Description

Technical Field

[0001] The present invention relates to the technical field of mecha equipment, and in particular to a liftable mecha chassis structure. Background Art

[0002] In the current field of mecha equipment, the performance of the mecha chassis plays a decisive role in the overall work efficiency and reliability of the mecha. When facing complex and diverse working environments, traditional mecha chassis expose many problems that need to be solved. In terms of the stability of the supporting structure, some mecha chassis use a simple fixed support method. When carrying a large weight or encountering bumpy roads or external force impacts, the chassis is very likely to shake or even move, seriously affecting the normal operation of the mecha, and failing to provide a stable and reliable support foundation for the upper structure and related equipment of the mecha, resulting in a decrease in the operating accuracy of the equipment, and may even cause failures.

[0003] In terms of height adjustment, most existing mecha chassis height adjustment systems are not accurate and flexible enough. Some adjustment mechanisms rely on manual operation, and the adjustment process is cumbersome and difficult to accurately control the height, which cannot meet the needs of fast and accurate adjustment of the mecha chassis height in practical applications. Some automatic adjustment systems, due to the lack of an effective feedback control mechanism, are prone to overshoot or inadequate adjustment during the adjustment process, making it difficult for the mecha to quickly adapt to the optimal height under different working conditions, limiting the use range and operating efficiency of the mecha.

[0004] In view of the obvious defects of the above-mentioned traditional mecha chassis in terms of support stability and height adjustment, the development of a new mecha chassis structure with a highly stable support structure and capable of precise and flexible height adjustment has become a key issue that needs to be urgently tackled in the industry. Summary of the invention

[0007] Furthermore, the upper surface of the upper cover is symmetrically provided with turning openings, the top ends of the threaded columns extend to the top of the support seat through the set turning openings, and are fixedly connected with a toothed transmission wheel, the outer side walls of the two toothed transmission wheels are meshed and connected with a transmission belt, the upper surface of the upper cover is rotatably connected with a gear, the upper surface of the gear is fixedly connected with a toothed vertical column, the outer side wall of the toothed vertical column is meshed and connected with the inner side wall of the transmission belt, and the upper surface of the upper cover is fixedly connected with a transmission cavity.

[0008] Furthermore, a hollow groove is provided on the upper surface of the transmission cavity, and a transverse groove is symmetrically provided on the inner side wall of the hollow groove, and a toothed power wheel is symmetrically rotatably connected inside the transverse groove, and the toothed power wheel is meshed with gears, and a motor is symmetrically fixedly connected to the upper surface of the transmission cavity, and the output end of the motor extends to the interior of the transmission cavity and is fixedly connected to the toothed power wheel.

[0009] Furthermore, a contact switch is symmetrically fixedly connected to the right side of the upper surface of the upper cover, and the two contact switches are respectively connected to the two motors through wire signals.

[0010] Furthermore, the support cavity includes a sliding cavity, a sliding plate is slidably connected to the interior of the sliding cavity, the upper surface of the sliding plate is fixedly connected to a supporting vertical plate, the top of the supporting vertical plate is fixedly connected to the inner upper surface of the groove, the outer side wall of the supporting vertical plate is symmetrically provided with spring grooves, the interior of the spring grooves is slidably connected with a wedge block, the wedge blocks are fixedly connected to the interior of the spring grooves with a spring, and a plurality of card grooves are symmetrically provided inside the sliding cavity.

[0011] Furthermore, a plurality of electric wheels are symmetrically fixedly connected to the lower surface of the support seat.

[0012] Furthermore, an electric support rod is fixedly connected to the right side of the upper surface of the upper cover, and a switch contact block is fixedly connected to the right side of the electric support rod.

[0013] Furthermore, a dust cover is fixedly connected to the upper surface of the upper cover, and a plurality of threaded adapter cavities are fixedly connected to the upper surface of the dust cover.

