Technical Field

[0001] This application relates to the field of wireless charging technology, and particularly to an electric energy transmitting platform and a charging system. Background Art

[0002] In recent years, the application of wireless charging technology in the vehicle field has become a research hotspot. A wireless charging system generally consists of two parts: an electric energy transmitting device and an electric energy receiving device. Among them, the electric energy transmitting device transmits electric energy to the electric energy receiving device through a magnetic field, and the electric energy receiving device then delivers the electric energy to the vehicle's battery, thereby achieving wireless charging. However, the charging efficiency of the current wireless charging system applied to the vehicle field is not high. Summary of the Invention

[0003] This application provides an electric energy transmitting platform and a charging system, and the electric energy transmitting platform can improve the charging efficiency.

[0004] This application provides an electric energy transmitting platform for charging a vehicle. The electric energy transmitting platform has a first state and a second state. When the electric energy transmitting platform is in the first state, the height of the electric energy transmitting platform is a first height; when the electric energy transmitting platform is in the second state, the height of the electric energy transmitting platform is a second height, and when in the second state, the electric energy transmitting platform is used to abut against the electric energy receiving platform on the vehicle, and the electric energy transmitting platform is used to deliver electric energy to the vehicle through the electric energy receiving platform, where the first height is greater than the second height.

[0005] Wherein, the electric energy transmitting platform includes a housing, a telescopic sleeve and a transmitting device. The housing and the telescopic sleeve jointly enclose a receiving space for receiving the transmitting device. The housing is used to abut against the electric energy receiving platform. When the electric energy transmitting platform switches from the first state to the second state, the housing is abutted, and the self-height of the telescopic sleeve gradually decreases.

[0006] Wherein, the electric energy transmitting platform may further include an elastic structure with compressive elasticity. The elastic structure is arranged in the receiving space jointly enclosed by the housing and the telescopic sleeve, and the elastic structure is connected to the housing. When the electric energy transmitting platform switches from the first state to the second state, the elastic structure is compressed by the housing, and when the electric energy transmitting platform switches from the second state to the first state, the elastic structure provides an elastic force to the housing.

[0007] Wherein, the housing includes an abutting portion and a first guiding portion connected to each other. The abutting portion is configured to abut against the power receiving platform in the second state, and the first guiding portion is configured to abut against the power receiving platform during the process of converting from the first state to the second state, so as to guide the power receiving platform to the abutting portion.

[0008] Wherein, the power transmitting platform further includes a guiding member detachably connected to a side of the first guiding portion away from the abutting portion. The guiding member is configured to abut against the power receiving platform during the process of converting from the first state to the second state, so as to guide the power receiving platform to the first guiding portion.

[0009] Wherein, the housing further includes a second guiding portion connected to a side of the abutting portion away from the first guiding portion. The second guiding portion is configured to abut against the power receiving platform during the process of converting from the first state to the second state, so as to guide the power receiving platform to the abutting portion.

[0010] Wherein, in a direction of the telescopic sleeve towards the housing, the abutting portion protrudes from the transmitting device.

[0011] Wherein, the telescopic sleeve includes a plurality of deformation portions connected in sequence. Each deformation portion includes a first side wall and a second side wall, and an included angle is formed between the adjacent first side wall and the second side wall. During the process of the power transmitting platform converting from the first state to the second state, the included angle gradually decreases, and during the process of the power transmitting platform converting from the second state to the first state, the included angle gradually increases.

[0012] Wherein, the power transmitting platform further includes a cover plate connected to the housing. The cover plate, the housing and the telescopic sleeve jointly enclose the accommodation space. The cover plate has an opening communicating with the accommodation space, and the transmitting device is exposed to the outside through the opening.

[0013] Wherein, the opening includes a first opening and a second opening arranged at intervals. The area size of the transmitting device exposed from the first opening is 10 cm × 10 cm, and the area size of the transmitting device exposed from the second opening is 10 cm × 10 cm.

[0014] The present application further provides a charging system, which includes a power transmitting device and a power receiving device. The power transmitting device includes a power transmitting platform configured to transmit power to the power receiving device.

[0015] When the power transmission platform provided by this application is used to charge a vehicle, the power transmission platform and the power reception platform are abutted against each other, so that the gap between the power transmission platform and the power reception platform can be avoided, thereby improving the charging efficiency. Moreover, since there is no such gap, it is not necessary to add the two functions of foreign object detection and living body protection, thus saving costs. Brief Description of the Drawings

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0034] The terms "first", "second", etc. in the specification and claims of the present application and the above accompanying drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0035] References herein to "embodiments" mean that the particular features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments in the case where there is no contradiction when at least two embodiments are combined together.

