Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Reference Figures 1-6 A device for testing an automotive battery chassis includes a base 1, a first fixing component 2, and a testing component 4. The first fixing component 2 is fixedly connected to the base 1 to fix the automotive battery chassis 3. The testing component 4 includes a positioning rail 41, a sliding frame 42, and a roller balancing component 43. The positioning rail 41 is respectively installed on both sides of the automotive battery chassis 3. The sliding frame 42 is disposed above the positioning rail 41, and its two ends are slidably connected to the positioning rail 41. A plurality of testing rods 421 are provided on one side of the sliding frame 42. Each testing rod 421 has a roller 422 installed at its lower end. Before testing, the lowest point of all rollers 422 is kept at the same horizontal line. The rollers 422 roll along the surface of the automotive battery chassis 3 to test the flatness of its surface. The roller balancing component 43 is fixedly disposed on one side of the base 1 to correct the lowest point of all rollers 422 to the same horizontal line.

[0027] The base 1 has railings on both sides, with a handle at the top of one side of the railing. Each of the four corners of the base 1 has a caster wheel. Pulling the handle moves the caster wheels, thus moving the entire automotive battery chassis testing device. The base 1 has a detachable support base at its bottom. When the automotive battery chassis testing device is put into production, the detachable support base is assembled to secure the device to a designated location.

[0028] The first fixing component 2 has several parts, all located around the vehicle battery chassis 3.

[0029] Specifically, the first fixing component 2 includes: a fourth support member, a fifth support member, a sixth drive member, a sixth telescopic member, and a clamping member; the bottom end of the fourth support member is fixedly connected to the base 1, and the top end of the fourth support member is used to support the car battery chassis 3; the bottom end of the fifth support member is fixedly connected to the base 1, and the top end of the fifth support member is rotatably connected to the clamping member; one end of the sixth drive member is connected to the sixth telescopic member, and the sixth telescopic member is rotatably connected to one end of the clamping member; the other end of the clamping member is forked into three clamping claws, and the clamping member presses down on the car battery chassis 3 from above.

[0030] The sixth driving component is a linear motor. It drives the sixth telescopic component to move upwards, causing one end of the clamping component to tilt upwards. The clamping component and the fifth support component are rotatably connected. The other side of the clamping component presses downwards against the car battery chassis 3, while the bottom of the car battery chassis 3 is held in place by the fourth support component, thus fixing the car battery chassis 3. When the car battery chassis 3 is inspected and needs to be released, the sixth driving component drives the sixth telescopic component to move downwards, causing one end of the clamping component to move downwards. The clamping component and the fifth support component are rotatably connected, and the other side of the clamping component tilts upwards, moving away from the car battery chassis 3.

[0031] The detection rod 421 moves downward, thereby causing the roller 422 to move downward, so that the roller 422 contacts the top of the roller balancer 43, correcting the height of the roller 422 and keeping the lowest point of all rollers 422 corrected to the same horizontal line.

[0032] The sliding frame 42 slides along the positioning rails 41 on both sides of the car battery chassis 3, driving the rollers 422 to roll over the car battery chassis 3 to detect the flatness of the car battery chassis 3. When the rollers 422 roll over the depressions or protrusions on the car battery chassis 3, the detection rod 421 detects the depressions or protrusions and transmits the depression or protrusion signal to the operator so that the operator can process and repair the car battery chassis 3. When the depressions or protrusions on the car battery chassis 3 are within the specified range, the test is passed. When the rollers 422 roll over the smaller protrusions on the car battery chassis 3, the rollers 422 directly flatten the protrusions. The detection component 4 can perform small-range correction of the car battery chassis 3 while detecting.

[0033] By setting up the detection component 4, the flatness of the car battery chassis 3 is detected, which solves the problem that slight deformations of the car battery pack chassis that are difficult to be detected by the naked eye occur during the production and assembly of the car battery chassis, thereby reducing the stability and safety of the car.

[0034] like Figure 2 As shown, in some embodiments, the positioning rail 41 includes a slider 411 and a first slide rail 412 located on both sides of the top surface of the base 1. The lengths of the slider 411 and the first slide rail 412 are equal and parallel to each other. The length of the slider 411 is greater than the length of the car battery chassis 3.

[0035] The sliding member 411 and the first slide rail 412 ensure that the sliding frame 42 slides completely over the surface of the car battery chassis 3, allowing for a more comprehensive and thorough inspection of the flatness of the car battery chassis 3.

[0036] like Figure 3 As shown, in some embodiments, the center of the slider 411 is provided with a slot 4111, one end of the slider 411 is fixedly connected to a first driving member 4112, one end of the first driving member 4112 is connected to a first telescopic member 4113, and the first telescopic member 4113 passes through the slot 4111.

