Description

Technical Field

[0001] This utility model relates to the field of electric bicycle accessories technology, and in particular to a damped basket opening limiter and a basket. Background Technology

[0002] Electric bicycles, including electric two-wheelers and electric tricycles, have become a widely used means of short-distance travel due to their convenience and environmental friendliness. To facilitate carrying personal belongings, electric bicycles are usually equipped with a basket at the front. Currently, most baskets on the market have lids that are hinged to the basket body using simple hinges or pivots.

[0003] However, this traditional connection method has many drawbacks. First, during riding, especially on bumpy roads, the basket lid is prone to opening and closing on its own due to vibration, which not only produces unpleasant noise but may also damage the basket's structure with prolonged impact. Second, the operation of opening or closing the basket lid is abrupt, lacking smooth damping and cushioning, resulting in a poor user experience. More importantly, this structure cannot stably keep the basket lid at any angle between fully open and fully closed. For example, users cannot keep the lid half-open to easily access small items, which causes considerable inconvenience in practical use.

[0004] Therefore, there is an urgent need in this field for a damped basket opening limiter and a basket that can provide good damping for the opening and closing of the basket lid and can stop the basket lid at any opening position, so as to fundamentally solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a damped basket opening limiter and a basket to solve the problems existing in the prior art. It can provide good damping for the opening and closing of the basket cover and can keep the basket cover at any opening position.

[0006] To achieve the above objectives, this utility model provides the following solution:

[0007] This utility model provides a damped basket opening limiter, including: a clamping mechanism and a resistance wheel;

[0008] The clamping mechanism includes a mounting part, an elastic element, and a top block. The top block is movably mounted on the mounting part along a straight line. One end of the elastic element is connected to the mounting part, and the other end is connected to the top block.

[0009] The outer circumferential surface of the resistance wheel is provided with multiple circumferentially distributed pits;

[0010] The end of the top block away from the elastic element is continuously pressed against the outer peripheral surface of the resistance wheel under the action of the elastic element, and the top block is configured to align with the axis of the resistance wheel to provide radial pressure.

[0011] Furthermore, the mounting portion is provided with a movable cavity, one end of which has an opening; the elastic element is housed within the movable cavity, one end of which is connected to the mounting portion, and the other end of which is connected to the top block;

[0012] The top block is configured to slide linearly within the movable cavity, with one end of the top block extending through the opening and abutting against the outer peripheral surface of the resistance wheel.

[0013] Furthermore, it also includes adjusting bolts;

[0014] The mounting part is provided with a threaded hole communicating with the movable cavity. The adjusting bolt is threaded into the threaded hole, and its screw-in end is connected to the end of the elastic element away from the top block.

[0015] Furthermore, the elastic element is a helical spring, and the screw-in end of the adjusting bolt is provided with a spring seat for positioning and receiving one end of the helical spring.

[0016] Furthermore, the resistance wheel has a wavy outer peripheral surface, and the recess is the trough of the wavy outer peripheral surface.

[0017] Furthermore, the end of the top block that contacts the outer circumferential surface of the resistance wheel is configured as a hemispherical structure.

[0018] Furthermore, the mounting part also includes a mounting bracket for securing it to the basket.

[0019] This utility model also provides a bicycle basket, including a basket body, a basket cover, and the aforementioned damping type bicycle basket opening limiter;

[0020] The basket body and the basket cover are hinged together by a connecting shaft;

[0021] The resistance wheel is fixedly sleeved on the connecting shaft;

[0022] The connecting shaft is fixedly connected to the basket cover, and the tightening mechanism is fixedly connected to the basket body; or, the connecting shaft is fixedly connected to the basket body, and the tightening mechanism is fixedly connected to the basket cover.

[0023] Furthermore, the resistance wheel is fixed to the connecting shaft by a key connection, spline connection, or interference fit.

[0024] The present invention achieves the following technical advantages over the prior art:

[0025] Applying a damped basket opening limiter to the basket allows the top block to press against the outer circumference of the resistance wheel under the continuous action of the elastic element. When the top block falls into the recess, a stable mechanical equilibrium point is formed. This allows the basket lid to stably stop at multiple predetermined positions (i.e., the angles corresponding to each recess) during opening or closing, achieving "stepless stopping" or "multi-angle holding" functions, greatly facilitating user use of the basket in different scenarios. When rotating the basket lid, the top block needs to overcome the pressure of the elastic element, sliding from one recess to the next. This process generates periodic resistance changes, providing users with a smooth damping buffer effect and a clear tactile feedback, effectively improving the product's handling and premium feel. The continuous elastic pressure between the top block and the outer circumference of the resistance wheel eliminates the gap between the basket lid and the vehicle body. Therefore, when riding a vehicle on bumpy terrain, this limiter can effectively lock the basket cover, preventing it from swinging or slapping freely due to vibration, thereby significantly reducing the resulting noise, reducing wear on structural components, and improving the reliability and durability of the product.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] The purpose of this utility model is to provide a damped basket opening limiter to solve the problems existing in the prior art. It can provide good damping for the opening and closing of the basket cover and can stop the basket cover at any opening position.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] This utility model provides a damped basket opening limiter, such as Figure 1 As shown, it includes a clamping mechanism and a resistance wheel 4; the clamping mechanism includes a mounting part 1, an elastic element 2 and a top block 3, wherein the top block 3 is movably mounted on the mounting part 1 along a straight line; one end of the elastic element 2 is connected to the mounting part 1 and the other end is connected to the top block 3; the outer peripheral surface of the resistance wheel 4 is provided with a plurality of circumferentially distributed pits; the end of the top block 3 away from the elastic element 2 is continuously pressed against the outer peripheral surface of the resistance wheel 4 under the action of the elastic element 2, and the top block 3 is configured to align with the axis of the resistance wheel 4 to provide radial pressure.

