Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there can be a central component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0028] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this application and in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this application includes any and all combinations of one or more of the related listed items.

[0029] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0030] In one embodiment of the present application, Figure 1 and Figure 2 As shown, the tilt test platform 100 includes a base 10, two sliding seats 20, a platform structure 30 and a driving assembly 40, wherein one sliding seat 20 is slidably connected to the base 10 along a first direction, and the other sliding seat 20 is slidably connected to the base 10 along a second direction, the first direction is a horizontal direction, and the second direction is tilted upward; the base 10 of the platform structure 30 is rotatably connected to the two sliding seats 20; the driving assembly 40 is connected to the base 10, and the output end of the driving assembly 40 is connected to one of the sliding seats 20; the driving assembly 40 is used to drive the sliding seat 20 to move between a first position and a second position, when the sliding seat 20 is in the first position, the platform structure 30 is horizontally arranged; when the sliding seat 20 is in the second position, the platform structure 30 is vertically arranged.

[0031] In this embodiment, the tilt test platform 100 includes two sliding seats 20, and the two sliding seats 20 are slidably connected to the base 10 in different directions. One of the sliding seats 20 is slidably connected to the base 10 in a horizontal direction (defined as a first direction), and the other sliding seat 20 is slidably connected to the base 10 in an upward tilting direction (defined as a second direction). The base 10 of the platform structure 30 and the two sliding seats 20 are connected in a rotating manner, so that the platform can tilt while the sliding seat 20 moves, thereby achieving a continuous change in posture. The driving assembly 40 is responsible for providing power, driving the sliding seat 20 to move between the first position and the second position, driving the platform structure 30 to tilt in a large range from horizontal to vertical, and accurately adjusting any intermediate angle. That is, the present application can be adjusted to different inclination angles to complete different tests after installing and fixing the test piece 200, without repeatedly disassembling and assembling the test piece 200, thereby improving the detection efficiency. Furthermore, by slidingly connecting the two sliding seats 20 in different directions, the platform structure 30 can be tilted over a large range from horizontal to vertical, rather than directly lifting the tilting test platform 100 by the driving member, thereby improving the stability of the tilting process of the platform structure 30 and the accuracy of the tilting angle, thereby improving the accuracy of the detection results.

[0032] For the convenience of distinction, the sliding seat 20 that slides in the first direction is defined as the first sliding seat 20a, and the sliding seat that slides in the second direction is defined as the second sliding seat 20b. The output end of the driving assembly 40 is connected to the first sliding seat 20a to drive the first sliding seat 20a to slide in the first direction; the tilting test platform 100 also includes a locking mechanism, which is used to lock the second sliding seat 20b and the base 10. The driving assembly 40 provides a driving force in the horizontal direction for the first sliding seat 20a, drives the first sliding seat 20a to move in the horizontal direction, thereby driving the second sliding seat 20b to move in the second direction. For example, the driving assembly 40 drives the first sliding seat 20a to move rightward, thereby driving the second sliding seat 20b to move obliquely to the upper right, so that the platform gradually tilts. After the platform structure 30 is tilted into place, the locking mechanism locks the relative position between the second sliding seat 20b and the base 10 to prevent accidental movement caused by external interference or internal vibration, thereby ensuring the accuracy and stability of the test.

[0033] After the locking mechanism is unlocked, the driving assembly 40 can drive the first sliding seat 20 a to move again to adjust the tilt angle of the platform structure 30 .

[0034] Among them, see Figures 2 to 4 , the drive assembly 40 comprises a motor 41, a screw rod 42 and a screw sleeve 43, the motor 41 is connected to the base 10, the screw sleeve 43 is connected to the first sliding seat 20a, the screw rod 42 is rotatably mounted on the base 10, the output end of the motor 41 is connected to the screw rod 42, and the screw sleeve 43 is threadedly connected to the screw rod 42. The output end of the motor 41 is connected to the screw rod 42, so the rotation of the motor 41 will drive the screw rod 42 to rotate together, and when the screw rod 42 rotates, the thread thereon will mesh with the thread inside the screw sleeve 43. This meshing action enables the screw sleeve 43 and the first sliding seat 20a to move linearly along the length direction of the screw rod 42 so as to drive the platform structure 30 to tilt, and the angle of the platform structure 30 tilting is determined by the terminal position of the first sliding seat 20a. The transmission of the screw rod 42 and the screw sleeve 43 is conducive to reducing the error in the transmission process, improving the accuracy of the terminal position of the first sliding seat 20a, thereby accurately controlling the tilt angle of the platform structure 30.

