Abstract

This application provides a camera, including a housing, a mounting base, a retaining ring, a lens mount, a lens, and an elastic element. The housing has a cavity, and the mounting base is fixed to the rear end of the housing to close the cavity. The retaining ring is connected to the mounting base and forms a receiving cavity with the mounting base. The retaining ring has a through hole communicating with the receiving cavity. The lens mount is located in the receiving cavity and has a receiving cavity, and the lens mount can move along the receiving cavity. The lens is received in the cavity and includes a first end and a second end opposite to each other. The first end is received in the receiving cavity, and the second end abuts against the front end of the housing. The through hole is for the lens to pass through. During assembly, the first end can be placed in the receiving cavity first, and then the housing and the mounting base can be fixed, which facilitates assembly. The elastic element is located in the receiving cavity and abuts against the lens mount and the mounting base. The elastic element provides an elastic resisting force so that the second end abuts against the front end of the housing, preventing the view of the lens from being affected; in addition, when the length tolerance of the housing is large, the elastic element can absorb the tolerance to adapt to the assembly.

[0036] Here, the technical solutions in the embodiments (or "embodiment modes") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description involves the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0037] If there are terms related to directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), then such terms are only used to explain the relative positional relationships and movement conditions between components in a specific posture (as shown in the accompanying drawings); if this specific posture changes, then the directional indication or positional relationship also changes accordingly. In addition, terms such as "first" and "second" involved in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0038] In some embodiment modes, the camera 100 of the present application can be used for monitoring high-temperature kilns, mainly for monitoring the inside of high-temperature kilns, and the present application does not limit the application scenarios of the camera 100.

[0039] Refer Figures 1 to 6 , the camera 100 of the present application includes a housing 1, a fixed seat 2, a pressure ring 3, a lens mount 4, a lens 5, and an elastic member 6.

[0040] The outer shell 1 has a cavity 11, and the fixing seat 2 is fixed to the rear end of the outer shell 1 to close the cavity 11. The pressure ring 3 is connected to the fixing seat 2 and forms a receiving cavity 31 with the fixing seat 2. The pressure ring 3 has a through hole 32 communicating with the receiving cavity 31. The lens mount 4 is located in the receiving cavity 31 and has a receiving cavity 41. The lens mount 4 can move along the receiving cavity 31. The lens 5 is received in the cavity 11 and includes a first end 51 and a second end 52 opposite to each other. The first end 51 is received in the receiving cavity 41, and the second end 52 abuts against the front end of the outer shell 1. The through hole 32 is used for the lens 5 to pass through. The elastic member 6 is located in the receiving cavity 31 and abuts against the lens mount 4 and the fixing seat 2. The elastic member 6 provides an elastic resisting force so that the second end 52 abuts against the front end of the outer shell 1.

[0041] The lens mount 4 allows for easy assembly of the camera 100 when the first end 51 of the lens 5 is placed in the receiving cavity 41 of the lens mount 4 before fixing the outer shell 1 and the fixing base 2. Simultaneously, the elastic member 6 applies a forward pushing force to the lens mount 4, ensuring that the second end 52 abuts against the outer shell 1, preventing the view of the lens 5 from being affected. Furthermore, when the length of the outer shell 1 is long and the length tolerance is large, the elastic member 6 can absorb the tolerance for adaptive assembly.

[0042] In some embodiments, the optical axis of the lens 5 is centered with the axis of the housing 1, thereby ensuring that the front field of view of the camera 100 is not affected by the processing error of the housing 1.

[0043] In some embodiments, the front end of the housing 1 has a protrusion 12, which is located within the cavity 11 and forms a receiving portion 121. A portion of the second end 52 is received within the receiving portion 121. The protrusion 12 supports and positions the lens 5 to increase its stability. The housing 1 has a transparent window 13 corresponding to the lens 5. In some embodiments, the lens 5 includes a first portion 53 and a second portion 54 connected to the first portion 53. The second portion 54 is elongated rod-shaped. The length of the first portion 53 is less than the length of the second portion 54, and its width is greater than the width of the second portion 54. The first end 51 is disposed in the first portion 53, and the second end 52 is disposed in the second portion 54.

