Description

Technical Field

[0001] The present application relates to the technical field of vehicle-mounted camera testing, and in particular to a vehicle-mounted camera module testing fixture. Background Art

[0002] At present, vehicle-mounted camera modules play a key role in vehicle safety, comfort and intelligence.

[0003] In related technologies, after production, vehicle-mounted camera modules require a series of imaging performance tests. Currently, these tests are often performed by holding the vehicle-mounted camera module or by using a bracket to secure the module. However, holding the vehicle-mounted camera module is unstable and can easily affect the imaging quality; the bracket can only be used for testing in a fixed position within the vehicle, and once the vehicle-mounted camera module is mounted on the bracket, its installation position cannot be adjusted according to testing needs. This type of imaging test cannot meet current testing requirements.

[0004] Therefore, it is necessary for those skilled in the art to provide a vehicle-mounted camera module test fixture in a timely manner that can meet the imaging effect test of the vehicle-mounted camera module at different installation positions in the vehicle. Utility Model Content

[0005] The purpose of this application is to provide a vehicle-mounted camera module test fixture that can meet the imaging effect testing requirements of the vehicle-mounted camera module at different installation positions in the vehicle.

[0006] To achieve the above objectives, the present application provides a vehicle-mounted camera module test fixture, comprising:

[0007] A fixing plate is provided with an adjustment seat, which is used for rotating connection of the vehicle-mounted camera module;

[0008] A plurality of retractable support rods, each of which is arranged on the side of the fixing plate away from the adjustment seat to support the fixing plate and the vehicle-mounted camera module, and each support rod is provided with a magnetic buckle bead on the end away from the fixing plate;

[0009] A plurality of base feet are provided, one end of each base foot is provided with a suction cup, and one end of each base foot away from the suction cup is provided with a buckle seat, and a magnetic buckle bead is buckled with the corresponding buckle seat to connect the support rod to the corresponding base foot.

[0010] In some embodiments, the vehicle-mounted camera module test fixture also includes a mounting seat, which includes a mounting plate, and first protrusions extend from both sides of the mounting plate in a direction away from the fixed plate to form an installation cavity for installing the vehicle-mounted camera module, and a second protrusion extends from the side of the mounting plate away from the first protrusion in a direction close to the fixed plate, and the second protrusion is rotatably connected to the adjustment seat.

[0011] In some embodiments, the adjustment seat includes two adjustment plates arranged opposite to each other, a receiving cavity for accommodating the second protrusion is formed between the two adjustment plates, and the second protrusion is rotatably connected to the two adjustment plates.

[0012] In some embodiments, the vehicle-mounted camera module test fixture further includes a fastener, which passes through the second protrusion and the two adjustment plates, and the fastener is used to fix the position of the second protrusion and the two adjustment plates after the position of the second protrusion relative to the two adjustment plates is adjusted.

[0013] In some embodiments, at least one of the two adjustment plates is provided with a scale for indicating the rotation angle of the mounting base, and the angle range of the scale is 0-180 degrees.

[0014] In some embodiments, the vehicle-mounted camera module test fixture further includes a telescopic drive assembly, one end of the telescopic drive assembly is hinged to the fixed plate, and the other end is hinged to the mounting seat, and the telescopic drive assembly is used to drive the mounting seat to rotate relative to the adjustment seat.

[0015] In some embodiments, the vehicle-mounted camera module test fixture further includes a remote control component, which is communicatively connected to the telescopic drive component to control the opening and closing of the telescopic drive component.

[0016] In some embodiments, each support rod includes a first rod body and a second rod body, and the first rod body is threadedly connected to the second rod body so that the length of the support rod can be controlled by telescoping.

[0017] In some embodiments, four connecting seats are provided on a side of the fixing plate away from the adjustment seat. The four connecting seats are respectively provided at four corners of the fixing plate, and the four connecting seats are used to connect four support rods respectively.

[0018] In contrast to the above-mentioned background technology, the vehicle-mounted camera module test fixture provided in the embodiments of the present application includes a fixed plate, a plurality of retractable support rods, and a plurality of base feet. The fixed plate is provided with an adjustment seat for rotatably connecting the vehicle-mounted camera module. Each support rod is provided on a side of the fixed plate away from the adjustment seat. Each support rod is used to support the fixed plate and the vehicle-mounted camera module. Each support rod is provided with a magnetic buckle bead at one end away from the fixed plate. Each base foot is provided with a suction cup at one end. Each base foot is provided with a buckle seat at the end away from the suction cup. The magnetic buckle bead snaps into place with the corresponding buckle seat to connect the support rod to the corresponding base foot.

