Description

Technical Field

[0001] This invention belongs to the field of engine preheating technology, specifically relating to a low-temperature preheating device and system for robots. Background Technology

[0002] A robot is a machine device that automatically performs tasks. Its task is to assist or replace humans in work, such as performing dangerous tasks in manufacturing and construction. Currently, some vehicles can also be called robots. These vehicles are generally equipped with sensors, control systems, navigation systems, and other devices, enabling them to perform tasks automatically. These vehicles can be called vehicle-shaped robots.

[0003] Some vehicle-shaped robots are oil-powered, featuring an oil tank and an engine. The engine can be exposed or internal. When the robot starts working, the engine draws in air to power it. In cold weather, low-temperature air entering the engine can affect its starting and operation, potentially causing the following problems: First, fuel evaporation: cold air reduces the evaporation rate of gasoline, making it difficult for fuel to evaporate into fine atomized particles. This can lead to an overly rich or uneven air-fuel mixture, making it difficult to start or causing unstable engine operation. Second, air density: cold air is denser and contains more oxygen, theoretically providing better combustion. However, if the fuel supply system is not effectively adjusted, excessively high air density can result in an overly lean air-fuel mixture, affecting normal engine starting and operation. Currently, engine preheating typically involves heating the oil in the oil tank to warm the internal engine structure. However, low-temperature air entering the engine can easily affect the effectiveness of this preheating method. Summary of the Invention

[0007] In some embodiments, a first external preheating mechanism is further included. The first external preheating mechanism includes a third heating element, a third heat-conducting element, a first adhesive element, and a second adhesive element. The first adhesive element is connected to the third heating element, and the second adhesive element is connected to the third heat-conducting element. The third heating element can be bonded to the third heat-conducting element through the bonding of the first adhesive element and the second adhesive element. The third heating element is used to heat the third heat-conducting element so that the third heat-conducting element heats the engine body housing. The first external preheating mechanism is in a preheating state. When the first external preheating mechanism is in a preheating state, the third heat-conducting component is laid on the outside of the engine body part.

[0008] In some embodiments, the first external preheating mechanism is configured as a plurality of such mechanisms.

[0009] In some embodiments, a plurality of bonding mechanisms are installed on the third heating element. The bonding mechanisms are used to fix the first external preheating mechanism to the outside of the engine body portion. Each bonding mechanism includes a third connector installed on the third heating element, a first elastic member connected to the third connector, a first mating member connected to the first elastic member, and a second mating member connected to the third connector.

[0010] In some embodiments, at least some of the bonding mechanisms are disposed at both ends of the third heating element along the extending direction of the third heating element.

[0011] In some embodiments, a second external preheating mechanism is further included. The second external preheating mechanism is used to heat the engine body casing. The second external preheating mechanism includes an air supply section, an air duct, and a connecting section that are detachably connected to the engine body.

The second external preheating mechanism has a first preheating state and a second preheating state. When the second external preheating mechanism is in the first preheating state, the air duct is sleeved on the outside of the engine body shell and has a spiral structure. When the second external preheating mechanism is in the second preheating state, the air duct is set close to a part of the engine body shell.

[0012] In some embodiments, a plurality of second external preheating mechanisms are provided.

[0013] In some embodiments, the second external preheating mechanism includes at least one support component, the support component includes a plurality of hollow sections arranged in parallel, a plurality of fourth connectors whose two ends are respectively connected to different hollow sections, and a fifth connector is connected to any one of the hollow sections; all the fourth connectors are configured as retractable structures. All hollow sections have hollow cavities. When the second external preheating mechanism is in the first preheating state or the second preheating state, the fifth connector is detachably connected to the air supply section, and the air duct passes through each hollow cavity.

[0014] In some embodiments, the hollow portion includes a first enclosure member and a second enclosure member rotatably connected to the first enclosure member, wherein the first enclosure member and the adjacent second enclosure member can enclose a hollow cavity. The fifth connector is connected to the corresponding first enclosure, and the fourth connector is connected to the corresponding first enclosure; The hollow section also includes a third connecting member connected to the first enclosure and a fourth connecting member connected to the second enclosure.

