Description
Technical Field
[0001] This utility model relates to the field of automotive technology, specifically to an automotive power installation structure. Background Technology
[0002] Electric vehicles are vehicles that use onboard power sources to drive their wheels with electric motors and meet all road traffic and safety regulations. Because they have a relatively smaller environmental impact compared to traditional vehicles, their future prospects are widely viewed favorably.
[0003] Electric vehicles are powered by batteries. Conventional battery packs are lifted and connected to the vehicle chassis frame by a lifting robotic arm, and then bolts and nuts are used to connect the battery pack to the chassis frame. During this process, the lifting robotic arm needs to continuously lift the battery pack until other robotic arms have completed the bolt and nut connection before it can retract. However, when the lifting robotic arm is in the center of the vehicle's underside, it affects the range of motion of other robotic arms, resulting in low battery pack installation efficiency. To address this issue, a new automotive power installation structure is proposed that can directly restrict the battery pack to the vehicle chassis, and then the lifting robotic arm can be immediately retracted without affecting the movement of other robotic arms. Utility Model Content
[0004] The purpose of this utility model is to provide an automotive power installation structure to solve the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: an automotive power installation structure, including a lower battery shell, a higher battery shell detachably mounted on the top of the lower battery shell via connecting bolts and connecting nuts, reinforcing ribs fixedly mounted on the outer sides of both the lower and upper battery shells, a battery pack and an electronic control module mounted inside the lower battery shell via a battery limiting bracket, and the outer wall of the lower battery shell detachably mounted to the automotive chassis frame via connecting components, wherein there are several connecting components arranged at equal intervals around the lower battery shell.
[0006] Preferably, the connecting assembly includes a side plate, which is fixedly installed to the outer wall of the battery lower casing by riveting bolts. A limiting seat is fixedly installed on the surface of the side plate. A connecting plate is movably installed on the inner side of the limiting seat via a hinge. A torsion spring is fitted on the outer side of the hinge. One end of the torsion spring presses against the limiting seat, and the other end of the torsion spring presses against the connecting plate. Connecting bolts and connecting nuts are inserted and installed inside the connecting plate. The connecting plate is detachably installed to the vehicle chassis frame via the connecting bolts and connecting nuts.
[0007] Preferably, the inner wall of the limiting seat is provided with a rubber pad, a screw is fixedly installed on the top of the rubber pad, and a locking nut is threaded to the outer side of the screw. The rubber pad can be detachably installed and removed from the limiting seat through the screw and the locking nut.
[0008] Preferably, the side plate has a mounting groove at its bottom, and L-shaped plates are fixedly installed on both sides of the inside of the mounting groove. A push spring is fixedly installed on the inner wall of the mounting groove, and a pressing plate is fixedly installed at the bottom of the push spring. The pressing plate extends downward to the outer side of the side plate, and right-angled triangular blocks are provided on both sides of the inclined surface of the pressing plate. A slide rod is fixedly installed on the side of the right-angled triangular block, and a tension spring is fixedly fitted on the outer side of the slide rod. The tension spring is located on the inner side of the L-shaped plate. A clamping plate is fixedly installed at the other end of the slide rod, and a clamping head is fixedly installed at the end of the clamping plate. The connecting plate has slots on both sides corresponding to the clamping heads.
[0009] Preferably, the side plate has a rectangular hole on its surface corresponding to the clamping plate, the clamping plate passes through the rectangular hole and extends to the outside of the side plate, and the connecting plate is engaged with the side plate by a clip and a slot.
