The all terrain vehicle disclosed in utility model patent CN219446731U and invention patent CN117301832A has a driving motor and a battery arranged on the vehicle body, and a drive axle assembly transversely across the vehicle body front and rear, which not only results in less space on the vehicle body for installing the battery, only a few batteries can be installed, and the electric endurance is short, at the same time, the drive axle assembly and the vehicle body float synchronously, which makes the all terrain vehicle have a large vibration amplitude, and the drive axle assembly drives the wheels on both sides of the vehicle body to rotate synchronously, which increases the turning radius of the all terrain vehicle, and makes the all terrain vehicle difficult to turn and not flexible. SUMMARY

[0003] The utility model wants to achieve the purpose of providing an all terrain vehicle platform, which solves the problems of poor damping effect, insufficient endurance and difficult turning of the all terrain vehicle in the prior art, improves the endurance of the all terrain vehicle, and improves the damping effect and optimizes the turning effect.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme: an all terrain vehicle platform, comprising a walking system, a vehicle body, a suspension shaft, a battery assembly and an electric control assembly, the walking system is provided with at least two groups and is respectively arranged on the left and right sides of the vehicle body, the battery assembly is arranged on the vehicle body and located between the walking systems on the left and right sides, each group of the walking system comprises a wheel, a drive axle assembly, a driving motor and a damping shock absorber, the driving motor is drivingly connected with the wheel through the drive axle assembly, the electric control assembly controls the speed of the driving motor of each group of the walking system to realize differential steering of the wheels on the left and right sides of the vehicle body, the drive axle assembly is connected with the vehicle body through the suspension shaft, and the damping shock absorber is connected with the drive axle assembly and the vehicle body at both ends, so that the drive axle assembly can float up and down relative to the vehicle body.

[0005] The utility model discloses the following advantages after adopting the above technical scheme: first, the walking system is arranged at the left and right sides of the vehicle body respectively, so that the middle region of the vehicle body is released, and the battery assembly is installed in the region, that is, on the vehicle body and between the left and right walking systems, effectively solving the problem of less battery installation space in the past, so that a battery with larger capacity can be equipped, and the endurance of the all-terrain vehicle is improved significantly, secondly, the driving axle assembly and the vehicle body are connected through the suspension shaft, and the damping shock absorber is matched, so that the driving axle assembly can float up and down relative to the vehicle body, the condition that the driving axle assembly and the vehicle body float synchronously is changed, the damping effect is improved greatly, the all-terrain vehicle runs more smoothly, and finally, the electric control assembly controls the speed of each group of walking system driving motor, realizes differential steering of the left and right wheels of the vehicle body, and the left and right wheels no longer rotate synchronously, the steering radius is reduced, the steering difficulty and inflexibility are solved, and the flexibility and controllability of the all-terrain vehicle are improved.

[0006] Further, the damping shock absorbers of all the walking systems are symmetrically arranged with the center line of the vehicle body in the front-rear direction as the reference.

[0007] The symmetric arrangement ensures the balance of the damping force of the left and right sides of the all-terrain vehicle, the impact force from the ground can be distributed more evenly, the bumping is effectively absorbed and relieved, and the balance of the all-terrain vehicle during running is ensured as much as possible. When the all-terrain vehicle runs on complex and changeable terrain, the road conditions on the left and right sides of the all-terrain vehicle are often different, one side may be a protruding stone, and the other side may be a concave pit. The symmetrically distributed damping shock absorbers can work independently and cooperatively according to the different road conditions on the left and right sides, effectively buffer the impact force from the left and right sides, and avoid the inclination of the all-terrain vehicle due to excessive or insufficient damping force on one side. The symmetrically distributed damping shock absorbers can also make the weight distribution of the left and right sides of the all-terrain vehicle more uniform. The more uniform weight distribution can make the all-terrain vehicle maintain better stability under various road conditions, and reduce the probability of rollover and other dangerous situations caused by the shift of the center of gravity.

[0008] Further, the driving axle assembly is connected with a downward extending limiting piece, the bottom end of the limiting piece is lower than the bottom surface of the vehicle body and is provided with a limiting portion bent inwardly to the vehicle body, and the top of the limiting portion has a gap with the bottom surface of the vehicle body.

