Description

Battery replacement shock absorbing structure TECHNICAL FIELD

[0001] The application belongs to the technical field of new energy heavy truck battery replacement, and specifically relates to a battery replacement shock absorbing structure. BACKGROUND

[0002] In recent years, new energy vehicles are increasingly appearing in people's field of vision, and battery replacement vehicles are one of them. When the battery is not fully charged to meet the driving demand, the full battery is directly replaced, which is a popular mode at present. The advantage of this is that it can save the time of waiting for charging and improve the utilization rate of the vehicle. For example, battery replacement heavy trucks are provided with a battery bottom support on the frame for loading battery replacement batteries, and the power supply battery replacement battery and the driving motor are electrically connected through the battery replacement connector arranged on the battery bottom support, so that the battery replacement heavy truck can obtain continuous power. In the field of battery replacement heavy trucks, the common battery replacement mode is the top hoisting type, that is, the battery replacement battery is hoisted from the top of the battery bottom support. When the battery replacement battery is loaded, the matching precision between the male and female battery replacement connectors is required to be high, so a guide positioning column is usually arranged on the battery bottom support to automatically calibrate the relative position of the male and female battery replacement connectors during the falling process of the battery replacement battery.

The bracket of the prior art is provided with a guide seat and a positioning pin, so that the battery replacement battery is automatically calibrated and aligned during the falling process. However, after the battery replacement battery is loaded on the electric vehicle, the bumping and vibration generated by the electric vehicle during driving will be transmitted to the battery replacement battery through the positioning pin. In addition to reducing the service life of the battery replacement battery, the hard-contact positioning pin and the positioning hole cannot guarantee the assembly precision in the worn state after being plugged in and out for many times.

The guide column 10 and the guide device 80 simultaneously elastically support the battery replacement battery 200, thereby increasing the buffering effect of the battery replacement battery 200. Embodiments of the application

[0043] A battery replacement shock absorption structure, as shown in Figure 1, comprises a battery replacement base 100 mounted on a battery replacement vehicle, a guide column 10 is arranged on the battery replacement base 100, a battery replacement battery 200 is mounted on the battery replacement base 100, the battery replacement battery 200 comprises a bottom frame 60 and a guide device 80 arranged on the bottom frame 60 and opening downward, the guide device 80 is arranged correspondingly with the guide column 10, the guide column 10 comprises a fixed mounting part 101 and a floating pin 11 mounted on the fixed mounting part 101, a first elastic part 103 is arranged between the floating pin 11 and the fixed mounting part 101, a first limiting part 14 is mounted on the lower end of the floating pin 11; and / or, as shown in Figures 11-14, the guide device 80 comprises a fixed sleeve 804 fixedly connected with the bottom frame 60, a floating positioning sleeve 805 partially arranged in the fixed sleeve 804 and elastically connected with the fixed sleeve 804, and a second elastic part 807 arranged between the fixed sleeve 804 and the floating positioning sleeve 805.

[0044] The guide column 10 and the guide device 80 can both adopt a semi-flexible structure, or one of them adopts a semi-flexible structure and the other adopts a rigid structure; wherein the semi-flexible structure keeps rigid guiding when the floating pin 11 and / or the floating positioning sleeve 805 does not have vertical displacement during the placement of the battery replacement battery 200, and has shock absorption effect in both horizontal and vertical directions when the floating pin 11 and / or the floating positioning sleeve 805 has vertical displacement. The rigid structure does not have displacement.

[0045] The guide column 10 on the battery replacement base 100 cooperates with the guide device 80 on the battery replacement battery 200 to guide and position the battery replacement battery 200. As shown in Figure 2, the battery replacement base 100 has a battery replacement bottom frame 20, a battery replacement connector 30 is arranged on the battery replacement bottom frame 20, and a plug-in piece 90 is correspondingly arranged on the bottom frame 60, so that the battery replacement connector 30 and the plug-in piece 90 can be precisely connected after the cooperation of the guide column 10 and the guide device 80, and further, a coarse guide structure 40 is preferably arranged on the battery replacement base 100, so that the guide column 10 and the guide device 80 can be preliminarily aligned after the coarse guide positioning of the coarse guide structure 40. As shown in Figure 10, a top frame 70 opposite to the bottom frame 60 is arranged on the battery replacement battery 200, and the top frame 70 is used for hoisting the battery replacement battery 200.

