At this time, the front slide 240 is connected to the front cross bar 230 by sliding along the left and right directions, which can provide the front positioning member 210 with freedom of movement along the left and right directions, and the front connecting column 250 is connected to the front slide 240 by sliding, which provides the front positioning member 210 with freedom of movement along the up and down directions, so that the front positioning member 210 first forms a structure for sliding positioning along the left and right directions with the base frame 100, and then a structure for sliding positioning along the up and down directions is arranged on this structure.

[0029] As for the specific structure of the front slide 240, in the first embodiment, it can be an integral body. At this time, a horizontal channel passing through the left-right direction and a vertical channel passing through the up-down direction are arranged on the front slide 240. When in use, the front cross bar 230 passes through the horizontal channel, and the front connecting column 250 passes through the vertical channel. A first screw passing through the horizontal channel and a second screw passing through the vertical channel are driven into the front slide 240. When it is necessary to adjust the position of the front connecting member left-right and up-down, loosen the first screw and the second screw. At this time, the front slide 240 and the front connecting column 250 can be adjusted and moved left-right and up-down respectively. After the adjustment is completed, tighten the first screw and the second screw so that the first screw is pressed against the outer side of the front cross bar 230, and the second screw is pressed against the outer side of the front connecting column 250. In this way, the movement and positioning of the front connecting member along the left-right and up-down directions can be realized.

[0030] As for the specific structure of the front slide 240, in the second embodiment, it can be a split structure, in which the front slide 240 is detachably connected with a first clamp block, a second clamp block and a third clamp block along the front-to-back direction, the first clamp block and the second clamp block form the above-mentioned horizontal channel, and the second clamp block and the third clamp block form the above-mentioned vertical channel, the front cross bar 230 is clamped in the horizontal channel directly by the clamping force of the first clamp block and the second clamp block when they are connected to each other, and the front connecting column 250 is clamped in the vertical channel by the clamping force of the second clamp block and the third clamp block when they are connected to each other, and as for the connection between the first clamp block, the second clamp block and the third clamp block, the third screw can be driven into the first clamp block to the second clamp block, so that the first clamp block and the second clamp block are locked and fixed to each other, and the fourth screw can be driven into the third clamp block to the second clamp block, so that the second clamp block and the third clamp block are locked and fixed to each other.

[0031] The left positioning component has a structure that can provide the rear positioning member 220 with movement in the up and down, left and right, and front and back directions. In the present embodiment, the left positioning component includes a rear cross bar 260, a left slide 270, a rear slide seat 280 and a rear connecting column 290. The rear cross bar 260 is arranged on the base frame 100. The left slide 270 can slide and position in the left and right directions between the front cross bar 230 and the rear cross bar 260.

The rear connecting column 290 can slide and position in the up and down directions on the rear slide seat 280. The rear positioning member 220 is connected to the bottom end of the rear connecting column 290. The front cross bar 230 and the rear cross bar 260 are relatively fixed on the base frame 100 along the front-to-back direction respectively. The left slide 270 is slidably connected between the front cross bar 230 and the rear cross bar 260, and can provide the rear positioning member 220 with freedom of movement in the left-to-right direction. The rear slide seat 280 is slidably connected to the rear left slide seat 270, and can provide the rear positioning member 220 with freedom of movement in the front-to-back direction. The rear connecting column 290 is slidably connected to the rear slide seat 280, and can provide the rear positioning member 220 with freedom of movement in the up-down direction, thereby realizing that the rear connecting member can be adjusted in three-dimensional directions of up-down, left-right, and front-to-back.

[0032] As for the left slide 270 and the rear slide 280, similar to the first embodiment of the front slide 240, channels may be formed on the front and rear sides of the left slide 270 to respectively position the front cross bar 230 and the rear cross bar 260, and then screws are driven into the left slide 270 to lock the front cross bar 230 and the rear cross bar 260. Similarly, two channels are formed on the front slide 240, and then screws are driven into the front slide 240 to lock the left slide 270 and the rear connecting column 290. Alternatively, similar to the second embodiment of the front slide 240, detachably connected split structures are respectively formed on the front and rear sides of the left slide 270 to clamp the front cross bar 230 and the rear cross bar 260. Similarly, detachably connected split structures are also formed on the rear slide 280 to clamp the left slide 270 and the rear connecting column 290.

