DETAILED DESCRIPTION

[0037] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1

[0039] like Figure 1 The vehicle seat frame detection device shown includes a transverse movement mechanism 1, a clamping mechanism 2 and a ballast mechanism 3. The seat frame is installed on the transverse movement mechanism 1, and the transverse movement mechanism 1 can drive the seat frame to move horizontally left and right. The clamping mechanism 2 is distributed on both sides of the transverse movement mechanism 1, and is used to clamp and fix the seat pan of the seat frame so that the slide rail of the seat frame can slide relatively with the transverse movement mechanism 1. The ballast mechanism 3 is installed above the transverse movement mechanism, and is used to apply pressure to the seat frame.

[0040] like Figure 2 As shown, the transverse mechanism 1 includes a transverse guide rail 11, a transverse platform 12 and a transverse driving member 13. The two transverse guide rails 11 are installed in parallel, the transverse platform 12 is movably installed on the two transverse guide rails 11 through a slider, and the transverse driving member 13 is a lead screw linear module, which is installed between the two transverse guide rails 11. A first force sensor 14 is installed on the nut seat of the lead screw linear module, and the other end of the first force sensor 14 is connected to the transverse platform 12. The lead screw linear module drives the transverse platform 12 to reciprocate along the transverse guide rail 11 through the first force sensor 14, and can realize precise control of the position of the transverse platform 12. When the lead screw linear module drives the transverse platform 12 to move left, the first force sensor 14 measures the pressure of the transverse driving member 13 on the transverse platform 12; when the lead screw linear module drives the transverse platform 12 to move right, the first force sensor 14 measures the pulling force of the transverse driving member 13 on the transverse platform 12.

[0041] like Figure 2 As shown, two clamping parts 4 are installed on the left side of the upper end surface of the transverse moving platform 12, and two locking parts 5 are installed on the right side of the upper end surface of the transverse moving platform 12. The front end of the slide rail of the seat frame is clamped with the clamping part 4, and the rear end of the slide rail of the seat frame is connected with the locking part 5. The clamping part 4 and the locking part 5 can enable the seat frame to be quickly installed on the transverse moving platform 12, or quickly removed from the transverse moving platform 12, so as to improve the detection efficiency of the seat frame.

[0042] like Figure 3 As shown, the clamping member 4 includes a clamping base 41 and a clamping block 42, and the clamping base 41 is fixed to the transverse platform 12 by bolts. A clamping groove 411 is provided on the left side of the upper end surface of the clamping base 41, and a clamping positioning pin 43 is vertically installed at the bottom of the clamping groove 411. The clamping block 42 is fixed to the left side of the clamping base 41 by bolts, and the upper end of the clamping block 42 extends upward to the upper side of the clamping groove 411, thereby forming a clamping position on the left side of the clamping groove 411. During installation, the front side of the slide rail of the seat frame is clamped in the clamping position, and the fixing hole connecting the front end of the slide rail to the car floor is inserted on the clamping positioning pin 43.

[0043] like Figure 4As shown, the locking member 5 includes a locking base 51, the upper end surface of the locking base 51 is provided with a locking groove 511, and a locking positioning pin 53 is vertically installed at the bottom of the locking groove 511. The two sides of the locking groove 511 are of different heights. A locking block 52 is installed on the side of the locking base 51, and the locking block 52 is located on the lower side of the locking groove 511, and the two locking blocks 52 are located on the side adjacent to the two locking members 5. The lower end of the locking block 52 is hinged to the lower end of the locking base 51, and a protrusion is fixed on the upper end of the locking block 52, and the protrusion faces the side of the locking groove 511. A locking driving member 54 is fixed to the lower end surface of the transverse platform 12, and the locking driving member 54 abuts against the side of the locking block 52. A reset spring 55 is installed on the side of the locking base 51, and the reset spring 55 pushes the locking block 52 away from the locking base.

[0044] During installation, the rear side of the slide rail of the seat frame is installed in the locking groove 511, and the fixing hole connecting the rear end of the slide rail to the car floor is inserted into the locking positioning pin 53. When the locking drive 54 moves up, the locking drive 54 pushes the locking block 52 close to the locking base 51, and the protrusion presses the seat frame on the locking base 51 to achieve the locking of the locking member 5; when the locking drive 54 moves down, the return spring 55 pushes the locking block 52 away from the locking base 51, so that the protrusion is staggered with the locking base 51, and the locking member 5 is unlocked. The two sets of clamping parts 4 and the two sets of locking members 5 jointly realize the rapid locking or unlocking of the seat frame.

