Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to battery components and tethered UAVs. Background Technology
[0002] When a drone takes off, it needs the upward lift of the air. This is achieved by the rotation of the propellers in a horizontal plane. The upward lift is generated by the interaction between the curved surfaces of the propellers and the air. To keep the propellers rotating, batteries are usually used to provide the driving force.
[0003] Currently, the batteries used in drones have certain requirements for ambient temperature. When the temperature is too low, the batteries are prone to failure. Specific manifestations include, but are not limited to, reduced battery voltage, poor discharge performance, and short lifespan. This makes it difficult for such drones to be used in low-temperature areas at high latitudes and high altitudes, limiting their applicability and reducing their competitiveness.

[0029] This embodiment discloses a battery assembly and a tethered drone including the battery assembly. Specifically, the tethered drone also includes a fuselage, and the battery assembly is mounted on the fuselage. Figure 1 and Figure 2 As shown, the battery assembly includes a battery body 1, a heating element and a heating power supply. The heating element is detachably wrapped around the outside of the battery body 1, and the heating power supply is used to supply power to the heating element so that the heating element is maintained within a set temperature range. The battery body 1 and the heating element are respectively mounted on the body.
[0030] The heating element of the battery assembly can maintain a set temperature range and exchange heat with the battery body 1 from the outside, ensuring that the battery body 1 is in a suitable operating temperature range, avoiding the battery from failing to operate normally due to low temperature, extending the battery's lifespan, improving the power supply capacity of the battery body 1, expanding the market for the battery assembly in low-temperature areas such as high latitudes and high altitudes, and enhancing product competitiveness.
[0031] This battery assembly is suitable for drones, electric vehicles, portable electronic devices, and especially for external heating of onboard batteries in tethered drones. Specifically, this battery assembly is suitable for tethered drones, where the battery body 1 and the heating element can take off with the fuselage, the heating power supply remains on the takeoff and landing platform, and the wire connecting the heating power supply and the heating element also serves as the tethering line. A stable power supply to the heating element is provided through the tethering line, eliminating concerns about insufficient power supply causing the heating element to malfunction. There are no limitations on the energy consumption of the heating element, making it widely applicable.
[0032] The specific structure of the heating element is not limited, as long as it can heat the external surface of the battery body 1. In one structure, the heating element includes at least two parallel heating tubes 2, all of which are evenly distributed on the outer side of the battery body 1. The heating tubes 2 can convert electrical energy into heat energy, using this heat energy to raise the temperature of the battery body 1, preventing the battery body 1 from being affected by low-temperature environments and thus ensuring that the battery body 1 is in good working condition. The even distribution of all heating tubes 2 ensures a uniform surface temperature distribution of the battery body 1, avoiding a shortened lifespan due to excessive temperature differences across the battery body 1.
[0033] The specific structure and model of the heating element 2 are not limited; any device that can generate heat using electrical energy in the prior art is acceptable. In this embodiment, the heating element 2 has multiple settings, with different settings corresponding to different temperatures and power, so that the battery body 1 can reach the set temperature value as quickly as possible.
[0034] The specific method for achieving the wrapping of the heating tube 2 around the battery body 1 is not limited. In this embodiment, the heating part also includes a heat-conducting element 3, and at least some of the heating tubes 2 are inserted into the heat-conducting element 3. When the sheet-like heat-conducting element 3 wraps around the outside of the battery body 1, all the heating tubes 2 are surrounded on the outside of the battery body 1. The heat on the heating tubes 2 is transferred to the battery body 1 through the heat-conducting element 3. This improves the overall structural rigidity without affecting the heat exchange between the heating tubes 2 and the battery body 1, and prevents the heating tubes 2 from falling off the battery body 1.
[0035] The specific material used to prepare the heat-conducting component 3 is not limited, as long as it has good thermal conductivity, can be bent freely, and can fit tightly against the outer periphery of the battery body 1. In this embodiment, a lightweight and flexible material is used to prepare the heat-conducting component 3 to avoid affecting the maneuverability and payload capacity of the drone, resulting in a better user experience.
