Glass lifting driving mechanism comprising storage battery

Abstract

The utility model relates to a storage battery-containing glass lifting driving mechanism of a movable vehicle window of a vehicle, which specifically comprises a guide rail, a linear motor and a mounting body, and the mounting body is fixed on a rotor of the linear motor and can be guided by the guide rail. The linear motor drives the rotor to move relative to the stator under the excitation effect so that the glass can be guided to move between the bottom and the top along the guide rail, and therefore the lifting position of the glass can be changed. The storage battery is fixed on the mounting body to supply power to the linear motor and is configured to be in an electric conduction state with the linear motor all the time, and because the storage battery is carried on the mounting body, the storage battery becomes a part of the glass lifting driving mechanism and moves along with the movement of the mounting body; the operation of lifting the glass is irrelevant to the electric energy condition of the vehicle, and the operation of lifting the glass can be independently carried out.

Description

Technical Field

[0001] The utility model belongs to a movable window regulating system, and more specifically, relates to a movable window regulating system applied to a vehicle, and used for performing a glass lifting and lowering driving operation. Background Art

[0002] The applicant has applied for Chinese utility model patent 2024201394090 for a glass lifting drive mechanism, which includes: a guide rail having a body extending from the bottom to the top; a linear motor, which includes a stator and a mover, wherein the stator is a magnetic rail, which extends from the bottom to the top and is installed along the length direction of the body of the guide rail; a mounting body, which is fixed on the mover and can be guided by the guide rail, and the glass can be fixed on the mounting body; wherein the linear motor drives the mover relative to the stator to guide the glass to move between the bottom and the top along the guide rail, thereby changing the glass lifting position. Compared with the traditional glass lifting drive mechanism using a rotary motor as a power component, the glass lifting drive mechanism using a linear motor has a simple structure and a small size. This is because the linear motor does not require an additional device to convert the rotary motion into a linear motion, thereby greatly simplifying the structure of the system itself, and greatly reducing the weight and volume. However, the electric energy of this glass lifting drive mechanism is completely dependent on the outside. If the vehicle cannot power the glass lifting drive mechanism, the glass of the window will not be able to perform the lifting drive. Utility Model Content

DETAILED DESCRIPTION

[0018] The above and other technical features and functions of the present invention are described in detail below with reference to the attached Figures 1 to 6 The embodiments are described in detail.

[0019] definition:

[0020] Linear motor: Also known as linear motor, it is a motor that can produce linear motion. Its main feature is that it converts electrical energy directly into mechanical energy for linear motion. This process does not require any intermediate conversion mechanism or transmission device. Therefore, compared with the linear motion formed by the conversion device of the rotary motor, its efficiency is higher. During the rotation of the DC motor, excitation is to control the voltage of the stator to change the magnetic field it produces, changing the speed of the DC motor. Changing the excitation also plays a role in changing the speed. Compared with rotary motors, linear motors have the following main features:

[0021] First, the structure is simple. Since the linear motor does not need additional devices to convert the rotary motion into linear motion, the structure of the system itself is greatly simplified, and the weight and volume are greatly reduced.

[0022] Second, the positioning accuracy is high. Where linear motion is required, the linear motor can achieve direct transmission, thereby eliminating various positioning errors caused by the intermediate links. Therefore, the positioning accuracy is high. If microcomputer control is adopted, the positioning accuracy of the entire system can be greatly improved.

[0023] Third, it has fast response speed, high sensitivity and good follow-up performance. It is easy for the linear motor to use magnetic suspension to support its mover, so that a certain air gap is always maintained between the mover and the stator without contact, which eliminates the contact friction resistance between the stator and the mover, thus greatly improving the sensitivity, rapidity and follow-up performance of the system;

[0024] Fourth, it is safe and reliable in operation and has a long service life. Linear motors can achieve contactless force transmission, and the mechanical friction loss is almost zero, so there are few failures and maintenance-free, so it is safe and reliable in operation and has a long service life.

