Description

Battery swapping connectors and electrical equipment Technical Field

[0001] This application relates to the field of battery swapping connector technology, and in particular to a battery swapping connector and electrical equipment. Background Technology

[0002] When electrical equipment is connected to a power source such as a battery, a battery swapping connector is required. Generally, battery swapping connectors have a certain degree of float capability to absorb errors that occur during the battery swapping process.

[0003] Currently, battery swapping connectors with floating functionality generally include a fixed component and a floating component. During the battery swapping process, the floating component directly contacts and rubs against the fixed component. The metal shavings generated after friction can easily accumulate inside the battery swapping connector and cause short circuits, thus affecting the service life of the battery swapping connector.

[0004] Summary of the Invention

[0005] In view of the deficiencies of the prior art, the purpose of this application is to provide a battery swapping connector and electrical equipment, which can effectively solve the problem of metal shavings generated by the friction between the floating part and the fixed part of the battery swapping connector.

[0006] The first aspect of this application discloses a battery swapping connector, comprising:

[0007] Fasteners;

[0008] A floating component is connected to a fixed component in a manner that allows it to float relative to the fixed component along a first direction;

[0009] The fastener has a first surface facing the floating member along the second direction, the floating member has a second surface facing the fastener along the second direction, at least one of the first surface and the second surface is provided with a wear-resistant layer, the first surface and the second surface abut against each other through the wear-resistant layer, and the second direction is set at an angle to the first direction.

[0010] According to the battery swapping connector of this application, the floating member can float relative to the fixed member along a first direction, thereby absorbing the error generated along the first direction during the battery swapping connection. During the floating process along the first direction, the floating member abuts against the fixed member through a wear-resistant layer. Due to the setting of the wear-resistant layer, the metal shavings generated by the mutual friction between the floating member and the fixed member can be reduced, thereby reducing the accumulation of metal shavings inside the battery swapping connector and thus reducing the occurrence of internal short circuits in the battery swapping connector.

[0011] In some embodiments of this application, the coefficient of friction of the wear-resistant layer is less than the coefficient of friction of either the first surface or the second surface.

[0012] By making the friction coefficient of the wear-resistant layer smaller than that of either the first surface or the second surface, the friction between the first surface and the second surface can be reduced, thereby reducing wear between the first surface and the second surface and reducing the generation of metal shavings.

[0013] In some embodiments of this application, the wear-resistant layer includes a non-metallic wear-resistant layer.

[0014] By setting the wear-resistant layer to a non-metallic wear-resistant layer, even if the wear-resistant layer wears during the relative floating process between the floating and fixed parts, the resulting debris will be non-metallic debris, thereby reducing the occurrence of internal short circuits in the battery swapping connector.

[0015] In some embodiments of this application, the friction coefficient of the wear-resistant layer ranges from 0.05 mm. 3 / N·m to 0.3mm 3 / N·m.

[0016] By setting the friction coefficient range of the wear-resistant layer to 0.05mm 3 The abrasion resistance of the wear-resistant layer can be improved from 0.3 mm3 / N·m to 0.3 mm3 / N·m, thereby reducing the contact between the first and second surfaces caused by wear of the wear-resistant layer, and further reducing the metal shavings generated by the mutual friction between the first and second surfaces.

[0017] In some embodiments of this application, the thickness of the wear-resistant layer ranges from 0.5 μm to 2.5 mm.

[0018] By setting the thickness range of the wear-resistant layer to 0.5µm to 2.5mm, the thickness of the wear-resistant layer can be increased, thereby reducing the contact between the first and second surfaces caused by wear of the wear-resistant layer, and thus reducing the metal shavings generated by the mutual friction between the first and second surfaces.

[0019] In some embodiments of this application, the wear-resistant layer includes a wear-resistant coating disposed on at least one of the first surface and the second surface.

[0020] The wear-resistant layer may include a wear-resistant coating and is formed on at least one of the first and second surfaces, having good wear resistance and being easy to manufacture.

[0021] In some embodiments of this application, the wear-resistant layer includes at least one of a PTFE coating and a PA11 coating.