For example, it can be set so that the two front support rods are shortened and the two rear support rods are extended, so that the entire device is in a downward-looking posture, or it can be set so that the two front support rods are extended and the two rear support rods are shortened, so that the entire device is in a backward-leaning posture. At the same time, the support rods are connected to the corresponding feet through magnetic buckles to facilitate multi-angle adjustment of the vehicle-mounted camera module. In addition, the vehicle-mounted camera module can also be rotated and adjusted relative to the adjustment seat.

[0020] The beneficial effects of the vehicle camera module test fixture configured in this way mainly include:

[0021] First, the suction cup installation method not only uses the principle of air compression to adsorb on the fixed surface inside the vehicle, providing a stable fixing method, but also allows the fixture installation position to be quickly switched according to test needs;

[0022] Secondly, the telescopic design of each support rod allows the product to be adjusted in size according to usage needs, providing flexibility in use and maximizing the utilization of space in the vehicle. In addition, when the product is not in use, it can be retracted to a smaller size for easy carrying and storage.

[0023] Third, the vehicle-mounted camera module can be rotated relative to the adjustment base to increase the freedom of camera movement, avoid obstacles, and improve the shooting field of view and object recognition accuracy;

[0024] Fourthly, the universal orientation of the magnetic buckle bead allows the angle of the corresponding support rod relative to the corresponding base to be adjusted arbitrarily. Furthermore, the magnetic attraction between the magnetic buckle bead and the buckle seat allows the corresponding support rod to stop at a preset angle relative to the corresponding base after rotating to the preset angle, thereby keeping the positions of the two relatively fixed, thus facilitating multi-angle adjustment of the vehicle-mounted camera module.

[0025] Fifth, through simple operations, the vehicle-mounted camera module can be adjusted in the horizontal and vertical installation positions in the vehicle, as well as the posture of the vehicle-mounted camera module, such as looking down or leaning back, so that it can quickly adapt to different usage scenarios and testing requirements.

[0035] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0037] Please see the attached Figure 1 To the attached Figure 3 The vehicle-mounted camera module test fixture provided in the embodiment of the present application includes a fixing plate 10, a plurality of retractable support rods 20 and a plurality of base feet 30.

[0038] An adjustment seat 11 is provided on the fixing plate 10 , and the adjustment seat 11 is used for rotational connection of the vehicle-mounted camera module.

[0039] Each support rod 20 is disposed on a side of the fixing plate 10 away from the adjustment seat 11 , and each support rod 20 is used to support the fixing plate 10 and the vehicle-mounted camera module.

[0040] One end of each foot 30 is detachably connected to the corresponding support rod 20 , and the other end of each foot 30 is provided with a suction cup 31 .

[0041] In order to facilitate the detachable connection of one end of each base foot 30 to the corresponding support rod 20 , one end of each base foot 30 may be connected to the corresponding support rod 20 by means of a magnetic buckle.

[0042] Specifically, each support rod 20 is provided with a magnetic buckle bead 21 at one end away from the fixed plate 10, and each base foot 30 is provided with a buckle seat 32 at one end away from the suction cup 31. The magnetic buckle bead 21 is buckled into the corresponding buckle seat 32 to connect the support rod 20 to the corresponding base foot 30.

[0043] The vehicle-mounted camera module test fixture provided in the embodiment of the present application adopts a four-corner fixing method, that is, the number of support rods 20 and base feet 30 are set to four, and the four base feet 30 all adopt the air compression principle. After finding the position where installation is required, the four corner points can be pressed down to compress the internal air out, making it easier to adsorb on the fixed surface.

[0044] In this way, each foot 30 of the clamp can be adsorbed on a fixed surface inside the car, such as the center console or windshield inside the car, through the suction cup 31, and each support rod 20 can adjust its own length through telescopic movement. For example, it can be set so that the two front support rods 20 are shortened and the two rear support rods 20 are extended, so that the entire device is in a downward-looking posture, or it can be set so that the two front support rods 20 are extended and the two rear support rods 20 are shortened, so that the entire device is in a backward-leaning posture. At the same time, each support rod 20 is connected to the corresponding foot 30 by a magnetic buckle 21 to facilitate multi-angle adjustment of the vehicle-mounted camera module. In addition, the vehicle-mounted camera module can also be rotated and adjusted relative to the adjustment seat 11.

[0045] With such a configuration, the installation method of adsorption by the suction cup 31 can not only utilize the principle of air compression to adsorb on the fixed surface in the vehicle, providing a stable fixing method, but also can quickly switch the installation position of the fixture according to the test needs. At the same time, the principle of the suction cup 31 compressing the air to generate adsorption force will not produce glue marks or scratches during the construction and use of the simulation equipment; the telescopic design of each support rod 20 can enable the product to adjust the overall size according to the use requirements, provide flexibility in use, and maximize the utilization rate of the space in the vehicle. In addition, when the product is not needed, it can be retracted to a smaller volume for easy carrying and storage; the vehicle-mounted camera module is rotated and adjusted relative to the adjustment seat 11, which increases the freedom of camera movement, can avoid obstacles, and improve the shooting field of view and object recognition accuracy; the vehicle-mounted camera module can be adjusted in the horizontal and vertical directions of the vehicle installation position, and the posture of the vehicle-mounted camera module can be adjusted, such as looking down or leaning back, through simple operation, so that it can quickly adapt to different usage scenarios and test requirements.

