Description

Technical Field

[0001] The utility model relates to the technical field of cameras, in particular to a combined camera. Background Art

[0002] A camera is a device that converts optical image signals into electrical signals for storage or transmission. Traditional cameras adopt an independent integrated design, which can only be used in one camera scene or can only realize one camera function. Therefore, it cannot meet the application of different camera scenes or different camera functions.

[0003] In order to increase the camera function of the camera, a combined camera is designed in the related art. The combined camera is a new type of camera that can replace functional accessories according to the user's usage scenario. Specifically, the combined camera includes a camera body and at least two functional accessories applied to different camera scenes. By replacing different types of functional accessories connected to the camera body, the camera can be applied to a variety of different scenes. For example, when the functional accessories are replaced with a network port module, the camera scene can be a security monitoring scene; or, when the functional accessories are replaced with a handle module, the camera scene can be an outdoor sports shooting scene; or, when the functional accessories are replaced with a live broadcast module, the camera scene can be a live broadcast with goods scene. Therefore, by replacing the functional accessories connected to the camera body, the use scenarios of the camera are increased.

[0004] However, after replacing the corresponding functional accessories, the user needs to manually configure the camera body to match the working mode of the currently connected functional accessories according to the type of the connected functional accessories. This operation requires manual setting by the user, which increases the difficulty of use for the user. Therefore, the operation of replacing functional accessories of the combined camera in the related art is relatively difficult. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The technical solutions disclosed in various embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 7 As shown, an embodiment of the utility model discloses a combined camera, which includes a camera body 100 and at least two functional accessories 200 applied to different camera scenes.

[0026] The camera body 100 has a camera function, and the camera body 100 includes but is not limited to components such as a camera, an image sensor chip, a display screen, a circuit board, and a housing. The camera body 100 has at least two different camera modes. The camera mode here refers to the specific working parameter configuration of components such as the camera, the display screen, and the image sensor chip of the camera body 100 in the camera scene. The functional accessories 200 are used in conjunction with the camera body 100, and each camera mode of the camera body 100 is adapted to the camera scene corresponding to the corresponding functional accessories 200.

[0027] The functional accessory 200 can expand different camera scenes for the camera body 100. That is, a simple camera body 100 can only be used in one camera scene. For example, a simple camera body 100 can only realize video shooting. The functional accessory 200 can expand the use scene of the camera body 100. For example, when the functional accessory 200 is a network port module, the functional accessory 200 expands the network port connection function for the camera body 100, so that the camera body 100 can be connected to the external monitoring equipment in parallel, so that the camera body 100 can be applied to the comfort monitoring scene. For another example, when the functional accessory 200 is a handle module, the user can move the camera body 100 through the handle module, so that the camera body 100 can be applied to the outdoor sports video shooting scene. Of course, the functional accessory 200 can also be a live broadcast accessory, a game accessory, etc., and the corresponding camera body 100 can be applied to the live broadcast scene with goods and the game scene. This application does not limit the number and type of functional accessories 200, as long as the functional accessories 200 that can match the camera body 100 belong to the scope of protection of this application.

[0028] In different camera scenes, the current, voltage, signal and other configuration parameters of the camera, display screen, image sensor chip and other components of the camera body 100 are different. Therefore, in different camera scenes, it is necessary to configure parameters that match the camera scene. The camera body 100 stores parameter configuration methods required for multiple camera scenes. The parameter configuration methods mentioned here can be understood as the camera modes mentioned above. In different camera scenes, users can call different parameter configuration methods, that is, call different camera modes.

[0029] For example, when the combination camera is in a security monitoring scene, the camera mode of the camera body 100 is switched to a mode that matches the security monitoring scene, that is, the specific working parameter configurations of the camera, display, image sensor chip and other components of the camera body 100 match the security monitoring scene; when the combination camera is in an outdoor sports video shooting scene, the camera mode of the camera body 100 is switched to a mode that matches the outdoor sports video shooting scene.

[0030] In the related art, when a functional accessory 200 is assembled on the camera body 100, the camera body 100 cannot identify the specific type of the camera body 100, so the user needs to manually call the corresponding camera mode according to the type of the installed functional accessory 200. The specific operation steps here are that after the user connects the current functional accessory 200 to the camera body 100, the user manually calls the corresponding camera mode of the camera body 100, and the current camera mode is adapted to the camera scene applied by the functional accessory 200. After the camera mode is switched, the camera body 100 configures corresponding parameters for each component of the camera body 100 according to the switched mode.