[0015] In some embodiments, the device further includes a pressing mechanism, which includes a lifting member positioned above the third heating member and a plurality of second elastic members connected to the side of the lifting member near the third heating member, all of which are detachably connected to the third heating member. The extrusion mechanism also includes a linkage component, with its two ends connected to the lifting member and the output end of the drive unit, respectively. When the output end of the drive unit moves away from the third heating member along the lifting member, the output end of the drive unit can drive the linkage component to cause the second elastic member to extrude the third heating member.

[0016] In some embodiments, the extrusion mechanism further includes at least one extrusion member disposed on one side of the lower end region of the third heating member, and a plurality of third elastic members are connected to the side of the extrusion member near the third heating member, and the third elastic members are all detachably connected to the third heating member.

When the lifting element moves in a direction close to the third heating element, the lifting element can push the extrusion element to extrude the third elastic element through the fourth elastic element, so that the third elastic element extrudes the lower region of the third heating element.

[0017] The beneficial effects of this invention are: 1. In this invention, by setting up a preheating component, when air enters the air intake, it needs to pass through a preheating chamber first. During the passage process, the first and second heat-conducting components, which have been heated by the first and second heating components, can heat the air to avoid a large amount of low-temperature air entering the engine body and thus affecting the operation of the engine body.

[0018] 2. In the preheating assembly, the first heat-conducting mechanism includes a plurality of first heat-conducting elements spaced apart along the extension direction of the preheating cavity, and the second heat-conducting mechanism includes a plurality of second heat-conducting elements spaced apart along the extension direction of the preheating cavity.

At the same time, the first heat-conducting elements and the second heat-conducting elements are staggered. This arrangement can guide the airflow to avoid the air passing through the preheating cavity too quickly, thereby extending the time period during which at least part of the air can be heated. At the same time, it can increase the contact area between the heating structure and the air, thereby improving the heating effect on the air, and can prevent the air from being unable to flow along the surface of the heating structure, thereby preventing some air from being blocked and unable to pass through the preheating cavity.

[0019] 3. In this invention, by setting up the bonding mechanism, the third heat-conducting component can be bonded to the engine body, while the first external preheating mechanism can be fixed to the outside of the engine body. At the same time, it is convenient to quickly disassemble the first external preheating mechanism and each bonding mechanism. Attached Figure Description

Example 1

[0024] like Figures 1 to 9 As shown, a low-temperature preheating device for robots includes: Engine body 1, with an air intake; The preheating component 100 is located on one side of the air intake and is used to preheat the air entering the engine body 1. and fixing component 200, used to fix preheating component 100 to one side of air inlet; The preheating assembly 100 includes a preheating box 110 located on one side of the air inlet, a first heating element 120, a second heating element, a first heat-conducting mechanism 140, and a second heat-conducting mechanism 150. The preheating box 110 has a preheating cavity and includes a box body 111 and a box cover 112. The box body 111 and the box cover 112 enclose the preheating cavity. The box body 111 has an air outlet 1113 corresponding to the air inlet and a first placement groove communicating with the preheating cavity. The first heating element 120 is placed in the first placement groove. The box cover 112 is slidably connected to the side of the box body 111 away from the engine body 1. The box cover 112 has a second placement groove communicating with the preheating cavity. The second heating element is placed in the second placement groove. The first heat-conducting mechanism 140 is placed in the preheating cavity. The first heat-conducting mechanism 140 includes a plurality of first heat-conducting elements spaced apart along the extension direction of the preheating cavity. The first heat-conducting elements are all detachably installed on the first heating element 120. The surfaces of the first heat-conducting elements near the opening of the preheating cavity are all inclined in a direction away from the opening of the preheating cavity. The second heat-conducting mechanism 150 is placed in the preheating cavity. The second heat-conducting mechanism 150 includes a plurality of second heat-conducting elements spaced apart along the extension direction of the preheating cavity. The second heat-conducting elements are all detachably installed on the second heating element. The surfaces of the second heat-conducting elements near the opening of the preheating cavity are all inclined in a direction away from the opening of the preheating cavity. The first heat-conducting elements and the second heat-conducting elements are staggered. The fixing component 200 is detachably connected to the housing 111 and the engine body 1, respectively.

