Description

Technical Field

[0001] This invention relates to the field of vehicle display technology, and in particular to a vibration suspension structure for a vehicle-mounted floating display. Background Technology

[0002] With the development of automotive intelligence in recent years, especially the rapid development of new energy vehicles, in-vehicle LCD displays have become very important electronic components in automobiles. The common vibration structure in existing in-vehicle displays uses Z-shaped or U-shaped springs to connect the fixed and moving supports, achieving vibration suspension through the elasticity of the springs.

[0003] However, in the existing vibration suspension, Z-shaped springs and U-shaped springs are used as connecting structures to realize the vibration suspension. They are large in size and thick, which cannot meet the needs of thin floating screen products. Moreover, the Z-shaped spring and U-shaped spring structure relies on elasticity to achieve vibration connection. Their resistance to impact, vibration and torsion is weak, and they are prone to torsional deformation. When the floating screen vibrates laterally, it may sway back and forth, resulting in poor vibration stability. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art. This invention provides a vibration suspension structure for a vehicle-mounted floating display screen. The rolling friction suspension is achieved by using steel balls and fixed spring sheets, which makes the suspension itself have good resistance to impact, vibration and torsion, and is not easy to twist and deform, and can achieve stable lateral vibration.

[0005] The technical solution of this invention: A vibration suspension structure for a vehicle-mounted floating display screen, comprising a fixed bracket and a movable bracket. The movable bracket is equipped with a display screen, the fixed bracket is equipped with an electromagnet, and the movable bracket is equipped with an armature. The armature and the electromagnet are attracted to achieve lateral vibration of the movable bracket. The fixed bracket and the movable bracket are connected by a suspension assembly, which includes a fixed spring and steel balls. Steel balls are provided on both the fixed bracket and the movable bracket. The fixed spring includes a first fixed piece, a second fixed piece, and a buffer piece. The first fixed piece is fixedly connected to the fixed bracket, and the second fixed piece is fixedly connected to the movable bracket. The first fixed piece and the second fixed piece are arranged in parallel. A buffer piece is connected between the two ends of the first fixed piece and the second fixed piece to form a rectangular fixed spring. The first fixed piece and the second fixed piece have outwardly curved raised portions corresponding to the steel balls. The steel balls on the fixed bracket roll in cooperation with the inner side of the raised portions of the second fixed piece, and the steel balls on the movable bracket roll in cooperation with the inner side of the raised portions of the first fixed piece. The raised portions have directional channels parallel to the vibration direction.

[0006] Using the above technical solution, when the armature and electromagnet are attracted and the moving bracket moves laterally relative to the fixed bracket, the second fixed plate moves laterally with the moving bracket, while the first fixed plate remains fixed to the fixed bracket. The buffer plate connects the two ends of the first and second fixed plates, providing a buffering effect against vibration. The rectangular fixed spring ensures that the suspension effectively resists impact forces and torques in non-vibration directions, making the lateral vibration of the moving bracket more stable. The fixed bracket has a first raised portion, and the moving bracket has a second raised portion. During lateral vibration, the steel ball of the moving bracket rolls inside the first raised portion. The directional channel is parallel to the vibration direction, allowing the steel ball on the moving bracket to move laterally relative to the first raised portion. The steel ball on the fixed bracket rolls inside the second raised portion. The directional channel of the second raised portion allows the steel ball on the fixed bracket to move laterally relative to the second raised portion. The directional channel allows the fixed spring and the steel ball to move in the vibration direction. The steel ball can roll flexibly, not only providing support in the suspension but also offsetting some of the impact and torque forces through the rolling friction with the raised portion. Elastic suspension requires a large volume of space to achieve the effects of shock resistance and torsional resistance, while rolling friction suspension, which uses steel balls and raised parts, occupies less space and can be used in floating screens.

[0007] A further feature of the present invention is that the fixed support and the movable support are provided with steel ball seats for placing steel balls, and the raised portion is an inverted V-shaped raised portion with an inclined surface that can roll and rub against the steel ball.

[0008] With the above-mentioned further configuration, the steel ball is located between the raised portion and the steel ball seat. The raised portion presses on top of the steel ball to prevent the steel ball from detaching from the steel ball seat. The raised portion is inverted V-shaped, and the inclined surfaces on both sides make the raised portion elastic, which can undergo elastic deformation to apply downward pressure to the steel ball, restricting the steel ball from detaching. Moreover, it is convenient to process, without needing to refer to the diameter of the steel ball. It can directly achieve rolling friction with the steel ball, reducing the processing accuracy requirements of the raised portion and facilitating processing and production.

