Description

Bicycle bell

Technical Field

The embodiment of the disclosure relates to the technical field of vehicle positioning, in particular to a positionable bell.

Background

Some bells in the prior art can be directly installed on traffic vehicles such as bicycles, electric bicycles, scooters, balance cars and the like, but the function is single, and only the bells can be stirred to warn passers-by. Some prior art have also improved new functions designed by this, such as additional high cost positioning devices like GPS or beidou positioning systems mounted on the bell, to achieve positioning of the vehicle. However, these positioning schemes are costly, and in addition, the maintenance costs are high, especially in terms of power endurance.

Disclosure of Invention

In view of the foregoing technical background, there is a need for improved positioning schemes for vehicles such as bicycles, electric bicycles, scooters, balance cars, etc., to reduce the cost of the positioning schemes and/or reduce maintenance costs and/or improve convenience of use, such as being able to independently navigate in terms of electricity for a long period of time.

To this end, one non-limiting embodiment of the present disclosure provides a bell that may include a bell body that may include a base attachable to a vehicle; a striking part mounted on the bell body and performing a striking action in response to a user's hand operation; a sound part mounted on the bell body and generating a bell sound in response to the striking motion; a solar panel at least partially exposed outside the bell body; a processor coupled to the solar panel; and a communication circuit coupled to the processor and having an antenna for transmitting wireless signals to an electronic device for locating the bell by the electronic device.

The bell can be applied to vehicles such as bicycles, electric bicycles, scooters, balance cars and the like, and thus, the positioning of the vehicles can be indirectly realized through the positioning of the bell. The position information of the vehicle bell may be uploaded indirectly to a server of the positioning system by means of a first electronic device (e.g. a mobile phone), so that the user of the vehicle or vehicle can obtain the position information of the vehicle bell or vehicle in the server by means of his second electronic device (e.g. a mobile phone), thereby finding the vehicle bell and/or the vehicle in which the vehicle bell is installed. The first electronic device herein mainly refers to electronic devices of other people than the user, and particularly refers to electronic devices of other people close to the bell, such as a mobile phone. The greatest advantage of the positioning system is therefore that the positioning of the bell and/or the vehicle can be achieved indirectly by means of the electronics of other people, i.e. not just the user himself, so that it is not necessary to install on the vehicle or bell a costly active positioning-related absolute position device like a GPS/beidou system, etc., thus significantly reducing the costs of the positioning solution.

Optionally, the bell may further comprise a housing mechanically coupled to the base; the sound component and the solar panel are each at least partially mounted to an exterior of the housing; the processor and the communication circuit are both mounted to the interior of the housing.

Optionally, the housing has a top and a peripheral side, the top and the peripheral side together defining at least one receiving cavity; the sound component is elastically mounted on the outer surface of the peripheral side part; the solar panel is fixedly mounted on the outer surface of the top.

Optionally, the outer surface of the peripheral side portion comprises a first outer surface having a first average radius of curvature and a second outer surface having a second average radius of curvature greater than the first average radius of curvature; the sound component is elastically mounted on the first outer surface.

Optionally, first and second posts extend on the first outer surface at intervals; a first groove aligned with the first post and a second groove aligned with the second post are provided on an inner side surface of the sound component at intervals.

Optionally, the first post and the first groove are connected by a first elastic member, a first end of the first elastic member is fixed to the first post, and a second end of the first elastic member is fixed to the first groove; the second post and the second slot are connected by a second elastic member, a first end of the second elastic member is fixed to the second post, and a second end of the second elastic member is fixed to the second slot.

Optionally, a third post between the first post and the second post also extends on the first outer surface; a third groove between the first groove and the second groove and aligned with the third post is also provided on the inside surface of the sound component; the third post and the third groove are connected by a third elastic member, a first end of the third elastic member is fixed to the third post, and a second end of the third elastic member is fixed to the third groove.

