Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. indicate an orientation or a positional relationship based on that shown in the drawings or that the product of the present invention is used as it is, this is only for convenience of description and simplification of the description, and it does not indicate or imply that the device or the element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

Furthermore, the appearances of the terms "first," "second," and the like, if any, are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.

In the prior art, the supporting devices used include two main categories: one type is a telescopic rod, the telescopic rod consists of a plurality of sections of rods, and when the top cover is opened, the telescopic rod is locked by a locking structure arranged between adjacent rod pieces, so that the supporting device can stably support the top cover; the other type is a folding rod which is composed of two rod pieces capable of rotating relatively, the folding rod is straightened and locked through a locking structure 132 between the two rod pieces, so that the supporting device realizes stable support for the top cover. The locking structure of the supporting device is arranged between the adjacent rod pieces in the supporting device, and in order to improve the supporting capacity and reduce the occupied space of the supporting device as much as possible, after the top cover is opened, the whole supporting device can be closer to the hinge position of the top cover, but an operator is usually positioned at the opening side of the top cover, so that the locking structure in the supporting device is far away from the operator after the top cover is opened. When the locking of the locking structure needs to be released to close the roof cover subsequently, an operator needs to stretch hands or feet with great effort to release the locking structure, and particularly when the operator stands on a vehicle body, the operator is easy to have unstable gravity center and have accidents such as falling injury.

To solve the above problem, referring to fig. 1 and 2, the present embodiment provides a construction machine including an engine compartment. The engine compartment includes a roof cover 200, a nacelle body, and a support apparatus 100. The roof cover 200 is pivotally connected to the cabin, and in particular, the roof cover 200 is hinged to the cabin by a hinge. The support 110 is fixed to the cabin, and the support device 100 is used for supporting the engine top cover 200 to maintain the open state of the engine top cover 200.

The supporting device 100 includes a bracket 110, a stopper rod 130, and a supporting rod 150. The bracket 110 is used for being fixed to the engine compartment, the bracket 110 has a first side 111 and a second side 112 opposite to each other, and the first side 111 and the second side 112 are spaced apart and opposite to each other along a predetermined direction. In the present embodiment, the preset direction is a front-back direction, the first side 111 is a front side, the second side 112 is a back side, and the top cover 200 can be opened from the first side 111, that is, the operator opens the top cover 200 from the front side. The bracket 110 is provided with a first pin 113 and a second pin 114 at intervals. In this embodiment, the first pin 113 and the second pin 114 are disposed at an interval along a predetermined direction, and both the first pin 113 and the second pin 114 extend along a horizontal direction and are perpendicular to the vertical surface of the bracket 110.

The limiting rod 130 is slidably connected to the bracket 110, one end of the supporting rod 150 is rotatably connected to the limiting rod 130, and the other end is rotatably connected to the top cover 200. One end of the limiting rod 130 close to the first side 111 is provided with a locking structure 132, and the locking structure 132 is used for locking the position of the limiting rod 130 relative to the bracket 110, so that the supporting rod 150 can support the top cover 200.

Wherein, the spacing is provided with first spout 131 and second spout 133 in gag lever post 130 interval, and the length of first spout 131 and second spout 133 is equal. The first sliding slot 131 is located on a side of the second sliding slot 133 close to the first side 111, i.e. the first sliding slot 131 is in front and the second sliding slot 133 is in rear. The first pin 113 is slidably engaged with the first sliding groove 131, and the second pin 114 is slidably engaged with the second sliding groove 133, so that the limiting rod 130 can have a sliding stroke with a certain length relative to the bracket 110. In this embodiment, the first and second

sliding grooves

131 and 133 extend in a predetermined direction, respectively, so that the stopper 130 can move only in the predetermined direction relative to the bracket 110. In addition, in the present embodiment, the length direction of the limiting rod 130 is parallel to the predetermined direction, so that the limiting rod 130 can be as close to the opening side as possible when sliding, so that an operator can conveniently touch the limiting rod 130 to operate the locking structure 132 disposed thereon. In other embodiments, the length of the second chute 133 may be greater than that of the first chute 131.