[0031] However, each time the functional accessory 200 is replaced, the camera mode needs to be manually configured, so the operation of replacing the functional accessory 200 of the combined camera in the related art is relatively difficult.

[0032] In the combined camera disclosed in the present application, the camera body 100 has a first identification part 101 and a controller, and the functional accessory 200 has a second identification part 201. The electrical connection structure of the second identification part 201 and the first identification part 101 of different functional accessories 200 is different, and different electrical connection mechanisms form different signal parameters. The different functional accessories 200 here refer to different camera scenes used, that is, the types of functional accessories 200 are different. At this time, each different type of functional accessories 200 can generate a corresponding signal parameter. Therefore, each signal parameter can correspond to a type of functional accessory 200. Therefore, in the combined camera disclosed in the present application, each signal parameter is used to enable the camera body 100 to identify a corresponding type of functional accessory 200. The controller is used to switch the camera mode adapted to the functional accessory 200 according to the identified functional accessory 200.

[0033] During the specific operation, at least two functional accessories 200 applied to different camera scenes can be respectively a network port module, a handle module and a live broadcast accessory. The second identification part 201 on the network port module is electrically connected to the first identification part 101 to form a first signal parameter; the second identification part 201 on the handle module is electrically connected to the first identification part 101 to form a second signal parameter; the second identification part 201 on the live broadcast accessory is electrically connected to the first identification part 101 to form a third signal parameter. The first signal parameter, the second signal parameter and the third signal parameter are all different. When the functional accessory 200 is installed on the camera body 100, the camera body 100 will read the signal parameter. When the signal parameter read is the first signal parameter, the camera body 100 can recognize that the functional accessory 200 it is equipped with is a network port module. Similarly, when the signal parameter read is the second signal parameter, the camera body 100 can recognize that the functional accessory 200 it is equipped with is a handle module. When the signal parameter read is the third signal parameter, the camera body 100 can recognize that the functional accessory 200 it is equipped with is a live broadcast accessory. The controller switches to a camera mode adapted to the current functional accessory 200 according to the identified functional accessory 200 .

[0034] In the embodiment disclosed in the present application, the camera body 100 can identify the type of the currently connected functional accessory 200 through the signal parameters formed by the electrical connection between the second identification unit 201 and the first identification unit 101. Therefore, when the camera body 100 identifies the type of the functional accessory 200, the controller of the camera body 100 can switch to a corresponding camera mode according to the type of the functional accessory 200. Therefore, the combined camera disclosed in the present application can self-identify the functional accessories 200 used in different camera scenes, thereby eliminating the need for the user to manually configure the camera mode, thereby reducing the user's usage difficulty and simplifying the user's operation method. Therefore, the technical solution disclosed in the present application reduces the operational difficulty of replacing the functional accessories 200 of the combined camera.

[0035] In the embodiments disclosed in the present application, the signal parameters formed by the second identification part 201 and the first identification part 101 of different functional accessories 200 can be stored as comparison values ​​in the storage device of the camera body 100. The current signal parameters formed by the functional accessories 200 currently installed on the camera body 100 and the first identification part 101 are compared with the comparison values ​​in the storage device. After the current signal parameters match one of the comparison values, the type of the current functional accessory 200 can be identified. The current functional accessory 200 here refers to a functional accessory 200 connected to the camera body 100. The above-mentioned controller can be a SoC (System on Chip). Of course, the controller can also be other structures, which are not limited in this article.

[0036] In an optional solution, the first identification unit 101 may include at least one first identification pin 101a, at least one first resistor 101b and a hardware identifier 101c, at least one first identification pin 101a is connected to at least one first resistor 101b in a one-to-one correspondence; and the resistance values ​​of all first resistors 101b are the same. At this time, the level states of all first resistors 101b on the camera body 100 are the same. Optionally, the first resistor 101b is a pull-up resistor, and at this time, all first identification pins 101a on the camera body 100 are weakly pulled up, and the weak pull-up states of all first identification pins 101a are the same. It should be noted here that setting the first resistor 101b with the same resistance value is to ensure that the current or voltage value of all first identification pins 101a is the same. Therefore, it is ensured that all first identification pins 101a are in the same level state.

