Description

Technical Field

[0001] The utility model relates to the technical field of sensor module detection and testing, in particular to a sensor module fixing fixture and a sensor module testing device. Background Art

[0002] Traditional sensor module testing generally involves clamping the sensor module itself with a fixture. This clamping structure usually uses two clamps to clamp the sensor module, which can only be used to clamp regular surfaces and cannot stably clamp irregular surfaces, which can easily result in large errors in the position each time the module is clamped. In addition, this clamping structure can only be achieved by the operator manually adjusting the angle of the fixture to adjust the direction and angle of the sensor module itself. This traditional method, when adjusting the angle, is manually adjusted, so angle errors are prone to occur even with reference objects. For tests that require stable placement in three-axis directions, such as sensor IMU (Inertial Measurement Unit) chip tests and other commonly used sensor module function tests, this traditional sensor module clamping method is difficult to meet the high-precision test requirements of these tests. Utility Model Content

[0003] The embodiments of the utility model provide a sensor module fixing fixture and a sensor module testing device to solve the problem in the prior art that the sensor module fixture is difficult to achieve precise position adjustment in three-axis directions, thereby being able to meet the testing requirements of various sensor modules.

[0004] According to one aspect of the utility model, a sensor module fixing fixture is provided, comprising:

[0005] The support member comprises a first placement surface, a second placement surface and a third placement surface, wherein the first placement surface, the second placement surface and the third placement surface are perpendicular to each other;

[0006] The mounting fixture is arranged on the support member, and the mounting fixture comprises a fixture pad for placing the sensor module, and the fixture pad is provided with a placement groove matching the shape of the sensor module.

[0007] The sensor module fixing fixture of the utility model has a support member with three mutually perpendicular placement surfaces. When the sensor module fixed on the installation fixture is adjusted in the three-axis direction, the support member can be placed stably on the desktop to achieve switching of the three-axis direction, thereby achieving precise adjustment of the orientation switching of the sensor module in the three-axis direction. At the same time, the fixture can achieve stable clamping of the sensor module through the fixture pad. Sensor modules of different structures can achieve corresponding placement groove structures by replacing the fixture pad to ensure that the sensor module can be stably clamped. Compared with the prior art method of clamping with two regular planes, it can ensure the stability of clamping and ensure that there will be no large error in the position of the sensor module each time it is clamped, which can be more conducive to the testing of sensor modules such as IMU chips.

[0008] In some embodiments, the mounting fixture also includes a mounting base and a mounting cover, the mounting cover is used to cover the mounting base, the fixture pad is installed on the mounting base, and a limiting structure is provided between the mounting cover and the mounting base, the limiting structure is used to limit the mounting cover to a state of covering the mounting base.

[0009] Therefore, through such an arrangement, the fixture pad can be stably clamped and fixed by using the mounting base and the mounting cover, and the sensor module can also be better clamped, thereby improving the stability of the sensor module when clamping.

[0010] In some embodiments, a mounting groove for mounting a fixture pad is provided on the mounting base.

[0011] Therefore, by such an arrangement, the clamp pad can be better installed on the mounting base, thereby improving the stability of the sensor module when clamping.

[0012] In some embodiments, a mounting positioning structure is provided between the mounting base and the fixture pad.

[0013] Therefore, through such a setting, the fixture pad can be better positioned when replaced, ensuring the fixation of the installation position of the fixture pad, so that the position of the sensor module will not have a large error each time it is clamped, which is more conducive to the testing of sensor modules such as IMU chips.

[0014] In some embodiments, the mounting positioning structure includes a positioning pin disposed on one of the mounting base and the fixture block, and a positioning pin hole disposed on the other of the mounting base and the fixture block.

[0015] Therefore, through such a setting, the positioning pins and the positioning pin holes can make it easier to align the fixture pad during installation, and combined with the coordination of the positioning pins and the positioning pin holes and the structure of the mounting grooves on the mounting base, it can ensure that the installation position and direction of the fixture pad are more accurate, so that there will be no large error in the position of the sensor module each time it is clamped, which is more conducive to the testing of sensor modules such as IMU chips.

