Description
Technical Field
The invention belongs to the technical field of bicycle parts, and relates to a linkage triggering type self-lifting bicycle heel brace.
Background
The bicycle is an environment-friendly two-wheeled vehicle taking pedal as power. As a traditional human walking tool, the utility model has long history and wide public foundation. Due to the fact that the utility model accords with the current healthy and environment-friendly life theory and helps to solve the problems of traffic jam and 'last kilometer' of user travel, a bicycle becomes a favorite traffic and body-building tool for residents in all countries of the world, particularly developed countries. In China, the shared bicycle is raised, so that the bicycle returns to the field of vision of people, and the use amount of the bicycle is greatly improved. But sharing a bicycle brings convenience to us and also brings difficulty to management of the city. Because people pay little attention to parking of shared bicycles, people often park at will in order to save time. In places with dense traffic such as subway openings, bus stops, shopping malls and the like, people often can incline to the ground when sharing bicycles with unordered parking. People can park the bicycle more conveniently and efficiently, and the problem of disorder parking can be improved to a certain extent. There are two common parking modes of the bicycle on the market, namely, a foot support at one side of a rear wheel supports the whole bicycle body. One is to lean the vehicle against another object while parked. However, we can find that the bicycle heel brace that is running is in a descending state from time to time, on the one hand, the heel brace is damaged due to the fact that the heel brace is in an outdoor use environment which is easy to corrode and the use mode that the long-term stress points are too concentrated, on the other hand, the modern society life rhythm is quickened, and a plurality of office workers are in a state of being in a hurry all the day, so that the heel brace cannot be forgotten to be lifted to directly ride when the bicycle is used. This seems to be a small use link, but brings a lot of inconveniences, which may bring destructive damage to the heel brace structure and increase the potential safety hazard in the driving process. The bicycle without the foot support is mostly a sport bicycle but is not suitable for most bicycles, such as a common household bicycle and a sharing bicycle, and the bicycle without the foot support is very inconvenient to park. Similar patents have not been presented in the market at present, but only the improvement of the heel brace structure from the aspect of adjustability and fixability, such as patent numbers: 201721388456.5 entitled "a bicycle stand" discloses a stand for parking on uneven road surfaces. Through being equipped with first inclined plane in ring side, be equipped with the second inclined plane in the one end side of guide ring, the boss sets up in the spout, when stopping to the vaulting pole from horizontal direction rotation degree to vertical direction, first inclined plane extrusion second inclined plane for the friction ring compresses tightly the back rim plate. However, the support needs to be fixed manually during parking, which is complicated and has less applicable scenes.
Disclosure of Invention
The invention aims to provide a linkage triggering type self-lifting bicycle heel brace. The mechanical structure is added in the foot support, so that the foot support can be automatically lifted when the bicycle starts to run forwards, and the foot support can be beaten by slightly pushing the bicycle backwards when the bicycle is parked.
The invention relates to a linkage triggering type self-lifting bicycle heel brace which comprises a driving part, a transmission part and a heel brace part.
