Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive instrument technology, specifically an automotive instrument with good stability. Background Technology
[0002] The car dashboard is the core device that centrally displays the vehicle's operating status. It is mainly used to monitor and provide feedback on the working status of various systems. Located in front of the driver, its core functions include real-time display of basic data such as vehicle speed, engine speed, fuel level, and coolant temperature. It also uses indicator lights and warning lights to indicate faults or abnormal conditions. The car dashboard consists of a display screen, front and rear housings, mounting brackets, circuit boards, etc. In order to facilitate quick assembly without additional tools and improve production efficiency, the front and rear housings are connected by snap-fit slots. Therefore, a robust and stable snap-fit structure for the car dashboard needs to be designed to prevent loosening and abnormal noises. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a car instrument with good stability in order to address the above-mentioned defects and solve the problems mentioned in the background art.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A car instrument with good stability includes a rear housing and a front housing. Connectors are evenly arranged around the periphery of the outer walls at both ends of the rear housing. A through hole is opened on the connector. A connecting arm corresponding to the connector is arranged around the periphery of the rear end face of the front housing. A locking block is arranged on the rear end face of the connecting arm. A locking groove is formed between the locking block and the connecting arm. One end of the connecting arm abuts against the inner wall of one end of the through hole. The locking block and the connecting arm form a locking groove that abuts against the edge of the through hole on the rear end face of the connector. A clamping member is arranged on the rear end face of the connector to drive the locking block, the connecting arm and the connector to generate a clamping force. The end of the clamping member away from the connector abuts against the locking block. When the locking block and the connector are engaged, the locking block drives the clamping member to undergo elastic deformation. The reverse force of the clamping member drives the locking block, the connecting arm and the connector to fit tightly together.
[0005] Furthermore, the through hole has a rectangular cross-section. When the instrument rear housing and the instrument front housing are assembled, the locking block passes through the through hole and extends to the rear end of the connector.
[0006] Furthermore, the end of the card block away from the clamping member is provided with a driving slope.
[0007] Furthermore, the clamping member includes a horizontal section and an inclined section. One end of the horizontal section is fixedly connected to the rear end face of the connector, and one end of the inclined section is fixedly connected to the other end of the horizontal section. The inclined section gradually slopes downward from one end of the horizontal section to one end of the locking block, and an obtuse angle is formed between the horizontal section and the inclined section.
[0008] Furthermore, the distance between the inner wall of the inclined section and the inner wall of the through hole is smaller than the outer diameter of the card block.
[0009] Furthermore, mounting portions are symmetrically arranged at both ends of the instrument's rear housing, and mounting holes are provided on the mounting portions. The mounting portions and connectors are arranged alternately at intervals.
[0010] The beneficial effects of this utility model are:
[0011] This utility model utilizes a combination of connectors, through holes, connecting arms, locking blocks, locking slots, and clamping components. During the assembly of the front and rear housings of the instrument, the locking block enters the through hole and is squeezed by the inner wall of the through hole, causing the connecting arm and locking block to undergo elastic deformation and deflection. The locking block also squeezes the clamping component, causing it to undergo elastic deformation until the locking block passes through the through hole and moves to the rear end of the connector. The squeezing force on the locking block disappears, and the connecting arm and locking block return to their original position, causing the locking slot to engage with the connector. The clamping component is continuously limited by the locking block, and the resulting reverse force ensures that the locking slot and the connector are tightly and firmly fitted together, making the installation more secure and stable, and less prone to loosening or abnormal noise.

[0012] The foregoing and other objects, features and advantages of this invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.
[0013] Figure 1 This is a front view of the present utility model.
[0014] Figure 2 This is a partial sectional view from the side of this utility model.
