[0033] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.
[0034] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the objects before and after are in an "or" relationship.
[0035] The display screen of the interactive electronic device of the endoscope, such as an all-in-one machine, a display, etc. can be built-in in the frame structure, and the whole is combined into a display module and installed in the device shell to obtain more favorable protection for the display screen. However, the inventors found in actual use that the existing first frame and second frame are usually assembled by clamping the clamping buckle and the clamping hole to fix and protect the display screen. Since the width of the clamping hole corresponding to the side wall of the frame is very small, the contact area of the clamping buckle and the clamping hole is small, and when used for a long time or subjected to a certain external force, the clamping buckle is easy to separate from the clamping hole, and then the first frame and the second frame are easy to separate, which causes the display screen to easily fall off.
[0036] The frame structure 100, the electronic device 300 and the endoscope system provided by the present application will be described in detail below in combination with the accompanying drawings and specific embodiments and application scenarios. Figures 1 to 15 The frame structure 100, the electronic device 300 and the endoscope system provided by the present application will be described in detail below in combination with the accompanying drawings and specific embodiments and application scenarios.
[0037] Some embodiments of the present application provide a frame structure 100, comprising a first frame 110 and a second frame 120.
[0038] As shown in Figure 2 , Figure 4 , Figure 8 and Figure 10 , the first frame 110 comprises a first clamping buckle 111, and the second frame 120 comprises a first clamping recess 121. The first frame 110 and the second frame 120 are assembled by clamping the first clamping buckle 111 and the first clamping recess 121, and form a receiving space for placing the display screen 200. By clamping the first frame 110 and the second frame 120, the display screen 200 is built-in in the frame structure 100, and the whole is combined into a display module and installed in the device shell, thereby obtaining more favorable protection for the display screen 200.
[0039] It should be noted that the first clamping recess 121 can be a through hole structure or a groove structure, and both can realize clamping cooperation with the first clamping portion 111. Here, it can be flexibly set according to the use requirement, and the embodiment does not limit this.
[0040] As shown in Figure 8 and Figure 10 , the second frame 120 further includes a clamping protrusion 122, which is arranged on the opposite side of the first clamping recess 121 to be limited by the clamping protrusion 122 when the first clamping portion 111 is clamped in the first clamping recess 121; wherein the opposite side of the first clamping recess 121 is the side of the first clamping recess 121 for the first clamping portion 111 to be clamped in.
[0041] The clamping protrusion 122 forms a mechanical limiting structure on the opposite side of the first clamping recess 121, and forms a constraint with the first clamping portion 111 during clamping. Compared with the frame structure in the prior art which adopts the cooperation mode of clamping buckles and clamping holes, the clamping buckles are easily separated from the clamping holes due to horizontal movement. However, in the frame structure 100 of the embodiment, the clamping protrusion 122 protrudes towards the first clamping portion 111, thereby increasing the contact area with the first clamping portion 111. Therefore, the first clamping portion 111 needs to move a large distance horizontally to be separated from the clamping protrusion 122, thereby improving the stability of the clamping of the first clamping portion 111 and the first clamping recess 121, and optimizing the anti-disengagement performance of the frame structure 100.
[0042] In some embodiments, as shown in Figure 2 and Figure 10 , the clamping protrusion 122 is formed by bending the corresponding part of the second frame 120. The clamping protrusion 122 is formed by bending the corresponding part of the second frame 120, without the need for additional materials or components, directly utilizing the structure of the second frame 120 itself to realize the limiting function, with simple process and low cost. Moreover, the clamping protrusion 122 formed by bending maintains material continuity with the second frame 120, avoiding the risk of weakening introduced by welding or assembly, and the overall structure is lightweight. At the same time, the arc transition of the bent part can disperse stress and reduce local stress concentration, thereby increasing the structural strength of the second frame 120.
[0043] In some embodiments, the clamping protrusion 122 is formed by thickening the corresponding part of the second frame 120. The clamping protrusion 122 is formed by locally thickening the corresponding part of the second frame 120, which can specifically enhance the compression strength and rigidity of the clamping protrusion 122. The clamping protrusion 122 formed by thickening process (such as stamping thickening or casting) has larger volume, and the contact area with the first clamping portion 111 is increased, thereby optimizing the friction limiting effect and further enhancing the stability of the assembly of the first frame 110 and the second frame 120.
