Description

Technical Field

[0001] The invention relates to the field of transportation tools, in particular to an open-closed dual-purpose two-wheeled vehicle with a combined protective device and a shock-absorbing body. Background Art

[0002] The existing electric two-wheeled vehicles for 1-2 people have seven advantages: easy parking, no traffic jams, no motor bearing damage, low cost, low pollution, power saving, and long range. They are small and flexible, with excellent performance, and are also the most widely used passenger vehicles. However, there are three major problems that have not been solved so far. First, there are no protective measures, and the safety performance is extremely poor. Among all passenger vehicles, car accidents cause the most deaths. Second, due to the instability of the two wheels, the fully enclosed car cover is easily blown over by the wind. People have tried to install countless types of car covers, but all failed. They cannot protect against wind and rain, heat and cold. Third, driving is easy to get tired. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a new method of "human body positioning" and "vehicle body shock absorption" and a new structure of "quick-install hanging curtain" to solve the three major problems of existing electric two-wheeled vehicles: riding safety, rain and cold protection, and driving fatigue.

Preferably, the present invention is provided with a front box (9) and a seat rear compartment (53) at the front of the vehicle and behind the seat, respectively, and door front pillars (15) and door rear pillars (34) are provided on both sides of the vehicle body. The rear side of the front box (9) is connected to the door front pillar (15), and the front side of the seat rear compartment (53) is connected to the door rear pillar (34). The door front pillars (15) and door rear pillars (34) on both sides of the vehicle body are convenient for installing a left door rolling curtain (23) and a right door rolling curtain (62).

[0007] Preferably, the present invention has a cargo frame shock absorber (6) installed in front of the vehicle head; the cargo frame shock absorber (6) is made of a highly elastic material, and appropriate damping measures are taken to reduce elastic rebound shock.

[0008] Preferably, the roof cover (26) fixed to the shoulder guard plate of the present invention is an umbrella rib mesh structure, the cover surface portion of the roof cover (26) is a mesh structure, a front window (22) is arranged at the front of the roof cover (26), a roof cover rear edge (31) is arranged at the rear of the roof cover (26), and rolling curtain covers (68) are arranged on both sides of the roof cover (26).

[0009] Preferably, a left door rolling curtain (23), a rolling curtain shaft (17), a groove wheel (32), and a rolling curtain pull rope (28) capable of rolling up the left door rolling curtain (23) through the groove wheel (32) are installed below the rolling curtain cover (68) on the left side of the roof cover (26); after the rolling curtain pull rope (28) passes through the roof cover (26), a screw tube hanging ring (33) is installed at its rear end, and then the screw tube hanging ring (33) is hung inside the roof cover (26) after being guided by the pulley (29). On the elbow pin on the side, the left door rolling curtain (23) is composed of a rolling curtain face cloth (19), a curtain bone strip (104), a curtain anti-slipping ball (103) and a rolling curtain lower end plate (21). Both sides of the left door rolling curtain (23) are located in the gap of the rolling curtain gap clamping plate (102). Since the diameter of the curtain anti-slipping ball (103) on the outer side of the rolling curtain gap clamping plate (102) is greater than the height of the gap, the left door rolling curtain (23) will not slip out of the rolling curtain gap clamping plate (102).

[0010] Preferably, the present invention is to horizontally and transversely pass a support wheel swing shaft sleeve (77) through the bottom of the vehicle from the lower part of the driver's seat and fix it on the vehicle body (3), then insert a support wheel swing shaft (76) into the support wheel swing shaft sleeve (77) and protrude at both ends, the total length of the support wheel swing shaft (76) can be adjusted by replacement, and upper shaft end sleeves (74) are respectively installed at both ends of the support wheel swing shaft (76), and the shaft end sleeves (74) are fixed with cotter pins (75), and upper horizontal sleeves (74) are respectively installed vertically on the upper side surfaces of the two shaft end sleeves (74). A U-shaped operating rod (73) is provided, and a pluggable supporting wheel handle (72) is installed at the upper end of each of the two horizontal U-shaped operating rods (73). The supporting wheel arc plate (44) is passed through the horizontal U-shaped groove of the horizontal U-shaped operating rod (73) and fixed to the vehicle body (3).

The swing angle and angle locking of the supporting wheel (45) are controlled by pushing, pulling or inserting and pulling out the supporting wheel handle (72).

