Description

Technical Field

[0001] This application relates to the technical field of virtual pedals for automobiles, and in particular to an integrated injection-molded virtual pedal assembly. Background Technology

[0002] Virtual pedals are a car function that enables contactless operation through sensing technology, mainly used to unlock the trunk or doors.

[0003] In related technologies, a virtual pedal assembly typically consists of an ECU assembly (electronic control unit) and sensing electrodes. The ECU assembly is formed by laser welding an ECU housing and a PCBA with a pin cover. The sensing electrode assembly is typically formed by a combination of round electrodes A and flat electrodes B, which can be AA, BB, AB, or BA, and then connected (usually crimped) to a connector terminal. The connector terminal needs to contain a waterproof plug and pins.

[0004] In the aforementioned technical solutions, regardless of the combination of AA, BB, AB, or BA, the sensing electrode assembly requires a waterproof plug or other structure to achieve a seal, which can easily lead to a complex structure for the virtual pedal assembly. Utility Model Content

[0005] To address the issues of complex structure in virtual pedal assemblies, this application provides an integrated injection-molded virtual pedal assembly.

[0006] This application provides an integrated injection-molded virtual pedal assembly, which adopts the following technical solution: An integrated injection-molded virtual pedal assembly includes a housing assembly, a PCBA assembly, and a cover plate. The housing assembly and the cover plate are sealed and fixedly connected. The PCBA assembly is installed in the space formed by the housing assembly and the cover plate. The housing assembly includes a cable assembly and an ECU housing. The cover plate is fixedly connected to the ECU housing. One end of the cable assembly is located inside the ECU housing and is connected to the PCBA assembly for signal transmission. The other end of the cable assembly extends out of the space formed by the housing assembly and the cover plate.

[0007] By adopting the above technical solution, components such as connector terminals and waterproof plugs are eliminated, which simplifies the overall structure and installation steps of the virtual pedal assembly, thereby reducing the cost of components and assembly.

[0008] The housing assembly also includes a pin assembly, one end of which is fixedly connected to the ECU housing. The pin assembly includes two sets of signal-connected pins, one set of which is plugged into the PCBA assembly and the other set of which is plugged into the cable assembly.

[0009] By adopting the above technical solution, the signal connection between the cable group and the PCBA assembly is realized through the PIN pin assembly, which is convenient for the staff to assemble and has a simple structure; the installation can be completed by the staff by performing only two plug-in actions.

[0010] Preferably, the PIN assembly further includes a plastic-coated body, which is fixedly connected to the ECU housing. One set of PIN pins is disposed on the side of the plastic-coated body away from the ECU housing, and another set of PIN pins is disposed on the side wall of the plastic-coated body, forming a 90-degree angle with the first set of plastic-coated bodies.

[0011] By adopting the above technical solution, the position of the two sets of pins can be restricted by the plastic coating, ensuring normal signal connection between the cable group and the PCBA assembly. At the same time, the structure is simple and can save costs.

[0012] Preferably, the cover plate and the ECU housing are fixedly connected by laser welding.

[0013] By adopting the above technical solution, laser welding is used to form a fixed connection between the cover plate and the ECU housing, and to create a hollow space for placing PCBA assemblies and other components.

[0014] Preferably, the cable assembly includes two electrodes, which are either round or flat electrodes.

[0015] By adopting the above technical solution, staff can use different electrode combinations according to different usage environments, such as two round electrodes, two flat electrodes, or a combination of one round electrode and one flat electrode.

[0016] Preferably, the circular electrode includes a coaxial cable and an end injection block. One end of the coaxial cable is connected to the signal of the PCBA assembly, and the other end is fixedly connected to the end injection block. The coaxial cable and the end injection block are covered with heat shrink tubing.

[0017] By adopting the above technical solutions, the coaxial cable is directly connected to the PCBA assembly, reducing signal loss and interference and ensuring stable transmission; the end injection molding block fixation prevents displacement that could lead to poor contact. The outer heat shrink tubing forms an overall protection, enhancing structural strength, isolating dust and water, improving durability and environmental adaptability, while simplifying assembly and reducing maintenance costs.

[0018] Preferably, the flat electrode B includes a thin-walled wire, an adhesive strip, 3M double-sided adhesive, and a cloth tape. The thin-walled wire is inserted into the adhesive strip and forms a U-shaped connecting line. The cloth tape is wrapped around both ends of the adhesive strip, and the 3M double-sided adhesive is attached to one side of the adhesive strip.

[0019] By adopting the above technical solution, the thin-walled wire is inserted into the adhesive strip in a U-shape, which not only ensures the reliability of the connection, but also improves the flexibility of the wiring; the two ends of the adhesive strip are wrapped with cloth-based adhesive tape to strengthen the fixation and prevent the wire from loosening; 3M double-sided tape is used to fix the adhesive strip to the vehicle body to achieve the purpose of quick bonding and installation; the overall structure is compact, highly adaptable, can stably transmit signals and is easy to install.

[0020] In summary, by eliminating components such as connector terminals and waterproof plugs, the overall structure and installation steps of the virtual pedal assembly are simplified, thereby reducing the cost of components and assembly. Attached Figure Description

[0023] See attached document Figure 1 - Appendix Figure 2 The composition, features, and advantages of the integrated injection-molded virtual pedal assembly according to this application will be described below by way of example, but all descriptions should not be construed as limiting the application in any way.

