Description

Technical Field

[0001] The utility model belongs to the technical field of new energy vehicles, and relates to a new energy vehicle and a placement and positioning device thereof, in particular to a placement and positioning device for large equipment of a new energy vehicle with large equipment components. Background Art

[0002] At present, new energy vehicles such as hydrogen fuel and battery-swap tractor vehicles have been widely used. The dimensions of the hydrogen storage system and battery-swap system currently used are larger and heavier than those of traditional energy components. Taking the hydrogen fuel 6×4 traction chassis hydrogen storage system as an example, the dimensions of 8×210 liter hydrogen storage cabinets are (length×width×height) 1.2m×2.5m×2.7m, and the weight is about 1800kg. During the assembly process of the hydrogen storage system and the frame, the crane needs to be manually operated for multiple adjustments to align with the installation holes. Since standard parts are prone to misalignment during assembly and there is a gap between the mounting bracket and the bottom bracket, the crane needs to be operated again for adjustment, resulting in repeated operations that extend the operation time. At the same time, there are safety hazards.

[0003] In summary, the assembly components of the above-mentioned large components of new energy vehicles need to be further optimized to improve positioning accuracy and assembly efficiency. Summary of the invention

[0004] In order to solve the problem that misaligned holes are prone to occur during the assembly of large equipment components of the above-mentioned new energy vehicles, resulting in long operation time and potential safety hazards, the utility model proposes a large equipment component drop-in positioning device that can accurately position and improve assembly efficiency, and a new energy vehicle with the positioning device.

[0005] The utility model is realized by the following technical solutions:

[0006] The above-mentioned large equipment component installation and positioning device for new energy vehicles includes a pin shaft and a connecting bracket; the pin shaft is installed on the base bracket of the large equipment component, extends outward perpendicular to the installation direction, is symmetrically distributed on both sides of the base bracket, and is set at least at one place in the front and back of one side; the connecting bracket matches the pin shaft, installs the frame of the new energy vehicle, and the upper part protrudes out of the frame and is provided with a limiting guide groove; the limiting guide groove matches the pin shaft for positioning.

[0007] The large equipment component installation and positioning device for new energy vehicles, wherein: the limiting guide groove is a V-shaped groove formed by being recessed downward from the top of the connecting bracket.

[0008] The large equipment component installation and positioning device for new energy vehicles, wherein: the circumferential outer wall of the pin shaft is fixedly connected with a protective sleeve.

[0009] The large equipment component drop-in positioning device for new energy vehicles, wherein: the limiting guide groove is provided with a connecting pad, and the outer wall of the connecting bracket is provided with a corresponding hole in the middle of the upper end of the assembly hole.

[0010] The large equipment component placement and positioning device for new energy vehicles, wherein: the inner wall of the corresponding hole is fixedly connected to a limiting cylinder, and the inner wall of the circumference of the limiting cylinder is slidably connected to a button. The inner cavity of the button is fixedly connected to a first spring, and the first two ends of the first spring are fixedly connected to a first limiting ball. The outer wall of the button is fixedly connected to a connecting frame, and the end of the connecting frame is fixedly connected to a pushing frame. The limiting cylinder is penetrated to form a limiting hole, the inner wall of the limiting hole is fixedly connected to the limiting frame, and the inner cavity of the limiting hole is slidably connected to a second limiting ball.

[0011] The above-mentioned new energy vehicle includes large equipment components and a frame, and has any of the above-mentioned drop-down positioning devices.

[0012] The new energy vehicle, wherein: the large equipment component is provided with a base bracket, and the base bracket is provided with a bracket mounting hole; the frame is provided with a connecting piece and a frame mounting hole matching the connecting bracket mounting hole of the drop-in positioning device; the connecting piece is provided with a frame mounting hole matching the bracket mounting hole; the pin shaft of the drop-in positioning device is arranged on one side of the bracket mounting hole; the fastener of the drop-in positioning device passes through the mounting hole of the connecting bracket and the frame mounting hole and is locked and fixed by a nut. Beneficial Effects

[0013] The utility model provides a pin shaft, a large equipment component, a vehicle frame, and a vehicle frame connecting plate. After the vehicle frame connecting plate is fixedly installed on the vehicle frame by installing standard parts, the large equipment component is dropped. When the large equipment component is dropped on the vehicle frame, the pin shaft is clamped on the vehicle frame connecting plate, so that the large equipment component is accurately positioned on the vehicle frame, which is convenient for subsequent installation and does not require multiple crane adjustments, thus saving time and effort.

[0014] Based on the first beneficial effect, when installing the frame connecting plate on the frame, it is necessary to manually fit the frame connecting plate to the appropriate position of the frame, and then press the button first. The button enters the limiting cylinder, so that the first limiting ball contacts the inner wall of the limiting cylinder and squeezes the first spring. The button drives the pushing frame to move inside the limiting cylinder through the connecting frame, and the pushing frame contacts the second limiting ball and pushes it out of the limiting hole. When the button stops being pressed, the first spring rebounds and drives the first limiting ball to fully contact the inner wall of the limiting cylinder to limit the button. The button limitation limits the pushing frame, and the pushing frame limitation limits the second limiting ball, so that the second limiting ball contacts the inner wall of the frame, so that the frame connecting plate is fixedly connected to the frame, which is convenient for preliminary limiting of the frame connecting plate and prevents the position of the frame connecting plate from being offset when the standard parts are fixedly installed.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The connecting bracket 2 matches the pin shaft 1 and is assembled and fixed on the frame of the new energy vehicle. A mounting hole 21 is provided at the bottom, and a limiting guide groove 22 is provided at the top protruding from the frame. In this embodiment, there are four mounting holes 21, which are equidistantly arranged at the bottom of the connecting bracket 2 and match the frame. The limiting guide groove 22 is a V-shaped groove formed by being recessed downward from the top of the connecting bracket 2. The position of the V-shaped groove is arranged to avoid other components and should be close to the mounting hole of the base bracket of the large equipment component. It matches and cooperates with the pin shaft 1, and positioning is achieved as the pin shaft 1 falls into the limiting guide groove 22.

[0028] The fastener 3 passes through the assembly hole 21 of the connecting bracket 2 and is assembled and fixed to the frame; in this embodiment, the fastener 3 is assembled to the frame using bolts and nuts.
