the first connecting plate 201.

[0046] Furthermore, as shown in Figure 3, a key groove 203 (square groove) is provided on the end face of the first end of the transmission shaft 20, and the output end of the drive device 1 is formed to match the key groove 203, and the transmission shaft 20 is connected to the output end of the drive device 1 via the key groove 203.

[0047] Furthermore, as shown in Figures 1 and 5, the first lock lever 3 has a first position control lever 31, and a first rotating shaft 32 is provided at one end of the first lock lever 3, the central axis of the first rotating shaft 32 and the central axis of the first position control lever 31 are arranged perpendicular to each other, and the first rotating shaft 32 is rotatably and slidably connected to the second end of the lever.

[0048] 5, a third sliding groove 234 is provided on the side wall of the second end of the lever 231, and the third sliding groove 234 extends inward from the end face of the second end of the lever 231. The first rotating shaft 32 is rotatably fitted in the third sliding groove 234, and the width direction of the third sliding groove 234 and the central axis of the lever rotating shaft 232 are spatially perpendicular to each other, and the width direction dimension of the third sliding groove 234 is larger than the outer diameter dimension of the first rotating shaft. The lever 231 is connected to the first link rotating shaft 21 of the transmission shaft 20, and the lever changes the direction of force between the lever 231 and the first rotating shaft 32 of the first lock lever 3, thereby ultimately converting the rotation of the first rotating shaft 32 into extension / contraction movement of the first position-limiting lever 31.

[0049] Furthermore, the groove bottom of the third sliding groove 234 at one end close to the lever rotation shaft 232 is formed in an arc shape.

[0050] 5, an L-shaped third connecting plate 33 is connected to one end of the first position restricting lever 31, and a first rotating shaft 32 is provided on the third connecting plate 33. The contour shape of the third connecting plate 33 may be adjusted according to actual applications.

[0051] Furthermore, as shown in Figures 1 and 2, the second link rotating shaft has a second rotating shaft 22, which is connected to the side wall of the second end of the transmission shaft 20, and the central axis of the second rotating shaft 22 and the central axis of the transmission shaft 20 are arranged parallel to each other, and the second rotating shaft 22 can rotate around its central axis together with the transmission shaft 20, and the second rotating shaft 22 is rotatably and slidably connected to the first end of the second lock lever 4.

[0052] 6, the second lock lever 4 has a second position restriction lever 41, and a second sliding groove 42 is provided at one end of the second lock lever 4, the central axis of the second rotating shaft 22 and the central axis of the second position restriction lever 41 are arranged perpendicular to each other, the second rotating shaft 22 is rotatably and slidably engaged in the second sliding groove 42, the width direction of the second sliding groove 42 and the central axis of the second position restriction lever 41 are arranged parallel to each other, and the width direction dimension of the second sliding groove 42 is equal to or greater than the outer diameter dimension of the second rotating shaft 22. By connecting the second lock lever 4 and the second rotating shaft 22, the rotation of the second rotating shaft 22 is converted into the extension / contraction movement of the second position restriction lever 41.

[0053] Furthermore, the first rotary shaft 32 and the second rotary shaft 22 have the same rotation radius. By making them have the same rotation radius, the first lock lever 3 and the second lock lever 4 can be locked synchronously.

[0054] Furthermore, the second sliding groove 42 is provided in the shape of a rectangle, a parallelogram, a polygon, a trapezoid, a rhombus, or an elongated circle.

[0055] Furthermore, as shown in Figure 6, a second lock lever connection click plate 43 is provided at one end of the second position control lever 41, a second sliding groove 42 is provided on one side of the second lock lever connection click plate 43, and a transition slope is provided between the second lock lever connection click plate 43 and the second position control lever 41.

[0056] Furthermore, as shown in FIG. 2, a second connecting plate 202 extending radially outward is provided at the second end of the transmission shaft 20, and a second rotating shaft 22 is provided on the second connecting plate 202.

[0057] The diameters of the lock levers of the first position control lever 31 and the second position control lever 41 are determined according to actual needs, and the settings of each hinge location and each moment arm in the interlocking structure 2 are determined according to actual needs.

