Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a battery swapping connector with a composite wear-resistant and friction-reducing guiding structure. Background Technology

[0002] Battery swapping connectors are crucial components of new energy equipment. They typically consist of plug and socket modules that mate together. A guide pair made of the same metal is used to guide and align the plug and socket. However, this design has several drawbacks: First, the high coefficient of friction and low hardness of the same metal material lead to misalignment during insertion and removal under unbalanced external forces. This misalignment causes a sudden increase in friction, easily resulting in sticking, difficulty in insertion and removal, and accelerated wear. Long-term use may cause scratches on the inner surface of the guide sleeve, and the coefficient of friction further deteriorates with prolonged use, further increasing friction and affecting the connector's durability and insertion / removal efficiency. Second, reliance on external lubricants poses a risk of contamination and requires regular maintenance, increasing maintenance costs. Utility Model Content

[0003] To address one or more of the aforementioned problems, this utility model provides a battery swapping connector with a composite wear-resistant and friction-reducing guiding structure.

[0004] According to one aspect of the present invention, the battery swapping connector having a composite wear-resistant and friction-reducing guiding structure includes:

[0005] The plug body has two symmetrically arranged guide posts.

[0006] The socket body includes a floating shell and two composite guide sleeves, which are symmetrically and vertically sleeved on the left and right ends of the floating shell.

[0007] The composite guide sleeve includes a sleeve body and a composite guide ring. The composite guide ring is integrally connected to the inner wall or a local part of the inner wall of the sleeve body by sintering. The composite guide ring is formed by a combination of metal wear-resistant units and non-metal friction-reducing units with different materials from the guide post.

[0008] When the plug body and the socket body are connected, the guide post is inserted into the inner hole of the composite guide ring with a small gap. The non-metallic friction reduction unit reduces the insertion and extraction friction, and the metal wear-resistant unit reduces the friction insertion and extraction force and reduces wear.

[0009] In some embodiments, the inner wall of the sleeve body is formed into annular metal wear-resistant units by sintering metal powder, and the inner wall of the metal wear-resistant units is formed into annular non-metallic friction-reducing units by sintering non-metallic powder.

[0010] In some implementations, the composite guide sleeve has a non-uniformly distributed structure, and the thickness of the non-metallic friction reduction unit is increased at the force concentration inlet end of the sleeve body.

[0011] In some embodiments, at least one intermediate layer is provided between the metal wear-resistant unit and the non-metal friction-reducing unit, and the material of the intermediate layer has any one or more of the properties of transition, reinforcement and corrosion resistance.

[0012] In some embodiments, the intermediate layer is a graphite coating with transition properties;

[0013] Alternatively, the intermediate layer may be any one of nickel, chromium, and titanium layers, which have reinforcing and corrosion-resistant properties.

[0014] In some embodiments, the inner wall of the sleeve body is formed with a plurality of circumferentially distributed arc-shaped metal wear-resistant units by sintering metal powder, and between adjacent arc-shaped metal wear-resistant units, the inner wall of the sleeve body is formed with arc-shaped non-metallic friction-reducing units by sintering non-metallic powder.

[0015] In some embodiments, the inner wall of the sleeve body is formed with a plurality of vertically spaced, equally spaced annular metal wear-resistant units by sintering metal powder, and between adjacent annular metal wear-resistant units, the inner wall of the sleeve body is formed with annular non-metallic friction-reducing units by sintering non-metallic powder.

[0016] In some implementations, the metal wear-resistant unit is made of copper alloy material;

[0017] The non-metallic friction reduction unit is made of non-metallic materials with low friction coefficient or self-lubricating properties.

[0018] The main body of the set is made of black metal.

[0019] In some implementations, the metal wear-resistant unit is made of phosphor bronze or beryllium bronze;

[0020] Alternatively, the non-metallic friction-reducing unit may be made of polymer plastic or graphite.

[0021] Alternatively, the main body may be made of stainless steel.

[0022] In some embodiments, positioning shoulders are provided at the upper and lower ends of the inner wall of the sleeve body, and the two ends of the composite guide ring are attached to the positioning shoulders, and the inner diameters of the two are the same.

