DETAILED DESCRIPTION

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0036] The following combination Figures 1 to 7 The present invention describes a new energy vehicle metal connector interface aging test system and method.

[0037] In one embodiment, a new energy vehicle metal connector interface aging test system includes a test box 100, two positioning frames 200, two adjustment mechanisms 300, a packaging cover 400 and a functional component 500; a test cavity 110 is opened on the upper surface of the test box 100; the two positioning frames 200 are respectively fixed to the front and rear ends of the test box 100; the two adjustment mechanisms 300 are respectively located on both sides of the test box 100, and the two ends of the adjustment mechanisms 300 are respectively mounted on the two positioning frames 200; the packaging cover 400 is fixed to the upper surface of the test box 100 and is used to seal the test cavity 110; the functional component 500 is movably mounted on the packaging cover 400, and the functional component 500 and the end are located in the test cavity 110, and are used to inject hot and cold air into the test cavity 110; wherein, the cable portion of the metal connector interface is repeatedly inserted into the test box 100, and the bent portion is wrapped around the adjustment mechanism 300, and the metal connector interface is located in the test cavity 110.

[0038] The above-mentioned new energy vehicle metal connector interface aging test system sequentially passes the cable portion of the metal connector through the interior of the test box 100, such as passing the cable once from left to right and then from right to left. At this time, the bent portion of the cable is located at the side end of the test box 100. At this time, the bent portion of the cable is wrapped around the adjustment mechanism 300 so that the adjustment mechanism 300 can move the cable during operation, thereby driving the metal connector interface to move. The metal connector is then set in the test cavity 110, and the packaging cover 400 is fixed to the top of the test cavity 110, so that the test cavity 110 is in a closed state. The functional component 500 is then started to inject hot and cold air into the test cavity 110. At the same time, the adjustment mechanism 300 is started and the cable portion of the metal connector wrapped thereon is moved to assist in the aging test of the metal connector interface. This design scheme ensures that the testing process of the metal connector interface is not a single test, but is combined with the possible situations that the metal connector may encounter during actual use, and the testing effect is relatively better.

[0039] In one embodiment, the test cavity 110 is arranged in a semicircular structure, and the two ends of the test cavity 110 respectively pass through the front end and the rear end of the test box 100, and the side end of the test box 100 is provided with a plurality of first through holes 120 and a plurality of second through holes 130. The first through holes 120 are located directly below the second through holes 130, and the plurality of first through holes 120 and the plurality of second through holes 130 are spaced apart in the horizontal direction.

[0040] Specifically, the cable first passes through the first through hole 120, then bends toward the second through hole 130, and passes through the second through hole 130 into the test cavity 110. At this time, when the adjustment mechanism 300 moves the cable, the metal connector will also be driven to move. Combined with the hot and cold wind and other test processes in the aging test, the usage status of the metal connector can be effectively demonstrated.

[0041] In one embodiment, screw holes 160 are provided at the front and rear ends of the test box 100. The positioning frame 200 includes a baffle 210 and two side panels 220. The top of the baffle 210 is set as an arc surface. The two side panels 220 are respectively connected to the two sides of the baffle 210. The baffle 210 is installed in the screw holes 160 by bolts 230 to complete the fixation. The maximum distance between the two side panels 220 is greater than the width of the test box 100.

[0042] Specifically, after the top of the baffle 210 is set as an arc-shaped surface, the top width of the baffle 210 is smaller than the bottom width. Therefore, when subjected to force, the top of the baffle 210 will be deformed, while the baffle 210 can basically remain stable except for the top. A bevel block 211 is provided on the side of the top of the baffle 210 facing the test cavity 110, which is used to clamp and fix the packaging cover 400 when the packaging cover 400 is installed.

[0043] In one embodiment, a mounting groove 140 is further provided at the side end of the test box 100, and both ends of the mounting groove 140 respectively extend to the front end and the rear end of the test box 100. A plurality of limiting grooves 150 are further provided in the mounting groove 140, and the limiting grooves 150 are arranged in an arc-shaped structure, and the plurality of limiting grooves 150 are spaced apart from each other.

[0044] Specifically, the adjustment mechanism 300 includes a rotating rod 310, a fixed ring 320 and a shift rod 330; the rotating rod 310 is movably engaged in the mounting groove 140, and the two ends of the rotating rod 310 respectively pass through the two side plates 220, and the fixed ring 320 is movably engaged in the limiting groove 150, and the fixed ring 320 is sleeved on the rotating rod 310, and each fixed ring 320 is provided with a plurality of shift rods 330, and the plurality of shift rods 330 are arranged in a ring array, and the central axis of the shift rod 330 coincides with the radius of the rotating rod 310.

