The fixing member 10 is located at the top of a whole of the display device holder 100 for mounting the display device holder 100 on a mounting surface 20 of an object. The fixing member 10 includes a first end 101 connected to the supporting member 30 and a second end 103 opposite to the first end 101. The fixing member 10 further includes a first position-limiting wall 13, a fixing plate 11 and a second position-limiting wall 15 which are connected in sequence. The fixing plate 11 is configured to directly contact with the mounting surface 20, and is roughly of an I-shaped flat plate. The fixing plate 11 is formed with a plurality of mounting holes, and the fixing plate 11 is fixed to the mounting surface 20 by screw mounting. The mounting surface 20 may be a wall, a ceiling, a roof of a recreational vehicle, a cupboard and the like. It can be understood that the fixing plate 11 may also be of other shapes that are conducive to improving stability of mounting, and may be set in different shapes according to actual needs. The first position-limiting wall 13 and the second position-limiting wall 15 are arranged opposite to each other on two sides of the fixing plate 11 in a width direction, and are respectively bent and extended towards the supporting member 30. The second position-limiting wall 15 is parallel to the first position-limiting wall 13. The first position-limiting wall 13, the fixing plate 11, and the second position-limiting wall 15 cooperatively form a sliding groove 16 for storing a locking device 17.
The locking device 17 is slidably arranged at a position close to the second end 103 of the sliding groove 16. The locking device 17 is configured to lock the supporting member 30 when the supporting member 30 is in a folded state. The locking device 17 includes a main body 171, a position-limiting rod 173, an elastic member 175 and a triggering member 174. The main body 171 is movably mounted to the first position-limiting wall 13 and the second position-limiting wall 15 of the fixing member 10, such that the main body 171 can move back and forth along a length direction of the fixing member 10, to release and hold the supporting member 30. A holding portion 176 is formed on a side, close to the second end 103, of the main body 171. The main body 171 includes two opposite side walls, and a pair of position-limiting holes 172 which are parallel to each other are disposed in each of the two side walls. The position-limiting holes 172 are set to be in an oval shape, and the width is the same as the diameter of the position-limiting rod 173 for the position-limiting rod 173 to pass through. The position-limiting rod 173 is arranged to penetrate through the first position-limiting wall 13, the position-limiting holes 172 and the second position-limiting wall 15, and two ends of the position-limiting rod 173 are fixed to the first position-limiting wall 13 and the second position-limiting wall 15. The main body 171 is movably mounted to the fixing member 10 by the position-limiting rod 173, and the main body 171 moves relative to the position-limiting rod 173 by the position-limiting holes 172.
In the present embodiment, two position-limiting rods 173 are arranged, and the corresponding position-limiting holes 172 are in two pairs, but one or more than two position-limiting holes 172 can be arranged according to actual needs.
It can be appreciated that two position-limiting protrusions 177 are arranged on each of the position-limiting rods 173. One position-limiting protrusion 177 is held between the first position-limiting wall 13 and the main body 171, and the other position-limiting protrusion 177 is held between the second position-limiting wall 15 and the main body 171, such that the two position-limiting protrusions 177 prevent the main body 171 from shaking leftwards and rightwards between the first position-limiting wall 13 and the second position-limiting wall 15.
The elastic member 175 is mounted between the position-limiting rod 173 and the main body 171. One end of the elastic member 175 is connected to the position-limiting rod 173, and the other end of the elastic member 175 is connected to a side, away from the position-limiting rod 173, of the main body 171. When the user pulls the triggering member 174, the main body 171 moves relative to the position-limiting rod 173, the elastic member 175 is then compressed. When the user releases the triggering member 174, the main body 171 moves back, the main body 171 is then reset under a reset force of the elastic member 175.
The elastic member 175 may be a spring, an elastic cord, etc., and the position-limiting rod 173 may be a bolt, a screw, etc.
The holding portion 176 is arranged on a side, away from the supporting member 30, of the locking device 17, and is a concave portion which is concave inwards. The holding portion 176 is formed with a receiving groove 1761 on the side away from the triggering member 174, and the receiving groove 1761 is configured to engaging with the supporting member 30. The bottom surface of the holding portion 176 is provided with a guiding inclined surface 1763, and the guiding inclined surface 1763 is located on a side, away from the fixing member 10, of the receiving groove 1761.
The triggering member 174 wraps around the main body 171 and extends out of the fixing member 10, thereby facilitating easy operation of the triggering member 174 by the user.
