Description

Technical Field

[0001] This invention relates to the field of forklift battery technology, and more specifically, to a forklift battery with self-testing function and easy maintenance. Background Technology

[0002] Forklifts, as core handling tools in modern logistics and warehousing, rely heavily on the reliability of their power systems to determine operational efficiency and costs. Among these, electric forklifts powered by batteries are increasingly widely used due to their advantages such as zero emissions, low noise, and relatively simple maintenance. A forklift battery is an integrated power unit. Its main structure typically includes a housing and multiple (e.g., 4, 8, 16) standard lead-acid or lithium-ion batteries. These batteries are electrically connected in series within the housing to achieve the operating voltage required by the forklift motor (e.g., 24V, 48V, 72V). While this design meets basic power requirements, long-term use and maintenance have revealed the following significant drawbacks: First, there are significant inconveniences in fault diagnosis and maintenance. Because multiple batteries are tightly connected in series and encapsulated in a casing, their operating status is a "black box" for operators. When a fault occurs, it is often difficult to quickly pinpoint which battery is faulty. The forklift must be stopped to inspect the batteries, which is time-consuming. Furthermore, even if the faulty battery can be quickly identified, the difficulty in removing and installing batteries on a forklift means that replacing the faulty battery takes considerable time, resulting in prolonged forklift downtime and severely impacting material handling efficiency.

[0003] Secondly, the existing structure is insufficient to adapt to the harsh operating conditions of forklifts. Forklifts generate continuous vibrations and impacts during driving, lifting, and turning operations. These mechanical stresses are transmitted through the casing to the internal battery and its connection points. Over time, this can lead to the shedding of active material from the battery plates and loosening of external terminals, resulting in increased contact resistance, abnormal overheating, and even the risk of power failure. Simultaneously, the battery itself generates heat during charging and discharging. The densely packed structure within the enclosed casing hinders heat dissipation, easily causing localized overheating of the battery pack, accelerating electrolyte drying and plate sulfation, and severely shortening the overall battery life. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art and provide a forklift battery with self-testing function and convenient maintenance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a forklift battery, comprising a fixed mounting mechanism, a lifting and pressing mechanism, and a plurality of batteries arranged in a row; the batteries have positive terminals and negative terminals; the fixed mounting mechanism comprises a base plate, two side plates fixed to the base plate, a plurality of support seats, and a plurality of abutment limiting blocks, the support seats being connected to the base plate by a plurality of rubber pillars, the support seats having mounting grooves, temperature sensors being installed in the mounting grooves, the abutment limiting blocks having two guide slopes, and the abutment limiting blocks being connected to the base plate by a first spring; the lifting and pressing mechanism comprises a chamber, a plurality of heat-conducting units, a plurality of pressing units, a plurality of electrical connection units, and two lead-out units, the heat-conducting unit comprising an air outlet hood fixedly connected to the chamber, two heat-conducting plates hinged to the air outlet hood by elastic reset hinge components, and a second spring connecting the two heat-conducting plates; the pressing unit comprises two A vertical plate fixedly connected to the chamber section, two buffer blocks fixedly connected to the bottom ends of the two vertical plates respectively, a strip-shaped pressure plate, and two third springs connecting the chamber section and the strip-shaped pressure plate. The strip-shaped pressure plate and the two vertical plates are connected by connecting blocks. Multiple electrical connection units realize the series connection of multiple batteries. Each electrical connection unit includes a first conductive plate and two first conductive posts connected to the first conductive plate. Each first conductive plate spans two batteries and its two ends are connected to the two strip-shaped pressure plates respectively. The lead-out unit includes a second conductive plate and a second conductive post fixedly connected to the second conductive plate. The two second conductive plates are fixedly connected to the ends of the two outermost strip-shaped pressure plates respectively. The bottom of the chamber section has multiple first air outlets communicating with the air outlet hood and multiple second air outlets located between the two vertical plates. Multiple fan units are installed in the chamber section. The base plate and the chamber section are connected by multiple lifting mechanisms.

[0006] Furthermore, two second springs are connected between the two heat-conducting plates of the heat-conducting unit.

[0007] Furthermore, each battery is equipped with an independent voltage acquisition module.

[0008] This allows for independent monitoring of the voltage signal of each battery. Furthermore, when replacing a faulty battery, simply disconnect the voltage acquisition module from the faulty battery; when replacing a spare battery, connect the voltage acquisition module to the spare battery.

[0009] Furthermore, the forklift battery is equipped with a current acquisition module.

