Description

Technical Field

[0001] This utility model belongs to the technical field of winch control devices, specifically relating to a winch control device that uses Hall effect circuits for data acquisition. Background Technology

[0002] A winch typically uses a motor to drive a drum, which is electrically connected to an electrical control box. The control box contains a relay to control the drum's direction of rotation. Existing publication number CN205081459U discloses an overcurrent protection device, including an electrical control box, a protection circuit board, a constantan wire, a battery, and a motor. One end of the constantan wire is electrically connected to the battery, and the other end is electrically connected to the motor. The protection circuit board is electrically connected to the constantan wire to collect current changes. The electrical control box is connected to a relay, which engages or disengages to control the circuitry within the control box. The protection circuit board is also electrically connected to the relay and controls its engagement or disengagement based on current changes in the constantan wire. However, existing overcurrent protection devices using constantan wire have low accuracy in detecting current changes, making it difficult for the winch to disconnect near a set current level, resulting in low safety. Furthermore, the constantan wire is bulky, making assembly within the control box difficult. Therefore, a winch control device using Hall effect circuitry is needed to overcome these difficulties. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by designing a winch control device that uses Hall effect circuits to collect data. This invention detects the working current through a Hall effect sensing ring, which has high detection accuracy and is easy to install.

[0004] The objective of this invention is achieved through the following technical solution: a winch control device using Hall effect circuit acquisition, comprising a main housing, a drive relay electrically connected to the winch motor within the main housing, and a control module within the main housing, the control module comprising a main control circuit board, a microcontroller chip, and a small circuit board relay; the main control circuit board is electrically connected to both the microcontroller chip and the small circuit board relay, and the microcontroller chip and the small circuit board relay are electrically connected; a Hall effect sensing ring is mounted on the drive relay, and the Hall effect sensing ring is electrically connected to the microcontroller chip; a manual switch socket is also mounted on the main housing, and the manual switch socket is electrically connected to both the drive relay and the main control circuit board.

[0005] Preferably, the drive relay includes a positive terminal, a common terminal, and two output terminals arranged side by side, and a ground terminal is also provided at the bottom of the drive relay; a Hall effect sensing ring is fixedly installed on the outer layer of the positive terminal.

[0006] Preferably, the drive relay is electrically connected to the manual switch socket, the common terminal is electrically connected to the wire on the manual switch socket, and the grounding terminal is electrically connected to the wire on the manual switch socket; the drive relay is also provided with paired direction control terminals, which are respectively electrically connected to the wire on the manual switch socket.

[0007] Preferably, the drive relay is electrically connected to the main control circuit board, and the drive relay is also provided with an intermediate control terminal; the positive terminal is electrically connected to the wires on the main control circuit board, the ground terminal is electrically connected to the wires on the main control circuit board; the common terminal is electrically connected to the wires on the main control circuit board, and the intermediate control terminal is electrically connected to the wires on the main control circuit board.

[0008] Preferably, the common terminal and the grounding terminal are both electrically connected to the manual switch socket, and the common terminal and the grounding terminal are also electrically connected to the main control circuit board; the manual switch socket is connected in series with the small circuit board relay on the main control circuit board.

[0009] A small circuit board relay is connected in series with a manual switch socket, and the small circuit board relay is normally closed. A Hall effect sensor ring detects the real-time current of the winch during operation. A microcontroller chip converts the analog signal into a digital signal, and then the main control circuit board sends an electrical signal to the small circuit board relay based on the converted data. The microcontroller chip controls the on / off state of the small circuit board relay based on the current magnitude. Here, the maximum operating current can be preset by the microcontroller chip. When the actual operating current of the winch is greater than the preset maximum operating current, the small circuit board relay is in the open state, and the winch cannot work. When the winch current is less than the preset maximum operating current, the small circuit board relay is in the closed state. Since the manual switch socket is connected in series with the small circuit board relay, when the manual switch socket is turned on, the relay is energized, and the winch can work normally.

[0010] When the control module is in a faulty state, such as when the Hall effect sensor ring or components within the main control circuit board are damaged, the small circuit board relay will remain in a closed state. However, by sending a working command to the drive relay via a manual switch socket, the winch can still operate normally, offering better versatility. By setting intermediate control terminals and direction control terminals, the current direction of the motor within the winch can be switched, thereby changing the motor's direction of rotation, further enhancing versatility.

[0011] Preferably, the Hall effect sensor ring is provided with a first lead-out terminal, and the main control circuit board is provided with a second lead-out terminal, wherein the first lead-out terminal and the second lead-out terminal are pluggable and electrically connected.

[0012] By setting the first lead-out terminal and the second lead-out terminal, it is convenient to electrically connect the Hall effect sensor ring to the main control circuit board.

[0013] Preferably, the main housing includes a base and an outer shell, on which a manual switch socket is mounted; a control module and a drive relay are mounted on the base; a Hall effect sensor ring is mounted on the drive relay; when the base and the outer shell are assembled into the main housing, a gap is left between the Hall effect sensor ring and the inner wall of the main housing; the outer contour of the Hall effect sensor ring is adapted to the outer contour of the terminals on the drive relay.

[0014] The base and housing facilitate the installation of drive relays and control modules.

