Description

Technical Field

[0001] This application belongs to the technical field of electronic products, and particularly relates to a detection device, an electronic device, and a detection method. Background Art

[0002] With the continuous development of electronic devices, more and more detection devices are installed in electronic devices, such as an angular velocity sensor for detecting the angular velocity when the electronic device makes a rotational motion and an acceleration sensor for detecting the acceleration when the electronic device makes a linear motion. The angular velocity sensor, i.e., the gyroscope, has a wide range of applications. For example, the gyroscope can be used in conjunction with the camera on the electronic device to achieve an anti-shake function, thereby greatly improving the shooting ability of the electronic device; the acceleration sensor also has a wide range of applications. For example, when the user changes the direction of the electronic device, the acceleration sensor detects and cooperates with the control device of the electronic device to rotate the screen of the electronic device to adapt to the new direction. Thus, through the above-mentioned multiple detection devices, the functions of the electronic device can be made more comprehensive.

[0003] However, as the number of detection devices installed in the electronic device increases, the space occupied by the detection devices becomes larger. Correspondingly, the size of the electronic device also becomes larger, which is not conducive to the miniaturization and thin-and-light design of the electronic device. Therefore, the detection devices involved in the related technology have the problem of occupying a large amount of space. Summary of the Invention

The detection device further includes a first electrode plate, which is arranged inside the housing. In the extending direction of the first axis, the orthographic projection of the first electrode plate overlaps with the orthographic projection of at least one of the detection electrode plates partially. During the process of each movable plate moving in a direction perpendicular to the first axis, the overlapping area between the first electrode plate and the detection electrode plate is variable. During the process of each movable plate moving in the extending direction of the first axis, the distance between the first electrode plate and the detection electrode plate is variable; and / or The material of the elastic mounting member is a material with a variable resistance value. During the movement of the movable plate, the elastic mounting member deforms, so that the resistance value of the elastic mounting member is variable.

[0009] In a fifth aspect, an embodiment of the present application provides an electronic device, which includes a processor and a memory. The memory stores a program or instruction that can run on the processor. When the program or instruction is executed by the processor, the steps of the method described in the third aspect are implemented.

[0010] In a sixth aspect, an embodiment of the present application provides a readable storage medium, on which a program or instruction is stored. When the program or instruction is executed by a processor, the steps of the method described in the third aspect are implemented.

[0011] In a seventh aspect, an embodiment of the present application provides a chip, which includes a processor and a communication interface.

[0012] In an eighth aspect, an embodiment of the present application provides a computer program product, which is stored in a storage medium and is executed by at least one processor to implement the method described in the third aspect.

[0013] In the embodiments of the present application, since each movable plate can be mounted on the housing through different elastic mounting members, so that each movable plate can rotate or move relative to the housing, and since detection electrodes are provided on each movable plate, the detection device disclosed in the present application can realize the function of detecting angular velocity, that is, the detection device disclosed in the present application can be used as an angular velocity sensor. At the same time, since the detection device further includes a first electrode, and during the process of each movable plate moving in a direction perpendicular to the first axis, the overlapping area between the first electrode and the detection electrode is variable, and during the process of each movable plate moving in the extending direction of the first axis, the distance between the first electrode and the detection electrode is variable, this makes the capacitance between the first electrode and the detection electrode variable, so that the magnitude of the acceleration of each movable plate can be obtained through the variable capacitance, which makes the detection device disclosed in the present application can also realize the function of detecting acceleration; and / or, since the material of the elastic mounting member connecting the movable plate and the housing is a material with a variable resistance value, therefore, during the movement of the movable plate, the elastic mounting member is deformed, so that the resistance value of the elastic mounting member is variable, so that the magnitude of the acceleration of each movable plate can be obtained through the variable resistance value, which makes the detection device disclosed in the present application can also realize the function of detecting acceleration.

[0014] It can be seen from this that the detection device disclosed in the present application can not only be used as an angular velocity sensor, but also can be used as an acceleration sensor, that is, the detection device disclosed in the present application can realize multiple functions.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0018] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. generally belong to the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0019] The following will, in conjunction with the accompanying drawings, elaborate in detail on the detection device disclosed in the embodiments of the present application through specific embodiments and their application scenarios.

[0020] Please refer to Figures 1 - 8 , the present application discloses a detection device, and the disclosed detection device includes a housing 100, an elastic mounting member 200, and at least two movable plates 300.

