[0064] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0065] See also Figure 1 The display device bracket 100 involved in this embodiment is installed on a fixed object (not shown) such as a caravan, a ceiling, or a wall. The display device bracket 100 includes a fixed plate 10 fixedly connected to the fixed object, a mounting plate 50 for mounting the display device, and a rotating arm 30 rotatably connected between the fixed plate 10 and the mounting plate 50. Specifically, one side of the fixed plate 10 is attached to the fixed object, and the other side is rotatably connected to one end of the rotating arm 30, and the other end of the rotating arm 30 is rotatably connected to the mounting plate 50, so that the fixed plate 10, the rotating arm 30, and the mounting plate 50 are connected in sequence.

[0066] The fixing plate 10 is in the shape of a rectangular plate, and fixing holes 13 are evenly opened at different positions of the fixing plate 10. Screws are passed through the fixing holes 13 to fix the fixing plate 10 to the fixed object. A group of opposite positioning blocks 15 are arranged in the middle of the fixing plate 10, and the positioning blocks 15 are arranged on both sides of the width direction of the fixing plate 10. Figure 5 When the display device bracket 100 is in the folded state, the top surface of the blocking block 15 contacts the rotating arm 30, thereby limiting the rotating arm 30 from rotating toward the side close to the fixed plate. The function of the blocking block 15 is to ensure that the display device is in a horizontal state in the folded state to improve the user experience. Therefore, the height of the blocking block 15 is the distance between the rotating arm 30 and the fixed plate 10 when the rotating arm 30 is parallel to the fixed plate 10.

[0067] See also Figure 1In this embodiment, two groups of mounting pieces 17 are formed by protruding and extending from a side of the fixing plate 10 away from the wall, and the two groups of mounting pieces 17 are respectively protruding and arranged at both ends of the fixing plate 10, and the number of mounting pieces 17 is such that the plane of the mounting piece 17 is perpendicular to the fixing plate 10. Each group of mounting pieces 17 has two mounting pieces, and each group of mounting pieces 17 is arranged at intervals in the length direction of the fixing plate 10 to form a rotation space 173, and the rotation space 173 is used to connect the rotating arm 30 and allow the rotating arm 30 to rotate in the rotation space 173. It can be understood that the number of mounting pieces 17 is not limited and is determined according to actual needs.

[0068] See also Figure 1 and Figure 4 , a locking device 11 is provided on at least one side of the fixed plate 10, and the locking device 11 is composed of a locking member 110 and an elastic mechanism 114. The locking member 110 includes a connecting rod 113, and a first locking rod 111 and a second locking rod 112 vertically extending from opposite ends of the connecting rod 113. Specifically, the first locking rod 111 is installed in parallel to the fixed plate 10, the connecting rod 113 is vertically bent and extended from one side of the first locking rod 111 away from the positioning block 15, and the second locking rod 112 is vertically bent and extended from the other side of the connecting rod 113 away from the first locking rod 111. The first locking rod 111, the connecting rod 113 and the second locking rod 112 are connected in sequence, and the first locking rod 111 and the second locking rod 112 are relatively parallel and spaced apart, so as to form a U-shaped groove 117. A group of mounting plates 17 close to the locking device 11 are located in the U-shaped groove 117, and the plane of the mounting plates 17 is parallel to the connecting rod 113. When the pulling member 116 is not pulled, the connecting rod 113 contacts the mounting plate 17, so that the mounting plate 17 restricts the moving member from moving toward the opening direction of the U-shaped groove 117. It is understood that the locking device 11 can be arranged at other positions of the fixing plate 10. It is understood that the number of the locking devices 11 can be multiple.