[0037] The second identification part 201 includes at least one second identification pin 201a and at least one second resistor 201b, and at least one second identification pin 201a is connected to at least one second resistor 201b in a one-to-one correspondence. The resistance value of at least one second resistor 201b between different functional accessories 200 is different. Each first identification pin 101a is electrically connected to a corresponding second identification pin 201a. Since the resistance value of at least one second resistor 201b between different functional accessories 200 is different, it is explained that the current or voltage value of the second identification pin 201a corresponding to the second resistor 201b with different resistance values ​​between different functional accessories 200 is different. When the first identification pin 101a is electrically connected to the second identification pin 201a with different current or voltage, the level state of the first identification pin 101a will change. Therefore, the present application can identify different types of functional accessories 200 by identifying the level state of the first identification pin 101a. The electrical connection structure in the above text is the first identification pin 101a, the second identification pin 201a, the first resistor 101b and the second resistor 201b. What is different here is the resistance value of at least one second resistor 201 b.

[0038] In the specific operation process, the hardware identifier 101c is associated with all the first identification pins 101a, and the hardware identifier 101c is used to obtain the level state of all the first identification pins 101a to form signal parameters. Each set of signal parameters is a level state array corresponding to a type of functional accessory 200. The hardware identifier 101c here is associated with all the first identification pins 101a, so the level state of the hardware identifier 101c is the same as the level state of the first identification pin 101a. Therefore, when the level of the first identification pin 101a changes, the level state of the hardware identifier 101c also changes, and the level state changes between the two are the same, that is, when the first identification pin 101a is high, the hardware identifier 101c is also high, so the level state array output by the hardware identifier 101c is [1]. When the first identification pin 101a is low, the hardware identifier 101c is also low, so the level state array output by the hardware identifier 101c is [0].

[0039] In a specific solution, the first identification pin 101a is electrically connected to the first resistor 101b, and at this time, the first identification pin 101a is weakly pulled up, so the first identification pin 101a is in a weak pull-up state. At least two functional accessories 200 applied to different camera scenes are functional accessory No. 1 and functional accessory No. 2, respectively. The number of first identification pins 101a can be one, and the number of corresponding second identification pins 201a can also be one. At this time, the resistance value of the second resistor 201b of functional accessory No. 1 is greater than the resistance value of the second resistor 201b of functional accessory No. 2, so the second identification pin 201a of functional accessory No. 2 is in a strong pull-down state, and the second identification pin 201a of functional accessory No. 1 is in a weak pull-down state.

[0040] When the No. 1 functional accessory is connected to the camera body 100, since the second identification pin 201a of the No. 1 functional accessory is in a weak pull-down state and the first identification pin 101a is in a weak pull-up state, the current or voltage of the first identification pin 101a is greater than the current or voltage of the second identification pin 201a of the No. 1 functional accessory, so that the first identification pin 101a displays a high level. At this time, the hardware identifier 101c outputs [1]. Therefore, [1] corresponds to the No. 1 functional accessory. When the No. 2 functional accessory 200 is connected to the camera body 100, since the second identification pin 201a of the No. 2 functional accessory is in a strong pull-down state and the first identification pin 101a is in a weak pull-up state, the current or voltage of the first identification pin 101a is less than the current or voltage of the second identification pin 201a of the No. 2 functional accessory, so that the first identification pin 101a displays a low level. At this time, the hardware identifier 101c outputs the level state array [0]. Therefore, the level state array [0] corresponds to the No. 2 functional accessory. That is to say, when the level status array output by the hardware identifier 101c is [1], the functional accessory 200 currently connected to the camera body 100 is functional accessory No. 1; when the level status array output by the hardware identifier 101c is [0], the functional accessory 200 currently connected to the camera body 100 is functional accessory No. 2.

[0041] In this solution, different functional accessories 200 can change the level state of the first identification pin 101a to different changes, so the identification function of the corresponding functional accessory 200 can be achieved by obtaining the level state change of the first identification pin 101a.

[0042] In addition, this solution can realize the identification function of the functional accessory 200 by identifying the level state of the pin, thereby reducing the manufacturing cost and difficulty of the combined camera. In addition, the level state of the identification pin responds quickly, so that the camera body 100 can quickly identify the type of the functional accessory 200, thereby improving the efficiency of accessory identification.

