Housing and camera equipment
[0001] This application claims priority to Chinese Patent Application No. 202422760018.3, filed on November 12, 2024, entitled “Casing and Camera Equipment”, the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of electronic technology, and in particular to housings and camera devices. Background Technology
[0003] The housing is a component of a camera device, used to house and protect the various electronic components of the camera device.
[0004] In related technologies, the housing mainly comprises an end cap and a housing. One end of the housing is closed, while the other end has an opening for electronic components to be installed inside. The end cap is installed at the opening of the housing and is detachably connected to the housing by multiple screws, thereby sealing the opening.
[0005] However, during the assembly of the end cap and housing, multiple screws need to be tightened sequentially, resulting in low installation efficiency. Summary of the Invention
[0006] This application provides a housing and a camera device to solve the problem of low housing assembly efficiency. The technical solution is as follows:
[0007] In a first aspect, a housing is provided, comprising a shell, an end cap, a locking structure, and a stop structure. The shell is the main body of the housing, and one end of the shell has an opening for inserting electronic devices into the shell for assembly. The end cap is located at the opening and is used to seal the opening. The end cap is movable relative to the shell, and the movable range of the end cap relative to the shell is between a locked position and an unlocked position. When the end cap is in the locked position, the locking structure locks the end cap and the shell together. Furthermore, when the end cap is in the locked position, the stop structure prevents the end cap from moving from the locked position to the unlocked position, thereby holding the end cap in the locked position and ensuring the mutual locking between the end cap and the shell.
[0008] The housing provided in this application embodiment has at least the following effects:
[0009] After the end cap is sealed to the opening of the housing, the end cap is moved from the unlocked position to the locked position, so that the end cap and the housing are mutually locked by the locking structure. Simultaneously, the stop structure ensures that the end cap remains in the locked position, thus guaranteeing continuous mutual locking between the end cap and the housing. The installation process of the end cap and housing does not involve the use of screws or other parts, thus effectively improving the assembly efficiency of the housing.
[0010] In one implementation of this application, the end cap moves in a first circumferential direction and a second circumferential direction, and the first circumferential direction and the second circumferential direction are two opposite directions. When the end cap moves from the unlocked position to the locked position, it moves relative to the housing along the first circumferential direction. When the end cap moves from the locked position to the unlocked position, it moves relative to the housing along the second circumferential direction. That is, by moving the end cap relative to the housing along either the first circumferential direction or the second circumferential direction, the movement of the end cap between the unlocked position and the locked position can be achieved.
[0011] In one implementation of this application, the end cap includes a cover body and a sleeve. A first end of the sleeve is connected to one side of the cover body. The sleeve is inserted into the opening to achieve mutual insertion between the end cap and the housing. The locking structure and the stop structure are located between the outer wall of the sleeve and the inner wall of the housing. The locking structure achieves mutual locking between the end cap and the housing, and the stop structure holds the end cap in the locked position, thereby maintaining the mutual locking between the end cap and the housing.
[0012] In one implementation of this application, the locking structure includes a groove and a slider. One of the groove and the slider is located on the outer wall of the sleeve, and the other is located on the inner wall of the housing. That is, if the groove is located on the outer wall of the sleeve, the slider is located on the inner wall of the housing; conversely, if the groove is located on the inner wall of the housing, the slider is located on the outer wall of the sleeve. The groove extends along the moving direction of the end cap, and its first end is a notch, which provides a channel for the slider to enter or exit the groove. If the groove is located on the outer wall of the sleeve, the notch is located at the second edge of the sleeve; if the groove is located on the inner wall of the housing, the notch is located at the opening edge of the housing. The slider is located within the groove and is movable relative to the groove. The slider can enter or exit the groove through the notch. By sliding the slider within the groove, it can be positioned within the groove, thereby achieving the locking structure's locking of the end cap and the housing.
[0013] In one implementation of this application, the slide groove includes an unlocking cavity and a locking cavity. The notch is located at the edge of the unlocking cavity, providing a channel for the slider to enter or exit the unlocking cavity. The locking cavity extends along the moving direction of the end cap, with a first end of the extending direction communicating with the unlocking cavity. In this way, the slider can move between the locking cavity and the unlocking cavity. When the end cap is in the unlocked position, the slider is located in the unlocking cavity, and the slider can enter or exit through the notch in the unlocking cavity. When the end cap is in the locked position, the slider is located within the locking cavity. By placing the slider within the slide groove, the locking structure locks the end cap and the housing.
