Description

Technical Field

[0001] This utility model relates to the field of automotive testing equipment, and in particular to a new energy vehicle energy consumption testing platform. Background Technology

[0002] New energy vehicles need to undergo energy consumption testing during the research and development and testing process. There are two types of energy consumption testing for new energy vehicles: actual road testing and bench testing. Actual road testing involves driving a new energy vehicle that meets the driving conditions on an actual road according to the test standards. Bench testing involves using a bench to support the wheels of the new energy vehicle, allowing the new energy vehicle to simulate driving conditions on the bench.

[0003] Different models of new energy vehicles have different wheelbases and track widths.

[0004] To accommodate different wheel tracks, longer rollers are typically used, eliminating the need for adjustments for new energy vehicles with different wheel tracks.

[0005] For new energy vehicles with different wheelbases, the spacing between the front and rear wheel support rollers needs to be adjusted. Although the existing frame facilitates the adjustment of the spacing between the support rollers, the vehicle passage bracket between the front and rear sets of support rollers needs to be removed and reinstalled every time the support roller position is adjusted, which is time-consuming and labor-intensive. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned problems in the existing technology and provide a new energy vehicle energy consumption test bench.

[0007] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0008] A new energy vehicle energy consumption test bench includes two sets of symmetrically arranged sliding groove mechanisms. Multiple parallel transverse connecting rods are installed between the two sets of sliding groove mechanisms. Each set of sliding groove mechanisms is equipped with two sets of roller frames for supporting the tires of new energy vehicles and two wedge blocks for the new energy vehicles to move up and down the energy consumption test bench. The front and rear sides of the roller frame at the front of the sliding groove mechanism are respectively connected to a first vehicle passage bracket and a comb-shaped second vehicle passage bracket. The front and rear sides of the roller frame at the rear of the sliding groove mechanism are respectively connected to a comb-shaped third vehicle passage bracket and a fourth vehicle passage bracket. The comb teeth of the third vehicle passage bracket are inserted into the comb teeth gaps of the second vehicle passage bracket. The two wedge blocks are respectively spliced ​​to the front end of the first vehicle passage bracket and the rear end of the fourth vehicle passage bracket.

[0009] The sliding mechanism includes a front sliding groove with a U-shaped cross-section, a rear sliding groove with a U-shaped cross-section, and two rectangular connecting plates. The front and rear sliding grooves are spliced ​​together, and the connecting blocks are connected to the front and rear sliding grooves respectively with first half-thread bolts.

[0010] The front slide groove has multiple evenly distributed circular through holes on the middle of its left and right sides. The roller frame at the front of the slide groove mechanism has multiple second half-thread bolts that pass through the circular through holes on its left and right sides. The rear slide groove has multiple evenly distributed strip-shaped through holes on the middle of its left and right sides. The roller frame at the rear of the slide groove mechanism has multiple third half-thread bolts that pass through the strip-shaped through holes on its left and right sides.

[0011] The roller frame includes a rectangular mounting plate, two symmetrical bearing seats, and two parallel roller shafts. The two bearing seats are respectively mounted on the left and right ends of the mounting plate with fourth-part threaded bolts. Each bearing seat has two sets of symmetrically arranged bearing mounting slots. Each set of bearing mounting slots includes at least three coaxial and parallel bearing mounting slots. A cylindrical bearing is installed in each bearing mounting slot. A bearing cap is installed on the bearing seat above each bearing mounting slot. The head of the roller shaft is fitted into the inner ring of the cylindrical bearing, and a roller for supporting automobile tires is welded to the middle of the roller shaft.

[0012] The bearing housing has two symmetrical right-angled trapezoidal protrusions at its top. The angle between the inclined surface of the protrusion and the top surface of the protrusion is 60°. The bearing mounting groove is located on the inclined surface of the protrusion. A semi-cylindrical clearance groove is also provided on the inclined surface of the protrusion.

[0013] The roller shaft has a limiting plane on one side of its head, and a limiting bolt is screwed onto the protrusion on one side of the clearance groove. The tail end of the limiting bolt can abut against the limiting plane.

[0014] The top ends of the first vehicle passage bracket, the second vehicle passage bracket, the third vehicle passage bracket, and the fourth vehicle passage bracket are located on the same horizontal plane.

[0015] In each of the slide mechanisms, the two sets of roller frames are parallel to each other, and the two wedge blocks in each of the slide mechanisms are arranged symmetrically.

[0016] The beneficial effects of this utility model are as follows: a comb-shaped second vehicle passage bracket is connected to the rear side of the roller platform located at the front of the chute mechanism, and a comb-shaped third vehicle passage bracket is connected to the front side of the roller platform located at the rear of the chute mechanism, so that the comb teeth of the third vehicle passage bracket are inserted into the comb teeth gaps of the second vehicle passage bracket. When adjusting the position of the roller platform located at the rear of the chute mechanism, the third vehicle passage bracket can be moved forward or backward relative to the second vehicle passage bracket, without the need to disassemble or assemble the second and third vehicle passage brackets.

