Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic equipment, and in particular to a shell assembly, an endoscope handle, and an assembly method of the endoscope handle. BACKGROUND

[0002] An endoscope is a commonly used medical instrument, which is an inspection instrument capable of directly entering a natural duct of a human body to provide sufficient diagnostic information for a doctor to treat a disease. The endoscope includes an insertion part and an operation part. The insertion part is arranged in the operation part to be operated by the operation part. Specifically, the insertion part can be inserted into the body through a body cavity or a surgical incision by operating the operation part.

[0003] In the related art, the operation part includes a shell and a circuit board arranged in the shell. The shell includes an upper shell and a lower shell. The upper shell is buckled to the lower shell to form a receiving cavity. The circuit board is arranged in the receiving cavity and is limitedly matched with a limiting groove arranged in the upper shell and the lower shell. However, during assembly of the operation part, it is difficult to insert the circuit board into the limiting groove arranged in the upper shell and the lower shell, which results in low assembly efficiency. SUMMARY

[0004] The present application discloses a shell assembly, an endoscope handle, and an assembly method of the endoscope handle to solve the problem of difficulty in positioning the circuit board during assembly of the upper and lower shells in the shell assembly in the related art.

[0005] To solve the above problems, the present application adopts the following technical solutions:

[0006] In a first aspect, the present application provides a shell assembly. The shell assembly includes a first shell and a second shell. The first shell includes a first mounting portion and a first support portion arranged at intervals. The first mounting portion has a first mounting groove for mounting a circuit board. The second shell is configured to be coverable on the first shell. The second shell includes a second support portion. The circuit board has a first side and a second side opposite to each other in a first direction. In the case where the first shell and the second shell are covered, the first mounting portion and the first support portion are supported on the first side of the circuit board, and at least part of the circuit board is located in the first mounting groove. The second support portion is supported on the second side of the circuit board. In the first direction, a projection of the second support portion on the first side of the circuit board is located between the first mounting portion and the first support portion. During covering of the first shell and the second shell, the first support portion can push the circuit board to rotate around the first support portion.

[0007] The technical solutions adopted by the present application can achieve the following beneficial effects:

[0008] In the shell assembly, the first shell and the second shell can provide support for the circuit board during the process of being closed, so that the circuit board can rotate around the second support. During the process of closing the first shell on the second shell, the first support in the first shell can be first moved to the side away from the first mounting portion to approach the second shell, and then the first support can be first abutted with the circuit board. The projection of the second support on the first side of the circuit board is located between the first mounting portion and the first support. Therefore, the force acting on the circuit board by the first support can be converted into a torque for promoting the rotation of the circuit board around the first support, so that the circuit board rotates around the first support, and the end of the circuit board adjacent to the first mounting portion is moved to the direction close to the first shell. In this way, it is beneficial to reduce the distance between the circuit board and the first mounting portion, and then it is beneficial to align the circuit board with the first mounting slot on the first mounting portion, and to reduce the installation difficulty of the circuit board.

[0009] In a second aspect, the present application provides an endoscope handle. The endoscope handle includes a circuit board and the shell assembly provided above. Wherein the circuit board has a first side and a second side opposite to each other. The first side of the circuit board is abutted with the first mounting portion and the first support of the first shell. And at least part of the circuit board is located in the first mounting slot. The second side of the circuit board is abutted with the second support of the second shell. The second side of the circuit board is abutted with the second support.

[0010] The endoscope handle provided by the present application has the same technical features as the shell assembly provided by the present application, and can achieve the same technical effects. Therefore, it will not be described here.

[0011] In a third aspect, the present application provides an assembly method of an endoscope handle. The assembly method of the endoscope handle can be used to assemble the endoscope handle provided by the present application.

