現在市面上販售的智慧型手機皆具有鏡頭模組，其可供使用者隨時拍攝照片或影片，而對使用者帶來極大的方便性。一般的鏡頭模組是設置在電路板上，鏡頭模組具有鏡頭座、鏡片和感光元件。鏡頭座具有座體和管體，座體的底部連接電路板，管體連接座體。鏡片設於管體之內。感光元件位於座體內部並連接電路板，且感光元件和鏡片之間具有一定焦 距離。在攝影時，鏡片會將光線傳送到定焦距離上的感光元件，而讓光線清楚得在感光元件上成像。 Smartphones currently on the market all have a lens module, which allows users to take photos or videos at any time, which brings great convenience to users.

Through the insert molding process, the first fixing member 20 and the two second fixing members 30 having the detailed fixing structure can be combined with the first fixing slot 12 and the two second fixing slots 13 respectively. In this way, the combined heat-resistant drift base 10, the first card holder 20, and the two second card holders 30 have a function of preventing heat drift, and also have a detailed locking structure to further interact with the lens barrel 40 and the circuit board. 110 combined with each other.
如圖1至圖4所示，當使用者頻繁得操作電子裝置100，使得電子裝置100之電路板110以及感光元件60散發熱能時，熱能會先傳導給防熱飄移座體10。由於防熱飄移座體10是由防止熱膨脹、熱性線膨脹係數趨近於零的材質所製成，因此防熱飄移座體10幾乎 不發生任何體積變化。另外，防熱飄移座體10、第一卡固件20和二個第二卡固件30是獨立的元件，防熱飄移座體10、第一卡固件20和二個第二卡固件30是靠著各自的卡固結構而互相結合；而且防熱飄移座體10之第一卡固槽12以及二個第二卡固槽13、第一卡固件20之螺紋部21和卡固環22，和二個第二卡固件30之卡固塊31的表面並非完全光滑，該些元件的表面上仍會有極細微的凹凸不平的空隙；因此，當防熱飄移座體10之第一卡固槽12以及二個第二卡固槽13、第一卡固件20之螺紋部21和卡固環22，和二個第二卡固件30之卡固塊31互相結合時，該些元件的凹凸不平的表面會彼此貼合並讓少許空氣位於凹凸不平的空隙裡，而該些空氣會有效阻礙熱量傳遞；也就是說，傳導給防熱飄移座體10的熱能會難以進一步得傳遞給第一卡固件20、二個第二卡固件30和鏡筒40。因此，即使第一卡固件20、二個第二卡固件30和鏡筒40並不是以防止熱膨脹得材質所製成，第一卡固件20、二個第二卡固件30和鏡筒40也不會受到電路板110和感光元件60散發熱能影響。因此，當電路板110和感光元件60散發熱能時，防熱飄移座體10、第一卡固件20、二個第二卡固件30和鏡筒40都不會受到熱能影 響，也不會改變體積，如此一來即可防止受熱變形而造成焦距飄移的熱飄移問題。 As shown in FIG. 1 to FIG. 4, when a user frequently operates the electronic device 100 so that the circuit board 110 and the photosensitive element 60 of the electronic device 100 dissipate heat energy, the heat energy is first transmitted to the heat-resistant drift base 10. Since the thermal drift prevention base 10 is made of a material that prevents thermal expansion and the thermal linear expansion coefficient approaches zero, the thermal drift prevention base 10 is almost No volume change occurred. In addition, the heat-resistant drift base 10, the first card holder 20, and the two second card holders 30 are independent components, and the heat-resistant drift base 10, the first card holder 20, and the two second card holders 30 are against each other. The fastening structure is combined with each other; moreover, the first retaining groove 12 and two second retaining grooves 13 of the heat-resistant drift base 10, the threaded portion 21 and the retaining ring 22 of the first retaining member 20, and two second retaining grooves 22 The surface of the fixing block 31 of the fixing member 30 is not completely smooth, and there will still be extremely fine uneven spaces on the surface of these components; therefore, when the first fixing groove 12 and the second When the two fixing grooves 13, the threaded portion 21 and the fixing ring 22 of the first fixing member 20 and the fixing blocks 31 of the two second fixing members 30 are combined with each other, the uneven surfaces of these components will be attached to each other. Let a little air be in the uneven space, and the air will effectively hinder the heat transfer; that is, the heat energy transmitted to the heat-resistant drift base 10 will be difficult to further transfer to the first card holder 20 and the two second cards. Firmware 30 and lens barrel 40. Therefore, even if the first card holder 20, the two second card holders 30, and the lens barrel 40 are not made of a material that prevents thermal expansion, the first card holder 20, the two second card holders 30, and the lens barrel 40 are not made. It is affected by the heat generated by the circuit board 110 and the photosensitive element 60. Therefore, when the circuit board 110 and the photosensitive element 60 dissipate heat, the thermal drift prevention base 10, the first fixing member 20, the two second fixing members 30, and the lens barrel 40 are not affected by the thermal energy. It will not change the volume, so that it can prevent the thermal drift problem caused by the focal length drift caused by thermal deformation.
藉由本發明之電子裝置100及其防熱飄移鏡頭模組1之結構，可防止受熱變形而造成焦距飄移的熱飄移問題，以便使用者安心得拍攝出清晰的照片或影片。 With the structure of the electronic device 100 and the heat-resistant drift lens module 1 of the present invention, the thermal drift problem caused by the focal length drift caused by thermal deformation can be prevented, so that users can take clear pictures or videos with peace of mind.
需注意的是，上述僅為實施例，而非限制於實施例。譬如此不脫離本發明基本架構者，皆應為本專利所主張之權利範圍，而應以專利申請範圍為準。 It should be noted that the above are merely examples, and are not limited to the examples. For example, those who do not depart from the basic structure of the present invention should be the scope of the rights claimed by the patent, and the scope of the patent application shall prevail.
