Description

Technical Field

[0001] The present application relates to the field of driving tools, and in particular to a snowmobile. Background Art

[0002] A snowmobile is a special vehicle that can be used for snow rescue, transportation and entertainment. It is usually a sled at the front and a track at the rear, and can move quickly in the snow.

[0003] In order to improve the maneuverability, the existing snowmobiles have simplified their structures. As a result, when the existing snowmobiles are driven at high speed on undulating snow, they often experience large bumps. Due to the simplified structure, the existing snowmobiles have poor shock absorption effect, which easily causes the driver to experience large bumps with the vehicle, thereby affecting the driver's driving experience. Moreover, when the vehicle speed is high, the driver may be thrown out of the vehicle, causing a safety accident. Summary of the invention

DETAILED DESCRIPTION

[0067] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0068] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present application.

[0069] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0070] One of the preferred embodiments of the present application is as follows: Figures 1 to 13 As shown, a snowmobile comprises a frame assembly 1, a drive assembly 2, a front suspension assembly 3 and a pair of snowboards 5. The drive assembly 2 is mounted on the rear of the frame assembly 1 to drive the snowmobile to travel on the snow; the front suspension assembly 3 is mounted on both sides of the front of the frame assembly 1 and is connected to the snowboards 5 respectively. When bumps occur, the drive assembly 2 can be extended and retracted in the bump direction to reduce the bump amplitude of the frame assembly 1; at the same time, the front suspension assembly 3 can be deflected by the impact force received and drive the snowboard to swing, so as to generate limiting resistance in the vertical driving direction to improve the grip of the snowmobile, so as to ensure that the snowmobile maintains stable driving and avoids side slipping when bumps occur.

[0071] It is understandable that when a snowmobile is traveling, when bumps occur, the snowmobile may easily slip due to the small friction of the snow, thereby affecting the driving stability of the snowmobile. Therefore, by extending and retracting the driving assembly 2 in the bump direction, the bump vibration of the snowmobile can be reduced to a certain extent. At the same time, the swinging of the sled board 5 can form a gripping force perpendicular to the traveling direction with the snow, thereby generating a limiting force in the side slip direction of the snowmobile to reduce or avoid side slip.

[0072] In this embodiment, Figure 1 , Figures 3 to 5 As shown, the driving assembly 2 includes a driving component installed on the frame assembly 1, a traveling component and a crawler 23. The crawler 23 is installed on the traveling component and has a polygonal structure. The traveling component is connected to the driving component so that the traveling component, driven by the driving component, travels along the snow through the bottom edge of the crawler 23. When bumps occur, the bottom edge of the traveling component can be extended and retracted in the bump direction, and the circumference of the polygonal structure formed by the crawler 23 can be ensured to remain unchanged.

[0073] It is understandable that when the existing tracked snowmobile is bumped and the shock-absorbing structure is used to absorb shock, the track 23 of the snowmobile is in a continuous loose state during the deformation and shock absorption process of the traveling component, and it is easy for the traveling component and the track 23 to slip, thereby affecting the driving stability of the snowmobile. In this embodiment, the perimeter of the polygonal structure formed by the track 23 can be kept unchanged by the traveling component extending and retracting along the bumping direction, that is, the track 23 is always kept in a tensioned state during the bumping process of the traveling component.

[0074] Specifically, Figures 3 to 5 As shown, the traveling assembly includes at least one set of driving wheels 21, two sets of driven wheels 22 and a tensioning assembly. The driving wheel 21 is rotatably mounted on the frame assembly 1 through a rotating shaft, and the two sets of driven wheels 22 are spaced and connected by a connecting plate 24 and are located at the lower part of the driving wheel 21. The connecting plate 24 can be connected to the frame assembly 1 through a tensioning assembly. The track 23 is sequentially sleeved on the driving wheel 21 and the driven wheel 22 to form a polygonal structure. Therefore, when bumps occur, the driven wheel 22 can be driven by the tensioning assembly to deflect and rotate in the bumping direction at the same time, so that the traveling assembly can ensure that the track 23 is always tensioned while performing shock absorption.

[0075] It is understandable that the rotation of the driven wheel 22 in the bumping direction can be used to absorb the bumping impact, so as to ensure that the impact force on the driving wheel 21 and the frame assembly 1 connected to the driving wheel 21 is reduced, thereby achieving shock absorption of the bumping. The deviation of the driven wheel 22 in the bumping direction can ensure that the track 23 is always in a tensioned connection state with the driving wheel 21 and the driven wheel 22 when the driven wheel 22 deflects, so as to prevent the track 23 from slipping.