[0012] The assembly method of the endoscope handle includes: assembling the circuit board to the second shell, and supporting the circuit board on the second support; aligning and abutting the side of the first shell away from the first mounting portion with the second shell; rotating the first shell to the side close to the second shell with the abutting place of the first shell and the second shell as the center, until the circuit board rotates around the first support; aligning the first side of the circuit board with the first mounting slot; rotating the first shell to the side close to the second shell with the abutting place of the first shell and the second shell as the center, until the first shell is closed with the second shell.

[0013] The endoscope handle assembly method provided by the application comprises the following steps: abutting the first shell and the second shell, and taking the abutting position as the center of relative rotation of the first shell and the second shell, so that the first supporting part in the first shell is supported on the first side of the circuit board before the first mounting part. Further, rotating the first shell around the abutting position of the first shell and the second shell, so that one end of the circuit board adjacent to the first mounting part is deflected to the side close to the first shell, thereby facilitating the alignment of the circuit board and the first mounting groove of the first mounting part, so as to facilitate the embedding of the circuit board into the first mounting groove. Therefore, the endoscope handle assembly method is beneficial to reduce the assembly difficulty of the endoscope handle. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0032] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0033] The terms "first", "second", and the like in the description and in the claims of the present application are used to distinguish similar objects, and are not used to describe a particular sequential or chronological order. It should be understood that the data thus used can be interchanged, where appropriate, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and are not limited in number, 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 front and rear associated objects are in a "or" relationship.

[0034] In the related art, during the installation of the upper shell and the lower shell, the circuit board and the limiting slot in the upper shell are not aligned, which causes the upper shell and the lower shell to be unable to be closed during the process. Or, during the closing of the upper shell and the lower shell, the side of the circuit board close to the upper shell cannot be embedded into the limiting slot on the upper shell, so that the circuit board can shake relative to the upper shell and / or the lower shell, which is easy to damage other components in the shell or damage the electronic devices on the circuit board. Although the relative positions of the upper shell and the lower shell can be adjusted during the closing of the upper shell and the lower shell to make the slot opening of the limiting slot on the upper shell relative to the circuit board. However, during the alignment process, the upper shell and the lower shell have been basically closed, and it is not convenient to observe the relative position of the circuit board and the limiting slot, thereby increasing the difficulty of assembling the upper shell and the lower shell.

[0035] To solve the above problems, the present application provides a shell assembly, an endoscope handle and an assembly method of the endoscope handle. The shell assembly includes a first shell and a second shell configured to be closed with the first shell to form an installation space. The first shell is provided with a mounting portion and a supporting portion. The second shell is provided with a supporting portion. In the case where the first shell and the second shell are closed, the supporting portion on the second shell supports the part of the circuit board between the mounting portion and the supporting portion of the first shell. In this way, during the installation of the circuit board, the supporting portion of the first shell can be supported on the circuit board before the mounting portion of the first shell by adjusting the posture of the first shell and the second shell during the closing process. Therefore, the end of the circuit board adjacent to the mounting portion of the first shell will be tilted towards the end close to the first shell, thereby reducing the difficulty of aligning the circuit board with the mounting portion on the first shell. Therefore, the shell assembly is beneficial to solve the problem of large alignment difficulty of the circuit board in the assembly process of the upper and lower shells in the related art shell assembly.

[0036] The shell assembly, the endoscope handle and the assembly method of the endoscope handle provided by the embodiments of the present application will be described in detail below in combination with the specific embodiments and application scenarios. Figures 1 to 15 The shell assembly, the endoscope handle and the assembly method of the endoscope handle provided by the embodiments of the present application will be described in detail below in combination with the specific embodiments and application scenarios.

[0037] In a first aspect, a housing assembly is provided. The housing assembly includes a first housing 100 and a second housing 200. Referring to Figure 1 , Figure 3 and Figure 4 , the first housing 100 includes a first mounting portion 110 and a first support portion 120. The first mounting portion 110 has a first mounting slot 111 for mounting a circuit board 300. The second housing 200 is configured to be coverable on the first housing 100. The second housing 200 includes a second support portion 210.

