Description

Technical Field

[0001] This invention relates to the field of mobile exhibition vehicle technology, and more specifically, to a smart control device for direct drinking water in mobile exhibition vehicles. Background Technology

[0002] Currently, existing mobile exhibition and sales vehicles for direct drinking water only have a fixed, flat base on the loading platform of the vehicle. Various direct drinking water devices are directly placed and fixed on the base, without any height-adjustable support fixtures. This results in a fixed placement height for the equipment, making it difficult to adjust flexibly. In actual exhibitions, the specifications and models of the water tanks, direct drinking water units, and filling terminals vary, with significant differences in overall size and height. The fixed installation height cannot be adapted to the normal viewing height of people. In particular, the placement of small and short devices is too low, requiring visitors to bend over to observe and operate the equipment. Large water tanks and other equipment are placed too high, severely obscuring their internal pipes, water meters, and other core structures, making them difficult to clearly display. This fixed installation structure greatly affects the exhibition and demonstration effect of direct drinking water equipment, reduces the professionalism of product display and the visitor experience, and fails to meet the diverse and visual exhibition and display needs.

[0024] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0025] The following is in conjunction with the appendix Figures 1-7 This embodiment will be described in further detail.

[0026] This embodiment of a mobile sales vehicle direct drinking water intelligent control device includes a vehicle body 1 and a loading platform 2. Multiple base plates 3 are fixedly installed on the upper surface of the loading platform 2. Multiple support cylinders 4 are fixedly installed on the upper surface of the base plates 3. A lifting plate 5 for placing the device is provided on the upper surface of the base plates 3. Multiple support rods 6, with their lower ends inserted into corresponding support cylinders 4, are fixedly installed on the lower surface of the lifting plate 5. A fixing component for clamping and limiting the device is provided on the upper surface of the lifting plate 5. A fixing cylinder 7 is fixedly installed on the upper surface of the base plates 3. The fixing cylinder 7 has an upward-opening fixing cavity, and a lifting component for driving the lifting plate 5 to adjust its height is provided within the fixing cavity. A support component for supporting the lifting plate 5 is provided on the upper surface of the base plates 3.

[0027] In this embodiment, the main body includes a vehicle body 1 and a loading platform 2 located at the rear of the vehicle body 1. The loading platform 2 is the basic load-bearing area for carrying all the direct drinking water equipment inside the vehicle. Multiple base plates 3 are rigidly fixed to the upper surface of the loading platform 2. The base plates 3 serve as the bottom mounting base for the entire adjustable tooling. Multiple support cylinders 4 are vertically fixed to the upper surface of each base plate 3. A lifting plate 5 is installed above the base plate 3. The lifting plate 5 is used to place different specifications of direct drinking water equipment such as water tanks, mini direct drinking water main units, direct drinking water accessories, filling machines, drinking water platforms, and water meter display platforms. Multiple support rods 6 are vertically fixed to the lower surface of the lifting plate 5. The support rods 6 are inserted one-to-one into the support cylinders 4. The support cylinders 4 and the support rods 6 cooperate with each other to form a vertical guiding constraint on the lifting plate 5, ensuring that the lifting plate 5 can only rise and fall smoothly in the vertical direction and will not deviate horizontally. A fixing component is assembled on the upper end face of the lifting plate 5. The fixing component is used to clamp and limit various direct drinking water devices placed on the lifting plate 5. A fixing cylinder 7 is also fixed on the upper end face of the base plate 3. The fixing cylinder 7 has an upward-opening fixing cavity. The lifting component is assembled inside the fixing cavity. The lifting component serves as a power structure to drive the lifting plate 5 to lift as a whole, thereby completing the height adjustment of the equipment. During the on-site demonstration and sales, different models and sizes of direct drinking water equipment are placed stably on the lifting platform 5, and the equipment is clamped and positioned by the fixing components. Then, the lifting components are activated to lift the lifting platform 5 and the equipment as a whole, adjusting the equipment to a display height suitable for visitors to view and personnel to operate. Through the lifting components, the lifting platform 5 can be driven to freely adjust the height of various direct drinking water equipment, which can adapt to the normal viewing line and operating height of the human body, and adapt to the display needs of equipment of different sizes such as water tanks, direct drinking water main units, and filling terminals. The lifting components drive the lifting platform 5 to descend to the lowest limit position in the opposite direction, and the equipment moves down with the lifting platform 5, lowering the center of gravity of the vehicle, reducing the risk of equipment shaking and tipping when the vehicle bumps, turns, and brakes, and improving transportation stability. When the lifting assembly completes the height adjustment of the lifting plate 5, the supporting assembly supports the lifting plate 5. At this time, the supporting assembly can share the load of the lifting assembly and extend the service life of the lifting assembly.