[0021] The housing 100 is a basic component of the detection device, which can provide an installation basis for other components of the detection device, such as providing an installation basis for the elastic mounting member 200 and the movable plates 300. At the same time, the housing 100 can protect the elastic mounting member 200 and the movable plates 300.

[0022] The movable plates 300 are spaced apart and evenly arranged around the first axis. Each movable plate 300 is mounted on the housing 100 through a corresponding elastic mounting member 200. Since the elastic mounting member 200 can undergo elastic deformation, this enables each movable plate 300 to move relative to the housing. This movement can specifically be rotational movement, translational movement, or a combined movement of rotation and translation. A detection electrode plate 400 is provided on each movable plate 300. The detection electrode plate 400 can be used to detect the magnitude of the angular velocity generated during the rotational movement of each movable plate 300, so as to obtain the magnitude of the angular velocity generated during the rotation of the electronic device described later. That is, this detection device can specifically be an angular velocity sensor. Please refer to Figure 4 .

[0023] The detection device may further include a first electrode plate 500. The first electrode plate 500 is disposed inside the housing 100. In the extending direction of the first axis, the orthographic projection of the first electrode plate 500 partially overlaps with the orthographic projection of at least one detection electrode plate 400. In other words, a part of the orthographic projection of the first electrode plate 500 overlaps with a part of the orthographic projection of at least one detection electrode plate 400. That is, in the extending direction of the first axis, a part of the first electrode plate 500 is oppositely arranged with a part of at least one detection electrode plate 400. During the movement of each movable plate 300 in the direction perpendicular to the first axis, the overlapping area between the first electrode plate 500 and the detection electrode plate 400 is variable, that is, the overlapping area between the first electrode plate 500 and at least one detection electrode plate 400 is variable. During the movement of each movable plate 300 in the extending direction of the first axis, the distance between the first electrode plate 500 and the detection electrode plate 400 is variable, that is, the distance between the first electrode plate 500 and at least one detection electrode plate 400 is variable, so that the capacitance generated between the first electrode plate 500 and the detection electrode plate 400 changes, and the magnitude of the acceleration generated during the linear movement of each movable plate 300 is calculated through the changed capacitance, so as to obtain the magnitude of the acceleration generated during the movement of the electronic device. It can be seen that the detection device disclosed in the present application can also achieve the function of detecting acceleration, that is, this detection device can specifically be used as an acceleration sensor.

[0024] And / or, the material of the elastic mounting member 200 can be a material with variable resistance, specifically metal or semiconductor. During the movement of the movable plate 300, the elastic mounting member 200 can be squeezed or stretched by the moving movable plate 300, so that the elastic mounting member 200 can be deformed, and further the resistance value of the elastic mounting member 200 can be changed. At this time, the magnitude of the acceleration generated during the linear movement of each movable plate 300 can be obtained through the changed resistance value. It can be seen that the detection device disclosed in the present application can also realize the function of detecting acceleration, that is, the detection device can specifically be used as an acceleration sensor.

[0025] It should be noted that during the process of the detection device specifically detecting and outputting angular velocity data, that is, during the rotational movement of each movable plate 300, the detection device is not used to detect acceleration, that is, the detection device does not output acceleration data. Similarly, during the process of the detection device specifically detecting and outputting acceleration data, that is, during the linear movement of each movable plate 300, the detection device is not used to detect angular velocity.

[0026] In the embodiment of the present application, since each movable plate 300 can be mounted on the housing 100 through different elastic mounting members 200, so that each movable plate 300 can rotate or move relative to the housing 100, and since a detection electrode plate 400 is provided on each movable plate 300, this enables the detection device disclosed in the present application to realize the function of detecting angular velocity, that is, the detection device disclosed in the present application can be used as an angular velocity sensor. At the same time, since the detection device further includes a first electrode plate 500, and during the movement of each movable plate 300 in the direction perpendicular to the first axis, the overlapping area between the first electrode plate 500 and the detection electrode plate 400 is variable, and during the movement of each movable plate 300 in the extending direction of the first axis, the distance between the first electrode plate 500 and the detection electrode plate 400 is variable, this makes the capacitance between the first electrode plate 500 and the detection electrode plate 400 variable, so that the magnitude of the acceleration of each movable plate 300 can be obtained through the changed capacitance, which enables the detection device disclosed in the present application to also realize the function of detecting acceleration.