[0038] Referring to Figure 3 , in some optional embodiments, the first housing 100 and the second housing 200 each has a receiving slot. For example, the first support portion 120 and the first mounting portion 110 are disposed in the receiving slot of the first housing 100. The second support portion 210 is disposed in the receiving slot of the second housing 200. In optional embodiments, the first housing 100 and the second housing 200 are coverable to form a receiving space. The circuit board 300 is disposed in the receiving space formed by the first housing 100 and the second housing 200.

[0039] According to some optional embodiments, as shown in Figure 3 , the circuit board 300 has a first side and a second side opposite to each other in a first direction. Optionally, the first direction can be a direction in which the first housing 100 and the second housing 200 are coverable. For example, the first direction can be a direction indicated by a y-axis in Figure 3 or Figure 9 . Referring to Figure 9 , in some optional embodiments, when the first housing 100 and the second housing 200 are coverable, the first mounting portion 110 and the first support portion 120 are supported on the first side of the circuit board 300, and at least a portion of the circuit board 300 is located in the first mounting slot 111. The second support portion 210 is supported on the second side of the circuit board 300. In the first direction, a projection of the second support portion 210 on the first side of the circuit board 300 is located between the first mounting portion 110 and the first support portion 120.

[0040] For example, a portion of the circuit board 300 abutting against the first support portion 120 is a first sub-portion. A portion of the circuit board 300 abutting against the first mounting portion 110 is a second sub-portion. A portion of the circuit board 300 abutting against the second support portion 210 is a third sub-portion. Optionally, the third sub-portion is located between the first sub-portion and the second sub-portion. During the process of coverability of the first housing 100 and the second housing 200, the first support portion 120 can push the circuit board 300 to rotate around the first support portion 120.

[0041] For example, during the process of covering the first housing 100 with the second housing 200, the circuit board 300 is first installed in the second housing 200. Then the first housing 100 is moved to be close to the second housing 200 at the side of the first housing 100 away from the first mounting portion 110, so that the first support portion 120 can be supported on the circuit board 300 before the first mounting portion 110, and then the first support portion 120 pushes the circuit board 300 to rotate around the first support portion 120.

[0042] The above embodiment provides a housing assembly, during the process of covering the first housing 100 with the second housing 200, the first support portion 120 pushes the circuit board 300 in the second housing 200 to rotate around the second support portion 210 relative to the second housing 200, and then the circuit board 300 can be deflected to the side close to the first mounting portion 110, so as to reduce the distance between the circuit board 300 and the first mounting slot 111. Since the distance between the circuit board 300 and the first mounting slot 111 is smaller during the process of aligning the circuit board 300 with the first mounting slot 111, the alignment is simpler and more accurate. Therefore, the embodiment is beneficial to reduce the difficulty of aligning the circuit board 300 with the first mounting slot 111.

[0043] In addition, the housing assembly can use the deflection of the circuit board 300 to the side of the first mounting portion 110, so that during the process of aligning the circuit board 300 with the first mounting slot 111, the gap between the first housing 100 and the second housing 200 is larger, so as to facilitate the observation of the relative position between the circuit board 300 and the first mounting slot 111, and to reduce the difficulty of aligning the circuit board 300 with the first mounting slot 111.

[0044] In some optional embodiments, as shown in Figure 9 The second housing 200 further includes a second mounting portion 220. In the case of covering the first housing 100 with the second housing 200, the second mounting portion 220 supports the second side of the circuit board 300. In the first direction, the projection of the second mounting portion 220 on the first side of the circuit board 300 is close to the side of the projection of the second support portion 210 on the first side of the circuit board 300 close to the first mounting portion 110. The second mounting portion 220 has a second mounting slot 221, and at least part of the circuit board 300 is located in the second mounting slot 221 during the process of covering the second housing 200 with the first housing 100.

