[0043] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0044] An embodiment of the present application provides a camera to solve the problem that the front cover of the existing camera is connected to the shell by screws, which makes the front cover thicker and thus causes the camera to be heavy and unsightly. The following will be explained with reference to the accompanying drawings.

[0045] The camera provided in this embodiment of the application is shown in FIG. Figure 1 and Figure 5 , Figure 1 A schematic diagram of the assembly of a camera provided in an embodiment of the present application (the lens is not shown), Figure 5 This is an exploded view of a camera provided in an embodiment of the present application, and the camera comprises a housing 1, a lens assembly 2, and a cover assembly 3. A mounting port is provided at one end of the housing 1, and a mounting space is provided inside the housing 1, and the mounting space is connected to the mounting port; the lens assembly 2 is detachably mounted at one end of the mounting space near the mounting port, and a mounting groove is formed between the lens assembly 2 and the housing 1; the cover assembly 3 is covered in the mounting groove, and has an interference fit with the lens assembly 2 and the housing 1.

[0046] The camera provided in this embodiment of the application is shown in FIG. Figure 2 , Figure 2 The schematic diagram of the assembly of the lens assembly and the shell of the camera provided in the embodiment of the present application, wherein a mounting groove is formed between the lens assembly 2 and the shell 1, and the effect of covering the mounting groove is achieved by interference fitting the cover assembly 3 into the mounting groove. At the same time, the connection effect between the lens assembly 2 and the shell 1 is tightened, and there is no structural damage to the lens assembly 2 or the shell 1, which affects the material strength of the lens assembly 2 or the shell 1, thereby reducing the compression and shear resistance of the lens assembly 2 or the shell 1; moreover, the interference fitting method has no requirements on the material strength of the lens assembly 2 or the shell 1 itself, so there is no need to thicken the cover or the shell 1 based on the existing cover thickness or the shell 1 thickness, so as to avoid increasing the overall quality of the camera; finally, the interference fitting method is simple to operate, and does not require the use of other tools. It can be directly assembled by manual press, saving time and effort.

[0047] Optionally, the cover assembly 3 includes a cover body 31 and a fixing member 32, the cover body 31 is covered in the installation groove, the cover body 31 includes a first side wall 311 facing the lens assembly 2, and a second side wall 312 facing the housing 1; the fixing member 32 includes a first fixing portion 321, the first fixing portion 321 is interference-fitted between the first side wall 311 and the lens assembly 2, and / or, interference-fitted between the second side wall 312 and the housing 1. The first fixing portion 321 is made of elastic material.

[0048] In some examples, the fixing member 32 includes a first fixing portion 321, and the first fixing portion 321 is interference-fitted between the first side wall 311 and the lens assembly 2; in other examples, the fixing member 32 includes a first fixing portion 321, and the first fixing portion 321 is interference-fitted between the second side wall 312 and the shell 1; in other examples, the fixing member 32 includes two first fixing portions 321, one first fixing portion 321 is interference-fitted between the second side wall 312 and the shell 1, and the other first fixing portion 321 is interference-fitted between the first side wall 311 and the lens assembly 2.

[0049] By interference fitting the first fixing portion 321 between the cover body 31 and the lens assembly 2 or the shell 1, and utilizing the elasticity of the first fixing portion 321, the cover body 31, the lens assembly 2 and the shell 1 are pressed tightly to achieve the connection and fixation of the cover body 31, the lens assembly 2 and the shell 1. At the same time, the connection structure is simple, and there is no need to drill holes on the shell 1, the cover body 31 or the lens assembly 2, thereby destroying the material strength of the corresponding components.

[0050] The material of the fixing member 32 is not further limited here. In some examples, the fixing member 32 can be made of a woven mesh with adhesive backing.

[0051] Optionally, the fixing member 32 includes a plurality of fixing members 32, each of which has a different color, and the cover body 31 is provided with a fixing member 32 of one of the colors. The color of the fixing member 32 is not further limited here, and can be, for example, gray, yellow, red, etc. By changing the color of the fixing member 32, the overall aesthetics of the device is improved.

[0052] Optionally, the fixing member 32 may be glued to the cover body 31. For example, the glue connection may be performed by using a heat-sensitive glue.

[0053] Optionally, the first fixing portion 321 is covered on the first side wall 311 and / or the second side wall 312. In some examples, the first fixing portion 321 is covered on the first side wall 311; in other examples, the first fixing portion 321 is covered on the second side wall 312; in other examples, the first fixing portion 321 is covered on both the first side wall 311 and the second side wall 312.