[0016] In some embodiments, one end of the mounting cover is hinged to the mounting base, the limiting structure includes a snap clip hinged to the mounting base, and the mounting cover is provided with a slot that cooperates with the snap clip.

[0017] Therefore, through such an arrangement, the mounting cover can be restricted to a state where it covers the mounting base through the cooperation between the snap clip and the slot, thereby improving the stability of the clamp when clamping the sensor module.

[0018] In some embodiments, an elastic member for driving the snap clip to snap into the slot is provided between the snap clip and the mounting base.

[0019] Therefore, through such a configuration, the cooperation between the elastic member and the snap clip can be utilized to achieve self-locking of the installation cover, improve the limiting effect of the limiting structure on the installation cover, and improve the stability of the clamp when clamping the sensor module.

[0020] In some embodiments, it is characterized in that the support member is configured as a cube.

[0021] Therefore, through such an arrangement, the cube structure can be used to achieve stable placement of the sensor module in three-axis directions on the desktop.

[0022] In some embodiments, the support member is configured as a cubic frame.

[0023] Therefore, by such an arrangement, the structural weight and structural cost of the support member can be reduced, and the fatigue of the operator when operating the switching of the three-axis directions can be reduced.

[0024] In some embodiments, the support member includes two square frame side panels arranged in parallel, and a frame cross bar connected between the two frame side panels, and the mounting fixture is arranged on the frame cross bar.

[0025] Therefore, through such an arrangement, the two square frame side panels can be used to achieve the stable placement of the overall support member in the three-axis direction, and the frame cross bar can be used to effectively reduce the overall structural weight, and it can also serve as an installation structure for the installation fixture.

[0026] According to another aspect of the present invention, a sensor module testing device is provided, comprising the sensor module fixing fixture of the first aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0046] Figure 1 The overall structure diagram of the sensor module fixing fixture of an embodiment of the utility model is schematically shown. Figure 1 As shown, the sensor module fixing fixture of the present invention includes a support member 1 and a mounting fixture 2, wherein the mounting fixture 2 is arranged on the support member 1, so as to support the placement of the mounting fixture 2 by using the support member 1. The support member 1 is provided with a first placement surface 14, a second placement surface 15 and a third placement surface 16 (such as Figure 1The gray surface framed by the dotted line only represents the placement surface and does not mean that there must be a physical component). The first placement surface 14, the second placement surface 15 and the third placement surface 16 are planes where the structures arranged on the support member 1 are located, and they can all be used to place the support member 1 stably on a plane such as a desktop. The first placement surface 14, the second placement surface 15 and the third placement surface 16 are perpendicular to each other, so that the support member 1 can be placed in three mutually perpendicular planar directions through the first placement surface 14, the second placement surface 15 and the third placement surface 16, so that the support member 1 can be placed stably in three-axis directions and switched at will. The mounting fixture 2 is a fixture assembly for installing the sensor module 6. The mounting fixture 2 is arranged on the support member 1. It can be specifically arranged inside the support member 1 or outside the support member 1, as long as it does not affect the placement of the support member 1 using the first placement surface 14, the second placement surface 15 and the third placement surface 16. The mounting fixture 2 is provided with a fixture pad 3 for placing the sensor module 6, and the fixture pad 3 is provided with a placement groove 31 for matching the shape of the sensor module 6, so that when the sensor module 6 is installed on the mounting fixture 2, the sensor module 6 will fit with the placement groove 31 on the fixture pad 3, so that the sensor module 6 can be stably clamped to ensure that there will be no large error in the position of the sensor module 6 each time it is clamped. When it is necessary to clamp other sensor modules 6, the corresponding sensor modules 6 can be adapted by replacing the fixture pad 3 to ensure that different sensor modules 6 can be stably clamped. In conjunction with the support 1, the universal sensor module fixture of the utility model can be applied to the testing of various sensor modules 6 such as IMU chips.