[0045] In the above embodiments, the second mounting groove 221 can provide a limit for the circuit board 300, improving the stability of the circuit board 300 mounted on the second housing 200. Furthermore, during the assembly of the housing assembly, the second mounting groove 221 can maintain the orientation of the circuit board 300 relative to the second housing 200, which helps prevent the circuit board 300 from tilting relative to the second housing 200 during assembly. This allows the circuit board 300 to align with the opening of the first mounting groove 111 by adjusting the relative positions of the first housing 100 and the second housing 200, thus reducing the assembly difficulty of the housing assembly.

[0046] Reference Figure 9 In some optional embodiments, the first mounting portion 110 and the second mounting portion 220 are arranged along the direction in which the first housing 100 and the second housing 200 close together. For example, the direction in which the first housing 100 and the second housing 200 close together is... Figure 9 The direction described by the y-axis. For example, a first mounting groove 111 is disposed on the side of the first mounting portion 110 adjacent to the first support portion 120 along the direction in which the first housing 100 and the second housing 200 cover each other, and the first mounting groove 111 extends through one end of the first mounting portion 110 adjacent to the second housing 200, so that the circuit board 300 can be embedded in the first mounting groove 111. A second mounting groove 221 is disposed on the second mounting portion 220 along the direction in which the first housing 100 and the second housing 200 cover each other, and the second mounting groove 221 extends through one end of the second mounting portion 220 adjacent to the first housing 100, so that the circuit board 300 can be embedded in the second mounting groove 221.

[0047] In some alternative embodiments, when the first housing 100 and the second housing 200 are closed, at least a portion of the circuit board 300 abuts against the bottom of the first mounting groove 111 to improve the stability of the assembly of the circuit board 300 with the first housing 100, thereby helping to prevent the circuit board 300 from shaking within the housing assembly.

[0048] According to some optional embodiments, such as Figure 10 and Figure 11 As shown, the second support portion 210 has a third mounting groove 211 on the side adjacent to the second mounting portion 220. Exemplarily, the second support portion 210 is arranged in the direction in which the first housing 100 and the second housing 200 overlap. The third mounting groove 211 extends through one end of the second support portion 210 adjacent to the first housing 100 in the direction in which the first housing 100 and the second housing 200 overlap, so that the circuit board 300 can be embedded in the third mounting groove 211.

[0049] In the above embodiments, the third mounting slot 211 can pre-position the circuit board 300 during the assembly of the housing assembly, thereby reducing the difficulty of positioning and installing the circuit board 300 with the first housing 100 and the second housing 200.

[0050] Exemplarily, during the assembling of the housing assembly, the circuit board 300 is assembled to the second support portion 210. Specifically, at least a part of the circuit board 300 is embedded into the third mounting slot 211, so that the circuit board 300 can be supported at a preset position of the second support portion 210, thereby facilitating the alignment of the circuit board 300 with the first mounting slot 111 of the first mounting portion 110 during the covering of the first housing 100 and the second housing 200.

[0051] Referring to Figure 7 and Figure 8 , the circuit board 300 comprises a first section 310 and a second section 320 connected to the first section 310. The second side of the first section 310 protrudes from the second side of the second section 320. Referring to Figure 9 In some optional embodiments, the first section 310 and the second section 320 can be distributed along a second direction. Exemplarily, the second direction can be the direction indicated by the x-axis in Figure 9 .

[0052] Exemplarily, the first side of the first section 310 and the first side of the second section 320 are flush. The width of the first section 310 in the first direction is a first width, and the width of the second section 320 in the first direction is a second width. The first width is greater than the second width, so that the second side of the first section 310 protrudes from the second side of the second section 320.

[0053] In the above embodiments, the second side of the first section 310 protrudes from the second side of the second section 320, i.e., an avoiding gap 301 can be formed on the second side of the circuit board 300. In this way, during the rotation of the circuit board 300 around the second support portion 210, the end of the second section 320 away from the first section 310 can be prevented from interfering with the first housing 100.

[0054] In other optional embodiments, the second support portion 210 is a protruding structure arranged on the inner wall of the second housing 200, so that the side of the second support portion 210 away from the second mounting portion 220 can form an avoiding space for the rotation of the circuit board 300 around the second support portion 210.