[0022] PTFE coating, PA11 coating, PDS coating and PTFE coating are common coatings that have good wear resistance and are easy to manufacture.

[0023] In some embodiments of this application, the wear-resistant layer includes a layered structure bonded to at least one of the first surface and the second surface.

[0024] The wear-resistant layer may include a layered structure and be bonded to at least one of the first and second surfaces by means of adhesive bonding, thereby improving the fixing strength of the wear-resistant layer and reducing the phenomenon of wear-resistant layer falling off.

[0025] In some embodiments of this application, the wear-resistant layer includes at least one of a PA layer, a POM layer, an ultra-high molecular weight polyethylene layer, and a PTFE layer.

[0026] PA layer, POM layer, ultra-high molecular weight polyethylene layer and PTFE layer are common wear-resistant layer materials, which have good wear resistance and are easy to manufacture.

[0027] In some embodiments of this application, the wear-resistant layer includes a first wear-resistant layer disposed on the second surface, and the first wear-resistant layer has a first arcuate surface protruding toward the first surface along the second direction.

[0028] By providing a first arc-shaped surface protruding toward the first surface in the second direction on the first wear-resistant layer, the first arc-shaped surface can reduce the friction between the floating part and the fixed part during the floating process of the floating part relative to the fixed part, thereby reducing the metal chips generated by the fixed part due to friction.

[0029] In some embodiments of this application, the wear-resistant layer includes a second wear-resistant layer, which is disposed on the first surface and has a second arcuate surface recessed away from the first wear-resistant layer along a second direction, with the first arcuate surface abutting against the second arcuate surface.

[0030] By providing a second arc-shaped surface that is recessed away from the first wear-resistant layer along a second direction on the second wear-resistant layer, and the first arc-shaped surface abutting against the second arc-shaped surface, the friction between the first wear-resistant layer and the second wear-resistant layer can be reduced during the floating process of the floating part relative to the fixed part, thereby reducing the wear of the first wear-resistant layer and the second wear-resistant layer and improving the service life of the first wear-resistant layer and the second wear-resistant layer.

[0031] In some embodiments of this application, the battery swapping connector further includes a first elastic member for connecting the fixed member and the floating member, the first elastic member being configured to extend and retract along a first direction.

[0032] Since the first elastic element can extend and retract along the first direction, the fixed element and the floating element connected by the first elastic element can float and connect along the first direction, thereby absorbing the error generated along the first direction during the battery swapping connection process.

[0033] In some embodiments of this application, the battery swapping connector further includes a second elastic element for connecting the fixed element and the floating element, the second elastic element being configured to extend and retract along a second direction.

[0034] Since the second elastic element can extend and retract along the second direction, the fixed and floating parts connected by the second elastic element can float and connect along the second direction, thereby absorbing the error generated along the second direction during the battery swapping connection process.

[0035] In some embodiments of this application, the floating member includes a housing and a first protruding end disposed outside the housing. The housing is connected to the fixing member through a first elastic member. The first protruding end is provided with a second surface and a third surface disposed along a second direction opposite to the second surface. The second elastic member is disposed between the third surface and the fixing member.

[0036] Since the second and third surfaces are respectively located on opposite sides of the first protruding end along the second direction, by placing the second elastic element between the third surface and the fixed element, the first protruding end abuts against the first surface through the wear-resistant layer under the elastic force of the second elastic element, that is, the second surface abuts against the first surface through the wear-resistant layer, thereby limiting the floating element along the second direction and reducing the metal chips generated by the direct friction between the first and second surfaces during the floating process of the floating element along the first direction.

[0037] In some embodiments of this application, the fixing member has a first opening extending through it in a second direction, and the floating member has a plug-in terminal and a wire harness electrically connected to the plug-in terminal. The plug-in terminal passes through the first opening, and the first direction is consistent with the plugging direction of the wire harness.

[0038] The floating component can be connected to the battery device via a wiring harness. The plug-in terminals of the floating component can be inserted through the first opening and electrically connected to the power-consuming component, thereby enabling power supply to the power-consuming component.

[0039] In some embodiments of this application, the fastener includes a support portion disposed at the edge of the first opening, and the support portion has a first surface.