[0027] And / or, since the material of the elastic mounting member 200 connecting the movable plate 300 and the housing 100 is a material with variable resistance, therefore, during the movement of the movable plate 300, the elastic mounting member 200 is deformed, so that the resistance value of the elastic mounting member 200 is variable, and thus the magnitude of the acceleration of each movable plate 300 can be obtained through the changed resistance value, which enables the detection device disclosed in the present application to also realize the function of detecting acceleration.

[0028] As can be seen, the detection device disclosed in the present application can not only be used as an angular velocity sensor, but also as an acceleration sensor. That is, the detection device disclosed in the present application can achieve multiple functions. Compared with the conventional technical solution that uses multiple detection devices to achieve different functions, since the present application uses the same detection device to achieve multiple functions, to a certain extent, this can reduce the space of the electronic device occupied by the detection device, which is beneficial to the miniaturization and thin-and-light design of the electronic device.

[0029] Optionally, the detection electrode plate 400 may only include the mass block 410. The mass block 410 is specifically used to detect the magnitude of the angular velocity generated during the rotational movement of each movable plate 300. In this embodiment, the mass block 410 can also be used to detect the magnitude of the acceleration generated during the linear movement of each movable plate 300. Specifically, in the extending direction of the first axis, the orthographic projection of the first electrode plate 500 partially overlaps with the orthographic projection of the mass block 410, that is, a part of the orthographic projection of the first electrode plate 500 overlaps with a part of the orthographic projection of the mass block 410, so that a part of the first electrode plate 500 is oppositely arranged with a part of the mass block 410.

[0030] During the movement of each movable plate 300 in the direction perpendicular to the first axis, the overlapping area between the first electrode plate 500 and the mass block 410 is variable. During the movement of each movable plate 300 in the extending direction of the first axis, the distance between the first electrode plate 500 and the mass block 410 is variable, so that the capacitance generated between the first electrode plate 500 and the mass block 410 changes, thereby obtaining the magnitude of the acceleration generated during the linear movement of each movable plate 300. As can be seen, this can improve the utilization rate of the mass block 410.

[0031] In practical applications, the setting position of the mass block 410 may be limited, and thus there may be a situation where it is difficult for the orthographic projection of the first electrode plate 500 to partially overlap with the orthographic projection of the mass block 410 in the extending direction of the first axis. For this reason, in another embodiment, the detection electrode plate 400 may further include a second electrode plate spaced from the mass block 410, that is, there is a distance between the mass block 410 and the second electrode plate in the extending direction of the first axis and in the direction perpendicular to the first axis, so as to prevent short circuit between the mass block 410 and the second electrode plate caused by their contact.

[0032] In the extending direction of the first axis, the orthographic projection of the first electrode plate 500 partially overlaps with the orthographic projection of the second electrode plate, that is, a part of the orthographic projection of the first electrode plate 500 overlaps with a part of the orthographic projection of the second electrode plate, so that a part of the first electrode plate 500 is disposed opposite to a part of the second electrode plate. During the movement of each movable plate 300 in the direction perpendicular to the first axis, the overlapping area between the first electrode plate 500 and the second electrode plate is variable. During the movement of each movable plate 300 in the extending direction of the first axis, the distance between the first electrode plate 500 and the second electrode plate is variable. In this embodiment, the setting position of the additionally added second electrode plate can be flexibly selected. Therefore, in the extending direction of the first axis, the orthographic projection of the first electrode plate 500 is more likely to overlap with the orthographic projection of the second electrode plate, which is more convenient for realizing the detection of acceleration.

[0033] When the detection electrode plate 400 further includes a second electrode plate, in the extending direction of the first axis, only the orthographic projection of the first electrode plate 500 can be made to partially overlap with the orthographic projection of the second electrode plate, or a part of the orthographic projection of the first electrode plate 500 can be made to overlap with both a part of the orthographic projection of the mass block 410 and a part of the orthographic projection of the second electrode plate. This enables multiple varying capacitance values to be obtained both in the extending direction of the first axis and in the direction perpendicular to the first axis, and thus multiple acceleration data can be obtained, which can improve the detection accuracy to a certain extent.

[0034] Optionally, the number of the first electrode plates 500 can be one. At this time, one first electrode plate 500 can correspond to each detection electrode plate 400 simultaneously, that is, the first electrode plate 500 has a relatively large area.

