[0031] Example 1

[0032] like Figures 1 to 6 The figure shows a multimedia device support device of embodiment 1 of the present invention, including a track mechanism 2, a support mechanism 5 and a connecting rod mechanism 6. The track mechanism 2 is arranged on the top 1 of the carrier, and the support mechanism 5 is used to fix the multimedia device. The front end of the support mechanism 5 is slidably connected to the track mechanism 2, and the rear end of the support mechanism 5 is hinged to the connecting rod mechanism 6, and the connecting rod mechanism 6 is slidably connected to the track mechanism 2; when the multimedia device is used, the support mechanism 5 slides forward to a predetermined position of the track mechanism 2, and the front end of the support mechanism 5 is separated from the track mechanism 2 and rotated downward to open to various angles. When the multimedia device is not in use, the support mechanism 5 slides backward to leave the predetermined position, and the front end of the support mechanism 5 is rotated upward and retracted into the track mechanism 2. When the support mechanism 5 rotates, the connecting rod mechanism 6 is synchronously deformed.

[0033] The multimedia device support device in this embodiment is applicable to vehicles other than vehicles, and can also be applied to vehicles such as ships and airplanes. The multimedia devices can be displays, speakers, game consoles, lighting equipment, office equipment, and other equipment. Multimedia device support devices of different sizes can be installed at different locations in the vehicle to carry multimedia devices of different sizes to meet the viewing needs of different passengers.

[0034] like Figure 2 , Figure 3 As shown, the track mechanism 2 includes a left track and a right track symmetrically arranged on the left and right sides of the support mechanism 5, and a parallel first guide groove 205 and a second guide groove 204 are arranged in the left track and the right track. The first guide groove 205 is located above the second guide groove 204, the front end of the support mechanism 5 is slidably connected to the second guide groove 204, and the connecting rod mechanism 6 is slidably connected to the first guide groove 205 and the second guide groove 204.

[0035] In order to improve the structural strength of the track mechanism 2, a front beam 3 and a rear beam 4 can also be set. The front beam 3 connects the front ends of the left track and the right track, and the rear beam 4 connects the rear ends of the left track and the right track. When the multimedia equipment support device is installed on the top of the vehicle, it can be installed and fixed through the left track, the right track, the front beam 3 and the rear beam 4 at the same time.

[0036] Preferably, the left rail, the right rail, the front beam 3 and the rear beam 4 can all be made of sheet metal.

[0037] The second guide groove 204 is provided with a notch 201 facing downward, and the front end of the supporting mechanism 5 can be separated from the track mechanism 2 through the notch 201 .

[0038] A guide block 202 is provided in both the left track and the right track. The guide block 202 is provided behind the notch 201. A gradually rising third guide groove 203 is provided in the guide block 202. The third guide groove 203 is connected with the second guide groove 204. When the connecting rod mechanism 6 slides to the guide block 202, the front end of the support mechanism 5 slides to the notch 201. During the opening and retracting of the support mechanism 5, the connecting rod mechanism 6 is deformed at the same time with the help of the third guide groove 203. The third guide groove 203 and the second guide groove 204 can be made in one piece.

[0039] like Figure 4 , Figure 5 , Figure 6 As shown, the support mechanism 5 includes a bracket 501, and the multimedia device is fixed in the bracket 501. A connecting plate 503 and a first slide foot 504 are provided on the left and right sides of the bracket 501. The first slide foot 504 is located at the front end of the bracket 501, and the connecting plate 503 is located at the rear end of the bracket 501. The connecting plate 503 is hinged to the connecting rod mechanism 6, and the first slide foot 504 slides in the second guide groove 204, and can be detached from the groove 201 when sliding to the groove 201.

[0040] For the convenience of manufacturing, side strips 502 are provided on both sides of the bracket 501 . The side strips 502 are L-shaped, and the connecting plate 503 and the first sliding foot 504 are provided on the side strips 502 .

[0041] The bracket 501 is U-shaped as a whole, and the side strip 502 and the bracket 501 can be welded or bolted, or can be made in one piece. The connecting plate 503 is made in one piece with the side strip 502. The bracket 501 and the side strip 502 can both be made by sheet metal stamping, for example, stamped separately or stamped in one piece.

[0042] Preferably, the first sliding foot 504 is made of a self-lubricating material, such as a polymer material.

[0043] like Figure 4 , Figure 5As shown, the connecting rod mechanism 6 includes a first support rod 601, a connecting plate 503, a second support rod 602 and a third support rod 603, the connecting plate 503 is externally connected to the multimedia device to be rotated, the first end of the first support rod 601 is hinged to the first end of the connecting plate 503, the second end of the connecting plate 503 is hinged to the first end of the second support rod 602, the second end of the second support rod 602 is hinged to the first end of the third support rod 603, the second end of the third support rod 603 is hinged to the second end of the first support rod 601, the first support rod 601 remains horizontal and motionless, the connecting plate 503, the second support rod 602 and the third support rod 603 rotate synchronously, and the connecting plate 503 drives the multimedia device to rotate. The first support rod 601, the connecting plate 503, the second support rod 602 and the third support rod 603 form a deformable mechanism.