[0046] Not only that, one end of each base foot 30 can be connected to the corresponding support rod 20 by means of a magnetic buckle. On the one hand, the universal direction of the magnetic buckle bead 21 can be used to arbitrarily adjust the angle of the corresponding support rod 20 relative to the corresponding base foot 30. On the other hand, the magnetic attraction force of the magnetic buckle bead 21 and the buckle seat 32 can be used to stop at the preset angle after the corresponding support rod 20 rotates to the preset angle relative to the corresponding base foot 30, thereby keeping the positions of the two relatively fixed.

[0047] In addition, the use of spherical magnetic beads 21 can ensure that movement can be more convenient and quick, thereby ensuring that the four support rods 20 can adjust the angle and movement direction at any time on the same three-dimensional plane, ensuring that all obstructions are avoided during the simulation process.

[0048] The use of the above-mentioned vehicle-mounted camera module test fixture to install the vehicle-mounted camera module solves the technical problem that the traditional installation position of the vehicle-mounted camera module in the vehicle cannot be adjusted according to test needs, thereby failing to meet the current imaging effect test requirements.

[0049] In addition, after the current vehicle-mounted camera module is assembled, in order to facilitate testing, corresponding structural parts need to be designed to match the corresponding vehicle-mounted camera module. This requires waiting for mold opening or machining time, which can easily lead to a waste of project development time and cost.

[0050] In comparison, the vehicle-mounted camera module test fixture provided in the embodiment of the present application also includes a mounting seat 40, and the mounting seat 40 includes a mounting plate 41. Both sides of the mounting plate 41 extend a first protrusion 42 in a direction away from the fixing plate 10 to form an installation cavity for installing the vehicle-mounted camera module.

[0051] It can be seen that the mounting cavity formed by the mounting plate 41 and the first protrusions 42 on both sides thereof is U-shaped. The size of the U-shaped mounting cavity can be adjusted according to actual needs. For example, the width of the mounting plate 41 can be set to be wide enough to meet the installation of at least two vehicle-mounted camera modules, thereby completing the data acquisition of the two vehicle-mounted camera modules.

[0052] To facilitate securing the vehicle-mounted camera module, screw holes can be provided on the two first protrusions 42. This allows vehicle-mounted camera modules of different sizes to be secured to one side of the first protrusion 42. Compared to the traditional method of designing corresponding structural parts for each vehicle-mounted camera module, this arrangement does not require designing corresponding structural parts for the vehicle-mounted camera module. Instead, the corresponding vehicle-mounted camera module can be installed in the U-shaped mounting cavity, eliminating the time required for mold making and machining, saving project development time and production costs.

[0053] Furthermore, a second protrusion 43 extends from a side of the mounting plate 41 away from the first protrusion 42 in a direction close to the fixing plate 10 , and the second protrusion 43 is rotatably connected to the adjustment seat 11 .

[0054] It should be noted that the second protrusion 43 is located in the middle of the mounting plate 41. In this way, the second protrusion 43 is at the same distance from the two first protrusions 42. When the second protrusion 43 is rotatably connected to the adjustment seat 11, the mounting seat 40 and the vehicle-mounted camera module thereon rotate relative to the adjustment seat 11. The rotation can be ensured to be smooth, and the second protrusion 43 is evenly stressed, which is beneficial to ensuring the service life of the mounting seat 40.

[0055] In some embodiments, the adjustment seat 11 includes two adjustment plates 12 arranged opposite to each other. A receiving cavity for accommodating the second protrusion 43 is formed between the two adjustment plates 12 . The second protrusion 43 is rotatably connected to the two adjustment plates 12 .

[0056] The thickness of the second protrusion 43 is slightly smaller than the distance between the two adjustment plates 12 , so that the second protrusion 43 can rotate freely between the two adjustment plates 12 .

[0057] In some embodiments, damping plates can be added to the inner walls of the two adjustment plates 12, or to the two outer walls of the second protrusion 43, so that a damping force can be generated when the second protrusion 43 rotates relative to the two adjustment plates 12, so that the second protrusion 43 can stop at any position when it rotates to that position without adding additional fasteners.

[0058] In some embodiments, the vehicle-mounted camera module test fixture also includes a fastener, which passes through the second protrusion 43 and the two adjustment plates 12. The fastener is used to fix the position of the second protrusion 43 and the two adjustment plates 12 after the position of the second protrusion 43 relative to the two adjustment plates 12 is adjusted.

