Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted display screens, and in particular to a shock-resistant vehicle-mounted display screen. Background Art

[0002] In-car display screens generally refer to devices used to play images or display data in a car. With the rapid development of modern technology, people's requirements for their own quality of life are gradually increasing. Therefore, the proportion of people installing in-car display screens in vehicles is also increasing year by year. In-car display screens can not only allow passengers in the car to watch movies, but also allow drivers to perform route analysis and route selection, so as to provide better travel services for people today.

[0003] However, the current vehicle-mounted display screens still have some shortcomings. For example, a Chinese patent with publication number CN220169131U discloses a shock-resistant vehicle-mounted display screen, which mentions: the set stop plate, the first damping shock-absorbing mechanism, the hinge assembly and the second damping shock-absorbing mechanism enable the protective shell to provide better shock-resistant protection for the vehicle-mounted display screen body, thereby avoiding the vehicle-mounted display screen from seriously shaking when the vehicle is driving on a poor road section, causing the internal parts of the vehicle-mounted display screen to be damaged. The stop plate, the first damping shock-absorbing mechanism and the hinge assembly provide vertical shock-resistant protection for the vehicle-mounted display screen body, while the second damping shock-absorbing mechanism provides lateral shock-resistant protection for the vehicle-mounted display screen body; however, it can only play a protective buffering role in two axial directions, and cannot also play a buffering role in the longitudinal direction. Moreover, when the operator operates the shock-resistant vehicle-mounted display screen, the display screen is prone to shaking, which can easily cause misoperation. Summary of the invention

[0004] Based on this, the purpose of the present invention is to provide a shock-resistant vehicle-mounted display screen that can achieve three-axis buffering and prevent the display screen from shaking when an operator uses the display screen.

[0005] The invention provides the following technical solutions: a shock-resistant vehicle-mounted display screen, comprising a mounting frame with a bottom wall and side walls, an inner cavity formed between the bottom wall and the side walls, a display screen body arranged at the inner cavity of the mounting frame, a plurality of elastic members arranged between the side walls of the display screen body and the side walls of the mounting frame, a first sliding bar arranged at the inner cavity of the mounting frame, a sliding sleeve arranged on the first sliding bar, a first rotating seat rotatably connected to the sliding sleeve, a second rotating seat arranged on a side of the display screen body close to the bottom wall of the mounting frame, and a connecting rod rotatably connected between the second rotating seat and the first rotating seat; the shock-resistant vehicle-mounted display screen also includes a fixing component for limiting the movement of the display screen body.

[0006] Furthermore, the sliding sleeve is slidably connected to the first sliding rod, and damping is present at the movable connections between the sliding sleeve and the first sliding rod, the sliding sleeve and the first rotating seat, the first rotating seat and the connecting rod, and the second rotating seat and the connecting rod.

[0007] Furthermore, buffer pads are provided on the inner sides of the side walls of the installation frame, and the buffer pads correspond to the side walls of the display screen body.

[0008] Furthermore, the fixing component includes a sensor arranged on a side of the side wall of the mounting frame away from the bottom wall, and two groups of locking units respectively arranged on both sides of the inner cavity of the mounting frame, the locking units include a locking member and a driving member and a connecting block connecting the locking member and the driving member, and a locking rod arranged on the display screen body, and the sensor is used to control the driving member to drive the locking member to move in the lateral direction.

[0009] Furthermore, the telescopic end of the driving member is fixedly connected to the connecting block, and the driving member is an electric push cylinder, an air cylinder, or an oil cylinder.

[0010] Furthermore, the locking member includes a main body portion fixedly connected to the connecting block, the main body portion is U-shaped, and a groove portion for accommodating the locking rod is provided in the middle thereof, a first inclined portion portion is provided on a side of the main body portion close to the display screen body, and a second inclined portion portion is provided on the inner side of the main body portion.

[0011] Furthermore, the locking unit further includes a second sliding rod disposed in the inner cavity of the installation frame, and the second sliding rod is slidably connected to the connecting block.