[0058] The operation process of the interlocking device for synchronously controlling a plurality of lock levers of the present invention is as follows: Torque is input by a driving device 1 (motor), the transmission shaft 20 is connected to the output end of the driving device 1 via a key groove 203, and the output end of the driving device 1 rotates the transmission shaft 20 via the key groove 203; The first link rotating shaft 21 and the second rotating shaft 22 rotate together with the transmission shaft 20 around its central axis; The first link rotation shaft 21 rotates while being fitted into the first slide groove 233, and the first link rotation shaft 21 rotates the lever 231 around the central axis of the lever rotation shaft 232, where the rotation direction of the lever 231 and the rotation direction of the first link rotation shaft 21 are opposite to each other; The first rotation shaft 32 of the first lock lever 3 rotates while being fitted into the third slide groove 234, and the rotation of the lever 231 causes the first position restriction lever 31 to extend or contract (move along the central axis of the first position restriction lever 31), thereby extending or contracting the first lock lever 3; The second rotating shaft 22 is rotatably and slidably fitted into the second sliding groove 42, and the rotation of the second rotating shaft 22 causes the second position control lever 41 to move in an extending or retracting direction (moving along the central axis direction of the second position control lever 41), thereby extending or retracting the second lock lever 4.

[0059] In some embodiments, the output power of the driver 1 is between 0.35W and 5.56W.

[0060] The operating speed of the interlocking device depends on the output power of the drive unit 1. The higher the power, the faster the interlocking device completes its operation. The lower the power, the slower the interlocking device completes its operation. This may result in insufficient rotational torque on the transmission shaft 20, preventing the first locking lever 3 and the second locking lever 4 from completing their locking operations. To verify the effect of output power on interlocking device operation, the inventors conducted related tests. The test method involved selecting drive units 1 with different output powers, and using the same interlocking device structure. Each drive unit 1 was operated continuously for one minute, and the number of complete interlocking operations was recorded. A complete count of 40 or more was considered a pass, and a count of less than 40 was considered a fail. Abnormal noise during interlocking device operation was also considered a fail. The results are shown in Table 3.

[0061] Table 3: Effect of different output power on interlocking speed and noise

[0062] [Table 3]

[0063] As shown in Table 3, after the output power of the drive unit 1 falls below 0.35W, the number of locking operations completed by the interlocking device within one minute is less than 40, which is too slow and unacceptable, so the inventors set the minimum power of the drive unit 1 to 0.35W. After the output power of the drive unit 1 exceeds 5.56W, the interlocking device enters a speed bottleneck period due to the overall design, and no significant improvement is achieved and abnormal noise occurs. Therefore, the inventors set the output power of the drive unit 1 to 0.35W to 5.56W. Specifically, it may be 0.9W, 0.96W, 1W, 1.08W, etc.

[0064] In some embodiments, the driving device 1 has an output end, and the output torque of the output end is 2.25 N·mm to 9.85 N·mm.

[0065] The magnitude of the force applied to the transmission shaft 20 depends on the output torque of the drive unit 1; if the torque is insufficient, the first lock lever 3 and the second lock lever 4 cannot be operated. To verify the effect of different output torques on the operation of the interlocking device of the drive unit 1, the inventors conducted related tests. As a test method, drive units 1 with different output torques were selected, with the other structures of the interlocking device remaining the same. If the drive unit 1 can operate the transmission shaft 20 normally, it is considered to be passed; if not, it is considered to be failed. If abnormal noise occurs during operation of the interlocking device, it is also considered to be failed. The test results are shown in Table 4.

[0066] Table 4: Whether the drive device 1 with different output torques can operate the transmission shaft 20 normally

[0067] [Table 4]

[0068] As shown in Table 4, if the output torque of the drive unit 1 is less than 2.25 N·mm, the transmission shaft 20 cannot be operated, so the inventors set the output torque of the drive unit 1 to a minimum of 2.25 N·mm. If the output torque exceeds 9.85 N·mm, the transmission shaft 20 can be operated, but because an output torque that is too large causes abnormal noise when the interlocking device is operating, the inventors set the output torque of the drive unit 1 to 2.25 N·mm to 9.85 N·mm. Specifically, it may be 3.5 N·mm, 4 N·mm, etc.

[0069] In some embodiments, the rotation angle of the transmission shaft 20 is between 15° and 92°.

[0070] The stroke of the first and second locking levers 3 and 4 also depends on the rotation angle of the transmission shaft 20. If the rotation angle of the transmission shaft 20 is too small, the stroke of the first and second locking levers 3 and 4 is insufficient, preventing the locking operation. If the rotation angle of the transmission shaft 20 is too large, the transmission shaft 20 continues to output rotational force after the first and second locking levers 3 and 4 are extended to their operating positions, potentially damaging the interlocking device. To verify the effect of the rotation angle of the transmission shaft 20 on the interlocking device, the inventors conducted tests. For the test, drives 1 with different rotation angles of the transmission shaft 20 were prepared, with the other structures of the interlocking device remaining the same. If the stroke of the first and second locking levers 3 and 4 was sufficient to complete the locking operation, the interlocking device was deemed pass; otherwise, it was deemed fail. A larger rotation angle means a larger stroke of the first and second locking levers 3 and 4, which requires a corresponding increase in the size of each connecting component, which can easily come into contact with other components in the interlocking device and affect its use. In this case, the rotation angle of the transmission shaft 20 is also deemed to be unacceptable. The test results are shown in Table 5.

