Description

Technical Field

[0001] The present invention relates to the technical field of battery boxes, and in particular to a transportation tool, a battery box and an installation structure of an external antenna thereof. Background Art

[0002] With the rise of new energy technologies, transportation vehicles that use electricity as a driving energy source are becoming increasingly popular. In order to monitor the working condition of the battery in real time to facilitate the work of the power distribution manager, the traditional approach is to set up an external antenna and use the external antenna to communicate wirelessly with the internal antenna in the battery to monitor the working condition of the battery. In the traditional approach, the external antenna cannot accurately cooperate with the internal antenna of the battery, resulting in the inability to reliably transmit the signal. Summary of the invention

[0003] Based on this, a mounting structure of a transportation tool, a battery box and an external antenna thereof is proposed. The mounting structure of the external antenna can enable the external antenna to accurately cooperate with the built-in antenna of the battery to ensure that the signal can be transmitted reliably; in this way, the battery box using the mounting structure of the external antenna can accurately monitor the working condition of the battery; in this way, the transportation tool using the battery box can operate reliably.

[0004] The technical solution is as follows:

[0005] On the one hand, a mounting structure for an external antenna is provided, comprising an antenna body and a box body, wherein the antenna body is fixedly mounted on the bottom wall of the box body, and the antenna body is provided with a first positioning portion, and the bottom wall of the box body is provided with a second positioning portion for positioning and cooperating with the first positioning portion, so that the antenna body is arranged correspondingly to the built-in antenna of the battery.

[0006] When the installation structure of the external antenna of the above-mentioned embodiment is used, the battery is installed in the installation cavity of the box body, and the first positioning part and the second positioning part are used to accurately and reliably fix the antenna body of the external antenna on the bottom wall of the box body, so that the antenna body of the external antenna can be set correspondingly with the built-in antenna of the battery to achieve cooperation, thereby ensuring that the signal between the external antenna and the built-in antenna can be reliably transmitted. Compared with the traditional method of fixing the external antenna on the mounting plate or frame of the distribution manager, the box body is selected as the common installation reference and positioning reference of the external antenna and the built-in antenna, which reduces the relative error when the external antenna and the built-in antenna are installed, so that the external antenna and the built-in antenna can be reliably set correspondingly and reliably achieve communication connection. In addition, compared with the traditional method of fixing the external antenna on the mounting plate of the distribution manager, the antenna body can be installed and fixed without the help of the mounting plate, which saves costs.

[0007] The technical solution is further described below:

[0008] In one embodiment, the antenna body includes a substrate and a communication coil disposed on the substrate, the substrate is provided with the first positioning portion, and when the first positioning portion is positioned and matched with the second positioning portion, the communication coil is disposed correspondingly to the built-in antenna.

[0009] In one of the embodiments, the mounting structure of the external antenna further includes a buffer, and the buffer is used to buffer the impact force exerted on the substrate.

[0010] In one embodiment, the base plate is detachably connected to the bottom wall of the box body.

[0011] In one embodiment, the first positioning portion is configured as a positioning hole, and the second positioning portion is configured as a positioning pin capable of being positioned and matched with the positioning hole.

[0012] On the other hand, a battery box is provided, comprising: the installation structure of the external antenna; and a battery, wherein the battery is arranged in the box body, the battery is provided with a built-in antenna, and the built-in antenna can be arranged corresponding to the antenna body.

[0013] When the battery box of the above embodiment is used, the battery is installed in the installation cavity of the box body, and the first positioning part and the second positioning part are used to accurately and reliably fix the antenna body of the external antenna on the bottom wall of the box body, so that the antenna body of the external antenna can be set correspondingly with the internal antenna of the battery to achieve cooperation, thereby ensuring that the signal between the external antenna and the internal antenna can be reliably transmitted. Compared with the traditional method of fixing the external antenna on the mounting plate or frame of the distribution manager, the box body is selected as the common installation reference and positioning reference for the external antenna and the internal antenna, which reduces the relative error when installing the external antenna and the internal antenna, so that the external antenna and the internal antenna can be reliably set correspondingly and reliably achieve communication connection, so that the working condition of the battery can be accurately monitored in real time.

[0014] In one of the embodiments, the battery box further includes a power distribution shell, the power distribution shell is provided with a power distribution cavity, the antenna body is arranged in the power distribution cavity, and the power distribution shell is sealed and matched with the box body.

[0015] In one of the embodiments, the box body is provided with an installation cavity for installing a battery, and the box body is also provided with a first guide portion for guiding the battery to be installed in the installation cavity.

[0016] In one embodiment, the number of the batteries is at least two, and each battery corresponds to one of the antenna bodies.

[0017] On the other hand, a transportation tool is provided, comprising the battery box.