[0040] By providing a support portion at the edge of the first opening and providing a first surface facing the floating member on the support portion, it is convenient to support the floating member through the first surface and to make the first surface and the second surface abut against each other through the wear-resistant layer.

[0041] The second aspect of this application provides an electrical device that includes a power swapping connector as described above.

[0042] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0062] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0063] It should be noted that, unless otherwise stated, the technical or scientific terms used in the embodiments of this application shall have the ordinary meaning as understood by those skilled in the art to which the embodiments of this application pertain.

[0064] In the description of the embodiments of this application, the technical terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and other terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0065] Furthermore, technical terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of embodiments of this application, "a plurality of" means two or more, unless otherwise explicitly defined.

[0066] In the description of the embodiments of this application, unless otherwise explicitly specified and limited, the technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0067] In the description of the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0068] Batteries, as energy storage devices, are widely used to power electrical equipment such as electric vehicles. To power the motor, which is the driving force of the electric vehicle, and other electrical components within the vehicle, the battery needs to be connected to the motor or other electrical components. Furthermore, to enable quick and convenient battery replacement, battery swapping connectors are typically provided on both the output harness (which receives power from the battery) and the input harness (which receives power from the motor or other electrical components; in the following description, unless otherwise specified, they are sometimes collectively referred to as harnesses). By inserting and removing these connectors, the output harness and input harness are connected and disconnected, thus completing the replacement of the old battery with the new one.

[0069] Due to factors such as battery installation location and wiring harness length, there are certain assembly errors during battery replacement when inserting and removing the input and output wiring harness connectors. Therefore, current battery replacement connectors with floating functionality generally include a fixed component and a floating component. During battery replacement, the floating component directly abuts and rubs against the fixed component. The resulting metal shavings can easily accumulate inside the connector, causing short circuits and affecting its lifespan.

[0070] Based on the above considerations, in order to solve the problem of metal shavings generated by the friction between the floating part and the fixed part of the battery swapping connector, this application proposes a battery swapping connector and an electrical device having the battery swapping connector. According to the battery swapping connector and electrical device of this application, the metal shavings generated by the mutual friction between the floating part and the fixed part can be reduced, thereby reducing the accumulation of metal shavings inside the battery swapping connector and thus reducing the occurrence of internal short circuits in the battery swapping connector.

[0071] The battery swapping connector can be connected to a battery to output power from the battery, or it can be connected to an electrical device to supply power from the battery to the device. For ease of description, the embodiments of this application will only be described using the example of the battery swapping connector being connected to an electrical device, such as a battery swapping connector being connected to a vehicle and used to supply power from the battery to the vehicle's motor.

[0072] Figure 1 is a structural schematic diagram of a vehicle 1000 provided in some embodiments of this application. As shown in Figure 1, the vehicle 1000 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. A battery 100 is disposed inside the vehicle 1000, and the battery 100 can be located at the bottom, front, or rear of the vehicle 1000. The battery 100 can be used to power the vehicle 1000; for example, the battery 100 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery 100 to supply power to the motor 300, for example, to meet the power requirements of the vehicle 1000 during startup, navigation, and driving.

[0073] In some embodiments of this application, the battery 100 can not only serve as the operating power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0074] Referring to Figures 1 to 8, a first aspect of this application proposes a battery swapping connector 1, which includes a fixing member 10 and a floating member 20. The floating member 20 is connected to the fixing member 10 in a floating manner relative to the fixing member 10 along a first direction X. The fixing member 10 has a first surface 141 facing the floating member 20 along a second direction Y, and the floating member 20 has a second surface 221 facing the fixing member 10 along the second direction Y. At least one of the first surface 141 and the second surface 221 is provided with a wear-resistant layer 30. The first surface 141 and the second surface 221 abut against each other through the wear-resistant layer 30. The second direction Y is set at an angle to the first direction X.

