Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and particularly to a motorcycle. Background Art

[0002] At present, with the continuous increase in the speed of motorcycles, higher requirements are put forward for the high-speed stability and handling stability of vehicles. Therefore, external components such as aerodynamic fins are gradually developed and used on the vehicle body to ensure that the front wheels do not float up when the vehicle is driving at high speed, thereby increasing stability. The rotating fins are adopted in the prior art. Due to the complex structure of the rotating fins and the large number of structural members exposed on the appearance surface, the wind resistance of the fins is large, and the effective windward area for generating downward pressure of the fins is small, resulting in a relatively low downward pressure. Summary of the Invention

[0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a motorcycle, the wind pressure assembly of which can effectively reduce the wind resistance during motorcycle riding and increase the downward pressure during driving.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A motorcycle includes a frame, a suspension assembly, a running assembly, a power system, and a body covering. The suspension assembly is at least partially connected to the frame; the running assembly is connected to the frame through the suspension assembly, and the running assembly includes a front wheel and a rear wheel at least partially located below the frame; the power system is used to drive at least one of the front wheel and the rear wheel; the body covering includes a left guard plate and a right guard plate, the left guard plate and the right guard plate are basically located in the front half of the motorcycle and are at least partially connected to the frame; the motorcycle further includes at least two wind pressure assemblies, one wind pressure assembly is provided on each of the left guard plate and the right guard plate, the power system includes a driving device, the driving device is in transmission connection with the wind pressure assembly, and the driving device can drive the wind pressure assembly to move along the width direction of the motorcycle to increase or decrease the effective windward area of the wind pressure assembly.

[0006] Further, the motorcycle includes a detection mechanism for detecting the rotation speed of the running assembly and transmitting a signal to the driving device, and the driving device controls the telescopic amount of the wind pressure assembly, and the telescopic amount of the wind pressure assembly increases or decreases synchronously with the rotation speed of the running assembly.

[0007] Further, the body covering includes a first covering and a second covering, the first covering and the second covering are detachably connected, and an accommodation space is formed between the first covering and the second covering, and the wind pressure assembly is at least partially located in the accommodation space.

[0008] Further, the first covering member includes a guiding piece hole extending in the width direction of the motorcycle. The wind pressure assembly includes a wind pressure piece body. After the wind pressure piece body passes through the guiding piece hole, the wind pressure piece body moves in the width direction of the motorcycle.

[0009] Further, the wind pressure assembly further includes a connecting plate located in the accommodating space. One side of the connecting plate close to the first covering member is fixedly connected to the wind pressure piece body, and the connecting plate and the wind pressure piece body move synchronously in the width direction of the motorcycle.

[0010] Further, the wind pressure assembly further includes a supporting main board. The second covering member includes a connecting card hole. At least part of the supporting main board penetrates through the connecting card hole, and the supporting main board is fixedly connected to the second covering member. Wherein, a plurality of cylindrical guide rails extending in the width direction of the motorcycle are arranged on the supporting main board, cylindrical guide holes corresponding to the cylindrical guide rails are arranged on the connecting plate, and a positioning groove is arranged on the inner side of the first covering member. After the cylindrical guide rails pass through the cylindrical guide holes, they are clamped with the positioning groove, and the connecting plate can slide on the cylindrical guide rails.

[0011] Further, the driving device is connected to the supporting main board. The driving device includes a threaded column extending in the width direction of the motorcycle. A through hole is arranged on the supporting main board, a threaded hole is arranged on the connecting plate, and after the threaded column passes through the through hole, it is connected to the threaded hole. The rotation of the threaded column drives the movement of the connecting plate. When the threaded column stops rotating, the threaded column locks the movement of the connecting plate.

[0012] Further, when the wind pressure assembly is in the initial position, the wind pressure assembly is basically retracted into the body covering member. When the wind pressure assembly is in the deployed position, the wind pressure assembly extends outward from the body covering member by a preset distance in the width direction of the motorcycle.

