Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a fast charging base fixing structure for electric vehicles and the electric vehicle itself. Background Technology

[0002] With the development of electric vehicle charging technology, fast charging technology has emerged. This technology is achieved through fast charging sockets and features short charging time. This, in turn, places higher demands on the stability and safety of charging equipment, especially requiring a reliable connection between the charging mechanism and the electric vehicle.

[0003] In related technologies, electric vehicle fast charging mechanisms are usually directly integrated with the electric vehicle's body shell, relying on the body shell itself to provide limited positioning support.

[0004] However, due to the material properties of the vehicle body shell itself, the above connection method still suffers from problems such as unstable fixing and susceptibility to vehicle vibration or external interference, which may affect the stability of the charging process. Utility Model Content

[0005] In view of the shortcomings of the existing production technology, the applicant provides a fast charging base fixing structure for electric vehicles and an electric vehicle, thereby making the connection between the fast charging base and the electric vehicle reliable and improving charging stability.

[0006] The technical solution adopted in this utility model is as follows: A fast charging base fixing structure for electric vehicles, comprising: First frame head tube; The second frame head tube is inclinedly disposed on top of the first frame head tube; A reinforcing component is disposed at the contact end between the first frame head tube and the second frame head tube; Fast charging mounting plate; and Fast charging dock; The reinforcing component includes a reinforcing sheet body, the reinforcing sheet body having a first mating portion adjacent to the first frame head tube and a second mating portion adjacent to the second frame head tube, and the reinforcing sheet body also having an extension portion extending in the horizontal direction; The extension is detachably connected to the fast charging mounting plate; The fast charging dock is detachably mounted on the fast charging mounting plate.

[0007] As a further improvement to the above technical solution: In one embodiment, the extension is connected to the fast charging mounting plate via a first fastener.

[0008] In one embodiment, the fast charging dock is mounted to the fast charging mounting plate by a second fastener.

[0009] In one embodiment, both the first and second frame head tubes are circular tubular structures.

[0010] In one embodiment, the shape of the first mating portion matches the arc surface of the first frame head tube.

[0011] In one embodiment, the shape of the second mating portion matches the arc surface of the second frame head tube.

[0012] In one embodiment, a cover is also included, which is hinged to the interface end of the fast charging dock.

[0013] In one embodiment, the reinforcing component is fixed to the contact ends of the first frame head tube and the second frame head tube by welding, and the reinforcing plate body, the first docking part, the second docking part and the extension part are integrally formed into an integrated structure.

[0014] In one embodiment, the fast charging mounting plate is a metal sheet.

[0015] On the other hand, this application provides an electric vehicle, including the above-described fast charging base fixing structure for an electric vehicle.

[0016] The beneficial effects of this utility model are as follows: This utility model has a compact structure. By adding a reinforcing component at the junction of the first and second frame head tubes, the mounting base of the fast charging socket is transferred from the traditional, relatively weak vehicle body shell to the main frame structure of the electric vehicle. The reinforcing component itself, as a structural reinforcement, directly compensates for the local weak points at the connection of the frame tubes, forming a high-rigidity support node. In addition, the horizontally extending part on the reinforcing component creates a flat area for installation. The fast charging mounting plate is fixed to this extension by fasteners, thereby achieving a connection stability far exceeding that of direct installation on the vehicle body shell, effectively resisting vibrations and impacts from multiple directions during vehicle operation.

[0017] This utility model also has the following advantages: This utility model's fast charging base and the static or dynamic loads that may be subjected to during charging are directly transferred to the reinforcing component through the fast charging mounting plate and extension, and then distributed to the entire frame main structure through its two joints that respectively fit the frame head tube. By utilizing the high strength characteristics of the frame itself, the load is efficiently distributed, avoiding loosening of the mounting point or deformation of the shell caused by stress concentration.

[0018] The fast charging base and the fast charging mounting plate, as well as the fast charging mounting plate and the extension of the reinforcing component, are all connected by a detachable fastening mechanism. This modular design allows the fast charging base or mounting plate to be repaired or replaced independently without modifying the main body of the vehicle frame or the reinforcing component, which greatly simplifies the after-sales maintenance process and reduces maintenance costs.

[0019] The interface end of this utility model fast charging dock is provided with a hinged cover, which can effectively prevent dust, rainwater and other foreign objects from entering the charging interface, thereby improving the safety of the charging process and the service life of the interface.

[0028] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.

[0029] like Figures 1-2 The accompanying drawing shows a structural diagram of a fast charging base fixing structure for electric vehicles according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0030] This application provides a fast charging base fixing structure for electric vehicles. The main supporting part of the structure is the frame of the electric vehicle, specifically the front area of ​​the frame.