[0071] Table 5: Effects of different rotation angle ranges of the transmission shaft on the interlocking device function and whether or not there is contact with other parts

[0072] [Table 5]

[0073] As can be seen from Table 5, when the rotation angle of the transmission shaft 20 was less than 15°, the stroke of the first lock lever 3 and the second lock lever 4 was insufficient, and the locking operation could not be completed. When the rotation angle of the transmission shaft 20 was greater than 92°, unnecessary contact occurred between the components of the interlocking device, generating abnormal noise, and the test was rejected. Therefore, the inventors set the rotation angle of the output end of the transmission shaft 20 to 15° to 92°. Specifically, it may be 50°, 60°, 70°, or 80°, etc.

[0074] Furthermore, the material of the transmission shaft 20 includes metals and non-metals.

[0075] In addition, the materials for the transmission shaft 20 include carbon steel, all copper, pure copper, aluminum-coated zinc, aluminum-coated copper or zinc alloy, which have better strength and toughness and can better meet the requirements of the transmission shaft.

[0076] Furthermore, the material of the transmission shaft 20 includes one or more of polyvinyl chloride, polyethylene, polyamide, polytetrafluoroethylene, tetrafluoroethylene / hexafluoropropylene copolymer, ethene / tetrafluoroethylene copolymer, polypropylene, polyvinylidene fluoride, polyurethane, polyterephthalic acid, polyurethane elastomer, styrene block copolymer, perfluoroalkoxyalkane, chlorinated polyethylene, polyphenylene sulfide, polystyrene, cross-linked polyolefin, ethene / vinyl acetate copolymer, cross-linked polyethylene, polycarbonate, polysulfone, polyphenylene oxide, polyester, phenolic resin, urea formaldehyde, styrene-acrylonitrile copolymer, polymethacrylate, and polyoxymethylene resin.

[0077] Taking polyoxymethylene, polyester, polycarbonate, polyamide, polyphenylene sulfide, and polytetrafluoroethylene as examples, polyoxymethylene is a smooth, glossy, hard, and dense material with a light yellow or white color that can be used for long periods of time within a temperature range of -40°C to 100°C. Its wear resistance and self-lubricating properties are superior to most engineering plastics, and it has good oil and peroxide resistance.

[0078] Polyester is generally obtained by polymerizing terephthalic acid and butylene glycol, and has a hard segment portion and a soft segment portion, and is a thermoplastic elastomer.

[0079] Polycarbonate has high strength, a high modulus of elasticity, and high impact strength, excellent fatigue resistance, good dimensional stability, little creep, high transparency, and free dyeability.

[0080] Polyamides are non-toxic, lightweight, have excellent mechanical strength, and have good wear resistance and corrosion resistance, and are used to manufacture bearings, gears, pump blades and other parts in industries such as machinery, chemicals, instruments and automobiles, replacing metals such as copper.

[0081] Polyphenylene sulfide is a new type of high-performance thermoplastic resin that has advantages such as high mechanical strength, high temperature resistance, chemical resistance, flame retardancy, excellent thermal stability, and excellent electrical performance.

[0082] Polytetrafluoroethylene is resistant to acids, bases, and various organic solvents, is practically insoluble in all solvents, and is resistant to high temperatures.

[0083] Furthermore, the material of the transmission shaft 20 includes glass fiber, which makes the transmission shaft 20 stronger and has a certain degree of smoothness.

[0084] Furthermore, the material of the first lock lever 3 and the second lock lever 4 includes one or more of polyvinyl chloride, polyethylene, polyamide, polytetrafluoroethylene, tetrafluoroethylene / hexafluoropropylene copolymer, ethene / tetrafluoroethylene copolymer, polypropylene, polyvinylidene fluoride, polyurethane, polyterephthalic acid, polyurethane elastomer, styrene block copolymer, perfluoroalkoxyalkane, chlorinated polyethylene, polyphenylene sulfide, polystyrene, cross-linked polyolefin, ethene / vinyl acetate copolymer, cross-linked polyethylene, polycarbonate, polysulfone, polyphenylene oxide, polyester, phenolic resin, urea formaldehyde, styrene-acrylonitrile copolymer, polymethacrylate, and polyoxymethylene resin.

