Description

Technical Field

[0001] This utility model relates to the field of battery monitoring equipment technology, and in particular to a wide-voltage power supply type full parameter LCD display instrument for batteries. Background Technology

[0002] LCD power meters are high-end products among digital power meters. Their display technology has evolved from analog pointer meters to digital LED digital displays to LCD displays. As a smart grid terminal device, this meter undertakes the functions of real-time power data acquisition and load management. Wide-voltage power supply type full-parameter LCD display meters can monitor battery voltage, current, SOC (state of charge), SOH (state of health), and single-cell voltage balance in real time, meeting the needs of visualization and refined management of battery status in multiple scenarios.

[0003] Battery full-parameter LCD display instruments are mainly used for real-time monitoring of battery parameters such as voltage, current, SOC (state of charge), SOH (state of health), and temperature. The data is presented intuitively through the LCD display, providing support for battery operation safety and lifespan management. However, traditional battery LCD display instruments have installation limitations. The fixed spacing of the mounting brackets, such as a preset single hole spacing, cannot be adapted to the battery compartments or installation areas of different devices. Additional drilling, welding of adapters, or replacement of dedicated instruments are required, resulting in low installation efficiency, high cost, and easy damage to the original structure of the equipment. To address these issues, we propose a wide-voltage power supply type battery full-parameter LCD display instrument. Utility Model Content

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4In this utility model, a wide-voltage battery-powered full-parameter LCD display instrument includes an LCD display instrument body 1. A bottom connecting seat 2 is fixedly connected to the bottom surface of the LCD display instrument body 1. Two guide rods 9 are fixedly connected to the inner wall of the bottom connecting seat 2. Two transmission square plates 10 are slidably connected to the outer surfaces of the two guide rods 9. A connecting arm 11 is fixedly connected to the outer surface of each transmission square plate 10. One end of each connecting arm 11 extends to the outside of the bottom connecting seat 2 and is fixedly connected to a mounting bracket 12 with an opening. A locking adjustment component 3 is installed on the bottom surface of the bottom connecting seat 2. Two square sliding frames 13 adapted to the connecting arms 11 are provided on the back of the bottom connecting seat 2, forming a sliding adjustment and guiding limit basic installation structure. The guide rods 9 restrict the linear sliding of the transmission square plates 10. The connecting arms 11 drive the mounting brackets 12 with openings to adjust the spacing synchronously. The square sliding frames 13 prevent the connecting arms 11 from tilting, fundamentally solving the core problems of fixed spacing and poor adaptation of traditional instruments.

[0023] The surface of the LCD instrument body 1 is provided with a wide-voltage power supply interface 4, and a heat sink 5 is installed on the back of the LCD instrument body 1. The wide-voltage power supply interface 4 facilitates external connection and avoids repeated disconnection and reconnection during installation, while the heat sink 5 increases the heat dissipation area and improves the heat dissipation effect. The locking adjustment component 3 includes a support frame 31 fixedly connected to the bottom surface of the bottom connecting seat 2, an adjustment block 33 fixedly connected to each transmission square plate 10 with the bottom end of the adjustment block 33 located inside the support frame 31, an adjustment screw 34 fixedly connected to each adjustment block 33, and a locking nut threadedly connected to each adjustment screw 34. 35. The surface of the support frame 31 is provided with a guide opening 36 that is adapted to the adjusting screw 34. The locking adjustment component 3 also includes a bottom rail 32 fixedly connected to the inner wall of the support frame 31. The bottom end of each adjusting block 33 is slidably connected to the bottom rail 32. The locking adjustment component 3 locks the adjusted spacing through the adjusting screw 34 and the locking nut 35. The support frame 31 provides stable support for the adjustment structure. The guide opening 36 restricts the adjusting screw 34 to move only along the spacing direction to avoid vibration causing the spacing to loosen. The bottom rail 32 restricts the adjusting block 33 to slide only along a straight line to avoid the adjusting block 33 from tilting during adjustment and improve adjustment efficiency.

[0024] Two side brackets 6 are fixedly connected to the back of the LCD instrument body 1 and the outer surface of the bottom mounting base 2. A guide rod 7 is fixedly connected between the two side brackets 6. Two connecting blocks 8 are slidably connected to the outer surface of the guide rod 7. The two connecting blocks 8 are respectively connected to the corresponding connecting arms 11. The side brackets 6 fix the guide rod 7, and the connecting blocks 8 connect the connecting arms 11 to the guide rod 7 to prevent the connecting arms 11 from warping up and down during adjustment. This ensures that the instrument is flat and vibration-free after installation. The bottom mounting base 2 and the locking adjustment component 3 have a common opening that matches the adjustment block 33. The opening between the bottom mounting base 2 and the locking adjustment component 3 provides space for the adjustment block 33 to move, preventing the adjustment block 33 from being blocked by the bottom mounting base 2 or the support frame 31 when moving. This ensures that the spacing adjustment range is maximized and can accommodate a wider range of installation position spacings.

[0025] The working principle of this utility model is as follows:

[0026] First, confirm that the guide rod 9 and the transmission square plate 10 slide smoothly, the locking nut 35 rotates flexibly, the wide voltage power supply interface 4 is undamaged, and the surface of the heat sink 5 is free of debris. Prepare installation tools such as wrenches and screwdrivers, and measure the installation spacing: use a tape measure to measure the bracket spacing of the battery equipment installation position, and determine the target spacing that the mounting bracket 12 with the opening needs to be adjusted.

[0027] Next, use a wrench to loosen the locking nut 35 of the locking adjustment component 3 counterclockwise, allowing the adjusting block 33 to move freely along the bottom rail 32. At this time, the transmission square plate 10 can also slide along the guide rod 9. Push the two transmission square plates 10 with both hands respectively, causing the connecting arm 11 to slide along the square slide frame 13 and the connecting block 8 along the guide rod 7, adjusting the spacing of the mounting bracket 12 until it matches the spacing of the mounting bracket. During the adjustment process, observe the mounting holes of the mounting bracket 12 to ensure they are aligned with the bracket holes. After confirming that the spacing of the mounting bracket 12 is aligned with the mounting holes, Tighten the locking nut 35 clockwise with a wrench to lock the adjusting block 33 onto the bottom rail 32, ensuring that the transmission square plate 10 is not loose. Then, use a screwdriver to pass the screw through the mounting hole of the mounting bracket 12 with the opening and connect and fix it to the installation position. Avoid touching the wide voltage power supply interface 4 during the installation process to prevent damage to the circuit. Finally, connect the battery power supply line to the wide voltage power supply interface 4, ensuring that the connection is secure. Turn on the battery power and observe whether the LCD instrument body 1 displays the battery parameters such as voltage and current normally. If the display is normal and there is no heat, the installation is complete.