[0012] Furthermore, the shock-resistant vehicle-mounted display screen also includes a shielding assembly, which includes an outer plate fixedly connected to the side wall of the mounting frame, an inner plate arranged on a side of the outer plate close to the bottom wall of the mounting frame, and through holes formed in the middle of the outer plate and the inner plate in sequence.

[0013] Furthermore, a buffer strip is provided at the through hole of the inner plate, and the buffer strip and the inner plate are made of soft material.

[0014] The beneficial effect of the invention is that when the vehicle is bumpy, the springs on the upper and lower sides of the display screen body realize vertical buffering, and the springs on the left and right sides of the display screen body realize lateral buffering. When the display screen body needs front and rear longitudinal buffering, the springs on the upper and lower sides and the left and right sides can all play a buffering role, thereby realizing three-axial buffering. In addition, the infrared sensor will sense the operator's fingers, thereby controlling the electric push cylinders of the two groups of positioning units to start, so that the telescopic ends of the electric push cylinders retract and drive the connecting blocks to move toward the display screen body. The connecting blocks will drive the positioning parts to move toward the display screen body. When the positioning parts contact the display screen body and the positioning parts contact the positioning rod, the display screen body will be restricted. Therefore, when the operator touches and operates the display screen body, the display screen body will not move with it, thereby facilitating the operator to use the display screen body.

DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] like Figure 1-Figure 6 As shown, it is the first embodiment of the present invention, which provides a shock-resistant vehicle-mounted display screen, including a mounting frame 1 with a bottom wall and side walls, an inner cavity formed between the bottom wall and the side walls, a display screen body 2 arranged at the inner cavity of the mounting frame 1, a plurality of elastic members arranged between the side walls of the display screen body 2 and the side walls of the mounting frame 1, a first sliding bar 5 arranged at the inner cavity of the mounting frame 1, a sliding sleeve 6 arranged on the first sliding bar 5, a first rotating seat 7 rotatably connected to the sliding sleeve 6, a second rotating seat 9 arranged on a side of the display screen body 2 close to the bottom wall of the mounting frame 1, and a connecting rod 8 rotatably connected between the second rotating seat 9 and the first rotating seat 7; the shock-resistant vehicle-mounted display screen also includes a fixing component 10 for limiting the movement of the display screen body 2.

[0027] Among them, the shock-resistant vehicle-mounted display screen is installed on the vehicle, the display screen body 2 and the mounting frame 1 are both square, and two elastic members are arranged between the four sides of the display screen body 2 and the four sides of the inner wall of the mounting frame 1. The preferred elastic member is a spring 3. It can be understood that when the vehicle is bumpy, the springs 3 on the upper and lower sides of the display screen body 2 realize vertical buffering, and the springs 3 on the left and right sides of the display screen body 2 realize lateral buffering. When the display screen body 2 needs front and rear longitudinal buffering, the springs 3 on the upper and lower sides and the left and right sides can all play a buffering role; when the display screen body 2 is buffering up and down, the display screen body 2 will drive the second rotating seat 9 to move up and down, and the second rotating seat 9 will drive the connecting rod 8 to swing. In this embodiment, the sliding sleeve 6 is slidably connected to the first sliding rod 5. In other embodiments, the sliding sleeve 6 and the first sliding rod 5 can be fixedly connected. If the sliding sleeve 6 is slidably connected to the first sliding rod 5, the up and down movement of the second rotating seat 9 will drive the connecting rod 8 to swing and will also drive the connecting rod 8 to move up and down. The up and down movement of the connecting rod 8 drives the first rotating seat 7 to move up and down. The swivel seat 7 moves up and down to drive the sliding sleeve 6 to slide on the first sliding rod 5. When the sliding sleeve 6 and the first sliding rod 5 can be fixedly connected, the second swivel seat 9 moves up and down and only drives the connecting rod 8 to swing back and forth; when the display screen body 2 moves left and right, it will drive the second swivel seat 9 to move left and right, and the second swivel seat 9 moves left and right to drive the connecting rod 8 to swing left and right, and the connecting rod 8 swings left and right to drive the first swivel seat 7 to rotate on the sliding sleeve 6. When the display screen body 2 moves back and forth, the display screen body 2 moves back and forth to drive the second swivel seat 9 to move back and forth, and the second swivel seat 9 drives the connecting rod 8 to swing back and forth; it can be seen from the above that the moving distance of the display screen body 2 can be limited by the arrangement of the first sliding rod 5, the sliding sleeve 6, the first swivel seat 7, the connecting rod 8 and the second swivel seat 9, so as to prevent the display screen body 2 from moving too far and colliding with the mounting frame 1, thereby causing damage; further, when the operator needs to use the display screen body 2, the fixing assembly 10 will lock the display screen body 2 in the first time to prevent it from moving, so as to facilitate the operator to use.