[0025] It should be noted that if the air entering the engine is too cold, it will affect the engine's starting and operation. Specifically, some of the problems that may occur are as follows: First, fuel evaporation. Cold air reduces the evaporation rate of gasoline, making it difficult for fuel to evaporate into fine atomized particles. This can lead to an overly rich or uneven air-fuel mixture, making the engine difficult to start or causing unstable operation. Second, air density. Cold air has a higher density and contains more oxygen, theoretically providing better combustion. However, if the fuel supply system cannot be effectively adjusted, excessively high air density may result in an overly lean air-fuel mixture, affecting the engine's normal starting and operation.

[0026] In this invention, the engine body 1 is one of the core structures of the robot, which is used to drive the robot to move. During the operation of the engine body 1, air enters the engine body 1 through the air inlet. When the preheating component 100 is put into use, at least part of the air entering the engine body 1 can be heated by the preheating component 100 to increase its temperature, so as to avoid the operation of the engine body 1 being affected by the low air temperature. The fixing component 200 is used to fix the preheating mechanism to one side of the engine body 1.

[0027] Regarding the engine body 1, it should be noted that, as one of the robot's combined structures, the engine body 1 can be either an exposed structure or an internal structure. When it is an exposed structure, the safety of the engine body 1 is improved; when it is an internal structure, the maintenance difficulty of the engine body 1 is reduced. The engine body 1 is controlled by a controller or other control devices on the robot. In this invention, all control structures other than the engine body 1 can be controlled by a controller or other control devices on the robot.

[0028] With the preheating component 100, air must pass through the preheating chamber before entering the air inlet. During this process, the first and second heat-conducting components, heated by the first heating element 120 and the second heating element, can heat the air to prevent a large amount of low-temperature air from entering the engine body 1 and affecting its operation. The first heating element 120 and the second heating element can be selected as electric heating plates and can be controlled by a controller or other control device on the robot. The first and second heat-conducting components can be selected as heat-conducting plates.

[0029] Several points need to be noted regarding the preheating assembly 100: First, air can be directly heated via the first heating element 120 and the second heating element. However, using this method, the area of ​​the heated structure in the preheating assembly 100 that can contact the air is relatively small, and it is not easy to guide the airflow. Second, the first heating element 120 and the second heating element can be connected to the corresponding structure in a detachable manner. Furthermore, by providing a cover 112 that can be separated from the housing 111, it is convenient to inspect and maintain the first heating element 120, the first heat-conducting element, and other structures. Third, in the preheating assembly 100, the first heat-conducting mechanism 140 includes multiple first heat-conducting elements spaced apart along the extension direction of the preheating chamber, and second heat-conducting elements... The mechanism 150 includes a plurality of second heat-conducting elements spaced apart along the extension direction of the preheating cavity. The surfaces of the first heat-conducting elements near the opening of the preheating cavity are all inclined in a direction away from the opening of the preheating cavity, and the surfaces of the second heat-conducting elements near the opening of the preheating cavity are all inclined in a direction away from the opening of the preheating cavity. At the same time, the first heat-conducting elements and the second heat-conducting elements are staggered. This arrangement can guide the airflow to avoid the air passing through the preheating cavity too quickly, thereby extending the time period during which at least part of the air can be heated. It can also increase the contact area between the heating structure and the air, thereby improving the heating effect on the air, and can prevent the air from being unable to flow along the surface of the heating structure, thereby preventing some air from being blocked and unable to pass through the preheating cavity.

[0030] It should be noted that the "detachable connection" in this invention can be selected as a threaded connection, snap-fit, adhesive connection, etc., depending on the actual situation, and there is no specific limitation.

[0031] In some embodiments, the housing 111 includes a first splicing component 1111 and a second splicing component 1112, the housing cover 112 is slidably connected to the second splicing component 1112, the first placement groove is provided on the second splicing component 1112, and the fixing component 200 is detachably connected to the first splicing component 1111. The second splicing piece 1112 is connected to the first connector 2, which is slidably connected to the first splicing piece 1111. The first splicing piece 1111 is provided with a driving part 3, and the output end of the driving part 3 is connected to the second connector 4. The driving part 3 can drive the second connector 4 to push the first connector 2 and the second splicing piece 1112 to move, so that the first splicing piece 1111 fits into the second splicing piece 1112.

