Description

Technical Field

[0001] This disclosure relates to the field of battery technology, and in particular to a battery antenna cover and battery pack. Background Technology

[0002] With the development of battery technology, some battery packs come with built-in antenna modules and GPS modules, which are mainly used for the positioning, tracking and location confirmation of vehicles or objects to inform users of the current battery pack status information.

[0003] In existing technologies, some battery packs use a metal casing, with the antenna module and GPS module installed inside. This means the signal is shielded by the metal casing, preventing the antenna and GPS modules from receiving signals properly, thus hindering the battery pack's location. Furthermore, to more effectively determine the battery pack's precise location, i.e., the location of the electric vehicle or energy storage device, the antenna and GPS modules are typically mounted on the outside of the battery's metal casing. However, this method of placing the devices on the outside of the battery's metal casing has certain drawbacks, easily leading to the loss of the antenna module and / or GPS module. Specifically, the reasons for loss may include, but are not limited to, malicious removal or external impact. These problems reduce the reliability of battery pack signal reception and location tracking. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a battery antenna cover and battery pack that ensures normal positioning and prevents the loss of antenna module and GPS module.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: Please see Figures 1 to 4The battery antenna cover 10 of this utility model includes a metal cover body 100, a plastic antenna top cover 200, a positioning and communication component 300, and a waterproof ring 400. The metal cover body 100 has an installation opening 101. The plastic antenna top cover 200 is connected to the metal cover body 100 and blocks the installation opening 101. The plastic antenna top cover 200 has an antenna mounting area 201 and a GPS mounting area 202, which are located on the same side of the plastic antenna top cover 200. The positioning communication component 300 includes an antenna module 310 and a GPS module 320. The antenna module 310 is installed in the antenna mounting area 201, and the GPS module 320 is installed in the GPS mounting area 202, so that the antenna module 310 and the GPS module 320 are located on the inner side of the plastic antenna top cover 200. The metal top cover body 100 has a mounting groove 103, and the opening of the mounting groove 103 faces the plastic antenna top cover 200. A waterproof ring 400 is located in the mounting groove 103, and the waterproof ring 400 is press-fitted with the plastic antenna top cover 200. It can be understood that since the plastic antenna top cover 200 is made of plastic, when there is an external signal input, the signal will be reflected back when it encounters the metal component. However, since the antenna module 310 and the GPS module 320 are installed on the plastic antenna top cover 200, the external signal can be received by the antenna, thereby ensuring the positioning reliability of the battery pack. Furthermore, the antenna module 310 and the GPS module 320 are located on the inner wall of the plastic antenna top cover 200.

[0023] In the above embodiments, the battery antenna cover 10 uses a metal cover body 100 and a plastic antenna top cover 200. The antenna module 310 and GPS module 320 are both installed on the inner wall of the plastic antenna top cover 200. This ensures that the antenna module 310 can receive signals normally when the battery pack is used, and that the GPS module 320 can send data for proper positioning. When the battery antenna cover 10 is used in the battery pack, the antenna module 310 and GPS module 320 are positioned facing the battery module, meaning they are installed inside the entire battery pack. This protects the antenna module 310 and GPS module 320 from loss due to external interference such as malicious removal or impact, ensuring the reliability of signal reception by the battery pack's positioning communication component 300 and the battery pack's positioning and tracking. In other words, the antenna module 310 and GPS module 320 are located inside the entire battery pack, allowing the battery pack to protect them from loss. In addition, this solution adds a waterproof ring 400. After connecting the metal top cover body 100 and the plastic antenna top cover 200, the waterproof ring 400 abuts against the metal top cover body 100 and the plastic antenna top cover 200 respectively, thereby ensuring the waterproof performance of the battery pack.

[0024] like Figure 4 and Figure 5 As shown, in one embodiment, the battery antenna cover 10 further includes a plurality of locking members 500. The metal cover body 100 has a plurality of first screw holes 102, and the plastic antenna top cover 200 has a plurality of second screw holes 203. The threaded portion of each locking member 500 passes through the corresponding first screw hole 102 and second screw hole 203 in sequence, and the top of each locking member abuts against the metal cover body 100, so that the cover assembly and the plastic antenna top cover 200 are fastened together by the locking member 500. Further, the locking member 500 is a machine screw.

[0025] Furthermore, such as Figures 3 to 5 As shown, the waterproof ring 400 has multiple through holes 401, and the threaded portion of a locking member 500 is sequentially inserted into the corresponding first screw hole 102, through hole 401, and second screw hole 203. In this embodiment, the metal top cover body 100 and the plastic antenna top cover 200 are abutted together by the waterproof ring 400, and then locked together, so that the top cover assembly and the waterproof ring 400, and the waterproof ring 400 and the plastic antenna top cover 200 are locked together by the locking member 500. This prevents moisture or dust from entering the battery pack from the gap between the metal top cover body 100 and the plastic antenna top cover 200, ensuring the waterproof performance between the metal top cover body 100 and the plastic antenna top cover 200, and preventing water or dust from entering the battery pack, which would affect the battery pack's positioning and communication performance.