[0015] Preferably, the control module also includes a detachable plastic housing, in which the main control circuit board, the microcontroller chip, and the small circuit board relay are all installed.

[0016] The plastic casing facilitates the assembly of the main control circuit board, microcontroller chip, and small circuit board relays. Additionally, a waterproof sealing strip is installed on the upper edge of the casing, providing waterproof functionality for the control module.

[0017] Compared with the prior art, this utility model has the following advantages: 1. The maximum operating current can be set within any range through the microcontroller chip, which has good versatility; 2. The maximum operating current is pre-selected by the microcontroller, and then the main control circuit board can send an electrical signal to the small circuit board relay, which is convenient for controlling the on and off of the small circuit board relay and the overcurrent protection accuracy is higher; 3. The Hall sensing ring has a compact structure and is easy to install between the main housing and the drive relay. Attached Figure Description

The main control circuit board 31 is electrically connected to both the microcontroller chip 32 and the small circuit board relay 33, and the microcontroller chip 32 and the small circuit board relay 33 are electrically connected. A Hall effect sensing ring 4 is mounted on the drive relay 2, and the Hall effect sensing ring 4 is electrically connected to the microcontroller chip 32. A manual switch socket 5 is also mounted on the main housing 1, and the manual switch socket 5 is electrically connected to both the drive relay 2 and the main control circuit board 31.

[0026] The drive relay 2 includes a positive terminal 6, a common terminal 7, and two output terminals 8 arranged side by side. A grounding terminal 9 is also provided at the bottom of the drive relay 2. A Hall effect sensor ring 4 is fixedly installed on the outer layer of the positive terminal 6. The drive relay 2 is electrically connected to a manual switch socket 5. The common terminal 7 is electrically connected to the wires on the manual switch socket 5, and the grounding terminal 9 is electrically connected to the wires on the manual switch socket 5. The drive relay 2 also has paired direction control terminals 10, which are electrically connected to the wires on the manual switch socket 5. The drive relay 2 is electrically connected to a main control circuit board 31. The drive relay 2 also has an intermediate control terminal 11. The positive terminal 6 is electrically connected to the wires on the main control circuit board 31, and the grounding terminal 9 is electrically connected to the wires on the main control circuit board 31. The common terminal 7 is electrically connected to the wires on the main control circuit board 31, and the intermediate control terminal 11 is electrically connected to the wires on the main control circuit board 31. The common terminal 7 and the ground terminal 9 are both electrically connected to the manual switch socket 5, and the common terminal 7 and the ground terminal 9 are also electrically connected to the main control circuit board 31; the manual switch socket 5 is connected in series with the small circuit board relay 33 on the main control circuit board 31.

[0027] The Hall effect sensor ring 4 is provided with a first lead-out terminal 12, and the main control circuit board 31 is provided with a second lead-out terminal 13. The first lead-out terminal 12 and the second lead-out terminal 13 are pluggable and electrically connected. The main housing 1 includes a base 101 and an outer shell 102. A manual switch socket 5 is installed on the outer shell 102. A control module 3 and a drive relay 2 are installed on the base 101. The Hall effect sensor ring 4 is installed on the drive relay 2. When the base 101 and the outer shell 102 are assembled into the main housing 1, a gap is left between the Hall effect sensor ring 4 and the inner wall of the main housing 1. The outer contour of the Hall effect sensor ring 4 is adapted to the outer contour of the terminal on the drive relay 2. The control module 3 also includes a detachable plastic shell 34. The main control circuit board 31, the microcontroller chip 32, and the small circuit board relay 33 are all installed in the plastic shell 34.

[0028] The specific operation process of this embodiment is as follows: the small circuit board relay 33 is connected in series with the manual switch socket 5, and the small circuit board relay 33 is in a normally closed state; the Hall sensor ring 4 can detect the real-time current during the operation of the winch, and convert the analog quantity into a digital quantity through the microcontroller chip 32. Then, the main control circuit board 31 sends an electrical signal to the small circuit board relay 33 through the converted data of the microcontroller chip 32; the microcontroller chip 32 controls the on / off state of the small circuit board relay 33 according to the current magnitude. Here, the maximum operating current can be preset by the microcontroller chip 32; when the actual operating current of the winch is greater than the preset maximum operating current, the small circuit board relay 33 is in an open state, and the winch cannot work. When the winch current is less than the preset maximum operating current, the small circuit board relay 33 is in a closed state; since the manual switch socket 5 is connected in series with the small circuit board relay 33, when the manual switch socket 5 is turned on, the drive relay 2 will be in a energized state, and the winch can work normally. The manual switch socket 5 works in conjunction with the external handle switch, which is an existing standard part and is not shown in the drawings of the instruction manual.

[0029] When control module 3 is in a faulty state, such as when the Hall sensor ring 4 or components within the main control circuit board 31 are damaged, the small circuit board relay 33 will remain in a closed state. In this case, a working command is sent to the drive relay 2 via the manual switch socket 5, allowing the winch to still operate normally, thus improving its versatility. By setting the intermediate control terminal 11 and the direction control terminal 10, the current direction of the motor within the winch can be switched, thereby changing the motor's direction of rotation, further enhancing its versatility.