[0076] In this embodiment, Figures 3 to 5 As shown, the tensioning assembly includes at least one pair of elastic assemblies 6, and the two elastic assemblies 6 of each pair are arranged in an inverted "eight" shape, the upper end of the elastic assembly 6 is hinged to the frame assembly 1, and the lower end of the elastic assembly 6 is hinged to the connecting plate 24. When bumps occur, the two elastic assemblies 6 of each pair can be deflected in the bump direction around the hinge position with the frame assembly 1; at the same time, in each pair of elastic assemblies 6, the elastic assembly 6 close to the bump position is stretched, and the elastic assembly 6 away from the bump position is contracted; thereby, the connecting plate 24 can be driven to drive the driven wheel 22 to deflect and rotate in the bump direction.

[0077] It is understandable that, for the sake of convenience, the specific working process of the travel component can be described. For the sake of convenience, a group of driven wheels 22 located in the front of the travel direction can be set as the first driven wheel, and the other group of driven wheels 22 can be set as the second driven wheel; at the same time, the elastic component 6 close to the front of the travel direction can be set as the first elastic component, and the other elastic component can be set as the second elastic component.

[0078] The tensioning sections of the tracks 23 of the two sets of driven wheels 22 are the bottom edges of the polygonal structure, and the snowmobile can travel on the snowy ground through the tensioning sections of the tracks 23 of the two sets of driven wheels 22.

[0079] When the snowmobile travels on an undulating road surface, the first driven wheel will first pass through the undulating road surface, so that the first driven wheel will be subjected to an impact force that is tilted upward away from the driving direction, and the vertical component of the impact force can drive the first driven wheel to rotate with the second driven wheel as the center and the connecting plate 24 as the radius. And during the rotation of the first driven wheel, the impact force can be transmitted to the elastic component 6 through the connecting plate 24. According to the different tilt directions of the elastic component 6, the first elastic component can rotate around the upper end hinge position under the action of the impact force, and during the rotation process, it can be extended at the same time according to the position change of the connecting plate 24. The second elastic component contracts under the impact force and the elastic force of the first elastic component, so that the two groups of driven wheels 22 can move horizontally away from the driving direction according to the horizontal component of the impact force and the horizontal component of the elastic force of the first elastic component; in this process, the second elastic component can rotate synchronously along the bumpy direction.

[0080] That is, at the moment of being bumped, the whole formed by the two sets of driven wheels 22 through the connecting plate 24 moves and rotates at the same time. As a result, the length of the side adjacent to the bottom and located in the front of the driving direction in the polygonal structure is shortened, and the length of the side adjacent to the bottom and located in the rear of the driving direction is extended, thereby ensuring that the circumference of the polygonal structure formed by the track 23 being tensioned with the driving wheel 21 and the driven wheel 22 remains unchanged during the bumping process, that is, the track 23 is always tensioned during the bumping process.

[0081] As the snowmobile continues to move, and the undulating position of the snow is located before the midpoint of the connecting plate 24, the angle of rotation of the first driven wheel around the second driven wheel continues to increase, and at the same time, the horizontal movement distance of the whole formed by the two sets of driven wheels 22 and the connecting plate 24 away from the driving direction gradually increases; the first elastic component and the second elastic component synchronously perform adaptive changes.

[0082] As the snowmobile continues to move, at the moment when the undulating position of the snow passes the midpoint of the connecting plate 24, the horizontal movement of the first elastic component and the second elastic component and the driven wheel 22 remain unchanged; but the whole formed by the driven wheel 22 and the connecting plate 24 rotates in the opposite direction with the undulating position as the fulcrum, so that the first driven wheel contacts the snow and the second driven wheel is lifted; and in the subsequent driving process, the two sets of driven wheels 22 and the first elastic component and the second elastic component are reset to the initial state.

[0083] In this embodiment, the extension lines of the two elastic components 6 of each pair along the setting direction intersect with the connection line between the two sets of driven wheels 22. This ensures that when bumps occur, the impact force received by the driven wheels 22 can drive the elastic components 6 to expand and rotate along the bump direction.

