Technical Field
[0001] This application relates to the field of electromechanical equipment technology, and in particular to a water propulsion device and a water mobile device. Background Technology
[0002] The thruster is the power unit for aquatic mobile equipment, used to propel the equipment across water. The battery, as the power source for the thruster, needs to be stably mounted on a battery holder. Because the aquatic thruster is susceptible to vibration due to the reaction force of the water, the battery on the thruster can easily become loose under vibration, resulting in the battery failing to provide power. Utility Model Content
[0003] This application provides a water propulsion device with enhanced battery mounting stability.
[0004] This application provides a water propulsion device, including a body and a battery. One end of the body is provided with an underwater propulsion device for outputting propulsion power. The other end of the body is provided with a battery holder. The battery holder includes a base supporting the bottom of the battery and a side frame limiting the end of the battery. The side frame is provided with a slot at the end away from the base. The top of the battery is provided with a rotatable hook. The slot has a first side and a second side. The second side is located on a rotation axis close to the hook relative to the first side.
[0005] When the battery is subjected to vibration force, causing the hook to move towards the base, the first side abuts against the hook to limit the movement of the hook towards the base.
[0006] When the battery is subjected to vibration, causing the hook to move away from the base, the second side abuts against the hook to limit the movement of the hook away from the base.
[0007] This application provides a water-based mobile device, including a water-based carrier and the aforementioned water-based thruster. The water-based thruster further includes a clamp connected to the body of the device, and the clamp is connected to the water-based carrier.
[0008] The water propulsion device provided in this application, when the battery is installed in the battery holder via a hook, can keep the hook in the slot regardless of whether it moves toward or away from the base under the action of the battery, thereby keeping the battery locked on the battery holder, thus enhancing the stability of the battery installed on the battery holder and effectively preventing the battery from falling out.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, this application embodiment provides a water propulsion device 10. By setting the first side 51 and the second side 52 of the slot 5 to limit the hook 6 respectively, the slot 5 can limit the hook 6 when the battery 2 is moved by the vibration force, thereby preventing the hook 6 from being dislodged from the slot 5 by force and enhancing the installation stability of the battery 2.
[0034] The following is in conjunction with the appendix Figure 1 To be continued Figure 10 This application provides a detailed description of some embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0035] like Figure 1 , Figure 3 and Figure 4 As shown, the water propulsion device 10 provided in this application embodiment includes a body 1 and a battery 2. One end of the body 1 is provided with an underwater propulsion device 3, which is used to output propulsion power to move the body 1. The other end of the body 1 is provided with a battery holder 4. The battery holder 4 includes a base support 41 supporting the bottom of the battery 2 and a side frame 42 limiting the end of the battery 2. The side frame 42 is provided with a slot 5 at the end away from the base support 41. The top of the battery 2 is provided with a rotatable hook 6. The slot 5 has a first side 51 and a second side 52. The second side 52 is located on the rotation axis 61 of the hook 6 relative to the first side 51. Specifically, the first side 51 and the second side 52 are arranged radially along the rotation axis 61.
[0036] Furthermore, when the battery 2 is subjected to vibration and the hook 6 moves towards the base 41, the first side 51 abuts against the hook 6, for example, the first side 51 abuts against the side of the hook 6 away from the rotation axis 61, to limit the movement of the hook 6 towards the base 41, thereby preventing the hook 6 from continuing to move towards the base 41 and keeping the hook 6 within the slot 5 to prevent the hook 6 from detaching from the slot 5; when the battery 2 is subjected to vibration and the hook 6 moves away from the base 41, the second side 52 abuts against the hook 6, for example, the second side 52 abuts against the side of the hook 6 near the rotation axis 61, to limit the movement of the hook 6 away from the base 41, thereby preventing the hook 6 from continuing to move away from the base 41 and keeping the hook 6 within the slot 5 to prevent the hook 6 from detaching from the slot 5.
[0037] It is understandable that when the battery 2 is installed in the battery holder 4 via the hook 6, the hook 6 can be limited in the slot 5 regardless of whether it moves towards or away from the base 41 under the action of the battery 2, so as to keep the battery 2 locked on the battery holder 4, thereby enhancing the stability of the battery 2 installed on the battery holder 4 and effectively preventing the battery 2 from coming out.