[0055] Referring to Figure 9 , in some optional embodiments, the end of the first section 310 away from the second section 320 is at least partially embedded into the second mounting slot 221. The end of the first section 310 adjacent to the second section 320 is at least partially located in the third mounting slot 211.

[0056] In the above embodiments, the two ends of the first section 310 in the second direction can be respectively embedded in the second mounting slot 221 and the third mounting slot 211, thereby benefiting the stability of the assembly of the circuit board 300 and the second housing 200. Moreover, the first section 310 is embedded in the second mounting slot 221 and the third mounting slot 211, thereby the second mounting slot 221 and the third mounting slot 211 can be used to guide the rotation of the circuit board 300 around the second support portion 210, which is beneficial to prevent the circuit board 300 from tilting to one side of its width during the process of covering the first housing 100 and the second housing 200, thereby aligning the circuit board 300 with the first mounting slot 111 during the process of covering the first housing 100 and the second housing 200.

[0057] According to some optional embodiments, referring to Figure 10 and Figure 11 , the bottom of the third mounting slot 211 has a protruding portion 212. For example, in the case of covering the first housing 100 and the second housing 200, the protruding portion 212 is located between the first side and the second side of the circuit board 300. Figure 8 and Figure 9 .

[0058] Referring to Figures 3 to 9 , the protruding portion 212 protrudes from the bottom of the third mounting slot 211. Referring to Figure 4 , during the process of covering the first housing 100 and the second housing 200, the second side of the first section 310 abuts against the protruding portion 212. As shown in Figures 5 to 8 , in the case that one end of the first section 310 adjacent to the second section 320 abuts against the bottom wall of the third mounting slot 211, the first section 310 can slide along the protruding portion 212 to the side away from the bottom of the third mounting slot 211 until the end wall of the first section 310 adjacent to the second section 320 abuts against the protruding portion 212.

[0059] In the housing assembly provided by the above embodiments, the circuit board 300 can be assembled in the third mounting slot 211 first, and supported on the second side of the circuit board 300 by the protruding portion 212. For example, in the case where the protruding portion 212 supports the second side of the circuit board 300, the portion of the circuit board 300 embedded in the third mounting slot 211 has a first width in the first direction. In the case where the first housing 100 and the second housing 200 are closed, the portion of the circuit board 300 embedded in the third mounting slot 211 has a second width in the first direction. The second width is greater than the first width. During the assembly of the first housing 100 and the second housing 200, the circuit board 300 is assembled into the third mounting slot 211 so that the second side of the circuit board 300 abuts against the protruding portion 212. This not only helps to ensure that the first support portion 120 abuts against the first side of the circuit board 300 before the first mounting portion 110, but also increases the height of the circuit board 300 protruding from the second housing 200. Therefore, this embodiment helps to reduce the difficulty of aligning the circuit board 300 with the first mounting slot 111.

[0060] According to some optional embodiments, as shown in Figure 9 The first mounting slot 111 is arranged on the side of the first mounting portion 110 adjacent to the first support portion 120. In the case where the first housing 100 and the second housing 200 are closed, the bottom of the first mounting slot 111 abuts against the end surface of the end of the circuit board 300 away from the first support portion 120, and the sidewall of the first mounting slot 111 abuts against the first side of the circuit board 300.

[0061] In the above embodiments, the first mounting portion 110 can abut against the end of the first section 310 away from the second section 320, which helps to improve the stability of the assembly of the circuit board 300 and the first housing 100, and further helps to prevent the circuit board 300 from shaking in the housing assembly.

[0062] In some optional embodiments, in the case where the first housing 100 and the second housing 200 are closed, the bottom of the first mounting slot 111 abuts against the end surface of the end of the circuit board 300 away from the first support portion 120. The bottom of the third mounting slot 211 abuts against the end surface of the end of the first section 310 adjacent to the second section 320. In this way, the first housing 100 and the second housing 200 can limit the circuit board 300 from all sides, which helps to prevent the circuit board 300 from shaking in the housing assembly, and further helps to improve the stability of the assembly of the circuit board 300 and the housing assembly.

