[0043] See also Figures 1 to 6 This embodiment provides a fixing structure for fixing a low-voltage plug-in of a new energy vehicle, including:

[0044] The supporting part 10 includes: a first elastic unit 14, a supporting body 11 and a clamping member 12; the surface of the supporting body 11 supporting the object 40 to be supported is a supporting surface 111, and the supporting surface 111 is adapted to the object 40 to be supported, one end of the clamping member 12 is connected to the supporting body 11, and the other end of the clamping member 12 is against the object 40 to be supported, and the clamping member 12 is used to fix the object 40 to be supported on the supporting surface 111; the first elastic unit 14 is placed on the supporting body 11, and the first elastic unit 14 is used to apply elastic force to the low-pressure plug-in

[0045] A support portion 20 , wherein the support portion 20 is connected to the supporting body 11 and is disposed on a side of the supporting body 11 away from the supporting surface 111 , and the support portion 20 is used to support the supporting portion 10 ;

[0046] The fixing portion 30 is connected to the supporting body 11 , and the fixing portion 30 is disposed on a side of the supporting body 11 away from the supporting surface 111 , and the fixing portion 30 is used to fix the supporting body 10 on the base 50 .

[0047] First, it should be noted that the object to be supported 40 is a low-voltage plug-in. The base 50 is a vehicle body frame, a battery tray, etc.

[0048] The supporting portion 10 includes: the supporting body 11, the clamping member 12 and the first elastic unit 14;

[0049] The supporting body 11 is made of high-strength, lightweight material (such as aluminum alloy), and the top of the supporting body 11 is the supporting surface 111, which is a flat plane, or a groove that matches the shape of the bottom of the low-pressure plug-in. Of course, in other implementations, the supporting surface 111 may be provided with an anti-slip texture or a soft material layer (such as a rubber pad) to increase the friction between the supporting body 11 and the low-pressure plug-in and prevent the low-pressure plug-in from sliding during operation.

[0050] One end of the clamping member 12 is fixed to the two side edges of the supporting body 11 by screws, rivets or integral molding, and the other end of the clamping member 12 is a hook-shaped structure bent toward the supporting surface 111. The clamping member 12 is used to hook the plane, protrusion and / or hole on the edge of the low-voltage plug-in to achieve a stable clamping fixation.

[0051] The first elastic unit 14 is placed on the supporting surface 111. When the low-pressure plug-in is placed on the supporting surface 111, the first elastic unit 14 applies a moderate elastic force to the low-pressure plug-in to ensure that the low-pressure plug-in fits tightly with the supporting surface 111 while absorbing vibration and impact.

[0052] The base 50 is stepped. When the supporting portion 10 is placed on the base 50, one side of the supporting portion 10 is suspended to reduce the contact area between the supporting portion 10 and the base 50, thereby reducing vibration and impact. The supporting portion 20 is placed on the side of the supporting body 11 away from the supporting surface 111, and is located below the suspended part of the supporting portion 10. The side of the supporting portion 20 away from the supporting portion 10 abuts against the base 50. And the side of the supporting portion 20 away from the fixing portion 30 is elastic to absorb vibration and impact.

[0053] The fixing portion 30 is placed at an appropriate position on the back side of the supporting body 11 (i.e., the opposite side of the supporting surface 111 ), and is connected to the base 50 (such as a battery tray) by a detachable method such as threading or snapping, so that the supporting portion 10 and the supporting portion 20 are fixed on the base 50 .

[0054] The integrated configuration enables the supporting portion 10, the support portion 20 and the fixing portion 30 to be integrally formed through a precision mold, thereby ensuring a compact structure without gaps, thereby improving overall durability and reliability.

[0055] When the low-voltage plug-in is placed on the supporting surface 111 of the supporting portion 10, the supporting surface 111 provides a stable support base for the low-voltage plug-in. The clamping member 12 fixes the low-voltage plug-in to achieve a stable clamping fixation. At the same time, the first elastic unit 14 placed on the supporting surface 111 will apply a moderate elastic force to the low-voltage plug-in to ensure that the low-voltage plug-in fits tightly with the supporting surface 111. The first elastic unit 14 also helps to absorb vibration and impact from the vehicle during driving, protecting the low-voltage plug-in and its connecting lines from damage.