[0014] Beneficial effects: During the operation of lifting the mecha chassis, the unique design of the support cavity greatly enhances the stability of the overall structure. The slide plate in the support cavity can slide smoothly in the sliding cavity, and the top of the connected support vertical plate is firmly connected to the groove of the upper cover. When the mecha chassis rises or falls, the support vertical plate moves accordingly. During the movement, the wedge block in the spring groove works with the card slot in the sliding cavity to play a key supporting and fixing role. Whenever the wedge block moves to the position corresponding to the card slot, the spring will quickly push the wedge block into the card slot. At this time, the support vertical plate is firmly locked in this position, providing solid and reliable support for the upper cover, and effectively preventing the upper cover from displacement or shaking in a static state. This design ensures that the mecha chassis can maintain a high degree of stability whether it is static load-bearing or dynamic lifting and lowering, improves the working reliability and safety of the mecha chassis, and can adapt to the needs of various complex environments and working conditions;

[0015] The motor drives the toothed power wheel to rotate, which in turn drives the gear, toothed vertical column, transmission belt and toothed transmission wheel to work together, and finally realizes the rotation of the threaded column to control the lifting and lowering of the upper cover. At the same time, the precise control module composed of the electric support rod and the contact switch plays an important role. When the electric support rod extends to drive the switch contact block to move, once it touches the contact switch, the contact switch will send a signal to accurately control the two motors respectively. Since both motors rotate clockwise, the upper cover can be flexibly raised or lowered by controlling different motors. In addition, when the switch contact block does not contact any contact switch, the power output stops, so that the chassis of the mecha can be accurately adjusted to the required height position. This design not only meets the needs of a variety of usage scenarios, but also greatly improves the efficiency and accuracy of the height adjustment of the mecha chassis, providing strong support for the practical application of the mecha.

DETAILED DESCRIPTION

[0022] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figure 1-Figure 5 As shown, a liftable armor chassis structure comprises a support seat 1, the upper surface of the support seat 1 is symmetrically fixedly connected with a support cavity 2, the upper surface of the support seat 1 is provided with an upper cover 3, the outer side wall of the upper cover 3 is symmetrically provided with grooves 4, the inner upper surfaces of the two grooves 4 are fixedly connected to the top of the support cavity 2, the outer side wall of the upper cover 3 is symmetrically provided with two slide grooves 5, the upper surface of the support seat 1 is symmetrically provided with a slide cavity 6, the inner part of the slide cavity 6 is symmetrically fixedly connected with a cross column 7, the outer side wall of the cross column 7 is rotatably connected with a slider 8 with a hole, the upper surface of the slider 8 with a hole is fixedly connected with a rotation cavity 9, the upper surface of the support seat 1 is symmetrically rotatably connected with a threaded column 10, the outer side wall of the threaded column 10 is threadedly connected with a cross block 11, the outer side wall of the cross block 11 is symmetrically fixedly connected with a transverse rotation cavity 12, the inner part of the rotation cavity 9 is rotatably connected with a support plate 13, and the outer side walls of the opposite ends of the support plate 13 are rotatably connected with the inner part of the adjacent transverse rotation cavity 12;

[0025] When the chassis of the mecha needs to be raised, the driving device is started to drive the threaded column 10 to rotate. Since the threaded column 10 is threadedly connected to the cross block 11, the cross block 11 will move upward along its axial direction when the threaded column 10 rotates. The transverse rotation cavity 12 on the cross block 11 rises accordingly, pulling the support plate 13 that is rotatably connected to it. The other end of the support plate 13 is rotatably connected to the rotation cavity 9 on the perforated slider 8, and the perforated slider 8 can slide on the cross column 7. When the support plate 13 is pulled, the perforated slider 8 will slide in the sliding cavity 6. As the support plate 13 is continuously pulled up, the upper cover 3 is gradually propped up. The upper cover 3 is fixed to the support cavity 2 through the groove 4, and the support cavity 2 is fixed on the support seat 1, so that the entire upper cover and the part connected to it rise steadily, realizing the lifting of the mecha chassis. The descending process is the opposite, the threaded column reverses, the cross block drives the transverse rotation cavity to descend, the support plate falls back, and the upper cover then steadily descends to the initial position.

[0026] In this embodiment, the upper surface of the upper cover 3 is symmetrically provided with a turn mouth 14, the top end of the threaded column 10 extends to the top of the support seat 1 through the set turn mouth 14, and is fixedly connected with a toothed transmission wheel 15, the outer side walls of the two toothed transmission wheels 15 are meshed and connected with a transmission belt 16, the upper surface of the upper cover 3 is rotatably connected with a gear 17, the upper surface of the gear 17 is fixedly connected with a toothed vertical column 18, the outer side wall of the toothed vertical column 18 is meshed and connected with the inner side wall of the transmission belt 16, the upper surface of the upper cover 3 is fixedly connected with a transmission cavity 19, the upper surface of the transmission cavity 19 is provided with a slot 20, and the inner side wall of the slot 20 A transverse rotation groove 21 is symmetrically provided, and a toothed power wheel 22 is symmetrically rotated inside the transverse rotation groove 21, and the toothed power wheel 22 is meshed with the gear 17. A motor 23 is symmetrically fixedly connected to the upper surface of the transmission cavity 19, and the output end of the motor 23 extends to the inside of the transmission cavity 19 and is fixedly connected to the toothed power wheel 22. A contact switch 24 is symmetrically fixedly connected to the right side of the upper surface of the upper cover 3, and the two contact switches 24 are respectively connected to the two motors 23 through wire signals. An electric support rod 28 is fixedly connected to the right side of the upper surface of the upper cover 3, and a switch contact block 29 is fixedly connected to the right side of the electric support rod 28;

