[0031] With the continuous improvement of the level of automobile intelligence, digital keys, as a kind of intelligent automobile keys, are convenient, fast, safe and reliable, and have been widely used. The tire pressure detection system is a key vehicle safety technology that can monitor the tire pressure of the vehicle, detect abnormal tire pressure in time, and improve driving safety. However, in the current relevant technical means, digital keys and tire pressure detection systems often exist as two independent devices, which cannot achieve functional interoperability and information sharing. At the same time, the two independent Bluetooth tire pressure detection devices and digital key technology devices have problems such as large space occupation and high cost.

[0032] To solve the technical problems described above, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] To solve the above technical problems, please refer to Figure 1 and Figure 2 The fusion device disclosed in this application includes an anchor component 1 and a main control component, and the anchor component 1 is connected to the main control component in communication. In the technical solution of this application, the original tire pressure detection module and the digital key module are fused, and the anchor component 1 formed after the fusion is set in the tire of the vehicle body. The anchor component 1 is provided with four groups and is placed in the four tires of the vehicle respectively (respectively located at the front left, rear left, front right and rear right of the vehicle), and the fused main control component is placed in the vehicle body (generally above the co-pilot glove box or glasses box).

[0034] See also Figure 2The anchor point assembly 1 includes a packaging shell 11, a control circuit board 12, a tire pressure detection module and a digital key module arranged in the packaging shell 11. The tire pressure detection module and the digital key module are arranged on the control circuit board 12 and are electrically connected to the control circuit board 12. The tire pressure detection module is used to detect the tire pressure data of the vehicle tire to adjust the working mode of the digital key module. The tire pressure detection data of the target vehicle is detected by the tire pressure detection module, and the working mode of the digital key is adjusted according to the tire pressure detection data, so as to achieve functional intercommunication and information sharing; the digital key module and the tire pressure detection module are integrated into the anchor point assembly. Compared with the prior art as two independent devices, the present application can reduce the equipment volume and the number of settings as much as possible, thereby reducing the occupied space volume and cost.

[0035] See also Figure 1 The packaging shell 11 is generally in the shape of a rectangular parallelepiped. The packaging shell 11 has a containing chamber. The packaging shell 11 includes an upper cover 111 and a base 112. The upper cover 111 and the lower cover 112 enclose the containing chamber. The control circuit board 12 is fixedly mounted on the base 112. A flange 1121 is provided at the end of the base 112 facing the upper cover 111. A plurality of limit blocks 1111 are provided at the end surface of the upper cover 111 facing the base 112. The limit blocks 1111 are arranged in contact with one side of the flange 1121. In this embodiment, four limit blocks 1111 are provided, which are respectively located at the four corners of the end surface of the upper cover 111 facing the base 112. The limit blocks 1111 are located on the side of the flange 1121 away from the center of the base 112. The limit blocks 1111 and the flange 1121 cooperate to position the upper cover 111 and the base 112, thereby limiting the sliding between the upper cover 111 and the base 112. The upper cover 111 and the base 112 are fixed by laser welding, which on the one hand enhances the connection stability between the upper cover 111 and the base 112, and on the other hand prevents water vapor from entering the accommodating chamber through the gap between the upper cover 111 and the base 112, thereby preventing the operation of the control circuit board 12 from being affected, thereby achieving a waterproof effect.

[0036] In one of the specific embodiments, the tire pressure detection module includes a vehicle speed sensor and an engine status sensor, and may also include a pressure sensor, a humidity sensor or an acceleration sensor, etc. Specifically, the anchor component can detect the vehicle speed or engine status of the vehicle through a vehicle sensor (such as a vehicle speed sensor or an engine status sensor, etc.), thereby obtaining the engine operating status data detected by the engine status sensor, and the vehicle speed data detected by the vehicle speed sensor. Among them, the engine operating status data can characterize whether the target vehicle is in a stopped state or a running state (or a driving state), and the vehicle speed data can characterize the current driving speed of the target vehicle (for example, 0-100km / h). The engine operating status data includes a stopped state and a running state. The stopped state is used to characterize that the target vehicle is in a stopped state, and the running state is used to characterize that the target vehicle is in a driving state. The vehicle speed data is used to describe the driving speed of the target vehicle. According to the above-mentioned engine operating status data and vehicle speed data 4, the tire pressure of the vehicle tire is determined, and then the working mode of the digital key is adjusted, thereby realizing the intercommunication of functions and the sharing of information.