[0035] In another embodiment, the number of the first electrode plates 500 can be at least two. Each first electrode plate 500 can be spaced in the housing 100. Each pair of movable plates 300 can be arranged in pairs. The two movable plates 300 in each pair of movable plates 300 can be distributed on both sides of the first axis. Among them, the two first electrode plates 500 correspond to each detection electrode plate 400 on a pair of movable plates 300 one by one. That is, at this time, one first electrode plate 500 corresponds to one detection electrode plate 400. This enables the area of each first electrode plate 500 in the present application to be designed to be smaller, so that one first electrode plate 500 just corresponds to one detection electrode plate 400, which can reduce the cost of manufacturing the first electrode plate 500 to a certain extent.

[0036] In this embodiment, during the movement of the detection device in a direction perpendicular to the first axis, specifically during the movement of each movable plate 300 in the setting direction of the pair of movable plates 300, the overlapping area between one of the two first electrode plates 500 and the corresponding detection electrode plate 400 will increase, and the overlapping area between the other of the two first electrode plates 500 and the corresponding detection electrode plate 400 will decrease. At this time, two capacitance values can be obtained, the two capacitance values are subtracted, and the acceleration magnitude generated during the movement of the pair of movable plates 300 in the setting direction of the two movable plates 300 included therein is calculated and obtained through the difference between the two capacitance values. This calculation method can be used to reduce errors to a certain extent.

[0037] Optionally, please refer to Figure 1 and Figure 2 above, the at least two first electrode plates 500 may specifically include a first sub-electrode plate 510 and a second sub-electrode plate 520 arranged at intervals. In the extending direction of the first axis, a part of the orthographic projection of the first sub-electrode plate 510 overlaps with a part of the orthographic projection of the detection electrode plate 400 on one of the pair of movable plates 300, and a part of the orthographic projection of the second sub-electrode plate 520 overlaps with a part of the orthographic projection of the detection electrode plate 400 on the other of the pair of movable plates 300. That is, the first sub-electrode plate 510 and the second sub-electrode plate 520 respectively correspond to the two detection electrode plates 400 on the pair of movable plates 300, and the moving directions of the pair of movable plates 300 are always the same.

[0038] In this embodiment, since the moving directions of the pair of movable plates 300 are always the same, during the movement of each movable plate 300 in the setting direction of the pair of movable plates 300, the overlapping area between the first sub-electrode plate 510 and the corresponding detection electrode plate 400 and one of the overlapping areas between the second sub-electrode plate 520 and the corresponding detection electrode plate 400 will increase, and the overlapping area between the first sub-electrode plate 510 and the corresponding detection electrode plate 400 and the other of the overlapping areas between the second sub-electrode plate 520 and the corresponding detection electrode plate 400 will decrease, and the increase amount and the decrease amount of the above overlapping areas are basically the same. At this time, two capacitance values can be obtained, and the acceleration magnitude generated during the movement of the pair of movable plates 300 in the setting direction of the two movable plates 300 included therein can be obtained by subtracting the two capacitance values.

[0039] Optionally, only one pair of movable plates 300 may be provided.

[0040] In another embodiment, two pairs of movable plates 300 may be provided. Specifically, please refer to Figure 1 and Figure 2, the movable plate 300 may include a first movable plate 310 and a second movable plate 320 arranged in pairs in a first direction, and a third movable plate 330 and a fourth movable plate 340 arranged in pairs in a second direction. That is, the at least two movable plates 300 described above may specifically include a first movable plate 310, a second movable plate 320, a third movable plate 330, and a fourth movable plate 340, and the first direction, the second direction, and the first axis intersect pairwise. Optionally, the first direction, the second direction, and the first axis may be perpendicular to each other pairwise.

[0041] The first movable plate 310, the third movable plate 330, the second movable plate 320, and the fourth movable plate 340 may be arranged at intervals and evenly around the first axis. Each of the above first electrode plates 500 corresponds to each detection electrode plate 400 on each movable plate 300 one by one. That is, two first electrode plates 500 may correspond to each detection electrode plate 400 on a pair of movable plates 300 one by one, and the other two first electrode plates 500 may correspond to each detection electrode plate 400 on the other pair of movable plates 300 one by one, so that each detection electrode plate 400 corresponds to a first electrode plate 500.

[0042] In the extending direction of the first axis, the orthographic projections of the first electrode plates 500 partially overlap with the orthographic projections of the corresponding detection electrode plates 400, that is, part of the orthographic projection of each first electrode plate 500 overlaps with part of the orthographic projection of the corresponding detection electrode plate 400. During the movement of each movable plate 300, since each detection electrode plate 400 corresponds to a first electrode plate 500, this enables the present application to not only obtain the magnitude of the acceleration generated during the movement of the above-mentioned pair of movable plates 300 along the setting direction of the two movable plates it includes, but also obtain the magnitude of the acceleration generated during the movement of the above-mentioned other pair of movable plates 300 along the setting direction of the two movable plates it includes. That is, the detection device disclosed in the present application can detect and output the magnitudes of accelerations in multiple directions, making the functions of the electronic device more comprehensive.

