[0028] The utility model is described in detail below in conjunction with the accompanying drawings.
[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0030] Example 1
[0031] like Figure 1-3As shown, a voice alarm device for a rear-mounted vehicle trunk lid not being closed comprises a position detector and a voice announcer, wherein the position detector comprises a proximity switch 3 and a sensing element 4, the proximity switch 3 is mounted on a box body 1 of the rear-mounted vehicle trunk, the sensing element 4 is mounted on a lid body 2 of the rear-mounted vehicle trunk, the voice announcer is mounted on a cab, the proximity switch 3 and the voice announcer are connected via an electric wire 6, and when the position detector detects that the box body 1 is separated from the lid body 2, the voice announcer issues a voice alarm.
[0032] Those skilled in the art can understand that a rear-pressing truck is a rear-loaded compression garbage transport truck, and the trunk of the rear-pressing truck is a box-shaped structure arranged behind the cab of the rear-pressing truck. The trunk of the rear-pressing truck mainly includes a box body 1 for placing garbage, and a cover body 2 located at the opening of the box body 1. For common rear-pressing trucks, the cover body 2 is usually located at the rear of the rear-pressing truck and is hinged or slidably connected to the box body 1; in particular, when the trunk of the rear-pressing truck is in a closed state, the cover body 2 is close to the box body 1. When the trunk of the rear-pressing truck needs to be opened, the hydraulic pushing device can be started to rotate or slide the cover body 2 upward. At this time, the cover body 2 is partially separated from the box body 1.
[0033] Those skilled in the art can understand that the proximity switch 3 is a position switch that can transmit control instructions without direct mechanical contact with moving parts, and the sensing element 4 is a component used to switch the working state of the proximity switch 3, which is generally made of metal; when the sensing element 4 is close to or away from the sensing area of the proximity switch 3, the proximity switch 3 can issue different control instructions, which can be transmitted to the voice announcer in the form of electrical signals, so that the voice announcer can switch between the two states of silent and loop playback of the alarm voice.
[0034] Specifically, the proximity switch 3 and the sensing element 4 can be installed on the box body 1 and the cover body 2 of the rear-pressure trunk respectively. The voice announcer is connected to the proximity switch 3 through the wire 6, and when the rear-pressure trunk is closed, the sensing element 4 can be close to the sensing area of the proximity switch 3. When the rear-pressure trunk is opened, the sensing element 4 is away from the sensing area of the proximity switch 3. The switch state of the rear-pressure trunk can be known through the working state of the proximity switch 3, and the driver can be informed through the voice announcer in the cab.
[0035] Therefore, the voice alarm device of the present invention is equipped with a position detector between the box body 1 and the cover body 2 of the rear box of the rear pressure vehicle, which can detect the positional relationship between the box body 1 and the cover body 2. When the position detector detects that the cover body 2 is not closed, that is, the cover body 2 is separated from the box body 1, the voice announcer in the cab can broadcast a voice reminder to the driver in a loop to prevent the driver from starting the rear pressure vehicle without closing the cover body 2 and causing traffic accidents or environmental pollution. The device has a simple structure and is easy to install. It can be installed on the rear pressure vehicle as an independent auxiliary device. The warning effect is obvious and it is easy to use.
[0036] In the preferred solution, the proximity switch 3 can be installed on the outer surface of the box body 1 through a fixing frame 5. Those skilled in the art can understand that since the proximity switch 3 is usually a relatively small cylindrical structure, the contact surface between it and the box body 1 is limited. Direct installation is not only difficult to ensure the connection strength, but also easy to damage the proximity switch 3. Therefore, a fixing frame 5 can be set on the box body 1, and the proximity switch 3 can be installed on the fixing frame 5. In this way, the connection strength can be ensured and the position of the proximity switch 3 can be adjusted to align it with the sensing element 4.