Optionally, the tapping member is pivotally mounted to the fixed base.

Optionally, the bell further comprises a buzzer coupled to the processor;

optionally, the antenna is further configured to receive a second wireless signal that can be transmitted by a second electronic device, and the processor is configured to control the buzzer to generate sound for assisting a user in locating the bell according to the second wireless signal.

Optionally, the sound component is elastically mounted on the first outer surface by a spring, a first end of the spring is fixedly connected to the sound component, and a second end of the spring is connected to the first outer surface.

Another non-limiting embodiment of the present disclosure also provides a locating bell that may include a bell housing that may include a top and a peripheral side that together define at least one receiving cavity; a stationary base mechanically coupled to the bell housing for fixedly connecting the bell to a vehicle; a striking member pivotally mounted on the fixed base; a first sound member elastically mounted on an outer surface of the peripheral side portion of the bell housing; a solar panel fixedly mounted to an outer surface of the top of the bell housing; a controller, an energy storage component, a communication component, and a second sound component mounted within the at least one receiving cavity; wherein the knocking part is used for responding to the hand operation of a user to execute knocking actions; wherein the first sound component is for producing a first sound in response to the tapping action; wherein the energy storage component is coupled with the solar panel and stores electrical energy converted by the solar panel; wherein the communication component is for periodically transmitting a first wireless signal receivable by a first electronic device, the first electronic device locating the bell in accordance with the first wireless signal; wherein the communication component is further configured to receive a second wireless signal that is transmittable by a second electronic device, the controller being configured to control the second sound component to generate a second sound for assisting a user in locating the bell in accordance with the second wireless signal.

The bell may be applied to vehicles such as bicycles, electric bicycles, scooters, balance cars, and the like, and when the bell is installed in the vehicle, the bell may be used to locate the vehicle. This allows the positioning of the vehicle indirectly through the positioning of the bell. The position information of the bell may be uploaded indirectly to a corresponding server by means of a first electronic device (e.g. a mobile phone) so that the user of the vehicle or bell may obtain the position information of the bell or vehicle in the server by means of his second electronic device (e.g. a mobile phone) in order to find the bell and/or the vehicle in which the bell is installed. The first electronic device herein mainly refers to electronic devices of other people than the user, and particularly refers to electronic devices of other people close to the bell, such as a mobile phone. Therefore, the bell has the greatest advantage that the bell and/or the vehicle is indirectly positioned by means of the electronic equipment of other people, so that the vehicle can be timely retrieved through the positioning of the bell after being lost. Thus, there is no need to install a GPS-like active positioning tool on the vehicle or bell, thus significantly reducing the cost of the positioning solution. In addition, the solar panel is also arranged on the bicycle bell, so that the problem of autonomous endurance of electric power components in the bicycle bell can be conveniently solved.

Detailed Description

In order that the above-recited objects, features and advantages of the present disclosure will become more readily apparent, a more particular description of specific embodiments/examples thereof will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. The present disclosure may be embodied in many other alternate forms and modifications may be made by those skilled in the art to achieve the same or similar functional results without departing from the spirit of the disclosure, and it is therefore intended that the present disclosure and in particular the claims hereof be limited to non-limiting embodiments of the following disclosure.

In the description of the present disclosure, it should be understood that, if there are terms such as "center", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", "diagonal", etc., the positional relationship indicated by these terms may be understood based on the positional relationship or positional relationship shown in the drawings, for convenience of description and simplification of the description only, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present disclosure.

Furthermore, the terms "first," "second," or the like, if any, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present disclosure, the terms "plurality," "plurality," and the like, if any, mean at least two, e.g., two, three, etc., unless specifically defined otherwise.

Furthermore, unless specifically stated and limited otherwise, references to "coupled," "mounted," "connected," "secured," "mated," "disposed," and "positioned" in this disclosure should be interpreted broadly in connection with the inventive concepts of the present disclosure, as at least direct, indirect, fixed, movable, etc., and as an example "connected," as both direct and indirect, e.g., through a third party element, as well as both fixed and movable, e.g., hinged, etc. For example, "fixed" is in turn understood to mean at least both non-detachably fixed and detachably fixed.

