[0008] In the aforementioned simulated load table hinge torque stepless adjustment loading device, the main shaft swings from -30° to +30°; through the limiting of the main shaft and the shift fork, the top of the spring steel plate assembly bends; and in the clamping state of the spring steel plate clamping device, the top of the spring steel plate assembly is restored by the self-resetting force of the spring steel plate assembly, thereby providing hinge torque loading.

[0010] In the aforementioned simulated load table hinge torque stepless adjustment loading device, n is a positive integer not less than 3.

[0011] In the aforementioned simulated load table hinge torque stepless adjustment loading device, the number of through holes at the bottom of the fork groove corresponds to the number of spring steel plates n, so that n sets of spring steel plates are vertically exposed from the through holes at the bottom of the fork groove and clamped by the spring steel plate clamping device.

[0012] In the aforementioned simulated load table hinge torque stepless adjustment loading device, the main spindle fork, spring steel plate clamping device, support plate, and fork shaft are all made of 95Cr18 stainless steel; the wear-resistant copper sleeve is made of high-strength brass.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] This invention provides a simulated load table hinge torque stepless adjustment loading device. The simulated load hinge torque loading structure mainly consists of a spindle fork and spring steel plates of various specifications, sizes and materials. During operation, the spindle rotates and the fork moves the spring steel plates to complete the hinge torque loading function, which can realize miniaturization, universality and stepless adjustment of hinge torque.

[0024] A loading device with continuously adjustable hinge torque, simulating a load table. Figure 1 As shown, the assembly specifically includes a spindle fork 1, a spring steel plate assembly 2, a spring steel plate clamping device 3, and two support plates 4. The spindle fork 1 includes a spindle 101 and a fork 102. The two support plates 4 are placed vertically relative to each other. The spindle 101 is horizontally positioned at the top between the two support plates 4, with both ends of the spindle 101 passing through the two support plates 4 respectively. The fork 102 is fixedly installed at the bottom of the spindle 101. The top of the spring steel plate assembly 2 is limited between the fork 102 and the spindle 101. The bottom of the fork 102 has uniformly spaced through holes. The bottom end of the spring steel plate assembly 2 extends vertically downward from the through holes of the fork 102. The spring steel plate clamping device 3 is horizontally positioned at the middle between the two support plates 4, with both ends of the spring steel plate clamping device 3 passing through the two support plates 4 respectively. The spring steel plate clamping device 3 clamps the front and rear sides of the spring steel plate assembly 2.

[0025] The shift fork 102 has an upward-opening U-shaped groove structure; the top of the spring steel plate assembly 2 is embedded in the groove of the shift fork 102; and a through hole corresponding to the spring steel plate assembly 2 is opened at the bottom of the groove of the shift fork 102.

[0026] The side wall of the support plate 4 is provided with an adjustment groove in the vertical direction; the two ends of the spring steel plate clamping device 3 can be moved along the adjustment groove to adjust the height of the spring steel plate clamping device 3, that is, to adjust the clamping position of the spring steel plate clamping device 3 on the spring steel plate assembly 2.

[0027] Specifically, the height adjustment range of the spring steel plate clamping device 3 is from 202695mm to 202160mm from the shift fork shaft; the torque loading range corresponding to different heights of the spring steel plate clamping device 3 is 1-769.5Nm.

[0028] The main shaft 101 can swing from -30° to +30°; through the limiting of the main shaft 101 and the shift fork 102, the top of the spring steel plate assembly 2 is driven to bend; and in the clamping state of the spring steel plate clamping device 3, the top of the spring steel plate assembly 2 is restored by its own restoring force, thereby providing hinge torque loading.

[0029] like Figure 2 As shown, the spring steel plate assembly 2 includes n-1 anti-friction copper sleeves 201, a shift fork shaft 202, and 3n spring steel plates 203; wherein, the shift fork shaft 202 is a horizontally placed rod-shaped structure; the 3n spring steel plates 203 are divided into n groups of 3 spring steel plates 203; the n groups of spring steel plates 203 are evenly spaced and fitted onto the shift fork shaft 202, and all spring steel plates 203 are placed vertically; adjacent groups of spring steel plates 203 are separated by one anti-friction copper sleeve 201; the anti-friction copper sleeve 201 is fitted onto the shift fork shaft 202. n is a positive integer not less than 3.

[0030] The number of through holes at the bottom of the groove of the shift fork 102 corresponds to the number of spring steel plates 203, n, so that n sets of spring steel plates 203 are vertically exposed from the through holes at the bottom of the groove of the shift fork 102 and clamped by the spring steel plate clamping device 3.

[0031] The spindle fork 1, spring steel plate clamping device 3, support plate 4, and fork shaft 202 are all made of 95Cr18 stainless steel; the anti-friction copper sleeve 201 is made of high-strength brass. The spring steel plate 203 is made of 60Si2MnA high-quality spring steel; the yield strength is 1100MPa, and the tensile strength is 1200MPa; a single spring steel plate 203 provides a torque gradient of 1-2.85Nm / °.

[0032] In this invention, the spindle fork 1 is supported by two support plates 4. When the spindle fork 1 rotates, it actuates the spring steel plate assembly 2 to apply hinge torque. The hinge torque of the spring steel plate assembly 2 can be adjusted in three dimensions: increasing or decreasing the number of clamping plates, changing the size of the spring steel plates, and changing the material of the spring steel plates. The spring steel plate clamping device 3 can adjust the clamping distance of the spring steel plate assembly 2 vertically through the pre-reserved slots on the support plates 4, thereby theoretically achieving "stepless adjustment" of the hinge torque in four dimensions.

[0033] The design is that the spring steel plate assembly 2 is mainly composed of a friction-reducing copper sleeve 201, a shift fork shaft 202, and a spring steel plate 203. The shift fork shaft 202 passes through the friction-reducing copper sleeve 201 and the spring steel plate 203 to achieve torque loading of the spring steel plate assembly. The friction-reducing copper sleeve 201 is relatively soft and its main function is to reduce friction with the main shaft shift fork 1, protect the shift fork structure, and reduce working noise. The friction-reducing copper sleeve 201 is replaced as needed according to the usage.

[0034] The hinge torque loading of this invention adopts a fork structure, which has the ability to load large torque and miniaturize the design. Furthermore, the spring steel plate that provides hinge torque loading can achieve stepless adjustment of hinge torque by changing four dimensions: clamping quantity, size, material, and clamping distance, making it suitable for a wide range of applications.

[0035] In this invention, the hinge torque adopts a longitudinal multi-piece layout, which releases lateral space and reduces the footprint.

[0036] The simulated load stage adopts a redundant design, and the multi-spring steel plate design improves the fault tolerance. Even if one of the steel plates breaks, the torque can be adjusted by changing the clamping distance to ensure that the test can be carried out continuously without interruption.

Any person skilled in the art can make possible changes and modifications to the technical solutions of the present invention by utilizing the methods and techniques disclosed above without departing from the spirit and scope of the present invention.