[0031] In some embodiments, the frame includes a first head tube 1 and a second head tube 3; Specifically, the first frame head tube 1 is usually set vertically or nearly vertically, forming the core support tube at the front of the frame. The second frame head tube 3 extends backward and upward from the top of the first frame head tube 1, forming a triangular area at the front of the frame together with the first frame head tube 1. The two form a contact end at the intersection.

[0032] In a preferred embodiment, the first frame head tube 1 and the second frame head tube 3 are preferably tubular structures in the shape of round tubes to accommodate common frame designs.

[0033] Understandably, in order to solve the problem of insufficient local strength at the connection of the frame tubes and to provide a high-rigidity fast charging base, a reinforcing component 2 is fixedly installed at the contact end of the first frame head tube 1 and the second frame head tube 3.

[0034] In some embodiments, the reinforcing component 2 includes a reinforcing sheet body 201, which is preferably made of a high-strength metal sheet by stamping or casting; the outline of the reinforcing sheet body 201 is configured to fit simultaneously with the first frame head tube 1 and the second frame head tube 3.

[0035] Specifically, the reinforcing plate body 201 has a first mating portion 202 on the side facing the first frame head tube 1, the concave arc shape of which matches the outer arc surface of the first frame head tube 1; the reinforcing plate body 201 has a second mating portion 203 on the side facing the second frame head tube 3, the concave arc shape of which matches the outer arc surface of the second frame head tube 3. By tightly fitting the first mating portion 202 and the second mating portion 203 onto the two frame head tubes respectively, the reinforcing component 2 can effectively enhance the structural rigidity and strength of the connection node.

[0036] Furthermore, the reinforcing plate body 201 extends integrally in the horizontal direction (typically pointing to the side of the vehicle) to form an extension 204, which, understandably, provides a flat and stable mounting platform.

[0037] Furthermore, the reinforcing body 201, the first docking part 202, the second docking part 203, and the extension part 204 together form an integrated structure.

[0038] A fast charging mounting plate 4 is detachably mounted on the extension 204. The fast charging mounting plate 4 is preferably a metal plate with mounting holes.

[0039] Correspondingly, corresponding connection holes are also provided on the extension 204 of the reinforcing plate body 201. The fast charging mounting plate 4 is securely locked onto the extension 204 by a first fastener 5 (e.g., bolt, screw, etc.) passing through these connection holes. This detachable connection facilitates subsequent maintenance and replacement.

[0040] A fast charging socket 6 is further detachably mounted on the fast charging mounting plate 4. The fast charging socket 6 is the main body of the fast charging interface for the electric vehicle. The base of the fast charging socket 6 is usually provided with mounting holes. After aligning with the preset mounting holes on the fast charging mounting plate 4, it is fixed with a second fastener 7 (which can also be a bolt, screw, etc.), thereby firmly mounting the fast charging socket 6 on the fast charging mounting plate 4.

[0041] To protect the charging port of the fast charging dock 6 from dust and water, a cover 8 is hinged to the port end of the fast charging dock 6. The cover 8 can be flipped around the hinge axis like a lid to cover the charging port when not charging, preventing dust, rain and other foreign objects from entering; when charging is needed, it can be easily lifted.

[0042] This utility model also provides an electric vehicle, which includes the fast charging base fixing structure for electric vehicles described in any of the above embodiments. The fast charging base fixing structure is usually installed on the front side of the electric vehicle frame, so that the fast charging base 6 can be easily connected.

[0043] In practical applications, the working principle of this utility model is as follows: This utility model transfers the mounting base of the fast charging socket 6 from the traditional body panel (such as a plastic shell) to the main frame structure. By adding a reinforcing component 2 that matches and fits with the first frame head tube 1 and the second frame head tube 3, the local rigidity at the mounting point is significantly enhanced. The loads borne by the fast charging base 6, including its own weight, cable insertion and extraction force, and vibration and impact during vehicle operation, are transmitted through the following path: fast charging base 6 → second fastener 7 → fast charging mounting plate 4 → first fastener 5 → extension 204 of reinforcing plate body 201 → reinforcing plate body 201 → distributed to the first frame head tube 1 and the second frame head tube 3 via the first docking part 202 and the second docking part 203 → borne by the entire robust frame system.

[0044] Therefore, this utility model effectively avoids the problems of shaking, abnormal noise and loose connection caused by weak mounting base, greatly improves the reliability and stability of fast charging connection, and the modular detachable design also facilitates maintenance.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