Furthermore, as used in connection with the present disclosure, the term "coupled" may refer to two or more elements in physical or electrical or communication contact/connection with each other, or may refer to two or more elements in operation or action with each other.

In this disclosure, unless expressly stated or limited otherwise, the meaning of a "first feature being on or off a second feature" and the like, if any, may mean that the first feature is in direct contact with the second feature, or that the first and second features are in indirect contact via an intervening medium. Also, a first feature being "above," "over" and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply that the level of the first feature is higher than the level of the second feature. The first feature being "under", "below" and "beneath" the second feature may be the first feature being directly under or obliquely below the second feature, or simply indicating that the level of the first feature is less than the level of the second feature.

In addition, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and the like are used in this disclosure for descriptive purposes only and do not represent the only embodiment.

Referring to fig. 1, there is shown a bell location system 1000 that may be physically and/or geographically located using wireless communication systems and techniques in accordance with an embodiment of the present disclosure, the location system 1000 may include a bell 10, at least one first electronic device 10a, a server 10c, and a second electronic device 10e. The positioning system 1000 is therefore mainly used for finding vehicles such as bicycles, electric bicycles, scooters, balance cars, etc. which are carelessly lost or temporarily lost by the user, and which can be equipped with the bell 10 in the positioning system, by means of which bell 10 and/or the bell positioning system 1000 the user can find his or her bicycle very conveniently.

In some examples, the bell 10 may include an antenna that transmits a wireless signal that may be detected with another electronic device, such as a smart mobile phone. Using the detected wireless signals (and using positioning techniques such as time of flight, received signal strength indications, triangulation, etc.), the smart mobile phone is able to determine the position of the bell 10 relative to the smart mobile phone, and also to determine the absolute position of the bell 10 using the absolute position of the smart mobile phone relative to GPS or earth, where the absolute position of the bell 10 refers to, for example, latitude and longitude position information of the bell 10 relative to earth.

In some examples, referring to fig. 2, which relates to the system components of the vehicle bell 10, the vehicle bell 10 may include a solar panel 10f, a processor 10g, an antenna 10j coupled to the processor 10g, and an audio system 10h coupled to the processor 10 g. In some examples, a wireless signal is transmitted by the antenna 10j to other devices (e.g., smart phones, tablets, etc.) that analyze the wireless signal to determine the distance, position, location, and/or orientation of the bell 10 with high accuracy. In this disclosure, locating may refer to determining one or more spatial parameters of the bell 10 or other wirelessly positionable device. Spatial parameters include parameters of an object defining aspects of distance, position, location and/or orientation of the object in absolute space or relative to another object. For example, spatial parameters may include parameters such as distance between objects, specific geographic locations (e.g., latitude and longitude coordinates), unit vectors pointing from one object to another, orientation of objects in three-dimensional space (also referred to as angular positioning or pose), and so forth.

In some examples, more broadly, the position, location, orientation, or other spatial parameter of the bell 10 may be determined by any electronic device configured to wirelessly communicate with the bell 10. Exemplary electronic devices include smart phones, tablets, laptops, wireless routers, desktop computing devices, home automation systems, and the like. The electronic devices may update a server or other database with the location of the bell 10. This may improve the ability to locate a lost bell 10 or vehicle in which the bell 10 is installed, because the user may be able to determine the location of the bell 10 by querying the server or database to find the corresponding vehicle even if the user is not within communication range of the bell 10, such as around 10 meters when the bell 10 is using bluetooth to effect location communication.