[0010] This allows for monitoring of the forklift battery current.

[0011] Furthermore, the number of multiple first air outlets and multiple air outlet covers are equal and correspond one-to-one, with each first air outlet connected to an air outlet cover.

[0012] Furthermore, the number of multiple second air outlets and multiple batteries are equal and correspond one-to-one, with one battery below each second air outlet.

[0013] Furthermore, in the two lead-out units, the second conductive post of one lead-out unit can be electrically connected to the positive terminal of one of the outermost batteries, and the second conductive post of the other lead-out unit can be electrically connected to the negative terminal of the other outermost battery.

[0014] Furthermore, multiple batteries are arranged in a row with equal spacing.

[0015] Furthermore, the chamber includes a top plate, a bottom plate, and a rectangular frame. Multiple first air outlets and multiple second air outlets are located on the bottom plate and are distributed alternately. Multiple fan units are installed on the rectangular frame.

[0016] Furthermore, the heat-conducting plate has multiple arc-shaped heat dissipation fins.

[0017] Furthermore, the multiple arc-shaped heat dissipation fins at the heat-conducting plate are divided into two groups, and the circles corresponding to the multiple arc-shaped heat dissipation fins in the same group are concentric circles.

[0018] Therefore, the arc-shaped heat dissipation fins can not only achieve better heat dissipation, but also serve as air guides. The heat dissipation airflow blowing down from above is dissipated to both sides by the arc-shaped heat dissipation fins, thus better removing heat.

[0019] Furthermore, the lifting mechanism is an electric telescopic rod or a hydraulic telescopic rod.

[0020] Furthermore, the lifting mechanism is an electric telescopic rod, and the electric lifting rod is connected to an independent power supply module.

[0021] Furthermore, the independent power supply module is powered by a lithium battery.

[0022] Therefore, the electric telescopic boom is independently powered and does not require power from the forklift battery. Thus, even if the forklift battery fails, the independent power supply module can still supply power to the electric telescopic boom.

[0023] Furthermore, the number of lifting mechanisms is two or four.

[0024] Furthermore, the abutment limiting block includes a cuboid portion and a guide portion connected to the cuboid portion, the guide portion having two guide ramps.

[0025] Furthermore, the top of the guide portion has a rounded chamfer.

[0026] As the heat-conducting plates descend, they will abut against the two guide slopes respectively. As a result, the bottom ends of the two heat-conducting plates will move away from each other under the action of the abutment limiting block. Finally, both heat-conducting plates will be abutted by the cuboid part of the abutment limiting block, thus the heat-conducting plates abut against the two batteries respectively.

[0027] Furthermore, the forklift battery can be in a non-maintenance state and a maintenance state. In the non-maintenance state, the lifting mechanism is at a first height, the buffer block abuts against the battery, each first conductive post is electrically connected to a positive or negative terminal, one second conductive post is electrically connected to the positive terminal of one of the outermost batteries, and the other second conductive post is electrically connected to the negative terminal of another outermost battery. Each heat-conducting plate abuts against the battery or a side plate, and each abutting limiting block abuts against two heat-conducting plates of a heat-conducting unit. The bottom distance between the two heat-conducting plates of the heat-conducting unit is a first distance. In the maintenance state, the lifting mechanism is at a second height, each first conductive post is not in contact with the positive or negative terminal, each second conductive post is not in contact with the positive or negative terminal, each heat-conducting plate is not in contact with the abutting limiting block, and the bottom distance between the two heat-conducting plates of the heat-conducting unit is a second distance. The first height is less than the second height, and the first distance is greater than the second distance.

[0028] Furthermore, in the non-maintenance state, two of the heat-conducting plates abut against the two side plates respectively, and the remaining heat-conducting plates abut against the battery.

[0029] Furthermore, in the non-maintenance state, all heat-conducting plates are in a vertical position.

[0030] Furthermore, the cross-section of the guide portion is an isosceles triangle with rounded corners at the top.

[0031] Furthermore, the storage battery is a lithium battery or a lead-acid battery, and the number of storage batteries is greater than or equal to four.

[0032] Furthermore, the cross-section of the air outlet hood is an inverted isosceles trapezoid.

[0033] Furthermore, each of the first conductive plates is connected at both ends to the ends of two strip-shaped pressure plates, and the two third springs at the strip-shaped pressure plates are located at both ends of the strip-shaped pressure plates.

