Description

Technical Field

[0001] The utility model relates to the technical field of testing equipment, in particular to a testing device. Background Art

[0002] With the rapid development of technology, intelligence has become a fundamental requirement in the design and manufacture of new vehicles. One of the core characteristics of smart cars is their rich functionality and convenient human-computer interaction. Traditional manual input methods such as buttons and touch screens have been gradually replaced by more advanced interactive technologies such as voice input, gesture recognition, and eye contact. These new interaction methods have greatly enhanced the user experience, making driving and riding safer and more comfortable.

[0003] In these new interaction methods, sensors such as cameras and microphones play a crucial role. They are key devices for implementing command input. To enhance the human-computer interaction experience, these sensors must ensure high accuracy and sensitivity while minimizing false recognition rates. This places higher demands on data collection, training, and testing equipment during the development process. Factors such as the sensor's placement, posture, distance from the user, and inter-device coupling all affect information collection and, in turn, recognition accuracy.

[0004] A common approach in existing technology is to simulate a car cockpit environment to build a data collection and testing environment. Devices such as DMS cameras (Driver Monitoring System cameras), OMS cameras (Occupant Monitoring System cameras), and microphones are placed in the same or similar locations as in an actual vehicle, and then connected to the system for data collection, debugging, and testing. However, this testing equipment requires a large space, lacks flexibility, and is costly.

[0005] Another approach is to utilize an existing general-purpose test bench, or even an ordinary desktop, to temporarily secure the sensor equipment and test system to the bench for testing. While this addresses space and cost issues to a certain extent, the limitations of the test bench environment make it difficult to precisely match the camera and microphone placement with the actual vehicle, and the relative positions of the sensors are prone to change. This impacts the collected data and debugged algorithm results. When migrated to a real vehicle for use, poor adaptability and compatibility may lead to misidentification or low sensitivity, ultimately directly impacting the user experience.

[0036] The following combination Figure 1-Figure 5 The test device of the present invention is described.

[0037] The testing device is used to test the image acquisition unit 40 and the sound acquisition unit 50 of the vehicle cockpit domain controller. The testing device provided by the embodiment of the present utility model includes a housing 10 and a data processing unit.

[0038] like Figure 2 and Figure 3As shown, a hollow cavity 111 is formed within the housing 10. At least one image acquisition unit 40 and at least one sound acquisition unit 50 are integrated within this cavity 111. The dimensions of the housing 10 are tailored to the size of the vehicle cockpit domain controller being tested, ensuring that the test device is compatible with different controller models. Multiple positioning elements, such as positioning grooves, adhesives, and fixing plates 14, are provided within the cavity 111. Each image acquisition unit 40 and each sound acquisition unit 50 is encapsulated and secured in a relatively fixed position. Specifically, each image acquisition unit 40 and each sound acquisition unit 50 is secured within the cavity 111 by the positioning elements. The position and posture of each image acquisition unit 40 and each sound acquisition unit 50 are fixed, and the distance between them remains constant, with a predetermined distance. For example, the distance between adjacent acquisition units can be equal or unequal, allowing for various testing scenarios. It should be noted that the placement of the acquisition units within the housing 10 is determined based on actual vehicle calculations. The positioning elements can be moved along the length or width of the cavity 111 to accommodate acquisition units in different positions and postures. This test device offers excellent universal applicability.

[0039] The limiting unit in the embodiment of the present invention may also be an adhesive, a fastener, or a clip, which can limit and fix the image acquisition unit 40 and the sound acquisition unit 50 in the cavity 111 .

[0040] The bottom surface of the cavity 111 is provided with at least one camera port, and the camera end of each image acquisition unit 40 is embedded in the corresponding camera port to facilitate the acquisition of electrical signals outside the shell 10. The camera end of the image acquisition unit 40 can be lower than the camera port, can be flush with the outer wall surface of the camera port, or can protrude from the camera port. It should be noted that the shell 10 is installed in the cockpit area, and the installation surface of the shell 10 is adjacent to the bottom surface of the cavity 111. The installation of the shell 10 in the car cockpit area will not affect the data acquisition of the image acquisition unit 40 and the sound acquisition unit 50. Furthermore, each image acquisition unit 40 and each sound acquisition unit 50 are electrically connected to the data processing module via wired or wireless means. The data processing module receives the electrical signals collected by each image acquisition unit 40 and each sound acquisition unit 50, processes them in real time, and ultimately generates test results.

