[0002] In the rehabilitation room of a mental hospital, there is a wall-mounted television hanging on the wall to play television images for mental patients. However, due to the particularity of mental illness, patients often smash the television.

[0003] Based on the above situation, medical staff often install protective covers on TV screens in rehabilitation rooms to reduce the impact force when mentally ill patients hit or smash the TV. However, since the protective cover is directly installed on the screen, the force received by the protective cover will still be transmitted to the screen, which can easily cause damage to the TV screen or failure of the connection between the TV and the wall. Therefore, this type of protective cover directly installed on the screen has poor protection effect on the screen. In addition, since the protective cover itself lacks force-relieving ability, it is easy for the protective cover itself to shatter when hit, resulting in a shorter practical life of the protective cover.

[0034] It is worth mentioning that a mobile TV carrier may also be used in the rehabilitation of mental illness to transport the TV to different wards or psychotherapy rooms and other areas for the treatment of mental illness; in this case, the connecting unit 2 is configured to be fixed to the mobile TV carrier, so that the present invention can also be applied to such a mobile TV carrier to protect the screen installed on the mobile TV carrier.

[0035] Please continue reading Figure 5 、 Figure 6 , wherein the wall 5 connection unit 2 includes a wall 5 mounting plate 21 and a bending plate 22 arranged on the wall 5 mounting plate 21 .

[0036] During manufacturing, if the wall 5 connection unit 2 is made of metal material, the wall 5 mounting plate 21 and the bending plate 22 can be bent into shape by sheet metal processing; if the wall 5 connection unit 2 is made of plastic material, the wall 5 mounting plate 21 and the bending plate 22 can be formed by injection molding process; sheet metal processing and injection molding process are both mature manufacturing technologies, which makes the wall 5 connection unit 2 have the advantages of simple manufacturing and low manufacturing cost.

[0037] Please continue reading Figure 2 、 Figure 3 、 Figure 6 , wherein the wall 5 mounting plate 21 has at least one first slot 211 arranged along the length direction; the fastener passes through the first slot 211 and is connected to the wall 5.

[0038] Specifically, the first slot hole 211 is arranged along the length direction of the wall 5 mounting plate 21, and multiple sets of fasteners can be driven into the wall 5 through the first slot hole 211; wherein, the first slot hole 211 is preferably provided with two upper and lower ones, and the fasteners are preferably expansion screws so as to firmly fix the wall 5 mounting plate 21 from the upper and lower ends.

[0039] Please continue reading Figure 6 、 Figure 8 , wherein the bending plate 22 has a slide groove 221; the extension portion 32 passes through the slide groove 221 and can slide in the slide groove 221 along the first direction and the second direction.

[0040] By setting the sliding groove 221, the extension portion 32 can pass through the sliding groove 221 and be connected to the elastic portion 33; and the sliding groove 221 has a limiting and guiding function when the extension portion 32 slides along the first direction and the second direction, thereby limiting the extension portion 32 from sliding along directions other than the first direction and the second direction, so as to cooperate with the deformation and force unloading of the elastic portion 33.

[0041] Please continue reading Figure 5 、 Figure 6 , wherein the elastic portion 33 includes a spring 331 and two connecting pieces 332 fixedly connected to both ends of the spring 331 ; the connecting piece 332 has a threaded hole 3321 .

[0042] Specifically, the axial direction of the spring 331 is the first direction. Under this setting, the spring 331 can be compressed and deformed in the first direction, or it can be swung and deformed in the second direction; when one of the places on the protective plate 1 is hit, the spring 331 closest to that place will be compressed in the first direction first, and the springs 331 in the other three places will swing slightly in the second direction or in a direction perpendicular to the second direction to cooperate with the compression deformation of the spring 331 at that place, thereby absorbing most of the impact force to protect the screen 4 and the protective plate 1 itself; the two connecting pieces 332 at both ends of the spring 331 and the threaded hole 3321 in the connecting piece 332 are provided for connecting the spring 331 to the wall 5 mounting plate 21 and the extension part 32 respectively.

[0043] Please see further Figure 5 、 Figure 6 , wherein the wall 5 mounting plate 21 includes a first ring portion 212, an extension portion 32 and a second ring portion 321; two connecting pieces 332 are respectively arranged on the first ring portion 212 and the second ring portion 321, and are fixed by fasteners.

[0044] By setting the first collar portion 212 and the second collar portion 321, the two connecting pieces 332 set at both ends of the spring 331 have a mounting carrier, so that the fixing effect of the two connecting pieces 332 is better; during installation, the fastener passes through the first collar portion 212 or the second collar portion 321 and is fixed to the threaded hole 3321; it is worth noting that the fastener of the first collar portion 212 is preferably a countersunk screw to maintain the flatness of the wall 5 mounting plate 21 so that the wall 5 mounting plate 21 can fit the wall 5.

