Therefore, they should not be construed as limitations on the embodiments of this application.
[0043] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.
[0044] Regarding the installation of existing tire pressure sensors on the wheel hub, please refer to Figure 1. The figure shows the structure of the side of the existing tire pressure sensor. When assembling and fixing the sensor body 1 and the mounting bracket 2, first align the sensor body 1 and the mounting bracket 2 and slide them relative to each other in a direction perpendicular to the paper to initially position them. Then, screw screws 3 into both sides of the top and tighten them to fix the sensor body 1 and the mounting bracket 2 relative to each other, thus completing the assembly of the two.
[0045] For the assembly operations described above, before initially positioning the sensor body 1 and the mounting bracket 2 by sliding them relative to each other, it is necessary to ensure that the sliding mating structures on the sensor body 1 and the mounting bracket 2 are aligned. Furthermore, before screwing in the screws 3, it is also necessary to ensure that the holes on the mounting bracket 2 and the sensor body 1 are aligned. These alignment requirements make the operation quite difficult and cumbersome. In addition, during assembly and disassembly, a screwdriver is required to screw in or out the screws 3. This makes it impossible for users without a screwdriver to complete the assembly and disassembly themselves, and the screws are easily lost or come loose during the process, affecting the user experience.
[0046] To address the aforementioned issues, this application utilizes the characteristics of mechanical dead points and employs a special structural design for the bracket, enabling it to self-lock onto the mounting device after being subjected to force and deforming past the dead point of the mounting equipment (e.g., the sensor body), thereby achieving assembly and fixation between the bracket and the mounting device.
[0047] Based on this, according to one aspect of the embodiments of this application, a quick-release bracket assembly is provided. This quick-release bracket assembly can not only be used for fixing or supporting electronic devices such as tire pressure sensors, smart wearable devices, and mobile terminals, but also for the mutual assembly between mechanical parts.
[0048] Please refer to Figures 2 and 3 first. Figure 2 shows the three-dimensional structure of the quick-release bracket assembly after it is connected to the installation device. It should be noted that the figures are shown with the installation device being the sensor body of the tire pressure sensor as an example. This does not constitute a limitation on the specific implementation of the installation device. Figure 3 shows the side structure of the quick-release bracket assembly.
[0049] As shown in Figures 2 and 3, the quick-release bracket assembly 100 includes a first bracket 110 and a second bracket 120. The first bracket 110 and the second bracket 120 have the same structure, each including an abutment plate 131 and a snap-fit plate 132 that form an acute angle α with each other. The free end of the snap-fit plate 132 is provided with a hook 1321. The first bracket 110 and the second bracket 120 are mirror-symmetrically arranged with respect to the mirror surface shown by the dotted line in Figure 3, and the free ends of the abutment plate 131 on the first bracket 110 and the free ends of the abutment plate 131 on the second bracket 120 are arranged facing each other.
[0050] Based on the above structural design, regarding the assembly between the quick-release bracket assembly 100 and the installation device, please refer to the perspective view in Figure 4 and the cross-sectional view in Figure 5. Taking the sensor body 200 of the tire pressure sensor as an example, the installation device can be a boss or connecting shaft or other structure that allows the hook 1321 to hook on both sides of the top of the sensor body 200. Alternatively, slots can be pre-cut on the opposite sides of the sensor body 200 for the hook 1321 to extend into and hook on. First, hooks 1321 on the first bracket 110 and the second bracket 120 are hooked onto the sensor body 200 from both sides. After hooking, since the abutment plate 131 and the snap plate 132 form an acute angle, when the first bracket 110 and the second bracket 120 are pressed against the sensor body 200, the abutment plate 131 will abut against the edges on both sides of the bottom of the sensor body 200 to form dead points A and B as shown in Figure 5. At this time, slight pressure will not be able to make the first bracket 110 and the second bracket 120 fasten onto the sensor body 200.
[0051] Therefore, based on the state shown in Figure 5, greater pressure needs to be applied to the first bracket 110 and the second bracket 120 to cause the abutment plate 131 to press against the edges on both sides of the bottom of the sensor body 200 and deform. This causes the abutment plates 131 on the first bracket 110 and the second bracket 120 to cross the dead points A and B respectively and adhere to the bottom of the sensor body 200, forming the state shown in Figure 6. In this state, since the hook 1321 is engaged with the top of the sensor body 200, the first bracket 110 and the second bracket 120 can only be engaged by hooking. The mating point allows the axis to rotate relative to the sensor body 200. However, the abutment plate 131, which is set at an acute angle to the snap plate 132, cannot rotate due to the restriction of the bottom of the sensor body 200 when it is in contact with the bottom of the sensor body 200. In summary, under the mutual cooperation of the snap hook 1321 hooking with the top of the sensor body 200 and the abutment plate 131 in contact with the bottom of the sensor body 200, the first bracket 110 and the second bracket 120 are respectively self-locked and fixed on both sides of the sensor body 200, thereby achieving the assembly and fixation with the sensor body 200.
