DETAILED DESCRIPTION

[0031] The following description provides many different embodiments or examples for implementing different features of the present invention. The components and arrangements described in the following specific examples are only used to simplify the present invention and are only used as examples, not to limit the present invention.

[0032] The present application embodiment provides a display screen installation structure, referring to Figures 1 to 11 As shown. The mounting structure includes a display screen 100, a middle frame 200, and at least one latch 300. The display screen 100 has a display function for displaying image information. The middle frame 200 serves as a mounting base, and the middle frame 200 has a mounting groove 211 for mounting the display screen 100. The display screen 100 is mounted in the mounting groove 211. The assembly direction of the display screen 100 and the middle frame 200 is defined as a first direction.

[0033] The middle frame 200 is also provided with a plug hole 212, which is communicated with the mounting groove 211, and the plug hole 212 is used for the plug pin 300 to pass through. The plug pin 300 is inserted into the plug hole 212 and extends into the display screen 100 located in the mounting groove 211, and the plug pin 300 is fixed to at least one of the display screen 100 and the middle frame 200. The plug pin 300 is inserted into the middle frame 200 and the display screen 100 at the same time, further fixing the relative position of the middle frame 200 and the display screen 100. In addition, the plug pin 300 can prevent the middle frame 200 and the display screen 100 from relative movement in the direction intersecting with the axial direction of the plug pin 300, thereby avoiding the positional offset between the two. When the latch 300 is assembled into the middle frame 200 and the display screen 100, the axial direction of the latch 300 is arranged to intersect with the first direction, so that the display screen 100 can be prevented from detaching from the middle frame 200 along the first direction, further improving the connection stability between the middle frame 200 and the display screen 100.

[0034] After the latch 300 is assembled into the middle frame 200 and the display screen 100, the latch 300 can only be taken out along its axial direction. Therefore, it is only necessary to avoid the axial direction of the latch 300 being the same as the first direction to ensure that the latch 300 can prevent the display screen 100 from detaching from the middle frame 200 and ensure the normal use of the display screen 100.

[0035] The more the number of the plugs 300 plugged into the middle frame 200, the better the position fixing effect of the display screen 100 and the middle frame 200. In some embodiments, the number of the plugs 300 is generally even, and they are symmetrically distributed on both sides of the display screen 100 to improve the connection stability between the display screen 100 and the middle frame 200. If the distribution of the plugs 300 is too concentrated, on the one hand, the fixing effect of the display screen 100 is poor, and on the other hand, a plurality of plug holes 212 are provided in one area of ​​the middle frame 200, which will reduce the structural strength of the middle frame 200, and the middle frame 200 is prone to deformation, affecting the normal use of the device.

[0036] The middle frame 200 is also provided with at least one device installation position, which is used to install a device, which may be a connector, a button or other structural member. When the device is in use, when pressing a button, plugging a device into a connector, or unplugging a device from a connector, the portion of the middle frame 200 corresponding to the device installation position will be subjected to more force than other portions, and this portion of the middle frame 200 is prone to deformation. The risk of debonding between the deformed middle frame 200 and the display screen 100 is higher. Therefore, in some embodiments of the present application, the latch 300 is disposed adjacent to the device installation position, as shown in FIG. Fig.10 As shown, due to the presence of the latch 300, the risk of debonding between the middle frame 200 and the display screen 100 can be reduced or avoided, thereby improving the overall structural stability of the endoscope device.

[0037] In some embodiments, the device mounting position includes a connector mounting hole 251, and the connector mounting hole 251 is mainly used to install the connector. Generally, there are multiple connector mounting holes 251, and the multiple connector mounting holes 251 are arranged side by side on one side of the middle frame 200. Figure 2 As shown. The connector mounting holes 251 are centrally arranged, which is more convenient for the use of the endoscope device. At least two plugs 300 are located on both sides of the plurality of connector mounting holes 251 arranged side by side, referring to Figure 8 As shown. With such a layout, on the one hand, it will not affect the normal arrangement of the multiple connector mounting holes 251, and the multiple connector mounting holes 251 can be arranged more compactly. On the other hand, after the connector is installed in the connector mounting hole 251, the connector will extend into the middle frame 200 to connect with the corresponding device, which makes it inconvenient to continue to install the plug 300 on the middle frame 200. Therefore, the plug 300 is generally provided on both sides of the connector mounting hole 251 to avoid the debonding of the middle frame 200 and the display screen 100 around the connector mounting hole 251. In the case where only one connector mounting hole 251 is provided, the plug 300 can be provided only on one side of the connector mounting hole 251, refer to Fig.10 As the number of connector mounting holes 251 increases, plug pins 300 may be provided on both sides of the plurality of connector mounting holes 251 .