[0028] In this embodiment, the upper end face of the lifting plate 5 is provided with opposite slots 8 with a T-shaped cross section; The fixing assembly includes two clamping plates 9 located on the upper surface of the lifting plate 5. The lower surfaces of the two clamping plates 9 are fixedly installed with opposing T-shaped locking blocks 10. The locking blocks 10 are respectively inserted into corresponding locking slots 8. The ends of the two clamping plates 9 that are close to each other are bent upward to form clamping parts 11. Multiple insertion rods 12 for insertion into the equipment are fixedly installed on the side walls of the two clamping parts 11 that are close to each other.

[0029] In this embodiment, two sets of T-shaped slots 8 are opened on the upper surface of the lifting plate 5, which are arranged oppositely and run horizontally through the lifting plate 5. The fixing component includes two clamping plates 9, and T-shaped blocks 10 are fixed to the lower ends of the two clamping plates 9 respectively. The shape of the blocks 10 is completely matched with the T-shaped slots 8. The blocks 10 slide and engage inside the slots 8, so that the two clamping plates 9 can slide freely along the slots 8 to adapt to drinking water devices of different widths and shapes. The ends of the two clamping plates 9 that are close to each other are bent upward to form vertical clamping parts 11. Multiple insert rods 12 are fixed on the opposite side walls of the two clamping parts 11. When the device is placed between the two clamping plates 9, the two clamping plates 9 slide together and the clamping parts 11 fit against the side wall of the device. The insert rods 12 can be inserted into the reserved holes in the device housing to complete the device limiting clamping from the side, so as to prevent the device from sliding horizontally during lifting and vehicle movement. The T-shaped slots 8 and T-shaped blocks 10 are fixed to the T-shaped slots 9. The snap-fit ​​structure of the type card block 10 enables continuous adjustment of the spacing of the clamping plate 9, allowing it to adapt to various equipment with different shapes such as water tanks, main units, and filling terminals without additional openings, thus meeting the diverse layout display needs of the exhibition vehicle. The upper surface of the lifting plate 5 has multiple round holes, and the upper surface of the clamping plate 9 is equipped with bolts 13. The lower end of the bolts 13 passes through the clamping plate 9 and is threaded into the corresponding round hole. The upper surface of the lifting plate 5 has multiple round holes arranged in an array, and the top of each clamping plate 9 is equipped with a locking bolt 13. The bolt 13 passes downward through the clamping plate 9 and is threaded into the corresponding round hole of the lifting plate 5. When the operator slides the clamping plate 9 to the clamping position that fits the equipment, he tightens the bolts 13 downward. The bottom end of the bolt 13 engages with the thread of the round hole to press the clamping plate 9, locking the clamping plate 9 onto the lifting plate 5. This prevents the clamping plate 9 from slipping or loosening due to vibration or lifting force. If it is necessary to change the equipment or adjust the clamping distance, simply loosen the bolts 13 and the clamping plate 9 can be slid again. The installation and adjustment are convenient and suitable for use scenarios where equipment is frequently changed and the layout is adjusted at the exhibition site.

