[0057] The utility model provides a screen anti-collision device, which is suitable for application scenarios where anti-collision protection is provided for the top corners of a display screen body. The device can protect the top corners of the display screen unit and effectively reduce the risk of corner chipping.

[0058] See also Figures 1 to 4 The spliced display screen module provided in this embodiment includes at least two display screen units 100; further, the display screen unit 100 includes a display screen body 100a, wherein each vertex position of the display screen body 100a is provided with a screen anti-collision device 100b for providing anti-collision protection for the vertex position.

[0059] It should be noted that the focus of this embodiment is to set the screen anti-collision device 100b to provide anti-corner protection when splicing two adjacent display screen units 100. The post-splicing fixing structure between the two adjacent display screen units 100 is not the focus of this embodiment and will not be described in detail.

[0060] See also Figures 5 to 8The screen collision prevention device 100b includes a housing assembly 1, a protective assembly 2, and a drive assembly 3. The housing assembly 1 includes a receiving cavity and a special-shaped guide groove 101 connecting the receiving cavity to the external space of the housing assembly 1. One end of the protective assembly 2 is located outside the receiving cavity, and the other end extends into the receiving cavity and is slidably connected to the housing assembly 1 along the special-shaped guide groove 101. The drive assembly 3 is connected to the protective assembly 2.

[0061] In which, the protective component 2 has an extended state in which it is driven in the forward direction by the driving component 3 and moves outward in two dimensions, a first direction and a second direction, relative to the shell component 1; and has a retracted state in which it is driven in the reverse direction by the driving component 3 and moves in two dimensions, a first direction and a second direction, relative to the shell component 1; wherein, the first direction and the second direction are perpendicular to each other.

[0062] It is worth noting that as the installation angle of the screen anti-collision device 100b changes, the first direction and the second direction will also change accordingly. For the convenience of understanding and explanation, in this embodiment, the screen anti-collision device 100b is installed on the back of the display screen body 100a. The first direction is the front and back direction of the display screen body 100a, and the second direction is the up and down direction of the display screen body 100a.

[0063] The screen anti-collision device 100b, the display screen unit 100, and the spliced display screen module provided in this embodiment are provided with a screen anti-collision device 100b at each vertex position of the display screen unit 100:

[0064] When protection is required for the top corner of the display screen unit 100, the driving assembly 3 drives the protection assembly 2 to translate outwardly along the special-shaped guide groove 101 relative to the housing assembly 1 to an extended state, so that the end of the protection assembly 2 located outside the accommodating cavity can translate outwardly to the outside of the top corner of the display screen unit 100, thereby providing protection for the top corner.

[0065] When it is necessary to splice the display screen units 100 to form a spliced display screen module, the driving component 3 drives the protective component 2 to move inward along the special-shaped guide groove 101 relative to the outer shell component 1 to a retracted state, so that the end of the protective component 2 located outside the accommodating cavity protrudes outward to block the splicing between two adjacent display screen units 100.

[0066] Therefore, the screen anti-collision device 100b, the display screen unit 100 and the spliced display screen module provided by the present invention can protect the top corner position of the display screen unit 100 and effectively reduce the risk of corner chipping.

[0067] In this embodiment, the special-shaped guide groove 101 includes a straight section 1011 extending along a first direction, and an inclined section 1012 inclined relative to the straight section 1011.

[0068] When the protection component 2 is in the extended state, the protection component 2 slides to the end of the straight section 1011 away from the inclined section 1012;

[0069] When the protection component 2 is in the retracted state, the protection component 2 slides to an end of the inclined section 1012 away from the straight section 1011 .

[0070] Optionally, the protective assembly 2 includes an L-shaped protective member 201, a connecting rod assembly 202, and a 7-shaped sliding member 203. The L-shaped protective member 201 includes a transverse portion 2011 located outside the accommodating cavity and a longitudinal portion 2012 extending into the accommodating cavity; one end of the connecting rod assembly 202 is hinged to the longitudinal portion 2012; the 7-shaped sliding member 203 is slidably connected to the housing assembly 1 along the first direction; wherein the 7-shaped sliding member 203 abuts against the driving assembly 3 and, after being driven by the driving assembly 3, drives the L-shaped protective member 201 to slide along the special-shaped guide groove 101 via the connecting rod assembly 202.