[0010] Preferably, a protrusion is fixedly installed on the outer side of the L-shaped plate, and a sliding groove is provided on both sides of the extrusion plate. The protrusion is inserted into the sliding groove, and the extrusion plate is slidably connected to the bottom of the side plate through the protrusion and the sliding groove.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By installing a varying number of connecting components around the lower battery casing, the connecting plates in the connecting components are in a vertically folded and locked state. The lower and upper battery casings are lifted into the car chassis frame by a lifting robotic arm. Simultaneously, other power devices on the lifting robotic arm push the extrusion plate, which extrudes the right-angled triangular blocks on both sides. The sliding rod expands outward to both sides, and the tension spring is passively pulled open. The clamping plate also expands outward, and the clamping head at the end of the clamping plate leaves the slots on both sides of the side plate. Without the restriction of the clamping head, the torsion spring allows the connecting plate to rotate from vertical to horizontal and be restricted by the limiting seat. Afterward, when the lifting robotic arm moves down, the lower and upper battery casings sink slightly, and the connecting plates that unfold around the lower battery casing rest on the car chassis frame, thus restricting the position of the lower and upper battery casings. This also facilitates the installation of connecting bolts and connecting nuts by other robotic arms. Furthermore, there is no space restriction for the lifting robotic arm under the car chassis frame, which also improves the assembly efficiency of other robotic arms. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-2 This utility model provides a technical solution: an automotive power installation structure, including a lower battery shell 1, with a detachable upper battery shell 3 mounted on the top of the lower battery shell 1 via connecting bolts and connecting nuts 2. Reinforcing ribs 4 are fixedly installed on the outer sides of both the lower battery shell 1 and the upper battery shell 3 to improve the strength of the shells. Inside the lower battery shell 1, a battery pack and an electronic control module 6 are mounted via a battery limiting bracket 5. The battery pack and electronic control module 6 are references to existing technology, and will not be described in detail here. When using them, the preferred method can be chosen under the premise of meeting the driving conditions.
[0022] Please see Figures 1-2 The outer wall of the lower battery casing 1 is detachably installed to the vehicle chassis frame 8 via connecting components 7. There are several connecting components 7, which are arranged at equal intervals around the lower battery casing 1. The connecting components 7 can restrict the position of the battery pack and facilitate installation.
[0023] Please see Figures 3-7 The connecting assembly 7 includes a side plate 71, which is fixedly installed to the outer wall of the battery lower shell 1 by riveting bolts 72. A limiting seat 73 is fixedly installed on the surface of the side plate 71. A connecting plate 75 is movably installed on the inner side of the limiting seat 73 via a hinge pin 74. A torsion spring 76 is fitted on the outer side of the hinge pin 74. One end of the torsion spring 76 presses against the limiting seat 73, and the other end of the torsion spring 76 presses against the connecting plate 75. Connecting bolts and connecting nuts 77 are inserted and installed inside the connecting plate 75. The connecting plate 75 is detachably installed to the vehicle chassis frame 8 via the connecting bolts and connecting nuts 77. When the connecting plate 75 is torsioned by the torsion spring 76, the connecting plate 75 will rotate from an upright position to a horizontal position, during which the connecting plate 75 will press against the bottom of the limiting seat 73, ensuring that the connecting plate 75 does not rotate excessively.
[0024] Please see Figures 3-7 The inner wall of the limiting seat 73 is provided with a rubber pad 78, and a screw 79 is fixedly installed on the top of the rubber pad 78. A locking nut 710 is threaded onto the outer side of the screw 79. The rubber pad 78 is detachably installed to the limiting seat 73 through the screw 79 and the locking nut 710. After the connecting plate 75 is rotated horizontally, it will contact the rubber pad 78 under the limiting seat 73, ensuring that the connecting plate 75 will not wear or make abnormal noise due to force.
