In this document, directional terms such as "upper" and "lower" are used interchangeably with... Figure 3 With the orientation as a reference, the direction where the iron sheet body 3 is located is the "front" and the direction where the threaded section 11 is located is the "back".

[0032] This utility model provides a front-mounted magnet assembly for an LED display screen and an LED display screen, including a magnet base and a magnet body. The magnet base is an integrally formed part, including a threaded section and a guide mounting groove. The threaded section is located on the back of the guide mounting groove and is used to connect the magnet base to the LED display cabinet. The guide mounting groove includes a metal sheet mating area and a magnet mounting area from front to back. The magnet mounting area is where the magnet body is mounted. The metal sheet mating area is used to mate with the metal sheet body of the LED display module. The metal sheet mating area is provided with a guide slope and a mating plane. The guide slope is in contact with the side wall of the magnet mounting area, and the angle α between the guide slope and the front of the magnet body is an obtuse angle. The inner side of the mating plane... It connects to the guide ramp and its outer side connects to the outer wall of the magnet base.

It can achieve precise positioning of the magnetic attraction operation between the LED display module and the display cabinet without the need for manual fine-tuning of the LED display module position, achieving rapid positioning and installation of the LED display module and improving the installation efficiency of the LED display module. It solves the technical problem that the existing magnetic attraction installation between the LED display module and the display cabinet cannot achieve precise guidance and positioning and requires manual fine-tuning.

[0033] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0034] Example 1:

[0035] Reference Figure 1 and Figure 2 This embodiment 1 provides a magnet assembly for front mounting of an LED display screen, including a magnet base 1 and a magnet body 2.

[0036] See Figure 2 The magnet base 1 is an integrally molded part, including a threaded section 11 and a guide mounting groove. The threaded section 11 is located on the back of the guide mounting groove and is used to connect the magnet base 1 to the LED display cabinet. The guide mounting groove includes an iron sheet mating area and a magnet mounting area 121 from front to back. The magnet mounting area 121 is equipped with a magnet body 2.

[0037] like Figure 2 and Figure 3As shown, the iron sheet mating area is used to mate with the iron sheet body 3 of the LED display module. The iron sheet mating area is provided with a guide slope 1221 and a mating plane 1222. The guide slope 1221 is in contact with the side wall of the magnet mounting area 121, and the angle α between the guide slope 1221 and the front of the magnet body 2 is an obtuse angle. The inner side of the mating plane 1222 is in contact with the guide slope 1221, and the outer side is in contact with the outer wall of the magnet base 1. The mating plane 1222 is provided to protect the magnet body 2 by fitting against the step of the iron sheet body 3, and to improve the structural strength of the magnet base 1, making the magnet base 1 less prone to damage during installation and use, and extending its service life.

[0038] In some feasible solutions, the included angle α is ≥120° and ≤150°. The gradually narrowing structure allows the LED display module to automatically align as it approaches the LED display cabinet, achieving positioning. If the included angle α is too large, the guide stroke of the guide slope 1221 will be too long; if the included angle α is too small, the fault tolerance of the guide will decrease. Therefore, the included angle α in this application is controlled between 120° and 150°.

[0039] In some feasible solutions, the included angle α is 135°, which means that the tilt angle of the guide slope 1221 is 45°, so that the guiding efficiency and the structural strength of the magnet base 1 are both at a good level.

[0040] See Figure 3 In practical applications, several protrusions 13 are provided on the top of the side wall of the magnet mounting area 121 along its circumferential direction. The protrusions 13 are used to abut against the side wall of the magnet body 2 to help fix the magnet body 2 in the magnet mounting area 121, ensuring that the magnet body 2 is firmly installed and maintaining magnetic stability in the event of sudden external impact or vibration.

[0041] Because the magnet base 1 is provided with a magnet mounting area 121 and an iron sheet mating area, and the iron sheet mating area is provided with a guide slope 1221 and a mating plane 1222, compared with the existing LED display module and cabinet fixed by magnetic iron sheet and magnet adsorption, and positioned by positioning post, the mating boss 31 of the iron sheet body 3 of this application automatically slides along the guide slope 1221 under the magnetic attraction of the magnet body 2 until the iron sheet body 3 is accurately positioned on the magnet body 2. The installation experience is better, the alignment accuracy of the LED display module and the display cabinet is higher, and it is more suitable for small-pitch LED displays. It can realize the precise positioning of the magnetic attraction operation between the LED display module and the display cabinet without the need for manual fine-tuning of the position of the LED display module. It achieves fast and accurate positioning and installation of the LED display module, improves the installation efficiency of the LED display module, and solves the technical problem that the positioning of the magnetic attraction installation operation between the LED display module and the display cabinet is not accurate enough and requires manual fine-tuning.

[0042] See Figure 1 The magnet mounting area 121 is generally cylindrical, the magnet body 2 is cylindrical, and the iron sheet mating area is generally truncated cone-shaped. The magnet base 1 is made of high-strength metal material, which is also magnetically conductive and has undergone rust-proof treatment, which can effectively prevent rust and corrosion, extend the service life of the magnet base 1, and reduce maintenance costs.

[0043] Example 2:

[0044] Reference Figures 4 to 5 This embodiment 2 provides an LED display screen, including an LED display cabinet and an LED display module. The LED display cabinet is equipped with a magnet assembly for front mounting of the aforementioned LED display screen. An iron sheet body 3 is mounted on the back of the LED display module. The iron sheet body 3 and the magnet body 2 are magnetically attracted to each other, and the rear end of the iron sheet body 3 is engaged with the iron sheet mating area. The LED display module and the LED display cabinet are magnetically attracted to each other, realizing the front mounting of the LED display screen.

[0045] See Figures 3 to 5 As a feasible solution, the rear end of the iron sheet body 3 is provided with a mating boss 31 and a step 32. The side wall of the mating boss 31 is provided with an inclined surface adapted to the guide slope 1221. The step 32 is located at the back edge of the iron sheet body 3 and connects with the inclined surface. The step 32 is in contact with the mating plane 1222 of the magnet base 1. The mating plane 1222 of the magnet base 1 and the step 32 of the iron sheet body 3 are in contact, and the guide slope 1221 and the inclined surface of the mating boss 31 are in contact, preventing dust and other particles from entering the interior of the magnet base 1, thus better protecting the magnet body 2.

[0046] A metal sheet mating area is set in the guide mounting groove, and a mating boss 31 is set on the back of the metal sheet body 3. The metal sheet body 3 is closer to and more concentrated on the magnetic attraction surface of the magnet body 2. The effective contact area between the metal sheet body 3 and the magnet body 2 is larger, and the magnetic attraction effect is better.

[0047] In addition, a chamfer is provided at the junction of the mating plane 1222 and the guide slope 1221. Correspondingly, a chamfer is provided at the junction of the inclined surface of the mating boss 31 and the back of the iron sheet body 3. This ensures that the operation of the iron sheet body 3 sliding into the guide slope 1221 is smoother and more fluid, avoids scratching the guide slope 1221, and extends the service life of the magnet base 1.
