[0027] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0028] The utility model is implemented as follows Figures 1 to 6As shown in the figure, a tablet computer protective cover with a keyboard includes a keyboard assembly 1 and a protective cover body 2 for accommodating a tablet computer 100; the keyboard assembly 1 includes a first substrate 11, a keyboard body 12 and a positioning bracket 13 arranged on the first substrate 11, and the positioning bracket 13 is provided with an electrical connection terminal 3 electrically connected to the keyboard body 12; the bottom edge of the protective cover body 2 is detachably connected to the first substrate 11 through the positioning bracket 13; an electrical connection male head 4 is provided on one side edge of the protective cover body 2, and an electrical connection contact 5 electrically connected to the electrical connection male head 4 is provided on the bottom edge of the protective cover body 2, the electrical connection contact 5 corresponds to the electrical connection terminal 3, and the electrical connection terminal 3 is electrically connected to the electrical connection male head 4 through the electrical connection contact 5.

[0029] In this embodiment, the protective cover body 2 includes a second substrate 21, and the left and right sides of the second substrate 21 are correspondingly provided with a panel 22, and a receiving cavity for receiving the tablet computer 100 is formed between the panels 22 on the left and right sides and the front surface of the second substrate 21. Specifically, the bottom ends of the panels 22 on the left and right sides extend to the right and left along the bottom side of the second substrate 21, and the bottom ends of the two panels 22 are opposite to each other and form a first gap. The top ends of the panels 22 on the left and right sides extend to the right and left along the top side of the second substrate 21, and the top ends of the two panels 22 are opposite to each other and form a second gap for receiving the tablet computer stylus.

[0030] The size of the receiving cavity is adapted to the tablet computer 100; for example, if the tablet computer 100 is 11 inches in size, the size of the receiving cavity corresponds thereto; if the tablet computer 100 is 12.9 inches in size, the size of the receiving cavity also corresponds thereto. Therefore, the size of the tablet computer protective cover with keyboard in this embodiment should be adjusted according to the size of different tablet computers 100, and the specific size should be based on actual application.

[0031] In this embodiment, the electrical connector 4 is disposed in the middle of the enclosure 22 on the right side of the second substrate 21. The electrical connector 4 is a TPYE-C male connector, and the electrical connection terminal 3 is a Pogopin. Both the TPYE-C male connector and the Pogopin have the characteristics of stable connection and fast response, and are widely used. The electrical connection contact 5 is a metal contact.

[0032] Furthermore, a base 23 perpendicular to the second substrate 21 is provided in the first interval, and the base 23 is plug-fitted and connected with the positioning bracket 13. Specifically, a through hole communicating with the interior of the base 23 is provided in the middle of the bottom surface, and the electrical connection contact 5 is exposed on the bottom surface of the base 23 through the through hole. The electrical connection contact 5 is provided on a first FPC (Flexible Printed Circuit) board (not shown in the drawings), and the FPC board (not shown in the drawings) is provided inside the base 23 and the enclosure 22.

The FPC board has good stability and flexibility. According to the positional relationship between the base 23 and the enclosure 22, the FPC board (not shown in the drawings) can be adaptively arranged inside the base 23 and the enclosure 22, so that a stable electrical connection relationship is established between the electrical connection contact 5 and the electrical connection male head 4.

[0033] In this embodiment, the length of the second interval is based on the length that can accommodate the tablet computer stylus. Since the four diagonals of the tablet computer 100 are usually set as arcs, the upper and lower ends of the left and right side panels 22 are also curved at the transition to arcs, which is more beautiful.

[0034] Furthermore, the positioning bracket 13 includes a positioning bar 131 and a first connecting member 132 connected to the positioning bar 131, and the first connecting member 132 is also connected to the first substrate 11.

In actual application, you can refer to the existing technology and will not go into details in this embodiment.

[0036] The top surface of the positioning strip 131 is provided with positioning bosses 1311 on both sides of the electrical connection terminal 3, and the bottom surface of the base 23 is provided with positioning holes 231 for inserting the positioning bosses 1311 at positions corresponding to the positioning bosses 1311. The positioning bosses 1311 are truncated cone-shaped. The size of the positioning hole 231 is adapted to the positioning bosses 1311, so that the plug-in connection is more secure, thereby playing a role of stable support.

[0037] Furthermore, a backing plate 6 is provided at the upper position of the rear surface of the second substrate 21, and a second connecting member 60 is provided at the bottom edge of the backing plate 6. The backing plate 6 is rotatably connected to a support plate 7 that is flipped relative to the second substrate 21 through the second connecting member 60. A third connecting member 61 is provided at the top edge of the backing plate 6. The backing plate 6 is connected to a magnetic buckle plate 8 through the third connecting member 61.

[0038] The first connecting member 132, the second connecting member 60 and the third connecting member 61 can all be flexible leather case connecting pieces commonly used in the prior art protective leather cases. The pad 6 and the support plate 7 can also be molded by wrapping the leather case, and are integrally connected with the corresponding second connecting member 60 and the third connecting member 61 to form an integrated structure, so that the pad 6 and the support plate 7 can be smoothly turned over with each other. This is a prior art and is not specifically limited in this embodiment.

[0039] In other embodiments, the third connecting member 61 is a rotating shaft, and the pad 6 and the support plate 7 are connected as one body via the rotating shaft, which can make the supporting force of the support plate 7 more stable.

[0040] In other embodiments, the electrical connector 4 and the electrical connection terminal 3 may be electrically connected via a wire, and accordingly, the interior of the protective cover body 2 should be provided with a channel for wiring.

[0041] When assembling the tablet computer 100, the tablet computer 100 is fixed in the receiving cavity by the enclosures 22 on the left and right sides of the second substrate 21, and the charging port on the tablet computer 100 is plugged into the electrical connector 4 to achieve electrical connection. The charging port on the tablet computer 100 is a TYPE-C female connector.

[0042] Furthermore, a magnetic sheet (not shown in the drawings) for magnetically attracting a tablet computer stylus pen should be provided on the side of the tablet computer 100 at a position corresponding to the second interval. Specifically, the magnetic sheet (not shown in the drawings) can be provided at a corresponding position on the inner side wall of the tablet computer 100 shell.

[0043] In this embodiment, the 11-inch keyboard body 12 can be compatible with an 11-inch or 10.9-inch tablet computer 100. This is only an example and does not limit the model of the tablet computer 100. The actual application shall prevail.
