[0002] A tablet computer, also called a portable computer, is a small and portable personal computer with a touch screen as the basic input device.

[0003] Most combined batteries of tablet computers have some disadvantages during use. For example, once the combined battery is installed in the tablet computer, it is not convenient for personnel to disassemble it. When the battery ages, its performance deteriorates or it malfunctions, users cannot replace the battery by themselves and must seek professional maintenance services or return it to the manufacturer for repair. This not only increases the complexity and time cost of repair, but also may lead to high repair costs. In view of this, we propose a detachable combined battery structure for a tablet computer. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a detachable combined battery structure for a tablet computer to solve the problems raised in the above background art.

The first protective shell and the second protective shell are closely attached to each other, and a combined battery body is arranged inside the first protective shell and the second protective shell;

[0007] A fixing component, which is located inside the first protective shell and is used to fix the first protective shell and the second protective shell;

[0008] A fixing plate, which is fixedly installed on the top of the second protective shell, and the fixing plate is inserted and matched with the tablet computer body. A second sliding groove is formed inside the fixing plate, and two limiting columns are symmetrically and slidably installed inside the second sliding groove. A fixing ring is fixedly installed on the limiting column, and the fixing ring is slidably connected with the second sliding groove. A tension spring is sleeved on the limiting column on one side of the fixing ring, and two ends of the tension spring are respectively fixed to the corresponding fixing ring and the inner wall of the second sliding groove. One end of the limiting column penetrates through the second sliding groove and extends into the tablet computer body, and one end of the limiting column is inserted and matched with the tablet computer body;

[0009] A driving component, which is located inside the fixing plate and is used to drive the four limiting columns to slide.

[0010] In this technical solution, when the combined battery body needs to be disassembled, through the provided driving component, then under the action of the pulling force of the four tension springs, the four fixing rings all slide towards the sliding plate. The four fixing rings respectively drive the four limiting posts to slide towards the sliding plate. When the four limiting posts all disengage from the tablet computer body, the fixing plate can be pulled to drive the first protective case and the second protective case to disengage from the tablet computer body. Through the provided fixing component, the first protective case and the second protective case can be separated, and finally the combined battery body can be taken out, with convenient and fast operation;

[0011] When the combined battery body needs to be installed, first place the combined battery body in the first protective case, then buckle the second protective case on the top of the first protective case. Through the provided fixing component, the first protective case and the second protective case are tightly connected. Then insert the first protective case, the second protective case and the fixing plate into the tablet computer body. Through the provided driving component, the four limiting posts can be driven to slide away from the sliding plate. At the same time, the four limiting posts respectively drive the four fixing rings to slide, and the four fixing rings respectively pull the four tension springs to elongate. Finally, the four limiting posts all insert into the tablet computer body, and the positions of the first protective case, the second protective case and the fixing plate can be fixed, ensuring that the combined battery body is conveniently installed and the installation operation is simple and fast.

[0012] In the above technical solution, further, the fixing component includes:

[0013] The third sliding groove, the third sliding groove is opened in the first protective case, and a sliding rod is slidably installed in the third sliding groove. A plurality of limiting blocks are fixedly installed at the top of the sliding rod. One side of the limiting block is fixedly installed with a first spring fixed to the third sliding groove, and the limiting block is slidably connected to the third sliding groove;

[0014] A plurality of limiting grooves, a plurality of the limiting grooves are all opened in the second protective case, and a plurality of the limiting grooves are all communicated with the third sliding groove. The upper end of the limiting block extends into the corresponding limiting groove, and the upper end of the limiting block is inserted and matched with the limiting groove.

[0015] In this technical solution, a person uses a SIM card ejector to poke the sliding rod. The sliding rod drives a plurality of limiting blocks to displace towards the sliding column. At the same time, a plurality of first springs are compressed and contracted. When the plurality of limiting blocks slide to a suitable position, the person pries the second protective case and the first protective case apart, and finally the combined battery body can be taken out, with convenient and fast operation;

[0016] When the combined battery body needs to be installed, first place the combined battery body in the first protective case, then buckle the second protective case on the top of the first protective case. At the same time, several limiting grooves will respectively squeeze several limiting blocks to slide towards the sliding column, and several first springs will be compressed and contracted. When the limiting blocks slide to the appropriate positions, the upper ends of the limiting blocks will enter the corresponding limiting grooves. Subsequently, under the action of the restoring force of several first springs, several limiting blocks will slide away from the sliding column, and then several limiting blocks will be respectively stuck in several limiting grooves, making the connection between the first protective case and the second protective case tight. Then insert the first protective case, the second protective case, and the fixing plate into the tablet computer body.

[0017] In the above technical solution, further, the driving assembly includes:

[0018] Two sliding plates, both of the two sliding plates are slidably installed in the second sliding groove and located between the four limiting columns. A threaded rod is rotatably installed at one end of the second sliding groove and within one of the sliding plates. One end of the threaded rod penetrates through the two sliding plates and extends to the outside, and the threaded rod is threadedly connected to the two sliding plates.

[0019] In this technical solution, when the combined battery body needs to be disassembled, first use a screwdriver to rotate the threaded rod forward. Under the action of the thread, the threaded rod drives the two sliding plates to slide. Subsequently, the two sliding plates no longer squeeze the four limiting columns. Under the pulling force of the four tension springs, the four fixing rings all slide towards the sliding plates, and the four fixing rings respectively drive the four limiting columns to slide towards the sliding plates. When all four limiting columns are disengaged from the tablet computer body, the fixing plate can be pulled to drive the first protective case and the second protective case to disengage from the tablet computer body;

[0020] Use a screwdriver to rotate the threaded rod in the reverse direction. Under the action of the thread, the threaded rod drives the two sliding plates to slide. Subsequently, the two sliding plates will respectively squeeze the four limiting columns to slide away from the sliding plates. At the same time, the four limiting columns respectively drive the four fixing rings to slide, and the four fixing rings respectively pull the four tension springs to elongate. Finally, all four limiting columns are inserted into the tablet computer body, and the positions of the first protective case, the second protective case, and the fixing plate can be fixed to ensure that the combined battery body is convenient to install, and the installation operation is simple and fast.

[0021] In the above technical solution, further, two first sliding grooves are opened in the first protective case. A sliding column is slidably installed in the first sliding groove.

The lower end of the sliding column is fixedly installed with a second spring fixed to the inner wall of the corresponding first sliding groove.

[0022] In this technical solution, under the action of the rebounding forces of the two second springs, the two sliding columns will slide upward and lift the second protective shell, and there is no need for personnel to use tools to pry open the second protective shell and the first protective shell anymore.

[0023] In the above technical solution, further, both sides of the sliding plate are inclined.

[0024] In this technical solution, it is ensured that the two sliding plates will respectively squeeze the four limiting columns to slide in a direction away from the sliding plates.

[0025] In the above technical solution, further, the upper end of the limiting block is inclined.

[0026] In this technical solution, it is ensured that several limiting blocks will be respectively stuck in several limiting grooves.

[0027] In the above technical solution, further, several of the limiting blocks are evenly distributed.

[0028] In this technical solution, it is ensured that the first protective shell and the second protective shell are tightly connected.

[0029] The beneficial effects of the present utility model are as follows:
