Technical Field
[0001] This utility model belongs to the technical field of tracked all-terrain vehicles, specifically relating to a tracked all-terrain vehicle chassis. Background Technology
[0002] When floods occur, the first priority is to solve the problem of people being trapped. Because tracked all-terrain vehicles are amphibious, they can enter the water directly without preparation and travel on the water to quickly transfer trapped people into the disaster area.
[0003] In existing tracked all-terrain vehicles, the roof frame often serves the function of loading cargo. However, in actual use, the roof frame of tracked all-terrain vehicles is a certain height off the ground, which makes it inconvenient for users to transport cargo to the frame, resulting in some inconvenience in loading and unloading cargo and making it unsuitable for use.
[0004] Therefore, a tracked all-terrain vehicle chassis is needed to solve the problem that in the existing technology, the chassis on the top of the tracked all-terrain vehicle is a certain height off the ground, which makes it inconvenient for users to transport goods to the chassis, resulting in some inconvenience in loading and unloading goods. Utility Model Content
[0005] The purpose of this utility model is to provide a tracked all-terrain vehicle chassis to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a tracked all-terrain vehicle frame, comprising an all-terrain vehicle body, a frame fixed to the top of the all-terrain vehicle body, a support seat fixed to one side surface of the all-terrain vehicle body, an adjustment seat provided on the top of the support seat, a second motor fixed to the bottom surface of the support seat, a first threaded rod rotatably connected to one end of the surface of the support seat, the bottom of the first threaded rod passing through the support seat and fixed to the output end of the second motor, a first threaded sleeve threadedly connected to the outer circumferential surface of the first threaded rod, one end of the first threaded sleeve fixed to the surface of the adjustment seat, a limiting shaft fixed to the other end of the top surface of the adjustment seat, a limiting sleeve slidably sleeved on the outer circumferential surface of the limiting shaft, one end of the limiting sleeve fixed to the surface of the adjustment seat, a stand fixed to one side of the top of the frame, a toothed seat provided to one side of the stand, a movable seat sleeved on the outside of the toothed seat, and a push plate fixed to the bottom of the movable seat.
[0007] It should be noted in the solution that a third motor is fixed to the surface of one end of the movable seat, the output end of the third motor passes through the movable seat and is rotatably connected to the inner surface of the movable seat, and a gear is fixedly sleeved on the outer peripheral surface of the third motor, and the gear is meshed with the gear seat.
[0008] It is worth noting that a T-shaped limiting groove is provided on the bottom surface of the tooth seat, and a T-shaped limiting block is slidably inserted inside the limiting groove. The bottom of the limiting block passes through the limiting groove and is fixed to the top surface of the push plate.
[0009] Furthermore, it should be noted that the inner cavity surface of the stand is rotatably connected to a second threaded rod, and the outer circumferential surface of the second threaded rod is threadedly connected to a second threaded sleeve. The surface of the second threaded sleeve is in contact with the inner cavity surface of the stand, and one side of the second threaded sleeve passes through the stand and is fixed to the surface of one side of the toothed seat.
[0010] In a preferred embodiment, a first motor is fixed to the surface of the top of the stand, and the top of the second threaded rod passes through the stand and is fixed to the output end of the first motor.
[0011] In a preferred embodiment, the top diameter of the outer peripheral surface of the first threaded rod and the limiting shaft is greater than the bottom diameter of their outer peripheral surface, and the top diameter of the outer peripheral surface of the first threaded rod and the limiting shaft is greater than the hole diameter of the first threaded sleeve and the limiting sleeve.
[0012] Compared with the prior art, the tracked all-terrain vehicle chassis provided by this utility model has at least the following beneficial effects:
[0013] (1) By placing the goods on the top of the adjustment seat and raising it to a certain position, the third motor is turned on so that the push plate can push the goods into the depth of the all-terrain vehicle body, which makes it easier for the user to transport the goods to the inside of the vehicle frame in sequence, thereby improving the convenience of loading the goods and making the process less time-consuming and laborious, thus improving the practicality of the device.
[0014] (2) By starting the first motor, the second threaded sleeve can drive the toothed seat and the push plate to move in the vertical direction, which makes it easier to adjust the distance between the push plate and the platform frame. This makes it easier to adjust the push plate to a position away from the platform frame after the adjustment seat raises the goods to the same level as the inner surface of the platform frame, thereby further improving the applicability and practicality of the device.