[0043] In the above embodiment, two types of functional accessories 200 can be identified when there is only one first identification pin 101a. Figure 1 As shown, when the number of the first identification pin 101a and the second identification pin 201a is two, four types of functional accessories 200 can be identified. At this time, the hardware identifier 101c has two character units, namely HWID-IO1 and HWID-IO2. HWID-IO1 and HWID-IO2 are respectively connected to a first identification pin 101a, so the hardware identifier 101c can output four groups of level state arrays, namely: [0, 0], [0, 1], [1, 0] and [1, 1]. These four groups of level state arrays correspond to four types of functional accessories 200. As shown in FIG. Figure 1 As shown, the resistance values ​​of the two first resistors 101b of the camera body 100 are the same, so before the functional accessory 200 is inserted, the level states of all the first identification pins 101a of the camera body 100 are in the same state. By changing the resistance value of the second resistor 201b between different functional accessories 200, the resistance value of at least one second resistor 201b between different functional accessories 200 is different.

[0044] In a specific solution, the resistance of the first resistor 101b is 4.7Kohm, the resistance of r1 of functional accessory No. 1 is 1Kohm, and r2 is 1Kohm. At this time, the obtained level state array is [0, 0]. The resistance of r1 of functional accessory No. 2 is 1Kohm, and r2 is 10Kohm. At this time, the obtained level state array is [0, 1]. The resistance of r1 of functional accessory No. 3 is 10Kohm, and r2 is 1Kohm. At this time, the obtained level state array is [1, 0]. The resistance of r1 of functional accessory No. 4 is 10Kohm, and r2 is 10Kohm. At this time, the obtained level state array is [1, 1].

[0045] In another optional embodiment, if Figure 2 As shown, the number of the first identification pin 101a and the number of the second identification pin 201a are both three. At this time, the three pins can realize 8 different level change modes, so the three pins can identify more functional accessories 200. This solution can not only realize the identification of more functional accessories 200, but also ensure that the number of pins is small, thereby simplifying the circuit structure.

[0046] Specifically, the hardware identifier 101c has three character units, namely HWID-IO1, HWID-IO2 and HWID-IO3. HWID-IO1, HWID-IO2 and HWID-IO3 are respectively connected to a first identification pin 101a, so the hardware identifier 101c can output eight groups of level state arrays, namely: [0, 0, 0], [0, 0, 1], [0, 1, 0], [0, 1, 1], [1, 0, 0], [1, 0, 1], [1, 1, 0] and [1, 1, 1]. These eight groups of level state arrays correspond to eight different types of functional accessories 200.

[0047] In a specific solution, the resistance of the first resistor 101b is 4.7Kohm. At this time, the resistance of r1 of functional accessory No. 1 is 1Kohm, r2 is 1Kohm, and r3 is 1Kohm. At this time, the obtained level state array is [0, 0, 0]. The resistance of r1 of functional accessory No. 2 is 1Kohm, r2 is 1Kohm, and r3 is 10Kohm. At this time, the obtained level state array is [0, 0, 1]. The resistance of r1 of functional accessory No. 3 is 1Kohm, r2 is 10Kohm, and r3 is 1Kohm. At this time, the obtained level state array is [0, 1, 0]. The resistance of r1 of functional accessory No. 4 is 10Kohm, r2 and r3 are both 10Kohm, and at this time, the obtained level state array is [0, 1, 1]. The resistance of r1 of functional accessory No. 5 is 10Kohm, r2 and r3 are both 1Kohm, and at this time, the obtained level state array is [1, 0, 0]. The resistance values ​​of r1 and r3 of function accessory No. 6 are both 10Kohm, and r2 is 1Kohm. At this time, the obtained level state array is [1, 0, 1]. The resistance values ​​of r1 and r2 of function accessory No. 7 are both 10Kohm, and r3 is 1Kohm. At this time, the obtained level state array is [1, 1, 0]. The resistance values ​​of r1, r2 and r3 of function accessory No. 8 are all 10Kohm. At this time, the obtained level state array is [1, 1, 1].

