Description

Technical Field

[0001] This utility model relates to the field of automotive host technology, specifically to an automotive host structure and molding equipment with hooks and screws. Background Technology

[0002] Currently, automotive infotainment systems are increasingly trending towards networking, voice recognition, and high-speed connectivity. These high performance features rely heavily on Bluetooth and Wi-Fi modules. However, these two modules are highly susceptible to interference from external sources and components on the internal printed circuit board (PCB). To prevent signal loss and instability in Wi-Fi and Bluetooth, these modules need to be shielded against interference. Traditional methods involve designing a shielding sleeve around the entire PCB for interference protection. While this isolates external interference, it fails to shield against interference from internal components on the integrated PCB, thus its anti-interference effect is still insufficient.

[0003] A search revealed that prior art CN213280383U discloses an automotive host structure, including an automotive host housing, a PCBA installed within the housing, and a shielding box installed within the housing. The shielding box houses in-vehicle Bluetooth and Wi-Fi modules, and has wiring holes through which the wiring of the in-vehicle Bluetooth and Wi-Fi modules passes and connects to the PCBA. This automotive host structure can prevent electromagnetic interference from components on the PCBA to the in-vehicle Bluetooth and Wi-Fi modules, and also prevents interference from the external environment, thereby achieving stable output of Bluetooth and Wi-Fi signals.

[0004] However, the above-mentioned automotive host structure has the following problems in use: the front cover and rear cover of the shielding box are fastened together by a snap-fit ​​structure to form a cavity for accommodating the vehicle Bluetooth and WIFI modules. The ribs set in the slot are mostly thin in size to ensure that they are elastic and facilitate the snap-fit ​​release action. They are prone to breakage when the snap-fit ​​is removed. After breakage, it will seriously affect the stable installation of the cover. At the same time, after breakage, the entire front cover of the shielding box needs to be replaced, which greatly increases the cost of use. Utility Model Content

[0005] The purpose of this utility model is to provide a car host structure and molding equipment with hooks and screws to solve the problem that the front and rear cover plates of the shielding box in the existing car host are unstable to install, and that the entire shielding box needs to be replaced after the slot rib plate breaks, which seriously increases the cost of use.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a car host structure with hooks and screws, including a car host housing, a printed circuit board is provided inside the car host housing, and an installation mechanism is also included.

[0007] The installation mechanism includes a shielding box, a cover plate, a first hook, a second hook, a locking screw, a T-shaped slider, and a fixing device. The shielding box is installed inside the vehicle's main unit housing via the fixing device. It houses a vehicle-mounted Bluetooth and Wi-Fi module. The Wi-Fi module's wiring passes through a wiring cavity on the shielding box and connects to the printed circuit board. The cover plate is detachably mounted on the front side of the shielding box. The first hook is detachably connected to the shielding box and located on both sides of the shielding box. The second hook is fixedly connected to the cover plate and slidably connected to the first hook. The locking screw is slidably connected to the top support arm of the second hook and the first hook, passes through the first hook, and is threadedly connected to the bottom support arm of the second hook. The T-shaped slider is detachably connected to the cover plate and can slide along a T-shaped groove on the shielding box. The fixing device is located on both sides of the shielding box.

[0008] The number of T-shaped sliders is two, and they are symmetrically arranged on the side of the cover plate away from the second hook.

[0009] The printed circuit board is installed at the inner bottom of the vehicle's main housing.

[0010] The fixing device includes a fixing plate and fastening screws. The fixing plate is integrally formed with the shielding box and is disposed on both sides of the shielding box. The fastening screws pass through the mounting holes of the fixing plate and are threadedly connected to the vehicle main unit housing.

[0011] The installation mechanism also includes a protective cover, which is detachably connected to the vehicle host housing and covers the outside of the shielding box and the cover plate, and is provided with a mating groove for the WIFI module's wiring to pass through.

[0012] One type of molding equipment can be used for component processing of the automotive mainframe structure with hooks and screws.

[0013] This utility model discloses a car host structure with hooks and screws. The shielding box is fixed to the inner wall of the car host housing by a fixing device. When installing the cover plate, the right T-shaped slider is aligned with the non-penetrating T-shaped groove on the shielding box and pushed in. The cover plate is further pushed until the right T-shaped slider slides to its limit position. At this point, the second hook slides and abuts against the first hook, which just achieves the vertical hole alignment. Then, the locking screw is directly installed for fixation, thereby installing the cover plate on the shielding box. Compared with the buckle structure in the prior art, the cover plate installation structure of this application will not damage the shielding box or cover plate during installation or disassembly. At the same time, the first hook, second hook, T-shaped slider and locking screw can be replaced individually or simultaneously after damage, without the need to replace the entire shielding box or cover plate. This solves the problem of unstable installation of the front and rear cover plates of the shielding box in existing car hosts, and the need to replace the entire shielding box component after the slot rib plate breaks, which seriously increases the cost of use.