[0038] Combination Figure 1 In one specific embodiment, the underwater propulsion device 3 can use an electric motor to output power. For example, the underwater propulsion device 3 includes an electric motor (not shown) and a propeller (not shown). The electric motor is connected to the propeller and is used to drive the propeller to rotate to generate thrust.
[0039] like Figure 3 and Figure 4 As shown, in some embodiments, the end of the hook 6 that can be inserted into the slot 5 has a first arc surface 62 and a second arc surface 63. Thus, when the first arc surface 62 abuts against the first side surface 51, the side of the hook 6 away from the rotation axis 61 forms a point contact with the first side surface 51. Here, point contact means... Figure 4 The first arc surface 62 in the middle of the cross section and the first side surface 51 are at the arc line of the cross section shown. Figure 4 The straight lines of the cross-section shown form point contact. Also, when the second arc surface 63 and the second side surface 52 are in contact, the side of the hook 6 near the rotation axis 61 also forms point contact with the second side surface 52. Here, point contact means... Figure 4 The second arc surface 62 in the middle of the cross section and the second side surface 52 are at the curve of the cross section shown. Figure 4 The straight lines of the cross-section shown form point contact. The first arc surface 62 points... Figure 4 The arc shown is perpendicular to Figure 4 This illustrates an arc extending in a planar direction. The second arc, 63, refers to... Figure 4 The arc shown is perpendicular to Figure 4 The diagram illustrates an arcuate surface extending in the planar direction. Further, when the first side surface 51 and the first arcuate surface 62 are in contact, the resisting force exerted on the first arcuate surface 62 by the first side surface 51 is directed towards the side of the hook 6's rotation axis 61 away from the base 41. In this case, the resisting force on the first arcuate surface 62 is perpendicular to the first side surface 51. Moreover, one component of this resisting force is parallel to the lever arm of the hook 6 and does not affect the hook 6. The other component of this resisting force is directed towards the groove 5 (i.e., the direction in which the hook 6 engages with the groove 5, defined as the first direction), causing the end of the hook 6 to move deeper into the groove 5, thereby limiting the hook 6 within the groove 5 and preventing the hook 6 from disengaging. When the second side surface 52 and the second arc surface 63 are in contact with each other, the force exerted by the second side surface 52 on the second arc surface 63 is directed away from the rotation axis 61 of the hook 6 and closer to the base 41. In this case, the force exerted by the second arc surface 63 is perpendicular to the second side surface 52. Moreover, one component of the force is parallel to the lever arm of the hook 6 and does not affect the hook 6. The other component of the force is directed toward the inside of the slot 5 (i.e., the first direction, which is also the direction in which the hook 6 is inserted into the slot 5), causing the end of the hook 6 to move deeper into the slot 5 to limit the hook 6 within the slot 5 and prevent the hook 6 from detaching from the slot 5.
[0040] like Figure 3 and Figure 4As shown, in some specific scenarios, with Figure 4 Taking the indicated direction as a reference, when subjected to vibration, battery 2 can rotate counterclockwise around the fulcrum of battery holder 4, causing the first arc surface 62 to abut against the first side surface 51 in a point-contact manner. In this case, the rotational lever arm of the first arc surface 62 of hook 6 is greater than zero, and the angle A1 between the straight line from the point of force application of hook 6 to the fulcrum of battery holder 4 and the direction of force application of the first arc surface 62 of hook 6 is less than 90°. When subjected to vibration, battery 2 can also rotate clockwise around the fulcrum of battery holder 4, causing the second arc surface 63 to abut against the second side surface 52 in a point-contact manner. In this case, the rotational lever arm of the second arc surface 63 of hook 6 is greater than zero, and the angle A2 between the straight line from the point of force application of hook 6 to the fulcrum of battery holder 4 and the direction of force application of the second arc surface 63 of hook 6 is greater than 90°.
