Description

Technical Field

[0001] The utility model belongs to the technical field of automobile shifting structures, in particular to a shifting mechanism for an all-terrain vehicle. Background Art

[0002] All-terrain vehicles are vehicles that can travel on any terrain and can move freely on terrain that is difficult for ordinary vehicles to maneuver. In my country, they are commonly known as beach buggies or farmer's carts. This type of vehicle has wide tires that can increase the contact area with the ground, generate greater friction and reduce the pressure of the vehicle on the ground, making it easy to travel on beaches, riverbeds, forest roads, streams, and harsh desert terrains.

[0003] The gear shift mechanism of an automobile mainly includes the shift linkage, shift lever, shift handle and transmission components. These components and assemblies work together to ensure that the driver can safely and effectively control the vehicle's speed according to road conditions and vehicle speed changes. The mechanical shift mechanism is currently the most commonly used shift mechanism in all-terrain vehicles, and it requires the power of human hands to control the gear position.

[0004] Because all-terrain vehicles often travel on rough roads, the driver is often not able to push the shift handle smoothly when shifting gears like driving an ordinary car, which requires the driver to apply greater force; and the shift handle is easily dislocated due to the bumps of the vehicle. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present utility model is to provide a shift mechanism for an all-terrain vehicle, which is used to solve the problems in the prior art that when the all-terrain vehicle is traveling on a rough road, the driver needs to apply greater force when shifting gears and the shift handle is easily misaligned due to bumps.

[0006] To achieve the above-mentioned purpose and other related purposes, the utility model provides a shift mechanism for an all-terrain vehicle, including a transmission and a shift handle connected by a connecting rod component, a limit plate is provided at the connection between the connecting rod component and the shift handle, a plurality of limit grooves corresponding to different gear positions are formed on the limit plate, and a limit pin matching the limit grooves is provided on the shift handle; the connecting rod component includes a first connecting rod, a second connecting rod and a third connecting rod, the shift handle, the first connecting rod, the second connecting rod, the third connecting rod and the transmission are connected in sequence by a conversion component, and the length of the first connecting rod and the length of the third connecting rod are both smaller than the length of the second connecting rod.

[0007] Optionally, the limiting groove is in the shape of a palm with fingers spread out.

[0008] Optionally, the conversion component includes a plurality of rotatably mounted conversion arms and a plurality of fixedly mounted conversion rods, and the plurality of conversion arms sequentially connect the shift handle, the plurality of connecting rods and the plurality of conversion rods together.

[0009] Optionally, the conversion component includes a first conversion arm, a second conversion arm, a third conversion arm, a fourth conversion arm, a fifth conversion arm, a sixth conversion arm, a first conversion rod and a second conversion rod; the two ends of the first conversion arm are respectively hinged to the bottom end of the shift handle and the upper end of the first connecting rod; the two ends of the second conversion arm are respectively hinged to the lower end of the first connecting rod and the front end of the first conversion rod; the two ends of the third conversion arm are respectively hinged to the rear end of the first conversion rod and the left end of the second connecting rod; the two ends of the fourth conversion arm are respectively hinged to the right end of the second connecting rod and the lower end of the second conversion rod; the two ends of the fifth conversion arm are respectively hinged to the upper end of the second conversion rod and the rear end of the third connecting rod; the two ends of the sixth conversion arm are respectively hinged to the front end of the third connecting rod and the output shaft of the transmission.

[0010] Optionally, the limiting plate, the first conversion rod and the second conversion rod are all fixedly mounted on the vehicle frame.

[0011] Optionally, a dust cover is installed on the shift handle.

[0012] As described above, the shift mechanism of an all-terrain vehicle of the utility model has at least the following beneficial effects:

[0013] 1. The shift mechanism of the all-terrain vehicle is designed with a limit groove and a limit pin that cooperate with each other. When the driver pushes the shift handle, even if the vehicle is traveling on a rough road, the reliability of the shift handle can be guaranteed to avoid the shift handle from being misplaced. At the same time, the shift handle, the first connecting rod, the second connecting rod, the third connecting rod and the transmission are connected in sequence through a conversion component. The length of the first connecting rod and the length of the third connecting rod are both less than the length of the second connecting rod. Therefore, the designer can reduce the thrust when the driver pushes the shift handle by increasing the length of the second connecting rod. Moreover, because the first connecting rod and the third connecting rod are hingedly connected at both ends of the lengthened second connecting rod through the conversion component, compared with the connecting rod component with only two connecting rods in the prior art, the design of lengthening the second connecting rod can still maintain sufficient working strength and working reliability after the length is lengthened.

[0014] 2. The shift mechanism of the all-terrain vehicle is designed with a dust cover installed on the shift handle, which prevents the flying dust from adversely affecting the interior of the shift mechanism when the all-terrain vehicle is traveling on terrain with poor road conditions, thereby reducing the reliability of vehicle driving.

[0019] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0020] See also Figure 1 to Figure 2 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance.