[0037] The length of the slot 4111 is greater than the length of the car battery chassis 3, so that the first driving member 4112 drives the first telescopic member 4113 to move in the slot 4111, thereby causing the sliding member 411 to slide across the car battery chassis 3.

[0038] like Figure 2 As shown, in some embodiments, the sliding frame 42 is fixedly connected to a second driving member 423, one end of the second driving member 423 is connected to a second telescopic member 424, one end of the second telescopic member 424 is fixedly connected to a fixing member 425, and at least two detection rods 421 are connected to the bottom of the fixing member 425.

[0039] The second driving member 423 drives the second telescopic member 424 to move the fixing member 425 up and down. The fixing member 425 drives the detection rod 421 up and down to avoid the first fixing component 2 at the edge of the car battery chassis 3. Specifically, there are 5 detection rods 421, which are connected to the fixing member 425 at equal intervals.

[0040] The detection rod 421 includes an outer rod and an inner rod. The top end of the inner rod is telescopically connected to the bottom end of the outer rod, and the bottom end of the inner rod is movably connected to a roller 422. An infrared distance sensor is fixedly connected inside the detection rod 421 to detect the distance of the inner rod. When the roller 422 rolls over an uneven area of ​​the car battery chassis 3, the roller 422 moves up and down, thereby driving the inner rod to move inside the outer rod. The infrared distance sensor determines whether the car battery chassis 3 has deformed by detecting the distance of the inner rod.

[0041] The design of fixing the infrared ranging sensor inside the outer rod allows the infrared ranging sensor to move together with the roller 422. The infrared ranging sensor and the inner rod remain relatively stationary. The infrared ranging sensor detects the distance to the inner rod, not the distance to the car battery chassis 3. Therefore, it is not affected by the reflectivity or surface material of the car battery chassis 3, making the infrared ranging sensor more accurate.

[0042] like Figure 2 and Figure 3 As shown, in some embodiments, one end of the sliding frame 42 is provided with a first sliding groove 426, and the first slide rail 412 is embedded in the first sliding groove 426; the other end of the sliding frame 42 is fixedly connected to a slider 427, and the slider 427 is fixedly connected to one end of the first telescopic member 4113, and the slider 427 and the slider 411 are slidably connected.

[0043] The first driving member 4112 drives the first telescopic member 4113, the first telescopic member 4113 drives the slider 427 to move along the slider 411, the slider 427 drives the sliding frame 42 to move, and the other end of the sliding frame 42 moves along the first slide rail 412. Through the setting of the slider 427 and the first slide groove 426, the balance and stability of the sliding frame 42 during the movement are maintained.

[0044] like Figure 1 and Figure 2 As shown, in some embodiments, a chain 5 is provided on one side of the slider 411. One end of the chain 5 is fixedly connected to the base 1, and the other end of the chain 5 is fixedly connected to the slider 427. The chain 5 winds back and forth as the slider 427 moves, and the arrangement of the chain 5 makes the movement of the sliding frame 42 more stable.

[0045] like Figure 1 and Figure 2 As shown, in some embodiments, an automotive battery chassis detection device further includes an alarm device 6 electrically connected to the detection rod 421, the alarm device 6 being provided with an alarm light 61.

[0046] The infrared ranging sensor transmits the measured distance signal to the alarm device 6. The alarm device 6 determines whether the distance exceeds the set error range of +2mm to -2mm, where -2mm means that the car battery chassis 3 is concave downward by 2mm and +2mm means that the car battery chassis 3 is protruding upward by 2mm. When the distance exceeds the set error range, the alarm device 6 drives the alarm light 61 to flash to remind the staff that the car battery chassis 3 being inspected has been deformed.

[0047] A device for testing the chassis of an automobile battery further includes a second fixing assembly, which comprises a second slide rail, a fifth driving member, a second support member, a third support member, and a fixing assembly. The second slide rail is fixedly connected to the other side of the top of the base 1. The fifth driving member is fixedly connected to the base 1, and one end of the fifth driving member is connected to a fifth telescopic member. The second support member and one end of the fifth telescopic member are fixedly connected. The bottom of the second support member is provided with a second slide groove that slides with the second slide rail. One side of the top of the second support member is provided with a third slide rail, and the other side of the top of the second support member is provided with a third support member. There is a fourth slide rail, which is perpendicular to the third slide rail; the fixed assembly includes a fourth driving member, a fourth telescopic member, and a clamping member. One end of the fourth driving member is connected to one end of the fourth telescopic member, and the other end of the fourth telescopic member is fixedly connected to one side of the clamping member. The other side of the clamping member is provided with a third sliding groove, which matches the third slide rail and the fourth slide rail. The clamping member is used to clamp the first coolant pipe 7; there are 4 fixed assemblies, of which the third sliding grooves of 2 fixed assemblies are slidably connected to the third slide rail in opposite directions, and the third sliding grooves of the other 2 fixed assemblies are slidably connected to the fourth slide rail in opposite directions.

