[0023] Figure 1A It is a top view schematic diagram of a display device according to an embodiment of the present invention. Figure 1B It is demolished Figure 1A A top view of the border. Figure 1C yes Figure 1B A top view of the knob being removed from the side wall of the panel bracket. Figure 1A and Figure 1B In this embodiment, the display device 100 includes a housing 110, a panel group 120, a plurality of knobs 130 and a frame 140, wherein the panel group 120 is fixed to the housing 110 by the plurality of knobs 130, and the frame 140 is installed on the housing 110 to cover the edges of the panel group 120 and the plurality of knobs 130.

[0024] like Figure 1B and Figure 1C As shown, the panel assembly 120 is mounted on the housing 110. The panel assembly 120 includes a panel bracket 121 and a panel 122 fixed to the panel bracket 121. The panel bracket 121 includes a sidewall 1211 surrounding the panel 122. Meanwhile, a plurality of knobs 130 are pivotally mounted on the housing 110 and distributed around the panel bracket 121. For example, the knobs 130 may be located on the upper and lower sides, left and right sides, or all around the panel bracket 121.

[0025] Figure 2A yes Figure 1B Schematic diagram of a partial cross-section along line segment 2A-2A. Figure 2B yes Figure 1C Schematic diagram of the local section along line segment 2B-2B. Figure 1B and Figure 2A As shown, the panel 122 is fixed inside the side wall 1211, and each knob 130 is located outside the side wall 1211. Figure 1B and Figure 2AIn the locked state shown, the locking flange 1301 of each knob 130 is positioned directly above the side wall 1211 and presses against the top and side surfaces of the side wall 1211 to prevent the panel assembly 120 from accidentally detaching from the housing 110 or from slipping on the housing 110. Furthermore, the multiple knobs 130 distributed on the upper and lower sides, left and right sides, or all around the panel bracket 121 can exert a clamping force on the panel assembly 120, thereby firmly securing the panel assembly 120 to the housing 110.

[0026] like Figure 1C and Figure 2B As shown, the operator can rotate each knob 130 to move the locking flange 1301 of each knob 130 away from the side wall 1211, thereby switching to the unlocked state. In this way, the operator can quickly remove the panel assembly 120 from the housing 110 for maintenance. After the maintenance is completed, the operator can reinstall the panel assembly 120 on the housing 110, and then rotate each knob 130 so that the locking flange 1301 of each knob 130 moves closer to the side wall 1211 and presses against the top and side surfaces of the side wall 1211, thereby firmly fixing the panel assembly 120 to the housing 110, as shown in FIG. Figure 1B and Figure 2A shown.

[0027] In other examples, the damaged panel set 120 can be replaced with another undamaged panel set, and the panel set can be mounted and fixed on the housing 110 via the knob 130 .

[0028] Continuing with the above, panel assembly 120 can be installed, fixed, or removed simply by rotating knob 130. This not only significantly improves the efficiency of panel assembly 120 installation and removal, but also reduces the risk of damage during the installation and removal process. Furthermore, the use of knob 130 in place of screws reduces the number of screws used, further promoting environmental protection and sustainable development.

[0029] Figure 3A yes Figure 1B Schematic diagram of a partial cross-section along line segment 3A-3A. Figure 3B yes Figure 1C Schematic diagram of the partial section along line 3B-3B. Please refer to Figure 1B 、 Figure 1C 、 Figure 3A and Figure 3B In this embodiment, each knob 130 is adapted to rotate about the axis 101 relative to the housing 110 and to slide along a direction 102 parallel to the axis 101 while rotating, such as moving up and down or sliding vertically.

[0030] like Figure 1B 、 Figure 2A and Figure 3AAs shown, each knob 130 rotates along the first rotation direction R1 so that the locking flange 1301 moves closer to and presses against the side wall 1211 of the panel bracket 121. Figure 1C 、 Figure 2B and Figure 3B As shown, each knob 130 is rotated in a second rotation direction R2 opposite to the first rotation direction R1 , so that the locking flange 1301 moves away from the side wall 1211 of the panel bracket 121 .

[0031] exist Figure 1B 、 Figure 2A and Figure 3A In the locked state shown, the top of each knob 130 is at a first height H1 from the bottom of the housing 110. Figure 1C 、 Figure 2B and Figure 3B In the unlocked state shown, the top of each knob 130 is spaced from the bottom of the housing 110 by a second height H2, which is greater than the first height H1. Specifically, as each knob 130 rotates in the first rotational direction R1, the locking flange 1301 gradually moves closer to the side wall 1211 of the panel bracket 121. Simultaneously, the height of each knob 130 gradually decreases, for example, from the second height H2 to the first height H1, allowing the locking flange 1301 to press against the side wall 1211. Conversely, as each knob 130 rotates in the second rotational direction R2, the locking flange 1301 gradually moves away from the side wall 1211 of the panel bracket 121. Simultaneously, the height of each knob 130 gradually increases, for example, from the first height H1 to the second height H2, allowing the locking flange 1301 to lift off the side wall 1211.

[0032] like Figure 2A 、 Figure 2B 、 Figure 3A and Figure 3B As shown, in this embodiment, the housing 110 is provided with a plurality of positioning members 150 around the sidewall 1211. Specifically, the positioning members 150 are located outside the sidewall 1211 and are distributed on the upper and lower sides, left and right sides, or all around the panel bracket 121. Furthermore, the plurality of knobs 130 are respectively mounted on the positioning members 150, each knob 130 having a spiral groove 131, and each positioning member 150 having a protruding pin 151.