[0035] The motor 41 can be a stepper motor 41 or a servo motor 41 with a brake, that is, the motor 41 has a self-locking function; the threaded connection between the screw rod 42 and the screw sleeve 43 also has a certain self-locking ability. When the screw sleeve 43 moves on the screw rod 42 and reaches a predetermined position, even if the motor 41 stops working, the screw sleeve 43 will remain in the current position due to the friction and preload of the thread, and it is not easy to slip; combined with the locking effect of the locking mechanism on the second sliding seat 20b, the platform structure 30 can stably maintain its position after reaching the preset angle, thereby improving the accuracy and stability of the platform posture. The screw rod 42 can be mounted on the base 10 through two bearing seats to form a stable support structure. The bearing seat can stably support the screw rod 42 and withstand various forces and torques in the transmission process, ensuring the stability and accuracy of the rotation of the screw rod 42. The output shaft of the motor 41 can be connected to the screw rod 42 through a coupling, a reducer, a universal joint, etc., to ensure the reliability and accuracy of the connection.

[0036] In other embodiments, the driving assembly 40 may also include a motor 41, a rotating shaft and a traction rope, one end of the traction rope is connected to the first sliding seat 20a, and the other end is connected to the rotating shaft, and the rotating shaft is rotatably mounted on the base 10. The motor 41 drives the rotating shaft to rotate, so that the traction rope is wound around the rotating shaft, driving the first sliding seat 20a to move rightward. When the platform structure 30 tilts, it has a component force obliquely directed to the lower left, that is, it can tighten the traction rope, thereby ensuring that the first sliding seat 20a can move stably, and when the first sliding seat 20a drives the platform structure 30 to reach a preset tilt angle, it is locked by the locking mechanism.

[0037] In other embodiments, the second sliding seat 20 b may also be driven by the driving assembly 40 , and the locking mechanism is used to lock the first sliding seat 20 a , which is not limited in the present application.

[0038] In one embodiment, the first sliding seat 20a and the second sliding seat 20b can be installed on the base 10 through a guide rail and slider structure. The base 10 is provided with a first slide rail 51 extending along the first direction, and a first slider 53 is provided at the bottom of the first sliding seat 20a, and the first slider 53 is slidably connected to the first slide rail 51; the base 10 is provided with a second slide rail 52 extending along the second direction, and a second slider 54 is provided at the bottom of the second sliding seat 20b, and the second slider 54 is slidably connected to the second slide rail 52. The design of the guide rail and slider structure makes the sliding process of the first sliding seat 20a and the second sliding seat 20b smoother, reduces vibration and noise, and improves the stability of the system.

[0039] The number of the first guide rails can be two, and the two first guide rails can more evenly distribute the weight of the first sliding seat 20a and its load, thereby reducing the risk of deformation or damage caused by excessive force on a single point. At the same time, the double guide rail design also improves the stability of the sliding seat 20 during movement, reducing the deviation or shaking caused by lateral force or unbalanced load.

[0040] Similarly, the number of the second guide rails may also be two.

[0041] Please refer again Figures 1 to 3 The base 10 includes a bottom plate 11 and two support plates 12. The two support plates 12 are arranged opposite to each other on the bottom plate 11 to form a two-side support structure of the base 10. The first slide rail 51 is arranged on the bottom plate 11. The support plate 12 has a mounting surface 121 extending along the second direction. The mounting surfaces 121 of the two support plates 12 are each provided with a second slide rail 52. The projection of the platform structure 30 and the first slide rail 51 along the first direction is located between the two support plates 12, that is, the space between them provides sufficient movement and adjustment space for the platform structure 30, the first slide rail 51 and possible other moving parts. The platform structure 30 will not interfere with the support plate 12 during movement and tilting, thereby ensuring the smooth operation of the system.

[0042] The bottom plate 11 provides a stable support surface, and the screw rod 42 is mounted on the bottom plate 11. The two ends of the mounting beam are respectively connected to the two support plates 12, forming a stable structure across the upper part of the base 10. This design not only enhances the overall rigidity of the base 10, but also provides a stable platform for the installation of the motor 41.

[0043] In the case of a guide rail sliding structure, the locking structure can be a locking component of the slider. For example, a locking screw, a cylinder clamp, a clamp linear guide lock, etc. The slider with a locking component is a standard part, and this application does not provide a detailed description of this. In addition, the first slider 53 and the second slider 54 can both be sliders with locking components, or only the second slider 54 can be a slider with a locking component, and this application does not limit this.

