[0039] As mentioned in the background technology: With the development of diversified functions of commercial vehicles, in order to meet the requirements of convenient cargo pickup, the traditional side sliding door structure can no longer meet the demand, and for this reason, a lift-up cargo pickup door structure is introduced.
[0040] In order to meet the appearance and functional requirements such as the gap and surface difference of the lift-up pickup door structure, a limiting structure is added.
[0041] However, the current limiting structure can only limit the vertical direction of the pickup door, but cannot limit the horizontal direction of the pickup door, which affects the limiting effect of the pickup door.
[0042] In order to solve the technical problems raised above, the present application provides a pickup door limiting structure and a vehicle. The limiting structure of the pickup door is provided by setting a limiting body, and the limiting body has a first limiting surface and a second limiting surface. The first limiting surface is configured to abut against the side surface of the pickup door to limit the position of the pickup door in the horizontal direction; the second limiting surface is configured to abut against the bottom surface of the pickup door to limit the position of the pickup door in the vertical direction, so that the limiting body can limit the vertical and horizontal directions of the pickup door at the same time, thereby improving the limiting effect of the limiting structure on the pickup door.
[0043] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.
[0044] refer to Figure 1 and Figure 2 An embodiment of the present application discloses a limiting structure of a cargo pickup door, which is used to be installed in a vehicle compartment. The limiting structure includes a limiting body 100.
[0045] The limiting body 100 has a first limiting surface 110 and a second limiting surface 120. The first limiting surface 110 is configured to abut against the side of the pickup door 300 to limit the position of the pickup door 300 in the horizontal direction; the second limiting surface 120 is configured to abut against the bottom surface of the pickup door 300 to limit the position of the pickup door 300 in the vertical direction.
[0046] The cargo pickup door 300 is rotatably connected to the carriage. When the cargo pickup door 300 is in a closed state, the upper end of the cargo pickup door 300 is rotatably connected to the carriage through a hinge, and the lower end of the cargo pickup door 300 abuts against the bottom of the carriage. The limiting structure of the cargo pickup door is installed in the carriage, and the limiting structure is used to abut against the bottom of the cargo pickup door 300 to limit the position of the cargo pickup door 300.
[0047] Exemplarily, the limit body 100 can be fixedly installed in the vehicle compartment, such as by welding, to improve the stability of the limit body 100 installed in the vehicle compartment; the limit body 100 can also be detachably installed in the vehicle compartment, such as by bolts, so that after the limit body 100 is damaged after long-term use, it is convenient for the user to replace the limit body 100, thereby ensuring the limiting effect of the limit body 100 on the pickup door 300.
[0048] Exemplarily, at least two limiting bodies 100 are installed in the vehicle compartment, and the limiting bodies 100 are arranged at intervals to improve the limiting effect of the limiting structure on the cargo pickup door 300.
[0049] Exemplarily, the limiting body 100 is an elastic rubber block, and a notch is set at one end corner of the elastic rubber block, and an L-shaped cross section is formed at the notch, one end face of the L-shaped cross section is a first limiting face 110, and the other end face of the L-shaped cross section is a second limiting face 120, and the other end corners of the elastic rubber block are all arc transitions. When the pickup door 300 abuts against the first limiting face 110 and the second limiting face 120, the limiting body 100 is in an extruded deformation state.
[0050] Exemplarily, the material of the limiting body 100 may be thermoplastic vulcanized rubber or EPDM rubber.
[0051] By adopting the above technical solution, a limiting body 100 is set, and the limiting body 100 has a first limiting surface 110 and a second limiting surface 120. The first limiting surface 110 is configured to abut against the side of the pickup door 300 to limit the position of the pickup door 300 in the horizontal direction; the second limiting surface 120 is configured to abut against the bottom surface of the pickup door 300 to limit the position of the pickup door 300 in the vertical direction, so that the limiting body 100 can limit the vertical and horizontal directions of the pickup door 300 at the same time, thereby improving the limiting effect of the limiting structure on the pickup door 300.
[0052] In some embodiments, the first limiting surface 110 is a first curved surface, and the first curved surface is curved in a direction away from the side of the pickup door 300 .
[0053] Exemplarily, the first curved surface is an arc surface.
[0054] By adopting the above technical solution, by setting the first limiting surface 110 as the first curved surface, and the first curved surface is bent in the direction away from the side of the pickup door 300, when the pickup door 300 is closed, since the first curved surface is bent in the direction away from the side of the pickup door 300, the first curved surface has a guiding function for the side of the pickup door 300, thereby ensuring that when the pickup door 300 is in a closed state, the side of the pickup door 300 is in contact with the first limiting surface 110, thereby ensuring the first limiting surface 110 has a limiting function for the pickup door 300 in the horizontal direction.
[0055] In some embodiments, the second limiting surface 120 is a second curved surface, and the second curved surface is curved in a direction away from the bottom surface of the pickup door 300.
