Description

Technical Field

[0001] This application relates to the field of drone battery temperature control sleeves, and more particularly to a drone battery temperature control sleeve. Background Technology

[0002] Drones are powered by batteries, which drive the propellers to rotate, thus enabling them to fly.

[0003] However, in cold weather, the chemical reaction inside the battery slows down due to the cold environment, resulting in a significant decrease in battery capacity and a drastically shortened battery life.

[0004] During use, the battery needs to be installed in the drone's battery compartment before the drone can be started. However, when the battery is placed in the drone from a cold environment, its temperature will be close to the ambient temperature. The low temperature will increase the battery's internal resistance, making it unable to provide high current output. This will result in insufficient power output from the drone, making it difficult to take off and causing sluggish flight. In severe cases, it may lead to loss of flight control.

[0005] Secondly, when the battery is at a low temperature, the electromagnetic load performance decreases. If a high power output is forced, it can easily damage the battery cells, leading to bulging, short circuits, or fires, which seriously threaten the safety of the pilot. Utility Model Content

[0006] In view of this, it is necessary to provide a temperature control sleeve for drone batteries to solve the above problems.

[0014] In at least one embodiment of this application, the heating element is arranged around the heat storage channel.

[0015] In at least one embodiment of this application, there are two heating sleeves, and the accommodating cavity is formed between the two heating sleeves. Each heating sleeve is provided with at least one heating element and at least one heat-conducting element.

[0016] In at least one embodiment of this application, the first heat-conducting fin and the second heat-conducting fin form an inclined heat-conducting portion, and a bonding heat-conducting portion is provided between two adjacent inclined heat-conducting portions, the bonding heat-conducting portion being bonded to the inner wall of the heating cavity on the side near the other heating sleeve.

[0017] In at least one embodiment of this application, the protective sleeve body further includes an installation cavity;

[0026] The elastic sleeve is provided with an adhesive part, and the shielding part is bonded to the adhesive part to cover the gap at the connection between the bottom shielding sleeve and the elastic sleeve.

[0027] In at least one embodiment of this application, one of the heating sleeves is provided with a cover, and the other heating sleeve is provided with a suction part. The cover and the suction part are attracted to each other to cover the receiving cavity.

[0028] The drone battery temperature control sleeve implemented in this embodiment will have at least the following beneficial effects:

[0029] The aforementioned drone battery temperature-controlled sleeve places the drone battery to be heated within its housing cavity.

This effectively maintains the temperature of the drone battery within the housing cavity, ensuring it remains in a stable, insulated environment. When needed, the drone battery can simply be removed from the temperature-controlled sleeve. This avoids issues such as the drone becoming unusable or experiencing reduced battery life due to low battery temperature. Attached Figure Description

[0046] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0047] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0048] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0049] Embodiments of this application provide a drone battery temperature control sleeve 100, comprising:

[0050] The protective sleeve body 110 has a heating sleeve 111. The protective sleeve body 110 has a receiving cavity 110a, and the heating sleeve 111 has a heating cavity 111a. The receiving cavity 110a is used to place the drone battery to be heated.

[0051] A heating element 120 is disposed within the heating cavity 111a;

[0052] A heat-conducting element 130 is disposed within the heating cavity 111a and is attached to the heating element 120;

[0053] During heating, part of the heat generated by the heating element 120 is directly conducted to the accommodating cavity 110a through the heating sleeve 111, and the other part is conducted to the accommodating cavity 110a through the heat-conducting element 130.

[0054] Please refer to Figures 1-6In this embodiment, the drone battery to be heated is placed in the receiving cavity 110a. The heating element 120 generates and releases heat. Part of the heat is released into the heating cavity 111a through heat transfer, and the other part is released into the heating cavity 111a through the heat-conducting element 130. This keeps the drone battery in the receiving cavity 110a at a stable temperature, so that it can be directly removed from the drone battery temperature-controlled sleeve 100 when needed. This avoids the problem of the drone battery becoming unusable or experiencing a decrease in battery life due to low temperature.

[0055] It should be noted that the protective cover body 110 is generally a cover with one end open and a semi-closed cavity structure inside, and is made of flexible material.

[0056] The heating jacket 111 is generally a double-layered sealed jacket and is generally rectangular in shape. The accommodating cavity 110a is generally a semi-closed cavity, and the heating cavity 111a is a sealed cavity. The heating jacket 111 is generally made of a flexible material, such as cloth or leather.

[0057] The heating element 120 is a heating plate or a heating wire. In this embodiment, a heating wire is used, while in another embodiment, a heating plate is used.

[0058] The heat-conducting component 130 is generally a metal heat-conducting plate and is made of heat-conducting material, so that part of the heat generated by the heating component 120 is sealed in the heating cavity 111a through the heat-conducting component 130, thereby keeping the drone battery in the accommodating cavity 110a warm.