[0075] Specifically, the fixing member 10 can be used to fix and install on electrical equipment, which can be a vehicle 1000, and the fixing member 10 can be installed on the motor 300 of the vehicle 1000. The floating member 20 is connected to the fixing member 10 in a manner that allows it to float along a first direction X, thereby allowing the floating member 20 to absorb errors generated along the first direction X during the insertion and removal of the wiring harness 25. The insertion and removal process of the wiring harness 25 is the process of the power swapping connection of the power swapping connector 1. The first direction X can be the insertion and removal direction of the wiring harness 25. In this application, "floating" means that two components are connected by a connector and can move relatively within a certain range without completely separating.

[0076] The floating member 20 is mounted on the fixing member 10. The fixing member 10 has a first surface 141 facing the floating member 20 along the second direction Y, and the first surface 141 is used to support the floating member 20. The floating member 20 has a second surface 221 facing the fixing member 10 along the second direction Y, and the first surface 141 and the second surface 221 are arranged opposite to each other along the second direction Y. The second direction Y is angled with the first direction X, and optionally, the second direction Y is perpendicular to the first direction X.

[0077] In conventional solutions, the first surface 141 and the second surface 221 abut against each other along the second direction Y, and during the battery swapping connection of the battery swapping connector 1, they move relative to each other along the first direction Y and rub against each other, thereby generating debris. When at least one of the first surface 141 and the second surface 221 is a metal part, metal shavings will be generated during the friction between the first surface 141 and the second surface 221, which can easily lead to a short circuit inside the battery swapping connector 1. In this application, to reduce the short circuit inside the battery swapping connector caused by the generation of metal shavings, at least one of the first surface 141 and the second surface 221 is provided with a wear-resistant layer 30. This includes one of the first surface 141 and the second surface 221 being provided with a wear-resistant layer 30, or both the first surface 141 and the second surface 221 being provided with a wear-resistant layer 30. Since a wear-resistant layer 30 is provided between the first surface 141 and the second surface 221, the first surface 141 and the second surface 221 abut against each other through the wear-resistant layer 30, thereby reducing the metal shavings generated by the direct friction between the first surface 141 and the second surface 221, and thus reducing the internal short circuit phenomenon of the battery swapping connector 1.

[0078] Optionally, the fixing member 10 includes a support plate 11, which is generally plate-shaped. The floating member 20 is disposed on one side of the support plate 11 along the second direction Y. The support plate 11 has a first surface 141 facing the floating member 20 along the second direction Y, and the floating member 20 has a second surface 221 facing the support plate 11 along the second direction Y. The second direction Y is perpendicular to the plate surface of the support plate 11. The fixing member 10 also includes two side plates 12, which are disposed at both ends of the support plate 11 along a third direction Z and connected to the support plate 11. The third direction Z is perpendicular to the first direction X and the second direction Y, respectively. The support plate 11 and the two side plates 12 together form a generally groove-shaped structure. Part of the floating member 20 is disposed within the groove-shaped structure, thereby protecting the floating member 20 inside through the support plate 11 and the side plates 12. The groove-shaped structure has open ends at both ends along the first direction X, through which the wire harness 25 can pass and connect to the battery 100.

[0079] According to the battery swapping connector 1 of this application, the floating member 20 can float relative to the fixed member 10 along the first direction X, thereby absorbing the error generated along the first direction X during the battery swapping connection process. During the floating process along the first direction X, the floating member 20 abuts against the fixed member 10 through the wear-resistant layer 30. Due to the provision of the wear-resistant layer 30, the metal shavings generated by the mutual friction between the floating member 20 and the fixed member 10 can be reduced, thereby reducing the accumulation of metal shavings inside the battery swapping connector 1 and thus reducing the occurrence of internal short circuits in the battery swapping connector 1.

[0080] Referring to Figures 1 to 8, in some embodiments of this application, the coefficient of friction of the wear-resistant layer 30 is less than the coefficient of friction of either the first surface 141 or the second surface 221.

[0081] Specifically, the lower the coefficient of friction, the better the wear resistance. The coefficient of friction of the wear-resistant layer 30 is lower than that of the first surface 141, and the coefficient of friction of the wear-resistant layer 30 is also lower than that of the second surface 221.

