Description

Technical Field

[0001] This utility model relates to the field of heavy-duty truck battery swapping technology, specifically a guide assembly for a new energy heavy-duty truck on-board battery swapping system. Background Technology

[0002] New energy batteries have become the mainstream choice due to their safety and long cycle life, and their system energy density is constantly improving to support longer driving range. To cope with the high load demands of heavy trucks and to compensate for the short charging time, battery swapping technology is maturing as an important supplementary solution, enabling rapid energy replenishment.

[0003] Currently, the mainstream pure electric heavy-duty truck battery swapping system mainly adopts top-mounted battery swapping. In existing battery swapping systems, the guide structure usually uses multiple guide pins to position the battery box and the base. However, during the top-mounted battery swapping process, due to the extremely heavy weight of the battery box carrying the battery pack, the battery box is prone to swaying due to inertia. When the guide pins and pin holes are connected, they will inevitably collide with the bottom frame of the battery box. The impact force acts on the guide pins, which can easily cause the guide pins to deviate in posture, resulting in lateral or longitudinal deviations when the battery pack is connected to the base, thus reducing the success rate of battery swapping. Utility Model Content

[0004] The purpose of this invention is to provide a guiding assembly for a new energy battery swapping heavy-duty truck on-board battery swapping system to solve the above-mentioned problems.

[0005] The technical solution of this utility model is: A guide assembly for a new energy battery swapping heavy-duty truck-mounted battery swapping system, comprising a base and a battery box detachably mounted on the base, including: a first guide mechanism comprising multiple primary guide seats, each disposed inside each vertex of the base, for initially guiding the battery box into the base, achieving initial docking between the battery box and the base, and distributing lateral loads caused by battery box swaying; multiple first mating parts, each disposed inside each vertex of the bottom frame of the battery box, with the multiple first mating parts corresponding one-to-one with the positions of the multiple primary guide seats and mating with the primary guide seats; a third guide mechanism comprising: a first guide mechanism comprising: a first guide mechanism comprising multiple primary guide seats, each disposed inside each vertex of the bottom frame of the battery box, the first guide parts corresponding one-to-one with each primary guide seat and mating with the primary guide seats; a fourth guide mechanism comprising: a first ... The two guiding mechanisms include: two secondary guide seats, respectively arranged along two diagonals of the base on the base, and the two secondary guide seats are located below the plurality of primary guide seats; two second mating parts, disposed on the bottom frame of the battery box, and the positions of the two second mating parts correspond one-to-one with the positions of the two secondary guide seats, and are inserted into the two secondary guide seats; and a locking assembly, including: a pneumatic positioning pin and a positioning pin hole that mates with the pneumatic positioning pin, the pneumatic positioning pin being connected to the vehicle's air source, the pneumatic positioning pin being disposed on the inner side of the base, and the positioning pin hole being disposed on the inner side of the bottom frame.

[0006] The four primary guide seats are positioned higher than the two secondary guide seats. When the battery box and the base are docked, the primary guide seats first enter for rough positioning. After the first mating part's engagement limiting surface fully enters the primary guide seat, the second mating part and the two secondary guide seats complete the insertion. Then, the pneumatic positioning pin of the locking assembly extends and inserts into the positioning pin hole, thereby enabling the female and male battery swapping connectors to be quickly and accurately aligned, ensuring the smooth operation of the battery swapping connector assembly.

[0007] Furthermore, each of the first-level guide seats includes: a guide body, which is a corner plate structure, with two plates of the corner plate structure respectively fixedly connected to the frame of the base; an inclined transition part, including two inclined plates, respectively connected to the top ends of the two plates of the corner plate structure, and both inclined towards the inside of the base; a flat end panel, which is arranged parallel to the base and connected between the top ends of the two inclined plates; each first mating part includes: a mating plate of the corner plate structure, with two plates of the mating plate structure respectively fixedly connected to both sides of the apex of the battery box.

[0008] Furthermore, a first reinforcing plate is fixedly connected between the two plates of the guide body. The first reinforcing plate is an angular structure cut diagonally from a rectangular tube profile, and the outer wall of the first reinforcing plate is fixedly connected to the inner wall of the guide body.

[0009] Furthermore, both plates of the guide body are provided with square grooves. Guide pads are fixedly connected to the top and bottom walls of the square grooves. A limiting spring plate is also provided in the square groove. The limiting spring plate is an arc-shaped spring plate, which includes an arc-shaped part and a straight mounting part connected to both ends of the arc-shaped part. The mounting part at one end is fixedly connected to the guide pad at the top of the square groove by screws. The arc-shaped part protrudes from the square groove, and the mounting part at the other end abuts against the guide pad at the bottom of the square groove.

[0010] Furthermore, the second mating part is a fixing plate with a pin hole, the fixing plate is fixedly connected to the crossbeam of the bottom frame of the battery box, and each of the secondary guide seats includes: a guide pin, which matches the size of the pin hole; and a guide support, which is set on the crossbeam of the bottom support, and the guide pin is vertically connected to the guide support.