[0036] To ensure that the heat-conducting component 3 does not easily detach from the battery body 1, in this embodiment, the heat-conducting component 3 is provided with snap fasteners 31 or Velcro on opposite sides. In use, the sheet-like heat-conducting component 3 is bent sequentially to cover the battery body 1; the snap fasteners 31 or Velcro on both sides of the heat-conducting component 3 are aligned and fastened, and the heat-conducting component 3 is securely wrapped around the outside of the battery body 1. The snap fasteners 31 or Velcro make the heat-conducting component 3 easy to install and remove, facilitating maintenance and replacement, saving time and effort.
[0037] To accommodate the use of battery bodies 1 of different models and sizes, the heat-conducting component 3 is also equipped with a position adjustment band 32. The buckles 31 and / or Velcro can be repositioned along the position adjustment band 32 to adjust the cross-sectional area of the object that the heat-conducting component 3 can wrap around. Specifically, when the heat-conducting component 3 is unfolded flat, the closer the corresponding buckles 31 or Velcro on the left and right sides are, the smaller the cross-sectional area of the object that the heat-conducting component 3 can wrap around, which is suitable for external heating of smaller battery bodies 1; the farther apart the corresponding buckles 31 or Velcro on the left and right sides are, the larger the cross-sectional area of the object that the heat-conducting component 3 can wrap around, which is suitable for external heating of larger battery bodies 1.
[0038] The specific structure of the heat-conducting component 3 is not limited, as long as it can fix the heating tube 2 and does not affect the heat exchange between the heating tube 2 and the battery body 1. In this embodiment, the heat-conducting component 3 includes a heat-conducting layer and a heat-insulating layer. The heat-conducting layer is attached to the outer side of the battery body 1, and the heat-insulating layer is wrapped around the outside of the heat-conducting layer.
[0039] The heat-conducting layer is made of a material with good thermal conductivity, which can be, but is not limited to, a fabric with a large number of metal wires threaded through it, in order to achieve efficient heat conduction; the insulation layer is made of a material with good insulation performance and easy to bend, which can be, but is not limited to, soft rubber, heat-insulating sponge, etc., to avoid heat exchange between the heating pipe 2 and the surrounding environment and waste of heat energy.
[0040] In another structure, the heating element is a resistance wire, a mature product that generates more heat energy under the same power consumption and is more convenient to use. To improve the uniformity of heating, the resistance wire is arranged in an S-shape, covering the outer side of the battery body 1 as large an area as possible and evenly as possible.
[0041] Based on the above structure, the battery assembly also includes a control device and a temperature sensor located near the battery body 1. The temperature sensor is used to measure the temperature value of the battery body 1 in real time, and the control device is connected to the temperature sensor and the heating power supply respectively.
[0042] The control device can receive the temperature measurement results of the battery body 1 from the temperature sensor, and can start and stop the heating power supply and adjust the setting of the heating tube 2. Specifically, when the temperature of the battery body 1 is lower than the set value, the control device turns on the heating power supply and adjusts the heating tube 2 to the high setting, so that the heating tube 2 heats up quickly and raises the temperature of the battery body 1 as soon as possible; when the temperature of the battery body 1 is higher than the set value, the control device turns off the heating power supply and the heating tube 2 stops heating; when the temperature of the battery body 1 is equal to the set value, both the heating power supply and the heating tube 2 maintain their current state.
[0043] In this embodiment, the control device can be a centralized or distributed controller. For example, the controller can be a single microcontroller or a combination of multiple distributed microcontrollers. The microcontroller can run a control program to control the heating power supply, heating tube 2 and temperature sensor to achieve their functions.
[0044] The temperature sensor sends the measured temperature value of the battery body 1 to the control device. The control device controls the start and stop of the heating power supply and the output power of the heating tube 2 according to the change of the temperature value, so as to realize the automatic control of the battery assembly.
[0045] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