[0045] The cable is wound between two adjacent shifting rods 330 , and one end of the rotating rod 310 is transmission-connected to the driving end of the driving device. When in use, the driving device drives the rotating rod 310 to perform reciprocating motion, thereby shifting the cable.

[0046] In one embodiment, the packaging cover 400 includes a folding plate 410 and a plurality of positioning seats 420; both side ends of the folding plate 410 are bent on both sides, and the two side ends of the bent folding plate 410 are located above the middle position, the bottom end of the inclined block 211 overlaps the upper surface of the middle position of the folding plate 410, and the two side ends of the folding plate 410 overlap the upper surface of the test box 100, and the plurality of positioning seats 420 are arranged at intervals in the middle position of the folding plate 410 along the front-to-back direction of the test box 100, the interior of the positioning seat 420 is hollow, the bottom end of the positioning seat 420 is an open structure, and the side end of the positioning seat 420 is provided with a long hole 421.

[0047] Specifically, the packaging cover 400 further includes four end plates 430 , which are connected to both sides of the front and rear ends of the folding plate 410 . One side of the end plate 430 is bent and fits with the top of the baffle 210 .

[0048] In one embodiment, the functional component 500 includes a connecting tube 510, a sliding seat 520 and two bent tubes 530; the sliding seat 520 is movably clamped between two adjacent positioning seats 420, the connecting tube 510 is connected to the top of the sliding seat 520 and is connected to the interior of the sliding seat 520, and the two bent tubes 530 are movably clamped in two opposite long holes 421 respectively, one end of the bent tube 530 is connected to the positioning seat 420 and is connected to the interior of the positioning seat 420, and the other end of the bent tube 530 is bent downward.

[0049] Specifically, one end of the connecting pipe 510 away from the sliding seat 520 is connected to the main body of the aging test device, and is mainly used to provide the hot and cold, dry and wet environments required for the aging test.

[0050] In this embodiment, the aging test system is based on the calculation method of temperature change, and the calculation formula is as follows:

[0051] Aging time (A / B) DT / 10

[0052] A = actual number of days

[0053] B = aging factor (usually 2)

[0054] DT = Change from actual temperature to aging temperature

[0055] For example, if the actual temperature is 21°C and the aging temperature is 55°C, the aging time is calculated as follows:

[0056] Aging time = \frac{A\times B}{DT / 10} = \frac{365\times 2}{(55-21)}\div10 = 175\text{days}

[0057] In one embodiment, a method for aging test of a metal connector interface of a new energy vehicle is applied to the aging test system of a metal connector interface of a new energy vehicle according to any of the above embodiments, comprising the following steps:

[0058] The cable parts of the metal connector are sequentially inserted into the test box 100 , and the bent parts of the cables are located at both sides of the test box 100 .

[0059] The metal connector interface is disposed in the test cavity 110 , and the packaging cover 400 is fixed on the top of the test cavity 110 , so that the test cavity 110 is in a closed state.

[0060] The functional component 500 is started to inject hot and cold air into the test cavity 110 , and the adjustment mechanism 300 simultaneously moves the cable portion of the metal connector wound thereon to assist in the aging test of the metal connector interface.

[0061] In the above-mentioned aging test method for the metal connector interface of new energy vehicles, the cable portion of the metal connector is sequentially passed through the interior of the test box 100, such as passing the cable once from left to right and then from right to left. At this time, the bent portion of the cable is located at the side end of the test box 100. At this time, the bent portion of the cable is wrapped around the adjustment mechanism 300 so that the adjustment mechanism 300 can move the cable during operation, thereby driving the metal connector interface to move. The metal connector is then set in the test cavity 110, and the packaging cover 400 is fixed to the top of the test cavity 110, so that the test cavity 110 is in a closed state. The functional component 500 is then started to inject hot and cold air into the test cavity 110. At the same time, the adjustment mechanism 300 is started and the cable portion of the metal connector wrapped thereon is moved to assist in the aging test of the metal connector interface. This design scheme ensures that the testing process of the metal connector interface is not a single test, but is combined with the possible situations that the metal connector may encounter during actual use, and the testing effect is relatively better.

[0062] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