[0041] like Figure 3 and Figure 4 As shown, and combined with each Figure 9 and Figure 10 The force analysis diagram analyzes the supporting force of the first side 51 on the first arc surface 62 and the supporting force of the second side 52 on the second arc surface 63. Among them, the hook 6 is a rigid component and the battery 2 is also a rigid component. Therefore, the hook 6 rotating around the rotation axis 61 can be equivalent to the crank Q1 rotating around the hinge A1. The battery 2 rotating around the fulcrum of the battery holder 4 can be equivalent to the crank Q2 rotating around the hinge A2. The first side 51 is equivalent to the first plane P1 and the second side 52 is equivalent to the second plane P2. The first plane P1 and the second plane P2 are set at an angle. The first arc surface 62 is equivalent to the first curved surface X1 and the second arc surface 63 is equivalent to the second curved surface X2. It can be seen that the curved surface and the plane are in a supporting state. The curved surface and the plane are subjected to point-to-surface forces. Therefore, the force direction of the curved surface is perpendicular to the plane.
[0042] Specifically, when the battery 2 is subjected to vibration and rotates counterclockwise to drive the hook 6 to move towards the base 41, the first arc surface 62 of the hook 6 is supported by the first side surface 51. That is, when the crank Q2 rotates clockwise to drive the crank Q1 to rotate clockwise, the first curved surface X1 is supported by the first plane P1. F1 is decomposed into a force F11 parallel to the crank Q1 and a force F12 perpendicular to the crank Q1. Since F11 is parallel to the crank Q1, F11 will not cause the crank Q1 to rotate. The direction of F12 is towards the groove 5 (that is, the direction in which the hook 6 is inserted into the groove 5). Therefore, F12 can cause the end of the hook 6 that can be inserted into the groove 5 to move deeper into the groove 5 to form a self-locking mechanism.
[0043] When the battery 2 is subjected to vibration and rotates clockwise, it causes the hook 6 to move away from the base 41. The second arc surface 63 of the hook 6 is supported by the second side surface 52. That is, the crank Q2 rotates counterclockwise, causing the crank Q1 to have a counterclockwise rotation tendency. The second arc surface X2 is supported by the second plane P2. F2 is decomposed into a force F21 parallel to the crank Q1 and a force F22 perpendicular to the crank Q1. Since F21 is parallel to the crank Q1, F21 will not cause the crank Q1 to rotate. The direction of F22 is towards the groove 5 (that is, the direction in which the hook 6 is inserted into the groove 5). Therefore, F22 can cause the end of the hook 6 that can be inserted into the groove 5 to move deeper into the groove 5 to form a self-locking mechanism.
[0044] As can be understood from the above, the shaking of battery 2 and its clockwise and counterclockwise rotation around the fulcrum of battery holder 4 will cause the end of hook 6 that can be engaged in slot 5 to move in the first direction. Thus, the end of hook 6 that can be engaged in slot 5 moves deeper into slot 5 and engages in slot 5. Therefore, even when subjected to external force (such as the force applied to hook 6 when battery 2 is shaken by vibration), hook 6 can still keep battery 2 locked on battery holder 4, preventing battery 2 from loosening when shaking, and improving the protection of battery 2.
[0045] Combination Figure 3 In some embodiments, the base 41 is provided with a limiting buckle (not shown) to limit the bottom of the battery 2, thereby restricting the movement of the battery 2 and enhancing the installation stability of the battery 2. In one specific embodiment, the limiting buckle is located on the side of the base 41 away from the side frame 42, so as to abut against the bottom of the battery 2 on the side away from the side frame 42. Combined with the side frame 42 limiting the end of the battery 2, the forward and backward movement of the battery 2 can be restricted.
[0046] like Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments, the hook 6 is provided with a handle 64, which is connected to the rotating shaft 61. The handle 64 can drive the rotating shaft 61 to rotate under the action of external force, thereby driving the hook 6 to rotate. The side of the battery 2 away from the hook 6 is provided with a hand-held part (not shown in the figure), which is used for the operator to hold. When the handle 64 is moved away from the base 41 by external force, the hook 6 slides out of the slot 5, and the hand-held part and the handle 64 are simultaneously subjected to external force away from the base 41, so that the battery 2 moves away from the base 41, thereby realizing the removal of the battery 2 from the battery holder 4.
