The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, a truck in accordance with a preferred embodiment of the present invention includes a compartment, a hood, and a locking structure 100.

The carriage is used for bearing goods. Typically, the cabin has a receiving slot. The accommodating groove is used for accommodating goods.

The vehicle cover covers the notch of the accommodating groove and is used for sealing the accommodating groove, so that external water vapor, sunlight, dust and the like can be prevented from entering the accommodating groove to damage goods. Edges of opposite sides of the surface of the vehicle cover facing the accommodating groove are provided with edge grooves, and the locking structure 100 is arranged in the edge grooves. Typically, the hood is made of aluminum honeycomb panels. Furthermore, the hood may be an integrated hood or a folding hood.

The locking structure 100 is used to lock the hood to the compartment, so that the truck is prevented from falling off the compartment during operation. The side wall of the accommodating groove opposite to the truck head is provided with a tail door, and the tail door can be detached from the accommodating groove. Specifically, when the vehicle cover is installed, the tail gate is detached first, the vehicle cover is arranged at the notch, the locking structure 100 locks the vehicle cover, and finally the tail gate is installed. If the vehicle cover is to be detached from the carriage, the tail gate is detached first, and then the locking structure 100 is separated from the carriage, so that the vehicle cover can be detached.

Referring to fig. 2 and 3, a locking structure 100 according to a preferred embodiment of the present invention includes a body 110, a shifting member 120, an operating lever 130 and a locking member 140.

The body 110 serves as a support and a fixing. The accommodating groove 112 is provided with an opening 114 at one side. Generally, the body 110 may be made of an aluminum alloy, a steel plate, or other high molecular materials. Specifically in the present embodiment, the body 110 is made of an aluminum alloy. The aluminum alloy has high mechanical strength, and can prevent the body 110 from being deformed and broken during installation and operation. Moreover, the aluminum alloy also has a certain ductility, thereby facilitating the clamping of the locking structure 100 in the side groove. In the locking structure 100, the surface of the body 110 facing away from the accommodating groove 112 is disposed towards the bottom of the side groove.

In this embodiment, the locking structure 100 further includes two fixing blocks 170. Two fixing blocks 170 are detachably installed at both ends of the body 110 to close the receiving groove 112.

Limiting grooves (not shown) are respectively arranged at positions of the two fixing blocks 170 opposite to the two ends of the body 110, and the two ends of the body 110 are respectively clamped in the limiting grooves of the two fixing blocks 170 so as to seal the two ends of the accommodating groove 112. Because the vehicle cover is a honeycomb panel, a plurality of compact honeycomb structures are formed in the vehicle cover, and the two ends of the opened side groove are possibly regular in shape and also possibly irregular in shape. If the shapes of the two ends of the side groove are regular, the fixing blocks 170 can be installed at the two ends of the body 110, and the body 110 is clamped in the side groove, so as to realize the installation of the locking structure 100. If the shapes of the two ends of the side groove are irregular, the fixing block 170 can be detached from the body 110, and then the two ends of the body 110 are clamped and embedded in the honeycomb structure to fix the locking structure 100. And, the fixing blocks 170 are disposed at two ends of the body 110 to form the closed accommodating groove 112, which can also resist the elements of the locking structure 100, so as to prevent the elements of the locking structure 100 from colliding with the honeycomb structure of the vehicle cover during movement, thereby shortening the service life of the vehicle cover.

The shift member 120 is fixed in the receiving groove 112. Typically, the shift member 120 may be made of aluminum alloy, plastic steel or other polymer materials. In particular, in the present embodiment, the shift member 120 is made of nylon 6 (PA 6 for short) added with fifteen percent glass fiber. Therefore, the gear shift member 120 has better mechanical strength and dimensional stability, and can prevent the reliability of the locking structure 100 from being reduced due to deformation during the fixing process of the gear shift member in the receiving groove 112.