[0021] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the specific embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] As Figure 1 and Figure 2 show a motorcycle 100, which includes a frame 11, a suspension assembly 12, a running assembly 13, a power system 14 and a body covering 15. The frame 11 constitutes the basic framework of the motorcycle 100 and is used to support the suspension assembly 12, the running assembly 13, the power system 14 and the body covering 15. The suspension assembly 12 is at least partially connected to the frame 11, and the suspension assembly 12 is used to provide shock absorption and buffering for the motorcycle 100. The running assembly 13 is connected to the frame 11 through the suspension assembly 12, and the running assembly 13 is used for the movement of the motorcycle 100. The power system 14 is used to drive the running assembly 13, and the power system 14 transmits kinetic energy to the running assembly 13 to drive the movement of the running assembly 13. The body covering 15 includes a left guard plate 151 and a right guard plate 152. The left guard plate 151 and the right guard plate 152 are basically located in the front half of the motorcycle 100. The left guard plate 151 and the right guard plate 152 are at least partially connected to the frame 11, and the left guard plate 151 and the right guard plate 152 are used to protect the internal parts of the motorcycle 100. To clearly illustrate the technical solution of the application, the following is also defined as Figure 1Front, rear, left, right, top, and bottom as shown. In this application, the length direction of the motorcycle 100 refers to the aforementioned front-rear direction, the width direction of the motorcycle 100 refers to the aforementioned left-right direction, and the height direction of the motorcycle 100 refers to the aforementioned up-down direction. It should be noted that the traveling assembly 13 includes a front wheel 131 and a rear wheel 132 at least partially located below the frame 11, and both the front wheel 131 and the rear wheel 132 are used for the movement of the motorcycle 100. The left fender 151 is at least partially disposed on the left side of the motorcycle 100, and the right fender 152 is at least partially disposed on the right side of the motorcycle 100. Among them, the body covers 15 on the left side of the motorcycle 100 all belong to the left fender 151, and the body covers 15 on the right side of the motorcycle 100 all belong to the right fender 152.

[0023] As Figure 2 shown, as an implementation, the motorcycle 100 further includes at least two wind pressure components 153. The wind pressure components 153 are used to increase the downward pressure during the running of the motorcycle 100 to enhance the grip of the motorcycle 100, thereby being beneficial to improving the running stability of the motorcycle 100. Specifically, the exposed part of the wind pressure component 153 is basically in a sheet structure, and the maximum surface area of the sheet structure is basically oriented in the height direction of the motorcycle 100. Among them, the lower surface of the wind pressure component 153 has a certain amplitude compared with the upper surface of the wind pressure component 153. Therefore, the air flow velocity on the upper surface of the wind pressure component 153 is relatively fast, while the lower surface of the wind pressure component 153 is almost flat, so the air flow velocity on the upper surface of the wind pressure component 153 is relatively slow. Through the above settings, the pressure on the lower surface of the wind pressure component 153 is low, and the pressure on the upper surface of the wind pressure component 153 is high. Therefore, the wind pressure component 153 will form a downward pressure, that is, the wind pressure component 153 will generate a downward pressure, so that the motorcycle 100 running at high speed is affected by the wind pressure component 153 and is in a stable running state. More specifically, the wind pressure components 153 are both provided on the left fender 151 and the right fender 152. Define a longitudinal plane 101 perpendicular to the width direction of the motorcycle 100 and passing through the width center of the motorcycle 100. The wind pressure components 153 are symmetrically arranged with respect to the longitudinal plane 101. Among them, the number of the wind pressure components 153 on the left fender 151 is equal to the number of the wind pressure components 153 on the right fender 152, so that the downward pressure of the wind pressure components 153 on the left fender 151 of the motorcycle 100 is equal to the downward pressure of the wind pressure components 153 on the right fender 152 of the motorcycle 100, thereby avoiding excessive downward pressure on the left or right side of the motorcycle 100 and causing the motorcycle 100 to shake during running, and further being beneficial to improving the stability performance of the motorcycle 100. In addition, the wind pressure components 153 can be arranged at any position on the left fender 151 and the right fender 152 as needed to meet the running stability of the motorcycle 100.

