Description

Technical Field

[0001] This utility model relates to the field of vehicle system equipment technology, and in particular to a handle for a vehicle system host module. Background Technology

[0002] Vehicle-mounted system head units typically employ a modular design, with each functional module secured within the chassis via a module panel. Insertion and removal are facilitated by a pull-out handle. A pull-out handle is a specialized tool or component used to assist in the installation or removal of vehicle-mounted electronic devices (such as head units, navigation modules, and audio modules). The pull-out handle provides a point of leverage through leverage or mechanical structures, helping users more easily remove modules from their fixed positions and avoiding damage to interfaces caused by directly pulling cables or prying.

[0003] Currently, most pull-up handles on the market have the following technical defects: 1. Complex structure and poor reliability Traditional handles employ a multi-component assembly structure (such as springs and clips), requiring high machining precision, resulting in high production costs and a persistently high failure rate. For example, some handles experience module locking failure due to spring failure or clip breakage. The complex structure is also prone to mechanical interference with components such as the front crossbeam of the chassis during frequent insertion and removal, further accelerating wear.

[0004] 2. Limited installation space hinders module expansion and reduces flexibility. The existing handle needs to be fixed to a specific position on the module panel through preset holes, which cannot accommodate the installation requirements of modules of different sizes and hinders system expansion. When the module panel needs to be repositioned for upgrades, the handle may not be able to align with the stress point of the front crossbeam of the chassis, causing the pull-out assist function to fail.

[0005] 3. The lever design is unreasonable, making operation difficult. While some handles are of moderate length, their fulcrum is far from the contact surface between the module panel and the front crossbeam of the chassis, resulting in insufficient torque and requiring users to apply considerable force to remove the module. Handles that are too long may obstruct or interfere with the connectors during rotation, affecting the smoothness of insertion and removal. Handles that are too large will protrude and occupy space at the front of the chassis, hindering the installation of adjacent modules. Utility Model Content

[0006] The purpose of this invention is to provide a vehicle-mounted system host module pull handle that is simple in structure, flexible in installation, and easy to operate.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A vehicle-mounted system host module for the handlebar, the module being housed within a chassis. The module enters the chassis along the module guide rail, and the module connector on the end of the module entering the chassis is correspondingly connected to the motherboard connector inside the chassis; the module is provided with a module panel at the end of the module near the front crossbeam of the chassis. Pull-out components, The pull-out aid is installed on a square slot in the module panel by screws, and the end of the pull-out aid facing the inside of the chassis is close to the front crossbeam of the chassis. When the pull-out assisting component is moved, it rotates and presses against the front crossbeam of the chassis, forming a lever structure with the pull-out assisting mechanism and the front crossbeam of the chassis as the fulcrum. This causes the module connector to disconnect from the motherboard connector, and then the pull-out assisting component is pulled to remove the module from the chassis along the module guide rail.

[0008] Preferably, the lifting aid component is I-shaped and includes a connecting part, a rotating part, and a hand-held part. The end face of the connecting part is close to the front crossbeam of the chassis. The connecting part and the hand-held part are connected through the rotating part. A through hole is provided on the rotating part for connecting the lifting aid component to the module panel.

[0009] Preferably, a bending portion is provided on the upper part of the square groove in the module panel, radially outward along the upper end face cross-section of the square groove; Similarly, a second bending section is provided at the lower part of the square groove along the radial outer side of the lower cross section of the square groove.

[0010] Preferably, the first bending part and the second bending part are provided with holes corresponding to the through hole one opened on the rotating part, and the screw passes through the second bending part, the rotating part, and the first bending part to connect the pull-out aid to the module panel.

[0011] Preferably, the hole includes a threaded hole on the first bending portion and a through hole on the second bending portion.

[0012] Preferably, the module panel is provided with a panel connector for external interface expansion.

[0013] Preferably, the pull-out aid component is machined or cast.

[0014] The beneficial effects of this utility model are: (1) This utility model discloses a vehicle system host module pull-out handle, which has a simple structure and includes a pull-out component. The pull-out component is installed on the module panel by screw connection. Compared with the multi-part assembly structure in the prior art, this connection method is simple and stable, does not require high-precision processing, and reduces production costs. A square groove is opened on the module panel. The end of the pull-out component facing the inside of the chassis through the square groove is close to the front crossbeam of the chassis. When in use, it is only necessary to turn the pull-out component clockwise or counterclockwise. The pull-out component rotates and presses against the front crossbeam of the chassis, forming a lever structure with the pull-out mechanism and the front crossbeam of the chassis as the fulcrum. This disconnects the module connector from the motherboard connector, and then pulls the pull-out component to pull the module out of the chassis along the module guide rail. The lever principle is applied properly. The handle is small and makes the operation time-saving and labor-saving.

[0015] (2) This utility model discloses a vehicle system host module pull-out handle. The module panel serves as an intermediary when pulling out the module. The lever force of the pull-out handle rotation is directly transmitted to the module through the panel, realizing the quick pull-out of the module. A square groove is designed on the module panel. The square groove can be designed at any position on the module panel according to the needs of the pull-out module, such as making the square groove horizontally, thereby realizing the flexibility of the installation position of the pull-out handle.

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0018] Example: This embodiment describes a handlebar structure for a vehicle-mounted system host module.

