Description

Technical Field

[0001] The present application relates to the field of camera technology, and in particular to a spherical camera. Background Art

[0002] As dome cameras are increasingly used in various industries, their functions are becoming more and more diverse, and the types of dome cameras are also increasing, such as infrared dome cameras, thermal imaging dome cameras, binocular infrared dome cameras, laser dome cameras, etc.

[0003] Different types of dome cameras contain different components, and their installation locations are also different. Therefore, one related technique involves designing separate dome cameras for each type. However, this approach results in poor versatility and a lack of standardized structure. Furthermore, different molds must be designed for each type of dome camera, increasing production costs. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a spherical camera, which can reduce the cost of the spherical camera.

[0005] In a first aspect of the present application, a dome camera is provided, comprising a mounting bracket and a dome camera body connected to the mounting bracket. The dome camera body is rotatably connected to the mounting bracket, thereby facilitating rotation of the dome camera body around the mounting bracket to capture image information at different positions.

[0006] The spherical camera body comprises a main structure, an extension structure, and a connecting structure. The main structure includes a main housing and an imaging lens fixed within the main housing. The imaging lens can be the primary imaging lens for acquiring image information. The extension structure includes an extension housing. This extension housing can be a hollow housing, meaning it can be empty of any components. Alternatively, it can house auxiliary camera components, such as a fill light or an auxiliary lens. The auxiliary lens can be a thermal imaging lens or other imaging lens. The extension housing can be fixed to one end of the main housing via the connecting structure.

[0007] When manufacturing a dome camera, one possible method involves separately manufacturing the main structure, extension structure, and connecting structure, and then attaching the extension structure to the main structure via the connecting structure. In another possible method, the main structure and extension structure can be separately manufactured, and then secured to the main structure and extension structure via an auxiliary connecting material, thereby forming a connecting structure between the main structure and the extension structure. Since all types of dome cameras are equipped with a main imaging lens, which is fixed within the main housing, the installation position of the main imaging lens within the main housing is essentially the same. Therefore, the main structures of different types of dome cameras can be identical. In actual production, the main structures can be mass-produced and installed with extension structures of different structures to produce different types of dome cameras. This improves the versatility of the main structure, enabling better mass production of the main structure, and increases production efficiency, thereby reducing production costs. Furthermore, when manufacturing different types of dome cameras, the same main structure mold can be shared, thereby reducing mold costs and, consequently, the cost of the dome cameras.

[0008] Regarding the connection between the main housing and the extension housing, in one possible embodiment, portions of the main housing and portions of the extension housing are nested. In this case, the connection structure includes fasteners that penetrate and secure within the nested portion of the main housing and the extension housing to securely connect the extension housing to the main housing. This increases the connection area between the main housing and the extension housing, thereby improving the stability of the connection between the main housing and the extension housing.

[0009] In one example, a portion of the main shell extends into the extended shell, and a portion of the outer wall of the main shell that extends into the extended shell can contact the inner wall of the extended shell. The main shell includes a first shell body and a first built-in layer fixed in the first shell body. A first threaded hole is provided on the first built-in layer. The fastener includes a bolt, which passes through the extended shell, the first shell body and the first built-in layer and is connected to the first threaded hole. Specifically, a first through hole can be provided on the extended shell, and a second through hole can be provided on the first shell body. The first through hole, the second through hole and the first threaded hole are connected, and the bolt can pass through the first through hole, the second through hole and the first threaded hole in sequence and be tightened in the first threaded hole. This connection structure is relatively simple and firm.

[0010] Furthermore, the first inner layer extends inward from the first housing body, near one end of the extension housing, and covers a portion of the first housing body. In other words, the first inner layer is smaller in a first direction than the first housing body. The first direction can be the direction from the main structure toward the extension structure. This provides ample mounting space for fasteners. Furthermore, the second inner layer is not too large in the first direction, saving material and further reducing the cost of the dome camera.

