Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0048] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0049] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0050] See also Figure 1 An embodiment of the present application provides an uphill and downhill mobile vehicle, including a vehicle body 4 and an auxiliary support mechanism 1, a wheel 41 is connected to the bottom of the vehicle body 4, the auxiliary support mechanism 1 is connected to the vehicle body 4, and is used to abut against the slope to support the vehicle body 4.

[0051] It should be noted that the vehicle body 4 is provided with a loading space for carrying people or goods, and the uphill and downhill mobile vehicle also includes a motor for driving the wheels 41 to move forward; the number of wheels 41 is set according to demand, for example, the vehicle body 4 can be connected to a wheel 41 to form a unicycle; it can also be connected to a wheel 41 at its opposite ends to form a two-wheeled vehicle, or a three-wheeled or four-wheeled vehicle. The present application does not limit the number of wheels 41.

[0052] In actual applications, the auxiliary support mechanism 1 can be fixedly connected to the vehicle body 4 or movably connected; preferably, the auxiliary support mechanism 1 is movably connected to the vehicle body 4. Specifically, the auxiliary support mechanism 1 can rotate around the vehicle body 4. When the vehicle body 4 climbs a slope, the vehicle body 4 is prone to tipping over due to the change in the center of gravity. The auxiliary support mechanism 1 is rotated along the vehicle body 4 to make it abut against the slope. The auxiliary support mechanism 1 has a certain length and can abut against the slope. Through the abutment between the auxiliary support mechanism 1 and the slope, the auxiliary support mechanism 1 provides a supporting force to the vehicle body 4 to prevent the vehicle body 4 from tipping over, maintain the balance of the vehicle body 4, and enable it to climb the slope smoothly.

[0053] It is understandable that when the auxiliary support mechanism 1 is fixedly connected to the vehicle body 4, it can also play the above-mentioned auxiliary support role; preferably, other active connection methods such as sliding can be adopted between the auxiliary support mechanism 1 and the vehicle body 4, and this application does not limit this.

[0054] It should be noted that slope refers to scenes such as multiple steps, slopes with an inclined angle, or walking surfaces with raised or concave obstacles, which require transportation equipment to climb or overcome obstacles; climbing includes both uphill and downhill movements.

[0055] Preferably, when the auxiliary support mechanism 1 is rotationally connected to the vehicle body 4, the auxiliary support mechanism 1 can be driven to rotate by a motor. During the process of the vehicle body 4 climbing the slope, the motor drives the auxiliary support mechanism 1 to rotate to adjust the angle between the auxiliary support mechanism 1 and the slope surface as the vehicle body 4 tilts, so that it abuts against the slope surface more stably. The auxiliary support mechanism 1 and the vehicle body 4 can also be manually driven to rotate, which can also play the above role, and this application does not limit this.

[0056] See also Figure 2 In one of the embodiments, the auxiliary support mechanism 1 can rotate relative to the vehicle body 4 in multiple planes. Specifically, a rotating member 3 that can rotate along the vehicle body 4 is connected to the top of the vehicle body 4, and the auxiliary support mechanism 1 is rotatably connected to the rotating member 3.

[0057] In this way, through the rotation of the rotating part 3, the auxiliary support mechanism 1 can be rotated along multiple planes relative to the vehicle body 4. This arrangement can change the relative position of the auxiliary support mechanism 1 and the vehicle body 4. Specifically, along the moving direction of the vehicle body 4, the auxiliary support mechanism 1 can be located at any position such as the front, rear or side of the vehicle body 4; in actual application, when the vehicle body 4 is climbing a slope, the direction in which the vehicle body 4 is likely to tip over is judged based on the inclination angle between the vehicle body 4 and the slope, and the auxiliary support mechanism 1 is rotated to a preset position along this direction to abut against the slope, so as to provide support force to the vehicle body 4 and prevent the vehicle body 4 from falling.

[0058] It should be noted that the above-mentioned front and rear positional relationship is based on the moving direction of the vehicle body 4 , the direction consistent with the moving direction of the vehicle body 4 is the front, and the direction opposite to the moving direction of the vehicle body 4 is the rear.

[0059] See also Figure 3 In one embodiment, the auxiliary support mechanism 1 includes a fixing member 11, which is connected to the vehicle body 4 and is used to abut against the slope. The abutment between the fixing member 11 and the slope provides support force to the vehicle body 4 to prevent the vehicle body 4 from becoming unstable and tipping over. The structure is simple and production costs are saved.

