Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a scratch-resistant lifting equipment for automobile dashboards. Background Technology

[0002] In the automotive manufacturing industry, the instrument panel assembly is a core interior component in the cockpit that integrates functions, human-machine interaction, safety protection, and aesthetic design. Its quality directly determines the driving experience of consumers and the safety performance of the vehicle. With the rapid development of automotive intelligence and connectivity, the structure and materials of the instrument panel assembly have undergone two key changes, which have placed higher demands on the hoisting operations in the production process. The proportion of display screens has increased significantly, and large-size touch screens are now commonly integrated into instrument panel assemblies. These types of displays have weak impact and scratch resistance. In the automotive assembly workshop, the hoisting of the instrument panel assembly is a crucial process connecting the pre-assembly of interior components with the assembly of the driver's cabin. It requires the use of lifting equipment to transfer the pre-assembled instrument panel assembly from the pre-assembly station to the driver's cabin, precisely hoisting it to its installation position and securing it. Currently, the industry commonly uses traditional metal lifting equipment for this purpose. While these lifting equipment offer advantages such as high strength and load-bearing capacity...

[0003] Traditional metal lifting tools have rigid metal contact surfaces with high surface roughness, which can easily cause hard friction or impact when in contact with the instrument panel assembly, resulting in damage to multiple parts. If the metal hook comes into contact with the edge of the display screen glass during clamping or transportation, scratches will be generated. Although these scratches do not affect the function, they do not meet the factory standard of zero defects in appearance and require rework to replace the display screen. If the impact force is large, it may cause the glass substrate to crack, directly causing the instrument panel assembly to be scrapped. Utility Model Content

[0004] This utility model solves the problems in related technologies and proposes a scratch-resistant hanger for automobile dashboards.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a scratch-resistant hanger for automotive dashboards, comprising a lifting component, an upper suction component, and a lower suction component. The lifting component includes a lifting frame, with rotating seats vertically fixed on both sides of the top surface of the lifting frame. One end of the lifting frame is fixed with an assembly hole seat, which is fixedly assembled with an external movable truss. The other end of the lifting frame is rotatably connected to an adjusting hydraulic cylinder. The upper suction component includes a rotating frame, which is rotatably connected to the rotating seat. Multiple upper suction vacuum suction cups are provided on the bottom surface of the rotating frame. A push rod is horizontally fixed on the other end of the rotating frame, and the push rod is rotatably connected to the output end of the adjusting hydraulic cylinder. The lower suction component includes a clamping frame and a lower suction vacuum suction cup. The clamping frame is vertically slidably inserted into the lifting frame, and a lower suction vacuum suction cup is horizontally provided at the front of the clamping frame. Protective frames are horizontally fixed on both sides of the clamping frame, and an airbag is fixed on the outer side of the protective frame. The airbag is used to isolate the lifting frame from the automotive dashboard assembly.

[0006] As a preferred option, an airbag is horizontally fixed to the lower side of the hoisting frame, and a rubber pad is fixed to the outer side of the airbag.

[0007] As a preferred option, multiple guide columns are fixed horizontally and vertically on the bottom surface of the rotating frame, and guide cylinders are vertically slidably inserted into the multiple guide columns.

[0008] As a preferred embodiment, a downward pressure spring is vertically fixed at the top of the guide cylinder, and the top of the downward pressure spring is fixed on the bottom surface of the rotating frame.

[0009] As a preferred embodiment, a hole frame is horizontally fixed on the front end face of the card frame, and a sliding column is horizontally slidably inserted on the hole frame, and a lower suction vacuum cup is horizontally fixed on the front end face of the sliding column.

[0010] As a preferred embodiment, a horizontal translation spring is installed inside the hole frame, and the two ends of the translation spring are fixed to the end of the sliding column and the frame, respectively.

[0011] As a preferred embodiment, the lifting frame has multiple threaded holes through horizontal threads, and the rear end face of the clamping frame is fitted with locking bolts through horizontal threads, with the locking bolts threaded into the threaded holes of the lifting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model achieves zero direct metal contact during hoisting through protective material coverage and buffer structure reinforcement, eliminating scratches at the source. The hoisting frame provides full protection, avoiding damage to the cover and wiring harness. The airbag and rubber pad fixed on the bottom side of the hoisting frame can completely isolate the metal steel frame from the surface of the instrument panel assembly. Through the flexible contact between the airbag and the rubber pad, even with clamping force, no dents or scratches will occur, reducing the damage rate of the cover to below 10%. At the same time, the airbag pad on the outside of the protective frame can wrap the wiring harness connector area, avoiding friction between metal parts and plastic connectors, reducing the wear rate of the wiring harness connectors, and completely eliminating potential electrical faults in the future.

