[0004] With the increasing popularity of electric vehicles, the market demand for charging plugs and charging stations is also increasing. In the prior art, charging stations in charging systems typically include charging terminals and cables. The charging terminals and cables are connected internally to the charging station, with the charging terminals fixed to the charging station body, and the cables connected to the charging terminals. Due to excessive plugging and unplugging, or due to electrical shorts, some charging terminals within the charging station can become damaged. To repair or replace charging terminals, all cables must be removed from the vehicle body, followed by the rear cover of the charging station and the charging terminals connected to the cables. Since the charging terminals and cables are typically welded together, damaged electrical connections must be cut off. Furthermore, since the cable length is set to a length that leaves no room for repair, the cable may need to be replaced. This requires removing the entire cable casing and tape before repairing the charging station. This entire process is labor-intensive and time-consuming, significantly impacting after-sales service efficiency. Therefore, a new solution to address these issues is urgently needed.

[0061] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0062] The present application provides a charging stand, as shown in Figures 1-2, including: The present application provides a charging stand, including: a charging stand body 1, a charging terminal 2, an adapter 3 and a cable 4, wherein the adapter 3 includes a detachable structure 31 and a fixed end 32 connected in sequence, the fixed end 32 is electrically connected to the conductor of the cable 4, and the adapter 3 is fixedly installed on the charging stand body 1. As shown in Figure 3, a connecting structure 9 is provided on the charging terminal 2, and the charging terminal 2 is detachably connected to the detachable structure 31 through the connecting structure 9.

[0063] In existing charging stations, the charging terminal 2 is a component that is frequently plugged and unplugged from the charging station body 1 and is the primary component for conducting the charging current. Over extended use, this frequent plugging and unplugging can cause deformation or damage to the plating of the charging terminal 2. In some cases, excessive current can cause the charging terminal 2 to spark and melt, rendering it incapable of conducting electricity. Furthermore, since the charging terminal is exposed to the external environment, it can be corroded by water or salt, which can also cause the electrical performance of the charging terminal 2 to fall short of expectations. Therefore, the charging terminal 2 is the most vulnerable component of the charging station. However, in most current charging stations, the charging terminal 2 is fixed to the charging station body and welded to the cable 4. Damage to the charging terminal 2 requires the complete removal and replacement of the charging terminal 2 and the cable 4 from the charging station body 1. In severe cases, the entire charging station body 1 may even need to be replaced. This cumbersome maintenance operation, long labor hours, and high maintenance costs are currently one of the major issues hindering the development of the rechargeable vehicle industry.

[0064] The present application provides a charging stand. When the charging terminal 2 is damaged, it is only necessary to remove the charging terminal 2 from the charging stand body 1, replace the charging terminal 2, and then install it. There is no need to remove the entire charging stand body 1 or replace the cable 4. This solves the technical problem of cumbersome maintenance work when the charging terminal 2 of the charging stand body 1 is damaged.

[0065] A cavity is provided at the front end of the charging seat 1 , the detachable structure 31 is provided inside the cavity, and the charging terminal 2 is inserted from the opening of the cavity and detachably connected to the detachable structure 31 through the connecting structure 9 .

[0066] In some embodiments, the adapter 3 and the conductor are connected or integrally formed by crimping or welding. Preferably, as shown in FIG6 , the fixed end 32 of the adapter 3 is a solid body, and the conductor of the cable 4 can be wrapped around the outside of the fixed end of the solid body and welded together. As shown in FIG7 , the fixed end 32 of the adapter 3 is a hollow body, and the conductor of the cable 4 can be inserted into the hollow body of the fixed end and crimped together.

[0067] In some embodiments, the welding method includes one or more of resistance welding, friction welding, ultrasonic welding, arc welding, laser welding, electron beam welding, and pressure diffusion welding.

[0068] Ultrasonic welding uses high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, the two surfaces of the objects rub against each other to form a fusion between the molecular layers.

[0069] Resistance welding refers to a method of welding that uses a strong current to pass through the contact point between the electrode and the workpiece, generating heat due to the contact resistance.

[0070] Arc welding refers to the use of electric arc as a heat source and the physical phenomenon of air discharge to convert electrical energy into the thermal energy and mechanical energy required for welding, thereby achieving the purpose of connecting metals. The main methods include arc welding, submerged arc welding, gas shielded welding, etc.

[0071] Pressure welding is a method of applying pressure to the weldment to bring the joint surfaces into close contact and produce a certain amount of plastic deformation to complete the welding.