[0060] It is understandable that the connection between the fixing member 11 and the vehicle body 4 may be a fixed connection or a movable connection, and the present application does not limit this.

[0061] It should be noted that there are two situations in which the fixing member 11 abuts against the slope. One is that the fixing member 11 directly abuts against the slope to play an auxiliary supporting function, and the fixing member 11 plays an abutting role; the other is that the fixing member 11 serves as a connecting member, and other forms of abutting members are arranged on the fixing member 11, and the abutting member abuts against the slope to play an auxiliary supporting function. In this case, the fixing member 11 plays a connecting role. The above two situations are within the protection scope of this application.

[0062] See also Figure 4 In one embodiment, the auxiliary support mechanism 1 further includes a plurality of first abutment wheels 14, and the plurality of first abutment wheels 14 are sequentially arranged on the fixing member 11;

[0063] Preferably, multiple first abutment wheels 14 are respectively connected to opposite sides of the fixing member 11; in actual application, the first abutment wheels 14 extend from the fixing member 11 in a direction close to the slope, and when the fixing member 11 abuts against the slope, the first abutment wheels 14 abut against the slope first, and the friction between the auxiliary support mechanism 1 and the slope is reduced by the first abutment wheels 14, thereby preventing the auxiliary support mechanism 1 from hindering the movement of the vehicle body 4.

[0064] It should be noted that the sizes of the plurality of first abutment wheels 14 may be consistent or inconsistent, and preferably the first abutment wheels 14 are consistent in size; the plurality of first abutment wheels 14 may be arranged in one row or multiple rows on the fixing member 11, and this application does not limit this.

[0065] See again Figure 4 In one embodiment, the auxiliary support mechanism 1 also includes a second abutment wheel 15, which is connected to the end of the fixing member 11 away from the vehicle body 4, and is used to abut against the slope. The diameter of the second abutment wheel 15 is larger than that of the first abutment wheel 14; the second abutment wheel 15 is arranged at the end of the fixing member 11, which increases the abutment area between the fixing member 11 and the slope, making the abutment between the fixing member 11 and the slope more stable.

[0066] Preferably, the second abutment wheel 15 can be an omnidirectional wheel, a common wheel or a Meckenna mother wheel, which together with the wheel 41 of the vehicle body 4 constitute a multi-wheel vehicle.

[0067] It is understandable that the first abutment wheel 14 and the second abutment wheel 15 can be simultaneously provided on the fixing member 11, or one of the first abutment wheel 14 and the second abutment wheel 15 can be provided. A plurality of first abutment wheels 14 can be provided in one row or in multiple rows on the fixing member 11, and the number of the second abutment wheels 15 can be provided according to actual needs, and the present application does not impose any limitation on this.

[0068] See also Figure 5 In one embodiment, the auxiliary support mechanism 1 further includes a track 16 or a chain, and a plurality of support wheels 19. The fixing member 11 is provided with a plurality of support wheels 19. The track 16 or the chain is sleeved on the outer periphery of the support wheel 19. The support wheel 19 is used to abut against the slope through the track 16 or the chain. The track 16 and the support wheel 19 form a track wheel, and the chain and the support wheel 19 form a chain wheel. By providing the track wheel or the chain wheel, on the one hand, the friction with the slope is reduced, and on the other hand, the contact area with the slope can be increased to make the abutment more stable. Preferably, the plurality of support wheels 19 are respectively connected to the opposite sides of the fixing member 11.

[0069] It should be noted that the support wheel 19 can be a structure such as a wheel or a bearing.

[0070] It is understandable that the track wheels or chain wheels can be arranged in one row or multiple rows on the fixing member 11, and the present application does not limit this.

[0071] See also Figure 6 In one embodiment, the auxiliary support mechanism 1 further includes an abutment member 12, which is movably connected to the fixing member 11 and can move in a direction approaching or away from the fixing member 11, and the abutment member 12 is used to abut against the slope.

[0072] In actual application, when the vehicle body 4 is climbing a slope, the abutment member 12 abuts against the slope. Since the abutment member 12 can move toward or away from the fixing member 11, the abutment length and abutment area between the abutment member 12 and the slope can be adjusted, so that it can adapt to more different types of obstacles such as steps. For example, obstacles with wider or narrower step surfaces can be adjusted by adjusting the extended length of the abutment member 12 so that the abutment member 12 can better abut against steps of different widths.

