Technical Field
[0001] This utility model relates to the field of automotive warning device technology, specifically a reinforced connection structure for automotive warning devices. Background Technology
[0002] A car warning device is an important piece of equipment installed in a car to issue warning signals when the vehicle is in an abnormal situation or in a specific state, so as to ensure driving safety. Car warning devices are an important line of defense for safe driving, and can promptly remind the driver to discover and deal with vehicle problems, reducing the possibility of accidents.
[0003] However, under current technological conditions, most car warning devices on the market use a split injection molding process, molding the outer shell and the warning device connector separately, and then assembling them manually. When the vehicle is driving on bumpy roads, the outer shell and the warning device connector are easily separated or loosened due to continuous vibration and mechanical stress, which reduces the reliability of the product and makes it less practical.

[0005] In view of the shortcomings of the prior art, this utility model provides a reinforced connection structure for a car warning device to solve the problems mentioned in the background.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a reinforced connection structure for a car warning device, comprising a housing and a warning device connector injection molded inside the housing. The housing has a first connecting groove and a second connecting groove on the side facing the warning device connector. A connecting block adapted to the first connecting groove is fixedly installed on the side of the warning device connector facing the housing. Fixing posts are fixedly installed at both the upper and lower ends of the connecting block. A downward-folding hook is fixedly installed on the lower part of the connecting block near the housing. Fixing hooks arranged at equal intervals are also provided on both sides of the connecting block. Adaptation holes are reserved on the upper and lower sides of the housing. Hook grooves are reserved on both sides of the first connecting groove inside the housing. A locking block is provided at the opening at the upper part of the housing. A connector post is fixedly installed at the end of the housing away from the warning device connector. A guide strip is fixedly installed on the outer side of the connector post. A hook block is fixedly installed on the outer side of the connector post away from the housing.
[0008] With the above technical solution, when producing car warning devices, the outer shell is first injection molded, and then the warning device connector and connecting block are injection molded. At this time, the connecting block will be firmly stuck in the first connecting groove reserved inside the outer shell.
[0009] Preferably, the fixing post and the adapter hole are provided in two identical sets, and each set of the fixing post and the adapter hole is provided in two identical sets. The adapter hole is in contact with the fixing post and is wrapped around the outside of the fixing post.
[0010] The above technical solution ensures a firm connection between the outer shell and the connecting block, preventing the connecting block from separating from the inside of the outer shell. It also strengthens the connection structure between the outer shell and the alarm connector.
[0011] Preferably, there are several identical hook grooves and fixed hooks, the hook grooves and fixed hooks are fixedly connected, the hook grooves wrap around the outside of the fixed hooks, and the shape of the hook grooves is the same as the shape of the fixed hooks.
[0012] By employing the aforementioned technical solution, which features a plurality of identical hook grooves and fixing hooks, and designing the hook grooves to enclose the outer side of the fixing hooks, it is ensured that the connecting block is firmly anchored within the first connecting groove, preventing the connecting block from detaching from the first connecting groove, thereby enhancing the connection strength between the outer shell and the warning device connector.
[0013] Preferably, the number of the second connecting slots is twice that of the first connecting slots. The first connecting slots and the two second connecting slots are interconnected. The combined cross-section of the first connecting slots and the second connecting slots has an "L" shape. Two identical downward hooks are provided, and the two downward hooks are hooked inside the second connecting slots.
[0014] The above technical solution, with the design of the lower fold hook located inside the second connecting groove, ensures that the first connecting groove can tightly hook the outer shell, further improving the connection strength.
[0015] Preferably, the cross-section of the fixing hook is composed of a first inclined side, a second inclined side, and a circular arc side. The first inclined side and the second inclined side have the same inclination angle. The circular arc side is located at the connection between the first inclined side and the second inclined side. The angle between the first inclined side and the connecting block is 30°.
[0016] The above technical solution effectively avoids the separation of the outer shell and the alarm connector, and also reduces the reassembly process, which saves costs and improves the connection strength between the outer shell and the alarm connector.
[0017] Preferably, the connecting block is completely submerged inside the first connecting groove, and the outer shell and the alarm connector are fixedly connected.
[0018] The above technical solution ensures that there are no gaps at the connection between the outer shell and the alarm connector, and prevents the outer shell and the alarm connector from separating during use. It also avoids gaps between the outer shell and the alarm connector that could cause them to shake and produce abnormal noises.