[0024] As Figure 3As shown, in this embodiment, the wind pressure assembly 153 includes an initial position 154 and a deployed position 155. When the wind pressure assembly 153 is in the initial position 154, the wind pressure assembly 153 is substantially retracted into the body covering 15. When the wind pressure assembly 153 is in the deployed position 155, the wind pressure assembly 153 extends outward from the body covering 15 in the width direction of the motorcycle 100 by a preset distance 102. Specifically, when the motorcycle 100 is idling, due to the relatively heavy mass and large volume of the motorcycle 100 itself, the motorcycle 100 can travel stably on the road surface. At this time, the wind pressure assembly 153 can be housed on the body covering 15 to avoid increasing the windward area of the motorcycle 100 and causing an increase in the wind resistance of the motorcycle 100, thereby facilitating the motorcycle 100 to maintain stability during driving and enabling rapid acceleration. When the speed of the motorcycle 100 increases to a certain extent, the mass of the motorcycle 100 itself is no longer sufficient to enable the motorcycle 100 to travel stably on the road surface. At this time, the wind pressure assembly 153 extends to both sides of the motorcycle 100, so that the wind pressure assembly 153 generates a downward pressure, so that the motorcycle 100 receives the downward pressure of the wind pressure assembly 153, thereby improving the grip of the motorcycle 100 and further improving the stability of the motorcycle 100 during high-speed driving. It should be noted that the wind pressure assembly 153 is arranged to extend in the width direction of the motorcycle 100, so that the wind pressure assembly 153 can respond to the vehicle speed signal of the motorcycle 100 in a timely manner. When the motorcycle 100 goes from idling to high speed, the wind pressure assembly 153 can move from the initial position 154 to the deployed position 155 at the fastest speed and with the least amount of time, so that the motorcycle 100 can continue to travel stably. At the same time, the telescopic amount of the wind pressure assembly 153 can be adjusted in real time according to the driving speed of the motorcycle 100, that is, the telescopic amount of the wind pressure assembly 153 is proportional to the vehicle speed of the motorcycle 100. When the speed of the motorcycle 100 is the highest, the telescopic amount of the wind pressure assembly 153 is the largest. When the speed of the motorcycle 100 gradually decreases, the wind pressure assembly 153 gradually moves from the deployed position 155 to the initial position 154, so that the motorcycle 100 is always in the best driving state. In addition, the windward area of the wind pressure assembly 153 is small, so that the wind resistance borne by the wind pressure assembly 153 is small, so that the motorcycle 100 can basically ignore the influence of the wind resistance brought by the wind pressure assembly 153. Among them, wind resistance refers to the resistance from the air when the vehicle is driving, and the windward area refers to the maximum area of observing the motorcycle 100 in the front-rear direction.