[0030] In this embodiment, a threaded rod 14 is fixedly installed on the lower end face of the lifting plate 5; The lifting assembly includes a rotating cylinder 15 rotatably mounted in a fixed cavity, and the lower end of a threaded rod 14 is threadedly inserted into the rotating cylinder 15.

[0031] In this embodiment, a threaded rod 14 is vertically fixed at the center of the lower end face of the lifting plate 5; a rotating cylinder 15 is rotatably assembled inside the fixed cylinder 7 on the base plate 3 through a bearing. The inner ring of the rotating cylinder 15 has an internal thread. The threaded rod 14 is screwed into the rotating cylinder 15 to form a threaded pair. The lifting assembly achieves height adjustment of the lifting plate 5 by means of threaded transmission. When the rotating cylinder 15 rotates in the forward direction, the threaded rod 14 extends upward under the threaded drive, driving the lifting plate 5 and the above equipment to lift as a whole. When the rotating cylinder 15 rotates in the reverse direction, the threaded rod 14 is screwed into the rotating cylinder 15, and the lifting plate 5 falls downward. The self-locking characteristic of the thread can ensure that the lifting plate 5 automatically locks after stopping at any height. The display height of the equipment can be maintained without additional locking parts, which is stable and reliable. The outer wall of the rotating cylinder 15 is fixedly fitted with a first gear 16, and the upper end face of the base plate 3 is fixedly installed with a motor 17. The output shaft of the motor 17 is fixedly installed with a second gear 18 that meshes with the first gear 16. The motor 17 serves as the lifting power source. After being powered on, the output shaft of the motor 17 drives the second gear 18 to rotate. The second gear 18 meshes and drives the first gear 16 to rotate synchronously with the rotating cylinder 15. The torque is amplified through gear transmission, providing sufficient power for the lifting of the threaded rod 14. It can support the smooth lifting of heavy equipment such as water tanks filled with water. The motor 17 can be connected to the equipment intelligent management system to realize one-button lifting and lowering by electric control. Operators can quickly adjust the display height of the equipment at the exhibition site, making the operation simple and labor-saving.

[0032] In this embodiment, a support groove 19 is provided on the outer side wall of the support cylinder 4, and a support block 20 with one end inserted into the corresponding support groove 19 is fixedly installed on the outer side wall of the support rod 6.

[0033] In this embodiment, when the lifting plate 5 is raised to the maximum allowable height, the support block 20 abuts against the top edge of the support groove 19, restricting the support rod 6 from continuing to move upward, preventing the threaded rod 14 from dislodging from the rotating cylinder 15, and avoiding the lifting plate 5 and the equipment from falling. When the lifting plate 5 is lowered to the lowest transport position, the support block 20 abuts against the bottom edge of the support groove 19, restricting the lifting plate 5 from moving excessively downward. At the same time, it works with the support cylinder 4 and the support rod 6 to share the vertical load of the equipment. This structure constrains the lifting stroke of the lifting plate 5 throughout the entire process, accurately limiting the maximum display height of the equipment.

[0034] In this embodiment, a corresponding support 21 is fixedly installed on the lower end face of the lifting plate 5, and a support shaft 22 is fixedly installed inside the support 21. A corresponding sliding groove 23 with a T-shaped cross section is opened on the upper end face of the base plate 3. The support assembly includes two movable seats 24 located on the upper surface of the base plate 3. A slider 25 with one end inserted into the corresponding slide groove 23 is fixedly installed on the lower surface of the movable seat 24. A movable shaft 26 is fixedly installed inside the movable seat 24. A connecting rod 27 is rotatably sleeved on the outer side wall of the movable shaft 26. The upper end of the connecting rod 27 is rotatably connected to the corresponding support shaft 22. A limiting member is provided on the upper surface of the base plate 3 to limit the movement of the movable seat 24.

