[0028] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0030] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.

[0031] Please see Figure 1 , Figure 2 and Figure 3 This application provides a tablet computer expansion protective case, including a protective case body 1 and a male-female integrated plug 2. The protective case body 1 has a cavity for accommodating the tablet computer inside. The side wall of the protective case body 1 has a through hole 101, the position of which is adapted to the position of the tablet computer's charging port. The male-female integrated plug 2 is fixedly disposed in the through hole 101. The male head 201 of the male-female integrated plug is located inside the protective case body 1, and the female head 202 of the male-female integrated plug is flush with the outer wall of the protective case body 1. A memory chip 3, a current controller 4, and a circuit connector 5 are embedded in the protective case body 1 at one end near the through hole 101. One end of the circuit connector 5 is electrically connected to the memory chip 3 and the current controller 4, the other end of the current controller 4 is electrically connected to the memory chip 3, and the other end of the circuit connector 5 is electrically connected to the male-female integrated plug 2.

[0032] Specifically, in the tablet computer expansion protective case provided in this application, the protective case body 1 is made of hard plastic or composite material, thereby protecting the tablet computer from external impacts, scratches, dust and other damage, while also improving the appearance and feel of the tablet computer.

[0033] Rigid plastics possess strong compressive strength and scratch resistance. Common rigid plastic materials include polycarbonate (PC) and polypropylene (PP). PC is a high-strength plastic with good impact resistance, effectively absorbing external forces and protecting tablets from damage. PP is a relatively lightweight and durable plastic with good toughness and abrasion resistance.

[0034] Composite materials are typically made by combining two or more different materials through specific processes, fully leveraging the advantages of each material and compensating for the shortcomings of a single material. Common composite materials include silicone and hard plastic composites, carbon fiber composites, and aluminum alloy composites. Silicone and hard plastic composites are commonly used in protective cases that combine soft and hard materials; the silicone portion provides good anti-slip and shock absorption, while the hard plastic portion enhances the structural strength and impact resistance of the case. Carbon fiber composites possess extremely high strength, heat resistance, and compressive strength, making protective cases made from this material very thin and sturdy, effectively protecting tablets from impacts without adding excessive weight. Aluminum alloy composites are widely used in protective cases, providing both good impact resistance and excellent heat dissipation.

[0035] Please see Figure 4 In the tablet computer expansion protective case provided in this application, the male and female integrated plug 2 is an integrated design. The male head 201 of the male and female integrated plug is used to connect to the charging port of the tablet computer 7, and the female head 202 of the male and female integrated plug is used to connect to the charger of the tablet computer 7, so that the tablet computer 7 can expand its storage capacity without affecting its normal charging.

[0036] Please see Figure 5 The male connector 201 of the male-female hybrid plug can be a USB or Lightning connector, and the corresponding female connector 202 can be a USB or Lightning interface. The USB connector is either Micro-B or Type-C, and the corresponding USB interface is also either Micro-B or Type-C, thus ensuring compatibility with all different tablet models currently on the market.

[0037] Specifically, in the tablet computer expansion protective case provided in this application, the storage chip 3 adopts a UFS (Universal Flash Memory) storage chip, which supports fast storage and read functions. It provides a read speed of up to 2900MB / s and a write speed of 1200MB / s, thereby meeting the user's high-performance storage needs; the storage chip has a capacity of 64GB to 2TB. In this application, the storage chip 3 is electrically connected to the tablet computer 7 through the current controller 4 and the male connector 201 of the male-female integrated plug. When the protective case is connected to the charging port of the tablet computer 7, the storage chip 3 communicates with the tablet computer through a data transmission protocol to realize the storage expansion function.

[0038] Specifically, in the tablet computer expansion protective case provided in this application, the current controller 4 can intelligently regulate the power and data flow between the storage chip 3 and the tablet computer, ensuring the stability of the expanded storage and tablet computer charging functions, and ensuring that the charging efficiency of the tablet computer is not affected while expanding storage. At the same time, the current controller 4 adopts an integrated IC module, further reducing the size of the expansion components and making the protective case thinner and lighter.

[0039] More specifically, in this application, the current controller 4 is a current controller based on the USB PD fast charging protocol. It supports the USB PD fast charging protocol to ensure power supply stability while expanding storage. The maximum charging power can reach 45W, ensuring the charging efficiency and safety of the tablet computer.

[0040] Continue reading Figures 1 to 3 The tablet computer expansion protective case provided in this application also includes a heat-conducting sheet 6, which is fixedly disposed between the storage chip 3 and the protective case body 1. The protective case body 1 has multiple heat dissipation holes at the position where the heat-conducting sheet 6 is fixed. The heat-conducting sheet 6 and the heat dissipation holes can effectively reduce the heat generated by the storage chip 3 during operation, prevent overheating, and thus ensure the long-term stable operation of the device.

[0041] Please see Figure 6 In the tablet computer expansion protective case provided in this application, a tablet computer stand 8 is also fixedly installed on the back of the protective case body 1, thereby supporting the tablet computer to be placed at multiple angles, making it convenient for users to use and enhancing the convenience and flexibility of the device.

[0042] In the tablet computer expansion protective case provided in this application, the protective case body 1, the male and female integrated plug 2, the storage chip 3, the current controller 4, the circuit connector 5 and the heat conduction sheet 6 are integrally formed, thereby achieving seamless cooperation with the tablet computer (PAD).
