In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0039] It should be noted that in the description of the present invention, the terms "connection" and "installation" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through an intermediate medium; it can be a mechanical connection or an electrical connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] When the existing support frame rebounds, it will collide with the fixing part through surface contact, generating a large collision noise, which reduces the user's experience.

[0041] Based on this, one embodiment of the utility model provides a noise reduction support device, referring to Figures 1 to 4 , the device comprises a fixing member 1 and a support frame 2 rotatably mounted on the fixing member 1;

[0042] The support frame 2 has a vertically arranged propped-up state and a horizontally arranged folded state; the support frame 2 includes a limiting portion 21, and when the support frame 2 is in the folded state, the limiting portion 21 and the fixing member 1 are in line contact or point contact.

[0043] Compared with the prior art, the support device provided in the present application horizontally limits the support frame 2 by making the fixing member 1 and the limiting portion 21 in line contact or point contact. Since the contact area between the fixing member 1 and the limiting portion 21 in the folded state is reduced, the collision noise generated by the support frame 2 during rebound can be reduced, thereby improving the user experience.

[0044] Furthermore, the fixing member 1 is a plate structure, on which a plurality of mounting through holes are provided, and the support device is fixed to the frame of the electric vehicle through the mounting through holes. The outline of the fixing member 1 and the number and position of the mounting through holes on the fixing member 1 can be reasonably set according to the actual shape of the electric vehicle, so that the support device can adapt to various types of electric vehicles. The above-mentioned support device has strong versatility and is easy to install and use; and the fixing member 1 adopts a plate structure, which has the advantages of simple shape, simple production process and small space occupation, meeting the needs of mass production.

[0045] In this embodiment, the fixing member 1 is provided with a first abutting surface 11 and a second abutting surface 12, wherein:

[0046] When the support frame 2 is in the propped-up state, the limiting portion 21 is in surface contact with the first abutting surface 11;

[0047] When the support frame 2 is in the folded state, the limiting portion 21 and the second abutting surface 12 are in line contact.

[0048] Reference Figure 2 The support frame 2 and the fixing member 1 adopt a surface contact limiting form during the parking process, which can improve the stability of the support frame 2 during the parking process and avoid the electric vehicle from being unstable after a long period of parking. Figure 3 and Figure 4 The support frame 2 adopts a line contact limiting form with the fixing member 1 during rebound, which can reduce the contact area between the fixing member 1 and the limiting portion 21 during rebound, thereby reducing the collision noise generated by the support frame 2 during rebound.

[0049] Continue to refer to Figure 3 and Figure 4 The limiting portion 21 includes two spaced-apart mounting plates, and the limiting portion 21 is connected between the two mounting plates; the two mounting plates and the limiting portion 21 form a U-shaped groove 22, and the fixing member 1 is inserted into the U-shaped groove 22;

[0050] When the support frame 2 is in the folded state, the bottom surface of the U-shaped groove 22 is in line contact with the second abutting surface 12 on the fixing member 1 .

[0051] Specifically, when the support frame 2 is in the folded state, the bottom surface of the U-shaped groove 22 and the second abutting surface 12 on the fixing member 1 are arranged at an angle, and one end of the bottom surface of the U-shaped groove 22 abuts against the second abutting surface 12 .

[0052] Continue to refer to Figure 4A rubber strip 24 is provided at the bottom of the U-shaped groove 22. When the support frame 2 is in the folded state, the rubber strip 24 is located between the second abutting surface 12 and the limiting portion 21. The rubber strip 24 plays a buffering role in the process of the limiting portion 21 contacting the second abutting surface 12, which can further reduce the collision noise generated by the support frame 2 during rebound, and reduce the collision strength between the support frame 2 and the second abutting surface 12, thereby avoiding damage to the second abutting surface 12 and the support frame 2 due to long-term collision, and improving the service life of the support device.

[0053] On the basis of the above structure, a rubber strip installation hole 25 is provided on the limiting portion 21, and part of the rubber strip 24 is provided in the rubber strip installation hole 25. In this embodiment, the cross section of the rubber strip 24 is a circular structure; the rubber strip installation hole 25 passes through the two mounting plates and the limiting portion 21, and the cross-sectional profile of the part of the rubber strip installation hole 25 located in the U-shaped groove 22 is a partial circular structure; the rubber strip 24 is pressed into the rubber strip installation hole 25 through an interference fit, and part of the rubber strip 24 located in the U-shaped groove 22 protrudes from the outside of the rubber strip installation hole 25 in the direction close to the fixing member 1.

