[0049] For installation of existing tire pressure sensors on wheels, see Figure 1 The figure shows the side structure of an 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 surface for preliminary positioning. Then, screw in screws 3 on both sides of the top and tighten them to fix the sensor body 1 and the mounting bracket 2 relative to each other, completing the assembly of the two.

[0050] For the aforementioned assembly operation, before the sensor body 1 and mounting bracket 2 are initially positioned by sliding them relative to each other, it is necessary to ensure that the sliding fitting structures on the sensor body 1 and mounting bracket 2 are aligned with each other. Furthermore, before screwing in the screws 3, it is also necessary to ensure that the holes on the mounting bracket 2 and sensor body 1 are aligned with each other. These alignment requirements make the operation difficult and cumbersome. Furthermore, during disassembly, a screwdriver is required to screw in or out the screws 3, which makes it difficult for users without a screwdriver to complete the disassembly and assembly themselves. Furthermore, the screws can easily fall off and be lost during disassembly and assembly, affecting the user experience.

[0051] To address the above-mentioned problems, this application utilizes the characteristics of the mechanical dead point and designs the bracket in a special structure so that it can self-lock on the mounting device after being subjected to force and deforming to cross the dead point of the mounting device (such as the sensor body), thereby achieving assembly fixation with the mounting device.

[0052] Based on this, according to one aspect of an embodiment of the present application, a quick-release bracket assembly is provided, which can not only be used for fixing or supporting electronic devices such as tire pressure sensors, smart wearable devices, and mobile terminals, but can also be used for mutual assembly between mechanical parts.

[0053] First see Figure 2 and Figure 3 , Figure 2 The figure shows the three-dimensional structure after the quick-release bracket assembly is connected to the mounting device. It should be noted that the drawings are all illustrated by taking the mounting device as the sensor body of the tire pressure sensor as an example, which does not constitute a limitation on the specific implementation method of the mounting device. Figure 3 The side structure of the quick-release bracket assembly is shown in FIG.

[0054] like Figure 2 and Figure 3 As shown in FIG, 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, and both include a contact plate 131 and a clamping plate 132 that form an acute angle α with each other. The free end of the clamping plate 132 is provided with a hook 1321. Figure 3 The mirror surfaces indicated by the dotted lines are arranged in mirror symmetry, and the free end of the abutting plate 131 on the first bracket 110 and the free end of the abutting plate 131 on the second bracket 120 are arranged facing each other.

[0055] Based on the above structural design, for the assembly between the quick release bracket assembly 100 and the installation equipment, please refer to Figure 4 Stereoscopic perspective and Figure 5From a cross-sectional perspective, the figure takes the sensor body 200 in which the installation device is a tire pressure sensor as an example. Bosses or connecting shafts or other structures for the hook 1321 to hook can be pre-set on both sides of the top of the sensor body 200. Of course, slots for the hook 1321 to extend into and hook can also be pre-opened on the two opposite sides of the sensor body 200. First, hook the hooks 1321 on the first bracket 110 and the second bracket 120 to the sensor body 200 from both sides. After hooking, since the abutment plate 131 and the clamping 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 a shape as shown in FIG. Figure 5 At the dead points A and B shown in FIG, slight pressure will not be able to make the first bracket 110 and the second bracket 120 snap onto the sensor body 200.

[0056] Therefore, in Figure 5 Based on the state shown, it is necessary to apply a large pressure to the first bracket 110 and the second bracket 120 so that the edges of the abutting plate 131 and the two sides of the bottom of the sensor body 200 are squeezed and deformed, so that the abutting plates 131 on the first bracket 110 and the second bracket 120 respectively cross the dead points A and B and fit on the bottom of the sensor body 200, forming Figure 6 In the state shown, since the hook 1321 is hooked and engaged with the top of the sensor body 200, the first bracket 110 and the second bracket 120 can only rotate relative to the sensor body 200 with the hooking point as the axis, and the abutment plate 131, which is set at an acute angle to the clamping plate 132, will be restricted by the bottom of the sensor body 200 and cannot rotate when it is in contact with the bottom of the sensor body 200. In summary, under the mutual cooperation of the 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 realizing assembly and fixation with the sensor body 200.

