Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle auxiliary equipment, in particular to a switching device used for extinguishing fire of lithium batteries of electric vehicles. Background Art

[0002] For electric bicycles, whether they are two-wheeled or three-wheeled vehicles, fire-fighting equipment is not designed or installed during production and subsequent use. Moreover, due to space limitations, two-wheeled and three-wheeled vehicles cannot be equipped with fire extinguishers like cars, so there are safety hazards when in use or charging.

[0003] In order to reduce the losses caused by electric vehicle fires, it is necessary to add fire-fighting equipment to existing two-wheeled or three-wheeled electric vehicles, that is, to add fire extinguishers to existing vehicles, install sprinkler pipes connected to the fire extinguishers in the battery compartment, and sensors for monitoring various data in the battery compartment. At this time, it is necessary to open a through hole in the vehicle shell for the passage of the pipeline. However, a simple opening will cause wear between the pipeline and the edge of the through hole during driving, resulting in damage to the pipeline. Moreover, after the hole is opened, the pipeline can only be passed through, and the pipeline cannot be constrained, resulting in the scattered distribution of the pipeline in the battery compartment, which is not easy to carry out subsequent maintenance and equipment replacement. Utility Model Content

[0004] In order to solve the above problems, an embodiment of the present utility model provides a lithium battery fire extinguishing adapter device for two-wheeled or three-wheeled electric vehicles, which can protect and position pipelines.

[0006] As a further improvement of the above technical solution:

[0007] The adapter includes a positioning sleeve threadedly connected to the threaded pipe, and one end of the positioning sleeve is provided with a pressing plate located outside the limiting plate.

[0008] The end of the threaded tube is provided with a clamping boss corresponding to the position of the limiting plate.

[0009] The limiting plate is provided with a wiring groove located outside the protective tube, and the wiring groove is provided with a positioner for fixing the wiring harness.

[0021] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] like Figure 1-6 As shown, the lithium battery fire extinguishing adapter device of this embodiment includes a positioning part 1 installed on the vehicle shell and a mounting part 2 for installing pipelines. The positioning part 1 includes a positioning ring plate 3 connected to the vehicle shell by adhesion or screws, and the positioning ring plate 3 is provided with a threaded tube 4. The mounting part 2 includes a protective tube 5 passed through the threaded tube 4, and a limiting plate 6 abutting the end of the threaded tube 4 is provided on the outer wall of the protective tube 5. An adapter 7 connected to the threaded tube 4 is provided on the outside of the protective tube 5. The design of the protective tube 5 can place the pipeline and the wiring harness in the protective tube 5 to avoid damage to the pipeline and the wiring harness due to friction. The mounting part 2 is connected to the vehicle shell through the positioning part 1, and is designed to be split from the protective tube 5. The structure is simple and convenient to install and disassemble.

[0023] The adapter 7 includes a positioning sleeve 8 threadedly connected to the threaded tube 4. One end of the positioning sleeve 8 is provided with a clamping plate 9 located outside the limit plate 6. The clamping plate 9 presses the limit plate 6 to prevent the protective tube 5 from shaking during use.

[0024] The end of the threaded tube 4 is provided with a snap-fitting boss 10 corresponding to the position of the limit plate 6. The design of the snap-fitting boss 10 can keep it flush with the upper end surface of the threaded tube 4 after the limit plate 6 is placed, and at the same time pre-limit the limit plate 6 to facilitate the installation of the adapter 7.

[0025] The limiting plate 6 is provided with a wiring groove 11 located outside the protective tube 5, and the wiring groove 11 is provided with a locator 12 for fixing the wiring harness. The protective tube 5 is used to pass through the fire extinguishing agent pipeline and the original output circuit of the tram. The wiring groove 11 is designed to insert the wiring harness connected to the sensor in the battery compartment.

[0026] The wiring slots 11 are arc-shaped and there are multiple of them distributed along the circumference of the protective tube 5. A partition 13 is provided between two adjacent wiring slots 11. The design of the multiple wiring slots 11 can be selected according to different installation positions of the sensor to avoid the phenomenon of line entanglement.

[0027] The positioner 12 includes a base 14 that is slidably connected to the wiring slot 11. Clamping plates 15 are provided at both ends of the base 14 and are located on both sides of the limit plate 6. Each wiring slot 11 is provided with multiple positioners 12. A avoidance groove 16 is provided on the side walls at both ends of each positioner 12. The avoidance groove 16 is semicircular. The splicing of two avoidance grooves 16 can form a circular ring for clamping the wiring harness. The position of the wiring harness can be changed by moving the positioner 12.
