[0013] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0014] In the following description, specific examples are given to provide a more in-depth understanding of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0015] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0016] To address the aforementioned technical problems, this application provides a tire pressure monitoring device, please refer to the appendix. Figure 1 To be continued Figure 7 The device includes a connection module and a display screen 1. The connection module consists of two locking parts 2, each with a connection structure. The rear surface of the display screen 1 housing is provided with a connecting seat 11, which is detachably connected to the connection structure, allowing the two locking parts 2 to be removed from the rear surface of the display screen 1 housing. The two locking parts 2 are also provided with grooves 211. The two locking parts 2 are detachably connected so that the grooves 211 of the two locking parts 2 are combined to form a mounting groove 21. Limiting structures are provided on both sides of the mounting groove 21. The detachable connection of the two locking parts 2 enables the mounting groove 21 to have the function of being opened. The end of the power plug 3 away from the power supply is provided with a first connector. When the tire pressure monitoring device is fixed by the power plug 3, the first connector is movably connected to the mounting groove 21. The limiting structure limits the first connector to the inner cavity of the mounting groove 21, so that the display screen 1 is fixed to the power supply by the power plug 3.

[0017] The fixing component is provided with a second connector. When the tire pressure monitoring device is fixed by the fixing component, the second connector is movably connected to the mounting groove 21. The limiting structure limits the second connector in the inner cavity of the mounting groove 21, so that the display screen 1 is fixed on the flat surface inside the vehicle through the fixing component.

[0018] Because the display screen 1 is movably connected to the power plug 3 or the fixing component through two locking parts 2, the display screen 1 can rotate at a large angle on the power plug 3 or the fixing component, allowing the user to adjust the angle of the display screen 1 according to their habits, thus improving the driving experience.

[0019] Because the two locking parts 2 limit the first connecting part or the second connecting part in the inner cavity of the mounting groove 21 through the limiting structure, the first connecting part or the second connecting part has a larger range of motion, which increases the rotatable angle of the display screen 1.

[0020] Because the two locking parts 2 are detachably connected, and the two locking parts 2 are detachably connected to the connector 11 of the display screen 1 through the connecting structure, the first connector of the power plug 3 and the second connector of the fixing component can be removed from the inner cavity of the mounting slot 21. Users can choose the fixing method of the tire pressure monitoring device according to the specific road conditions or habits, which meets the different needs of customers in different usage scenarios.

[0021] The rear surface of the casing of the display screen 1 is provided with a power cord 12, and the power plug 3 is provided with a power interface 31. When the tire pressure monitoring device is fixed by the power plug 3, the display screen 1 is detachably connected to the power interface 31 of the power plug 3 via the power cord 12. When the tire pressure monitoring device is fixed by the fixing component, the power cord 12 is connected to the external power interface 31. This avoids the need for a larger cable tray to accommodate the power cord 12 due to the built-in power cord 12, and also avoids damage to the built-in power cord 12 due to repeated screen rotation. Furthermore, the external power cord 12 allows users to use an adapter cable to adapt to the user's power interface 31 or use an extension cable to extend the power cord 12, thus improving the user experience.

[0022] In this embodiment, the first connector includes a connecting post 5 and a ball 6. The ball 6 is fixed to the power plug 3 by the connecting post 5. The second connector has the same structure as the first connector, which makes the display screen 1 have smoother rotation performance on the power plug 3 or the fixing component, improving the user experience. In addition, the connecting post 5 with the same structure also simplifies the structure of the first connector and the second connector, making them better fit the mounting slot 21, reducing production costs and improving production efficiency.

[0023] In this embodiment, the two locking components 2 have the same structure, the mounting groove 21 is a hemispherical groove structure, and the two limiting structures are set as two spherical panels 22 with the same structure. The opposite side of the two spherical panels 22 has an arc surface. The arc surface and the groove surface of the mounting groove 21 are fitted with the spherical surface of the sphere 6 with a gap, so that the display screen 1 is fixed by the friction force of the groove surface of the mounting groove 21 on the surface of the sphere 6, and the display screen 1 has more rotation angles, reducing the force required to rotate the display screen 1. Because the power plug 3 and the connecting post 5 of the fixing component have the same structure, and the two locking components 2 have the same structure, the structure of the tire pressure monitoring device is simplified, the production cost of the tire pressure monitoring device is reduced, and the production efficiency is improved.

[0024] In this embodiment, the top of the connecting seat 11 is provided with a protruding buckle 111 and the connecting structure is a concave buckle 23. The connecting seat 11 is connected to the concave buckles 23 of the two locking parts 2 by the protruding buckle 111, so that the two locking parts 2 can be more easily fixed to the rear surface of the housing of the display screen 1, thereby improving the efficiency of tire pressure monitoring equipment installation and disassembly.

[0025] In this embodiment, when the fixing component is set as a flat base 4, a ball 6 is provided on the top of the flat base 4. When the user chooses to place the tire pressure monitoring device on the flat surface, the flat base 4 can stably place the tire pressure monitoring device on the flat surface and can rotate the screen at a large angle, so that the user can adjust the angle of the display screen 1 and the position of the tire pressure monitoring device according to their habits, thereby improving the driving experience.

[0026] The advantages of this utility model are: 1. The display of this utility model is connected to the ball of the connecting post provided by the power plug or the mounting groove formed by two locking parts, so that the display screen can rotate at a large angle, allowing users to adjust the angle of the display screen according to their habits, thus improving the driving experience. 2. The two locking parts are detachably connected, allowing the ball of the connecting post on the power plug or the flat base to be removed from the mounting slot. Users can choose the fixing method of the tire pressure monitoring device according to the specific road conditions or habits, meeting the different needs of customers in different usage scenarios. 3. The two locking components have the same structure, which simplifies the mechanical structure and makes the production cost of the tire pressure monitoring equipment lower and the production efficiency higher.

[0027] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