[0011] In another example, part of the extended shell extends into the main shell, and the outer wall of the part of the extended shell that extends into the main shell can contact the inner wall of the main shell. The extended shell includes a second shell body and a second built-in layer fixed in the second shell body. A second threaded hole is provided on the second built-in layer. The fastener includes a bolt, which passes through the main shell, the second shell body and the second built-in layer and is connected with the second threaded hole. Specifically, a first through hole can be provided on the main shell, and a second through hole can be provided on the second shell body. The first through hole, the second through hole and the second threaded hole are connected, and the bolt can pass through the first through hole, the second through hole and the second threaded hole in sequence and be tightened in the second threaded hole. This connection structure is relatively simple and firm.

[0012] Furthermore, the second inner layer extends inward from the second housing body toward the end closest to the main housing, and covers a portion of the second housing body. In other words, the second inner layer's dimensions along the first direction are smaller than those of the second housing body. This provides ample mounting space for fasteners, while also minimizing the second inner layer's dimensions along the first direction, saving material and further reducing the cost of the dome camera.

[0013] Based on this, the connection structure also includes a seal, which is fixed to the nesting point of the main housing and the extension housing and covers the fastener. On the one hand, the seal not only covers the fastener, but also the gap between the fastener and the main housing or the extension housing, thereby improving the sealing performance. On the other hand, the fastener is not visible from the outside of the dome camera, thereby improving the aesthetic appearance of the dome camera.

[0014] Regarding the connection method between the main shell and the extended shell, in another possible embodiment, the connection structure includes a welding portion, and the main shell and the extended shell are arranged opposite to each other and fixedly connected by the welding portion. In the process of manufacturing a spherical camera, the main structure and the extended structure can be manufactured first. Both the main shell in the main structure and the extended shell in the extended structure can be made of metal materials. The main structure and the extended structure are then welded, for example, by laser welding, to form a welding portion between the main structure and the extended structure, that is, a welding portion is formed between the main shell and the extended shell. The welding manufacturing method can, on the one hand, avoid the formation of gaps between the main shell and the extended shell, thereby improving the sealing. On the other hand, it can also improve the stability of the connection between the main shell and the extended shell.

[0015] Regarding the connection method between the main shell and the extended shell, in another possible embodiment, the connection structure includes a sealant, and the main shell and the extended shell are arranged relative to each other and fixedly connected by the sealant. In the process of manufacturing a spherical camera, the main structure and the extended structure can be manufactured first. Both the main shell in the main structure and the extended shell in the extended structure can be made of plastic materials. The main structure and the extended structure are then welded, for example, by ultrasonic welding. Thereby, a sealant is formed between the main structure and the extended structure, that is, a sealant is formed between the main shell and the extended shell. The welding manufacturing method can, on the one hand, avoid the formation of gaps between the main shell and the extended shell, thereby improving the sealing. On the other hand, it can also improve the stability of the connection between the main shell and the extended shell.

[0016] In some embodiments of the present application, the main housing has a larger dimension along a first direction than the extended housing, where the first direction is the direction from the main structure toward the extended structure. The imaging lens secured within the main housing is a primary camera lens for acquiring image information. Other auxiliary camera components besides the primary imaging lens may be secured within the extended housing. Imaging lenses are typically large, so setting the main housing's dimension along the first direction to be larger than the extended housing's dimension along the first direction provides more space for the imaging lens.

[0017] The extended structure further includes a bracket and an auxiliary camera component, which may be, for example, a thermal imaging lens, a fill light, etc. The auxiliary camera component may be located in the extended housing and fixed to the bracket.

[0018] Regarding the fixed position of the bracket, in one possible embodiment, a portion of the bracket extends into and is fixed within the main housing, while the remaining portion of the bracket is suspended within the extended housing, and the auxiliary camera device is fixed to the portion of the bracket that extends into the extended housing. Because the main housing is typically larger in the first direction, when a portion of the bracket extends into and is fixed within the main housing, the main housing provides a larger connection area for that portion of the bracket, thereby more securely securing the bracket within the main housing.

[0019] In another possible embodiment, the bracket is located within the expansion housing, and the auxiliary camera component is secured within the expansion housing via the bracket. Thus, during the production of the expansion structure, the expansion housing, bracket, and auxiliary camera component can be separately manufactured. The auxiliary camera component is then mounted on the bracket, and the bracket with the auxiliary camera component mounted on the expansion housing, completing the production of the expansion structure. The main structure and the expansion structure are then secured together, completing the dome camera. Because the bracket is located within the expansion housing, securing the main structure and the expansion structure is more convenient.