[0013] Addressing the high risk of scratches or cracks caused by traditional metal lifting tools coming into contact with display screen glass, this technology reduces the risk of display screen damage to zero through a dual protection design of position avoidance and flexible adaptation. The adjustable suction component precisely avoids the display screen area, slides laterally on the lifting frame via a sliding clip, and is fixed with locking bolts. The suction points of the upper and lower suction components can be precisely adjusted according to the display screen position of different vehicle models' dashboard assemblies, ensuring that all suction structures and protective components avoid the display screen glass and edges. The flexible adsorption technology adapts to curved surfaces, avoiding damage from localized pressure. In the upper suction component, a downward pressure spring pushes the guide cylinder to slide vertically along the guide post, allowing the upper suction vacuum cup to fully conform to the curved structure of the top surface of the instrument panel assembly, ensuring uniform distribution of adsorption force. In the lower suction component, a translation spring pushes the sliding column to move laterally, allowing the lower suction vacuum cup to adapt to irregular structures on the side or bottom surface of the assembly. The rigid hooks of traditional metal hangers can easily exert localized pressure on the edge of the display screen, leading to microcracks in the glass substrate. This technology, through flexible adsorption and adaptive adjustment, ensures that no external force is applied to the display screen area during the adsorption process, reducing the risk of microcracks and fully meeting the factory standard of zero defects in appearance.

[0014] The upper and lower vacuum suction cups adopt a multi-point adsorption design, so the assembly will not have relative displacement even under the impact conditions of the lifting device starting or stopping. Traditional metal lifting devices cause a high percentage of display screen damage due to unstable clamping and starting / stopping collisions. This technology reduces the damage rate of starting / stopping collisions through the synergy of strong adsorption force and buffer structure, and completely solves the industry problem of dynamic damage.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] like Figures 1 to 5As shown, an anti-scratch hanger for automotive dashboards includes a lifting component 1, an upper suction component 2, and a lower suction component 3. The lifting component 1 includes a lifting frame 11, with rotating seats 111 vertically fixed on both sides of the top surface of the lifting frame 11. One end of the lifting frame 11 is fixed with an assembly hole seat 14, which is fixedly assembled with an external movable truss. The other end of the lifting frame 11 is rotatably connected to an adjusting hydraulic cylinder 15. The upper suction component 2 includes a rotating frame 21, which is rotatably connected to the rotating seats 111. Multiple upper suction vacuum suction cups 25 are provided on the bottom surface of the rotating frame 21. The other end of the rotating frame 21 is horizontally fixed with a push rod 26, which is connected to the output end of the adjusting hydraulic cylinder 15. The lower suction component 3 is rotatably connected to the upper suction component 2, which includes a frame 31 and a lower suction vacuum cup 35. The frame 31 is vertically slidably inserted into the lifting frame 11, and the lower suction vacuum cup 35 is horizontally arranged at the front of the frame 31. Protective frames 36 are horizontally fixed on both sides of the frame 31, and airbags 37 are fixed on the outer side of the protective frames 36. The airbags 37 are used to isolate the lifting frame 11 from the automotive dashboard assembly. The lifting frame 11 in the lifting component 1 is mainly used to support the entire device and is connected to the upper suction component 2 through a rotating base 111, so that the upper suction component 2 can be rotated to adjust its direction. The assembly hole seat 14 is used for fixed assembly with the external mobile truss to ensure that the entire device can move stably. The adjusting hydraulic cylinder 15 is rotatably connected to the push rod 26, which can drive the upper suction component 2 to move along the direction of the lifting frame 11 to meet the lifting requirements of different positions. The rotating frame 21 and the upper suction vacuum cup 25 in the upper suction component 2 can adsorb and fix the car dashboard for easy movement; the push rod 26 and the adjusting hydraulic cylinder 15 work together to achieve precise positioning. The clamping frame 31, protective frame 36, and airbag 37 in the lower suction component 3 can fit tightly against the bottom of the dashboard and are fixed by the lower suction vacuum cup 35, providing double protection; the airbag 37 effectively prevents direct contact between the lifting frame 11 and the dashboard assembly, protecting the dashboard from scratches; the sliding design of the clamping frame 31 allows the lower suction component 3 to adapt to dashboards of different thicknesses. Through the coordinated work of its components, this device achieves precise, reliable, and safe movement and lifting of the car dashboard, effectively preventing damage to the dashboard during the lifting process.

[0019] In one embodiment, such as Figure 2 and 3As shown, an airbag plate 12 is horizontally fixed to the lower side of the lifting frame 11, and a rubber pad 13 is fixed to the outer side of the airbag plate 12. The main function of the lifting frame 11 is to serve as a support structure for bearing and securing the lifted items. The horizontally fixed airbag plate 12 can self-adjust according to the shape and weight of the lifted object during the lifting process, thus providing softer and more uniform support at the contact surface, effectively protecting the lifted item from damage. The rubber pad 13 fixed to the outer side of the airbag plate 12 further enhances the cushioning effect of the contact surface, improving the protection performance of the lifted item. Furthermore, the rubber pad 13 also serves to prevent slippage and enhance grip, ensuring a more stable and safe lifting process.