[0036] Please refer to Figures 1 to 3 , the present application provides a charging system 1. Specifically, the charging system 1 includes a power transmitting device 2 and a power receiving device 3. The power transmitting device 2 is connected to the power grid and is used to generate a magnetic field. The power receiving device 3 is used to generate an induced current in the magnetic field and deliver electrical energy to the battery 41 of the vehicle 4. In other words, the power transmitting device 2 transmits electrical energy to the power receiving device 3 through the magnetic field, thereby realizing wireless charging. Among them, the power transmitting device 2 is installed on the ground, and the power receiving device 3 is installed on the chassis of the vehicle 4.

[0037] Among them, the power transmitting device 2 includes a first control device 21 and a power transmitting platform 22 that are electrically connected. The power receiving device 3 includes a second control device 31 and a power receiving platform 32 that are electrically connected. During the charging process, the industrial frequency alternating current of the power grid serves as the energy supply source. The industrial frequency alternating current is rectified and inverted by the first control device 21 to become high-frequency alternating current, and then the high-frequency alternating current is converted into a magnetic field through the power transmitting platform 22. The power receiving platform 32 generates an induced current in the magnetic field, and then the induced current is converted into direct current through the second control device 31 to charge the battery 41 of the vehicle 4.

[0038] The following specifically introduces the power transmitting platform 22 in the charging system 1 provided by the above embodiment with reference to the accompanying drawings.

[0039] Please refer to Figure 4, the present application also provides an electric energy transmitting platform 22, which is used to charge the vehicle 4. For the specific charging principle, please refer to the description in the above embodiments. The electric energy transmitting platform 22 has a charging side B and a mounting side A. The charging side B is used to face the electric energy receiving platform 32 for charging, and the mounting side A is used to be set on the ground. Among them, the vehicle 4 can be, but is not limited to, a sedan, a multi-purpose vehicle (MPV), a sport utility vehicle (SUV), an off-road vehicle (ORV), a pickup truck, a minivan, a bus, a truck, etc. The electric energy transmitting platform 22 is arranged on the ground of a garage (or a parking space). When the vehicle 4 needs to be charged, it drives into the garage and aligns the electric energy receiving platform 32 installed on the chassis with the electric energy transmitting platform 22, and then starts charging.

[0040] For the convenience of subsequent description, a right-handed XYZ coordinate system is defined from the perspective shown in Figure 2 . Among them, the X-axis is parallel to the length direction of the vehicle 4, the Y-axis is parallel to the width direction of the vehicle 4, and the Z-axis is parallel to the height direction of the vehicle 4. The electric energy transmitting platform 22, the electric energy receiving platform 32 and the vehicle 4 share the same right-handed coordinate system. The positive direction of the X-axis described below refers to the direction pointed by the arrow of the X-axis, and the negative direction of the X-axis refers to the direction opposite to the positive direction of the X-axis. The positive and negative directions of the remaining Y-axis and Z-axis are the same by analogy and will not be elaborated here one by one.

[0041] The electric energy transmitting platform 22 has a first state and a second state. When the electric energy transmitting platform 22 is in the first state, the electric energy transmitting platform 22 is not in contact with the electric energy receiving platform 32 and is not charging. At this time, the height of the electric energy transmitting platform 22 is the first height. When the electric energy transmitting platform 22 is in the second state, the electric energy transmitting platform 22 abuts against the electric energy receiving platform 32 on the vehicle 4, and the electric energy transmitting platform 22 is used to transmit electric energy to the vehicle 4 through the electric energy receiving platform 32. At this time, the height of the electric energy transmitting platform 22 is the second height. Among them, the first height is greater than the second height. That is to say, when not charging, the height of the electric energy transmitting platform 22 is higher, and when charging, the electric energy transmitting platform 22 shrinks and the height is lower. It should be noted that the first height and the second height are the self-thicknesses of the electric energy transmitting platform 22 in the Z-axis direction.

[0042] In the related art, when the vehicle 4 is charging, the power transmission platform 22 and the power reception platform 32 are in a spaced state, that is, there is a gap between the power transmission platform 22 and the power reception platform 32. However, this form will result in a reduction in charging efficiency. Moreover, due to the existence of the gap, it is also necessary to prevent foreign objects or living bodies from entering the charging area during the charging process. Therefore, two auxiliary functions of foreign object detection and living body protection need to be added, which will increase the cost and technical complexity.