[0018] Compared with the traditional method of fixing the external antenna of the battery box on the mounting plate or frame of the power distribution manager, the transportation vehicle in the above-mentioned embodiment selects the box body as the common installation reference and positioning reference of the external antenna and the internal antenna, thereby reducing the relative error when installing the external antenna and the internal antenna, so that the external antenna and the internal antenna can be reliably set to correspond and reliably realize communication connection, thereby ensuring the reliable operation of the transportation vehicle.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to restrict the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] The terms "first", "second", "third" and the like in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0031] It should also be understood that when interpreting an element, even if not explicitly described, the element is interpreted as including a range of error, which should be within the acceptable deviation range of the specific value determined by those skilled in the art. For example, "approximately", "approximately" or "substantially" can mean within one or more standard deviations, which are not limited here.

[0032] like Figures 1 to 4 As shown, in one embodiment, a mounting structure for an external antenna is provided, including an antenna body 100 and a box body 200, wherein the antenna body 100 is fixed to a bottom wall 210 of the box body 200, and the antenna body 100 is provided with a first positioning portion 111, and the bottom wall 210 of the box body 200 is provided with a second positioning portion 220 for positioning and cooperating with the first positioning portion 111, so that the antenna body 100 is arranged corresponding to the built-in antenna 310 of the battery 300.

[0033] When the external antenna installation structure of the above embodiment is used, the battery 300 is installed in the installation cavity 230 of the box body 200, and the first positioning portion 111 and the second positioning portion 220 are used to accurately and reliably fix the antenna body 100 of the external antenna on the bottom wall 210 of the box body 200, so that the antenna body 100 of the external antenna can be arranged correspondingly with the internal antenna 310 of the battery 300 to achieve cooperation, thereby ensuring that the signal between the external antenna and the internal antenna 310 can be reliably transmitted. Compared with the traditional method of fixing the external antenna on the mounting plate or frame of the power distribution manager, the box body 200 is selected as the common installation reference and positioning reference of the external antenna and the internal antenna 310, which reduces the relative error when the external antenna and the internal antenna 310 are installed, so that the external antenna and the internal antenna 310 can be reliably set correspondingly and reliably achieve communication connection. Furthermore, compared with the conventional method of fixing the external antenna on the mounting plate of the power distribution manager, the antenna body 100 can be installed and fixed without the aid of a mounting plate, thus saving costs.

[0034] It should be noted that the external antenna and the internal antenna 310 can be set as NFC (Near Field Communication, near-field wireless communication technology) antennas, which are low-cost and reliable in near-field communication. By using the corresponding settings and communication connection between the external antenna and the internal antenna 310 of the battery 300, the charging and discharging of the battery 300 can be intelligently controlled, the power of the battery 300 can be monitored in real time and corresponding prompt information can be issued, the password matching with the battery 300 can be achieved, the anti-theft performance can be improved, and the failure mode of the battery 300 can be monitored in real time and corresponding prompt information can be issued.

[0035] like Figure 4 As shown, in one embodiment, the antenna body 100 includes a substrate 110 and a communication coil 120 disposed on the substrate 110, and the substrate 110 is provided with a first positioning portion 111, and when the first positioning portion 111 is positioned and matched with the second positioning portion 220, the communication coil 120 is disposed correspondingly to the built-in antenna 310. In this way, when the substrate 110 is fixed on the bottom wall 210 of the box body 200, the positioning and matching of the first positioning portion 111 and the second positioning portion 220 are utilized, so that the communication coil 120 on the substrate 110 is disposed correspondingly to the coil of the built-in antenna 310, thereby enabling the external antenna to reliably achieve communication connection with the built-in antenna 310. The substrate 110 can be a plate made of ferrite material with anti-interference ability, and the communication coil 120 can be disposed on the substrate 110 by winding, printing or etching.

[0036] like Figure 3As shown, further, the mounting structure of the external antenna also includes a buffer 400, and the buffer 400 is used to buffer the impact force received by the substrate 110. In this way, the buffer 400 can be used to buffer and absorb the impact force between the substrate 110 and the box body 200, so as to prevent the substrate 110 from vibrating and deviating relative to the box body 200, thereby ensuring that the communication coil 120 on the substrate 110 can reliably achieve a corresponding setting with the coil of the built-in antenna 310 and reliably communicate and connect. The buffer 400 can be set as a rubber pad or a silicone pad, and the buffer 400 can be set at a corresponding position on the outer side of the substrate 110. The buffer 400 can be set on the bottom wall 210 of the box body 200 or the substrate 110 by bonding or clamping. The buffer 400 may be disposed between the substrate 110 and the box body 200 , or between the power distribution shell and the substrate 110 , or simultaneously between the substrate 110 and the box body 200 and between the power distribution shell and the substrate 110 , that is, the buffer 400 may be disposed on both the upper and lower sides of the substrate 110 .

[0037] like Figure 4 As shown, the substrate 110 is fixed to the bottom wall 210 of the box body 200, which can be achieved by a detachable connection (for example, by a clamping connection or a bolt connection), and it is sufficient to stably and reliably connect the substrate 110 to the box body 200. The substrate 110 is locked to the bottom wall 210 of the box body 200 by fasteners such as screws 130, and the impact force between the substrate 110 and the box body 200 is buffered and absorbed by the buffer 400, so that the assembly connection of the substrate 110 and the box body 200 can be stably and reliably achieved.

