Abstract

The present disclosure relates to the technical field of vehicle manufacturing, in particular to a garbage truck and a carriage of the garbage truck. An advantageous effect of the present disclosure is that the carriage comprises a carriage body, a top cover and a sealing element, wherein the carriage body is provided with an opening at least at the top. The top cover is movably connected with the carriage body and is configured to cover the opening.

The elastic portion is arranged on the mounting portion and is configured to have a deformation space in the height direction with the mounting portion in a natural state. When the top cover covers the carriage body, the elastic portion is extruded and deformed under the gravity of the top cover until the sealing element is tightly sealed between the mating surfaces of the top cover and the carriage body.

Since the elastic portion and the mounting portion of the sealing element have a deformation space, the deformation amount of the elastic portion is large when it is subjected to the gravity of the top cover, which is beneficial to ensure the sealing between the top cover and the carriage body.

Description

Technical Field

[0001] This disclosure relates to the field of vehicle manufacturing technology, and in particular to a garbage truck and a garbage truck body. Background Technology

[0002] Garbage trucks on the market typically have an opening at the top to allow for quick loading of garbage. Once the garbage is inside, the top cover closes, sealing the opening and preventing garbage from falling out of the truck during transport due to bumps.

[0003] Currently, the gap between the body and the cover in the market uses a common sealing structure, which involves installing a sealing strip directly on the upper beam of the body to ensure a tight seal between the body and the cover. However, because the sealing strip is impacted every time the cover closes with the body, it deforms. Furthermore, the sealing strip hardens over time and cannot return to its original shape, resulting in a poorer seal between the cover and the body. Utility Model Content

[0004] In order to solve the problem that the sealing performance between the cover and the body deteriorates after long-term use of the sealing strip in the prior art, this disclosure provides a garbage truck and a garbage truck body.

[0005] In a first aspect, this disclosure provides a garbage truck compartment, the compartment comprising:

[0006] The compartment has an opening at least at the top;

[0007] A top cover, which is movably connected to the body and configured to close the opening;

[0008] A sealing element, the sealing element being disposed on the compartment body; and the sealing element comprising:

[0009] The mounting part is connected to the compartment body;

[0010] An elastic part is disposed on the mounting part and is configured to have a deformation space in the height direction with the mounting part in its natural state. When the top cover is closed with the body, the elastic part is squeezed and deformed under the gravity of the top cover until it is sealed and pressed between the mating surfaces of the top cover and the body.

[0011] In one embodiment of this disclosure, the body has an upper beam, the upper beam having a rectangular cross-sectional shape, and an mounting plate extending along the length of the upper beam is provided on the top surface of the upper beam, the width of the mounting plate being smaller than the width of the top surface of the upper beam;

[0012] Furthermore, in the width direction, the mounting plate is located in the middle of the upper beam, and the mounting part has a partition strip and two elastic clamping legs formed by the two ends of the partition strip extending downwards. The mounting part is clamped and straddled on the mounting plate by the two elastic clamping legs.

[0013] In one embodiment of this disclosure, an anti-detachment structure is provided on the clamping surface of the elastic clamping leg, the anti-detachment structure being configured to prevent the mounting portion from moving in a direction detached from the mounting plate.

[0014] In one embodiment of this disclosure, the anti-detachment structure is made of an elastic material, and in its natural state, the anti-detachment structure is an inclined protrusion extending upward and inward simultaneously.

[0015] In one embodiment of this disclosure, in a free state, there is a first gap between the partition strip and the top surface of the mounting plate, and in the height direction, the first gap is smaller than the deformation space.

[0016] In one embodiment of this disclosure, in the height direction, the mounting plate has a connecting surface that connects to the upper beam, and there is a second gap between the connecting surface and the free end of the elastic clamping leg, and the second gap is larger than the first gap.

[0017] In one embodiment of this disclosure, the elastic part is an arched elastic strip, and the two free ends of the arched elastic strip are connected to the two ends of the separator strip.

[0018] In one embodiment of this disclosure, the top of the elastic portion is provided with a thickened portion.

[0019] In one embodiment of this disclosure, the top cover includes an upper mating surface for pressing the elastic portion, and a shielding surface for shielding the mounting plate and the seal when the top cover and the body are closed.