[0046] A plurality of buffer pads 50 are arranged between the battery replacement bottom frame 20 and the battery replacement battery 200, so that the vibration of the battery replacement battery 200 in the vertical direction is buffered and protected, but in the horizontal direction, since the battery replacement battery 200 is closely matched with the guide column 10, the impact load will be transmitted to the battery replacement battery when the battery replacement vehicle encounters a bumpy road during driving, so it is necessary to set the guide column 10 and / or the guide device 80 to have a shock absorption effect.

[0047] In order to achieve the above-mentioned purpose, the guide column 10 comprises a fixed mounting part 101 and a floating pin 11 mounted on the fixed mounting part 101, and a first elastic part 103 is arranged between the floating pin 11 and the fixed mounting part 101. The outer periphery of the fixed mounting part 101 is fixedly provided with a first mounting plate 12, and the fixed mounting part 101 can be fixedly mounted on the battery replacement bottom frame 20 through the through hole 120 provided on the first mounting plate 12, for example, by bolt connection. The floating pin 11 has a guide part 111 extending upward from the fixed mounting part 101, the diameter of the guide part 111 gradually decreases from bottom to top, and the floating pin 11 further comprises a transverse through hole 110 arranged close to the guide part 111, through which force can be better applied during the installation of the floating pin 11. Similarly, the first limiting part 14 is also provided with an assembly hole 141, which is preferably a plurality of assembly holes 141, and the first limiting part 14 can be more easily assembled to the floating pin 11 by grabbing the assembly hole 141. Preferably, a first mounting hole 114 is provided through the center of the first limiting part 14; the diameter of the guide part 111 gradually decreases from bottom to top, or in some embodiments, the upper end of the guide part 111 is conical and the lower end is cylindrical, which matches the guide device 80 at the bottom of the battery replacement battery 200.

[0048] As shown in FIGS. 11-14, the floating positioning sleeve 805 is sleeved on the guide column 10, and through the buffering of the second elastic part 807, the impact on the bottom frame 60 and the battery replacement battery 200 with the bottom frame 60 from the battery replacement seat 100 can be avoided, and the effect of shock resistance and shock absorption can be achieved. Preferably, the second elastic part 807 can be integrated with the fixed sleeve 804 and the floating positioning sleeve 805 by vulcanization means using rubber, and in other embodiments, materials with similar elasticity can also be used, for example, springs can be used to detachably connect the fixed sleeve 804 and the floating positioning sleeve 805, etc., which will not be described here.

[0049] As shown in FIGS. 3 and 4, before the battery replacement battery 200 is installed to the battery replacement seat 100, the first limiting part 14 has a first position matched with the inner wall of the fixed mounting part 101, and when the first limiting part 14 is in the first position, the first limiting part 14 is in close contact with the inner wall of the fixed mounting part 101, which can prevent the floating pin 11 from shaking horizontally relative to the fixed mounting part 101; after the battery replacement battery 200 is installed to the battery replacement seat 100, the floating pin 11 bears part or all of the weight of the battery replacement battery, thereby generating a downward displacement, so that the first limiting part 14 has a second position separated from the fixed mounting part 101, and when the first limiting part 14 is in the second position, the lower end of the floating pin 11 is no longer constrained in the horizontal direction, so that the floating pin 11 can shake horizontally relative to the fixed mounting part 101 within a local range.

[0050] The first elastic part 103 drives the first limiting part 14 to reset from the second position to the first position after the battery 200 leaves the battery base 100. Preferably, the first elastic part 103 provides an upward pre-tightening force to the floating pin 11 before the battery 200 is mounted on the guide column 10, and the floating pin 11 is pushed to move downward during the process of mounting the battery 200 on the guide column 10, thereby increasing the pre-tightening force. When the battery 200 leaves the battery base 100, the first elastic part 103 rebounds, thereby driving the first limiting part 14 to reset from the second position to the first position. Obviously, in other embodiments, the first elastic part 103 can not provide a pre-tightening force before the battery 200 is mounted on the guide column 10, as long as the first elastic part 103 is deformed during the falling process of the battery 200 to provide a rebound force, which will not be described in detail.