[0025] As Figure 2 and Figure 3As shown, as an implementation, as an implementation, the power system 14 includes a driving device 141, the driving device 141 is in transmission connection with the wind pressure assembly 153, the driving device 141 is located inside the body cover 15, and the driving device 141 can drive the wind pressure assembly 153 to move along the width direction of the motorcycle 100, so that the wind pressure assembly 153 can switch between the initial position 154 and the deployed position 155. Specifically, the driving device 141 drives the wind pressure assembly 153 to move along the width direction of the motorcycle 100 to increase or decrease the effective windward area of ​​the wind pressure assembly 153, wherein the effective windward area of ​​the wind pressure assembly 153 refers to the contact area of ​​the wind pressure assembly 153 with the air during the driving process of the motorcycle 100, and the effective windward area of ​​the wind pressure assembly 153 is proportional to the downforce of the wind pressure assembly 153, that is, the larger the effective windward area of ​​the wind pressure assembly 153, the greater the downforce of the wind pressure assembly 153, and vice versa, the smaller the effective windward area of ​​the wind pressure assembly 153, the smaller the downforce of the wind pressure assembly 153. More specifically, one wind pressure assembly 153 is equipped with one driving device 141, and all driving devices 141 can simultaneously respond to the signal of the motorcycle 100 and work synchronously, so that all wind pressure assemblies 153 can simultaneously move from the initial position 154 to the deployment position 155, so as to improve the consistency of the movement of the wind pressure assembly 153, thereby facilitating the improvement of the intelligence level of the motorcycle 100, and at the same time facilitating the maintenance of the driving stability of the motorcycle 100. It can be understood that arranging the driving device 141 inside the body cover 15 can prevent the driving device 141 from being exposed to the outside of the body and being affected by impact or rain, so as to prevent the driving device 141 from being damaged and stopping working, thereby facilitating the protection of the driving device 141, and at the same time ensuring that the driving device 141 can drive the wind pressure assembly 153 to work normally, thereby facilitating the improvement of the driving stability of the motorcycle 100. In addition, the driving device 141 can be a device such as a motor, as long as it can meet the movement of the wind pressure assembly 153. It should be noted that the motorcycle 100 also includes a detection mechanism 16, which is used to detect the rotation speed of the travel component 13 and transmit a signal to the drive device 141. The drive device 141 controls the extension and retraction amount of the wind pressure component 153 so that the extension and retraction amount of the wind pressure component 153 and the rotation speed of the travel component 13 are synchronously increased or decreased. Specifically, the lower the rotation speed of the travel component 13 and the lower the speed of the motorcycle 100, the shorter the extension length of the wind pressure component 153 and the smaller the downforce generated. Similarly, the higher the rotation speed of the travel component 13 and the higher the speed of the motorcycle 100, the longer the extension length of the wind pressure component 153 and the larger the downforce generated. Through the above-mentioned arrangement, the wind pressure component 153 can be provided with multiple deployment positions 155, thereby providing reasonable downforce according to the needs of the motorcycle 100, which is beneficial to improving the driving stability of the motorcycle 100.

[0026] like Figure 4As shown in the figure. As an implementation, the body covering 15 includes a plurality of first coverings 156 and a plurality of second coverings 157. The first covering 156 and the second covering 157 are detachably connected, and a receiving space 103 is formed between the first covering 156 and the second covering 157. At least a part of the wind pressure assembly 153 is located in the receiving space 103. Specifically, the first covering 156 is located outside the second covering 157. The first covering 156 constitutes the external protection plate of the motorcycle 100, and the second covering 157 constitutes the internal protection plate of the motorcycle 100. By arranging the wind pressure assembly 153 between the first covering 156 and the second covering 157, the first covering 156 and the second covering 157 can provide a supporting force for the wind pressure assembly 153, so that the wind pressure assembly 153 can be stably installed on the vehicle body, which is beneficial to improving the connection stability of the wind pressure assembly 153. At the same time, the structure among the wind pressure assembly 153, the first covering 156 and the second covering 157 is compact, which is further beneficial to improving the structural compactness of the motorcycle 100. It can be understood that both the left fender 151 and the right fender 152 include the first covering 156 and the second covering 157, and the connection manner between the first covering 156 and the second covering 157 can be set as a fixed connection or the like, which is beneficial to improving the connection strength between the wind pressure assembly 153 and the first covering 156 and the second covering 157.

[0027] As an implementation, the first covering 156 includes a guiding piece hole 1561 extending along the width direction of the motorcycle 100. The wind pressure assembly 153 includes a wind pressure piece body 1531. After the wind pressure piece body 1531 passes through the guiding piece hole 1561, the wind pressure piece body 1531 moves along the width direction of the motorcycle 100. Specifically, the wind pressure assembly 153 includes at least one wind pressure piece body 1531. When the number of wind pressure piece bodies 1531 is more than two, the wind pressure piece bodies 1531 can be distributed along the height direction of the motorcycle 100, and a certain distance is maintained between the wind pressure piece bodies 1531, so that the air flow can smoothly pass through the space between the wind pressure piece bodies 1531, so that the wind pressure piece bodies 1531 do not interfere with each other, and the structure between the wind pressure piece bodies 1531 is more compact. It should be noted that the wind pressure piece body 1531 is closely attached to the guiding piece hole 1561, so that the outer surface of the first covering 156 is smooth and flat, which is beneficial to the smooth passing of the air flow over the outer surface of the first covering 156. For example, when the outer surface of the first covering 156 between the wind pressure piece bodies 1531 is recessed inward, the air flow contacting the outer surface of the first covering 156 will form a vortex, which will affect the downward pressure of the wind pressure piece body 1531 and weaken it. Therefore, in this embodiment, the outer surface of the first covering 156 is set as an arc surface or a plane to cooperate with the wind pressure assembly 153, which is beneficial to increasing the downward pressure of the wind pressure assembly 153, and further beneficial to improving the driving stability of the motorcycle 100.