[0054] That is, the first fixing portion 321 completely fills the assembly gap between the cover body 31 and the lens assembly 2 and the shell 1. When the first fixing portion 321 is subjected to force and elastically deforms, the gap between the cover body 31, the lens assembly 2 and the shell 1 is further squeezed, thereby improving the airtightness between the cover body 31 and the lens assembly 2 and the shell 1, and preventing water seepage and the like from occurring at the connection between the cover body 31 and the lens assembly 2 and the shell 1.

[0055] Preferably, the first fixing portion 321 covers the first side wall 311 and the second side wall 312 at the same time, thereby improving the airtightness between the cover body 31 and the lens assembly 2 and the shell 1, and at the same time, providing a buffer space between the cover body 31 and the lens assembly 2 and the shell 1 to prevent scratches and damage between the cover body 31 and the lens assembly 2 and the shell 1 when the cover body 31 is installed in the installation groove.

[0056] Optionally, see Figure 3 to Figure 4 , Figure 3 for Figure 1 The main cross-sectional view of Figure 4 for Figure 3 In the partial enlarged view at point A, the lens assembly 2 includes a lens ring 21, and the lens ring 21 includes a ring body 211 and a connecting plate 212, and the connecting plate 212 is connected between the ring body 211 and the shell 1; the cover body assembly 3 is installed on the side of the connecting plate 212 facing the installation port, and an installation cavity 4 is formed between the connecting plate 212 and the cover body assembly 3; the camera also includes an audio part, the audio part is installed in the installation cavity 4, the audio part is provided with an audio port 2211, and the cover body assembly 3 is provided with an audio channel 314, and the audio channel 314 is connected to the audio port 2211.

[0057] Specifically, the connecting plate 212 and the ring body 211 are in a boss shape, the ring body 211 protrudes from the connecting plate 212 to one side of the installation port, and the connecting plate 212 and the ring body 211 are integrally formed, wherein the lens ring 21 can be made of plastic. The audio port 2211 of the audio part is used to receive or play audio.

[0058] By setting an audio channel 314 connected to the audio port 2211 on the cover assembly 3, the sound reception or broadcasting effect of the audio unit set inside the cover assembly 3 is guaranteed, and the poor sound reception or broadcasting effect of the audio unit due to the shielding of the cover assembly 3 is prevented, which affects the sound effect of the audio unit. At the same time, the audio unit is set in the cover assembly 3, and the cover assembly 3 provides a shielding protection effect for the audio unit to prevent the audio unit from being damaged by external impact. At the same time, due to the shielding of the cover assembly 3, the overall aesthetics of the camera is also improved, making the camera appearance simple and neat.

[0059] Optionally, see Fig. 9 , Fig. 9 This is an exploded view of the audio module and the sealing ring of the camera provided in the embodiment of the present application. The camera provided in the embodiment of the present application also includes a sealing ring 5, which is arranged between the audio part and the cover body assembly 3, and the through hole of the sealing ring 5 connects the audio channel 314 and the audio port 2211.

[0060] Since the sealing ring 5 is elastic, the tightness of the connection between the sealing ring 5 and the audio part and the cover assembly 3 is higher than the tightness of the direct connection between the audio part and the cover assembly 3. That is, the sealing ring 5 further limits the connection between the audio port 2211 and the audio channel 314, so that the audio between the audio port 2211 and the audio channel 314 only passes through the through hole of the sealing ring 5, thereby preventing the audio between the audio port and the audio channel 314 from diffusing into the entire installation cavity 4, thereby reducing the reception or broadcasting effect of the audio part.

[0061] Optionally, the sealing ring 5 is provided with a protruding extrusion portion 51, which is arranged around the opening of the through hole of the sealing ring 5, and is used to deform when under pressure to strengthen the connection between the cover assembly 3 and the audio part; wherein the extrusion portion 51 is located on the side of the sealing ring 5 facing the audio part, and / or, on the side of the sealing ring 5 facing the cover assembly 3. It should be noted that the extrusion portion 51 and the sealing ring 5 are integrally formed and both have elasticity.

[0062] In some examples, the extrusion portion 51 is located on the side of the sealing ring 5 facing the audio portion; in other examples, the extrusion portion 51 is located on the side of the sealing ring 5 facing the cover assembly 3; in other examples, the extrusion portion 51 includes a pair, one extrusion portion 51 is located on the side of the sealing ring 5 facing the cover assembly 3, and the other extrusion portion 51 is located on the side of the sealing ring 5 facing the audio portion.