[0072] Electron beam welding refers to the use of accelerated and focused electron beams to bombard the welding surface placed in a vacuum or non-vacuum, melting the workpiece to achieve welding.

[0073] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source.

[0074] Friction welding refers to a method of welding that uses the heat generated by friction between the contact surfaces of the workpieces as a heat source to cause the workpieces to undergo plastic deformation under pressure.

[0075] In some embodiments, the number of adapters 3 ranges from 2 to 36. This can be simplified to requiring only two cables 4 for charging, with the remaining circuits integrated into the charging device or battery. Furthermore, the number of charging terminals 2 can be the same as the number of adapters 3, also ranging from 2 to 36.

[0076] In some embodiments, the charging base 1 is provided with a card slot 5, and the adapter 3 is provided with a groove 6. The card slot 5 cooperates with the groove 6 to prevent the adapter 3 from moving along the axial direction.

[0077] In some embodiments, the charging seat body 1 is provided with a wire outlet 11, and the cable 4 is passed through the wire outlet 11 to facilitate the insertion and assembly of the cable 4, and the installation position of the cable 4 can be sealed to ensure the waterproofness of the charging seat body 1, making operation more convenient and improving assembly efficiency.

[0078] The wire outlet 11 can limit the wire outlet position and wire outlet direction of the cable 4. In one embodiment, the wire outlet 11 is arranged toward the side of the charging seat body 1. The wire outlet 11 is arranged in the up and down direction, the cable 4 is outlet in the up and down direction, and the cable 4 can be bent. In one embodiment, the wire outlet 11 is arranged in the horizontal direction, the cable 4 is outlet in the horizontal direction, and the cable 4 can be bent. Furthermore, the charging seat body 1 is provided with at least two groups of wire outlets, one group of which is arranged in the up and down direction, and the other group is arranged in the horizontal direction. When in use, one of the groups can be selected to arrange the cable 4, so that the outlet direction of the cable 4 is adapted to the installation environment.

[0079] In one embodiment, the direction of the cable outlet 11 is at a certain angle to the front-to-back direction of the charging base 1. In the installation environment of the charging base 1, the cable 4 of the charging base 1 may not necessarily be located at the rear or side of the charging base 1, but may also be at a certain angle to the axial direction of the charging base 1. The direction of the cable outlet 11 can be directly set to the required cable outlet direction of the installation environment, avoiding the need to bend the cable 4 again. During installation, the cable 4 can also be directly installed, avoiding the situation where the cable 4 cannot be bent due to its high rigidity.

[0080] A sealing ring 7 is provided between the adapter 3 and the charging base 1. As shown in Figures 6 and 7, the sealing ring 7 can play a sealing role to prevent water or dust from entering between the adapter 3 and the charging base 1.

[0081] Furthermore, the charging terminal 2 is provided with a disassembly portion 8 at the rear end, as shown in Figures 4 and 5 . The cross-section of the disassembly portion 8 is flat or polygonal. The disassembly portion 8 facilitates installation of the charging terminal 2. A worker can rotate the charging terminal 2 by contacting the disassembly portion 8 to install the charging terminal 2.

[0082] In some embodiments, the detachable structure is a bolt structure, the connecting structure is a threaded structure, and the torque range of the screw connection between the detachable structure 31 and the connecting structure 9 is 0.1N·m-30N·m.

[0083] To verify the effect of the torque range for threading the detachable structure 31 to the connecting structure 9 on the electrical connection performance between the charging terminal 2 and the adapter 3, the inventors selected identical charging terminals 2 and adapters 3 and tightened them together using different torques. The authors then tested the contact resistance between the charging terminal 2 and adapter 3 and the connection between the charging terminal 2 and adapter 3 after a vibration test. The test results are shown in Table 1.

[0084] The contact resistance between the charging terminal 2 and the adapter 3 is tested using a microresistance meter. One end of the meter is placed on the adapter 3, and the other end is placed on the charging terminal 2. The placement of the meter remains the same for each measurement. The contact resistance reading is then read from the meter. In this embodiment, a contact resistance greater than 1 mΩ is considered unacceptable.

[0085] The vibration test involves placing the connected sample on a vibration test bench and subjecting it to 300 vibration cycles, each cycle requiring vibration in six directions at a frequency of 100 Hz and a single-direction acceleration of 40 m / s². The test then examines whether the charging terminal 2 and the adapter 3 are loose. In this embodiment, looseness between the detachable structure 31 and the connecting structure 9 or damage during installation constitutes a failure.

