Description

Technical Field

[0001] The present invention relates to the field of vehicle chargers, and more specifically, to a single-motor dual-drive mechanism and a vehicle wireless charger. Background Art

[0002] Vehicle wireless chargers are used in vehicles and can provide the function of clamping mobile phones. The mobile phone clamping part of the vehicle wireless charger can also provide the function of wirelessly charging the mobile phone. In order to achieve product automation, there have emerged vehicle wireless chargers on the market that can automatically clamp mobile phones with a clamping arm, automatically detect mobile phones with a wireless charging coil, and automatically align with the mobile phones.

[0003] However, the existing automated vehicle wireless chargers have a complex structure and require two drive motors to drive the clamping function of the clamping arm and the function of moving and aligning the wireless charging coil respectively, resulting in large size, very heavy weight, occupying a large space in the vehicle, and inconvenient installation.

[0004] The above problems are worthy of solution. Summary of the Invention

[0005] In order to overcome the deficiencies of the existing technology, the present invention provides a single-motor dual-drive mechanism and a vehicle wireless charger.

[0006] The technical solution of the present invention is as follows:

[0007] A single-motor dual-drive mechanism includes a first force-bearing moving mechanism and a second force-bearing moving mechanism. It is characterized in that it further includes a motor, and an upper gear and a lower gear are provided on the output shaft of the motor. The motor drives the upper gear and the lower gear to rotate synchronously, and the two gears can slide up and down synchronously along the output shaft;

[0008] When the upper gear and the lower gear slide up to the corresponding first position, the upper gear meshes with the first force-bearing moving mechanism, and the lower gear disengages from the second force-bearing moving mechanism. The motor drives the first force-bearing moving mechanism through the upper gear;

[0009] When the upper gear and the lower gear slide down to the corresponding second position, the upper gear disengages from the first force-bearing moving mechanism, and the lower gear meshes with the second force-bearing moving mechanism. The motor drives the second force-bearing moving mechanism through the lower gear.

[0010] According to the present invention of the above solution, it is characterized in that a threaded central screw is provided on the output shaft of the motor, and the upper gear and the lower gear are both sleeved on the central screw and threadedly connected to the central screw.

[0011] The present invention according to the above solution is characterized in that, along the upward direction, the screw threads on the axial screw rotate clockwise and extend, and the upper gear and the lower gear are both provided with thread grooves in the same direction as the screw threads.

[0012] The present invention according to the above solution is characterized in that an upper spring is provided between the upper gear and the lower gear, and a lower spring is provided between the lower gear and the motor. As the upper gear slides down to its second position, the upper spring gradually pushes the lower gear. As the lower gear slides down to its second position, the lower spring gradually contracts and obtains the elastic force to reset the lower gear.

[0013] On the other hand, the present invention also provides a vehicle-mounted wireless charger, including a housing, a coil moving assembly and an elastic clamping assembly provided on the housing, and is characterized in that it further includes the single-motor dual-drive mechanism according to the above solution;

[0014] When the upper gear and the lower gear of the single-motor dual-drive structure slide up to the corresponding first positions, the upper gear meshes with the coil moving assembly, and the lower gear disengages from the elastic clamping assembly;

[0015] When the upper gear and the lower gear slide down to the corresponding second positions, the upper gear disengages from the coil moving assembly, and the lower gear meshes with the elastic clamping assembly.

[0016] The present invention according to the above solution is characterized in that the coil moving assembly includes a coil sliding plate and a sliding plate spring for driving the coil sliding plate to reset. The sliding plate spring is in a stretched state, and the coil sliding plate can slide back and forth along the housing.

[0017] The present invention according to the above solution is characterized in that the coil sliding plate is provided with a sliding plate rack. When the motor rotates counterclockwise, the upper gear slides up to its first position and meshes with the sliding plate rack, and the motor drives the coil sliding plate to slide towards the bottom of the vehicle-mounted wireless charger through the upper gear; when the motor rotates clockwise, the sliding plate spring drives the coil sliding plate to reset.

[0018] The present invention according to the above solution is characterized in that the housing is provided with a slide rail, and the coil sliding plate is provided with a chute corresponding to the position of the slide rail, and the slide rail on the coil sliding plate slides back and forth along the chute.

[0019] The present invention according to the above solution is characterized in that the elastic clamping assembly includes clamping arms and a clamping arm spring for driving the clamping arms to reset. The clamping arm spring is in a stretched state, and the clamping arms can slide left and right along the housing.

[0020] The present invention according to the above solution is characterized in that a clamping arm rack is provided on the clamping arm. When the motor rotates clockwise, the lower gear slides down to its second position and meshes with the clamping arm rack, and the motor drives the clamping arm to slide outward through the lower gear.

[0021] The beneficial effect of the present invention according to the above solution is as follows:

[0022] The single-motor double-drive mechanism of the present invention can drive the movement of two force-bearing moving mechanisms with one motor, which is beneficial to simplifying the structure of the device and reducing the size of the device;

[0023] The on-vehicle wireless charger of the present invention uses one motor to not only drive the elastic clamping assembly to clamp the mobile phone to be charged, but also drive the coil moving assembly to automatically align the wireless charging coil with the mobile phone, thus making the structure simple, saving costs and reducing the product volume, and saving the in-vehicle use space.

[0037] In order to better understand the purpose, technical solution and technical effect of the present invention, the present invention will be further explained below in conjunction with the drawings and embodiments. At the same time, it is declared that the embodiments described below are only used to explain the present invention and are not used to limit the present invention.

[0038] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0039] The orientations or positions indicated by the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc. are based on the orientations or positions shown in the drawings, and are only for the convenience of description and cannot be understood as a limitation to the technical solution of the present application.

[0040] The terms "first" and "second" are only used for the purpose of convenient description and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of technical features.

[0041] The meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0042] As Figures 1-4 shown, a single-motor 1 double-drive mechanism includes a motor 1, a first force-bearing moving mechanism and a second force-bearing moving mechanism. An upper gear 2 and a lower gear 3 are provided on the output shaft 101 of the motor 1. The motor 1 drives the upper gear 2 and the lower gear 3 to rotate synchronously, and the two gears can slide up and down synchronously along the output shaft 101. When the upper gear 2 and the lower gear 3 slide up to the corresponding first positions (that is, the upper gear 2 slides to the first position of the upper gear 2, and the lower gear 3 slides to the first position of the lower gear 3), the upper gear 2 meshes with the first force-bearing moving mechanism, and the lower gear 3 disengages from the second force-bearing moving mechanism, so that the motor 1 drives the first force-bearing moving mechanism; when the upper gear 2 and the lower gear 3 slide down to the corresponding second positions, the upper gear 2 disengages from the first force-bearing moving mechanism, and the lower gear 3 meshes with the second force-bearing moving mechanism. At this time, the motor 1 drives the second force-bearing moving mechanism.

[0043] The "synchronization" described in the present invention is a broad sense of synchronization, which does not mean that the upper gear and the lower gear are in the same state at every moment. That is, when the upper gear moves downward, it will drive the lower gear to move downward. At the moment when the state changes, the lower gear can have an instantaneous state change delay relative to the upper gear.

[0044] It can be seen that compared with the prior art that uses two motors to drive two force-bearing moving mechanisms respectively, the single-motor dual-drive mechanism of the present invention can drive two force-bearing moving mechanisms to move with only one motor, which is beneficial to simplifying the structure of the device and reducing the size of the device.

[0045] In this embodiment, a threaded central screw 4 is provided on the output shaft 101 of the motor 1. The upper gear 2 and the lower gear 3 are both sleeved on the central screw 4 and are threadedly connected to the central screw 4. When the central screw 4 rotates with the output shaft 101 of the motor 1, the upper gear 2 and the lower gear 3 can slide up and down along the screw thread on the central screw 4.

