Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of charging port structures, and in particular, relates to a charging port anti-fouling structure and an electric loader. Background Art
[0002] Electric construction machinery has been widely used due to its advantages of energy saving and cost reduction, but at the same time it has also put forward higher requirements for high-power charging sockets.
[0003] Existing charging sockets often isolate impurities from the external environment by adding sealing components such as dust covers and anti-fouling slides. The sealing components are opened during charging and closed when charging is completed. However, the working environment and working conditions of electric loaders are relatively harsh, and the concentration of surrounding dust and other particulate matter is relatively high. The protective cover can only isolate part of the dust or oil. During the actual charging process, the dust or oil attached to the charging gun is still easily carried into the charging port and charging socket, and accumulated inside the charging seat, eventually causing the charging seat to fail or the temperature to rise uncontrollably during high-current charging.
[0004] In view of this, it is necessary to provide a new charging port anti-fouling structure and electric loader to solve the problem that dust or oil attached to the charging gun in the prior art is easily carried into the charging port and the charging socket, causing the charging port to be contaminated. Utility Model Content
[0005] In order to solve the problem that dust or oil attached to the charging gun in the prior art is easily carried into the charging port and the charging socket, causing the charging port to be contaminated, the utility model provides a new charging port anti-fouling structure and an electric loader. According to the first aspect of the utility model, the utility model provides a charging port anti-fouling structure, which is installed at the end of the charging port and is used to remove dirt from the charging gun, specifically including:
[0006] A sealing body, the sealing body is made of elastic material and includes a first anti-fouling part and a second anti-fouling part, wherein the first anti-fouling part and the second anti-fouling part are both interference-fitted with the charging gun;
[0007] A supporting frame is arranged inside the sealing body and close to the first anti-fouling part.
[0008] In one embodiment, the second anti-fouling portion is close to the end of the charging port, the first anti-fouling portion is far from the end of the charging port, and the charging gun passes through the first anti-fouling portion and the second anti-fouling portion in sequence and is inserted into the charging port.
[0009] In one embodiment, the interference between the second anti-fouling portion and the charging gun is not less than the interference between the first anti-fouling portion and the charging gun.
[0010] In one embodiment, the first anti-fouling portion forms a first contact angle with a contact surface of the charging gun, and the first contact angle is greater than 90 degrees.
[0011] In one embodiment, a gap is provided between the first anti-fouling portion and the second anti-fouling portion.
[0012] In one embodiment, the charging port anti-fouling structure further includes an annular elastic member, and the annular elastic member surrounds and abuts against the inner side of the second anti-fouling portion away from the contact surface with the charging gun.
[0013] In one embodiment, the annular elastic member is an annular spring connected end to end.
[0014] In one embodiment, the charging port anti-fouling structure is detachably installed at the end of the charging port.
[0015] In one embodiment, the supporting frame is made of metal.
[0016] According to a second aspect of the utility model, the utility model further provides an electric loader, which includes any one of the above-mentioned charging port anti-fouling structures.
[0017] According to the solution provided by the utility model, a separate anti-fouling structure for the charging port is provided and installed at the end of the charging port. When charging is required, the charging gun must first pass through the anti-fouling structure for the charging port before it can be inserted into the charging port. Furthermore, the anti-fouling structure for the charging port provided by the utility model includes a first anti-fouling portion and a second anti-fouling portion. Both the first anti-fouling portion and the second anti-fouling portion are made of elastic materials and are interference fit with the charging gun. Therefore, when the charging gun passes through the first anti-fouling portion and the second anti-fouling portion, the pollutants (particles, dust, oil, etc.) attached to the charging gun can be removed by the squeezing effect of the interference fit, and the pollutants are prevented from entering the charging port with the charging gun. Therefore, the solution provided by the utility model can solve the problem that dust or oil attached to the charging gun in the prior art is easily carried into the charging port and the charging socket, causing the charging port to be contaminated, and prevent the charging port or the charging socket from being contaminated and damaged by pollutants.