[0056] Exemplarily, the second curved surface is an arc surface.
[0057] By adopting the above technical solution, by setting the second limiting surface 120 as a second curved surface, and the second curved surface is bent in the direction away from the bottom surface of the pickup door 300, when the pickup door 300 is closed, since the second curved surface is bent in the direction away from the bottom surface of the pickup door 300, the second curved surface has a guiding function for the bottom surface of the pickup door 300, thereby ensuring that when the pickup door 300 is in a closed state, the bottom surface of the pickup door 300 is in contact with the second limiting surface 120, thereby ensuring the second limiting surface 120 has a limiting function on the pickup door 300 in the vertical direction.
[0058] In some embodiments, a hollow groove 130 is formed in the middle of the limiting body 100 so that the limiting body 100 is a hollow structure.
[0059] Exemplarily, the limiting body 100 is configured in an L-shape as a whole, and an L-shaped hollow groove 130 is provided inside the limiting body 100, so that the limiting body 100 is an L-shaped frame structure as a whole.
[0060] By adopting the above technical solution, by setting a hollow groove 130 in the middle of the limiting body 100, the deformation of the limiting body 100 is increased, and the tolerance between the limiting body 100 and the pickup door 300 is increased, thereby improving the limiting effect of the limiting structure on the pickup door 300.
[0061] In some embodiments, at least one first reinforcement bar 140 is provided in the hollow groove 130 , and the first reinforcement bar 140 is arranged in a direction perpendicular to the side of the pickup door 300 .
[0062] Exemplarily, one first reinforcing strip 140 is provided.
[0063] Exemplarily, the material of the first reinforcing strip 140 is consistent with the material of the limiting body 100 , such as thermoplastic vulcanized rubber or EPDM rubber.
[0064] Exemplarily, the first reinforcement strip 140 has a first end and a second end relative to each other, the first end is connected to the inner wall of the hollow groove 130 close to the first limiting surface 110, and the second end is connected to the inner wall of the hollow groove 130 away from the first limiting surface 110, and the position where the first end is connected to the hollow groove 130 is directly opposite to the position where the pickup door 300 abuts against the first limiting surface 110.
[0065] By adopting the above technical solution, by setting the first reinforcement strip 140, and the first reinforcement strip 140 is set in a direction perpendicular to the side of the pickup door 300, when the limiting body 100 is deformed by abutting against the side of the pickup door 300, the first reinforcement strip 140 increases the deformation strength of the limiting body 100 in the horizontal direction, thereby ensuring the limiting effect of the limiting body 100 on the side of the pickup door 300.
[0066] In some embodiments, at least one second reinforcement bar 150 is provided in the hollow groove 130 , and the second reinforcement bar 150 is arranged in a direction perpendicular to the bottom surface of the pickup door 300 .
[0067] Exemplarily, one second reinforcing strip 150 is provided.
[0068] Exemplarily, the material of the second reinforcing strip 150 is consistent with the material of the limiting body 100 .
[0069] Exemplarily, the second reinforcement strip 150 has a third end and a fourth end relative to each other, the third end is connected to the inner wall of the hollow groove 130 close to the second limiting surface 120, and the fourth end is connected to the inner wall of the hollow groove 130 away from the second limiting surface 120, and the position where the third end is connected to the hollow groove 130 is directly opposite to the position where the pickup door 300 abuts against the second limiting surface 120.
[0070] By adopting the above technical solution, by setting the second reinforcement strip 150, and the second reinforcement strip 150 is set in a direction perpendicular to the bottom surface of the pickup door 300, when the limiting body 100 is deformed by abutting against the bottom surface of the pickup door 300, the second reinforcement strip 150 increases the deformation strength of the limiting body 100 in the vertical direction, thereby ensuring the limiting effect of the limiting body 100 on the bottom surface of the pickup door 300.
[0071] In some embodiments, the limiting structure of the cargo pickup door further includes a connector 200, which is connected to the limiting body 100, and the connector 200 is configured to install the limiting body 100 in the vehicle compartment.
[0072] For example, the connecting member 200 may be a connecting bolt, and the limiting body 100 has a through hole for the connecting bolt to pass through. The limiting body 100 is installed in the vehicle compartment by passing the connecting bolt through the through hole, so that the limiting body 100 can be detachably installed in the vehicle compartment. After the limiting body 100 is damaged after long-term use, the user can loosen the connecting bolt to remove the limiting body 100, and then replace it with a new limiting body 100, thereby avoiding the limiting body 100 being damaged and inconvenient to replace, thereby affecting the limiting effect of the limiting structure on the pickup door.
[0073] Exemplarily, the connector 200 may be a snap-fitting member, and the position limiting body 100 has a snap-fitting groove for the snap-fitting member to snap-fit, and the position limiting body 100 is snap-fitted into the vehicle compartment via the snap-fitting member, so that the user can install the position limiting body 100 in the vehicle compartment.