[0084] It can be understood that by making the extension lines of the elastic component 6 along the setting direction intersect with the line between the two groups of driven wheels 22, it can be ensured that the impact force exerted on the driven wheel 22 is always offset from the extension direction of the elastic component 6, thereby allowing the elastic component 6 to be subjected to force smoothly.

[0085] In this embodiment, Figures 3 to 5 As shown, two groups of driven wheels 22 are correspondingly rotatably installed at the two ends of the connecting plate 24, the lower end of the elastic component 6 is hinged to the connecting plate 24, and the hinge position of the elastic component 6 and the connecting plate 24 is located at the midpoint of the entire traveling component, thereby improving the supporting stability of the elastic component 6 on the driven wheels 22.

[0086] In this embodiment, Figure 3 As shown, the elastic component 6 includes a telescopic rod 61 and a spring 62. The upper end of the telescopic rod 61 is hinged to the frame component 1, and the lower end of the telescopic rod 61 is hinged to the connecting plate 24. The spring 62 is sleeved on the telescopic rod 61 and respectively abuts against the upper end and the lower end of the telescopic rod 61. When bumps occur, the telescopic rod 61 can be extended to achieve the deformation of the spring 62, thereby reducing the shock of the travel component.

[0087] Specifically, Figure 3 As shown, the telescopic rod 61 includes a first guide rod 611 and a second guide rod 612, the first guide rod 611 and the second guide rod 612 are slidably connected, the upper end of the first guide rod 611 is hinged to the frame assembly 1, the lower end of the second guide rod 612 is hinged to the connecting plate 24, one end of the spring 62 abuts against the first guide rod 611, and the other end of the spring 62 abuts against the second guide rod 612. Therefore, when bumps occur, the first guide rod 611 and the second guide rod 612 slide relative to each other, thereby realizing elastic deformation of the spring 62 for shock absorption.

[0088] In this embodiment, there are multiple ways to set the specific number of groups of driving wheels 21, including but not limited to the following two.

[0089] Method 1: Figure 5 As shown, the driving wheel 21 is a group, so that the driving wheel 21 and the driven wheel 22 can form a triangular structure through the track 23. The two groups of driven wheels 22 can be moved horizontally in the opposite direction of the travel through the connecting plate 24 to

[0090] Method 2: Figure 4 As shown, there are two sets of driving wheels 21, and the two sets of driving wheels 21 are installed on the frame assembly 1 at intervals, so that a quadrilateral structure is formed between the driving wheels 21 and the driven wheels 22 through the crawler tracks 23.

[0091] In this embodiment, there are multiple ways to drive the travel component. For example, the driving component is an engine, which is installed on the frame component 1 and connected to the rotating shaft of the driving wheel 21 through a transmission shaft, thereby driving the snowmobile to travel. For another example, the driving component includes a motor and a battery pack, the motor is installed on the frame component 1 and connected to the rotating shaft of the driving wheel 21 through a transmission shaft, a battery compartment 120 is provided on the frame component 1, and the battery pack is installed in the battery compartment 120 to power the motor, thereby driving the snowmobile to travel.

[0092] One of the embodiments of the present application is as follows: Figure 1 , Fig.10 and Fig.11 As shown, the snowmobile further includes a steering assembly 4 installed at the front end of the frame assembly 1. The steering assembly 4 includes a driving part and a traction part; the driving part is installed at the upper part of the frame assembly 1, and the traction part is rotatably installed at the lower part of the frame assembly 1 and is respectively connected to the snowboards 5 on both sides; the driving part and the traction part are connected through a reversing structure; the driving part is suitable for driving the traction part to rotate in a circle to drive the snowboards 5 to rotate synchronously, thereby adjusting the driving direction of the snowmobile; at the same time, the driving part can also adjust the angle between the driving part and the frame assembly 1 through the reversing structure to facilitate the use of the user.

[0093] It is understandable that, since each person has different heights and body shapes, each person has different driving habits. In order to facilitate the snowmobile of the present application to adapt to the use of users with different driving habits, a reversing structure can be provided to connect the driving part and the traction part. Thus, the angle between the driving part and the frame assembly 1 can be adjusted by the reversing structure to adapt to users with different driving habits, and the connection stability between the driving part and the traction part can also be ensured.

[0094] In this embodiment, there are many specific structures of the switching structure, including but not limited to the following two.