[0011] Preferably, the present invention first pushes the roof cover (26) up to a position suitable for getting on and off the vehicle, then sleeves a large cone-shaped slide tube (95) with a smooth inner wall onto the backrest frame oblique block (43) on one side, then installs a small axle pin seat (93) with an axle hole on the large cone-shaped slide tube (95) and the shoulder guard (24) on the same side, then prepares a support rod (51) with the same axle holes at both ends, and then uses two small axle pins (94) to connect the support rod (51) and the two small axle pin seats (93) together, and in addition, a wedge-shaped swing hook (101) with a wedge-shaped hook at one end and an axle hole at the other end is installed. and a swing hook shaft seat (99) having the same shaft hole, connected together with a swing hook shaft (100), and then the swing hook tail (98) is installed, and then the hook tip of the wedge swing hook (101) is facing the cone head groove of the large cone head slide tube (95), and then the swing hook shaft seat (99) is fixed to the backrest frame oblique block (43), and then the shuttle-shaped compression spring seat (96) and the shuttle-shaped compression spring (97) are installed between the swing hook tail (98) and the backrest frame oblique block (43), and the elastic force of the shuttle-shaped compression spring (97) causes the hook tip of the wedge swing hook (101) to be close to the cone head groove of the large cone head slide tube (95).

[0012] Compared with the prior art, the present invention has the following advantages: 1. The telescopic steering rod 36 can be extended and retracted, which is equivalent to the two small arms being able to be extended and retracted, so that the driver can drive with the telescopic steering rod 36 swinging left and right in a posture of hanging arms and convex shoulders, and the shoulder guard 59 has a "convex shoulder" to protect. Therefore, since the telescopic steering rod 36 creates the shoulder guard 59, the combined body protection device 54 can perform combined positioning and combined shock absorption protection on the human body.

[0013] 2. The "telescopic steering rod 36" can make driving by leaning against the backrest possible, making driving comfortable and less tiring, and also giving a distinct "pushing back feeling", making driving a two-wheeled vehicle more fun and a kind of enjoyment. The "telescopic steering rod 36" has been installed on the "Zhonghualong" brand two-wheeled vehicle I use.

[0014] 3. It is a big problem to position and lock the human body in a moderately loose and tight manner, and to make it "easy to lock and fast to unlock". The "shoulder guard ring 59" of the combined protective device can position the human body in a moderately loose manner, and can also swing up and down to cleverly "lock and unlock", and solve the problem of difficulty in getting on and off the ultra-low closed vehicle. The "shoulder guard ring 59" swinging up and down can also make the "flat bar shock-absorbing body 18" very fast to put on and take off, and can also reduce shock to the human body through the "flat bar shock-absorbing body 18" and the soft cushion shock-absorbing body 55. The multifunctional shoulder guard ring 59 is a major innovation in the safety structure of two-wheeled vehicles.

[0015] 4. The "flat strip shock absorber 18" of the shoulder guard 59 of the "combined body protection device" can effectively alleviate the strong shock of a frontal collision and effectively position the human body in front and back. The existing car "seat belt" is inconvenient to wear and take off, and requires an alarm to enforce it. The "seat belt" also needs to be tightened urgently after the signal is transmitted, and often fails because of "no time to tighten". The "flat strip shock absorber 18" does not need to be tightened, the error rate is 0, and it can be quickly put on and taken off with the up and down swing.

[0016] 5. The driver who operates the telescopic steering rod 36 by “hanging arm and convex shoulder” is surrounded by the shoulder guard, “flat bar shock absorber 18” and backrest board 35. The first big shock of the front collision is alleviated by the “flat bar shock absorber 18”. When the overturned car hits the second time, the driver lies on his side, with his waist restrained by the waist belt 47, his legs supported by the leg partition board 6, and his shoulders supported by the shoulder guard ring 59. With the protection of other shock absorbers, he is not injured and does not fall on the road for a second time. This is the beneficial effect of the “combined body protection device” in “combined human body positioning” and “combined vehicle body shock absorption”.

[0017] 6. Two-wheeled electric vehicles are safe to drive and can protect against wind and rain. In terms of the number of passengers, the occupancy rate of five-seater cars is extremely low, and most of them only carry one or two people. In addition, two-wheeled vehicles have many advantages such as being small, light and flexible. Two-wheeled electric vehicles will inevitably replace most cars and become the mainstream of family passenger cars. This will make a great contribution to alleviating urban traffic jams, alleviating parking difficulties and urban development.

[0018] 7. As mentioned above, the electric two-wheeled vehicles of this project will replace most cars. Due to the huge number of cars replaced, driving energy saving will be great, and the materials and equipment configuration of the vehicle will be saved several times, which will make a great contribution to carbon emissions and reducing haze. In addition, as long as the shoulder guards or curtains of each electric two-wheeled vehicle use a small amount of carbon fiber and 3D printing, it will drive the development of many industries in society and produce great social benefits.