[0044] As shown in Figure 3 and Figure 14 , the first frame 110 includes a plurality of first circumferential side walls 112 arranged in a circumferential direction, and the plurality of first circumferential side walls 112 are connected end to end in the circumferential direction of the first frame 110. The plurality of first circumferential side walls 112 form a closed loop structure by being connected end to end, significantly improving the deformation resistance of the first frame 110, and the circumferentially arranged first circumferential side walls 112 convert external loads into a ring-shaped stress transmission path, avoiding the risk of fracture caused by local stress concentration.
[0045] As shown in Figure 4 and Figure 8 , the first buckle part 111 is provided on the first circumferential side wall 112. By providing the first buckle part 111 on the first circumferential side wall 112, the clamping force generated during the assembly of the first frame 110 and the second frame 120 is transmitted through the first circumferential side wall 112, avoiding local stress concentration.
[0046] and / or, as shown in Figure 9 , the second frame 120 includes a plurality of second circumferential side walls 123 arranged in a circumferential direction, and the plurality of second circumferential side walls 123 are connected end to end in the circumferential direction of the second frame 120. The plurality of second circumferential side walls 123 form a closed loop structure by being connected end to end, significantly improving the deformation resistance of the second frame 120, and the circumferentially arranged second circumferential side walls 123 convert external loads into a ring-shaped stress transmission path, avoiding the risk of fracture caused by local stress concentration.
[0047] Among them, as preferred in this embodiment, the first frame 110 is provided with the first circumferential side wall 112, and the second frame 120 is provided with the second circumferential side wall 123, so that the clamping force generated by the clamping of the first buckle part 111 and the first clamping recess 121 can be transmitted through the first circumferential side wall 112 and the second circumferential side wall 123 respectively, to avoid stress concentration.
[0048] As shown in Figure 8 and Figure 10 , the first clamping recess 121 and the clamping protrusion 122 are provided on the second circumferential side wall 123. By providing the first clamping recess 121 and the clamping protrusion 122 on the second circumferential side wall 123, the clamping force generated during the assembly of the first frame 110 and the second frame 120 is transmitted through the second circumferential side wall 123, avoiding local stress concentration.
[0049] As shown in Figure 3 and Figure 14As shown, the joint of the first peripheral side wall 112 is provided with a first notch structure 113. The first notch structure 113 is arranged at the joint of the plurality of first peripheral side walls 112, which not only ensures the structural strength of the first peripheral side wall 112, but also makes the first peripheral side wall 112 have a certain deformation ability. In the process of assembling the first frame 110 and the second frame 120, the first peripheral side wall 112 can be deformed in the process of the clamping protrusion 122 contacting the first clamping portion 111 due to the existence of the first notch structure 113, which improves the smoothness of the first clamping portion 111 passing through the clamping protrusion 122, facilitates the clamping of the first clamping portion 111 into the first clamping recess 121, and further reduces the assembly difficulty.
[0050] As preferred in the embodiment, the joint of the first peripheral side wall 112 is located at the corner of the first frame 110. The joint of the first peripheral side wall 112 is arranged at the corner of the first frame 110, which fully utilizes the geometric rigidity and structural strength of the corner area, so that the joint can uniformly disperse the load from different directions and reduce the risk of stress concentration.
[0051] As shown in Figure 3 and Figure 14 , the depth of the first notch structure 113 is less than the height of the first peripheral side wall 112. By making the depth of the first notch structure 113 less than the height of the first peripheral side wall 112, the first peripheral side wall 112 at the position provided with the first notch structure 113 still has a partial connection, which makes the first peripheral side wall 112 not only can convert external load into an annular stress transmission path to avoid stress concentration, but also has a deformation ability to reduce the assembly difficulty of the first frame 110 and the second frame 120.
[0052] and / or, as shown in Figure 9 , the joint of the second peripheral side wall 123 is provided with a second notch structure 125. The second notch structure 125 is arranged at the joint of the plurality of second peripheral side walls 123, which not only ensures the structural strength of the second peripheral side wall 123, but also makes the second peripheral side wall 123 have a certain deformation ability. In the process of assembling the first frame 110 and the second frame 120, the second peripheral side wall 123 can be deformed in the process of the clamping protrusion 122 contacting the first clamping portion 111 due to the existence of the second notch structure 125, which improves the smoothness of the first clamping portion 111 passing through the clamping protrusion 122, facilitates the clamping of the first clamping portion 111 into the first clamping recess 121, and further reduces the assembly difficulty.