[0095] Structure 1, such as Fig.10 and Fig.11 As shown, the reversing structure includes a rotating seat 400 disposed at the lower end of the driving part and the upper end of the traction part, and the driving part and the traction part are rotatably connected through the rotating seat 400. Therefore, when adjusting the angle between the driving part and the frame assembly 1, the user can rotate the driving part around the rotating seat 400 until the angle between the driving part and the frame assembly 1 meets the user's driving habits, and then the rotating seat 400 can be locked by a fastener.

[0096] Structure 2, such as Fig.10 and Fig.11 As shown, the reversing structure includes a universal coupling 800 and a fixing seat 114; the fixing seat 114 is rotatably mounted on the frame assembly 1, the driving part is rotatably connected to the fixing seat 114, and the lower end of the driving part is hinged to the upper end of the traction part through the universal coupling 800. When the user needs to adjust the angle between the driving part and the frame assembly 1, the user can rotate the fixing seat 114 around the installation position, thereby driving the driving part and the upper part of the universal coupling 800 to rotate synchronously until the angle between the driving part and the frame assembly 1 meets the user's driving habits, and then the fixing seat 114 can be locked by fasteners.

[0097] It can be understood that there are two main ways for the driving part to drive the traction part to rotate. In the first way, the driving part drives the traction part to rotate in a circle by swinging around the circumference of the traction part. In the second way, the driving part can drive the traction part to rotate by rotating around its own axis. For the first way, the reversing structure of the above-mentioned structure one is generally adopted; for the second way, the reversing structure of the above-mentioned structure two is generally adopted.

[0098] In this embodiment, Figure 1 , Fig.10 and Fig.11 As shown, the driving part is tilted, and the reversing structure includes a universal coupling 800, a fixed seat 114 and an adjusting component 43. The fixed seat 114 is fixedly mounted on the frame assembly 1, and the upper end of the fixed seat 114 is perpendicular to the driving part. The adjusting component 43 is rotatably mounted on the upper end of the fixed seat 114 and connected to the lower end of the driving part through the rotating seat 400. The traction part is located at the lower end of the fixed seat 114 and is connected to the adjusting component 43 through the universal coupling 800. When the user needs to adjust the angle between the driving part and the frame assembly 1, the driving part can be driven to swing around the adjusting component 43 to drive the adjusting component 43 to rotate circumferentially around its own axis, and then the traction part is driven to rotate circumferentially around its own axis through the universal coupling 800 to achieve control of the driving direction of the snowmobile.

[0099] It is understandable that the initial state of the driving unit is a tilt setting at a specific angle, and the tilt at this specific angle can already meet the normal use of most users. Therefore, by fixing the fixing seat 114, and the upper end surface of the fixing seat 114 is perpendicular to the driving unit, the stability of the installation structure of the driving unit can be ensured by the fixed setting of the fixing seat 114. On this basis, in order to meet the angle adjustment needs of a small number of people, the adjustment component 43 can be set to connect with the driving unit through a fastenable rotating seat 400 to meet the use of a specific group of people.

[0100] In this embodiment, Figure 6 , Figure 7 , Fig.10 and Fig.11 As shown, the traction part includes a rotating shaft 44 and a traction rod 45. The rotating shaft 44 is vertically rotatably connected to the frame assembly 1, the middle part of the traction rod 45 is fixedly connected to the lower end of the rotating shaft 44, and the two ends of the traction rod 45 are connected to the sled 5, so that the driving part can drive the rotating shaft 44 to rotate in a circle, so as to drive the traction rod 45 to drive the sled 5 to rotate around the front suspension assembly, so as to control the driving direction of the snowmobile.

[0101] In this embodiment, Figure 1 , Fig.10 and Fig.11 As shown, the driving part includes an armrest 41 and a driving rod 42. The armrest 41 is fixed to the upper end of the driving rod 42, and the lower end of the driving rod 42 is connected to the traction part through a reversing structure. Therefore, during driving, the user can drive the driving rod 42 to drive the traction part to rotate by operating the armrest 41.

[0102] One of the embodiments of the present application is as follows: Figures 6 to 9 As shown, the front suspension assembly 3 includes a support assembly and an elastic assembly 6 arranged on both sides of the frame assembly 1; the upper end of the support assembly is hinged to the frame assembly 1, and the lower end of the support assembly is hinged to the sled 5; the upper end of the elastic assembly 6 is hinged to the frame assembly 1, and the lower end of the elastic assembly 6 is hinged to the support assembly; a four-bar mechanism is formed between the support assembly, the frame assembly 1 and the sled 5. When bumps occur, the support assembly can deflect around the hinge position at the upper end, thereby driving the corresponding sled 5 to swing; at the same time, the elastic assembly 6 can elastically expand and contract with the deflection of the support assembly, thereby achieving shock absorption.