[0020] In some embodiments of the present application, the main housing includes a first housing body and a first partition, with the first partition being fixed to one end of the first housing body facing the extension housing. This provides a higher overall structural strength for the main housing. Alternatively, the extension housing includes a second housing body and a second partition, with the second partition being fixed to one end of the second housing body facing the main housing. This provides a higher overall strength for the extension housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] As dome cameras are used more and more widely in various industries, their functions are becoming more and more diverse, and the types of dome cameras are also increasing. Figure 1a The infrared dome camera shown in Figure 1b The thermal imaging dome camera shown in Figure 1c The binocular infrared dome camera shown in Figure 1d The laser dome camera shown, etc.

[0045] like Figure 1a As shown, the dome camera 1 may include a mounting bracket 100 and a dome camera body 200, wherein the dome camera body 200 is connected to the mounting bracket 100. The dome camera body 200 may rotate around the mounting bracket 100 to obtain image information at different positions.

[0046] like Figure 1a As shown, the spherical camera body 200 in the infrared dome camera may include components such as a housing 201, an imaging lens 12, and two near-infrared fill lights 202. The imaging lens 12 and the two near-infrared fill lights 202 are both fixed in the housing 201, and the two near-infrared fill lights 202 are respectively located on both sides of the imaging lens 12.

[0047] like Figure 1b As shown, the spherical camera body 200 in a thermal imaging dome camera may include a housing 201, an imaging lens 12, a thermal imaging lens 203, and a near-infrared fill light 202. The imaging lens 12, thermal imaging lens 203, and near-infrared fill light 202 are all fixed within the housing 201. The imaging lens 12 and thermal imaging lens 203 are arranged side by side, with the near-infrared fill light 202 located below the imaging lens 12 and thermal imaging lens 203.

[0048] like Figure 1c As shown, the spherical camera body 200 in the binocular infrared dome camera may include a housing 201, an imaging lens 12, a thermal imaging lens 203, and two near-infrared fill lights 202. The imaging lens 12, the thermal imaging lens 203, and the near-infrared fill lights 202 are all fixed within the housing 201. The imaging lens 12 and the thermal imaging lens 203 are arranged along a first direction Z, and the two near-infrared fill lights 202 are located on either side of the imaging lens 12.

[0049] like Figure 1d As shown, the spherical camera body 200 in the laser spherical camera may include a housing 201, an imaging lens 12 and a laser fill light 204, wherein the imaging lens 12 and the laser fill light 204 are both fixed in the housing 201 and arranged side by side.

[0050] contrast Figure 1a 、 Figure 1b 、 Figure 1c and Figure 1d As can be seen, different types of dome cameras 1 contain different components, and their installation locations are also different. Therefore, in the first related art, separate designs are developed for each type of dome camera 1. However, this results in limited versatility and a lack of standardized structure. Furthermore, the need to design separate molds for each type of dome camera 1 increases the production cost of the dome camera 1.

[0051] In order to improve the versatility of each ball camera 1, in the second related technology, the ball camera body 200 includes all the above components, that is, the ball camera body 200 includes the imaging lens 12, the thermal imaging lens 203, the near-infrared fill light 202 and the laser fill light 204. In this way, the ball camera 1 can achieve Figure 1a 、 Figure 1b 、 Figure 1c and Figure 1d The functions of any of the dome cameras 1 shown are combined, thereby improving versatility.

[0052] However, since the dome camera 1 in the related art includes many components, the volume of the dome camera 1 will also be relatively large, which also leads to high costs.

[0053] Based on this, an embodiment of the present application provides a dome camera 1 , which can reduce the manufacturing cost of the dome camera 1 .

[0054] like Figure 2 As shown, the dome camera 1 includes a mounting bracket 100 and a dome camera body 200 connected to the mounting bracket 100. The dome camera body 200 is rotatably connected to the mounting bracket 100, thereby allowing the dome camera body 200 to rotate around the mounting bracket 100 to obtain image information at different positions.

[0055] like Figure 2 As shown, the spherical camera body 200 includes: a main body structure 10 , an expansion structure 20 and a connection structure 30 .

