Description

Technical Field

[0001] This utility model relates to the field of electric tractor technology, specifically to assembly tooling, battery frame assembly, and vehicle. Background Technology

[0002] In recent years, with the continuous development of new energy technologies, battery-swapping heavy-duty trucks have gained widespread market favor in the heavy-duty truck sector due to their advantages such as speed, convenience, and high energy efficiency. The battery packs of battery-swapping heavy-duty trucks are typically mounted on the chassis behind the cab via battery frames. Specific designs allow for quick disassembly and installation of the battery packs, significantly reducing charging time and improving vehicle operating efficiency.

[0003] Currently, the side-mounted battery frames of existing electric heavy trucks are mainly connected to the side of the frame via bolts and other connectors. Since the battery frame needs to house the battery pack and pipeline harnesses, the internal structure is quite complex. In order to reliably connect the battery frame to the frame, the battery pack and pipeline harnesses cannot be installed before the battery frame and frame are assembled. This means that the battery pack and other related components need to be installed sequentially during the overall vehicle assembly, resulting in a long assembly time for the entire vehicle. Utility Model Content

[0004] In view of this, the present invention provides an assembly tooling, a battery frame assembly, and a vehicle to solve the problem of long assembly time for existing electric heavy trucks.

[0005] In a first aspect, the present invention provides an assembly fixture for fixing connectors on a battery frame, comprising: a first clamping frame having at least one first clamping part; a second clamping frame having at least one second clamping part, the second clamping part being disposed in a one-to-one correspondence with the first clamping part, the second clamping frame being movably disposed on the first clamping frame along the longitudinal direction, and the second clamping part and the first clamping part forming a clamping space for accommodating the connector.

[0006] Beneficial effects: The second clamping frame is movably mounted on the first clamping frame, making the overall assembly fixture simple and reliable. After the connector is inserted into the battery frame, the connector can be clamped and fixed by the cooperation of the first and second clamping frames. In the subsequent assembly process, the connector can be directly inserted into the connection hole on the vehicle frame as the battery frame moves, thus enabling the subsequent connector fixing steps to be carried out directly without reserving space for connector installation. This allows battery packs and other related components to be pre-installed in the battery frame, greatly shortening the assembly process on the assembly line and effectively solving the problem of long assembly time for existing electric heavy trucks.

[0007] In one alternative embodiment, the first clamping frame is provided with a guide hole extending longitudinally, and the second clamping frame is movably inserted into the guide hole.

[0008] Beneficial effects: The guide hole can effectively guide and constrain the movement of the second clamping frame. At the same time, the second clamping frame passing through the guide hole can also prevent it from separating from the first clamping frame during operation.

[0009] In one alternative embodiment, the first clamping frame includes a first bearing portion and a guide portion. The first bearing portion extends longitudinally, and the guide portion has a guide groove with an opening facing the first bearing portion. The guide portion is disposed on the side wall of the first bearing portion, and the two together form a guide hole.

[0010] Beneficial effects: The forming method of the guide hole is simple and reliable. This type of first clamping frame realizes the assembly method of first placing the second clamping frame and then connecting the guide part with the first bearing part, which can effectively avoid the limitation of the guide hole on the shape of the second clamping frame.

[0011] In one alternative embodiment, there are multiple first clamping portions that are spaced apart along the longitudinal direction on the first support portion, and the second clamping frame includes a second support portion that extends along the longitudinal direction. There are multiple second clamping portions that are spaced apart along the longitudinal direction on the second support portion, and the second support portion is movably inserted into the guide hole.

[0012] Beneficial effects: This type of first and second clamping frame can simultaneously clamp and fix multiple connectors at multiple positions, which can effectively improve positioning consistency and positioning reliability.

[0013] In one alternative embodiment, a guide portion is provided between adjacent first clamping portions.

[0014] Beneficial effects: This arrangement of the guide parts can distribute the force at each guide part, which not only improves the reliability of the guide, but also makes the movement of the second clamping frame more stable and reliable.

[0015] In one alternative embodiment, the first clamping part is provided with a limiting groove, and the opening of the limiting groove is disposed facing the adjacent second clamping part.

[0016] Beneficial effect: The limiting groove can further enhance the constraint ability of the first clamping part on the connecting part.

[0017] In one alternative embodiment, the first clamping portion has multiple upper limit slots, which are arranged at vertical intervals.

[0018] Beneficial effects: A first clamping part can reliably limit the position of multiple vertical connectors at the same time. Compared with positioning multiple connectors by contacting them with a plane, the limiting method in this embodiment is more stable and reliable.

[0019] Secondly, this utility model also provides a battery frame assembly, which includes: a frame having an internal installation space and a connecting beam, the connecting beam having a connecting hole; a connector passing through the connecting hole, the frame being connected to the vehicle frame through the connector; and the aforementioned assembly fixture clamping and cooperating with the connector.

[0020] In one alternative embodiment, a positioning frame connected to the connecting beam is further included. The positioning frame has a through hole for a connector, which is a bolt. The shape of the through hole matches the shape of the bolt head, and the through hole is adapted to engage with the head of the connector to restrict bolt rotation.