[0009] A further feature of the present invention is that both ends of the first fixing plate and the second fixing plate are provided with positioning holes, one end of which is a round hole and the other end is a waist hole, and the two waist holes and the two round holes are diagonally arranged on the fixing spring plate.

[0010] With the above further configuration, if torque occurs during the vibration of the suspended screen, the diagonally arranged positioning holes can eliminate part of the impact and torque. The positioning holes have a buffer space in the same direction as the torque, which can buffer the torque and improve the impact and torque resistance of the fixing spring. The diagonally arranged positioning holes facilitate the positioning of the fixing spring and help improve the assembly speed.

[0011] A further feature of the present invention is that the fixed bracket and the movable bracket are provided with positioning pins corresponding to the positioning holes, the positioning pins on the fixed bracket are provided with a first screw hole for fixing with the first fixing plate, and the positioning pins on the movable bracket are provided with a second screw hole for fixing with the second fixing plate.

[0012] With the above-mentioned further configuration, the positioning post includes a first positioning post located on the fixed bracket and a second positioning post located on the movable bracket. The fixing spring and the fixed bracket and the movable bracket are fixed by bolts. The structure is simple, the connection is firm, and the cost is saved. The two first positioning posts are set on both sides of the first stud and the two second positioning posts are set on both sides of the second stud. When torque occurs, the positioning posts located on the outer side can move relative to each other in the buffer space to buffer the torque, so that the suspension has the performance of resisting torque.

[0013] In a further embodiment of the present invention: the first fixing plate and the second fixing plate are elastically connected by a buffer plate, the buffer plate being a U-shaped spring, the U-shaped spring being arranged side by side between the positioning holes at both ends of the first fixing plate and the second fixing plate, and the fixing bracket having a clearance opening corresponding to the U-shaped spring.

[0014] With the above-mentioned further configuration, the U-shaped springs located at both ends of the fixed spring have a good buffering effect. When the moving bracket approaches the fixed bracket, it buffers the moving bracket and improves the feel of vibration. The U-shaped springs are arranged side by side with the positioning holes to reduce the impact of lateral vibration on the positioning pins and positioning holes. The opening can accommodate the U-shaped springs, reducing the space occupied by the suspension.

[0015] A further feature of the present invention is that the fixed support and the moving support are provided with four sets of suspension assemblies, which are distributed on the four corners of the fixed support and the moving support.

[0016] With the above-mentioned further configuration, four sets of suspension components are distributed on the four corners of the outer side of the fixed bracket and the moving bracket, making the vibration of the entire floating screen more stable and the feel better.

[0029] like Figure 1-7As shown, a vibration suspension structure for a vehicle-mounted floating display screen according to the present invention includes a fixed support 1, a movable support 2, and a display screen 3. An electromagnet 11 is provided on the fixed support 1, and an armature 21 is provided on the movable support 2. The armature 21 and the electromagnet 11 are attracted to achieve lateral vibration of the movable support 2. The fixed support 1 and the movable support 2 are connected by a suspension assembly 4. The suspension assembly 4 includes a fixed spring 41 and steel balls 42. Steel balls 42 are provided on both the fixed support 1 and the movable support 2. The fixed spring 41 includes a first fixing plate 43, a second fixing plate 44, and a buffer plate 45. The first fixing plate 43 is fixedly connected to the fixed support 1, and the second fixing plate 44... The first fixing plate 43 and the second fixing plate 44 are fixedly connected to the movable bracket 2. The two ends of the first fixing plate 43 and the second fixing plate 44 are directly elastically connected through the buffer plate 45 to form a rectangular fixing spring plate 41. The first fixing plate 43 is provided with a first raised part 463 that bends outward, and the second fixing plate 44 is provided with a second raised part 464 that bends outward. The steel ball 42 on the fixed bracket 1 rolls with the inner side of the second raised part 464, and the steel ball 42 on the movable bracket 2 rolls with the inner side of the first raised part 463. The raised part 46 is provided with a directional channel 461 parallel to the vibration direction.