[0043] However, when the power transmission platform 22 provided by the present application is charging, the power transmission platform 22 and the power reception platform 32 are in contact with each other, so that the gap between the power transmission platform 22 and the power reception platform 32 can be avoided, thereby improving the charging efficiency. Moreover, it is not necessary to add the two functions of foreign object detection and living body protection, thus saving costs.

[0044] It should be noted that during the process of the vehicle 4 driving into the garage and when the power reception platform 32 is not in contact with the power transmission platform 22, the first height of the power transmission platform 22 is higher than the height of the power reception platform 32 from the ground.

[0045] The power transmission platform 22 itself has pressure elasticity. The so-called pressure elasticity means that when the power transmission platform 22 is subjected to a pressure towards the ground, the power transmission platform 22 is compressed and its height decreases (the height at this time is less than the first height). When the pressure is withdrawn, the power transmission platform 22 automatically returns to the first height. Due to the pressure elasticity of the power transmission platform 22, the power transmission platform 22 and the power reception platform 32 in the charging state can always be in a close contact state, so that the charging efficiency can be ensured not to decrease.

[0046] It can be understood that the chassis heights of different types of vehicles 4 may be different. Therefore, the heights of the power reception platforms 32 installed on the chassis from the ground are also different. When the power reception platforms 32 on different types of vehicles 4 are in contact with the power transmission platform 22, the compression degrees of the power transmission platform 22 are different. That is to say, the above-mentioned second height can be a non-fixed value.

[0047] Please refer to Figure 4, the electric energy transmitting platform 22 includes a housing 110, a telescopic sleeve 120 and a transmitting device 130 which are connected to each other. The housing 110 and the telescopic sleeve 120 jointly enclose a receiving space. The receiving space is used to receive the transmitting device 130. The transmitting device 130 is used to transmit electric energy to the electric energy receiving platform 32. The telescopic sleeve 120 is connected to the ground. The housing 110 is connected to one end of the telescopic sleeve 120 away from the ground. The housing 110 is used to abut against the electric energy receiving platform 32. When the electric energy transmitting platform 22 switches from the first state to the second state, the housing 110 is abutted by the electric energy receiving platform 32, and the height of the telescopic sleeve 120 gradually decreases. It can be understood that the setting form of connecting the housing 110 and the telescopic sleeve 120 enables the electric energy transmitting platform 22 to simultaneously achieve the functions of abutting, telescoping, and protecting the transmitting device 130, and has a simple structure and low manufacturing cost.

[0048] In one implementation, the telescopic sleeve 120 itself has compression elasticity, that is, the electric energy transmitting platform 22 realizes the mutual switching between the first height and the second height through the telescopic sleeve 120. In another implementation, the electric energy transmitting platform 22 may further include an elastic structure with compression elasticity. The elastic structure is arranged in the receiving space jointly enclosed by the housing 110 and the telescopic sleeve 120, and the elastic structure is connected to the housing 110. When the electric energy transmitting platform 22 switches from the first state to the second state, the elastic structure is compressed by the housing 110. When the electric energy transmitting platform 22 switches from the second state to the first state, the elastic structure provides an elastic force to the housing 110. In other words, when the electric energy receiving platform 32 applies a pressure towards the ground to the housing 110, the housing 110 compresses the elastic structure, and when the pressure is removed, the elastic structure drives the housing 110 away from the ground. Of course, there may be other feasible implementations, which will not be elaborated one by one here.

[0049] Please refer to Figure 5, a feasible implementation form of the telescopic sleeve 120 is introduced below: The telescopic sleeve 120 is generally wavy, and the telescopic sleeve 120 includes a plurality of deformation parts 121. The plurality of deformation parts 121 are connected in sequence. Each deformation part 121 is generally V-shaped. Each deformation part 121 includes a first side wall 1211 and a second side wall 1212. An included angle α is formed between the adjacent first side wall 1211 and the second side wall 1212. During the process of the power transmission platform 22 transitioning from the first state to the second state, the included angle α gradually decreases. During the process of the power transmission platform 22 transitioning from the second state to the first state, the included angle α gradually increases. It can be understood that since an included angle α is formed between the adjacent first side wall 1211 and the second side wall 1212, there is a space between the first side wall 1211 and the second side wall 1212, and this space allows the adjacent first side wall 1211 and the second side wall 1212 to move relative to each other. Overall, it is reflected that the telescopic sleeve 120 can be compressed or extended in the Z-axis direction. Of course, the telescopic sleeve 120 can also be in other structural forms, which will not be elaborated one by one here.