[0019] Compared with the prior art, the present invention provides a reinforced connection structure for a car warning device, which has the following beneficial effects:
[0020] This reinforced connection structure for car warning devices utilizes a multi-stage injection molding process. First, the outer shell is injection molded, then the outer shell, warning device connector, and connecting block are integrally injection molded. This effectively prevents the outer shell from separating from the warning device connector, reducing reassembly steps and saving costs. The step-by-step injection molding of the outer shell and warning device connector prevents separation and avoids gaps that could cause shaking and noise. The design of the hook groove and fixing hook, the adapter hole and fixing post, and the downward folding hook ensures the connecting block is firmly anchored inside the first connecting groove, preventing it from detaching. This enhances the connection strength between the outer shell and the warning device connector, preventing separation or loosening due to vehicle vibrations. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Example 1:
[0031] like Figure 1-7 As shown, the present invention provides a reinforced connection structure for a car warning device, including a housing 1 and a warning device connector 2 injection molded inside the housing 1. The side of the housing 1 facing the warning device connector 2 has a first connecting groove 3 and a second connecting groove 14. The side of the warning device connector 2 facing the housing 1 is fixedly installed with a connecting block 4 that matches the first connecting groove 3. The upper and lower ends of the connecting block 4 are fixedly installed with fixing posts 6. The lower part of the connecting block 4 near the housing 1 is fixedly installed with a downward hook 5. The two sides of the connecting block 4 are also provided with fixing hooks 7 arranged at equal intervals. The upper and lower sides of the housing 1 have pre-drilled fitting holes 8. The inside of the housing 1 has pre-drilled hook grooves 13 on both sides of the first connecting groove 3. The upper opening of the housing 1 is provided with a locking block 9. The end of the housing 1 away from the warning device connector 2 is fixedly installed with a connector post 10. The outer side of the connector post 10 is fixedly installed with a guide strip 11. The outer side of the connector post 10 away from the housing 1 is fixedly installed with a hook block 12. The advantage is that when producing the car warning device, the outer shell 1 is first injection molded, and then the outer shell 1, the warning device connector 2 and the connecting block 4 are integrally injection molded. At this time, the connecting block 4 will be firmly stuck in the first connecting groove 3 reserved inside the outer shell 1.
[0032] Example 2:
[0033] like Figure 2-7 As shown, as an improvement to the previous embodiment, the connection between the housing and the alarm connector is further strengthened.
[0034] Specifically, both the fixing post 6 and the adapter hole 8 are provided in two identical sets, with each set containing two identical fixing posts 6 and adapter holes 8. The adapter hole 8 abuts against the fixing post 6 and is wrapped around the outside of the fixing post 6. The advantage is that it ensures a firm connection between the outer shell 1 and the connecting block 4, preventing the connecting block 4 from separating from the inside of the outer shell 1, and also strengthens the connection structure between the outer shell 1 and the alarm connector 2.
[0035] Specifically, several identical hook grooves 13 and fixed hooks 7 are provided, and the hook grooves 13 and fixed hooks 7 are fixedly connected. The hook grooves 13 wrap around the outside of the fixed hooks 7, and the shape of the hook grooves 13 is the same as that of the fixed hooks 7. The advantage is that by providing several identical hook grooves 13 and fixed hooks 7, and by designing the hook grooves 13 to wrap around the outside of the fixed hooks 7, it can be ensured that the connecting block 4 can be firmly anchored inside the first connecting groove 3, and it can also prevent the connecting block 4 from detaching from the inside of the first connecting groove 3, thereby improving the connection strength between the outer shell 1 and the warning device connector 2.
[0036] Specifically, the number of second connecting slots 14 is twice that of the first connecting slots 3. The first connecting slots 3 and the two second connecting slots 14 are interconnected. The combined cross-section of the first connecting slots 3 and the second connecting slots 14 has an "L" shape. Two identical lower fold hooks 5 are provided, and the two lower fold hooks 5 are hooked inside the second connecting slots 14. The advantage is that the design of the lower fold hooks 5 being located inside the second connecting slots 14 ensures that the first connecting slot 3 can tightly hook onto the outer shell 1, further improving the connection strength.
[0037] Specifically, the cross-section of the fixing hook 7 consists of a first inclined side 701, a second inclined side 702, and a rounded side 703. The inclination angles of the first inclined side 701 and the second inclined side 702 are the same, and the rounded side 703 is located at the connection between the first inclined side 701 and the second inclined side 702. The angle between the first inclined side 701 and the connecting block 4 is 30°. The advantage is that it effectively prevents the housing 1 from separating from the alarm connector 2, and also reduces the reassembly process, saving costs and improving the connection strength between the housing 1 and the alarm connector 2.
[0038] Specifically, the connecting block 4 is completely submerged inside the first connecting groove 3, and the outer shell 1 and the alarm connector 2 are fixedly connected. The advantage is that it ensures that there are no gaps at the connection between the outer shell 1 and the alarm connector 2, ensuring that the outer shell 1 and the alarm connector 2 will not separate during use, and also avoiding the situation where gaps appear between the outer shell 1 and the alarm connector 2, causing them to shake and produce abnormal noises.
[0039] Working principle: During production, the outer shell 1 is first injection molded, and then the outer shell 1, the warning connector 2, and the connecting block 4 are integrally injection molded. At this time, the connecting block 4 will be firmly locked in the first connecting groove 3 reserved inside the outer shell 1, and the fixing post 6 will also be locked into the reserved adapter hole 8. Through the design that the hook groove 13 and the fixing hook 7 are both provided with several identical ones, and the hook groove 13 is wrapped around the outside of the fixing hook 7, it can be ensured that the connecting block 4 can be firmly anchored inside the first connecting groove 3, and it can also prevent the connecting block 4 from detaching from the inside of the first connecting groove 3, thereby achieving... The improved connection strength between the outer shell 1 and the alarm connector 2 is achieved through the design of the lower hook 5 located inside the second connecting groove 14. This ensures that the first connecting groove 3 can tightly hook the outer shell 1, further enhancing the connection strength and effectively preventing the outer shell 1 from separating from the alarm connector 2. It also reduces the reassembly process, saving costs. Furthermore, the step-by-step injection molding of the outer shell 1 and the alarm connector 2 prevents them from separating and avoids gaps between them that could cause them to shake and produce abnormal noises.
