[0019] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0020] The following is for reference. Figures 1-3 Describes a force measurement system 100 for a vehicle power suspension according to an embodiment of the present invention.

[0021] Combination Figure 1 and Figure 2As shown, the force measurement system 100 for a vehicle power suspension according to an embodiment of the present invention mainly includes: a housing 10, a drive component 20, and a transmission assembly 30. The housing 10 contains a power suspension fixing part 11 for fixing the vehicle power suspension, ensuring the structural stability of the vehicle power suspension during the force measurement process, which helps improve the accuracy of the force measurement results.

[0022] Furthermore, the power output end of the drive member 20 extends into the housing 10 and is provided with a drive gear 21. The transmission assembly 30 includes a lead screw member 31 and a pressing member 32. The lead screw member 31 is rotatably disposed in the housing 10 and is provided with a transmission gear 311 on its top. The transmission gear 311 meshes with the drive gear 21 for transmission.

[0023] Specifically, the drive component 20 can generate the power required for the force measurement system 100 of the vehicle power suspension to operate. In an embodiment of this utility model, the power output end of the drive component 20 extends into the housing 10 to transmit the output power of the drive component 20 to the drive gear 21 inside the housing 10, so that the drive component 20 can drive the drive gear 21 inside the housing 10 to rotate.

[0024] In the embodiments of this utility model, the driving component 20 includes, but is not limited to, a rotating motor. A flange 22 is installed on the outer sleeve of the rotating motor. Fixing bolts 23 are evenly embedded on the surface of the flange 22. The rotating motor can be fixed on the housing 10 by the fixing bolts 23 and the flange 22, so that the driving component 20 can ensure good stability during operation.

[0025] Furthermore, a transmission connecting rod 24 is installed at the output end of the drive component 20. The transmission connecting rod 24 is connected to the drive gear 21 so that the output power of the drive component 20 can be transmitted to the drive gear 21.

[0026] Furthermore, the transmission assembly 30 inside the housing 10 includes a lead screw 31 and a pressing member 32. A transmission gear 311 is provided on the top of the lead screw 31. The transmission gear 311 is used to mesh with the drive gear 21 for transmission, so that the drive gear 21 can drive the transmission gear 311 to rotate, which in turn can drive the lead screw 31 to rotate.

[0027] Furthermore, the pressing member 32 has a nut 321, which is sleeved on the lead screw member 31 and engages with the lead screw member 31 for transmission. Thus, when the lead screw member 31 rotates, the nut 321 engages with the lead screw member 31. By adjusting the rotation direction of the lead screw member 31, the nut 321 can move in the up and down direction, thereby allowing the pressing member 32 to move up and down.

[0028] In this way, the lead screw 31 can drive the pressing member 32 to move closer to or away from the power suspension fixing part 11 through the nut 321, so as to selectively press and test the power suspension.

[0029] Therefore, this utility model embodiment provides a lead screw 31 and a pressing member 32 inside the housing 10. The lead screw 31 and the driving member 20 are connected by gear transmission. The pressing member 32 is driven by the lead screw 31 through a nut 321. When the driving member 20 outputs power, it can drive the pressing member 32 to selectively press the test power suspension. The structure is simple and the transmission efficiency is high, which makes it easy to measure the force of the power suspension and improves the detection efficiency.

[0030] Combination Figure 1 and Figure 2 As shown, there are multiple lead screw components 31, and the transmission gears 311 on the top of the multiple lead screw components 31 mesh with the drive gear 21 for transmission. Multiple nuts 321 are provided on the pressing component 32, and the multiple nuts 321 mesh with the multiple lead screw components 31 one by one for transmission.

[0031] Specifically, the pressing member 32 is equipped with multiple nuts 321 that mesh with multiple lead screws 31 in a one-to-one correspondence. The drive gear 21 can drive the multiple lead screws 31 to rotate simultaneously. This allows the multiple nuts 321 on the pressing member 32 to move simultaneously in the up and down direction, so that the lead screws 31 can drive the pressing member 32 to move closer to or away from the power mount fixing part 11 through the multiple nuts 321. This can ensure the smooth operation of the pressing member 32 when pressing and testing the power mount, and ensure the uniformity of the pressing force applied by the pressing member 32 to the power mount. This is beneficial to improving the accuracy of the force measurement results of the vehicle's power mount.