[0046] The screw thread on the central screw 4 extends clockwise along the bottom-up direction. The inner ring side walls of the upper gear 2 and the lower gear 3 are both provided with thread grooves that are in the same direction as and match the screw thread. When the gears are restricted in their rotation state by external forces, the upper gear 2 and the lower gear 3 will slide with the rotation of the motor 1. For example, if the upper gear 2 is blocked, it will slide down along the screw thread, and if the lower gear 3 is blocked, it will slide up along the screw thread.

[0047] In other embodiments, the screw thread can also be designed to be counterclockwise. This structure only changes the relationship between the rotation direction of the motor 1 and the up-and-down directions of the two gears, and does not affect the function implementation, and all fall within the protection scope of the present invention. For example, in this embodiment, the screw thread of the central screw 4 is in the clockwise direction, so when the motor 1 rotates counterclockwise, the gears can slide up, and when the motor 1 rotates clockwise, the gears can slide down; on the contrary, if the screw thread of the central screw 4 is in the counterclockwise direction, when the motor 1 rotates clockwise, the gears can slide up, and when the motor 1 rotates counterclockwise, the gears can slide down.

[0048] An upper spring 5 is provided between the upper gear 2 and the lower gear 3, and a lower spring 6 is provided between the lower gear 3 and the motor 1. The upper spring 5 is used to transmit the acting force between the two gears, so that the two gears slide up and down synchronously. For example, when the upper gear 2 slides down to its second position, the lower gear 3 is pushed to slide down synchronously through the upper spring 5. When the lower gear 3 slides up to its first position under the action of the lower spring 6, the upper gear 2 is pushed to slide up synchronously through the upper spring 5. As a power transmission member between the two gears, the upper spring 5 can also provide a torsional buffering effect between the two gears, making the gears smoother during the sliding and state change processes, reducing the burden on the motor 1. For example, when the rotation state of the upper gear 2 is blocked and it slides instantaneously, the lower gear 3 still rotates with the motor 1. There is a rotational speed difference between the upper and lower gears 3. After the upper gear 2 completely disengages from the first force-bearing moving mechanism, the two gears continue to rotate synchronously.

[0049] The lower spring 6 is used to reset the lower gear 3 to the first position. As the lower gear 3 slides down to its second position, the lower spring 6 gradually contracts and obtains the elastic force for resetting the lower gear 3.

[0050] In a preferred embodiment, the distance that the upper gear 2 moves from its first position P1 to its second position P2 is equal to the wall thickness of the upper gear 2, and the distance that the lower gear 3 moves from its second position Q2 to its first position Q1 is equal to the wall thickness of the lower gear 3. Specifically, in this embodiment, the first position P1 of the upper gear 2 is the position when it meshes with the first force-bearing moving component, and the second position P2 of the upper gear 2 is the position when it just disengages from the first force-bearing moving component; the first position Q1 of the lower gear 3 is the position when it just disengages from the second force-bearing moving component, and the second position Q2 of the lower gear 3 is the position when it meshes with the second force-bearing moving component.

[0051] In other embodiments, the upper spring can be replaced with other elastic or inelastic components to connect the upper gear and the lower gear; the lower spring can also be replaced with other elastic components that can provide elastic force.

[0052] In an alternative embodiment, the central axis screw 4 is composed of an upper central axis screw 401 and a lower central axis screw 402. A gear group limit cover plate 102 is provided at the top of the upper central axis screw 401 to prevent the gears from slipping out of the central axis screw 4; a gear group support ring 103 is provided at the bottom of the lower central axis screw 402 to limit the lowest position of the downward movement of the lower gear 3, and at the same time enable the lower gear 3 to rotate smoothly at the lowest position after sliding down in place, so as to better perform power transmission.

[0053] Such as Figure 5 and Figure 6As shown in the figure, the present invention also provides a vehicle-mounted wireless charger, which includes a housing, a coil moving assembly 8 and an elastic clamping assembly 9 provided on the housing, and also includes the single-motor dual-drive mechanism in the above solution. When the upper gear 2 and the lower gear 3 of the single-motor dual-drive structure slide to the corresponding first positions, the upper gear 2 meshes with the coil moving assembly 8, and the lower gear 3 disengages from the elastic clamping assembly 9; when the upper gear 2 and the lower gear 3 slide down to the corresponding second positions, the upper gear 2 disengages from the coil moving assembly 8, and the lower gear 3 meshes with the elastic clamping assembly 9.