[0020] In one embodiment of this disclosure, the shielding surface includes an inclined surface extending outward from the outer end of the upper mating surface and sloping downward, and a vertical surface extending downward from the free end of the inclined surface;

[0021] Furthermore, when the top cover and the body are in the closed position, there is a third gap between the bottom surface of the vertical surface and the top surface of the upper beam.

[0022] In one embodiment of this disclosure, the included angle between the inclined surface and the upper mating surface is in the range of 30°-40°.

[0023] Secondly, this disclosure provides a garbage transport vehicle having a compartment as described in any one of the above.

[0024] One beneficial effect of this disclosure is that the garbage truck compartment provided by this disclosure includes a body, a top cover, and a sealing element, wherein the body has an opening at least at the top. The top cover is movably connected to the body and is configured to close the opening. The sealing element is disposed on the body and includes a mounting portion and an elastic portion. The mounting portion is connected to the body; the elastic portion is disposed on the mounting portion and is configured to have a deformation space in the height direction with the mounting portion in its natural state. When the top cover and body are closed, the elastic portion is compressed and deformed under the weight of the top cover until it is sealed tightly between the mating surfaces of the top cover and the body.

[0025] The garbage truck provided in this disclosure has a simple compartment structure. Because there is a deformation space between the elastic part and the mounting part of the sealing element, the deformation of the elastic part is large when subjected to the gravity of the top cover, which is beneficial to ensuring the sealing between the top cover and the compartment.

[0026] Meanwhile, due to the existence of deformation space, the elastic part can still maintain good elastic deformation capacity after long-term use, thus extending the service life of the seal.

[0027] Other features and advantages of this disclosure will become clear from the following detailed description of exemplary embodiments with reference to the accompanying drawings. Attached Figure Description

[0046] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0048] To address the problem in existing technologies where the sealing performance between the top cover and the body 1 deteriorates after prolonged use of the sealing strip, this disclosure provides a garbage truck body. The body includes a body 1, a top cover 2, and a sealing element 3.

[0049] The compartment 1 has an opening at least at the top; the top cover 2 is movably connected to the compartment 1 and is configured to close the opening; a sealing element 3 is provided on the compartment 1; and the sealing element 3 includes a mounting part 31 and an elastic part 32. The mounting part 31 is connected to the compartment 1, and the elastic part 32 is provided on the mounting part 31 and is configured to have a deformation space in the height direction with the mounting part 31 in its natural state. When the top cover 2 is closed with the compartment 1, the elastic part 32 is squeezed and deformed under the gravity of the top cover 2 until it is sealed and pressed between the mating surfaces of the top cover 2 and the compartment 1.

[0050] Specifically, such as Figure 1 , 2 As shown in Figure 3, the top of the container 1 is provided with an opening so that garbage can be quickly filled into the container 1 from the top. In practical applications, in addition to the opening at the top, the container 1 can also have an additional opening at the side to remove the garbage from the container 1.

[0051] The top of the compartment 1 is connected to a top cover 2, which is movably connected to the compartment 1. In practical applications, the top cover 2 is connected to the compartment 1 by a hinge. Under the action of the hydraulic system, the top cover 2 can rotate relative to the compartment 1 to expose or close the opening at the top of the compartment 1.

[0052] For example, when workers need to load garbage from the landfill into the container 1, they can control a hydraulic device to rotate the top cover 2 relative to the container 1, thereby exposing the opening at the top of the container 1. Then, with the assistance of a crane or other equipment, workers can quickly load large quantities of garbage into the container 1 through the opening at the top of the container 1.

[0053] The compartment 1 is equipped with a sealing element 3, which is made of elastic material such as rubber. After the top cover 2 is closed with the compartment 1, the sealing element 3 is required to ensure a seal between the top cover 2 and the compartment 1. More specifically, the sealing element 3 is mounted on the compartment 1 via a mounting part 31. In its natural state, the elastic part 32 of the sealing element 3 has a deformation space with the mounting part 31. During the process of the top cover 2 closing with the compartment 1, the top cover 2 presses down and contacts the elastic part 32, causing the elastic part 32 to deform. The elastic part 32 then fits against the upper mating surface 21 of the top cover 2, thereby ensuring the seal between the compartment 1 and the top cover 2.