[0019] 8. The light roof cover 26 and the cloth curtain are extremely light and easy to assemble and disassemble. In particular, the light weight of the roof can effectively reduce the center of gravity of the whole vehicle. In addition, the wide wheelbase support wheels 45 can be used to "fully enclose the vehicle" even in heavy wind and rain, just like the existing "tricycle for the disabled". Moreover, the roof cover 26 and the cloth curtain of the umbrella rib mesh are not easy to be damaged because they are protected by the shock-absorbing airbag 79. "Fully enclosed driving" is a major innovation in bicycles over the past century.

[0020] 9. The benefits of open-top vehicles over closed-top vehicles are lower wind resistance, more power saving, lower center of gravity, and safety. Since heavy rain with curtains hanging accounts for about one-quarter of the days, driving open-top vehicles with curtains removed can extend the life of the curtains by three times, greatly reducing costs and improving safety performance.

DETAILED DESCRIPTION

[0022] In order to make the purpose, principle and structure of the present invention more clear, it is further described below in conjunction with the drawings and specific embodiments.

[0023] Embodiment 1 The present invention provides an open-closed dual-purpose two-wheeled vehicle with a combined protective device and a shock-absorbing body, comprising a vehicle body, wheels, a front fork, a driver's seat, and a waist belt. The vehicle body (3) is characterized in that a backrest frame (39) is installed on the vehicle body (3) behind the driver's seat (48), and the backrest frame (39) is provided with a backrest frame vertical gear (71), a backrest frame upper gear (70), a backrest frame oblique gear (43), and a backrest board (35). A shoulder guard ring swing shaft (66) and a shoulder guard ring swing shaft sleeve (67) are installed on the backrest frame upper gear (70), and a left shoulder guard plate (24) and a right shoulder guard plate (25) are installed on the backrest frame (39) in a horizontally forward extending shape through the shoulder guard ring swing shaft (66) and the shoulder guard ring swing shaft sleeve (67), and the horizontal forward extending shape is made to extend forward. The height of the extended left and right shoulder guards reaches the shoulder position of the person on the driving seat (48), and then the two ends of an elastic flat bar shock absorber (18) are installed at the front position of the left shoulder guard (24) and the right shoulder guard (25), and a cushion shock absorber (55) is also provided on the left and right shoulder guards. In this way, the left shoulder guard (24), the right shoulder guard (25), the flat bar shock absorber (18), and the cushion shock absorber (55) form a horizontal U-shaped shoulder guard ring (59). Since the existing two-wheeled vehicle driver extends his arms to operate the "ox horn handle" to drive, the shoulder guard ring (59) has no shoulders to protect, and a telescopic steering rod (36) needs to be provided. The structure of the telescopic steering rod (36) is as follows: A steering sleeve (10) having a screw hole in the diameter direction is fixed horizontally and longitudinally on the upper end of the front fork (4). Then, a steering rod (11) whose outer circle matches the inner hole of the steering sleeve (10) is inserted into the steering sleeve (10). The steering rod (11) is provided with a longitudinal long groove. Then, a rotation-stopping screw (8) is screwed into the screw hole of the steering sleeve (10) and further screwed into the longitudinal long groove of the steering rod (11), so that the steering rod (11) can only slide forward and backward in the steering sleeve (10) but cannot rotate. Then, a speed control handle (12) and a brake handle (13) are installed at the rear end of the steering rod (11) (consistent with the front and rear of the vehicle body). In this way, the steering sleeve (10), the steering rod (11), the stop screw (8) and the steering rod (11) are connected to each other. The turning screw (8), the speed control handle (12), and the brake handle (13) form a telescopic steering rod (36) that allows a person to drive in a vertical arm and shoulder posture. The shoulder guard (59) has a "shoulder" to protect. In addition, a roof cover (26) for "head protection" and rain protection is installed on the upper part of the shoulder guard (59). The roof cover (26) can swing up and down together with the shoulder guard (59) around the center line of the shoulder guard swing shaft (66) on the backrest frame (39). When the shoulder guard (59) and the roof cover (26) swing down together in a horizontal position, the backrest frame (39), the shoulder guard (59), the telescopic steering rod (36), and the roof cover (26) form a "combined body protection device (54)".