[0009] The limiting piece is provided with the limiting portion bent inwardly to the vehicle body, and the top of the limiting portion has a gap with the bottom surface of the vehicle body, so that the excessive upward and downward or leftward and rightward displacement of the driving axle assembly can be prevented when the all-terrain vehicle runs. When the all-terrain vehicle runs on rough road surface or shakes due to steering, acceleration or deceleration, the limiting portion can play a role to limit the excessive displacement of the driving axle assembly, so that the all-terrain vehicle can maintain a more stable posture, and the running safety and control stability are further improved.

[0010] Further, the wheels at least include a front wheel and a rear wheel arranged on the same side of the vehicle body and along the front-rear direction of the vehicle body, and the front and rear ends of the drive axle assembly are respectively provided with a gear bag for transmission connection with the front wheel and the rear wheel.

[0011] By the foregoing technical solution, the gear bag can more accurately transmit the power of the drive axle assembly to the front wheel and the rear wheel, and as much as possible avoid excessive power loss in the transmission process, so that the front wheel and the rear wheel can obtain more sufficient power in different driving states of the all-terrain vehicle such as starting, accelerating and climbing, and the power performance and driving efficiency of the all-terrain vehicle are improved. The gear bag, i.e. the main reducer and differential part in the differential assembly, can realize speed reduction and torque increase through the gear meshing of the main reducer, and convert the high-speed and low-torque power of the drive motor into the low-speed and high-torque power required for the all-terrain vehicle to start and climb. When the all-terrain vehicle turns, the differential plays a differential function to automatically adjust the speed difference between the front wheel and the rear wheel, so that the all-terrain vehicle can turn smoothly, and the all-terrain vehicle can better adapt to various working conditions, greatly enhancing the off-road capability and adaptability of the all-terrain vehicle.

[0012] Further, the drive axle assembly includes a drive axle plate, a bridge pipe and a universal joint, the drive axle plate is provided with two and connected by the bridge pipe, an installation space for fixing the gear bag and the drive motor is formed between the two drive axle plates, the drive motor is transmissionally connected with the gear bag through the universal joint, and the bridge pipe is used to connect with the suspension shaft.

[0013] By the foregoing technical solution, the drive axle assembly includes two drive axle plates connected by the bridge pipe, and an installation space for fixing the gear bag and the drive motor is formed between the two drive axle plates, so as to more fully utilize the structural space, make the installation of the gear bag and the drive motor compact and orderly, as much as possible avoid the mutual interference between the components, thereby as much as possible ensure the stable operation of each component, and also optimize the overall layout of the all-terrain vehicle, improve the space utilization, and provide convenience for the reasonable arrangement of other functional modules of the all-terrain vehicle. The drive motor is transmissionally connected with the gear bag through the universal joint, the universal joint can flexibly transmit power at different angles, effectively compensate the relative displacement and angle deviation between the drive motor and the gear bag due to the driving vibration of the all-terrain vehicle, terrain changes and other factors, and as much as possible ensure the continuity and stability of power transmission.

[0014] Further, an installation plate for installing the gear bag and the drive motor is connected between the two drive axle plates.

[0015] By the foregoing technical solution, the installation plate specifies the exact installation position of the drive motor and the gear bag, improves the assembly efficiency, and also helps to optimize the overall layout of the drive axle assembly, so as to make the space utilization between the components more reasonable, and avoid the problems of space waste and component interference caused by disordered layout.

[0016] Further, the vehicle wheels at least include a front wheel and a rear wheel arranged on the same side of the vehicle body and along the front-rear direction of the vehicle body, and the center point of the line between the front wheel and the rear wheel is taken as the origin, the interval of the gravity center position of the battery assembly from the center point in the X-axis direction is L1, and 0≤L1≤300mm, and the interval of the gravity center position of the battery assembly from the center point in the Y-axis direction is L2, and 0≤L2≤300mm.

[0017] By the above technical solution, the gravity center position of the battery assembly is limited in the interval of 0-300mm from the center point of the line between the front wheel and the rear wheel in the X-axis and Y-axis directions, so as to ensure the weight distribution of the all-terrain vehicle as much as possible, and the all-terrain vehicle can maintain a good balance state during driving, and the risk of rollover caused by gravity center deviation is reduced. Whether on a flat road or in a complex terrain, the all-terrain vehicle can as much as possible move forward stably. If the gravity center of the battery assembly exceeds the interval, the gravity center of the all-terrain vehicle will deviate, the load of the front wheel and the rear wheel will be uneven, and the all-terrain vehicle is prone to tilting at the front or the rear during driving, which affects the driving stability and increases the difficulty of operation.