[0044] In some embodiments, the cavity 11 includes a first cavity 111 and a second cavity 112 communicating with the first cavity 111. The length of the first cavity 111 is less than that of the second cavity 112, and its width is greater than that of the second cavity 112. The pressure ring 3 and the first part 53 are accommodated in the first cavity 111, and the second part 54 is accommodated in the second cavity 112.

[0045] In some embodiments, the housing 1 includes a third cavity 113 disposed around the second cavity 112. The housing 1 further includes a first air inlet 14 communicating with the cavity 11 and a second air inlet 15 communicating with the third cavity 113. The first air inlet 14 and the second air inlet 15 are for cold air to enter to cool the lens 5, ensuring that a relatively low temperature can be maintained in a high-temperature kiln to protect the lens 5 from being damaged by high temperature.

[0046] In some embodiments, the first air inlet 14 and the second air inlet 15 can be connected to an air pump.

[0047] In some embodiments, the housing 1 is cylindrical, including a thick circular tube and a thin circular tube connected to the thick circular tube. The fixing base 2 is fixed to the thick circular tube. The first cavity 111 is disposed in the thick circular tube, and the second cavity 112 is disposed in the thin circular tube. The lens holder 4 is located in the thick circular tube. The first air inlet 14 and the second air inlet 15 are both disposed in the thick circular tube. The second end 52 abuts against the top end of the thin circular tube, and the transparent window 13 is disposed on the thin circular tube.

[0048] In some embodiments, the housing 1 and the fixing base 2 can be fixed by means of screwing, welding, bonding, screw connection, bolt connection, snap connection, etc. The housing 1 and the fixing base 2 can be sealed by means of a sealing ring, sealant, etc.

[0049] In some embodiments, the pressure ring 3 and the fixing base 2 can be fixed by means of screwing, welding, bonding, screw connection, bolt connection, snap connection, etc.

[0050] See Figure 2 and Figure 7 In some embodiments, the camera further includes a camera module 7 and a window glass 8 located between the camera module 7 and the lens 5.

[0051] In some embodiments, the camera module 7 is fixed to the fixing base 2.

[0052] In some embodiments, the camera 100 is a high-temperature explosion-proof camera, the housing 1 is an explosion-proof housing, the lens 5 is a high-temperature lens, and the window glass 8 is explosion-proof glass.

[0053] In some embodiments, the housing 1 is made of a high-temperature-resistant metal material so that the camera 100 can withstand the high temperature inside the furnace.

[0054] Refer Figure 4 , the fixing base 2 includes a first window 211 communicating with the storage cavity 31 for the end of the movement mechanism 7 to pass through, the lens holder 4 includes a second window 42 communicating the accommodation cavity 41 with the storage cavity 31, the window glass 8 is located in the storage cavity 31, and along the length direction of the lens 5, the movement mechanism 7, the window glass 8, the second window 42 and at least part of the lens 5 are arranged in sequence.

[0055] The window glass 8 can be fixed to the fixing base 2. For example, it can be fixed by bonding or welding or by other fixing devices.

[0056] In some embodiments, a part of the lens 5 can also pass through the second window 42.

[0057] In some embodiments, the fixing base 2 includes a base 21 and a convex column 22 extending from the base 21, and the first window 211 is provided on the base 21. The base 21 is fixed to the housing 1. The compression ring 3 is fixed to the convex column 22. One end of the elastic member 6 abuts against the convex column 22.

[0058] In some embodiments, a slot hole 221 is provided on the convex column 22, and one end of the elastic member 6 is received in the slot hole 221 to increase the stability of the elastic member 6.

[0059] Refer Figures 4 to 6 , when assembling the camera 100, the first end 51 of the lens 5 can be first placed in the accommodation cavity 41 of the lens holder 4. During this process, the lens 5 abuts against the lens holder 4, and the lens holder 4 squeezes the elastic member 6 so that it is compressed in the direction towards the fixing base 2; then the housing 1 is fixed to the fixing base 2; after the thrust applied to the lens 5 disappears, the elastic force of the elastic member 6 abuts against the lens 5 to make it move towards the front end of the housing 1 to abut against the front end of the housing 1.

[0060] Refer Figure 8, the pressing ring 3 is detachably connected to the fixed seat 2, facilitating the maintenance of the elastic member 6 and the window glass 8. The camera 100 includes a third seal 10, which is located between the pressing ring 3 and the fixed seat 2 and is sealed through the third seal 10 to prevent dust, oil and gas, water vapor, etc. from entering the storage cavity 31 through the gap between the pressing ring 3 and the fixed seat 2, preventing the window glass 8 from being soiled or fogged, so as not to affect the clarity of the captured image.

