Detailed Description
The invention is described in detail below with reference to the attached drawing figures:
embodiment one:
referring to fig. 1 to 4, the present invention provides a switch 101 for charging an automobile. The switch 101 for charging an automobile includes a housing 10, a magnetic switch assembly 20 provided in the housing 10, a latch 40 provided on the housing 10 and movable, and a magnet 50 provided on the latch 40.
Referring to fig. 5, the housing 10 is used to support other components of the vehicle charging switch 101. The material of the housing 10 is selected according to the need. In this embodiment, the housing 10 is a plastic member for facilitating electrical insulation. The particular shape and configuration of the housing 10 is selected according to the particular application requirements. In this embodiment, the housing 10 has a cavity wall 11. The cavity wall 11 encloses a receiving cavity 13. The accommodating cavity 13 is used for accommodating the magnetic switch assembly 20. Further, in order to facilitate the electrical connection, the accommodating cavity 13 is a through cavity penetrating along the extending direction of the housing 10. That is, the housing 10 is formed with openings 15a, 15b at both front and rear ends, respectively. The opening 15a at the front end is for receiving a connection terminal 70 described below. The opening 15b at the rear end is adapted to receive a connector 85 described below. In order to facilitate the holding operation by a human hand, the two ends of the cavity wall 11 and the accommodating cavity 13 extend respectively and are disposed at an angle to each other.
The housing 10 may be of unitary, one-piece construction. In the present embodiment, the housing 10 includes a bottom case 10a and a top cover 10b in order to facilitate the installation of the corresponding components. The top of the bottom case 10a has an opening. The top cover 10b is covered on the bottom shell 10a, and encloses the cavity wall 11 and the accommodating cavity 13. After the bottom case 10a and the top cover 10b are assembled, a stable integrated part is formed by ultrasonic welding.
The outer surface of the housing 10 is provided with recesses 17. The recess 17 is disposed opposite the magnet 50 and is movable to be accommodated in the recess 17 when the magnet 50 rotates following the latch 40. The recess 17 prevents the magnet 50 from being deviated in the process of reciprocating away from and approaching the housing 10, thereby maintaining magnetic induction sensitivity and accuracy.
The bottom wall of the recess 17 is provided with a protruding boss (not shown in the figures). The boss may be received in the retaining portion 46 of the latch 40 and may abut the received retaining portion 46.
In order to facilitate the maintenance of the protective cover 35 and the assembly, the bottom case 10a is provided with positioning posts 121, 122 in the present embodiment. The upper cover 10b is also provided with positioning posts 151, 152, 153, 154, respectively. The positioning posts 121, 122 and 151, 152, 153, 154 may be received in the positioning holes 351, 352, 353, 354, 355, 356 of the corresponding shield cover 35.
To further secure the switch 101 for car charging in one piece and to enhance the retention of other components, the housing 10 further includes a lumen wall 112. The lumen wall 112 encloses a lumen 115. The lumen 115 communicates with the receiving cavity 13. In this embodiment, the lumen 115 is disposed at the rear end of the housing 10. The lumen wall 112 extends along the circumference of the connector 85 described below and holds the connector 85. The end 114 of the lumen wall 112 is adapted for axial interference fit with a second lock 90 described below to enhance positive retention of the connector 85. In the present embodiment, the end 114 is a front end of the lumen wall 112 in the assembly direction of the connector 85.
In order to facilitate the reciprocal movement of the magnet 50 relative to the magnetic sensor 25 by the latch 40, a rotary shaft 19 is provided on the outer surface of the housing 10. The rotation shaft 19 is used for supporting the locking piece 40 and enabling the locking piece 40 to rotate. In order to firmly support the rotation shaft 19, two holding portions (not shown) are provided on the housing 10. Each of the holding portions is provided with a mounting hole (not shown) for receiving the rotation shaft 18. It is conceivable that the housing 10 and the catch 40 can also be connected in a swivel manner, for example by means of a pivot, a hinge or the like.