[0035] In one implementation, the top block 3 can move linearly on the mounting part 1 by setting a limiting structure such as a slide rail or a sliding cavity.

[0036] In one embodiment, the elastic element 2 can be a coil spring, disc spring, elastic rubber column, or other element that can apply elastic force.

[0037] In use, the damping-type basket opening limiter is applied to the basket. Because the top block 3 is pressed against the outer circumference of the resistance wheel 4 under the continuous action of the elastic element 2, a stable mechanical equilibrium point is formed when the top block 3 falls into the recess. This allows the basket cover 7 to stably stop at multiple predetermined positions (i.e., the angles corresponding to each recess) during opening or closing, achieving the functions of "stepless stopping" or "multi-angle holding," greatly facilitating the use of the basket in different scenarios. When rotating the basket cover 7, the top block 3 needs to overcome the pressure of the elastic element 2, sliding from one recess to the next. This process generates periodic resistance changes, providing users with a smooth damping buffer effect and a clear tactile feedback, effectively improving the product's handling and premium feel. The continuous elastic pressing between the top block 3 and the outer circumference of the resistance wheel 4 eliminates the gap between the basket cover 7 and the basket body 8. Therefore, when the vehicle is riding on bumps, the limiter can effectively lock the basket cover 7, preventing it from swinging or slapping freely due to vibration, thereby significantly reducing the noise generated and reducing the wear of structural components, and improving the reliability and durability of the product.

[0038] As an example of an implementable approach, such as Figure 1As shown, the mounting part 1 has a movable cavity 11, one end of which has an opening. An elastic element 2 is housed within the movable cavity 11, with one end connected to the mounting part 1 and the other end connected to a top block 3. The top block 3 is configured to slide linearly within the movable cavity 11, with the end of the top block 3 away from the elastic element 2 extending through the opening and abutting against the outer circumferential surface of the resistance wheel 4. The movable cavity 11 provides precise linear motion guidance for the top block 3, ensuring that its contact point with the resistance wheel 4 remains stable, thereby making the damping force change smoother and more reliable.

[0039] As an example of an implementable approach, such as Figure 1 As shown, it also includes an adjusting bolt 5; the mounting part 1 is provided with a threaded hole communicating with the movable cavity 11, the adjusting bolt 5 is threaded into the threaded hole, and the screwed-in end is connected to the end of the elastic element 2 away from the top block 3. By rotating the adjusting bolt 5, the pre-compression amount of the elastic element 2 can be changed, thereby realizing stepless adjustment of the pre-tightening force of the top block 3, allowing the user to flexibly adjust the damping size according to actual needs.

[0040] As an example of an implementable approach, such as Figure 1 As shown, the elastic element 2 is a helical spring. A spring seat is provided at the screw-in end of the adjusting bolt 5 for positioning and receiving one end of the helical spring, and a corresponding spring seat is also provided on the top block 3. As a standard part, the helical spring has stable performance and low cost; the design of the spring seat can prevent the spring end from slipping, ensuring the stability and reliability of the preload transmission.

[0041] As an example of an implementable approach, such as Figure 1 As shown, the resistance wheel 4 has a wavy outer circumference, and the aforementioned pit is the trough of the wavy outer circumference. The crest and trough structure of the wavy outer circumference causes the top block 3 to periodically fall into the trough or cross the crest during the rotation of the basket cover 7, thereby producing a clear sense of segmentation and a predictable stopping position.

[0042] As an example of an implementable approach, such as Figure 1 As shown, the end of the top block 3 that contacts the outer circumference of the resistance wheel 4 is configured as a hemispherical structure. The hemispherical structure provides point contact, which effectively reduces the frictional resistance when the top block 3 and the resistance wheel 4 move relative to each other, making the operation smoother and reducing wear on the contact surface.

[0043] As an example of an implementable approach, such as Figure 3 As shown, the mounting part 1 also includes a mounting bracket 9 for fixing it to the basket. The mounting bracket 9 allows the mounting part 1 to be detachably connected to the basket body, improving assembly efficiency and facilitating non-destructive upgrades to ordinary baskets.

[0044] This utility model also provides a bicycle basket, such as Figures 2 to 3As shown, the system includes a basket body 8, a basket cover 7, and the aforementioned damping basket opening limiter. The basket body 8 and basket cover 7 are hinged together via a connecting shaft 6. A resistance wheel 4 is fixedly mounted on the connecting shaft 6. One connection method is that the connecting shaft 6 is fixedly connected to the basket cover 7, and the clamping mechanism is fixedly connected to the basket body 8. Another connection method is that the connecting shaft 6 is fixedly connected to the basket body 8, while the clamping mechanism is fixedly connected to the basket cover 7. Both connection methods provide controllable damping and a stopping function for the opening and closing of the basket cover 7.

[0045] As an example of an implementable solution, the resistance wheel 4 can be fixed to the connecting shaft 6 via a keyed connection, spline connection, or interference fit. These connection methods ensure no relative rotation between the resistance wheel 4 and the connecting shaft 6, guaranteeing reliable power transmission and thus ensuring consistency between the damping effect and the angle-keeping function.

[0046] Any adaptive changes made according to actual needs are within the protection scope of this utility model.

[0047] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.

Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope.