[0041] The test device provided in the embodiment of the present invention uses multiple limiting units to encapsulate and fix at least one image acquisition unit 40 and at least one sound acquisition unit 50 in a fixed positional relationship within the cavity 111, ensuring that the positions of each image acquisition unit 40 and each sound acquisition unit 50 are relatively fixed under any circumstances, thereby ensuring the consistency of data acquisition and testing, improving the reliability of test results, and being suitable for performance evaluation of various automotive cockpit domain controllers.

[0042] The image acquisition unit 40 in the embodiment of the present invention includes a driver monitoring system camera (DMS camera) and an passenger monitoring system camera (OMS camera). The sound acquisition unit 50 includes a microphone.

[0043] like Figure 3 and Figure 4 As shown, the housing 10 includes a body 11 and a cover 12. A cavity 111 is disposed within the body 11. The cavity 111 has an opening that is disposed opposite to the bottom surface of the cavity 111, facilitating the packaging of the image acquisition units 40 and the sound acquisition units 50 in a fixed position within the cavity 111. The cover 12 covers the opening to ensure a tight seal.

[0044] The cover body 12 includes a cover portion 121 and a limiting portion 122, and the limiting portion 122 is connected to the cover portion 121. The connection between the limiting portion 122 and the cover portion 121 matches that of the main body 11. When the main body 11 is a rectangular structure, the limiting portion 122 and the cover portion 121 are perpendicular. The cover portion 121 covers the opening and encapsulates each image acquisition unit 40 and each sound acquisition unit 50 within the main body 11. The side wall of the cavity 111 is also provided with a notch 112, which is adapted to the size of the limiting portion 122. The limiting portion 122 is embedded in the notch 112, which can be positioned to achieve rapid packaging. It should be noted that the length of the notch 112 can be greater than the length of the limiting portion 122. In the embodiment of the utility model, the number of limiting portions 122 and the notch is the same, and can be multiple, with the multiple notches being spaced apart along the length of the main body 11 and the multiple limiting portions 122 being spaced apart along the length of the cover portion 121. In order to further enhance the fixing effect, the cover portion 121 is detachably connected to the body 11 via fasteners, which may be bolts, to ensure reliability under different test conditions.

[0045] The limiting unit includes at least one first limiting unit and at least one second limiting unit. The first limiting unit and the second limiting unit are arranged at intervals along the length direction of the cavity 111. Each first limiting unit is used to limit the corresponding image acquisition unit 40, and each second limiting unit is used to limit the corresponding sound acquisition unit 50.

[0046] like Figure 2 and Figure 3As shown, there are two image acquisition units 40, namely 40a and 40b. There are four sound acquisition units 50, namely 50a, 50b, 50c, and 50d. There are two first limiting units, which can be the same or different. The first limiting unit includes a fixing plate 14, through which the image acquisition unit 40 can be fixed to the bottom surface of the cavity 111. The first limiting unit can be an adhesive, through which the image acquisition unit 40 can be adhered to the bottom surface of the cavity 111. The first limiting unit can be a slot provided on the bottom surface of the cavity 111, in which the image acquisition unit 40 and the sound acquisition unit 50 are embedded. There are four second limiting units, which can be the same or different. Similarly, the second limiting unit can also be a fixing plate 14, an adhesive, and a slot provided on the bottom surface of the cavity 111. In one embodiment, the first first limiting unit is located between the first and second second limiting units, and the second first limiting unit is located between the third and fourth second limiting units. Specifically, the first image acquisition unit 40a (driver monitoring system camera) is located between the first and second sound acquisition units 50a, 50b, and the second image acquisition unit (passenger detection monitoring system camera) is located between the third and fourth sound acquisition units 50c, 50d.