[0032] Combination Figure 1 and Figure 2 As shown, the pressing member 32 includes a pressure testing rod 322. A connecting block 323 is provided on the top of the pressure testing rod 322. The connecting block 323 is connected to the nut 321 through a connecting rod 324. This allows multiple nuts 321 to be connected to the pressure testing rod 322, so that multiple nuts 321 can jointly drive the pressure testing rod 322 to move in the vertical direction, so that the pressing member 32 can move closer to or away from the power suspension fixing part 11, thereby selectively pressing and testing the power suspension.

[0033] Furthermore, a pressing plate 325 is provided at the bottom of the pressure testing rod 322, which corresponds to the upper part of the power mount fixing part 11. In this way, when the pressure testing rod 322 approaches or moves away from the power mount fixing part 11, the pressing plate 325 can also approach or move away from the power mount fixing part 11 along with the pressure testing rod 322. When the pressing plate 325 approaches the power mount fixing part 11, it can press the vehicle's power mount. When the pressing plate 325 moves away from the power mount fixing part 11, it does not press the vehicle's power mount. This allows the pressing element 32 to selectively press and test the power mount.

[0034] Furthermore, a pressure sensor 326 is provided on the pressure measuring rod 322. The pressure sensor 326 is electrically connected to the pressing plate 325. When the pressing plate 325 approaches the power mount fixing part 11, the pressing plate 325 presses the power mount of the vehicle. At this time, the pressing force generated by the pressing plate 325 on the power mount of the vehicle is equal to the reaction force generated by the power mount of the vehicle on the pressing plate 325. The pressing plate 325 can convert the received reaction force of the power mount on the pressing plate 325 into an electrical signal and transmit it to the pressure sensor 326. After receiving this signal, the pressure sensor 326 can obtain the force measurement result of the power mount.

[0035] Combination Figure 2 As shown, the force measurement system 100 of the vehicle power suspension also includes a control panel 40, which is electrically connected to the drive unit 20 and the pressure sensor 326.

[0036] Specifically, the control panel 40 is electrically connected to the drive component 20, allowing the transmission of electrical signals between them. The control panel 40 can send electrical signals to the drive component 20 to control its rotation direction, which in turn controls the rotation direction of the drive gear 21 inside the housing 10. Controlling the rotation direction of the drive gear 21, in turn, controls the rotation direction of the lead screw 31. In this embodiment, a contactor 12 is installed at the top of the inner wall of the housing 10. The contactor 12 is electrically connected to the control panel 40. The control panel 40 transmits electrical signals to the contactor 12 to control the drive component 20 to rotate forward or backward. It should be noted that forward rotation can be either clockwise or counterclockwise, while counterclockwise rotation is the opposite of forward rotation.

[0037] Furthermore, the control panel 40 is electrically connected to the pressure sensor 326, which allows electrical signals to be transmitted between the control panel 40 and the pressure sensor 326. The force measurement results of the vehicle power suspension detected by the pressure sensor 326 can be transmitted to the control panel 40 to collect the force measurement values ​​of the vehicle power suspension.

[0038] In this embodiment of the invention, the power input terminals of the drive unit 20, contactor 12, pressure sensor 326, and control panel 40 are all electrically connected to the power output terminal of the indoor power supply, which provides power support to the force measurement system 100 of the vehicle power suspension. The signal input terminals of the drive unit 20, contactor 12, and pressure sensor 326 are all signal connected to the signal output terminal of the control panel 40, which sends signals to the drive unit 20, contactor 12, and pressure sensor 326 to control the operation of the force measurement system 100 of the vehicle power suspension, and simultaneously records the impact force value detected by the pressure sensor 326.

[0039] Combination Figure 1 and Figure 2As shown, the force measurement system 100 of the vehicle power suspension also includes a support plate 50, which is disposed inside the housing 10, and the bottom of the lead screw 31 is rotatably disposed on the support plate 50.