[0033] The pin 151 of each positioning member 150 is positioned within the corresponding spiral groove 131 of the knob 130, and the height and position of the pin 151 remain fixed. Through the cooperation between the pin 151 and the spiral groove 131, when each knob 130 rotates relative to the corresponding positioning member 150 about the axis 101, each knob 130 can also slide relative to the corresponding positioning member 150 in a direction 102 parallel to the axis 101, for example, moving up and down or sliding vertically.

[0034] like Figure 2A and Figure 2B As shown, in this embodiment, each knob 130 has a knob groove 132 communicating with the spiral groove 131 and a first knob column 133 located within the knob groove 132, and each positioning member 150 also has a first positioning groove 152 and a positioning column 153 located within the first positioning groove 152. Specifically, each positioning member 150 is inserted into the knob groove 132 of the corresponding knob 130, wherein the knob groove 132 communicates with the first positioning groove 152, and the first knob column 133 is aligned with the positioning column 153.

[0035] On the other hand, a spring 160 is disposed between each knob 130 and the corresponding positioning member 150, and the spring 160 is located within the communicating knob groove 132 and the first positioning groove 152. Specifically, the spring 160 may be a tension spring and has a first portion 161 that is sleeved on the first knob column 133 and a second portion 162 that is sleeved on the positioning column 153.

[0036] like Figure 1C 、 Figure 2B and Figure 3B As shown, during the process of each knob 130 rotating along the second rotation direction R2, the height of each knob 130 gradually increases, stretching the corresponding spring 160 to cause elastic deformation. Furthermore, the elastic restoring force exerted by each spring 160 on the corresponding knob 130 can be a downward pulling force, thereby preventing the knob 130 from accidentally detaching from the positioning member 150. Figure 1B 、 Figure 2A and Figure 3A As shown, during the rotation of each knob 130 along the first rotation direction R1, the elastic restoring force of each spring 160 acting on the corresponding knob 130 not only helps to accelerate the rotation and descent of the knob 130, but also enables the locking flange 1301 that contacts the side wall 1211 of the panel bracket 121 to apply downward pressure on the side wall 1211.

[0037] like Figure 2A and Figure 2B As shown, the outer diameter OD1 of the first knob column 133 of each knob 130 is smaller than the outer diameter OD2 of the corresponding positioning column 153 of the positioning member 150. Before the spring 160 is mounted on the first knob column 133 and the positioning column 153, the inner diameter of the spring 160 is smaller than both the outer diameter OD1 of the first knob column 133 and the outer diameter OD2 of the positioning column 153. After the spring 160 is mounted on the first knob column 133 and the positioning column 153, the inner diameter of the first portion 161 of the spring 160 elastically expands radially to be substantially equal to the outer diameter OD1 of the first knob column 133, and the inner diameter of the second portion 162 of the spring 160 elastically expands radially to be substantially equal to the outer diameter OD2 of the positioning column 153.

[0038] Furthermore, the radial elastic expansion of the first portion 161 of the spring 160 is smaller than the radial elastic expansion of the second portion 162 of the spring 160. In a stationary state, the elastic restoring force of the first portion 161 of the spring 160 acting radially on the first knob column 133 can be regarded as the first portion 161 of the spring 160 generating a first interference amount on the first knob column 133, and the elastic restoring force of the second portion 162 of the spring 160 acting radially on the positioning column 153 can be regarded as the second portion 162 of the spring 160 generating a second interference amount on the positioning column 153 that is greater than the first interference amount.

[0039] During the rotation of each knob 130 relative to the corresponding positioning member 150, the second interference generated by the second portion 162 of the spring 160 on the positioning column 153 remains unchanged. In addition, as the first knob column 133 rotates relative to the first portion 161 of the spring 160, the radial elastic expansion of the first portion 161 of the spring 160 further increases, resulting in a slight decrease in the first interference, thereby facilitating the rotation of the knob 130.

[0040] In other examples, the outer diameter OD1 of the first knob column 133 of each knob 130 may be equal to the outer diameter OD2 of the positioning column 153 of the corresponding positioning member 150, so the radial elastic expansion of the first part 161 of the spring 160 is equal to the radial elastic expansion of the second part 162 of the spring 160. Accordingly, the first interference generated by the first part 161 of the spring 160 on the first knob column 133 is equal to the second interference generated by the second part 162 of the spring 160 on the positioning column 153.

[0041] like Figure 2A and Figure 2B As shown, in this embodiment, each knob 130 further includes a second knob portion 134 protruding from the first knob portion 133, and each positioning member 150 is provided with a second positioning groove 154 on the positioning portion 153. Specifically, each second knob portion 134 is slidably inserted into the corresponding second positioning groove 154. Through the engagement between the second knob portion 134 and the second positioning groove 154, the knob 130 can stably slide in a direction 102 parallel to the axis 101, such as up and down movement or vertical sliding. For example, the outer diameter OD3 of the second knob portion 134 is smaller than the outer diameter OD1 of the first knob portion 133.

[0042] In summary, in the display device of this invention, the operator can secure or release the panel assembly to the housing by simply turning a knob. This not only significantly improves the efficiency of panel assembly and disassembly, but also reduces the risk of damage during the assembly and disassembly process. Furthermore, the use of knobs instead of screws reduces the number of screws used, further embracing the principles of environmental protection and sustainable development.
