Description

Technical Field

[0001] This application relates to the technical field of electronic products, and more particularly to a lifting bracket, camera assembly, and electronic device. Background Technology

[0002] In existing technologies, to increase screen area, some mobile phones, tablets, and other electronic devices typically employ a pop-up camera design. This pop-up camera uses a lifting bracket to raise and lower the camera module, achieving a concealed installation within the device's storage compartment. The lifting bracket requires mounting slots to accommodate the camera module components. These slots have complex structures, with varying depths, shapes, limiting structures, and positioning structures at different locations. For example, some slots may have shaft grooves for mounting hinges, while others may have positioning posts or steps for positioning the camera module components. Currently, the entire lifting bracket is machined using CNC machining to ensure overall precision, guaranteeing both aesthetic appeal and lifting accuracy.

[0003] Because the lifting bracket has a complex structure, CNC machining takes a long time and is costly. Some lifting brackets are manufactured using injection molding or die casting, but these methods result in lower structural stability and machining accuracy, making them prone to deformation. This not only fails to guarantee the aesthetic appearance of the lifting bracket but also increases the friction between the lifting bracket and the inner wall of the storage tank, significantly reducing lifting accuracy and even affecting the sealing and dustproof performance of the storage tank.

[0027] For ease of description, the up and down directions mentioned below are... Figure 1 Its vertical direction is consistent with the horizontal direction mentioned below. Figure 1 Its left-right direction is consistent, and the front-back direction mentioned below is consistent with it. Figure 1 Their projection directions are consistent.

[0028] like Figures 1 to 3 As shown, this embodiment provides a lifting bracket, including a lifting seat 1 and a sleeve 2.

[0029] The lifting base 1 has a first shooting hole 102 and a mounting slot 101. The mounting slot 101 communicates with the first shooting hole 102. The mounting slot 101 of the lifting base 1 is used to install and support the camera module 4, and the first shooting hole 102 facilitates the camera of the camera module 4 to take pictures.

[0030] The mounting base 2 has a slot 201 and a second shooting hole 202 communicating with the slot 201. After the mounting base 2 is installed on the lifting base 1, the first shooting hole 102 communicates with the second shooting hole 202, and the mounting groove 101 communicates with the opening of the slot 201. The camera can take pictures through the first shooting hole 102 and the second shooting hole 202. The camera module 4 is installed in the mounting groove 101 from the opening of the slot 201.

[0031] The sleeve 2 is fitted onto the lifting base 1 via the sleeve groove 201, thus assembling the lifting base 1 and the sleeve 2. The sleeve 2 is fitted onto the outside of the lifting base 1. When the lifting bracket of the electronic device rises, the sleeve 2 and a part of the lifting base 1 extend from the inside of the electronic device to the outside of the electronic device. The sleeve 2 can fit onto the extended part of the lifting base 1.

[0032] This application divides the lifting bracket into a lifting seat 1 and a sleeve 2. The sleeve 2 can be integrally formed by CNC machining. CNC (Computerized Numerical Control) is an automation technology that uses computers to achieve digital program control, widely used in the field of machining. Currently, CNC machining is generally performed using CNC machine tools and CNC lathes. The lifting seat 1 can be integrally formed by die casting or injection molding; that is, the lifting seat 1 can be integrally formed by plastic injection molding or by zinc alloy / magnesium alloy / aluminum alloy die casting. Even complex components can be processed quickly, with simple processing steps and relatively low cost.

[0033] The sleeve 2 is fitted onto the lifting base 1. The sleeve 2, as the outer contour of the extended portion 112 of the lifting bracket, not only serves as an exterior decoration but also slides smoothly with the electronic equipment. The sleeve groove 201 of the sleeve 2 is a square groove, and the bottom wall 204 of the sleeve groove 201 only has round or oblong holes as slots. The sleeve 2 is small in size and simple in structure, requiring fewer machining steps. Therefore, CNC machining of the sleeve 2 does not result in long machining time or excessive cost. At the same time, this machining process offers high precision. When the lifting bracket is used on electronic equipment, it ensures the structural strength and lifting accuracy of the lifting bracket, as well as the sealing and dustproof performance of the electronic equipment.