[0014] In one implementation of this application, an inner wall of the unlocking cavity away from the locking cavity is a guide ramp. The extension direction of the guide ramp is inclined to the extension direction of the locking cavity. The first end of the guide ramp is located at the notch, and the second end of the guide ramp faces the locking cavity. The slider can slide in contact with the guide ramp. As the end cap moves relative to the housing, the slider also slides relative to the guide ramp, thereby allowing the slider to enter or exit the unlocking cavity from the notch along the guide ramp.
[0015] In one implementation of this application, the stop structure includes a first reverse tooth and a second reverse tooth. One of the first and second reverse teeth is located on the outer wall of the insert, and the other is located on the inner wall of the housing. That is, if the first reverse tooth is located on the outer wall of the insert, then the second reverse tooth is located on the inner wall of the housing; conversely, if the first reverse tooth is located on the inner wall of the housing, then the second reverse tooth is located on the outer wall of the insert. When the end cap is in the unlocked position, the inclined surfaces of the first and second reverse teeth face each other. Thus, when the end cap moves from the unlocked position to the locked position, the first and second reverse teeth are in contact with each other through their respective inclined surfaces. Through the sliding engagement between the two inclined surfaces, the first and second reverse teeth can interleave each other, thereby allowing the end cap to move from the unlocked position to the locked position. When the end cap is in the locked position, the stop surfaces of the first and second reverse teeth face each other. In this way, when the end cap moves from the locked position to the unlocked position, the first and second reverse teeth are in contact with each other through their respective stop surfaces. The abutment between the two stop surfaces prevents the first and second reverse teeth from moving from the locked position to the unlocked position, thus keeping the end cap in the locked position and ensuring continuous mutual locking between the end cap and the housing.
[0016] In one implementation of this application, the outer wall of the sleeve or the inner wall of the housing has a groove. The stop structure further includes a cantilever located within the groove. The length direction of the cantilever is consistent with the movement direction of the end cap, the fixed end of the cantilever is connected to the inner wall of the groove, and the first or second reverse tooth is located at the free end of the cantilever. Thus, the first or second reverse tooth can swing to a certain extent with the free end of the cantilever. On one hand, during the sliding engagement of the inclined surfaces of the first and second reverse teeth, under the elastic action of the cantilever, the first or second reverse tooth can adaptively swing, facilitating the interleaving of the first and second reverse teeth. After the first and second reverse teeth have interleaved, under the elastic action of the cantilever, the first or second reverse tooth can also self-reset, thereby achieving mutual stopping between the first and second reverse teeth. On the other hand, if the applied external force is large enough during the process of the stop surfaces of the first and second reverse teeth abutting each other, the cantilever can swing, causing the first and second reverse teeth to cross each other, thereby achieving unlocking.
[0017] In one implementation of this application, the stop structure further includes a reinforcing rib. The length direction of the reinforcing rib is consistent with the length direction of the cantilever, and the reinforcing rib is connected to the cantilever. The reinforcing rib effectively improves the structural strength of the cantilever, preventing breakage due to swinging and enhancing the reliability of the outer casing.
[0018] Secondly, a camera device is provided, comprising an electronic device and the housing described in the first aspect. The electronic device is located within the housing, which includes a casing, an end cap, a locking structure, and a stop structure. The casing is the main body of the casing, and one end of the casing has an opening for inserting electronic components into the casing for assembly. The end cap is located at the opening and is used to seal the opening. The end cap is movable relative to the casing, and the movable range of the end cap relative to the casing is between a locked position and an unlocked position. When the end cap is in the locked position, the locking structure locks the end cap and the casing. Furthermore, when the end cap is in the locked position, the stop structure prevents the end cap from moving from the locked position to the unlocked position, thereby holding the end cap in the locked position and ensuring mutual locking between the end cap and the casing.