[0053] As preferred in the embodiment, the joint of the second peripheral side wall 123 is located at the corner of the second frame 120. By arranging the joint of the second peripheral side wall 123 at the corner of the second frame 120, the geometric rigidity and structural strength of the corner area are fully utilized, so that the joint can uniformly disperse loads from different directions and reduce the risk of stress concentration.
[0054] As shown in Figure 9 , the depth of the second notch structure 125 is less than the height of the second peripheral side wall 123. By making the depth of the second notch structure 125 less than the height of the second peripheral side wall 123, the second peripheral side wall 123 at the position where the second notch structure 125 is arranged still has a partial connection, which makes the second peripheral side wall 123 not only capable of converting external loads into an annular stress transmission path to avoid stress concentration, but also has a deformation capability, thereby reducing the assembly difficulty of the second frame 120 and the second frame 120.
[0055] As shown in Figure 6 and Figure 15 , the first peripheral side wall 112 and / or the second peripheral side wall 123 is formed by bending to form a wiring notch 116. By bending the first peripheral side wall 112 and / or the second peripheral side wall 123 to form the wiring notch 116, no additional holes or cuts are needed, which not only maintains the integrity of the first peripheral side wall 112 and / or the second peripheral side wall 123 to avoid local strength weakening and notch edge wear on the wire caused by notch processing, but also naturally transitions by bending to disperse stress and increase the structural strength of the first peripheral side wall 112 and / or the second peripheral side wall 123.
[0056] As shown in Figure 5 , the first frame 110 is further provided with one of a second buckle portion 114 and a second clamping recess 124, the second frame 120 is provided with the other one, and the first frame 110 and the second frame 120 are further assembled by clamping of the second buckle portion 114 and the second clamping recess 124. During assembly of the first frame 110 and the second frame 120, clamping of the first buckle portion 111 and the first clamping recess 121 and clamping of the second buckle portion 114 and the second clamping recess 124 are combined to achieve assembly of the first frame 110 and the second frame 120.
[0057] It should be noted that the second clamping recess 124 can be a through hole structure or a non-through slot structure, both of which can achieve clamping cooperation with the second buckle portion 114, which can be flexibly arranged according to use requirements, and the embodiment does not limit this.
[0058] In some embodiments, the first frame 110 is provided with the second buckle portion 114, and the second frame 120 is provided with the second clamping recess 124.
[0059] In some embodiments, the first frame 110 is provided with a second clamping recess 124, and the second frame 120 is provided with a second clamping portion 114.
[0060] As preferred in the present embodiment, the first peripheral wall 112 is provided with one of the second clamping portion 114 and the second clamping recess 124, and the second peripheral wall 123 is provided with the other one. The force generated in the cooperation of the second clamping portion 114 and the second clamping recess 124 is transmitted through the first peripheral wall 112 and the second peripheral wall 123, avoiding local stress concentration.
[0061] As shown in Figure 5 and Figure 8 , the width dimension of the second clamping portion 114 is smaller than the width dimension of the first clamping portion 111. Since the apposed side of the first clamping recess 121 clamped and cooperated with the first clamping portion 111 has the clamping protrusion 122, it will cause certain difficulty in the assembly of the first frame 110 and the second frame 120. Therefore, by making the width dimension of the second clamping portion 114 smaller than the width dimension of the first clamping portion 111, the narrower second clamping portion 114 realizes the pre-orientation positioning, preferentially guides the initial alignment of the first frame 110 and the second frame 120, makes the second clamping portion 114 first avoid the interference of the clamping protrusion 122 by elastic deformation, provides a space allowance for the subsequent accurate clamping of the first clamping portion 111 into the first clamping recess 121, and thus reduces the installation difficulty of the first frame 110 and the second frame 120.
[0062] Among them, the width dimension of the first clamping portion 111 is shown as W1 in Figure 8 , and the width dimension of the second clamping portion 114 is shown as W2 in Figure 5 .
[0063] As shown in Figure 3 , Figure 9 and Figure 11 , one of the first frame 110 and the second frame 120 is provided with a window 126 for displaying the display screen 200, and the other is provided with a supporting portion 115 for supporting the display screen 200, and the supporting surface of the supporting portion 115 is arranged towards the window 126. The supporting portion 115 supports the display screen 200 so that the display surface of the display screen 200 faces the window 126 to play the picture. Moreover, the supporting portion 115 supports the display screen 200 at the same time, and also makes the back surface of the display screen 200 and the first frame 100 have a gap for heat dissipation and wiring.
