Description
Technical Field
[0001] This application relates to the field of medical assistive device technology, and in particular to an adaptive mechanical anti-shake module and an anti-shake spoon. Background Technology
[0002] Currently, there are two main types of tremor disorders in my country: Parkinson's disease and essential tremor. There are approximately 3 million Parkinson's disease patients in China, and this number is projected to reach 4.9 million by 2030 (compared to approximately 8.7 million globally). Essential tremor (ET), one of the most common movement disorders, has a prevalence of 0.9% in the general population; in China, the number of essential tremor patients is estimated to be over 10 million.
[0003] Patients with tremor often experience numbness in their hands and feet, tremors in their limbs, and loss of control over their hands. Eating, which is very easy for us normal people, becomes incredibly difficult for them. As people age, the number of people with tremor increases exponentially. For the elderly, eating independently is a matter of dignity, and being able to eat independently without causing trouble for their children is their greatest wish.
[0004] However, current solutions for stabilizing spoons primarily rely on smart hardware products. These spoons are equipped with microcomputers and small sensors, employing drone attitude calculation technology and providing active stabilization through a high-speed servo control system. However, these products are expensive and not yet widely used. Furthermore, these electronic products are limited by the power of their drive motors, requiring the use of lightweight plastic spoon containers, which are less hygienic than metal containers. The motor-driven structure also makes the spoons heavy and less comfortable to use; cleaning is difficult for users, and charging is required before each use. Additionally, these electronic products have a limited lifespan, resulting in higher operating costs. Utility Model Content
[0005] To address the issues of existing anti-shake spoons being bulky, complex in structure, and inconvenient to use and maintain, this application provides an adaptive mechanical anti-shake module and an anti-shake spoon.
[0006] Firstly, this application provides an adaptive mechanical image stabilization module, which adopts the following technical solution:
[0007] An adaptive mechanical image stabilization module includes:
[0008] The housing includes an upper housing and a lower housing that fit together, and the housing has a receiving cavity;
[0009] Two conical compression springs are provided and respectively installed in the upper housing and the lower housing, with the cone apexes of the two conical compression springs arranged adjacent to each other;
[0010] The mounting rod has one end extending into the receiving cavity and the other end having a slot for inserting the target anti-shake component. The mounting rod is located between the two conical compression springs.
[0011] A pin is fixed to one end of the mounting rod that extends into the accommodating cavity, and both ends of the pin protrude from the side of the mounting rod. The housing has a movable groove for the pin to swing, and the mounting rod is movably mounted on the housing via the pin.
[0012] Furthermore, the length of the movable groove is greater than the length of the pin.
[0013] Furthermore, the end of the mounting rod with the slot is made of extrudable plastic.
[0014] Furthermore, the mounting rod has a locking block elastically embedded in at least one side of the slot wall. When the target anti-shake component is fully inserted into the slot, the locking block is embedded in the groove of the target anti-shake component.
[0015] Furthermore, one end of the mounting rod extending into the accommodating cavity is located between the radial gaps of the two conical compression springs.
[0016] Furthermore, one end of the mounting rod extending into the accommodating cavity is located between the axial gaps of the two conical compression springs.
[0017] Furthermore, an extension is fixedly connected to one end of the housing opposite to the mounting rod.
[0018] Furthermore, the outer surface of the housing is provided with an anti-slip structure.
[0019] Furthermore, a sealing groove is provided on the housing, and a sealing rubber gasket is embedded in the sealing groove. The mounting rod passes through the sealing groove and extends into the receiving cavity.
[0020] Secondly, this application provides an adaptive mechanical anti-shake spoon, which includes the aforementioned adaptive mechanical anti-shake module and a spoon body. The handle of the spoon body is interference-fitted into the slot of the mounting rod, or the handle of the spoon body has a groove for locking and preventing dislodgement.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. By placing the end of the mounting rod between two conical compression springs, the axial compression deformation of the conical compression springs can suppress vertical vibration, and the radial bending deformation can suppress horizontal vibration to a certain extent. Thus, the anti-vibration module of this application not only has an effective anti-vibration effect in the vertical direction, but also has a certain anti-vibration effect in the horizontal direction. It is suitable for situations where the vertical vibration amplitude is much greater than the horizontal vibration amplitude during normal vibration, resulting in a better user experience.
[0023] 2. Due to the setting of the conical compression spring, when the two conical compression springs are compressed for vibration reduction and anti-shaking, the space occupied by them in the housing cavity is small, which makes the housing shape small and flat enough, and makes the anti-shaking module of this application simple in structure, easy to use and maintain.
[0024] 3. By making a stable and detachable connection between the mounting rod and the target anti-shake component, the target anti-shake component can be easily replaced, and non-destructive disassembly of different parts and components can be achieved, making it more widely applicable.

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0038] Reference Figure 1 and Figure 2 This application discloses an adaptive mechanical image stabilization module, which includes:
[0039] The housing 1 includes an upper housing 111 and a lower housing 121 that are interlocked, and the housing 1 has a receiving cavity 13; wherein the upper housing 111 and the lower housing 121 can be connected by snap-fit or by screw fastening.
