Description

Technical Field

[0001] The utility model relates to the technical field of televisions, in particular to a wall-mounted device for an in-vehicle television. Background Art

[0002] With the progress of technology and people's pursuit of mobile living quality, recreational vehicles have become the travel choice of more and more people. A television is also installed in the recreational vehicle to facilitate consumers to enjoy viewing and entertainment when traveling.

[0003] Among them, in order to facilitate the wall-mounted installation of the television, the traditional television usually has nuts for inlaid installation on the rear shell. When the rear shell is injection-molded, the nuts are placed in the slots designed on the rear shell, so that the plastic wraps the nuts. However, this design still has the following problems in actual application:

[0004] First of all, the combination of the plastic and the nut may not be firm enough, resulting in the nut being easily loosened or detached during the production process or after being used for a period of time. The molding process of the plastic may generate stress on the nut, making it more likely to have problems in subsequent use and easily causing the problem of insecure installation. When installing the wall mount, if too much torque is applied, it may have a negative impact on this nut design. Due to the limited elasticity and load-bearing capacity of the plastic, excessive torque may cause the plastic to crack or deform, thus affecting the fastening effect of the nut. This may lead to the television being insecurely installed, increasing the risk of the television falling. In addition, the large torque may also cause the nut itself to slip or be damaged between the rear shell, affecting the stability of the nut, and at the same time causing the screw to be unable to be fixed tightly and having the risk of detachment, further reducing the reliability of the wall-mounted installation connection of the television. If this traditional television is installed in a long-term mobile use scenario, such as inside a recreational vehicle, during the driving process of the recreational vehicle, the vibration and bump generated may also affect the nut wrapped by the plastic. The long-term vibration and bump may cause the plastic to fatigue and gradually crack or loosen. This may lead to a decrease in the fastening force of the nut, affecting the stability and safety of the television installation. In addition, the vibration and bump of the recreational vehicle may also cause the friction between the nut and the plastic to decrease, increasing the risk of slipping. This design does not have adaptability in a mobile environment and is only suitable for use in a static environment. Moreover, when the television is installed on a mobile mount and the television is adjusted during movement, the nut may be subjected to additional impact force or torque, easily resulting in loosening or damage.

[0005] Furthermore, at different ambient temperatures, the performance of the plastic may change. High temperature may make the plastic soft, reducing its load-bearing capacity and fastening effect. Low temperature may make the plastic brittle and more likely to crack. These temperature changes may cause the nut to loosen or the connection to be unstable, and also pose a risk of the television falling off during installation in the recreational vehicle, thus affecting the normal use of the television.

[0006] Therefore, there is an urgent need for a vehicle-mounted TV wall-mounting device to overcome the above-mentioned problems. Contents of utility model

The structure is more firm and stable and more convenient to use.

[0034] Combined with the attached drawings, the assembly principle of the in-vehicle TV wall-mounted device 100 of the present utility model will be described in detail:

[0035] First, the metal fixing plate 20 is clamped and positioned on the front side of the rear shell 10, such that the positioning and clamping wall 21 is clamped between two adjacent first reinforcing ribs 12 from front to back, and the rear end of the connecting column body 30 is clamped and positioned within the corresponding annular clamping step 16. Then, the first bolts 40 are respectively passed through the corresponding first mounting holes 22 and threadedly fastened into the corresponding second internal threads 141, so that the metal fixing plate 20 is fixedly connected to the front side of the rear shell 10.

[0036] Then, the rear side connecting plate 50 is butted against the rear side of the rear shell 10, such that the second mounting holes 51 are correspondingly and directly opposed and communicated with the corresponding avoiding holes 11 in the front-back direction. Then, the second bolts 60 are sequentially passed through the correspondingly communicated second mounting holes 51 and avoiding holes 11 from back to front and threadedly fastened into the corresponding first internal threads 31, so that the rear side connecting plate 50 is fixedly connected to the rear side of the rear shell 10.

[0037] Next, the adjustment connecting arm 70 is connected and mounted on the connecting seat 52. Then, the rear end of the first swing arm 90a is swingably connected to the front side of the mounting seat 80. Then, the rear end of the second swing arm 90b is swingably connected to the front end of the first swing arm 90a. Then, the front end of the second swing arm 90b is swingably connected to the third mounting hole, thus completing the assembly operation of the in-vehicle TV wall hanging device 100 of the present utility model.

[0038] Since the metal fixing plate 20 of the in-vehicle TV wall-mounted device 100 of the present utility model is fixedly connected to the front side of the rear case 10, the connecting columns 30 are integrally and fixedly connected to the rear side of the metal fixing plate 20 along the front-rear direction. Avoidance holes 11 corresponding to the connecting columns 30 one by one are formed on the rear case 10. First internal threads 31 are formed in the connecting columns 30, and the first internal threads 31 are correspondingly and directly communicated with the corresponding avoidance holes 11 along the front-rear direction. Then, by fixing the metal fixing plate 20 on the rear case 10 and integrally and fixedly connecting the connecting columns 30 to the metal fixing plate 20, the combination between the metal fixing plate 20 and the connecting columns 30 is more firm and stable, and the wall-mounted installation can be realized through the first internal threads 31 formed in the connecting columns 30.

The high strength and stability of the metal fixing plate 20 ensure the reliability of the connection of the rear case 10, and the metal fixing plate 20 has a higher torque-bearing capacity. When installing the wall mount, even if excessive torque is applied, it will not cause significant damage to the metal fixing plate 20, thereby reducing the risk of plastic cracking or deformation and avoiding affecting the installation fastening effect. The strengthening structure of the metal fixing plate 20 fixed on the rear case 10 has a firm structure that ensures the firmness of the wall-mounted installation and reduces the risk of the TV falling. In addition, the durability of the metal fixing plate 20 enables it to better withstand strong torque, avoiding the occurrence of thread stripping or damage, and further improving the reliability of the installation connection. The metal fixing plate 20 has stronger anti-vibration and bumping capabilities. During the driving of the RV, the vibration and bumping have less impact on the metal fixing plate 20, reducing the possibility of plastic fatigue and cracking. The firm structure of the metal fixing plate 20 can reliably maintain the fastening force of the installation connection, ensuring the stability and safety of the TV in the mobile environment, and also reducing friction and the risk of thread stripping. The strengthening structure of using the metal fixing plate 20 fixed on the rear case 10 enables the TV to better adapt to the mobile environment. When the TV is installed on a mobile wall mount and the TV is adjusted by stretching during movement, the metal fixing plate 20 can effectively withstand additional impact force or torque, significantly reducing the possibility of loosening or damage. Moreover, the metal fixing plate 20 has more excellent temperature stability compared with plastic. Under different ambient temperatures, the performance of the metal fixing plate 20 changes little, and it can maintain good bearing capacity and fastening effect. Whether in a high-temperature or low-temperature environment, the metal fixing plate 20 can ensure the stability of the installation female connection, is not easily separated from or damaged by the rear case 10, is not affected by temperature changes, and avoids loosening or connection instability problems caused by temperature, further improving the installation firmness, stability and durability of the TV in the RV.