[0051] As shown in FIGS. 6-9, the maximum transverse dimension of the first limiting part 14 is greater than the minimum inner diameter of the fixed mounting part 101. The purpose of this design is that the floating pin 11 can move downward relative to the fixed mounting part 101 in the initial state, but cannot move upward relative to the fixed mounting part 101, that is, the floating pin 11 cannot be pulled out of the fixed mounting part 101, that is, the floating pin 11 of the present application has a pull-out prevention effect, avoiding the risk of difficulty in pulling out the battery 200 or loosening the positioning pin or even pulling out the battery base 100.

[0052] As shown in FIGS. 7 and 8, the first limiting part 14 includes a nested part 143 matched with the inner side or outer side of the fixed mounting part 101 and a blocking part 142 aligned with the bottom of the fixed mounting part 101. The nested part 143 and the blocking part 142 are generally convex structures or concave structures, and are in a fitting form with the fixed mounting part 101. When the floating pin 11 pushes the first limiting part 14 downward under the action of gravity of the battery 200, the nested part 143 and the blocking part 142 are separated from the fixed mounting part 101. Preferably, the nested part 143 is provided with a chamfer (not shown) for better resetting.

[0053] The fixed mounting part 101 is internally provided with a movable mounting sleeve 102 fixedly integrated with the first elastic part 103, and the lower end of the floating pin 11 is detachably connected with the movable mounting sleeve 102. The advantage of this design is that the movable mounting sleeve 102, the elastic part 103 and the fixed mounting part 101 can be integrated first, then the first mounting part 112 at the lower end of the floating pin 11 is mounted on the movable mounting sleeve 102, and finally the first limiting part 14 is mounted on the second mounting part 113 at the end of the floating pin 11. Preferably, the first limiting part 14 is provided with a first mounting hole 114, and the first mounting hole 114 and the second mounting part 113 are detachably connected in a threaded connection manner, which is helpful for later maintenance. In other embodiments, the movable mounting sleeve 102 and the first limiting part 14 can be fixedly connected as a whole, and only the floating pin 11 is mounted on the movable mounting sleeve 102, or the floating pin 11, the movable mounting sleeve 102 and the first limiting part 14 are fixedly assembled as a whole by a threaded connection or the like.

[0054] The first elastic part 103 is a rubber sleeve, the inner side of the first elastic part 103 is vulcanized with the outer side of the movable mounting sleeve 102, and the outer side of the first elastic part 103 is vulcanized with the inner side of the fixed mounting part 101. In other embodiments, the first elastic part 103 can also be made of a spring or other elastic material.

[0055] As shown in FIG. 5, the first limiting part 14 extends upward, the lower end of the floating pin 11 is detachably connected with the first limiting part 14, and the first elastic part 103 is arranged between the first limiting part 14 and the fixed mounting part 101. Compared with the first embodiment, one movable mounting sleeve 102 can be reduced, or the movable mounting sleeve 102 in the first embodiment can be considered as a part of the first limiting part 14 in the second embodiment. In the second embodiment, the bottom of the floating pin 11 can be provided with a bolt, and the upper end of the first limiting part 14 can be provided with an internal thread counterbore matched with the bolt, so as to realize the detachable connection. Obviously, a protrusion can also be arranged on the first mounting part 112 at the lower end of the floating pin 11, and a groove can be arranged in the first limiting part 14, and the same technical effect can be achieved by the buckle cooperation of the protrusion and the groove, which will not be described here.

[0056] The second limiting part 15 is arranged between the fixed mounting part 101 and the floating pin 11 on the upper side of the first limiting part 14, and includes a limiting block 151 arranged between the fixed mounting part 101 and the floating pin 11 and a flexible connecting part 152 extending outward from the limiting block 151 to cover the upper end of the fixed mounting part 101. The limiting block 151 can be made of flexible, rigid or rigid-flexible materials, and can limit the movement range of the floating pin 11. The flexible part 152 covers the upper end of the fixed mounting part 101 from inside to outside, so that the gap between the limiting block 151 and the fixed mounting part 101 is not exposed, thereby achieving the effect of dust and water prevention. Preferably, the limiting block 151 and the flexible part 152 are integrated, and the second limiting part 15 is detachably connected to the movable mounting sleeve 102, for example, by screw connection or interference fit.