[0052] Conversely, during disassembly, the first bracket 110 and the second bracket 120 can be rotated by placing fingers on the free end of the abutment plate 131 and applying outward pulling force, and the abutment plate 131 can be reversed to cross the aforementioned dead points A and B. Then, the sensor body 200 can be easily separated from the first bracket 110 and the second bracket 120, thus achieving easy disassembly of the sensor body 200.
[0053] Some installation devices need to be mounted on a carrier. For example, the sensor body 200 needs to be mounted on the wheel hub to detect tire pressure. As shown in Figure 7, the quick-release bracket assembly 100 may also include a strap 140. A connection hole 150 is provided at the adjacent junction of the abutment plate 131 and the snap-fit plate 132. The strap 140 passes through the connection hole 150 on the first bracket 110 and exits through the connection hole 150 on the second bracket 120, and is then strapped to the wheel hub 400. With the first bracket 110 and the second bracket 120 respectively fixedly connected to the sensor body 200, the abutment plate 131 can be pressed tightly onto the wheel hub 400 by the strap 140 to fix the sensor body 200 to the wheel hub 400.
[0054] In addition to fixing the sensor body 200 to the wheel hub 400, smart wearable devices generally need to be installed on specific parts of the human body to achieve corresponding functions. By binding the strap 140 to the corresponding parts of the human body, the smart wearable device can also be installed and fixed on the human body.
[0055] The quick-release bracket assembly 100 can also serve as a connecting bracket for electronic devices. For electronic devices that require fixed installation for operation and frequent disassembly for charging or battery replacement (such as monitors and video doorbells), a fixing structure (such as screws or rivets) is typically installed on a wall, ceiling, or other substrate, and a detachable connecting bracket is installed on the main body of the electronic device. During installation, the main body of the electronic device and the connecting bracket are first assembled and fixed together, and then the connecting bracket is fixedly connected to the fixing structure on the substrate, thereby achieving the installation and fixation of the main body of the electronic device on the wall, ceiling, or other substrate. When the quick-release bracket assembly 100 provided in this application embodiment is used as such a connecting bracket, the user can easily assemble and disassemble the connecting bracket and the main body of the electronic device without tools.
[0056] In addition, for mobile terminals, the quick-release bracket assembly 100 can also serve as a support frame to tilt or vertically support the mobile terminal. In this case, there is no need for the strap 140. Instead, a protruding support member can be provided on the side of the abutment plate 131 of the first bracket 110 or the second bracket 120 away from the mobile terminal. For example, it can be a support block, support rod, support plate, etc. After the first bracket 110 and the second bracket 120 are respectively fastened and self-locked to both sides of the mobile terminal, the first bracket 110, the second bracket 120 and the mobile terminal as a whole are placed on the table. The support member abuts against the table at the back, so that the mobile terminal is placed on the table in a tilted or vertical state. Of course, the table can also be any other flat surface used to place the mobile terminal.
[0057] In addition to the above-mentioned application scenarios, the quick-release bracket assembly 100 can also be used for the assembly between mechanical parts. For example, the first bracket 110 and the second bracket 120 can be used as connecting parts to assemble two mechanical parts together.
[0058] In summary, the quick-release bracket assembly 100 provided in this application embodiment, by setting the abutment plate 131 and the snap-fit plate 132 on the first bracket 110 and the second bracket 120 at an acute angle to each other, and setting the snap-fit hook 1321 at the free end of the snap-fit plate 132, the first bracket 110 and the second bracket 120 are first hooked onto the installation equipment from both sides, and then the first bracket 110 and the second bracket 120 are pressed so that the abutment plate 131 passes over the dead points at the bottom edges of the installation equipment. Then the first bracket 110 and the second bracket 120 can be easily fixed and connected to the installation equipment and self-locked. Disassembly can be performed by reversing the operation. The entire disassembly and assembly process does not require the use of tools, is easy and labor-saving, and has high efficiency.