[0050] Please refer to Figure 4 , the housing 110 includes a connected abutting part 113 and a first guiding part 111. The upper surface of the abutting part 113 is parallel to the ground. The abutting part 113 is used to abut against the power receiving platform 32 in the second state. The first guiding part 111 is inclined relative to the ground, and the end of the first guiding part 111 away from the abutting part 113 is closer to the ground than the end of the first guiding part 111 connected to the abutting part 113. The first guiding part 111 is used to abut against the power receiving platform 32 during the process of transitioning from the first state to the second state to guide the power receiving platform 32 to the abutting part 113. The height from the end of the first guiding part 111 away from the abutting part 113 to the ground is less than the height from the power receiving platform 32 on the vehicle 4 to the ground, and the height from the end of the first guiding part 111 connected to the abutting part 113 to the ground is greater than the height from the power receiving platform 32 on the vehicle 4 to the ground. Please refer to Figures 6 to 9 , during the process of the vehicle 4 entering the garage and parking, the power receiving platform 32 first abuts against the first guiding part 111 and then gradually approaches the abutting part 113. Due to the inclined setting of the first guiding part 111, the self-height of the power transmission platform 22 gradually decreases from the first height. When the power receiving platform 32 abuts against the abutting part 113, the self-height of the power transmission platform 22 changes to the second height. It can be understood that different types of vehicles 4 with different chassis heights can compress the power transmission platform 22 through the first guiding part 111 and then achieve charging. Therefore, the setting of the first guiding part 111 expands the applicable range of the power transmission platform 22.

[0051] Please refer to Figure 4 , the power transmission platform 22 further includes a guiding member 140, and the guiding member 140 is detachably connected to a side of the first guiding portion 111 away from the abutting portion 113. The guiding member 140 is inclined with respect to the ground, and an end of the guiding member 140 away from the first guiding portion 111 is closer to the ground than an end of the guiding member 140 connected to the first guiding portion 111. The guiding member 140 is configured to abut against the power receiving platform 32 during the process of transitioning from the first state to the second state, so as to guide the power receiving platform 32 to the first guiding portion 111. It can be understood that the chassis of some vehicles 4 is very low (such as sports cars). Correspondingly, the distance from the power receiving platform 32 on the vehicle 4 to the ground is very small, resulting in the power receiving platform 32 being unable to touch the lowest point of the first guiding portion 111, and thus unable to achieve charging. The guiding member 140 provided in this embodiment is used to solve the problem of the low chassis of the vehicle 4. The guiding member 140 can guide the power receiving platform 32 to the first guiding portion 111, then abut against the abutting portion 113, and finally achieve charging. Moreover, the guiding member 140 is detachably connected to the abutting portion 113, so different types of guiding members 140 can be used for different types of vehicles 4. That is to say, the detachable connection setting form further expands the application range of the power transmission platform 22.

[0052] Please refer to Figure 10 , the housing 110 further includes a second guiding portion 112, and the second guiding portion 112 is connected to a side of the abutting portion 113 away from the first guiding portion 111. An end of the second guiding portion 112 away from the abutting portion 113 is closer to the ground than an end of the second guiding portion 112 connected to the abutting portion 113. The second guiding portion 112 is configured to abut against the power receiving platform 32 during the process of transitioning from the first state to the second state, so as to guide the power receiving platform 32 to the abutting portion 113. The second guiding portion 112 may be, but is not limited to, an arc-shaped structure.

[0053] It can be understood that during the process of the vehicle 4 entering the warehouse, an over-positioning situation may occur. The so-called over-positioning means that in the negative direction of the X-axis, the power receiving platform 32 on the vehicle 4 has passed over the power transmission platform 22, resulting in the power transmission platform 22 and the power receiving platform 32 not being fully aligned. If the over-positioning situation is serious, it will lead to a significant reduction in charging efficiency or even inability to charge. Please refer to Figures 11 to 14, in this embodiment, the second guiding portion 112 is provided to solve the problem of over-positioning. When the vehicle 4 is over-positioned, the vehicle 4 can reverse. During the reverse process, the power receiving platform 32 first abuts against the second guiding portion 112 and gradually approaches the abutting portion 113, while the self-height of the power transmitting platform 22 gradually decreases until the power receiving platform 32 contacts the abutting portion 113. Therefore, the setting of the second guiding portion 112 can avoid the problem of too low charging efficiency.