[0059] It should be further explained that the heat-conducting component 130 is located on the side of the heating component 120 away from the drone battery, thereby isolating the accommodating cavity 110a from the outside and preventing external cold air from affecting the temperature inside the accommodating cavity 110a.

[0060] In at least one embodiment of this application, the heat-conducting element 130 and the inner wall of the heating cavity 111a form a heat storage channel 130a, and the heating element 120 is disposed in the heat storage channel 130a.

[0061] Please refer to Figures 1-6 In this embodiment, since the heating element 120 is installed in the heat storage channel 130a, part of the heat from the heating element 120 is directly released into the accommodating cavity 110a, and the other part is conducted to the heat-conducting element 130. Since the heat-conducting element 130 is in direct contact with the inner wall of the heating cavity 111a, the heat on the heat-conducting element 130 is released into the accommodating cavity 110a, further increasing the temperature inside the accommodating cavity 110a, resulting in better heat preservation and better heat preservation for the drone battery.

[0062] It should be noted that the heat storage channel 130a is formed by the inward indentation of the side of the heat-conducting element 130 near the heating element 120.

[0063] The heat storage channel 130a can prevent most of the heat from the heating element 120 from being released to the outside, thereby improving the heat preservation effect.

[0064] In at least one embodiment of this application, the heat-conducting element 130 has a first heat-conducting fin 131 and a second heat-conducting fin 132 disposed inclined to the first heat-conducting fin 131, the first heat-conducting fin 131, the second heat-conducting fin 132 and the inner wall of the heating cavity 111a form the heat storage channel 130a.

[0065] Please refer to Figures 1-6 In this embodiment, the first heat-conducting fin 131 and the second heat-conducting fin 132 form a heat storage channel 130a with the inner wall of the heating cavity 111a. The heat storage channel 130a can retain most of the heat of the heating element 120 in the heat storage channel 130a, avoiding the heat loss of the heating element 120 to the external space. The first heat-conducting fin 131 and the second heat-conducting fin 132 can further absorb the heat of the heating element 120 that has not been released into the receiving cavity 110a, thereby keeping this part of the heat in the heating cavity 111a and slowly releasing it into the receiving cavity 110a to ensure the heat preservation effect.

[0066] In at least one embodiment of this application, the heating element 120 is arranged within the heat storage channel 130a.

[0067] Please refer to Figures 1-6 In this embodiment, since the heating element 120 is arranged around the heat storage channel 130a, the heat generated by the heating element 120 can be released more evenly into the heating cavity 111a and into the accommodating cavity 110a through the thermal effect, resulting in better heat preservation and more uniform heat preservation temperature, thus avoiding the problem of damage to the drone battery caused by excessively high local temperature.

[0068] It should be further explained that there is a gap between the heating element 120 and the inner wall of the accommodating cavity 110a, thereby preventing the heating element 120 from directly contacting the inner wall of the accommodating cavity 110a and causing localized temperature damage to the drone battery.

[0069] In at least one embodiment of this application, there are two heating sleeves 111, and the accommodating cavity 110a is formed between the two heating sleeves 111. Each heating sleeve 111 is provided with at least one heating element 120 and at least one heat-conducting element 130.

[0070] Please refer to Figures 1-6In this embodiment, the heating element 120 and the heat-conducting element 130 in the two heating sleeves 111 respectively heat and insulate the two sides of the drone battery, so that the drone battery in the accommodating cavity 110a can be in a stable heat preservation environment, avoiding damage to the drone battery due to low temperature, and also avoiding damage to the drone battery due to excessive local temperature and temperature difference between the two sides.

[0071] In at least one embodiment of this application, the first heat-conducting fin 131 and the second heat-conducting fin 132 form an inclined heat-conducting portion 133, and a bonding heat-conducting portion 134 is provided between two adjacent inclined heat-conducting portions 133. The bonding heat-conducting portion 134 is bonded to the inner wall of the heating cavity 111a on the side close to the other heating sleeve 111.

[0072] Please refer to Figures 1-6 In this embodiment, a portion of the heat from the heating element 120 is directly released into the accommodating cavity 110a through the air, while another portion of the heat is conducted to the bonding heat-conducting part 134 through the inclined heat-conducting part 133, and then released into the accommodating cavity 110a through the bonding heat-conducting part 134, thus avoiding excessive heat loss from the heating element 120.

[0073] Secondly, by tilting the first heat-conducting fin 131 and the second heat-conducting fin 132, the heating element 120 is positioned between the first heat-conducting fin 131 and the second heat-conducting fin 132, thereby improving the efficiency of heat absorption by the tilted heat-conducting part 133 and thus improving the efficiency of heat conduction by the tilted heat-conducting part 133. This ensures the temperature inside the heating cavity 111a and prevents uneven temperature distribution in the heating cavity 111a, which could lead to excessive temperature differences in the drone battery and affect its use.

