Detailed Description

Furthermore, to any single feature described or implicit in an embodiment herein or shown or implicit in any single feature or features shown or implicit in the drawings, the invention still allows any combination or permutation to be continued between the features (or their equivalents) without any technical barriers, and thus further embodiments according to the invention should be considered within the scope of this disclosure. In addition, for the sake of brevity, identical or similar components and features may be indicated in the same drawing only in one or several places, and general matters already known to those skilled in the art are not described in detail herein.

Referring to fig. 1, a block diagram of an embodiment of the device for detecting the operating parameters of the running wheel according to the present invention is schematically shown, and the design idea and the basic configuration of the present invention can be roughly explained by this embodiment.

Specifically, the running wheel operating parameter detecting device 100 may include two components, namely, the magnetic component 11 and the detection module 12 shown in fig. 1, for exemplary illustration only. The magnetic member 11 may be mounted on a running wheel of various types of vehicles (e.g., fuel-powered vehicles, electric-only vehicles, hybrid vehicles, electric bicycles, airport ferry vehicles, etc.), aircraft (e.g., unmanned vehicles, manned vehicles, etc.), etc., to provide an operating magnetic field and a change in the magnetic field so that the information on the operating parameters of the running wheel can be determined in response to the change in the magnetic field. For example, a specific example is given in the following fig. 2, in which the magnetic member 11 is fitted around the mounting shaft 2 of the running wheel 1, since the magnetic field distribution formed by the magnetic member 11 is affected when the running wheel 1 performs a rotational motion, i.e. a magnetic field change is caused. The current operating state of the running wheel 1 can be correspondingly reflected on the basis of such a magnetic field change, which can be detected by means of a detection module 12, which will be described below.

As shown in fig. 1, the detection module 12 is associated with the magnetic component 11 and is arranged to detect the above-mentioned magnetic field variations and to generate accordingly an operating parameter signal S of the running wheel based on such magnetic field variations, which may comprise at least an angle signal S1 of the running wheel, a speed signal S2 of the running wheel, for example, or may also comprise further possible operating parameter signals such as an acceleration signal, a speed rate signal, etc. of the running wheel. By way of illustration, the detection module 12 may obtain the angle signal S1 of the running wheel, the speed signal S2 of the running wheel, and/or other operating parameter signals by detecting parameters such as the magnitude and the change rate of the magnetic flux in the current magnetic field provided by the magnetic component 11, and may also obtain more possible operating parameter signals such as the acceleration signal and the angular acceleration signal of the running wheel by performing calculation processing on the angle signal S1 and the speed signal S2, respectively, so as to better meet different application requirements. The acquisition and processing conditions of specific operation parameter signals can be flexibly selected, set or adjusted according to actual application occasions.

For the magnetic element 11, any suitable element may be used, such as a permanent magnetic element, an electromagnetic element, etc., which is capable of providing a magnetic field during operation. Referring to fig. 3, the magnetic part 11 can optionally be configured in a ring shape so that it can be very conveniently fitted over the mounting shaft 2 of the running wheel 1. For example, the above arrangement is used in an in-wheel motor (also referred to as an "in-wheel motor") embodiment shown in fig. 2. That is, as shown in fig. 2, in this case, a permanent magnet in the in-wheel motor is mounted on the mounting shaft 2 of the running wheel 1 as the magnetic member 11, the permanent magnet has a magnetic pole N and a magnetic pole S and forms a magnetic field distribution, and when the mounting shaft 2 rotates the running wheel 1 under power driving, for example, the magnetic field distribution formed by the magnetic pole N and the magnetic pole S is influenced by the magnetic field distribution to generate a magnetic field change, which is associated with the rotating motion state of the running wheel 1, and can be detected and acquired as the running information of the running wheel 1.

Of course, in other embodiments, the invention also allows to configure the magnetic means 11 in any suitable shape, for example square, triangular, etc., and also to arrange them in any possible area on the running wheel (for example so that they are located in a non-central position on the running wheel), provided that the magnetic field provided by the magnetic means 11 can be varied during the rotary movement of the running wheel, and such a variation in the magnetic field can be detected by the detection module 12 and then processed to generate the operating parameter signal S required according to the specific application.

In addition, it should be noted that, by selectively providing the magnetic member 11, the magnetic field variation waveform formed by the magnetic field supplied thereto when the running wheel 1 performs the rotational motion may be a variety of waveforms such as a sine wave, a rectangular wave, and the like. In an alternative case, the magnetic component 11 may be generally configured such that the waveform of the magnetic field variation formed is a sine wave to facilitate the detection process using the detection module 12.

The detection module 12 may be implemented by hardware such as a chip, a processor, or other components, for example, it may be integrated on a Printed Circuit Board (PCB), or it may be implemented by existing components, using software, or by various means such as a combination of software and hardware. The detection module 12 may take the form of a signal sensor, for example, or may be separately designed and fabricated using components such as chips. As another example, in an alternative case, the detection module 12 may be integrally disposed with the magnetic component 11, for example, both of them are installed inside the hub motor, or a part of the detection module 12 (e.g., a part for signal acquisition, etc.) may be integrally installed inside the hub motor with the magnetic component 11, and other parts of the detection module 12 (e.g., a part for data processing, a part for transmitting the operation parameter signal S to the outside, etc.) may be disposed outside the hub motor, for example, at any suitable position on the vehicle on which the hub motor is installed.