[0020] In one embodiment, such as Figure 2 and 3 As shown, multiple guide posts 22 are horizontally and vertically fixed on the bottom surface of the rotating frame 21, and guide cylinders 24 are vertically slidably inserted onto the guide posts 22. A compression spring 23 is vertically fixed to the top of the guide cylinder 24, and the top of the compression spring 23 is fixed to the bottom surface of the rotating frame 21. The rotating frame 21 serves as a support structure, and the multiple guide posts 22 horizontally and vertically fixed on its bottom surface provide a guiding path for the guide cylinder 24, ensuring the sliding stability of the guide cylinder 24 in the vertical direction. The guide cylinder 24 slides freely up and down on the multiple guide posts 22, and the compression spring 23 is vertically fixed to its top. The elastic force of the compression spring 23 can apply pressure to the outside. When the guide cylinder 24 slides upward, the compression spring 23 is stretched and stores elastic potential energy; when the guide cylinder 24 slides downward, the compression spring 23 is compressed and releases the stored elastic potential energy, generating a pushing or pressing effect on the outside. This design allows the device to maintain good responsiveness and stability when external pressure is applied, while automatically returning to its original position when pressure is not required.

[0021] In one embodiment, such as Figure 2 and 3 As shown, a hole frame 33 is horizontally fixed on the front end face of the frame 31, and a sliding column 34 is horizontally slidably inserted into the hole frame 33. A lower suction vacuum suction cup 35 is horizontally fixed on the front end face of the sliding column 34. A translation spring 38 is horizontally arranged inside the hole frame 33, and both ends of the translation spring 38 are fixed to the ends of the sliding column 34 and the frame 31, respectively. The frame 31 is used to fix and position the entire device. The hole frame 33 is horizontally fixed on the frame 31 to guide the horizontal movement of the sliding column 34. The sliding column 34 can slide in the hole frame 33 to facilitate precise horizontal movement. The lower suction vacuum suction cup 35 is fixed to the front end of the sliding column 34 for adsorbing and transporting workpieces. The translation spring 38 is fixed between the sliding column 34 and the frame 31, providing a force to restore the initial position of the sliding column 34, allowing the system to reset when needed.

[0022] In one embodiment, such as Figure 2 and3 As shown, the lifting frame 11 has multiple horizontally threaded holes. A locking bolt 32 is threaded through the rear end face of the clamping frame 31 and threaded into the screw holes of the lifting frame 11. Multiple rows of horizontally threaded holes are provided on the rear end face of the lifting frame 11 for fixing the clamping frame 31. The rear end face of the clamping frame 31 has horizontally threaded holes through which the locking bolt 32 can be installed, and the locking bolt 32 is screwed into the screw holes of the lifting frame 11 for a fixed connection. The advantage of this design is that the lifting frame 11 provides a stable installation platform through the screw holes, the clamping frame 31 is securely installed through the threaded connection with the lifting frame 11, and fine adjustments can be made to different positions by adjusting the position of the locking bolt 32. The locking bolt 32 acts as a lock, ensuring the stability and safety of the installation structure.

[0023] The working principle of this utility model: First, the assembly hole seat 14 at one end of the lifting frame 11 is fixedly assembled with the external moving truss by bolts. When clamping and lifting the car instrument panel assembly, the airbag plate 12 and rubber pad 13 are horizontally fixed on the bottom surface of the lower side of the lifting frame 11 to avoid the lower steel frame of the lifting frame 11 directly scratching the car instrument panel assembly. Then, according to the specific position of the display screen on the car instrument panel assembly, the locking frame 31 in the multiple lower suction components 3 is slidably adjusted to move laterally on the lifting frame 11 to offset the specific position of the display screen on the car instrument panel assembly, thereby reducing the damage to the display screen on the car instrument panel assembly caused by suction and lifting. Then, the locking bolt 32 is used to lock the specific position of the locking frame 31 in the multiple lower suction components 3. Then, the adjusting hydraulic cylinder 15 at one end of the lifting frame 11 is extended, pushing the rotating frame 21 in the upper suction component 2 to deflect on the rotating seat 111, causing the upper suction vacuum suction cup 25 on the bottom surface of the rotating frame 21 to adhere to the top surface of the car instrument panel assembly. At the same time, in order to adapt to the arc structure of the top surface of the car instrument panel assembly, the lower pressure spring 23 is used to push the guide cylinder 24 to slide vertically down on the guide post 22, so that the upper suction vacuum suction cup 25 can fully adapt to the arc structure of the top surface of the car instrument panel assembly, ensuring the stability of the car instrument panel assembly suction. Meanwhile, protective frames 36 are horizontally fixed on both sides of the frame 31 in the lower suction component 3, and airbag cushions 37 are fixed on the outside of the protective frames 36 to further reduce the damage to the display screen on the car instrument panel assembly by the lifting frame 11 during suction and lifting. In order to adapt to the shape and structure of the car instrument panel assembly, the lower suction component 3 uses a translation spring 38 to push the sliding column 34 on the hole frame 33 to move laterally, which drives the lower suction vacuum suction cup 35 to vacuum suction onto the car instrument panel assembly.

[0024] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