[0037] Specifically, the shell of the proximity switch 3 is usually a cylindrical shape with threads, so the fixing frame 5 can be set as a fixedly connected base plate 7 and a clamping plate 8, wherein the base plate 7 and the box body 1 are fixedly connected, and a circular opening that matches the proximity switch 3 can be opened on the clamping plate 8, and the proximity switch 3 is inserted into the opening, and then two nuts are respectively screwed on both sides of the clamping plate 8 and clamped, so that the proximity switch 3 is fastened to the clamping plate 8.
[0038] Furthermore, the proximity switch 3 is a PNP normally closed proximity switch. The PNP normally closed proximity switch uses the principle of electromagnetic induction to switch the open and closed states of the circuit. However, unlike the normally open proximity switch, the circuit in the normally closed proximity switch is in a closed state when not triggered, and when a target object such as a sensing element 4 approaches the trigger, the circuit will be cut off, satisfying the detection logic of the rear trunk switch state, and it is easy to purchase, has low power consumption and high reliability.
[0039] In a preferred embodiment, the bottom plate 7 is an L-shaped plate. Figure 4 As shown, the L-shaped plate includes an inner side where the female corner is located, and an outer side where the male corner is located. The snap-in plate 8 can be set as a square plate, and the two sides of the square plate are fixedly connected to the two sides of the inner side of the L-shaped plate. This not only increases the contact area between the snap-in plate 8 and the bottom plate 7, making the connection between the two more firm and tight, but also the two empty sides of the L-shaped plate are convenient for screwing the nuts; at the same time, one or both sides of the outer side of the L-shaped plate can be fixedly connected to the box body 1.
[0040] Furthermore, both the bottom plate 7 and the clip plate 8 can be made of steel, which is not only high in strength, but also has good waterproof and corrosion resistance, and can better cope with sewage and corrosive substances; at the same time, the bottom plate 7 and the clip plate 8, as well as the bottom plate 7 and the box body 1 can be fixed by bolt connection, adhesive connection or welding. In this embodiment, welding is preferred. Welding not only has high connection strength, but also does not require drilling holes on the box body 1, and fixed connection is more convenient.
[0041] In the preferred solution, the sensing element 4 includes a metal facade. Those skilled in the art can understand that since the proximity switch 3 is installed on the fixing frame 5, especially the clamping plate 8, the proximity switch 3 will protrude from the surface of the box 1. In order to enable the sensing element 4 to be better close to the proximity switch 3, a metal facade can be provided.
[0042] Specifically, the installation position of the metal facade should be adapted to the sensing area of the proximity switch 3, so that when the cover body 2 and the box body 1 are in contact, the metal facade can trigger the proximity switch 3, and when the cover body 2 is separated from the box body 1, the metal facade can move away from the proximity switch 3 in time, thereby realizing the function of prompting the driver that the cover body 2 is not closed or not closed tightly.
[0043] In particular, when the cover body 2 is separated from the box body 1, no other metal parts on the rear pressure trunk should approach and trigger the proximity switch 3, so as to avoid the device being ineffective due to false triggering.
[0044] In the preferred solution, glass glue can be used to cover the connection between the proximity switch 3 and the wire 6. Those skilled in the art can understand that since the proximity switch 3 is installed on the outside of the box 1 and close to the opening, it is often exposed to corrosive substances such as sewage, and the connection between the wire 6 and the proximity switch 3 is prone to cracking due to multiple bending, which greatly affects the service life of the device; for this reason, glass glue can be used to cover the connection, which can not only strengthen the strength of the connection to prevent it from cracking or falling off, but also isolate it from corrosion by sewage.
[0045] In the preferred solution, the voice announcer has a built-in 65-decibel prompt voice, and the alarm effect of this decibel level is obvious but not too noisy.
[0046] In the preferred solution, the electric wire 6 is a three-core cable, which has good flexibility and durability, is corrosion-resistant and scale-resistant, and is suitable for rear pressure vehicles.

By setting up the voice alarm device, the safety hazard of the rear-pressing vehicle driver forgetting to close the trunk lid 2 after dumping garbage can be greatly reduced, and the situation of sewage polluting the street due to the lid 2 not being closed tightly can also be avoided.
[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