[0054] The elastic clamping assembly 9 includes a pair of openable and closable clamping arms 901 for clamping an electronic device to be charged, such as a common mobile phone, while the coil moving assembly 8 carries a wireless charging coil 804 to control the back-and-forth movement of the wireless charging coil 804. Therefore, the vehicle-mounted wireless charger of the present invention drives both the elastic clamping assembly to clamp the mobile phone to be charged and the coil moving assembly by one motor to automatically align the wireless charging coil with the mobile phone.

[0055] It should be noted that when the wireless charging coil 804 moves to the position of the mobile phone battery, a relatively large current can be output to obtain a feedback signal, and then the control system controls the motor 1 to stop driving the coil moving assembly 8 to complete the automatic alignment of the wireless charging coil 804 with the mobile phone battery.

[0056] In this embodiment, the coil moving assembly 8 includes a coil sliding plate 801 and a sliding plate spring 803 for driving the coil sliding plate 801 to reset. One end of the sliding plate spring 803 is fixed to the middle plate 703 of the housing, and the other end is fixed to the coil sliding plate 801. The sliding plate spring 803 is in a stretched state, so as to apply a pulling force on the coil sliding plate 801. When the coil sliding plate 801 slides towards the bottom of the vehicle-mounted wireless charger driven by the upper gear 2 of the single-motor dual-drive mechanism, since the driving force direction (the rotation direction of the upper gear 2) is opposite to the elastic pulling force direction of the sliding plate spring 803, the elastic force of the sliding plate spring 803 gradually increases, and the pulling force applied on the coil sliding plate 801 also increases accordingly; when the driving force direction is along the elastic pulling force direction of the sliding plate spring 803, the sliding plate spring 803 drives the coil sliding plate 801 to slide towards the top of the vehicle-mounted wireless charger. In this process, the upper gear 2 rotates synchronously with the motor 1, playing a role in stabilizing the sliding of the coil sliding plate 801. Therefore, the coil sliding plate 801 can slide back and forth along the housing.

[0057] In a preferred embodiment, a sliding plate rack 802 is provided on the coil sliding plate 801. When the motor 1 rotates counterclockwise, the upper gear 2 slides upward to its first position and meshes with the sliding plate rack 802. The motor 1 drives the coil sliding plate to slide towards the bottom of the vehicle-mounted wireless charger through the upper gear 2, completing the alignment of the wireless charging coil 804 with the mobile phone battery. When the motor 1 rotates clockwise, the sliding plate spring 803 drives the coil sliding plate 801 to reset, and the coil sliding plate 801 slides towards the top of the vehicle-mounted wireless charger. During this process, since the upper gear 2 follows the sliding plate rack 802, the upper gear 2 rotates synchronously with the motor 1 and will not slide down.

[0058] In an alternative embodiment, a slide rail is provided on the housing, and a slide groove corresponding to the position of the slide rail is provided on the coil sliding plate 801. The slide rail on the coil sliding plate 801 slides back and forth along the slide groove.

[0059] In this embodiment, the elastic clamping assembly 9 includes clamping arms 901 and a clamping arm spring 902 for driving the clamping arms 901 to reset. The clamping arm spring 902 is in a stretched state, and the clamping arms 901 can slide left and right along the housing. The clamping arms 901 include a left clamping arm and a right clamping arm. A left clamping arm spring is provided on the left clamping arm, and a right clamping arm spring is provided on the right clamping arm. Both the left clamping arm spring and the right clamping arm spring are in a stretched state. When the left and right clamping arms open on both sides, the elastic force of the left and right clamping arm springs gradually increases.