[0103] It is understandable that there are two main situations in which the snowmobile bumps. First, during the driving of the snowmobile, the sled board 5 bumps over the undulating snow surface; second, during the driving of the snowmobile, the traveling component bumps over the undulating snow surface.

[0104] like Fig. 9As shown, when the sled 5 encounters bumps on the undulating snow surface, the sled 5 drives the support assembly to deflect around the upper hinge position under the action of the impact force, and then the sled 5 can be driven to swing synchronously through the deflection of the support assembly, so that the sled 5 changes from a state parallel to the snow surface to a state inclined to the snow surface, and then the sled 5 can be inserted into the snow obliquely. Therefore, the snow surface can generate resistance perpendicular to the driving direction to the sled 5 to prevent the snowmobile from skidding.

[0105] When the travel assembly bumps, the snowmobile as a whole is in an up-and-down state, so that the support assemblies on both sides of the frame assembly 1 can be synchronously deflected around the upper end, thereby driving the sleds 5 on both sides of the frame assembly 1 to swing toward or away from each other synchronously to form an "eight"-shaped structure and insert into the snow. Therefore, the snow surface can generate resistance perpendicular to the travel direction to the sleds 5 and point them toward the snowmobile, thereby preventing the snowmobile from skidding during bumpy travel.

[0106] It can be described by parameters, such as Fig. 9 As shown, when the sled 5 is in a horizontal state, the sled 5 corresponds to the pressure F of the snow and moves vertically downward, so that the snow can generate an equal and opposite supporting force to balance the weight of the snowmobile. At this time, the resistance of the snow to the snowmobile deviating from the driving direction is f=μF, where μ is the friction coefficient between the snow and the sled. When the sled 5 swings, the pressure of the sled 5 on the snow can be decomposed into a horizontal force F1 and a vertical force F2. At this time, the resistance of the snow to the snowmobile deviating from the driving direction is f=μF2+F1.

[0107] It can be understood that when the snowmobile is traveling on the snow, the snow that the snowmobile has traveled over is compacted under the pressure of the snowmobile, so that when the snowmobile bumps, the inclination of the sled board 5 can effectively block the compacted snow that deviates from the traveling direction, that is, F1 can basically be achieved in actual conditions.

[0108] In this embodiment, Figure 6 As shown, the elastic component 6 includes a telescopic rod 61 and a spring 62. The upper end of the telescopic rod 61 is hinged to the frame component 1, and the lower end of the telescopic rod 61 is hinged to the support component. The spring 62 is sleeved on the telescopic rod 61 and respectively abuts against the upper and lower ends of the telescopic rod 61. When bumps occur, the telescopic rod 61 can be extended and retracted to achieve the deformation of the spring 62, thereby reducing the bumps of the snowmobile.

[0109] Specifically, Figure 6As shown, the telescopic rod 61 includes a first guide rod 611 and a second guide rod 612, the first guide rod 611 and the second guide rod 612 are slidably connected, the upper end of the first guide rod 611 is hinged to the frame assembly 1, the lower end of the second guide rod 612 is hinged to the support assembly, one end of the spring 62 abuts against the first guide rod 611, and the other end of the spring 62 abuts against the second guide rod 612. Therefore, when bumps occur, the first guide rod 611 and the second guide rod 612 slide relative to each other, thereby realizing elastic deformation of the spring 62 for shock absorption.

[0110] In this embodiment, Figure 6 and Fig. 9 As shown, the support assembly includes a first fork arm 31 and a second fork arm 32, the upper ends of the first fork arm 31 and the second fork arm 32 are both hinged to the frame assembly 1, and the lower ends of the first fork arm 31 and the second fork arm 32 are both hinged to the sled 5; the first fork arm 31 is located above the second fork arm 32, and the first fork arm 31 and the second fork arm 32 have different lengths. Therefore, when bumps occur, the first fork arm 31 and the second fork arm 32 can drive the sled 5 to swing by deflecting around the upper end hinge position.