[0037] In another feasible technical solution, the tire pressure, tire humidity or tire acceleration of the target vehicle may be detected respectively by a pressure sensor, a humidity sensor or an acceleration sensor, so as to determine the tire pressure of the vehicle tire.

[0038] See also Figure 3 and Figure 4 , an opening 113 is provided at one end of the encapsulation shell 11, and a connector 13 for communication is provided at the opening, one end of the connector 13 is electrically connected to the control circuit board 12, and the other end of the connector 13 is used to be electrically connected to the main control component. The connector 13 includes a plurality of wiring terminals 131, and the plurality of wiring terminals 131 are arranged side by side and at intervals, and are used to provide electrical connection points, and the signal line is reliably connected to other components on the control circuit board 12. In this embodiment, six wiring terminals 131 are provided, and the six wiring terminals 131 are arranged in two rows, and are respectively in contact with the corresponding connection components of the vehicle body to achieve corresponding functions. Further, a connecting portion 114 is provided on one end face of the encapsulation shell 11, and the connecting portion 114 is arranged in a hollow shape, and the connecting portion 114 is located outside the edge of the opening 113 and covers the wiring terminal 131, and the connecting portion 114 is used to be plugged into the vehicle body to interconnect the wiring terminal 131 with the main control component circuit.

[0039] See also Figure 4 and Figure 5In order to enhance the installation stability between the connector 13 and the vehicle body and reduce the loosening or falling off of the connector 13, the inner wall of the connecting portion of the packaging shell 11 is provided with a positioning block 115 for engaging with the vehicle body. The length direction of the positioning block 115 is consistent with the plugging direction of the terminal 131. The number and shape of the positioning block 115 can be set according to actual needs. In this embodiment, the positioning block 115 and the connecting portion 114 are integrally formed. When the connecting portion 114 is plugged into the vehicle body, the positioning block 115 engages with the corresponding structure of the vehicle body to enhance the plugging stability between the connecting portion 114 and the vehicle body.

[0040] The packaging shell 11 is vertically plugged into the vehicle body. Figure 3 and Figure 5 The outer peripheral wall of the connecting portion 114 is provided with a first clamping block 116 for clamping with the vehicle body. Two first clamping blocks 116 are provided and are symmetrically arranged along the central axis of the connecting portion 114. The first clamping block 116 is provided with a guiding slope. The distance between the guiding slope and the connecting portion 114 gradually increases along the insertion direction of the connecting portion 114. The guiding slope makes it easier for the first clamping block 116 to enter the vehicle body along with the connecting portion 114. The provision of the first clamping block 116 reduces the possibility of the connecting portion 114 falling off after being inserted into the vehicle body, and at the same time limits the displacement of the anchor assembly 1 along the insertion direction under the action of external force, further enhancing the connection stability of the connecting member 114.

[0041] For further information, see Figure 3 and Figure 5 The outer wall of the packaging shell 11 is provided with a plurality of second clamping blocks 117 for clamping with the vehicle body. The plurality of second clamping blocks 117 are respectively arranged on two opposite side walls of the packaging shell 11. In the present embodiment, four second clamping blocks 117 are provided. Two second clamping blocks 117 form a group and are located on the left and right side walls of the base 112. The second clamping blocks 117 are arranged at intervals along the length direction of the packaging shell 11 and are clamped with the corresponding structure of the vehicle body to limit the displacement of the packaging shell 11 in a direction perpendicular to the length direction of the packaging shell 11, thereby reducing the shaking of the anchor assembly 1 during operation.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents.
