Technical Field

[0001] This application relates to the field of new energy vehicle technology, specifically to a chassis and new energy equipment. Background Technology

[0002] With the development of the new energy industry, the application of electrification technology in new energy equipment is becoming increasingly widespread.

[0003] In conventional electric vehicles, batteries are mounted on the chassis, typically by assembling multiple batteries into a module and then securing it to the chassis's top cover. This structure encroaches on the installation space for other components. When the new energy equipment is used in engineering vehicles such as truck cranes, this mounting position can hinder the crane's loading and unloading operations and makes battery installation and removal difficult. In truck cranes, especially hybrid and pure electric cranes, the large battery capacity and space requirements exacerbate these problems if the method of assembling multiple batteries into a module and securing it to the chassis's top cover is still used.

[0004] Therefore, a new chassis needs to be developed to save space and facilitate battery installation and removal. Summary of the Invention

[0010] In another embodiment, the chassis includes a second mounting module that passes through a mounting hole and is connected to a first mounting module. Each first mounting module corresponds to one second mounting module, and each second mounting module contains at least one battery.

[0014] In another embodiment, a limit structure is provided on any one or more of the first sliding joint, the second sliding joint, and the third sliding joint.

[0015] Secondly, this application provides a new energy device, which includes the aforementioned chassis.

[0016] With the above configuration, the chassis structure of this application is compact. By arranging multiple batteries in blocks, more batteries can be provided within a limited space for use by new energy equipment.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] In this application, it should be noted that "longitudinal" refers to the forward direction of the new energy equipment; "up" and "down" are relative to the ground when working normally, with "down" being closer to the ground and "up" being farther from the ground; "lateral" refers to the width direction of the new energy equipment, which is perpendicular to the direction of travel; "front" refers to the forward direction of the new energy equipment when it is driving normally; and "rear" refers to the direction opposite to "front".

[0044] To better understand this application, the following description is based on specific embodiments and in conjunction with the accompanying drawings.

[0045] Firstly, see [the following] Figures 1-6 As shown, this application provides a chassis including a frame 1 with a first mounting compartment 11. The entrance and exit of the first mounting compartment 11 are located on the side of the frame 1, and a mounting through hole 111 communicating with the first mounting compartment 11 is formed on the bottom plate of the frame 1. The chassis includes a first mounting module 21, which is configured to be slidably installed into the first mounting compartment 11 from the entrance and exit of the first mounting compartment 11 through a first sliding pair. The side of the first mounting module 21 facing the mounting through hole 111 can be connected to a second mounting module 22 located outside the first mounting compartment 11 through the mounting through hole 111. At least one first mounting module 21 is provided in the first mounting compartment 11, and at least one battery 5 is installed in each first mounting module 21. With the above arrangement, multiple batteries are arranged in blocks, and the chassis structure of this application is compact and space-saving, which can provide more batteries in a limited space, especially suitable for new energy equipment that requires large-capacity batteries. It can greatly increase the battery capacity of the new energy vehicle and extend the working time of the new energy equipment. By placing the entrance and exit of the first mounting compartment on the side of the chassis, the battery can be quickly installed and removed by accessing the first mounting module. Even if the battery is heavy, it can usually be installed and removed with just a forklift. By setting the mounting through hole on the first mounting compartment, the first mounting module can be connected to the second mounting module located outside the first mounting compartment by passing through the mounting through hole. This can make use of the limited space of the chassis to provide installation positions and protection for multiple mounting modules.

[0046] Typically, the entrance and exit of the first installation compartment 11 are located on the left or right side of the base frame 1. If necessary, the first installation compartment 11 may also have entrances and exits on both the left and right sides of the base frame 1.