[0082] By making the friction coefficient of the wear-resistant layer 30 less than that of either the first surface 141 or the second surface 221, the friction between the first surface 141 and the second surface 221 can be reduced, thereby reducing wear between the first surface 141 and the second surface 221 and reducing the generation of metal shavings.

[0083] Referring to Figures 2 to 8, in some embodiments of this application, the wear-resistant layer 30 includes a non-metallic wear-resistant layer.

[0084] Specifically, the non-metallic wear-resistant layer includes at least one of ceramic composite materials, silicon carbide (SiC), and silicon nitride (Si3N4).

[0085] By setting the wear-resistant layer 30 as a non-metallic wear-resistant layer, even if the wear-resistant layer 30 wears during the relative floating process between the floating part 20 and the fixed part 10, the generated debris will be non-metallic debris, thereby reducing the occurrence of internal short circuits in the battery swapping connector 1.

[0086] Referring to Figures 2 to 8, in some embodiments of this application, the friction coefficient of the wear-resistant layer 30 ranges from 0.05 mm. 3 / N·m to 0.3mm 3 / N·m. Where mm 3 The value represents the volume of wear, N represents the force unit Newton, and m represents the distance unit meter.

[0087] Specifically, the coefficient of friction of the wear-resistant layer 30 can be 0.05 mm. 3 / N·m…0.1mm 3 / N·m…0.2mm 3 / N·m…0.3mm 3 Any value in / N·m. The coefficient of friction is one of the important indicators for measuring the wear resistance of a material. Simply put, the coefficient of friction refers to the volume or mass of wear on the surface of a material under unit pressure and unit distance. The higher the coefficient of friction, the better the wear resistance of the material.

[0088] By setting the friction coefficient range of the wear-resistant layer 30 to 0.05 mm 3 / N·m to 0.3mm 3 / N·m can improve the wear resistance of the wear-resistant layer 30, thereby reducing the contact between the first surface 141 and the second surface 221 caused by the wear of the wear-resistant layer 30, and further reducing the metal shavings generated by the mutual friction between the first surface 141 and the second surface 221.

[0089] Referring to Figures 2 to 8, in some embodiments of this application, the thickness of the wear-resistant layer 30 ranges from 0.5 μm to 2.5 mm.

[0090] Specifically, the thickness of the wear-resistant layer 30 can be any value among 0.5um…10um…100um…1mm…2.5mm.

[0091] By setting the thickness range of the wear-resistant layer 30 to 0.5 μm to 2.5 mm, the thickness of the wear-resistant layer 30 can be increased, thereby reducing the contact between the first surface 141 and the second surface 221 caused by the wear of the wear-resistant layer 30, and further reducing the metal shavings generated by the mutual friction between the first surface 141 and the second surface 221.

[0092] Referring to Figures 2 to 8, in some embodiments of this application, the wear-resistant layer 30 includes a wear-resistant coating disposed on at least one of the first surface 141 and the second surface 221.

[0093] Specifically, a wear-resistant coating is a substrate coated with a non-stick coating that has friction resistance, including thermally sprayed wear-resistant coatings and chemically bonded wear-resistant coatings. Wear-resistant coatings formed by spraying ceramics, alloys, oxides, fluoroplastics, etc., onto metal surfaces using plasma spraying, arc spraying, or flame spraying are generally called thermally sprayed wear-resistant coatings. Wear-resistant coatings obtained by applying wear-resistant coating adhesives formulated with various resins and elastomers to metal surfaces and then allowing them to cure naturally or by heating are called chemically bonded wear-resistant coatings.

[0094] The wear-resistant layer may include a wear-resistant coating and is formed on at least one of the first surface 141 and the second surface 221, having good wear resistance and being easy to manufacture.

[0095] Referring to Figures 2 to 8, in some embodiments of this application, the wear-resistant layer 30 includes at least one of a PTFE (Poly Tetra Fluoro Ethylene) coating and a PA11 (Poly Amide 11) coating.

[0096] PTFE coating, PA11 coating, PDS coating and PTFE coating are common coatings that have good wear resistance and are easy to manufacture.