[0035] In this embodiment, one end of the connecting rod 27 is connected to the outer side of the movable shaft 26 via a bearing, and the other end of the connecting rod 27 is connected to the support shaft 22 via a bearing. During the lifting and lowering adjustment of the lifting plate 5, the lifting plate 5 moves smoothly up and down in the vertical direction, which can drive the connecting rod 27, which is hinged at both ends, to swing synchronously. The lower end of the swinging connecting rod 27 pulls the movable seat 24, so that the movable seat 24 slides horizontally along the T-shaped slide groove 23 of the base plate 3 via the slider 25. The overall sliding process is smooth and without jamming, and will not interfere with or hinder the height adjustment action of the lifting plate 5. When the lifting plate 5 is adjusted to the preset display height, the limit lock is operated. The horizontal position of the fixed movable seat 24 is fixed. The locked movable seat 24 limits the lifting plate 5 through the connecting rod 27 and the support 21, effectively restricting the downward displacement of the lifting plate 5. At this time, the two connecting rods 27 form a stable oblique rigid support structure. Most of the vertical load of the lifting plate 5 and the direct drinking water equipment above it can be directly transferred to the base plate 3 for bearing through the connecting rod 27 and the movable seat 24. There is no need for the threaded transmission pair composed of the threaded rod 14 and the rotating cylinder 15 to bear the load alone. This greatly reduces the wear and tear caused by long-term pressure and vibration of the threaded transmission pair, and significantly improves the overall service life and operational stability of the lifting assembly.

[0036] In this embodiment, a movable block 28 is fixedly installed on one side wall of the movable seat 24; The limiting component includes multiple limiting seats 29 fixedly installed on the upper surface of the base plate 3. A limiting block 30 is fixedly installed between two limiting seats 29. A limiting rod 31 is rotatably installed between two limiting seats 29. A limiting cylinder 32 is threadedly sleeved on the outer side wall of the limiting rod 31. A limiting groove is opened on the outer side wall of the limiting cylinder 32 for the limiting block 30 to be inserted. A moving plate 33 for overlapping the corresponding moving block 28 is fixedly installed on the outer side wall of the limiting cylinder 32.

[0037] In this embodiment, the two ends of the limiting rod 31 are rotatably installed in the corresponding limiting seat 29 through bearings. After the height of the lifting plate 5 is adjusted to the position, the limiting rod 31 is rotated. The limiting rod 31 is threadedly engaged with the limiting cylinder 32. The limiting cylinder 32 is constrained by the limiting block 30 and the limiting groove and cannot rotate. It can only move axially along the limiting rod 31. The limiting cylinder 32 drives the outer moving plate 33 to move towards the moving block 28 until the moving plate 33 completely abuts against the moving block 28. The moving seat 24 is abutted and limited by the moving plate 33. When the lifting plate 5 moves down, the slider 25 cannot move horizontally along the sliding groove 23. The connecting rod 27 supports the fixed angle and stably bears the load of the lifting plate 5. If the height of the lifting plate 5 needs to be adjusted again, the limiting rod 31 is rotated in the opposite direction. The limiting cylinder 32 drives the moving plate 33 to move backward and disengage from the moving block 28. The moving seat 24 is released from the limit and the slider 25 can slide freely. The lifting assembly can then drive the lifting plate 5 to rise and fall normally. One end of the limiting rod 31 extends out of the limiting seat 29. A knob 34 for driving the limiting rod 31 to rotate is fixedly installed on the extended end of the limiting rod 31. The operator can easily drive the limiting rod 31 to rotate by rotating the knob 34. In actual limiting operation, after the height of the lifting plate 5 is adjusted to the right position, the knob 34 drives the limiting rod 31 to rotate. The threaded connection between the limiting rod 31 and the limiting cylinder 32 drives the transmission. At the same time, the limiting block 30 locks the limiting cylinder 32 circumferentially, so that the limiting cylinder 32 can only move linearly along the axial direction of the limiting rod 31. During the translation of the limiting cylinder 32, the outer moving plate 33 moves closer to the moving block 28 until the moving plate 33 is completely and tightly abutted, realizing the limiting and fixing of the moving seat 24. At this time, the lifting plate 5 moves down, the slider 25 cannot move horizontally along the slide groove 23, and the support angle of the connecting rod 27 is completely fixed, so that it can continuously and stably bear the vertical load of the lifting plate 5. When the height of the lifting plate 5 needs to be adjusted again, the reverse rotation knob 34 drives the limit rod 31 to reverse, drives the limit cylinder 32 to retract axially, so that the moving plate 33 is separated from the moving block 28, and the limit constraint on the moving seat 24 is released. The slider 25 can slide freely along the slide groove 23 again, and the lifting assembly can normally drive the lifting plate 5 to complete the lowering adjustment operation. The overall operation is simple and convenient, and the limit and unlocking actions are reliable and stable.