[0021] Beneficial effects: By setting up a positioning frame, the stability of the connector can be improved during the movement of the frame. In addition, the positioning frame can also improve the structural strength of the connecting beam. At the same time, after the connector is installed on the frame, the positioning frame can restrict the rotation of the connector. When the operator puts the nut on the connector, the connector can be reliably connected to the frame by rotating the nut.

[0022] Thirdly, the present invention also provides a vehicle comprising: a frame; the aforementioned battery frame assembly, which is connected laterally to one side of the frame; and a battery pack disposed in the mounting space of the battery frame assembly. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The following is combined with Figures 1 to 12 The following describes embodiments of the present invention.

[0028] In related technologies, when installing the battery frame, the connection holes of the battery frame must first be aligned with the connection holes of the vehicle frame before bolts can be passed through the two connection holes to connect them. In order for this process to proceed smoothly, the battery pack and related pipeline circuits cannot be installed in advance before the battery frame is assembled. The battery pack and pipeline circuits must be assembled sequentially during the assembly and assembly of the battery frame assembly on the vehicle assembly line. Pre-assembly is not possible, which seriously affects the production line rhythm.

[0029] According to an embodiment of the present invention, in one aspect, an assembly fixture is provided for fixing a connector 5 on a battery frame. The assembly fixture includes: a first clamping frame 1 and a second clamping frame 2. The first clamping frame 1 has at least one first clamping part 101, and the second clamping frame 2 has at least one second clamping part 201. The second clamping part 201 is arranged in a one-to-one correspondence with the first clamping part 101. The second clamping frame 2 is movably disposed on the first clamping frame 1 along the longitudinal direction. The second clamping part 201 and the first clamping part 101 form a clamping space 3 for accommodating the connector 5.

[0030] The assembly fixture of this embodiment has a second clamping frame 2 movably mounted on the first clamping frame 1. The overall structure of the assembly fixture is simple and reliable. After the connector 5 is inserted into the battery frame, the connector 5 can be clamped and fixed by the cooperation of the first clamping frame 1 and the second clamping frame 2. In the subsequent assembly process, the connector 5 can be directly inserted into the connection hole on the frame 7 as the battery frame moves, so that the subsequent fixing steps of the connector 5 can be carried out directly without reserving space for the installation of the connector 5. This allows the battery pack and other related components to be pre-installed in the battery frame, which greatly shortens the assembly process on the assembly line and effectively solves the problem of long assembly time of existing electric heavy trucks.

[0031] It should be noted that, in this embodiment, "horizontal" refers to... Figure 1 The horizontal direction indicated by the middle arrow refers to the vertical direction. Figure 1 The "vertical" direction indicated by the middle arrow refers to... Figure 1 The "vertical" direction indicated by the middle arrow.

[0032] The specific number of the first clamping part 101 and the second clamping part 201 is not limited. There can be one or more, as long as the number of the two matches. The selection can be made according to the position of the connector 5 to be clamped.

[0033] In addition, such as Figures 7 to 12 As shown, connector 5 is a bolt. The operation of the assembly fixture can realize quick bolt clamping and positioning and fixture removal. Through structural adaptation, it can also be used for the rapid assembly of frame structures other than battery frames, with diverse application scenarios.

[0034] In one possible implementation, such as Figure 1 As shown, the first clamping frame 1 is provided with a guide hole 102 extending longitudinally, and the second clamping frame 2 is movably inserted into the guide hole 102. The guide hole 102 can effectively guide and constrain the movement of the second clamping frame 2. At the same time, the second clamping frame 2 inserted into the guide hole 102 can also prevent separation from the first clamping frame 1 during operation.

[0035] Specifically, the form of the guide hole 102 is not limited; it can be a round hole, a rectangular hole, etc., as long as the shape matches the insertion part of the second clamping frame 2.

[0036] In one possible implementation, such as Figure 1 As shown, the first clamping frame 1 includes a first supporting part 103 and a guide part 104. The first supporting part 103 extends longitudinally, and the guide part 104 has a guide groove with an opening facing the first supporting part 103. The guide part 104 is disposed on the side wall of the first supporting part 103, and the two together form a guide hole 102. The forming method of the guide hole 102 is simple and reliable. This type of first clamping frame 1 realizes the assembly method of first placing the second clamping frame 2 and then connecting the guide part 104 with the first supporting part 103, which can effectively avoid the limitation of the guide hole 102 on the shape of the second clamping frame 2.

[0037] The number of guide sections 104 is not limited; there can be one or multiple spaced sections, as long as they can form guide holes 102 for the second clamping frame 2 to pass through.

[0038] In one possible implementation, there are multiple first clamping parts 101 arranged longitudinally at intervals on the first support part 103, and the second clamping frame 2 includes a second support part 202 extending longitudinally. There are multiple second clamping parts 201 arranged longitudinally at intervals on the second support part 202, and the second support part 202 is movably inserted into the guide hole 102. This type of first clamping frame 1 and second clamping frame 2 can simultaneously clamp and fix multiple connectors 5 at multiple positions, which can effectively improve positioning consistency and positioning reliability.

