Description

Technical Field

[0001] The present invention relates to the technical field of camera structures, and in particular to a camera installation and positioning method, an installation auxiliary tool, and a camera. Background Art

[0002] A camera primarily consists of front and rear covers and other structural components, as well as an internal PCB board. A typical camera's internal structure involves installing the various PCB boards onto the front and rear covers, which are then closed and connected via connectors on the PCB boards. During the actual assembly process, positional errors between the PCB boards and the structural components of the housing can lead to misalignment of the front and rear covers after installation. The more layers of PCB boards are stacked, the more pronounced the error. Misalignment of the front and rear covers significantly affects the product's appearance, and the mounting holes will shift as a result. During actual installation, bolts will forcibly correct the offset structure, causing a certain degree of torsional force in the connectors between the PCB boards, leading to poor contact later on. Severe misalignment can prevent the front and rear covers from being properly installed.

[0003] The direct positioning between structural parts in the existing technology only utilizes machining accuracy, which can well ensure the relative position of the front and rear covers. However, the positioning and installation of the PCB board in the camera will lack precise control, and there may still be stress between the PCB board connectors.

[0004] There are usually three ways to circumvent this:

[0005] 1. All PCBs are directly mounted on the front or rear cover, and no other structural components are in direct contact with the PCBs;

[0006] 2. Soft connections are used between PCB boards, so there is no need to consider connector issues;

[0007] 3. Floating connectors are used between PCB boards to achieve displacement compensation within the error range.

[0008] The above three installation and connection schemes each have the following disadvantages, specifically:

[0009] 1. All PCBs are mounted on a structural component on one side. Due to the ±0.15mm machining error in PCB thickness, the cumulative height deviation from the theoretical value is large. This solution cannot meet the requirements of products such as cameras that require internal heat dissipation, sealing, or have high requirements for the distance between the PCB and the structural component.

[0010] 2. Soft connections are used between PCB boards. Soft connectors are more expensive, easily damaged, and have lower installation and welding efficiency than hard connections.

[0011] 3. The floating connector itself is large in size and is not suitable for products with smaller dimensions.

[0012] During the installation process, experimental verification found that the allowable error range of the front and rear cover structural components is ±0.13mm. Therefore, for occasions where high installation accuracy is required, the above solutions are not suitable for use in products such as cameras, and cannot effectively control the misalignment error of the front and rear covers after installation while ensuring the connection of the connectors.

[0013] In summary, in the prior art, there is a lack of an installation method for multi-PCB camera installation that can meet the installation accuracy requirements, meet the various performance requirements of the camera, and reduce costs. Summary of the Invention

[0014] The object of the present invention is to provide a camera installation and positioning method, an installation auxiliary tool and a camera, which can achieve precise positioning and installation between multiple PCB boards and housings, and between each housing, by using the internal and external positioning features of the camera and related auxiliary tools used in conjunction with the installation method, so as to solve the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0055] like Figures 1 to 5 As shown, the present invention provides a camera including a camera front cover 1, a camera rear cover 2, a middle frame shell 3 and multiple PCB boards; wherein, the camera shell refers to the camera front cover 1, the camera rear cover 2 and the middle frame shell 3, the camera front cover 1 and the camera rear cover 2 are collectively referred to as two half shells, and the middle frame shell 3 is arranged between the two half shells; the half-shell PCB board refers to the PCB board installed in the two half shells, namely the rear cover PCB board 7 and the front cover PCB board 9.

[0056] The middle frame case 3 is provided with a mounting boss 301. The mounting boss 301 reduces the contact area between the middle frame case PCB board 8 and the middle frame case 3, thereby facilitating the positioning and installation of the middle frame case PCB board 8 in the middle frame case 3. The mounting boss 301 is provided with a positioning pin hole 302 for installing the middle frame case PCB board 8. The positioning pin hole 302 cooperates with the positioning pin 303 to roughly locate the position of the middle frame case PCB board 8 on the middle frame case 3.

[0057] A mounting and locking bolt is provided between the middle frame case 3 and the middle frame case PCB board 8. The bolt is a stud bolt 11 that can be screwed at both ends and is used to adjust the locking degree of the middle frame case PCB board 8 in the middle frame case 3. Figure 5 The stud 11 has slots 1101 at both ends for applying force with a screwdriver. The stud 11 can be tightened or loosened using both ends. When the PCB 8 is installed in the middle frame housing 3, the end of the stud 11 inside the middle frame housing 3 is loosened. After the PCB 8 is positioned horizontally within the middle frame housing 3 using the positioning features between the PCB 8 and the middle frame housing 3 or with the assistance of the PCB positioning tool 12, the PCB 8 is locked in place by tightening the end of the stud 11 outside the middle frame housing 3.

