Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology, specifically relating to an adjustment device for a vehicle-mounted escalator. Background Technology

[0002] Freight trucks, also known as cargo trucks or lorries, are vehicles primarily used for transporting goods, and sometimes also refer to vehicles capable of towing other vehicles. They belong to the category of commercial vehicles. They are generally classified into heavy-duty and light-duty types based on their weight. The vast majority of freight trucks are powered by diesel engines, but some light-duty trucks use gasoline, LPG, or natural gas.

[0003] To facilitate the placement of goods on top, a vehicle-mounted ladder is installed between the truck bed and the cab. This ladder allows operators to climb to the top of the truck bed. To ensure the stability of the ladder, it is usually welded directly to the truck bed.

[0004] However, in order to meet the installation space requirements of the vehicle-mounted escalator, space needs to be reserved between the carriage and the front of the vehicle for the installation of the vehicle-mounted escalator, which results in a longer overall length of the vehicle frame and thus increases production costs. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an adjustment device for a vehicle-mounted escalator to solve the technical problem in the background art that, in order to meet the installation space requirements of the vehicle-mounted escalator, space needs to be reserved between the car body and the front of the vehicle for the installation of the vehicle-mounted escalator, which results in a longer overall length of the vehicle frame and thus increases production costs.

[0006] The present invention proposes an adjustment device for a vehicle-mounted escalator, the adjustment device being used to install the vehicle-mounted escalator on a vehicle car so that the position of the vehicle-mounted escalator relative to the vehicle car can be adjusted;

[0007] The adjustment device includes a support frame, on which at least one bending member is provided. The bending member is located in the middle of the support frame and divides the support frame into at least two supports. One of the two supports is used to connect to the carriage, and the other is separated from the carriage to form an adjustment space.

[0008] The vehicle-mounted escalator includes a first pole and a second pole that is bent and connected to the first pole. The first pole is used to pass through the adjustment space so that the second pole is located on the support frame.

[0009] Each of the two brackets is provided with at least one slot, which is used to engage the second rod. By engaging the second rod in either of the slots, the movement of the escalator relative to the vehicle car in at least one direction is restricted.

[0010] The support frame includes a first bracket and a second bracket, and the ends of the first bracket and the second bracket that are close to each other are connected by the bending member.

[0011] The first bracket is used to connect with the carriage, and the second bracket is provided with a gap between it and the carriage to form the adjustment space.

[0012] Furthermore, the first bracket and the second bracket are arranged opposite to each other;

[0013] The bending member includes a first connecting portion opposite to the first bracket or the second bracket, through which at least a portion of the second bracket extends beyond the end face of the first bracket, thereby forming a first gap between the second bracket and the first bracket for the first rod to move.

[0014] The second bracket is provided with a first slot opposite to the first gap. By extending the first rod into the first gap, the second rod is engaged in the first slot, so that the vehicle escalator and the side of the car are staggered.

[0015] Furthermore, the bending member also includes at least two second connecting portions, the two ends of which are respectively connected to the two ends of the first connecting portion. Through the second connecting portions, a second gap is provided between the first bracket and the second bracket to allow the first rod to move.

[0016] The first gap, the second gap, and the adjustment space are interconnected, and the first bracket is provided with a second slot. By passing the first rod through the second gap, the first rod is adjusted within the adjustment space so that the second rod is engaged in the second slot, so that the vehicle escalator is positioned opposite one side of the vehicle.

[0017] Furthermore, the ends of the first connecting portion and the second connecting portion that are close to each other are bent and connected together.

[0018] Furthermore, the first support includes a first support portion and a second support portion that is bently connected to the first support portion;

[0019] The second bracket includes a third support portion opposite to the first support portion and a fourth support portion opposite to the second support portion, wherein the third support portion and the fourth support portion are bent together.

[0020] The first gap is located between one side of the first support portion and one side of the third support portion, and the second gap is located between one end of the first support portion and one side of the fourth support portion.

[0021] Furthermore, the first connecting portion is disposed opposite to the first supporting portion or the third supporting portion, and the second connecting portion is disposed opposite to the second supporting portion or the fourth supporting portion.

[0022] Furthermore, the adjusting device also includes a plurality of connectors, at least two of which are respectively disposed on the first rod and the second rod;

[0023] The first slot has at least two slots, and the second slot has at least two slots. The size of the first slot and the second slot is larger than the size of the connector. By respectively engaging the two connectors in the first slot and the second slot, the movement of the escalator relative to the car is restricted in at least two directions.

[0024] Furthermore, the connector includes a first connector and a second connector, the first slot is used to engage the first connector, and the second slot is used to engage the second connector. By extending the first connector and the second connector into the first slot and the second slot respectively, the radial and axial movement of the escalator relative to the vehicle is restricted.