With continued reference to fig. 2 and 4, the magnetic switch assembly 20, which may also be referred to as a magnetically controlled switch assembly, is a device that controls switching of a corresponding circuit (or electronic component) according to a magnetic field signal. The magnetic switch assembly 20 is accommodated in the accommodating cavity 13 of the housing 10. The magnetic switch assembly 20 is arranged to be turned on or off in dependence of a detected change in the magnetic field strength. It is contemplated that the magnetic field strength reaching the magnetic switch assembly 20 changes during the approaching and moving away of the magnet 50. The specific type, specification and switching principle of the magnetic switch assembly 20 are only required to be able to realize corresponding on or off according to the corresponding change of the magnetic field intensity. For example, when the magnet 50 approaches the magnetic switch assembly 20 to a certain preset position, the magnetic field strength detected by the magnetic switch assembly 20 is increased to a conduction threshold value, so as to conduct a conduction action; when the magnet 50 moves away from the magnetic switch assembly 20 to another preset position, the magnetic field strength detected by the magnetic switch assembly 20 decreases to an off threshold, thereby performing an off action.
To facilitate the switching operation and to enhance the accuracy of the reaction, the magnetic switch assembly 20 includes a magnetic sensor 25. The magnetic sensor 25 may also be referred to as a magnetic sensor, or a magnetic sensing element. The magnetic sensor 25 is accommodated in the accommodation chamber 13 of the housing 10. The magnetic sensor 25 is used to sense the magnetic field strength. In this embodiment, the magnetic sensor 25 is used to sense the magnetic field strength provided by the magnet 50. The specific specification and type of the magnetic sensor 25 may be one that can satisfy the strength of the induced magnetic field. The magnetic sensor 25 may be a magneto-resistive sensor, or a position sensor. In this embodiment, the magnetic sensor 25 is a hall sensor, or a hall switch. Further, the magnetic sensor 25 is provided on a circuit board 28 described below. The magnetic sensor 25 is electrically connected to the circuit board 28 and transmits a corresponding sensed signal to the circuit board 28.
To facilitate processing of the signals of the magnetic sensor 25 and to facilitate electrically connecting the connection terminals 70 and the connection members 85 described below, the magnetic switch assembly 20 further includes a circuit board 28. The circuit board 28, also called a circuit board, is abbreviated as PCB (Printed Circuit Board, i.e. printed circuit board). The circuit board 28 is used to make electrical connections and to transmit electrical current, electrical signals, etc. The circuit board 28 is disposed on the housing 10. Specifically, the circuit board 28 is accommodated in the accommodation chamber 13 of the housing 10. The circuit board 28 may be held on the housing 10 in any manner. In the present embodiment, the circuit board 28 is disposed on a terminal support base 75 described below, and is held in a corresponding position with respect to the housing 10 by the terminal support base 75 being accommodated in the accommodation chamber 12. The specific shape, size and type of the circuit board 28 is selected as desired. In the present embodiment, the circuit board 28 has a substantially long plate shape.
It will be appreciated that the magnetic switch assembly 20 may also include electronics, such as processing modules, disposed on the circuit board 28 and in communication with the circuit board 28 automotive charging connector, as desired for a particular application. The processing module may be used for processing the corresponding signals. The processing module may employ a central processing unit to perform its functions.
Referring to fig. 1 to 4, and fig. 6, the latch 40 is disposed on the housing 10. At least a portion of the latch 40 is proximally and distally positionable relative to the housing 10 to actuate the magnet 50 proximally and distally positioned relative to the magnetic sensor 25. The latch 40 may be specifically shaped and configured to support the magnet 50 and drive the magnet 50 away from and toward the magnetic sensor 25. In this embodiment, the latch 40 is generally rod-shaped. To facilitate the movement of the magnet 50 toward and away from the magnetic sensor 25, the latch 40 is rotatably disposed relative to the housing 10. More specifically, in the present embodiment, the latch member 40 is sleeved on the rotation shaft 19 and is rotatably disposed with respect to the housing 10. To further facilitate manual operation, the middle portion of the latch 40 is sleeved on the rotation shaft 19, so that both ends of the latch 40 are rotatably disposed with respect to the housing 10. Specifically, the middle part of the latch 40 is provided with a mounting hole 41. The locking member 40 is sleeved on the rotating shaft 19 through the mounting hole 41.
