Detailed Description
Exemplary embodiments of the present application are described in detail below with reference to examples. However, it should be understood by those skilled in the art that these exemplary embodiments are not meant to limit the present application in any way. Furthermore, the features in the embodiments of the present application may be combined with each other without conflict. The same or similar components are designated by the same reference numerals in the different drawings, and other components are omitted for the sake of brevity, but this does not indicate that the camera housing assembly and the auxiliary assembly tool of the present application may not include other components or parts, nor that the assembly method of the present application may include other steps. It should be understood that the dimensions, proportions and numbers of elements in the drawings are not intended to limit the present application.
The camera housing assembly of the present application is described below with reference to fig. 1 and 2. As shown in fig. 1, the camera housing assembly of the present application may include a housing 10, an optical cover 20, a seal ring 30, a pressure plate 40, and screws 50. The housing 10 may have an inner side, an outer side, and a through hole 12, wherein the inner side of the housing 10 may be used to accommodate the sealing ring 30, the optical cover 20, the pressing plate 40, and a camera (not shown), the outer side of the housing 10 may be used to face the external environment, and the through hole 12 of the housing may be used to protrude the optical cover 20. The optical cover 20 may have a protrusion 21 and a flange 22 extending transversely from the protrusion 21, wherein the protrusion 21 may be disposed to protrude to the outside of the housing 10 through the through hole 12 of the housing 10, and the flange 22 may be disposed to abut against the inside of the housing 10. When the optical cover 20 is mounted to the housing 10, the protrusion 21 of the optical cover 20 forms a space for accommodating the camera so that the camera can be rotated in the space for multi-angle photographing. A sealing ring 30 may be provided between the flange 22 of the optical cover 20 and the inside of the housing 10 to provide a waterproof, dust-proof seal. To facilitate the positioning of the sealing ring 30, the flange 22 of the optical cover 20 and/or the inner side of the housing 10 may be provided with grooves, respectively, as shown in fig. 2. The pressure plate 40 may abut the flange 22 of the optics cage 20 to press the flange 22 of the optics cage 20 against the inside of the housing 10. The platen 40 may include a plurality of screw holes 44, the plurality of screw holes 44 cooperating with a plurality of screws 50 to secure the platen 40 to the housing 10.
According to an embodiment of the present application, as shown in fig. 1 and 2, a plurality of hooks 11 are provided around a through hole 12 at an inner side of the case 10, the plurality of hooks 11 being configured to hold the pressure plate 40 with the case 10 when the pressure plate 40 is positioned with respect to the case 10. As shown in fig. 2, in the assembled state, the edge 47 of the pressing plate 40 is caught by the hook 11 of the housing 10, so that when the optical cover 20 is impacted by an external force, the edge 47 of the pressing plate 40 abuts against the hook 11 without being separated from the housing 10. Thus, the hook 11 of the housing 10 functions to provide explosion-proof performance, and the screw 50 and the seal ring 30 function to provide waterproof and dustproof performance. Accordingly, the hook 11 of the housing 10 can replace the originally designed screw, so that the number of screws used can be reduced, the cost and time can be reduced, and the performance and quality of the product are not reduced. To provide a uniform force distribution, the plurality of hooks 11 and the plurality of screws 50 may be evenly spaced in an alternating manner.
Specifically, the hook 11 of the housing 10 may be provided with a groove 13 facing the through hole 12 to receive the edge 47 of the pressing plate 40, so that the edge 47 of the pressing plate 40 abuts against a sidewall of the groove 13 of the hook 11 when the optical cover 20 is impacted by an external force. In fig. 2, for the purpose of a clear illustration, the edge 47 of the pressure plate 40 is shown with a clearance from the upper side wall of the groove 13 of the hook 11, whereas in the assembled state, the edge 47 of the pressure plate 40 can abut against the upper side wall of the groove 13 of the hook 11 due to the elasticity of the sealing ring 30. The fit between the width of the groove 13 and the thickness of the edge 47 of the pressure plate 40 can be specifically set according to the elasticity of the sealing ring 30 and the required protection performance, and will not be described in detail herein. Of course, the hook pieces 11 of the housing 10 may also take a form other than that shown in fig. 1 and 2, as long as the hook pieces 11 can hook the pressing plate 40 in the assembled state. For example, the groove 13 of the hook 11 may be arranged facing away from the through hole 12 or facing in the circumferential direction of the through hole 12. It should be noted that the location of the hook 11 does not block the installation of the optical cover 20.