[0039] The spacing between adjacent first clamping parts 101 and adjacent second clamping frames 2 is not limited and can be selected according to the specific arrangement of the connectors 5.

[0040] In one possible implementation, such as Figure 1 As shown, each of the adjacent first clamping parts 101 is provided with a guide part 104. This arrangement of the guide parts 104 can distribute the force at each guide part 104, which not only improves the reliability of the guide, but also makes the movement of the second clamping frame 2 more stable and reliable.

[0041] In one possible implementation, the first clamping part 101 is provided with a limiting groove 1011, the opening of the limiting groove 1011 is provided facing the adjacent second clamping part 201, the limiting groove 1011 can further enhance the constraint ability of the first clamping part 101 on the connector 5, when the connector 5 enters the corresponding limiting groove 1011, it cannot move in any radial direction, thereby improving the clamping stability and reliability of the assembly tooling.

[0042] In one possible implementation, the first clamping part 101 has multiple upper limit grooves 1011, which are arranged at intervals along the vertical direction. One first clamping part 101 can reliably limit multiple vertical connectors 5 at the same time. Compared with positioning multiple connectors 5 by abutting with a plane, the limiting method of this embodiment is more stable and reliable.

[0043] The shape of the limiting groove 1011 is not limited and can be a V-shaped groove, U-shaped groove, arc groove or rectangular groove, etc., which can be selected according to the specific shape and size of the connector 5.

[0044] According to an embodiment of the present invention, in another aspect, a battery frame assembly is provided, which includes: a frame 4, a connector 5, and the aforementioned assembly fixture. The frame 4 has an installation space inside and a connecting beam 401, and the connecting beam 401 is provided with a connecting hole 4011. The connector 5 passes through the connecting hole 4011, and the frame 4 is connected to the vehicle frame 7 through the connector 5. The assembly fixture clamps and cooperates with the connector 5.

[0045] Among them, the types of connectors 5 include, but are not limited to, bolts, connecting pins, etc.

[0046] In one possible implementation, such as Figures 3 to 6 As shown, the battery frame assembly also includes a positioning frame 6 connected to the connecting beam 401. The positioning frame 6 has a through hole 601 for the connector 5 to pass through. The connector 5 is a bolt. The shape of the through hole 601 matches the shape of the bolt head. The through hole 601 is suitable for engaging with the head of the connector 5 to restrict the rotation of the bolt. By setting the positioning frame 6, the stability of the connector 5 during the movement of the frame 4 can be improved. In addition, the positioning frame 6 can also improve the structural strength of the connecting beam 401. At the same time, after the connector 5 is passed on the frame 7, the positioning frame 6 can restrict the rotation of the connector 5. When the operator puts the nut on the connector 5, the connector 5 can be reliably connected to the frame 7 by rotating the nut.

[0047] In this embodiment, due to the presence of the positioning bracket 6, no additional tools are needed to clamp the bolt head when assembling the nut, and therefore no operating space needs to be reserved for clamping the bolt head, which can effectively improve the space utilization rate of the electrical components inside the battery frame assembly.

[0048] When the operator installs and tightens the nut, the positioning bracket 6 can not only prevent the bolt from rotating, but also prevent the bolt from moving away from the nut.

[0049] Specifically, such as Figure 4 and Figure 6 As shown, the positioning frame 6 is a plate-shaped structure. The positioning frame 6 extends vertically and is detachably connected to the connecting beam 401 through fasteners 602. The positioning frame 6 is provided with fixing holes 603 for fasteners 602 to pass through. The fasteners 602 can be screws, bolts, connecting pins, etc. The number of fasteners 602 and fixing holes 603 is not limited. There can be one or multiple holes spaced apart, as long as the positioning frame 6 can be stably and reliably connected to the connecting beam 401.

[0050] Preferably, such as Figure 4 and Figure 6 As shown, the perforation 601 is a hexagonal hole, and the head of the connector 5 is also hexagonal. It should be noted that the perforation 601 and the head of the connector 5 are not limited to hexagons, and the number of sides can be changed according to requirements, such as becoming pentagonal.

[0051] Furthermore, such as Figure 6 As shown, a gasket is also provided between the positioning frame 6 and the connecting beam 401. The gasket is fitted onto the fastener 602 and can press the fastener 602 tightly.

[0052] Additionally, it should be noted that, in order to more clearly demonstrate the assembly process of the battery frame assembly and the vehicle frame 7, this embodiment... Figures 7 to 12 The battery pack, wiring harnesses and pipes related to high and low voltage and thermal management components installed inside the frame 4 are not shown. In reality, the battery frame assembly has already been assembled with the relevant components and can be directly connected to the vehicle frame 7.

[0053] In this embodiment, both the assembly fixture and the positioning frame 6 can be made of standard thickness plates, which can be processed by cutting, drilling, bending, and assembly. The manufacturing process is simple and the cost is low.

[0054] According to an embodiment of the present invention, in another aspect, a vehicle is provided, comprising: a frame 7, the aforementioned battery frame assembly, and a battery pack for the frame 7, wherein the battery frame assembly is connected laterally to one side of the frame 7, and the battery pack is disposed in the mounting space of the battery frame assembly.

[0055] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