[0057] As shown in FIG. 9, the first limiting part 14 is not in a cylindrical shape but in a long strip shape. The second mounting part 113 of the floating pin 11 is provided with a clamping groove 115 for mounting the first limiting part 14. The first limiting part 14 is fixedly connected to the floating pin 11 by a pin 116. Preferably, the lower end of the fixed mounting part 101 is provided with two limiting grooves 104, and the two ends of the first limiting part 14 are respectively limited in the two limiting grooves 104. That is, the maximum transverse dimension of the first limiting part 14 is greater than the minimum inner diameter of the fixed mounting part 101. Therefore, in the sixth embodiment, the floating pin 11 still has the technical effect of preventing being pulled out.

[0058] Further, in order to achieve better buffering and damping effect, the second elastic part 807 can be deformed in the horizontal direction and the vertical direction and provide a rebounding force. Before the guide column 10 is inserted into the positioning hole 802 of the floating positioning sleeve 805, the floating positioning sleeve 805 has a first position in contact with the fixed sleeve 804. After the guide column 10 is inserted into the positioning hole 802 of the floating positioning sleeve 805, the floating positioning sleeve 805 has a second position separated from the fixed sleeve 804. When the floating positioning sleeve 805 is in the first position, the floating positioning sleeve 805 is relatively fixed with the fixed sleeve 804, that is, before the guide column 10 is inserted into the guide device 80, the floating positioning sleeve 805 is fixed relative to the battery swap battery 200, and the floating positioning sleeve 805 can have a good guiding and positioning effect. When the battery swap battery 200 is completely mounted on the battery swap base 100, the floating positioning sleeve 805 moves upward under the push of the guide column 10 and leaves the fixed sleeve 804, and the second elastic part 807 deforms at the same time. At this time, the weight of the battery swap battery 200 is borne by the buffer pad 50 on the battery swap base 100, and the buffer pad 50 and the guide device 80 can provide damping and anti-impact effect in the horizontal direction when the battery swap battery 200 moves relative to the battery swap base 100.

[0059] Preferably, the second elastic part 807 provides a pre-tightening force to keep the floating positioning sleeve 805 in abutment with the fixed sleeve 804 when the floating positioning sleeve 805 is in the first position, that is, the second elastic part 807 is preferably designed to produce a small amount of deformation when the floating positioning sleeve 805 is in the first position, and to produce more deformation when the battery 200 is completely seated on the battery replacement base 100. In addition to providing a resilient force to the floating positioning sleeve 805, the second elastic part 807 can also ensure that the floating positioning sleeve 805 remains relatively fixed with the fixed sleeve 804 without being affected by external forces.

[0060] The fixed sleeve 804 has a hollow cylindrical first cylindrical part 808, and the floating positioning sleeve 805 has a hollow cylindrical second cylindrical part 809, which is located in the inner hole of the first cylindrical part 808. A gap 806 for the second elastic part 807 is left between the first cylindrical part 808 and the second cylindrical part 809, which is the buffer active area of the floating positioning sleeve 805. The floating positioning sleeve 805 also includes an abutment plate 810 with a transverse dimension not less than the diameter of the inner hole of the first cylindrical part 808. The advantage of this design is that when the guide column 10 exits the guide device 80, that is, when the battery 200 leaves the battery replacement base 100, the floating positioning sleeve 805 is ensured not to be pulled out of the fixed sleeve 804 along with the guide part 111, achieving the effect of preventing pulling out.

[0061] The abutment plate 810 is provided at the upper end of the second cylindrical part 809, and the lower end of the second cylindrical part 809 has a gradually open trumpet-shaped opening to facilitate the entry of the guide part 111 with a conical top and complete the guide. In order to achieve better positioning and prevent pulling out, as shown in FIGS. 15 and 16, the abutment plate 810 is provided with a stepped part 811 nested with the inner hole or outer periphery of the fixed sleeve 804. The stepped part 811 preferably has a taper, which is beneficial to the resetting of the floating positioning sleeve 805.