[0019] The camera device provided in this application embodiment has at least the following effects:
[0020] After the end cap is sealed to the opening of the housing, the end cap is moved from the unlocked position to the locked position, so that the end cap and the housing are mutually locked by the locking structure. Simultaneously, the stop structure ensures that the end cap remains in the locked position, thus guaranteeing continuous mutual locking between the end cap and the housing. The installation process of the end cap and housing does not involve the use of screws or other parts, thus effectively improving the assembly efficiency of the housing. Attached Figure Description

[0028] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0029] The terminology used in the implementation section of this application is for the purpose of explaining the embodiments of this application only, and is not intended to limit this application.
[0030] A tube camera is a common type of video recording equipment. In related technologies, it mainly consists of a housing and electronic components, with the electronic components located inside the housing. The housing primarily comprises an end cap and a casing. One end of the casing is closed, while the other end has an opening for the electronic components to be housed within. The end cap is installed at the opening of the casing and is detachably connected to the casing by multiple screws, thus sealing the opening.
[0031] However, the assembly of the end cap and housing requires the sequential tightening of multiple screws, resulting in low installation efficiency and high labor costs. Furthermore, to ensure reliable assembly between the end cap and housing, the tightening torque of each screw is critical, making it difficult to meet the consistency requirements of the housing assembly. This increases hidden control costs and yield costs during mass production. Additionally, the installation of screws requires corresponding holes, which exposes the screws to the external environment, making them susceptible to corrosion.
[0032] To address the aforementioned technical problems, this application provides a camera device that includes a housing and electronic components, with the electronic components located within the housing.
[0033] Electronic devices are housed in a housing, which provides reliable protection for them.
[0034] Figure 1 is a schematic diagram of the housing structure. Referring to Figure 1, in this embodiment, the housing includes a housing 10, an end cap 20, a locking structure 30, and a stop structure 40. One end of the housing 10 has an opening 110. The end cap 20 is located at the opening 110 and is movable between a locked position and an unlocked position of the housing 10 (see Figure 2; the upper part of Figure 2 shows the end cap 20 in the locked position of the housing 10, and the lower part of Figure 2 shows the end cap 20 in the unlocked position of the housing 10). The locking structure 30 and the stop structure 40 are located between the housing 10 and the end cap 20. When the end cap 20 is in the locked position, the locking structure 30 locks the end cap 20 and the housing 10 together, and the stop structure 40 prevents the end cap 20 from moving from the locked position to the unlocked position.
[0035] In the above implementation, the housing 10 is the main body of the outer shell, and one end of the housing 10 has an opening 110 for placing electronic devices inside the housing 10 for easy assembly. An end cap 20 is located at the opening 110 and is used to seal the opening 110. The end cap 20 is movable relative to the housing 10, and its movable range is between the locked and unlocked positions of the housing 10. When the end cap 20 is in the locked position, the locking structure 30 can lock the end cap 20 and the housing 10. Furthermore, when the end cap 20 is in the locked position, the stop structure 40 can prevent the end cap 20 from moving from the locked position to the unlocked position, thereby keeping the end cap 20 in the locked position and ensuring the mutual locking between the end cap 20 and the housing 10.
[0036] During the assembly of the housing provided in this application embodiment, the end cap 20 is first placed over the opening 110 of the housing 10, at which point the end cap 20 is in the unlocked position. Then, the end cap 20 is moved from the unlocked position to the locked position, so that the end cap 20 and the housing 10 are mutually locked through the locking structure 30. Simultaneously, the stop structure 40 ensures that the end cap 20 remains in the locked position, thus guaranteeing continuous mutual locking between the end cap 20 and the housing 10.
[0037] During the installation of the end cap 20 and the housing 10, no screws or other parts are used, thus effectively improving the assembly efficiency of the housing.
[0038] As mentioned above, by moving the end cover 20 between the locked and unlocked positions, and in conjunction with the locking structure 30 and the stop structure 40, mutual locking between the end cover 20 and the housing 10 can be achieved. The following describes the mutual movement mechanism between the end cover 20 and the housing 10.
[0039] Referring to Figure 2, in this embodiment, the end cap 20 can move relative to the housing 10 along a first circumferential direction a and a second circumferential direction b, where the first circumferential direction a and the second circumferential direction b are two opposite directions. When the end cap 20 moves from the unlocked position to the locked position, the direction of movement of the end cap 20 is the first circumferential direction a, and when the end cap 20 moves from the locked position to the unlocked position, the direction of movement of the end cap 20 is the second circumferential direction b.