In this embodiment, the limiting rod 130 slides along the predetermined direction, i.e. the front-back direction, it can be understood that in other embodiments, the limiting rod 130 may not slide along the predetermined direction, and at this time, the first sliding groove 131 and the second sliding groove 133 may not extend along the predetermined direction, but form an included angle with the predetermined direction. Since the stop bar 130 is essentially only required to be relatively close to or far from the first side 111 for easy access by the operator, and the sliding direction thereof is not necessarily required to be the front-back direction.

Referring to fig. 3, 4 and 5, the locking structure 132 includes a locking groove 134. The first end 136 of the locking groove 134 is communicated with the end of the first sliding slot 131 close to the first side 111, and the second end 137 of the locking groove 134 far away from the first end 136 is located below the first sliding slot 131. When the first pin 113 is inserted into the locking groove 134, the locking groove 134 can catch the first pin 113.

Specifically, the locking groove 134 includes a curved hook groove 135, the hook groove 135 having a first end 136 and a second end 137. First end 136 is in communication with an end of first runner 131 proximate first side 111, second end 137 is positioned below first runner 131, and hook slot 135 is convex toward first side 111. The hook groove 135 and the first runner 131 together constitute a J-shaped groove. The minimum distance between the projection of second end 137 on first sliding chute 131 and first end 136 is greater than the diameter of first pin 113, so that first pin 113 cannot easily disengage after sliding into second end 137 of hook groove 135, and the minimum distance between the projection of second end 137 on first sliding chute 131 and first end 136 is smaller than the length of second sliding chute 133, that is, smaller than the length of first sliding chute 131, so that second end 137 can be located below first sliding chute 131. Since the minimum distance between the projection of the second end 137 of the hook groove 135 on the first sliding groove 131 and the first end 136 is smaller than the length of the second sliding groove 133, when the first pin 113 slides from the first sliding groove 131 into the hook groove 135, if the limiting rod 130 has a tendency to move forward, the inner wall of the hook groove 135 at the second end 137 stops the first pin 113, and prevents the limiting rod 130 from moving forward. Thus, the hook groove 135 can limit the first pin 113, and further limit the limit rod 130.

In this embodiment, the locking groove 134 and the first sliding groove 131 are J-shaped, and in other embodiments, the locking groove 134 may also be a straight groove. At this time, an included angle is formed between the locking groove 134 and the first sliding groove 131, and a distance between a projection of the second end 137 of the locking groove 134 on the first sliding groove 131 and the first end 136 is greater than a diameter of the first pin 113 and smaller than a length of the second sliding groove 133, so that the first pin 113 can be limited even if the locking groove 134 is straight.

The support bar 150 is rotatably connected to the top cover 200. In this embodiment, one side of the top cover 200 close to the second side 112 is hinged to the cabin, and two ends of the supporting rod 150 are respectively hinged to the limiting rod 130 and the top cover 200. When the hood 200 is opened or closed, the support bar 150 can rotate relative to the hood 200 and the stop bar 130. The supporting rod 150 is rotatably connected to one end of the limiting rod 130 near the second side 112, so that no extra part exists in the limiting rod 130, and when the top cover 200 is closed and the supporting rod 150 and the limiting rod 130 are folded with each other, the limiting rod 130 does not occupy too much space, and thus other parts are prevented from being obstructed.

In addition, in this embodiment, the support bar 150 and the limiting bar 130 are set to have suitable lengths, and when the top cover 200 is closed, the length direction of the support bar 150 and the length direction of the limiting bar 130 are respectively parallel to the preset direction, and the included angle between the support bar 150 and the limiting bar 130 is 180 °. Therefore, when the top cover 200 is closed, the occupied spaces of the support rod 150 and the limiting rod 130 can be effectively reduced, and interference or interference on other parts can be avoided.