[0040] Specifically, the bottom of the lead screw 31 is connected to the support plate 50, so that the support plate 50 can provide support for the bottom of the lead screw 31 to ensure the structural stability of the lead screw 31 during transmission. In addition, a rotating shaft 52 is provided inside the support plate 50, and the bottom of the lead screw 31 cooperates with the rotating shaft 52. This allows the lead screw 31 to be rotatably mounted on the support plate 50 so that the lead screw 31 can rotate normally in the housing 10. This allows the nut 321 to mesh with the lead screw 31 for transmission, thereby driving the pressing member 32 to move up and down.

[0041] Furthermore, a guide hole is provided on the support plate 50, through which the pressure testing rod 322 passes at least partially, and is guided and engaged with the side wall of the guide hole in the vertical direction. Specifically, in the embodiment of this utility model, both the power suspension fixing part 11 and the support plate 50 are located inside the housing 10, and the power suspension fixing part 11 is located on the lower side of the support plate 50. Both the left and right ends of the support plate 50 are connected to the side wall of the housing 10. The guide hole on the support plate 50 allows the pressure testing rod 322 to pass through the guide hole, so that the pressing plate 325 can extend into the lower part of the support plate 50. This allows the pressing plate 325 to selectively press and test the power suspension when the pressure testing rod 322 approaches or moves away from the power suspension fixing part 11.

[0042] In an embodiment of this utility model, a guide plate 511 is provided inside the guide hole, and a guide wheel 512 is provided on the side wall of the guide plate 511. When the pressure measuring rod 322 extends into the guide hole, the guide wheel 512 rolls with the side wall of the pressure measuring rod 322 to reduce the friction force when the pressure measuring rod 322 moves up and down. This allows the pressure sensor 326 to more accurately measure the impact force value of the power suspension on the pressing plate 325 when the pressing plate 325 approaches the power suspension fixing part 11 to press the power suspension, thereby facilitating the obtaining of more accurate force measurement results of the vehicle power suspension.

[0043] Combination Figures 1-3As shown, the force measurement system 100 for the vehicle power mount also includes a power mount fixing assembly 60. The power mount fixing assembly 60 includes an upper fixing rod 61 and a lower fixing rod 62. The upper fixing rod 61 is positioned above the lower fixing rod 62 and has an upper limit groove 611 at its bottom. The lower fixing rod 62 has a lower limit groove 621 at its top. The upper limit groove 611 and the lower limit groove 621 are arranged opposite each other in the vertical direction and form a power mount fixing groove. The power mount fixing groove is suitable for cooperating with the vehicle power mount so that the vehicle power mount is fixed in the force measurement system 100. This facilitates the force measurement system 100 to measure the force of the vehicle power mount and avoids damage caused by the power mount not being securely fixed during the testing process.

[0044] Furthermore, the power mount fixing slot is divided into an upper fixing slot and a lower fixing slot, with the upper fixing slot located on the upper fixing rod 61 and the lower fixing slot located on the lower fixing rod 62. This not only ensures the structural reliability of the upper and lower fixing slots, but also facilitates the installation of the vehicle's power mount in the power mount fixing assembly 60, thus enabling the installation and removal of the vehicle's power mount.

[0045] Combination Figure 1 As shown, the power mount fixing assembly 60 includes a first power mount fixing assembly 63 and a second power mount fixing assembly 64. The first power mount fixing assembly 63 and the second power mount fixing assembly 64 are located on both sides of the housing 10 in the left and right directions and are arranged opposite to each other. The power mount fixing grooves of the first power mount fixing assembly 63 and the second power mount fixing assembly 64 are respectively suitable for fixing the left and right ends of the power mount.

[0046] Specifically, during the process of the force measurement system 100 of the vehicle power mount measuring the force of the power mount, the pressing member 32 will apply a large pressing force to the power mount and generate a large impact force. Therefore, it is necessary to ensure the stability and reliability of the power mount setting on the force measurement system 100 of the vehicle power mount.