[0044] Preferably, the length of the first support rod 601 is greater than the length of the connecting plate 503, the second support rod 602 and the third support rod 603, because the connecting plate 503, the second support rod 602 and the third support rod 603 are suspended on the first support rod 601. Increasing the length of the first support rod 601 is beneficial to improving structural strength and operational stability.

[0045] The lower edge of the first support rod 601 may be designed to be arc-shaped to facilitate connection with the third support rod 603 .

[0046] Preferably, the second support rod 602 is arc-shaped. During the deformation of the connecting rod mechanism 6, the second support rod 602 will never protrude downward from the left track or the right track. The overall height of the connecting rod mechanism 6 remains unchanged and will not collide with other objects, making it convenient to use in the vehicle.

[0047] The third support rod 603 is triangular in shape, and a second slide foot 604 is provided at the third end of the third support rod 603. The second slide foot 604 slides in the second guide groove 204. When sliding into the third guide groove 203, the front end of the support mechanism 5 disengages from the track mechanism 2 and rotates downward to open to various angles. When the second slide foot 604 leaves the third guide groove 203, the front end of the support mechanism 5 rotates upward and retracts into the track mechanism 2.

[0048] Preferably, the third support rod 603 includes two triangular plates, and the hinged positions of the third support rod 603, the first support rod 601 and the second support rod 602 are arranged in the two triangular plates. With this design, the structural strength and operational stability of the connecting rod mechanism 6 can be significantly improved.

[0049] The first support rod 601 is provided with a third sliding foot 605 and a fourth sliding foot 606 , and the third sliding foot 605 and the fourth sliding foot 606 slide in the first guide groove 205 .

[0050] Preferably, the third sliding foot 605 and the fourth sliding foot 606 are made of self-lubricating material, such as polymer material.

[0051] The first support rod 601 is provided with a limiting plate 607 bent outwards. The limiting plate 607 slides in the first guide groove 205 . The third sliding foot 605 and the fourth sliding foot 606 are respectively provided at the front and rear sides of the limiting plate 607 .

[0052] The limit plate 607 is connected to a driving device, such as a motor, through a flexible shaft. The flexible shaft can be a steel wire rope. The motor drives the connecting rod mechanism 6 and the supporting mechanism 5 to slide. When controlled, the supporting mechanism 5 can be automatically opened and retracted. In addition, the stability of the system can be further enhanced by limiting the position of the limit plate 607 and the first guide groove 205.

[0053] Example 2

[0054] In this embodiment, different from the embodiment 1, the second guide groove 204 is not provided with the notch 201 , and the front end of the support mechanism 5 is in a suspended state and is not arranged in the second guide groove 204 .

[0055] The multimedia device and the supporting mechanism 5 are completely supported by the connecting plate 503 , and the structural strength of the connecting plate 503 needs to be large enough to meet the design requirements.

[0056] When the connecting rod mechanism 6 slides to the third guide groove 203, it can be deformed with the help of the third guide groove 203, and the support mechanism 5 performs an opening action at the same time. When the connecting rod mechanism 6 leaves the third guide groove 203, the support mechanism 5 performs a retracting action at the same time.

[0057] By adopting the design solution in this embodiment, the structure of the multimedia equipment supporting device can be simplified.

[0058] Example 3

[0059] In this embodiment, the difference from the embodiment 1 or the embodiment 2 is that the structures of the left track and the right track in the track mechanism 2 are different, and any one of the tracks is provided with a parallel first guide groove 205 and a second guide groove 204 (and a third guide groove 203 is required). Only one guide groove is required in the other track, and either the first guide groove 205 or the second guide groove 204 can be provided, and the third guide groove 203 is not required.

[0060] At this time, the left and right side structures of the support mechanism 5 are also different. The corresponding track mechanism 2 is provided with a first guide groove 205 and a second guide groove 204. The rear end of the support mechanism 5 is hinged to the connecting rod mechanism 6, and the connecting rod mechanism 6 is slidably connected to the track mechanism 2.

[0061] Corresponding to the track mechanism 2 in which only one guide groove is provided, the rear end of the support mechanism 5 is connected to a simplified connecting rod mechanism, and the simplified connecting rod mechanism is slidably connected to the track mechanism 2 .

[0062] For example, when only the first guide groove 205 is provided, the simplified linkage mechanism only retains the first support rod 601 and the connecting plate 503 . The first support rod 601 is slidably connected to the first guide groove 205 and is hinged to the connecting plate 503 , which still meets the rotation requirement of the support mechanism 5 .

[0063] When only the second guide groove 204 is provided, the simplified connecting rod mechanism only retains the second support rod 602 and the connecting plate 503 . The second support rod 602 is slidably connected to the second guide groove 204 and is hinged to the connecting plate 503 , which still meets the rotation requirement of the support mechanism 5 .

[0064] By adopting the design solution in this embodiment, the structure of the multimedia equipment supporting device can be simplified.

[0065] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.
