Description

Technical Field

[0001] The invention relates to the technical field of trolley testing, and in particular to a trolley testing device for large-angle zero-gravity seat testing. Background Art

[0002] The large-angle zero-gravity seat is a seat specially designed to enhance the passenger experience, improve riding comfort, and reduce body stress and fatigue. The design of this seat is inspired by the weightlessness experienced by astronauts in the aerospace field. The zero-gravity seat refers to the relaxed posture of the human body in a weightless state, and provides a more natural and comfortable sitting posture by optimizing posture and support points.

[0003] In traditional car seats, long periods of sitting often cause certain parts of the body to bear too much pressure, which in turn causes fatigue and discomfort. The zero-gravity seat is designed with a large angle tilt, allowing the passenger's torso and legs to form a posture similar to lying. This posture evenly distributes the weight of the body, reduces the pressure on the spine, waist and buttocks, and can reduce the health risks caused by long-term sitting in traditional car seats, such as pain in the waist and buttocks, and varicose veins. However, there are large differences in the posture and performance of zero-gravity seats and traditional seats, and the test standards are currently imperfect. Using the existing track trolley system, it is difficult to more comprehensively reflect the relevant performance of zero-gravity seats. Therefore, the field of trolley test technology needs to propose a trolley test device that can more realistically and comprehensively test and reflect the performance of large-angle zero-gravity seats.

[0035] See attached Figure 1-3The present application provides a trolley test device for testing a large-angle zero-gravity seat 7, including a trolley mechanism 1 and a trolley track 2.

The second trolley 102 and the second driving mechanism 106 are configured to be rotatably connected, the trolley track 2 includes a track base 201, a first track 202 and a second track 203, the first track 202 and the second track 203 are arranged on the upper side of the track base 201, the first driving mechanism 105 is connected with the first track 202, the second driving mechanism 106 is connected with the second track 203, and the first track 202 and the second track 203 are arranged in parallel without overlapping. The first driving mechanism 105 is connected with the first track 202, the second driving mechanism 106 is connected with the second track 203, and the first track 202 and the second track 203 are arranged in parallel without overlapping. The first driving mechanism 105 and the second driving mechanism 106 are controlled to move at different speeds, so that the first driving mechanism 105 and the second driving mechanism 106 are close to or away from each other, thereby causing the first trolley 101 and the second trolley 102 to rotate relative to the first driving mechanism 105 and the second driving mechanism 106, and cooperate with the trolley telescopic rod 104 to control the first trolley 101 and the second trolley 102 to twist at different angles during the movement of the trolley track 2, so as to simulate the posture changes during the driving process of the car, and then simulate the force conditions of the zero-gravity seat 7 and the passengers more realistically and comprehensively. At the same time, the trolley mechanism 1 is controlled to move on the trolley track 2, so that the control and monitoring of the movement state of the trolley mechanism 1 are more accurate and reliable. In summary, the device adjusts the angle of the trolley mechanism 1 to change the posture during the movement of the trolley track 2 by setting the first driving mechanism 105 to cooperate with the second driving mechanism 106, thereby simulating the force conditions of the zero-gravity seat 7 and the passengers more realistically and comprehensively.

[0036] Specifically, the first driving mechanism 105 includes a connecting shaft 111, a connecting plate 112, a driving motor 113 and a driving wheel 114, the driving motor 113 is arranged below the connecting plate 112, the driving wheels 114 are arranged on both sides of the driving motor 113, the connecting plate 112 is rotatably connected to the trolley mechanism 1 through the connecting shaft 111, the first track 202 is symmetrically arranged below both sides of the connecting plate 112, the driving wheel 114 is in contact with the first track 202, the first driving mechanism 105 is configured to have the same structure and size as the second driving mechanism 106, the first track 202 and the second track 203 are configured to have the same structure and size, and the connection method between the second driving mechanism 106 and the second track 203 is the same as the connection method between the first driving mechanism 105 and the first track 202. The device is provided with the connecting shaft 111 connected to the first trolley 101 and the second trolley 102 respectively, and the first trolley 101 and the second trolley 102 can rotate smoothly relative to the first driving mechanism 105 and the second driving mechanism 106 respectively. The driving motor 113 drives the driving wheels 114 on both sides to move along the trolley track 2, so that the movement of the trolley mechanism 1 is more stable.

[0037] Specifically, a T-shaped structure 204 is provided in the first track 202 and the second track 203, and track-holding structures 205 are symmetrically provided on both sides of the driving wheel 114, and the track-holding structure 205 includes an auxiliary rod 207 and an auxiliary wheel 208, and the auxiliary rod 207 is fitted with the T-shaped structure 204 through the auxiliary wheel 208. The T-shaped structure 204 cooperates with the auxiliary rod 207 and the auxiliary wheel 208 to force the driving wheel 114 to fit closely with the T-shaped structure 204, prevent the driving wheel 114 from being separated from the T-shaped structure 204, and ensure the driving effect of the driving wheel 114.