[0033] In the above embodiment, the front cross bar 230 and the rear cross bar 260 can be directly fixed on the base frame 100, and in order to facilitate the overall movement of the entire left positioning assembly and the right positioning assembly, in this embodiment, the front cross bar 230 and the rear cross bar 260 can be moved and positioned in the up-down direction on the base frame 100. In this way, by moving the front cross bar 230 and the rear cross bar 260 in the up-down direction on the base frame 100, the left positioning assembly and the right positioning assembly can be directly adjusted up-down and positioned, which is more convenient to use. In addition, for the movable positioning structure of the front cross bar 230 and the rear cross bar 260, the first embodiment and the second embodiment of the front slide seat 240 can be directly referred to.

[0034] In actual applications, some sub-frames also need to be connected to sliding columns. In order to facilitate the connection and positioning of the sliding columns, the utility model also includes an upper positioning component, which includes an upper slide 310 and an upper slide seat 320. The upper slide 310 can move and be positioned in the left-right direction on the base frame 100, and the upper slide seat 320 can move and be positioned in the front-back direction on the upper slide 310. The top side of the upper slide seat 320 is provided with an installation groove, and the bottom of the installation groove is provided with a through hole 321. The upper slide 310 is connected to the base frame 100 by sliding along the left-right direction, and the upper slide seat 320 is connected to the upper slide 310 by sliding along the front-back direction. When connecting and fixing the slide column, the position of the upper slide 310 is adjusted along the left-right direction and the position of the upper slide seat 320 is adjusted along the front-back direction according to different types of sub-frames, so as to locate the installation position of the upper slide seat 320 relative to the sub-frame, and then the top end of the slide column is pre-positioned with respect to the through hole 321 of the upper slide seat 320, and then screws or bolts and other connecting parts are driven into the bottom of the installation groove to connect to the slide column, so as to lock and fix the slide column on the upper slide seat 320.

[0035] For the movable positioning and adjusting structure of the upper slide 310 and the upper slide seat 320 , reference may be made directly to the first embodiment or the second embodiment of the front slide seat 240 .

[0036] In actual applications, some subframes are also connected to control arms. In order to facilitate the connection and positioning of the control arms, such as Figure 2 As shown, in this embodiment, a connection block 330 is connected to the bottom side of the upper slide 320, and two connection ears 331 are formed at intervals along the horizontal direction on the bottom side of the connection block 330, and the connection blocks 330 are respectively connected to the positions on both sides of the through hole 321 on the bottom side of the upper slide 320. In each connection block 330, two connection ears 331 arranged at intervals can form a positioning gap. When fixing the control arm, the two ends of the control arm can be directly extended into the positioning gaps of the two connection blocks 330, and then the connection pieces can be driven into the connection ears 331 to position the control arm.

[0037] Furthermore, two upper positioning assemblies are symmetrically arranged along the left-right direction. The two positioning assemblies can be used to connect the sliding column and the control arm on the left and right sides of the sub-frame respectively.

[0038] When in use, the base frame 100 needs to be installed and fixed on the brake test bench. In order to facilitate its installation and positioning, the utility model also includes a fixing assembly, which includes a fixing seat 410 and a fixing plate 420. The fixing plate 420 can be moved and positioned in the left-right direction on the base frame 100. The fixing plate 420 is connected to the bottom side of the fixing seat 410. There are multiple fixing assemblies. The fixing seat 410 is slidably connected to the base frame 100 in the left-right direction, and can be connected to the brake test bench by using the fixing plate 420. When in use, the position of the fixing seat 410 can be adjusted according to different brake test bench structures, thereby adjusting the installation position of the fixing plate 420, which can further improve the overall versatility. For the movable positioning connection structure between the fixing seat 410 and the base frame 100, the setting of the first and second embodiments of the front slide seat 240 can be directly referred to.

[0039] The present invention further includes a reinforcement assembly, which includes a reinforcement seat 510 connected to the bottom of the base frame 100 at intervals along the front-to-back direction, and a reinforcement rod 520 connected between the reinforcement seats 510.