[0018] Further, the gravity center of the electric control assembly is located above the battery assembly.

[0019] By the above technical solution, the gravity center position of the electric control assembly is limited in the appropriate interval from the gravity center of the vehicle body in the X-axis direction, which helps to maintain the balance of the all-terrain vehicle as a whole. When the all-terrain vehicle drives, whether it is straight driving, turning or dealing with complex road conditions, reasonable gravity center distribution can make the all-terrain vehicle maintain a stable posture, reduce the risk of rollover caused by gravity center deviation, and ensure driving safety. The gravity center of the electric control assembly is located above the battery assembly, which makes full use of the space above the battery assembly and avoids the waste of the internal space of the all-terrain vehicle, so that the internal layout of the all-terrain vehicle is more compact and reasonable. When the gravity center of the electric control assembly is less than 0mm or greater than 500mm from the gravity center origin of the vehicle body in the X-axis direction, the load distribution of the front wheel and the rear wheel of the all-terrain vehicle will be unreasonable, the front of the all-terrain vehicle is prone to lifting when accelerating, and the rear of the all-terrain vehicle is prone to tilting when braking, which affects the operation stability and riding comfort of the all-terrain vehicle.

[0020] Further, the suspension shaft penetrates the vehicle body and extends from the left and right sides of the vehicle body and is connected with the drive axle assemblies on the left and right sides of the vehicle body.

[0021] By the technical scheme, the suspension shaft penetrates the vehicle body and connects the driving axle assemblies on the left and right sides, so that various forces borne by the all-terrain vehicle during driving, such as impact force of the road surface and gravity of the all-terrain vehicle, are more evenly distributed on the entire vehicle body structure, thereby helping to reduce the force bearing of the local vehicle body and reduce the risk of structural fatigue and damage.

[0022] Further, the wheels at least include front wheels and rear wheels arranged on the same side of the vehicle body and along the front-rear direction of the vehicle body, and the center point of the line between the front wheels and the rear wheels is taken as the origin, the gravity center of the suspension shaft is located at a distance interval L4 of 150mm≤L4≤650mm from the center point in the X-axis direction, and the gravity center of the suspension shaft is located at a distance interval L5 of 0≤L5≤300mm from the center point in the Y-axis direction.

[0023] By the technical scheme, the gravity center of the suspension shaft is relatively close to the center plane of the all-terrain vehicle, so that the weight of the all-terrain vehicle is better distributed, and the stability and maneuverability of the all-terrain vehicle are improved. If L4<150mm, the gravity center of the suspension shaft is too close to the front, the vehicle nose sinks seriously when the all-terrain vehicle brakes, the rear wheel has insufficient grip, and the braking distance is lengthened; when the all-terrain vehicle accelerates, the vehicle nose is easily lifted too much, which affects the acceleration performance and the stability of the steering. When L4>650mm, the gravity center of the suspension shaft is located at the rear, the vehicle tail sinks when the all-terrain vehicle brakes, the steering effect of the vehicle nose is poor, the all-terrain vehicle is slow to react when steering, the steering deficiency is obvious, the driver needs to turn the steering wheel more greatly, and the driving difficulty is increased. When L5>300mm, the gravity center of the suspension shaft is too high, the gravity center of the all-terrain vehicle is also high, the roll stability is greatly reduced when the all-terrain vehicle turns or is subjected to a lateral force, and a rollover accident is prone to occur, which seriously threatens the driving safety.

[0038] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0039] like Figures 1 to 7 As shown, this utility model provides an all-terrain vehicle platform, including a walking system 12, a vehicle body 11, a suspension axle 122, a battery assembly 15, and an electronic control assembly 14. The walking system 12 has at least two sets and is respectively located on the left and right sides of the vehicle body 11. The battery assembly 15 is located on the vehicle body 11 and between the left and right walking systems 12. Each walking system 12 includes wheels, a drive axle assembly 126, a drive motor 121, and a damping shock absorber 161. The drive motor 121 is connected to the wheels through the drive axle assembly 126. The electronic control assembly 14 controls the speed of the drive motor 121 of each walking system 12 to enable differential steering of the wheels on the left and right sides of the vehicle body 11. The drive axle assembly 126 is connected to the vehicle body 11 through the suspension axle 122. The two ends of the damping shock absorber 161 are respectively connected to the drive axle assembly 126 and the vehicle body 11 so that the drive axle assembly 126 can float up and down relative to the vehicle body 11.