[0071] The drive assembly 3 includes a transverse spring 301 and a longitudinal abutment block 302. The transverse spring 301 abuts against the side of the 7-shaped sliding member 203 away from the L-shaped protective member 201, and is used to push the protective assembly 2 toward the straight section 1011. One end of the longitudinal abutment block 302 is located outside the accommodating cavity, and the other end extends into the accommodating cavity and is slidably connected to the housing assembly 1 along the second direction.

[0072] In which, the 7-shaped sliding member 203 is provided with a guiding inclined surface 2031 abutting against the longitudinal abutment block 302. When the longitudinal abutment block 302 is driven to slide into the shell assembly 1, the 7-shaped sliding member 203 drives the L-shaped protective member 201 to slide toward the inclined section 1012 under the guidance of the guiding inclined surface 2031.

[0073] Specifically, the longitudinal abutment block 302 is provided with a longitudinal guide groove 3021 extending along the second direction, and the interior of the accommodating cavity is provided with a plurality of fixed guide posts 102 extending into the longitudinal guide groove 3021, so that the longitudinal abutment block 302 can only slide up and down relative to the housing assembly 1, and cannot slide forward, backward, left, or right.

[0074] When the protective assembly 2 is in the extended state, the longitudinal abutment block 302 protrudes more than the transverse portion 2011. Specifically, a protruding dimension a of the longitudinal abutment block 302 relative to the housing assembly 1 is greater than a protruding dimension b of the transverse portion 2011 relative to the housing assembly 1.

[0075] When the protective assembly 2 is in the retracted state, the longitudinal abutment block 302 is flush with the transverse portion 2011 . Specifically, the protruding dimension a of the longitudinal abutment block 302 relative to the outer shell assembly 1 is equal to the protruding dimension b of the transverse portion 2011 relative to the outer shell assembly 1 .

[0076] The screen anti-collision device 100b provided in this embodiment has a detailed working process as follows:

[0077] (1) See Figure 1 and Figure 2 Before splicing

[0078] The transverse spring 301 pushes the 7-shaped slide 203 forward so that:

[0079] ① The L-shaped protective member 201 slides to the front end of the straight section 1011 and enters the extended state, with the horizontal portion 2011 located directly above the top corner of the display screen body 100a;

[0080] When the upper and lower parts are joined together, the top surface of the horizontal portion 211 can provide vertical protection to prevent other objects from directly colliding with the display screen body 100a from above.

[0081] ② The 7-shaped sliding member 203 slides to the left, so that the longitudinal abutment block 302 abuts against the upper portion of the guide slope 2031 , and the longitudinal abutment block 302 slides upward to a higher position relative to the housing assembly 1 ;

[0082] (2) See Figure 3 and Figure 4 , when splicing along the second direction (up and down direction)

[0083] ① When the two display screen units 100 approach each other, since the longitudinal abutment blocks 302 are larger than the outer projection of the housing assembly 1, the longitudinal abutment blocks 302 of the two display screen units 100 will first abut each other;

[0084] ② After the two longitudinal abutment blocks 302 abut against each other, as the two display screen units 100 continue to approach each other, the longitudinal abutment blocks 302 gradually slide inward relative to the housing assembly 1, overcoming the elastic force of the transverse spring 301 and driving the 7-shaped sliding member 203 to move backward;

[0085] ③ The backward movement of the 7-shaped sliding member 203 drives the L-shaped protective member 201 to slide to the inclined section 1012. Since the inclined section 1012 is arranged to be inclined downward, after sliding backward along the straight section 1011 for a distance, the L-shaped protective member 201 will slide downward along the inclined section 1012 to a retracted state. At this time, the L-shaped protective member 201 has not only moved backward to be separated from the upper part of the display screen body 100a, but has also moved downward to avoid affecting the upper and lower splicing of the two display screen units 100.