[0043] Optionally, please refer to Figure 1 and Figure 2 , in addition to including the first sub-electrode plate 510 and the second sub-electrode plate 520, the at least two first electrode plates 500 may further include a third sub-electrode plate 530 and a fourth sub-electrode plate 540, and the first sub-electrode plate 510, the second sub-electrode plate 520, the third sub-electrode plate 530, and the fourth sub-electrode plate 540 correspond to each detection electrode plate 400 on each movable plate 300 one by one. That is, each detection electrode plate 400 on each movable plate 300 corresponds to a first electrode plate 500, and in the extending direction of the first axis, part of the orthographic projection of the first sub-electrode plate 510, part of the orthographic projection of the second sub-electrode plate 520, part of the orthographic projection of the third sub-electrode plate 530, and part of the orthographic projection of the fourth sub-electrode plate 540 overlap with part of the orthographic projection of the corresponding detection electrode plates 400.

[0044] Specifically, in the extending direction of the first axis, a part of the orthographic projection of the first sub-plate 510 overlaps with a part of the orthographic projection of the detection plate 400 on the first movable plate 310, a part of the orthographic projection of the second sub-plate 520 overlaps with a part of the orthographic projection of the detection plate 400 on the second movable plate 320, a part of the orthographic projection of the third sub-plate 530 overlaps with a part of the orthographic projection of the detection plate 400 on the third movable plate 330, and a part of the orthographic projection of the fourth sub-plate 540 overlaps with a part of the orthographic projection of the detection plate 400 on the fourth movable plate 340.

[0045] In this embodiment, since the first sub-plate 510, the second sub-plate 520, the third sub-plate 530, and the fourth sub-plate 540 correspond to the respective detection plates 400 on the respective movable plates 300 one by one, during the movement of the respective movable plates 300, the detection device can detect and output the acceleration magnitudes in multiple directions. Specifically, by calculating the difference between the two capacitance values generated when the first movable plate 310 and the second movable plate 320 move along the first direction, the acceleration magnitude generated when the first movable plate 310 and the second movable plate 320 move along the first direction is obtained. By calculating the difference between the two capacitance values generated when the third movable plate 330 and the fourth movable plate 340 move along the second direction, the acceleration magnitude generated when the third movable plate 330 and the fourth movable plate 340 move along the second direction is obtained, which can be further used to reduce errors.

[0046] Optionally, a third plate is provided on the inner bottom wall 110 of the housing 100, and the third plate is specifically used to detect the angular velocity magnitude generated during the rotational movement of the respective movable plates 300. In this embodiment, the third plate can also be used to detect the acceleration magnitude generated during the linear movement of the respective movable plates 300. Specifically, in the extending direction of the first axis, the orthographic projections of the respective detection plates 400 are all located within the orthographic projection of the third plate, that is, the respective detection plates 400 are disposed opposite to the third plate. During the movement of the respective movable plates 300 along the extending direction of the first axis, the distance between the detection plate 400 and the third plate increases or decreases, which enables the change in capacitance to be easily obtained by detecting the changing distance between the detection plate 400 and the third plate, so as to obtain the acceleration magnitude generated during the movement of the respective movable plates 300 along the extending direction of the first axis.

[0047] In this embodiment, since the third electrode plate can be used to detect the magnitude of the acceleration generated during the linear motion of each movable plate 300, this can improve the utilization rate of the third electrode plate. At the same time, since the above-mentioned first electrode plate 500 can also obtain the magnitude of the acceleration generated during the movement of each movable plate 300 along the extension direction of the first axis, this enables the present application to improve the detection accuracy of the acceleration generated during the movement of each movable plate 300 along the extension direction of the first axis to a certain extent. Of course, in other embodiments, the present application may also not detect the magnitude of the acceleration generated during the linear motion of each movable plate 300 through the third electrode plate.

[0048] Optionally, please refer to Figures 1 to 3 , the detection device may further include an elastic connecting member 600. In the direction around the first axis, adjacent movable plates 300 may be connected by the elastic connecting member 600, and the material of the elastic connecting member 600 may be plastic.