[0061] Optionally, a receiving groove 212 is provided on the base 21, and a part of the third seal 10 is received in the receiving groove 212 to increase the stability of the third seal 10.

[0062] The third seal 10 can be made of silica gel, rubber, sealant, etc., or can also be a seal formed by welding.

[0063] Refer Figures 9 to 10 , the camera 100 includes a first seal 40 located between the lens 5 and the lens holder 4 to prevent dust, oil and gas, water vapor, etc. from entering the storage cavity 31 through the gap between the lens 5 and the lens holder 4, preventing the window glass 8 from being soiled or fogged, so as not to affect the clarity of the captured image.

[0064] The first seal 40 can be made of silica gel, rubber, sealant, etc., or can also be a seal formed by welding.

[0065] The lens holder 4 includes an annular first side wall 43 and a fixing portion 44 extending from the first side wall 43. The first side wall 43 encloses the storage cavity 41, and the fixing portion 44 encloses the second window 42. The first seal 40 is fixed to the fixing portion 44.

[0066] The first seal 40 forms a recessed groove 400, and the fixing portion 44 is received in the recessed groove 400, increasing the stability of the first seal 40 and further improving the sealing effect.

[0067] Refer Figures 11 to 12 , in another embodiment, along the width direction of the lens 5, the first seal 40 is located between the lens 5 and the lens holder 4. The first seal 40 is located between the lens 5 and the first side wall 43.

[0068] In some embodiments, the side wall 43 is provided with a receiving groove 430, and the first seal 40 is received in the receiving groove 430 to increase the stability of the first seal 40.

[0069] In another embodiment, the first seal 40 includes a first connecting portion 401, and a first lip 402 and a second lip 403 extending in the same direction from the first connecting portion 401. The first lip 402 is in sealing contact with the lens 5, and the second lip 403 is in sealing contact with the first side wall 43. A first opening 4041 of a first gap 404 between the first lip 402 and the second lip 403 faces the front end of the housing 1.

[0070] When the air pressure outside the storage cavity 31 is greater, referring to the pressure of the air pressure in the direction of the arrow shown, the closer the first lip 402 is in contact with the lens 5 and the closer the second lip 403 is in contact with the first side wall 43, the better the sealing effect of the first seal 40. Figure 12 When the air pressure inside the storage cavity 31 is greater than the air pressure outside it, the gas inside the storage cavity 31 can flow to the outside of the storage cavity 31 through the gap between the first lip 402 and the lens 5 or the gap between the second lip 403 and the first side wall 43, avoiding water vapor saturation inside the storage cavity 31 and preventing fogging on the window glass 8, so as not to affect the clarity of the captured image.

[0071] When the air pressure inside the storage cavity 31 is greater than the air pressure outside it, the gas inside the storage cavity 31 can flow to the outside of the storage cavity 31 through the gap between the first lip 402 and the lens 5 or the gap between the second lip 403 and the first side wall 43, avoiding water vapor saturation inside the storage cavity 31 and preventing fogging on the window glass 8, so as not to affect the clarity of the captured image.

[0072] In another embodiment, along the circumferential direction of the lens 5, the deformation amount of the first lip 402 is the same, so that the axis of the lens 5 is substantially coincident with the axis of the lens holder 4, so as not to affect the imaging effect due to too large axis deviation.

[0073] Referring to Figures 2 to 3 and Figures 13 to 16 , the camera 100 includes a second seal 47 located between the lens holder 4 and the press ring 3 to prevent dust, oil gas, water vapor, etc. from entering the storage cavity 31 through the gap between the lens holder 4 and the press ring 3, and to prevent fogging on the window glass 8, so as not to affect the clarity of the captured image.

[0074] The second seal 47 can be silicone, rubber, sealant, etc., or can also be a seal formed by welding.

[0075] In some embodiments, along the width direction of the lens 5, the second seal 47 is located between the lens holder 4 and the press ring 3.

[0076] In some embodiments, the second seal 47 includes a second connecting portion 471, and a third lip 472 and a fourth lip 474 extending in the same direction from the second connecting portion 471. The third lip 472 is in sealing contact with the pressure ring 3, and the fourth lip 474 is in sealing contact with the lens mount 4. The second opening 4751 of the second gap 475 between the third lip 472 and the fourth lip 474 faces the front end of the housing 1.