[0034] In this application, the lifting base 1 has a mounting slot 101 for mounting the camera module 4, and the structure of the lifting base 1 is relatively complex. Therefore, the lifting base 1 can be processed by die casting or injection molding, which reduces the processing difficulty and cost and improves production efficiency. At the same time, the lifting base 1 is covered by a CNC-machined sleeve 2, which ensures the lifting accuracy, sealing performance and dustproof performance of the lifting bracket and electronic equipment.

[0035] Thus, by using different processes to process the lifting seat 1 and the sleeve 2 of the lifting bracket, this application not only ensures the aesthetic appearance of the lifting bracket and reduces production costs, but also improves the lifting accuracy, sealing performance and dustproof performance of the lifting bracket.

[0036] In one embodiment, the sleeve 2 has a first engaging portion 203 in its groove 201, and the lifting seat 1 has a second engaging portion 103. The first engaging portion 203 engages with the second engaging portion 103. When the sleeve 2 is fitted onto the lifting seat 1, the first engaging portion 203 engages with the second engaging portion 103, thereby achieving the installation and positioning of the sleeve 2, improving the stability of the sleeve 2 installed on the lifting seat 1, and preventing the sleeve 2 from separating from the lifting seat 1 and falling off during the lifting process.

[0037] Optionally, a slot is provided at the first engaging part 203, and a block is provided at the second engaging part 103. When the sleeve 2 is fitted onto the lifting seat 1, the block engages with the slot, enabling the sleeve 2 to be detachably installed on the lifting seat 1. The slot can be circular or racetrack-shaped to prevent the sleeve 2 from rotating. In this application, there are multiple slots, some of which are circular and some are racetrack-shaped, further improving the stability of the sleeve 2 installed on the lifting seat 1.

[0038] It is understandable that the positions of the slot and the block can be interchanged. In this application, the slot is set on the socket 2. Compared with setting the block on the socket 2, it is simpler to open the slot on the socket 2 when using CNC machining.

[0039] Optionally, the sleeve groove 201 of the sleeve 2 has a bottom wall 204, and a first engaging portion 203 is located on the bottom wall 204. The bottom wall 204 is arranged facing forward. The lifting seat 1 has an abutment surface 104 and a mounting surface 105. The abutment surface 104 and the mounting surface 105 are opposite to each other, and the abutment surface 104 is located on the rear side of the lifting seat 1. The mounting surface 105 is located on the front side of the lifting seat 1. The mounting groove 101 is provided on the mounting surface 105, and the second engaging portion 103 is located on the abutment surface 104. The second engaging portion 103 engages with the first engaging portion 203 on the bottom wall 204 from front to back, restricting the up and down movement of the sleeve 2. When the lifting seat 1 is raised and lowered, the friction between the sleeve 2 and the electronic equipment, and the inertia generated by the lifting seat 1, will not cause the sleeve 2 to loosen or fall.

[0040] Furthermore, the contact surface 104 is provided with a pad 106, which is integrally formed with the lifting seat 1. The pad 106 abuts against the bottom wall 204 to form a glue-filling space between the contact surface 104 and the bottom wall 204. During the installation of the sleeve 2 on the lifting seat 1, glue is added to the contact surface 104 or the bottom wall 204 of the sleeve groove 201. After the sleeve 2 is installed on the lifting seat 1, the glue-filling space is filled with glue, which improves the stability of the sleeve 2 installed on the lifting seat 1.

[0041] In one embodiment, the sleeve groove 201 of the sleeve 2 further has a first sidewall 205, a second sidewall 206, and a third sidewall 207 connected in sequence. The first sidewall 205 and the second sidewall 206 are arranged at intervals from left to right, with the first sidewall 205 and the second sidewall 206 facing each other. The second sidewall 206 is located above the first sidewall 205 and the second sidewall 206. The first sidewall 205, the second sidewall 206, and the third sidewall 207 are all connected to the bottom wall 204.