[0045] like Figure 1 , Figure 5 As shown, the clamping mechanism 2 includes a clamping drive 21 and a clamping block 22. The two clamping drives 21 are installed on both sides of the transverse mechanism 1 through a clamping bracket 23, and the two clamping drives 21 are arranged opposite to each other. The clamping block 22 is installed at the driving end of the clamping drive 21, and the clamping drive 21 can drive the clamping block 22 to move closer to or away from the seat frame. The clamping drive 21 is a cylinder. When the cylinder is extended, the clamping block 22 abuts against both sides of the seat pan of the seat frame to fix the position of the seat frame; when the cylinder is retracted, the clamping block 22 is separated from the seat frame.

[0046] The clamping block 22 can be a cylindrical structure or a clamp that conforms to the outer shape of the seat frame. A rubber pad is attached between the clamping block 22 and the seat frame. On the one hand, the friction between the clamping block 22 and the seat frame can be increased to prevent the clamping block 22 and the seat frame from sliding relative to each other. On the other hand, the clamping block 22 can prevent the seat frame from being crushed or scratched. In order to further improve the clamping effect of the clamping mechanism 2, the clamping drive members 21 can be four or six, and the clamping drive members 21 are symmetrically distributed on both sides of the transverse mechanism 1.

[0047] like Figure 6-Figure 8As shown, the ballast mechanism 3 includes a gantry 31, which is installed at the right end of the transverse movement mechanism 1. Two vertical guide rails 32 are symmetrically installed on the left end surface of the gantry 31, and a crossbeam 33 is installed between the two vertical guide rails 32 through a slider. Two vertical driving members 34 are installed on the top of the gantry 31. The vertical driving members 34 are cylinders, which are parallel to the vertical guide rails 32. The lower end of the cylinder is connected to the crossbeam 33, and the cylinder drives the crossbeam 33 to move up and down along the vertical guide rails 32.

[0048] like Figure 6-Figure 8 As shown, a connecting plate 331 is welded and fixed to the lower end of the middle part of the cross beam 33, and the lower end surface of the connecting plate 331 is connected to the ballast platform 34 through the second force sensor 35. Four linear guide columns 36 are installed between the connecting plate 331 and the ballast platform 34, and the linear guide columns 36 are used to limit the inclination of the ballast platform 34 to ensure the accuracy of the detection of the second force sensor 35.

[0049] like Figure 6-Figure 8 As shown, two horizontal guide rails are installed at the lower end of the ballast platform 34, and the horizontal guide rails are arranged in parallel with the crossbeam 33. An adjustment platform 37 is movably installed on the horizontal guide rails through a slider, and a ballast member 38 is installed at the lower end of the adjustment platform 37. An adjustment drive member is installed between the adjustment platform 37 and the ballast platform 34, and the adjustment drive member can control the adjustment platform 37 to move along the horizontal guide rails, thereby changing the position of the ballast member 38. Since the center of gravity of the driver's seat frame and the passenger seat frame is different, the position of the ballast member 38 can be changed by moving the adjustment platform 37, which can adapt to the detection of different seat frames.

[0050] like Figure 7 , Figure 8 As shown, the right side of the upper end surface of the ballast member 38 is hinged to the lower end surface of the ballast platform 37 through the rotating shaft 381, and the left side of the upper end surface of the ballast member 38 is connected to the left side surface of the ballast platform 37 through the flip driving member 39. The flip driving member 39 is a double-hinged cylinder, and the two ends of the double-hinged cylinder are respectively hinged to the ballast member 38 and the ballast platform 37. When the double-hinged cylinder is extended, the ballast member 38 flips counterclockwise; when the double-hinged cylinder is contracted, the ballast member 38 flips clockwise. The flip driving member 39 can drive the ballast member 38 to flip a certain angle, so that the ballast member 38 fits more closely with the seat frame, thereby ensuring the accuracy of the detection.

[0051] like Figure 7 , Figure 8As shown, the left end of the upper end surface of the ballast member 38 is provided with two slots 382, ​​and the side of the ballast member 38 is provided with a threaded hole 383 connected to the side wall of the slot 382. The lower end of the auxiliary ballast member 34 is fixed with two plugs that match the slots 382. The auxiliary ballast member 384 is plugged into the slots through the plugs, so that the auxiliary ballast member 384 is vertically connected to the ballast member 38. The threaded hole 383 is threaded with a locking bolt, and the locking bolt abuts against the plug to achieve the locking of the auxiliary ballast member 384 and the ballast member 38. The auxiliary ballast member 384 is used for static load detection of the seat frame backrest.