[0024] The backrest frame upper gear 70 is tubular, and a combined shock absorbing body 57 is installed at each end of the backrest frame upper gear 70. The combined shock absorbing body 57 (attached Figure 5) is as follows: the airbag ear 81 of the tire airbag 79 is fixed to the airbag tray 80 with a connecting screw 82 and a nut 83, and then one end of the airbag tray handle 84 is fixed to the center of the airbag tray 80, and then the airbag tray handle 84 is inserted into the hole at one end of the backrest frame upper block 70, and a guide long hole 85 is drilled on the airbag tray handle 84, and a guide pin 86 is installed, and then a damping spring assembly 87 is placed in the pipe hole of the backrest frame upper block 70, and the damping spring assembly 87 is tightened with the combined shock-absorbing body 57 at the other end of the backrest frame upper block 70, and then the guide pin 86 at the other end is installed.

[0025] A front shock absorber frame 1 is installed on the vehicle body at the front of the vehicle, and a front shock absorber frame oblique gear 50 and a front shock absorber frame upper gear 61 are arranged on the front shock absorber frame 1. The front shock absorber frame upper gear 61 is tubular, and a combined shock absorber 57 is installed at both ends of the front shock absorber frame upper gear 61. The structure of this combined shock absorber 57 is the same as the combined shock absorber 57 at both ends of the backrest frame upper gear 70. Door front pillars 15 and door rear pillars 34 are arranged on both sides of the vehicle body, the rear side of the head box 10 is connected to the door front pillars 15, and the front side of the seat rear compartment 53 is connected to the door rear pillars 34. The door front pillars 15 and the door rear pillars 34 on both sides of the vehicle body are installed with left door rolling curtains 23 and right door rolling curtains 62.

[0026] The left door rolling curtain 23 on the roof cover 26 above the left door is semi-permanently mounted on the roof cover 26 for sheltering from rain. When the left door rolling curtain 23 needs to be rolled up, the screw tube hanging ring 33 installed on the inner side of the roof cover 26 above the shoulder is pulled to roll up the rolling curtain, and the screw tube hanging ring 33 is hung on the preset elbow pin 46. When the curtain needs to be lowered to avoid rain, the screw tube hanging ring 33 on the lower end plate 21 of the rolling curtain is pressed down by hand to hang the screw tube hanging ring 33 on the elbow pin 46 on the left door sill, and the screw rod and screw tube 20 on the screw tube hanging ring 33 are tightened to make the left door rolling curtain 23 sealed and scraped.

[0027] The right door roller blind 62, the backrest roller blind 36 and the roof roller blind 27 are all composed of roller blind face cloth 19, curtain bone strip 104, anti-drop curtain ball, roller blind upper end plate 63, roller blind lower end plate 21 and screw tube hanging ring 33, except for the difference in size. The method of hanging the roller blind is to hang the hanging hole on the end plate at one end of the roller blind and the screw tube hanging ring 33 at the other end on the elbow pin 46 preset on the curtain hanging door frame, and tighten the screw rod and screw tube 20 on the screw tube hanging ring 33, so that the roller blind face cloth 19 is tightened, sealed and flat, and then the roller blind seam clamp 102 is clamped on the two preset pointed pins 106. When disassembling, the roller blind can be taken off, rolled up and stored in the rear compartment 53 of the vehicle seat. Spring sheets are arranged in the holes at both ends of the rolling blind seam clamping plate 102, so that the rolling blind seam clamping plate 102 can be clamped on the pointed pin 106 quickly and firmly.

[0028] The structure and loading and unloading method of the roof curtain 27 on the roof cover 26 are the same as those of the right door curtain 62. The use of the curtain surface cloth 9 to replace the steel plate commonly used in the vehicle body is an innovative solution that is used out of necessity in view of the characteristics of the two-wheeled vehicle. This can greatly reduce the weight of the vehicle, greatly lower the center of gravity, and is easy to carry. It is easy to close the "open vehicle" and shelter from rain at any time, which is an important means for the two-wheeled vehicle to achieve "full closure". The disadvantage is that the curtain cloth is "easy to damage". Since the "curtain cloth" is relatively easy to damage, and only when the curtain is used on rainy days and the vehicle is scratched and hit, the curtain cloth is damaged. This opportunity is rare, so it is feasible for the two-wheeled vehicle to use the "curtain cloth" to shelter from rain.

[0029] In addition, the present invention is also provided with a wide wheelbase manually operated support wheel for parking and three-wheel driving. When parking, pull out and push back the support wheel handle 72 to a vertical position and then press down to position the support wheel 45, and the vehicle can be parked. When parking, starting the rear wheel motor and driving at a slower speed can prevent the vehicle from being blown over by strong wind. When driving normally, just pull up and push forward any support wheel handle 72 on both sides of the vehicle to make the support wheel 45 to a horizontal position and then press down the support wheel handle 72 to position the support wheel 45, and the vehicle can be driven. This support wheel 45 can be used to perform parking operations, parking operations and three-wheel driving operations while sitting on the driver's seat, and the operation is convenient and getting off the vehicle is stable.