[0048] In another optional embodiment, the first identification part 101 may include a plurality of first communication contacts 110, and the second identification part 201 may include a plurality of second communication contacts 210. The plurality of second communication contacts 210 of each functional accessory 200 may be electrically connected to the plurality of first communication contacts 110 in a one-to-one correspondence. Signals are transmitted between the camera body 100 and the functional accessory 200 via the first communication contacts 110 and the second communication contacts 210, thereby achieving communication between the camera body 100 and the functional accessory 200. The number of second communication contacts 210 on at least one functional accessory 200 is less than the number of first communication contacts 110, and the number of second communication contacts 210 between different types of functional accessories 200 is different. The above-mentioned signal parameter is the number of communications between the plurality of second communication contacts 210 and the plurality of first communication contacts 110.

[0049] For example, two functional accessories 200 applied to different camera scenes are functional accessories No. 1 and functional accessories No. 2. The number of second communication contacts 210 on functional accessory No. 1 is the same as the number of first communication contacts 110 on the camera body 100. Therefore, when functional accessory No. 1 is connected to the camera body 100, each second communication contact 210 on functional accessory No. 1 can be electrically connected to a corresponding first communication contact 110. In other words, all first communication contacts 110 on the camera body 100 are occupied and are in a communication state. The number of second communication contacts 210 on functional accessory No. 2 is less than the number of first communication contacts 110 on the camera body 100. Therefore, when functional accessory No. 2 is connected to the camera body 100, the upper part of the first communication contacts 110 on the camera body 100 is not occupied, and this part of the first communication contacts 110 does not communicate. Therefore, when the camera body 100 in this scheme is connected to different functional accessories 200, the number of first communication contacts 110 of the camera body 100 in a communication state is different. Therefore, by identifying the number of first communication contacts 110 in the communication state, the type of functional accessory 200 can be identified. Here, since the number of first communication contacts 110 in the communication state is different, the signals after different types of functional accessories 200 and the camera body 100 are connected are different, thereby realizing the identification of different functional accessories 200. The above-mentioned electrical connection structure is a plurality of first communication contacts 110 and a plurality of second communication contacts 210, and the difference is the number of communication contacts.

[0050] In this solution, the functional accessory 200 is identified by using the communication contacts between the camera body 100 and the functional accessory 200 , which can simplify the structure of the combined camera, thereby making it easier for the camera body 100 to expand more functional accessories 200 .

[0051] In another optional embodiment, the first identification part 101 may include a plurality of first communication contacts 110, and the second identification part 201 may include a plurality of second communication contacts 210. The plurality of second communication contacts 210 of each functional accessory 200 may be electrically connected to the plurality of first communication contacts 110 in a one-to-one correspondence, and the number of second communication contacts 210 on each functional accessory 200 is less than or equal to the number of first communication contacts 110; the signal parameter is the communication sequence number between the plurality of second communication contacts 210 and the plurality of first communication contacts 110. Here, it means that between functional accessories 200 of different types, the connection sequence or connection position of the plurality of second contacts and the plurality of first communication contacts 110 is different. The difference between this scheme and the above scheme is that when the number of functional accessories 200 of different types is the same, they can be identified by the communication sequence number between the communication contacts. The signals after the functional accessories 200 of different types and the camera body 100 are connected are different, thereby realizing the identification of different functional accessories 200. The above-mentioned electrical connection structure is a plurality of first communication contacts 110 and a plurality of second communication contacts 210, and the difference lies in the connection sequence numbers of the communication contacts.

[0052] like Figure 4 , Figure 5 and Figure 7 As shown, the camera body 100 has 8 first communication contacts 110, which are respectively first communication contact No. 1 111, first communication contact No. 2 112, first communication power-on No. 3 113, first communication contact No. 4 114, first communication contact No. 5 115, first communication contact No. 6 116, first communication contact No. 7 117 and first communication contact No. 8 118. Functional accessory No. 1 has 7 second communication contacts 210, which are divided into second communication contact No. 1 211, second communication contact No. 2 212, second communication power-on No. 3 213, second communication contact No. 4 214, second communication contact No. 5 215, second communication contact No. 6 216 and second communication contact No. 7 217.