[0032] The drive unit 3 can be configured as a cylinder. The drive unit 3 can drive the second connecting member 4 to push the first connecting member 2 and the second splicing member 1112 to move, so that the first splicing member 1111 fits into the second splicing member 1112. At this time, air needs to enter the engine body 1 through the preheating chamber. When the drive unit 3 is not started, the first splicing member 1111 and the second splicing member 1112 are separated. At this time, air can directly enter the engine body 1 through the air intake.

[0033] With the above settings, there are multiple paths for air to enter the engine body 1, so it is possible to select whether to preheat the air entering the engine body 1 according to the outside temperature.

[0034] In some embodiments, a first external preheating mechanism 300 is further included. The first external preheating mechanism 300 includes a third heating element 310, a third heat-conducting element 320, a first adhesive element 330, and a second adhesive element 340. The first adhesive element 330 is connected to the third heating element 310, and the second adhesive element 340 is connected to the third heat-conducting element 320. The third heating element 310 can be bonded to the third heat-conducting element 320 by bonding the first adhesive element 330 and the second adhesive element 340. The third heating element 310 is used to heat the third heat-conducting element 320 so that the third heat-conducting element 320 heats the outer shell of the engine body 1. The first external preheating mechanism 300 is in a preheating state. When the first external preheating mechanism 300 is in a preheating state, the third heat-conducting component 320 is laid on the outside of a part of the engine body 1.

[0035] It is important to note that in cold weather, in addition to heating the internal structure of the engine body 1 and the air entering the engine body 1, the external structure of the engine body 1 also needs to be heated to avoid at least the following problems: First, shortened component lifespan. Each component of the engine needs to reach an appropriate operating temperature during a cold start to function properly. If only the internal parts of the engine are heated without heating the external parts, the temperature of the external components may be too low, easily increasing friction and wear between components, thus shortening their lifespan. Second, insufficient external cooling. The engine generates a large amount of heat during operation, which needs to be dissipated into the outside air through the cooling system. If the external temperature of the engine is too low, the cooling effect will be affected, potentially leading to overheating and damage.

[0036] With the provision of the first external preheating mechanism 300, at least a portion of the external structure of the engine body 1 can be heated, thereby avoiding negative impacts such as shortened lifespan of engine body 1 parts due to low temperatures in various parts of the external structure of the engine body 1.

[0037] In the first external preheating mechanism 300, the third heating element 310 can be heated by an electric heating blanket for the engine, and the third heat conducting element 320 can be heated by a heat conducting pad. The third heating element 310 can be bonded to the third heat conducting element 320 by the bonding of the first adhesive element 330 and the second adhesive element 340. During heating, the third heating element 310 heats the third heat conducting element 320, and then the third heat conducting element 320 heats the external structure of the engine body 1 to avoid the external structure of the engine body 1 from getting too hot.

[0038] It should be noted that the first external preheating mechanism 300 is mainly used when the engine body 1 is an exposed structure. In this case, the first external preheating mechanism 300 can cover the remaining area of ​​the engine body 1 except for the bottom area or cover the upper area of ​​the engine body 1. When there are many protruding structures on the engine body 1, multiple first external preheating mechanisms 300 can also be used in combination to heat at least most of the external structure of the engine body 1.

[0039] In some embodiments, the first external preheating mechanism 300 is configured as a plurality of units.

[0040] In some embodiments, a plurality of bonding mechanisms 400 are installed on the third heating element 310. The bonding mechanisms 400 are used to fix the first external preheating mechanism 300 to the outside of a portion of the engine body 1. Each bonding mechanism 400 includes a third connector 410 installed on the third heating element 310, a first elastic member 420 connected to the third connector 410, a first mating member 430 connected to the first elastic member 420, and a second mating member 440 connected to the third connector 410.

[0041] The bonding mechanism 400 is used to promote the bonding of the third heat-conducting element 320 to the engine body 1, so as to improve the heating effect on the external structure of the engine body 1. Specifically, when a single first docking element 430 docks with a second docking element 440 that is in a different bonding structure, for example, the first docking element 430 is located at one end of the third heating element 310 and the second docking element 440 is located at the other end of the third heating element 310, when the corresponding first elastic element 420 deforms, it can promote the two ends of the third heating element 310 to move closer to the engine body 1.