In some examples, for example, if a user leaves her vehicle, such as a bicycle, at home, the user's home desktop computer may have periodically communicated with (or otherwise received signals from) the bell 10 attached to the range of bluetooth communications, and updated the server with the location of the bell 10. The user can thus simply request the current location of the bell 10 from the server even if she is at a distance and is unable to communicate directly with the bell 10 and her smart phone. The present disclosure describes additional exemplary use cases and device details. Outside the user's home environment, other devices not associated with the user (e.g., other people's smart phones) may also communicate with the bell 10 (or otherwise receive signals from the bell 10) to update the server securely and anonymously with the position of the bell 10. This is a significant improvement over prior positioning techniques for either the bell 10 or the positioning system 1000. More specifically, for example, outside the user's home environment, there may be thousands or even millions of electronic devices (e.g., cell phones) that are able to communicate with the bell 10 and report the location of the bell 10 securely and anonymously while within communication range of the bell 10. Any of these numerous electronic devices that are sufficiently close to the bell 10 to receive signals or communicate with the bell 10 (e.g., via bluetooth) can update the server securely and anonymously with the position of the bell 10. In this way, the large number of electronic devices that can communicate with the bell 10 or receive signals from the bell 10 are generally equivalent to forming a robust multi-redundant device location relay network that can continuously (and privately) monitor and update the locations of many individual bells 10.

In some examples, the antenna 10j in the bell 10 may communicate with a nearby electronic device (e.g., 10 a) by transmitting a periodic wireless signal. The wireless communication protocol to which the antenna 10j is adapted may be a near field wireless communication protocol (e.g., ISO/IEC 14443, ISO/IEC 18092, ISO/IEC 21481), UWB protocol, bluetooth (e.g., IEEE 802.15), wiFi (e.g., IEEE 802.11), cellular protocol, and Zigbee (IEEE 802.15.4 standard) or any suitable combination of these communication protocols. Accordingly, a nearby electronic device (e.g., 10 a) may monitor the wireless communication protocols and detect a responsive communication signal within communication range (e.g., 20 meters) of those communication protocols, thereby establishing a communication connection with the bell 10.

In some examples, the antenna 10j may periodically transmit a first wireless signal that may be received by one or more first electronic devices 10a within communication range of the antenna 10j, and the first electronic device 10a may then determine the position of the bell 10 relative to the first electronic device 10a based on the first wireless signal. For example, the first wireless signal may be a UWB signal, which in this disclosure may refer to a signal transmitted over a substantial portion of the radio spectrum (e.g., having a bandwidth greater than 500MHz or greater than 20% of the center carrier frequency). Performing positioning using UWB signals may be referred to in this disclosure as "UWB positioning.

In some examples, electronic device 10a (or a device operably coupled to electronic device 10 a) responsible for receiving the signal may analyze the UWB signal or UWB signal pulses detected by electronic device 10a (e.g., through a UWB antenna carried by device 10 a) to determine a distance between electronic device 10a and bell 10 that transmitted the UWB signal pulses. Specifically, the electronic device 10a may determine a time of flight (TOF) of the UWB signal pulse and multiply the TOF by a propagation speed (e.g., speed of light) of the signal pulse to determine or estimate a distance between the bell 10 and the electronic device 10 a.

In addition, the electronic device 10a may determine TOF by calculating the difference between the time of transmission (i.e., the time of the transmitted signal) and the time of detection of the signal, also referred to as time of arrival (TOA). The transmission time may be included in the detected UWB signal pulse, sent as part of a separate transmission, or known due to a synchronization process previously performed between the electronic device 10a and the bell 10.

Using UWB signals to determine distance or location may provide a number of advantages, including improved accuracy in determining TOA and/or TOF. For example, UWB signals may have shorter wavelengths than other signals, which may reduce the time range in which signals may be detected. This reduces errors in determining TOA and TOF, resulting in a more accurate distance estimate. In other examples, it is also preferable that the antenna 10j transmit bluetooth signals using the bluetooth communication protocol.