In this embodiment, the support 110 is provided with a pin, and the limiting rod 130 is provided with a sliding slot, in other embodiments, the limiting rod 130 may be provided with a pin, and the support 110 is provided with a sliding slot, which may also meet the sliding requirement of the limiting rod 130. At this time, the bracket 110 is provided with a first sliding groove 131, a second sliding groove 133 and a locking groove 134, and the locking groove 134 is communicated with the first sliding groove 131 and is located above the first sliding groove 131. The limiting rod 130 is provided with a first pin shaft 113 and a second pin shaft 114, when one end of the limiting rod 130 close to the first side 111 is tilted upwards, the first pin shaft 113 can enter the locking groove 134 from the first sliding groove 131, and the locking groove 134 can be additionally provided with a limiting part for limiting the first pin shaft 113, so that the limiting rod 130 is locked.

The working principle and working process of the supporting device 100 are as follows:

when the top cover 200 is opened, an operator opens the top cover 200 from the first side 111, i.e., the front side, the top cover 200 rotates relative to the bracket 110, and the supporting rod 150 rotates along with the top cover 200 and drives the limiting rod 130 to slide toward the second side 112, i.e., the rear side. The second runner 133 and the first runner 131 are equal in length, and when the second pin 114 abuts against the inner wall of the second runner 133 close to the first side 111, the first pin 113 abuts against the inner wall of the first runner 131 close to the first side 111. At this moment, the operator puts down the hood 200 so that the hood 200 pushes down the end of the limiting rod 130 far away from the first side 111 through the support rod 150, thereby making the end of the limiting rod 130 near the first side 111 upwarp, and when the end of the limiting rod 130 near the first side 111 upwarps, the first pin shaft 113 can slide into the hook groove 135 because the first end 136 of the hook groove 135 is communicated with the end of the first sliding groove 131 near the front side. The hook groove 135 is integrally protruded and bent forward, and the first pin 113 slides into the hook groove 135 and then slides to the second end 137 of the hook groove 135 along the extending direction of the hook groove 135. Due to the gravity, the top cover 200 generates a forward component force on the limit rod 130 through the support rod 150, so that the limit rod 130 always tends to slide forward relative to the first pin 113. Since the minimum distance between the projection of the second end 137 of the hook groove 135 on the first sliding groove 131 and the first end 136 is smaller than the length of the second sliding groove 133, the first pin 113 is stopped by the inner wall of the second end 137 of the hook groove 135 to prevent the limiting rod 130 from sliding forward. The minimum distance between the projection of the second end 137 of the hook groove 135 on the first sliding groove 131 and the first end 136 is greater than the diameter of the first pin 113, so that the first pin 113 cannot easily disengage from the hook groove 135, and the locking of the limit rod 130 is realized through the locking groove 134. After the position-limiting rod 130 is locked, the support rod 150 is relatively fixed under the pressure of the top cover 200, so that the top cover 200 is stably supported, and the opening state of the top cover 200 is maintained.

When closing the top cover 200, the operator may push and press the end of the limiting rod 130 close to the first side 111 to make the first pin 113 disengage from the hook groove 135 and slide into the first sliding groove 131, the limiting rod 130 may slide forward relative to the bracket 110, the supporting rod 150 rotates therewith, and the top cover 200 is pulled to rotate relative to the bracket 110, thereby achieving the closing. Because the locking groove 134 sets up in the one end that gag lever post 130 is close to first side 111, locking groove 134 sets up in the one end of being close to the side of opening promptly, and is nearer apart from operating personnel, makes things convenient for operating personnel to touch, and then makes things convenient for operating personnel to remove the locking, conveniently closes quick-witted top hood 200.

In summary, the supporting device 100 facilitates unlocking by an operator by disposing the locking structure 132 at an end of the limiting rod 130 close to the first side 111, thereby improving operation safety. Meanwhile, the supporting device 100 has a simple structure, is easy and convenient to operate and occupies a small space.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