[0020] Please see Figures 1-4 This utility model provides a tracked all-terrain vehicle frame, including an all-terrain vehicle body 1, a frame 2 fixed to the top of the all-terrain vehicle body 1, a support seat 5 fixed to one side surface of the all-terrain vehicle body 1, an adjustment seat 6 provided on the top of the support seat 5, a second motor 7 fixed to the bottom surface of the support seat 5, a first threaded rod 8 rotatably connected to one end of the surface of the support seat 5, the bottom of the first threaded rod 8 passing through the support seat 5 and fixed to the output end of the second motor 7, a first threaded sleeve 9 threadedly connected to the outer circumference of the first threaded rod 8, and one end of the first threaded sleeve 9 fixed to the surface of the adjustment seat 6. A limiting shaft 10 is fixed to the other end of the top surface of the adjusting seat 6. A limiting sleeve 11 is slidably sleeved on the outer circumferential surface of the limiting shaft 10. One end of the limiting sleeve 11 is fixed to the surface of the adjusting seat 6. A stand 3 is fixed to one side of the top of the platform 2. A toothed seat 12 is provided on one side of the stand 3. A movable seat 13 is sleeved on the outside of the toothed seat 12. A push plate 15 is fixed to the bottom of the movable seat 13. By placing the goods on the top of the adjusting seat 6 and then starting the second motor 7 to make the first threaded sleeve 9 rotate, the adjusting seat 6 can lift the goods to the same level as the bottom of the inner cavity surface of the platform 2.
[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that a third motor 14 is fixed to the surface of one end of the movable seat 13. The output end of the third motor 14 passes through the movable seat 13 and is rotatably connected to the inner surface of the movable seat 13. A gear 18 is fixedly sleeved on the outer circumferential surface of the third motor 14. The gear 18 is meshed with the gear seat 12. By starting the third motor 14, the output end of the third motor 14 can drive the gear 18 to rotate, thereby applying a force to the movable seat 13 in a certain direction under the meshing action between the gear 18 and the gear seat 12.
[0022] Further as Figure 4As shown, it is worth noting that a T-shaped limiting groove 19 is provided on the bottom surface of the gear seat 12. A T-shaped limiting block 20 is slidably inserted inside the limiting groove 19. The bottom of the limiting block 20 passes through the limiting groove 19 and is fixed to the top surface of the push plate 15. Due to the connection relationship of the limiting block 20 and the fact that it can only move horizontally in the inner cavity of the limiting groove 19, the movable seat 13 can only move horizontally when subjected to the force generated by the meshing action between the gear 18 and the gear seat 12.
[0023] Further as Figure 3 As shown, it is worth noting that the inner cavity surface of the support 3 is rotatably connected to a second threaded rod 16, and the outer circumferential surface of the second threaded rod 16 is threadedly connected to a second threaded sleeve 17. The surface of the second threaded sleeve 17 is in contact with the inner cavity surface of the support 3. One side of the second threaded sleeve 17 passes through the support 3 and is fixed to one side of the toothed seat 12. The top surface of the support 3 is fixed to a first motor 4, and the top of the second threaded rod 16 passes through the support 3 and is fixed to the output end of the first motor 4. Since the inner cavity surface of the support 3 can play a resisting and limiting role against the second threaded sleeve 17, when the first motor 4 is started to make the second threaded rod 16 rotate, the second threaded sleeve 17 can move vertically under the cooperation between the internal thread structure on its inner wall and the external thread structure on the outer circumferential surface of the second threaded rod 16.