[0038] In some other embodiments, the device installation position includes a button installation position 252, and the button installation position is used to install a button. The latch 300 is located at the middle of the length direction of the button installation position 252. Fig.10 and Fig.11 As shown. The button installed in the button installation position 252 is generally a sheet structure, and the installation of the button will not affect the installation of the latch 300. Therefore, the latch 300 and the button installation position 252 can be arranged at the same side position of the middle frame 200, and the latch 300 is located in the middle of the button installation position 252, and the latch 300 is used to offset the force applied to the middle frame 200 when the button is pressed, so as to prevent the middle frame 200 from being deformed.

[0039] In some embodiments of the present application, the middle frame 200 includes an inner frame 210 and an outer frame 220, the outer frame 220 is sleeved outside the inner frame 210, and is fixedly connected to the inner frame 210, and an anti-shrinkage rubber groove 230 is also provided between part of the outer frame 220 and the inner frame 210, Figure 2 , Figure 3 and Figure 7 The anti-shrinkage groove 230 can prevent the middle frame 200 from shrinking due to excessive size during the manufacturing process, and can improve the dimensional accuracy of the middle frame 200. The mounting groove 211 is provided in the inner frame 210, and the display screen 100 is installed in the inner frame 210.

[0040] The plug hole 212 can be provided in the outer frame 220, and the latch 300 can directly extend into the portion of the display screen 100 protruding from the mounting groove 211 after passing through the outer frame 220, or the latch 300 can extend into the display screen 100 after passing through the outer frame 220 and then through the inner frame 210. The plug hole 212 is provided in the outer frame 220, which is more conducive to assembling the latch 300, and at the same time, it is also convenient to observe the position of the latch 300 and judge whether the assembly position of the latch 300 is correct.

[0041] The plug hole 212 can also be set in the inner frame 210, and the plug hole 212 connects the anti-shrinkage rubber groove 230 and the installation groove 211. Figure 4 and Figure 5 As shown. The plug hole 212 is located in the inner frame 210, and there is no need to make a hole in the outer frame 220. The outer frame 220 has higher structural strength and better aesthetics. At the same time, the outer frame 220 can also protect the latch 300 to prevent external factors from affecting the position and structure of the latch 300. The anti-shrinkage rubber groove 230 provides an installation space for the latch 300. During the installation of the latch 300, even if the inner frame 210 is located inside, due to the presence of the anti-shrinkage rubber groove 230, the assembler can smoothly and conveniently insert the latch 300 into the plug hole 212 through the anti-shrinkage rubber groove 230. When the display screen 100 is installed in the installation groove 211, the groove structure on the display screen 100 for accommodating the latch 300 is aligned with the plug hole 212 to prepare for the insertion of the latch 300.

[0042] In some preferred embodiments, the inner frame 210 is further provided with an avoidance notch 213, the avoidance notch 213 is connected to the plug hole 212, and the avoidance notch 213 is located on one side of the notch of the plug hole 212 close to the anti-shrinkage rubber groove 230, Figure 6 and Figure 7 As shown. During the assembly of the latch 300, the latch 300 first enters the anti-shrinking rubber groove 230 through the notch of the anti-shrinking rubber groove 230, and then is inserted into the plug hole 212. During the insertion of the latch 300 into the plug hole 212, the smaller the angle between the axis of the latch 300 and the axis of the plug hole 212, the easier it is for the latch 300 to be inserted into the plug hole 212 and extend into the display screen 100. Therefore, the embodiment of the present application provides a larger activity space for the latch 300 by providing an avoidance notch 213 connected to the anti-shrinking rubber groove 230, so that the axis of the latch 300 can be parallel to the plug hole 212 as much as possible. In addition, the avoidance notch 213 is arranged closer to the notch of the anti-shrinking rubber groove 230, so that the avoidance notch 213 is on the insertion path of the latch 300, thereby expanding the activity space on the insertion path of the latch 300. If the avoidance gap 213 is located at a side of the plug hole 212 away from the notch of the anti-shrinkage rubber groove 230 , the avoidance gap 213 has almost no effect.