[0026] Furthermore, such as Figure 3 , Figure 6 , Figure 7 and Figure 9 As shown, the waterproof ring 400 includes a transition portion 410 and multiple connecting portions 420. The multiple connecting portions 420 are connected to the transition portion 410. Each through hole 401 is located in the corresponding connecting portion 420. The mounting groove 103 includes a transition groove 1031 and multiple connecting grooves 1032. The multiple connecting grooves 1032 are all connected to the transition groove 1031. Each first screw hole 102 is located in the corresponding connecting groove 1032 and is connected to the connecting groove 1032. Each connecting portion 420 is located in the corresponding connecting groove 1032, and the transition portions 410 are all located in the transition groove 1031. In this embodiment, since the transition portion 410 is located in the transition groove 1031 and each connecting portion 420 is located in the corresponding connecting groove 1032, the waterproof ring 400 is located entirely within the groove, which serves as a limit to prevent the waterproof ring 400 from shifting or even moving when assembling the battery antenna cover 10. This ensures the waterproof performance of the assembled battery pack and also avoids the battery pack antenna receiving signal and / or positioning reliability being affected by water ingress.

[0027] Furthermore, such as Figure 4 , Figure 5 and Figure 8 As shown, the plastic antenna top cover 200 is provided with a screw protrusion 210, and a second screw hole 203 is opened in the screw protrusion 210. The threaded part of the locking member 500 is located in the second screw hole 203 of the screw protrusion 210 and is connected to the screw protrusion 210. Thus, the plastic antenna top cover 200, the waterproof ring 400 and the metal top cover body 100 are connected by the locking member 500.

[0028] like Figures 4 to 7 As shown, in one embodiment, the metal top cover body 100 is provided with a small protrusion 110, which is disposed on the side wall of the mounting cover opening 101. One side of the small protrusion 110 forms a signal reflection gap with the antenna mounting area 201. It can be understood that by providing the small protrusion 110, on the one hand, the metal surface of the metal top cover body 100 is kept at a certain distance from itself, and the antenna module 310 is also kept at a certain distance from the small protrusion 110. This greatly reduces the interference of the metal surface on the antenna magnetic field area, creating basic conditions for the antenna to work efficiently. On the other hand, the small protrusion 110 reflects electromagnetic waves, gathers signal energy and guides it to radiate outward, and is then received by the antenna module 310, thereby improving the signal strength in a specific direction to a certain extent. Furthermore, when some electromagnetic waves are radiated from the small protrusion 110, since the plastic antenna top cover 200 is made of plastic, plastic does not have the conditions for reflection or absorption, so the electromagnetic waves can be radiated through the plastic antenna top cover 200 so that the user can obtain the current status information of the battery pack.

[0029] Furthermore, the small protrusion 110 is a metal protrusion, which is used to receive external signals and bounce them back to the antenna module 310.

[0030] like Figure 8 As shown, in one embodiment, the plastic antenna top cover 200 is provided with a mounting ring 220, which is located around the periphery of the GPS mounting area 202 to better install the GPS module 320 and prevent the GPS module 320 from moving on its own.

[0031] like Figure 6 and Figure 8 As shown, in one embodiment, the metal top cover body 100 has multiple first limiting grooves 105, and the plastic antenna top cover 200 has multiple first positioning posts 230 protruding from it. Each first positioning post 230 is located within a corresponding first limiting groove 105 to better fix the plastic antenna top cover 200 and prevent it from moving on its own. In this embodiment, the number of first limiting grooves 105 and first positioning posts 230 are both multiple and equal.

[0032] Furthermore, such as Figure 6 and Figure 8As shown, the metal top cover body 100 has multiple second positioning posts 120 protruding from it, and the plastic antenna top cover 200 has multiple limiting protrusions 240 protruding from it. Each limiting protrusion 240 has a second limiting groove 241, and each second positioning post 120 is located in the corresponding second limiting groove 241 to better fix the plastic antenna top cover 200 and prevent the plastic antenna top cover 200 from moving on its own. In this embodiment, the number of second positioning posts 120 and second limiting grooves 241 are both multiple and equal.

[0033] It is understood that each first positioning post 230 is located within a corresponding first limiting groove 105, and each second positioning post 120 is located within a corresponding second limiting groove 241. When the first positioning post 230 abuts against the bottom of the first limiting groove 105, and the second positioning post 120 abuts against the bottom of the second limiting groove 241, in addition to fixing the plastic antenna top cover 200, it also limits the compression of the waterproof ring 400, preventing excessive compression that could damage the waterproof ring 400, thus avoiding the failure of waterproof performance due to damage to the waterproof ring 400. In this embodiment, the second positioning post 120 and the connecting groove 1032 are alternately distributed around the mounting cover opening 101, and the limiting protrusion 240 and the screw-in protrusion 210 are alternately arranged.

[0034] This disclosure also provides a battery pack, including a battery module, a housing, and a battery antenna cover 10 according to any embodiment. The battery module is located inside the housing, and the battery antenna cover 10 is connected to the end of the housing. The positioning communication component 300 of the battery antenna cover 10 is disposed facing the battery module.

[0035] Compared with the prior art, this disclosure has at least the following advantages: The aforementioned battery antenna cover 10 comprises a metal cover body 100 and a plastic antenna top cover 200. The antenna module 310 and GPS module 320 are both installed on the inner wall of the plastic antenna top cover 200. This ensures that the antenna module 310 can receive signals normally when the battery pack is used, enabling the GPS module 320 to send data for proper positioning. When the battery antenna cover 10 is used in the battery pack, the antenna module 310 and GPS module 320 are positioned facing the battery module, meaning they are installed within the entire battery pack. This protects the antenna module 310 and GPS module 320 from external interference such as malicious removal or impact, preventing loss and ensuring the reliability of the battery pack's positioning communication component 300 in receiving signals and the battery pack's positioning and tracking capabilities. In addition, this solution adds a waterproof ring 400. After connecting the metal top cover body 100 and the plastic antenna top cover 200, the waterproof ring 400 abuts against the metal top cover body 100 and the plastic antenna top cover 200 respectively, thereby ensuring the waterproof performance of the battery pack.

[0036] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