[0038] In practical use, the direct drinking water equipment is placed stably on the lifting plate 5 to prevent the entire vehicle from shaking or shifting during the exhibition. Then, the clamping plate 9 is slid to allow the locking block 10 to slide along the slot 8, so that the clamping part 11 fits against the outer wall of the equipment, and the insertion rod 12 is inserted into the pre-drilled hole of the equipment. The bolt 13 is then tightened to lock the clamping plate 9, which can adapt to different specifications of equipment and prevent the equipment from slipping or tipping over. Afterwards, the knob 34 is rotated in the opposite direction to drive the limiting rod 31 to rotate, causing the limiting cylinder 32 and the moving plate 33 to retract and disengage from the moving block 28, thus unlocking the moving seat 24 and ensuring that the lifting adjustment is not interfered with by any mechanism. The motor 17 is started to cause the second gear 18 to mesh with the first gear 16, driving the rotating cylinder 15 to rotate. The rotating cylinder 15 drives the threaded rod 14 to extend upwards, lifting the lifting plate 5. The support rod 6 slides vertically upwards along the support cylinder 4, and the support block 20 moves along the support groove 19, serving as a travel limit to prevent the thread from unraveling and falling. The lifting plate 5... The lifting mechanism simultaneously moves the support 21 and support shaft 22 upwards, pulling the connecting rod 27 to swing. This pushes the movable seat 24 to automatically slide along the slide groove 23 using the slider 25 to adapt to the support tilt angle. After the equipment is adjusted to a height suitable for viewing and operation, the motor 17 is turned off. The threaded pair self-locking can temporarily fix the lifting height. Rotating the knob 34 in the forward direction drives the limit rod 31 to rotate. The limit block 30, which is inserted into the limit groove of the limit cylinder 32, constrains the circumferential rotation of the limit cylinder 32. The limit cylinder 32 only moves forward along the axial direction of the limit rod 31, causing the movable plate 33 to press against the movable block 28 and lock the movable seat 24. This makes the connecting rod 27 form a stable oblique support, greatly reducing the load-bearing pressure of the threaded rod 14, reducing thread wear, and extending the service life of the lifting assembly. After the exhibition, rotating the knob 34 in the reverse direction causes the movable plate 33 to retract and disengage from the movable block 28, unlocking the movable seat 24. The motor 17 is then started in reverse, driving the rotating cylinder 15 to rotate in the opposite direction and retract the threaded rod 14. The lifting plate 5... The descent causes the connecting rod 27 to swing back, the moving seat 24 to retract inward, and the support rod 6 to slide down to the support block 20 and abut against the bottom of the support groove 19, lowering it to the transport low position. This reduces the center of gravity of the vehicle and avoids the risk of the equipment tipping over during braking due to bumps. After reaching the position, the motor 17 is turned off, and finally all the bolts 13 are loosened. The clamping plates 9 are slid to both sides to disengage the insertion rod 12 from the equipment, making it easy to remove the direct drinking water equipment.

[0039] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