[0038] Specifically, the outer side of the driving wheel 114 is provided with an annular groove 115, and the top of the T-shaped structure 204 is provided with a protruding structure 206 that matches the annular groove 115. The protruding structure 206 matches the annular groove 115 to further ensure the fit between the driving wheel 114 and the T-shaped structure 204, and prevent the auxiliary wheel 208 or the driving wheel 114 from deviating from the T-shaped structure 204.

[0039] Example 2

[0040] See attached Figure 4-7The difference between this embodiment and embodiment 1 is that a detachable mounting plate 116 is installed on one side of the first trolley 101, a support wheel 117 is provided on the side of the mounting plate 116 away from the first trolley 101, a seat mounting seat 103 is provided on the side of the mounting plate 116 close to the first trolley 101, a first flip motor 3 and a second flip motor 4 are provided at both ends of the track base 201, a deflection assembly 5 is provided in the middle of the track base 201, and the front track base 201 is hinged to the rear track base 201 through the deflection assembly 5. Figure 4-6 When the zero-gravity seat 7 is tested for vehicle turning conditions, the first flip motor 3 and the second flip motor 4 drive the track base 201 to rotate 90 degrees, so that the track base 201 is perpendicular to the ground, and the deflection assembly 5 drives the track base 201 to deflect the required turning angle with the deflection assembly 5 as the center, so that the first drive mechanism 105 and the second drive mechanism 106 drive the mounting plate 116 to perform turning motion through the trolley mechanism 1, thereby driving the zero-gravity seat 7 installed on the mounting plate 116 to perform turning motion. When a turning test in the opposite direction is required, the zero-gravity seat 7 can be installed by rotating the orientation of 180 degrees, and the first drive mechanism 105 and the second drive mechanism 106 can be adjusted to perform opposite direction motion. By rotating the track base 201 90 degrees, the device can convert the turning motion during the turning condition test into a motion similar to an uphill slope for the first drive mechanism 105 and the second drive mechanism 106, so that the zero-gravity seat 7 moving along the trolley track 2 can adjust the turning angle more smoothly and conveniently.

[0041] Specifically, a telescopic cylinder 401 is connected to the side of the second flip motor 4 away from the track base 201, and the side of the telescopic cylinder 401 away from the second flip motor 4 is hinged to an electric slider 402, and a sliding track 403 is provided on one side of the electric slider 402, and the electric slider 402 is slidably connected to the sliding track 403. By setting the telescopic cylinder 401 to telescope and cooperate with the movement of the electric slider 402, the device can assist the deflection assembly 5 and the track base 201 to rotate, so that the angle adjustment of the track base 201 is more reliable.

[0042] Specifically, the deflection assembly 5 includes a deflection motor 501 and a connecting shaft 502. The deflection motor 501 is arranged on a side of the track base 201 close to the trolley track 2. The upper part of the T-shaped structure 204 is provided with a connecting shaft 502. The front T-shaped structure 204 is hinged with the rear T-shaped structure 204 through the connecting shaft 502. The motor shaft of the deflection motor 501 and the connecting shaft 502 rotate around the same axis. The deflection motor 501 drives the track base 201 to rotate around the motor shaft of the deflection motor 501 to adjust the deflection angle of the track base 201. Refer to the attached Figure 7 The motor shaft and the connecting shaft 502 are configured to rotate around the same axis, so that after the T-shaped structure 204 rotates with the track base 201 , the driving wheel 114 and the auxiliary wheel 208 can still move along the T-shaped structure 204 .

[0043] Specifically, a plurality of deflection assemblies 5 are provided in the middle of the track base 201. In this embodiment, four deflection assemblies 5 are provided, and the plurality of deflection assemblies 5 make the rotation angle of the track base 201 change more gradually, so that the movement of the trolley mechanism 1 along the trolley track 2 is smoother.

[0044] Specifically, the auxiliary rod 207 is configured as a spring telescopic rod 209. The spring telescopic rod 209 can ensure that the driving wheel 114 and the auxiliary wheel 208 have pressure in the direction of the T-shaped structure 204, ensuring that they fit with the T-shaped structure 204, and prevent the auxiliary wheel 208, the driving wheel 114, and the T-shaped structure 204 from fitting too closely when the first driving mechanism 105 and the second driving mechanism 106 pass through the connecting shaft 502, causing the device to break and be damaged.

[0045] Specifically, a telescopic support rod 6 is provided on one side of the track base 201 away from the trolley track 2, and the telescopic support rod 6 is hinged to the track base 201. The telescopic support rod 6 is detachably connected to the ground, and the telescopic support rod 6 can support the track base 201 by adjusting the connection position with the ground and its own slope, thereby improving the reliability of the device.

Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. The protection scope of the present invention should be based on the protection scope of the claims.
