Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments:
example 1
As shown in fig. 1 to 2, a cargo detecting system includes a housing 1, a touch panel 2, and a cargo detecting mechanism 3.
Wherein the goods detection mechanism 3 is located between the housing 1 and the touch plate 2.
As shown in fig. 3 and 4, the housing 1 has a "door" shape and includes a top plate 4, a left side plate 5, and a right side plate 6.
The left side plate 5 is connected below the left end of the top plate 4, and the right side plate 6 is connected below the right side of the top plate 4.
A vacant area 7 is provided between the left and right side plates 5 and 6 (i.e., the middle of the housing 1) for installing the touch panel 2.
Wherein, the left side plate 5 and the right side plate 6 are symmetrically arranged. The left side plate 5 is taken as an example for explanation:
as shown in fig. 3, the left side plate 5 includes a fixing plate 8, an intermediate connecting plate 9, and a mounting plate 10. The fixing plate 8, the intermediate connecting plate 9, and the mounting plate 10 may be formed by bending in this order, for example.
The fixing plate 8, the intermediate connecting plate 9 and the mounting plate 10 are connected in sequence and form a Z-shaped structure.
The fixing plate 8 is provided with a fixing hole 11, which is convenient for the installation of the cargo detection system.
The intermediate connecting plate 9 serves to connect the fixing plate 8 and the mounting plate 10 while allowing the housing 1 to have a certain thickness, and the width of the intermediate connecting plate 9 (i.e., the thickness of the housing 1) is sufficient to accommodate the corresponding components in the housing 1.
The mounting plate 10 is provided with a proximity switch bracket mounting hole 12 for mounting a proximity switch 18 described below.
The right side plate 6 has a structure symmetrical to the above-described left side plate 5, and will not be described in detail herein.
The touch panel 2 is disposed in the empty area 7, and the upper portion of the touch panel 2 is mounted to the top middle portion of the housing 1, i.e., the middle portion of the top plate 4, by a resilient hinge 13. Due to the presence of the resilient hinge 13, the touch panel 2 can move in the front-rear direction.
In addition, in order to limit the distance of the front and back movement of the touch plate 2, two sets of limit mechanisms 14 are designed.
One set of limiting mechanism 14 is located between the left side plate 5 of the housing 1 and the left side edge of the touch plate 2, and the other set of limiting mechanism 14 is located between the right side plate 6 of the housing 1 and the right side edge of the touch plate 2.
The range of the front and rear movement of the touch plate 2 can be limited by the two sets of limiting mechanisms 14.
As shown in fig. 2, one set of the limiting mechanisms 14 is taken as an example for explanation:
the limit mechanism 14 includes a limit bolt 15 and a limit plate 16.
Wherein, the limit bolt 15 is installed on the shell 1 and extends along the left and right direction (of the cargo detection system); the limit plate 16 is mounted on the touch panel 2 and extends in the front-rear direction (of the cargo detection system).
The limiting plate 16 is provided with a limiting hole 17, and the extending direction of the limiting hole 17 is the same as the extending direction of the limiting plate.
The free end of the stop bolt 15 extends into the stop hole 17.
The limiting hole 17 in this embodiment is preferably a strip-shaped hole or an arc-shaped hole.
When the touch pad 2 moves back and forth, the movement range of the touch pad 2 is limited due to the presence of the limit mechanism 14.
Of course, only one set of the limiting mechanism 14 may be provided, for example, only the limiting mechanism at the left side plate 5 or the right side plate 6 is remained.
Of course, two sets of limiting mechanisms can be arranged at the position of the left side plate 5 and arranged up and down, and only one set of limiting mechanism is arranged at the position of the right side plate 6. In addition, two sets of limiting mechanisms can be arranged at each side plate and are arranged up and down.
There are two sets of the cargo detection mechanisms 3, as shown in fig. 2.
One set is located between the left side plate 5 of the housing 1 (i.e., the left side portion of the housing) and the left side edge portion of the touch plate 2.
The other set is located between the right side plate 6 of the housing 1 (i.e. the right side portion of the housing) and the right side edge portion of the touch plate 2.
One set of the cargo detection mechanism 3 is taken as an example for explanation:
the cargo detection mechanism 3 is a non-contact sensor including a proximity switch 18 and a metal detector 19.
Wherein the proximity switch 18 is mounted to the housing 1 by a proximity switch bracket 20.
Preferably, the proximity switch bracket 20 is L-shaped, as shown in fig. 2, the proximity switch bracket 20 is mounted to the proximity switch bracket mounting hole 12 by bolts, and the proximity switch 18 is mounted to the proximity switch bracket 20 by bolts.
The metal detection body 19 is attached to the touch panel 2, and when the touch panel 2 moves forward and backward, the metal detection body 19 moves forward and backward along the touch panel 2, and the sensing area of the proximity switch 18 is located on the movement path of the metal detection body 19.
When goods press the touch panel 2, the touch panel 2 drives the metal detection body 19 to move backwards, and after the metal detection body 19 moves for a certain distance, the metal detection body 19 enters the detection range of the proximity switch 18, so that non-contact detection is realized.
The non-contact detection mode is favorable for prolonging the service life of the cargo detection system in the embodiment.
The proximity switch 18 of the same cargo detection mechanism 3 is located on the same side as the metal detection body 19, and for example, the proximity switch 18 shown in fig. 2 is located on the left side plate 5 of the housing 1, and the metal detection body 19 is located on the left side edge portion of the touch plate 2.
Of course, the cargo detection mechanisms 3 are not limited to the above two sets, and only one set of cargo detection mechanism 3 may be provided. For example, only the cargo detection mechanism at the left side panel 5, or only the cargo detection mechanism at the right side panel 6.
In addition, three, four or even more load detection mechanisms may be provided, and will not be discussed in detail herein.
Example 2
This embodiment 2 has mentioned a fork truck, and this fork truck includes lifting the portal, installs fork and goods detecting system on lifting the portal, and wherein, goods detecting system adopts the goods detecting system in above-mentioned embodiment 1.
The goods detecting system is arranged at the root of the fork, so that whether the tray is in place or not can be accurately detected conveniently.
Specifically, the shell 1 is mounted at the root of the fork through the fixing holes 11 on the left and right side plates in a matching manner.
Compared with the existing contact detection scheme, the occupied volume of the cargo detection system in the embodiment is significantly reduced, and thus the thickness of the housing 1 (i.e., the width of the intermediate connection plate 9 in the front-rear direction) is significantly reduced.
When the tray moves to the fork, the cargo detection system is located at the root of the fork and has small volume, so that the inner side of the tray is close to the root of the fork as much as possible, the contact area between the fork and the tray is increased, and the stability and the reliability are further enhanced.
In addition, the proximity switch 18 in this embodiment is no longer in direct contact with the tray, and thus the service life is increased.
It should be noted that the cargo detection system in this embodiment is not limited to be applied to the forklift, and may also be applied to other vehicles or places where it is necessary to detect whether the cargo is in place, and details are not described here.
Of course, the above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiment, and it should be noted that any equivalent substitution, obvious modification made by those skilled in the art under the teaching of the present specification fall within the essential scope of the present specification, and the protection of the present invention should be protected.
