It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0034] Reference Figures 1-4 As shown, this application embodiment provides a detachable base assembly, which includes a boss 1 and a male seat 2. The boss 1 is used to connect to an electrical component, and the male seat 2 is adapted to a female seat on the vehicle body. The end face of the male seat 2 away from the locking block 26 is provided with a recessed groove 21 for the boss 1 to be inserted into, which is suitable for connecting the male seat 2 and the boss 1 by screws 3 when the boss 1 is inserted into the recessed groove 21.

[0035] Specifically, the boss 1 can be fixed to the housing of the electrical component with glue or integrally formed with the housing.

[0036] Reference Figures 2-3As shown, furthermore, to facilitate the connection of the boss 1 and the male seat 2 via the screw 3, a nut 4 that mates with the screw 3 is provided on the boss 1, and a connecting hole 22 for the screw 3 to pass through is provided on the base. When the boss 1 is embedded in the recessed groove 21, the nut 4 corresponds to the connecting hole 22. Since the axial thickness of the male seat 2 is small, the connecting hole 22 is located on the end face of the male seat 2 near the locking block 26 and its axis is perpendicular to the end face. The two ends of the connecting hole 22 are connected, so the screw 3 can pass through the connecting hole 22 along the axial direction of the male seat 2 and connect with the nut 4 on the boss 1. In addition, to avoid the screw 3 protruding from the end face of the male seat 2 and affecting the engagement with the female seat, a countersunk hole 23 is provided on the end face of the male seat 2 near the locking block 26 at the connecting hole 22. The countersunk hole 23 is adapted to the screw 3 so that the head of the screw 3 is embedded in the countersunk hole 23. In this embodiment, the screw 3 is illustrated with a conical head, and the corresponding countersunk hole 23 is a conical countersunk hole 23.

[0037] Reference Figure 3 As shown, further, the boss 1 is configured to include a mounting surface 11. The side of the boss 1 opposite to the mounting surface 11 is connected to the electrical component housing. When the boss 1 is embedded in the recessed groove 21, the mounting surface 11 is located in the recessed groove 21 and perpendicular to the axis of the connecting hole 22. The nut 4 is provided on the mounting surface 11 and embedded in the boss 1. Specifically, in this embodiment, the mounting surface 11 is formed on the side of the boss 1 away from the electrical component housing. When the boss 1 is embedded in the recessed groove 21, the mounting surface 11 faces the bottom surface of the recessed groove 21 and the nut 4 is coaxial with the connecting hole 22, so that the screw 3 passes through the connecting hole 22 and is connected to the nut 4, thereby fixing the male seat 2 and the boss 1 together.

[0038] During manufacturing, nut 4 is connected to boss 1 using insert injection molding. This one-time molding process avoids subsequent assembly errors and reduces post-processing costs. Insert injection molding also ensures nut 4 has greater tensile and torsional strength, guaranteeing reliability and lifespan during use. Nut 4 maintains its function and performance even after repeated disassembly. Meanwhile, male seat 2 is made of plastic injection molding, using high-strength materials to ensure the high pull-out force required when electrical components are installed on the female seat. Alternatively, metal die casting or CNC machining can be used to meet different customized needs.

[0039] Reference Figures 2-3 As shown, to improve the connection reliability between the boss 1 and the male seat 2, multiple nuts 4 and connecting holes 22 are provided in equal numbers. When the boss 1 is embedded in the recessed groove 21, the multiple nuts 4 correspond one-to-one with the multiple connecting holes 22, that is, when the boss 1 is embedded in the recessed groove 21, the multiple connecting holes 22 and the multiple nuts 4 are coaxial and correspond one-to-one. This allows the boss 1 and the male seat 2 to be connected by multiple screws 3, thereby improving the connection reliability between the male seat 2 and the electrical components. In this embodiment, the multiple nuts 4 are all located at the edge of the mounting surface 11 and are distributed circumferentially along the mounting surface 11.

[0040] ReferenceFigures 2-3 As shown, the recessed groove 21 is cylindrical, perpendicular to the end face of the male seat 2. The boss 1 is cylindrical and adapted to the recessed groove 21. One end face of the boss 1 forms a mounting surface 11, while the other end face connects to the housing of the electrical component. This allows the boss 1 to be inserted axially into the recessed groove 21 when it is coaxial with it. To achieve the positioning and assembly of the boss 1 and the male seat 2, a positioning groove 12 extending axially is provided on the side wall of the boss 1, and a positioning protrusion 24 adapted to the positioning groove 12 is provided on the inner wall of the recessed groove 21. The boss 1 is configured to be embedded axially into the recessed groove 21 when it is coaxial with the recessed groove 21 and the positioning protrusion 24 is aligned with the positioning groove 12. When the positioning protrusion 24 is not aligned with the positioning groove 12, the boss 1 is restricted to be embedded in the recessed groove 21. This configuration achieves the positioning and assembly of the boss 1 and the male seat 2. The cross-sectional shapes of the recessed groove 21 and the boss 1 can be designed as needed, and can be circular or other irregular shapes. In this embodiment, the sidewall of the boss 1 protrudes outward at the location of the nut 4 to strengthen the structural strength of the location of the nut 4.

[0041] Reference Figure 3 As shown, further, the boss 1 has multiple through holes 14 at the center of the mounting surface 11. When the boss 1 is connected to the housing of the electrical component, the through holes 14 are connected to the inside of the housing of the electrical component so that the buzzer installed in the housing of the electrical component can emit sound. In addition, two inclined grooves 13 are provided on opposite sides of the mounting surface 11, and sound outlets 25 are provided on opposite side walls of the recessed groove 21, which are connected to the recessed groove 21 and the outside. When the boss 1 is embedded in the recessed groove 21, the two inclined grooves 13 and the two sound outlets 25 correspond to each other so that the alarm sound emitted by the buzzer in the electrical component can be emitted through the through holes 14 and the sound outlets 25.

[0042] Reference Figure 5 As shown, this embodiment also provides a code reader, which includes a code reader body 5 and a detachable base assembly as described above. Specifically, in this embodiment, the boss 1 is integrally formed on the outer shell of the code reader body 5, and the through hole 14 directly connects the inside and outside of the outer shell of the code reader body 5. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
