[0048] As described in the background, at present, with the rapid development of cold chain logistics industry, as a transport equipment for guaranteeing the quality of goods, the sealing performance and heat insulation performance of the compartment structure of the refrigerated vehicle directly affect the quality of goods in the refrigerated vehicle.

[0049] The compartment structure of the refrigerated vehicle includes a plurality of compartment plates made of heat insulation material to ensure the heat preservation performance of the refrigerated vehicle. When installing, the compartment plates are connected with the vehicle body by using adhesive, and are positioned and extruded by wood blocks in the compartment body to ensure the stability of the connection between the compartment plates and the vehicle body, and prevent the movement of the compartment plates.

[0050] However, in actual operation, the length of the wood block needs to be selected or cut according to different vehicle compartments, resulting in high installation difficulty and low installation efficiency.

[0051] To solve the above problems, the embodiment of the present application provides a positioning structure and a vehicle. The positioning structure comprises a support assembly arranged in a compartment; at least one first positioning assembly arranged on the support assembly, the first positioning assembly comprising two first abutting portions configured to move relative to each other in a first direction to abut or disengage from the opposite sides of the compartment; and at least one second positioning assembly arranged on the support assembly, the second positioning assembly comprising at least one second abutting portion configured to move in a second direction to abut or disengage from the top surface of the compartment. The arrangement of the first positioning assembly and the second positioning assembly can simultaneously achieve the compression and positioning of the compartment in the first direction and the second direction, greatly improving the installation efficiency and reducing the installation difficulty. In addition, the first positioning assembly and the second positioning assembly can be adaptively adjusted according to different compartments, improving the adaptability of the positioning structure.

[0052] The technical solutions of the present application and how the technical solutions solve the above technical problems will be 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 described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0053] Figure 1 The structural diagram of the positioning structure provided by the embodiment of the present application is shown.

[0054] Please refer to Figure 1 . In a first aspect, the embodiment provides a positioning structure, comprising a support assembly 100 arranged in a compartment; at least one first positioning assembly 200 arranged on the support assembly 100, the first positioning assembly 200 comprising two first abutting portions 220 configured to move relative to each other in a first direction to abut or disengage from the opposite sides of the compartment; and at least one second positioning assembly 300 arranged on the support assembly 100, the second positioning assembly 300 comprising at least one second abutting portion 330 configured to move in a second direction to abut or disengage from the top surface of the compartment.

[0055] Specifically, the compartment comprises a plurality of compartment plates, such as side plates, top plates and bottom plates. Each compartment plate is connected to the vehicle body and connected by an adhesive, thereby forming a closed refrigeration space to facilitate the transportation of temperature-sensitive goods such as fresh food, pharmaceutical products, etc.

[0056] In the installation of the panel, in order to ensure the tightness of the connection between the compartment and the vehicle body, a wooden block is usually arranged in the compartment, and the wooden block is abutted with each panel of the compartment, so that the panel is pressed on the vehicle body to ensure the tightness of the connection between the panel and the vehicle body, and displacement of the panel is avoided.

[0057] However, the positioning and pressing by the wooden block cannot be adjusted in length, and different wooden blocks need to be selected for different sizes of refrigerated vehicles. Meanwhile, the installation of the wooden block is difficult, and the operator usually needs to repeatedly measure, cut and adjust the length of the wooden block to adapt to the size of the compartment of the refrigerated vehicle. If the length of the wooden block is not accurate, the pressing force may be uneven, affecting the connection effect between the panel and the vehicle body.

[0058] To solve the above problems, the embodiment provides a positioning structure, which comprises a support assembly 100, a first positioning assembly 200 and a second positioning assembly 300. The support assembly 100 serves as a basic bearing platform and is placed on the bottom surface of the compartment. The first positioning assembly 200 and the second positioning assembly 300 are arranged on the support assembly 100.

[0059] When positioning is needed, the two first abutting portions 220 of the first positioning assembly 200 can move away from each other along the first direction to abut on the two opposite sides of the compartment along the first direction, thereby realizing the pressing and positioning of the panel along the first direction. The second abutting portion 330 of the second positioning assembly 300 can move along the second direction to abut on the top surface of the compartment, thereby cooperating with the support assembly 100 to realize the pressing and positioning of the panel along the second direction.