[0111] It is understandable that when the first fork arm 31 and the second fork arm 32 are installed, the upper end and the lower end of the first fork arm 31 and the second fork arm 32 are generally flush in the vertical direction. If the lengths of the first fork arm 31 and the second fork arm 32 are equal, a four-bar mechanism in the shape of a parallelogram can be formed between the first fork arm 31, the second fork arm 32, the frame assembly 1 and the snowboard 5, and then when the first fork arm 31 and the second fork arm 32 are deflected around the upper end, the snowboard 5 will move up or down synchronously in a horizontal posture, so that the snowmobile is easy to slide sideways when bumping. In the present application, by setting the lengths of the first fork arm 31 and the second fork arm 32 to be different, the first fork arm 31 and the second fork arm 32 can drive the snowboard 5 to tilt and swing while moving up or down when deflecting, and then generate resistance perpendicular to the driving direction between the snow and the snow to prevent the snowmobile from sliding sideways when bumping.

[0112] It can also be understood that if the lengths of the first fork arm 31 and the second fork arm 32 are equal, the first fork arm 31 and the second fork arm 32 can be non-aligned in the vertical direction by arranging the installation positions of at least one section of the first fork arm 31 and the second fork arm 32 to tilt and swing while the first fork arm 31 and the second fork arm 32 are deflected.

[0113] In this embodiment, Figure 7 and Figure 8As shown, the support assembly also includes a connecting assembly 7, which is mounted on the sled 5; the lower ends of the first fork arm 31 and the second fork arm 32 are both hinged to the connecting assembly 7. When bumps occur, the first fork arm 31 and the second fork arm 32 deflect around the hinged position at the upper end to drive the connecting assembly 7 to drive the sled 5 to swing. At the same time, the traction part is also connected to the sled 5 through the connecting assembly 7, so that the tilting and swinging of the sled 5 will not interfere with the traction part.

[0114] It is understandable that the sled 5 can be rotated in the horizontal plane under the drive of the traction part to realize the steering control of the snowmobile. When the front suspension assembly 3 is bumpy, the swing direction of the sled 5 is the vertical swing. If the traction part and the first fork arm 31 and the second fork arm 32 are directly connected to the sled 5, the tilting swing of the sled 5 will interfere with the connection of the traction part. Therefore, the present application can avoid the occurrence of interference by setting the connection component 7.

[0115] Specifically, Figure 7 and Figure 8 As shown, the connection assembly 7 includes a first connection component 71 and a pair of second connection components 72. The lower end of the first connection component 71 is hinged to the sled 5 so that the sled 5 can swing forward and backward. A pair of aligned second connection parts 711 are vertically arranged on one side of the first connection component 71. The second connection component 72 is vertically rotated and installed on the second connection part 711 accordingly. The second connection component 72 located at the upper part is hinged to the first fork arm 31 in the horizontal direction, and the second connection component 72 located at the lower part is hinged to the second fork arm 32 in the horizontal direction. At the same time, the first connection component 71 is provided with a first connection part 710 at a position deviated from the second connection part 711. The first connection part 710 is ball-jointed to the traction rod 45 so that the steering and swinging processes of the sled 5 do not interfere with each other.

[0116] It is understandable that when the driving assembly is bumpy, the snowmobile as a whole is in a state of swinging back and forth. Through the hinge of the first connecting part 71 and the sled 5, it can be ensured that the sled 5 remains flush in the front-to-back direction during the back-and-forth swinging of the snowmobile, thereby improving the driving stability of the snowmobile.

[0117] When the first fork arm 31 and the second fork arm 32 are deflected, the sled board 5 can be tilted and swung by the two second connecting parts 72 rotating around the lower ends of the first fork arm 31 and the second fork arm 32. In this process, the first connecting part 71 can rotate with the sled board 5 around the ball joint position of the first connecting part 711 with the traction plate 45. This ensures that the traction rod 45 does not interfere with the first connecting part 71.

[0118] When the snowmobile needs to be turned, the rotation of the rotating shaft 44 can drive the traction rod 45 to pull the sled board 5 to rotate around the second connecting component 72 to vertically rotate the installation position, thereby achieving direction control of the snowmobile.

[0119] In this embodiment, there are multiple ways to install the elastic component 6, including but not limited to the following three.

[0120] Method 1: The lower end of the elastic component 6 is hinged to the first fork arm 31, and the upper hinge positions of the elastic component 6 and the first fork arm 31 are offset. Thus, when bumps occur, the elastic component 6 and the first fork arm 31 can be prevented from being concentrically deflected, thereby failing to achieve elastic shock absorption.