[0054] The garbage truck body 1 disclosed herein has a simple structure. Because there is a deformation space between the elastic part 32 and the mounting part 31 of the sealing element 3, the elastic part 32 deforms significantly under the gravity of the top cover 2, which helps ensure the sealing performance between the top cover 2 and the body 1. Furthermore, due to the existence of the deformation space, the elastic part 32 can still maintain good elastic deformation capacity after long-term use, extending the service life of the sealing element 3.

[0055] In one embodiment of this disclosure, the box body 1 has an upper beam 12, which is a rectangular upper beam in cross-section. The top surface of the upper beam 12 is provided with an mounting plate 11 extending along the length of the upper beam 12. The width of the mounting plate 11 is smaller than the width of the top surface of the upper beam 12.

[0056] Furthermore, in the width direction, the mounting plate 11 is located in the middle of the upper beam 12, and the mounting part 31 has a partition strip 33 and two elastic clamping legs formed by the two ends of the partition strip 33 extending downward. The mounting part 31 is clamped and straddled on the mounting plate 11 by the two elastic clamping legs.

[0057] Specifically, such as Figure 3 As shown, multiple connecting support beams are provided inside the compartment 1 to enhance its strength. An upper beam 12 is located at one end of the compartment 1 near the top cover 2. A mounting plate 11 is mounted on the top surface of the upper beam 12. This mounting plate 11 can be fixed to the top surface of the upper beam 12 by welding or other methods. The width of the mounting plate 11 is smaller than the width of the top of the upper beam 12 to accommodate the mounting portion 31 of the sealing element 3. This smaller width also facilitates the worker's securement of the mounting plate 11 to the top of the upper beam 12. The mounting plate 11 is positioned in the middle of the upper beam 12, facilitating assembly between the mounting plate 11 and the upper beam 12 of the compartment 1. Furthermore, it allows the upper beam 12 to more stably support the mounting plate 11.

[0058] The mounting portion 31 of the seal 3 has a partition strip 33 to ensure the amount of deformation of the elastic portion 32. The two ends of the partition strip 33 extend downward to form two elastic clamping legs. The mounting portion 31 is clamped and straddled on the mounting plate 11 by the two elastic clamping legs, ensuring that the seal 3 is stably and reliably mounted on the mounting plate 11.

[0059] In practical applications, long-term transport of garbage in the truck body may cause some sticky substances to adhere to the contact surface between the top cover 2 and the seal 3. Alternatively, under high-temperature conditions, such as during outdoor operations in summer, the top cover 2 and the seal 3 may partially stick together. When the top cover 2 is opened, it may pull the seal 3 upwards, causing the seal 3 to detach from the truck body 1.

[0060] In response to the above situation, in one embodiment of this disclosure, an anti-detachment structure 311 is provided on the clamping surface of the elastic clamping leg. The anti-detachment structure 311 is configured to prevent the mounting part 31 from moving in the direction away from the mounting plate 11.

[0061] The sealing element 3 of the carriage provided in this disclosure has an anti-detachment structure 311 on the clamping surface of the elastic clamping leg. The anti-detachment structure 311 is also made of elastic material, which can increase the friction between the sealing element 3 and the mounting plate 11 and prevent the mounting part 31 from moving in the direction away from the mounting plate 11. The anti-detachment structure 311 will be described in detail with reference to the following two embodiments.

[0062] Example 1:

[0063] like Figure 4 , 5 As shown, the seal 3 has a raised strip on the clamping surface of the elastic clamping leg. After the seal 3 is installed on the mounting plate 11, the raised strip on the clamping surface is squeezed by the mounting plate 11 and the elastic clamping leg, which increases the friction between the seal 3 and the mounting plate 11 and reduces the possibility of the seal 3 falling off the mounting plate 11.

[0064] Example 2:

[0065] like Figure 6 As shown, in this embodiment, the seal 3 has an inclined protrusion on the clamping surface of the elastic clamp leg.