[0025] Please see Figures 3-7 The bottom of the side plate 71 is provided with a mounting groove 711. L-shaped plates 712 are fixedly installed on both sides inside the mounting groove 711. A push spring 713 is fixedly installed on the inner wall of the mounting groove 711. A pressing plate 714 is fixedly installed at the bottom of the push spring 713. The pressing plate 714 extends downward to the outer side of the side plate 71. Right-angled triangular blocks 715 are provided on both sides of the inclined surface of the pressing plate 714. A slide rod 716 is fixedly installed on the side of the right-angled triangular block 715. A tension spring 717 is fixedly fitted on the outer side of the slide rod 716. The tension spring 717 is located on the inner side of the L-shaped plate 712. A clamping plate 718 is fixedly installed at the other end of the slide rod 716. A clip head 719 is fixedly installed at the end of the clamping plate 718. Both sides of the connecting plate 75 are provided with slots 720 corresponding to the clip head 719. The extrusion plate 714 is extruded upwards, and the extrusion plate 714 will extrude the right-angled triangular blocks 715 on both sides to move aside. Then the clamping plate 718 and the clamping head 719 will move aside and open.
[0026] Please see Figures 3-7 The side plate 71 has a rectangular hole 721 on its surface corresponding to the clamping plate 718. The clamping plate 718 passes through the rectangular hole 721 and extends to the outside of the side plate 71. The cross-sections of the clamping head 719 and the clamping groove 720 are trapezoidal. By pressing the inclined surfaces of the trapezoids against each other, the clamping head 719 can be moved. The connecting plate 75 is engaged with the side plate 71 through the clamping head 719 and the clamping groove 720. When the clamping head 719 separates from the clamping groove 720, the connecting plate 75 is affected by the torsion spring 76 and rotates from vertical to horizontal.
[0027] Please see Figures 3-7 A protrusion 722 is fixedly installed on the outer side of the L-shaped plate 712. Slide grooves 723 are provided on both sides of the extrusion plate 714. The protrusion 722 is inserted into the slide groove 723. The extrusion plate 714 is slidably connected to the bottom of the side plate 71 through the protrusion 722 and the slide groove 723 to ensure that the extrusion plate 714 can slide stably up and down.
[0028] Working principle: By installing a varying number of connecting components 7 around the lower battery casing 1, the connecting plates 75 in the connecting components 7 are in a vertically folded and locked state. The lower battery casing 1 and the upper battery casing 3 are lifted up into the vehicle chassis frame 8 by a lifting robotic arm. Simultaneously, other power devices on the lifting robotic arm push the compression plate 714 upward. The compression plate 714 compresses the right-angled triangular blocks 715 on both sides, and the sliding rod 716 expands outward to both sides. The tension spring 717 is passively pulled open, and the clamping plate 718 also expands outward. The latches 719 at the ends of the clamping plates 718 will then disengage from the latches on both sides of the side plates 71. In slot 720, the connecting plate 75 is not restricted by the clamp 719. Its torsion spring 76 will rotate the connecting plate 75 from vertical to horizontal and restrict it by the limit seat 73. Afterwards, when the lifting robot arm moves down and returns, the lower battery shell 1 and the upper battery shell 3 sink down. The connecting plate 75 that unfolds around the lower battery shell 1 will rest on the car chassis frame 8, thereby restricting the position of the lower battery shell 1 and the upper battery shell 3. It also facilitates the installation of connecting bolts and connecting nuts 77 by other robots. Since there is no space restriction for the lifting robot arm under the car chassis frame 8, the assembly efficiency of other robots is also improved.
[0029] When the battery pack is disassembled later, the lifting robotic arm first lifts the lower battery shell 1 and the upper battery shell 3 a certain distance. Then, the connecting plate 75 is rotated from horizontal to vertical using a tool. During the rotation, the connecting plate 75 will compress the inclined surface of the clamp 719. The clamp 719 will expand outward and move a certain distance under the force. When the connecting plate 75 is fully upright, the tension spring 717 will cause the clamp 718 and the clamp 719 to retract back into their original positions. The clamp 719 will then insert into the slot 720, thereby locking the connecting plate 75. Without the restriction of the connecting plate 75, the lifting robotic arm can lift the battery pack down and move it away from the car chassis frame 8, thereby achieving rapid disassembly of the battery pack.