[0074] It should be noted that the first heat-conducting fin 131 and the second heat-conducting fin 132 are arranged opposite to each other, and the heating cavity 111a formed by the first heat-conducting fin 131 and the second heat-conducting fin 132 and the inner wall of the heating cavity 111a is a triangular heating cavity 111a. By attaching the heat-conducting part 134, part of the heat can be conducted to the accommodating cavity 110a through the heating sleeve 111, and the other part supports the heating sleeve 111 to prevent the drone battery from squeezing the heating sleeve 111, which would cause the heating element 120 to come into direct contact with the heating sleeve 111, thereby causing the local temperature to be too high and damaging the drone battery.

[0075] It should be further noted that the heat-conducting part 134 is roughly a rectangular plate.

[0076] In at least one embodiment of this application, the protective sleeve body 110 further provides an installation cavity 110b;

[0077] The drone battery temperature control sleeve 100 also includes:

[0078] A heating power supply 140 is located in the mounting cavity 110b and is electrically connected to the heating element 120.

[0079] Circuit board 150 is disposed in the mounting cavity 110b and is electrically connected to the heating power supply 140;

[0080] The charging interface 160 is located on the protective cover body 110 and is electrically connected to the circuit board 150.

[0081] Please refer to Figures 1-6 In this embodiment, the heating element 120 is powered by the heating power supply 140, and the circuit board 150 controls the heating temperature of the heating element 120 to prevent overheating and damage to the drone battery. The charging interface 160 is a Type-C interface, a USB interface, or another interface, used to charge the heating power supply 140.

[0082] In at least one embodiment of this application, the protective sleeve body 110 further includes:

[0083] An elastic sleeve 170 is disposed between the two heating sleeves 111;

[0084] A bottom shielding sleeve 180 is disposed between the two heating sleeves 111, and the elastic sleeve 170, the two heating sleeves 111 and the bottom shielding sleeve 180 surround and form the receiving cavity 110a.

[0085] Please refer to Figures 1-6 In this embodiment, the elastic sleeve 170 is disposed between the two heating sleeves 111, so that the space of the accommodating cavity 110a can be adapted to drone batteries of different sizes.

[0086] The bottom shielding sleeve 180, the two elastic sleeves 170 and the two heating sleeves 111 form a receiving cavity 110a, thereby ensuring the sealing of the receiving cavity 110a and preventing external cold air from directly entering the receiving cavity 110a.

[0087] It should be noted that the elastic sleeve 170 is roughly made of elastic cloth and is located on both sides of the two heating sleeves 111, and the bottom shielding sleeve 180 is used to shield the bottom of the receiving cavity 110a.

[0088] Both the elastic sleeve 170 and the bottom cover sleeve 180 are made of materials such as cloth, leather, and elastic fabric.

[0089] It should be further explained that the cavity 110a is provided with protruding ribs. When the drone battery is placed in the cavity 110a, the protruding ribs will directly contact the drone battery, thereby preventing the inner wall of the cavity 110a from directly contacting the drone battery and avoiding damage to the drone battery caused by local heat sources.

[0090] In at least one embodiment of this application, the bottom cover sleeve 180 is provided with cover portions 181 at both ends;

[0091] The elastic sleeve 170 is provided with an adhesive portion 171, and the blocking portion 181 is bonded to the adhesive portion 171 to block the gap at the connection between the bottom blocking sleeve 180 and the elastic sleeve 170.

[0092] Please refer to Figures 1-6 In this embodiment, when heat preservation of a large battery, the distance between the two heating sleeves 111 can be changed by the elastic sleeve 170 to adapt to batteries of different specifications. The shielding part 181 and the adhesive part 171 are bonded together to block the gap at the connection between the bottom shielding sleeve 180 and the elastic sleeve 170, preventing external air from entering the accommodating cavity 110a through this point, and also preventing the heat in the accommodating cavity 110a from being released to the outside through this point, so that the heat preservation effect in the accommodating cavity 110a is better.

[0093] In at least one embodiment of this application, one of the heating sleeves 111 is provided with a cover 1111, and the other heating sleeve 111 is provided with a suction part 1112. The cover 1111 and the suction part 1112 are attracted to each other to cover the accommodating cavity 110a.

[0094] Please refer to Figures 1-6 In this embodiment, the shielding cover 1111 and the suction part 1112 are suctioned together to seal the accommodating cavity 110a, thereby preventing the heat inside the accommodating cavity 110a from being released to the external space and improving the heat preservation effect inside the accommodating cavity 110a.

[0095] It should be noted that the cover 1111 is made of a flexible material. The cover 1111 is equipped with a magnetic element and the suction part 1112 is equipped with a magnet. The magnetic element and the magnet attract each other, thereby achieving the effect of blocking the accommodating cavity 110a and improving the heat preservation effect inside the accommodating cavity 110a.

[0096] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