[0066] During the installation of the seal 3 on the mounting plate 11, since the mounting plate 11 is inserted into the seal 3 along the inclined direction of the inclined protrusion, the inclined protrusion deforms. At this time, the friction between the seal 3 and the mounting plate 11 is reduced, which is beneficial to the installation of the seal 3.

[0067] When the top cover 2 and the seal 3 are bonded together, and the top cover 2 is pulled upwards while the seal 3 is being opened, the inclined protrusion is subjected to a force along the inclined direction. In this case, the force on the inclined protrusion increases, and the frictional force fed back to the seal 3 also increases accordingly, making it less likely for the seal 3 to fall off relative to the mounting plate 11.

[0068] In one embodiment of this disclosure, in the free state, there is a first gap between the partition strip 33 and the top surface of the mounting plate 11, and in the height direction, the first gap is smaller than the deformation space.

[0069] During assembly, a first gap should be maintained between the separator strip 33 of the seal 3 and the top surface of the mounting plate 11. This allows the seal 3 to be higher in the height direction, making it easier for it to contact the top cover 2 and deform, thus achieving a seal. Furthermore, the presence of this first gap also prevents the edges and corners of the mounting plate 11 from excessively compressing the interior of the seal 3, which could damage the seal 3.

[0070] However, it should be noted that the first gap should be smaller than the deformation space to ensure the contact area between the seal 3 and the mounting plate 11 and to ensure the connection stability between the seal 3 and the mounting plate 11.

[0071] In one embodiment of this disclosure, in the height direction, the mounting plate 11 has a connecting surface that connects to the upper beam 12, and the connecting surface has a second gap with the free end of the elastic clamping leg, and the second gap is larger than the first gap.

[0072] like Figure 3 As shown, the height of the mounting plate 11 is greater than the height of the elastic clamping leg. After the seal 3 is installed on the mounting plate 11, there is a second gap between the connecting surface of the mounting plate 11 and the upper beam 12 and the free end of the elastic clamping leg. This prevents the elastic clamping leg from being too long and directly contacting the connecting surface. The specific reasons are as follows:

[0073] The top cover 2 presses down and exerts a force on the seal 3. If the elastic clamping leg directly contacts the connecting surface of the upper beam 12, it may cause the side walls of the seal 3 on both sides of the first gap to deform and bend after being subjected to force. Long-term reciprocating bending will cause damage to the dividing strip and the elastic clamping leg, especially at the connection end of the two.

[0074] Therefore, the sealing element 3 of the compartment 1 provided in this disclosure leaves a second gap between the elastic clamp leg and the mounting surface of the upper beam 12, which can prevent damage to the connection end of the dividing strip and the elastic clamp leg and ensure the service life of the sealing element 3.

[0075] In one embodiment of this disclosure, the elastic part 32 is an arched elastic strip, and the two free ends of the arched elastic strip are connected to the two ends of the separator 33.

[0076] As mentioned above, the sealing element 3 of this disclosure is provided with a partition strip 33 to ensure the deformation of the elastic part 32 and to prevent the mounting plate 11 from directly abutting against the elastic part 32, which would reduce the deformation of the elastic part 32 and thus affect its sealing performance.

[0077] The elastic part 32 of this disclosure is configured as an arched elastic strip. During the contact process between the top cover 2 and the elastic part 32, the elastic part 32 and the top cover 2 are in line contact at the beginning of contact. As the top cover 2 is pressed down, the contact between the elastic part 32 and the top cover 2 changes to surface contact.

[0078] During the docking process between the top cover 2 and the elastic part 32, the top cover 2 rotates relative to one end of the body 1 and presses down during the rotation. Therefore, from the moment the top cover 2 and the elastic part 32 first come into contact until the top cover 2 stops pressing down, from one point of view, the top cover 2, in addition to its downward movement, also actually includes outward movement. Therefore, in addition to squeezing the elastic part 32, the top cover 2 also moves slightly relative to the elastic part 32. During this process, the top cover 2 and the elastic part 32 rub against each other, wearing down the surface of the elastic part 32.