[0058] According to actual requirements, the middle frame shell 3 can be provided with a plurality of sub-frame shells that cooperate with each other. One or more PCB boards are fixedly mounted on the sub-frame shells, and every two PCB boards are positioned and connected via a connector 10 .

[0059] The interface between the middle frame 3 and the two half-shells features a concave-convex structure. This structure consists of a protruding edge on one side and a groove on the other, allowing the protruding edge to fit neatly into the groove, increasing the contact area at the interface. This structure helps position the middle frame 3 and the two half-shells, while also achieving a sealed connection between the camera housing and protecting the camera's internal components from dust and water.

[0060] The four corners of the camera front cover 1 are each provided with a front cover groove 101 , and the front cover groove 101 is provided with a mounting hole, through which the fixing member 6 passes, thereby achieving the overall assembly of the camera housing.

[0061] The present invention provides a method for positioning and installing a camera. The method is applied to the precise positioning and fixed installation of multiple PCBs built into a camera. The camera is disassembled into three parts: a camera front cover 1, a camera rear cover 2, and a middle frame shell 3. The PCBs are sequentially installed in the three parts. The positional relationship of the three parts is defined by positioning features such as a boss and a positioning pin 303 inside the camera, or by using an external positioning structure, thereby achieving assembly of the camera shell without offset.

[0062] like Figures 1 to 7 As shown, the positioning and installation method of multiple PCB boards in the camera is as follows:

[0063] First, the upper PCB 801 of the middle frame case is secured to the mounting boss 301 of the middle frame case 3 using stud bolts 11. The upper PCB 801 is roughly positioned on the middle frame case 3 by means of the transitional fit between the waist-shaped openings on the upper PCB 801, the locating pin holes 302 on the mounting boss 301, and the locating pins 303. Similarly, the lower PCB 802 is roughly positioned on the middle frame case 3 using the same procedure. The alignment between the connector 10 on the upper PCB 801 and the connector 10 on the lower PCB 802 ensures an accurate and stable connection between the two connectors 10. Specifically, the two connectors 10 are connected according to the corresponding mating structure, free from external lateral forces and torsional deformation that can cause unstable connections after long-term use. This ensures the precise installation of the upper PCB 801 and lower PCB 802. After the position of the middle frame PCB 8 in the middle frame 3 is determined, the end of the stud bolt 11 on the outside of the middle frame 3 is tightened to lock the middle frame PCB 8 in the middle frame 3 , thus completing the positioning and installation of the middle frame PCB 8 on the middle frame 3 .

[0064] There are two methods for positioning and installing the middle frame 3 and the half-shell PCB boards in the two half-shells: positioning and installing from the inside out and positioning and installing from the outside in. Taking the positioning and installing the rear cover PCB board 7 of the middle frame 3 as an example, the above two positioning and installing methods are explained as follows:

[0065] Inside-out positioning and installation: By aligning the connector 10 on the lower PCB board 802 of the middle frame case with the connector 10 on the rear cover PCB board 7, an accurate and stable connection between the connectors 10 is ensured, guaranteeing the precise installation between the lower PCB board 802 and the rear cover PCB board 7. Specifically, after installation, the connectors 10 are protected from external forces in the lateral direction and from torsional deformation, thus preventing electrical connection problems or desoldering between the connectors 10. Driven by the connector 10 on the rear cover PCB board 7, the rear cover PCB board 7 is placed on the mounting surface of the camera rear cover 2. At this point, the relative position of the rear cover PCB board 7 is determined, and the rear cover PCB board 7 is secured with the mounting bolts 5. Finally, the middle frame case 3 and the camera rear cover 2 are assembled.

[0066] Similarly, according to the above-mentioned inside-out positioning and installation method, the positioning and installation between the PCB board 801 on the middle frame shell and the front cover PCB board 9 are first determined, and then the positioning and installation of the front cover PCB board 9 between the camera front cover 1 are completed. Finally, the middle frame shell 3 and the camera front cover 1 are assembled.

