Technical Field

[0001] The utility model belongs to the technical field of power batteries, and in particular relates to a cold chain logistics vehicle-mounted battery circuit board testing device. Background Art

[0002] BMS battery system is commonly known as battery nanny or battery steward. It is mainly used to intelligently manage and maintain each battery unit, prevent overcharging and over-discharging of the battery, extend the battery life, and monitor the battery status. The BMS battery management system unit includes a BMS battery management system, a control module, a display module, a wireless communication module, electrical equipment, a battery pack for powering electrical equipment, and a collection module for collecting battery information of the battery pack. The BMS circuit board needs to be tested for its performance during production. The existing BMS circuit board test often needs to be completed manually. The BMS circuit board is fixed and then tested manually. For example, a BMS circuit board test device disclosed in a Chinese patent, application number: 2 02122981644.1, including: a cabinet; a fixing seat, a fixing groove is formed on the fixing seat; a pressing mechanism, the pressing mechanism is arranged above the fixing seat, and is used to press the BMS circuit board into the fixing groove; a trigger switch, the trigger switch is arranged at the bottom of the fixing groove, and is used to be triggered and generate a trigger signal when the BMS circuit board is pressed into the fixing groove; a control module, the trigger switch and the pressing mechanism are both connected to the control module signal; a test interface, the test interface is arranged in the fixing groove, and is used to be electrically connected to the BMS circuit board; a current acquisition module, the current acquisition module is electrically connected to the test interface, and is connected to the control module signal; a voltage acquisition module, the voltage acquisition module is electrically connected to the test interface, and is connected to the control module signal. The disadvantage of this structure is that only one circuit board can be tested at a time. Each time, a BMS circuit board is placed on the fixing seat first, and then the pressing device is started for testing. After the test is completed, the pressing device is raised again, the BMS circuit board is taken out, and a BMS circuit board is put back in, and the process is repeated in sequence. This structure has a relatively low working efficiency and needs to be improved. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0016] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0017] like Figure 1 and Figure 2 As shown, a cold chain logistics vehicle-mounted battery circuit board testing device includes a base 1, a first support base 2, a second support base 3, a vertical plate 4, a transverse moving cylinder 5, a vertical moving cylinder 6, a transverse guide rail 7, a vertical guide rail 8, a transverse moving plate 9, an L-shaped probe base 10 and a probe 11; the first support base and the second support base are respectively fixed on both sides of the base, wherein the first support base and the second support base are two workstations respectively, and the upper parts of the first support base and the second support base are provided with BMS limit grooves 13, and the BMS limit grooves are used to place the BMS circuit board to be tested.

[0018] The vertical plate is vertically fixed on the base. In order to reinforce the vertical plate, a reinforcing plate 12 is fixed between the vertical plate and the base.

[0019] The transverse moving cylinder is fixed on the side of the vertical plate, the piston rod of the transverse moving cylinder is fixedly connected to the back side of the transverse moving plate, the back side of the transverse moving plate is slidably connected to the transverse guide rail through a slider, the transverse guide rail is transversely fixed on the vertical plate, and the transverse cylinder drives the transverse moving plate to move left and right on the vertical plate, so that the probe is switched above the first support seat and the second support seat.

[0020] In order to enable the probe to move up and down and test the BMS circuit board, the vertical guide rail is vertically fixed to the front side of the horizontal moving plate, the L-shaped probe seat is slidably matched with the vertical guide rail through a slider, the vertical moving cylinder is fixed to the lower part of the horizontal moving plate, the piston rod of the vertical moving cylinder is connected to the bottom of the L-shaped probe seat, and the probe is installed on the upper part of the L-shaped probe seat. The vertical moving cylinder drives the L-shaped probe seat to move up and down, thereby driving the probe to move up and down.

[0021] Furthermore, there are two transverse guide rails, which are distributed on both sides of the transverse moving cylinder, and the two transverse guide rails are respectively fixed to the sides of the vertical plate through the guide rail seats 14. The guide rail seats support the two transverse guide rails at a certain distance so that the transverse moving cylinder can be accommodated between the transverse moving plate and the vertical plate.

[0022] In order to prevent the L-shaped probe support from moving down too far, resulting in excessive pressure on the probe and damaging the circuit board, the device is provided with a limit block 15 on the vertical plate for limiting the movement of the L-shaped probe support. The limit block can support the bottom of the L-shaped probe support to prevent it from moving further downward.

[0023] In order to facilitate the replacement of probes of different models, the probes are mounted on a probe connecting plate 16 , and the probe connecting plate is fixed to the through hole on the top of the L-shaped probe seat by bolts.

[0024] The circuit principles used by the probes in this device are all existing technologies, and the circuit principles in the background technology can also be used. Different BMS circuit boards measure different points, so the circuit principles are also different. Technicians can design them by themselves without any technical difficulties.

[0025] When in use, first place a BMS circuit board on the first support seat, then start the vertical moving cylinder, the vertical moving cylinder drives the probe downward, the probe touches the contacts on the BMS circuit board for testing, during the test, place the second BMS circuit board on the second support seat, at this time, the test of the first BMS circuit board is completed, the vertical moving cylinder drives the probe upward, and the horizontal moving cylinder drives the probe to move above the second BMS circuit board. After it is in place, the vertical moving cylinder drives the probe downward to test the second BMS circuit board. At the same time, remove the BMS circuit board on the first support seat, and then place the third BMS circuit board, and repeat this process.

[0026] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