[0086] Table 1 Effect of different torques on contact resistance and connection conditions

[0087]

[0088] As can be seen from Table 1 above, when the torque value of the threaded connection between the detachable structure 31 and the connecting structure 9 is less than 0.1 N·m, the contact resistance value between the charging terminal 2 and the adapter 3 is unqualified. In addition, the detachable structure 31 and the connecting structure 9 become loose after the vibration test. Therefore, the inventors set the minimum value of the torque range for the threaded connection between the detachable structure 31 and the connecting structure 9 to 0.1 N·m. When the torque value of the threaded connection between the detachable structure 31 and the connecting structure 9 is greater than 30 N·m, the contact resistance can no longer be further reduced. Therefore, the inventors set the torque range for the threaded connection between the detachable structure 31 and the connecting structure 9 to be 0.1 N·m-30 N·m.

[0089] In some embodiments, the detachable structure 31 is a claw and the connecting structure 9 is a slot, or the detachable structure 31 is a slot and the connecting structure 9 is a claw, and the connection force range of the detachable structure 31 and the connecting structure 9 is 5N-500N.

[0090] In order to test the effect of the connection force between the detachable structure 31 and the connecting structure 9 on the conductivity, the inventors selected 10 pairs of detachable structures 31 and the connecting structure 9 with the same shape and the same expansion and contraction gap width to conduct connection force tests. The test results are shown in Table 2.

[0091] Table 2 Effect of different connection forces on conductivity.

[0092]

[0093] As shown in Table 2, when the connection force is less than 5N or greater than 500N, the conductivity decreases significantly, failing to meet practical requirements. When the connection force is greater than 5N and less than 500N, the conductivity is good, and when the connection force is greater than 15N and less than 300N, the conductivity is also excellent. However, when the connection force exceeds 300N, the conductivity does not increase significantly and processing becomes difficult. Therefore, the inventors believe that the optimal connection force is 15N-300N.

[0094] In some embodiments, the charging base 1 further includes a fixing portion, which prevents the adapter 3 from rotating around an axis.

[0095] A threaded hole is provided on the charging seat body, a connecting hole is provided on the fixing portion, and the fixing portion further comprises a screw, which passes through the connecting hole and is screwed into the threaded hole to fix the fixing portion on the charging seat body.

[0096] In some embodiments, the cable 4 is made of copper or copper alloy or aluminum or aluminum alloy. Due to the high voltage and large current of electric vehicle cables, large diameter wires are required to conduct current. Copper conductor materials have good electrical conductivity and ductility, and are preferred as cable conductor materials. However, with the rising price of copper, the material cost of using copper as a conductor will become increasingly higher. For this reason, people have begun to look for substitutes for metallic copper to reduce costs. The content of metallic aluminum in the earth's crust is about 7.73%. After the refining technology is optimized, the price is relatively low. In addition, compared with copper, aluminum is lighter and its electrical conductivity is second only to copper. Aluminum can replace part of copper in the field of electrical connections. Therefore, replacing copper with aluminum is a development trend in the field of automotive electrical connections.

[0097] The charging base 1 is provided with a temperature sensor and a control board, and the temperature sensor is electrically connected to the control board via a data line.

[0098] Furthermore, the temperature sensor is in contact with the adapter 3 .

[0099] Furthermore, the temperature sensor is integrally formed with the adapter 3. The integrally formed design is more convenient to install and the measured temperature value is more accurate.

[0100] The temperature sensor transmits the temperature signal to the control board, monitoring the temperature of the adapter 3 and preventing damage caused by excessive temperature. Furthermore, the temperature sensor can be directly connected to the adapter 3 to obtain the temperature value of the adapter 3 in real time and transmit it to the control board. The control board adjusts the charging current to control the temperature value of the adapter 3, making the measurement accuracy of the adapter 3 close to or equal to the theoretical absolute value, with extremely high detection accuracy and fast output capability.

[0101] Furthermore, the control board is a circuit board with a built-in control logic circuit. Through this control logic circuit, when the detected temperature of the temperature sensor is higher than the set temperature, the control board issues a warning message to achieve real-time temperature monitoring; when the detected temperature of the temperature sensor exceeds a certain value of the set temperature, the charging system is controlled to automatically disconnect to avoid danger caused by excessive temperature.

[0102] Specifically, the temperature sensor can be an NTC temperature sensor or a PTC temperature sensor. The advantages of using these two temperature sensors are their small size and ability to measure gaps that other thermometers cannot. They are also easy to use, with resistance values ​​​​selectable between 0.1Ω and 100kΩ. They can be easily processed into complex shapes and can be mass-produced. They have good stability and strong overload capacity, making them suitable for products such as adapters that require small size and stable performance.