[0057] On the contrary, during disassembly, you can hold the free end of the abutment plate 131 with your fingers and apply outward pulling force to rotate the first bracket 110 and the second bracket 120 and the abutment plate 131 crosses the above-mentioned dead points A and B in the opposite direction. Then, the sensor body 200 can be easily separated from the first bracket 110 and the second bracket 120, thereby achieving easy disassembly of the sensor body 200.

[0058] Some mounting devices need to be mounted on a carrier, for example, the sensor body 200 needs to be mounted on a wheel hub to detect tire pressure. Figure 7As shown in the figure, the quick-release bracket assembly 100 may further include a strap 140, and a connecting hole 150 is provided at the adjacent portion of the abutment plate 131 and the clamping plate 132. The strap 140 passes through the connecting hole 150 on the first bracket 110 and exits from the connecting hole 150 on the second bracket 120, and is then tied to the wheel hub 400. On the basis that the first bracket 110 and the second bracket 120 are respectively fixedly connected to the sensor body 200, the abutment plate 131 is pressed against the wheel hub 400 by the strap 140, so that the sensor body 200 can be fixed to the wheel hub 400.

[0059] 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 tying the strap 140 to the corresponding part of the human body, the smart wearable device can also be installed and fixed on the human body.

[0060] The quick-release bracket assembly 100 can also be used as a connecting bracket for electronic devices. For electronic devices that need to be fixed and installed to work, and also need to be frequently disassembled for charging or battery replacement (such as monitors, video doorbells, etc.), a fixed structure (such as screws, rivets, etc.) is generally provided on a carrier such as a wall or ceiling, and a detachable connecting bracket is provided on the electronic device body. During installation, the electronic device body and the connecting bracket are first assembled and fixed to each other, and then the connecting bracket is fixedly connected to the fixed structure on the carrier, so as to achieve the installation and fixation of the electronic device body on a carrier such as a wall or ceiling. When the quick-release bracket assembly 100 provided in an embodiment of the present application is used as such a connecting bracket, the user can easily complete the assembly and disassembly between the connecting bracket and the electronic device body without the need for tools.

[0061] In addition, if the installation device is a mobile terminal, the quick-release bracket assembly 100 can also serve as a support bracket for tilting or vertically supporting the mobile terminal. In this case, the strap 140 is not required. Instead, a raised support member can be provided on the abutment plate 131 of the first bracket 110 or the second bracket 120 on the side facing away from the mobile terminal. For example, it can be a support block, a support rod, a support plate, etc. On the basis of the first bracket 110 and the second bracket 120 being respectively buckled and self-locked on both sides of the mobile terminal, after the first bracket 110, the second bracket 120 and the mobile terminal are placed on the desktop as a whole, the support member is abutted against the desktop at the back to place the mobile terminal on the desktop in a tilted or vertical state. Of course, the desktop can also be other planes for placing mobile terminals.

[0062] In addition to the above application scenarios, the quick-release bracket assembly 100 can also be used for assembling mechanical parts. For example, the first bracket 110 and the second bracket 120 can be used as connecting components to assemble two mechanical parts together.

[0063] To sum up, in the quick-release bracket assembly 100 provided in the embodiment of the present application, the abutment plate 131 and the clamping plate 132 on the first bracket 110 and the second bracket 120 are set at an acute angle to each other, and a hook 1321 is set at the free end of the clamping plate 132, so that the hooks 1321 on the first bracket 110 and the second bracket 120 are first hooked onto the mounting device from both sides respectively, and then the first bracket 110 and the second bracket 120 are pressed so that the abutment plate 131 crosses the dead points at the edges on both sides of the bottom of the mounting device. Then, the first bracket 110 and the second bracket 120 can be easily fixedly connected to the mounting device and self-locked. When disassembling, the operation can be reversed. The entire disassembly and assembly process does not require the aid of tools, which is easy, labor-saving and efficient.

[0064] According to another aspect of the embodiment of the present application, a tire pressure sensor is provided. Figure 7 The tire pressure sensor 300 includes a sensor body 200 and a quick-release bracket assembly 100 in any of the above embodiments. After the first bracket 110 and the second bracket 120 are fixedly connected to the sensor body 200, the abutment plate 131 is pressed against the wheel hub 400 through 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.