[0074] By adopting the above technical solution and providing the connecting member 200 , it is convenient for the user to install the limiting body 100 in the vehicle compartment through the connecting member 200 .
[0075] In some embodiments, the connecting member 200 includes a connecting rod 210 and at least one clamping block 220 .
[0076] The connecting rod 210 is connected to the limiting body 100 .
[0077] The clamping block 220 is disposed on a side of the connecting rod 210 facing away from the limiting body 100 .
[0078] The connecting rod 210 is configured to deform and drive the clamping block 220 to be inserted into the connecting hole when inserted into the connecting hole in the vehicle compartment, so that the clamping block 220 is clamped in the connecting hole.
[0079] Exemplarily, the material of the connecting rod 210 is the same as that of the limiting body 100 , and the connecting rod 210 and the limiting body 100 are integrally formed to reduce the production cost of the limiting structure.
[0080] Exemplarily, two clamping blocks 220 are provided, and the two clamping blocks 220 are symmetrically arranged at two ends of the connecting rod 210 on a side away from the limiting body 100 .
[0081] Exemplarily, the clamping block 220 is a right-angled triangular block, which is disposed on the side of the connecting rod 210 away from the limiting body 100, and the right-angled triangular block is integrally formed with the connecting rod 210, and the inclined surface of the right-angled triangular block is located on the side away from the limiting body 100. When the connecting rod 210 and the clamping block 220 are inserted into the connecting hole, the clamping block 220 can play a guiding role, thereby facilitating the user to insert the connecting rod 210 and the clamping block 220 into the connecting hole.
[0082] Exemplarily, when the connecting rod 210 and the clamping block 220 are inserted into the connecting hole, the connecting rod 210 and the clamping block 220 are deformed. After the clamping block 220 is completely located in the connecting hole, the clamping block 220 restores its original shape, so that one end of the clamping block 220 facing the limiting body 100 is clamped in the connecting hole.
[0083] By adopting the above technical solution, by setting a connecting rod 210 and at least one clamping block 220, when the limit body 100 is installed in the car, the connecting rod 210 and the clamping block 220 are made to face the connecting hole, and then the connecting rod 210 and the clamping block 220 are inserted into the connecting hole until the clamping block 220 is completely embedded in the connecting hole. At this time, the clamping block 220 is clamped in the connecting hole, thereby completing the installation of the limit body 100 in the car, thereby improving the installation effect of the limit body 100 in the car.
[0084] In some embodiments, a through slot 230 is formed in the middle of the connecting rod 210 so that the connecting rod 210 is a hollow rod.
[0085] Exemplarily, the through slot 230 has a waist shape.
[0086] By adopting the above technical solution, by providing a through groove 230 in the middle of the connecting rod 210, the connecting rod 210 is easier to deform, so that it is convenient for the user to insert the connecting rod 210 and the clamping block 220 into the connecting hole.
[0087] The embodiment of the present application also discloses a vehicle, including a compartment, a cargo pickup door 300 connected to the compartment, and a limiting structure of at least one cargo pickup door 300 according to any one of the above embodiments installed in the compartment.
[0088] Among them, the structure and principle of the limiting structure of the pickup door have been clearly explained in the above embodiments, and will not be elaborated here one by one.
[0089] Exemplarily, two limiting structures are provided, and the two limiting structures are arranged in the vehicle compartment at intervals, and the two limiting structures are respectively abutted against two sides of the cargo pickup door 300 to improve the limiting effect of the limiting structure on the cargo pickup door 300.
[0090] By adopting the above technical solution, by setting at least one limiting structure of the cargo pickup door 300 in the vehicle compartment, when the cargo pickup door 300 is in a closed state, the first limiting surface 110 in the limiting structure abuts against the side surface of the cargo pickup door 300 to limit the horizontal position of the cargo pickup door 300; the second limiting surface 120 in the limiting structure abuts against the bottom surface of the cargo pickup door 300 to limit the vertical position of the cargo pickup door 300, so that the limiting body 100 can limit the vertical and horizontal directions of the cargo pickup door 300 at the same time, thereby ensuring the limiting effect of the limiting structure on the cargo pickup door 300.
[0091] In summary, the embodiment of the present application provides a limiting structure for a pickup door, by setting a limiting body 100, the limiting body 100 has a first limiting surface 110 and a second limiting surface 120, the first limiting surface 110 is configured to abut against the side of the pickup door 300 to limit the position of the pickup door 300 in the horizontal direction; the second limiting surface 120 is configured to abut against the bottom surface of the pickup door 300 to limit the position of the pickup door 300 in the vertical direction, so that the limiting body 100 can limit the vertical and horizontal directions of the pickup door 300 at the same time, thereby improving the limiting effect of the limiting structure on the pickup door 300.
[0092] By providing the connecting piece 200 , it is convenient for the user to install the limiting body 100 in the vehicle compartment through the connecting piece 200 .
