Description

Technical Field

[0001] The present invention relates to the field of anti-collision beam detection, and particularly to a detection device for an anti-collision beam of a new energy vehicle. Background Art

[0002] The strength detection of the anti-collision beam of a new energy vehicle usually uses the method of three-point bending test, which is a common experimental method for testing the bending mechanical properties of metals.

[0003] When the existing vehicle anti-collision beam strength detection equipment is working, it usually uses a single pressing block to press the vehicle anti-collision beam. However, in actual use, the vehicle anti-collision beam will be impacted at different positions and with different areas. The conventional detection equipment cannot quickly change the pressing position and the pressing area, resulting in too single detection results, which will affect the later improvement of the vehicle anti-collision beam.

[0004] In addition, as disclosed in Chinese Patent CN116337649A, a vehicle anti-collision beam bending test device cools the anti-collision beam by the water flow sprayed by a water pipe. Under the action of the water flow, the cooling after the anti-collision beam test can be accelerated, thereby reducing the waiting time required for the next bending test of the anti-collision beam. However, it still has defects: the position of the water flow scouring is fixed and cannot be adapted to press the anti-collision beam at different positions, resulting in an unsatisfactory cooling effect during the entire detection process. Summary of the Invention

[0005] In order to overcome the defect that the existing anti-collision beam detection equipment cannot quickly change the pressing position and the pressing area, the present invention provides a detection device for an anti-collision beam of a new energy vehicle.

[0006] The technical solution of the present invention is: a detection device for an anti-collision beam of a new energy vehicle, including a mounting frame and a moving component; the moving component is mounted on the mounting frame; it further includes a first telescopic driving member, a main pressing block, a second telescopic driving member and a side pressing block; the moving part of the moving component is provided with a first telescopic driving member and a pair of second telescopic driving members; the first telescopic driving member is located between the two second telescopic driving members; the telescopic end of the first telescopic driving member is mounted with a main pressing block for pressing the anti-collision beam downward; the telescopic end of the second telescopic driving member is provided with a side pressing block; when performing single-point pressing, the main pressing block is driven by the first telescopic driving member to press downward, and when performing large-area pressing, the side pressing blocks are driven by the second telescopic driving members to press downward synchronously, and the main pressing block and the side pressing blocks form a large-area pressing block.

[0007] To further explain, each of the two side pressure blocks has an inclined surface on its top facing the main pressure block, and a connecting frame is installed on the telescopic end of each of the two telescopic drive components; the two side pressure blocks are slidably disposed on the corresponding connecting frames; elastic elements are connected between the top of the opposing sides of the two side pressure blocks and the corresponding connecting frames; when the main pressure block is located between the two side pressure blocks, and the sides of the main pressure block and the side pressure blocks are in contact with each other, the elastic elements are in a stretched state.

[0008] To further explain, the main pressure block is provided with a water inlet and a water outlet, and a cavity channel is opened inside the main pressure block to connect the water inlet and the water outlet; the side pressure block is provided with a water inlet and a water outlet, and a cavity channel is opened inside the side pressure block to connect the water inlet and the water outlet.

[0009] To further explain, there are two water outlets, which are located on the two sides of the main pressure block facing the two side pressure blocks respectively.

[0010] To further explain, the second water outlet is located on the side of the side pressure block facing the main pressure block.

[0011] To further explain, the channel between the two water outlets is in the shape of a straight line and is located at the bottom of the main pressure block.

[0012] To further explain, a guide rail is provided below the main pressure block; two bases are slidably arranged on the guide rail; a connecting seat is installed on each base; a clamp for holding the end of the anti-collision beam is installed on each connecting seat; by adjusting the distance between the two bases, the two clamps can hold anti-collision beams of different lengths.

[0013] To further explain, each of the four corners of the base is equipped with a roller.

[0014] To further explain, the connecting seat and the corresponding clamp are connected by a rotating pin, and the opposite sides of the two connecting seats are respectively provided with arc surfaces.

[0015] To further explain, the bottom wall of the guide rail has multiple holes arranged in a straight line, and limit pins are installed at two holes respectively, so that the two limit pins are located on the outside of the two bases to limit the two bases.

[0016] The beneficial effects of the present invention are as follows: the present invention achieves rapid switching of applying pressure to different areas of the anti-collision beam by using the main pressure block and two side pressure blocks in combination.

[0017] This invention allows the second water outlet to follow the first main pressure block and move under the drive of the moving component. Therefore, the water flow from the second water outlet can cool the pressurized position of the anti-collision beam in real time, realizing synchronous movement of the water flow and targeted cooling.