[0018] The electric loader provided by the utility model also has the above advantages because it includes the above anti-fouling structure of the charging port. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Please refer to Figure 1 and Figure 2 According to the first aspect of the utility model, the utility model provides a charging port anti-fouling structure, which is installed at the end of the charging port and is used to remove dirt from the charging gun, specifically comprising:
[0031] A sealing body, the sealing body is made of elastic material and includes a first anti-fouling part and a second anti-fouling part, wherein the first anti-fouling part and the second anti-fouling part are both interference-fitted with the charging gun;
[0032] A supporting frame is arranged inside the sealing body and close to the first anti-fouling part.
[0033] It should be noted that the anti-fouling structure of the charging port provided by the utility model is a relatively independent structure. When the charging port needs to be decontaminated, the anti-fouling structure can be installed on the charging port. When the decontamination function is not needed or the anti-fouling structure needs to be replaced, it can be disassembled. Of course, the anti-fouling structure of the charging port provided by the utility model can also be designed as an integrated structure with the charging port itself, and can be designed as needed. On the other hand, the anti-fouling structure of the charging port provided by the utility model must be compatible with the charging port so that it can be normally installed at the end of the charging port.
[0034] In this embodiment, the sealing body is an elastic material, and it is an elastic material with an insulating function to prevent problems such as conductive circuit breaking during charging. Specifically, taking into account the wear resistance, high temperature and chemical corrosion resistance of the material to provide long-term stable sealing performance, the material is preferably hydrogenated nitrile rubber to adapt to the high voltage working environment. The first anti-fouling part, the second anti-fouling part and the sealing body are an integrated structure, so the materials of the first anti-fouling part and the second anti-fouling part are the same as the sealing body, and both are elastic. Interference fit can be achieved between the first anti-fouling part, the second anti-fouling part and the charging gun, and the elasticity of the first anti-fouling part and the second anti-fouling part themselves is utilized to achieve a better decontamination effect.
[0035] In this embodiment, the support skeleton is arranged inside the sealing body and close to the first anti-fouling part. With such arrangement, on the one hand, it supports the sealing body as a whole, so that the sealing body can be more firmly installed at the end of the charging port. On the other hand, the support skeleton close to the first anti-fouling part can limit the excessive compression of the first anti-fouling part, that is, when the first anti-fouling part is squeezed by the charging gun, it can be compressed to the contact position with the support skeleton at most, which can prevent it from being damaged by excessive compression. It should be noted that the support skeleton is completely covered inside the sealing body and is fixed inside the sealing body and cannot be moved, so as to prevent the support skeleton from contacting with the charging gun or the charging port to form conductivity or damage the charging port; on the other hand, the sealing body as a whole is a hollow structure, and the hollow structure can provide the first anti-fouling part and the second anti-fouling part with a better compression space.
[0036] In this embodiment, during normal use, the charging port anti-fouling structure provided by the utility model needs to be installed at the end of the charging port first. When the charging gun is inserted for charging, it will first pass through the anti-fouling structure and then enter the inside of the charging port. The anti-fouling structure in this embodiment is provided with a first anti-fouling part and a second anti-fouling part, and both are interference fit with the charging gun. Therefore, when the charging gun is inserted into the anti-fouling structure, the first anti-fouling part and the second anti-fouling part can utilize the squeezing effect between the charging gun and the first anti-fouling part and the second anti-fouling part to perform two decontaminations of pollutants such as particles, dust, and oil attached to the surface of the charging gun, so as to prevent the pollutants carried by the charging gun from entering the charging socket.
[0037] Please refer to Figure 1 In one embodiment, the second anti-fouling part is close to the end of the charging port, the first anti-fouling part is far from the end of the charging port, and the charging gun passes through the first anti-fouling part and the second anti-fouling part in sequence and is inserted into the charging port. That is, when the charging gun is inserted into the anti-fouling structure, it contacts the first anti-fouling part first, and then contacts the second anti-fouling part, so that it can play a double decontamination role and improve the decontamination effect.
[0038] Please refer to Figure 1 In one embodiment, the interference between the second anti-fouling part and the charging gun is not less than the interference between the first anti-fouling part and the charging gun.
