Description

Technical Field

[0001] This utility model belongs to the technical field of electric motorcycles, specifically relating to a horn damping installation structure. Background Technology

[0002] In electric motorcycles, the horn is typically mounted below the seat tube or near the front fork to facilitate connection to the handlebar button wiring and ensure sound propagation forward. The controller is usually installed inside the frame or under the seat for motor control and signal processing. However, some models place the controller below the seat tube for wiring convenience, resulting in its proximity to the horn. With the development of intelligent electric motorcycles, more and more electric motorcycles are adopting integrated controllers, which integrate an inertial measurement unit containing a gyroscope to achieve functions such as TCS traction control, hill start assist, and tilt anti-theft. However, currently, the horn is generally fixed directly to the frame with a rigid bracket, lacking effective vibration damping design. The electromagnetic vibration generated by the horn is transmitted to the frame through the bracket and then to the controller. When the horn vibrates at high frequencies, it can easily affect the attitude detection accuracy of the gyroscope, thus reducing the stability of the entire vehicle's electronic control system. Although some models have attempted to add rubber pads between the bracket and the horn for cushioning, the vibration damping effect is poor.

[0003] Therefore, there is an urgent need for a horn damping mounting structure with a reasonable structure and good vibration reduction effect. Under the premise of ensuring normal sound production and reliable installation of the horn, it can effectively isolate its working vibration and prevent interference to the nearby controller and internal gyroscope, so as to improve the reliability and safety of the vehicle's electronic system. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a horn vibration damping mounting structure, which solves the technical problem that the working vibration of the horn can easily interfere with the adjacent controller, thereby improving the reliability and safety of the vehicle's electronic system.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A horn damping mounting structure includes a frame, an elastic pad, a horn, a first bolt, a second bolt, and a nut. The first bolt passes through the elastic pad and connects to the frame. The elastic pad includes opposing inner and outer surfaces, which abut against the frame and the head of the first bolt, respectively. The horn includes a sound-emitting body and a connecting plate. One end of the connecting plate is located on the outer surface, and the other end of the connecting plate is connected to the sound-emitting body. The sound-emitting body is spaced from the frame. The second bolt passes through the connecting plate and the elastic pad and connects to the nut. The connecting plate abuts against the head and outer surface of the second bolt, and the nut abuts against the inner surface. A recessed clearance portion is formed on the frame and / or the inner surface. The tail of the second bolt and the nut are located in the clearance portion and are spaced from the inner wall of the clearance portion.

[0006] Furthermore, the horn damping mounting structure also includes a base, which is connected to the vehicle frame. The side of the base away from the vehicle frame is a flat surface and abuts against the inner side in place of the vehicle frame. A clearance hole is provided through the base, which is directly opposite the clearance part.

[0007] Furthermore, there are two first bolts, and the connecting plate is located between the two first bolts.

[0008] Furthermore, the outer surface includes a first abutting surface and a second abutting surface. The thickness of the elastic pad at the first abutting surface is greater than the thickness at the second abutting surface. A stepped surface is formed between the first abutting surface and the second abutting surface. There are two first abutting surfaces, which abut against the heads of the two first bolts respectively. The second abutting surface and the stepped surface abut against the connecting plate respectively.

[0009] Furthermore, the other end of the connecting plate extends outward and is connected to the sound-generating body.

[0010] Furthermore, the elastic pad is V-shaped with its tip pointing away from the sound-generating body, the second bolt is located at the tip of the V-shape, and the two first bolts are located at the two arms of the V-shape respectively.

[0011] Furthermore, the elastic pad has a first through hole corresponding to the first bolt, and the inner side has a first countersunk hole corresponding to the first through hole. A first shoulder bushing is provided in the first through hole, and the shoulder of the first shoulder bushing is located in the first countersunk hole. The head of the first bolt abuts against the first shoulder bushing, and the shoulder of the first shoulder bushing abuts against the elastic pad and the frame respectively.

[0012] Furthermore, the elastic pad has a second through hole corresponding to the second bolt, and the inner side has a second countersunk hole corresponding to the second through hole. The second countersunk hole forms a relief portion on the inner side. A second shoulder bushing is provided in the second through hole. The shoulder of the second shoulder bushing is located in the second countersunk hole. The connecting plate abuts against the head of the second bolt and the second shoulder bushing respectively. The shoulder of the second shoulder bushing abuts against the elastic pad and the nut respectively.

[0013] Furthermore, the horn damping mounting structure also includes a controller. The frame includes a riser and a beam tube. The upper end of the beam tube is connected to the riser, and the lower end extends backward at an angle. The horn and the controller are both connected to the beam tube, with the horn located above the controller and close to the riser.