[0047] The shape of the support member 1 can be set to various regular or irregular shapes, as long as the support member 1 has a first placement surface 14, a second placement surface 15 and a third placement surface 16. For example, the support member 1 can be a regular structure such as a cube or an octahedron, or an irregular structure such as a round body with a first placement surface 14, a second placement surface 15 and a third placement surface 16. For example, referring to Figure 1 and Figure 3 As shown, in Figure 1 and Figure 3 In the embodiment shown, the support member 1 is specifically configured as a rectangular parallelepiped structure, and the rectangular parallelepiped structure has three sets of mutually perpendicular planes, thereby forming a first placement surface 14, a second placement surface 15 and a third placement surface 16. As a possible embodiment, refer to Figure 1 and Figure 2As shown, the support member 1 can also be set as a rectangular frame structure. Setting the support member 1 as a rectangular frame structure can help reduce the weight of the entire support member 1, reduce the fatigue of the operator when operating the switching of the three-axis directions, and ensure the stability of the support member 1 when it is placed. At the same time, the structure of the frame can also facilitate the installation of the fixture 2 set inside the support member 1, so that it is not easy to affect the placement of the support member 1. At the same time, such a design can also make the sensor module 6 fixed on the support member 1 for flip test. The connecting line of the sensor module 6 can be connected at the hollow position on any side of the support member 1, so that the support member 1 can be placed in any direction without pressing the connecting line of the sensor module 6, which will not affect the stable placement of the support member 1 and the high-precision angle requirement of the sensor module 6 when it is placed. For example, refer to Figure 2 As shown, in Figure 2 In the illustrated embodiment, the support member 1 includes two square frame side panels 11 arranged in parallel, and a frame cross bar 12 connected between the two frame side panels 11. The frame side panels 11 are provided with screw mounting holes 13. Two frame cross bars 12 are also arranged in parallel and are mounted at the screw mounting holes 13 of the frame side panels 11 by screws. The frame cross bar 12 is also provided with a plurality of screw mounting holes 13. The mounting fixture 2 can be mounted at the screw mounting holes 13 on the frame cross bar 12 by screws, so as to install the mounting fixture 2 on the frame cross bar 12, thereby enabling the mounting fixture 2 to be arranged inside the support member 1, so as to avoid the mounting fixture 2 affecting the stability of the support member 1. In other possible embodiments, the frame side panels 11 can be arranged as a closed non-hollow panel structure, and the frame cross bar 12 can also be arranged as a closed non-hollow panel structure. Specifically, as Figure 3 As shown, in Figure 3 In the embodiment shown, the support member 1 includes two parallel square side panels 17 and a transverse panel 18 connected between the two side panels 17. The mounting fixture 2 can be mounted on one of the transverse panels 18. The mounting method of the side panels 17 and the transverse panel 18 and the mounting method of the mounting fixture 2 can refer to the above Figure 1 and Figure 2 Alternatively, the side panels 17 and the transverse panels 18 may be integrally formed structures, and the mounting fixture 2 may be fixed to one of the transverse panels 18 by welding or the like.

[0048] The mounting fixture 2 may include a mounting base 21 and a mounting cover 22. The fixture pad 3 is specifically arranged on the mounting base 21. The mounting cover 22 and the mounting base 21 have an open state and a closed state. Figure 6 and Figure 7 As shown, in Figure 6 and Figure 7In the illustrated embodiment, when the mounting cover 22 and the mounting base 21 are in a covering state, the sensor module 6 can be stably clamped on the fixture pad 3, so that the overall mounting fixture 2 can stably clamp the sensor module 6; when the mounting cover 22 and the mounting base 21 are in an open state, the sensor module 6 can be removed from the fixture pad 3. A limiting structure is provided between the mounting cover 22 and the mounting base 21, and the limiting structure is used to limit the mounting cover 22 and the mounting base 21 to a covering state. The connection between the mounting cover 22 and the mounting base 21 can be a structure connected only by a limiting structure. For example, the mounting cover 22 and the mounting base 21 are completely separated. When the mounting cover 22 is removed from the mounting base 21, the mounting cover 22 and the mounting base 21 are in an open state. When the mounting cover 22 is covered on the mounting base 21, the mounting cover 22 and the mounting base 21 are in a closed state, and the connection, fixation and separation between the mounting cover 22 and the mounting base 21 are achieved by the limiting structure. The connection between the mounting cover 22 and the mounting base 21 can also be set as that one end of the mounting cover 22 is hinged to the mounting base 21, so that the mounting cover 22 can be rotatably moved on the mounting base 21, and the state between the mounting cover 22 and the mounting base 21 will switch between the open state and the closed state as the mounting cover 22 rotates, and the mounting cover 22 can be limited to the state of covering the mounting base 21 by the limiting structure. Specifically, the limiting structure can be set to a snap-on structure, a spring-on structure, etc. commonly used in the prior art, and it only needs to ensure that the installation cover 22 can be limited to a state of covering the installation base 21.