[0047] exist Figures 5-6In one embodiment shown, the base frame 1 has two first mounting compartments 11 arranged side-by-side in the transverse direction of the base frame 1. These two first mounting compartments 11 are symmetrically arranged along the longitudinal centerline of the base frame 1. Each first mounting compartment 11 corresponds to two mounting through holes 111. That is, the base frame 1 has two first mounting compartments 11, and the base plate of the base frame 1 has a total of four mounting through holes 111. Here, the number of mounting through holes 111 and the number of first mounting compartments 11 can be set as needed. One first mounting compartment 11 can correspond to one mounting through hole 111, multiple adjacent first mounting compartments 11 can correspond to one mounting through hole 111, or one first mounting compartment 11 can correspond to multiple mounting through holes 111, as long as it allows the second mounting module 22 to extend from the outside of the base frame 1 into the mounting through hole 111 and connect with the first mounting module 21. Figure 5 and Figure 6 The chassis in the example belongs to the case where one first mounting compartment 11 corresponds to multiple mounting through holes 111.

[0048] In another embodiment, the base frame 1 is provided with two rows of first installation compartments 11 arranged side by side along the transverse direction of the base frame 1. The two rows of first installation compartments 11 are symmetrically arranged along the longitudinal center line of the base frame 1. That is to say, the inlets and outlets of the two rows of first installation compartments 11 are respectively opened on the left and right sides of the base frame 1.

[0049] In another embodiment, reference Figure 1 , Figures 4-6 , Figure 8 , Figures 11-12 , Figure 24 As shown, the chassis includes a second mounting module 22, which connects to the first mounting module 21 through a mounting hole 111. Each first mounting module 21 corresponds to one second mounting module 22, and each second mounting module 22 contains at least one battery 5. This arrangement results in a compact layout, saving space and costs. For engineering vehicles, especially truck cranes, which have relatively high chassis, hanging the second mounting module 22 under the first mounting module 21 not only ensures a compact layout but also provides a cover for the second mounting module 22 from rain and sun, providing safety protection. The first mounting module 21 and the second mounting module 22 can be of the same size, and can be interchanged with minor modifications, further reducing manufacturing costs.

[0050] As needed, a second installation module 22 can be set under multiple adjacent first installation modules 21; or multiple second installation modules 22 can be set under one first installation module 21.

[0051] refer to Figure 7As shown, in one embodiment, both the first mounting module 21 and the second mounting module 22 are configured as a housing structure with a built-in battery 5. This housing structure includes components configured as a reference... Figure 10 The cube frame structure shown includes the frame body and the deformable body formed by local modifications to the frame body. The shape of the deformable body can be referenced. Figure 8 and Figure 9 As shown. Among them, Figure 8 The cubic frame structure shown is Figure 10 The frame body shown has a deformable body formed by a slider on one outer surface. Figure 9 The cubic frame structure shown is Figure 10 The frame body shown has a slider on one outer surface and another deformable body formed by a track on the opposite outer surface. Figure 7 In the illustrated embodiment, the first mounting module 21 has four first sliders 211 disposed on the outer surface of one side of the frame body for sliding connection with two first suspension rails 112 in the first mounting compartment 11; two of the four first sliders 211 and one of the two first suspension rails 112 form a first sliding pair as described above. The second suspension rail 212 can be fixed to the frame body of the first mounting module 21 by welding or assembly.

[0052] The second mounting module 22 and the third mounting module 23 can be configured to have the same structure, but can vary in size ratio.

[0053] Optionally, the two ends of the first suspension track 112 are fixed to the base frame 1 using the first fixing seat 113, and the first suspension track 112 and the first fixing seat 113 are located inside the first installation chamber 11. The first suspension track 112 and the first fixing seat 113 can be assembled or welded together. The first fixing seat 113 can be made of a U-shaped bent plate or a square steel plate.

[0054] In the chassis of this application, in order to reduce the difficulty of installation and increase the installation speed, the chassis includes a slip enhancement component t, which includes a rolling element t3. The rolling element t3 is mounted on one of two sliding elements that slide against each other and rolls in contact with the other one.