[0103] The cross-sectional area of ​​the connection structure 9 of the charging terminal 2 is smaller than or equal to the cross-sectional area of ​​the detachable structure 31. This ensures that the resistance of the resistor at the connection point is not too large.

[0104] In some preferred embodiments, the charging terminal 2 has a first plating layer.

[0105] The material of the first plating layer includes one or more of gold, silver, nickel, tin, tin-lead alloy, zinc, silver-antimony alloy, palladium, palladium-nickel alloy, graphite silver, graphene silver and silver-gold-zirconium alloy.

[0106] The charging terminals 2 undergo oxidation reactions with oxygen and water during use, necessitating a coating of one or more inactive metals to extend the terminal's lifespan. Furthermore, metal contacts, which are frequently plugged and unplugged, require a coating of a highly wear-resistant metal to significantly extend their lifespan. Furthermore, the contacts require excellent electrical conductivity. The aforementioned metals, with their superior conductivity and stability compared to copper or copper alloys, offer improved electrical performance and a longer service life.

[0107] Furthermore, a second coating is provided on the surface of the detachable structure.

[0108] Preferably, the material of the second plating layer contains one or more of gold, silver, nickel, tin, tin-lead alloy, zinc, silver-antimony alloy, palladium, palladium-nickel alloy, graphite silver, graphene silver and silver-gold-zirconium alloy.

[0109] To demonstrate the impact of different plating materials on the overall performance of the charging terminal 2, the inventors used charging terminal 2 samples with the same specifications and materials, but with different plating materials, and conducted a series of plug-in and pull-out tests and corrosion resistance tests using matching connectors of the same specifications. To demonstrate the advantages and disadvantages of the selected materials and other commonly used electroplating materials, the inventors also used tin, nickel, and zinc as plating materials in the experiments. The experimental results are shown in Table 3 below.

[0110] The plugging and unplugging times reported in Table 3 below were calculated by fixing the charging terminals 2 on a test bench and using a mechanical device to simulate plugging and unplugging the terminals. After every 100 plugging and unplugging cycles, the test was stopped to observe damage to the surface plating of the charging terminals 2. If scratches appeared on the surface plating, exposing the terminal material, the test was stopped and the plugging and unplugging times recorded. In this example, plugging and unplugging times less than 8,000 cycles were considered unacceptable.

[0111] The corrosion resistance time test in Table 3 below involved placing charging terminal 2 in a salt spray test chamber. Salt spray was applied to various locations on the terminal. The terminal was removed for cleaning and observed for surface corrosion every 20 hours. This constituted a cycle. Testing was stopped when the surface corrosion area exceeded 10% of the total terminal area. The cycle count was then recorded. In this embodiment, a cycle count of less than 80 was considered unsatisfactory.

[0112] As can be seen in Table 3 below, when the plating material for charging terminal 2 is the commonly used metals tin, nickel, and zinc, the experimental results are far inferior to those of other selected metals. Although the nickel plating passes the plug-in and unplug test, it does not exceed the standard by much, and it fails the salt spray test. The experimental results using other metals exceed the standard values ​​by a large margin, and the performance is relatively stable. Therefore, the inventors selected a plating material containing one or more of gold, silver, silver-antimony alloy, graphite silver, graphene silver, palladium-nickel alloy, tin-lead alloy, or silver-gold-zirconium alloy.

[0113] Table 3 Effects of different coating materials on the plug-in and pull-out times and corrosion resistance of charging terminals:

[0114]

[0115] The second coating is made of a different material than the first coating. Different materials can be selected based on specific needs to control costs. In environments with low demand, lower-priced materials can be used as coatings. Different coatings can be selected based on specific needs. For example, a combination with higher conductivity or better corrosion resistance can be selected, or the combination that best suits the actual working environment can be selected after considering various factors.

[0116] This application also discloses a vehicle including the charging station described above. Not only is the manufacturing process simple and easy to manufacture, significantly reducing the processing time for the charging station, but if only the electrical connection device of the charging station is damaged during use, there is no need to dismantle the entire charging station and scrap the cables; only the charging terminal 2 needs to be removed. This simple and easy repair process consumes less time and has low repair costs, significantly reducing the cost and maintenance expenses of the vehicle disclosed in this application.

[0117] The above are only a few embodiments of the present application. Those skilled in the art may make various changes or modifications to the embodiments of the present application based on the contents disclosed in the application documents without departing from the spirit and scope of the present application.