[0073] See also Figure 7 , Figure 8 and Fig. 9 Optionally, the abutment 12 may be provided with one or two of a first abutment wheel 14, a second abutment wheel 15, a track wheel or a chain wheel, and the setting method is similar to the above-mentioned fixing member 11; preferably, the abutment 12 is provided with a plurality of first abutment wheels 14 or support wheels 19 in sequence along its length direction, a second abutment wheel 15 is provided at one end of the abutment 12 away from the fixing member 11, and a track 16 or a chain is sleeved on the outer periphery of the support wheel 19 to form a track wheel or a chain.

[0074] It is understandable that the first abutment wheels 14, track wheels and chain wheels can be arranged in one row or multiple rows on the fixing member or the abutment member, and the number of the second abutment wheels 15 can be set according to actual needs, and the present application does not limit this.

[0075] See also Fig.10 The auxiliary support mechanism 1 also includes a first power member 13, which is arranged on the fixing member 11. The driving end of the first power member 13 is connected to the abutment member 12 to drive the abutment member 12 to approach or move away from the fixing member 11 to adjust the abutment length between the abutment member 12 and the slope.

[0076] It should be noted that if Fig.10 As shown, the first power member 13 may be provided in one, two, three or more forms to strengthen the abutting force between the abutting member 12 and the slope surface. The present application does not limit the number of the first power members 13 .

[0077] See also Fig.11 and Fig.12The auxiliary support mechanism 1 also includes a connecting member 18 and a second power member 17. The connecting member 18 is slidably connected to the fixing member 11. The driving end of the first power member 13 is connected to the connecting member 18. The second power member 17 is respectively connected to the connecting member 18 and the abutment member 12, and is used to drive the abutment member 12 to move closer to or away from the connecting member 18.

[0078] In actual application, the first power member 13 drives the connecting member 18 to move along the length direction of the fixing member 11, and the connecting member 18 drives the abutting member 12 to approach or move away from the fixing member 11 to adjust the abutment length or abutment area between the abutment member 12 and the slope. The second power member 17 drives the abutment member 12 to approach or move away from the connecting member 18. Preferably, the second power member 17 can drive the abutment member 12 to move along the height direction of the connecting member 18 to adjust the distance between the abutment member 12 and the slope in the height direction, so that the abutment member 12 can approach or move away from the slope in the height direction. With this arrangement, the abutment position of the abutment member 12 and the slope can be adjusted more flexibly as the vehicle body 4 moves.

[0079] Preferably, the first power member 13 can be an electric telescopic rod, and the second power member 17 can be a cylinder or a connecting rod mechanism. The first power member 13 and the second power member 17 preferably have different adjustment directions to adjust the contact angle between the contact member 12 and the slope from multiple directions; if the second power member 17 adopts a connecting rod mechanism, refer to Fig.11 There are two connecting rods rotatably connected between the connecting member 18 and the abutment 12, preferably two parallel connecting rods of the same length. The rotating connection points of the two connecting rods and the connecting member 18 and the abutment 12 form a quadrilateral. The synchronous swinging of the two connecting rods can drive the abutment 12 to move closer to or away from the connecting member 18.

[0080] It should be noted that, as an alternative embodiment, the auxiliary support mechanism 1 may include a fixing member 11, a second power member 17 and an abutment member 12, wherein the second power member 17 is connected to the fixing member 11 and is used to drive the abutment member 12 to approach or move away from the fixing member 11, thereby making the abutment member 12 approach or move away from the slope surface, so as to achieve the abutment effect between the abutment member 12 and the slope surface, and the abutment angle between the abutment member 12 and the slope surface can be adjusted. The second power member 17 may adopt the above-mentioned cylinder or connecting rod mechanism.

[0081] See again Figure 6 The uphill and downhill moving vehicle also includes a climbing mechanism 2, which includes a driving shaft 21, a driving motor 22 and a climbing claw 23. The climbing claw 23 is connected to the driving shaft 21, and the climbing claw 23 extends from the wheel 41 in the radial direction of the wheel 41. The driving shaft 21 is connected to the output end of the driving motor 22 and is rotationally connected to the vehicle body 4. The driving motor 22 is connected to the vehicle body 4.