[0055] refer to Figures 1-3 , Figures 15-18 In one embodiment shown, the slip-enhancing component t is disposed in the first sliding pair, wherein the rolling element t3 is mounted on the first slider 211 and rolls in contact with the first suspension rail 112. (Continuing to refer to...) Figure 15-18As shown in the figure, the first slider 211 includes two parallel flat plates, and a vertical plate is perpendicularly connected between the two flat plates. The two sides of the vertical plate and the two flat plates define two open slots with opposite openings, so that the cross-section of the vertical plate and the two flat plates is like the Chinese character '工' (worker). The first suspension rail 112 has an open slot, and the cross-section of the open slot is a 'T'-shaped slot like the Chinese character 'T'. One of the two flat plates of the first slider 211 is accommodated in the 'T'-shaped slot, and the other is located outside the 'T'-shaped slot; a through hole with a constriction is provided on the flat plate located in the 'T'-shaped slot, and a rolling element t3 is arranged in the through hole and is in rolling contact with the first suspension rail 112. Among them, the first slider 211 can be made of I-beam steel, the first suspension rail 112 can be made of C-channel steel, or it can also be formed by bending a steel plate, or it can be welded or assembled from steel materials.

[0056] Furthermore, in order to adjust the position of the rolling element t3, a stud t1 is also provided in the through hole. The stud t1 is located on the side of the rolling element t3 away from the contact surface between the first slider 211 and the first suspension rail 112, and the stud t1 abuts against the rolling element t3. By adjusting the screwing depth of the stud t1, the contact area between the rolling element t3 and the constriction can be adjusted, and thus the rolling friction force of the rolling element t3 can be adjusted, and further the rolling smoothness of the rolling element t3 can be adjusted.

[0057] In another embodiment, refer to Figure 18 As shown in the figure, a buffer member t2 is provided between the stud t1 and the rolling element t3. In order to make the rolling of the rolling element t3 smoother, a concave pit matching the outer shape of the rolling element t3 is provided in the buffer member t2, and one side of the rolling element t3 abuts against the inner wall of the concave pit. Of course, according to needs, the rolling element t3 can be a ball or a roller.

[0058] In another embodiment, refer to Figures 1-3 , Figures 15-18 , Figures 23-24 As shown in the figure, the second mounting module 22 and the first mounting module 21 are connected by a second sliding pair. The second sliding pair includes a second suspension rail 212 provided on the first mounting module 21 and a second slider 221 located on the second mounting module 22 and slidably connected to the second suspension rail 212. Among them, the second slider 221 can be made of I-beam steel, the second suspension rail 212 can be made of C-channel steel, or it can also be formed by bending a steel plate, or it can be welded or assembled from steel materials.

[0059] Refer to Figure 1 , Figure 24-25 , Figures 15-18 As shown in the figure, a lubrication enhancing component t can also be provided in the second sliding pair to reduce the installation resistance of the second mounting module 22.

[0060] In one embodiment, the cross-section of the second suspension track 212 is the same as that of the first suspension track 112, and the first slider 211 and the second slider 221 adopt the same structure. The installation method of the rolling element t3 in the second slider 221 is the same as that in the first slider 211. The cross-sections of the second suspension track 212 and the first suspension track 112 are completely identical. Since the base frame 1 is provided with stiffening plate B8 and middle plate B7, the second suspension track 212 can also be divided into multiple segments as needed to avoid stiffening plate B8 and / or middle plate B7.

[0061] In another embodiment, reference Figures 1-8 As shown, each first installation compartment 11 is provided with two parallel first suspension rails 112, and each first suspension rail 112 cooperates with two first sliders 211 on the first installation module 21.

[0062] In another embodiment, the chassis includes a second mounting compartment 12, which is arranged longitudinally with the first mounting compartment 11 along the base frame 1. The entrance / exit of the second mounting compartment 12 is located on the side of the base frame 1. The chassis includes a third mounting module 23, which enters from the entrance / exit of the second mounting compartment 12 and is slidably installed in the second mounting compartment 12 through a third sliding joint. The third sliding joint may also be provided with the aforementioned slip-enhancing component t, the structure and arrangement of which can be the same as described above.