[0025] Furthermore, the first connector is fixedly connected to the first rod, and the second connector is fixedly connected to the second rod.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] In the vehicle-mounted escalator adjustment device provided by the present invention, the adjustment device includes a support frame and a bending member, and the support frame is divided into at least two brackets by the bending member. At least one slot is provided on each of the two brackets. The adjustment device is used to install the vehicle-mounted escalator onto the vehicle car, so that the position of the vehicle-mounted escalator relative to the vehicle car can be adjusted. That is, using the adjustment device, the vehicle-mounted escalator can be installed laterally between the vehicle car and the front of the vehicle during installation. Furthermore, the slot limits the second rod on the vehicle-mounted escalator, ensuring that the vehicle-mounted escalator is in a retracted state. When it is necessary to unfold the vehicle-mounted escalator for workers to climb, the device can be used to adjust its position. The adjustable space between the two supports allows the escalator to be rotated, changing it from a retracted to an extended state. Another slot restricts the second pole in another direction, allowing workers to climb. In other words, during installation, the escalator can be initially installed sideways between the carriage and the front of the vehicle. When it needs to be extended, the position can be changed by adjusting the space, transforming the sideways escalator into a forward-facing one. This significantly reduces the space required between the carriage and the front of the vehicle, thereby reducing the overall length of the frame and lowering costs. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] Please see Figures 1 to 7 The image shows an adjustment device for a vehicle-mounted escalator according to an embodiment of the present invention. The adjustment device 100 is used to install the vehicle-mounted escalator 200 on the vehicle 300 so that the position of the vehicle-mounted escalator 200 relative to the vehicle 300 can be adjusted. It should be noted that the vehicle-mounted escalator 200 can be a vehicle-mounted escalator 200 in the prior art, which can be composed of two first rods 210 and multiple second rods 220. The second rods 220 are disposed between the two first rods 210 and are bently connected to the first rods 210.

[0040] The adjustment device 100 includes a support frame 110, and at least one bending member 120 is provided on the support frame 110. The bending member 120 is located in the middle of the support frame 110 and the support frame 110 is divided into at least two supports by the bending member 120. One of the two supports is used to connect with the carriage 300, and the other is provided with a gap between it and the carriage 300 to form an adjustment space 140.

[0041] The first rod 210 is used to pass through the adjustment space 140 so that the second rod 220 is located above the support frame 110;

[0042] Each of the two brackets is provided with at least one slot 130, which is used to engage the second rod 220. By engaging the second rod 220 into either slot 130, the movement of the vehicle escalator 200 relative to the car 300 in at least one direction is restricted.

[0043] Specifically, in this embodiment, the support frame 110 can be composed of two supports, namely a first support 111 and a second support 112. The ends of the first support 111 and the second support 112 that are close to each other are connected by a bending member 120. The first support 111 is used to connect with the carriage 300, and a gap is provided between the second support 112 and the carriage 300 to form an adjustment space 140. It should be noted that the first support 111 and the second support 112 are arranged opposite to each other, and the bending member 120 includes a component opposite to the first support 111 or the second support 112. The first connecting portion 121 allows at least a portion of the second bracket 112 to extend beyond the end face of the first bracket 111, forming a first gap 123 between the second bracket 112 and the first bracket 111 for the first rod 210 to move. The second bracket 112 is provided with a first slot 131 opposite to the first gap 123. By extending the first rod 210 into the first gap 123, the second rod 220 is engaged in the first slot 131, so that the vehicle escalator 200 and the car 300 are staggered on one side.

[0044] It should be noted that the first slot 131 mentioned above is the first of the slots 130. For ease of understanding, the positions of the vehicle-mounted escalator 200 will be described using the first and second positions. The first position indicates that the vehicle-mounted escalator 200 is in its extended state, allowing workers to climb it; the second position indicates the retracted state of the vehicle-mounted escalator 200. Please refer to [link / reference needed]. Figures 6 to 7 As shown.

[0045] When the first pole 210 of the escalator 200 extends into the first gap 123, the second pole 220 is engaged in the first slot 131. The first slot 131 limits the second pole 220, and the first gap 123 limits the first pole 210, so that the escalator 200 is in the first position, which can be climbed by staff.

[0046] In order to store the vehicle-mounted escalator 200, in this embodiment, the bending member 120 further includes at least two second connecting parts 122. The two ends of the two second connecting parts 122 are respectively connected to the two ends of the first connecting part 121. Through the second connecting parts 122, a second gap 124 is provided between the first support 111 and the second support 112 for the first rod 210 to move.

[0047] The first gap 123, the second gap 124 and the adjustment space 140 are interconnected, and the first bracket 111 is provided with a second slot 132. By passing the first rod 210 through the second gap 124, the first rod 210 is adjusted within the adjustment space 140 so that the second rod 220 is engaged in the second slot 132, so that the vehicle escalator 200 and the carriage 300 are arranged opposite each other.

[0048] Specifically, the first bracket 111 includes a first support portion 1111 and a second support portion 1112 that is bently connected to the first support portion 1111;

[0049] The second support 112 includes a third support 1121 opposite to the first support 1111 and a fourth support 1122 opposite to the second support 1112, and the third support 1121 and the fourth support 1122 are bent together.

[0050] The first gap 123 is located between one side of the first support portion 1111 and one side of the third support portion 1121, and the second gap 124 is located between one end of the first support portion 1111 and one side of the fourth support portion 1122.