[0034] Therefore, each positive or negative terminal has a corresponding third spring above it, and the downward pressure of the third spring allows the conductive post and the electrode post to better make contact and conduct electricity.

[0035] Furthermore, the support has a placement slot for placing the battery.

[0036] Furthermore, one end of the placement slot is open.

[0037] This makes it easier to remove the battery from the storage slot.

[0038] Furthermore, the end of the battery has a handle.

[0039] This makes it easier to remove the battery.

[0040] Furthermore, both the strip-shaped pressure plate and the vertical plate are made of engineering plastics.

[0041] Furthermore, the multiple rubber pillars connecting each support and the base plate are arranged in a rectangular array; each abutment limiting block is connected to two first springs, and the abutment limiting block is made of rubber material.

[0042] Furthermore, the buffer block is a rubber block.

[0043] This provides excellent buffering for the battery.

[0044] Furthermore, the strip-shaped pressure plate is connected to each vertical plate by two connecting blocks, which are rubber blocks, and the top and bottom ends of the connecting blocks have arc-shaped grooves.

[0045] Since the strip-shaped pressure plate and the vertical plate are connected by a connecting block, and the connecting block has a certain degree of flexibility, the position of the strip-shaped pressure plate relative to the vertical plate has room for change. Therefore, when the third spring is pressed down, it can press down the strip-shaped pressure plate well, so that the conductive post can better abut against the electrode post.

[0046] Furthermore, both the positive and negative terminals have insertion holes at their top ends, the insertion holes including cylindrical holes and frustoconical holes communicating with the cylindrical holes; both the first and second conductive terminals include cylindrical portions and frustoconical portions connected to the cylindrical portions.

[0047] This allows the frustoconical portions of the first and second conductive posts to better engage with the frustoconical holes of the socket, thus enabling better power transmission.

[0048] Furthermore, the end of the second conductive plate has a mounting through hole.

[0049] This allows for better installation of components such as electrical connection wires or conductive connectors.

[0050] Beneficial effects: 1. The forklift battery of this application can better monitor the working status of each battery. When a battery malfunctions, it can be detected in time, so as to carry out timely maintenance.

[0051] 2. The forklift battery of this application allows for faster disconnection of the electrical connections of each battery, and after disconnection, it enables the quick removal of the faulty battery and replacement with a spare battery.

[0052] 3. The forklift battery of this application integrates the electrical connection structure, the shock absorption structure and the heat dissipation structure, thereby achieving better shock absorption and heat dissipation for the forklift battery. Attached Figure Description

Each heat-conducting plate 4.2 All abut against the battery 1 or side plate 2.1. Each abutment limiting block 2.3 abuts against the two heat-conducting plates 4.2 of a heat-conducting unit.

[0058] Working Principle: During normal use, i.e., in the non-maintenance state, the top of the battery is pressed down by the buffer block, and the bottom support is supported by the rubber pillars, thus clamping the battery from the top and bottom for cushioning. Furthermore, the sides of the battery are abutted by heat-conducting plates, which are in contact with abutment limiting blocks. These limiting blocks are connected to the base plate via a first spring, further limiting the sides of the battery and providing a certain degree of cushioning. The battery is clamped and abutted at the top, bottom, and sides, ensuring stable installation. The airflow generated by the fan unit passes through the internal space of the chamber and exits through the first and second air outlets. The cooling airflow from the first outlet blows downwards onto the heat-conducting plates through the air shroud and is further dispersed to the sides by the arc-shaped cooling fins. The cooling airflow from the second outlet enters between two vertical plates, forming an air duct. The cooling airflow can then exit from both ends of the air duct, blowing heat through the positive terminal, negative terminal, first conductive post, and second conductive post, thereby dissipating heat at the electrical connection points.

[0059] When a battery malfunction is detected (an abnormal increase in the bottom temperature of the battery is detected by a temperature sensor), the operator can immediately stop the forklift. The lifting mechanism rises, causing the lifting and lowering mechanism to rise as well. Due to the action of the second spring, the two heat-conducting plates of the heat-conducting unit will move closer together, thus disengaging the heat-conducting plates from their contact with the battery. At the same time, the buffer block also disengages from its contact with the battery, allowing the operator to easily remove the faulty battery. A spare battery (the spare station has multiple batteries with different capacities; based on the remaining charge of the forklift battery, a spare battery with a similar remaining charge is selected and inserted into the support seat) is then lowered, restoring the series connection of the batteries and quickly restoring the forklift battery to usability.

[0060] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention without departing from the scope defined by the claims.