[0069] See also Figure 4The elastic mechanism 114 includes a first limiting plate 1141 close to the connecting rod 113, a second limiting plate 1142 arranged opposite to the first limiting plate 1141, and an elastic member 1143 and a push plate 1144 located between the first limiting plate 1141 and the second limiting plate 1142. The push plate 1144 is fixedly connected to the first locking rod 111 and the second locking rod 112. In this embodiment, the first limiting plate 1141 and the second limiting plate 1142 are provided with corresponding limiting holes (not shown in the figure), and one end of the first locking rod 111 and the second locking rod 112 passes through the limiting holes of the first limiting plate 1141, the elastic member 1143, the push plate 1144 and the limiting holes of the second limiting plate 1142, respectively, and protrudes from the limiting holes of the second limiting plate 1142 to the outside of the second limiting plate 1142, so that the first locking rod 111 and the second locking rod 112 are movably installed in the elastic mechanism 114. The first limiting plate 1141 and the second limiting plate 1142 limit the locking rods 111 and 112 up and down, so that the locking rods 111 and 112 can only slide horizontally. The first locking rod 111 and the second locking rod 112 are respectively provided with an elastic mechanism 114 and fixedly sleeved with a push plate 1144 that can move relative to the second limiting plate 1142. One end of the elastic member 1143 close to the connecting rod 113 is fixedly connected to the first limiting plate 1141, and the other end is fixedly connected to the push plate 1144, and the push plate 1144 drives the elastic member 1143 to move.

[0070] The working principle of the locking device 11 is described below.

[0071] When the locking device 11 needs to be unlocked, the pulling member 116 is pulled, and the pulling member 116 drives the locking device 11 to move relative to the fixed plate 10, and the first locking rod 111 and the second locking rod 112 drive their respective pushing plates 1144 to move together in a direction away from the locking block 15. At this time, one end of the elastic member 1143 connected to the pushing plate 1144 moves along with the pushing plate 1144, and the other end is fixedly connected to the first limiting plate 1141, so that the elastic member 1143 is pushed by the pushing plate 1144 and moves toward the first limiting plate 1141, so that the elastic member 1143 is compressed between the pushing plate 1144 and the first limiting plate 1141, and the locking device 11 is in an unlocked state. When the pulling member 116 is released, the elastic member 1143 loses its pulling force and rebounds under the elastic force, driving the locking device 11 to move until the pushing plate 1144 is abutted by the second limiting plate 1142 and the locking device 11 returns to its original position, reaching a locked state.

[0072] See also Figure 1 and Figure 2The rotating arm 30 is connected between the fixed plate 10 and the mounting plate 50, and includes a front arm 31, a crossbar 33 and a rear arm 32 connected in sequence. The rear arm 32 is a double-arm structure, which includes a first support arm 321 and a second support arm 322 arranged in parallel. One end of the first support arm 321 and the second support arm 322 is accommodated between a group of mounting plates 17. In a group of mounting plates 17, a first through hole (not shown) is penetrated through the side wall of one of them, and a second through hole 171 corresponding to the first through hole is penetrated on the other mounting plate 17. The first support arm 321 is located between two mounting plates 17 in the first group of mounting plates 17, and the second support arm 322 is located between two mounting plates 17 in the second group of mounting plates 17. Two first shaft pins 175 respectively pass through the second through hole 171 of a group of mounting plates 17 and the first through holes of the corresponding support arms 321 and 322, so that the mounting plates 17 and the support arms 321 and 322 are rotatably connected together. Thus, the rotating arm 30 can rotate relative to the fixed plate 10. A third through hole (not shown) is formed through the other end of the first support arm 321 and the second support arm 322, and the cross bar 33 passes through the third through hole, so that the cross bar 33 is rotatably connected with the first support arm 321 and the second support arm 322. The middle part of the cross bar 33 extends to form a forearm 31, and the forearm 31 can be driven to rotate through the cross bar 33. A receiving space 323 is formed between the first support arm 321 and the second support arm 322 for receiving the forearm 31. Specifically, the forearm 31 is a single-arm structure, and the forearm 31 and the rear arm 32 are a telescopic structure. The forearm 31 can be telescoped and received in the receiving space 323, which increases the stability of the overall structure, improves the reliability of the structure, and the forearm 31 and the rear arm 32 of the display device bracket 100 are folded, thereby improving portability.

[0073] In this embodiment, at least one wire clip 37 is disposed on the first support arm 321 , the second support arm 322 and the forearm 31 . The wire clip 37 is used to prevent the wires of the display device from being routed and entangled, which is more convenient.

