At present, there are various types of transportation vehicles on the market that are most assisted by electric wheelchairs. Figure 1. The conventional electric assistance assists the main user of the pestle. See also / Youli wheelchair mainly includes有 一个 车 # i 、 一 嗖 ίο 15 Seat 2 on the frame 1 which can be used by the user 2 Car wood 1 〇 The rear wheels 3 and 2 are installed in the car-set behind the frame 1 and placed in the car plus〗 The driving wheel 4 in the middle of this Shi Lao 1 and the two front guide wheels located at the corner of Soapwood 1 ^ ¥¥ The wheelchair uses the driving wheel 4 and the moon V wheel 5 to ground 100 motorcycles ^ [Fish plus] Mushili contact, while the rear wheel 3 is used as an auxiliary fork to marry the car 1 with an anti-falling action m ... ㈣ Use 'the frame 1 has an electric horse 6 Wu drive wheel 4 for connection value private pull The driving force generated by the operation of the driving wheel 4 can move the entire wheelchair to travel. —Wheelchairs are in the process of being transported. They usually reach various undulating facial limb roads. In order to pass obstacles smoothly, the industry usually designes a front guide wheel group 10 mechanism that cooperates with the guide wheels 5 as a way to overcome obstacles. Yong Yan, referring to FIG. 2 at the same time, the conventional front wheel set 10 includes a guide wheel set u with two teeth set on the guide wheel set n; 2, an adjustment nut screwed to the lower end of the positioning bolt M 13, and a plurality of rubber rings set on the positioning bolt 12 to resist the guide _ wood 11 as a cushioning rubber ring 14 ′ The guide wheel frame I! The rear end is equipped with a car, and 1] can be connected to the car An insert seat at the front of the frame 1 enables the entire guide wheel frame 11 to have the ability to move up and down. The front wheel 20 of the guide wheel frame 11 has a M257804 end which extends downwards and can be used for the front guide wheel 5 as a shaft connection. The guide wheel frame 11 has a positioning hole 113 at the upper edge near the rear end, and a positioning bar 114 is provided at the lower edge corresponding to the positioning hole 113. In contrast, a bottom hole 1G2 is also provided at the bottom side of the insertion seat. The record 12 penetrates from the positioning hole in of the guide wheel frame ^ and extends into the positioning bar hole 114, and then passes through the pivot seat ιιιι holes ι〇2 (Iv) Finally, spiro towel stomach 13-bit slave difficult lower pin 12, thereby positioning the subject 12 has upper and lower ends are formed from end portions can stop the guide wheel frame 11 is swung. Referring again to the figure, in the case where the current guide wheel 5 encounters a raised road surface, by driving the driving force of the driving wheel 4, the front guide wheel 5 can roll across the elevated road surface 200, and the guide wheel frame 11 can adapt to the terrain slope. The size of the wheel is swung, and then the driving force generated by the friction between the driving wheel 4 and the ground 100 can drive the entire wheelchair through the raised road surface 200. It is known that although the front guide wheel set H) has the ability to overcome obstacles, it has its shortcomings in use. 'That is, when the current guide wheel 5 starts to rise 200 degrees above the road surface', the entire frame 1 will tilt. If the obstacle height of the raised road fan is too high, it will cause the wheelchair to tilt the front guide wheels 5 and rear wheels 3 to support the ground, while the driving wheel 4 that provides power in the middle will instead ...... Under the frictional contact of the ground, it will even cause idling. At this time, it cannot generate enough driving force to make the entire wheelchair smooth. ^ Therefore, it is known that the ability of the front guide wheel group 10 to overcome obstacles is not good. There are restrictions on the use of particularly high obstacle roads. …, [New content] This kind of high-efficiency can overcome obstacles. The purpose of this new type is to provide an action vehicle that can overcome obstacles and can overcome obstacles. 20 M257804 5 10 15 Contains' The new model provides a mobile vehicle that can overcome obstacles, including a charter frame, a body, two suspension devices, and two front guide wheel devices.

Expanding the wall ... ¥ wheel devices each have -shaft connected to the frame pivot axis 早 # 早 凡,-connected to the swing arm The front guide wheel at the lower end of the unit, and the actuating unit at —S and interlocking with the suspension frame. This: The swivel arm unit can be driven across the ground to make a pivot bar with the fulcrum axis as the axis. Press down on the hanger to make contact. The new function of the ground and the ground is mainly to use the lever movement of the rotary arm unit. When the guide wheel encounters a particularly high road surface, the drive wheel can be pressed down to make frictional contact with the ground, thereby driving. Wheels can indeed generate effective driving force, which can easily lead the car body to complete the action of crossing obstacles.