[0063] In some optional embodiments, referring to Figure 1 and Figure 2The first shell 100 further comprises a first positioning portion 130. The first positioning portion 130 is located on a side of the first supporting portion 120 away from the first mounting portion 110. The second shell 200 further comprises a second positioning portion 230. The second positioning portion 230 is located on a side of the second supporting portion 210 away from the first mounting portion 110. The first positioning portion 130 and the second positioning portion 230 abut each other, and the first shell 100 rotates relative to the second shell 200 around the first positioning portion 130 to a side of the first shell 100 closer to the second shell 200, and the first shell 100 and the second shell 200 are covered.

[0064] Specifically, in the process of assembling the shell assembly, the first positioning portion 130 can be abutted to the second positioning portion 230, so as to pre-align the first shell 100 and the second shell 200 in the second direction through the first positioning portion 130 and the second positioning portion 230, so as to ensure that the first supporting portion 120 can be supported at a preset position of the circuit board 300. In addition, in the process of assembling, the first shell 100 and the second shell 200 can be rotated around the abutting position of the first positioning portion 130 and the second positioning portion 230, so that the first supporting portion 120 can abut to the first side of the circuit board 300 and push the circuit board 300 to rotate around the second supporting portion 210. Therefore, in the above embodiment, the abutment of the first positioning portion 130 to the second positioning portion 230 can provide support during the covering of the first shell 100 and the second shell 200, and improve the stability of the relative rotation of the first shell 100 and the second shell 200.

[0065] In some further optional embodiments, as shown in Figures 12 to 14 , the inner wall of one of the first positioning portion 130 and the second positioning portion 230 is provided with a positioning buckle 131, and the inner wall of the other is provided with a buckle groove 231. Referring to Figure 13 , the positioning buckle 131 is buckled in the buckle groove 231 when the first positioning portion 130 and the second positioning portion 230 abut each other.

[0066] Referring to Figure 14 , the positioning buckle 131 is buckled in the buckle groove 231, so that the first shell 100 and the second shell 200 can use the positioning buckle 131 and the buckle groove 231 to provide a support point for the rotation of the first shell 100 relative to the second shell 200 during the covering of the first shell 100 and the second shell 200. In this way, during the buckling of the first shell 100 and the second shell 200, only the end of the first shell 100 and the second shell 200 away from the first positioning portion 130 and the second positioning portion 230 needs to be pressed together, thereby facilitating the assembly of the shell assembly.

[0067] According to some optional embodiments, the shell assembly provided by the present application can be applied to an electronic device to provide a mounting base for a circuit board and other components in the electronic device through the shell assembly. In addition, the shape of the shell required by different electronic devices is different. Therefore, the present application does not limit the specific shape of the first shell 100 and the second shell 200.

[0068] For example, the shell assembly provided by the present application can be applied to, but is not limited to, an endoscope handle, a game handle, a support input system handle, etc.

[0069] In a second aspect, the present application provides an endoscope handle. For example, the endoscope handle includes a circuit board 300 and the shell assembly provided by the present application. The circuit board 300 has a first side and a second side opposite to each other. The first side of the circuit board 300 is abutted against the first mounting portion 110 and the first supporting portion 120, and at least part of the circuit board 300 is located in the first mounting groove 111, and the second side of the circuit board 300 is abutted against the second supporting portion 210.

[0070] The endoscope handle has the same technical features and can achieve the same technical effects as the shell assembly provided by the present application, and will not be described here.