[0038] The positioning cooperation between the first positioning portion 111 and the second positioning portion 220 can be achieved by the plug-in cooperation of the positioning column and the positioning hole, or by the snap-in cooperation of the snap-in block and the snap-in slot, as long as it can enable the antenna body 100 and the box body 200 to be accurately assembled and connected.

[0039] In one embodiment, the first positioning portion 111 is configured as a positioning hole, and the second positioning portion 220 is configured as a positioning pin that can be positioned and matched with the positioning hole. In this way, the positioning of the antenna body 100 and the box body 200 can be simply and conveniently achieved by inserting the positioning pin into the positioning hole, thereby improving assembly efficiency. The positioning pin on the substrate 110 is inserted into the positioning hole, and the substrate 110 is fixed with the screw 130, so that the assembly connection between the substrate 110 and the box body 200 can be accurately and stably achieved.

[0040] like Figures 1 to 4As shown, in one embodiment, a battery box 10 is provided, including: a mounting structure for an external antenna of any of the above-mentioned embodiments; and a battery 300, wherein the battery 300 is disposed in a box body 200, and the battery 300 is provided with a built-in antenna 310, and the built-in antenna 310 can be disposed corresponding to the antenna body 100.

[0041] When the battery box 10 of the above embodiment is used, the battery 300 is installed in the installation cavity 230 of the box body 200, and the first positioning portion 111 and the second positioning portion 220 are used to accurately and reliably fix the antenna body 100 of the external antenna on the bottom wall 210 of the box body 200, so that the antenna body 100 of the external antenna can be arranged correspondingly with the internal antenna 310 of the battery 300 to achieve cooperation, thereby ensuring that the signal between the external antenna and the internal antenna 310 can be reliably transmitted. Compared with the traditional method of fixing the external antenna on the mounting plate or frame of the power distribution manager, the box body 200 is selected as the common installation reference and positioning reference of the external antenna and the internal antenna 310, which reduces the relative error when the external antenna and the internal antenna 310 are installed, so that the external antenna and the internal antenna 310 can be reliably set correspondingly and reliably achieve communication connection, so that the working condition of the battery 300 can be accurately monitored in real time.

[0042] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in one embodiment, the battery box 10 further includes a power distribution housing 500, the power distribution housing 500 is provided with a power distribution cavity 510, the antenna body 100 is arranged in the power distribution cavity 510, and the power distribution housing 500 is sealed with the box body 200. In this way, the power distribution housing 500 of the power distribution manager is sealed with the box body 200 to prevent the antenna body 100 of the external antenna from being corroded by foreign objects, and the protection performance is good. For example, the antenna body 100 can be prevented from being affected by rain or sand, ensuring that the battery box 10 can work stably and reliably. The sealing cooperation between the power distribution housing 500 and the box body 200 can be achieved by bolting or welding and adding a sealing ring.

[0043] like Figure 2 and Figure 4As shown, in one embodiment, the box body 200 is provided with an installation cavity 230 for installing the battery 300, and the box body 200 is also provided with a first guide portion (not shown) for guiding the battery 300 to be installed in the installation cavity 230. In this way, the first guide portion can be used to guide the battery 300 to smoothly enter the installation cavity 230, so that the battery 300 can be accurately installed and fixed in the installation cavity 230, and then the external antenna can be reliably and accurately set corresponding to the internal antenna 310 of the battery 300, so that the signal strength between the external antenna and the internal antenna 310 can be improved, and reliable signal transmission can be achieved between the external antenna and the internal antenna 310. The first guide portion can be set as a guide slope or a guide arc surface, as long as it can guide the battery 300 to enter the installation cavity 230.

[0044] In one embodiment, at least two batteries 300 are provided, and each battery 300 is provided with an antenna body 100. In this way, the working conditions of at least two batteries 300 can be monitored in real time. Among them, each battery 300 may correspond to a substrate 110 and an induction coil (i.e., one induction coil corresponds to one substrate 110), so that the coil of the built-in antenna 310 of the battery 300 is connected to the corresponding induction coil for communication; or all batteries 300 may correspond to one substrate 110, and the built-in antenna 310 of each battery 300 may correspond to one induction coil (i.e., one substrate 110 is provided with induction coils corresponding to the number of batteries 300).

[0045] In one embodiment, a transportation vehicle is provided, comprising the battery box 10 according to any one of the above embodiments.

[0046] Compared with the conventional method of fixing the external antenna of the battery box 10 on the mounting plate or frame of the power distribution manager, the transportation vehicle in the above-mentioned embodiment selects the box body 200 as the common installation reference and positioning reference of the external antenna and the internal antenna 310, thereby reducing the relative error when installing the external antenna and the internal antenna 310, so that the external antenna and the internal antenna 310 can be reliably set to correspond and reliably achieve communication connection, thereby ensuring the reliable operation of the transportation vehicle.

[0047] The transportation vehicle may be a car, an electric car, a motorcycle or other vehicles that can utilize the electric energy of the battery 300 as a driving energy source.

[0048] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0049] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as restrictions on the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
