Description

Technical Field

[0001] The present invention relates to the technical field of display screen transportation, and in particular to a display screen anti-collision protection device and a display screen. Background Art

[0002] With the development of display technology, display screens are more and more widely used in various public places. However, display screens are fragile. During transportation, handling, and installation, the LED lamp beads on the edge of the LED display unit are easily knocked off after being hit by external forces, which brings a lot of maintenance work. With the development of small-pitch LED display screens, the size of LED lamp beads is getting smaller and smaller, and the welding surface is getting smaller and smaller during the SMT process. The LED lamp beads are more likely to be knocked off, and the difficulty of maintenance is increasing. Therefore, it is necessary to develop anti-collision technology for LED display screens to effectively prevent damage to the display screen.

[0003] Although the anti-collision protection device used in the prior art can effectively prevent damage to the display screen, its structure is formed by bending, the structure is complex, and the processing cycle is long; and the movable connection between the display screen anti-collision protection device and the display screen body is located on the inner side of the corner of the display screen body, which is inconvenient to install; due to the structure of the anti-collision protection device, the display screen body needs to be greatly modified.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Summary of the invention

[0005] The main purpose of the present invention is to provide a display screen anti-collision protection device and a display screen, which have simple structural design, convenient installation and easy operation, and do not require major changes to the box.

[0006] The present invention provides a display screen anti-collision protection device, which is used to be arranged on a display screen body to provide anti-collision protection for the display screen body, and comprises a protection member, wherein the protection member is longitudinally located at the side wall of the display screen body and can rotate relative to the display screen body around a rotation axis so that the protection member can switch between an open state and a closed state. In the open state, the end of the protection member exceeds the front surface of the display screen body to achieve anti-collision protection, and in the closed state, the protection member is retracted so that the end is lower than the front surface of the display screen body.

[0007] Furthermore, it also includes a base, which is located at the rear end of the display screen body and is used to be connected to the display screen body. The front end of the base is provided with a receiving groove. In the open state, the end of the protective member exceeds the front surface of the display screen body. In the closed state, the protective member is accommodated in the receiving groove.

[0008] Furthermore, a connecting torsion spring is provided at the rear end of the base, and the base and the protective member are rotatably connected via the connecting torsion spring. In the open state, the elastic force of the connecting torsion spring pushes the protective member to rotate out of the accommodating groove around the connecting torsion spring, and further rotates so that the end of the protective member exceeds the front surface of the display screen body.

[0009] Furthermore, a control member is provided at the front end of the base. When in the closed state, the protective member is retracted into the accommodating groove, and the control member blocks the outside of the protective member, thereby fixing the protective member in the accommodating groove; when in the open state, the control member releases the protective member, and the protective member rotates.

[0010] Furthermore, the control member includes a control torsion spring and a control switch, the control torsion spring connects the base and the control switch, and a buckle is provided on the control switch. In the closed state, the control torsion spring pulls the control switch downward due to the elastic force, so that the control member is blocked on the outside of the protective member through the buckle; in the open state, the control switch is lifted to separate the buckle from the protective member, releasing the protective member, and the protective member rotates.

[0011] Furthermore, a baffle is provided at the end of the protective member. In the closed state, the protective member is accommodated in the receiving groove, and the baffle and the buckle restrain each other to fix the protective member in the receiving groove.

[0012] Furthermore, the protection member is further provided with a buffer body, and in the open state, the buffer body isolates the protection member from the outer side wall of the display screen body.

[0013] The present invention also provides a display screen, comprising a plurality of display screen anti-collision protection devices as described above and a display screen main body.

[0014] Furthermore, a mounting groove is provided at a corner of the display screen body, the display screen anti-collision protection device is located in the mounting groove, and the base is fixedly connected to the mounting groove.

[0015] Furthermore, the display screen body is rectangular, and the display screen anti-collision protection devices are arranged at four corners of the display screen body.