[0018] This invention allows the spacing between the two clamps to be adapted to the length specifications of the anti-collision beam to be tested, thereby enabling the testing of anti-collision beams of different lengths. It also allows the clamps to rotate inward, and the base can move inward within the guide rail to form dynamic support, enabling micro-adjustment of the anti-collision beam during testing and providing buffer space for deformation and fracture of the anti-collision beam.

Detailed Implementation

[0026] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0027] Example 1: A new energy vehicle anti-collision beam testing device, such as Figures 1-6 As shown, it includes a mounting frame 1 and a moving component 2; the moving component 2 is mounted on the mounting frame 1; it also includes a telescopic drive component 3, a main pressure block 4, a second telescopic drive component 5, and a side pressure block 6; the moving part of the moving component 2 is provided with a first telescopic drive component 3 and a pair of second telescopic drive components 5, both of which are hydraulic push rods; the first telescopic drive component 3 is located between the two second telescopic drive components 5; the telescopic end of the first telescopic drive component 3 is equipped with the main pressure block 4; the telescopic end of the second telescopic drive component 5 is provided with the side pressure block 6.

[0028] The moving component 2 consists of a slide rail and an electric slider; the slide rail is mounted on the mounting bracket 1, and the telescopic drive component 1 3 and the telescopic drive component 2 5 are both connected to the electric slider.

[0029] The top of each of the two side pressure blocks 6 facing the main pressure block 4 is provided with an inclined surface 63, and the telescopic end of each of the telescopic drive components 5 is respectively equipped with a connecting frame 7; the two side pressure blocks 6 are respectively slidably disposed on the corresponding connecting frame 7; the top of the two side pressure blocks 6 facing each other and the corresponding connecting frame 7 are respectively connected with an elastic element 8, which is a spring.

[0030] The side pressure block 6 can only slide on the connecting frame 7, but cannot rotate.

[0031] The main pressure block 4 is provided with a water inlet 41 and a water outlet 42, and a cavity channel is opened inside the main pressure block 4; the side pressure block 6 is provided with a water inlet 61 and a water outlet 62, and a cavity channel is opened inside the side pressure block 6.

[0032] There are two water outlets 42, and the two water outlets 42 are respectively located on the two sides of the main pressure block 4 facing the two side pressure blocks 6.

[0033] The second water outlet 62 is located on the side of the side pressure block 6 facing the main pressure block 4.

[0034] The cavity channel inside the main pressure block 4 is generally inverted T-shaped, and the channel between the two water outlets 42 is straight and located at the bottom of the main pressure block 4.

[0035] Example 2: Based on Example 1, as follows Figures 1-6 As shown, a guide rail 9 is provided below the main pressure block 4; two bases 10 are slidably provided on the guide rail 9; a connecting seat 12 is installed on each base 10; a clamp 13 is installed on each connecting seat 12; the clamp 13 is composed of an upper clamping block and a lower clamping block, and the upper clamping block and the lower clamping block are fixed to each other by bolts to clamp the anti-collision beam.

[0036] Each of the four corners of the base 10 is equipped with a roller to facilitate the sliding of the base 10 within the guide rail 9.

[0037] The connecting seat 12 is connected to the corresponding clamp 13 by a rotating pin, and the opposite sides of the two connecting seats 12 are respectively provided with arc surfaces 121.

[0038] The bottom wall of the guide rail 9 has multiple holes arranged in a straight line, and limit pins 11 are installed at two holes respectively.

[0039] The invention is used as follows: First, the worker fixes both ends of the anti-collision beam to be tested between the upper and lower clamping blocks of the clamp 13 and secures them with bolts, with the impact-resistant surface of the anti-collision beam facing upwards. Depending on the length specifications of different anti-collision beams, the position of the base 10 in the guide rail 9 is pre-adjusted so that the distance between the two clamps 13 can be adapted to the length specifications of the anti-collision beam to be tested, thereby enabling the testing of anti-collision beams of different lengths. Two limiting pins 11 are fixed on the outside of the two bases 10 so that the two bases 10 will not move outwards, and the middle position of the fixed anti-collision beam is aligned with the bottom of the main pressure block 4.

[0040] The design of the arc surface 121 at the connecting seat 12 and the design of the connecting seat 12 and the corresponding clamp 13 connected by a rotating pin allow the clamp 13 to rotate inward. Combined with the design of the base 10 to move inward within the guide rail 9, dynamic support is formed, enabling the anti-collision beam to be finely adjusted during testing, and providing buffer space for the deformation and fracture of the anti-collision beam.

