Description

Technical Field

[0001] The utility model belongs to the technical field of new energy vehicle detection, and particularly relates to an adjustable intermediate support mechanism. Background Art

[0002] With the introduction of new energy vehicle testing standards, testing agencies in the automotive market need to add or renovate existing vehicle testing lines, upgrading from two-wheel drive chassis dynamometers to four-wheel drive chassis dynamometers, and the market demand is large.

[0003] Based on market demand, a corresponding four-wheel drive chassis dynamometer for new energy vehicles is developed. Since the models and wheelbases of new energy vehicles in the existing market are different, the four-wheel drive chassis dynamometer is required to have a wheelbase adjustment function.

[0004] At present, most new energy passenger cars are four-wheel drive, and the large difference in front and rear wheel speeds of some two-wheel drive passenger cars will lead to alarms and speed limits. In order to improve the applicability of chassis dynamometers, it is clarified that chassis dynamometers used for testing small and micro passenger cars are four-wheel drive with adjustable wheelbase.

[0005] However, since the wheelbase adjustment range is too large, in order to achieve the design load, an adjustable intermediate support mechanism needs to be added. When the wheelbase is shorter than a certain value, the width of the intermediate support mechanism is reduced; when the wheelbase is greater than a certain value, the width of the intermediate support mechanism is increased. Utility Model Content

[0006] In view of the problems raised by the above background technology, the purpose of the present utility model is to provide an adjustable intermediate support mechanism.

This structural design facilitates flipping and use.

[0012] The drive mechanism further comprises cylinders fixedly mounted on both sides of the top of the base, with the power output ends of the cylinders connected to adapter brackets, which are mounted at the center of the flap support mechanism. The connection between the cylinders and the adapter brackets is a bull's eye joint. This structural design facilitates the movement of the flap support mechanism.

[0013] The flap support mechanism further defines a sliding bracket having slides mounted on both sides of the bottom of the sliding bracket, the slides being slidably mounted on slide rails, a plurality of roller seats being mounted on the top of the sliding bracket, rollers being rotatably mounted within the roller seats, the plurality of rollers being in contact and corresponding contact with the plurality of trapezoidal support beams, an adjustment pad being mounted on the top of the sliding bracket, and the roller seats being mounted on the adjustment pads.

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1, as Figure 1 、 Figure 2 and Figure 3As shown, an adjustable intermediate support mechanism is installed on the front and rear sides of the top of the base 1, and the left and right sides of the slide rails 2 are slidably connected with the transverse movement components 3, and the tops of the left and right transverse movement components 3 are installed with comb-tooth support beams 4. The left and right comb-tooth support beams 4 are arranged in a relative structure, and the top center of the base 1 is installed with an intermediate support component 5, and the two sides of the intermediate support component 5 are hinged with flip-plate components 6. A driving mechanism 7 is also installed at the top center of the base 1, and the power output end of the driving mechanism 7 is connected to a flip-plate support mechanism 8. The flip-plate support mechanism 8 is slidably installed on the slide rail 2, and the flip-plate support mechanism 8 is arranged on the lower side of the flip-plate component 6.

[0025] In this embodiment, during use, when the wheelbase of the front and rear axles is greater than a certain value, the driving mechanism 7 is started, so that the driving mechanism 7 pushes the flap support mechanism 8 to slide along the slide rail 2 on the base 1, and the sliding flap support mechanism 8 pushes the flap assembly 6 to open the flap assembly 6 to supplement the gap between the comb-tooth support beam 4 and the middle support assembly 5. After the wheelbase of the front and rear axles is less than a certain value, the driving mechanism 7 drives the flap support mechanism 8 to reset, so that the flap assembly 6 is closed, leaving more space for the comb-tooth support beam 4 to continue to reduce the wheelbase, and the comb-tooth support beams 4 on the left and right sides can be inserted into each other's gaps to further reduce the wheelbase of the front and rear axles. The middle support assembly 5, when the wheelbase of the front and rear axles is within a certain range, serves to supplement the gap between the left and right comb-tooth support beams 4 and provides a connection and fixed position for the flap assembly 6.

[0026] Example 2, as Figure 1 and Figure 2 As shown, this embodiment adds the following structure on the basis of embodiment 1, the comb-tooth support beam 4 is locked and mounted on the transverse bracket 9 on the transverse moving assembly 3, a plurality of comb teeth 10 are evenly welded on the transverse bracket 9, and a plurality of comb teeth 10 are evenly welded and mounted on the transverse bracket 9, wherein the spacing between two adjacent comb teeth 10 is equal, the comb teeth 10 on the left and right sides are arranged in a staggered structure, and the ends of the comb teeth 10 are chamfered.

[0027] In this embodiment, the comb-tooth support beam 4 is welded by arranging square steel tubes to ensure that the comb teeth 10 on the left and right sides can be inserted into each other. A single comb tooth 10 is welded on the transverse bracket 9 to ensure welding strength. It ensures that the comb teeth 10 meet the load-bearing requirements when supported by the transverse bracket 9 and the intermediate support assembly 5 or the flap assembly 6, and the cantilever end of the comb teeth 10 is chamfered to facilitate the tire to enter.