[0060] In a preferred embodiment, a clamping arm rack 903 is provided on the clamping arms 901. When the motor 1 rotates clockwise, the lower gear 3 slides downward to its second position and meshes with the clamping arm rack 903. The motor 1 drives the two clamping arms 901 to slide outward through the lower gear 3, and the clamping arms 901 gradually open. Specifically, in this embodiment, a transmission gear 705 and a clamping arm driving gear 706 are provided on the housing. The transmission gear 705 meshes with the clamping arm driving gear 706, and the clamping arm driving gear 706 meshes with the clamping arm rack 903. When the lower gear 3 slides downward to its second position, it meshes with the transmission gear 705 to realize meshing with the clamping arm rack 903.

[0061] When the motor 1 rotates counterclockwise, the rotation direction of the lower gear 3 is along the elastic pulling direction of the clamping arm spring 902, and the clamping arm spring 902 drives the clamping arms to clamp back. During this process, the lower gear 3 rotates synchronously with the motor 1, playing a role in stabilizing the gradual tightening of the clamping arms 901.

[0062] In an alternative embodiment, the housing includes a bottom case 701, a middle plate 703, and a face cover 702. The middle plate 703 is fixed in the space enclosed by the bottom case 701 and the face cover 702. The coil sliding plate 801 is provided on the upper side of the middle plate 703, and the coil sliding plate 801 slides back and forth along the middle plate 703; the clamping arms 901 are provided on the lower side of the middle plate 703, and the clamping arms 901 slide left and right along the middle plate 703.

[0063] The present invention also provides a method for implementing a vehicle-mounted wireless charger. In this embodiment, the screw thread of the screw adopts the clockwise direction design in the above solution, and the steps are as follows:

[0064] S1. The clamping arms of the elastic clamping assembly open, and the mobile phone is placed in.

[0065] S101. The motor rotates clockwise. Due to the action of the upper gear and the upper spring, the lower gear slides down along the screw thread of the central screw and meshes into the transmission gear.

[0066] S102. The lower gear compresses the lower spring. After the lower gear moves down to the bottom and abuts against the gear group support ring, it no longer slides down and rotates clockwise with the motor.

[0067] S103. The lower gear drives the clamping arm driving gear to rotate clockwise through the transmission gear, and the two clamping arms open.

[0068] S104. The mobile phone is placed on the clamping position, and step S2 is entered.

[0069] S2. The clamping arms tighten and clamp the mobile phone.

[0070] S201. The control system makes the motor rotate counterclockwise. Under the action of the clamping arm spring and the lower gear, the clamping arms gradually close.

[0071] S202. After the clamping arms clamp the mobile phone or reach the position, the rotation state of the lower gear is blocked. At the same time, under the elastic force of the lower spring, the lower gear slides up along the central screw until it disengages from the elastic clamping assembly.

[0072] S203. The lower gear pushes the upper gear up through the upper spring, and step S3 is entered.

[0073] S3. The coil moving assembly moves into position and starts charging.

[0074] S301. The upper gear slides up along the central screw under the action of the lower gear and the upper spring and meshes into the coil sliding plate.

[0075] S302. After the upper gear slides up to abut against the gear group limit cover plate, it no longer slides up and rotates counterclockwise with the motor.

[0076] S303. The upper gear drives the coil sliding plate to slide towards the bottom of the vehicle-mounted wireless charger through the sliding plate rack.

[0077] S304. After the wireless charging coil is aligned with the mobile phone charging area, the motor stops rotating and starts charging.

[0078] S4. The elastic clamping assembly opens and the mobile phone is taken out.

[0079] S401. After the charging is completed, the motor rotates clockwise. Under the action of the sliding plate spring and the upper gear, the coil sliding plate moves towards the top of the vehicle-mounted wireless charger;

[0080] S402. After the coil sliding plate moves to the top, the rotation state of the upper gear is blocked, and it slides down along the axial screw until it disengages from the coil moving assembly;

[0081] S403. The upper gear pushes the lower gear to slide down through the upper spring, so that the lower gear meshes into the elastic clamping assembly;

[0082] S404. Similar to the above steps S101 - S103, the clamping arms open and the mobile phone is removed.

[0083] Therefore, the present invention realizes dual drive through one motor to complete the automatic alignment of clamping the mobile phone and the wireless charging coil.

[0084] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0085] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