[0041] Next, a small-area pressure test is performed. First, the telescopic drive component 3 is controlled to push the main pressure block 4 downward, so that the lower end face of the main pressure block 4 contacts the anti-collision beam and applies a specified pressure to the anti-collision beam (the pressure is set according to the specific test standard), thereby achieving small-area pressure on the anti-collision beam. Then, the parts on its electric slider are controlled to move synchronously through the moving component 2 to move the position of the main pressure block 4, so that pressure can be applied to different positions of the anti-collision beam.

[0042] When the anti-collision beam is squeezed out of the dent by the main pressure block 4, the main pressure block 4 is prone to embedding and getting stuck in the dent. Therefore, before the telescopic drive component 1 3 pulls the main pressure block 4 up to move away from the anti-collision beam dent, the telescopic drive component 2 5 is first controlled to drive the side pressure block 6 down to contact the anti-collision beam, so that the two side pressure blocks 6 located on both sides of the main pressure block 4 can abut and limit the edge of the anti-collision beam dent. Then, the telescopic drive component 1 3 pulls the main pressure block 4 up to move away from the anti-collision beam dent, so that the main pressure block 4 embedded in the dent will not pull the anti-collision beam dent position to deform when it moves up, which makes it easier for workers to collect accurate dent data later.

[0043] During the process of applying small-area pressure to the anti-collision beam by moving the main pressure block 4 to different positions via the moving component 2, the pressure application area of ​​the anti-collision beam needs to be cooled. Therefore, water inlet 1 41 and water inlet 2 61 are connected to external water supply hoses beforehand. After the main pressure block 4 has applied small-area pressure to a certain position of the anti-collision beam, the telescopic drive component 1 3 is controlled to pull the main pressure block 4 upwards until the water outlet 2 62 is just exposed. Figure 5 As shown, water is supplied to inlet 41 and inlet 61 by an external water pump. Since outlet 42 is blocked by side pressure block 6, the water entering inlet 41 stays in the cavity of main pressure block 4 to absorb the heat inside main pressure block 4. The water entering inlet 61 flows out from outlet 62, thereby using the water flowing out from outlet 62 to cool the lower surface of main pressure block 4 and the anti-collision beam directly below main pressure block 4 under pressure. Since outlet 62 moves with main pressure block 4 under the drive of moving component 2, the water flow from outlet 62 can cool the pressured position of anti-collision beam in real time, realizing water flow following synchronous movement and targeted cooling.

[0044] When applying pressure over a large area to the crash beam, the main pressure block 4 and the two side pressure blocks 6 are made to form a single pressure block, such as... Figure 3 As shown, at this time, the telescopic drive component 3 and the telescopic drive component 5 operate simultaneously, allowing the main pressure block 4 and the two side pressure blocks 6 to apply pressure to the anti-collision beam synchronously, thereby achieving large-area pressure on the anti-collision beam. This allows for rapid switching of pressure on different areas of the anti-collision beam through the coordinated use of the main pressure block 4 and the two side pressure blocks 6. When the anti-collision beam is squeezed into a dent by the large-area pressure block formed by the main pressure block 4 and the two side pressure blocks 6, the main pressure block 4 and the two side pressure blocks 6 may become embedded and stuck in the dent. Therefore, at this time, the telescopic drive component 3 is first controlled to pull the main pressure block 4 upwards, moving it to the position of the inclined surface 63 of the side pressure block 6. The inclined surfaces 63 of the two side pressure blocks 6 are V-shaped. As the main pressure block 4 continues to move upwards along the inclined surface 63 of the side pressure block 6, the elastic element 8, initially in a stretched state, will pull the side pressure blocks 6, allowing them to slide within the connecting frame 7. The two side pressure blocks 6 move closer to each other. Figure 6 As shown, this allows the two side pressure blocks 6 to quickly come together, reducing the width of the overall pressure block formed by the main pressure block 4 and the two side pressure blocks 6. This allows the opposite sides of the two side pressure blocks 6 to detach from the recess of the anti-collision beam, enabling the main pressure block 4 and the two side pressure blocks 6 to easily move out of the recess of the anti-collision beam without causing pulling deformation to the recess of the anti-collision beam. This facilitates the subsequent collection of accurate recess data by workers.

[0045] After the test is completed, control the main pressure block 4 to move up and down, first as follows: Figure 4 As shown, expose the lower surface of the outlet 42 aligned with the side pressure block 6, and then... Figure 5As shown, water outlet 2 62 is exposed and aligned with the lower surface of the main pressure block 4, and the water pressure is appropriately increased so that the water sprayed from water outlet 1 42 washes the lower surface of the side pressure block 6, and the water sprayed from water outlet 2 62 washes the lower surface of the main pressure block 4, ensuring the cleanliness of the contact surface at the lower end of the pressure block.

[0046] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