[0023] Alternatively, the upper entrance of the main body may also have a softened chamfer.

[0024] The advantages of this battery swapping connector with a composite wear-resistant and friction-reducing guiding structure are as follows: First, through the alignment of the composite guide sleeve and guide post, the composite guide sleeve has a metal wear-resistant unit and a non-metal friction-reducing unit made of different materials than the guide post. The friction coefficient between dissimilar materials is small, and the non-metal friction-reducing unit further reduces the friction coefficient. At the same time, the metal wear-resistant unit has high metal hardness, providing mechanical support and ensuring the strength of the structure. The two work together to significantly reduce the guiding friction during the insertion and removal process, resulting in smooth insertion and removal without jamming, effectively reducing wear and increasing service life. Second, the composite guide sleeve has a metal wear-resistant unit, which can reduce wear and increase friction, effectively ensuring the adaptability and durability of the connector. Third, the composite structure itself has a low friction coefficient, does not rely on external lubricants to reduce friction, has no risk of contamination, and reduces maintenance frequency and maintenance costs. Fourth, the two are sintered together on the sleeve body, resulting in a simple structure. The metal wear-resistant unit can also make good contact with the sleeve body components using its metallic properties, ensuring the strength of the structure. Attached Figure Description

[0034] Figures 1 to 6 A battery swapping connector with a composite wear-resistant and friction-reducing guiding structure according to an embodiment of the present invention is schematically shown. As shown, the battery swapping connector with the composite wear-resistant and friction-reducing guiding structure includes:

[0035] The plug body 01 has two guide posts 011 symmetrically arranged. Preferably, the lower end of the guide post 011 is provided with an inverted conical positioning end 012 and several rubber sealing rings 013 are installed in the middle section.

[0036] The socket body 02 includes a floating shell 1 and two composite guide sleeves 2, which are symmetrically and vertically sleeved on the left and right ends of the floating shell 1.

[0037] The composite guide sleeve 2 includes a sleeve body 21 and a composite guide ring 20. The composite guide ring 20 is integrally connected to the inner wall or a portion of the inner wall of the sleeve body 21 by sintering. The composite guide ring 20 is formed by combining a metal wear-resistant unit 22 and a non-metal friction-reducing unit 23, which are made of different materials than the guide post 011. Preferably, the metal wear-resistant unit 22 is made of copper alloy material, such as phosphor bronze or beryllium bronze; the non-metal friction-reducing unit 23 is made of a non-metallic material with a low coefficient of friction or a self-lubricating non-metallic material, such as polymer plastic or graphite; and the sleeve body 21 is made of ferrous metal material, such as stainless steel.

[0038] When the plug body 01 and the socket body 02 are connected, the guide post 011 is inserted into the inner hole of the composite guide ring 20 with a small gap, the non-metallic friction reduction unit 23 reduces the insertion and extraction friction, and the metal wear-resistant unit 22 reduces the friction insertion and extraction force and reduces wear.

[0039] The beneficial effects of this battery swapping connector with a composite wear-resistant and friction-reducing guiding structure are as follows: First, the composite guide sleeve 2 and guide post 011 are matched and aligned. The composite guide sleeve 2 has a metal wear-resistant unit 22 and a non-metal friction-reducing unit 23, which are of different materials from the guide post 011. The friction coefficient between the different materials is small, and the non-metal friction-reducing unit 23 further reduces the friction coefficient. At the same time, the metal wear-resistant unit 22 has high metal hardness, which provides mechanical support and ensures the strength of the structure. The two work together to significantly reduce the guiding friction during the insertion and removal process, making insertion and removal smooth and without jamming, effectively reducing wear and increasing service life. Second, the composite guide sleeve 2 has a metal wear-resistant unit 22, which can reduce wear and increase friction, effectively ensuring the adaptability and durability of the connector. Third, the composite structure itself has a low friction coefficient, does not rely on external lubricants to reduce friction, has no risk of contamination, and reduces maintenance frequency and maintenance costs. Fourth, the two are sintered together on the sleeve body 21, which is simple in structure. The metal wear-resistant unit 22 can also make good contact with the sleeve body 21 components by utilizing its metal properties, ensuring the strength of the structure.

