Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a clamping fixture for mounting elastic wave sensors. Background Technology

[0002] In today's automotive design landscape, where intelligence and user-friendliness are increasingly emphasized, enhancing the user experience through innovative interactive methods has become a key focus for automakers. Traditional hood opening methods require users to first enter the cabin, pull an internal unlock handle, and then manually unlock the hood at the front of the vehicle—a relatively cumbersome process. To improve convenience and technological sophistication, a contactless tap-to-open system has emerged. This system integrates a spring wave sensor within the front bumper, allowing users to trigger the hood to automatically pop open simply by tapping a specific area of ​​the trim panel.

[0003] However, the implementation of this function relies heavily on a seamless and tight bond between the sensor and the front bumper trim panel. The current manual assembly method has inherent defects such as uneven pressure application and inconsistent pressure holding time, resulting in unstable bonding quality. This can easily lead to sensor warping, detachment, or poor signal sensing, seriously affecting functional reliability and user experience. Utility Model Content

[0017] (III) Beneficial Effects

[0018] The beneficial effects of this utility model are:

[0019] This utility model discloses a clamping fixture for installing an elastic wave sensor, comprising a main mounting shell, a timer, a pressing assembly, and a pressing head assembly. The pressing head assembly is disposed at the front end of the main mounting shell and is used to abut against the elastic wave sensor on the outer side of the vehicle's front bumper trim panel to press the elastic wave sensor firmly. The pressing assembly includes a guide rod and a pressure unit. The guide rod is disposed within the main mounting shell and its front end is connected to the pressing head assembly.

[0034] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1 and Figure 2 As shown, this embodiment of the invention provides a clamping fixture for mounting an elastic wave sensor. The clamping fixture includes a main mounting shell 1, a timer 2, a pressing assembly 3, a pressing head assembly 4, a power supply 6, and a power supply mounting shell 7. The pressing head assembly 4 is disposed at the front end of the main mounting shell 1 and is used to abut against the elastic wave sensor on the outer side of the vehicle's front bumper trim panel to clamp the elastic wave sensor. The power supply mounting shell 7 is disposed on the outer side of the main mounting shell 1, and the two are integrally formed. The power supply 6 is housed within the power supply mounting shell 7 and is electrically connected to the timer 2 to supply power to the timer 2.

[0036] like Figure 3 As shown, the pressing assembly 3 includes a guide rod 31 and a pressure unit 32. The guide rod 31 is disposed within the main body mounting shell 1 and its front end is connected to the pressing head assembly 4. The pressure unit 32 is slidably sleeved on the guide rod 31 and is used to provide axial pressure to the guide rod 31. Because the guide rod 31 is disposed within the main body mounting shell 1 and its front end is connected to the pressing head assembly 4, and the pressure unit 32 is slidably sleeved on the guide rod 31, it provides accurate axial guidance for the pressing action, ensuring that the pressure always acts perpendicularly on the sensor surface.

[0037] The main mounting housing 1 has a limiting structure 5 inside. When the pressure unit 32 is subjected to external force and slides to contact the limiting structure 5, the pressure applied by the pressure head assembly 4 to the elastic wave sensor reaches a preset value. The timer 2 is set on the main mounting housing 1 and configured to be triggered and start timing when the pressure unit 32 contacts the limiting structure 5. By adjusting the position of the limiting structure 5 inside the main mounting housing 1, the preset pressure is adjusted. At the same time, by setting the limiting structure 5 and cooperating with the pressure unit 32, the synchronization of reaching the preset pressure and starting the pressure holding timer is achieved. This ensures that the pressure holding time for each bonding operation is calculated under exactly the same initial pressure conditions, completely eliminating deviations in time control due to human factors and ensuring the consistency and reliability of the process for each product. This clamping fixture integrates guiding, pressure setting, and timing functions into one unit. It is easy to operate, reduces reliance on the skills of operators, and significantly improves assembly efficiency.

[0038] like Figure 2 and Figure 3 As shown, the limiting structure 5 includes a tablet pressing trigger unit 51, which is communicatively connected to the timer 2. The tablet pressing trigger unit 51 is mounted on the main body mounting shell 1, and its trigger end is located inside the main body mounting shell 1. When the pressure unit 32 slides to abut against the trigger end of the tablet pressing trigger unit 51, the timer 2 is triggered and starts timing. By directly linking the sliding action of the tablet pressing trigger unit 51 with the pressure unit 32, the synchronization of the pressure reaching the preset value and the start of the timer 2 is achieved, avoiding the problem of false timing when the pressure has not reached the preset value. This further improves the accuracy of timing and the reliability of pressure control, ensuring that the pressing time of the elastic wave sensor under the preset pressure is recorded and guaranteeing the consistency of the installation process.