[0042] The lifting seat 1 also has a first side 107, a second side 108, and a third side 109 connected in sequence. The first side 107 and the third side 109 are opposite to each other. The first side 107, the second side 108, and the third side 109 are all connected to the abutment surface 104 and the mounting surface 105. The first side 107 is provided with a first protruding rib 116 abutting against the first side wall 205 and / or the second side 108 is provided with a second protruding rib 117 abutting against the second side wall 206 and / or the third side 109 is provided with a third protruding rib 118 abutting against the second side wall 206. The first protruding rib 116, the second protruding rib 117, and the third protruding rib 118 can be provided simultaneously, or one or two of them can be provided.

[0043] Since the lifting seat 1 is formed by die casting or injection molding, the first rib 116, the second rib 117, and the third rib 118 are all provided on the lifting seat 1. Even if the structural complexity of the lifting seat 1 is increased, the production efficiency and cost will not be increased.

[0044] In this application, the first protruding rib 116, the second protruding rib 117, and the third protruding rib 118 are simultaneously provided, and there are multiple first protruding ribs 116, second protruding ribs 117, and third protruding ribs 118. Multiple first protruding ribs 116 are arranged at intervals from top to bottom, multiple third protruding ribs 118 are arranged at intervals from top to bottom, and multiple second protruding ribs 117 are arranged at intervals from left to right. The first protruding ribs 116, second protruding ribs 117, and third protruding ribs 118 are integrally formed with the lifting seat 1. The first protruding ribs 116, second protruding ribs 117, and third protruding ribs 118 respectively abut against the first side wall 205, the second side wall 206, and the third side wall 207, thereby improving the fitting accuracy and installation stability of the sleeve 2 installed on the lifting seat 1.

[0045] Optionally, the lifting seat 1 has a transmission part 111 and an extension part 112. The extension part 112 is used to extend out of the electronic device, and the transmission part 111 is used to indirectly or directly connect to the drive module 6 to realize the lifting of the lifting seat 1. The sleeve 2 only needs to cover the exposed part of the extension part 112, and the length of the sleeve 2 can be relatively short.

[0046] The contact surface 104, mounting surface 105, first side surface 107, second side surface 108, and third side surface 109 are all located in the protrusion 112. The transmission part 111 has a positioning surface 114. When the sleeve 2 is fitted onto the protrusion 112 of the lifting seat 1 through the sleeve groove 201, the lower end of the sleeve 2 abuts against the positioning surface 114, thereby realizing the installation and positioning of the sleeve 2.

[0047] Furthermore, the transmission part 111 is provided with a boss 113, and a positioning surface 114 is located on the boss 113. The boss 113 is also provided with a connecting surface 115. The transmission part 111 is connected to the connecting surface 115 of the boss 113. The connecting surface 115, the first side wall 205, the second side wall 206, and the third side wall 207 are all arranged around the protrusion 112, and the connecting surface 115, the first side wall 205, the second side wall 206, and the third side wall 207 all extend in a direction away from the bottom wall 204 and protrude from the protrusion 112. When the sleeve 2 is fitted on the lifting seat 1, the sleeve 2 completely covers the abutment surface 104, the first side 107, the second side 108, and the third side 109 of the lifting seat 1. That is, the protrusion 112 of the lifting seat 1 and the mounting groove 101 are both located in the sleeve groove 201 of the sleeve 2, which prevents the protrusion 112 of the lifting seat 1 from being exposed and protects the protrusion 112 of the lifting seat 1. The mounting surface 105 and the first side wall 205, the second side wall 206 and the third side wall 207 all form an L-shaped stepped surface, which facilitates the installation and positioning of the camera module 4.

[0048] Optionally, the connection between the first sidewall 205 and the second sidewall 206, and the connection between the second sidewall 206 and the third sidewall 207, are provided with inner rounded corners 208. The connection between the first sidewall 107 and the second sidewall 108, and the connection between the second sidewall 108 and the third sidewall 109, are provided with outer rounded corners 110 that match the inner rounded corners 208. The cooperation between the outer rounded corners 110 and the inner rounded corners 208 not only facilitates the guidance during the assembly of the sleeve 2 and the lifting seat 1, but also reduces stress concentration after the sleeve 2 and the lifting seat 1 are assembled, improves contact performance, and thus improves the reliability and service life of the components.