[0043] Further preferably, the avoidance notch 213 preferably passes through the inner frame 210 along the first direction toward the notch of the anti-shrinking rubber groove 230. Under such a layout, after the latch 300 is placed into the anti-shrinking rubber groove 230, the latch 300 can be directly placed in the larger activity space formed by the avoidance notch 213 and the anti-shrinking rubber groove 230, which is more convenient for the operator to control the position of the latch 300. In other embodiments, the avoidance notch 213 can also simultaneously connect the anti-shrinking rubber groove 230 and the installation groove 211, further expanding the activity space of the latch 300, and making it easier to install the latch 300.

[0044] After the latch 300 is installed in the middle frame 200 and the display screen 100, the latch 300 needs to be fixed to at least one of them, so as to fix the position of the latch 300 and prevent the latch 300 from being detached from the middle frame 200 and the display screen 100. The latch 300 is generally fixed by gluing, which is easier to operate and has a good fixing effect. In some preferred embodiments, the installation structure also includes a limit member 400, which is fixed to the middle frame 200 and is located in the anti-shrinkage glue groove 230, and is used to limit the position of the latch 300. When the latch 300 is inserted into the plug hole 212, the limit member 400 is tightly fitted with the latch 300, and is used to limit the position of the latch 300 in the axial direction of the latch 300 to prevent the latch 300 from being detached from the plug hole 212, refer to Figure 2 and Figure 3 Even if the connection between the latch 300 and the middle frame 200 and the connection between the latch 300 and the display screen 100 fail at the same time, the stopper 400 can always press against the latch 300 in the anti-shrinking rubber groove 230 to prevent the latch 300 from being separated from the middle frame 200.

[0045] The stopper 400 needs to limit the latch 300, and at least a part of the stopper 400 is located in the axial direction of the plug hole 212. In the process of assembling the latch 300, the stopper 400 is on the moving path of the latch 300, which will affect the assembly of the latch 300. In some embodiments of the present application, the stopper 400 is detachably connected to the middle frame 200. Before assembling the latch 300, the stopper 400 is removed to provide a larger operating space for the latch 300, so as to avoid the presence of the stopper 400 hindering the installation of the latch 300. After the assembly of the latch 300 is completed, the stopper 400 is installed to the middle frame 200 to limit the latch 300. In other embodiments of the present application, the stopper 400 is fixedly connected to the middle frame 200, and the two are even integrally formed structural parts. Under such a layout, the structure of the middle frame 200 is simpler and easier to process and manufacture. The limiter 400 is set as an elastic structural member, and the limiter 400 can be deformed under the action of external force. Therefore, in the process of assembling the latch 300, the latch 300 can be pressed against the limiter 400, so that the limiter 400 is deformed to provide installation space for the latch 300. After the latch 300 is installed, the force applied to the limiter 400 disappears, and the limiter 400 returns to the state before deformation. The force on the limiter 400 caused by the latch 300 detaching from the plug hole 212 is not enough to deform the limiter 400. The limiter 400 can limit the latch 300 and stabilize the position of the latch 300.

[0046] Preferably, in the first direction, the limiting member 400 is located at a side of the insertion hole 212 away from the notch of the anti-shrinkage rubber groove 230 , so as to further reduce the influence of the limiting member 400 on the installation of the latch 300 .

[0047] A plurality of reinforcing ribs 240 are fixed between the inner frame 210 and the outer frame 220. The reinforcing ribs 240 support the inner frame 210 and the outer frame 220 to improve the overall structural strength of the middle frame 200. Figures 8 to 11 As shown. It should also be noted that the reinforcing rib 240 needs to be arranged to avoid the plug hole 212, so as to prevent the reinforcing rib 240 from occupying the space of the anti-shrinkage rubber groove 230 corresponding to the plug hole 212. Further preferably, the plug hole 212 is arranged adjacent to one of the reinforcing ribs 240. Since the plug hole 212 is arranged on the inner frame 210, it will affect the structural strength of the inner frame 210 and reduce the structural strength of the inner frame 210. Therefore, the plug hole 212 is arranged adjacent to the reinforcing rib 240 to reduce the probability of deformation of the inner frame 210.

[0048] The embodiment of the present application also provides an endoscope device, including the display screen 100 installation structure provided in any of the above embodiments. In the device, the display screen 100 is stably connected to the middle frame 200. The endoscope device can be an all-in-one machine, a display device or a host, or other related electronic devices with a display screen 100 involved in the use of the endoscope.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
