DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0027] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications also change accordingly.

[0028] The present application provides a bottom shell and end cover connecting structure of an electric vehicle rotary knob switch.

[0029] In the present embodiment, with reference to Figures 1-6 The bottom shell and end cover connecting structure of the electric vehicle rotary knob switch comprises a bottom shell 1 and an end cover 2. The bottom shell extends upward with a connecting sleeve 3. The end cover is provided with a sleeve 4 which is sleeved with the connecting sleeve 3. The connecting structure further comprises a connecting cover 5, a pressing spring 6 and a connecting lock rod 7. The connecting cover is connected to the outer wall of the sleeve. The connecting sleeve is provided with a lock hole 8. The outer wall of the sleeve 4 and the connecting cover are both provided with a lock rod hole 9 for the connecting lock rod to pass through. The connecting lock rod is provided with a spring step 10. The pressing spring 6 is sleeved on the connecting lock rod. One end of the pressing spring abuts against the connecting cover, and the other end abuts against the spring step. The lock rod hole of the sleeve outer wall is provided with a limiting step 11 which can interfere with the spring step.

[0030] In the above technical solution, a connecting sleeve extends from the upper end of the bottom shell, a matching sleeve is provided on the end cap, and the connecting cover is mounted on the outside of the sleeve. The connecting locking rod passes through the locking rod holes provided on the outer wall of the sleeve and the connecting cover. The pressure applied by the pressure spring causes one end of the connecting locking rod to enter the locking hole of the bottom shell connecting sleeve, thereby achieving a quick locking of the bottom shell and the end cap. When disassembly is required, the user simply manually grasps the connecting locking rod, overcomes the resistance of the pressure spring, and pulls it out of the locking hole, thus easily completing the disassembly and assembly process.

[0031] The above technical solution enables quick installation and removal of the bottom shell and end cap without the need for additional tools. The elastic action of the pressure spring ensures that the connecting lock rod can be firmly pressed against the lock hole, improving the stability and reliability of the connection between the bottom shell and end cap.

[0032] The limiting step and the spring step interfere with each other, thereby preventing the connecting locking rod from being over-inserted and preventing the connecting locking rod from popping out of the locking rod hole on the outer wall of the sleeve.

[0033] Specifically, the outer dimensions of the spring step are larger than the locking rod hole on the connecting cover.

[0034] In this embodiment, the outer dimensions of the spring step are larger than the locking rod hole on the connecting cover, which can prevent the connecting locking rod from completely falling off from the locking rod hole in the connecting cover, thereby ensuring the durability and reliability of the connection.

[0035] Specifically, an unlocking step 12 is provided in the locking rod hole outside the limiting step.

[0036] like Figure 6 As shown, there are multiple unlocking steps, which are arranged on the inner walls of the three sides of the lock rod hole. A passage space for the spring step to pass through is formed between the multiple unlocking steps and the inner wall of the lock rod hole. The shape of the passage space is adapted to the shape of the spring step. When the spring step is aligned with the passage space, the spring step can pass through the passage space, while when it is not aligned, the spring step and the unlocking step interfere with each other. At this time, the spring step will counteract the unlocking step, making it impossible for the spring step to pass through the passage space. That is, when the bottom shell and the end cover are connected, the spring step is aligned with the passage space, and the connecting lock rod is connected to the lock hole under the elastic force of the pressure spring. When disassembling, the connecting lock rod is pulled out of the lock hole and rotated to a certain angle at the same time so that the spring step and the unlocking step counteract each other. At this time, the spring step and the unlocking step interfere with each other and cannot pass through the passage space. The connecting lock rod can be kept in an unlocked state, which facilitates the disassembly and assembly of the bottom shell and the end cover.

[0037] Specifically, a connecting boss 13 is integrally formed on the outer wall of the sleeve, and buckling steps 14 are provided on both sides of the connecting boss 13. The connecting cover is provided with a buckling notch 15 buckled with the buckling steps.

[0038] Through the design of the buckling step and the buckling notch, the quick installation and fixation of the connecting cover and the sleeve are realized, the assembly process is simplified, the installation stability of the connecting cover is improved, and the loosening caused by vibration and the like during use is prevented.

[0039] Specifically, the buckling step is provided with a lead-in slope 16 on one side of the connecting cover.

[0040] The design of the lead-in slope makes the connecting cover easier to slide into the buckling notch during installation, reduces the installation difficulty, ensures the smooth transition between the connecting cover and the sleeve, and improves the appearance and the user's experience.

[0041] Specifically, the two sides of the end of the connecting lock rod extending out of the connecting cover shell are provided with holding planes 17.

[0042] The design of the holding plane makes it easier for the user to hold the connecting lock rod during disassembly, pull and rotate the connecting lock rod, and improves the convenience and comfort of the operation.

[0043] Specifically, the two sides of the connecting sleeve are provided with alignment steps 18, and the inner wall of the sleeve is provided with alignment grooves 19 matched with the alignment steps.

[0044] The design of the alignment steps and the alignment grooves ensures the correct alignment of the bottom shell and the end cover during installation, avoids the misalignment phenomenon, improves the installation accuracy and consistency, and ensures the normal operation of the rotary knob switch.

[0045] Technical personnel should know: although the utility model has been described according to the above specific implementation mode, the utility model idea is not limited to this utility model, and any modification using the utility model idea will be included in the patent protection range.