[0060] When disassembling, the operator only needs to move the two first abutting portions 220 relatively close to disengage from the abutment with the compartment, and move the second abutting portion 330 in the reverse direction along the second direction to disengage from the abutment with the compartment, so as to realize the disassembly of the positioning structure, which is simple in operation and greatly improves the operation efficiency.

[0061] Specifically, since the first abutting portion 220 can move along the first direction and the second abutting portion 330 can move along the second direction, when the compartment of different refrigerated vehicles is used, the moving distance of the first abutting portion 220 and the second abutting portion 330 can be adaptively adjusted, so that different specifications of the positioning structure are not needed to be customized, and the adaptability is significantly improved.

[0062] In addition, it should be noted that the operator can adaptively select the specific structure for realizing the movement of the first abutting portion 220 and the second abutting portion 330, and the embodiment does not make any limitation thereon. For example, a push rod motor or a lead screw motor can be used as the driving structure.

[0063] In an optional embodiment, the first positioning assembly 200 comprises a second crossbar 210 arranged on the support assembly 100 in the first direction, two first abutting portions 220 arranged at opposite ends of the second crossbar 210, and a first driving member 230 arranged on the second crossbar 210, the first driving member 230 being configured to drive the two first abutting portions 220 to move towards or away from each other in the first direction to abut against or disengage from the opposite sides of the compartment body, respectively.

[0064] Specifically, in the present embodiment, the second crossbar 210 is arranged on the support assembly 100 in the first direction. The two first abutting portions 220 are arranged at opposite ends of the second crossbar 210, and the two first abutting portions 220 can be synchronously moved towards or away from each other in the first direction by the driving of the first driving member 230, thereby achieving precise pressing and positioning of the two side surfaces of the compartment body in the first direction, i.e., the horizontal direction.

[0065] In the present embodiment, the second crossbar 210 is of a hollow structure, and the two first abutting portions 220 are arranged inside the second crossbar 210 and located at opposite ends of the second crossbar 210. The two first abutting portions 220 can be synchronously moved towards or away from each other in the first direction by the driving of the first driving member 230, thereby achieving precise pressing and positioning of the two side surfaces of the compartment body.

[0066] In an optional embodiment, the first driving member 230 is a push rod motor, and the number of the first driving members 230 is two. The two push rod motors are arranged in one-to-one correspondence with the two first abutting portions 220, respectively, to control the first abutting portions 220 to extend into or out of the second crossbar 210. Specifically, when pressing and positioning are needed, the two push rod motors control the two first abutting portions 220 to gradually extend into the second crossbar 210 until abutting against the side surfaces of the compartment body.

[0067] In other embodiments, the number of the first driving members 230 can also be one, and the first driving member 230 can drive the two first abutting portions 220 by means of a bidirectional screw, so that the two first abutting portions 220 can move synchronously.

[0068] In an optional embodiment, the contact surface of the first abutting portion 220 is provided with a self-adaptive rubber pad, which can compensate for the unevenness of the surface of the compartment plate, and increase the friction coefficient through anti-slip patterns to ensure uniform distribution of the pressing force. The first abutting portion 220 is provided with a built-in pressure sensor, which can monitor the pressing force in real time and perform closed-loop adjustment through a control system to ensure that the pressing force is always within the set range.

[0069] In an alternative embodiment, the second crossbar 210 is slidingly arranged on the support assembly 100, the support assembly 100 is provided with a plurality of first limiting holes 111, and the second crossbar 210 is provided with second limiting holes, and the first locking member 500 is sequentially inserted into the second limiting holes and the first limiting holes 111 to connect the second crossbar 210 and the support assembly 100.

[0070] Specifically, in the embodiment, the second crossbar 210 is slidingly arranged on the support assembly 100 and can move up and down along the second direction to adjust the height thereof relative to the bottom surface of the compartment to meet the positioning requirements of the refrigerated van compartment plate at different heights.

[0071] The support assembly 100 is provided with a plurality of first limiting holes 111, which are uniformly distributed along the height direction of the support assembly 100, and the second crossbar 210 is provided with second limiting holes corresponding to the first limiting holes 111, the height of the second crossbar 210 is adjusted by sliding the second crossbar 210 along the support assembly 100, and then the first locking member 500 is sequentially inserted into the second limiting holes and the first limiting holes 111 to fix the second crossbar 210 and the support assembly 100 together, so as to ensure that the second crossbar 210 remains stable after the height adjustment.