[0077] When the air pressure outside the storage cavity 31 is greater, referring to Figure 16 the pressure of the air pressure in the direction of the arrow shown, the third lip 472 and the pressure ring 3 and the fourth lip 474 and the lens mount 4 are in closer contact, and the sealing effect of the second seal 47 is better.

[0078] When the air pressure inside the storage cavity 31 is greater than the air pressure outside it, the gas in the storage cavity 31 can flow to the outside of the storage cavity 31 through the gap between the third lip 472 and the pressure ring 3 or the gap between the fourth lip 474 and the lens mount 4, avoiding water vapor saturation in the storage cavity 31 and preventing fogging on the window glass 8, so as not to affect the clarity of the captured image.

[0079] The lens mount 4 includes a protrusion 46 provided on the first side wall 43. The protrusion 46 encloses a groove portion 461. The second seal 47 is located in the groove portion 461, and the elastic member 6 is sleeved around the periphery of the first side wall 43. Referring to Figure 3 , the pressure ring 3 includes a second side wall 33 and a flange 34 extending from the second side wall 33. The flange 34 is used to resist against the protrusion 46 to prevent the lens mount 4 from detaching from the pressure ring 3, and the flange 34 encloses the through hole 32.

[0080] Optionally, the second side wall 33 is fixed to the convex column 22.

[0081] Referring to Figure 3 , Figure 5 and Figure 17 , the outer diameter D1 of the ring formed by the protrusion 46 is greater than the diameter D2 of the through hole 32 to prevent the lens mount 4 from passing through the through hole 32. The diameter D3 of the first end 51 of the lens 5 is less than the diameter D2 of the through hole 32 to ensure that the first end 51 can pass through the through hole 32. The outer diameter D4 of the elastic member 6 is less than the diameter D5 of the storage cavity 31 to ensure that the elastic member 6 can be squeezed and deformed and the lens mount 4 can move.

[0082] Referring to Figure 8, the pressing ring 3 includes a convex edge 331 extending from the second side wall 33, and the convex edge 331 is in sealing fit with the third seal 10. The convex edge 331 and the retaining edge 34 are respectively formed by extending from the second side wall 33 in opposite directions.

[0083] In another embodiment, along the circumferential direction of the pressing ring 3, the deformation amount of the third lip 472 is the same, so that the axis of the lens holder 4 is substantially coincident with the axis of the pressing ring 3, so as to avoid affecting the imaging effect due to too large axis deviation.

[0084] The settings of the first seal 40, the second seal 47 and the third seal 10 prevent dirt such as water vapor and dust entering the cavity 11 through the first air inlet 14 from entering the storage cavity 31 and contaminating the window glass 8, so as to avoid affecting the clarity of the captured image; at the same time, the settings of the first lip 402 and the second lip 403 of the first seal 40 or the third lip 472 and the fourth lip 474 of the second seal 47, when the air pressure inside the storage cavity 31 is greater than the air pressure outside it, the gas in the storage cavity 31 can flow to the outside of the storage cavity 31, avoiding water vapor saturation in the storage cavity 31 and preventing fogging on the window glass 8, so as not to affect the clarity of the captured image.

[0085] See Figure 18 , when the lens 5 needs to be replaced, first remove the housing 1 from the fixed seat 2, and then remove the lens 5 from the lens holder 4; after the lens 5 is taken out, the lens holder 4 is reset to Figure 3 its original state by the abutting force of the elastic member 6; when installing the lens 5, insert the first end 51 of the lens 5 into the receiving cavity 41 of the lens holder 4, and then fix the housing 1 and the fixed seat 2, which can achieve the quick disassembly and quick installation of the lens 5, with convenient installation and cost saving; and the setting of the elastic member 6 ensures that the front end of the lens 5 abuts against the front end of the housing 1, so as not to affect the window view of the lens; furthermore, the settings of the first seal 40 and the second seal 47 not only achieve a good sealing effect, avoiding dirt from affecting the clarity of the captured image, but also ensure that the axes of the lens 5, the lens holder 4 and the pressing ring 3 are collinear, preventing the imaging center of gravity of the lens 5 from being offset and ensuring reliable imaging.

[0086] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