[0082] In actual application, along the radial direction of the wheel 41, one end of the climbing claw 23 extends to the outside of the wheel 41. Taking climbing multiple steps as an example, the wheel 41 first moves to the first step. At this time, the drive motor 22 starts to operate, driving the drive shaft 21 to rotate, and the drive shaft 21 drives the climbing claw 23 to rotate. Since the climbing claw 23 extends to the outside of the wheel 41, the climbing claw 23 abuts against the first slope surface, and the climbing claw 23 continues to rotate against the slope surface. Due to the friction between the climbing claw 23 and the slope surface, the climbing claw 23 rotates with the slope surface as a fulcrum, so that the end of the climbing claw 23 connected to the drive shaft 21 is lifted, and then the vehicle body 4 is lifted to the top surface of the first step. At this time, the climbing of the first step is completed. Similarly, the climbing claw 23 continues to rotate to complete the climbing of multiple steps.

[0083] It can be understood that when the vehicle body 4 goes downhill, the working principle of the climbing claw 23 is similar to that of climbing. When going downhill, the climbing claw 23 is rotated to make it abut against the first step, and the climbing claw 23 continues to be rotated. Through the abutment force between the climbing claw 23 and the first step, the end of the climbing claw 23 connected to the drive shaft 21 is lifted, and then the vehicle body 4 is lifted to the top surface of the first step. At this time, the climbing claw 23 continues to rotate and flips toward the second step until the wheel 41 drops to the second step. At this point, the first step is completed to the second step. Similarly, the climbing claw 23 continues to rotate to complete the downward movement of multiple steps.

[0084] It should be noted that the movements of the climbing claw 23, the wheel 41 and the auxiliary support mechanism 1 are independent of each other and are driven by three different driving members 24 respectively; the rotation centers of the climbing claw 23, the wheel 41 and the auxiliary support mechanism 1 can be coaxial or eccentric.

[0085] The number of the climbing claws 23 may be one or more; preferably, the plurality of climbing claws 23 are respectively connected to opposite ends of the drive shaft 21 to make the vehicle body 4 more stable when climbing a slope. The present application does not limit the number of the climbing claws 23.

[0086] See also Fig.13 and Fig.14 The climbing claw 23 includes a connecting end 231 and at least one free end 232 , wherein the connecting end 231 is connected to the driving shaft 21 , and the at least one free end 232 is circumferentially connected to the connecting end 231 , and the free end 232 is used to abut against the slope surface.

[0087] In actual applications, one free end 232 or multiple free ends 232 can be set on the connecting end 231. When one free end 232 is set, the production cost can be effectively saved; when multiple free ends 232 are set, the multiple free ends 232 are circumferentially arranged along the connecting end 231. When the driving shaft 21 rotates one circle, multiple free ends 232 can be in contact with the slope in turn. When traveling the same distance, the number of rotations of the driving motor 22 is effectively reduced, thereby extending the service life.

[0088] It is understandable that the present application does not limit the number of free ends 232 and it is set according to actual needs.

[0089] See also Fig.15 The climbing mechanism 2 includes a driving member 24 and a climbing claw frame 25. The length of the climbing claw 23 extending radially in the wheel 41 is adjustable. The climbing claw frame 25 is connected to the driving shaft 21. The climbing claw 23 and the climbing claw frame 25 are slidably connected. The driving member 24 is connected to the climbing claw 23 and is used to drive the climbing claw 23 to move closer to or away from the climbing claw frame 25.

[0090] Specifically, the driving member 24 drives the climbing claw 23 to approach or move away from the climbing claw frame 25 along the length direction of the climbing claw frame 25, so that the climbing claw 23 extends or retracts to the wheel 41. In this way, when the climbing claw 23 is not needed, the climbing claw 23 can be retracted to the wheel 41, reducing the size of the device, making the wheel 41 more delicate and beautiful, and preventing the climbing claw 23 from affecting the normal driving of the wheel 41. When the climbing claw 23 is needed, the driving member 24 drives the climbing claw 23 to extend out of the wheel 41 to abut against the slope surface. Preferably, the extension length of the climbing claw 23 should be adapted to the step height and step length, and the climbing claw 23 and the wheel 41 cooperate with each other to land and play an alternating supporting role. At the same time, since the length of the climbing claw 23 extending out of the wheel 41 is adjustable, the uphill and downhill moving vehicle can be applied to various types of steps or ramps. For example, for steps with a higher height, the extension length of the climbing claw 23 can be adjusted so that it can abut against the step surface, thereby increasing the practicality of the device.

[0091] See again Fig.15 Preferably, the above-mentioned driving member 24 may include a cam 241, a rack 242 and a gear 243. The cam 241 is rotatably connected to the driving shaft 21, the rack 242 is slidably connected to the climbing claw frame 25 and abuts against the outer surface of the cam 241, the gear 243 is connected to the climbing claw 23 and rotatably connected to the climbing claw frame 25, and the rack 242 is meshed with the gear 243.