[0030] When the armature 21 and electromagnet 11 are attracted, and the moving bracket 2 moves laterally relative to the fixed bracket 1, the second fixed plate 44 moves laterally with the moving bracket 2, while the first fixed plate 43 remains fixed to the fixed bracket 1. The buffer plate 45 connects the two ends of the first fixed plate 43 and the second fixed plate 44, providing a buffering effect against vibration. The rectangular fixed spring plate 41 ensures that the suspension effectively resists impact forces and torques in non-vibration directions, making the lateral vibration of the moving bracket 2 more stable. During lateral vibration, the steel ball 42 of the moving bracket 2 rolls and rubs against the inner side of the first raised portion 463, and the directional channel 461 is parallel to... The vibration direction allows the steel ball 42 on the moving bracket 2 to move laterally relative to the first raised portion 463. The steel ball 42 on the fixed bracket 1 rolls and rubs against the inner side of the second raised portion 464. The directional channel 461 of the second raised portion 464 allows the steel ball 42 on the fixed bracket 1 to move laterally relative to the second raised portion 464. The directional channel 461 allows the fixed spring 41 and the steel ball 42 to move in the vibration direction. The steel ball 42 can rotate flexibly, not only providing support in the suspension, but also offsetting some of the impact and torsional forces through the rolling friction with the inner side of the raised portion 463. Elastic suspension requires a large volume to achieve the effect of impact and torsional resistance, while the rolling friction suspension achieved by the steel ball 42 and the raised portion 463 occupies less volume and can be used in floating screens.

[0031] like Figure 4-7As shown, the fixed support 1 is provided with a first steel ball seat 12, and the movable support 2 is provided with a second steel ball seat 22. The first steel ball seat 12 is located below the second raised portion 464, and the second steel ball seat 22 is located below the first raised portion 463. The steel ball 42 is located between the raised portion 46 and the steel ball seat. The raised portion 46 presses on the steel ball 42 to prevent the steel ball 42 from detaching from the steel ball seat. The raised portion 46 is inverted V-shaped. The inclined surfaces 462 on both sides of the raised portion 46 make the raised portion elastic, which can undergo elastic deformation to apply downward pressure to the steel ball 42, restricting the steel ball 42 from detaching. Moreover, the processing difficulty is low. It can directly achieve rolling friction with the steel ball 42 without referring to the diameter of the steel ball 42, which reduces the processing accuracy requirements of the raised portion 46 and is beneficial to processing and production.

[0032] like Figure 5 As shown, both ends of the first fixing plate 43 and the second fixing plate 44 are provided with positioning holes, one end of which is a round hole and the other end is an oblong hole. The two oblong holes and the two round holes are diagonally arranged on the fixing spring plate 41. During the vibration of the suspended screen, if torque occurs, the diagonally arranged positioning oblong holes 481 can eliminate part of the impact force and torque. The positioning oblong holes 481 have a buffer space in the same direction as the torque, which can buffer the torque and improve the impact resistance and torque resistance of the fixing spring plate 41. The diagonally arranged positioning round holes 82 facilitate the positioning of the fixing spring plate 41 and help improve the assembly speed.

[0033] like Figure 4-7 As shown, the fixed bracket 1 and the moving bracket 3 are provided with positioning pins corresponding to the positioning holes. The positioning pins on the fixed bracket 1 are provided with screw holes for bolting the first fixing plate 43. The positioning pins 52 on the moving bracket 2 are provided with screw holes for bolting the second fixing plate 44. The fixing spring plate 41 and the fixed bracket 1 and the moving bracket 2 are fixed by bolts. The structure is simple, the connection is firm, and the cost is saved. The fixed bracket is provided with the first positioning pin 51 and the first screw hole 13. The moving bracket is provided with the second positioning pin 52 and the second screw hole 23. The first screw pin 13 is located on both sides of the first steel ball seat 12. The first positioning pin 51 is located on the side of the first screw pin 13 away from the first steel ball seat. The second screw pin 23 is located on both sides of the second steel ball seat 22. The second positioning pin 52 is located on the side of the second screw pin 23 away from the second steel ball seat 22. When torque occurs, since the positioning pin is located outside the fixing bolt, it can move relative to the bolt in the buffer space to buffer the torque, so that the suspension has the performance of resisting torque.

[0034] like Figure 4-7As shown, the first fixed plate 43 and the second fixed plate 44 are elastically connected by a buffer plate 45. The buffer plate 45 is a U-shaped spring. The U-shaped spring has a good buffering effect. When the moving bracket 2 approaches the fixed bracket 1, it buffers the moving bracket 2 and improves the feel of vibration. The U-shaped spring is arranged side by side between the positioning holes at both ends of the first fixed plate 43 and the second fixed plate 44 to reduce the impact of lateral vibration on the positioning post and positioning hole. The fixed bracket 1 is provided with a relief opening 14 corresponding to the U-shaped spring. The relief opening 14 can accommodate the U-shaped spring and reduce the space occupied by the suspension.

[0035] like Figure 2 As shown, four sets of suspension components 4 are provided on the fixed bracket 1 and the moving bracket 2. The four sets of suspension components 4 are distributed on the four corners of the fixed bracket 1 and the moving bracket 2, which makes the vibration of the entire floating screen more stable and the feel better.