[0028] like Figure 3 As shown, the sliding sleeve 6 is slidably connected to the first sliding rod 5, and damping exists at the movable connections between the sliding sleeve 6 and the first sliding rod 5, the sliding sleeve 6 and the first rotating seat 7, the first rotating seat 7 and the connecting rod 8, and the second rotating seat 9 and the connecting rod 8.

[0029] It can be understood that the damping connection at the mutually movable connection between the first sliding rod 5, the sliding sleeve 6, the first rotating seat 7, the connecting rod 8 and the second rotating seat 9 can further play a buffering role. When the vehicle is bumpy, the display screen body 2 shakes, the spring 3 plays the first buffering role, and the damping connection plays the second buffering role.

[0030] like Figure 2As shown, a buffer pad 4 is provided on the inner side of the side wall of the installation frame 1 , and the buffer pad 4 corresponds to the side wall of the display screen body 2 .

[0031] When the vehicle bumps too violently, the display screen body 2 shakes violently and moves too far. In order to further cushion the impact, a cushion pad 4 is provided. When the display screen shakes violently and moves too far, it comes into contact with the cushion pad 4, thereby providing further cushioning. In this embodiment, the cushion pad 4 is an airbag filled with gas. In other embodiments, the cushion pad 4 may be a rubber pad, a silicone pad, or the like.

[0032] like Figure 4 and Figure 5 As shown, the fixing component 10 includes a sensor arranged on a side of the side wall of the mounting frame 1 away from the bottom wall, and two groups of locking units respectively arranged on both sides of the inner cavity of the mounting frame 1, the locking units include a locking member 106 and a driving member and a connecting block 104 connecting the locking member 106 with the driving member, and a locking rod 107 arranged on the display screen body 2, and the sensor is used to control the driving member to drive the locking member 106 to move in the lateral direction.

[0033] Among them, the telescopic end of the driving member is fixedly connected to the connecting block 104, and the driving member is an electric push cylinder 103 or an air cylinder or an oil cylinder, etc. In the present embodiment, it is an electric push cylinder 103, and the sensor is an infrared sensor 101; it can be understood that when the operator needs to use the display screen body 2, the operator's finger will approach the display screen body 2, and the infrared sensor 101 will first sense the operator's finger. At this time, the infrared sensor 101 sends a signal to the controller, and the controller can be set in the center console of the vehicle, or in the installation frame 1, and the controller will control the electric push cylinders 103 of the two groups of card units to start, so that the electric push cylinders 103 can be extended. The retracted end drives the connection block 104 to move toward the display screen body 2, and the connection block 104 drives the positioning member 106 to move toward the display screen body 2. When the positioning member 106 contacts the rear side of the display screen body 2, the display screen will not be able to move backward, so when the operator touches the display screen body 2, the display screen will not move backward. When the positioning rod 107 is located in the middle of the positioning member 106, the display screen body 2 will not be able to move up and down and left and right, so when the operator touches and slides the display screen body 2, the display screen body 2 will not move with it, so that the operator can use the display screen body 2. When the infrared sensor 101 senses the operator's finger, the infrared sensor 101 will also send a signal to the controller, so that the controller controls the telescopic end of the electric push cylinder 103 to extend, so that the positioning member 106 is reset, so that the positioning member 106 is no longer in contact with the display screen body 2 and the positioning rod 107, and the display screen body 2 is active at this time.