[0019] As attached Figure 1 , 2 As shown, Figure 1 This is a three-dimensional structural diagram of a preferred embodiment of the handlebar of a vehicle-mounted system host module according to the present invention. Figure 2 This is another angled schematic diagram of the auxiliary handle of the vehicle system host module shown in this utility model. An auxiliary handle for a vehicle system host module includes: an auxiliary pulling component 3, which is mounted on a square slot 11 in the module panel 7 via screws 10. One end of the auxiliary pulling component 3 facing the inside of the housing 1 is close to the front crossbeam 2 of the housing. When the auxiliary pulling component 3 is pulled, it rotates and presses against the front crossbeam 2 of the housing, forming a lever structure with the point where the auxiliary pulling component and the front crossbeam 2 press against each other as fulcrums. This disconnects the module connector 6 from the motherboard connector 9, and subsequently, the auxiliary pulling component 3 is pulled to remove the module 4 from the housing 1 along the module guide rail 5.

[0020] Module 4 is installed inside chassis 1. Module 4 enters chassis 1 along module guide rail 5. Module connector 6 on one end of module 4 enters chassis 4 and is connected to motherboard connector 9 inside chassis 1. Module panel 7 is provided on one end of module 4 near the front crossbeam 2 of chassis. Panel connector 8 for external interface expansion is provided on module panel 7. The lifting aid component 3 is machined or cast. The module panel and the module can be connected by screws.

[0021] This invention uses a screw connection method to connect the pull-out aid component to the module via the module panel. Compared with the multi-part assembly structure in the prior art, this connection method is simple and easy to operate; moreover, the production of the pull-out aid component does not require high-precision machining, which greatly reduces production costs.

[0022] This utility model does not improve the vehicle system host module. The vehicle system host is well known to those skilled in the art, so it will not be described in detail in this utility model.

[0023] like Figure 3 As shown, Figure 3 This is a schematic diagram of the pull-out aid component shown in this utility model. Figure 4This is a schematic diagram of the fulcrum when the lifting aid component rotates, as shown in the preferred embodiment. In the preferred embodiment, the lifting aid component 3 is "I" shaped and includes a connecting part 3-1, a rotating part 3-2, and a handheld part 3-3. The end face of the connecting part 3-1 is close to the front crossbeam 2 of the chassis, and the connecting part 3-1 and the handheld part 3-3 are connected through the rotating part 3-2. A through hole 12 for connecting the lifting aid component 3 to the module panel 7 is provided on the rotating part 3-2.

[0024] The overall structure of this pull-out aid is simple. Its "I"-shaped design meets the requirements for connection and gripping operation. When the pull-out aid is turned, the rotating part acts as a lever, and the connecting part abuts against the front crossbeam of the chassis. The abutting point serves as the fulcrum for the lever's movement. After rotation, the module connector is disconnected from the motherboard connector. This "I"-shaped pull-out aid forms a good lever structure. With the fulcrum resting on the front crossbeam of the chassis, the torque is sufficient, making it easy to pull out the module with minimal effort. It has good pull-out functionality and does not obstruct other modules.

[0025] To improve the stability of the connection between the lifting aid and the module, this invention provides a bending portion 13 radially outward along the upper end face of the square groove 11 at its upper part; similarly, a bending portion 2 14 is provided radially outward along the lower cross-section of the square groove 11 at its lower part. The bending portion 13 and the bending portion 2 14 are provided with holes corresponding to the through hole 12 on the rotating part 3-2. The holes include a threaded hole 13-1 on the bending portion 13 and a through hole 2 14-1 on the bending portion 2 14.

[0026] In this embodiment, the diameter of the first through hole is Φ2.6mm; the threaded hole 13-1 on the first bend is an M2.5 threaded hole, and the diameter of the second through hole 14-1 on the second bend is Φ2.6mm; the screw 10 is an M2.5×20 screw. The screw 10 passes through the second bend 14, the rotating part 3-2, and the first bend 13 to connect the pull-out member 3 to the module panel 7. The installation method is simple and secure.

[0027] The square groove design in this invention improves the connection between the pull-out aid and the module through the two bends on the directional groove. Furthermore, the module panel acts as an intermediary during module pull-out, allowing the lever force from the pull-out handle's rotation to be directly transmitted to the module, thus enabling module removal. The square groove, located on the module panel, can be positioned arbitrarily according to the needs of the pull-out module. For example, under otherwise unchanged conditions, the square groove can be horizontally moved, making the pull-out handle's position more flexible. When moving the position, it is only necessary to ensure that the pull-out handle does not interfere with other components.

[0028] Combined with appendix Figure 5 As shown, Figure 5This diagram illustrates the rotating state of the handlebar of a vehicle-mounted system's main module. Working principle: The lifting aid component 3 is installed onto the module panel 7 using screws 10. Because the handle is small in size, it does not need to be repeatedly disassembled. In use, rotating the pull-out aid component clockwise or counterclockwise will cause one end of the connecting part to press against the front crossbeam of the chassis, forming a lever structure. Under the action of the lever principle, the module connector is disconnected from the motherboard connector, and the module is pulled out along the module guide rail by the pull-out aid component.

[0029] The vehicle system host module auxiliary handle designed in this utility model has a simple overall structure and small size. It will not obstruct the connector or other module components. The lever principle of the handle is properly applied, which has strong auxiliary function, saves time and effort, and the installation position of the auxiliary handle is more flexible and adaptable. It can be adapted to existing vehicle system host modules and can also meet the needs after the module is upgraded.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