[0056] like Figure 2 As shown, the main structure 10 includes a main housing 11 and an imaging lens 12 fixed in the main housing 11. Specifically, the main structure 10 may also include a lens holder 14, and the imaging lens 12 may be fixed in the main housing 11 via the lens holder 14. The imaging lens 12 may be a main imaging lens 12 for acquiring image information.

[0057] like Figure 2 As shown, the expansion structure 20 may include an expansion housing 21 . The expansion housing 21 may be fixed to one end of the main housing 11 via a connection structure 30 .

[0058] When manufacturing a dome camera 1, one possible method involves separately manufacturing the main structure 10, the extension structure 20, and the connecting structure 30. The extension structure 20 is then mounted on the main structure 10 via the connecting structure 30. In another possible method, the main structure 10 and the extension structure 20 are separately manufactured, then secured to the main structure 10 and the extension structure 20 using an auxiliary connecting material, thereby forming the connecting structure 30 between the main structure 10 and the extension structure 20. Since all types of dome cameras 1 are equipped with a main imaging lens 12, which is fixed within the main housing 11, the installation position of the main imaging lens 12 within the main housing 11 is essentially the same. Therefore, the main structures 10 of different types of dome cameras 1 are identical. In actual production, the main structures 10 can be mass-produced and assembled with extension structures 20 of varying configurations to produce different types of dome cameras 1. This improves the versatility of the main structure 10, enabling better mass production of the main structure 10 and increasing production efficiency, thereby reducing production costs. Furthermore, when manufacturing different types of dome cameras 1 , the same set of molds for the main structure 10 can be shared, thereby reducing the mold cost and thus reducing the cost of the dome camera 1 .

[0059] Furthermore, in the second related art, only some of the components of the dome camera 1 are required for any given application, leaving the remaining components idle, thus wasting resources. In this embodiment, the auxiliary camera components 23 can be selected based on actual needs, and it is not necessary to install all types of auxiliary camera components 23 within the expansion housing 21, thus avoiding resource waste.

[0060] In this embodiment, if Figure 3 As shown, the extended housing 21 may be an empty housing, that is, no components may be installed in the extended housing 21. Figure 4 、 Figure 5 and Figure 6 As shown, the extended housing 21 may also be an extended housing 21 with a camera auxiliary device 23 installed therein. In one example, as shown in FIG. Figure 4 As shown, the camera auxiliary device 23 can be a fill light 231. Specifically, the fill light 231 can be a near-infrared fill light or a laser light. Figure 5 As shown, the camera auxiliary device 23 may be an auxiliary lens 232. The auxiliary lens may be, for example, a thermal imaging lens or other imaging lens. Figure 6 As shown, the camera auxiliary device 23 can be a speaker 233.

[0061] Furthermore, if Figure 2As shown, the main structure 10 may further include a first sensor board 13 and a main control board 15. The first sensor board 13 may be electrically connected to the imaging lens 12 to capture the image or video information captured by the imaging lens 12. The first sensor board 13 is electrically connected to the main control board 15, so that the first sensor board 13 can transmit the captured image or video information to the main control board 15. The main control board 15 may also control the rotation of the spherical camera body 200 according to instructions from the network side.

[0062] When the camera auxiliary device 23 is a thermal imaging lens or other imaging lens, such as Figure 2 As shown, the extended structure 20 may further include a second sensor board 24. The second sensor board 24 may be electrically connected to the thermal imaging lens or other imaging lens to capture images or video information captured by the thermal imaging lens or other imaging lens. The second sensor board 24 may also be electrically connected to the main control board 15 to transmit the captured image or video information to the main control board 15.

[0063] Regarding the connection between the main housing 11 and the extension housing 21, in a possible embodiment, as shown in FIG. Figure 7 As shown, a portion of the main housing 11 and a portion of the extension housing 21 are nested. In this case, the connection structure 30 includes a fastener 34, which is passed through and fixed to the nested portion of the main housing 11 and the extension housing 21 to securely connect the extension housing 21 to the main housing 11. As a result, the connection area between the main housing 11 and the extension housing 21 is larger, thereby improving the stability of the connection between the main housing 11 and the extension housing 21.