[0048] The fifth driving member drives the fifth telescopic member, which in turn drives the second support member to slide along the second slide rail, so that the clamping member 113 and the first coolant pipe 7 are on the same plane. The fourth driving member drives the fourth telescopic member, which in turn drives the clamping member to move. Two clamping members clamp the first coolant pipe 7 from the top and bottom along the third slide rail, and the other two clamping members clamp the first coolant pipe 7 from the left and right along the fourth slide rail, thus completing the fixation of the first coolant pipe 7.

[0049] like Figure 1 and Figure 6As shown, in some embodiments, a device for testing an automotive battery chassis further includes an adjustment component 9. At least two adjustment components 9 are provided, wherein the two adjustment components 9 are arranged perpendicularly to each other around the first coolant pipe 7. A second coolant pipe 8 is fixedly connected to one side of the automotive battery chassis 3, and the first coolant pipe 7 is connected to the outside of the second coolant pipe 8. The adjustment component 9 is used to adjust the alignment of the first coolant pipe 7 with the second coolant pipe 8. The adjustment component 9 includes a third driving member 91, a third telescopic member 92, a housing 93, and a first support member 94. One end of the third driving member 91 is connected to one end of the third telescopic member 92. The housing 93 is fixedly connected to the outside of the third driving member 91, and one end of the housing 93 is fixedly connected to the first support member 94. The first support member 94 is fixedly connected to the base 1.

[0050] The third driving component 91 drives the third telescopic component 92, which pushes and corrects the first coolant pipe 7 from two mutually perpendicular directions, thus completing the correction of the first coolant pipe 7 and making the first coolant pipe 7 more accurately connected to the second coolant pipe 8.

[0051] The adjustment component 9 and the second fixing component are configured to make the connection between the first coolant pipe 7 and the second coolant pipe 8 more precise and tight, preventing leakage at the connection between the first coolant pipe 7 and the second coolant pipe 8.

[0052] A testing method based on the above-mentioned automotive battery chassis assembly testing device according to the present invention includes the following steps:

[0053] S1. Place the car battery chassis 3 on top of the base 1 and fix the car battery chassis 3 with the first fixing component 2;

[0054] The working principle of the first fixed component 2 in S1 is as follows: the sixth driving component drives the sixth telescopic component to move upward, the sixth telescopic component causes one end of the pressing component to tilt upward, the pressing component and the fifth support component are rotatably connected, the other side of the pressing component presses down on the car battery chassis 3, and the bottom of the car battery chassis 3 is held by the fourth support component, thereby fixing the car battery chassis 3.

[0055] Step S1 further includes: while the first fixing component 2 fixes the surface of the vehicle battery chassis 3, the driving adjustment component 9 is used to correct the first coolant pipe 7 so that the first coolant pipe 7 is aligned with the second coolant pipe 8, thus completing the fixing and correction of the vehicle battery chassis 3. The setting of the adjustment component 9 corrects the error existing at the connection between the first coolant pipe 7 and the second coolant pipe 8, preventing leakage at the connection between the first coolant pipe 7 and the second coolant pipe 8.

[0056] S2, drive the sliding frame 42, and all the rollers 422 of the detection rods 421 pass through the roller balancer 43 so that the lowest point of all the rollers 422 is kept on the same horizontal line;

[0057] The working process of the straightening roller 422 in S2 is as follows: the second driving member 423 drives the second telescopic member 424 to move downward by a set distance. The second telescopic member 424 drives the fixing member 425 to move downward. The fixing member 425 drives the detection rod 421 to move downward, thereby driving the roller 422 on the detection rod 421 to move downward, so that the roller 422 contacts the top of the roller balance member 43, and the height of the roller 422 is corrected, keeping the lowest point of all rollers 422 corrected to the same horizontal line.

[0058] S3. Continue to drive the sliding frame 42, and the roller 422 rolls along the surface of the car battery chassis 3. When the flatness of the surface of the car battery chassis 3 is detected to be greater than the set error range of -2mm to +2mm, the detection component 4 alarms; when the flatness of the surface of the car battery chassis 3 is detected to be less than the set error range of -2mm to +2mm, the car battery chassis 3 passes the test.

[0059] The specific working process of S3 is as follows:

[0060] 1) The second driving component 423 drives the second telescopic component 424 to move the detection rod 421 upward;

[0061] 2) The first driving member 4112 drives the first telescopic member 4113 to move the sliding frame 42 toward the direction of the car battery chassis 3 until the detection rod 421 on the sliding frame 42 is directly above the car battery chassis 3.