In some examples, the first electronic device 10a may determine the position of the bell 10a relative to a particular frame of reference (e.g., earth) and generate a corresponding position report using the position of the bell 10 relative to the first electronic device 10a and the position of the first electronic device 10a itself relative to the particular frame of reference (e.g., earth), and upload the position report to the server 10c over the network 10b (e.g., 4G communication network). In particular, the electronic device 10a (e.g., a smart phone) may include or be operatively coupled to a GPS receiver configured to determine the location of the electronic device 10 a. As described above, in this disclosure, a "location" may refer to a geographic point where an electronic device is located, such as a point of the earth's surface or elsewhere, and may be specified according to a geographic coordinate system (e.g., latitude and longitude) or according to a location relative to another geographic point or point of interest. As discussed above, UWB positioning may be used to determine the position of the chime 10 relative to the electronic device 10 a. Thus, by using the GPS to determine the location of the electronic device 10a and using the UWB positioning to determine the location of the bell 10 relative to the electronic device 10a, the absolute location of the bell 10 or the location relative to the earth (e.g., including latitude and longitude information) can be determined. In other examples, the electronic device 10a may also determine its own absolute position (relative to the earth's position) by Beidou satellite positioning or base station positioning (e.g., GSM network) or the Geornass system (GLONASS) or the Galileo system (Galileo).

As another example, in some examples, the electronic devices 10a use their own location as an estimated location of the bell 10. For example, if the device 10a is capable of connecting to the bell 10 via bluetooth, the bell 10 may be assumed to be within about 30 feet of the device 10a (or another distance, depending on the parameters of the bluetooth communication). Thus, for example, the device 10a may report the location of the bell 10 as an area centered on the electronic device 10a and having a radius corresponding to the communication range of the wireless communication protocol used to communicate with the bell 10 (e.g., the communication range of the Bluetooth communication protocol is 10-100 meters). In other cases, the electronic device 10a may more accurately determine or estimate the location of the bell 10. For example, the device 10a may use time of flight (TOF), angle of arrival (AOA), time difference of arrival (TDOA) Received Signal Strength Indication (RSSI), triangulation, synthetic aperture, and/or any other suitable technique to determine the location of the bell 10 relative to the user device 10 a.

In some examples, the user of the vehicle in which the bell 10 is installed may obtain the aforementioned location report regarding the bell 10 from the server 10c (e.g., over the 4G network 10 d) using the second electronic device 10e to locate the bell 10 so that the user may move to a location proximate to that provided by the location report to find the bell 10 or the vehicle in which the bell 10 is installed. Then, when the user approaches the bell 10 or the vehicle in which the bell 10 is installed, for example, when the user comes within a wireless communication range (for example, 50 meters) of the bell 10, the antenna 10j in the bell 10 can establish communication with the user's electronic device 10e (for example, a cell phone). More specifically, the antenna 10j may receive a second wireless signal (e.g., a Bluetooth signal) transmitted by the electronic device 10e that includes primarily instructions for producing sound, such that the processor 10g in the chime 10 may control the responsive audio system 10h (e.g., a buzzer) to produce an audible audio output, such as a beep or other audible tone (e.g., a constant tone, song, etc.), for assisting the user in locating/discovering the chime 10 at that time in response to receiving the second wireless signal. It should be noted that the types of the second wireless signal and the first wireless signal may be the same or similar, for example, both are bluetooth signals.

In some examples, the aforementioned bell 10 also includes an at least partially exposed solar panel 10f for powering at least the processor 10g, the antenna 10j, and the audio system 10 h. Due to the solar panel 10f, the cruising problem of the bell 10 is guaranteed, and the user is not required to charge the bell in a tedious manner. The type of the solar panel 10f is not particularly limited, and may include several types or any suitable combination of these types such as a single-junction solar panel (made of single-crystal silicon or polycrystalline silicon, and having a conversion efficiency of generally 15% to 20%), a thin-film solar panel (made of amorphous silicon, copper indium gallium selenide, or the like, and having a conversion efficiency generally lower than that of a single-junction solar panel, but having a low manufacturing cost), a multi-junction solar panel (made of stacked photoelectric materials having different energy gaps, and having a conversion efficiency of theoretically up to 30% or more), and the like.