[0059] In some embodiments, at least one of the two adjustment plates 12 is provided with a scale for indicating the rotation angle of the mounting base 40 , and the angle range of the scale is 0-180 degrees.

[0060] Specifically, both adjustment plates 12 are arched structures, or in other words, the tops of the two adjustment plates 12 are set as semicircular surfaces, so that a scale can be set on the top of the adjustment plate 12, with the minimum unit being 1 degree, and a total of 180 degrees, wherein the zero scale line is located in the middle, and the angle is -20 degrees when rotated 20 degrees to the left from the zero scale line, and +20 degrees when rotated 20 degrees to the right from the zero scale line. After adjusting to the required angle, it can be fixed with a fixing bolt.

[0061] In this way, the pitch angle of the vehicle-mounted camera module in the car can be adjusted, with the minimum unit being 1 degree, and the one-way angle can meet 90-degree adjustment.

[0062] In some embodiments, the vehicle-mounted camera module test fixture also includes a telescopic drive assembly, one end of the telescopic drive assembly is hinged to the fixed plate 10, and the other end is hinged to the mounting seat 40, and the telescopic drive assembly is used to drive the mounting seat 40 to rotate relative to the adjustment seat 11.

[0063] For example, the telescopic drive component can be a telescopic electric cylinder or an oil cylinder. Through the telescopic movement of the telescopic electric cylinder or the oil cylinder, the mounting seat 40 can be driven to rotate relative to the adjustment seat 11 to realize the imaging effect test of the vehicle-mounted camera module at different pitch angles in the vehicle.

[0064] In some embodiments, the vehicle-mounted camera module test fixture further includes a remote control component, which is communicatively connected to the telescopic drive component to control the opening and closing of the telescopic drive component.

[0065] The remote control component can be a handheld remote controller, which sends a control signal to the telescopic drive component so that the telescopic drive component generates an extension and retraction movement after receiving the control signal.

[0066] In order to facilitate telescopic adjustment of each support rod 20, each support rod 20 includes a first rod body and a second rod body. The first rod body is threadedly connected to the second rod body so that the length of the support rod 20 can be controlled by telescopic adjustment.

[0067] For example, an external thread can be set at one end of the first rod body, and an internal threaded hole can be set at the end of the second rod body close to the first rod body, so that the end of the first rod body with the external thread is threadedly connected to the internal threaded hole of the second rod body, and the length of the corresponding support rod 20 can be adjusted according to actual test needs.

[0068] In this way, the four support rods 20 can be extended and retracted through threaded connections to facilitate finding the appropriate position for 3D simulation imaging. For example, the two front support rods 20 can be shortened and the two rear support rods 20 extended, so that the entire device is in a downward-looking posture. For another example, the two front support rods 20 can be extended and the two rear support rods 20 shortened, so that the entire device is in a backward-leaning posture, thereby achieving the greatest possible restoration and simulation of the 3D data setup within the limited space of the vehicle cabin.

[0069] In some embodiments, four connecting seats 13 are provided on the side of the fixing plate 10 away from the adjustment seat 11. The four connecting seats 13 are respectively provided at the four corners of the fixing plate 10. The four connecting seats 13 are used to connect the four support rods 20 respectively.

[0070] Of course, according to actual needs, the connection between the connecting seat 13 and the corresponding support rod 20 can also adopt the connection method of magnetic buckle beads 21 and buckle seats 32, so as to meet the universal adjustment of the support rod 20 relative to the fixed plate 10.

[0071] In summary, the vehicle camera module test fixture using the above configuration can bring the following beneficial effects:

[0072] 1. It can quickly and stably simulate the installation position of the vehicle camera module at any position, angle, and inclination in the front view of the vehicle, thereby meeting all 3D layout data.

[0073] 2. It can meet the requirements of online real-time imaging effects and road test record comparison of the same on-board camera module at different positions on the actual vehicle.

[0074] 3. The fixture can be installed without leaving any trace inside a competitor's vehicle, allowing for benchmarking against competitors in the same location and installation angle, ensuring consistency in basic benchmarking information.

[0075] 4. The magnetic buckle with opposite poles attracting each other can be recycled indefinitely without scratching the glass, and avoids the residual glue produced by 3M glue or tape.

[0076] 5. The installation position of the vehicle camera module can be adjusted in real time according to the 3D layout data.

[0077] 6. It can avoid the possibility of jitter and field of view deviation caused by recording videos with a handheld camera.

[0078] 7. It can record videos of multiple vehicle-mounted camera modules at the same time, making it easier to evaluate the imaging effects of the modules.

[0079] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0080] The above is a detailed introduction to the vehicle-mounted camera module test fixture provided by this application.

The description of the above embodiments is only used to help understand the solution and core ideas of this application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of this application, several improvements and modifications can be made to this application, and these improvements and modifications also fall within the scope of protection of this application.