[0040] In the above implementation, both the first circumferential direction a and the second circumferential direction b are rotational directions. That is, the end cover 20 can rotate relative to the housing 10 in the first circumferential direction a and the second circumferential direction b. By rotating the end cover 20, it can move between the unlocked position and the locked position. It is worth noting that the first circumferential direction a and the second circumferential direction b are two opposite directions, referring to the relationship between the first circumferential direction a and the second circumferential direction b, such as the relationship between clockwise and counterclockwise directions.
[0041] As the end cap 20 moves from the unlocked position to the locked position, it moves relative to the housing 10 along a first circumferential direction a. As the end cap 20 moves from the locked position to the unlocked position, it moves relative to the housing 10 along a second circumferential direction b. In other words, by moving the end cap 20 relative to the housing 10 along either the first circumferential direction a or the second circumferential direction b, the end cap 20 can move between the unlocked and locked positions.
[0042] Figure 3 is a schematic diagram of the end cap 20. Referring to Figure 3, in this embodiment, the first end of the insert 220 is connected to one side of the cover 210. The insert 220 is inserted into the opening 110. The locking structure 30 and the stop structure 40 are located between the outer wall of the insert 220 and the inner wall of the housing 10 (see Figure 1).
[0043] In the above implementation, the insert 220 is inserted into the opening 110 to achieve mutual insertion between the end cap 20 and the housing 10. The locking structure 30 and the stop structure 40 are located between the outer wall of the insert 220 and the inner wall of the housing 10. The locking structure 30 achieves mutual locking between the end cap 20 and the housing 10, and the stop structure 40 holds the end cap 20 in the locked position, thereby maintaining mutual locking between the end cap 20 and the housing 10.
[0044] For example, the sleeve 220 is a cylindrical structure, and the axis of rotation of the end cap 20 and the axis of the sleeve 220 are collinear. Correspondingly, the inner wall profile of the housing 10 is cylindrical, and the axis of the inner wall profile of the housing 10 and the axis of the sleeve 220 are collinear.
[0045] For example, the side of the cover 210 that connects to the insert 220 abuts against the end of the housing 10 that has an opening 110. This design effectively improves the assembly seal between the end cover 20 and the housing 10.
[0046] For example, the cover 210 and the insert 220 are integral structural components. This design can improve the manufacturing efficiency of the end cover 20 on the one hand, and ensure the structural integrity and sealing performance of the end cover 20 itself on the other hand.
[0047] The locking structure 30 is described below.
[0048] Figure 4 is a schematic diagram of the structure of the housing 10. In conjunction with Figures 3 and 4, in this embodiment, the locking structure 30 includes a groove 310 and a slider 320.
[0049] The slide groove 310 extends along the moving direction of the end cap 20 relative to the housing 10. The first end of the slide groove 310 in the extending direction is a notch 311, which is located at the second end edge of the insert 220 or the edge of the opening 110 of the housing 10. The slider 320 is movably located within the slide groove 310. One of the slide groove 310 and the slider 320 is located on the outer wall of the insert 220, and the other of the slide groove 310 and the slider 320 is located on the inner wall of the housing 10.
[0050] In the above implementation, the groove 310 can be located on either the outer wall of the sleeve 220 or the inner wall of the housing 10. Similarly, the slider 320 can be located on either the outer wall of the sleeve 220 or the inner wall of the housing 10. In some examples, if the groove 310 is located on the outer wall of the sleeve 220 (see Figure 3), then the slider 320 is located on the inner wall of the housing 10 (see Figure 4). In other examples, if the groove 310 is located on the inner wall of the housing 10, then the slider 320 is located on the outer wall of the sleeve 220.
[0051] Correspondingly, the position of the notch 311 on the groove 310 varies depending on the location of the groove 310. For example, if the groove 310 is located on the outer wall of the sleeve 220, then the notch 311 is located at the second end edge of the sleeve 220; if the groove 310 is located on the inner wall of the housing 10, then the notch 311 is located at the edge of the opening 110 of the housing 10.