[0024] Furthermore, for any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in the accompanying drawings, this application still allows for any combination or deletion of these technical features (or their equivalents) without any technical obstacle, and thus these further embodiments according to this application should also be considered within the scope of this description.

[0025] It should also be noted that terms such as "setup" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can refer to a direct connection or an indirect connection through an intermediate medium. Unless otherwise explicitly defined, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] Reference Figures 1-2An integrated injection-molded virtual pedal assembly includes a housing assembly 1, a PCBA assembly 2, and a cover plate 3. The cover plate 3 and the housing assembly 1 are fixedly connected by welding. The PCBA assembly 2 is installed in the cover plate 3 and the housing. The housing assembly 1 includes a cable group 11, a PIN pin 122 assembly 12, and an ECU housing 13. The PIN pin 122 assembly 12 is detachably installed in the ECU housing 13, and one end of the cable group 11 is connected to the PIN pin 122 assembly 12.

[0027] During installation, the PIN pin 122 assembly 12 is first fixedly connected to the cable assembly 11, and then the PIN pin 122 assembly 12 is installed inside the ECU housing 13 to complete the fabrication of the housing assembly 1. Next, the PCBA assembly 2 is installed on the housing assembly 1, and after the cover plate 3 is fastened, the cover plate 3 and the housing assembly 1 are fixedly connected by welding, thereby completing the installation of the integrated injection-molded virtual pedal assembly. In the above installation process, connector terminals and waterproof plugs are eliminated, and only the PIN pin 122 assembly 12 is needed, which simplifies the structure and installation steps of the virtual pedal assembly, and reduces the cost of parts and assembly.

[0028] Specifically, a sealed hollow space is formed between the housing assembly 1 and the cover plate 3 for installing and accommodating the PCBA assembly 2. In this embodiment, the housing assembly 1 and the cover plate 3 are fixedly connected by laser welding, or other common welding methods can be used to form a sealed space.

[0029] Furthermore, the cable assembly 11 can consist of two electrodes, such as two round electrodes, two flat electrodes, or a combination of round and flat electrodes.

[0030] When using a combination of round electrode A and flat electrode B, one end of both electrodes is fixedly connected to one side of the ECU housing 13, and both electrodes form signal connections with the PBCA assembly via corresponding PIN pin 122 assemblies 12. The other ends of both electrodes form connection terminals for signal input. When using a combination of two round electrodes or two flat electrodes, the connection method is the same as the aforementioned combination of round electrode A and flat electrode B, only applicable to different usage scenarios.

[0031] It should be understood that, in the embodiments of this application, the circular electrode A includes a coaxial cable 111 and an end injection molding block 112. One end of the coaxial cable 111 is connected to the PCBA assembly 2 for signal transmission. The other end of the coaxial cable 111 is fixedly connected to the end injection molding block 112. Heat shrink tubing is provided on the outside of the coaxial cable 111 and the end injection molding block 112 to form a plastic coating layer.

[0032] The flat electrode B includes a thin-walled wire 113, an adhesive strip 114, 3M double-sided adhesive 115, and cloth tape 116. Both ends of the thin-walled wire 113 pass through the same end of the adhesive strip 114, forming a U-shaped connection. Simultaneously, cloth tape 116 is wrapped around both ends of the adhesive strip 114 to restrict the position of the thin-walled wire 113. 3M double-sided adhesive 115 is attached to one side of the adhesive strip 114, allowing it to be fixed to the vehicle body for positioning purposes.

[0033] Furthermore, the PIN pin 122 assembly 12 includes a plastic-coated body 121 and two sets of PIN pins 122. The plastic-coated body 121 is fixedly connected to the ECU housing 13. The pins of the two sets of PIN pins 122 are arranged in a one-to-one correspondence. Each pair of pins can be formed by bending the same pin. In this embodiment, each pair of pins can be arranged at 90 degrees so that the two sets of PIN pins 122 can form a connection signal connection with the PCBA assembly 2 and the cable group 11 respectively.

[0034] During installation, the plastic-coated body 121 can be directly fixed inside the ECU housing 13. Then, the plug-in PCBA assembly 2 and cable group 11 are installed. Next, the cover plate 3 is fastened onto the ECU housing 13. Finally, the connection is fixed by laser welding. The installation is simple and the operation steps are convenient, thus simplifying the installation process.

[0035] PCBA assembly 2 is a commonly used PCBA board for soldering corresponding components in this technical field. No improvements are made in the embodiments of this application, and therefore no detailed limitations are imposed.

[0036] In summary, the implementation principle of this application is as follows: both the PCBA assembly 2 and the PIN pin 122 assembly 12 are installed within the sealed space formed by the ECU housing 13 and the cover plate 3. One end of the cable assembly 11 extends into the ECU housing 13 and the cover plate 3, and forms a signal connection with the PCBA assembly 2 through the PIN pin 122 assembly 12. The other end of the cable assembly 11 extends out of the ECU housing 13 and the cover plate 3 for easy connection. This technical solution simplifies the virtual pedal assembly structure, facilitates assembly by workers, and reduces assembly costs. The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