[0022] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1:

[0024] like Figures 1 to 5 As shown, where Figure 1 This is a schematic diagram of the overall structure of the car's main unit, including hooks and screws. Figure 2 This is a structural schematic diagram of cover plate 105. Figure 3 This is a structural schematic diagram of the shielding box 103. Figure 4 This is a structural schematic diagram of the second hook 107. Figure 5 This is a schematic diagram of the T-shaped slider 109. This utility model provides a car host structure with hooks and screws: it includes a car host housing 101, a printed circuit board 102, and a mounting mechanism. The mounting mechanism includes a shielding box 103, a cover plate 105, a first hook 106, a second hook 107, a locking screw 108, a T-shaped slider 109, and a fixing device. The fixing device includes a fixing plate 110 and a fastening screw 111. The aforementioned solution solves the problem of unstable installation of the front and rear cover plates of the shielding box in existing car host systems, and the need to replace the entire shielding box component after the slot rib plate breaks, which seriously increases the cost of use. It is understood that the aforementioned solution can improve the stability of the shielding box assembly and disassembly, and help reduce the cost of use.

[0025] In this embodiment, a printed circuit board 102 is disposed inside the vehicle main unit housing 101. The vehicle main unit housing 101 is provided with through holes for the working lines of corresponding working components.

[0026] The shielding box 103 is installed inside the car host housing 101 by the fixing device. It houses a vehicle Bluetooth and Wi-Fi module 104. The wiring of the Wi-Fi module 104 passes through the wiring cavity on the shielding box 103 and connects to the printed circuit board 102. The cover plate 105 is detachably mounted on the front side of the shielding box 103. The first hook 106 is detachably connected to the shielding box 103 and located on both sides of the shielding box 103. The second hook 107 is fixedly connected to the cover plate 105 and slidably connected to the first hook 106. The locking screw 108 is slidably connected to the top support arm of the second hook 107 and the first hook 106, passes through the first hook 106, and is threadedly connected to the bottom support arm of the second hook 107. The T-shaped slider 109 is detachably connected to the cover plate 105 and can slide in the T-shaped groove on the shielding box 103. The fixing device is located on both sides of the shielding box 103. The shielding box 103 has a through hole on its lower left side for wiring, allowing the wiring of the internal WIFI module 104 to pass through and connect to the printed circuit board 102. The cover plate 105 has multiple ventilation holes to facilitate airflow and heat dissipation for the internal electronic components. Furthermore, after installation, the shielding box 103 ensures a sufficient distance between the vehicle Bluetooth, the WIFI module 104, and the printed circuit board 102, further enhancing resistance to interference from components on the printed circuit board 102 on the vehicle Bluetooth and WIFI module. To mitigate electromagnetic interference generated by the FI module 104, a non-penetrating T-shaped groove is provided on the bottom side of the shielding box 103 from left to right, facilitating the placement of the T-shaped slider 109. The T-shaped slider 109 is fixed to the cover plate 105 by countersunk bolts and engages with the T-shaped groove. The first hook 106 is fixed by bolts, with the bolts arranged from the inside to the outside of the shielding box 103. The first hook 106 has a vertical through hole. The second hook 107 is fixed to the cover plate 105 by bolts, with a vertical through hole on its top support arm and a through threaded hole on its bottom support arm. The locking screw 108 is T-shaped and can be turned with an Allen wrench, with an external threaded end at the bottom.

[0027] Secondly, there are two T-shaped sliders 109, which are symmetrically arranged on the side of the cover plate 105 away from the second hook 107. The T-shaped sliders 109 limit the installation of the lower end of the cover plate 105 and realize the sliding engagement and hole alignment of the first hook 106 and the second hook 107.

[0028] Then, the printed circuit board 102 is installed on the inner bottom of the vehicle main unit housing 101. The printed circuit board 102 is installed on the inner bottom of the vehicle main unit housing 101, and the shielding box 103 is installed on the inner side wall.

[0029] Finally, the fixing plate 110 is integrally formed with the shielding box 103 and is disposed on both sides of the shielding box 103; the fastening screw 111 passes through the mounting hole of the fixing plate 110 and is threadedly connected to the vehicle main unit housing 101. The fixing plate 110 is provided with a countersunk hole to facilitate the fastening screw 111 to pass through and connect to the vehicle main unit housing 101 for installation, and the fastening screw 111 can be turned by an Allen wrench.

[0030] When using this utility model to solve the problem of unstable installation of the front and rear cover plates of the shielding box in existing automotive head units, and the need to replace the entire shielding box component after the slot rib plate breaks, which seriously increases the cost of use, firstly, the shielding box 103 can be directly fixed to the inner wall of the automotive head unit housing 101 by the fixing device. Then, when installing the cover plate 105, the right-side T-shaped slider 109 is aligned with the non-penetrating T-shaped groove on the shielding box 103 and pushed in. Further pushing the cover plate 105, when the right-side T-shaped slider 109 slides to its limit position, at this time, the second hook 107 and the first hook 106 slide and abut, just achieving vertical hole alignment. Then, the locking screw is directly installed. 108 is used to fix the cover plate 105 onto the shielding box 103. Compared with the snap-fit ​​structure in the prior art, the cover plate 105 mounting structure of this application will not damage the shielding box 103 or the cover plate 105 during installation or removal. At the same time, the first hook 106, the second hook 107, the T-shaped slider 109 and the locking screw 108 are all detachable structures. They can be replaced individually or simultaneously after damage, without having to replace the entire shielding box 103 or the cover plate 105. This solves the problem of unstable installation of the front and rear cover plates of the shielding box in the existing automotive host, and the need to replace the entire shielding box after the slot rib plate breaks, which seriously increases the cost of use.