[0014] Furthermore, the connecting plate is centered in the width direction of the frame, and the other end of the connecting plate extends downward along the beam tube. Two first bolts are symmetrically distributed on both sides of the connecting plate along the width direction of the frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the horn vibration damping mounting structure described in this utility model, the elastic rubber pad is partially pressed and fixed to the vehicle frame by the first bolt, and the horn connecting plate is fixed to the elastic rubber pad by the second bolt and nut. This allows the horn to be indirectly connected to the vehicle frame through the elastic rubber pad, which is different from simply placing a rubber pad between the horn and the vehicle frame. When the horn vibrates during operation, the elastic rubber pad can not only undergo compression and stretching deformation in the thickness direction to provide bidirectional buffering, but also achieve multi-directional free deformation in the lateral and rotational directions with the help of the clearance part, thus achieving multi-directional vibration damping. This floating mounting method can effectively isolate the electromagnetic vibration of the horn from being transmitted to the vehicle frame while ensuring normal sound production and reliable installation. This prevents vibration from interfering with the gyroscope in the adjacent controller, which is beneficial to improving the reliability and safety of the vehicle's electronic system.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0018] Example: Please see Figure 3 and Figure 4A horn damping mounting structure includes a frame 1, an elastic pad 2, a horn 3, a first bolt 4, a second bolt 5, and a nut 6. The first bolt 4 passes through the elastic pad 2 and connects to the frame 1. The elastic pad 2 includes opposing inner and outer surfaces, which abut against the frame 1 and the head of the first bolt 4, respectively. The horn 3 includes a sound-emitting body 7 and a connecting plate 8. One end of the connecting plate 8 is located on the outer surface, and the other end of the connecting plate 8 is connected to the sound-emitting body 7. The sound-emitting body 7 is spaced from the frame 1. The second bolt 5 passes through the connecting plate 8 and the elastic pad 2 and connects to the nut 6. The connecting plate 8 abuts against the head and outer surface of the second bolt 5, and the nut 6 abuts against the inner surface. A relief portion 9 is recessed on the frame 1 and / or the inner surface. The tail of the second bolt 5 and the nut 6 are located in the relief portion 9 and are spaced from the inner wall of the relief portion 9.

[0019] In the horn vibration damping mounting structure described in this utility model, the first bolt 4 passes through the elastic rubber pad 2 and connects to the frame 1, partially pressing and fixing the elastic rubber pad 2. The second bolt 5 passes through the connecting plate 8 and the elastic rubber pad 2 and connects to the nut 6, fixing the connecting plate 8 of the horn 3 onto the elastic rubber pad 2. This allows the horn 3 to be indirectly connected to the frame 1 through the elastic rubber pad 2, rather than a rigid connection, unlike directly placing a rubber pad between the horn 3 and the frame 1. The clearance part 9 provides space for the tail of the second bolt 5 and the nut 6, preventing them from directly contacting the frame 1. When the horn 3 vibrates during operation, the elastic rubber pad 2 can not only undergo compression and stretching deformation in the thickness direction, providing bidirectional buffering, but also, due to the presence of the clearance part 9, the elastic rubber pad 2 can freely deform in other directions (such as laterally or rotationally), achieving multi-directional vibration damping. This floating mounting method can effectively isolate the electromagnetic vibration of the horn 3 from being transmitted to the frame 1 while ensuring the normal sound production and reliable installation of the horn 3, thereby preventing vibration interference to the gyroscope in the adjacent controller 17, which is beneficial to improving the reliability and safety of the vehicle's electronic system.

[0020] Please see Figure 2 , Figure 3 and Figure 4 The horn damping mounting structure also includes a base 10, which is connected to the frame 1. The side of the base 10 away from the frame 1 is flat and abuts against the inner side of the frame 1. The base 10 has a through hole 11 that is directly opposite to the relief part 9. In this way, even if the surface of the frame 1 is uneven, the base 10 can provide a flat mounting position for the elastic pad 2 and the horn 3, ensuring that the elastic pad 2 is evenly stressed, which is beneficial to improving the installation reliability and damping effect. The relief hole 11 on the base 10 is directly opposite to the relief part 9, ensuring that the second bolt 5 and nut 6 have enough space and do not affect the deformation of the elastic pad 2. In this embodiment, the base 10 is plate-shaped and welded to the frame 1.

[0021] Please see Figure 1 , Figure 2 and Figure 3 There are two first bolts 4, and the connecting plate 8 is located between the two first bolts 4; in this way, the elastic pad 2 is pressed and fixed by the two first bolts 4, which forms a constraint on the central area where the connecting plate 8 is located, preventing the elastic pad 2 from undergoing excessive lateral displacement or torsion during vibration, and ensuring the stability of the horn 3's installation position on the frame 1; at the same time, the symmetrical layout of the two first bolts 4 helps to balance the force, which is beneficial to improving the reliability of the shock absorption structure.