[0072] In actual operation, the operator first adjusts the height of the second crossbar 210 along the support assembly 100 to a proper position according to the height requirement of the compartment, aligns the second limiting holes with a certain first limiting hole 111 on the support assembly 100, and then inserts the first locking member 500 into the second limiting holes and the first limiting hole 111 to ensure that the connection between the second crossbar 210 and the support assembly 100 is firm and reliable.

[0073] In an alternative embodiment, the first locking member 500 is a bolt, and after the first locking member 500 is inserted into the first limiting hole 111 and the second limiting hole, the operator can use a nut to fix the bolt, thereby further improving the stability of the connection between the second crossbar 210 and the support assembly 100.

[0074] In an alternative embodiment, the second positioning assembly 300 includes a fixing member 310 connected to the support assembly 100, the fixing member 310 is provided with a threaded hole along the second direction, a rotating member 320 connected to the second abutting portion 330, the rotating member 320 is engaged with the threaded hole, and the rotating member 320 is rotated to make the second abutting portion 330 abut against or be separated from the top surface of the compartment.

[0075] Specifically, in the embodiment, the fixing member 310 is connected with the support assembly 100 to support the rotating member 320 and the second abutting portion 330. The fixing member 310 can be fixed on the support assembly 100 by a bolt or a mounting buckle, etc., to ensure the stability of the fixing member 310. The fixing member 310 is provided with a threaded hole in the second direction, and the internal thread of the threaded hole is engaged with the external thread of the rotating member 320 to form a threaded transmission mechanism. The pitch and depth of the threaded hole are designed according to actual requirements to ensure that the rotating member 320 can move smoothly during rotation and at the same time provide sufficient pressing force.

[0076] The rotating member 320 is connected with the second abutting portion 330, and the external thread of the rotating member 320 is engaged with the threaded hole of the fixing member 310. When the operator rotates the rotating member 320 clockwise, the second abutting portion 330 moves upward along the threaded hole until it is tightly abutted on the top surface of the compartment body. When the rotating member 320 is rotated counterclockwise, the second abutting portion 330 moves downward and is separated from the compartment body. The rotation angle of the rotating member 320 is proportional to the moving distance of the second abutting portion 330, and the operator can accurately control the pressing force by observing the scale mark or using a torque wrench.

[0077] In an optional embodiment, the contact surface of the second abutting portion 330 is designed with an adaptive rubber pad, which can compensate for the unevenness of the surface of the compartment plate, and at the same time increase the friction coefficient through the anti-skid pattern to ensure that the pressing force is uniformly distributed. The second abutting portion 330 is provided with a pressure sensor, which can monitor the pressing force in real time and perform closed-loop adjustment through the control system to ensure that the pressing force is always within the set range.

[0078] The second positioning assembly 300 provided in the embodiment is threadedly connected with the fixing member 310 and the rotating member 320, which not only enhances the stability and reliability of the positioning in the second direction, but also improves the adaptability and flexibility of the positioning structure, and can meet the installation requirements of the compartment plates of refrigerated vehicles with different sizes and structures.

[0079] In addition, it should be noted that in the embodiment, each second positioning assembly 300 includes two rotating members 320 and two second abutting portions 330, and the fixing member 310 is arranged on the support assembly 100. Two threaded holes are arranged at the two ends of the fixing member 310, respectively, and the two rotating members 320 are arranged in the threaded holes, respectively, so as to ensure the stability of the abutment of the second positioning assembly 300.

[0080] In an optional embodiment, the second positioning assembly 300 can slide on the support assembly 100 in the first direction, so that the operator can adjust the position of the second positioning assembly 300 to adaptively select the positioning and pressing position of the second positioning assembly 300 on the compartment body.

[0081] In an optional embodiment, the second positioning assembly 300 further comprises a second driving member, an output end of the second driving member being connected with the rotating member 320, and the second driving member is configured to drive the rotating member 320 to rotate so as to drive the second abutting part 330 to move in the second direction.

[0082] Specifically, in the embodiment, the second driving member is configured to drive the rotating member 320 to rotate so as to drive the second abutting part 330 to abut against or be separated from the top surface of the compartment, which realizes the automatic driving of the rotating member 320, thereby significantly improving the adjustment efficiency and accuracy of the second abutting part 330.