[0049] In another embodiment, the material of the elastic connecting member 600 may be a shape memory alloy, that is, the elastic connecting member 600 can conduct electricity, and when the elastic connecting member 600 is energized, adjacent movable plates 300 are relatively fixed through the elastic connecting member 600. That is, at this time, the elastic connecting member 600 can become hard (please refer to Figure 3 and Figure 5 , the dotted box around the elastic connecting member 600 indicates that the elastic connecting member 600 is in a hard state at this time), so as to maintain the current shape, so that adjacent two movable plates 300 are an integral body, that is, each movable plate 300 is an integral body. At this time, the detection device disclosed in the present application can be used as an acceleration sensor. Since each movable plate 300 can be an integral body, and further, during the movement of each movable plate 300, the moving directions of each movable plate 300 are more consistent, so that it is easier to obtain the magnitude of the acceleration generated during the movement of each movable plate 300.

[0050] To ensure the setting stability of each movable plate 300, that is, to ensure the movement stability of each movable plate 300, the detection device may further include a limiting component 700. Each movable plate 300 surrounds the limiting component 700. The limiting component 700 includes a limiting block 710 and at least two pairs of elastic limiting members 720. The limiting block 710 is installed on the inner bottom wall 110 of the housing 100, and the center of the limiting block 710 coincides with the first axis. Each elastic limiting member 720 surrounds the limiting block 710, and each movable plate 300 corresponds to at least one elastic limiting member 720, so that the movable plate 300 is connected to the limiting block 710 through the elastic limiting member 720, that is, each movable plate 300 is connected to the same limiting component 700, so that the limiting component 700 can limit each movable plate 300 at the same time.

[0051] Optionally, the elastic limiting member 720 may be made of plastic.

[0052] In another embodiment, the elastic limiting member 720 may be made of a variable resistance material, specifically metal or semiconductor. During the movement of the movable plate 300, the elastic limiting member 720 can be squeezed or stretched by the movable plate 300 connected thereto, so that the elastic limiting member 720 can be deformed, and further the resistance value of the elastic limiting member 720 can be changed. At this time, the magnitude of the acceleration generated by each movable plate 300 in its moving direction can be obtained through the changed resistance value.

[0053] In this embodiment, since the magnitude of the acceleration generated by each movable plate 300 in its moving direction can also be obtained through the changed overlapping area between the first electrode plate 500 and the detection electrode plate 400 and / or the elastic mounting member 200, the present application can obtain multiple accelerations generated by each movable plate 300 in its moving direction, which can be further used to reduce errors.

[0054] Optionally, each movable plate 300 may be connected to the limiting block 710 only through one elastic limiting member 720.

[0055] In another embodiment, please refer to Figure 5 , each movable plate 300 may be connected to the limiting block 710 through at least two elastic limiting members 720. Since the magnitude of the acceleration generated by each movable plate 300 in its moving direction can be obtained through the changed resistance value of the elastic limiting member 720, when each movable plate 300 is connected to the limiting block 710 through at least two elastic limiting members 720, multiple accelerations generated by each movable plate 300 in its moving direction can be obtained through the changed resistance values of the multiple elastic limiting members 720, which can be further used to reduce errors.

[0056] Optionally, please refer to Figure 3 , the number of the elastic mounting members 200 may be at least two. Each movable plate 300 may be mounted on the housing 100 only through one elastic mounting member 200, that is, one movable plate 300 corresponds to one elastic mounting member 200. During the movement of each movable plate 300, the elastic mounting member 200 corresponding to the moving movable plate 300 can be deformed, so that the resistance value of each elastic mounting member 200 can be changed, thereby facilitating obtaining the magnitude of the acceleration generated when each movable plate 300 moves in the corresponding direction.

[0057] In this embodiment, the at least two elastic mounting members 200 may include a first elastic member 210, a second elastic member 220, a third elastic member 230, and a fourth elastic member 240. Each movable plate 300 may be mounted on the inner sidewall 120 of the housing 100 only through one elastic mounting member 200. That is, the first movable plate 310 may be mounted on the inner sidewall 120 of the housing 100 only through one first elastic member 210, the second movable plate 320 may be mounted on the inner sidewall 120 of the housing 100 only through one second elastic member 220, the third movable plate 330 may be mounted on the inner sidewall 120 of the housing 100 only through one third elastic member 230, and the fourth movable plate 340 may be mounted on the inner sidewall 120 of the housing 100 only through one fourth elastic member 240.