[0065] In order to enable the quick release bracket assembly 100 to better fix the sensor body 200 on the wheel hub 400, as shown in FIG. Figure 8 The side structure of the tire pressure sensor 300 when fixed to the wheel hub 400 is shown in FIG. 1 , the bottom of the sensor body 200 is in an inwardly concave arc shape, that is, Figure 8 From the perspective shown, the bottom of the sensor body 200 is an arc surface with an upward concave middle area. Correspondingly, the abutment plate 131 is an arc that fits the bottom of the sensor body 200. After being set in this way, the abutment plate 131 on the first bracket 110 and the second bracket 120 forms an arc that is adapted to the outer periphery of the wheel hub 400 on the side facing away from the sensor body 200. Therefore, after the side of the abutment plate 131 facing away from the sensor body 200 is fitted on the wheel hub 400 through the strap 140, the abutment plate 131 is tightly fitted to the wheel hub 400, 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.

[0066] Regarding the connection between the hook 1321 and the sensor body 200, as shown in FIG. Figure 9 As shown in the exploded structure of the tire pressure sensor 300 , bosses 210 can be set on both sides of the top of the sensor body 200 , and the hooks 1321 are hooked on the bosses 210 .

[0067] By setting bosses 210 on both sides of the top of the sensor body 200, when the first bracket 110 and the second bracket 120 are connected to the sensor body 200, the hook 1321 can be easily aligned and hooked with the boss 210, which is conducive to the convenience of assembling the first bracket 110 and the second bracket 120 with the sensor body 200.

[0068] Furthermore, in order to prevent the hook 1321 and the boss 210 from being broken due to excessive extrusion when the quick-release bracket assembly 100 and the sensor body 200 are assembled, Figure 10a The state in which the middle hook 1321 is initially hooked with the boss 210 and Figure 10b As shown in the state where the hook 1321 is hooked with the boss 210 after 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, β>θ. Figure 10a When the hook 1321 is initially engaged with the boss 210 and rotated counterclockwise 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. The gap C forms a space for the hook 1321 to rotate, so that the hook 1321 rotates to Figure 10b During the state shown, there will be no excessive extrusion and deformation between the hook 1321 and the boss 210, ensuring that the hook 1321 and the boss 210 are not prone to extrusion and fracture when assembled. Figure 10b As shown, after assembly is completed, there is also a certain gap D between the inside of the hook 1321 and the right side of the boss 210. The gap D can provide clockwise rotation space for the hook 1321 when disassembling the quick-release bracket assembly 100, so as to ensure that excessive extrusion and deformation will not occur between the hook 1321 and the boss 210 during disassembly.

[0069] The first bracket 110 and the second bracket 120 cooperate with the sensor body 200 through the hook 1321 and the abutment plate 131. Figure 9 The directions indicated by the double arrows X and Z form a stable limit fixation, and Figure 9 In the direction indicated by the double arrow Y, if there is no other component to limit the position, the first bracket 110, the second bracket 120 and the sensor body 200 can only be restricted by friction, and their stability will inevitably be greatly reduced.

[0070] In this regard, the present application further provides a position limiting design for the first bracket 110 and the second bracket 120 in the direction indicated by the double arrow Y. Specifically, Figure 9As shown in the figure, limiting portions 220 can be provided on both sides of the boss 210, and the limiting portions 220 are used to limit the sliding of the hook 1321 relative to the boss 210 along the direction indicated by the double arrow Y by abutting against the two sides of the hook 1321. Based on the limitation of the hook 1321 and the abutment plate 131 in the directions indicated by the double arrow X and the double arrow Z with the sensor body 200, the quick-release bracket assembly 100 and the sensor body 200 are fixed in three-axis directions, which fully ensures the stability of the connection between the sensor body 200 and the quick-release bracket assembly 100.

[0071] When installing tire pressure sensor 300 on wheel hub 400, first, first bracket 110 and second bracket 120 are typically connected to sensor body 200. Then, strap 140 is passed through connection hole 150, and finally, strap 140 is tied to wheel hub 400 to complete installation. However, after the free end of strap 140 is passed through connection hole 150 on first bracket 110 and inserted into the wheel hub, it is difficult to control the free end of strap 140 while inside. This can easily cause the free end to hit the internal structure and prevent it from passing smoothly through connection hole 150 on second bracket 120.