[0053] At this time, when the functional accessory No. 1 is connected to the camera body 100, the first communication contacts 110 No. 1 to 7 are connected to the second communication contacts 210 No. 1 to 7 in a one-to-one correspondence. Figure 4As shown, functional accessory No. 2 also has 7 second communication contacts 210. At this time, when functional accessory No. 2 is connected to the camera body 100, the first communication contacts 110 from 1 to 6 are connected to the second communication contacts from 1 to 6 in a one-to-one correspondence, and the second communication contact No. 7 217 is connected to the first communication contact No. 8 118. At this time, when the camera body 100 is connected to functional accessory No. 1, the first communication contacts No. 1 to 7 of the camera body 100 are in a communication state. When the camera body 100 is connected to functional accessory No. 2, the first communication contacts No. 1 to 6 and No. 8 of the camera body 100 are in a communication state. Therefore, the communication serial numbers of functional accessory No. 1 and functional accessory No. 2 are different.

[0054] This solution has the same effect as the above solution, so it will not be described in detail in this article.

[0055] In order to further improve the reliability of combined camera recognition, in another optional embodiment, a plurality of first communication contacts 110 are provided on the camera body 100, and some of the plurality of first communication contacts 110 are first identification pins 101a. A plurality of second communication contacts 210 are provided on the functional accessory 200, and some of the plurality of second communication contacts 210 are second identification pins 201a. The signal parameters may include pre-identification parameters and auxiliary identification parameters, and the pre-identification parameters are level state arrays; the plurality of second communication contacts 210 of each functional accessory 200 may be electrically connected to the plurality of first communication contacts 110 in a one-to-one correspondence, the number of second communication contacts 210 on at least one functional accessory 200 is less than the number of first communication contacts 110, and the number of second communication contacts 210 between different types of functional accessories 200 is different. The auxiliary identification parameter is the number of communications between the plurality of second communication contacts 210 and the plurality of first communication contacts 110.

[0056] In this solution, when a functional accessory 200 is connected to the camera body 100, it is first pre-identified through the level state array and then re-confirmed through the corresponding communication signal, thereby improving the reliability of the combined camera recognition and avoiding misidentification.

[0057] In addition, some of the communication contacts are used as identification pins, thereby further simplifying the circuit structure of the combined camera.

[0058] In the above scheme, since the response rate of communication signal recognition is slow, the corresponding functional accessory 200 can only be recognized after all communication signals are completed. Therefore, the above scheme combines the level recognition scheme with the communication recognition scheme, and the level recognition method performs pre-recognition to improve the recognition response rate. Communication recognition performs auxiliary judgment recognition to improve the accuracy and reliability of recognition.

[0059] In another embodiment, a plurality of first communication contacts 110 are provided on the camera body 100, and some of the plurality of first communication contacts 110 may be first identification pins 101a. A plurality of second communication contacts 210 may be provided on the functional accessory 200, and some of the plurality of second communication contacts 210 may be second identification pins 201a. The signal parameters may include pre-identification parameters and auxiliary identification parameters, and the pre-identification parameters may be a level state array; the number of second communication contacts 210 on each functional accessory 200 is less than or equal to the number of first communication contacts 110, and the auxiliary identification parameters are the communication sequence numbers between the plurality of second communication contacts 210 and the plurality of first communication contacts 110.

[0060] This solution has the same effect as the above solution, so it will not be described in detail in this article.

[0061] In another optional embodiment, the number of the first communication contacts 110 on the camera body 100 may be eight. In this solution, the eight communication contacts can not only meet the communication needs of the camera body 100, but also can combine multiple different types of identification methods, thereby reserving more expansion space to facilitate the addition of more different types of functional accessories 200.

[0062] In another optional solution, the camera body 100 may be provided with a first connection positioning portion 120, and each functional accessory 200 may be provided with a second connection positioning portion 220. The camera body 100 and each functional accessory 200 may be positioned and connected through the first connection positioning portion 120 and the second connection positioning portion 220. This solution can not only ensure good contact between the camera body 100 and the functional accessory 200, but also play a role in positioning and foolproofing, so as to avoid the risk of the camera body 100 and the functional accessory 200 being assembled in the reverse direction.

[0063] Specifically, one of the first connection positioning portion 120 and the second connection positioning portion 220 can be a buckle, and the other can be a slot, and the buckle and the slot can be snap-fitted. In this solution, the first connection positioning portion 120 and the second connection positioning portion 220 have simple structures, thereby reducing the manufacturing cost of the combined camera.

[0064] The first connection positioning portion 120 and the second positioning connection portion in the present application are not limited to the above-mentioned structure, and may also be a magnetic structure or a threaded structure, which is not limited in this article.

[0065] The above embodiments of the present invention focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0066] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