[0074] See also Figure 2 and Figure 3The mounting plate 50 is composed of a back plate 51 for directly fixing the display device, a connecting seat 55 connected to the forearm 31, and an adjustment seat 53 located between the connecting seat 55 and the back plate 51. The end of the forearm 31 away from the cross bar 33 is rotatably connected to the adjustment seat 55. The connecting seat 55 includes a platform surface 551 parallel to the fixing plate 10, and two clamping surfaces 553 extending vertically from both ends of the platform surface 551 to the side close to the rotating arm 30. A fourth through hole 5531 is formed on the two clamping surfaces 553, one end of the forearm 31 is clamped between the two clamping surfaces 553, and a fifth through hole (not shown) is opened. The second shaft pin 5533 passes through the fourth through hole 5531 of the clamping surface 553 and the fifth through hole of the forearm 31, so that the mounting plate 50 and the rotating arm 30 are rotatably connected together. At least one of the two clamping surfaces 553 extends vertically outward to form a locking plate 555 . The locking plate 555 is used to cooperate with the locking device 40 to lock the display device bracket 100 to prevent shaking.

[0075] One end of the adjustment seat 53 is connected to the connecting seat 55 by a screw, and the other end extends to the side close to the rotating arm to form a group of waist holes 531, and the waist holes 531 are arc-shaped long holes. The waist hole screws 533 pass through the waist holes 531 and the connecting seat 55, so that the adjustment seat 53 and the connecting seat 55 are connected together. The waist hole screws 533 can slide along the edges of both sides in the arc-shaped waist hole 531, thereby driving the adjustment seat 53 to rotate slightly up and down relative to the connecting seat 55, so as to achieve the up and down adjustment of the display device. It can be understood that the shape of the waist hole 531 can be different shapes.

[0076] The side of the back plate 51 close to the waist hole 531 is tilted downward to form a snap-in bevel 511, and the upper plane edge of the waist hole 531 of the adjustment seat 53 is formed with a notch 535 corresponding to the snap-in bevel 511. When the back plate 51 and the adjustment seat 53 are in contact, the snap-in bevel 511 snaps into the notch 535, so that the back plate 51 and one end of the adjustment seat 53 are connected together. The above is a connection method between the back plate 51 and the adjustment seat 53, which is used to enhance the stability of the connection of the back plate 51 and improve the load-bearing capacity. It can be understood that the connection of the back plate 51 is not limited to this method, and it can be a variety of methods such as screws and magnetic suction.

[0077] The folding and self-locking process of the display device bracket 100 is introduced below.

[0078] like Figure 1As shown, the mounting plate 50 is parallel to the fixed plate 10, and the rotating arm 30 is perpendicular to the fixed plate 10 and the mounting plate 50. At this time, the display device bracket 100 is in a fully unfolded state. When folding, the user first rotates the mounting plate 50, and the connecting seat 55 rotates relative to the rotating arm 30 until the mounting plate 50 is parallel to the forearm 31 of the rotating arm 30. Then push the forearm 31 or the crossbar 33, so that the crossbar 33 rotates and drives the forearm 31 to rotate until the forearm 31 is nested and accommodated in the accommodating space 35 and the forearm 31 and the rear arm 32 are located in the same plane, that is, the forearm 31 does not protrude from the rear arm 32. At this time, the mounting plate 50, the forearm 31 and the rear arm 32 are parallel to each other and are perpendicular to the fixed plate 10. Then, the user pulls the pulling member 116 to move the locking device 11 to the side close to the pulling member 116. While holding the pulling member 116, the rear arm 32 is rotated to one of the two sides until the front arm 31 contacts the locking block 15, and the locking plate 555 comes to the lower part of the first locking rod 111 and the second locking rod 112 before moving. The pulling member 116 is released, and the locking device 11 returns to its original position, so that the first locking rod 111 and the second locking rod 112 lock the locking plate 555. Figure 5 As shown, at this time, the fixed plate 10, the rotating arm 30 and the mounting plate 50 are parallel to each other, completing the folding and self-locking.

[0079] The display device bracket 100 of this embodiment has a double-rod locking structure composed of a first locking rod 111 and a second locking rod 112. Compared with the traditional display device bracket 100 without self-locking function or single-element self-locking, the locking range is larger and the locking is more stable. When used in application scenarios such as RVs, the display device bracket 100 of this embodiment can bring users a better use experience.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