[0083] The mounting position of the second driving member can be selected according to actual needs, for example, being directly fixed on the fixed member 310 or being mounted near the support assembly 100 through a support. The output shaft of the second driving member and the rotating member 320 are connected in a rigid or flexible manner, which ensures the stability and reliability of power transmission. For example, when the second driving member is started, the output shaft drives the rotating member 320 to rotate through a shaft coupling, so that the second abutting part 330 moves upward along the threaded hole until it is tightly abutted against the top surface of the compartment; when disassembly is needed, the second driving member is reversely operated to drive the rotating member 320 to reversely rotate, so that the second abutting part 330 moves downward and is separated from the compartment.

[0084] In an optional embodiment, the positioning structure further comprises a third positioning assembly 400, the third positioning assembly 400 being arranged on the support assembly 100, and the third positioning assembly 400 is configured to move in a third direction to abut against or be separated from the side of the compartment opposite to the compartment door.

[0085] Specifically, in the design of the compartment of the refrigerated vehicle, one side is usually provided with a compartment door for loading and unloading of goods. That is, in the third direction, both sides do not need to be simultaneously pressed, and only the side without the compartment door needs to be pressed.

[0086] It should be noted that, in the embodiment, the compartment has a rectangular structure, the first direction is the horizontal direction of the compartment, the second direction is the vertical direction of the compartment, and the third direction is the longitudinal direction of the compartment.

[0087] Specifically, in the embodiment, the third positioning assembly 400 is used to realize the positioning and pressing of the compartment in the third direction, so that the positioning structure can realize the simultaneous positioning and pressing of the compartment in the first direction, the second direction and the third direction, thereby greatly improving the installation efficiency and being suitable for large-scale production.

[0088] In an optional embodiment, the third positioning assembly 400 comprises a third crossbar 410 arranged in the third direction, one end of the third crossbar 410 being connected to the support assembly 100; a third abutting part 420 connected to one end of the third crossbar 410 away from the support assembly 100; and a third driving part 430 arranged on the third crossbar 410, the third driving part 430 being configured to drive the third abutting part 420 to move in the third direction so that the third abutting part 420 abuts against or is separated from the side of the compartment body opposite to the compartment door.

[0089] Specifically, in the present embodiment, the third crossbar 410 is arranged in the third direction, one end of the third crossbar 410 being connected to the support assembly 100, and the third crossbar 410 is of a hollow structure, and the third abutting part 420 is arranged in the third crossbar 410 away from the support assembly 100. When the pressing positioning operation is needed, the third driving part 430 drives the third abutting part 420 to gradually extend out of the third crossbar 410 in the third direction and abut against the side of the compartment body in the third direction.

[0090] Specifically, since in the third direction, pressing is not needed on both sides at the same time, but only on the side without the compartment door. Therefore, the number of the third abutting part 420 in the present embodiment is one, which abuts against the side of the compartment body opposite to the compartment door.

[0091] In an optional embodiment, the contact surface of the third abutting part 420 is provided with an adaptive rubber pad, which can compensate for the unevenness of the surface of the compartment plate, and at the same time, increase the friction coefficient through the anti-slip pattern to ensure uniform distribution of the pressing force. The third abutting part 420 is provided with a pressure sensor, which can monitor the pressing force in real time and perform closed-loop adjustment through the control system to ensure that the pressing force is always within the set range.

[0092] In an optional embodiment, the number of the third positioning assembly 400 can be multiple, and the multiple third positioning assemblies 400 are arranged in the second direction, i.e., the height direction of the support assembly 100, so as to realize multi-point extrusion of the compartment body and ensure the stability of the fixed compartment plate.

[0093] In an optional embodiment, the third crossbar 410 is slidingly arranged on the support assembly 100, and the support assembly 100 is provided with multiple third limiting holes 112, and the third crossbar 410 is provided with a fourth limiting hole, and the second locking part 600 passes through the third limiting hole 112 and the fourth limiting hole in sequence to connect the third crossbar 410 and the support assembly 100.

[0094] Specifically, in the present embodiment, the third crossbar 410 is slidingly arranged on the support assembly 100 and can move up and down in the second direction, so as to adjust the height thereof relative to the bottom surface of the compartment body to meet the positioning needs of the compartment plate of the refrigerated vehicle at different heights.