[0040] Two conical compression springs 2 are provided and installed in the upper housing 111 and the lower housing 121 respectively, with the cone apexes of the two conical compression springs 2 being arranged adjacent to each other; specifically, mounting grooves 18 are recessed on the inner walls of the upper housing 111 and the lower housing 121, and the cone bottoms of the conical compression springs 2 are fixedly connected to the bottom wall of the mounting grooves 18.
[0041] Mounting rod 3 has one end extending into receiving cavity 13 and is flat, and the other end has a slot 31 for inserting the target anti-shake component. Mounting rod 3 is located between two conical compression springs 2.
[0042] The pin 4 is fixed to one end of the mounting rod 3 that extends into the receiving cavity 13, and both ends of the pin 4 protrude from the side of the mounting rod 3. The housing 1 is provided with a movable groove 14 for the pin 4 to swing. The mounting rod 3 is movably mounted on the housing 1 through the pin 4.
[0043] Therefore, after the target anti-shake component is installed on the mounting rod 3, for example, after the handle of the spoon container is inserted into the slot 31 of the mounting rod 3 for fixation, when using this application for eating, even if the user's hand trembles, when this tremor is transmitted to the housing 1, since the target anti-shake component is installed on the housing 1 by means of the mounting rod 3, and the mounting rod 3 is connected to the housing 1 by a locking pin in a hinge-like manner, and the two conical compression springs 2 are located on both sides of the mounting rod 3 away from the end of the target anti-shake component, the elastic force of the conical compression springs 2 will counteract the vertical influence of this tremor as much as possible, so that the mounting rod 3 always remains near the central axis of the inner cavity of the hand grip structure of the housing 1, and there will be no large range of positional movement, thereby effectively suppressing the vertical shaking of the user's hand.
[0044] Moreover, due to the setting of the conical compression spring 2, when the two conical compression springs 2 are compressed for vibration reduction and anti-shaking, the space occupied by them in the accommodating cavity 13 of the housing 1 is small, so that the housing 1 can be small and flat enough, and the anti-shaking module of this application can be simple in structure, easy to use and maintain.
[0045] Furthermore, refer to Figure 1 and Figure 2 The length of the movable groove 14 is greater than the length of the pin 4, and the width of the movable groove 14 is greater than the outer diameter of the pin 4, so that the mounting rod 3 can move in a certain horizontal direction on the housing 1. That is, after the user holds the anti-shake module of this application, the target anti-shake component can further shake in a certain amount in the horizontal direction to optimize the anti-shake effect.
[0046] Furthermore, in order to achieve the high-efficiency image stabilization effect of the image stabilization module of this application.
[0047] In one feasible embodiment, one end of the mounting rod 3 extending into the receiving cavity 13 is located between the radial gaps of the two conical compression springs 2. Therefore, even if the user experiences horizontal shaking due to vibration while holding the anti-shake module, the mounting rod 3, positioned between the two conical compression springs 2 in the horizontal direction, can suppress this shaking through the radial deformation of the conical compression springs 2. This means that the anti-shake module of this application not only has effective anti-shake effect in the vertical direction but also provides a certain degree of anti-shake effect in the horizontal direction, making it suitable for situations where the vertical shaking amplitude is much greater than the horizontal shaking amplitude during normal vibration, resulting in a better user experience.
[0048] In another feasible embodiment, one end of the mounting rod 3 extending into the receiving cavity 13 is located between the axial gaps of the two conical compression springs 2, and positioning pins inserted into the conical apex cavities of the conical compression springs 2 are fixedly attached to both sides of the mounting rod 3 near the two conical compression springs 2. Thus, good anti-shake effect can be achieved by means of the elastic deformation force of the conical compression springs 2 in both the axial and radial directions.
[0049] In order to facilitate a stable and detachable connection between the mounting rod 3 and the target anti-shake component, so as to facilitate the replacement of the target anti-shake component and achieve non-destructive disassembly of different parts and components.
[0050] In one feasible embodiment, the end of the mounting rod 3 with the slot 31 is made of a deformable plastic, such as nylon. Thus, after the handle of the target image stabilizer is interference-fitted into the slot 31 of the mounting rod 3, as... Figure 3 As shown, it can achieve the effect of preventing the target anti-shake component from detaching from the mounting rod 3 and facilitating easy installation and removal, improving the replacement efficiency of the target anti-shake component, and is applicable to different scenarios, increasing the flexibility and practicality of the anti-shake module of this application.
[0051] In another feasible embodiment, refer to Figure 4 and Figure 5 The mounting rod 3 has a locking block 32 elastically embedded in at least one side of the slot wall of the slot 31. The locking block 32 can be a cylinder with a spherical end or a sphere in its entirety. When the target anti-shake component is fully inserted into the slot 31, the locking block 32 is embedded in the groove 51 of the target anti-shake component. In this way, when the handle of the target anti-shake component is fully inserted into the slot 31 of the mounting plate, the locking hole block elastically embedded in the slot wall of the slot 31 springs into the groove 51 on the handle of the target anti-shake component, which can also lock the target anti-shake component in the slot 31 to a certain extent. When it is necessary to remove the target anti-shake component, only a large force needs to be applied to make the locking block 32 disengage from the groove 51 on the handle of the target anti-shake component, and the target anti-shake component can be removed.
