Description

Technical Field

[0001] The invention relates to a camera device, in particular to a camera device with a heating module. Background Art

[0002] In the known camera device 9, the camera device 9 has a first housing 91 and a second housing 92 combined with the first housing 91, and a receiving space is defined between the first housing 91 and the second housing 92 to receive at least one circuit board 93 in the receiving space. The first housing 91 further includes a front cover 911, a front lens 912 and a lens module 913 disposed on the first housing 91. The lens module 913 includes a plurality of lenses to realize the image capture function of the camera device 9.

[0003] In order to prevent or remove freezing / frost or moisture on the front lens 912 and the lens module 913, a heating module 94 is provided and can be arranged between the front lens 912 and the lens module 913. In order to maintain the heating module 94 in a specific position, a support member 95 is provided to support the heating module 94 in the accommodation space formed when the first shell 91 and the second shell 92 are combined; in particular, one end of the support member 95 is supported on the at least one circuit board 93, and the other end of the support member 95 is used to support the heating module 94.

[0004] In detail, the heating module 94 further has a connecting element 94C, and a free end of the connecting element 94C is configured with a first electrical connection port 94P. The at least one circuit board 93 has a second electrical connection port 93P. The electrical connection between the first electrical connection port 94P and the second electrical connection port 93P can provide the power required for heating by the heating module 94.

[0005] However, when assembling the various components of the known camera device 9, since the connecting element 94C is made of a relatively flexible wire as a whole, the first electrical connection port 94P located at the free end can swing freely to a certain extent. When connecting the first electrical connection port 94P and the second electrical connection port 93P, it is difficult to align the first electrical connection port 94P due to the swing of the first electrical connection port 94P, and it is easy to interfere with and collide with other components, requiring additional manpower for assembly, causing inconvenience in assembly and increased costs.

[0006] In view of this, the conventional camera device still needs to be improved. Summary of the invention

[0007] To solve the above problems, an object of the present invention is to provide a camera device with a heating module, which can prevent the connection unit from colliding with other components or structures during the assembly process, thereby facilitating the assembler.

[0008] The directions or their approximate terms described throughout the present invention, such as "front", "rear", "left", "right", "up (top)", "down (bottom)", "inside", "outside", "side", "end" and "axial direction", etc., are mainly with reference to the directions of the attached drawings. Each direction or its approximate terms are only used to assist in the explanation and understanding of the embodiments of the present invention, and are not used to limit the present invention.

[0009] The quantifiers “a” or “an” used in the elements and components described throughout the present invention are only for convenience of use and to provide a general meaning of the scope of the present invention; in the present invention, they should be interpreted as including one or at least one, and a single concept also includes plural cases, unless it is obvious that it means otherwise.

[0010] The similar terms such as "combination", "assembly", "assembly" and "setting" mentioned throughout the present invention mainly include the connection that can be separated without destroying the components, or the connection that makes the components inseparable, and can be selected by those with ordinary knowledge in the field according to the materials of the components to be connected or the assembly requirements.

[0011] The present invention provides a camera device with a heating module, comprising: a first shell, having a first end and a second end, and having a first channel and a second channel; the first channel connects the first end and the second end; the second channel connects from one side of the first end to one side of the second end; a plurality of lenses are arranged in the first channel; a heating module, having a heating unit and a connecting unit; the heating unit is arranged at a specific position of the plurality of lenses; the connecting unit is connected to the heating unit and is passed through the second channel; a second shell, combined with the first shell to form a accommodating space; and a circuit board, arranged in the accommodating space; wherein the connecting unit passing through the second channel is electrically connected to the circuit board.

[0012] Accordingly, the camera device with a heating module of the present invention directly supports the heating module / the heating unit through the first housing, which can save the need for additional components for support, thereby achieving the effects of improving assembly convenience and reducing the cost of manufacturing additional components. In addition, the second channel can be used exclusively for the connection unit, so that the connection unit can avoid collision with other components or structures during the assembly process, thereby facilitating assembly.

[0013] Among the plurality of lenses, there is a first lens which is farthest from the circuit board, and the heating unit is disposed between the first lens and the circuit board. Thus, through the configuration of the heating unit, the effect of avoiding or removing freezing or moisture on the plurality of lenses can be achieved.