[0064] In one example, Figure 7 As shown, a portion of the main housing 11 extends into the extended housing 21, and the portion of the outer wall of the main housing 11 that extends into the extended housing 21 can contact the inner wall of the extended housing 21. Specifically, the main housing 11 includes a first housing body 111 and a first inner layer 112 fixed within the first housing body 111. The first inner layer 112 is provided with a first threaded hole 1121. The fastener 34 includes a bolt that passes through the extended housing 21, the first housing body 111, and the first inner layer 112 and engages with the first threaded hole 1121. Specifically, the extended housing 21 can be provided with a first through hole 2111, and the first housing body 111 can be provided with a second through hole 1112. The first through hole 2111, the second through hole 1112, and the first threaded hole 1121 are connected. The bolt can sequentially pass through the first through hole 2111, the second through hole 1112, and the first threaded hole 1121 and be tightened within the first threaded hole 1121. This connection structure 30 is relatively simple and secure.

[0065] Furthermore, if Figure 7As shown, the first inner layer 112 extends inward from the end of the first housing body 111 near the extended housing 21 and covers a portion of the first housing body 111. In other words, the dimension of the first inner layer 112 along the first direction Z is smaller than the dimension of the first housing body 111 along the first direction Z. The first direction Z can be the direction from the main structure 10 to the extended structure 20. This provides ample mounting space for the fasteners 34. Furthermore, the dimension of the second inner layer 212 along the first direction Z is not too large, thus saving material and further reducing the cost of the dome camera 1.

[0066] In another example, Figure 8 As shown, a portion of the extended housing 21 extends into the main housing 11, and the portion of the outer wall of the extended housing 21 that extends into the main housing 11 can contact the inner wall of the main housing 11. The extended housing 21 includes a second housing body 211 and a second inner layer 212 fixed within the second housing body 211. The second inner layer 212 is provided with a second threaded hole 2121. The fastener 34 includes a bolt that passes through the main housing 11, the second housing body 211, and the second inner layer 212 and engages with the second threaded hole 2121. Specifically, the main housing 11 can be provided with a second through hole 1112, and the second housing body 211 can be provided with a first through hole 2111. The second through hole 1112, the first through hole 2111, and the second threaded hole 2121 are connected. The bolt can sequentially pass through the second through hole 1112, the first through hole 2111, and the second threaded hole 2121 and be tightened within the second threaded hole 2121. This connection structure 30 is relatively simple and secure.

[0067] Furthermore, if Figure 8 As shown, the second inner layer 212 is disposed inward from the end of the second housing body 211 closest to the main housing 11, and covers a portion of the second housing body 211. In other words, the dimension of the second inner layer 212 along the first direction Z is smaller than the dimension of the second housing body 211 along the first direction Z. This provides ample mounting space for the fastener 34. Furthermore, the dimension of the second inner layer 212 along the first direction Z is limited, thereby saving material and further reducing the cost of the dome camera 1.

[0068] Based on this, Figure 7 and Figure 8As shown, the connection structure 30 also includes a seal 31, which is fixed to the nesting point between the main housing 11 and the extension housing 21 and covers the fastener 34. The seal 31 not only covers the fastener 34 but also the gap between the fastener 34 and the main housing 11 or the extension housing 21, thereby improving the sealing performance. Furthermore, the fastener 34 is not visible from the outside of the dome camera 1, thereby improving the aesthetic appearance of the dome camera 1.

[0069] Regarding the connection between the main housing 11 and the extension housing 21, in another possible embodiment, as shown in FIG. Figure 9 As shown, the connection structure 30 includes a welding portion 32, and the main shell 11 and the extended shell 21 are arranged opposite to each other and fixedly connected by the welding portion 32. In the process of manufacturing the dome camera 1, the main structure 10 and the extended structure 20 can be manufactured first. The main shell 11 in the main structure 10 and the extended shell 21 in the extended structure 20 can both be made of metal materials. Then, the main structure 10 and the extended structure 20 are welded, for example, by laser welding, so as to form a welding portion 32 between the main structure 10 and the extended structure 20, that is, a welding portion 32 is formed between the main shell 11 and the extended shell 21. The welding manufacturing method can, on the one hand, avoid the formation of gaps between the main shell 11 and the extended shell 21, thereby improving the sealing. On the other hand, it can also improve the stability of the connection between the main shell 11 and the extended shell 21.