[0040] Firstly, the walking systems 12 are arranged on the left and right sides of the vehicle body 11 respectively, so that the middle area of the vehicle body 11 is released, and the battery assembly 15 is installed on the vehicle body 11 between the left and right walking systems 12, which effectively solves the problem of less battery installation space in the prior art. In this way, a battery with larger capacity can be provided, and the endurance of the all-terrain vehicle is significantly improved. Secondly, the driving axle assembly 126 is connected to the vehicle body 11 through the suspension shaft 122, and the damping shock absorber 161 is arranged, so that the driving axle assembly 126 can float up and down relative to the vehicle body 11. The synchronous floating state of the driving axle assembly 126 and the vehicle body 11 is changed, the damping effect is greatly improved, and the all-terrain vehicle runs more smoothly. Finally, the electric control assembly 14 controls the speed of each set of walking system 12 driving motor 121, realizes differential steering of the left and right wheels of the vehicle body 11, and no longer synchronously rotates the left and right wheels, which reduces the steering radius, solves the problems of difficult steering and inflexibility, and improves the flexibility and maneuverability of the all-terrain vehicle.

[0041] It should be noted that the all-terrain vehicle platform is not directly used, and the all-terrain vehicle platform can be assembled into an all-terrain vehicle by installing a vehicle shell, a seat, a steering wheel and the like. The effects mentioned in the present application are mainly described when the all-terrain vehicle is in use. The battery assembly 15 can be a storage battery.

[0042] Further, the damping shock absorbers 161 of all the walking systems 12 are symmetrically arranged on the left and right sides of the center line of the vehicle body 11 in the front-rear direction. The symmetric arrangement ensures the balance of the damping force of the left and right sides of the all-terrain vehicle, and can more evenly distribute the impact force from the ground, effectively absorb and relieve bumps, and as much as possible ensure the balance of the all-terrain vehicle during driving. When driving on complex and variable terrains, the road conditions on the left and right sides of the all-terrain vehicle are often different. One side may be a protruding stone, and the other side may be a concave pit. The symmetrically distributed damping shock absorbers 161 can work independently and cooperatively according to the different road conditions on the left and right sides, effectively buffer the impact force from the left and right sides, and avoid tilting of the all-terrain vehicle due to excessive or insufficient damping force on one side. The symmetrically distributed damping shock absorbers 161 can also make the weight distribution on the left and right sides of the all-terrain vehicle more uniform. More uniform weight distribution can make the all-terrain vehicle maintain better stability under various road conditions, and reduce the probability of rollover and other dangerous situations caused by deviation of the center of gravity.

[0043] It should be noted that the number of damping shock absorbers 161 can be determined according to the damping level of the all-terrain vehicle. The higher the damping level, the more damping shock absorbers 161 can be installed.

[0044] In order to compare the excessive floating of the drive axle assembly 126 to cause the all-terrain vehicle to produce additional vibration and shaking during driving, in the application, the drive axle assembly 126 is connected with a downward extending limiting piece 162, the bottom end of the limiting piece 162 is lower than the bottom surface of the vehicle body 11 and is provided with a limiting portion 163 bent inwardly of the vehicle body 11, the top of the limiting portion 163 has a gap 164 with the bottom surface of the vehicle body 11, which can prevent the drive axle assembly 126 from excessive up and down or left and right deviation when the all-terrain vehicle is driving, when the all-terrain vehicle is driving on rough road surface, or shaking due to turning, acceleration, deceleration, the limiting portion 163 can play a role to limit the excessive displacement of the drive axle assembly 126, so that the all-terrain vehicle maintains a more stable posture, further improves the driving safety and control stability.

[0045] It should be noted that the drive axle assembly 126 on both sides of the vehicle body 11 is provided with a limiting piece 162, which can be a limiting plate, and the limiting plate is L-shaped.