[0047] In this embodiment, both the handle 64 and the hook 6 rotate around the rotating shaft 61. The operator holds the handle 64 and the handheld part respectively, and applies a force to the handle 64 to make it rotate, causing the handle 64 to move away from the base 41. This causes the hook 6 to slide out of the slot 5, thus unlocking the hook 6. On this basis, the operator also applies a force to the handle 64 to move away from the base 41, and applies a force to the handheld part to move away from the base 41, so as to pull the battery 2 away from the base 41, thereby removing the battery 2 from the battery holder 4 while unlocking the hook 6.
[0048] In this embodiment, the operator can also hold the handle 64 and apply a force to the handle 64 to make it rotate, so that the handle 64 moves towards the base 41, thereby the hook 6 engages with the slot 5, and the battery 2 and the battery holder 4 are assembled.
[0049] like Figure 5 and Figure 7 As shown, in some embodiments, the handle 64 is provided with an opening 65 for holding, so that the operator can hold the handle 64 when inserting the hook 6 into the slot 5, unlocking the hook 6, and removing the battery 2.
[0050] like Figure 7 and Figure 8 As shown, in one specific embodiment, the opening 65 includes a first sub-opening 651 and a second sub-opening 652 that are connected. When the hook 6 is engaged in the slot 5, the first sub-opening 651 is located on the side of the second sub-opening 652 away from the base 41. The diameter of the first sub-opening 651 is smaller than the diameter of the second sub-opening 652, so that a stepped end face 653 is formed between the first sub-opening 651 and the second sub-opening 652. Thus, when the operator holds the handle 64, the operator's fingers can extend to the side of the stepped end face 653 away from the first sub-opening 651 and contact the stepped end face 653. In this way, when the handle 64 is pulled to move away from the base 41, the operator can apply force to the handle 64 by applying force to the stepped end face 653. When the handle 64 is moved closer to the base 41, the operator's thumb and at least one other finger can respectively contact the upper surface of the handle 64 and the stepped end face 653, so as to ensure that the operator always holds the handle 64 during the rotation of the handle 64.
[0051] Combination Figure 7 In one specific embodiment, the handheld part includes a grip bar (not shown) connected to the side of the battery 2 away from the side frame 42, so that the operator can hold the handle 64 with one hand and the grip bar with the other hand to lift the battery 2, which is in the unlocked state, upward away from the battery holder 4, making the operation simple.
[0052] like Figure 5and Figure 7 As shown, in some embodiments, the side of the battery 2 facing away from the base 41 has a groove 21. When the hook 6 is engaged with the slot 5, the handle 64 is located in the groove 21, so that at least a portion of the handle 64 can be accommodated within the groove 21, increasing the difficulty of the handle 64 being accidentally pulled up. In other embodiments, when the hook 6 is engaged with the slot 5, a space is formed between the end of the handle 64 away from the side frame 42 and the inner side of the groove 21, allowing the operator's hand to reach in. Thus, the operator can grasp the end of the handle 64 away from the side frame 42 and pull up the handle 64.
[0053] like Figure 3 and Figure 4 As shown, in some embodiments, the hook 6 further includes an elastic element (not shown), which surrounds the rotating shaft 61. When the hook 6 is engaged in the slot 5, the elastic element provides resistance to the rotation of the hook 6, thereby limiting the rotation of the hook 6 and increasing the locking force of the hook 6 in locking the battery 2. For example, the elastic element is a torsion spring. In a specific embodiment, when the hook 6 is engaged in the slot 5, the elastic element also provides a force to the handle 64 in the direction of the base 41, causing the handle 64 to tend to move closer to the base 41, thereby increasing the locking force on the battery 2.
[0054] like Figure 6 and Figure 7 As shown, in some embodiments, the battery 2 has a first interface 22, and the battery holder 4 has a second interface 43. The battery 2 is installed in the battery holder 4. When the hook 6 is engaged in the slot 5, the battery 2 is locked and securely attached to the battery holder 4. The first interface 22 and the second interface 43 are electrically connected, thereby connecting the battery 2 to the battery holder 4. When the hook 6 is disengaged from the slot 5, the battery 2 is detachable from the battery holder 4. The first interface 22 and the second interface 43 can be separated to disconnect the electrical connection between the first interface 22 and the second interface 43 when the battery 2 is removed from the battery holder 4.