[0049] For example, refer to Figure 4 As shown, in Figure 4In the embodiment shown, one end of the mounting cover 22 is hinged to the mounting base 21, so that the mounting cover 22 can be rotated to open and rotated to cover. The limiting structure specifically includes a snap clip 41 hinged to the mounting base 21, and a slot 42 provided on the outer side of the mounting cover 22 and cooperating with the snap clip 41. The hinge between the mounting cover 22 and the mounting base 21 can be achieved by providing hinge ears on the mounting cover 22 and the mounting base 21, and connecting them by a hinge shaft. Similarly, the hinge between the snap clip 41 and the mounting base 21 can also be achieved by providing hinge ears on the mounting cover 22 and the snap clip 41, and connecting them by a hinge shaft. The snap clip 41 is provided with a snap head 43 bent back, and the snap clip 41 is hinged to the mounting base 21, so that it can be switched between a snap-on state to the slot 42 and a separated state away from the slot 42. When the installation cover 22 is rotated to cover the installation base 21, the snap clip 41 can be rotated so that the snap head 43 on the snap clip 41 is snapped into the slot 42 on the installation cover 22, so as to limit the installation cover 22 in the covered state. As a possible embodiment, an elastic member can be provided between the snap clip 41 and the installation base 21, and the elastic member is used to drive the snap clip 41 to snap to the slot 42, so that the limiting structure can stably limit the opening of the installation cover 22. As another possible embodiment, an elastic member can also be provided between the installation cover 22 and the installation base 21, and the elastic member is used to drive the installation cover 22 to rotate and open, so that when the limit on the installation cover 22 is released, the installation cover 22 can automatically rotate and open under the action of the elastic member, so that the user can replace the sensor module 6 that needs to be tested. The elastic member arranged between the snap clip 41 and the mounting base 21 and the elastic member arranged between the mounting cover 22 and the mounting base 21 can be implemented by a torsion spring. The specific installation of the torsion spring can be set with reference to the relevant description in the prior art, and this part of the content will not be expanded here.

[0050] For the installation between the fixture pad 3 and the mounting base 21, the mounting base 21 may be provided with a mounting groove 23 for installing the fixture 2 pad, and the fixture pad 3 is installed in the mounting groove 23 to be installed on the mounting base 21. As a possible implementation, an installation positioning structure may also be provided between the mounting base 21 and the fixture pad 3. The installation positioning structure is a structure for aligning the installation positioning between the fixture pad 3 and the mounting base 21, so that the fixture pad 3 can be better positioned when the fixture pad 3 is replaced, ensuring the fixing of the installation position of the fixture pad 3, so that the position of the sensor module 6 will not have a large error each time it is clamped, so as to be more conducive to the testing of the sensor module 6 such as the IMU chip. Among them, the installation positioning structure can be set to fully set the inner side of the mounting groove 23 of the mounting base 21 to be inclined inward, and the fixture pad 3 is set to a wedge-shaped structure matching the structure of the mounting groove 23, so that the fixture pad 3 can be more accurately installed in the mounting groove 23. The installation and positioning structure can also be configured to achieve installation and positioning through structures commonly used in the prior art such as bumps and grooves. Figure 4 and Figure 5 As shown, in Figure 4 and Figure 5 In the embodiment shown, the installation positioning structure between the installation base 21 and the fixture pad 3 can be configured to include a positioning pin 51 and a positioning hole 52. The positioning pin 51 is arranged on the bottom surface of the installation groove 23, and the positioning hole 52 is arranged on the bottom surface of the fixture pad 3. The positioning pin 51 and the positioning hole 52 are provided with at least one set, for example Figure 4 There are two groups of positioning pins 51, and their positions in the mounting groove 23 and the clamp pad 3 are different, and one group of positioning pins 51 is close to Figure 4 The upper side of the mounting base 21 shown in the figure, and the other group Figure 4 A certain interval is provided between the lower sides of the mounting base 21 shown, so that the upper and lower sides of the clamp pad 3 can be better distinguished during installation. When the clamp pad 3 is installed in the mounting groove 23, it is only necessary to align the positioning hole 52 with the positioning pin 51 to complete the precise alignment of the installation position of the clamp pad 3, so that the clamp pad 3 can be more accurately installed in the mounting groove 23. In some other possible embodiments, the positioning pin 51 and the positioning hole 52 can be arranged in opposite positions, that is, the positioning hole 52 can be arranged on the mounting groove 23, and the positioning pin 51 can be arranged on the clamp pad 3. Such an arrangement can also improve the installation accuracy of the clamp pad 3.