[0028] Example 3, as Figure 3 、 Figure 4 and Figure 5 As shown, this embodiment adds the following structure on the basis of embodiment 1: the intermediate support assembly 5 includes a support frame 11, the support frame 11 is fixedly mounted on the base 1 by bolts, and a steel plate 12 is welded to the top of the support frame 11.

[0029] In this embodiment, the intermediate support assembly 5 is welded by a support frame 11 and a steel plate 12. The support frame 11 is fixed to the base 1 by bolts, and an adjustment pad can also be provided to adjust the overall height.

[0030] Among them, an anti-collision rubber pad can also be installed on the support frame 11 to ensure that when the flap assembly 6 is flipped down, the anti-collision rubber pad absorbs the impact of the flap, thereby achieving a protective effect.

[0031] Example 4, as Figure 3 and Figure 5 As shown, this embodiment adds the following structure on the basis of embodiment 1, the flap assembly 6 includes a flap mounting frame 13, the flap mounting frame 13 is welded by a plurality of square steel pipes, a flap 14 is welded and mounted on the surface of the flap mounting frame 13, a movable seat 15 is mounted on one side of the flap mounting frame 13, the movable seat 15 is hinged to an articulated seat 16, the articulated seat 16 is fixedly mounted on both sides of the top of the support frame 11, and a plurality of evenly arranged trapezoidal support beams 17 are mounted on the bottom of the flap mounting frame 13.

[0032] In this embodiment, the flap assembly 6 is welded by a flap mounting frame 13 and a flap 14, which ensures the supporting strength of the entire flap assembly 6. A trapezoidal support beam 17 is provided at the position corresponding to the flap support mechanism 8, which contacts the flap support mechanism 8. When the flap 14 reaches the horizontal level, the force is transferred to the flap support mechanism 8 through the lower plane of the trapezoidal support beam 17. When the flap 14 retracts, the flap support mechanism 8 contacts the oblique side of the trapezoidal support beam 17, and the flap can accelerate the retraction speed of the flap assembly 6 through gravity.

[0033] The flap assembly 6 is hinged to the hinge seat 16 through a movable seat 15, and the hinge seat 16 is fixedly mounted on the support frame 11 to ensure that when the flap assembly 6 is horizontal, the top flap 14 is at the same height as the middle support assembly 5, and the gap is minimal. When the flap assembly 6 flips down, the top flap 14 rotates without interfering with the comb teeth 10.

[0034] Example 5, as Figure 3 、 Figure 4 and Figure 5 As shown, this embodiment adds the following structure to the first embodiment: the drive mechanism 7 includes a cylinder 18 fixedly mounted on both sides of the top of the base 1. The power output end of the cylinder 18 is connected to an adapter 19, which is mounted at the center of the flap support mechanism 8. The connection between the cylinder 18 and the adapter 19 uses a bull's eye joint. This structural design facilitates the movement of the flap support mechanism 8.

[0035] In this embodiment, the cylinder 18 is fixed on the base 1, and the connection position between the cylinder 18 and the adapter frame 19 adopts a bull's eye joint, which eliminates the lateral force and only retains the push-pull force, and the adapter frame 19 is installed at the center position of the flap support mechanism 8, ensuring that the flap support mechanism 8 is evenly stressed when pushing / pulling back the flap support mechanism 8. At the same time, the cylinder serves as a driving component to ensure that there is sufficient push-pull driving force within the set air pressure range. The cylinder 18 is also equipped with a flow valve to ensure the running speed of the push-pull action. At the same time, the cylinder has its own buffer mechanism to ensure that the speed is slowly reduced at the beginning / end of the stroke, reducing the impact force of the entire system.

[0036] Example 6, as Figure 3 、 Figure 4 and Figure 5 As shown, this embodiment adds the following structure on the basis of embodiment 1, the flap support mechanism 8 includes a sliding bracket 20, and slides 21 are installed on both sides of the bottom of the sliding bracket 20. The slide 21 is slidably set on the slide rail 2. A plurality of roller seats 22 are also installed on the top of the sliding bracket 20, and rollers 23 are rotatably installed in the roller seats 22. The plurality of rollers 23 are in contact with and correspond to a plurality of trapezoidal support beams 17. An adjustment pad 24 is also provided on the top of the sliding bracket 20, and the roller seat 22 is installed on the adjustment pad 24.

[0037] The support rails 22 and 23 are connected to the support rails 21 to ensure that the entire support rail 20 moves forward and backward in a uniform manner. A roller 23 is installed on the top of the support rail 20, and an adjustment pad 24 is provided at the bottom of the roller 23 to ensure that the rollers 23 on the single-sided support mechanism are in full contact with the trapezoidal support beam 17. When driven out by the driving mechanism 7, the rollers 23 first contact the oblique sides of the trapezoidal support beam 17, pushing the flap 14 to flip upward. After reaching a certain height, the rollers 23 contact the lower plane of the trapezoidal support beam 17, so that the weight of the flap 14 is directly transferred to the slide 21 through the lower plane of the trapezoidal support beam 17, the rollers 23, the roller seats 22 and the sliding bracket 20. The entire force is vertically downward, ensuring that the flap assembly 6 will not be squeezed back by the flap support mechanism 8 due to excessive pressure, thereby causing the flap 14 to flip back.

[0038] The sliding seat 21 is a ball slider, which reduces the resistance to the movement of the support mechanism.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