The driving part consists of a pawl shaft disc coaxially and fixedly connected with the wheel and a pawl disc connected with the pawl shaft disc; the pawl disc is provided with four pawls which are fixed by four fixed shafts and are divided into left and right directions, the pawls on the same side have the same direction, and torsion springs are arranged in the pawls and are used for ejecting the pawls;
The transmission part is divided into a heel brace lifting transmission part and a heel brace falling transmission part; the foot support lifting transmission part consists of a forward driving disc, a plurality of tooth grooves are formed in the driving disc, and the driving disc and the pawl shaft disc can rotate relatively in a matched manner through a bearing; the foot support falling transmission part consists of a backward driving disc, a plurality of tooth grooves are formed in the driving disc, and the driving disc and the pawl shaft disc can rotate relatively through the cooperation of a bearing;
The heel brace part consists of two heel brace discs, a heel brace crank, a heel brace rod, a fastener, a clip, a fastener spring and a heel brace spring; two heel brace discs are fixed on two sides of the frame and used for fixing the components, and a baffle plate is arranged for limiting the limit position of the heel brace when the heel brace falls down; the foot rest crank and the foot rest rod are assembled into a foot rest, and the foot rest is assembled on a driving rod on a rotatable and advancing driving disc of the foot rest disc for transmission; the fastener and the heel brace disk are assembled in a sliding fit manner and can slide relatively, the tail end of the fastener is in contact transmission with the cam of the backward driving disk, the heel brace rod is hooked by the fastener when the heel brace rod is lifted, and the heel brace rod falls when the fastener is separated from the heel brace rod; the clip is assembled on the heel brace disc and can rotate, and is used for clamping the fastener when the bicycle back fastener stretches out; the fastener spring is used for returning the fastener; the foot support spring gives the torque for the foot support to fall down, so that the foot support can fall down more reliably; the clip spring gives torque to the clip so that the clip can be effectively clamped in the groove of the fastener;
The linkage triggering type self-lifting bicycle heel brace is divided into two states of heel brace lifting and heel brace falling. The foot support is lifted up: when a bicycle advances, a pawl shaft disc fixedly connected with wheels is the same as the rotation direction of the wheels, at the moment, a pawl on the pawl disc, which is close to an advancing driving disc, enters a clamping groove to drive the advancing driving disc to move, a driving rod on the advancing driving disc pushes a foot support crank to transfer the movement to a foot support rod, so that the foot support rod rises, when the foot support rod moves to a preset position, the foot support rod impacts a clamp contact to give a torque to a clamp, so that the clamp leaves the clamping groove, and a fastener rapidly approaches the foot support disc under the action of the tension of a clamp spring to clamp the foot support rod, so that the foot support rod cannot fall down, and the function of lifting the foot support when the bicycle advances is realized. The foot support is in a falling state: when the bicycle is retreated, the pawl shaft disc fixedly connected with the wheels is the same as the rotation direction of the wheels, at the moment, the pawl on the pawl disc, which is close to the retreating driving disc, enters the clamping groove to drive the retreating driving disc to move, the cam on the retreating driving disc pushes the fastener to be away from the heel brace disc, when the topmost end of the inclined surface is contacted with the fastener, the fastener enters the inclined surface of the clamping groove of the fastener, at the moment, the fastener gives a lateral force to the fastener, then moves to the farthest end, the fastener completely enters the clamping groove, the fastener completely breaks away from the heel brace rod at the moment, the heel brace rod falls under the action of the heel brace spring until the limit position, which is contacted with the baffle plate on the heel brace crank, is moved, and therefore the function of falling the heel brace when the bicycle is retreated is realized.
According to the invention, the function of automatically lifting the foot support is realized through the pawl transmission structure between the foot support and the wheel, when the wheel rotates forwards, the foot support of the bicycle automatically rises, and when the wheel rotates backwards, the foot support of the bicycle automatically falls. By applying the foot support structure, a user can ride more conveniently, and the riding experience is better achieved. Effectively avoids the inconvenience and potential safety hazards in the running process caused by a series of reasons such as rust of the heel brace, sliding wire and the like or forgetting to lift the heel brace due to rushing, carelessness and the like. The biggest innovation of the structure is that the original bicycle structure is not required to be changed, an electric device is not required, and the automatic lifting of the bicycle heel support can be realized only through a full-mechanical transmission structure. The bicycle is simple and easy to use in structure, convenient to maintain, applicable to various bicycles, and good in innovation and practical value, and implements a high-quality sports concept.
The beneficial effects of the invention are that
(1) The problems that the foot support is forgotten to be lifted due to a series of reasons such as rust and sliding wire of the foot support or due to reasons such as time expelling and carelessness are effectively avoided, and inconvenience and potential safety hazards possibly exist in the running process are avoided.
(2) The whole linkage triggering type self-lifting bicycle heel brace is an independent whole, the original bicycle type is not required to be modified, and the device can be used only by being singly clamped on a bicycle.
(3) The simple ratchet wheel transmission principle is adopted, the structure is simple, and the maintenance is convenient.
(4) The use method is simple and convenient, and from the life details, the high-quality life concept is implemented, so that the daily riding life of people is more comfortable and safe.