[0011] Furthermore, the guide support includes: a first support plate and a third support plate arranged in parallel, and a second support plate connected between the first support plate and the third support plate. The third support plate is fixedly connected to the crossbeam of the base support. Limiting through holes are provided on both the first support plate and the third support plate. The guide pin is fixedly sleeved in the limiting through hole, for example by welding. The limiting through holes on the first support plate and the limiting through holes on the third support plate are aligned to ensure the vertical state of the guide pin.

[0012] Furthermore, the guide support also includes: a positioning pin seat, which is a ring structure and is sleeved on the outside of the guide pin. The inner ring surface of the positioning pin seat is fixedly connected to the guide pin, and the positioning pin seat and the first support plate are fixedly connected by screws.

[0013] Furthermore, a portion of the third support plate is connected to the top of the crossbeam of the base support, and a second reinforcing plate is connected to the bottom of another portion of the third support plate and the side of the crossbeam of the base support.

[0014] Furthermore, the top of the guide pin has a truncated cone structure.

[0015] Furthermore, the cross-section of the second reinforcing plate is an isosceles trapezoid, with one side fixedly connected to the bottom of the third support plate, and the other side parallel to the central axis of the guide pin and fixedly connected to the side of the crossbeam of the base support.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This utility model's guide assembly features multiple primary guide mechanisms positioned on the inner sides of the base and the battery box apex, and two secondary guide mechanisms positioned at a height below these primary guide mechanisms. Through a layered layout with gradient positioning from the outside in, the primary guide mechanisms at the apex initially guide the battery box into the base, achieving initial docking between the battery box and the base. This also disperses lateral loads caused by battery box swaying, facilitating precise alignment of the battery box and base by the secondary guide mechanisms after initial coarse positioning. This not only ensures uniform force distribution on the guide surface, reducing the risk of wear and deformation caused by directly using positioning pins, but also improves positioning accuracy and efficiency, ensuring rapid and precise docking of the battery box and base, thus enhancing the battery swapping efficiency of new energy battery-swapping heavy trucks.

[0032] Example A guide assembly for a new energy vehicle battery swapping heavy-duty truck-mounted battery swapping system is disclosed. The system comprises a rectangular base 2 and a cubic battery box 1 detachably mounted on the base 2. The guide assembly provides precise guidance during battery box 1 installation, enabling it to quickly and accurately align with the base 2. For example... Figure 1 and Figure 4 As shown, a fixed crossbeam 21 is configured at the bottom of the base 2, and the fixed crossbeam 21 is fixedly connected to the vehicle. The guide assembly includes: a first guide mechanism, a second guide mechanism, and a locking assembly, such as... Figure 3 , Figure 4 and Figure 5 As shown, the first guiding mechanism includes: multiple primary guide seats 5 and multiple first mating parts 3, such as... Figure 4 and Figure 5 As shown, multiple primary guide seats 5 are respectively arranged inside each vertex of the base 2 to initially guide the battery box 1 into the base 2, achieving initial docking between the battery box 1 and the base 2, and dispersing the lateral load caused by the swinging of the battery box 1; as Figure 3 As shown, multiple first mating parts 3 are respectively disposed on the inner side of each vertex position of the bottom frame 11 of the battery box 1, and the multiple first mating parts 3 correspond one-to-one with the positions of multiple first-level guide seats 5, and are mated with the first-level guide seats 5. like Figure 1 and Figure 3 As shown, the second guiding mechanism includes two secondary guide seats 6 and two second mating parts 4. The two secondary guide seats 6 are arranged on the base 2 along two diagonals of the base 2, and the two secondary guide seats 6 are located below the multiple primary guide seats 5, so that the first guiding mechanism contacts the bottom frame 11 of the battery box 1 first.

The two are positioned correspondingly, and a guide component is also provided between the female battery swapping connector 9 and the male battery swapping connector 10. It is worth noting that the battery swapping connector assembly is a conventional technology in existing battery swapping assemblies. It is only to illustrate that the purpose of the guide component in this embodiment is to achieve precise docking of the female battery swapping connector 9 and the male battery swapping connector 10 in the battery swapping connector assembly.

[0034] During docking, since the four primary guide seats 5 are positioned higher than the two secondary guide seats 6, when the battery box 1 and the base 2 dock, the primary guide seats 5 first enter for rough positioning. After the first mating part 3's engagement limiting surface fully enters the primary guide seat 5, the second mating part 4 and the two secondary guide seats 6 complete the insertion. Then, the pneumatic positioning pin 7 of the locking assembly extends and inserts into the positioning pin hole 71, thereby enabling the battery swapping connector female socket 9 and the battery swapping connector male socket 10 to achieve rapid and accurate alignment, ensuring the smooth operation of the battery swapping connector assembly.

[0035] like Figure 6 , Figure 7 and Figure 8 As shown, each primary guide seat 5 includes: a guide body 51, an inclined transition section 52, and a straight end panel 53.