The supporting member 30 is of a long-strip structure, i.e., the supporting member 30 is long cylindrical-shaped or cuboid-shaped. The supporting member 30 includes a first rod portion 32, a second rod portion 33 wrapping around the first rod portion 32, and a retaining screw 34. The first rod portion 32 may be a hollow-shaped structure, and a first fixing hole 321 which penetrates through the first rod portion 32 is arranged close to the fixing member 10. The second rod portion 33 is also of a hollow-shaped structure, and a plurality of second fixing holes 331 are arranged at intervals along a length direction of the rod. The second fixing holes 331 penetrate through the second rod portion 33. The first rod portion 32 can slide relative to the second rod portion 33. A relative positional relationship between the first rod portion 32 and the second rod portion 33 may be adjusted when the first rod portion 32 slides relative to the second rod portion 33. Therefore, the first fixing hole 321 may be matched with any one of the second fixing holes 331 by the sliding of the first rod portion 32 and may be fixed by the retaining screw 34. When the first fixing hole 321 matches the second fixing hole 331 closest to the fixing member 10, the supporting member 30 is at its minimum length. When the first fixing hole 321 matches the second fixing hole 331 closest to the connecting member 50, the supporting member 30 is at its maximum length, i.e., the supporting member 30 is of a retractable structure.
A connecting portion 31 is arranged at a position, away from the fixing member 10, of the supporting member 30, and the connecting portion 31 is provided with a locking member 311, and the locking member 311 is connected to the supporting member 30. When the display device holder 100 is in the folded state, the supporting member 30 is substantially parallel to the fixing member 10, and when the connecting portion 31 is attached to the fixing member 10, the locking member 311 is held in the holding portion 176. Therefore, the supporting member 30 can be stably hovered in a horizontal position without falling off.

When the display device holder 100 is in the folded state, the locking device 17 is in a first position A. The first position A is configured such that the locking member 311 can be clamped into the holding portion 1761, as shown in
When the display device holder 100 is in the unfolded state, the locking device 17 is in the second position. The user forcefully pushes the supporting member 30 towards the fixing member 10, and the supporting member 30 rotates relative to the fixing member 10 and moves close to the fixing member 10. Meanwhile, the locking member 311 contacts with the guiding inclined surface 1763 and moves along the guiding inclined surface 1763 towards the receiving groove 1761, meanwhile, the main body 171 is pushed by the supporting member 30 to compress the elastic member 175. When the connecting portion 31 is close to the receiving groove 1761, the main body 171 moves relative to the fixing member 10 under the elastic restoring force of the elastic member 175, such that the locking member 311 is clamped into the receiving groove 1761.

The adjustment methods of the connecting member 50 of the present embodiment are described below. In the first adjustment method, the locking bolt 511 is loosened. An adjusting space is created between the fastener 51 and the supporting member 30, such that the fastener 51 can be adjusted by 360° relative to the supporting member 30. After the fastener 51 is adjusted to a corresponding angle, the locking bolt 511 is locked, and the display device can rotate horizontally by 360°. In the second adjustment method, the first bolt 52 is loosened. A small degree of adjustment of the pitching angle can be achieved by changing the position of the first bolt 52 in the arc-shaped first hole 531. The first bolt 52 is locked after adjustment to a corresponding angle, that is, the pitching angle of the display device in a vertical direction can be adjusted. In the third adjustment method, the second bolt 532 is loosened. The second bolt 532 changes its position in the second hole 533 to drive the mounting member 70 to rotate. After the mounting member 70 rotates to a corresponding angle, the second bolt 532 is locked, that is, the display device can be switched between the horizontal, vertical and oblique screens.
The above three adjustment methods can be completed independently, or a combination of two or three adjustment methods can be completed, such that the display device holder can be located in a variety of different angles, and the viewing experience is enriched.
In summary, as to the display device holder 100 of the present embodiment, the locking member 311 is held by the holding portion 176 under the folded state, and the supporting member 30 will not loosen and fall off, and can cope with motion scenarios such as recreational vehicles and earthquakes. The supporting member 30 can be released by pulling the triggering member 174, and can be changed from the folded state to the unfolded state, with such advantages of safety and stability, and easy operation. In addition, by means of adjusting parts such as the hinge mechanism 14, the locking bolt 511, the first bolt 52, the second bolt 532 and the like, the display device can be used at different angles and can adapt to a variety of scenarios, thereby improving the comfort of the user in the using process.