[0062] 3) The second driving member 423 drives the second telescopic member 424 to move the detection rod 421 downward until the roller 422 connected to one end of the detection rod 421 contacts the surface of the car battery chassis 3.

[0063] 4) The first driving member 4112 drives the first telescopic member 4113, the first telescopic member 4113 drives the sliding frame 42 to move, the sliding frame 42 drives the detection rod 421 to move, the detection rod 421 drives the roller 422 to roll on the car battery chassis 3 until the roller 422 rolls completely from one end of the car battery chassis 3 to the opposite end of the car battery chassis 3; when the roller 422 rolls over the protrusions or depressions on the car battery chassis 3, the roller 422 moves up or down, driving the inner rod to move up or down along the outer rod. The infrared ranging sensor transmits the position of the inner rod to the alarm device 6. The alarm device 6 determines whether the position of the inner rod exceeds the set error range of -2mm to +2mm. When the position of the inner rod exceeds the set error range, the alarm device 6 drives the alarm light 61 to flash to remind the staff that the car battery chassis 3 being tested has been deformed. Otherwise, the car battery chassis 3 passes the test.

[0064] 5) The second driving component 423 drives the second telescopic component 424, and the second telescopic component 424 drives the detection rod 421 to move upward;

[0065] 6) The first driving member 4112 drives the first telescopic member 4113, and the first telescopic member 4113 drives the sliding frame 42 to move towards the side closer to the roller balance member 43 until the roller 422 is directly above the roller balance member 43.

[0066] The efficiency of detecting the flatness of the car battery chassis 3 is improved by the cooperation of the first drive component 4112 and the second drive component 423.

[0067] First, the car battery chassis 3 is fixed by S1, and then the roller 422 is corrected by S2 to ensure the accuracy of the flatness detection of the car battery chassis 3 in S3.

[0068] Specific workflow:

[0069] The car battery chassis 3 is placed on the support of the first fixing component 2, and the clamping parts of the first fixing component 2 press and fix the car battery chassis 3 from above.

[0070] The fifth driving member drives the fifth telescopic member, which in turn drives the second support member to slide along the second slide rail, so that the clamping member 113 and the first coolant pipe 7 are on the same plane. The fourth driving member drives the fourth telescopic member, which in turn drives the clamping member to move. Two clamping members clamp the first coolant pipe 7 from the top and bottom along the third slide rail, and the other two clamping members clamp the first coolant pipe 7 from the left and right along the fourth slide rail, thus completing the fixation of the first coolant pipe 7.

[0071] Next, the third driving member 91 drives the third telescopic member 92, which pushes the first coolant pipe 7 from two mutually perpendicular directions to complete the fixing and correction of the first coolant pipe 7.

[0072] In the initial state, the roller 422 is located directly above the roller balancer 43 and is not in contact with the roller balancer 43. The second drive member 423 drives the second telescopic member 424, which in turn drives the detection rod 421 to move downward, so that the roller 422 contacts the top of the roller balancer 43, keeping the lowest point of all rollers 422 aligned with the same horizontal line.

[0073] Next, the second driving member 423 drives the second telescopic member 424, which in turn moves the detection rod 421 upward. The first driving member 4112 drives the first telescopic member 4113, which in turn moves the sliding frame 42 towards the car battery chassis 3 until the detection rod 421 on the sliding frame 42 is directly above the car battery chassis 3. The second driving member 423 then drives the second telescopic member 424, which in turn moves the detection rod 421 downward until the roller 422 connected to one end of the detection rod 421 contacts the surface of the car battery chassis 3. The first driving member 4112 then drives the first telescopic member 421... 113, the first telescopic member 4113 drives the sliding frame 42, the sliding frame 42 drives the detection rod 421 to move, the detection rod 421 drives the roller 422 to roll on the car battery chassis 3 until the roller 422 rolls completely from one end of the car battery chassis 3 to the opposite end of the car battery chassis 3; the second driving member 423 drives the second telescopic member 424, the second telescopic member 424 drives the detection rod 421 to move upward; the first driving member 4112 drives the first telescopic member 4113, the first telescopic member 4113 drives the sliding frame 42 to move towards the side close to the roller balance member 43 until the roller 422 is directly above the roller balance member 43.

[0074] As the roller 422 rolls on the car battery chassis 3, when it rolls over a protrusion or depression on the chassis 3, it moves up or down, causing the inner rod to move up or down along the outer rod. The infrared ranging sensor transmits the detected position of the inner rod to the alarm device 6. The alarm device 6 determines whether the position of the inner rod exceeds the set error range of -2mm to +2mm.