[0092] It should be noted that the cam 241 is a disc-shaped component that rotates around a fixed axis and has a variable diameter. The rotation of the cam 241 drives the rack 242 to slide along the length direction of the climbing claw frame 25, and the rack 242 drives the gear 243 to rotate, thereby driving the climbing claw 23 to rotate, so as to realize the function of extending or retracting the climbing claw 23 along the radial direction of the wheel 41. In this way, the extension length of the climbing claw 23 can be flexibly adjusted.

[0093] See also Fig.16 As an alternative embodiment, the driving member 24 may include a cam 241, a slide bar 244 and an elastic member (not shown in the figure), the cam 241 is rotatably connected to the driving shaft 21, the slide bar 244 is slidably connected to the climbing claw frame 25 and abuts against the outer surface of the cam 241, and the climbing claw 23 has a first part and a second part connected at an angle, wherein the first part is rotatably connected to the slide bar 244 and the climbing claw frame 25 respectively. The cam 241 rotates to drive the slide bar 244 to extend outward along the length direction of the climbing claw frame 25, the elastic member is elastically connected to the slide bar 244, and is used to drive the slide bar 244 to retract along the length direction of the climbing claw frame 25, and further, the slide bar 244 drives the climbing claw 23 to rotate, so as to realize the function of extending or retracting the climbing claw 23 along the radial direction of the wheel 41. With such a configuration, the structure is relatively simple and the design is more convenient.

[0094] See also Fig.17 As an alternative embodiment, the driving member 24 may include a cam groove structure 248, which is rotatably connected to the driving shaft 21, and a slider 233 is provided at the end of the climbing claw 23, and the slider 233 is slidably connected to the cam groove 2481 of the cam groove structure 248, and the climbing claw 23 is slidably connected to the climbing claw frame 25; the cam groove structure 248 rotates to drive the climbing claw 23 to extend or retract along the length direction of the climbing claw frame 25, so as to realize the function of extending or retracting the climbing claw 23 along the radial direction of the wheel 41. In this way, the slider 233 of the climbing claw 23 is always located in the cam groove 2481, is not easy to fall off, and has high reliability.

[0095] See also Fig.18 As an alternative embodiment, the above-mentioned driving member 24 may include a first bevel gear 245, a second bevel gear 246 and a universal wheel 247, the climbing claw 23 is rotatably connected to the climbing claw frame 25, the first bevel gear 245 is connected to the driving shaft 21 and meshes with the second bevel gear 246, the second bevel gear 246 is rotatably connected to the universal wheel 247, the universal wheel 247 is rotatably connected to the climbing claw 23, and drives the climbing claw 23 to rotate, so that the climbing claw 23 extends and retracts along the length direction of the climbing claw frame 25.

[0096] The first bevel gear 245 is driven to rotate by the driving shaft 21, the first bevel gear 245 drives the second bevel gear 246 to rotate, the second bevel gear 246 drives the universal wheel 247 to rotate, and then drives the climbing claw 23 to rotate around the climbing claw frame 25, so as to realize the function of extending or retracting the climbing claw 23 along the radial direction of the wheel 41. With this arrangement, the movement of the climbing claw 23 is more stable and the adjustment is more flexible.

[0097] It should be noted that the driving member 24 and the climbing claw frame 25 are independently driven by different driving mechanisms.

[0098] It is understandable that in some other embodiments, the above-mentioned driving member 24 can also adopt other methods. For example, the driving member 24 includes a cam 241 and an elastic member. The cam 241 is rotatably connected to the driving shaft 21 and the outer surface abuts against the climbing claw 23. The climbing claw 23 is slidably arranged along the length direction of the climbing claw frame 25. The elastic member is elastically connected to the climbing claw 23. The cam 241 rotates to drive the climbing claw 23 to extend outward along the length direction of the climbing claw frame 25, and the elastic member drives the climbing claw 23 to retract along the length direction of the climbing claw frame 25. The function of the above-mentioned climbing claw 23 extending or retracting radially along the wheel 41 can also be realized. The present application does not limit the specific setting method of the driving member 24.