[0071] In some optional embodiments, the circuit board 300 includes a first section 310 and a second section 320 connected to the first section 310. The second side of the first section 310 protrudes from the second side of the second section 320. One end of the first section 310 adjacent to the second section 320 and / or one end of the second section 320 adjacent to the first section 310 is abutted against the second supporting portion 210. In this embodiment, the second side of the first section 310 protrudes from the second side of the second section 320, which can provide a space for the circuit board 300 to deflect relative to the first shell 100.

[0072] In some optional embodiments, one end of the first section 310 away from the second section 320 and one end of the first section 310 close to the second section 320 can be abutted and limited by the first mounting portion 110 and the second supporting portion 210 respectively, thereby being beneficial to improve the reliability of the assembly of the circuit board 300 and the shell assembly.

[0073] In a third aspect, the present application provides an assembly method of an endoscope handle. The assembly method of the endoscope handle can be used to assemble the endoscope handle provided by the present application.

[0074] As shown in Figure 15 the assembly method of the endoscope handle includes the following steps:

[0075] Step 100, assembling the circuit board 300 to the second shell 200, and supporting the circuit board 300 on the second supporting portion 210.

[0076] Step 300, aligning the first shell 100 on the side of the first support part 120 away from the first mounting part 110 with the second shell 200;

[0077] Step 500, rotating the first shell 100 towards the side close to the second shell 200 with the first shell 100 and the second shell 200 as the center, until the circuit board 300 rotates around the first support part 120;

[0078] Step 700, aligning the first side of the circuit board 300 with the first mounting slot 111;

[0079] Step 900, rotating the first shell 100 towards the side close to the second shell 200 with the first shell 100 and the second shell 200 as the center, until the first shell 100 and the second shell 200 are closed.

[0080] In the process of assembling the handle of the endoscope by the above method, the first shell 100 is aligned and abuts with the second shell 200 on the side of the first support part 120 away from the first mounting part 110, so that the first shell 100 and the second shell 200 can support each other during closing, which is beneficial to control the relative attitude between the first shell 100 and the second shell 200, align the first shell 100 with the second shell 200, and align the circuit board 300 pre-installed on the second shell 200 with the first mounting slot 111 of the first mounting part 110, thereby reducing the assembly difficulty of the handle of the endoscope.

[0081] In some optional embodiments, part of the second side of the circuit board 300 is embedded in the mounting slot provided on the second support part 210 and / or the second mounting part 220, so that the circuit board 300 is supported on the second support part 210. As some optional embodiments, the length of the part of the circuit board 300 embedded in the third mounting slot 211 on the second support part 210 in the extension direction of the third mounting slot 211 is less than the length of the third mounting slot 211 in the extension direction thereof. That is, the insertion depth of the circuit board 300 is less than the depth of the circuit board 300 inserted into the third mounting slot 211 after the first shell 100 and the second shell 200 are closed. This is beneficial to increase the height of the circuit board 300 protruding from the second shell 200, thereby reducing the alignment difficulty of the circuit board 300 with the first mounting slot 111 in the first shell 100.

[0082] In some optional embodiments, the first shell 100 has a first positioning portion 130 on the side of the first support portion 120 away from the first mounting portion 110. In the case where the first shell 100 and the second shell 200 are closed, the portion of the second shell 200 that abuts against the first positioning portion 130 is a second positioning portion 230. The side of the first shell 100 on the first support portion 120 away from the first mounting portion 110 is positioned to abut against the second shell 200, i.e., the first positioning portion 130 is aligned with the second positioning portion 230 and abuts against the second positioning portion 230. In this way, the first shell 100 and the second shell 200 can support each other through the first positioning portion 130 and the second positioning portion 230.

[0083] In a fourth aspect, the present application provides an endoscope. The endoscope comprises the endoscope handle as described in the present application.

[0084] The endoscope of the embodiments of the present application can be a bronchoscope, a nephroscopy, an esophagoscope, a gastroscope, a colonoscope, an otoscope, a nasoscope, an oral cavity scope, a laryngoscope, a colposcope, a laparoscope, an arthroscope, etc. The embodiments of the present application do not specifically limit the type of the endoscope.