The "2" guide wheels 40 each have a shaft connected to the fulcrum shaft 211 of the frame 21, a net unit * 41, a front guide wheel 42 & connected to the lower end of the arm unit 41, and An actuating unit 43 at the upper end of the arm unit 41 and connected to the suspension frame 。. The swivel arm unit 41 is composed of a main arm plate 4m, a 10 15 20 ^ roller 413, a wheel seat plate 414, and a locking element Group 415, 'the main arm plate 411 and the support plate 412 are arranged parallel to each other at the front of the frame 21', the space formed between the two can just avoid the rod tube of the drive frame M, and the lower end of the support plate 4U is combined with the main arm Itagawa, and the main arm plate 4m and the support of the central part of the frame and the fulcrum shaft 211 of the frame 21 to make a connection, so that the entire arm single "i can be pivoted on the fulcrum shaft 211 as a lever, the roller 413 horizontal 1 Knotted at the upper ends of both the main arm plate 411 and the support plate 412, the bottom edge of the main arm plate 411 and the support plate 412 can be in contact with the actuating unit 43. The lower end of the wheel seat plate 414 has a front wheel pivot seat 4i41 for the front guide wheel 42. The central part of the seat plate 414 has a & a rotating shaft 4142 which is connected to the lower end of the main arm plate 411 so that the wheel seat plate can be pivoted to adjust its angle. The upper part of the wheel seat plate 414 is provided with an arc-shaped groove 4143 near the shaft. The locking element 415 can be penetrated by the arc-shaped groove 4143 and screwed with the main arm plate 4U. 'Rotating the handle 4151 can quickly make the wheel seat plate 414 and the main arm plate 4m in a clamped or loose state. The operating unit 43 1 and a handle 431 and a set of „431 Actuator 4; 2 have 10 M257804: Male has a flat plate 4311 can accept the cantilever unit "Roller 4 clear end through the long perforation of the suspension bracket 31 fixed plate 312 slide down, the actuation spring * 432 The upper and lower ends are respectively resilient against the 5 10 15 20 plus the fixing plate 312, which can elastically support the support rod 431 and have a downward elastic force on the core suspension cymbal 31. The above is the new type that can overcome obstacles An overview of the associated structure and location of the main location of the mobile vehicle; then, the use of the new model and the expected effect can be stated as follows: See Figure 7 'The new model 2G body is guided by the front wheels 42. The driving wheel% and the rear wheel 24 are in contact with the ground support and are located in the middle position. The moving wheel ^ is the source of power. It is fixedly mounted on the suspension 31 to drive the entire vehicle body 20 to move, while the front guide wheel 42 and the rear wheel 24 are steerable, and 4 is used to control the vehicle body 20 When traveling, whether it is the material wheel 42 or the rear wheel 24, the distance between the two and the driving wheel 35 is short, so the turning radius of the new body is relatively small, which can flexibly manipulate and change the direction of travel. See Figure 8 '' When the new vehicle body 20 passes a general obstacle, the front guide wheel 42 will first make contact with the raised road surface. When the obstacle height (D1) of the raised road surface 2 is not large, the front guide wheel 42 rises and rises. 20 pavement. _ Later, the upper roller 413 of the cantilever unit 41 will push down the actuating unit 43, but only let the actuating spring 432 slightly press down. The suspension 31 can remain stationary, and the driving wheel 35 is in normal contact with the ground 100. 'With the driving force generated by the driving wheels 35, the entire vehicle body 20 can be smoothly driven across the raised road surface 200. Refer to Figure 9—'When the new carcass-times do not rise. When the obstacle rises, the front guide wheel 42 will first roll across the uplift road 300, across the uplift 11 M257804 road surface 300 if the drive wheel 35 is blocked When the space is suspended, the roller 413 at the upper end of the arm unit 41 will further press the actuating unit 43. The actuating leaflet 432 is compressed and then the spring 3i is pressed downward. The suspension 31 together with the driving wheel 35 will swing downward with the fulcrum axis 211 as the center. In this way, the driving wheel 35 will come into frictional contact with the ground after moving down, so it will not appear overhanging, and the driving wheel 35 can generate sufficient driving force. The entire vehicle body 20 is driven to cross a high raised road surface 300. 10 15 20 As shown in Figure 10, the new model can moderately adjust the height of the front-guide wheel 42 in order to achieve a smooth crossing in response to special obstacle roads, that is, the current guide wheel 42 encounters an obstacle road with a high obstacle height (D2). At 400 hours, because the center height of the front guide wheel 42 is lower than the obstacle road surface, the front guide wheel 42 cannot roll smoothly. 'At this time, the user can first turn and loosen the locking element 415, and then adjust the elevation angle of the wheel seat plate 414. After the center height of the front guide wheel 42 is higher than the obstacle road surface, the locking element 415 is locked, so that the front guide wheel 42 can smoothly cross the painted obstacle road 400 to complete the spanning action. — 、 + Research double can overcome obstacles. The action vehicle is mainly used to solve the problem of lack of ability to cross the vehicle. The method used in this new model is beneficial: a suspension device with a movable swing is set at the bottom of the frame 21. 30. This suspension garment is equipped with 30% power output unit and driving wheel π. The front of frame u is pivotally connected with a swing arm unit that can perform core rod movement ^. The lower end of the swing arm unit 0 is provided with a front guide wheel 42. And the upper end is linked with the suspension device 30. In this way, when the 'guide wheel 42 crosses the road surface of the upper condyles, the suspension device 3 is also driven. : Press to make the driving wheel 35 ^ move closer to the ground 100 deep A. By driving, the driving force can generate an effective driving force to drive the car body 20 to overcome obstacles, which can be solved. 12 M257804 Knowing the friction between the driving wheel and the ground Insufficient spanning ability caused by the problem 'Therefore, this new model does have the effectiveness of Tetezaki's ship power. 5 10 15 20 But the above is only one of the preferred embodiments of this new model.