[0059] According to another aspect of the embodiments of this application, a tire pressure sensor is provided. Please refer to Figure 7 again for details. The tire pressure sensor 300 includes a sensor body 200 and a quick-release bracket assembly 100 as described in any of the above embodiments. The first bracket 110 and the second bracket 120 are used to fix the sensor body 200 to the sensor body, and then the abutment plate 131 is pressed onto the wheel hub 400 by the strap 140, so that the sensor body 200 is installed and fixed on the wheel hub 400, thereby realizing the monitoring of the tire pressure of the automobile tire.
[0060] To enable the quick-release bracket assembly 100 to better fix the sensor body 200 to the wheel hub 400, as shown in the side structure of the tire pressure sensor 300 fixed to the wheel hub 400 in Figure 8, the bottom of the sensor body 200 is concave arc-shaped. That is, from the perspective shown in Figure 8, the bottom of the sensor body 200 is an arc surface with the middle area concave upward. Correspondingly, the abutment plate 131 is an arc shape that fits against the bottom of the sensor body 200. With this setting, the abutment plate 131 on the first bracket 110 and the second bracket 120 forms an arc shape that matches the outer periphery of the wheel hub 400 on the side away from the sensor body 200. Thus, after the abutment plate 131 is attached to the wheel hub 400 on the side away from the sensor body 200 by the strap 140, the abutment plate 131 and the wheel hub 400 fit tightly together, and the two have a larger contact area, thereby improving the stability and reliability of the tire pressure sensor 300 installed and fixed on the wheel hub 400.
[0061] Regarding the connection between the hook 1321 and the sensor body 200, as shown in the exploded structure of the tire pressure sensor 300 in Figure 9, protrusions 210 can be provided on both sides of the top of the sensor body 200, and the hook 1321 is hooked onto the protrusions 210.
[0062] By providing protrusions 210 on both sides of the top of the sensor body 200, when connecting the first bracket 110 and the second bracket 120 to the sensor body 200, the hook 1321 can be easily aligned and engaged with the protrusions 210, thereby facilitating the assembly of the first bracket 110 and the second bracket 120 with the sensor body 200.
[0063] Furthermore, to prevent breakage of the hook 1321 and the boss 210 due to excessive compression during the assembly of the quick-release bracket assembly 100 and the sensor body 200, as shown in Figure 10a when the hook 1321 is initially engaged with the boss 210 and in Figure 10b when the assembly is completed, the hook 1321 itself can form an acute angle β, and the two opposite sides of the boss 210 can form an acute angle θ, where β>θ. When the hook 1321 rotates counterclockwise from the initial engagement state with the boss 210 as shown in Figure 10a for assembly, since β>θ, there is a certain gap C between the inside of the hook 1321 and the left side of the boss 210. This gap C forms space for the hook 1321 to rotate, so that during the rotation of the hook 1321 to the state shown in Figure 10b, there will be no excessive compression or deformation between the hook 1321 and the boss 210, ensuring that the hook 1321 and the boss 210 are not prone to compression breakage during assembly. As shown in Figure 10b, after assembly, similarly, there is a certain gap D between the inside of the hook 1321 and the right side of the boss 210. This gap D provides space for the hook 1321 to rotate clockwise when disassembling the quick-release bracket assembly 100, ensuring that there will be no excessive compression or deformation between the hook 1321 and the boss 210 during disassembly.
[0064] The first bracket 110 and the second bracket 120, through the cooperation of the hook 1321 and the abutment plate 131 with the sensor body 200, can form a stable limiting and fixing in the directions shown by the double arrows X and Z in Figure 9. However, in the direction shown by the double arrow Y in Figure 9, if there are no other components for limiting, the first bracket 110 and the second bracket 120 can only restrict each other with friction with the sensor body 200, and its stability will inevitably be greatly reduced.
[0065] In response, this application further incorporates a limiting design for the first bracket 110 and the second bracket 120 in the direction indicated by the double arrow Y. Specifically, as shown in Figure 9, limiting portions 220 can be provided on both sides of the boss 210. The limiting portions 220 are used to restrict the sliding of the hook 1321 relative to the boss 210 in the direction indicated by the double arrow Y by abutting against both sides of the hook 1321. Based on the limiting of the hook 1321 and the abutting plate 131 in the directions indicated by the double arrow X and double arrow Z in cooperation with the sensor body 200, the quick-release bracket assembly 100 and the sensor body 200 are fixed in the three-axis direction, which fully ensures the stability of the connection between the sensor body 200 and the quick-release bracket assembly 100.
[0066] When installing the tire pressure sensor 300 onto the wheel hub 400, the first bracket 110 and the second bracket 120 are typically connected to the sensor body 200 first, then the strap 140 is passed through the connection hole 150, and finally the strap 140 is tied to the wheel hub 400 to complete the installation. Considering that after the free end of the strap 140 is inserted into the interior through the connection hole 150 on the first bracket 110, since the free end of the strap 140 located inside cannot be controlled, it is easy for the free end to press against the internal structure and fail to smoothly exit through the connection hole 150 on the second bracket 120.