[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] like Figures 1 to 11 As shown, a new energy vehicle energy consumption test bench includes two sets of symmetrically arranged sliding groove mechanisms 1. Multiple parallel transverse connecting rods 2 are installed between the two sets of sliding groove mechanisms 1, and the ends of the transverse connecting rods 2 are connected to the sliding groove mechanisms 1 by screws.

[0039] The sliding mechanism 1 includes a front sliding groove 101 with a U-shaped cross-section, a rear sliding groove 102 with a U-shaped cross-section, and two rectangular connecting plates 103. The front sliding groove 101 and the rear sliding groove 102 are spliced ​​together front and back. The connecting plates 103 are respectively connected to the front sliding groove 101 and the rear sliding groove 102 by first half-thread bolts 104.

[0040] Each set of slide mechanism 1 is equipped with two sets of roller frames 3 for supporting the tires of new energy vehicles, and the two sets of roller frames 3 in each slide mechanism 1 are parallel to each other.

[0041] Multiple evenly distributed circular through holes 105 are respectively opened in the middle of the left and right sides of the front slide groove 101. Multiple second half-thread bolts 9 passing through the circular through holes 105 are screwed onto the left and right sides of the roller frame 3 located at the front of the slide groove mechanism 1. When the second half-thread bolts 9 are tightened, the position between the roller frame 3 located at the front of the slide groove mechanism 1 and the front slide groove 101 is relatively fixed. When the second half-thread bolts 9 are unscrewed, the roller frame 3 located at the front of the slide groove mechanism 1 can be removed from the front slide groove 101.

[0042] Multiple evenly distributed strip-shaped through holes 106 are respectively opened in the middle of the left and right sides of the rear slide 102. Multiple third half-thread bolts 10 passing through the strip-shaped through holes 106 are screwed to the left and right sides of the roller frame 3 located at the rear of the slide mechanism 1. When the third half-thread bolts 10 are tightened, the position between the roller frame 3 located at the rear of the slide mechanism 1 and the rear slide 102 is relatively fixed. When the third half-thread bolts 10 are unscrewed, the roller frame 3 located at the rear of the slide mechanism 1 can move back and forth in the rear slide 102 to adjust its position.

[0043] The roller frame 3 includes a rectangular mounting plate 301, two symmetrical bearing seats 302, and two parallel roller shafts 303. The two bearing seats 302 are respectively mounted on the left and right ends of the mounting plate 301 with fourth half-thread bolts 304. Each bearing seat 302 is provided with two sets of symmetrically arranged bearing mounting slots. Each set of bearing mounting slots includes at least three coaxial and parallel bearing mounting slots 306. A cylindrical bearing 307 is installed in each bearing mounting slot 306. A bearing cap 308 is installed on the bearing seat 302 above each bearing mounting slot 306. The head of the roller shaft 303 is fitted into the inner ring of the cylindrical bearing 307, and a roller 309 for supporting automobile tires is welded to the middle of the roller shaft 303.

[0044] The axial length of roller 309 is 0.65 meters, the distance between two adjacent and coaxial rollers 309 is 1.2 meters, and the distance between the center points of two adjacent sets of roller stands can be adjusted between 2.3 meters and 3.3 meters, thereby meeting the energy consumption testing support requirements of new energy vehicles with a wheelbase between 1.3 meters and 1.8 meters and a wheelbase between 2.3 meters and 3.3 meters.

[0045] The distance between the two rollers 309 on the same set of roller testers 3 is 10 centimeters, so that the lower part of the tire of the new energy vehicle is located between the two rollers 309 on the same set of roller testers 3. This ensures that the tire of the new energy vehicle will not fall off between the two rollers 309 on the same set of roller testers 3, and also prevents the tire of the new energy vehicle from moving forward or backward between the two rollers 309 on the same set of roller testers 3 during the test.

[0046] The top of the bearing housing 302 is provided with two right-angled trapezoidal protrusions 305 that are symmetrical front and back. The inclined surface 305a of the protrusion 305 faces the upper part of the middle of the bearing housing. The angle between the inclined surface 305a of the protrusion 305 and the top surface of the protrusion 305 is 60°. The bearing mounting groove 306 is located on the inclined surface of the protrusion 305. The bearing mounting grooves 306 on the two protrusions 305 of the same bearing housing 302 are arranged facing each other. A semi-cylindrical clearance groove 3010 is also provided on the inclined surface 305a of the protrusion 305.

[0047] The bearing mounting groove 306 is set on the inclined surface of the protrusion 305. The protrusion 305 supports the force-bearing surface of the cylindrical bearing 307 installed in the bearing mounting groove 306, so that the force-bearing surface of the cylindrical bearing 307 has good coverage.

[0048] A limiting plane 303a is provided on one side of the head of the roller shaft 303. A limiting bolt 3011 is screwed onto the protrusion 305 on one side of the clearance groove 3010. A first screw hole 3012 communicating with the clearance groove 3010 is provided on the protrusion 305 on one side of the clearance groove 3010. The limiting bolt 3011 is screwed into the first screw hole 3012. The tail end of the limiting bolt 3011 can abut against the limiting plane 303a.