[0063] In this application, the first sliding joint, the second sliding joint, and the third sliding joint can be adopted... Figure 13 The structure shown can also be replaced with an alternative structure. The first sliding joint, the second sliding joint, and the third sliding joint can use the same structure, or they can each use different structures.

[0064] Figure 13 Taking the third slider 231 and the second suspension track 212 as examples, the second suspension track 212 also adopts the same structure with a "T"-shaped groove as the first suspension track 112. ； The third slider 231 adopts an "I"-shaped structure formed by two flat plates connected by a vertical plate. One of the two flat plates of the third slider 231 is accommodated in the aforementioned "T"-shaped groove, and the other is fixed to the frame body of the second mounting module 22.

[0065] The cross-sectional shape of the first suspension track 112 and the second suspension track 212 can be square. Figure 19Taking the third slider 231 and the second suspension track 212 as examples in this alternative structure, the second suspension track 212 includes two parallel side plates, with a connecting plate perpendicularly connecting them on the same side. The two side plates and the connecting plate together define a first groove with a rectangular cross-section. The third slider 231 also includes two parallel side plates, with a connecting plate perpendicularly connecting them on the same side. The three together define a second groove with a rectangular cross-section. The first and second grooves are horizontally engaged with their openings facing each other. (Reference) Figure 20 As shown, in this alternative structure, the first slider 211, the second slider 221, and the third slider 231 can also adopt the threaded adjustment assembly 0123.

[0066] To further understand the structure of the threaded adjustment assembly 0123, please refer to... Figure 21-23 As shown, the threaded adjustment assembly 0123 includes a first screw 01231, a bushing 01232, a buffer pad 01233, a first nut 01234, and a ring 01235. The first screw 01231 is detachably mounted on the frame body. The ring 01235 is fitted around the outer circumference of the first screw 01231 and close to the screw head. The bushing 01232 abuts against the ring 01235 and the frame body. By adjusting the tightness of the first nut 01234, the tightness between the ring 01235 and the bushing 01232 can be controlled, thereby changing the rotation of the ring 01235 within the T-slot and achieving a smoothing effect.

[0067] In another embodiment, reference Figure 6 As shown, the base frame 1 is provided with two first mounting chambers 11 and two second mounting chambers 12. The two first mounting chambers 11 are symmetrically arranged along the longitudinal centerline of the base frame 1, and / or the two second mounting chambers 12 are symmetrically arranged along the longitudinal centerline of the base frame 1. In this embodiment, the slip enhancement component t can be provided in any one or more sliding pairs, and the rolling element t3 is mounted on one of the two sliding elements of the sliding pair and rolls in contact with the other. For example: in one case, the slip enhancement component t is only provided in the first sliding pair, and the rolling element t3 is mounted on one of the two sliding elements of the first sliding pair and rolls in contact with the other; in another case, the slip enhancement component t is only provided in the third sliding pair, and the rolling element t3 is mounted on one of the two sliding elements of the third sliding pair and rolls in contact with the other; in yet another case, multiple slip enhancement components t are respectively provided in the first sliding pair and the third sliding pair.

[0068] In another embodiment, reference Figures 1-6As shown, the chassis 1 includes a front support A, a middle support B, and a rear support C arranged longitudinally along the chassis 1. The front support A supports the driver's cab 3, the rear support C supports the upper vehicle, and the middle support B is located between the front support A and the rear support C. A first mounting compartment 11 and a second mounting compartment 12 are both located in the middle support B, and a mounting through hole 111 is formed in the middle support B. The second mounting compartment 12 is located between the rear support C and the first mounting compartment 11. This structure facilitates the installation and removal of the battery 5. Furthermore, the front support A, middle support B, and rear support C are integrated, and the chassis 1 provides protection for the battery 5 without the need for an additional battery protection cover. This reduces the weight of the chassis, optimizes the overall structure of the chassis 1, and makes it easier to arrange other components.