[0052] The notch 311 provides a channel for the slider 320 to enter or exit the slide groove 310. The slider 320 can enter or exit the slide groove 310 through the notch 311. By sliding the slider 320 in the slide groove 310, the slider 320 can be set in the slide groove 310, thereby realizing the locking structure 30 to lock the end cover 20 and the housing 10.
[0053] Referring again to Figure 3, in this embodiment, the slide 310 includes an unlocking cavity 312 and a locking cavity 313. The notch 311 is located at the edge of the unlocking cavity 312, and the locking cavity 313 extends along the moving direction of the end cover 20 relative to the housing 10. The first end of the extending direction of the locking cavity 313 communicates with the unlocking cavity 312.
[0054] In the above implementation, the notch 311 is located at the edge of the unlocking cavity 312, providing a channel for the slider 320 to enter or exit the unlocking cavity 312. The locking cavity 313 extends along the direction of movement of the end cover 20 relative to the housing 10, and the first end of the extending direction of the locking cavity 313 communicates with the unlocking cavity 312. In this way, the slider 320 can move between the locking cavity 313 and the unlocking cavity 312.
[0055] When the end cap 20 is in the unlocked position, the slider 320 is located in the unlocking cavity 312. When the end cap 20 is in the locked position, the slider 320 is located in the locking cavity 313 and is close to the second end of the locking cavity 313.
[0056] In other words, when the slider 320 is located in the unlocking cavity 312, the slider 320 is in a free state. On the one hand, the slider 320 can disengage from the unlocking cavity 312 through the notch 311 as the end cover 20 moves, thereby unlocking the end cover 20 and the housing 10. On the other hand, the slider 320 can also enter the locking cavity from the unlocking cavity 312 as the end cover 20 rotates, thereby locking the end cover 20 and the housing 10 (see Figure 5, which is a schematic diagram of the locked state between the slider 320 and the groove 310).
[0057] It is worth noting that, since the notch 311 is located at the second end edge of the insert 220 or at the edge of the opening 110 of the housing 10, the slider 320 disengages from the unlocking cavity 312 through the notch 311 via axial movement between the end cap 20 and the housing 10. The slider 320 enters the locking cavity 313 from the unlocking cavity 312 via circumferential movement, i.e., mutual rotation, between the end cap 20 and the housing 10.
[0058] In order to facilitate the slider 320 to enter or leave the unlocking cavity 312 through the notch 311, in this embodiment, the inner wall of the unlocking cavity 312 away from the locking cavity 313 is a guide ramp 314. The extension direction of the guide ramp 314 is inclined to the extension direction of the locking cavity 313. The first end of the guide ramp 314 is located at the notch 311, and the second end of the guide ramp 314 faces the locking cavity 313.
[0059] In the above implementation, the slider 320 can slide in contact with the guide ramp 314. As the end cap 20 moves relative to the housing 10, the slider 320 also slides relative to the guide ramp 314, so that the slider 320 can enter or leave the unlocking cavity 312 from the notch 311 along the guide ramp 314.
[0060] During the process of the slider 320 entering the notch 311, the assembler applies a certain axial force to the end cover 20 while screwing it on, causing the end cover 20 to tend to move towards the housing 10. In this way, when the slider 320 contacts the guide ramp 314, as the end cover 20 rotates, the slider 320 can enter the notch 311 along the guide ramp 314.
[0061] During the process of disengaging the slider 320 from the notch 311, the assembler can screw on the end cap 20 without actively applying an axial force away from the housing 10, ensuring safe disassembly. As the end cap 20 is screwed on, the slider 320 can contact the guide ramp 314, and thus passively generate an axial force away from the housing 10, allowing the slider 320 to disengage from the notch 311 along the guide ramp 314.
[0062] For example, the side of the slider 320 facing the guide ramp 314 has a guide ramp that matches the guide ramp 314. This further improves the smoothness of the slider 320 entering or leaving the unlocking cavity 312.
[0063] The stop structure 40 is described below.
[0064] Referring again to Figures 3 and 4, in this embodiment, the stop structure 40 includes a first reverse tooth 410 and a second reverse tooth 420. One of the first reverse tooth 410 and the second reverse tooth 420 is located on the outer wall of the insert 220, and the other of the first reverse tooth 410 and the second reverse tooth 420 is located on the inner wall of the housing 10.