[0028] As an implementation manner, the wind pressure assembly 153 further includes a connecting plate 1532. The connecting plate 1532 is located in the accommodation space 103. The side of the connecting plate 1532 close to the first covering member 156 is fixedly connected to the wind pressure sheet body 1531. The connecting plate 1532 and the wind pressure sheet body 1531 move synchronously along the width direction of the motorcycle 100. Specifically, a connecting portion is provided on the connecting plate 1532, and the wind pressure sheet body 1531 is detachably connected to the connecting portion in a manner of a fastener. When a certain wind pressure sheet body 1531 is damaged, a new wind pressure sheet body 1531 can be directly replaced and then continue to be used. Thereby, it is beneficial to control the cost of the wind pressure assembly 153, and at the same time, it is also beneficial to improve the assembly speed and maintenance efficiency of the wind pressure assembly 153.

[0029] As an implementation manner, the wind pressure assembly 153 further includes a supporting main board 1533. The second covering member 157 includes a connecting card hole 1571. At least a part of the supporting main board 1533 passes through the connecting card hole 1571, and the supporting main board 1533 is fixedly connected to the second covering member 157. Specifically, the supporting main board 1533 is detachably connected to the second covering member 157 in a connection manner of a fastener. The driving device 141 is connected to the supporting main board 1533. The driving device 141 and the connecting plate 1532 are respectively located on both sides of the supporting main board 1533. The supporting main board 1533 is used to support the driving device 141 and the connecting plate 1532. Through the above arrangement, the connection strength of the supporting main board 1533, the driving device 141 and the connecting plate 1532 is relatively high. Thereby, it is beneficial to improve the connection stability of the supporting main board 1533, the driving device 141 and the connecting plate 1532, and further beneficial to improve the structural stability of the wind pressure assembly 153.

[0030] As an implementation, the driving device 141 includes a threaded post 1534 extending in the width direction of the motorcycle 100. A through hole 1533a is provided on the supporting main board 1533, and a threaded hole 1532a is provided on the connecting plate 1532. After the threaded post 1534 passes through the through hole 1533a, it is connected to the threaded hole 1532a. The rotation of the threaded post 1534 can drive the movement of the connecting plate 1532, so that the connecting plate 1532 drives the air pressure sheet 1531 to move. Specifically, the threaded post 1534 is used to transmit the power of the driving device 141, that is, the rotation of the driving device 141 drives the rotation of the threaded post 1534. Since the position of the threaded post 1534 does not change during the rotation process, and the rotation axis of the threaded post 1534 extends in the width direction of the motorcycle 100, the connecting plate 1532 provided with the threaded hole 1532a will move in the width direction of the motorcycle 100 as the connecting post rotates, so as to realize the movement of pushing the air pressure sheet 1531. When the threaded post 1534 stops rotating, the threaded post 1534 can lock the movement of the connecting plate 1532, so that the connecting plate 1532 is in a static state. Through the above settings, the connecting plate 1532 can control the telescopic amount of the air pressure sheet 1531 according to the number of turns of the threaded post 1534, so that the air pressure sheet 1531 can control its own telescopic length according to the speed of the vehicle, which is beneficial to controlling the air pressure sheet 1531 to generate a downward pressure to improve the driving stability of the motorcycle 100.