[0054] Optionally, in the direction of the telescopic sleeve 120 towards the housing 110 (the positive direction of the Z axis), the abutting portion 113 protrudes from the emitting device 130. Since the abutting portion 113 protrudes from the emitting device 130, when the power receiving platform 32 and the power transmitting platform 22 abut against each other, the abutting relationship is formed between the abutting portion 113 and the power receiving platform 32, rather than the emitting device 130. It can be understood that this setting form is beneficial to protecting the emitting device 130 from being damaged.

[0055] Please refer to Figure 15 , the power transmitting platform 22 further includes a cover plate 150 connected to the abutting portion 113 of the housing 110. The cover plate 150 can be, but is not limited to, a material such as plastic that does not affect the charging effect. The cover plate 150, the housing 110 and the telescopic sleeve 120 jointly enclose the receiving space. The cover plate 150 has an opening 151, and the opening 151 communicates with the receiving space. The emitting device 130 is exposed to the outside from the opening 151. It can be understood that exposing the emitting device 130 from the opening 151 can avoid weakening the magnetic field generated by the power transmitting platform 22, thereby ensuring a high charging efficiency between the power transmitting platform 22 and the power receiving platform 32.

[0056] In one embodiment, in the direction of the telescopic sleeve 120 towards the housing 110 (the positive direction of the Z axis), the abutting portion 113 protrudes from the cover plate 150, so as to ensure that the cover plate 150 is not abutted by the power receiving platform 32, thereby protecting the emitting device 130. Optionally, the height difference between the surface of the abutting portion 113 far from the telescopic sleeve 120 and the surface of the cover plate 150 far from the telescopic sleeve 120 is less than or equal to 1 mm, specifically, it can be 0.2 mm, 0.25 mm, 0.31 mm, 0.43 mm, 0.5 mm, etc.

[0057] In another embodiment, the surface of the abutting portion 113 away from the telescopic sleeve 120 and the surface of the cover plate 150 away from the telescopic sleeve 120 are flush with each other. It can be understood that since the surfaces of the two are flush, when the power receiving platform 32 and the power transmitting platform 22 are abutted, the cover plate 150 and the abutting portion 113 are simultaneously abutted against the power receiving platform 32. Compared with only the abutting portion 113 being abutted against the power receiving platform 32, the flush setting form can increase the abutting area between the power transmitting platform 22 and the power receiving platform 32, thereby reducing the acting force per unit area, and further being beneficial to protecting the power transmitting platform 22 and the power receiving platform 32.

[0058] Optionally, the opening 151 includes a first opening 1511 and a second opening 1512 which are arranged at intervals. The size of the first opening 1511 is 10 cm × 10 cm. The area size of the transmitting device 130 exposed from the first opening 1511 is 10 cm × 10 cm. The size of the second opening 1512 is 10 cm × 10 cm. The area size of the transmitting device 130 exposed from the second opening 1512 is 10 cm × 10 cm. In the related art, the area size of the transmitting device 130 exposed from the first opening 1511 is 2.5 cm × 2.5 cm, and the area size of the transmitting device 130 exposed from the second opening 1512 is 2.5 cm × 2.5 cm. In the case where the area size is set to 2.5 cm × 2.5 cm, the charging requirement can be satisfied. In this embodiment, the above area size is set to 10 cm × 10 cm, so that the vehicle 4 can have a parking deviation relative to the power transmitting platform 22. That is to say, even after the vehicle 4 stops in the garage and there is a deviation of the power transmitting platform 22 relative to the power transmitting platform 22 in the X-axis or Y-axis direction, the charging requirement can be satisfied.

[0059] Please refer to Figure 10 , the first control device 21 can be electrically connected to the transmitting device 130 of the power transmitting platform 22 through a cable 160 provided with a connector. A notch 114 can be provided on the housing 110 of the power transmitting platform 22, and the connector passes through the notch 114 and is connected to the transmitting device 130. The housing 110 can further include a protective cover 170, and the protective cover 170 is connected to the housing 110 and covers the notch 114, so as to protect the connector.

[0060] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application, and these improvements and refinements are also regarded as the protection scope of the present application.