[0085] Taking polyoxymethylene, polycarbonate, and polyamide as examples, polyoxymethylene is a smooth, glossy, hard, and dense material with a light yellow or white color that can be used for long periods of time within a temperature range of -40°C to 100°C. Its wear resistance and self-lubricating properties are superior to most engineering plastics, and it has good oil and peroxide resistance.

[0086] Polycarbonate is colorless and transparent, heat-resistant, impact-resistant, and flame-retardant to BI standard. It also has good mechanical properties at normal operating temperatures. Compared to its close cousin, polymethyl methacrylate, polycarbonate has better impact resistance, a higher refractive index, and easier processing, as well as a high level of flame retardancy without the need for additives.

[0087] Polyamide is non-toxic, lightweight, and has excellent mechanical strength, as well as good wear resistance and corrosion resistance, and is used in place of metals such as copper to manufacture bearings, gears, pump blades, and other parts in industries such as machinery, chemicals, instruments, and automobiles. Since the first locking lever 3 and the second locking lever 4 are required to have properties such as high strength, high heat resistance, and high wear resistance, polycarbonate or polyamide is preferred for the first locking lever 3 and the second locking lever 4.

[0088] In a specific embodiment, the first rotating shaft 32 and the second rotating shaft 22 are coated with a wear-resistant plating layer.

[0089] Furthermore, the material of the wear-resistant layer includes ceramic, alloy, oxide or fluoroplastic.

[0090] In a preferred embodiment, the wear-resistant plating layer includes one or more of gold, silver, nickel, tin, tin-lead alloy, zinc, silver-antimony alloy, palladium, palladium-nickel alloy, graphite silver, hard silver, graphene silver, and silver-gold-zirconium alloy.

[0091] For the corrosion resistance time test shown in Table 6 below, the first rotating shaft 32 and the second rotating shaft 22 were placed in a salt spray test box. Each location on the first rotating shaft 32 and the second rotating shaft 22 was sprayed with salt water. Every 20 hours, the shafts were removed, cleaned, and the surface corrosion was observed. This constituted one cycle. If the area of ​​surface corrosion on the first rotating shaft 32 and the second rotating shaft 22 exceeded 10% of their total area, the test was stopped and the number of cycles recorded. In this example, a test result of fewer than 80 cycles was deemed a failure. Regarding the number of insertions and removals shown in Table 6, the first rotating shaft 32 and the second rotating shaft 22 were fixed to a test bench. Damage to the wear-resistant plating on the first rotating shaft 32 and the second rotating shaft 22 was observed every 100 insertions and removals. If damage occurred, exposing the material of the first rotating shaft or the second rotating shaft itself, the test was stopped and the number of insertions and removals recorded. In this example, a test result of fewer than 8,000 insertions and removals was deemed a failure.

[0092] Table 6: Effect of different plating layer materials on the number of insertions and withdrawals of the first and second rotating shafts and corrosion resistance

[0093] [Table 6]

[0094] As can be seen from Table 6 above, when the plating layer material is gold, silver, silver-antimony alloy, palladium, palladium-nickel alloy, graphite silver, hard silver, graphene silver, and silver-gold-zirconium alloy, the experimental results far exceed the standard values ​​and the performance is relatively stable.When the plating layer material is nickel, tin, tin-lead alloy, or zinc, the experimental results also meet the requirements.Therefore, the inventor selects one or more of gold, silver, nickel, tin, tin-lead alloy, zinc, hard silver, silver-antimony alloy, palladium, palladium-nickel alloy, graphite silver, graphene silver, and silver-gold-zirconium alloy as the plating layer material.

[0095] The present invention further provides a charging device including a linkage device that synchronously controls the above-mentioned plurality of lock levers.

[0096] The present invention further provides a vehicle equipped with a linkage device for synchronously controlling the above-described plurality of lock levers.

[0097] As described above, the interlocking device for synchronously controlling a plurality of lock levers, the charging device, and the automobile of the present invention can achieve the following beneficial effects.

[0098] (1) In the interlocking device for synchronously controlling multiple locking levers of the present invention, an interlocking structure is arranged so that one driving device can synchronously control two or more operating mechanisms through the interlocking structure, thereby effectively reducing manufacturing costs, the number of sub-components, and the difficulty and cost of the assembly process.

[0099] (2) The interlocking structure of the present invention utilizes the principles of position restriction and sliding grooves, and by changing the direction of force using a lever, it is possible to synchronize the movement of multiple lock levers.

[0100] (3) In the interlocking structure of the present invention, the structure of each component is simple, making it easy to manufacture and advantageous for widespread use.

[0101] The above are only exemplary embodiments of the present invention, and do not limit the scope of the present invention. It is obvious to those skilled in the art that any equivalent variations and modifications made without departing from the spirit and principle of the present invention fall within the protection scope of the present invention.