[0064] As preferred in the embodiment, the support part 115 supports the display screen 200 and makes the display surface of the display screen 200 abut against the inner wall of the window 126. The support part 115 provides a rigid support surface, so that the display surface of the display screen 200 abuts against the inner wall of the window 126, eliminates the assembly gap and prevents the display screen 200 from being displaced, thereby better fixing and protecting the display screen 200.
[0065] As shown in Figure 3 , Figure 11 and Figure 14 , at least one side wall of the support part 115 extends towards and is connected with the first or second peripheral side wall 112 or 123 opposite to it. By connecting the at least one side wall of the support part 115 with the first or second peripheral side wall 112 or 123, the first or second peripheral side wall 112 or 123 originally independent is integrated with the support part 115 as a whole, thereby significantly improving the structural strength of the first or second peripheral side wall 112 or 123.
[0066] As shown in Figure 12 , the first frame 110 has a first positioning hole 1121, and the second frame 120 has a second positioning hole 1231 corresponding to the first positioning hole 1121; the first frame 110 and the second frame 120 are connected by a positioning pin passing through the first positioning hole 1121 and the second positioning hole 1231. By precisely aligning the first positioning hole 1121 and the second positioning hole 1231 and the penetration of the positioning pin, the hole-pin mechanical interlocking is used to fix the first frame 110 and the second frame 120. The close contact between the positioning pin and the hole wall inhibits the relative displacement between the first frame 110 and the second frame 120, ensures the uniform stress on the connection interface, and significantly improves the anti-vibration and load stability of the frame structure 100.
[0067] In some embodiments, the window 126 is arranged on the first frame 110, the support part 115 is arranged on the second frame 120, at least one side wall of the support part 115 is connected with the second peripheral side wall 123, and the second positioning hole 1231 extends into the support part 115. By extending the second positioning hole 1231 into the support part 115, the positioning pin is connected with the support part 115, thereby greatly improving the pull-out and shear resistance of the connection position.
[0068] In some embodiments, the window 126 is arranged on the second frame 120, the support part 115 is arranged on the first frame 110, at least one side wall of the support part 115 is connected with the first peripheral side wall 112, and the first positioning hole 1121 extends into the support part 115. By extending the first positioning hole 1121 into the support part 115, the positioning pin is connected with the support part 115, thereby greatly improving the pull-out and shear resistance of the connection position.
[0069] As shown in Figure 4 and Figure 8 The outer wall of the first buckle part 111 in the carding cooperation with the first carding recess 121 is provided with a first guide structure 1111 for guiding the first carding recess 121 to pass through the first buckle part 111. By setting the first guide structure 1111 with a guide slope or an arc transition surface on the carding side of the first buckle part 111, the difficulty of assembling the first carding recess 121 with the first buckle part 111 is reduced by progressive guidance.
[0070] and / or, as shown in Figure 5 The outer wall of the second buckle part 114 in the carding cooperation with the second carding recess 124 is provided with a second guide structure 1141 for guiding the second carding recess 124 to pass through the second buckle part 114. By setting the second guide structure 1141 with a guide slope or an arc transition surface on the carding side of the second buckle part 114, the difficulty of assembling the second carding recess 124 with the second buckle part 114 is reduced by progressive guidance.
[0071] Some embodiments of the present application also provide an electronic device 300, as shown in Figure 1 and Figure 13 The electronic device 300 comprises a display screen 200 and a frame structure 100.
[0072] As shown in Figure 1 The display screen 200 is fixed in the frame structure 100, and the whole combination is installed in the device shell as a display module to obtain more favorable protection for the display screen 200.
[0073] The electronic device 300 can be an all-in-one machine, a display, a tablet, a POS machine, a television, etc., and the present embodiment does not limit it.
[0074] Some embodiments of the present application also provide an endoscope system comprising the electronic device 300. When the electronic device 300 is used for the endoscope system, the electronic device 300 is a device for interacting with the endoscope. After the insertion part of the endoscope is placed in the patient's body, the image information of the target part (such as a lesion) can be obtained through the camera at the front end of the insertion part, and the image information is transmitted to the rear-end interactive electronic device 300 to display the image.