[0099] See also Fig.19 Optionally, the climbing mechanism 2 may include a rotating wheel 26 and two connecting rods 27, the rotating wheel 26 is connected to the driving shaft, the two connecting rods 27 are rotatably connected to the rotating wheel 26 and the climbing claw 23, respectively, the two connecting rods 27 are preferably arranged in parallel and have equal lengths, the two connecting rods 27 and the climbing claw 23 and the rotating wheel 26 The rotation connection point forms a quadrilateral, preferably the quadrilateral is a parallelogram, the synchronous swing of the two connecting rods 27 can drive the climbing claw 23 to rotate, so as to realize the function of extending or retracting the climbing claw 23 along the radial direction of the wheel 41. In this way, the adjustment flexibility of the climbing claw 23 can be improved through the cooperation between the two connecting rods 27.

[0100] See also Fig. 20 and Fig.21 As an optional embodiment, the climbing mechanism 2 may include a drive shaft 21, a climbing claw support plate 29, a drive motor 22 and an inner wheel 28, the drive motor 22 is connected to the vehicle body 4, the drive shaft 21 is connected to the drive end of the drive motor 22, and is eccentrically connected to the inner wheel 28 to drive the inner wheel 28 to rotate, the climbing claw support plate 29 is connected to the vehicle body 4, and extends from the wheel 41 in the radial direction of the wheel 41.

[0101] In practical applications, the driving motor 22 drives the driving shaft 21 to rotate, the driving shaft 21 drives the inner wheel 28 to rotate, and the inner wheel 28 drives the wheel 41 to rotate. The inner wheel 28 and the wheel 41 are preferably arranged coaxially. Since the driving shaft 21 is eccentrically connected to the inner wheel 28, that is, the rotation point of the inner wheel 28 does not coincide with its axis, the inner wheel 28 has the function of expanding the revolving pair when rotating. When climbing a slope, the climbing claw support plate 29 is used to abut against the slope surface to play a supporting role. When the driving shaft 21 drives the inner wheel 28 to rotate, the eccentric rotation of the inner wheel 28 has a certain lifting effect. With the abutment point between the climbing claw support plate 29 and the slope surface as a fulcrum, the inner wheel 28 can lift itself to the next step surface, and the climbing of one step is completed. Similarly, the inner wheel 28 continues to rotate to complete the climbing of multiple steps. Among them, climbing can include two motion states: uphill and downhill.

[0102] See also Fig. 22 As a preferred embodiment, the auxiliary support mechanism 1 may also be connected to the climbing mechanism 2; preferably, the climbing mechanism 2 is connected to the side of the auxiliary support mechanism 1 away from the vehicle body 4.

[0103] In practical applications, in addition to the climbing mechanism 2 being arranged on the vehicle body 4, the climbing mechanism 2 can also be arranged on the auxiliary support mechanism 1. Specifically, the climbing mechanism 2 is connected to the end of the fixing member 11 away from the vehicle body 4, the driving motor 22 is connected to the fixing member 11, the driving shaft 21 is connected to the output end of the driving motor 22, and the driving shaft 21 is connected to the climbing claw 23. The driving motor 22 drives the driving shaft 21 to rotate, so that the climbing claw 23 on the fixing member 11 abuts against the slope surface, which can play a role in assisting the vehicle body 4 to support the vehicle body 4 on the one hand, and can also provide power for the vehicle body 4 to move forward, assisting the vehicle body 4 to climb the slope, making it easier for the vehicle body 4 to climb the slope, saving time and effort.

[0104] It should be noted that the connection relationship between the auxiliary support mechanism 1, the climbing mechanism 2 and the vehicle body 4 is not limited to the above-mentioned connection relationship. The three can also adopt other connection methods. The connection relationship that meets the auxiliary support and climbing functions is within the scope of protection of this application.

[0105] Different from the prior art, the embodiment of the present application provides an uphill and downhill mobile vehicle, including a vehicle body 4 and an auxiliary support mechanism 1. The bottom of the vehicle body 4 is connected to a wheel 41. The auxiliary support mechanism 1 includes a fixing member 11. The fixing member 11 is connected to the vehicle body 4. The fixing member 11 is used to abut the slope. Compared with the prior art, when the vehicle body 4 climbs a slope, the vehicle body 4 is easy to tip over due to the change of the center of gravity. The auxiliary support mechanism 1 has a certain length and can abut against the slope. Through the abutment between the auxiliary support mechanism 1 and the slope, the auxiliary support mechanism 1 provides a supporting force to the vehicle body 4 to prevent the vehicle body 4 from tipping over, maintain the balance of the vehicle body 4, and enable it to climb the slope smoothly.

[0106] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