[0067] To facilitate the easy and smooth passage of the strap 140, this application also includes a guiding structure for the strap 140. Referring to Figure 11, the bottom of the sensor body 200 has at least two parallel protrusions 230, and the abutment plate 131 is attached to the bottom of the protrusions 230. The two ends of the protrusions 230 face the connecting holes 150 on the first bracket 110 and the second bracket 120, respectively, so that a channel 240 for the strap 140 to pass through is formed between the at least two protrusions 230.
[0068] Specifically, when there is only one strap 140, the protrusions 230 can be set as two as shown in Figure 11 and located on both sides respectively. For the method of using multiple straps 140 to work together for binding, the protrusions 230 can be multiple parallel to each other, and a channel 240 is formed between two adjacent protrusions 230 for a strap 140 to pass through.
[0069] By setting at least two parallel protrusions 230 at the bottom of the sensor body 200 and attaching the abutment plate 131 to the bottom of the protrusions 230, the strap 140 inserted through the connection hole 150 can easily and smoothly pass through the other connection hole 150 under the guidance of the two protrusions 230, thus realizing the convenient installation of the tire pressure sensor 300 on the wheel hub 400.
[0070] For the specific structure of the sensor body 200, please refer to Figure 12. The sensor body 200 includes a circuit element 250, a housing 260, and a baffle 270. The bottom of the housing 260 is provided with a mounting port 261. The circuit element 250 is installed inside the housing 260 through the mounting port 261. The baffle 270 is provided at the bottom of the housing 260 and covers at least part of the mounting port 261. The abutment plate 131 is attached to the bottom of the baffle 270. The strap 140 passes between the baffle 270 and the abutment plate 131.
[0071] Considering the harsh working environment of the tire pressure sensor 300, to improve the waterproof, dustproof, heat insulation, and vibration resistance performance of the circuit component 250, after the circuit component 250 is installed inside the housing 260, it is wrapped and fixed by applying adhesive through the mounting port 261 to ensure the reliability of the circuit component 250. Typically, after applying the adhesive, no additional baffle is needed at the mounting port 261 to ensure the stability of the circuit component 250. Furthermore, to improve the stability of the tire pressure sensor 300 mounted on the wheel hub 400, the strap 140 is usually made of a high-strength metal strip. Practical testing revealed that when the strap 140 is made of metal and no additional baffle is provided at the mounting port 261, after the tire pressure sensor 300 is installed on the wheel hub 400, as the wheel hub 400 rolls, the portion of the strap 140 located inside the abutment plate 131 will arch towards the inside of the housing 260 due to centrifugal force, as shown in the cross-sectional structure in Figure 13. This situation will cause friction and collision between the strap 140 and the adhesive layer inside the housing 260, and even the circuit components 250, which will affect the stability of the circuit components 250.
[0072] Based on this, by providing a baffle 270 at the bottom of the housing 260 that closes at least part of the mounting opening 261, and by passing the strap 140 between the baffle 270 and the abutment plate 131, the baffle 270 can limit the arching of the strap 140 when it tends to arch towards the housing 260 due to centrifugal force, so as to ensure that the strap 140 will not damage the adhesive layer and circuit components 250 inside the housing 260.
[0073] To facilitate the assembly of the sensor body 200, as shown in Figure 12, protrusions 262 can be provided on both sides of the housing 260, and buckles 271 are provided on both sides of the baffle 270. After the circuit components 250 are installed and fixed in the housing 260, the buckles 271 and protrusions 262 are engaged by pressing the baffle 270, so that the baffle 270 can be easily fixed and assembled on the housing 260 and at least part of the mounting opening 261 is closed, which helps to improve the assembly efficiency of the sensor body 200.
[0074] Based on the assembly of the baffle 270 with the snap-fit 271 on both sides of the housing 260 and the snap-fit protrusion 262 on both sides, considering that the snap-fit 271 protruding on the side will affect the installation of the first bracket 110 and the second bracket 120, as shown in Figure 12, the snap-fit plate 132 is provided with a clearance hole 1322. The clearance hole 1322 communicates with the connection hole 150. When the abutment plate 131 is attached to the bottom of the baffle 270, that is, after the first bracket 110 and the second bracket 120 are fixedly connected to the sensor body 200, the snap-fit 271 can be accommodated in the clearance hole 1322 as shown in Figure 14.