[0045] Please continue reading Figure 8 , wherein the wall 5 mounting plate 21 includes a slide groove 221 having a first limiting surface 2211 and a second limiting surface 2212 arranged along a first direction; when the spring 331 is unfolded, the extension portion 32 is limited by the first limiting surface 2211 so that the distance between the protection plate 1 and the wall 5 is maintained at L1; when the spring 331 is compressed, the extension portion 32 is limited by the second limiting surface 2212 so that the distance between the protection plate 1 and the wall 5 is not less than L2, and L2 is greater than the distance L3 between the playing surface of the screen 4 and the wall 5.

[0046] By setting the first limiting surface 2211 and the second limiting surface 2212 in the slide groove 221, the movement position of the extension part 32 in the first direction is limited. Specifically, when the extension part 32 is limited by the first limiting surface 2211, the spring 331 is still in a compressed state, that is, the extension part 32 is still pressed against the first limiting surface 2211 by the spring 331, so that the distance between the protection plate 1 and the wall 5 is maintained at L1; when the protection plate 1 is hit, the spring 331 is compressed in the first direction, and the extension part 32 moves in the first direction in the slide groove 221, and the maximum moving distance of the extension part 32 is limited by the second limiting surface 2212, so that the distance between the protection plate 1 and the wall 5 is not less than L2, and the distance between the playing surface of the screen 4 and the wall 5 is L3, and L2 is greater than L3, thereby protecting the screen 4 from impact.

[0047] Please continue reading Figure 5 、 Figure 8 , wherein the protection plate fixing portion 31 has a slot 311 , and one side of the protection plate 1 is configured to be embedded in the slot 311 and fixed by at least two sets of fasteners.

[0048] During installation, one side of the protective plate 1 is inserted into the slot 311 and fixed by a fastener provided on one side of the slot 311; further, the fasteners are provided in two groups and are provided on the side of the slot 311 away from the screen 4, and a soft pad can also be provided on the side of the slot 311 close to the screen 4, so that when the protective plate 1 or the protective plate connecting unit 3 is deformed or damaged by a significant impact force, there can still be a buffer between the protective plate fixing portion 31 and the screen 4.

[0049] Please continue reading Figure 1、 Figure 2 、 Figure 3 In this embodiment, the protection plate 1 is made of an elastic material in one piece and has freedom in a first direction; the protection plate 1 has an explosion-proof membrane.

[0050] In this embodiment, since the protective plate 1 is made as an integral part, it has the advantages of simple manufacturing and low manufacturing cost; and since the protective plate 1 is made of elastic material, when the middle part of the protective plate 1 is hit, it can produce an arc deformation along the first direction, and drive the four surrounding springs 331 to swing and deform in the second direction or in the direction of the second direction, thereby absorbing the impact force to protect the screen 4; when the impact force is removed, the protective plate 1 and the spring 331 are reset at the same time, so that the protective plate 1 can restore its original flatness; the explosion-proof membrane on the protective plate 1 can prevent fragments from flying and causing personal injury when the protective plate 1 is hit by a large impact force and bursts.

[0051] It is worth mentioning that in some other embodiments, the protective plate 1 can also be configured to be composed of two plate bodies. Specifically, the protective plate 1 includes an upper plate body and a lower plate body arranged up and down; the upper end of the upper plate body and the lower end of the lower plate body are embedded in the card slots 311 on both sides; the protective plate 1 further includes a reset portion, which is configured to connect the lower end of the upper plate body and the upper end of the lower plate body so that the upper plate body and the lower plate body are maintained in the same plane; when the protective plate 1 is impacted, the lower end of the upper plate body and the upper end of the lower plate body can move along the first direction, and when the impact is removed, the upper plate body and the lower plate body are reset; further, the reset portion can adopt a hinge with a torsion spring.

[0052] Please continue reading Figure 2 、 Figure 7 , wherein the wall 5 mounting plate 21 has a first hollow area 213; the bending plate 22 has a second hollow area 222.

[0053] By setting the first hollow area 213 and the second hollow area 222, the weight of the wall 5 mounting plate 21 can be reduced and materials can be saved; at the same time, the second hollow area 222 is also conducive to the lead wire passing through to connect with the screen 4, and it is also convenient for the user to control the buttons on the side of the screen 4.

[0054] The above description is merely a description of the preferred embodiment of the present invention and should not be construed as limiting the claims.