[0022] Please see Figure 4 The outer surface includes a first abutting surface 12 and a second abutting surface 13. The thickness of the elastic pad 2 at the first abutting surface 12 is greater than the thickness at the second abutting surface 13. A stepped surface 14 is formed between the first abutting surface 12 and the second abutting surface 13. There are two first abutting surfaces 12, which abut against the heads of the two first bolts 4 respectively. The second abutting surface 13 and the stepped surface 14 abut against the connecting plate 8 respectively. In this way, when the horn 3 is working, the stepped surface 14 can restrict the connecting plate 8 from rotating around the second bolt 5, preventing the horn 3 from twisting. At the same time, the stepped surface 14 structure provides buffering in the circumferential direction, absorbs part of the rotational energy, further enhances the shock absorption effect, and ensures the stability of the horn 3.

[0023] Please see Figure 2 and Figure 3 The other end of the connecting plate 8 extends outward and connects to the sound-generating body 7. In this way, the connecting plate 8 extends outward and connects to the sound-generating body 7. On the one hand, the position of the sound-generating body 7 can be staggered from the first bolt 4 and the second bolt 5, which can avoid installation interference and facilitate operation. On the other hand, the extended connecting plate 8 can also play a certain role in buffering and absorbing energy, which is beneficial to improving the shock absorption effect in conjunction with the elastic rubber pad 2.

[0024] Please see Figure 2 and Figure 3 The elastic pad 2 is V-shaped with its tip pointing away from the sound source 7. The second bolt 5 is located at the tip of the V-shape, and the two first bolts 4 are located at the two arms of the V-shape respectively. In this way, the V-shaped design increases the material length of the elastic pad 2 between the second bolt 5 and each first bolt 4, thereby providing a longer deformation path. When the speaker 3 vibrates, the elastic pad 2 can absorb vibration energy through greater deformation, significantly improving the damping effect, especially in terms of low-frequency vibration isolation.

[0025] Please see Figure 4The elastic pad 2 has a first through hole corresponding to the first bolt 4, and a first countersunk hole corresponding to the first through hole on its inner side. A first shoulder bushing 15 is provided in the first through hole, and the shoulder of the first shoulder bushing 15 is located in the first countersunk hole. The head of the first bolt 4 abuts against the first shoulder bushing 15, and the shoulder of the first shoulder bushing 15 abuts against the elastic pad 2 and the frame 1 respectively. In this way, the length of the shoulder bushing corresponds to the total length of the first through hole and the first countersunk hole. When the first bolt 4 is tightened, the bolt head abuts against the first shoulder bushing 15, and the shoulder of the first shoulder bushing 15 contacts the frame 1, thereby limiting the screw-in depth of the bolt, preventing the elastic pad 2 from being over-compressed or even broken, and ensuring that the elastic pad 2 maintains an appropriate pre-compression state, thereby maintaining its shock absorption performance.

[0026] Please see Figure 4 The elastic pad 2 has a second through hole corresponding to the second bolt 5, and a second countersunk hole corresponding to the second through hole on its inner side. The second countersunk hole forms a relief portion 9 on the inner side. A second shoulder bushing 16 is provided in the second through hole. The shoulder of the second shoulder bushing 16 is located in the second countersunk hole. The connecting plate 8 abuts against the head of the second bolt 5 and the second shoulder bushing 16 respectively. The shoulder of the second shoulder bushing 16 abuts against the elastic pad 2 and the nut 6 respectively. That is, the nut 6 indirectly abuts against the elastic pad 2 through the shoulder of the second shoulder bushing 16. In this way, the length of the second shoulder bushing 16 excluding the shoulder corresponds to the length of the second through hole. When the second bolt 5 and the nut 6 are tightened, the head of the second bolt 5 and the nut 6 abut against the second shoulder bushing 16 respectively, and the shoulder of the second shoulder bushing 16 also abuts against the elastic pad 2, thereby limiting the tightening force and preventing the elastic pad 2 from being excessively squeezed or even broken due to excessive tightening of the second bolt 5.

[0027] Please see Figure 1 , Figure 2 and Figure 3 The horn vibration damping mounting structure also includes a controller 17. The frame 1 includes a riser 18 and a beam tube 19. The upper end of the beam tube 19 is connected to the riser 18, and the lower end extends backward at an angle. The horn 3 and the controller 17 are both connected to the beam tube 19. The horn 3 is located above the controller 17 and close to the riser 18. In this way, by adopting the vibration damping mounting structure of this utility model, the vibration of the horn 3 is isolated by the elastic rubber pad 2, which can reduce the interference to the gyroscope in the controller 17 and ensure the stable operation of functions such as TCS and hill start assist.

[0028] Please see Figure 1 , Figure 2 and Figure 3The connecting plate 8 is centered in the width direction of the frame 1, and the other end of the connecting plate 8 extends downward along the beam tube 19. Two first bolts 4 are symmetrically distributed on both sides of the connecting plate 8 along the width direction of the frame 1. In this way, the symmetrical layout aligns the center of gravity of the horn 3 with the mounting point, avoids unbalanced vibration caused by eccentricity due to its own weight, and helps to improve the stability of the shock absorption mounting structure. This ensures that the vibration generated by the horn 3 is absorbed more evenly, thereby further reducing the risk of interference to the controller 17.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