[0039] It should be noted that the interference refers to the difference between the shaft diameter of the charging gun and the inner diameter of the first anti-fouling part or the second anti-fouling part. The existence of the interference has two main functions: one is to compensate for the eccentricity between the sealing ring and the rotating shaft, and the other is to provide an initial load for the contact between the first anti-fouling part and the second anti-fouling part and the rotating shaft. If the interference is too large, dry friction with the charging gun is likely to occur, so that the temperature of the area where the first anti-fouling part or the second anti-fouling part contacts the charging gun is too high, which accelerates the aging of the anti-fouling part (sealing body) and the seal is prone to failure; if the interference is too small, when the sealing ring and the rotating shaft are eccentric or the rotating shaft beats, it is easy to cause leakage, reducing the sealing and decontamination effect. Specifically, the design of the interference needs to consider the applicable vehicle type and the size of the charging gun. Taking the electric loader as an example, it is preferred to set the interference of the first anti-fouling part to 0.09-0.15 mm and the interference of the second anti-fouling part to 0.3-0.8 mm.
[0040] In this embodiment, the interference between the second anti-fouling part and the charging gun is not less than the interference between the first anti-fouling part and the charging gun. In this way, the first anti-fouling part is mainly used to remove pollutants with larger particles, and the second anti-fouling part is mainly used to remove dust and even oil with smaller particles, which can not only achieve a better decontamination effect, but also extend the service life of the anti-fouling structure.
[0041] Please refer to Figure 2 In one embodiment, the first anti-fouling portion forms a first contact angle with a contact surface of the charging gun, and the first contact angle is greater than 90 degrees.
[0042] It should be noted that the contact angle refers to the angle formed between the first anti-fouling part and the contact surface of the charging gun. Figure 2 The figure is a schematic diagram of a cross section of the charging gun in the inserted state, where α is the first contact angle. On the other hand, the above embodiment has shown that the interference of the second anti-fouling part is not less than that of the first anti-fouling part. The first anti-fouling part is mainly used to remove pollutants with larger particles. In order to make the first anti-fouling part play a better role in removing pollutants, it is preferred to set the first contact angle to be greater than 90 degrees. In this way, the first anti-fouling part will play a role similar to "shoveling", which can improve its decontamination effect.
[0043] Please refer to Figure 1 In one embodiment, a gap is provided between the first anti-fouling part and the second anti-fouling part. The setting of the gap mainly plays a protective role to prevent the first anti-fouling part from being squeezed together with the second anti-fouling part and the charging gun after friction and being damaged due to insufficient compression space.
[0044] Please refer to Figure 1 In one embodiment, the charging port anti-fouling structure further includes an annular elastic member, which surrounds and abuts against the inner side of the second anti-fouling portion away from the contact surface with the charging gun.
[0045] In this embodiment, the setting of the annular elastic member can play a limiting role on the second anti-fouling part, similar to the limiting role of the support frame on the first anti-fouling part in the above embodiment, which can prevent the anti-fouling part from being excessively compressed and deformed. However, unlike the support frame, the annular elastic member has good elasticity, and when subjected to friction and compression, it allows the second anti-fouling part to expand radially. On the other hand, the annular elastic member can be fixedly installed at a position of the sealing body close to the second anti-fouling part by using its own elasticity, or it can be fixedly installed with the help of other tools, such as a clamping tool, a pasting tool, etc. The specific installation method can be set as needed.
[0046] It should be noted that there are many optional settings for the annular elastic member, as long as they can meet the above requirements, such as: an annular rubber ring, an annular spring connected end to end, etc. Preferably, considering cost and durability, the annular elastic member is an annular spring connected end to end.
[0047] Please refer to Figure 1 In one embodiment, the charging port anti-fouling structure can be detachably installed at the end of the charging port to facilitate replacement of the charging port anti-fouling structure.
[0048] Please refer to Figure 1 In one embodiment, the supporting frame is made of metal material, which has better durability and can increase the service life.
[0049] According to a second aspect of the utility model, the utility model further provides an electric loader, which includes the anti-fouling structure of the charging port in any of the above embodiments.
[0050] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