In addition, for the operation parameter signal S generated by the detection module 12, it can be transmitted to the corresponding unit, module, device or equipment according to the specific application requirement, and the specific transmission manner can be a wired manner, a wireless manner or a combination manner of the two manners. For example, in some embodiments, the running wheel angle signal S1 in the operating parameter signal S may be communicated to the motor controller 6 (FIG. 2) connected to the detection module 12 for control operations with the operation of the in-wheel motor. For another example, in some embodiments, the speed signal S2 of the running wheel in the running parameter signal S can be transmitted to one or more control devices 7 connected to the detection module 12 and disposed on the vehicle to control the running conditions of the vehicle and some components thereof. When the vehicle is a vehicle, the control device 7 may include, but is not limited to, for example, an ABS (anti lock Braking System), an ESP (Electronic Stability Program), an EMS (Engine Management System), etc., and since the speed of the running wheel is the same as the rotating speed of the mounting shaft of the running wheel, the control device 7 may obtain the current speed information of the vehicle according to the speed signal S2 of the running wheel, and then perform the desired control operation on the vehicle and the corresponding components (such as the Engine, the driving motor, the transmission, etc.) therein.

According to an aspect of the present invention, there is also provided an in-wheel motor, which not only can integrate power, transmission and braking devices into a wheel hub, thereby greatly simplifying the mechanical structure of a vehicle on which the in-wheel motor is mounted, but also can fully utilize the components thereof to acquire and provide an operation parameter signal of an operating wheel on the vehicle. As previously mentioned, such operational parameter signals include at least an angle signal and a speed signal of the running wheel. In contrast to the present invention, since many hub motors currently only acquire the angle signals of the running wheels, and this is only because they need to be provided to the motor controller of the hub motor itself for operating and controlling the motor, those skilled in the art have long learned it and have not understood, recognized or existed the need to provide other running parameter signals besides the above angle signals through the hub motor at the same time. It should be understood that it is the above thought obstacles that are ubiquitous in the industry that limit those skilled in the art from proposing the hub motor that the present invention is designed to provide.

With continued reference to fig. 2, in the embodiment of the hub motor shown, which comprises the stator 3, the rotor 4, the magnetic means 11 and the detection module 12, these means can be arranged inside the housing of the hub motor and mounted and supported on the running wheel 1, for example by means of bearings 5 or other components. As mentioned above, the magnetic means 11 are generally permanent magnets, through which a magnetic field distribution is formed and which, in response to the rotational movement of the running wheel 1, form magnetic field variations which can be detected by the detection module 12 and which generate the operating parameter signals S of the running wheel 1 including at least the angle signal S1, the speed signal S2 discussed above. One significant technical advantage of the present invention compared with the prior art is that two or more kinds of running wheel running parameter signals can be obtained only through the detection module 12 (for example, only one sensor is provided) in the hub motor, and the prior art needs to simultaneously provide numerous components (such as an angle sensor, a speed sensor, an acceleration sensor, etc.) to acquire such running parameter signals, so that it is very beneficial to reduce the system cost, improve the installation convenience, effectively save the space layout, and promote efficient control operation of various control devices, devices or systems, etc., thereby contributing to providing a product with a more compact structure and competitiveness.

It should be noted that the embodiment of the hub motor shown in fig. 2 employs an inner rotor type, which is advantageous for application in high speed environment (e.g. motor speed up to 10000 r/min, etc.), however, the hub motor according to the present invention is not limited to the above structure, and it also fully allows the use of an outer rotor type, which can be adapted to relatively low speed application environment, for example, the hub motor employing an outer rotor type can be applied to electric bicycles, factory transportation trucks, junction vehicles, etc.

Further, according to an aspect of the present invention, there is provided a vehicle which may include, but is not limited to, many types of vehicles such as fuel vehicles, electric vehicles, hybrid vehicles, electric bicycles, aircraft, and the like. According to the design concept of the present invention, the wheel hub motor designed and provided according to the present invention can be installed on one or more running wheels of the vehicle, or the running wheel operation parameter detection device designed and provided according to the present invention can be installed on the vehicle, for example, the running wheel operation parameter detection device can be installed on one or more running wheels of the vehicle, for example, the magnetic component in the running wheel operation parameter detection device can be directly installed on the running wheels of the vehicle, and meanwhile, a part of the detection module (such as a part for performing data processing, a part for transmitting the operation parameter signal S outwards, and the like) can be installed at any suitable position on the vehicle. By adopting the above vehicle, the obvious technical advantages of the scheme of the invention, as described above, can be fully exerted.

The invention has been described in detail with reference to the running wheel operation parameter detecting apparatus, the in-wheel motor and the vehicle, which are provided by way of example only, and the examples are not intended to limit the invention, but to illustrate the principles of the invention and its embodiments, and various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. Accordingly, all equivalents are intended to be included within the scope of this invention and defined in the claims which follow.