[0051] In some preferred embodiments, the ends of the first connecting portion 121 and the second connecting portion 122 that are close to each other are bent and connected, and the bending member 120 can be Z-shaped, and the first bracket 111 and the second bracket 112 can be L-shaped.

[0052] In other words, when the escalator 200 is in the first position, it needs to be stowed. When adjusting the position of the escalator 200, an upward force can be applied to it, causing the second rod 220 to disengage from the first slot 131 and allowing the first rod 210 to pass through the first gap 123 and the second gap 124 in sequence, so that the first rod 210 is within the adjustment space 140. At this time, the escalator 200 is turned so that the angle of the second rod 220 can be changed. At this time, the escalator 200 is positioned opposite one side of the carriage 300, that is, the escalator 200 enters laterally into the reserved space between the carriage 300 and the front of the carriage, and utilizes the adjustment space 140. 40, allowing the second rod 220 to be inserted into the adjustment space 140, and finally the second rod 220 to be engaged in the second slot 132, completing the storage of the vehicle escalator 200. In other words, when installing the vehicle escalator 200, it can be installed in the stored state first. When it is necessary to unfold the vehicle escalator 200, the angle of the vehicle escalator 200 can be changed by utilizing the cooperation between the first gap 123, the second gap 124 and the adjustment space 140, thereby enabling the lateral vehicle escalator 200 to be transformed into a forward-facing one. This greatly reduces the reserved space between the carriage 300 and the front of the vehicle, thereby reducing the overall length of the frame and lowering certain costs.

[0053] Furthermore, the adjusting device 100 also includes a plurality of plug-in members 150, at least two of which are respectively disposed on the first rod 210 and the second rod 220;

[0054] The first slot 131 has at least two slots, and the second slot 132 has at least two slots. The size of the first slot 131 and the second slot 132 is larger than the size of the connector 150. The two connectors 150 are respectively snapped into the first slot 131 and the second slot 132 to restrict the movement of the vehicle escalator 200 relative to the car 300 in at least two directions.

[0055] Specifically, there can be two connectors 150, which include a first connector 151 and a second connector 152. A first slot 131 is used to engage the first connector 151, and a second slot 132 is used to engage the second connector 152. When the first connector 151 and the second connector 152 are inserted into the first slot 131 and the second slot 132 respectively, the radial and axial movement of the escalator 200 relative to the car 300 is restricted.

[0056] In other words, to ensure the stability of the vehicle-mounted escalator 200 when it is unfolded or retracted, the first connector 151 and the second connector 152 are simultaneously inserted into the first slot 131 and the second slot 132, thereby increasing the limiting direction of the vehicle-mounted escalator 200. That is, the first slot 131 and the second slot 132 can restrict the radial and axial movement of the vehicle-mounted escalator 200, thereby ensuring that the overall state is relatively stable when the staff climbs the vehicle-mounted escalator 200, further ensuring the stability of the vehicle-mounted escalator 200 when it is retracted or unfolded.

[0057] The first connector 151 is fixedly connected to the first rod 210, and the second connector 152 is fixedly connected to the second rod 220. In some preferred embodiments, the fixed connection can be achieved by welding.

[0058] It should be noted that you should refer to [link / reference]. Figure 4 As shown, the first slot 131 on the third support portion 1121 and the second slot 132 on the first support portion 1111 can be on the same axis. That is to say, the second slot 132 on the first support portion 1111 can also engage the first connector 151.

[0059] In summary, the vehicle-mounted escalator adjustment device provided in one embodiment of the present invention has at least the following advantages compared with the existing installation methods for vehicle-mounted escalators:

[0060] In the vehicle-mounted escalator adjustment device provided by the present invention, the adjustment device 100 includes a support frame 110 and a bending member 120. The support frame 110 is divided into at least two supports by the bending member 120, and at least one slot 130 is provided on each of the two supports. The adjustment device 100 is used to install the vehicle-mounted escalator 200 on the vehicle car 300 so that the position of the vehicle-mounted escalator 200 relative to the vehicle car 300 can be adjusted. That is, by using the adjustment device 100, the vehicle-mounted escalator 200 can be installed laterally between the vehicle car 300 and the front of the vehicle during installation. The slot 130 is used to limit the second rod 220 on the vehicle-mounted escalator 200, which can ensure that the vehicle-mounted escalator 200 is in the retracted state. When it is necessary to unfold the vehicle-mounted escalator 200, it can be used for workers to climb. When climbing, the adjustable space 140 between the two supports allows the escalator 200 to be turned, changing it from a retracted state to an extended state. Another slot 130 limits the second pole 220 in another direction, allowing workers to climb. In other words, when installing the escalator 200, it can first be installed in a retracted state. When it needs to be extended, the first gap 123, the second gap 124, and the adjustable space 140 are used to change the angle of the escalator 200, thus changing it from a lateral position to a forward position. This significantly reduces the space required between the carriage 300 and the front of the vehicle, thereby reducing the overall length of the frame and lowering costs.