[0042] By setting the bonding mechanism 400, the third heat-conducting component 320 can be bonded to the engine body 1, while the first external preheating mechanism 300 can be fixed to the outside of the engine body 1. At the same time, it is convenient to quickly disassemble the first external preheating mechanism 300 and each bonding mechanism 400.

[0043] In some embodiments, at least a portion of the plurality of bonding mechanisms 400 are disposed at both ends of the third heating element 310 along the extending direction of the third heating element 310.

[0044] In some embodiments, a second external preheating mechanism 500 is further included. The second external preheating mechanism 500 is used to heat the outer shell of the engine body 1. The second external preheating mechanism 500 includes an air supply section 510, an air duct 520, and a connecting section 530 detachably connected to the engine body 1. The air supply section 510 has an air supply port, the air duct 520 has an air inlet and a plurality of air outlets, and the connecting section 530 has a connecting cavity. The two ends of the connecting section 530 are detachably connected to the air supply section 510 and the air duct 520, respectively. The two ends of the connecting cavity are connected to the air supply port and the air inlet, respectively. The second external preheating mechanism 500 has a first preheating state and a second preheating state. When the second external preheating mechanism 500 is in the first preheating state, the air duct 520 is sleeved on the outside of the engine body 1 and has a spiral structure. When the second external preheating mechanism 500 is in the second preheating state, the air duct 520 is set close to a part of the engine body 1.

[0045] It should be noted that the use of the first external preheating mechanism 300 is not advisable in some cases, such as when the engine body 1 is far from the power source, or when it is necessary to further increase the heating speed of the external structure of the engine body 1.

[0046] The second external preheating mechanism 500 can replace the first external preheating mechanism 300 or work in conjunction with the first external preheating mechanism 300, depending on factors such as the composition of the robot, weather conditions, the position of the robot, and the position of the engine body 1 on the robot.

[0047] The second external preheating mechanism 500 has a first preheating state and a second preheating state. When the second external preheating mechanism 500 is in the first preheating state, the air duct 520 is sleeved on the outside of the engine body 1 shell and has a spiral structure. When the second external preheating mechanism 500 is in the second preheating state, the air duct 520 is set close to a portion of the engine body 1 shell. The position of the engine body 1 on the robot is varied; it can be an internal structure, an exposed structure, or a structure where some parts are exposed and some parts are internal. When the air duct 520 can pass through the lower area of ​​the engine body 1, the air duct 520 is sleeved on the outside of the engine body 1 shell and has a spiral structure, thereby heating the bottom area of ​​the engine body 1. When the air duct 520 cannot pass through the lower area of ​​the engine body 1, the air duct 520 is set close to a portion of the engine body 1 shell, in which case the area of ​​the engine body 1 other than the bottom or lower end area can be heated.

[0048] The air supply unit 510 can be configured as a hot air blower. By using hot air heating, it is possible to avoid the inability to heat the various parts of the engine body 1 evenly when there are many protruding structures on the outside of the engine body 1.

[0049] In some embodiments, the second external preheating mechanism 500 is configured as a plurality of units.

[0050] In some embodiments, the second external preheating mechanism 500 includes at least one support component 540. The support component 540 includes a plurality of hollow portions 541 arranged in parallel and a plurality of fourth connectors 542 whose two ends are respectively connected to different hollow portions 541. A fifth connector 5 is connected to any one of the hollow portions 541. All fourth connectors 542 are configured as retractable structures. All hollow sections 541 have hollow cavities. When the second external preheating mechanism 500 is in the first preheating state or the second preheating state, the fifth connector 5 is detachably connected to the air supply section 510, and the air duct 520 passes through each hollow cavity.

[0051] The support assembly 540 can support the air duct 520, thereby fixing each part of the air duct 520 in a predetermined position and preventing the predetermined heating area in the external structure of the engine body 1 from not being heated.

[0052] When the second external preheating mechanism 500 is in the first preheating state or the second preheating state, the air duct 520 is inserted into each hollow cavity. At the same time, the fifth connector 5 is detachably connected to the air supply part 510, so that the hollow part 541 can be fixed in the predetermined area to support the air duct 520.