The inclined transition section 52 includes two inclined plates, which are respectively connected to the top of the two plates of the angle plate structure and are inclined towards the inside of the base support 2. The straight end panel 53 is arranged parallel to the base support 2 and is connected between the tops of the two inclined plates. Each first mating part 3 includes a mating plate with a corner plate structure, and the two plates of the mating plate with the corner plate structure are fixedly connected to the two sides of the apex of the battery box 1, respectively.

[0036] A first reinforcing plate 56 is fixedly connected between the two plates of the guide body 51. The first reinforcing plate 56 is an angled structure cut from a rectangular tube profile. The outer wall of the first reinforcing plate 56 is fixedly connected to the inner wall of the guide body 51.

[0037] like Figure 6 and Figure 7 As shown, both plates of the guide body 51 are provided with square grooves. Guide pads 54 are fixedly connected to the top and bottom walls of the square grooves. Limiting spring plates 55 are also provided in the square grooves. The limiting spring plates 55 are arc-shaped spring plates, which include an arc-shaped part and a straight mounting part connected to both ends of the arc-shaped part. The mounting part at one end is fixedly connected to the guide pad 54 located at the top of the square groove by screws 57. The arc-shaped part protrudes from the square groove, and the mounting part at the other end abuts against the guide pad 54 located at the bottom of the square groove.

[0038] like Figure 3 As shown, the second mating part 4 is a fixing plate with a pin hole 41. The fixing plate is fixedly connected to the crossbeam of the bottom frame 11 of the battery box 1, as shown. Figure 9 , Figure 10 and Figure 11 As shown, each secondary guide seat 6 includes: a guide pin 61 and a guide support, the guide pin 61 being sized to match the pin hole 41; the guide support is mounted on the crossbeam of the base support 2, and the guide pin 61 is vertically connected to the guide support, as shown. Figure 9 As shown, the top of the guide pin 61 is a truncated cone structure.

[0039] like Figure 9 As shown, the guide support includes: a first support plate 62 and a third support plate 63 arranged in parallel, and a second support plate 64 connected between the first support plate 62 and the third support plate 63. The third support plate 63 is fixedly connected to the crossbeam of the base support 2. Limiting through holes 67 are provided on both the first support plate 62 and the third support plate 63. The guide pin 61 is fixedly sleeved in the limiting through hole 67, for example, by welding. The limiting through hole 67 on the first support plate 62 and the limiting through hole 67 on the third support plate 63 are aligned to ensure the vertical state of the guide pin 61.

[0040] like Figure 10 As shown, the guide support also includes a positioning pin seat 66, which is a ring structure and is sleeved on the outside of the guide pin 61. The inner ring surface of the positioning pin seat 66 is fixedly connected to the guide pin 61, and the positioning pin seat 66 and the first support plate 62 are fixedly connected by screws.

[0041] A portion of the third support plate 63 is connected to the top of the crossbeam of the base support 2, and a second reinforcing plate 65 is connected to the bottom of another portion of the third support plate 63 and the side of the crossbeam of the base support 2. The cross-section of the second reinforcing plate 65 is an isosceles trapezoid, one side of which is fixedly connected to the bottom of the third support plate 63, and the other side is parallel to the central axis of the guide pin 61 and fixedly connected to the side of the crossbeam of the base support 2.

[0042] The application method of the guide assembly in the battery swapping system in this embodiment is as follows: After the heavy truck carrying the battery swapping system assembly enters the battery swapping station, the station identifies the vehicle information and starts the battery swapping process. The battery swapping controller of the battery swapping system assembly issues a command to unlock the locking components on the battery box 1 and the base 2. After the pneumatic positioning pin is opened, the locking components are unlocked. After unlocking, the battery swapping controller reports that the battery swapping station has unlocked, and the station begins to lift the battery box 1 from the vehicle. During the lifting process, the male connector 10 of the battery box 1 and the female connector 9 of the battery swapping base 3 are first separated, cutting off the power circuit and communication between the battery box 1 and the base 2. Then, the secondary guide mechanism and the primary guide mechanism are separated in sequence until the battery box 1 and the base 2 are completely separated. The battery box 1 is then lifted from the vehicle and placed... Upon arrival at the battery swapping station, the fully charged battery box 1 is hoisted and moved onto the upper part of the base 2, then slowly lowered. It first enters the primary guide mechanism of the base 2, then the secondary guide mechanism, and then the guide component of the battery swapping connector assembly. Finally, the male connector 10 and the female connector 9 of the battery swapping connector are fully engaged, and the power circuit and communication circuit of the battery box 1 and the base 2 are connected. At the same time, the positioning detection switch 8 detects that the pneumatic positioning pin 7 is fully extended, indicating that the battery box 1 has been fully placed in place. The positioning detection switch 8 sends this signal to the battery swapping controller, which sends a command to the locking component to insert the pneumatic positioning pin 7 into the positioning pin hole 71, locking the battery box 1 and the base 2. After the battery box 1 is locked in place, the battery swapping controller sends a feedback to the vehicle, and the vehicle can leave the battery swapping station.