Specifically, the shift member 120 may be rectangular, circular, polygonal, or other shapes, and in this embodiment, the shift member 120 is rectangular. Generally, in order to reduce production costs, the body 110 is provided in a rectangular shape. Therefore, the rectangular gear shifting member 120 is matched with the rectangular body 110 in shape, so that the gear shifting member 120 is conveniently clamped in the accommodating groove 112 to achieve fixation. In addition, in order to enhance the fixing effect of the shift member 120, screws 180 are further disposed at two ends of the shift member 120, and the screws 180 can stably fix the shift member 120 in the receiving groove 112.

It should be noted that in other embodiments, the material, shape and fixing manner of the shift member 120 are not limited to the above, and may be set as required.

The surface of the shift member 120 facing the bottom of the receiving groove 112 is formed with a plurality of shift grooves 122. The plurality of shift grooves 122 are spaced apart along the length direction of the body 110. Different shift slots 122 correspond to different car sizes. The surface of the gear shifting member 120 facing away from the bottom of the accommodating groove 112 is provided with a through groove 123 communicating with the plurality of gear shifting grooves 122.

Referring to fig. 4 and 5, a shift portion 133 is formed at one end of the lever 130. The shift portion 133 is rotatably accommodated in any one of the shift grooves 122. The operation rod 130 is disposed through the through groove 123 and is slidable along the through groove 123. The operating lever 130 slides along the through slot 123 to drive the shift portion 133 to switch between the plurality of shift slots 122.

Therefore, when the size of the car changes, the operating lever 130 can drive the shifting portion 133 to slide along the through slot 123, so that the shifting portion 133 can switch positions among the plurality of shifting slots 122, and thus the locking range of the locking structure 100 can be adjusted to match cars with different sizes.

In this embodiment, the surface of the shift member 120 facing the bottom of the accommodating groove 112 is recessed inward in a direction facing away from the body 110 to form a recess 121. A plurality of shift slots 122 are disposed within recess 121.

The concave part 121 and the bottom of the 112 of the accommodating groove are jointly surrounded to form a gear shifting cavity. When shifting gears, the operating rod 130 slides along the extending direction of the through groove 123, so as to drive the gear shifting part 133 to move in the gear shifting cavity. When moving to the shift slot 122 in place, the operator operates the shift portion 133 and accommodates the shift portion 133 within the shift slot 122, thereby effecting shifting. Through setting up concave part 121 to set up a plurality of gear shifting grooves 122 in concave part 121, can provide sufficient removal space for gear shifting portion 133 when shifting, thereby be convenient for reduce the resistance in the gear shifting process, make gear shifting portion convenient operation, gear shifting efficiency obtain improving.

It should be noted that, in other embodiments, the rectangular gear shift member 120 may also be an elastic member, and the gear shift groove 122 is disposed on a surface of the gear shift member 120. When the shift portion 133 is switched between the plurality of shift grooves 122, the surface of the shift member 120 is pressed to form a concave structure of the surface. The two shift slots 122 requiring shifting are communicated through a concave structure, and the shifting member 120 moves in the concave structure, thereby moving from the previous shift slot 122 to the next shift slot 122. After the shift is completed, the deformation of the shift member 120 is restored.

In the locking structure 100, the inner wall profile of the gear shifting groove 122 may be spherical, triangular cone, cylindrical or other shapes, so long as the outer edge profile of the gear shifting portion 133 is matched with the inner wall profile, so that the gear shifting portion 133 is rotatably accommodated in any one of the gear shifting grooves 122. In this embodiment, the inner walls of the plurality of gear shift grooves 122 have a smooth arc surface structure and extend in a direction perpendicular to the body 110. The shift portion 133 has a cylindrical structure. The extending direction of the through groove 123 is parallel to the extending direction of the body 110, and each of the gear shifting grooves 122 and the through groove 123 are disposed axisymmetrically with respect to the axis of the body 110.