[0044] The connection structure of the first sliding seat 20a and the second sliding seat 20b is the same, and the difference is only in the length of the first sliding seat 20a and the second sliding seat 20b. The present application takes the structure of the first sliding seat 20a as an example for explanation.

[0045] A limit block may be provided at the end of the first slide rail 51 , and the limit block is used to limit and stop the first slide block 53 to prevent the first slide block 53 from falling out.

[0046] Mutually coordinated counter-radiation sensors can be provided on the base 10 and the first sliding seat 20a, one of which is provided with a transmitting end and the other with a receiving end. When the first sliding seat 20a slides until the transmitting end is aligned with the receiving end, the platform structure 30 is in a horizontal position. Since the inclination angle in the second direction is determined, the moving distance of the first sliding seat 20a and the tilting angle of the platform structure 30 have a strict corresponding relationship. Therefore, the tilting angle of the platform structure 30 can be determined by detecting the moving distance of the first sliding seat 20a by means of a motor 41, laser ranging or other methods. Of course, an inclination sensor can also be provided at the bottom of the platform structure 30, and this application does not limit this.

[0047] In one embodiment, see Figure 2 , Figure 3 , Figure 5 and Figure 6 The sliding seat 20 includes a main body 21, a mounting plate 22 and a reinforcing plate 23; the main body 21 includes two side plates 211 arranged opposite to each other and a top plate 212 connected to the top of the two side plates 211; a mounting plate 22 is respectively provided at both ends of the bottom of the two side plates 211, and the mounting plate 22 is at least partially exposed to connect the first slider 53; a plurality of reinforcing plates 23 are spaced apart between the two side plates 211.

[0048] The main body 21 is composed of two side panels 211 arranged opposite to each other, which provide a basic support frame for the sliding seat 20. The material and thickness of the side panels 211 are usually determined according to the weight and force required to be carried to ensure the stability and durability of the sliding seat 20. The flat plate structure connected to the top of the two side panels 211 is called the top, which is used to reinforce the integrity of the sliding seat 20 and provide an interface for installing other components (such as the base 10 of the platform structure 30). A mounting plate 22 is provided at each end of the bottom of the two side panels 211. These mounting plates 22 are key components for connecting the sliding seat 20 with the slide rail, responsible for fixing the sliding seat 20 on the slide rail and allowing it to slide along the slide rail. The mounting plate 22 is at least partially exposed so as to be connected to the first slider 53 (or other types of connectors). Usually, the mounting plate 22 is provided with a groove, hole or thread structure that matches the slider to ensure a tight connection between the two.

[0049] like Figure 6 As shown, a plurality of reinforcing plates 23 are arranged between the two side plates 211. These reinforcing plates 23 and the side plates 211 together form a mesh or grid structure, which enhances the rigidity and stability of the sliding seat 20. The main function of the reinforcing plates 23 is to disperse the stress and deformation generated when the sliding seat 20 bears weight and is subjected to external forces. By reasonably setting the number, position, size, shape and other parameters of the reinforcing plates 23, the bearing capacity and anti-deformation ability of the sliding seat 20 can be significantly improved.

[0050] The density of the reinforcing plate 23 in the area corresponding to the mounting plate 22 is greater than the density of the reinforcing plate 23 in the remaining areas. When the sliding seat 20 bears weight or is subjected to external forces, these forces and stresses will be concentrated in certain areas of the sliding seat 20, especially the parts connected to the mounting plate 22 and the side plate 211. The presence of the reinforcing plate 23 can disperse these concentrated stresses to a larger area, thereby reducing the local stress peak and avoiding the material from being damaged due to excessive stress. The overall rigidity of the sliding seat 20 is enhanced so that it can better resist external deformation.

[0051] An L-shaped reinforcement structure may also be provided between the mounting plate 22 and the side plate 211 , with one arm of the L-shaped reinforcement structure being connected to the side plate 211 , and the other arm being connected to the mounting plate 22 .

[0052] See also Figure 2 , Figure 7 and Figure 8 The bottom of the platform structure 30 is provided with an articulated seat 31, which is located at the bottom of the platform structure 30 and is a key component connecting the platform structure 30 and the sliding seat 20. It not only bears the weight of the platform structure 30, but is also connected to the mounting seat 24 through a pivot 32, allowing the platform structure 30 to rotate. The sliding seat 20 is provided with two mounting seats 24, and the articulated seat 31 is located between the two mounting seats 24, and the articulated seat 31 and the two mounting seats 24 are rotatably connected through the pivot 32. The pivot 32 is a key component connecting the articulated seat 31 and the two mounting seats 24. The pivot 32 not only plays a supporting role, but also serves as a rotation axis to allow the articulated seat 31 to rotate around it.