[0052] In order to improve the stability of users holding this application, refer to Figure 1 and Figure 2 On the one hand, an extension 15 is fixedly connected to the end of the housing 1 away from the mounting rod 3; on the other hand, an anti-slip structure is provided on the outer surface of the housing 1. The anti-slip structure can be an anti-slip protrusion, an anti-slip groove, or an anti-slip rubber, such as a silicone anti-slip layer. Similarly, anti-slip protrusions, anti-slip grooves, etc. can be further provided on the silicone anti-slip layer.
[0053] Furthermore, for the convenience of cleaning in this application, refer to Figure 2 and Figure 4The housing 1 has a sealing groove 16, and a sealing rubber gasket 17 is embedded in the sealing groove 16. The sealing rubber gasket 17 is made of silicone rubber. The mounting rod 3 passes through the sealing groove 16 and extends into the receiving cavity 13. Specifically, sealing grooves 16 are provided at corresponding positions on the upper housing 111 and the lower housing 121. The sealing rubber gasket 17 is embedded in the sealing groove 16. The sealing rubber gasket 17 can be directly fixed to the outer periphery of the mounting rod 3, or it can be separately embedded in the sealing groove 16.
[0054] In this way, by setting the sealing rubber gasket 17, the inlet on the housing 1 into which the mounting rod 3 extends can be sealed and waterproofed, reducing the cleaning frequency of the anti-shake module of this application and reducing the possibility of foreign objects contaminating the relevant components in the accommodating cavity 13 of the housing 1; at the same time, the sealing rubber gasket 17 made of silicone rubber has good flexibility and elasticity, which will not cause significant interference to the anti-shake effect of the mounting rod 3 on the housing 1, and can also provide a certain reset ability after the mounting rod 3 shakes, which can also ensure the anti-shake effect of the anti-shake module of this application.
[0055] This application also discloses an adaptive mechanical anti-shake spoon, which adopts the following technical solution based on the above-mentioned adaptive mechanical anti-shake module:
[0056] An adaptive mechanical anti-shake spoon, as shown in the reference Figure 3 , Figure 4 and Figure 5 The invention includes the aforementioned adaptive mechanical anti-shake module, and also includes a spoon body 5, wherein the handle of the spoon body 5 is interference-fitted into the slot 31 of the mounting rod 3 or the handle of the spoon body 5 has a groove 51 for locking and preventing dislodgement.
[0057] In this way, by means of the interference fit between the spoon handle of the spoon body 5 and the mounting rod 3, and the locking of the locking block 32 when it is embedded in the groove 51, the spoon body 5 and the anti-shake module can be easily disassembled, which is applicable to different spoon bodies 5.
[0058] In use, the two conical compression springs 2 enable the spoon body 5, which is indirectly held by the user, to have good vertical anti-shake effect and a certain degree of horizontal anti-shake effect; at the same time, the size of the shell 1 can be reduced to a minimum, resulting in a better grip and easier maintenance.
[0059] The implementation principle of an adaptive mechanical anti-shake module in this application embodiment is as follows:
[0060] After the target anti-shake component is installed onto the mounting rod 3, for example, after the handle of the spoon container is inserted into the slot 31 of the mounting rod 3 for fixation, when using this application for eating, even if the user's hand trembles, when this tremor is transmitted to the housing 1, because the target anti-shake component is mounted on the housing 1 by means of the mounting rod 3, and the mounting rod 3 is formed on the housing 1 by a locking pin in a hinge-like connection, and the two conical compression springs 2 are located on both sides of the mounting rod 3 away from the end of the target anti-shake component, the elastic force of the conical compression springs 2 will counteract the effect of this tremor in the vertical direction as much as possible, so that the mounting rod 3 always remains stable. Near the central axis of the inner cavity of the grip structure of the housing 1, there will be no large-scale positional movement, thus effectively suppressing the vertical shaking of the user's hand. At the same time, the radial deformation of the conical compression spring 2 will also suppress the horizontal shaking of this vibration. Therefore, the anti-shake module of this application not only has an effective anti-shake effect in the vertical direction, but also has a certain anti-shake effect in the horizontal direction. It is suitable for situations where the vertical shaking amplitude is much greater than the horizontal shaking amplitude during normal vibration, resulting in a better user experience.
[0061] Moreover, due to the setting of the conical compression spring 2, when the two conical compression springs 2 are compressed for vibration reduction and anti-shaking, the space occupied by them in the accommodating cavity 13 of the housing 1 is small, so that the housing 1 can be small and flat enough, and the anti-shaking module of this application can be simple in structure, easy to use and maintain.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