[0065] In the above implementation, the first reverse tooth 410 can be located on either the outer wall of the sleeve 220 or the inner wall of the housing 10. Similarly, the second reverse tooth 420 can be located on either the outer wall of the sleeve 220 or the inner wall of the housing 10. In some examples, if the first reverse tooth 410 is located on the outer wall of the sleeve 220 (see Figure 3), then the second reverse tooth 420 is located on the inner wall of the housing 10 (see Figure 4). In other examples, if the first reverse tooth 410 is located on the inner wall of the housing 10, then the second reverse tooth 420 is located on the outer wall of the sleeve 220.
[0066] When the end cap 20 is in the unlocked position, the inclined surfaces of the first reverse tooth 410 and the second reverse tooth 420 are opposite each other. When the end cap 20 is in the locked position, the stop surfaces of the first reverse tooth 410 and the second reverse tooth 420 are opposite each other.
[0067] In this way, when the end cap 20 moves from the unlocked position to the locked position, the first reverse tooth 410 and the second reverse tooth 420 are in contact with each other through their respective inclined surfaces. Through the sliding engagement between the two inclined surfaces, the first reverse tooth 410 and the second reverse tooth 420 can cross each other, thereby allowing the end cap 20 to move from the unlocked position to the locked position.
[0068] When the end cap 20 moves from the locked position to the unlocked position, the first reverse tooth 410 and the second reverse tooth 420 are in contact with each other through their respective stop surfaces (see Figure 6, which is a schematic diagram of the locked state between the first reverse tooth 410 and the second reverse tooth 420). Through the abutment between the two stop surfaces, the first reverse tooth 410 and the second reverse tooth 420 abut against each other, thereby preventing the end cap 20 from moving from the locked position to the unlocked position, so that the end cap 20 can remain in the locked position, that is, ensuring the continuous mutual locking between the end cap 20 and the housing 10.
[0069] For example, the first inverted tooth 410 and the second inverted tooth 420 are triangular prism structural members. The first of the three sides of the triangular prism is used to connect the housing 10 or the end cap 20. The second of the three sides of the triangular prism is a bevel, and the third of the three sides of the triangular prism is a stop surface.
[0070] Referring again to Figure 3, in this embodiment, the outer wall of the sleeve 220 or the inner wall of the housing 10 has a groove 230, and the stop structure 40 also includes a cantilever 430. The length direction of the cantilever 430 is consistent with the movement direction of the end cap 20 relative to the housing 10. The cantilever 430 is located in the groove 230, and the fixed end of the cantilever 430 is connected to the inner wall of the groove 230. The first reverse tooth 410 or the second reverse tooth 420 is located at the free end of the cantilever 430.
[0071] In the above implementation, the groove 230 provides space for the swing of the cantilever 430. The first reverse tooth 410 or the second reverse tooth 420 is located at the free end of the cantilever 430. For example, when the groove 230 is located on the outer wall of the sleeve 220, if the first reverse tooth 410 is located on the outer wall of the sleeve 220, then the first reverse tooth 410 is located at the free end of the cantilever 430; if the second reverse tooth 420 is located on the outer wall of the sleeve 220, then the second reverse tooth 420 is located at the free end of the cantilever 430. When the groove 230 is located on the inner wall of the housing 10, if the first reverse tooth 410 is located on the inner wall of the housing 10, then the first reverse tooth 410 is located at the free end of the cantilever 430; if the second reverse tooth 420 is located on the inner wall of the housing 10, then the second reverse tooth 420 is located at the free end of the cantilever 430.
[0072] The following explanation uses the example of the first reverse tooth 410 located at the free end of the cantilever 430. The first reverse tooth 410 can swing to a certain extent with the free end of the cantilever 430. On the one hand, during the sliding engagement of the inclined surfaces of the first reverse tooth 410 and the second reverse tooth 420, under the elastic action of the cantilever 430, the first reverse tooth 410 can swing adaptively, thus facilitating the interleaving of the first reverse tooth 410 and the second reverse tooth 420. After the first reverse tooth 410 and the second reverse tooth 420 have interleaved, under the elastic action of the cantilever 430, the first reverse tooth 410 can also reset itself, thereby achieving mutual stopping between the first reverse tooth 410 and the second reverse tooth 420.