[0039] It is understood that the function of the tablet pressing trigger unit 51 can be achieved through various existing electronic triggering structures. For full illustration, this document provides a specific embodiment: the tablet pressing trigger unit 51 includes two trigger springs and a conductive ring. The two trigger springs are spaced apart on both sides of the side wall of the main body mounting shell 1 and are both connected to the timer 2 via wires. The conductive ring is located inside the main body mounting shell 1. When the pressure unit 32 slides to contact the trigger ends of the two trigger springs, the trigger ends simultaneously undergo mechanical deformation and contact the conductive ring, thereby closing the trigger signal circuit and outputting a start signal to the timer 2.

[0040] like Figure 3As shown, the limiting structure 5 also includes a limiting block 52, which is sleeved on the guide rod 31. The limiting block 52 is located on the side of the pressing trigger unit 51 facing away from the pressure unit 32, to limit the pressure unit 32. The limiting block 52 limits the sliding stroke of the pressure unit 32, preventing the pressure unit 32 from sliding excessively and avoiding the pressure of the pressure head assembly 4 on the sensor exceeding the preset value due to excessive sliding of the pressure unit 32, thereby effectively protecting the elastic wave sensor from damage by excessive pressure. In this embodiment, to balance the limiting function with the installation requirements of the conductive ring in the pressing trigger unit 51, the conductive ring is installed on the end face of the limiting block 52. Alternatively, the limiting block itself can form a conductive ring with a certain rigidity, thus simultaneously fulfilling the limiting and conductive functions.

[0041] The pressure unit 32 includes a pressure sleeve 321, an elastic element 322, and an arc-shaped handle 323. The pressure sleeve 321 is slidably sleeved on the guide rod 31. The elastic element 322 is disposed in the internal cavity of the pressure sleeve 321, with one axial end of the elastic element 322 abutting against the guide rod 31 and the other axial end abutting against the inner end wall of the pressure sleeve 321. The arc-shaped handle 323 is detachably disposed at the end of the pressure sleeve 321 away from the pressure head assembly 4. In this embodiment, the elastic element 322 is a spring. When the external force is removed, the elastic element 322 can push the pressure sleeve 321 to slide in the opposite direction along the guide rod 31 by its own elastic restoring force, so that it returns to its initial position, facilitating the rapid execution of the next pressing operation and improving the operating efficiency of the tooling. At the same time, the elastic element 322 can play a certain buffering role in the pressure transmission process. The curved handle 323 is ergonomically designed, making it easy for operators to grip and apply force, reducing operator fatigue. The detachable design allows the handle to be replaced individually when worn, without having to replace the entire pressure unit 32, thus reducing maintenance costs.

[0042] like Figure 3 As shown, the pressure sleeve 321 includes a sleeve body 3211 and a plug 3212. The sleeve body 3211 has a stepped through hole. The plug 3212 is threadedly connected to one end of the sleeve body 3211. The elastic element 322 is housed within the cavity formed by the stepped through hole and the plug 3212. One axial end of the elastic element 322 abuts against the guide rod 31, and the other axial end abuts against the plug 3212. The combination of the stepped through hole and the plug 3212 facilitates the installation, replacement, and maintenance of the elastic element 322 and the guide rod 31. The threaded plug 3212 allows for fine-tuning of its position within the sleeve body 3211, thereby adjusting the initial preload of the elastic element 322. This adapts to the preset pressure requirements of different sensors, enhancing the versatility of the tooling and the flexibility of pressure adjustment.

[0043] like Figures 3-5As shown, the pressure head assembly 4 includes a mounting base 41 and a pressing head 42. The mounting base 41 and the pressing head 42 are detachably connected. The mounting base 41 has a boss structure, and a portion of the mounting base 41 extends into the main mounting shell 1 and is detachably connected to it. The outer edge boss of the mounting base 41 abuts against the end face of the main mounting shell 1. The boss structure of the mounting base 41 and the abutting fit between its outer edge boss and the end face of the main mounting shell 1 facilitate rapid installation and positioning, improving the assembly efficiency and positioning accuracy of the overall tooling.

[0044] Among them, the pressing head 42 is a rubber head. The rubber material has good elasticity and flexibility, which can prevent hard materials from scratching or damaging the sensor surface when in contact with the elastic wave sensor. At the same time, the anti-slip property of the rubber can increase the friction with the sensor, ensuring that the sensor is not easily displaced during the pressing process, thus improving the pressing stability and the protection effect on the sensor.