[0024] This solution has the following working process: In actual use, when the user needs to transport goods to the top of the all-terrain vehicle body 1, by placing the goods on the top of the adjusting seat 6, when the second motor 7 is started, the limiting sleeve 11 and the limiting shaft 10 can limit the adjusting seat 6, making it only able to move in the vertical direction. Thus, when the second motor 7 drives the first threaded rod 8 to rotate, the cooperation between the internal thread structure on the inner wall of the first threaded sleeve 9 and the external thread structure on the outer circumference of the first threaded rod 8 allows the adjusting seat 6 to drive the goods to move vertically upward, so that the goods can be raised to the same level as the bottom of the inner cavity surface of the vehicle frame 2. Then, by turning on the third motor 14, the gear 18 can rotate. Thus, under the meshing action between the gear 18 and the gear seat 12, and with the limiting action of the limiting groove 19 and the limiting block 20 on the movable seat 13, the movable seat 13 can drive the push plate 15 to move in the horizontal direction, so that the first... The second threaded rod 16 can move to a position where the goods are away from the platform 2. Then, by turning on the first motor 4, the inner cavity surface of the support 3 can act as a stop and limit against the second threaded sleeve 17. As the second threaded rod 16 rotates, the second threaded sleeve 17 can move vertically downwards due to the interaction between the internal thread structure on its inner wall and the external thread structure on the outer circumference of the second threaded rod 16. This allows the toothed seat 12 to move to the same horizontal height as the goods. Then, by turning on the third motor 14 and causing its output end to rotate in the opposite direction, the gear 18 can rotate. Under the meshing action between the gear 18 and the toothed seat 12, and with the limiting action of the limiting groove 19 and the limiting block 20 on the movable seat 13, the movable seat 13 can drive the push plate 15 to move horizontally. This allows the push plate 15 to push the goods to the depth of the platform 2 to complete the loading operation.
[0025] As can be seen from the above working process: by placing the goods on the top of the adjusting seat 6 and raising it to a certain position, the third motor 14 is turned on so that the push plate 15 can push the goods into the depth of the all-terrain vehicle body 1, which makes it convenient for the user to transport the goods to the interior of the platform 2 in sequence, thereby improving the convenience of loading the goods and making the process less time-consuming and laborious, thus improving the practicality of the device. By starting the first motor 4, the second threaded sleeve 17 can drive the tooth seat 12 and the push plate 15 to move in the vertical direction, which makes it easy to adjust the distance between the push plate 15 and the platform 2. This allows the push plate 15 to be adjusted to a position away from the platform 2 after the adjusting seat 6 raises the goods to the same level as the inner surface of the platform 2, thus further improving the applicability and practicality of the device.
[0026] Further asFigure 4 As shown, it is worth noting that the top diameter of the outer circumferential surface of the first threaded rod 8 and the limiting shaft 10 is larger than the bottom diameter of their outer circumferential surface, and the top diameter of the outer circumferential surface of the first threaded rod 8 and the limiting shaft 10 is larger than the hole diameter of the first threaded sleeve 9 and the limiting sleeve 11. Through the shape setting of the first threaded rod 8 and the limiting shaft 10, the adjusting seat 6 can be prevented from disengaging under the abutting action of the top of the outer circumferential surface of the first threaded rod 8 and the first threaded sleeve 9, and under the abutting action of the top of the outer circumferential surface of the limiting shaft 10 and the limiting sleeve 11, thus improving the stability of the device operation.
[0027] In summary: By placing the goods on top of the adjusting seat 6 and raising it to a certain position, the third motor 14 is activated, allowing the push plate 15 to push the goods deeper into the all-terrain vehicle body 1. This facilitates the user's sequential delivery of goods to the interior of the platform 2, improving the convenience of loading operations and making the process less time-consuming and laborious, thus enhancing the practicality of the device. By activating the first motor 4, the second threaded sleeve 17 drives the toothed seat 12 and the push plate 15 to move vertically, making it easy to adjust the distance between the push plate 15 and the platform 2. This prevents the adjustment seat 6 from raising the goods to the same level as the inner surface of the platform 2, allowing for easy adjustment of the push plate 15 to a position away from the platform 2, further improving its applicability and practicality. The shape of the first threaded rod 8 and the limiting shaft 10 prevents the adjusting seat 6 from disengaging due to the contact between the top of the outer circumference of the first threaded rod 8 and the first threaded sleeve 9, and the contact between the top of the outer circumference of the limiting shaft 10 and the limiting sleeve 11, thus improving the stability of the device's operation.
[0028] The first motor 4, the second motor 7, and the third motor 14 can be purchased from the market. The first motor 4, the second motor 7, and the third motor 14 are equipped with power supplies. This is a mature technology in the field and has been fully disclosed. Therefore, it will not be repeated in the specification.