[0058] During the process of each movable plate 300 moving in the first direction, the resistance value of one of the first elastic member 210 and the second elastic member 220 increases, and the resistance value of the other of the first elastic member 210 and the second elastic member 220 decreases. At this time, the difference between the two obtained resistance values can be calculated, so as to obtain the magnitude of the acceleration generated by the first movable plate 310 and the second movable plate 320 when moving in the first direction. During the process of each movable plate 300 moving in the second direction, the resistance value of one of the third elastic member 230 and the fourth elastic member 240 increases, and the resistance value of the other of the third elastic member 230 and the fourth elastic member 240 decreases. At this time, the difference between the two obtained resistance values can be calculated, so as to obtain the magnitude of the acceleration generated by the third movable plate 330 and the fourth movable plate 340 when moving in the second direction.

[0059] In another embodiment, please refer to Figure 5 , each movable plate 300 may be mounted on the housing 100 through at least two elastic mounting members 200, and during the movement of each movable plate 300, each elastic mounting member 200 corresponding to the moving movable plate 300 can be deformed so that the resistance value of each elastic mounting member 200 is variable. Specifically, the number of the first elastic members 210, the number of the second elastic members 220, the number of the third elastic members 230, and the number of the fourth elastic members 240 may all be at least two. At this time, the first movable plate 310 may be mounted on the inner sidewall 120 of the housing 100 through at least two first elastic members 210, the second movable plate 320 may be mounted on the inner sidewall 120 of the housing 100 through at least two second elastic members 220, the third movable plate 330 may be mounted on the inner sidewall 120 of the housing 100 through at least two third elastic members 230, and the fourth movable plate 340 may be mounted on the inner sidewall 120 of the housing 100 through at least two fourth elastic members 240.

[0060] During the process of each movable plate 300 moving in the first direction, the resistance value of one of the first elastic member 210 and the second elastic member 220 increases, and the resistance value of the other of the first elastic member 210 and the second elastic member 220 decreases. Specifically, the resistance values of at least two of the first elastic members 210 will all increase, and correspondingly, the resistance values of at least two of the second elastic members 220 will all decrease, or the resistance values of at least two of the first elastic members 210 will all decrease, and correspondingly, the resistance values of at least two of the second elastic members 220 will all increase. That is, a plurality of resistance values corresponding to the plurality of first elastic members 210 and a plurality of resistance values corresponding to the plurality of second elastic members 220 will be obtained, thereby forming multiple pairs of resistance values. At this time, by calculating the difference between each pair of resistance values in the multiple pairs of resistance values, a plurality of accelerations generated when the first movable plate 310 and the second movable plate 320 move in the first direction can be obtained, which can be used to reduce errors.

[0061] Similarly, during the process of each movable plate 300 moving in the second direction, the resistance value of one of the third elastic member 230 and the fourth elastic member 240 increases, and the resistance value of the other of the third elastic member 230 and the fourth elastic member 240 decreases. Specifically, the resistance values of at least two of the third elastic members 230 will all increase, and correspondingly, the resistance values of at least two of the fourth elastic members 240 will all decrease, or the resistance values of at least two of the third elastic members 230 will all decrease, and correspondingly, the resistance values of at least two of the fourth elastic members 240 will all increase. That is, a plurality of resistance values corresponding to the plurality of third elastic members 230 and a plurality of resistance values corresponding to the plurality of fourth elastic members 240 will be obtained, thereby forming multiple pairs of resistance values. At this time, by calculating the difference between each pair of resistance values in the multiple pairs of resistance values, a plurality of accelerations generated when the third movable plate 330 and the fourth movable plate 340 move in the second direction can be obtained, which can be used to reduce errors.

[0062] Optionally, in the extending direction of the first axis, the first electrode plate 500, the movable plate 300, and the inner bottom wall 110 of the housing 100 can be sequentially arranged. During the specific installation process, the movable plate 300 is first installed on the inner side wall 120 of the housing 100, and then the first electrode plate 500 is installed on the inner side wall 120 of the housing 100, so that in the extending direction of the first axis, a part of the orthographic projection of the first electrode plate 500 preferably overlaps with a part of the orthographic projection of one of the detection electrode plates 400.

[0063] In another embodiment, along the extension direction of the first axis, the movable plate 300, the first electrode plate 500, and the inner bottom wall 110 of the housing 100 may be arranged in sequence, that is, the first electrode plate 500 is located between the movable plate 300 and the inner bottom wall 110 of the housing 100, so as to make full use of the space between the movable plate 300 and the inner bottom wall 110 of the housing 100. To a certain extent, this can reduce the size of the housing 100 along the extension direction of the first axis, thereby reducing the space occupied by the detection device in the electronic device.