[0047] In a specific embodiment, the first limiting unit includes a fixing plate 14 and at least three first limiting posts 13, the bottom of each first limiting post 13 being fixed to the bottom surface of the cavity 111 at intervals along the circumference of the camera port. Furthermore, the fixing plate 14 is covered on the top surfaces of the multiple first limiting posts 13, and the top of each first limiting post 13 is detachably connected to the fixing plate 14; the multiple first limiting posts 13, the bottom surface of the cavity 111, and the fixing plate 14 are arranged to form a limiting space. When it is necessary to install the image acquisition unit 40, the fixing plate 14 is removed from the first limiting post 13, and the image acquisition unit 40 is embedded in the limiting space. After completion, the fixing plate 14 is connected to the limiting post via fasteners (bolts) to fix the image acquisition unit 40.

[0048] In addition, when there are three first limiting columns 13, a structure compatible with the image acquisition unit 40 can be formed with the help of the side wall of the cavity 111 to limit the image acquisition unit 40 and prevent it from moving up and down during installation, affecting the acquisition and test results.

[0049] The first limiting unit in the embodiment of the present invention further includes a first adhesive component, and the image acquisition unit 40 can be fixed to the bottom surface of the cavity 111 through the first adhesive component. The first adhesive component includes an adhesive.

[0050] In one embodiment, at least three first limiting columns 13 are provided at circumferential intervals around the camera port, the image acquisition unit 40 is fixed to the bottom of the cavity 111 by a first adhesive, and the fixing plate 14 is covered on the top of the multiple first limiting columns 13, which has a good fixing effect, ensures the stability of the image acquisition unit 40, and improves the acquisition and test results.

[0051] The second limiting unit in the embodiment of the present invention includes a second adhesive member, and the sound collecting unit 50 is fixed to the bottom surface of the cavity 111 through the second adhesive member. The second adhesive member includes an adhesive.

[0052] The bottom surface of the cavity 111 is provided with at least one collection port. The collection end of each sound collection unit 50 is embedded in the corresponding collection port. The sound collection unit 50 can directly contact the sound source, thereby improving the collection effect. Furthermore, at least three second limiting columns 15 are arranged at intervals along the circumference of the collection port to limit the sound collection unit 50. It should be noted that the position of the second limiting columns 15 is set according to the structure of the sound collection unit 50 to prevent the sound collection unit 50 from moving. Figure 5 As shown, three second limiting posts 15 can mate with one inner wall of cavity 111 to restrain the sound collection unit 50. The second limiting posts 15 are provided with limiting grooves, into which the corners of the sound collection unit 50 engage, thereby limiting the position of the sound collection unit 50. The second limiting units at both ends of cavity 111 can be equipped with one or two second limiting posts 15, using two or three inner walls of cavity 111 to restrain the sound collection unit 50.

[0053] In the embodiment of the present invention, the image acquisition unit 40 and the sound acquisition unit 50 are integrated into the cavity 111 through the first limiting unit and the second limiting unit. The positions of the first limiting unit and the second limiting unit are adjusted according to the adapted vehicle so that their relative positions and postures are fixed, and image, sound and other data of the driver and passengers in the cockpit area are collected. Data can be collected at different design positions, with high flexibility and low cost.

[0054] To stably secure the housing 10 within the cockpit, the test device also includes a base 30, which secures the housing 10 within the cockpit. It should be noted that the mounting surface of the housing 10 is adjacent to the bottom surface of the cavity 111, which does not affect data acquisition by the image acquisition unit 40 and the sound acquisition unit 50. The base 30 can be secured using a magnetic element, a suction cup, screws, or spring clips, depending on the environment.

[0055] Furthermore, to collect data in various orientations, a universal adjustment member 20 is provided between the housing 10 and the base 30. The top of the universal adjustment member 20 is connected to the housing 10, and the connection surface between the housing 10 and the universal adjustment member 20 is adjacent to the bottom surface of the cavity 111. The housing 10 can rotate relative to the universal adjustment member 20. The bottom of the universal adjustment member 20 is connected to the base 30, and the universal adjustment member 20 can rotate relative to the base 30, thereby adjusting the angle of the housing 10, that is, adjusting the angle of the image acquisition unit 40 and the sound acquisition unit 50. It will be understood that because the positions of the first and second limiting units are relatively fixed, the relative positions and postures of the image acquisition unit 40 and the sound acquisition unit 50 are fixed during the adjustment process.