[0034] like Figure 6 As shown, the locking member 106 includes a main body 1061 fixedly connected to the connecting block 104, the main body 1061 is U-shaped, and a groove 1064 is provided in the middle for accommodating the locking rod 107, a first inclined portion 1062 is provided on the side of the main body 1061 close to the display screen body 2, and a second inclined portion 1063 is provided on the inner side of the main body 1061.

[0035] It can be understood that when the operator needs to use the display screen main body 2, and the vehicle is bumping and the display screen main body 2 is also shaking, the connecting block 104 drives the main body 1061 of the locking member 106 to move toward the direction close to the display screen main body 2. When the display screen main body 2 moves forward and backward, the main body 1061 can make the main body 1061 more convenient to move to the rear side of the display screen main body 2 through the first inclined surface 1062, and the main body 1061 can make the locking rod 107 more convenient to move to the groove portion 1064 through the second inclined surface 1063, thereby restricting the display screen main body 2, and making it easier for the operator to operate the display screen main body 2.

[0036] The locking unit further includes a second sliding rod 105 disposed in the inner cavity of the installation frame 1 , and the second sliding rod 105 is slidably connected to the connecting block 104 .

[0037] It can be understood that, through the provision of the second sliding rod 105 , the electric push cylinder 103 is more stable when driving the connecting block 104 to move.

[0038] To sum up, when the vehicle is bumpy, the springs 3 on the upper and lower sides of the display screen body 2 realize vertical buffering, and the springs 3 on the left and right sides of the display screen body 2 realize lateral buffering. When the display screen body 2 needs front and rear longitudinal buffering, the springs 3 on the upper and lower sides and the left and right sides can all play a buffering role, thereby realizing three-axial buffering. In addition, the infrared sensor 101 will sense the operator's finger, thereby controlling the electric push cylinder 103 of the two groups of positioning units to start, so that the telescopic end of the electric push cylinder 103 retracts and drives the connecting block 104 to move toward the display screen body 2. The connecting block 104 will drive the positioning piece 106 to move toward the display screen body 2. When the positioning piece 106 contacts the display screen body 2 and the positioning piece 106 contacts the positioning rod 107, the display screen body 2 will be restricted. Therefore, when the operator touches and operates the display screen body 2, the display screen body 2 will not move with it, thereby facilitating the operator to use the display screen body 2.

[0039] Please refer to Figure 7, shown is a second embodiment of the present invention, which, based on the first embodiment, also includes: a shielding component 11, the shielding component 11 includes an outer plate 111 fixedly connected to the side wall of the installation frame 1, an inner plate 112 arranged on a side of the outer plate 111 close to the bottom wall of the installation frame 1, and a through hole 113 formed in the middle of the outer plate 111 and the inner plate 112 in sequence; a buffer strip 114 is arranged at the through hole 113 of the inner plate 112, and the buffer strip 114 and the inner plate 112 are made of soft material.

[0040] Among them, the shielding assembly 11 is used to increase the aesthetics of the shock-resistant vehicle-mounted display screen, prevent people from viewing the structure inside the installation frame 1, and the shielding group also improves safety to prevent the operator's fingers from getting stuck in the installation frame 1 and causing damage; it can be understood that the outer plate 111 is made of a hard material to provide support for the entire shielding assembly 11, and the inner plate 112 is made of a soft material, which is a rubber material in this embodiment, and there is a gap between the inner plate 112 and the display screen body 2. When the display screen body 2 shakes violently and moves forward, the display screen body 2 will contact the inner plate 112, so that the inner plate 112 is made of rubber material, which can protect the display screen body 2. The through hole 113 is used for the operator to pass through the through hole 113 to operate the display screen body 2. The buffer bar 114 is arranged on the inner plate 112 and protrudes toward the direction of the display screen body 2. When the display screen body 2 moves forward, the display screen body 2 contacts the buffer bar 114, thereby making the buffer bar 114 contact the buffer bar 114 in a small range, thereby further protecting the display screen body 2.