[0073] On the other hand, if the applied external force is large enough during the process of the stop surface of the first reverse tooth 410 and the stop surface of the second reverse tooth 420 abutting each other, the cantilever 430 can also swing, causing the first reverse tooth 410 and the second reverse tooth 420 to cross each other, thereby achieving unlocking.
[0074] It is worth noting that the sufficiently large external force mentioned above refers to the large torque applied by the assembler when intentionally removing the end cover 20. This torque is not usually applied to the end cover 20 during normal use of the camera equipment. In this way, it can be ensured that the end cover 20 will not loosen unnecessarily, while also ensuring that the end cover 20 can be removed when needed.
[0075] For example, the outer contour of the end cap 20 is square. This design allows the assembler to apply a sufficiently large external force to the end cap 20 using tools such as a wrench with a corresponding square inner contour when it is necessary to disassemble the end cap 20, thereby overcoming the mutual stop between the first reverse tooth 410 and the second reverse tooth 420.
[0076] Referring again to Figure 3, in this embodiment, the stop structure 40 further includes a reinforcing rib 440. The length direction of the reinforcing rib 440 is consistent with the length direction of the cantilever 430, and the reinforcing rib 440 is connected to the cantilever 430.
[0077] In the above implementation, the reinforcing rib 440 can effectively improve the structural strength of the cantilever 430, prevent the cantilever 430 from breaking due to swinging, and improve the reliability of the shell.
[0078] For example, one end of the reinforcing rib 440 near the fixed end of the cantilever 430 is connected to the inner wall of the groove 230 together with the fixed end of the cantilever 430. This design can strengthen the connection between the fixed end of the cantilever 430 and the inner wall of the groove 230 through the reinforcing rib 440.
[0079] For example, one end of the reinforcing rib 440 near the free end of the cantilever 430 is spaced apart from the first inverted tooth 410 or the second inverted tooth 420. This design effectively avoids interference caused by the reinforcing rib 440 crossing over the first inverted tooth 410 and the second inverted tooth 420.
[0080] In this embodiment, the housing also includes a sealing ring 50.
[0081] In some examples, the sealing ring 50 is sandwiched between the outer wall of the insert 220 and the inner wall of the housing 10. In other examples, the sealing ring 50 is sandwiched between the side of the cover 210 facing the housing 10 and the side of the housing 10 facing the cover 210.
[0082] In the above implementation, the sealing ring 50 can effectively improve the sealing performance between the end cap 20 and the housing 10.
[0083] In this embodiment, one of the housing 10 and the end cap 20 has a sealing groove 240, and the sealing ring 50 is located in the sealing groove 240.
[0084] In the above implementation, the sealing groove 240 is used to accommodate the sealing ring 50 to ensure the sealing performance of the sealing ring 50.
[0085] In this embodiment, the sealing groove 240 is located on the outer wall of the insert 220, and the sealing groove 240 and the insert 220 are arranged coaxially. In this case, the sealing ring 50 is located inside the sealing groove 240, so as to be sandwiched between the outer wall of the insert 220 and the inner wall of the housing 10.
[0086] The assembly process of the outer shell provided in the embodiments of this application is briefly described below:
[0087] (1) Insert the sealing ring 50 into the sealing groove 240.
[0088] (2) Insert the end cap 20 into the opening 110 of the housing 10 along the axial direction, so that the end cap 20 is in the unlocked position of the housing 10. At this time, the slider 320 enters the unlocking cavity 312 through the notch 311.
[0089] (3) Twist the end cap 20 along the first circumferential direction a, so that the slider 320 moves along the guide ramp 314 toward the locking cavity 313. During the movement of the end cap 20 along the first circumferential direction a, the slider 320 moves to the second end near the locking cavity 313, and the first reverse tooth 410 and the second reverse tooth 420 cross each other. The second reverse tooth 420 falls into the gap between the first reverse tooth 410 and the reinforcing rib 440, so that the stop surface of the first reverse tooth 410 and the stop surface of the second reverse tooth 420 are opposite each other. At this time, the end cap 20 is in the locked position of the housing 10, and the end cap 20 and the housing 10 are locked together, completing the assembly of the outer shell.
[0090] The disassembly process of the outer casing is the reverse of the assembly process, and will not be described in detail here.
