Description

Technical Field

[0001] The present invention relates to the technical field of sightseeing field vehicles, and in particular to a field vehicle with a lifting device. Background Art

[0002] In recent years, with the acceleration of tourism and urbanization, various types of sightseeing vehicles have been widely used in tourist attractions, amusement parks, resorts and other places; however, traditional sightseeing vehicles have some significant problems, such as inconvenient luggage handling and difficulty in cleaning the top of the vehicle, which have affected the tourists' experience to a certain extent.

[0003] At present, the sightseeing vehicles commonly seen on the market usually adopt fixed luggage compartments. Passengers need to carry their luggage manually, which is a cumbersome and time-consuming process, especially for the elderly, children or people with limited mobility. At the same time, after the luggage is placed in the luggage compartment, it cannot be conveniently fixed. When the vehicle is running for a long time, the luggage will collide with each other, and the items inside will be damaged. At the same time, fragile items cannot be stored separately, resulting in the items being squeezed and damaged. In addition, the sightseeing vehicles are exposed to the outside for a long time, and dust and debris are easily accumulated on the upper part of the vehicle, which not only affects the appearance, but may also affect the performance and service life of the vehicle. The existing cleaning methods mostly rely on manual operation, which is inefficient and ineffective.

[0004] Therefore, the present invention provides a field vehicle with a lifting device to solve the above problems. Summary of the invention

When the luggage is placed on the lowered lifting mechanism, it can be automatically lifted and fixed under the action of the card box. The device can realize layered storage through the setting of the storage mechanism, and can be fixed under the action of the clamping box, which is convenient for the placement of fragile items. At the same time, layered storage can avoid damage caused by collision between luggage, and further protect the safety of passengers' property. The cleaning component of the device can automatically clean the ceiling without manual operation.

[0008] Preferably, the lifting mechanism includes a fixed frame and a lifting plate, the fixed frame is fixedly installed at one end of the luggage compartment, a sliding frame is slidably connected inside the fixed frame, the top of the sliding frame is fixedly connected to the output end of the driving cylinder, the bottom of the sliding frame is fixedly connected to the side wall of the lifting plate, and the lifting plate is slidably connected to one end inside the luggage compartment.

At this time, the sliding frame slides inside the fixed frame and drives the lifting plate to move downward. When the lifting plate continues to drop, the linkage tooth plate will hit the ground, and the linkage tooth plate will move upward. At the same time, the linkage tooth plate drives the linkage shaft to rotate under the action of the connecting gear. Because the linkage gear is a one-way drive connection, it will not drive the driving screw to rotate at this time. When the linkage shaft rotates, the volute spring is compressed, and the starting box limits the linkage shaft to limit the reversal of the linkage shaft. When the linkage tooth plate is displaced to the limit distance, the lifting plate is lowered to the bottom, and the stop button will engage with the card The inner top wall of the receiving box abuts against the top, and the control driving cylinder stops moving.

The displacement of the linkage tooth plate can drive the linkage shaft to rotate through the connecting gear, and the volute spring is in a compressed state at this time. The linkage shaft drives the starting gear to rotate. At this time, the inclined surface of the telescopic column inside the linkage gear is opposite to the inclined surface of the limiting groove, so that the telescopic spring is in a compressed state. At this time, the starting gear will not drive the connecting gear to rotate. When the linkage shaft is reversed, the starting gear will drive the linkage gear to rotate. When the linkage toothed plate is reset and descended, the connecting gear will not drive the linkage shaft to rotate. Through the one-way driving setting of the connecting gear and the linkage gear, the device can prevent the driving screw from rotating when the linkage shaft of the device is storing energy and rotating, thereby avoiding the phenomenon that the stabilizing plate is clamped when the luggage is not placed on the upper part of the lifting plate, avoiding the phenomenon that the luggage cannot be placed, and at the same time preventing the stabilizing plate from loosening when the linkage toothed plate is reset and descended, thereby ensuring the stabilizing effect.

[0011] Preferably, a card block is fixedly installed on the outer wall of the linkage shaft, and a starting block is slidably connected to the inside of the starting box, and an arc surface is set on one side of one end of the starting block, and the other end is set to a straight surface, the arc surface of the starting block matches the card block, and the other end of the starting block is fixedly connected to one end of the top extension spring, and the other end of the top extension spring is fixedly connected to the inner side wall of the starting box, and the one end of the starting block located inside the starting box is fixedly connected to one end of the starting cable, and the other end of the starting cable is located inside the lifting plate; when the linkage tooth plate of this device moves upward, the linkage shaft will rotate forward.