The gear shifting portion 133 with the cylindrical structure and the gear shifting groove 122 with the circular arc surface structure have smaller resistance during gear shifting, so that the operation is simple, and the labor is wasted. Meanwhile, the extrusion effect between the cylindrical structure and the arc surface structure is also small, so that mechanical damage to the shifting piece 120 caused by the shifting part 133 during shifting can be avoided, and the service life of the locking structure 100 can be prolonged conveniently. In other embodiments, the shapes of the shift portion 133 and the shift groove 122 are not limited to the above, and it is only necessary to ensure that the shift portion 133 can switch positions between the shift grooves 122.

Further, the extending direction of the shift groove 122 is set to be perpendicular to the direction of the body 110, and the extending direction of the through groove 123 is parallel to the extending direction of the body 110, so that the sliding path of the shift portion 133 is made parallel to the extending direction of the body 110. Therefore, the shift portion 133 has less resistance to the inner wall of the through groove 123 during shifting and has the shortest shift distance, thereby facilitating rapid shifting. In addition, the gear shifting grooves 122 and the through grooves 123 are axisymmetrically distributed about the axis of the body 110, so that the extrusion force of the gear shifting part 133 to the gear shifting piece 120 in the gear shifting process can be uniformly distributed on the body 110, and the deformation and even fracture of the body 110 due to the excessive concentration of stress can be prevented.

In addition, the shift portion 133 may be integrally formed with the lever 130 or may be formed separately from the lever 130. Specifically, in the present embodiment, an internal thread structure is provided in the middle of the gear shifting portion 133, and an external thread structure is provided at one end of the operating lever 130, and the internal thread structure is screwed with the external thread structure, so that the gear shifting portion 133 is firmly mounted on the operating lever 130.

The shift portion 133 is detachably mounted to the operating lever 130 by providing an internal thread structure and an external thread structure. When the shift portion 133 or the operating lever 130 is damaged, the shift portion 133 and the operating lever 130 can be removed and replaced, so that the shift portion 133 and the operating lever 130 have higher utilization rate. Meanwhile, the operating lever 130 is connected with the gear shifting portion 133 by adopting a threaded structure, and the bottom wall of the gear shifting groove 122 can be prevented from being scratched by using a fastener. In order to achieve a stable sliding effect, an internal thread structure should be provided in the middle of the shift portion 133.

Further, in the present embodiment, one side edge of each shift groove 122 is protruded to form a circular arc protrusion 125, and the other side edge is a smooth circular arc curved surface 126.

The arcuate projection 125 has a resisting function for the shift portion 133. When the gear shifting portion 133 is shifted, if the gear shifting portion 133 moves in the gear shifting slot 122 and slides out of the gear shifting slot 122, the arc protrusion 125 can limit the gear shifting portion 133 in the gear shifting slot 122 to be shifted. In addition, through setting up circular arc convex part 125 and circular arc curved surface 126, still can prevent that gear shifting portion 133 from producing friction with the surface of shifting piece 120 in the in-process that switches between a plurality of gear shifting grooves 122 to avoid shifting piece 120 and gear shifting portion 133 to produce mechanical damage, be convenient for prolong locking structure 100's life. In addition, in the present embodiment, the arc protrusion 125 and the arc curved surface 126 each extend in a direction perpendicular to the body 110.

It should be noted that, in other embodiments, both side edges of any one of the shift slots 122 may be configured as arc protrusions 125, arc curved surfaces 126, or other configurations.

The locking member 140 is fixed to the operating lever 130 and is located between both ends of the operating lever 130. Generally, the locking member 140 is a relatively concentrated stress element in the locking structure 100, and therefore, the locking member 140 needs to be made of an alloy, plastic steel or other polymer material with relatively high mechanical strength. Specifically, in the present embodiment, the locking member 140 is made of nylon 6 (PA 6 for short) added with fifteen percent glass fiber. Therefore, the locking member 140 has better mechanical strength and dimensional stability, and can prevent the locking member 140 from deforming in the process of locking the vehicle cover to influence the reliability.

Wherein the operating lever 130 operatively rotates the shift portion 133 to switch the locking member 140 between the locked state and the open state.