[0025] Photoelectric switch: A photoelectric switch is a type of sensor that converts the intensity change of light between the transmitting end and the receiving end into the change of current to achieve the purpose of detection. Since the output circuit and input circuit of the photoelectric switch are electrically isolated (ie, electrically insulated), it can be used in many occasions.

[0026] Magnetic scale: Magnetic scale is a linear displacement measurement solution commonly used in the field of industrial automation equipment. Because of its strong durability and low environmental requirements, it has gradually replaced the optical linear measurement solution with strict environmental requirements. The magnetic scale is mainly composed of two parts, the magnetic scale and the read head. The magnetic scale is an important component of the magnetic scale displacement sensor, providing a reference for the displacement measurement and position positioning of the sensor. The magnetic scale is composed of a non-magnetic stainless steel belt, a magnetic material, and a protective layer. The read head is a conversion device for magnetic-electric conversion. It converts the magnetization signal recorded on the magnetic scale into an electrical signal and transmits it to the detection circuit to achieve displacement measurement or position positioning. The read head is also a key component of the magnetic scale displacement sensor. It mainly consists of an excitation winding and a signal output winding. The read head converts the detected magnetic signal into a pulse signal through the excitation voltage supplied by the excitation winding for dynamic or static measurement. The read head and the magnetic scale are read through a non-contact installation. The read head senses the change in the magnetic field during the movement along the magnetic scale and converts this magnetic field change into an analog signal or a digital signal output.

[0027] Magnetic cable: Magnetic cable, also known as magnetic charging cable or magnetic charging cable, is a convenient charging and data transmission tool that uses magnetic connection technology to simplify the traditional plug-in and unplug process. The design of the magnetic cable usually includes one or more magnetic heads, which can be tightly adsorbed to the corresponding interface on the device to achieve electrical connection. This design can reduce wear during plugging and unplugging and extend the service life of the cable and device interface. Magnetic cables are widely used in smart wearable devices, 3C digital products, smart homes, car navigation systems, and medical equipment. They use magnetic adsorption to facilitate users to quickly connect and disconnect when charging or transferring data.

[0028] Embodiment 1:

[0029] Here, refer to Figure 1 Before explaining the glass lifting drive mechanism, the vehicle door including the same will be explained first. The vehicle door (not shown in the figure) comprises: a door body (not shown in the figure); a vehicle window glass supported to be able to be lifted and lowered along the R line (i.e., the moving path of the glass lifting drive mechanism provided on the door body); and a glass lifting drive mechanism which is assembled to the door body to lift and lower the window glass.

[0030] The door body has a storage portion for storing the window glass and a door window frame disposed above the storage portion. The storage portion has an inner panel on the inside of the vehicle compartment as a door panel and an outer panel (not shown) on the outside of the vehicle compartment, and a door internal space is formed between the inner panel and the outer panel. Figure 1 As shown, the glass lifting and lowering drive mechanism is installed to be inclined toward the rear side in the vehicle front-rear direction relative to the door body.

[0031] A glass lifting drive mechanism including a battery comprises: a guide rail having a guide rail body 16 extending from the bottom to the top; a linear motor comprising a stator and a mover, wherein the mover is an excitation structure, and the stator is a magnetic rail extending from the bottom to the top and installed along the length direction of the guide rail body 16;

[0032] The mounting body 10 is fixed on the mover and can be guided by the guide rail, and the glass can be fixed on the mounting body 10 through the support block; wherein, the linear motor drives the mover to move relative to the stator under the action of excitation to guide the glass to move between the bottom and the top along the guide rail 22, thereby changing the glass lifting position; compared with the traditional glass lifting drive mechanism using a rotary motor as a power component, the glass lifting drive mechanism using a linear motor has a simple structure and a small size. This is because the linear motor does not require an additional device to convert the rotary motion into a linear motion, thereby greatly simplifying the structure of the system itself, and greatly reducing the weight and volume. The single-track glass lifting saves costs and is not limited by the length of the stroke. The total weight of the lifter is about 5KG.