[0097] Referring to Figures 2 to 8, in some embodiments of this application, the wear-resistant layer 30 includes a layered structure bonded to at least one of the first surface 141 and the second surface 221.

[0098] Specifically, the wear-resistant layer 30 is an independent layered structure and is bonded to one of the first surface 141 and the second surface 221 by means of adhesive bonding.

[0099] The wear-resistant layer 30 may include a layered structure and is bonded to at least one of the first surface 141 and the second surface 221 by means of adhesion, thereby improving the fixing strength of the wear-resistant layer 30 and reducing the phenomenon of wear-resistant layer 30 falling off.

[0100] Referring to Figures 2 to 8, in some embodiments of this application, the wear-resistant layer 30 includes at least one of a PA (Poly, nylon) layer, a POM (Poly Oxy Methylene) layer, an ultra-high molecular weight polyethylene layer, and a PTFE (Poly Tetra Fluoro Ethylene) layer.

[0101] PA layer, POM layer, ultra-high molecular weight polyethylene layer and PTFE layer are common wear-resistant layer materials, which have good wear resistance and are easy to manufacture.

[0102] Referring to Figures 2 to 8, in some embodiments of this application, the wear-resistant layer 30 includes a first wear-resistant layer 31, which is disposed on the second surface 221, and the first wear-resistant layer 31 has a first arcuate surface protruding toward the first surface 141 along the second direction Y.

[0103] Specifically, the wear-resistant layer 30 includes a first wear-resistant layer 31 disposed on the second surface 221. The first wear-resistant layer 31 floats together with the floating member 20 and is used to abut against the first surface 141. The first wear-resistant layer 31 has a first arc-shaped surface protruding towards the second surface 221 along the second direction Y. During the battery swapping connection process of the battery swapping connector 1, compared to flat contact, the friction between the first arc-shaped surface and the first surface 141 is smaller, facilitating the floating of the floating member 20. Simultaneously, only a portion of the first arc-shaped surface abuts against the first surface 141, thereby reducing wear on the first wear-resistant layer 31.

[0104] By providing a first arc-shaped surface protruding along the second direction Y toward the first surface 141 on the first wear-resistant layer 31, the first arc-shaped surface can reduce the friction between the floating member 20 and the fixed member 10 during the floating process of the floating member 20 relative to the fixed member 10, thereby reducing the metal chips generated by the fixed member 10 due to friction.

[0105] Referring to Figures 2 to 8, in some embodiments of this application, the wear-resistant layer 30 includes a second wear-resistant layer 32, which is disposed on the first surface 141, and the second wear-resistant layer 32 has a second arcuate surface that is recessed away from the first wear-resistant layer 31 along the second direction Y, and the first arcuate surface abuts against the second arcuate surface.

[0106] Specifically, the wear-resistant layer 30 further includes a second wear-resistant layer 32 disposed on the first surface 141, with the first wear-resistant layer 31 abutting against the second wear-resistant layer 32. The second wear-resistant layer 32 has a second arc-shaped surface recessed away from the second surface 221 along the second direction Y, thus adapting to the protruding first arc-shaped surface. During the battery swapping connection process of the battery swapping connector 1, compared to a flat contact, the friction between the first arc-shaped surface and the second arc-shaped surface is smaller, facilitating the floating of the floating member 20. Simultaneously, only a portion of the first arc-shaped surface abuts against a portion of the second arc-shaped surface, thereby reducing wear on the first wear-resistant layer 31 and the second wear-resistant layer 32.

[0107] By providing a second arc-shaped surface recessed in the second direction Y away from the first wear-resistant layer 31 on the second wear-resistant layer 32, and the first arc-shaped surface abutting against the second arc-shaped surface, the friction between the first wear-resistant layer 31 and the second wear-resistant layer 32 can be reduced during the floating process of the floating member 20 relative to the fixed member 10, thereby reducing the wear of the first wear-resistant layer 31 and the second wear-resistant layer 32 and improving the service life of the first wear-resistant layer 31 and the second wear-resistant layer 32.

[0108] Referring to Figures 2 to 8, in some embodiments of this application, the battery swapping connector 1 further includes a first elastic member 40 for connecting the fixing member 10 and the floating member 20, the first elastic member 40 being configured to extend and retract along a first direction X.