Specifically, the edges of the notch of the accommodating groove are formed with folds extending in a direction toward the bottom of the accommodating groove. When the locking member 140 is in the locking state, the locking member 140 abuts against the flange, and the vehicle cover is locked on the vehicle compartment. When the locking member 140 is in the open state, the locking member 140 is separated from the flange, so that the vehicle cover can be detached from the vehicle compartment, and cargo can be conveniently loaded and unloaded.

Therefore, in the truck and the locking structure 100 thereof, the operating rod 130 slidably passes through the through slot 123, and since the plurality of shift slots 122 are disposed at intervals along the length direction of the body 110, when the size of the compartment is changed, the operating rod 130 can drive the shift portion 133 to slide along the through slot 123, so that the shift portion 133 performs position switching between the plurality of shift slots 122, and thus, adjustment of the locking range of the locking structure 100 can be achieved to match with compartments of different sizes. And the operating lever 130 operatively rotates the shift portion 133 to switch the locking member 140 between the locked state and the unlocked state. When the locking member 140 is in the locked state, the locking structure 100 locks the hood to the cabin; when the locker 140 is in the opened state, the hood is detachable from the vehicle compartment. Therefore, compared with the conventional sliding locking structure 100, the locking structure 100 provided by the invention can realize gear conversion without disassembling the gear shifting member 120 and the operating lever 130 while satisfying the locking function, so as to be suitable for carriages with different sizes, thereby having higher gear shifting efficiency.

In this embodiment, the through groove 123 is a T-shaped through groove. The T-shaped through groove includes a communicating portion 1231 and an installation portion 1232. The communicating portion 1231 communicates with the plurality of shift grooves 122. The mounting portion 1232 is disposed at one end of the communicating portion 1231 and communicates with the communicating portion 1231, and an outer contour of the mounting portion 1232 matches an outer contour of the shift portion 133.

The shift portion 133 can extend from the mounting portion 1232 into the shift slot 122 to effect mounting of the operating lever 130. Therefore, by providing the T-shaped through groove, the operating lever 130 and the lock member 140 can be detachably mounted to the shift member 120. Therefore, when the operating lever 130 or the locker 140 is deformed or damaged, the shift portion 133 can be detached from the mounting portion 1232 and the operating lever 130 or the locker 140 can be replaced without the entire locking structure 100 being detached. In addition, in the present embodiment, the communication part 1231 is parallel to the extending direction of the body 110, and the extending direction of the mounting part 1232 is perpendicular to the extending direction of the body 110.

Further, in this embodiment, a clamping groove 124 is further disposed on a surface of the shifting member 120 facing away from the shifting groove 122. The locking groove 124 communicates with the mounting portion 1232, and the locking groove 124 and the communicating portion 1231 are located on opposite sides of the mounting portion 1232.

Therefore, when the cover is to be removed, in order to prevent the operation lever 130 from being mechanically damaged by collision with the surface of the cover during the removal process, the operation lever 130 may be rotated, and the operation lever 130 may be locked in the locking groove 124, so that the operation lever 130 may be fixed in the receiving groove 112. Therefore, the locking structure 100 can be accommodated when not in use by providing the clamping groove 124, so that the volume of the locking structure 100 can be reduced, and the miniaturization of the locking structure 100 is facilitated. At the same time, the provision of the clamping groove 124 can avoid the use of excessive fasteners, thereby increasing the production cost.

Further, in order to prevent the operation rod 130 from falling out of the clamping groove 124, elastic protrusions 1241 may be disposed on two opposite side walls of the clamping groove 124, and the extending direction of the elastic protrusions 1241 is perpendicular to the extending direction of the body 110, so as to play a role in resisting when the operation rod 130 slides out of the clamping groove 124, so as to prevent the operation rod 130 from falling out of the clamping groove 124.

In the present embodiment, the locking member 140 includes a lock body 141 and a locking portion 142 bent in a direction toward the shift portion 133 with respect to the lock body 141. A screw hole is formed in a position of the lock body 141 opposite to the operation lever 130, and the operation lever 130 is screwed into the screw hole.