In some examples, referring to fig. 3, a method of locating a bell is shown, which may be referred to, for example, as bell 10 described above, which may likewise include a processor, an antenna coupled to the processor, and an audio system coupled to the processor. The relevant steps or processes of the method for locating a bell may thus be the same as or similar to the relevant functions of the bell 10 or the relevant components of the bell 10 (e.g., the processor 10g, the antenna 10j, the audio system 10 h) and the technical effects (efficiencies) achieved by the method for locating a bell may be the same as or similar to the technical effects (efficiencies) achieved by the bell 10 or the relevant components of the bell 10 (e.g., the processor 10g, the antenna 10j, the audio system 10 h). Specifically, the method may include the steps of:

Step S10: an antenna is used to periodically transmit a first wireless signal receivable by a first electronic device within a communication range of the antenna.

Step S20: the position of the bell relative to the first electronic device is determined from the first wireless signal using the first electronic device.

Step S30: the position of the bell relative to a specific reference frame (such as the earth) is determined by using the first electronic device according to the position of the bell relative to the first electronic device and the position of the first electronic device relative to the specific reference frame, and a corresponding position report is generated and uploaded to a server.

Step S40: the location report is obtained from a server using a second electronic device to locate the bell.

Step S50: a second wireless signal transmitted by a second electronic device is received using an antenna.

Step S60: the processor is used to control the audio system to produce an audible audio output, such as a beep or other audible tone (e.g., a constant tone, song, etc.), for assisting the user in locating the bell in response to receiving the second wireless signal.

In some examples, the first wireless signal may be a UWB signal, which in this disclosure may refer to a signal transmitted over a substantial portion of the radio spectrum (e.g., having a bandwidth greater than 500MHz or greater than 20% of the center carrier frequency). Performing positioning using UWB signals may be referred to in this disclosure as "UWB positioning. Referring to fig. 4, therefore, the first electronic device (e.g., electronic device 10 a) may further include the following steps in performing step S20: step S201: the time of transmission of the UWB signal is determined. Step S202: the time of receipt of the UWB signal is determined. Step S203: the difference between the time of transmission of the UWB signal and the time of receipt of the UWB signal is calculated to determine the TOF of the UWB signal. Step S204: the distance between the bell and the first electronic device is determined using the first electronic device by multiplying the propagation speed of the UWB signal with the TOF.

With continued reference to fig. 2, the bell 10 of this embodiment further includes a memory 10K coupled to the processor 10g and a program (or instructions) 10n stored in the memory 10K and executable on the aforementioned processor 10g, the processor 10g in the bell 10, when executing the program 10n, may implement relevant steps in the aforementioned exemplary methods, such as at least steps S10 and S60.

It will be appreciated by those skilled in the art that the system composition diagram of fig. 2 is merely an example of the system composition of the bell 10 and is not intended to limit the system composition of the bell 10, and may include more or less components than those shown in fig. 2, or may combine certain components, or different components, such as may also include input-output devices, network access devices, etc.

Further, the memory 61 may also include both an internal memory unit and an external memory device of the robot 6. The memory 10K may be used to store an operating system, application programs or instructions, boot loader (BootLoader), data, and other program code, among others. The memory 10K may also be used to temporarily store data that has been output or is to be output.

It will be apparent to those skilled in the art that, for convenience and brevity of description, the program 10n executable by the processor 10g may constitute each software functional unit or module, and in practical application, the above-mentioned functions may be distributed as needed to be completed by different functional units or modules, i.e. the internal structure of the apparatus is divided into different functional units or modules to complete all or part of the functions described above.