[0046] In the embodiment, the wheels include front wheels 124 and rear wheels 125 located on the same side of the vehicle body 11 and arranged along the front and rear directions of the vehicle body 11, and the front and rear ends of the drive axle assembly 126 are respectively provided with tooth packs 123 for transmission connection with the front wheels 124 and the rear wheels 125. The tooth pack 123 can more accurately transmit the power of the drive axle assembly 126 to the front wheels 124 and the rear wheels 125, and avoid as much as possible the excessive loss of power during transmission, so that the all-terrain vehicle can obtain more sufficient power under different driving conditions such as starting, accelerating and climbing, and improve the power performance and driving efficiency of the all-terrain vehicle. The tooth pack 123 is the main reducer and differential part in the differential assembly, which can realize speed reduction and torque increase through the gear engagement of the main reducer, and convert the high speed and low torque power of the drive motor 121 into the low speed and high torque power required for the all-terrain vehicle to start and climb. When the all-terrain vehicle turns, the differential plays a differential function to automatically adjust the speed difference between the front wheels 124 and the rear wheels 125, so that the all-terrain vehicle can turn smoothly, and the all-terrain vehicle can better adapt to various working conditions, greatly enhancing the off-road capability and adaptability of the all-terrain vehicle.

[0047] In order to further improve the stability of the all-terrain vehicle, the wheels at least include front wheels 124 and rear wheels 125 arranged on the same side of the vehicle body 11 and along the front-rear direction of the vehicle body 11. The center point of the line connecting the front wheels 124 and the rear wheels 125 is taken as the origin, the interval of the gravity center position of the battery assembly 15 in the X-axis direction from the center point is L1, 0≤L1≤300mm, and the interval of the gravity center position of the battery assembly 15 in the Y-axis direction from the center point is L2, 0≤L2≤300mm. The front-rear and left-right weight distribution of the all-terrain vehicle is as uniform as possible, the all-terrain vehicle can maintain a good balance state during driving, the risk of rollover caused by gravity center deviation is reduced, and the all-terrain vehicle can stably move forward as much as possible whether on flat roads or in complex terrain. If the gravity center of the battery assembly 15 exceeds the interval, the gravity center of the all-terrain vehicle will deviate, causing uneven load of the front wheels 124 and the rear wheels 125, and the all-terrain vehicle is prone to tilting at the front or the rear during driving, affecting driving stability and increasing the difficulty of operation.

[0048] Preferably, L1 and L2 are both 0, and the vehicle can achieve more balanced weight distribution in each direction, so that the vehicle can maintain high balance stability in the static and driving states.

[0049] Further, the interval of the gravity center position of the electric control assembly 14 in the X-axis direction from the origin is L3, 0≤L3≤500mm, and the gravity center position of the electric control assembly 14 is above the battery assembly 15. Limiting the gravity center position of the electric control assembly 14 in the X-axis direction to a suitable interval from the gravity center of the vehicle body 11 helps to maintain the balance of the all-terrain vehicle as a whole. When the all-terrain vehicle is driving, whether it is driving in a straight line, turning or dealing with complex road conditions, reasonable gravity center distribution can make the all-terrain vehicle maintain a stable posture, reduce the risk of rollover caused by gravity center deviation, and ensure driving safety. The gravity center of the electric control assembly 14 is above the battery assembly 15, which fully utilizes the space above the battery assembly 15, avoids waste of the internal space of the all-terrain vehicle, and makes the internal layout of the all-terrain vehicle more compact and reasonable. When the gravity center of the electric control assembly 14 is less than 0mm or greater than 500mm in the X-axis direction from the origin of the gravity center of the vehicle body 11, the load distribution of the front wheels 124 and the rear wheels 125 of the all-terrain vehicle will be unreasonable, the front of the all-terrain vehicle is prone to lift when accelerating, and the rear of the all-terrain vehicle is prone to tilt when braking, affecting the control stability and ride comfort of the all-terrain vehicle.

[0050] Preferably, L3 is 0, which further makes the weight distribution of the all-terrain vehicle more balanced, thereby further improving the stability of the all-terrain vehicle.