[0067] Outside-in positioning and installation method: The inside-out positioning and installation method is to first install and position the rear cover PCB board 7 inside the camera rear cover 2, and then assemble the middle frame shell 3 and the camera rear cover 2. The positioning and installation of the rear cover PCB board 7 inside the camera rear cover 2 can utilize the positioning features between the camera rear cover 2 and the rear cover PCB board 7, or use the PCB board positioning tool 12. The details are as follows:

[0068] Example 1

[0069] like Figure 6 and Figure 7 As shown, the PCB board positioning tool 12 is composed of four positioning plates, which are nested in pairs. The first positioning plate 1201 has a step on its surface, and a side through-slot 12012 is provided on the side of the upper end of the step. This side through-slot 12012 cooperates with the planar structure of the second positioning plate 1202, allowing the two positioning plates to be installed in a nested manner. The second positioning plate 1202 is adjusted and fixed on the camera back cover 2 by a first fastener 1205. The lower end of the step has a planar through-slot 12011, which is provided with an adjustment block 1203. A second fastener 1206 is provided on one side of the adjustment block 1203 to determine the position of the adjustment block 1203 on the planar through-slot 12011. A gap plate 1204 is provided on the other side of the adjustment block 1203 to control the distance between the PCB board positioning tool 12 and the camera back cover 2.

[0070] The PCB positioning fixture 12 is used to assist in installing the rear cover PCB 7 inside the camera rear cover 2. The specific method is as follows: Place the camera rear cover 2 below the PCB positioning fixture 12. Use the first fastener 1205 to adjust and determine the length of the second positioning plate 1202 on the camera rear cover 2. Similarly, adjust and determine the lengths of the other three positioning plates on the camera rear cover 2 so that the PCB positioning fixture 12 matches the size of the camera rear cover 2, facilitating the positioning of the rear cover PCB 7. Simultaneously, move the adjustment block 1203 on the first positioning plate 1201 so that both the adjustment block 1203 and the gap plate 1204 are within the length range of the camera rear cover 2. Use the third fastener 1207 to adjust the length of the gap plate 1204 to ensure that the gap plate 1204 is inside the camera rear cover 2. Use the gap plate 1204 to control the distance between the PCB positioning fixture 12 and the camera rear cover 2, thereby protecting the camera rear cover 2 and facilitating the positioning and installation of the rear cover PCB 7 inside the camera rear cover 2.

[0071] Similarly, the adjustment blocks 1203 and gap plates 1204 set on the other three positioning plates are adaptively adjusted to match the installation of the rear cover PCB board 7 in the camera rear cover 2, so that during and after the installation process, the components on the rear cover PCB board 7 are accurately positioned without loss, and the rear cover PCB board 7 can work normally.

[0072] After determining the installation position of the rear cover PCB 7 within the camera back cover 2, the rear cover PCB 7 is secured within the camera back cover 2 using the mounting bolts 5. At this point, the rear cover PCB 7 is electrically connected to the connector 10 on the back cover PCB 7 and the connector 10 on the lower PCB 802 of the middle frame housing, completing the positioning connection between the rear cover PCB 7 and the lower PCB 802 of the middle frame housing. The camera back cover 2 and middle frame housing 3 are then assembled.

[0073] Similarly, the PCB board positioning tool 12 is also suitable for assisting the installation of the front cover PCB board 9 in the camera front cover 1, or assisting the installation of the middle frame case PCB board 8 in the middle frame case 3.

[0074] Among them, the assembly between the two half shells and the middle frame shell 3 is carried out by the matching parts that limit the installation position in the camera shell, such as the positioning pin 303 and the positioning pin hole 302, the positioning boss and the positioning groove, to position the shell itself; or the camera shell is positioned by using the external positioning tooling that matches the characteristic structure of the camera shell surface, such as the shell surface interface, mounting holes, heat dissipation fins, characteristic steps 4 and the camera ring base; after the positions of the three parts of the camera shell are determined, the fixing part 6 is installed from the camera front cover 1 to complete the locking and fixation of the entire camera.

[0075] like Figures 8 to 11As shown, the camera housings are positioned and assembled as a whole using the external positioning fixture and the characteristic structure of the camera housing surface. The specific method is as follows:

[0076] Example 2

[0077] like Figure 8 and Figure 9 As shown, the main body of the L-shaped external positioning tooling 13 in Example 2 is an L-shaped structure, and the L-shaped external positioning tooling 13 includes an L-shaped external positioning tooling base 1301 and an L-shaped external positioning tooling side wall. The side wall grooves 1302 of different heights opened in the L-shaped external positioning tooling side wall are provided with fixed blocks 1303 of different heights and thicknesses and threaded holes 1304 of different heights and positions.