[0095] A plurality of third limiting holes 112 are formed on the support assembly 100 and are uniformly distributed along the length direction of the support assembly 100. A fourth limiting hole corresponding to the third limiting hole 112 is formed on the third cross bar 410. The height of the third cross bar 410 is adjusted by sliding the third cross bar 410 along the support assembly 100. The second locking member 600 is then inserted into the third limiting hole 112 and the fourth limiting hole to fix the third cross bar 410 and the support assembly 100 together, ensuring that the third cross bar 410 remains stable after the height adjustment.

[0096] In actual operation, the operator first adjusts the height of the compartment according to the height requirement, and then slides the third cross bar 410 along the support assembly 100 to the appropriate position, so that the fourth limiting hole is aligned with a certain third limiting hole 112 on the support assembly 100. Then the second locking member 600 is inserted into the third limiting hole 112 and the fourth limiting hole to ensure that the connection between the third cross bar 410 and the support assembly 100 is firm and reliable.

[0097] In an alternative embodiment, the second locking member 600 is a bolt. After the second locking member 600 is inserted into the third limiting hole 112 and the fourth limiting hole, the operator can use a nut to fix the bolt, thereby further improving the stability of the connection between the third cross bar 410 and the support assembly 100.

[0098] In an alternative embodiment, the support assembly 100 includes at least one longitudinal rod 110 arranged in the compartment along a second direction, and the first positioning assembly 200 is arranged on the longitudinal rod 110. The first cross bar 120 is arranged on the longitudinal rod 110 along a first direction, and the second positioning assembly 300 is arranged on the first cross bar 120.

[0099] Specifically, in this embodiment, the support assembly 100 includes at least one longitudinal rod 110 arranged in the compartment along a second direction. As the core support part of the support assembly 100, the first cross bar 120 is arranged on the longitudinal rod 110 along a first direction, forming a "cross" or "T" structure with the longitudinal rod 110, to facilitate the installation of the first positioning assembly 200 and the second positioning assembly 300.

[0100] The first positioning assembly 200 is arranged on the longitudinal rod 110 to achieve the compression and positioning of the compartment in the horizontal direction. The second positioning assembly 300 is arranged on the cross bar. When the second abutting portion 330 of the second positioning assembly 300 abuts against the top surface of the compartment, the reaction force from the top surface of the compartment is transmitted to the longitudinal rod 110, so that the longitudinal rod 110 can stably support the bottom surface of the compartment, achieving the compression and positioning of the bottom surface of the compartment.

[0101] The first positioning assembly 200 and the second positioning assembly 300 can be multiple in number to improve the compression positioning capability of the compartment. The multiple first positioning assemblies 200 are arranged on the longitudinal rod 110 along the second direction, and the multiple second positioning assemblies 300 are arranged on the first cross rod 120 along the first direction.

[0102] Specifically, in the embodiment, the longitudinal rod 110 can be multiple in number, and the multiple longitudinal rods 110 are arranged in parallel along the second direction and uniformly distributed in the compartment to enhance the stability and load-bearing capacity of the support assembly 100.

[0103] Meanwhile, in the embodiment, one end of the longitudinal rod 110 at the interface with the bottom surface of the compartment is provided with a cushion block to ensure the stability and adaptability of the longitudinal rod 110.

[0104] The cushion block is made of a material with certain elastic deformation capacity, such as rubber. The surface of the cushion block can be provided with anti-skid lines adaptively to increase the friction between the cushion block and the bottom surface of the compartment, avoiding the sliding or displacement of the support assembly 100. The thickness of the cushion block can be adaptively adjusted according to actual needs to compensate for the unevenness of the bottom surface of the compartment, ensuring that the contact surface between the longitudinal rod 110 and the bottom surface of the compartment is uniformly stressed, and avoiding deformation or damage caused by stress concentration at the contact point between the longitudinal rod 110 and the bottom surface of the compartment.

[0105] In a second aspect, the embodiment provides a vehicle including a vehicle body and the positioning structure according to any one of the first aspect.

[0106] The specific structure of the positioning structure has been described in the above embodiment, and will not be repeated here.

[0107] The positioning structure and the vehicle provided by the embodiment can realize the compression and positioning of the compartment along the first direction and the second direction simultaneously through the arrangement of the first positioning assembly 200 and the second positioning assembly 300, greatly improving the installation efficiency. In addition, the first positioning assembly 200 and the second positioning assembly 300 can be adaptively adjusted according to different compartments, improving the adaptability of the positioning structure.

[0108] It should be understood that many variations can be made in the embodiments described and shown which should be considered within the scope of the present application as defined by the appended claims.