[0021] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0022] See also Figure 1 and Figure 2The utility model provides a shift mechanism for an all-terrain vehicle, comprising a transmission 1 and a shift handle 2 connected by a connecting rod component, a limit plate 4 is arranged at the connection between the connecting rod component and the shift handle 2, a plurality of limit grooves 41 corresponding to different gear positions are opened on the limit plate 4, and a limit pin 21 matched with the limit groove 41 is arranged on the shift handle 2; when the driver pushes the shift handle 2, the reliability of the shift handle 2 can be ensured, even if the vehicle is traveling on a rough road, the shift handle 2 can be prevented from being misplaced, and the problem that the shift handle 2 in the prior art is easily misplaced due to bumps is solved.

[0023] like Figure 1 and Figure 2 As shown, the connecting rod component includes a first connecting rod 31, a second connecting rod 32 and a third connecting rod 33. The shift handle 2, the first connecting rod 31, the second connecting rod 32, the third connecting rod 33 and the transmission 1 are connected in sequence through a conversion component. The length of the first connecting rod 31 and the length of the third connecting rod 33 are both less than the length of the second connecting rod 32. This allows designers to reduce the thrust when the driver pushes the shift handle 2 by increasing the length of the second connecting rod 32. Moreover, because the two ends of the lengthened second connecting rod 32 are hinged with the first connecting rod 31 and the third connecting rod 33 through a conversion component, compared with the connecting rod component with only two connecting rods in the prior art, the design of lengthening the second connecting rod 32 can still maintain sufficient working strength and working reliability after the length is lengthened, thereby reducing the risk of the second connecting rod 32 breaking.

[0024] In another embodiment, see Figure 1 The limit groove 41 is in the shape of a palm with fingers spread out, which is convenient for the driver to quickly operate the shift handle 2 to shift gears.

[0025] In another embodiment, see Figure 1 The conversion component includes a plurality of rotatably mounted conversion arms and a plurality of fixedly mounted conversion rods. The plurality of conversion arms sequentially connect the shift handle 2, the plurality of connecting rods and the plurality of conversion rods together, thereby transmitting the vehicle driving speed that the person wants to obtain by operating the shift handle 2 to the transmission 1; the structure of the connecting rod component and the conversion component is more specifically shown in the next embodiment.

[0026] In another embodiment, see Figure 1 , a specific structural form of a connecting rod component and a conversion component will be introduced, the conversion component includes a first conversion arm 51, a second conversion arm 52, a third conversion arm 53, a fourth conversion arm 54, a fifth conversion arm 55, a sixth conversion arm 56, a first conversion rod 57 and a second conversion rod 58; the specific connection method is:

[0027] like Figure 1As shown, two ends of the first conversion arm 51 are respectively hinged to the bottom end of the shift handle 2 and the upper end of the first connecting rod 31 .

[0028] like Figure 1 As shown, two ends of the second conversion arm 52 are hinged to the lower end of the first connecting rod 31 and the front end of the first conversion rod 57 respectively.

[0029] like Figure 1 As shown, two ends of the third conversion arm 53 are hinged to the rear end of the first conversion rod 57 and the left end of the second connecting rod 32 respectively.

[0030] like Figure 1 As shown, two ends of the fourth conversion arm 54 are hinged to the right end of the second connecting rod 32 and the lower end of the second conversion rod 58 respectively.

[0031] like Figure 1 As shown, two ends of the fifth conversion arm 55 are hinged to the upper end of the second conversion rod 58 and the rear end of the third connecting rod 33 respectively.

[0032] like Figure 1 As shown, two ends of the sixth conversion arm 56 are respectively hinged to the front end of the third connecting rod 33 and the output shaft of the transmission 1 .

[0033] This embodiment describes only a specific structure of the connecting rod component and the conversion component, and designers can also make adaptive adjustments based on the specific layout structure of the vehicle.

[0034] In another embodiment, see Figure 1 The limit plate 4, the first conversion rod 57 and the second conversion rod 58 are all fixedly mounted on the frame to ensure the installation firmness of the entire shifting mechanism.

[0035] In other embodiments, Figure 1 As shown, a dust cover 6 is installed on the shift handle 2, and the dust cover 6 can be a rubber cover. In this embodiment, the dust cover 6 is installed on the shift handle 2 to avoid the flying dust from adversely affecting the interior of the shift mechanism when the all-terrain vehicle is traveling on terrain with poor road conditions, thereby reducing the reliability of vehicle driving.

[0036] To sum up, the utility model is designed to cooperate with the limit groove 41 and the limit pin 21, so that when the driver pushes the shift handle 2, even if the vehicle is traveling on a rough road, the reliability of the shift handle 2 can be ensured to avoid the shift handle 2 from being misplaced; at the same time, the shift handle 2, the first connecting rod 31, the second connecting rod 32, the third connecting rod 33 and the transmission 1 are connected in sequence through the conversion component, and the length of the first connecting rod 31 and the length of the third connecting rod 33 are both less than the length of the second connecting rod 32, so that the designer can reduce the thrust when the driver pushes the shift handle 2 by increasing the length of the second connecting rod 32, and because the two ends of the extended second connecting rod 32 are hinged with the first connecting rod 31 and the third connecting rod 33 through the conversion component, compared with the connecting rod component with only two connecting rods in the prior art, the design of lengthening the second connecting rod 32, the second connecting rod 32 of the shift mechanism of the all-terrain vehicle can still maintain sufficient working strength and working reliability after the length is extended. Therefore, the utility model effectively overcomes the shortcomings of the prior art and has high industrial utilization value.