[0033] It also includes: a battery 11, which is fixed on the mounting body 10 to power the linear motor and is configured to always maintain an electrically conductive state with the linear motor regardless of the change in the position of the glass. Since the battery is mounted on the mounting body, the battery becomes a part of the glass lifting drive mechanism and moves with the movement of the mounting body. The battery can be connected to the linear motor stator in a simple way. Since the glass lifting drive mechanism has its own battery as an energy supply mechanism, the operation of lifting the glass is independent of the power situation of the vehicle, and the operation of lifting the glass can be performed independently, and there will be no problem that the vehicle's battery power is insufficient and the door glass cannot be lifted or lowered.

[0034] Embodiment 2:

[0035] In addition to the contents of the above-mentioned embodiments, the present embodiment includes a first connector 32, which is fixed on the guide rail body 16 and electrically connected to an external power source; a second connector 33, which is fixed on the mounting body 10 and electrically connected to the battery 11; wherein, when the first connector 32 is connected to the second connector 33, the external power source can charge the battery 11. The external power source here refers to a battery other than the glass lifting drive mechanism including the battery. For example, an electric car uses a battery to power the wheels. The guide rail body 16 has a flat plate portion, which extends in the lifting direction; a right side plate portion and a left side plate portion, which are erected from the left and right ends in the short side direction of the flat plate portion (in a direction orthogonal to the lifting direction) to the front side; a right guide flange, which protrudes from the front end of the right side plate portion to the right side; and a left guide flange, which protrudes from the front end of the left side plate portion to the left side. The guide rail uses a slider to slide freely at the guide flanges on both sides.

[0036] In this embodiment, the technical means for charging the battery 11 are further described. The glass lifting and lowering driving mechanism including the battery includes a magnetic wire.

[0037] In this embodiment, the first joint 32 and the second joint 33 are both arranged on the glass moving path R, and the mounting body 10 moves on the glass moving path R. At the set position, the first joint 32 and the second joint 33 can be electrically connected, and at this time, the external power supply can charge the battery 11.

[0038] Preferably, the mounting body 10 is moved to the end position of the glass raising, and the first joint 32 is connected to the second joint 33. When the glass is fully raised, it is the normal state of the door. In this state, the battery 11 is charged by an external power supply.

[0039] Embodiment 3:

[0040] In addition to the contents of the aforementioned embodiments, the present embodiment includes the following: the battery 11 is fixed to the first surface of the mounting body 10 and is limited by the fixing buckle 13; the second connector 33 is fixed to the second surface of the mounting body 10 and is stuck in the groove of the mounting plate; the first connector 32 is fixed on the guide rail body 16 and is installed in the direction of the second connector 33.

[0041] This layout of the battery 11 and the magnetic wire can save installation space as much as possible and adapt to the narrow installation structure of the vehicle door.

[0042] Embodiment 4:

[0043] In addition to the contents of the above embodiments, the glass lifting drive mechanism in this embodiment further describes the auxiliary locking components, that is, the photoelectric switches and magnetic scales are installed at both ends of the bottom and top to monitor the position of the mover in real time.

[0044] The glass lifting and lowering driving mechanism also includes a photoelectric position sensor, which includes a detection plate, a first position sensor located at the top and a second position sensor located at the bottom respectively, and the detection plate can be detected by the first position sensor and the second position sensor.

[0045] The glass lifting drive mechanism also includes a magnetic scale, which includes a magnetic scale and a reading head. The reading head is fixed on the mounting body. The magnetic scale extends from the bottom to the top and is installed along the length direction of the guide rail body.

[0046] The principles and methods of the photoelectric switch and the magnetic scale have been described above. Those skilled in the art will appreciate that it is also possible to use either the photoelectric switch or the magnetic scale alone as the auxiliary locking element.

[0047] The above description is only for illustrating the present invention, and it should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the protection scope of the present invention.