[0056] like Figure 1 and Figure 2 As shown, the universal adjustment member 20 includes a first side plate 21, a second side plate 22, an adjustment member 23, a first rotating member 24 and a second rotating member 25. The adjustment member 23 passes through the first side plate 21 and the second side plate 22 in sequence. The adjustment member 23 can be a bolt. Screwing the bolt can adjust the distance between the first side plate 21 and the second side plate 22.

[0057] The top of the first rotating member 24 is fixedly connected to the shell 10. The shell 10 is provided with a threaded hole. The top of the first rotating member 24 is threadedly connected to the shell 10 through the threaded hole to achieve fixation. In one embodiment, a reinforcing column is provided in the cavity 111, and the threaded hole is provided on the reinforcing column, so that the connection is more stable. The reinforcing column can be the first limiting column 13 or the second limiting column 15. A first fulcrum is provided at the bottom of the first rotating member 24. The first fulcrum is clamped at the upper part between the first side plate 21 and the second side plate 22. Screwing the adjustment member 23 increases the distance between the first side plate 21 and the second side plate 22. The first fulcrum can be rotated to adjust the position of the shell 10. After it is in the target position, the adjustment member 23 is screwed in the opposite direction to reduce the first side plate 21 and the second side plate 22, so that the first fulcrum is fixed between the first side plate 21 and the second side plate 22. The first fulcrum can be a spherical structure.

[0058] The bottom of the second rotating member 25 is connected to the base 30. The top of the second rotating member 25 is provided with a second fulcrum, which is sandwiched between the first side panel 21 and the second side panel 22. The adjustment member 23 is turned to increase the distance between the first side panel 21 and the second side panel 22. The second fulcrum can be rotated to adjust the position of the first side panel 21 and the second side panel 22, that is, to adjust the angle of the housing 10. After reaching the target position, the adjustment member 23 is turned to reduce the distance between the first side panel 21 and the second side panel 22, so that the second fulcrum is fixed between the first side panel 21 and the second side panel 22. The second fulcrum can be a spherical structure. It should be noted that in the actual adjustment process, both can be adjusted simultaneously.

[0059] To improve stability during the adjustment process, the embodiment of the present invention is provided with matching first grooves on the opposing sides of the first side panel 21 and the second side panel 22. That is, the two first grooves are arranged to form a first limiting structure that matches the first fulcrum (the first fulcrum is a spherical structure, and the first limiting structure is a spherical structure). The first fulcrum is embedded in the first groove, and the first fulcrum can rotate within the first groove. Similarly, the first side panel 21 and the second side panel 22 are also provided with matching second grooves on the opposing sides. That is, the two second grooves are arranged to form a second limiting structure that matches the second fulcrum (the second fulcrum is a spherical structure, and the second limiting structure is a spherical structure). The second fulcrum is embedded in the second groove, and the second fulcrum can rotate within the second groove.

[0060] In this embodiment of the present invention, the first rotating member 24 is connected to the housing 10 in a liftable manner, such as by a telescopic member. The first rotating member 24 is bolted to the housing 10, and the first rotating member 24 can be raised or lowered by adjusting the length of the threaded connection. Alternatively, the second rotating member 25 is connected to the base 30 in a liftable manner, such as by a telescopic member. The second rotating member 25 is threadedly connected to the base 30, and the second rotating member 25 can be raised or lowered by adjusting the length of the threaded connection. By configuring the first and second rotating members 24, 25 as lifts, this embodiment of the present invention allows the height of the housing 10 (the image acquisition unit 40 and the sound acquisition unit 50) to be adjusted to suit different vehicle environments.

[0061] The test device provided by the embodiment of the present utility model has high integration, rich functions, stability, and is convenient for data collection and testing; it is also small in size and low in cost, can be adapted to different vehicle environments, and can be mass-produced.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