[0019] 3. The device is set up with a one-way drive connecting the gear and the linkage gear, so that when the linkage shaft of the device rotates to store energy, it will not drive the driving screw to rotate, so as to avoid the phenomenon that the stabilizing plate is clamped when the luggage is not placed on the upper part of the lifting plate, so as to avoid the phenomenon that the luggage cannot be placed. At the same time, it prevents the stabilizing plate from loosening when the linkage gear plate is lowered and reset, thereby ensuring the stabilizing effect.

[0020] 4. Through the setting of the pressing rod and the starting box, the device can automatically start to stabilize after the luggage is placed.

[0021] 5. When the device is in use, in order to avoid damage caused by squeezing of fragile items, the layering plate is moved upward by rotating the adjusting screw to achieve layered storage and avoid squeezing and colliding of luggage. At the same time, the clamping box can clamp the luggage to avoid collision and damage between luggage when the vehicle is driving.

[0022] 6. When the device is in use, when the field vehicle is traveling, in order to prevent the top of the vehicle from being blocked by the accumulation of fallen leaves and other impurities, thereby affecting the viewing and aesthetics, the driving impeller will be driven to rotate when the vehicle is traveling. At this time, under the action of the main shaft, the two-way lead screw will be driven to rotate, thereby driving the cleaning box to move forward and backward, thereby automatically cleaning the top of the vehicle. At the same time, in order to prevent the fallen leaves from being cleaned to the front of the vehicle and causing the vehicle's vision to be blocked, when the cleaning plate of the device cleans to the rear end, the inclined plate 1 will abut against the cleaning plate for upward displacement, and the cleaning plate will be separated from the abutting contact with the top of the vehicle. At this time, the displacement will not achieve the cleaning effect, and when the cleaning box is displaced backward, the inclined plate 2 will abut against the inner wall of the front end of the slide groove, and the cleaning plate will move downward at this time, so that the cleaning plate can clean the top of the vehicle in one direction and avoid affecting the driver's line of sight.

The device can achieve layered storage through the setting of the storage mechanism 4, and can be fixed under the action of the clamping box 7, which is convenient for the placement of fragile items. At the same time, layered storage can avoid damage caused by collision between luggage, and further protect the safety of passengers' property. The cleaning component 9 of the device can automatically clean the ceiling 13 without manual operation.

[0046] As attached Figure 3 As shown, the lifting mechanism 3 includes a fixed frame 301 and a lifting plate 303. The fixed frame 301 is fixedly installed at one end of the luggage compartment 2. The interior of the fixed frame 301 is slidably connected with a sliding frame 302. The top of the sliding frame 302 is fixedly connected to the output end of the driving cylinder 5. The bottom of the sliding frame 302 is fixedly connected to the side wall of the lifting plate 303. The lifting plate 303 is slidably connected to one end inside the luggage compartment 2.