[0014] Among the plurality of lenses, there is another second lens, the second lens is located between the first lens and the circuit board, and the heating unit is disposed between the first lens and the second lens. Thus, by disposing the heating unit between the first lens and the lens module, the effect of more efficiently avoiding or removing freezing or moisture on the first lens can be achieved.

[0015] The first housing has a first sub-housing and a second sub-housing, and the first sub-housing and the second sub-housing are each provided with at least one of the plurality of lenses. Thus, through the structural configuration of the first sub-housing and the second sub-housing, the first housing can be provided with a lens in one of the first and second sub-housings according to actual needs, thereby improving the convenience of assembly.

[0016] The connection unit has a first connection portion protruding out of the second channel, and the first connection portion is disposed on the wall of the first shell adjacent to the second end; the circuit board has a second connection portion, and the second connection portion is connected to the first connection portion. Thus, through the positional configuration of the first connection portion and the second connection portion, during the assembly process of the first shell and the second shell, the first connection portion and the second connection portion will not collide with other components or structures, thereby achieving the effect of facilitating assembly.

[0017] The first connection part is a gold finger connection port, and the second connection part is an elastic probe, so that the assembly is convenient.

[0018] The circuit board is composed of a plurality of sub-circuit boards, and the plurality of sub-circuit boards are electrically connected. Thus, by making the circuit board composed of a plurality of sub-circuit boards, the problem of increased manufacturing cost caused by using a single circuit board requiring a more precise circuit configuration can be avoided.

[0019] One of the plurality of sub-circuit boards has a light sensing element, so that the light sensing element can be used to receive and / or convert the optical information obtained by the plurality of lenses.

[0020] The light sensing element and the second connection portion are arranged on the same sub-circuit board among the plurality of sub-circuit boards. Thus, by configuring the light sensing element and the second connection portion on the same sub-circuit board, other sub-circuit boards can have more space to configure circuits or elements with other functions.

[0021] The light sensing element and the second connection part are arranged on different sub-circuit boards among the plurality of sub-circuit boards. Thus, by arranging the light sensing element and the second connection part on different sub-circuit boards, the problem of increased manufacturing cost caused by the need for more precise circuit configuration when using a single sub-circuit board can be avoided.

[0029] In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the first preferred embodiment of the present invention is specifically cited below and described in detail with reference to the accompanying drawings.

[0030] Please refer to Figures 2 to 5, which are a preferred embodiment of a camera device with a heating module of the present invention, comprising a first housing 1, a plurality of lenses 2, a heating module 3, a second housing 4 and a circuit board 5. The plurality of lenses 2 and the heating module 3 are disposed in the first housing 1, the first housing 1 and the second housing 4 are combined to define a receiving space S, and the circuit board 5 is disposed in the receiving space S.

[0031] As shown in Figures 2, 3 and 5, the first housing 1 has a first end 1a and a second end 1b, and the first end 1a and the second end 1b are opposite to each other in an axial direction. The first housing 1 has a first channel 10A (particularly extending along the axial direction) connecting the first end 1a and the second end 1b. In particular, the first channel 10A is formed by the wall of the first housing 1. Optionally, the first housing 1 also has a second channel 10B (particularly extending along the axial direction) connecting from one side of the first end 1a to one side of the second end 1b. In particular, the second channel 10B is formed by the wall of the first housing 1. Preferably, the second channel 10B and the first channel 10A are separate independent channels and are not connected to each other; however, it should be noted that in a partial implementation state, it is not excluded that the first channel 10A and the second channel 10B are partially connected. Optionally, the first shell 1 has a first sub-shell 11 and a second sub-shell 12, the first sub-shell 11 has a first sub-channel 11A, and the second sub-shell 12 has a second sub-channel 12A. When the first sub-shell 11 and the second sub-shell 12 are combined, the first sub-channel 11A is connected to the second sub-channel 12A to form the first channel 10A.

