Description

Technical Field

[0001] The utility model relates to the technical field of automobile design and manufacture, and more specifically, to a battery pack trial production cart matched with a two-column lifter. Background Art

[0002] In the prior art, most two-column lifts used in pilot workshops have raised connection plates to protect cables, etc. The raised connection plate in the middle of the two-column lift has a large raised height and angle. After the traditional pilot trolley is loaded with batteries, if it is not accelerated, it will be subject to the downward pressure of the battery pack and cannot cross the steps. If it is accelerated, the following consequences may occur:

[0003] ① When a single trolley is used to load the battery pack, after the movement accelerates, the rear wheels of the trolley are blocked by the raised connecting plate, the trolley tilts to one side, and bumps, generating a rollover torque, which can easily cause the battery pack to flip / slip, causing battery damage and personal injury;

[0004] ② Use two trolleys in series to load the battery pack. After the movement accelerates, the rear trolley is blocked by the raised connecting plate, tilts to one side and slips, directly causing the battery pack to flip / slip / damage, and personal injury;

[0005] ③ The traditional trial production trolley does not have a specially designed pusher, and the trial production personnel directly push the battery pack body, which poses a safety risk. Utility Model Content

[0008] Wherein, the top cover is welded and fixed to the upper ends of the support area and the telescopic obstacle crossing area.

[0009] Wherein, the push handle is screwed and fixed to the profile frame.

[0010] Wherein, the lower end of the profile column in the support area is welded and fixed to the pulley seat.

[0011] Wherein, the side profile support foot and the pulley seat are welded and fixed to form a side profile support foot assembly.

[0031] Example 1

[0032] like Figure 1-3 As shown, the battery pack trial production cart for the two-column lift of this embodiment includes a profile frame 101, side profile legs 102, middle profile legs 103, a push handle 104, a top cover 105, a pulley seat 106 and fasteners. The profile frame 101 includes a support area ( Figure 3 The left framed area in the middle) and the telescopic obstacle crossing area adjacent to the push handle 104 (such as Figure 3The framed area on the right side). There are two top covers 105, which are respectively welded and fixed to the upper ends of the support area and the telescopic obstacle crossing area. The push handle 104 is arranged on the upper end of one side of the profile frame 101, and the push handle 104 is screwed and fixed to the profile frame 101. The profile frame 101 is composed of a profile column and a profile beam. The lower end of the profile column in the support area is welded and fixed to the pulley seat 106. The pulley seat includes a pulley seat and a pulley. The side profile support foot 102 is welded and fixed to the pulley seat 106 to form a side profile support foot assembly, and the middle profile support foot 103 is welded and fixed to the pulley seat 106 to form a middle profile support foot assembly. The profile columns of the telescopic obstacle crossing area are longitudinally provided with three groups of profile through holes, and the side profile legs 102 and the middle profile legs 103 are longitudinally provided with three groups of leg through holes respectively, the side profile legs 102 and the middle profile legs 103 are connected by fasteners passing through the profile through holes and the leg through holes, and the heights of the side profile legs 102 and the middle profile legs 103 from the ground can be adjusted by adjusting the positions of the side profile legs 102 and the middle profile legs 103 relative to the profile columns.

[0033] In this embodiment, the middle profile support leg 103 and the side profile support leg 102 of the obstacle crossing area are retracted / extended respectively, and screwed and fixed, so that the cart can cross the raised connecting plate in steps. Figure 4 As shown, through simulation verification with a 95% standing dummy, when the trunk leans forward 15°, the human arm naturally extends and touches the push handle, which is convenient to use.

[0034] The implementation process of the battery pack trial production cart matched with the two-post lift in this embodiment is as follows:

[0035] ① Lift the vehicle, remove the power and discharge the liquid from the battery pack, disconnect the relevant pipes and lines, and meet the conditions for disassembling the battery pack. Push the trial cart under the battery pack (such as Figure 5 shown);

[0036] ② Lower the vehicle until the battery pack contacts the top cover of the trial cart (the two-column lifting block remains supported), and remove the battery mounting bolts (such as Figure 6 shown);

[0037] ③ Lift the vehicle body to the high station to separate the battery pack from the vehicle body, and keep only the trial production cart loaded with the battery pack at the low station (such as Figure 7 As shown), at this time, the front / rear column profiles of the telescopic obstacle crossing area are screwed and fixed with the side profile legs 102 and the middle profile legs 103;

[0038] ④ Remove all 4 M10 bolts of the middle profile support leg 103, move the support leg up 60mm, take a bolt from each of the left and right side support legs and insert it into any hole (insert but do not tighten, in this case, select the middle hole to insert), so that the middle profile support leg assembly can be retracted upward, and the cart moves forward until the middle profile support leg 103 crosses the raised connecting plate. At this time, the middle profile support leg 103 is in the retracted state, and the side profile support leg 102 is in the supporting state (such as Figure 8 shown);

[0039] ⑤ Take out the pre-pierced bolts on the left and right sides of the 103 middle profile support leg, lower the support leg to the ground, insert the M10 bolt into the profile column hole and tighten it. At this time, the side profile support leg 102 and the middle profile support leg 103 are both in the extended support state, and stand on both sides of the raised connection plate (such as Fig. 9 shown);

[0040] ⑥ Refer to step ④ to achieve the retraction of the side profile support leg 102 (such as Fig.10 shown);

[0041] ⑦ Push the cart forward and completely cross the raised connecting plate to make the battery pack out of the lifting range of the two-column stand (such as Fig.11 As shown, a forklift can be used to transfer the battery pack to the mounting bracket for placement; if it needs to be placed on the trial production cart for a long time, the side profile support legs 103 need to be adjusted to an extended support state and fully screwed and fixed).