Accordingly, as shown in fig. 1 and 2, the pressure plate 40 may be provided with a plurality of openings 41, the plurality of openings 41 being configured to enable the plurality of hooks 11 of the housing 10 to pass through and allow the pressure plate 40 to be positioned relative to the housing 10, for example, by relative rotation. In this way, the pressure plate 40 can be made to press the optical cover 20 against the housing 10 against the flange 22 of the optical cover 20. The opening 41 may be configured to allow the platen 40 to be positioned for rotation relative to the housing 10. Thus, when the pressure plate 40 is positioned with respect to the housing 10, the edge of the pressure plate 40 may be caught by the hook 11, thereby holding the pressure plate 40. To define the portion of the pressure plate 40 caught by the hooks 11, a plurality of first stopping portions 42 may be formed on the pressure plate 40, the plurality of first stopping portions 42 being configured to abut against the plurality of hooks 11 after the pressure plate 40 is positioned with respect to the case 10 to hold the pressure plate 40 and the case 10 together. As shown in fig. 1, first stopping portion 42 may be a portion of edge 47 extending from a sidewall of opening 41. In addition, in order to limit the positioning position of the pressing plate 40 (e.g., limit the angle of rotation of the pressing plate 40), the pressing plate 40 may be further provided with at least one second stopper 43, and the at least one second stopper 43 may be configured to abut against at least one of the plurality of hooks 11 after the pressing plate 40 is positioned with respect to the housing 10 to block the pressing plate 40 from further rotating. As shown in fig. 1, the second blocking portion 43 may be a protruding portion extending laterally from the first blocking portion 42.
In the above-described embodiment shown in fig. 1 and 2, the opening 41 of the pressing plate 40 is a notch, and the first stopping portion 42 and the second stopping portion 43 are stepped-up step portions extending from the sidewall of the opening 41 in the circumferential direction, respectively, however, the present application is not limited thereto. Opening 41 of pressure plate 40 may also be a complete hole, and first and second stoppers 42 and 43 may be stepped down step portions extending circumferentially from the side wall of opening 41. Of course, when the groove 13 of the hook 11 is provided to open toward the circumferential direction of the through hole 12, the hook 11 may be directly hooked on one sidewall of the opening 41, so that the first stopper portion 42 may be provided by a platen surface transverse to the sidewall of the opening 41, and the second stopper portion 43 may be provided by the sidewall of the opening 41.
The platen 40 is a generally flat plate-like member and is typically made of metal. The platen 40 of the present application may be stamped from sheet material such that a protrusion 45 is formed on one side of the platen 40, a recess 46 is formed on the other side of the platen 40, and an edge 47 of the platen 40 is formed transverse to the protrusion 45 and recess 46, as shown in fig. 1 and 2. The opening 41, the first stop portion 42, the second stop portion 43, and the screw hole 44 may all be provided in an edge 47 of the platen 40. In the assembled state, the protrusion 45 of the pressure plate 40 may abut against the flange 22 of the optical cover 20 to press the optical cover 20 against the housing 10. In the embodiment shown in fig. 1, the pressing plate 40 is provided with 4 openings 41, 4 first stopping portions 42 and 4 second stopping portions 43, however, more or fewer openings 41, first stopping portions 42 and second stopping portions 43 may be provided and their numbers may be different, for example, only a smaller number of second stopping portions 43 than openings 41 may be provided, for example, only one second stopping portion 43 may be provided.
The structure of the camera housing assembly of the present application is described above in conjunction with fig. 1 and 2, and the auxiliary assembly tool for assembling the camera housing assembly of the present application is described below with continued reference to fig. 1 and 2 and fig. 8A and 8B.
The auxiliary assembly tool of the present application includes a body 60, and the body 60 may have an end portion that may be provided with a guide pin 61 (as shown in fig. 8A and 8B), and the guide pin 61 may be configured to cooperate with the screw hole 44 on the pressing plate 40 to bring the pressing plate 40 into position relative to the housing 10, for example, by relative rotation. Further, to facilitate positioning of the auxiliary assembly tool with the pressure plate 40 and the housing 10, the body 60 may be provided with a plurality of grooves 63 at a peripheral portion, and the plurality of grooves 63 of the body 60 may be configured to receive the plurality of hooks 11 of the housing 10. In this way, when the hook 11 of the housing 10 is positioned in the slot 63 of the body 60, for example, abutting against one side of the slot 63, it can be determined that the guide pin 61 of the body 60 will be aligned with the screw hole 44 of the pressure plate 40 since the hook 11 of the housing 10 has passed through the opening 41 of the pressure plate 40. By turning the auxiliary assembly tool, the pressing plate 40 can be turned so that the edge 47 of the pressing plate 40 is caught by the hook 11 and held with the housing 10.
Further, the end of the body 60 of the auxiliary assembly tool is also provided with a protruding portion 62, and the protruding portion 62 may be set such that the guide pin 61 can be inserted into the screw hole 44 of the pressure plate 40 when the protruding portion 62 of the body 60 is mated with the recessed portion 46 of the pressure plate 40. On the contrary, when the protruding portion 62 of the body 60 is mated with the protruding portion 62 of the platen 40, the guide pins 61 cannot be inserted into the screw holes 44 of the platen 40. In this way, the auxiliary assembly tool can function as a mistake proofing tool to help the operator check whether the pressure plate 40 is correctly placed, so that the operator's mistake can be further reduced and the assembly quality can be improved. The fitting of the auxiliary assembly tool to the pressure plate 40 will be described in further detail later in the description of the assembly method of the present application with reference to fig. 8A and 8B.