[0032] The plurality of lenses 2 are arranged in the first housing 1, in particular, in the first channel 10A. Among the plurality of lenses 2, there is a first lens 21 which is farthest from the circuit board. In particular, the first lens 21 of the plurality of lenses 2 is farthest from the second end 1b of the first housing 1. In other words, the first lens 21 is farthest from the circuit board 5. In addition, the plurality of lenses 2 further comprises a second lens (not shown), in particular, the other lenses of the plurality of lenses 2 which are different from the first lens 21 are located in a lens module LM, and the second lens is arranged in the lens module LM; that is, the second lens / the lens module LM is located between the first lens 21 and the circuit board 5. Optionally, the first sub-housing 11 and the second sub-housing 12 are each provided with at least one of the plurality of lenses; for example, the first lens 21 can be arranged in the first sub-housing 11, and the second lens / the lens module LM can be arranged in the second sub-housing 12. It should be noted that the technology of providing at least one lens (ie, at least including the second lens) in the lens module LM is understandable to those skilled in the art, and thus will not be described in detail.

[0033] The heating module 3 is disposed on the first shell 1. The heating module 3 has a heating unit 31 and a connecting unit 32. The heating unit 31 can be used to generate heat energy to avoid or remove the situation where the multiple lenses 2 have freezing or moisture. The heating unit 31 is located at a specific position of the multiple lenses 2, and in particular, it can surround one or more of the multiple lenses 2 at the specific position. Optionally, the heating unit 31 is disposed between the first lens 21 and the circuit board 5. Preferably, the heating unit 31 is disposed between the first lens 21 and the second lens / the lens module LM; in this way, the situation where the first lens has freezing or moisture can be more efficiently avoided or removed. Optionally, the heating unit 31 forms a ring shape.

[0034] It should be particularly noted that, in the known technology shown in FIG. 1 , in order to allow the heating module 93 to be disposed at the target position of the lens module 913 in the accommodation space formed by the first shell 91 and the second shell 92, the support member 95 must be additionally provided to support the heating module 93 to be positioned at the target position. In particular, in order to set the support member 95, the at least one circuit board 93 may need to be provided with a corresponding matching structure or increase the strength for the support member 95 to abut against. Therefore, in the known camera device 9, an additional support member 95 needs to be provided to support the heating module 94, so that the overall components of the known camera device 9 are more, resulting in a higher complexity of assembly. In this regard, in an optional embodiment of the present invention, the heating module 3 can be assembled from the first end 1a side of the first shell 1, and the heating module 3 / the heating unit 31 can be directly supported by the first shell 1, so as to eliminate the need for additional supporting elements (support members 95) as required in the conventional technology (as shown in FIG. 1), thereby improving assembly convenience and reducing the cost of manufacturing additional elements.

[0035] The connecting unit 32 is connected to the heating unit 31 and can be used to transmit the power required by the heating unit 31 when generating heat energy, and the connecting unit 32 is arranged in the second channel 10B. In particular, the connecting unit 32 extends from the heating unit 31 (along an axial direction). In this way, the second channel 10B can be used exclusively for the setting of the connecting unit 32, so that the connecting unit 32 is configured in its entirety or in large part in the second channel 10B, for example, in particular, only the end of the connecting unit 32 (one end is connected to the heating unit 31 and / or one end (for example, the first connecting portion 32P described later) is connected to the second connecting portion 5P of the circuit board 5 described later) is exposed outside the second channel 10B, so that the connecting unit 32 can avoid collision with other components or structures during the assembly process.

[0036] Optionally, the connection unit 32 has a first connection portion 32P. In particular, the first connection portion 32P of the connection unit 32 protrudes out of the second channel 10B and is disposed on the wall of the first shell 1 adjacent to the second end 1b. In particular, the first connection portion 32P can be combined with the wall of the first shell 1 adjacent to the second end 1b by bonding or snapping, and is not limited to the above-mentioned combination method. In one example, the connection unit 32 can be a flexible circuit board, and the first connection portion 32P can be a gold finger connection port; in other examples, the first connection portion 32P can also be an electrical slot; however, the present invention is not limited to such examples.

[0037] As shown in FIGS. 2, 4 and 5, the second housing 4 is combined with the first housing 1 to define a receiving space S (as shown in FIG. 4). In detail, at least one of the first housing 1 and the second housing 4 has a corresponding recessed portion C, and when the first housing 1 and the second housing 4 are combined, the receiving space S is formed by the corresponding recessed portion C. In the illustrated example of the present invention, although the second housing 4 is illustrated as having the recessed portion C, the configuration of the recessed portion C can be changed according to needs and is not limited to the drawings disclosed in the present invention.