[0072] In order to make the strap 140 pass through easily and smoothly, the present application also designs a structure for guiding the strap 140. For details, please refer to Figure 11 The bottom of the sensor body 200 is provided with at least two parallel protrusions 230, and the abutment plate 131 is attached to the bottom of the protrusions 230. The ends of the protrusions 230 face the connection holes 150 on the first bracket 110 and the second bracket 120, respectively, so that a channel 240 is formed between the at least two protrusions 230 for the strap 140 to pass through.

[0073] Specifically, when there is only one strap 140, the convex strip 230 can be as follows: Figure 11 As shown, there are two ribs 230 located on both sides. For the method of using multiple straps 140 to cooperate with each other for binding, the ribs 230 can be multiple and parallel to each other, and a channel 240 for a strap 140 to pass through is formed between two adjacent ribs 230.

[0074] By setting at least two parallel protrusions 230 at the bottom of the sensor body 200 and fitting the abutment plate 131 to the bottom of the protrusion 230, the strap 140 inserted into the connecting hole 150 can be easily and smoothly passed through the other connecting hole 150 under the guidance of the protrusions 230 on both sides, thereby realizing convenient installation of the tire pressure sensor 300 on the wheel hub 400.

[0075] For the specific structure of the sensor body 200, please refer to Figure 12The sensor body 200 includes a circuit element 250, a shell 260 and a baffle 270. A mounting opening 261 is provided at the bottom of the shell 260. The circuit element 250 is installed inside the shell 260 through the mounting opening 261. The baffle 270 is provided at the bottom of the shell 260 and covers at least part of the mounting opening 261. The abutment plate 131 is attached to the bottom of the baffle 270, and the strap 140 is passed between the baffle 270 and the abutment plate 131.

[0076] Considering the relatively harsh working environment of the tire pressure sensor 300, in order to improve the waterproof, dustproof, heat-insulating, and vibration-resistant properties of the circuit element 250, the circuit element 250 is generally installed inside the shell 260, and then glue is poured from the installation port 261 to wrap and fix the circuit element 250 to ensure the reliability of the circuit element 250. Usually, after glue pouring, the stability of the circuit element 250 can be ensured without setting an additional baffle at the installation port 261. In addition, in order to improve the stability of the tire pressure sensor 300 installed on the wheel hub 400, the strap 140 usually uses a metal strap with higher structural strength. Through practical tests, it was found that when the strap 140 uses a metal strap and no additional baffle is set at the installation port 261, after the tire pressure sensor 300 is installed on the wheel hub 400, when the wheel hub 400 rolls, the strap 140 will be arched toward the inside of the shell 260 due to the action of centrifugal force, forming a Figure 13 The state shown in the middle cross-sectional structure may cause friction and collision between the strap 140 and the adhesive layer in the housing 260 or even the circuit element 250 , thereby affecting the stability of the circuit element 250 .

[0077] Based on this, a baffle 270 is provided at the bottom of the shell 260 to close at least part of the installation opening 261, and the strap 140 is passed between the baffle 270 and the abutment plate 131, so that when the strap 140 has a tendency to arch toward the shell 260 due to the action of centrifugal force, the baffle 270 can limit the arching of the strap 140 to ensure that the strap 140 will not damage the glue layer inside the shell 260 and the circuit element 250.

[0078] In order to facilitate the assembly of the sensor body 200, as Figure 12 As shown, protrusions 262 can be set on both sides of the shell 260, and buckles 271 are correspondingly set on both sides of the baffle 270. After the circuit element 250 is installed and fixed in the shell 260, the baffle 270 is pressed to engage the buckle 271 with the protrusion 262. Then, the baffle 270 can be easily fixed and assembled on the shell 260 and at least part of the installation opening 261 can be closed, which is beneficial to improving the assembly efficiency of the sensor body 200.

[0079] On the basis of assembling the baffle 270 by snapping the buckles 271 on both sides with the protrusions 262 on both sides of the shell 260, considering that the protruding buckles 271 on the side will affect the installation of the first bracket 110 and the second bracket 120, Figure 12 As shown in FIG, a position-avoiding hole 1322 is provided on the snap-on plate 132, and the position-avoiding hole 1322 is communicated with the connecting hole 150. When the abutting 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 buckle 271 can be as shown in FIG. Figure 14 As shown, it is accommodated in the avoidance hole 1322.