[0049] Optionally, the lifting bracket also includes a transmission base 3. The transmission base 3 is used to connect to the output end of the drive module 6. The transmission base 3 is provided with a plurality of positioning holes 301 spaced apart. The transmission base 3 has a connecting end, which is provided with a glue-pulling position and / or glue-pulling hole.

[0050] The transmission seat 3 has a slender structure. In order to ensure the strength of the transmission seat 3, the transmission seat 3 is made of one piece of metal to avoid warping deformation.

[0051] The transmission unit 111 is connected to the transmission seat 3 via injection molding. During injection molding, the positioning holes 301 are used for positioning the lifting seat 1. These holes allow for more accurate positioning of the transmission seat 3 on the injection mold. The larger spacing between the multiple positioning holes 301 improves positioning accuracy. After the transmission seat 3 is installed on the injection mold, the lifting seat 1 is then formed by injection molding. The pull-out area is a groove located at the edge of the connection end. The pull-out area and / or pull-out holes enhance the bonding force between the plastic and the transmission seat 3, improving the connection stability between the transmission seat 3 and the lifting seat 1.

[0052] Furthermore, injection molding, also known as die molding, connects sleeve 2 and lifting seat 1 using die molding. During die molding, sleeve 2 will not deform or warp, and the overall precision can be effectively guaranteed. Sleeve 2 is made as short as possible so that the structure on both sides of lifting seat 1 is as similar as possible to the structure of sleeve 2. This ensures that the overall shrinkage speed of lifting seat 1 is more consistent during injection molding, making it less prone to deformation.

[0053] like Figure 4 As shown, this embodiment also provides a camera assembly, including a camera module 4 and a lifting bracket of any of the above embodiments. The camera module 4 includes a camera and other electronic components. The camera module 4 is installed in the mounting slot 101 of the lifting base 1. The camera and other electronic components of the camera module 4 are installed and positioned through different positioning structures of the mounting slot 101. The specific installation method of the camera module 4 is prior art and will not be described in detail here.

[0054] like Figure 5 and Figure 6As shown, this embodiment also provides an electronic device, including the aforementioned camera component. Specifically, the electronic device includes, but is not limited to, mobile phones, tablets, smartwatches, and other electronic products. The main body 5 of the electronic device is provided with a storage slot, which is located at the top of the main body 5. The camera component is slidably mounted on the main body 5 of the electronic device, thereby enabling the camera component to switch between an extended position extending out of the storage slot and a retracted position retracted into the storage slot. A drive module 6 is installed inside the main body 5. The drive module 6 includes, but is not limited to, components such as a motor, cylinder, and lead screw module. The drive module 6 is connected to the lower end of the lifting seat 1, thereby driving the lifting seat 1 and the sleeve 2 to rise and fall.

[0055] When the camera component is in the storage position, the entire camera component is located in the storage slot. The upper end of the sleeve 2 covers the opening of the storage slot, and the side of the sleeve 2 abuts against the inner wall of the storage slot to achieve a seal. Since the sleeve 2 is processed by CNC technology, the processing precision is high, so the sealing performance and dustproof performance are high, preventing dust and other objects from entering the storage slot.

[0056] When the camera assembly is in the extended position, at least part of the lifting base 1, at least part of the sleeve 2, and the camera of the camera assembly are all located outside the storage slot. Because the sleeve 2 is machined using CNC technology, the sleeve 2 has high machining precision and is not easily deformed. During the lifting process, the friction between the sleeve 2 of the lifting bracket and the inner wall of the storage slot is small, ensuring the lifting accuracy of the camera assembly.

[0057] The electronic device of this application adopts the above-mentioned camera component, and the sleeve 2 is processed by CNC technology. The sleeve 2 is used as the outer decoration of the lifting bracket extending out of the storage slot. This not only ensures the aesthetic appearance of the lifting bracket, but also reduces the friction between the lifting bracket and the inner wall of the storage slot, greatly improving the lifting accuracy and enhancing the sealing and dustproof performance of the electronic device.

[0058] The technical principles of this application have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this application and should not be construed as limiting the scope of protection of this application in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this application without inventive effort, and these embodiments will all fall within the scope of protection of this application.