[0079] In the elastic part 32 of the disclosed carriage, the arched shape ensures that the aforementioned wear is concentrated only at the very top of the elastic part 32, while the wear on both sides of the top of the elastic part 32 gradually decreases. Therefore, the arched elastic part 32 helps to reduce the wear of the sealing element 3 on the top cover 2 during opening and closing, thus ensuring the service life of the sealing element 3.

[0080] Regarding the aforementioned issue that wear on the elastic portion 32 in this disclosure primarily occurs at the very top, in one embodiment provided in this disclosure, a thickened portion is provided at the top of the elastic portion 32. This disclosure also provides Embodiment Three, which improves upon the seal 3.

[0081] Example 3:

[0082] like Figure 7 As shown, in this embodiment, a thickened portion is provided at the top of the elastic part 32, making the wall thickness at the top greater than the wall thickness at other locations of the elastic part 32. This thickening of the top of the elastic part 32 makes it more wear-resistant and extends the service life of the seal 3. Furthermore, the form shown in the figure is easier to manufacture.

[0083] In one embodiment of this disclosure, the top cover 2 includes an upper mating surface 21 for compressing the elastic portion 32, and a shielding surface for shielding the mounting plate 11 and the seal 3 when the top cover 2 and the body 1 are closed.

[0084] like Figure 3 As shown, the outer side of the top cover 2 is provided with a shielding surface for the mounting plate 11 and the sealing element 3, which helps to reduce the impact of the external environment on the mounting plate 11 and the sealing element 3, especially the sealing element 3, such as strong sunlight and rain, which can cause the sealing element 3 to age prematurely and thus affect its service life.

[0085] In one embodiment of this disclosure, the shielding surface includes an inclined surface 22 extending outward from the outer end of the upper mating surface 21 and inclined downward, and a vertical surface 23 extending downward from the free end of the inclined surface 22; and when the top cover 2 and the body 1 are in the closed position, there is a third gap between the bottom surface of the vertical surface 23 and the top surface of the upper beam 12.

[0086] When the carriage provided in this disclosure is operating in rainy weather, rainwater falls onto the top cover 2 and flows down along it. Guided by the vertical surface 23, the rainwater can only fall outside the carriage 1 and cannot come into contact with the seal 3. At the same time, the inclined surface 22 is used to connect the end of the vertical surface 23 with the mating surface 21 of the top cover 2, which can ensure the overall strength of the top cover 2 and prevent the vertical surface 23 from forming a cantilever structure, which would cause a large degree of deformation after being subjected to external impact.

[0087] In addition, when the top cover 2 and the body 1 are in the closed position, there is a third gap between the bottom surface of the vertical surface 23 and the top surface of the upper beam 12. The third gap can ensure the tight fit between the sealing element 3 and the top cover 2, and ensure the sealing between the body 1 and the top cover 2.

[0088] To ensure the connection strength between the main body of the top cover 2 and the vertical surface 23, and to ensure that during the pressing down of the top cover 2, the sealing element 3 only contacts the upper mating surface 21 of the top cover 2 and not the inclined surface 22, thus avoiding additional wear on the sealing element 3, in one embodiment of this disclosure, the included angle between the inclined surface 22 and the upper mating surface 21 is in the range of 30°-40°.

[0089] Secondly, this disclosure also provides a garbage transport vehicle with the aforementioned compartment. The garbage transport vehicle using the compartment provided by this disclosure has good sealing performance between the top cover 2 and the compartment 1, and a long service life.

[0090] To facilitate understanding, the carriage provided in this disclosure will be explained below with an application scenario in mind.

[0091] When workers need to load garbage from the landfill into container 1, they can control a hydraulic device to rotate the top cover 2 relative to container 1, thus revealing an opening at the top of container 1. Then, with the assistance of cranes and other equipment, workers can quickly load large quantities of garbage into container 1 through the opening at the top of container 1.

[0092] Subsequently, the staff controlled the hydraulic device to close the top cover 2 and the body 1. During this process, the top cover 2 pressed down on the elastic part 32 of the sealing element 3. The elastic part 32 deformed and the top of the sealing element 21 made close contact with the mating surface 21 of the top cover 2, thus achieving the sealing between the top cover 2 and the body 1.

[0093] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