[0054] When the rubber strip 24 is damaged, the user only needs to push the damaged rubber strip 24 out of the rubber strip installation hole 25 when the support frame 2 is in the propped-up state, and press in a new rubber strip 24 to complete the replacement of the rubber strip 24 without disassembling the supporting device, thereby facilitating the replacement of the rubber strip 24.

[0055] Reference Figure 5 and Figure 6 A plurality of ball plungers 3 are arranged between the fixing member 1 and one or any one of the mounting plates.

[0056] Specifically, each ball plunger 3 is inserted into the fixing member 1, and a first limiting groove for inserting the telescopic end of the ball plunger 3 is provided on one or any one of the mounting plates;

[0057] Alternatively, each ball plunger 3 is inserted into one of the mounting plates, and the fixing member 1 is provided with a second limiting groove 14 for inserting the telescopic end of the ball plunger 3 .

[0058] In this embodiment, two ball plungers 3 are provided on each mounting plate, and correspondingly, two second limiting grooves 14 are provided on the front and rear end surfaces of the fixing member 1, and the two second limiting grooves 14 on the front and rear end surfaces of the fixing member 1 are evenly distributed around the rotation axis of the support frame 2. The plurality of ball plungers 3 correspond to the plurality of second limiting grooves 14 one by one, and when the support frame 2 is in the propped-up state, the telescopic end of the ball plunger 3 is inserted into the corresponding second limiting groove 14.

[0059] The support frame 2 can be vertically limited by the ball plunger 3 and the second limiting groove 14, so that the support frame 2 is in a relatively stable folded state, the phenomenon of random rebound of the support frame 2 is alleviated, and it is convenient for users to use.

[0060] In the above structure, the ball plunger 3 can be assembled by screw connection or press-in, which has the advantages of low cost, convenient assembly and disassembly, and easy replacement. The ball plunger 3 is a standard part and can be replaced by the user.

[0061] Reference Figure 7 and Figure 8 , the noise reduction support device also includes a torsion spring 4, which is mounted on the fixing member 1;

[0062] The torsion spring 4 includes a torsion spring body, a first connecting rod and a second connecting rod; the first connecting rod and the second connecting rod are respectively connected to two ends of the torsion spring body, and are respectively connected to the fixing member 1 and the support frame 2.

[0063] In this embodiment, the noise reduction support device further includes a torsion spring installation shaft 5, which is installed on the fixing member 1, and the torsion spring body is sleeved on the torsion spring installation shaft 5; the fixing member 1 is provided with a first fixed shaft 13, and the support frame is provided with a second fixed shaft 23; one end of the first connecting rod is fixedly connected to the torsion spring body, and the other end thereof is hooked on the first fixed shaft 13; one end of the second connecting rod is fixedly connected to the torsion spring body, and the other end thereof is hooked on the second fixed shaft 23. The installation of the torsion spring 4 is achieved through the above structure.

[0064] Existing support devices usually use a tension spring to pull the support frame 2 to rebound. During installation, the two ends of the tension spring are hooked on the fixing member 1 and the support frame 2 respectively. Since only the two ends of the tension spring are limited, the tension spring is easy to fall from the fixing member 1 and / or the support frame 2, affecting the normal use of the device. The present application uses a torsion spring 4 to pull the support frame 2 to rebound. The torsion spring installation shaft 5 can limit the middle position of the torsion spring to prevent the torsion spring 4 from falling, thereby improving the stability of the overall structure of the device.

[0065] Continue to refer to Figure 7 The noise reduction support device further includes a rotating shaft 6, and the support frame 2 is rotatably mounted on the fixing member 1 via the rotating shaft 6. Specifically, the rotating shaft 6 sequentially passes through one of the mounting plates, the fixing member 1 and the other mounting plate, and both ends of the rotating shaft 6 are limited by fasteners or shaft shoulders, so that the support frame 2 is rotatably mounted on the fixing member 1.

[0066] Another aspect of the present invention provides an electric vehicle, which includes the noise reduction support device described in any of the above embodiments. Therefore, the electric vehicle at least has the technical effects of the above noise reduction support device, which will not be repeated here.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