[0015] The components are: 1. Rear housing of the instrument; 2. Front housing of the instrument; 3. Connecting parts; 301. Through hole; 4. Connecting arm; 5. Locking block; 6. Locking groove; 7. Clamping parts; 701. Horizontal section; 702. Inclined section; 8. Mounting part; 801. Mounting hole. Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] Reference Figure 1-2As shown, a stable automotive instrument panel includes a rear housing 1 and a front housing 2. A mounting bracket, display screen, circuit board, etc., are provided between the front housing 2 and the rear housing 1 to display vehicle driving information and vehicle status. This is existing technology and will not be described in detail here. Connectors 3 are evenly distributed around the periphery of the outer walls at both ends of the rear housing 1. The cross-section of the connector 3 is rectangular, and a through hole 301 is provided on the connector 3. The through hole 301 also has a rectangular cross-section. A connecting arm 4 corresponding to the connector 3 is provided around the periphery of the rear end face of the front housing 2. A locking block 5 is provided on the rear end face of the connecting arm 4. The connecting arm 4, locking block 5, and front housing 2 are integrally formed. A groove 6 is formed between the locking block 5 and the connecting arm 4. One end of the connecting arm 4 abuts against the inner wall of one end of the through hole 301. The groove 6 formed by the locking block 5 and the connecting arm 4 abuts against the edge of the through hole 301 on the rear end face of the connector 3. When the housing 1 and the front housing 2 of the instrument are assembled, the locking block 5 penetrates through the through hole 301 and extends to the rear end of the connector 3. The end of the locking block 5 away from the clamping member 7 is provided with a driving slope 501. When the rear housing 1 and the front housing 2 of the instrument are assembled, when the locking block 5 enters the through hole 301, the driving slope 501 abuts against the edge at the inlet of the through hole 301, thereby driving and squeezing the locking block 5. This causes the locking block 5 and the connecting arm 4 to undergo elastic deformation and be squeezed inside the through hole 301. Only when the locking block 5 passes through the through hole 301 and moves to the rear end of the connector 3, the squeezing force on the locking block 5 disappears, the connecting arm 4 and the locking block 5 reset, and its locking groove 6 abuts against the edge of the through hole 301 on the rear end face of the connector 3, thereby engaging with the connector 3. The connecting arm 4 abuts against the inner wall of one end of the through hole 301, thereby forming an assembly and fixation between the front housing 2 and the rear housing 1 of the instrument. This allows for quick assembly without additional tools, thereby improving production efficiency.
[0018] The rear end face of the connector 3 is provided with a clamping element 7 that drives the locking block 5, connecting arm 4 and connector 3 to generate a clamping force. The end of the clamping element 7 away from the connector 3 abuts against the locking block 5. When the locking block 5 and connector 3 are engaged, the locking block 5 drives the clamping element 7 to undergo elastic deformation. The reverse force of the clamping element 7 drives the locking block 5, connecting arm 4 and connector 3 to fit tightly together. The clamping element 7 includes a horizontal section 701 and an inclined section 702. One end of the horizontal section 701 is fixedly connected to the rear end face of connector 3. One end of the inclined section 702 is fixedly connected to the other end of the horizontal section 701. The inclined section 702 gradually slopes downward from one end of the horizontal section 701 to one end of the locking block 5. An obtuse angle is formed between the horizontal section 701 and the inclined section 702. The inner wall of the inclined section 702 is close to the inner wall of the through hole 301. The spacing is smaller than the outer diameter of the locking block 5. When the locking block 5 passes through the through hole 301, one end of the locking block 5 abuts against the inclined section 702. As the locking block 5 moves, it continuously squeezes the inclined section 702, causing the inclined section 702 and the horizontal section 701 to undergo elastic deformation. Only when the locking groove 6 of the locking block 5 engages with the connecting piece 3, one end of the inclined section 702 still abuts against the locking block 5. The locking block 5 continuously applies a pushing force to the inclined section 702. The opposing force generated by the force on the inclined section 702 and the horizontal section 701 drives the locking groove 4 and the connecting piece 3 to fit together firmly, making the installation of the connecting arm 4 and the locking block 5 more secure and stable. It is not easy for loosening and abnormal noise to occur due to a large assembly gap, making the installation between the front housing 2 and the rear housing 1 of the instrument more secure and stable.
[0019] The instrument rear housing 1 has mounting parts 8 symmetrically arranged at both ends. The mounting parts 8 have mounting holes 801. The mounting parts 8 and the connectors 3 are arranged alternately. The mounting parts 8 cooperate with the mounting holes 801 to fix the instrument panel inside the instrument panel.
[0020] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