[0053] It should be noted that the air duct 520 can be in a spiral or other structure during operation, while the support component 540 is used to stabilize the air duct 520 so that it maintains its structural shape, and also facilitates the quick installation and disassembly of the air duct 520.

[0054] In some embodiments, the hollow portion 541 includes a first enclosure 5411 and a second enclosure 5412 rotatably connected to the first enclosure 5411. The first enclosure 5411 and the adjacent second enclosure 5412 can form a hollow cavity. The fifth connector 5 is connected to the corresponding first enclosure 5411, and the fourth connector 542 is connected to the corresponding first enclosure 5411; The hollow portion 541 also includes a third docking member 5413 connected to the first enclosure member 5411 and a fourth docking member 5414 connected to the second enclosure member 5412.

[0055] Through the docking of the third docking member 5413 and the fourth docking member 5414, the first enclosure member 5411 can fit against the adjacent second enclosure member 5412 and form a hollow cavity with the adjacent second enclosure member 5412. When installing the air duct 520, the air duct 520 can be inserted into each hollow cavity first and then the air duct 520 and the support assembly 540 can be fixed. Alternatively, the air duct 520 can be fixed first and then inserted into each hollow cavity. The latter method can avoid the support assembly 540 from obstructing the placement of each part of the air duct 520 in the predetermined area. At the same time, it can also avoid repeatedly adjusting the length of the fourth connector 542.

[0056] In some embodiments, the device further includes a pressing mechanism 600, which includes a lifting member 610 positioned above the third heating member 310 and a plurality of second elastic members 620 connected to the side of the lifting member 610 near the third heating member 310. The second elastic members 620 are all detachably connected to the third heating member 310. The extrusion mechanism 600 also includes a linkage component 630, the two ends of which are connected to the lifting member 610 and the output end of the drive unit 3, respectively. When the output end of the drive unit 3 moves away from the third heating member 310 along the lifting member 610, the output end of the drive unit 3 can drive the linkage component 630 to cause the second elastic member 620 to extrude the third heating member 310.

[0057] The second elastic element 620 can be configured as a spring or similar structure, and the linkage assembly 630 can refer to an existing seesaw structure. When the output end of the drive unit 3 moves away from the third heating element 310 along the lifting member 610, the output end of the drive unit 3 can drive the linkage assembly 630 to cause the second elastic element 620 to press against the third heating element 310, thereby causing a portion of the third heat-conducting element 320 to stably adhere to the outer shell of the engine body 1. At the same time, this avoids the need for multiple adhesion mechanisms 400.

[0058] In some embodiments, the extrusion mechanism 600 further includes at least one extrusion member 640 disposed on one side of the lower end region of the third heating member 310. A plurality of third elastic members 650 are connected to the side of the extrusion member 640 near the third heating member 310. All the third elastic members 650 are detachably connected to the third heating member 310. The extrusion mechanism 600 also includes at least one fourth elastic element 660, one end of which is connected to the lifting member 610. When the lifting member 610 moves in a direction close to the third heating member 310, the lifting member 610 can push the extrusion member 640 to extrude the third elastic element 650 through the fourth elastic element 660, so that the third elastic element 650 extrudes the lower region of the third heating member 310.

[0059] The third elastic element 650 can be referenced to the headband structure. When the lifting element 610 moves in the direction close to the third heating element 310, the lifting element 610 can push the pressing element 640 to press the third elastic element 650 through the fourth elastic element 660, so that the third elastic element 650 presses the lower end area of ​​the third heating element 310, thereby achieving more stable contact between the third heat conducting element 320 and the outer shell of the engine body 1. Example 2

[0060] A cryogenic preheating system for robots includes the locking device described in the above embodiments.

[0061] In summary, in this invention, by setting up the preheating component 100, when air enters the air intake, it needs to pass through the preheating chamber first. During the passage process, the first heat-conducting component and the second heat-conducting component, which have been heated by the first heating component 120 and the second heating component, can heat the air to avoid a large amount of low-temperature air entering the engine body 1 and thus affecting the operation of the engine body 1.