[0016] The display screen anti-collision protection device of the present invention has a protection member and a base arranged longitudinally, and occupies a small space in a closed state. In an open state, the protection member rotates from the outer rear side to the front surface of the display screen body, which has a small impact on the display screen body and does not require major changes to the display screen body.

[0024] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] Please refer to Figure 1 The embodiment of the present invention relates to a display screen anti-collision protection device and a display screen. The display screen may be an LED display screen, an LCD display screen, etc., which all require anti-collision protection. In particular, the LED display screen has lamp beads at the corners that are easily damaged by collision during transportation or use. The display screen includes a display screen body 11 and a display screen anti-collision protection device 12. The display screen anti-collision protection device 12 is located at the side wall of the display screen body 11.

[0026] The display screen anti-collision protection device 12 includes a base 121 and a protection member 122. The base 121 is fixedly connected to the display screen body 11, and the protection member 122 is rotatably connected to the base 121, so that the protection member 122 can rotate relative to the display screen body 11, so that the display screen anti-collision protection device 12 can switch between an open state and a closed state. In the open state, the end of the protection member 122 exceeds the front surface 112 of the display screen body 11 to achieve anti-collision protection; in the closed state, the protection member 122 is retracted so that the end is lower than the front surface 112 of the display screen body 11.

[0027] Please refer to Figure 2The base 121 includes a base body 1211, a connecting torsion spring 1212, a control member 1213 and a buffer spring 1214. A receiving groove 12111 is provided in the middle of the base body 1211, a first connecting portion 12112 is provided at the rear end, and a second connecting portion 12113 is provided at the front end. The end of the first connecting portion 12112 is pivotally connected to the connecting torsion spring 1212, and the second connecting portion 12113 is pivotally connected to the control member 1213. In the open state, the end of the protective member 122 exceeds the front surface 112 of the display screen body 11, and in the closed state, the protective member 122 is accommodated in the receiving groove 12111. Due to the function of the receiving groove 12111, in the closed state, the volume of the display screen anti-collision protection device 12 can be significantly reduced, thereby reducing the packaging and transportation costs of the display screen.

[0028] In this embodiment, the base 121 and the protective member 122 are rotatably connected through the end of the first connecting portion 12112, and the connecting torsion spring 1212 abuts against the protective member 122. In the open state, the elastic force of the connecting torsion spring 1212 pushes the protective member 122 to rotate around the end of the first connecting portion 12112 out of the receiving groove 12111, and further rotates so that the end of the protective member 122 exceeds the front surface 112 of the display screen body 11. The connecting torsion spring 1212 always gives the protective member 122 a driving force, so that in the open state, there is no need to manually operate the protective member 122 to rotate, and there is no need to set up a separate structure to fix the position of the protective member 122. Secondly, because the protective member 122 and the base 121 are longitudinally connected, in the open state, the protective member 122 goes around from the outer rear side to the front surface 112 of the display screen body 11, and will not interfere with the display screen body 11, and there is no need to make major changes to the display screen body 11.

[0029] In other embodiments, the base 121 and the protection member 122 may also be connected in other ways, and the protection member 122 may also be directly connected to the display screen body 11 .

[0030] In this embodiment, the buffer spring 1214 is a rubber pad, located between the connecting torsion spring 1212 and the first connecting portion 12112, and plays a buffering role to prevent the connecting torsion spring 1212 and the first connecting portion 12112 from scratching each other, thereby protecting the seat body 1211 and the connecting spring 1212 and extending their service life. In other embodiments, the buffer spring can also be replaced by a spring washer, felt, sponge pad, etc.