[0052] Example 2

[0053] A detection method of a vehicle seat frame detection device according to embodiment 1,

[0054] When testing the seat pan static load:

[0055] The seat frame is installed on the transverse platform 12, and the left-moving frame is moved to the bottom of the ballast mechanism 3 through the transverse driving member 13, and the ballast member 38 is driven down to the seat basin through the vertical driving member 34. The pressure of the ballast member 38 is adjusted through the second force sensor 35 to realize the detection of the static load of the seat basin.

[0056] Before the seat pan static load test, the position of the ballast member 38 can be adjusted by adjusting the platform 37 so that the ballast member 38 is loaded at the normal sitting position of the seat pan to improve the test accuracy. During the seat pan static load test, the ballast member 38 can be driven by the flip driving member 39 to change the angle to simulate the posture change of the driver and passenger when sitting, so as to make the test result more accurate.

[0057] When testing the static load of the backrest:

[0058] The seat frame is installed on the transverse platform 12, and the ballast member 38 is driven downward by the vertical drive member 34 so that the auxiliary ballast member 384 contacts the rear side of the seat frame backrest. The seat frame is moved by the transverse drive member 13 so that the seat frame backrest and the auxiliary ballast member 384 are squeezed so that the auxiliary ballast member 384 pushes the seat frame backrest from back to front. The pressure between the auxiliary ballast member 384 and the seat frame backrest is adjusted by the first force sensor 14 and the second force sensor 35 to detect the static load on the rear side of the seat frame backrest.

[0059] The seat frame is installed on the transverse platform 12, and the ballast member 38 is driven downward by the vertical drive member 34, and is driven to flip 90° by the flip drive member 39, so that the ballast member 38 is in a vertical state and contacts the front side of the seat frame backrest, and the seat frame is moved by the transverse drive member 13 so that the seat frame and the ballast member 38 are squeezed, so that the ballast member 38 pushes the seat frame backrest from front to back, thereby realizing the detection of the static load on the front side of the seat frame backrest.

[0060] When the seat frame backrest is subjected to static load testing, the ballast member 38 can be driven by the flipping driving member 39 to achieve angle change, so as to change the contact angle between the auxiliary ballast member 384 or the ballast member 38 and the seat frame backrest, so as to simulate the posture changes of the driver and passengers when riding, so as to make the test results more accurate.

[0061] When testing the slide rail force:

[0062] The seat frame is installed on the transverse platform 12, and is moved to the bottom of the ballast mechanism 3 through the transverse driving member 13. The ballast member 38 is driven downward through the vertical driving member 34, and the downward pressure of the ballast member 38 is adjusted through the second force sensor 35. The clamping mechanism 2 is driven to clamp the seat pan of the seat frame from both sides to ensure that the seat pan of the seat frame is stationary. The transverse driving member 13 drives the transverse platform 12 to move back and forth, driving the slide rail of the seat frame to slide back and forth relative to each other, and the first force sensor 14 is used to detect the slide rail force of the seat frame.

[0063] When testing the slide rail force of the seat frame, the ballast member 38 can be driven by the flipping driving member 39 to achieve angle changes, so as to simulate the posture changes of the driver and passengers when sitting, so as to make the test results more accurate.

[0064] In addition, since the slide rails of the seat frame are driven to slide relative to each other by the transverse platform 12, the step of installing a fixture to clamp the seat frame for sliding can be omitted, which is beneficial to improving the detection efficiency.

[0065] The technical solution provided in the embodiments of the present application has at least the following technical effects or advantages:

[0066] 1. Through the cooperation of the lateral movement mechanism, the clamping mechanism and the reversible ballast mechanism, the static load detection of the seat frame, the static load detection of the backrest and the slide rail force detection can be realized. On the one hand, the detection range of the detection device is expanded and the detection cost is reduced; on the other hand, the disassembly and assembly time of the seat frame on different detection devices is reduced, and the detection efficiency is improved;

[0067] 2. By adjusting the platform and the flippable ballast part, the contact position and contact angle between the ballast mechanism and the seat frame can be adjusted, making the detection more suitable for actual use and improving the detection accuracy of the detection device;

[0068] 3. The seat frame is clamped by the clamping mechanism, and the slide rail is driven to move relative to the seat frame by the lateral platform, which eliminates the disassembly and assembly process required for the existing slide rail force detection to be directly connected to the seat frame, reduces the detection difficulty, and improves the detection efficiency;

[0069] 4. The position of the ballast can be adjusted by adjusting the platform to suit the detection of seat frames in different positions, thereby improving the convenience and versatility of the detection device.