[0056] When the supporting portion 10 is placed on the base 50, one side of the supporting portion 10 is suspended. This reduces the contact area between the supporting portion 10 and the base 50, which helps to further reduce the impact of vibration and impact on the low-pressure plug-in. The supporting portion 20 not only provides additional support for the supporting portion 10, but also further absorbs and disperses vibration and impact energy through its elastic design away from the side of the fixing portion 30 (such as using elastic materials or designing an elastic structure). This shock absorption effect helps to maintain the stability of the low-pressure plug-in under complex working conditions.

[0057] Different from the prior art, the above technical solution realizes effective fixation and protection of the low-voltage plug-in of the new energy vehicle through the arrangement of the first elastic unit 14, the supporting body 11 and the clamping member 12. This design not only improves the stability and safety of the low-voltage plug-in during vehicle driving, but also helps to extend its service life and reduce maintenance costs.

[0058] According to some embodiments of the present application, referring to Figure 1 and Figure 3 The first elastic unit 14 is a strip elastic sheet, a supporting through hole 13 is penetrated through the supporting body 11, and the strip elastic sheet is placed in the supporting through hole 13; one end of the first elastic unit is connected to a part of the inner wall of the supporting through hole 13; the first elastic unit also protrudes from the supporting surface 111 of the supporting body 11.

[0059] The first elastic unit 14 is an elastic sheet, and the material of the elastic sheet is consistent with the material of the supporting body 11; the supporting through hole 13 passes through the supporting body 11, and part of the inner wall of the supporting through hole 13 is connected to one end of the first elastic unit 14, and the other end of the first elastic unit 14 extends out of the supporting through hole 13 and protrudes from the supporting surface 111. Further, when the object to be carried is placed on the supporting portion 10, the object to be carried first contacts with the end of the first elastic unit 14 away from the supporting portion 10; at this time, the first elastic unit 14 is bent by force and stores elastic potential energy, so that the first elastic unit 14 applies an upward elastic force to the object to be carried.

[0060] According to some embodiments of the present application, referring to Figure 1 , Figure 5 as well as Figure 6 The clamping member 12 includes: a lifting unit 121 and an extension unit 122, one end of the lifting unit 121 is connected to the supporting body 11, and the other end is connected to the extension unit 122; the extension unit 122 is placed above the supporting surface 111, and the lifting unit 121 is placed on the edge of the supporting surface 111;

[0061] When the object 40 to be supported is placed on the supporting surface 111 , the side of the extension unit 122 opposite to the supporting surface 111 abuts against the object 40 to be supported.

[0062] The lifting unit 121 is a vertically arranged side plate, one side of the lifting unit 121 is firmly connected to the edge of the supporting body 11, and the other side is connected to the extension unit 122. The extension unit 122 is a flat or slightly curved component to ensure that it can accurately abut against the side or top of the low-pressure plug-in; in some embodiments, the side of the extension unit 122 away from the supporting surface 111 has a chamfered angle so that the low-pressure plug-in can be quickly installed. Specifically, during installation, the low-pressure plug-in falls from above the supporting surface 111, contacts the chamfered angle of the extension unit 122, and continues to fall; at this time, the lifting unit 121 bends outward, and when the low-pressure plug-in is placed on the supporting surface 111, the lifting unit 121 is reset (i.e., in a vertical state); when the low-pressure plug-in is placed on the supporting surface 111, the extension unit 122 abuts against the top of the low-pressure plug-in, increasing the stability and safety of the fixation.

[0063] According to some embodiments of the present application, referring to Figures 1 to 6 There are two clamping members 12, and the two clamping members 12 are arranged oppositely on both sides of the supporting surface 111 to effectively fix the low-voltage plug-in. Of course, in some embodiments, a plurality of clamping members 12 are arranged around the low-voltage plug-in.