[0064] Optionally, according to the above content, the first electrode plate 500 may be located between the inner bottom wall 110 of the housing 100 and the movable plate 300.

[0065] In another embodiment, the first electrode plate 500 may be embedded in the inner bottom wall 110 of the housing 100, which can appropriately reduce the distance between the movable plate 300 and the inner bottom wall 110 of the housing 100, thereby further reducing the size of the housing 100 along the extension direction of the first axis, and further reducing the space occupied by the detection device in the electronic device.

[0066] Optionally, the present application also discloses an electronic device, including a housing and the detection device described above. The housing has an inner cavity, and the detection device may be disposed in the inner cavity, so that the functions of the electronic device can be more comprehensive through the detection device.

[0067] Optionally, please refer to Figure 6 , the embodiments of the present application also disclose a detection method, which is applied to the detection device described in any of the above embodiments. The detection method includes: S100. During a first time period, control the detection device to vibrate for a preset duration and output angular velocity data.

[0068] Here, the preset duration refers to the vibration duration of the detection device, that is, the duration from the start of the main vibration of the detection device to the end of the main vibration of the detection device. Specifically, during the first time period, the main vibration of the detection device may be started first, and then the angular velocity data may be output immediately, or after waiting for a preset time after starting the main vibration, that is, after the main vibration of each movable plate 300 is stable, the detection device outputs the angular velocity data. At this time, the obtained angular velocity data is relatively accurate. Generally, since the requirements for the obtained angular velocity data are relatively high, the present application may continuously output multiple angular velocity data during the first time period. Optionally, the above preset time may be 5 ms, that is, after the detection device starts vibrating and waits for 5 ms, the angular velocity data is output. Of course, the embodiments of the present application do not make specific limitations on this.

[0069] S200. During a second time period, output acceleration data.

[0070] Specifically, after the main vibration of each of the above movable plates 300 completely stops, within the second time period, the detection device can output acceleration data, where the first time period and the second time period do not overlap. In other words, the detection device does not output angular velocity data and acceleration data simultaneously.

[0071] Optionally, according to the above content, since the electronic device has relatively high requirements for the angular velocity data generated by the detection device, this application can make the amount of angular velocity data output by the detection device much larger than the amount of acceleration data output. Correspondingly, the time used by the detection device to detect and output angular velocity data can be greater than the time used by the detection device to detect and output acceleration data, that is, the duration of the first time period can be greater than the duration of the second time period.

[0072] In addition, acceleration data can be output immediately after the main vibration of the detection device is turned off. At this time, the above preset duration is equal to the duration of the first time period; or, after the main vibration of the detection device is turned off, acceleration data is output after waiting for a preset time interval. At this time, the duration of the first time period includes the preset duration and the preset time interval. When the second time period starts, the main vibration of the detection device has basically completely stopped, so the accuracy of the acceleration data can be improved. For example, the duration of the first time period can be 100 ms, the preset duration of the detection device vibration is 95 ms, and the preset time waited after the main vibration is turned on is 5 ms. This makes the duration of the detection device continuously outputting angular velocity data 90 ms. After the main vibration of each movable plate 300 completely stops, specifically, after another 5 ms, it enters the second time period to start outputting acceleration data. Thus, it can be seen that the detection device can output acceleration data once every 100 ms. Of course, the embodiments of this application do not make specific limitations on this, that is, this application can flexibly adjust the time used by the detection device to detect and output angular velocity data and the time used by the detection device to detect and output acceleration data.

[0073] In the embodiments of this application, since the detection method disclosed in this application is applied to the detection device described above, and within the first time period, the detection device can output angular velocity data, and within the second time period, the detection device can output acceleration data, and the first time period and the second time period do not overlap, this enables the detection device to be used not only as an angular velocity sensor but also as an acceleration sensor. That is, this application can achieve multiple functions with the same detection device, which can, to a certain extent, reduce the space occupied by the detection device in the electronic device and is conducive to the miniaturization and thin-and-light design of the electronic device.

[0076] In the detection device disclosed in the embodiment of the present application, since the detection device can output angular velocity data during the first period and acceleration data during the second period, and the first period and the second period do not overlap, the detection device can not only be used as an angular velocity sensor, but also be used as an acceleration sensor. That is, the present application can implement multiple functions by using the same detection device, which can reduce the space occupied by the detection device in the electronic device to a certain extent, and is beneficial to the miniaturization and thin-and-light design of the electronic device.