Based on the camera housing assembly and the auxiliary assembly tool of the present application, the assembly method of the present application can be realized. The method of assembling the camera housing assembly with the auxiliary assembly tool of the present application is further described below with reference to fig. 3-7.
As shown in fig. 3, the sealing ring 30 is first placed on the inner side of the housing 10, and if the housing 10 has a groove, the sealing ring 30 may be placed in the groove of the housing 10 (as shown in fig. 2); the optical cover 20 is then placed on the through-hole 12 of the housing 10 (in the direction of the arrow in the left part of fig. 3), with the protrusion 21 of the optical cover 20 protruding from the through-hole 12, and the flange 22 of the optical cover 20 abutting against the inside of the housing 10 (as shown in the right part of fig. 3).
Then, as shown in fig. 4, the pressing plate 40 is placed on the inner side of the housing 10 (in the direction of the arrow in the left part of fig. 4) so that the pressing plate 40 abuts against the flange 22 of the optical cover 20 (as shown in the right part of fig. 4). It should be noted that when the pressure plate 40 is placed, the opening 41 of the edge 47 of the pressure plate 40 should be aligned with the hook 11 of the housing 10 (e.g., with the hook 11 abutting against one side of the opening 41).
Next, the auxiliary assembly tool is placed on the pressing plate 40, and the guide pins 61 of the body 60 of the auxiliary assembly tool are inserted into the screw holes 44 of the pressing plate 40, as shown in fig. 5. To facilitate alignment of the guide pins 61 of the auxiliary assembly tool with the screw holes 44 of the pressure plate 40, it is possible to use the grooves 63 on the peripheral portion of the body 60 of the auxiliary assembly tool to align with the hooks 11 of the housing 10. When the plurality of grooves 63 on the peripheral portion of the body 60 of the auxiliary assembly tool are aligned with the plurality of hooks 11 of the housing 10, it can be determined that the guide pins 61 of the auxiliary assembly tool will be aligned with the screw holes 44 of the pressing plate 40.
Then, as shown in fig. 6, the auxiliary assembly tool is rotated so that the pressure plate 40 is rotated with respect to the housing 10 until the pressure plate 40 is positioned with respect to the housing 10, that is, the rotation of the pressure plate 40 is blocked. For example, the second stopper 43 is in contact with the hook 11.
It should be noted that the auxiliary assembly tool may function as a mistake proofing tool to check whether the platen 40 is placed correctly in this step. For example, if the platen 40 is placed correctly, as in the correct fit state shown in fig. 8A, the protrusion 62 of the auxiliary assembly tool is fitted into the recess 46 of the platen 40, so that the guide pin 61 of the auxiliary assembly tool is aligned with and inserted into the screw hole 44 of the platen 40 (as shown in the circle in fig. 8A), and the platen 40 can be brought into rotation relative to the housing 10. On the contrary, if the platen 40 is placed incorrectly, as in the misfitted state shown in fig. 8B, the projection 62 of the auxiliary assembly tool comes into contact with the projection 45 of the platen 40, so that the guide pin 61 of the auxiliary assembly tool cannot be inserted in alignment with the screw hole 44 of the platen 40 (as shown in the circle in fig. 8B), and the platen 40 cannot be rotated. At this point, the operator may immediately detect the error and turn the platen 40 over, which ensures proper installation and time savings.
The auxiliary assembly tool is then removed and the screws 50 are installed to secure the housing 10, the seal ring 30, the optical cover 20, and the pressure plate 40 together to form the camera housing assembly of the present application.
Compared with the existing camera shell assembly, the camera shell assembly and the assembling method change the assembling relation between the shell and the pressing plate, and the pressing plate is kept in advance and horizontal by the hook-shaped piece of the shell, so that an operator on a production line can easily fasten screws without keeping the balance of the pressing plate by hands, thereby reducing the error of the operator and improving the assembling quality. In addition, the auxiliary assembling tool can enable the pressing plate to be positioned at the correct position more easily, and can be used as a mistake-proofing tool to help an operator to check whether the pressing plate is placed correctly, so that the error of the operator can be further reduced, and the assembling quality can be improved. Moreover, the camera housing assembly of the present application can halve the number of screws originally planned, thereby significantly reducing production costs and production time. Furthermore, the hooks on the housing not only serve to retain the pressure plate, but also assume the same role as the screws being replaced to meet the IK10 protection level requirements. Meanwhile, the rest screws and sealing rings can meet the requirement of IP66 protection grade. Thus, cost and time can be saved without degrading the product quality.
The present application is described in detail above with reference to specific embodiments. It is to be understood that both the foregoing description and the embodiments shown in the drawings are to be considered exemplary and not restrictive of the application. For example, the present application has been described in the preferred embodiment with reference to an outdoor camera or a video surveillance camera, but the present application is not limited to such a camera housing, but can be applied to any field of camera housings requiring explosion-proof performance and waterproof and dustproof performance. It will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit of the application, and these changes and modifications do not depart from the scope of the application.