[0030] The support rod 51 of the roof cover 26 (see attached Figure 7 ), which is used to quickly lock the opened roof cover to facilitate getting on and off the vehicle. When the roof cover 26 is pushed up to a position where it touches the roof cover stop pin 52 and the roof cover 26 cannot be pushed, the support rod 51 dragged up by the roof cover 26 also drives the large cone head slide tube 95 to slide up along the backrest frame inclined block 43 to a position where the hook tip of the wedge head swing hook 101 just hooks the cone groove of the large cone head slide tube 95. The opened roof cover is also supported by the support rod 51. The driver can get on the vehicle and sit down. When the swing hook tail 98 is pressed by hand, the wedge swing hook 101 is lifted, the large cone head slide tube 95 is unhooked, and the roof cover 26 loses the support of the support rod 51 and the large cone head slide tube 95, and swings down with the shoulder guard 24 until the shoulder guard connecting stop 16 is supported by the door post fork 14. The driver sitting on the driver's seat is protected by the shoulder guard ring 59 and the roof cover 26, and can drive safely without wind or rain.

[0031] The present invention has three types of vehicles, namely, a fully open vehicle, a semi-open vehicle and a fully enclosed vehicle. The fully open vehicle structure is the entire structure except for the roof cover 26 and four roller blinds (i.e., the left door roller blind 23, the right door roller blind 62, the roof roller blind 27, and the backrest roller blind 36).

[0032] When a fully open vehicle is to be driven, the shoulder guard 24 is pushed up until it cannot be pushed anymore, and then it is supported by the support rod 51. The driver gets on the vehicle and sits down, with his feet on the ground. He presses the swing hook tail 98 with his left hand, and the wedge swing hook 101 is unhooked to make the support rod 51 slide down. He holds the descending shoulder guard 24 with his right hand until the shoulder guard connecting block 16 is supported by the door post fork 14, and the human body is framed by the shoulder guard ring 59. Then he pulls up and pushes the support wheel handle 72 forward with his left hand, so that the support wheel 45 is in a horizontal position and the support wheel handle 72 is inserted into the hole of the support wheel arc plate 44, locking the support wheel 45. Then he unlocks the door and turns on the power, operates the speed control handle 12 and the brake handle 13 to drive the vehicle, and steps on the foot pedal 49 with both feet.

[0033] If the fully open vehicle is to be parked, the vehicle is first parked, and then the supporting wheel handle 72 is pulled out and pushed back to make the supporting wheel 45 reach the supporting position, and then the supporting wheel handle 72 is pressed down to lock the supporting wheel 45, and the key is pulled out to cut off the power. Similarly, the positioning shoulder guard 24 is pushed up, the vehicle is stopped and the vehicle is stationary, and then the swing hook tail 98 is pressed to cover the horizontal position of the shoulder guard 24.

[0034] The driving operation of a semi-open car is the same as that of a fully open car, the only difference is that there is a roof cover fixed on the shoulder plate.

[0035] The fully enclosed vehicle structure is as follows Figure 1 The method is to open the rear door 40 of the semi-open vehicle covered with the roof cover 26, take out the three roller blinds in the rear door 53, hang them on the roof, right door and backrest frame, and put down the roller blind of the left door. It is safe to ride and can protect from wind, rain, cold and heat. The disadvantage is that it consumes more energy and needs to drive slowly on windy days.

[0036] To drive a fully enclosed vehicle, first open the roof cover like an open vehicle, sit down, cover the roof cover, swing the support wheel 45 to a horizontal position, and then operate the speed control handle 12 and the brake handle 13 to drive. When heat preservation and rain protection are required, the lower end plate 21 of the rolling curtain is pressed down, and the screw tube hanging ring 33 on the lower end plate 21 of the rolling curtain is hung on the elbow pin 46 on the door sill. In heavy rain or strong wind, two wheels can be driven. In heavy rain and strong wind, the support wheel 45 needs to be activated at the same time to drive the vehicle at a slow speed.

[0037] If you want to park a fully enclosed vehicle, the operation is the same as that of an open vehicle in non-rainy weather. The only difference is that you need to lower the roller blind in rainy weather. The other operation methods are the same as those of an open vehicle.

[0038] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solutions and novel concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