[0121] Mode 2: The lower end of the elastic component 6 is hinged to the second fork arm 32, and the upper end hinge positions of the elastic component 6 and the second fork arm 32 are offset. Thus, when bumps occur, the elastic component 6 and the second fork arm 32 can be prevented from being concentrically deflected, thereby failing to achieve elastic shock absorption.

[0122] Method 3: The lower end of the elastic component 6 is hinged to the connecting component 7, and the elastic component 6 is not aligned with the first fork arm 31 and the second fork arm 32. Therefore, when bumps occur, the elastic component 6 and the first fork arm 31 or the second fork arm 32 can be prevented from being deflected concentrically, thereby failing to achieve elastic shock absorption.

[0123] It is understandable that the specific installation method of the elastic component 6 can be selected by those skilled in the art according to actual needs. Figure 6 As shown, the upper end of the elastic component 6 is hinged to the frame component 1 and is flush with the upper end of the first fork arm 31 ; the lower end of the elastic component 6 is hinged to one end of the second fork arm 32 close to the connecting component 7 .

[0124] One of the embodiments of the present application is as follows: Figure 1 and Figure 2 As shown, the frame assembly 1 includes a frame body 11 and a backing plate 12. The driving assembly 2, the front suspension assembly 3 and the steering assembly 4 are all installed on the frame body 11; the backing plate 12 is detachably covered on the upper end of the frame body 11 for the driver to sit on.

[0125] It is understandable that the frame body 1 and the backing plate 12 are detachably installed, which can facilitate assembly and processing.

[0126] In this embodiment, Figure 2As shown, a mounting area 110 is provided at the rear of the frame body 11, the lower part of the mounting area 110 is used to install the travel component, and a support plate 111 is provided at the upper part of the mounting area 110, and the support plate 111 is used to support the pad 12 to improve the stability of the frame body 1 to the pad 12, and the support plate 111 can also improve the overall rigidity of the frame body 11.

[0127] It is understandable that the support plate 111 can be a single piece, and the extension length of the support plate 111 is close to or equal to the length of the installation area 110. This can achieve full coverage of the installation area 110, thereby effectively improving the support strength of the pad 12 and improving the overall rigidity of the frame body 11. Figure 2 As shown, there may be multiple support plates 111, and the multiple support plates 111 are arranged at equal intervals in the installation area 110. The installation area 110 is fully covered by the multiple support plates 111.

[0128] In this embodiment, Figure 2 As shown, the battery compartment 120 is provided at the front of the frame body 11 for placing the battery pack. The battery compartment 120 and the mounting area 110 can be used to reasonably distribute the overall structure of the drive assembly 2, thereby ensuring that the overall total amount of the drive assembly 2 is evenly distributed on the frame body 11, thereby improving the driving stability of the snowmobile.

[0129] Understandably, if the mass of a snowmobile is unevenly distributed, there will be a lack of grip in areas where the weight is lighter, which can cause skidding.

[0130] In this embodiment, Figure 2 As shown, a front anti-collision beam 112 and a rear anti-collision beam 113 are detachably mounted on the front and rear ends of the frame body 11 , respectively. The front anti-collision beam 112 and the rear anti-collision beam 113 can effectively improve the strength and rigidity of the frame body 11 .

[0131] It is understandable that the overall structure of the frame body 11 is formed by two cross frames and a plurality of longitudinal frames connected by bolts or welded. The front and rear ends of the two cross beams are respectively connected by the integrally formed front anti-collision beam 112 and rear anti-collision beam 113, which can effectively improve the overall rigidity of the frame body 11, so that when bumps occur, the fatigue wear degree of the welding or bolting positions of the cross beams and longitudinal beams can be reduced, thereby ensuring the service life of the frame body 11, and at the same time, it can also improve the driving stability of the frame assembly 1.

[0132] In this embodiment, Figure 1 As shown, a snow guard 14 is installed at the rear end of the frame body 11, and the snow guard 14 is located above the traveling component, so that when the traveling component is traveling, the snow guard 14 can block the snow splashed by the traveling component.

[0133] In this embodiment, Figure 1 As shown, a cover plate 13 is installed at the front end of the frame body 11, and the cover plate 13 is suitable for covering the steering assembly 4, thereby preventing the steering assembly 4 from being blocked by accumulated snow during driving.