[0031] Please refer to Figure 4 and Figure 5The control member 1213 includes a control torsion spring 12131 and a control switch 12132. The control member 1213 is pivotally connected to the second connection portion 12113. The control torsion spring 12131 abuts against the seat 1211 and the control switch 12132, and a buckle 12133 is provided on the control switch 12132. In the closed state, the control torsion spring 12131 pulls the control switch 12132 downward due to the elastic force, so that the control member 1213 is blocked outside the protective member 122 through the buckle 12133, and the protective member 122 is fixed in the receiving groove 12111. In the open state, the control switch 12132 is lifted to separate the buckle 12133 from the protective member 122, and the protective member 122 is released. The end of the protective member 122 exceeds the front surface 112 of the display screen body 11 under the action of the connecting torsion spring 1212.

[0032] In this embodiment, the protection member 122 includes a body 1221 and a pivoting portion 1222 formed by vertically extending from one end of the body, a baffle 12211 is provided at the end of the body 1221, a buffer body 12212 is provided on the inner side of the middle part, and a pivoting hole 12221 is provided at the end of the pivoting portion 1222 for pivoting with the first connecting portion 12112. In the closed state, the protection member 122 is accommodated in the receiving groove 12111, and the baffle 12211 and the buckle 12133 constrain each other to fix the protection member 122 in the receiving groove 12111.

[0033] The function of the control member 1213 and the baffle 12211 is to fix the protection member 122 on the base without setting up another structure, thereby simplifying the structure of the display screen anti-collision protection device. When switching from the closed state to the open state, only the control switch 12132 needs to be lifted to release the protection member 122, and the switching can be completed, which is simple to operate. Of course, this is only one embodiment. In other embodiments, other methods can be used to control the switching between the closed state and the open state, and other methods can also be used to fix the protection member 122 in the receiving groove 12111.

[0034] The buffer body 12212 is a rubber column. When in the open state, the buffer body 12212 is located between the protective member 122 and the display screen body 11 to absorb the impact force when the protective member 122 rotates and protect the display screen body 11. In other embodiments, the buffer body 12212 can also use other buffer protection methods, such as sponge strips, rubber pads, springs, etc.

[0035] Please refer to Figure 3 , Figure 6 and Figure 7The display screen body 11 is rectangular, and a mounting groove 111 is provided at the rear of each of the four corners. The display screen anti-collision protection device 12 is located in the mounting groove 111. The bottom of the mounting groove 111 has a first threaded hole 1111 and a second threaded hole 1112, and the bottom of the first connecting portion 12112 has a first through hole 12114 and a second through hole 12115. In addition, the display screen anti-collision protection device 12 is also provided with a first bolt 123 and a second bolt 124. The first bolt 123 and the second bolt 124 pass through the first through hole 12114 and the second through hole 12115 respectively and match the first threaded hole 1111 and the second threaded hole 1112 to fix the base 121 in the mounting groove 111.

[0036] The mounting groove 111 accommodates the display screen anti-collision protection device 12, so that when the display screen anti-collision protection device 12 is in the closed state, the entire display screen body 11 has a more regular shape and a smaller volume, thereby reducing packaging and transportation costs. In other embodiments, the display screen body 11 may also be in other shapes, and the display screen anti-collision protection device 12 may not be located at a corner position. In addition to bolt connection, other connection methods such as gluing, snap connection, etc. may also be used for the display screen body 11 and the display screen anti-collision protection device 12.

[0037] The present invention has many advantages as follows.

[0038] 1. The base and the protective member are arranged vertically, and the base is located on the outer rear side of the corner of the display screen body. In the process of switching from the closed state to the open state, the protective member rotates from the outer rear side to the front surface of the display screen body, which has little impact on the display screen body and does not require major changes.

[0039] 2. The protective member can be accommodated in the base when in a closed state, and the base can be accommodated in the receiving groove of the display screen body, thereby reducing the volume of the entire structure, occupying a small space, and reducing packaging and transportation costs.

[0040] 3. When switching from the closed state to the open state, just lift the control switch to release the protective part. The end of the protective part will exceed the front surface of the display screen under the action of the connecting torsion spring, and the switching is completed. There is no need to manually control the movement of the protective part. The operation is simple and labor-saving.