[0069] When the new energy equipment is a large-tonnage truck crane, the longitudinal length of the central support section B will be longer, allowing for the installation of more batteries. For example, when the tonnage is large, the central support section B can be lengthened, and more first mounting compartments 11 and / or second mounting compartments 12 can be set longitudinally at the central support section B to install more batteries 5.

[0070] In another embodiment, the middle support part B includes a rectangular box surrounded by an upper cover plate B1, a lower cover plate B2, a left side plate B3 and a right side plate B4 connecting the upper cover plate B1 and the lower cover plate B2, and a front side plate B5 and a rear side plate B6 disposed at the front and rear ends of the upper cover plate B1 and the lower cover plate B2, and a mounting through hole 111 is formed on the lower cover plate B2.

Rib plates B8 are provided on both sides of the central plate B7 along the transverse direction of the base frame 1. (Refer to...) Figure 1 , Figure 5 , Figure 7 As shown. In this embodiment, the second mounting module 22 is slidably connected to the second suspension rail 212 on the first mounting module 21 via its own second slider 221 through the mounting through hole 111. Since two mounting through holes 111 are provided below each first mounting compartment 11, the second suspension rail 212 is configured as a multi-segment structure. Reference Figure 24As shown, each second suspension rail 212 includes a first half-rail 2121 and a second half-rail 2122 arranged laterally. When installing the second mounting module 22, two second sliders 221 on the second mounting module 22, corresponding to each second suspension rail 212, enter the first mounting chamber 11 from two mounting through holes 111 below the same first mounting chamber 11 and then slide to connect with the first mounting module 21. In this embodiment, to prevent the second mounting module 22 from slipping, a stop third limiting component 213 is provided on the same side of the first half-rail 2121 and the second half-rail 2122. The third limiting component 213 can be a detachable threaded component. By setting the third limiting component 213, on the one hand, the second mounting module 22 can be prevented from slipping; on the other hand, it can also quickly position the second mounting module 22 during installation.

Figure 12 As shown, the first limiting component 114 adopts a threaded structure and is located at the inner end of the first suspension track 112 away from the entrance and exit of the first installation chamber 11. The first limiting component 114 is installed before the first installation module 21 is installed. The second limiting component 115 includes a first limiting plate 1151 and a first fixing plate 1152. The first limiting plate 1151 and the first fixing plate 1152 are installed after the first installation module 21 is installed into the first installation chamber 11. The first limiting plate 1151, the first fixing plate 1152 and the first limiting component 114 work together to fix the first installation module 21 on the base frame 1.

[0082] In another embodiment, reference Figure 24As shown, the second suspension track 212 adopts a multi-segment structure. The second suspension track 212 includes a first half-rail 2121 and a second half-rail 2122. The limiting mechanism includes a fourth limiting component 214 and a third limiting component 213 disposed on the same side of the first half-rail 2121 and the second half-rail 2122.

[0083] Among them, reference Figure 24 As shown, the third limiting component 213 all adopts a threaded component.

[0084] refer to Figures 11-14 As shown, the fourth limiting component 214 includes a second limiting plate 2141 and a second fixing plate 2142. Both the second limiting plate 2141 and the second fixing plate 2142 are configured as L-shaped plates composed of two mutually perpendicular flat plates. The second limiting plate 2141 and the second fixing plate 2142 are arranged such that the intersection line of the two flat plates of the second limiting plate 2141 is perpendicular to the intersection line of the two flat plates of the second fixing plate 2142. The fourth limiting component 214 and the third limiting component 213 work together to fix the second mounting module 22 to the first mounting module 21.

[0085] In another embodiment, the third mounting module 23 is provided with a fifth limiting component and a sixth limiting component. The fifth limiting component is a threaded component, and the sixth limiting component has the same structure as the fourth limiting component 214. The fifth limiting component and the sixth limiting component work together to fix the fourth mounting module 24 in the second mounting chamber 12.

[0086] In another embodiment, a turntable 4 for connecting to the upper vehicle is provided on the rear support C.