[0134] In this embodiment, Figure 2 As shown, the front anti-collision beam 112 and the rear anti-collision beam 113 are both tilted upward. The front anti-collision beam 112 can protect the front cover plate 13 through the tilting structure. At the same time, when the front anti-collision beam 112 collides, the collision force can be decomposed into horizontal force and vertical force, thereby reducing the damage to the driver caused by the collision impact force. The tilting of the rear anti-collision beam 113 can not only prevent collisions, but also facilitate the driver to lift it when the snowmobile encounters driving obstacles. Therefore, the tilting angles of the front anti-collision beam 112 and the rear anti-collision beam 113 can be preferably 30° to 45° according to ergonomics.

[0135] One of the embodiments of the present application is as follows: Fig.12 and Fig.13 As shown, a connecting rib 52 is fixedly provided on the upper end surface of the sled 5 , and the sled 5 can be hinged to the connecting assembly 7 through the connecting rib 52 .

[0136] It is understandable that the overall structural strength of the sled 5 can be increased by providing the connecting ribs 52, and the bolt hole processing can be facilitated by connecting the connecting ribs 52 to the connecting assembly 7. The number of the connecting ribs 52 is at least one, preferably two, and the two connecting members 52 are symmetrically arranged.

[0137] In this embodiment, Fig.12 and Fig.13 As shown, the front part of the sled board 5 is a flexible first snow blocking part 51, and the first snow blocking part 51 is tilted. When the snowmobile is running, the snow in front of the sled board 5 can be compacted by tilting the first snow blocking part 51, thereby ensuring the normal running of the snowmobile.

[0138] It is understandable that, due to the gravity of the snowmobile, the height of the snow in front of the sled board 5 is always above the sled board 5. Therefore, during the driving of the snowmobile, the snow in front of the sled board 5 can be compacted to the bottom of the sled board 5 by the tilted first snow blocking portion 51, thereby ensuring the stability of the driving of the snowmobile. At the same time, the tilting of the first snow blocking portion 51 can also prevent obstacles from directly impacting the sled board 5. Preferably, the tilting angle of the first snow blocking portion 51 is 20° to 45°.

[0139] In this embodiment, Fig.13 As shown, the first snow blocking portion 51 is inclined at both sides, that is, the first snow blocking portion 51 is narrower as it is closer to the end.

[0140] It is understandable that snow in the snow is easy to clump, so when the snowmobile is running, the tilted first snow blocking portion 51 may cause the clumped snow to slide to both sides in the process of squeezing the snow in front of the sled board 5, thereby reducing the snow in front of the sled board 5, causing the snowmobile to run with a small bump. By tilting the two sides of the first snow blocking portion 51, the first snow blocking portion 51 has a pointed end, and the clumped snow can be broken by the pointed end of the first snow blocking portion 51 during the running of the snowmobile, thereby ensuring that the compacted snow remains flat. Preferably, the tilt angles of the two sides of the first snow blocking portion 51 are 15° to 30°.

[0141] In this embodiment, Fig.12 and Fig.13 As shown, an extension section 511 is provided at the front end of the first snow guard portion 51 , and the extension section 511 can be bent in an arc shape to be close to the connecting rib 52 and fixedly connected, thereby improving the supporting strength of the first snow guard plate 14 .

[0142] It is understandable that, when the snowmobile is traveling, the first snow blocking portion 51 is impacted by the accumulated snow and will continue to tilt upward, thereby increasing the snow blocking area of ​​the first snow blocking portion 51, that is, increasing the traveling resistance of the snowmobile, so that the tilting degree of the first snow blocking portion 51 can be reduced by the extension rod 511. At the same time, when the first snow blocking portion 51 hits an obstacle, the connection of the extension section 511 can reduce the deformation of the first snow blocking portion 51 caused by the impact of the obstacle, thereby improving the structural stability of the sled 5.

[0143] In this embodiment, Fig.12 and Fig.13 As shown, the rear portion of the sled 5 is a second snow guard 52, which is tilted; when a bump occurs, the sled 5 can be supported by the second snow guard 52 and the snow, thereby preventing the sled 5 from being inserted into the snow during a bump.

[0144] It can be understood that when the sled 5 encounters an obstacle and is bumpy, the sled 5 may rise and fall back and forth, and the raised first snow-blocking portion 51 and the raised second snow-blocking portion 52 can ensure that the front and rear sections of the sled 5 will not be inserted into the compacted snow during the rising and falling process.

[0145] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