[0109] Specifically, the first elastic element 40 is connected to the fixed element 10 and the floating element 20 at its two ends along its own elastic deformation, thereby facilitating the floating element 20 to float and connect with the fixed element 10 along the first direction X via the first elastic element 40. The elastic deformation direction of the first elastic element 40 can be parallel to the axis of the wire harness 25. Alternatively, the elastic deformation direction of the first elastic element 40 can be at an angle greater than 0° and less than 90° to the axis of the wire harness 25, thus having a deformation amount along the first direction X during the elastic deformation process of the first elastic element 40. Optionally, the elastic deformation direction of the first elastic element 40 is parallel to the surface of the support plate 11 and at an angle greater than 0° and less than 90° to the axis of the wire harness 25, thus having a deformation amount along the first direction X and a deformation amount along a third direction Z during the elastic deformation process of the first elastic element 40.

[0110] Optionally, the first elastic element 40 is a spring. The floating element 20 is provided with a first mounting portion 23, and the fixed element 10 is provided with a second mounting portion 15, with the first mounting portion 23 and the second mounting portion 15 respectively having connecting protrusions. The first elastic element 40 is hooked onto the connecting protrusions of the first mounting portion 23 and the second mounting portion 15 at both ends along its own elastic deformation, thereby floatingly connecting the fixed element 10 and the floating element 20 along the first direction X.

[0111] Since the first elastic element 40 can extend and retract along the first direction X, the fixed element 10 and the floating element 20 connected by the first elastic element 40 can float and connect along the first direction X, thereby absorbing the error generated along the first direction X during the battery swapping connection process.

[0112] Referring to Figures 2 to 8, in some embodiments of this application, the battery swapping connector 1 further includes a second elastic member 50 for connecting the fixing member 10 and the floating member 20, the second elastic member 50 being configured to extend and retract along a second direction Y.

[0113] Specifically, the two ends of the second elastic member 50 along its own elastic deformation are connected to the fixed member 10 and the floating member 20 respectively, so that the floating member 20 can be floatingly connected to the fixed member 10 along the second direction Y through the second elastic member 50.

[0114] Optionally, the second elastic element 50 is a spring. The floating element 20 is provided with a first support protrusion 223, and the fixed element 10 is provided with a second support protrusion 131. The two ends of the second elastic element 50 along its own elastic deformation are respectively sleeved on the outside of the first support protrusion 223 and the second support protrusion 131, thereby floatingly connecting the fixed element 10 and the floating element 20 along the second direction Y.

[0115] Since the second elastic member 50 can extend and retract along the second direction Y, the fixed member 10 and the floating member 20 connected by the second elastic member 50 can float and connect along the second direction Y, thereby absorbing the error generated along the second direction Y during the battery swapping connection process.

[0116] Referring to Figures 2 to 8, in some embodiments of this application, the floating member 20 includes a housing 21 and a first protruding end 22 disposed outside the housing 21.

The first protruding end 22 is also provided with a third surface 222 disposed in the second direction Y opposite to the second surface 221. The second elastic member 50 is disposed between the third surface 222 and the fixing member 10.

[0117] Specifically, the floating member 20 includes a housing 21, and the outer side wall of the housing 21 is provided with a first mounting portion 23. There can be multiple first mounting portions 23, spaced apart and arranged in a ring around the outer side wall of the housing 21. The side plate 12 of the fixing member 10 has a second mounting portion 15 at the end away from the support plate 11. The first mounting portion 23 and the second mounting portion 15 are respectively provided with connecting protrusions. The first elastic member 40, along its own elastic deformation, is respectively hooked onto the connecting protrusions of the first mounting portion 23 and the second mounting portion 15, thereby floatingly connecting the fixing member 10 and the floating member 20 along the first direction X.