[0049] When a new energy vehicle is mounted or dismounted from the energy consumption test bench, the limiting bolt 3011 is rotated towards the limiting plane 303a, so that the tail end of the limiting bolt 3011 abuts against the limiting plane 303a, thereby preventing the roller shaft 303 from rotating freely. This prevents the tires of the new energy vehicle from slipping on the roller 309 when the new energy vehicle is mounted or dismounted from the energy consumption test bench.

[0050] When conducting energy consumption tests on new energy vehicles, the limiting bolt 3011 is rotated away from the limiting plane 303a, so that the tail end of the limiting bolt 3011 exits the relief groove 3010, thereby allowing the roller shaft 303 to rotate freely in the relief groove 3010.

[0051] The bearing housing 302 has a second screw hole 3013 on its side, and the second half-thread bolt 9 and the third half-thread bolt 10 are screwed into the second screw hole 3013 respectively.

[0052] The roller platform 3 located at the front of the chute mechanism 1 is connected to the first vehicle passage support 4 and the comb-shaped second vehicle passage support 5 on the front and rear sides respectively.

[0053] The first vehicle passage bracket 4 includes a first angle iron 401, a rectangular first base plate 402, and a rectangular first panel 403. The first angle iron 401 is screwed to the front of the mounting plate 301 of the roller frame 3 located at the front of the slide mechanism 1. The first base plate 402 is welded to the front end of the first angle iron 401. The first panel 403 is located above the first base plate 402 and is parallel to the first base plate 402. Multiple parallel first vertical square tubes 404 are welded between the first panel 403 and the first base plate 402, and between the first panel 403 and the first angle iron 401.

[0054] The second vehicle passage bracket 5 includes a second angle iron 501, a comb-shaped second base plate 502, and a comb-shaped second panel 503. The second angle iron 501 is screwed to the rear of the mounting plate 301 of the roller frame 3 located at the front of the slide mechanism 1. The second base plate 502 is welded to the rear end of the second angle iron 501. The second panel 503 is located above the second base plate 502 and is parallel to the second base plate 502. Multiple parallel second vertical square tubes 504 are welded between the second panel 503 and the second base plate 502, and between the second panel 503 and the second angle iron 501.

[0055] The roller platform 3 located at the rear of the chute mechanism 1 is connected to the front and rear sides of the third vehicle passage support 6 and the fourth vehicle passage support 7 in the shape of comb teeth.

[0056] The third vehicle passage bracket 6 includes a third angle iron 601, a comb-shaped third base plate 602, and a comb-shaped third panel 603. The third angle iron 601 is screwed to the front of the mounting plate 301 of the roller frame 3 located at the rear of the slide mechanism 1. The third base plate 602 is welded to the front end of the third angle iron 601. The third panel 603 is located above the third base plate 602 and is parallel to the third base plate 602. Multiple parallel third vertical square tubes 604 are welded between the third panel 603 and the third base plate 602, and between the third panel 603 and the third angle iron 601.

[0057] The fourth vehicle passage bracket 7 includes a fourth angle iron 701, a rectangular fourth base plate 702, and a rectangular fourth panel 703. The fourth angle iron 701 is screwed to the rear of the mounting plate 301 of the roller frame 3 located at the rear of the slide mechanism 1. The fourth base plate 702 is welded to the rear end of the fourth angle iron 701. The fourth panel 703 is located above the fourth base plate 702 and is parallel to the fourth base plate 702. Multiple parallel fourth vertical square tubes 704 are welded between the fourth panel 703 and the fourth base plate 702, and between the fourth panel 703 and the fourth angle iron 701.

[0058] The comb teeth 605 of the third vehicle passage bracket 6 are inserted into the comb tooth slot 505 of the second vehicle passage bracket 5. Specifically, the comb teeth of the third panel 603 are inserted into the comb tooth slot of the second panel 503, and the comb teeth of the third base plate 602 are inserted into the comb tooth slot of the second base plate 502.

[0059] When adjusting the position of the roller platform located at the rear of the chute mechanism, the third vehicle passage bracket can be moved forward or backward relative to the second vehicle passage bracket without disassembling or assembling the second or third vehicle passage bracket.

[0060] To improve the strength of the first panel 403, the second panel 503, the third panel 603, and the fourth panel 703, reinforcing ribs parallel to the long axis of the sliding mechanism are welded to the bottom of the first panel 403, the second panel 503, the third panel 603, and the fourth panel 703, respectively.

[0062] To facilitate the movement of the roller platform 3, the third vehicle passage bracket 6, and the fourth vehicle passage bracket 7 located in the rear slide groove, grease is applied to the bottom of the roller platform 3, the third vehicle passage bracket 6, and the fourth vehicle passage bracket 7.

[0063] When moving the roller platform 3, the third vehicle passage support 6, and the fourth vehicle passage support 7 located in the rear slide groove, they can be moved manually or towed by a vehicle and straps.