[0040] Furthermore, the composite guide ring 20 has an inner and outer nested structure. The inner wall of the sleeve body 21 is formed by sintering metal powder to form a ring-shaped metal wear-resistant unit 22, and the inner wall of the metal wear-resistant unit 22 is formed by sintering non-metallic powder to form a ring-shaped non-metallic friction-reducing unit 23. Its advantages are: this structure is easy to manufacture; the metal wear-resistant unit 22 provides stable mechanical support, ensuring that the friction-reducing structure layer will not easily deform or be damaged during insertion and removal; and the non-metallic friction-reducing unit 23 has low-friction contact, significantly reducing insertion friction.

[0041] Preferably, the composite guide sleeve 2 has a non-uniformly distributed structure, and the thickness of the non-metallic friction-reducing unit 23 is increased at the force-concentrated inlet end of the sleeve body 21. Its beneficial effect is that by adopting an asymmetric composite layer distribution, it specifically reduces local friction peaks, achieving smooth, jam-free insertion and removal.

[0042] Furthermore, at least one intermediate layer 24 is provided between the metal wear-resistant unit 22 and the non-metal friction-reducing unit 23. The material of the intermediate layer 24 has any one or more of the following properties: transition, reinforcement, and corrosion resistance. This arrangement is suitable for a variety of application environments.

[0043] Preferably, the intermediate layer 24 is a graphite coating with transition properties. Its beneficial effects are: to enhance the bonding force between the metallic and non-metallic material layers, while further improving friction-reducing properties.

[0044] Preferably, the intermediate layer 24 is any one of a nickel layer, a chromium layer, and a titanium layer, which have enhancing and corrosion-resistant properties. Its advantages are that this configuration is suitable for applications involving corrosion and high friction.

[0045] Furthermore, the composite guide ring 20 has a circumferentially distributed structure. The inner wall of the sleeve body 21 is formed with several circumferentially distributed arc-shaped metal wear-resistant units 22 by sintering metal powder. Between adjacent arc-shaped metal wear-resistant units 22, the inner wall of the sleeve body 21 is formed with arc-shaped non-metallic friction-reducing units 23 by sintering non-metallic powder. The vertical end faces of the metal wear-resistant units 22 and the non-metallic friction-reducing units 23 are integrally connected, and their inner arc surfaces are integrally connected to form the inner ring wall of the composite guide ring 20. Its beneficial effects are: this design can simultaneously achieve high wear resistance and friction reduction, ensure smooth insertion and removal without jamming, and increase service life.

[0046] Furthermore, the composite guide ring 20 has a vertically equidistant distribution structure. The inner wall of the sleeve body 21 is formed with sintered metal powder to create several vertically equidistant circular metal wear-resistant units 22. Between adjacent circular metal wear-resistant units 22, the inner wall of the sleeve body 21 is formed with sintered non-metallic powder to create circular non-metallic friction-reducing units 23. The horizontal end faces of the metal wear-resistant units 22 and the non-metallic friction-reducing units 23 are integrally connected, and their inner arc surfaces are integrally connected to form the inner ring wall of the composite guide ring 20. The beneficial effects are: this design simultaneously provides high wear resistance and friction reduction, ensures smooth insertion and removal without jamming, and increases service life.

[0047] Furthermore, the inner wall of the sleeve body 21 is provided with positioning shoulders 25 at both ends, and the two ends of the composite guide ring 20 are attached to the positioning shoulders 25, and the inner diameters of the two are the same; the beneficial effect is that this setting can improve the product accuracy.

[0048] Preferably, a small-diameter positioning ring 26 is integrally connected to the lower end of the sleeve body 21; its advantage is that this setting facilitates high-precision assembly.

[0049] Preferably, the upper inlet of the sleeve body 21 is also provided with a softened chamfer 27. The beneficial effect is that this setting can effectively reduce insertion and extraction resistance.

[0050] Furthermore, the floating shell 1 has a socket in the middle that matches the plug terminal of the plug body 01. The lower end of the floating shell 1 is located inside the outer shell 3. It is connected to the lower wall of the outer shell 3 through a vertical elastic floating component and to the side wall of the outer shell 3 through an XY plane elastic floating component.