[0051] It should be noted that the all-terrain platform is also provided with an antenna system 13, which is arranged on the vehicle body 11 and electrically connected with the electric control assembly 14, and is used for receiving external signal transmission to control the driving and turning of the all-terrain platform and the operation of each module.

[0052] In this embodiment, the drive axle assembly 126 includes drive axle plates 1262, a bridge pipe 1263 and a universal joint 1264. The two drive axle plates 1262 are provided and connected by the bridge pipe 1263. The installation space of the fixed tooth pack 123 and the drive motor 121 is formed between the two drive axle plates 1262. The structural space is more fully utilized. The installation of the tooth pack 123 and the drive motor 121 is compact and orderly. Interference between components is avoided as much as possible. Thus, stable operation of each component is ensured as much as possible. Meanwhile, the overall layout of the all-terrain vehicle is optimized. The space utilization is improved. The reasonable arrangement of other functional modules of the all-terrain vehicle is facilitated. The drive motor 121 is drivingly connected to the tooth pack 123 through the universal joint 1264. The universal joint 1264 can flexibly transmit power at different angles. The relative displacement and angular deviation between the drive motor 121 and the tooth pack 123 due to factors such as driving vibration and terrain change of the all-terrain vehicle is effectively compensated. Continuity and stability of power transmission are ensured as much as possible. The bridge pipe 1263 is used to connect the suspension shaft 122, facilitating assembly. The suspension shaft 122 can be connected to the bridge pipe 1263 through a latch.

[0053] In order to further improve the structural layout of the drive axle assembly 126, an installation plate 1261 for installing the tooth pack 123 and the drive motor 121 is connected between the two drive axle plates 1262. The installation plate 1261 indicates the exact installation position of the drive motor 121 and the tooth pack 123, improving assembly efficiency and optimizing the overall layout of the drive axle assembly 126. The space utilization between components is more reasonable. Space waste and component interference problems caused by disordered layout are avoided.

[0054] The suspension shaft 122 penetrates the vehicle body 11 and extends from the left and right sides of the vehicle body 11. It is connected to the drive axle assemblies 126 on the left and right sides of the vehicle body 11. It can make various forces borne by the all-terrain vehicle during driving, such as impact force of the road and gravity of the all-terrain vehicle, more evenly distributed to the entire vehicle body 11 structure. It helps to reduce the local stress burden of the vehicle body 11 and reduce the risk of structural fatigue and damage.

[0055] In order to further improve the stability of the all-terrain vehicle, the center of the suspension shaft 122 is located in the X-axis direction from the center point of the line connecting the front wheel 124 and the rear wheel 125, and the distance interval is L4, 150mm≤L4≤650mm, and the center of the suspension shaft 122 is located in the Y-axis direction from the center point, and the distance interval is L5, 0≤L5≤300mm. The center of gravity of the suspension shaft 122 is relatively close to the center plane of the all-terrain vehicle, which can realize better distribution of the weight of the all-terrain vehicle, and help to improve the stability and maneuverability of the all-terrain vehicle. If L4<150mm, the center of gravity of the suspension shaft 122 is too close to the front, and the all-terrain vehicle sinks seriously when braking, and the rear wheel 125 has insufficient grip, and the braking distance is lengthened. When the all-terrain vehicle accelerates, the front of the vehicle is easily lifted too much, which affects the acceleration performance and the stability of the steering. When L4>650mm, the center of gravity of the suspension shaft 122 is located at the rear, and the all-terrain vehicle sinks when braking, and the steering effect of the front is poor. When steering, the all-terrain vehicle is relatively slow in response, and the steering is obviously insufficient, and the driver needs to turn the steering wheel more, which increases the driving difficulty. When L5>300mm, the center of gravity of the suspension shaft 122 is too high, and the center of gravity of the all-terrain vehicle is also high. When turning or subjected to lateral force, the roll stability is greatly reduced, and the vehicle is prone to rollover accidents, which seriously threatens the safety of driving.

[0056] It can be understood that in other embodiments, the wheels located on the same side of the vehicle body can also be provided with three, four or the like, and a plurality of wheels are in contact with the ground to form a wider support surface, thereby providing a more stable foundation for the vehicle.

[0057] In addition to the preferred embodiments described above, the utility model also has other embodiments, and all other embodiments obtained by those skilled in the art based on the embodiments in the utility model without creative labor belong to the scope of the utility model claimed.