[0087] In this application, the chassis can be either wheel-driven or track-driven.

[0088] To further illustrate this application, the installation of the first mounting module 21, the second mounting module 22, the third mounting module 23, and the fourth mounting module 24 in the chassis of one embodiment will be briefly described below.

[0089] 1. Fix the battery 5 to the frame body to form a basic module; 2. Depending on the different installation positions on the base frame 1, make appropriate modifications to the frame body to form a deformable body, and fix the battery 5 in the deformable body to form an extended module; 3. Install the basic module and the extended module at different positions on the base frame 1 as needed.

[0090] like Figure 7 As shown, the fourth mounting module 24 is the basic module, and the first mounting module 21, the second mounting module 22 and the third mounting module 23 are several extension modules provided in the embodiments of this application.

[0091] For reference Figure 1As shown, the base frame 1 includes a front support part A, a middle support part B, and a rear support part C; the middle support part B is provided with two first mounting compartments 11 symmetrically arranged along the longitudinal center line of the base frame 1 and two second mounting compartments 12 symmetrically arranged along the longitudinal center line of the base frame 1; a battery mounting bracket 13 is provided at the connection between the middle support part B and the front support part A, and two fourth mounting modules 24 are fixed on the battery mounting bracket 13.

[0092] Firstly, the installation of the fourth mounting module 24: the two fourth mounting modules 24 can be fixed to the battery mounting bracket 13 using bolts.

[0093] Secondly, the installation of the first installation module 21: A first suspension rail 112 is set in the first installation chamber 11. The inner end of the first suspension rail 112 is set with a first limiting component 114 with threaded limit. The first installation module 21 enters from the entrance and exit of the first installation chamber 11. When the first slider 211 on the first installation module 21 and the first suspension rail 112 enter the working position of mutual engagement, the first installation module 21 can be pushed into the first installation chamber 11. Finally, the second limiting component 115 is used to fix the relative position of the first installation module 21 and the first suspension rail 112 to prevent the first installation module 21 from shaking when the new energy equipment is running or operating. The short guide rail below the first installation module 21, i.e. the second suspension rail 212, can be used to hang the second installation module 22.

[0094] Thirdly, the installation of the third mounting module 23: The installation of the third mounting module 23 is similar to that of the first mounting module 21, and will not be described in detail here.

[0095] Fourthly, the installation of the second mounting module 22 differs slightly from the installation of other mounting modules: First, move the second mounting module 22 to a suitable position below the first mounting module 21; then lift the second mounting module 22 so that the second slider 221 on it passes through the mounting through hole 111; then align the second slider 221 with the second suspension rail 212 at the bottom of the first mounting module 21 and connect them; this allows the second slider 221 and the second suspension rail 212 to engage and slide relative to each other. (Refer to...) Figure 24 , Figure 11 and Figure 12 As shown, after the second installation module 22 and the third limiting component 213 come into contact with the limiting position, the installation is completed by fixing through the fourth limiting component 214.

[0096] When subsequent repairs or disassembly of the various installation modules are required, simply follow the reverse installation steps to quickly replace the battery 5.

[0097] Secondly, this application provides a new energy device, including the aforementioned chassis. This new energy device possesses the technical advantages of the aforementioned chassis, which will not be elaborated further here.

[0098] The new energy equipment includes a vehicle, which is connected to the chassis via a turntable 4.

[0099] The new energy equipment includes a driver's cab 3 installed on the front support A, and the driver's cab 3 and the chassis form a vehicle.

[0100] In another embodiment, the upper vehicle includes a boom, the base of which is connected to a turntable 4.

[0101] In another embodiment, a working mechanism is connected to the end of the boom away from the rotary table 4. This working mechanism can be used to perform various tasks, for example: the working mechanism can be a lifting device for lifting heavy objects; the working mechanism can also be a work platform for lifting people and / or objects; the working mechanism can also be a bucket for digging operations.

[0102] It should be understood that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. A and B can be singular or plural.