[0047] As attached Figure 4-5As shown, the interior of the card-joint box 6 is rotatably connected with a linkage shaft 601 and a driving screw 602, and a connecting gear 603 is unidirectionally driven on the outer wall of one end of the linkage shaft 601. The interior of the card-joint box 6 is slidably connected with a linkage toothed plate 604, which is meshed with the connecting gear 603. The bottom of the linkage toothed plate 604 passes through the interior of the lifting plate 303 and is located outside its bottom. A reset spring 605 is fixedly installed on the top of the linkage toothed plate 604, and the top of the reset spring 605 is fixedly connected to the inner top wall of the card-joint box 6. A stop button 606 is installed on the side wall of the linkage toothed plate 604, and the stop button 606 is electrically connected to the control end of the driving cylinder 5. ; A starting gear 607 is installed on the outer wall of the other end of the linkage shaft 601, and a linkage gear 608 is unidirectionally driven and connected on the outer wall of one end of the driving screw 602, and the linkage gear 608 is meshed with the starting gear 607. A threaded box 609 is threadedly connected on the outer wall of the driving screw 602, and a stabilizing plate 610 is fixedly installed on the outer wall of one end of the threaded box 609, and the stabilizing plate 610 is slidably connected to the inner wall of the card box 6; a starting box 611 is fixedly installed on the inner wall of the card box 6, and the starting box 611 matches the linkage shaft 601, and a volute spring is installed on the outer wall of the linkage shaft 601, and the other end of the volute spring is fixedly connected to the inner wall of the card box 6;When the device is in use, the driving cylinder 5 is first started to drive the sliding frame 302 to move downward. A slot hole is provided on the outer wall of the fixed frame 301 to facilitate the sliding of the sliding frame 302. At this time, the sliding frame 302 slides inside the fixed frame 301 and drives the lifting plate 303 to move downward. When the lifting plate 303 continues to descend, the linkage tooth plate 604 will contact the ground, and the linkage tooth plate 604 will move upward. At the same time, the linkage tooth plate 604 drives the linkage shaft 601 under the action of the connecting gear 603. The linkage gear 608 is a one-way drive connection, so it will not drive the driving screw 602 to rotate. When the linkage shaft 601 rotates, the scroll spring is compressed, and the start box 611 limits the linkage shaft 601 to limit the reverse rotation of the linkage shaft 601. When the linkage gear plate 604 moves to the limit distance, the lifting plate 303 drops to the bottom, and the stop button 606 will hit the inner top wall of the card box 6 to control the driving cylinder 5 to stop the action. At this time, it is convenient to place the luggage on the upper part of the lifting plate 303. The lower part of the movable tooth plate 604 is a smooth plate. When placing luggage, the linkage shaft 601 will be reversed. Since the bottom of the linkage tooth plate 604 is a smooth plate, the linkage tooth plate 604 will not be driven to move, but the driving screw 602 will be driven to rotate, and the stabilizing plate 610 will move outward. The stabilizing plate 610 fixes the luggage. After the luggage is placed, the driving cylinder 5 is started to reset, and the lifting plate 303 moves upward. The linkage tooth plate 604 is reset under the action of the reset spring 605. At this time, the reverse rotation of the connecting gear 603 will not cause The movable linkage shaft 601 rotates to prevent the fixed luggage from loosening; the device can automatically stop the lifting plate 303 of the device from descending to the bottom by setting the linkage tooth plate 604, avoiding the phenomenon of excessive or insufficient descent, ensuring the safety during use. At the same time, the device can automatically clamp and stabilize the luggage when placing it, avoiding the phenomenon of shaking, and the displacement of the stabilizing plate 610 of the device and the descent of the lifting plate 303 can achieve the effect of linkage, and the descent of the lifting plate 303 can drive the movement of the stabilizing plate 610. ;

[0048] As attached Figure 6As shown, an inner hole 612 is provided inside the linkage shaft 601, and a telescopic column 613 is slidably connected inside the inner hole 612. One end of the telescopic column 613 is in the shape of a triangle. A telescopic spring 614 is fixedly installed on one end of the telescopic column 613 located inside the inner hole 612. The other end of the telescopic spring 614 is fixedly connected to the inner wall of the inner hole 612. A limiting groove 615 is provided on the inner wall of the connecting gear 603. The limiting groove 615 matches the telescopic column 613. The connection structure between the connecting gear 603 and the linkage shaft 601 is the same as the connection structure between the linkage gear 608 and the driving screw 602. When the linkage tooth plate 604 of the device is displaced upward, the telescopic column 613 is extended out under the action of the telescopic spring 614. At this time, the straight surface of the telescopic column 613 is opposite to the straight surface of the limiting groove 615. The displacement of the linkage tooth plate 604 can drive the linkage shaft 601 to rotate through the connecting gear 603. At this time, the volute spring is in a compressed state. 1 drives the starting gear 607 to rotate. At this time, the inclined surface of the telescopic column 613 inside the linkage gear 608 is opposite to the inclined surface of the limiting groove 615, so that the telescopic spring 614 is in a compressed state. At this time, the starting gear 607 will not drive the connecting gear 603 to rotate. When the linkage shaft 601 reverses, the starting gear 607 will drive the linkage gear 608 to rotate. When the linkage gear plate 604 is reset and descended, the connecting gear 603 will not drive the linkage shaft 601 to rotate; through the one-way driving setting of the connecting gear 603 and the linkage gear 608, the device can make the linkage shaft 601 of the device store energy and rotate without driving the driving screw 602 to rotate, so as to avoid the phenomenon that the luggage is not placed on the upper part of the lifting plate 303 and the stabilizing plate 610 is clamped, so as to avoid the phenomenon that the luggage cannot be placed, and at the same time, the stabilizing plate 610 is prevented from loosening when the linkage gear plate 604 is reset and descended, so as to ensure the stabilizing effect.

[0049] As attached Figure 7As shown, a block 616 is fixedly installed on the outer wall of the linkage shaft 601, and a starting block 617 is slidably connected inside the starting box 611.