[0063] By providing an extrusion portion 51 on the sealing ring 5, the connection area between the sealing ring 5 and the audio part or the cover assembly 3 is reduced. When the pressure applied to the cover assembly 3 is constant, the smaller the area of ​​the extrusion portion 51 is, the greater the pressure applied to the extrusion portion 51 is, and the greater the deformation of the extrusion portion 51 is. Therefore, the tighter the connection between the sealing ring 5 and the audio part and the cover assembly 3 is, the better the airtightness of the audio part is, and the better the sound reception or broadcasting effect is.

[0064] Optionally, the cover body 31 further includes a third side wall 313 connecting the first side wall 311 and the second side wall 312; see Figure 8 , Figure 8 The structural diagram of the fixing member of the camera provided in the embodiment of the present application, the fixing member 32 also includes a second fixing portion 322, the second fixing portion 322 is connected to the first fixing portion 321, and is covered on the third side wall 313, and the second fixing portion 322 is made of a breathable material. Among them, the second fixing portion 322 can be connected with the first fixing portion 321 to form an integral body, and the second fixing portion 322 and the first fixing portion 321 can both be made of a woven mesh adhesive cloth material, which is elastic and breathable.

[0065] Since the second fixing part 322 is made of breathable material, the second fixing part 322 not only protects the cover body 31 and prevents the cover body 31 from being damaged by external impact, but also ensures the smooth flow of the audio channel 314 without affecting the reception or broadcasting effect of the audio part. At the same time, the second fixing part 322 is connected to the first fixing part 321 to wrap the cover body 31 on the outside of the cover body 31, thereby ensuring the air tightness and waterproofness of the connection between the cover body 31 and the lens assembly 2 and the shell 1, and effectively preventing the camera from being damaged and water seeping.

[0066] Preferably, the fixing member 32 includes a pair of first fixing portions 321 and a second fixing portion 322, wherein the pair of first fixing portions 321 are respectively covered on the first side wall 311 and the second side wall 312 of the cover body 31, and the second fixing portion 322 is covered on the third side wall 313 of the cover body 31. The fixing member 32 is used to protect the cover body 31 at the periphery of the cover body 31, and at the same time, the interference fit between the cover body 31 and the lens assembly 2 and the shell 1 is ensured.

[0067] Optionally, the shell 1 includes an inner wall surrounding the installation space, and a limiting portion 11 is protruded from the inner wall. The limiting portion 11 is located on a side of the cover assembly 3 away from the installation opening and is in limiting contact with the cover assembly 3.

[0068] By setting a limit portion 11 in the installation space, the cover body assembly 3 is limited and resisted to prevent the cover body 31 from crushing the lens assembly 2 due to excessive force during assembly. When the cover body 31 moves beyond the set range, the limit portion 11 abuts against the cover body 31 in the assembly direction of the cover body 31 to prevent damage to the lens assembly 2 or the cover body 31.

[0069] Optionally, the limiting portion 11 is annular and extends along the circumference of the inner wall, that is, the limiting portion 11 is annular and limits the cover body 31 around the cover body 31 to ensure safe assembly of the cover body 31.

[0070] Optionally, the limiting portion 11 extends from one end of the shell 1 away from the installation port to the end close to the cover body 31 away from the installation port, and the limiting effect of the limiting portion 11 on the cover body 31 is increased by extending the length of the limiting portion 11. At this time, the shell 1 has two shell wall thicknesses along the length and short directions, which is easy to process.

[0071] Optionally, see Figure 6 , Figure 7 and Fig.10 , Figure 6 This is a bottom view of the cover body of the camera provided in an embodiment of the present application, Figure 7 A top view of the cover body of the camera provided in an embodiment of the present application, Fig.10 A schematic diagram of the lens ring of the camera provided in an embodiment of the present application, wherein a positioning column 23 and / or a positioning hole 33 is provided on the side of the lens assembly 2 facing the cover assembly 3, and a positioning hole 33 and / or a positioning column 23 is correspondingly provided on the side of the cover assembly 3 facing the lens assembly 2, and the positioning hole 33 matches the positioning column 23.

[0072] In some examples, the side of the lens assembly 2 facing the cover assembly 3 is provided with a positioning post 23, and the side of the cover assembly 3 facing the lens assembly 2 is correspondingly provided with a positioning hole 33; in other examples, the side of the lens assembly 2 facing the cover assembly 3 is provided with a positioning hole 33, and the side of the cover assembly 3 facing the lens assembly 2 is correspondingly provided with a positioning post 23; in other examples, the side of the lens assembly 2 facing the cover assembly 3 is provided with a positioning hole 33 and a positioning post 23 at intervals, and the side of the cover assembly 3 facing the lens assembly 2 is correspondingly provided with a positioning post 23 and a positioning hole 33 at intervals.