[0047] In an embodiment of this utility model, a first power suspension fixing component 63 and a second power suspension fixing component 64 are arranged opposite each other in the left and right directions of the force measurement system 100 of the vehicle power suspension. In this way, the first power suspension fixing component 63 and the second power suspension fixing component 64 can support the left and right ends of the vehicle power suspension respectively, so as to ensure the stability and reliability of the vehicle power suspension in the force measurement system 100 during the force measurement process, which helps to improve the accuracy of the force measurement results of the vehicle power suspension.

[0048] Combination Figure 1 and Figure 3As shown, the upper fixing rod 61 is provided with a plurality of positioning grooves 612 spaced apart in the vertical direction, and the side wall of the housing 10 in the left and right direction is provided with a positioning rod 65. The positioning rod 65 is selectively positioned and engaged with one of the plurality of positioning grooves 612 to adjust the size of the power suspension fixing groove according to different power suspensions.

[0049] Specifically, in this embodiment of the present invention, the positioning rod 65 is a positioning screw. The positioning screw can selectively extend into any one of the multiple positioning grooves 612 spaced apart in the vertical direction on the upper fixed rod 61, so that the upper positioning rod 65 is fixed in different positions in the vertical direction. In this way, through the selective cooperation between the positioning rod 65 and the positioning groove 612, the distance between the upper fixed rod 61 and the lower fixed rod 62 in the vertical direction can be adjusted. This allows the distance between the upper fixed groove and the lower fixed groove to be adjusted, thereby adjusting the size of the power mount fixing groove. This allows the size of the power mount fixing groove to be adjusted according to the size of the power mount, and thus the force measuring system 100 of the vehicle power mount in this embodiment of the present invention can be applied to power mounts of different sizes.

[0050] Combination Figure 1 and Figure 3 As shown, a control handle 613 is provided at the top of the upper fixing rod 61. Specifically, the control handle 613 is provided at the top of the upper fixing rod 61, which makes it easy to hold the control handle 613 to move the upper fixing rod 61 up and down, thereby adjusting the distance between the upper fixing rod 61 and the lower fixing rod 62 in the vertical direction. This improves the ease of adjusting the size of the power mount fixing groove, thereby improving the operational convenience of the force measurement system 100 of the vehicle's power mount.

[0051] Combination Figure 1 As shown, the force measurement system 100 of the vehicle power suspension also includes a support plate 70 and a support frame 80. The housing 10 is disposed on the upper side of the support plate 70, and the support frame 80 is disposed on the lower side of the support plate 70. Specifically, the support plate 70 is installed at the bottom of the housing 10, and multiple support frames 80 are installed at the bottom of the support plate 70. The multiple support frames 80 are arranged circumferentially along the bottom of the support plate, so that the multiple support frames 80 can provide uniform and reliable support to the support plate, thereby ensuring the stability of the housing 10 on the support plate.

[0052] Furthermore, this utility model places the housing 10 of the vehicle power suspension force measurement system 100 on the tray 70 and the support frame 80, so that the height of the housing 10 can reach the height used by the staff. This can improve the ease of operation of the vehicle power suspension force measurement system 100 and help improve the force measurement efficiency of the power suspension.

[0053] In this embodiment of the utility model, during use, the operator raises the upper fixing rod 61 by manipulating the handle 613, and then adjusts the positioning rod 65 to engage with one of the multiple positioning slots 612 on the upper fixing rod 61 to fix the power suspension. After the power suspension is fixed, the control panel 40 controls the drive component 20 and the contactor 125 to make the drive component 20 run forward. The operation of the drive component 20 drives the drive gear 21 to run, and at the same time drives the meshing transmission gear 311 to rotate, and also drives the lead screw component 31 to rotate. While the lead screw component 31 is rotating, the nut 321 sleeved on the lead screw component 31 can be moved downward under the action of the thread rotation. While the nut 321 is moving downward, the pressing plate 325 moves downward to press the power suspension. At the same time as pressing, the pressure sensor 326 transmits the detected impact force to the control panel 40 for storage, and calculates the impact resistance of the power suspension according to the corresponding formula.