[0078] The camera adapter base is placed within the airtight design of the L-shaped external positioning fixture base 1301. Simultaneously, a corner of the camera is placed within the L-shaped structure. Based on the dimensions of the camera's front and rear covers, and other structural components, a threaded hole 1304 of appropriate height and position is selected to adjust the position of the fixing block 1303 within the sidewall groove 1302. This positional relationship between the fixing block 1303 and the characteristic step 4 on the camera housing surface is then matched to position each camera housing, including the positioning between the camera front cover 1 or the camera rear cover 2 and the middle frame shell 3, as well as the overall positioning of the three. The operator manually presses the camera onto the L-shaped external positioning fixture 13 to define its position on the L-shaped external positioning fixture 13. The fixing member 6 is then installed on the camera front cover 1 to secure the different housings or to lock the entire camera.

[0079] In the L-shaped external positioning tool 13 in Example 2, the air-avoidance design of the L-shaped external positioning tool base 1301 matches the structure of the camera ring base to complete the rough positioning; by adjusting the position of the fixed block 1303 on the side wall of the tool in the L-shaped external positioning tool 13 on the side wall groove 1302, the fixed block 1303 is matched with the characteristic step 4 of the camera housing to determine the position between the camera housings.

[0080] Example 3

[0081] In order to further simplify the positioning and installation of the camera housing by the external positioning tool, a baffle-type external positioning tool 14 is provided in Example 3, which does not require the assistance of external force to position each camera shell, including the positioning between the camera front cover 1 or the camera rear cover 2 and the middle frame shell 3, as well as the overall positioning between the three.

[0082] like Figure 10As shown, a D-shaped through hole 1401 is provided in the center of the bottom plate of the baffle-type external positioning tool 14 for placing the camera ring base; a first slide groove 1402 and a second slide groove 1405 are provided on the adjacent two sides of the D-shaped through hole 1401, and a first baffle 1403 is provided on the first slide groove 1402; a second baffle 1404 is provided on the second slide groove 1405, and the first baffle 1403 and the second baffle 1404 cooperate with their respective slide grooves to limit the position of the camera on the baffle-type external positioning tool 14; a first baffle step 14031 and a second baffle step 14041 are respectively provided on the first baffle 1403 and the second baffle 1404, which match the characteristic step 4 on the surface of the camera shell to position each camera shell.

[0083] Taking the overall positioning and assembly of the camera as an example, the auxiliary positioning process of the baffle-type external positioning tool 14 for the entire camera is briefly described, specifically as follows: the camera ring base is placed in the D-shaped through hole 1401 of the baffle-type external positioning tool 14, and according to the size of the camera housing, the position of the first baffle 1403 on the first slide groove 1402 and the position of the second baffle 1404 on the second slide groove 1405 are adjusted so that the first baffle 1403 and the second baffle 1404 can limit the position of the camera housing on the baffle-type external positioning tool 14; then the first baffle step 14031 and the second baffle step 14041 are respectively matched with the characteristic step 4 on the surface of the camera housing to determine the position of the camera housing; after determining the position of the camera housing, the fixing part 6 is installed from the camera front cover 1 to complete the locking and fixation of the entire camera.

[0084] Example 4

[0085] like Figure 11 As shown, in order to realize the external positioning tool to directly position the camera housing, on the basis of Example 2 and Example 3, Example 4 provides an inclined external positioning tool 15 to position each camera shell, including the positioning between the camera front cover 1 or the camera rear cover 2 and the middle frame shell 3, as well as the overall positioning between the three.

[0086] The inclined external positioning tooling 15 includes an inclined external positioning tooling side wall 1501 and an inclined external positioning tooling base 1502, and the inclined external positioning tooling side wall 1501 and the inclined external positioning tooling base 1502 are L-shaped; the opening of the inclined external positioning tooling base 1502 of the inclined external positioning tooling 15 is higher than the corner formed by the inclined external positioning tooling side wall 1501 and the inclined external positioning tooling base 1502, so that the inclined external positioning tooling base 1502 of the inclined external positioning tooling 15 has a certain tilt angle.

[0087] The side of the tilted external positioning fixture base 1502 is provided with an oblique section 1504, which is used to place the camera ring base and roughly locate the position of the camera housing on the tilted external positioning fixture 15. The tilted external positioning fixture side wall 1501 is provided with an inclined external positioning fixture side wall groove 15011 on each side of the corner. The inclined external positioning fixture side wall groove 15011 is provided with a positioning threaded hole 15012 and a positioning block 1503. The positioning threaded hole 15012 determines the position of the positioning block 1503 within the tilted external positioning fixture side wall groove 15011; the positioning block 1503 can be used to match the characteristic step 4 on the surface of the camera housing to position the camera housing. The tilted external positioning fixture 15 uses the camera's own gravity to further determine the position of the camera on the tilted external positioning fixture 15. After the camera housing is positioned, the fixing member 6 is installed from the camera front cover 1 to complete the locking and fixing of the entire camera.

[0088] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