[0051] When the sensor module fixing fixture of the utility model is in use, it is only necessary to replace the fixture pad 3 on the installation fixture 2 according to the sensor module 6 to be tested. When replacing the fixture pad 3, first press the snap clip 41 to make the snap clip 41 away from the slot 42 on the installation cover 22, then rotate the installation cover 22 to make the installation cover 22 and the installation base 21 in an open state, so as to take out the original fixture pad 3, and then make the positioning hole 52 of the fixture pad 3 corresponding to the sensor module 6 to be tested correspond to the positioning pin 51 on the installation base 21, install the fixture pad 3 on the installation base 21, and place the sensor module 6 on the fixture pad 3, and then rotate the installation cover 22 to cover it, use the snap clip 41 to buckle the slot 42 to limit the installation cover 22 in the covered state, and complete the installation of the sensor module 6. Figure 8 Status shown. Fig. 9 and Fig.10 It is a schematic diagram of the utility model when clamping different sensor modules 6. When the three-axis direction of the sensor module 6 needs to be switched, the operator can rotate the support member 1 to switch the orientation of the sensor module 6 in the three-axis direction, so as to facilitate the testing of the sensor module 6 such as the IMU chip.

[0052] The sensor module fixing fixture of the utility model can make the sensor module 6 fixed on the mounting fixture 2 adjust the three-axis direction (such as Figure 1 and Figure 3 When the position orientation is adjusted on the x-axis, y-axis, and z-axis directions (as shown in the figure), the three-axis directions can be switched by placing the support 1 stably on the desktop, thereby realizing precise adjustment of the orientation switching of the three-axis directions of the sensor module 6. At the same time, the fixture can realize stable clamping of the sensor module 6 through the fixture pad 3. Sensor modules 6 with different structures can be adapted to the clamping of a variety of different sensor modules 6 by replacing the fixture pad 3 to ensure that the sensor module 6 can be stably clamped. Compared with the prior art method of clamping with two regular planes, it can ensure the stability of the clamping and ensure that there will be no large error in the position of the sensor module 6 each time it is clamped, which can be more conducive to the testing of sensor modules 6 such as IMU chips.

[0053] The present utility model also provides a sensor module test device, including the sensor module fixing fixture in the above-mentioned embodiment. The sensor module test device is provided with a sensor module fixing fixture, which can realize accurate switching of the orientation of the sensor module 6 in the three-axis direction during the test. At the same time, the stability of the fixture when clamping the sensor module 6 is greatly improved, ensuring that there will be no large error in the position of the sensor module 6 each time it is clamped, and can be applicable to various tests of sensor modules 6 such as IMU chips. The sensor module test device of the present utility model can also include computer equipment, mobile communication equipment (such as smart phones, multimedia phones, functional phones, etc.), servers or other electronic devices with data interaction functions, and these electronic devices can be provided with interfaces to connect with the connecting lines of the sensor module 6. The electronic devices can also be installed with test programs to realize data transmission and realize testing of the sensor module 6.