[0038] The circuit board 5 is disposed in the accommodation space S, and the connection unit 32 is electrically connected to the circuit board 5 to transmit the power from the circuit board 5 from the connection unit 32 to the heating unit 31. In detail, the circuit board 5 has a second connection portion 5P and may also have a light sensing element 5S; in particular, the second connection portion 5P and the light sensing element 5S are disposed on the circuit board 5 facing the second end 1b. The second connection portion 5P is connected to the first connection portion 32P, in particular, electrically connected. The light sensing element 5S is used to receive optical information obtained by the plurality of lenses 2. In one example, the second connection portion 5P may be a probe, preferably a probe with elasticity, such as a spring probe (Pogo Pin), so as to better match the configuration of the first connection portion 32P as a gold finger connection port; in other examples, the second connection portion 5P may also be a pin header, so as to better match the configuration of the first connection portion 32P as an electrical slot; however, the present invention is not limited to these examples.

[0039] It should be noted that, in one example, before the first shell 1 and the second shell 4 are assembled, the first connecting portion 32P is disposed on the wall of the first shell 1 adjacent to the second end 1b, so that a first specific positional relationship exists between the first connecting portion 32P and the first shell 1; and the circuit board 5 can be first disposed in the recessed portion C of the second shell 4, so that a second specific positional relationship exists between the second connecting portion 5P and the second shell 4; and by configuring the first specific positional relationship and the second specific positional relationship, when the first shell 1 and the second shell 4 are assembled, the first connecting portion 32P and the second connecting portion 5P are aligned, and in the process from separation to combination of the first shell 1 and the second shell 4, the first connecting portion 32P can only contact the second connecting portion 5P, and the second connecting portion 5P can only contact the first connecting portion 32P. In other words, during the process of combining the first shell 1 and the second shell, the first connecting portion 32P and the second connecting portion 5P will not collide with other components or structures, thereby achieving the effect of convenient assembly.

[0040] Please refer to Figures 6 and 7, which are the second preferred embodiment of the camera device with a heating module of the present invention. This embodiment is substantially the same as the first preferred embodiment, and the main difference is that in the second preferred embodiment, the circuit board 5 can be composed of a plurality of sub-circuit boards 51, and the plurality of sub-circuit boards 51 are electrically connected (including direct electrical connection or indirect electrical connection). In one example, the number of the plurality of sub-circuit boards 51 is two, and the second connection portion 5P and the light sensing element 5S are arranged on different sub-circuit boards 51; in particular, the light sensing element 5S is arranged on a sub-circuit board 51 close to the lens module LM, and the second connection portion 5P is arranged on another sub-circuit board 5 far away from the lens module LM; in other examples, the second connection portion 5P and the light sensing element 5S can be arranged on the same sub-circuit board 51. Therefore, it should be noted that the number of the plurality of sub-circuit boards 51 and whether the second connection portion 5P and the light sensing element 5S are arranged on the same sub-circuit board 51 are not limited to the diagram disclosed in the present invention.

[0041] In summary, the camera device with a heating module of the present invention directly supports the heating module / heating unit through the first shell, which can save the need for additional components for support, thereby improving the convenience of assembly and reducing the cost of manufacturing additional components. In addition, the second channel can be used exclusively for the connection unit to be set, so that the connection unit can avoid collision with other components or structures during the assembly process, and the assembly can be facilitated. In addition, by setting the heating unit between the first lens and the second lens / lens module, the situation of freezing or moisture on the first lens can be more efficiently avoided or removed. In addition, by making the first and second connecting parts specially configured in position (the first and second specific position relationship), the first and second connecting parts can be assembled in the process of the camera device with a heating module of the present invention. The first and second connecting parts will not collide with other components or structures, and the assembly can be facilitated. In addition, the configuration of the first and second connecting parts as a gold finger connection port and a probe with elasticity respectively can facilitate assembly.

[0042] Although the present invention has been disclosed using the above preferred embodiments, they are not intended to limit the present invention. Any person skilled in the art may make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention. The scope of protection of the present invention shall be determined by the scope of the attached patent application.