[0070] Regarding the connection between the main housing 11 and the extension housing 21, in another possible embodiment, as shown in FIG. Figure 10 As shown, the connection structure 30 includes a sealant 33, and the main shell 11 and the extended shell 21 are arranged opposite to each other and fixedly connected by the sealant 33. In the process of manufacturing the dome camera 1, the main structure 10 and the extended structure 20 can be manufactured first. The main shell 11 in the main structure 10 and the extended shell 21 in the extended structure 20 can both be made of plastic materials. Then, the main structure 10 and the extended structure 20 are welded, for example, by ultrasonic welding. As a result, a sealant 33 is formed between the main structure 10 and the extended structure 20, that is, a sealant 33 is formed between the main shell 11 and the extended shell 21. The welding manufacturing method can, on the one hand, avoid the formation of gaps between the main shell 11 and the extended shell 21, thereby improving the sealing performance. On the other hand, it can also improve the stability of the connection between the main shell 11 and the extended shell.

[0071] In some embodiments of the present application, Figure 2As shown, the main housing 11 has a larger dimension along the first direction Z than the extension housing 21. The first direction Z is the direction from the main structure 10 toward the extension structure 20. The imaging lens 12 secured within the main housing 11 is the primary camera lens used to acquire image information. The extension housing 21 can also secure other auxiliary camera components 23, in addition to the primary imaging lens 12. The imaging lens 12 is typically relatively large, so setting the dimension of the main housing 11 along the first direction Z larger than that of the extension housing 21 provides more space for mounting the imaging lens 12.

[0072] like Figure 10 and Figure 11 As shown, the extended structure 20 further includes a bracket 22 and a camera auxiliary device 23. The camera auxiliary device 23 can be, for example, Figure 4 The fill light 231 shown, Figure 5 The auxiliary lens 232 or Figure 6 The speaker 233 shown, etc. The camera auxiliary device 23 can be located in the extended housing 21 and fixed on the bracket 22.

[0073] Regarding the fixed position of the bracket 22, in a possible embodiment, as shown in FIG. Figure 11 As shown, a portion of the bracket 22 extends into and is fixed within the main housing 11, while the remaining portion of the bracket 22 is suspended within the extended housing 21. The auxiliary camera device 23 is fixed to the portion of the bracket 22 that extends into the extended housing 21. Since the main housing 11 is generally large in size along the first direction Z, when a portion of the bracket 22 extends into and is fixed within the main housing 11, the main housing 11 can provide a larger connection area for this portion of the bracket 22, thereby making the bracket 22 more securely fixed within the main housing 11.

[0074] In another possible embodiment, Figure 10 As shown, the bracket 22 is located within the extended housing 21, and the auxiliary camera device 23 is fixed to the extended housing 21 via the bracket 22. Thus, during the production of the extended structure 20, the extended housing 21, bracket 22, and auxiliary camera device 23 can be produced separately. The auxiliary camera device 23 is then mounted on the bracket 22, and the bracket 22 with the auxiliary camera device 23 mounted thereon is then mounted on the extended housing 21, thereby completing the production of the extended structure 20. Next, the produced main structure 10 and the extended structure 20 are fixed together, thereby completing the production of the dome camera 1. Since the bracket 22 is located within the extended housing 21, the process of fixing the main structure 10 and the extended structure 20 is more convenient.

[0075] like Figure 12As shown, the main housing 11 further includes a first partition 113, which is fixed to one end of the first housing body 111 facing the extension housing 21. In this way, the overall structural strength of the main housing 11 is high.

[0076] like Figure 12 As shown, the extended housing 21 further includes a second partition plate 213, which is fixed to one end of the second housing body 211 facing the main housing 11. In this way, the overall strength of the extended housing 21 is higher.

[0077] It will be appreciated that in this embodiment, the main housing 11 includes the first partition 113, and the extension housing 21 includes the second partition 213. In other embodiments, the main housing 11 includes the first partition 113, while the extension housing 21 does not include the second partition 213; or, the main housing 11 does not include the first partition 113, while the extension housing 21 includes the second partition 213.

[0078] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