[0055] like Figure 2 and Figure 3 As shown, in one specific embodiment, the battery 2 includes a first housing 23 and a second housing 24 arranged vertically. The first housing 23 is fixed to the second housing 24 by fasteners 25, which can be screws or bolts. A first interface 22 is provided on the second housing 24. The end of the battery 2 is provided on the first housing 23, and the top of the battery 2 is provided on the part of the second housing 24 away from the bottom support 41 and located on the side of the first interface 22 facing the side frame 42.
[0056] like Figure 1 and Figure 3 As shown, in some embodiments, the second interface 43 is provided with a wire connected to the underwater propulsion device 3, so as to realize the electrical connection between the battery 2 and the underwater propulsion device 3 and supply power to the underwater propulsion device 3.
[0057] like Figure 6 and Figure 7 As shown, in some embodiments, the battery holder 4 further includes a side wall 44 disposed on the base 41, and a boss 45 extending from the side of the side wall 44 toward the side frame 42. The boss 45 is used to support the top of the battery 2, and the second interface 43 is disposed on the side wall 44.
[0058] like Figure 6 and Figure 7 As shown, in one specific embodiment, the top of the battery 2 is located between the end of the battery 2 and the boss 45. The first interface 22 is located on the top of the battery 2 away from the side bracket 42, opposite to the second interface 43 provided on the side wall 44, facilitating the laying of wires to connect the first interface 22 and the second interface 43. In one specific embodiment, the side of the boss 45 facing away from the base 41 is provided with a surrounding wall 46, which forms a space to accommodate part of the top of the battery 2, thereby restricting the movement of the top of the battery 2 towards or away from the side bracket 42 and enhancing the stability of the battery 2 installation.
[0059] like Figure 1 and Figure 3 As shown, this application embodiment also provides a water-based mobile device (not shown), including a water-based carrier (not shown) and the aforementioned water-based thruster 10. The water-based thruster 10 also includes a clamp 7 connected to the body 1. The clamp 7 is connected to the water-based carrier to connect the water-based thruster 10 to the water-based carrier, so that the water-based thruster 10 can propel the water-based carrier to move on the water when it is working.
[0060] The water-based mobile device of this embodiment, by using the aforementioned water-based thruster 10, can enhance the installation stability of the battery 2 in the water-based thruster 10, which is mounted on the battery holder 4 via the hook 6, and keep the battery 2 locked on the battery holder 4.
[0061] In this embodiment, the water-based mobile device can be various vessels such as passenger ships, yachts, and fishing boats, with the corresponding water-based carrier being the hull and the water-based propulsion unit 10 being the outboard motor. Of course, the water-based mobile device can also be a sightseeing boat, sailboat, amphibious vehicle, or other vessels, and is not limited here.
[0062] like Figure 1 As shown, in some embodiments, the fuselage 1 includes a fuselage body 11 and an underwater fuselage 1 connected together. A base 41 is connected to the side of the fuselage body 11 away from the underwater fuselage 1. The fuselage body 11 can support the base 41. The battery 2 is installed on the fuselage body 11 through a battery holder 4. A clamp 7 is connected to the fuselage body 11 and is used to connect the fuselage body 11 to the water carrier.
[0063] like Figure 1As shown, in some embodiments, the water propulsion device 10 also includes a rudder 8 and a fixed base 9 connected to the side frame 42. The rudder 8 is rotatably connected to the fixed base 9 so that the rudder 8 can be folded when not in use for easy storage.
[0064] In this embodiment, the rudder stick 8 can be a rudder stick controller, and a safety switch (not shown) can be installed on the rudder stick 8. In an emergency, the user can pull out the safety switch to stop the underwater propulsion device 3 from outputting power, thereby improving safety performance. Furthermore, a display screen (not shown) can also be installed on the rudder stick 8 to display real-time navigation data such as the battery level of the battery 2 and the remaining driving time, so that the user can determine whether to replace the battery 2 based on the battery level.
[0065] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the content of this application's specification and drawings under the concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