[0053] Each component (including the hinge seat 31, the mounting seat 24, the pivot 32 and the sliding seat 20) needs to have sufficient load-bearing capacity to withstand the weight of the platform structure 30 and the equipment thereon and the forces and moments generated during rotation.

[0054] The mounting seat 24 includes a seat body 241 and a cover plate 242. The seat body 241 is the main supporting structure of the mounting seat 24 and is usually made of a sturdy and durable material, such as cast iron or alloy steel. The mounting channel 243 provided on the seat body 241 is used to accommodate and support the pivot 32, ensuring that the pivot 32 can rotate smoothly and withstand the weight and torque from the platform structure 30. The seat body 241 is provided with a mounting channel 243, and the first bearing 244 and the second bearing 245 are respectively provided at the openings at both ends of the mounting channel 243. The two bearings are used to support and position the pivot 32 to reduce friction and wear. The selection of the bearing should be determined based on factors such as the size, rotation speed, load and working environment of the pivot 32 to ensure that it has good durability and reliability. The cover plate 242 is arranged on the opening outside the installation channel 243, and part of the cover plate 242 extends into the installation channel 243 to press against the outer ring of the first bearing 244; the cover plate 242 can close the opening of the installation channel 243, thereby facilitating the filling of lubricating grease inside the installation channel 243, and can also serve as a limit stop for the first bearing 244.

[0055] Steps can be formed at both ends of the installation channel 243, the outer ring of the first bearing 244 is clamped between the step and the cover plate 242, and one side of the second bearing 245 is pressed against the step. The first bearing 244 and the second bearing 245 are used together to effectively share the load and reduce the wear and damage rate of the bearings.

[0056] The pivot 32 can adopt a multi-section step shaft design connected in sequence, wherein the first-step shaft passes through the hinge seat 31 and is key-connected to the hinge seat 31; wherein the first-step shaft passes through the first bearing 244 and the second bearing 245 arranged on the same mounting seat 24 in sequence, and a retaining ring is provided at the end of the pivot 32 to limit the inner ring of the first bearing 244 to prevent the first bearing 244 and the pivot 32 from loosening; one of the shaft steps of the pivot 32 presses against the inner ring of the second bearing 245, which helps to further fix the position of the second bearing 245 and reduce the axial clearance of the second bearing 245, thereby improving the supporting force and stability of the bearing.

[0057] In one embodiment, please refer again to Figure 2 and Figure 7 The tilt test platform 100 further includes an auxiliary support assembly 60, which includes a connection seat 61 and an adjustment rod 62. The connection seat 61 is rotatably connected to the platform structure 30, and the adjustment rod 62 is threadedly connected to the connection seat 61. A foot cup 63 is provided at the bottom end of the adjustment rod 62. The auxiliary support assembly 60 is located between the two sliding seats 20. When the platform tilts, the length of the adjustment rod 62 can be adjusted to achieve stable support of the platform structure 30 at different heights and angles.

[0058] The adjusting rod 62 and the connecting seat 61 are connected by a threaded connection, and this connection method makes the telescopic adjustment of the adjusting rod 62 simple and accurate. The user only needs to rotate the adjusting rod 62 to adjust its length to meet different support requirements. The foot cup 63 is in direct contact with the base 10 and provides support. The design of the foot cup 63 usually has anti-skid, shock-absorbing and other functions to ensure that the platform structure 30 can remain stable during the tilting or adjustment process and reduce damage to the ground. The foot cup 63 is usually made of wear-resistant and durable materials, such as rubber, nylon, etc. These materials not only have good anti-skid properties, but also can absorb vibration and impact to a certain extent, thereby improving the stability and service life of the platform.

[0059] Auxiliary support components 60 can be provided on both the front and rear sides of the platform structure 30 to better ensure that the platform structure 30 maintains a better balance during the tilting or adjustment process. The double-sided support is also conducive to reducing the risk of shaking and tilting, and improving the stability of the platform. It can be understood that before the platform structure 30 is adjusted to be horizontal, the foot cup 63 adjustment rod 62 needs to be retracted to avoid damage to the tilting test platform 100 caused by motion interference.

[0060] It should be noted that a positioning fixture 300 may be provided on the platform structure 30 to position and fix the test piece 200.