[0027] The motor 23 is turned on, and its output end drives the toothed power wheel 22 to rotate in the transverse groove 21. Since the toothed power wheel 22 is meshed with the gear 17, the gear 17 rotates accordingly, thereby driving the toothed vertical column 18 fixed thereto to rotate. The toothed vertical column 18 is meshed with the inner wall of the transmission toothed belt 16, and the transmission toothed belt 16 is meshed with the two toothed transmission wheels 15, so that the two toothed transmission wheels 15 rotate synchronously, and the threaded column 10 fixed to the toothed transmission wheels 15 also starts to rotate. The rotation of the threaded column 10 drives the cross block 11 to move along its axial direction, driving the upper cover 3 to rise or fall through the support plate 13. When the electric support rod 28 is extended, it drives the switch contact block 29 to move. When the switch contact block 29 touches the contact switch 24, the contact switch 24 sends a signal to control the two motors 23 to work respectively, so as to accurately control the lifting position of the upper cover 3. The two contact switches 24 correspond to one motor 23 respectively, and both motors 23 rotate clockwise, so that when the corresponding motor 23 is controlled, the upper cover can be controlled to descend or rise. At the same time, when no contact is made to any of the contact switches 24, the power output can be stopped to achieve precise adjustment of the height of the chassis of the mecha.

[0028] In this embodiment, the support cavity 2 includes a sliding cavity 101, a slide plate 102 is slidably connected inside the sliding cavity 101, and a support vertical plate 103 is fixedly connected to the upper surface of the slide plate 102. The top of the support vertical plate 103 is fixedly connected to the inner upper surface of the groove 4. The outer side wall of the support vertical plate 103 is symmetrically provided with elastic grooves 104, and the inside of the elastic grooves 104 is slidably connected with wedge blocks 105. The wedge blocks 105 are fixedly connected to the inside of the elastic grooves 104 with springs 106. A plurality of card slots 107 are symmetrically provided inside the sliding cavity 101.

[0029] When the upper cover 3 is lifted or lowered, the support vertical plate 103 will move up or down in the sliding cavity 101. This is because the top of the support vertical plate 103 is fixed to the upper surface of the groove 4, and the groove 4 is connected to the upper cover 3. During the movement of the support vertical plate 103, the wedge block 105 in the elastic groove 104 of its outer wall will be squeezed. When the wedge block 105 moves to the position corresponding to the slot 107 in the sliding cavity 101, the elastic action of the spring 106 will push the wedge block 105 to snap into the slot 107. In this way, the support vertical plate 103 is fixed at this position, which can provide stable support for the upper cover 3. When the height of the upper cover 3 needs to be changed, the lifting force of the upper cover 3 will cause the wedge block 105 to overcome the elastic force of the spring 106 and slide out of the slot 107, so that the support vertical plate 103 can continue to slide in the sliding cavity 101 until it reaches the next suitable slot 107 position and snaps in and fixes again, thereby achieving stable support for different heights of the upper cover 3.

[0030] In this embodiment, a plurality of electric wheels 25 are symmetrically fixedly connected to the lower surface of the support seat 1;

[0031] The control system sends a command to the electric wheel 25, and the electric wheel 25 starts to run. Multiple electric wheels work together to adjust the speed and direction according to the command, driving the support base 1 and the entire mecha chassis to move smoothly, and can realize forward and backward movements to meet different movement needs.

[0032] In this embodiment, a dust cover 26 is fixedly connected to the upper surface of the upper cover 3, and a plurality of threaded adapter cavities 27 are fixedly connected to the upper surface of the dust cover 26;

[0033] The dust cover 26 is fixed on the upper cover 3 to isolate dust and other debris. When it is necessary to install equipment or components above the chassis of the mecha, the threaded adapter cavity 27 on the dust cover can be used. Different robot components are firmly installed on the dust cover 26 through matching bolts and other connectors. The whole process realizes the functions of protection and equipment installation expansion.

[0034] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