[0064] According to some embodiments of the present application, referring to Figure 1 , Figure 2 , Figure 4 as well as Figure 5 The fixing portion 30 includes: a support unit 31 and a protrusion 32, the support unit 31 is connected to the supporting portion 10, the support unit 31 extends in a direction away from the supporting portion 10, the protrusion 32 is placed on the support unit 31, and the base 50 has a fixing hole 51 adapted to the protrusion 32, the protrusion 32 is placed in the fixing hole 51, and the protrusion 32 is used to fix the supporting portion 10 to the base 50.

[0065] The fixing portion 30 includes a support unit 31 and a projection 32. The support unit 31 is a solid component, and the support unit 31 extends from the back side of the supporting portion 10 in a direction away from the supporting surface 111 to form a stable connection point with the base 50; in some embodiments, the support unit 31 is close to the side wall of the base 50 to further improve the stability of the supporting portion 10. The projection 32 is fixed to the support unit 31, and the projection 32 matches the fixing hole 51 on the base 50 (such as cylindrical, square, etc.) so as to be inserted and fixed in the fixing hole 51. The projection 32 also includes a thread, a barb or other locking mechanism to enhance the connection strength with the fixing hole 51. Furthermore, the base 50 is pre-set with a fixing hole 51 that matches the projection 32.

[0066] According to some embodiments of the present application, referring to Figure 4 The support portion 20 includes: a support body 21 and a second elastic unit 22. The support body 21 is connected to the supporting body 11. The second elastic unit 22 is an elastic strip. The elastic strip is bent and both ends of the elastic strip are connected to the support body 21. Part of the elastic strip protrudes from the support body 21 away from the surface of the supporting portion 10.

[0067] The support portion 20 includes: the support body 21 and the second elastic unit 22 (i.e., elastic strip). The support body 21 is the main support structure and is firmly connected to the supporting body 11. The second elastic unit 22 is bent and fixed on both sides of the support body 21 or on one end of the support body 21 away from the supporting portion 10. Part of the second elastic unit 22 protrudes from the surface of the support body 21 away from the supporting portion 10, forming a shock-absorbing structure similar to a spring.

[0068] The second elastic unit 22 is made of a material with high elasticity, fatigue resistance and good recovery (such as stainless spring steel, rubber, etc.). The bending degree and number of the elastic strips can be adjusted according to the weight, size and required shock absorption effect of the low-pressure plug-in.

[0069] When the low-pressure plug-in is placed on the supporting portion 10, the first elastic unit 14 first provides a preliminary elastic force to make the low-pressure plug-in fit tightly against the supporting surface 111. At the same time, the elastic strip of the support portion 20 also begins to play a role. During the driving of the vehicle, due to uneven road conditions or vehicle vibrations, the low-pressure plug-in may be subjected to impact and vibration from all directions. At this time, the elastic strip can absorb and disperse the impact energy, reducing their direct impact on the plug-in and the supporting portion 10. This shock-absorbing effect not only protects the low-pressure plug-in from damage, but also improves the stability and durability of the entire fixed structure.

[0070] According to some embodiments of the present application, referring to Figure 2 and Figure 6 , and also includes: a limiting portion 15, which is connected to the supporting body 11, and the limiting portion 15 is placed on the side of the supporting body 11 away from the supporting surface 111, and the limiting portion 15 is adapted to the limiting hole 52 on the base 50, and the limiting portion 15 is used to prevent the supporting portion 10 from moving on the base 50.

[0071] The limiting portion 15 is connected to the supporting body 11 and is placed on a side of the supporting body 11 away from the supporting surface 111. The limiting portion 15 matches the limiting hole 52 on the base 50, and the limiting portion 15 can be a pin, a protrusion, or a structure of other shapes. When the supporting part 10 is fixed on the base 50, the limiting portion 15 will be inserted into the limiting hole 52 to form an additional fixing point, effectively preventing the supporting part 10 from moving horizontally on the base 50.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