[0086] It should be noted that during the backward sliding of the L-shaped protective member 201, as soon as the pressure applied to the longitudinal abutment block 302 is removed, the transverse spring 301 can automatically push the L-shaped protective member 201 back to the extended state to provide protection, thereby greatly improving the timeliness of the chipping protection.

[0087] (3) When splicing along the third direction (left and right direction)

[0088] See also Figure 5 , strictly control the installation position of the screen anti-collision device 100b on the display screen body 100a, so that the side position of the horizontal part 2011 and the side position of the display screen body 100a are on the same vertical plane, or, make the side position of the horizontal part 2011 slightly protrude a little bit from the side position of the display screen body 100a. Then, when the left and right sides are spliced together, the side surfaces of the horizontal parts 2011 of the two adjacent display screen units 100 will first contact each other, thereby providing left and right protection and avoiding direct collision with the top corner position of the display screen body 100a when splicing the left and right sides.

[0089] Optionally, the connecting rod assembly 202 includes two parallel connecting rod bodies 2021, one end of the connecting rod body 2021 is hinged to the L-shaped protective member 201 through a first rotating shaft 2022; the other end is hinged to the 7-shaped sliding member 203 through a second rotating shaft 2023; the first rotating shaft 2022 on one of the connecting rod bodies 2021 extends into the special-shaped guide groove 101 and moves along the special-shaped guide groove 101.

[0090] It should be noted that the first rotating shaft 2022 extending into the special-shaped guide groove 101 can limit the sliding trajectory of the entire protective component 2, so that the sliding trajectory of the protective component 2 is completely consistent with the shape of the special-shaped guide groove 101; the two connecting rod bodies 2021 are set to ensure that the protective component 2 always maintains a translational motion state during the back-and-forth switching between the extended state and the retracted state, and does not rotate, thereby avoiding the horizontal part 2011 from colliding with the display screen unit 100 due to rotation.

[0091] In this embodiment, an adjustment bolt 303 is threadedly connected to the housing assembly 1, and the transverse spring 301 is located between the adjustment bolt 303 and the 7-shaped sliding member 203. By turning the adjustment bolt 303, the elastic force of the transverse spring 301 can be adjusted, thereby adjusting the pressure required to be applied to the longitudinal abutment block 302 when the protective assembly 2 retracts.

[0092] It should be noted that in some other embodiments, the drive assembly 3 may also be a linear drive mechanism, such as an electric cylinder or a pneumatic cylinder, for driving the 7-shaped slide 203 to slide forward and backward. When chipping protection is required, the linear drive mechanism extends, driving the protection assembly 2 to slide forward to an extended state; when splicing is required, the linear drive mechanism retracts, driving the protection assembly 2 to slide backward to a retracted state.

[0093] In summary, the screen anti-collision device 100b, the display unit 100, and the spliced display module provided in this embodiment have the following advantages:

[0094] ① The protective component 2 can be extended outward relative to the housing component 1 to protect the top corner of the display screen body 100a, and can also be retracted inward relative to the housing component 1 to prevent the splicing operation between two adjacent display screen units;

[0095] ② The transverse spring 301 and the longitudinal abutment block 302 work together. As soon as the pressure applied to the longitudinal abutment block 302 is removed, the transverse spring 301 can automatically push the L-shaped protection member 201 back to the extended state to provide protection, greatly improving the timeliness of the chipping protection.

[0096] ③ Two connecting rod bodies 2021 are provided to ensure that the protective component 2 always maintains a translational motion state during the back-and-forth sliding process and does not rotate, thereby preventing the horizontal portion 2011 from hitting the display unit 100 due to rotation;

[0097] ④ By turning the adjusting bolt 303 , the elastic force of the transverse spring 301 can be adjusted, thereby adjusting the pressure required to be applied to the longitudinal abutment block 302 when the protective assembly 2 retracts.

[0098] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