[0031] As an implementation, a plurality of cylindrical guide rails 1533b extending in the width direction of the motorcycle 100 are provided on the supporting main board 1533, cylindrical guide holes 1532b corresponding to the cylindrical guide rails 1533b are provided on the connecting plate 1532, and a positioning groove 1562 is provided inside the first cover 156. After the cylindrical guide rail 1533b passes through the cylindrical guide hole 1532b, it is clamped with the positioning groove 1562, and the connecting plate 1532 can slide on the cylindrical guide rail 1533b. Specifically, the outer surface of the cylindrical guide rail 1533b is attached to the inner surface of the cylindrical guide hole 1532b. When the driving device 141 drives the threaded post 1534 to rotate, the cylindrical guide hole 1532b can slide on the cylindrical guide rail 1533b, so that the connecting plate 1532 moves in the width direction of the motorcycle 100, and the cylindrical guide rail 1533b can limit the movement of the connecting plate 1532 in other directions, which is beneficial to improving the guiding property of the air pressure assembly 153. At the same time, the connecting post is also beneficial to improving the stability of the connecting plate 1532 and the air pressure sheet 1531, and further beneficial to improving the structural stability of the air pressure assembly 153.

[0032] As an implementation, the wind pressure assembly 153 further includes a wind deflector 1535. The wind deflector 1535 is connected to the side of the wind pressure sheet 1531 away from the connecting plate 1532. The wind deflector 1535 can move along the width direction of the motorcycle 100 with the wind pressure sheet 1531. When the wind pressure assembly 153 is in the initial position 154, the wind deflector 1535 is basically retracted into the body cover 15, that is, the wind deflector 1535 is basically flush with the body cover 15. Specifically, the wind deflector 1535 is arranged on the outermost side of the wind pressure sheet 1531. The wind pressure sheet 1531 can drive the wind deflector 1535 to move in the width direction of the motorcycle 100. The wind deflector 1535 can improve the connection strength between the wind pressure sheets 1531, thereby improving the stability during the movement of the wind pressure sheets 1531, enabling the wind pressure sheets 1531 to have a stable downward pressure, and further facilitating the improvement of the stability of the motorcycle 100 during driving. It can be understood that receiving grooves can also be provided on the left guard plate 151 and the right guard plate 152 so that the wind deflector 1535 can just be clamped in the receiving grooves, which is conducive to improving the connection strength between the wind deflector 1535 and the left guard plate 151 and the right guard plate 152. In addition, the wind deflector 1535 can also protect the wind pressure sheets 1531 to prevent the wind pressure sheets 1531 from being damaged by impact, and further facilitating the improvement of the service life of the wind pressure sheets 1531.

[0033] As Figure 3 shown, as an implementation, the wind pressure assembly 153 further includes a motor protection cover 1536. The motor protection cover 1536 is located on the side of the second cover 157 away from the second cover 157. The motor protection cover 1536 is connected to the second cover 157. At least part of the driving device 141 is located between the motor protection cover 1536 and the second cover 157. Specifically, a storage space is formed in the motor protection cover 1536. At least part of the driving device 141 is located in the storage space, and the sealing performance between the storage space and the second cover 157 is good, so that rainwater and dust can be prevented from directly contacting the driving device 141, and further facilitating the improvement of the service life of the driving device 141.

[0034] As an implementation, the length L1 of the preset distance 102 can be set to be greater than or equal to 30 mm and less than or equal to 150 mm. Further, the length L1 of the preset distance 102 can be set to be greater than or equal to 60 mm and less than or equal to 120 mm. Even further, the length L1 of the preset distance 102 can be set to 90 mm. Through the above settings, it is possible to avoid the volume of the wind pressure sheet 1531 being too large due to the excessive length L1 of the preset distance 102, so as to prevent the wind pressure assembly 153 from occupying a large body space, thereby facilitating the improvement of the structural compactness of the wind pressure assembly 153; and it is also possible to avoid the downward pressure of the wind pressure sheet 1531 being too small due to the excessive short length L1 of the preset distance 102, so as to prevent the motorcycle 100 from shaking during driving, and further facilitate the improvement of the driving stability of the motorcycle 100. It should be noted that the length of the wind pressure sheet 1531 is slightly greater than the length of the preset distance 102, so that the volume of the wind pressure sheet 1531 can be smaller, thereby facilitating the improvement of the space utilization rate of the motorcycle 100.

[0035] It should be understood that for those of ordinary skill in the art, improvements or changes can be made according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of the present invention.