[0118] The outer wall of the housing 21 is also provided with a first protruding end 22. There can be multiple first protruding ends 22, which are spaced apart and arranged in a ring around the outer wall of the housing 21. The surface of the first protruding end 22 facing the support plate 11 along the second direction Y is the second surface 221. The first protruding end 22 is also provided with a third surface 222 arranged in the opposite direction to the second surface 221 along the second direction Y. The second elastic member 50 is disposed between the third surface 222 and the fixing member 10, and the floating member 20 abuts against the first surface 141 through the wear-resistant layer 30 under the elastic force of the second elastic member 50.

[0119] Optionally, the third surface 222 has a first support protrusion 223 protruding outwards. The side plate 12 has a second protruding end 13 at one end opposite to the support plate 11, and the second protruding end 13 is spaced apart from the support plate 11 along the second direction Y. The second protruding end 13 has a second support protrusion 131 protruding towards the support plate 11. When the second elastic member 50 is a spring, both ends of the second elastic member 50 are respectively sleeved on the outside of the first support protrusion 223 and the second support protrusion 131, thereby allowing the fixed member 10 and the floating member 20 to float and connect along the second direction Y via the second elastic member 50.

[0120] Since the second surface 221 and the third surface 222 are respectively located on opposite sides of the first protruding end 22 along the second direction Y, by placing the second elastic member 50 between the third surface 222 and the fixing member 10, the first protruding end 22 abuts against the first surface 141 through the wear-resistant layer 30 under the elastic force of the second elastic member 50, that is, the second surface 221 abuts against the first surface 141 through the wear-resistant layer 30, thereby limiting the floating member 20 along the second direction Y, and reducing the metal chips generated by the direct friction between the first surface 141 and the second surface 221 during the floating process of the floating member 20 along the first direction X.

[0121] Referring to Figures 1 to 8, in some embodiments of this application, the fixing member 10 is provided with a first opening 16 through the second direction Y, and the floating member 20 has a plug-in terminal 24 and a wire harness 25 electrically connected to the plug-in terminal 24.

[0122] Specifically, the fixing member 10 includes a support plate 11, which has a first opening 16 extending through it in a direction perpendicular to its own surface. The floating member 20 includes a housing 21, one end of which has a plug-in terminal 24 passing through the first opening 16, facilitating connection of the plug-in terminal 24 to an external electrical component of the fixing member 10. An adapter 26 is also provided on the side of the housing 21 opposite to the plug-in terminal 24. The wiring harness 25 is plugged into the adapter 26 and electrically connected to the plug-in terminal 24 through the adapter 26, thereby achieving power conversion and signal conversion. Optionally, the wiring harness 25 can be fixedly connected to the adapter 26 via a clip 27.

[0123] In some embodiments of this application, the plug-in terminal 24 includes a signal plug-in component 241 and a power plug-in component 242. The signal plug-in component 241 is used for signal interaction, and the power plug-in component 242 is used for power transfer. The power plug-in component 242 includes a positive plug-in terminal 2421 and a negative plug-in terminal 2422, thereby transferring the positive and negative energy of the battery 100 to the power-consuming component. Optionally, the signal plug-in component 241 may include multiple plug-in holes, with the positive plug-in terminal 2421 and the negative plug-in terminal 2422 each including a plug-in hole.

[0124] The floating component 20 can be connected to the battery 100 via the wiring harness 25. The plug-in terminal 24 of the floating component 20 can be inserted through the first opening 16 and electrically connected to the power-consuming component, thereby realizing the power supply to the power-consuming component.

[0125] Referring to Figures 2 to 8, in some embodiments of this application, the fastener 10 includes a support portion 14, which is disposed at the edge of the first opening 16 and has a first surface 141.

The surface of the support portion 14 facing the floating member 20 along the second direction Y is the first surface 141.

[0127] By providing a support portion 14 at the edge of the first opening 16 and providing a first surface 141 facing the floating member 20 on the support portion 14, it is convenient to support the floating member 20 through the first surface 141 and to make the first surface 141 and the second surface 221 abut against each other through the wear-resistant layer 30.

[0128] Referring to Figures 2 to 8, in some embodiments of this application, the floating member 20 further includes a guide member 28. The guide member 28 and the plug-in terminal 24 are disposed on the same side of the floating member 20 and can pass through the first opening 16.