The lock body 141 is used to fix the entire locker 140 such that the locker 140 can be rotated in synchronization with the operating lever 130. The locking member 140 is rotated to make the end of the locking portion 142 abut against or separate from the folded edge. Therefore, by providing the lock body 141 and the locking portion 142, the locking manner of the locking structure 100 and the hood is simple and easy to operate, so as to shorten the time for installing and detaching the hood, thereby improving the working efficiency of the truck.

In particular, in the present embodiment, the extending direction of the operating lever 130 coincides with the central axis direction of the locking member 140. Accordingly, the locker 140 forms an axisymmetric structure with respect to the operating lever 130. In this way, stress can be uniformly distributed on the locking member 140 in the process of rotating the operating rod 130, so that the locking member 140 can be stably fixed on the operating rod 130.

In this embodiment, the locking structure 100 further includes a handle 150 and a cross bar 160. A groove 151 is formed at a position of the handle 150 opposite to the operating rod 130, and limiting holes are formed at positions of two inner walls of the groove 151 opposite to the operating end 132. The cross bar 160 is provided with a fixing hole 161 at a position opposite to the operation lever 130. The operation end 132 is accommodated in the groove 151 and penetrates through the fixing hole 161, and the cross bar 160 penetrates through the limiting holes 152 on the two inner walls of the groove 151.

When the locking structure 100 is operated, an operator rotates the handle 150, so that the operating lever 130 rotates relative to the shift member 120, and the locking member 140 abuts against or separates from the folded edge. By providing the handle 150, the operator can apply a force to the operation lever 130 to trigger the operation lever 130 to move, thereby having a better sense of use. Meanwhile, by arranging the cross bar 160, the operation rod 130 can be prevented from moving relative to the handle 150 in the rotating process, so that the operation rod 130 can be stably fixed on the handle 150, and the normal use of the locking structure 100 can be maintained.

In this embodiment, the surface of the locking member 140 facing away from the body 110 is provided with a stepped groove 144. One end of the handle 150 is provided with a step portion 153 matching the shape of the step groove 144, and the step portion 153 is held in the step groove 144. The protrusions 154 are formed on opposite sides of the stepped groove 144, and the distal ends of the protrusions 154 are abutted against the handle 150.

By providing the stepped groove 144, the stepped portion 153, and the boss 154, the locker 140 is stably fixed to the locker 140 while being fixed to the operating lever 130. Therefore, during the rotation of the handle 150, the locking member 140 can be driven to rotate, so that the rotation of the locking member 140 can be started more flexibly. If any one of the lever 130 or the handle 150 is loosely coupled to the locking member 140, the other member can rotate the locking member 140, thereby facilitating maintenance of the normal operation of the locking structure 100.

Further, in the present embodiment, the stepped groove 144 and the stepped portion 153 are symmetrically disposed with respect to the operation lever 130.

Therefore, in the process that the handle 150 drives the locking member 140 to rotate, the stress can be uniformly distributed on the locking member 140, so that the locking member 140 and the handle 150 are prevented from slipping to influence the work of the locking member 140.

The truck and the locking structure 100 thereof, the operating rod 130 is slidably disposed in the through groove 123, and since the plurality of shifting grooves 122 are disposed at intervals along the length direction of the body 110, when the size of the compartment is changed, the operating rod 130 can drive the shifting portion 133 to slide along the through groove 123, so that the shifting portion 133 can switch positions among the plurality of shifting grooves 122, and thus, the locking range of the locking structure 100 can be adjusted to match with compartments of different sizes. And the operating lever 130 operatively rotates the shift portion 133 to switch the locking member 140 between the locked state and the unlocked state. When the locking member 140 is in the locked state, the locking structure 100 locks the hood to the cabin; when the locker 140 is in the opened state, the hood is detachable from the vehicle compartment. Therefore, compared with the conventional sliding locking structure 100, the locking structure 100 provided by the invention can realize gear conversion without disassembling the gear shifting member 120 and the operating lever 130 while satisfying the locking function, so as to be suitable for carriages with different sizes, thereby having higher gear shifting efficiency.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
