[0065] At present, the energy parts of conventional vehicles are mostly scattered. According to the actual conditions of different models, these energy components will be distributed in different parts of the vehicle, which is relatively scattered. The advantage is that it is relatively flexible, but there are also some disadvantages. In addition to the energy part, the vehicle's electrical system with control unit and rear travel unit are also distributed on different frame modules of the vehicle. This will cause more or less overlap in production, transportation and management, which will affect efficiency and increase costs. Especially for new energy vehicles, since new energy has just developed and is not very mature, it is usually manifested in unreasonable layout, scattered parts, repeated and complicated pipe connections, and inconvenient installation.

[0066] The embodiment of the present application provides a vehicle rear frame module, which can be used for new energy vehicles, and of course, can also be used for traditional oil vehicles. The vehicle rear frame module integrates the relevant parts of the energy part to form an energy module 200, and also integrates the parts of the vehicle body to a great extent, integrating the energy module 200, the electrical system 300 and the rear travel unit 400 into the rear frame 100. The parts are arranged concisely and compactly, and the functions are complete and independent, which can improve the overall production efficiency and reduce costs. Of course, it is not limited to the above-mentioned integrated parts, and other chassis and electrical parts can also be integrated as needed.

[0067] The following will be combined Figures 1 to 15 A vehicle rear frame module and a vehicle provided in an embodiment of the utility model are introduced.

[0068] like Figure 1 , Figure 2 and Figure 3 As shown, a first aspect of the present invention provides a vehicle rear frame module, which includes a rear frame 100, an energy module 200 and an electrical system 300.

[0069] like Figure 2 and Figure 4As shown, the rear frame 100 is a frame structure. The middle part of the rear frame 100 has an energy module installation position 120, the rear part of the rear frame 100 has a rear travel unit installation position 140 for connecting with the rear travel unit 400, and the rear frame 100 is also provided with an electrical system installation position 150. The energy module installation position 120 has a lateral opening 122, and the energy module 200 can be installed on the energy module installation position 120 through the lateral opening 122. The electrical system 300 is installed on the electrical system installation position 150 and is electrically connected to the energy module 200.

[0070] The vehicle rear frame module provided by the embodiment of this aspect has a rear travel unit installation position 140, an energy module installation position 120 and an electrical system installation position 150, which are respectively connected to the rear travel unit 400, the energy module 200 and the electrical system 300. These three modules are integrated into the rear frame 100 of the vehicle and connected to different installation positions. The parts are arranged concisely and compactly, the functions are complete and independent, and the installation is convenient, which can improve the production efficiency of the vehicle and reduce the cost. In addition, the rear frame 100 is a frame structure, which has good structural strength and is not easy to deform compared with a flat plate structure.

[0071] Furthermore, in some embodiments, the rear frame 100 is a frame structure with a set height and has an installation space inside to conveniently accommodate some parts of the vehicle.

[0072] For example, the rear frame 100 includes a plurality of longitudinal beams, each of which extends integrally along the front-rear direction of the vehicle rear frame module. The plurality of longitudinal beams are arranged in two rows in the height direction, with an installation space between them. For another example, the rear frame 100 also includes a plurality of vertical beams, which are connected to form two rows of longitudinal beams to support the installation space. For another example, the rear frame 100 may also include a plurality of cross beams, which connect the plurality of longitudinal beams to improve the overall connection stability of the rear frame 100.

[0073] Furthermore, in some embodiments, Figure 2 and Figure 3 As shown, the energy module 200 and / or the electrical system 300 are arranged inside the rear frame 100, such as in the above-mentioned installation space. The overall structure of the vehicle rear frame module is compact, and the rear frame 100 can also provide protection for the energy module 200 and / or the electrical system 300. Even if a collision occurs, the rear frame 100 will be impacted first, thereby reducing the impact on the energy module 200 and / or the electrical system 300, and reducing the probability of damage to the energy module 200 and the electrical system 300 due to the collision, or even fire. Moreover, wiring can be done inside the rear frame 100, which is safe.

[0074] In addition, if the energy module 200 is disposed inside the rear frame 100 and the energy module installation position 120 has a lateral opening 122, the energy module 200 can be placed into the rear frame 100 or taken out from the rear frame 100 from the side without interfering with the components above the rear frame 100, and there is no need to leave an avoidance space above the rear frame 100 for taking and placing the energy module 200, which provides convenience for arranging components such as the car body above the rear frame 100.

The energy module installation position 120 is formed between the upper longitudinal beam 111 and the lower longitudinal beam 113, and the lateral opening 122 is located between the upper longitudinal beam 111 and the lower longitudinal beam 113.

[0076] In these embodiments, a certain installation space can be formed between the two upper longitudinal beams 111 and the two lower longitudinal beams 113, and the energy module 200 is installed in the installation space between the upper longitudinal beams 111 and the lower longitudinal beams 113. On the one hand, the structure is compact, and on the other hand, the two upper longitudinal beams 111 and the two lower longitudinal beams 113 can protect the energy module 200. When a collision occurs on the side of the vehicle, the upper longitudinal beams 111 and the lower longitudinal beams 113 can block the impact force from being transmitted to the energy module 200, thereby reducing the probability of the energy module 200 being damaged or even catching fire due to a strong impact. In addition, referring to Figure 2 A lateral opening 122 is provided between the upper longitudinal beam 111 and the lower longitudinal beam 113, so that the energy module 200 can be placed into or taken out of the installation space through the lateral opening 122. The lateral placement is convenient for operation. For example, the energy module 200 can be pulled out horizontally, which saves effort. Moreover, the placement and removal of the energy module 200 will not interfere with the components above the rear frame 100.

[0077] In addition, the rear frame 100 includes two upper longitudinal beams 111 and two lower longitudinal beams 113. The rear frame 100 occupies a certain height. This frame-type structure is convenient for accommodating parts inside. Compared with a flat frame, even if it is impacted, it is not easy to bend and deform greatly and become scrapped as a whole. It has good safety and saves maintenance costs. Of course, the number of the upper longitudinal beams 111 and the lower longitudinal beams 113 is not limited to two, and can also be three or even more than three.

[0078] Regarding the specific structure of the energy module installation position 120, further, in some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the energy module installation position 120 includes a plurality of installation holes 121 arranged on the upper surface of the middle part of the two lower longitudinal beams 113; the vehicle rear frame module also includes a plurality of first bolts 230, and the plurality of first bolts 230 pass through the energy module 200 and are inserted into the plurality of installation holes 121. Here, the energy module 200 is installed on the upper surface of the lower longitudinal beam 113, and the energy module 200 can be located in the space between the upper longitudinal beam 111 and the lower longitudinal beam 113, and the rear frame 100 can protect the energy module 200. Moreover, the energy module 200 is fixed to the lower longitudinal beam 113 by the first bolts 230, which has a simple structure and is firmly installed.

[0079] Regarding the specific structure of the energy module 200, further, in some embodiments, such as Figure 7 As shown, the energy module 200 includes a battery pack unit, the battery pack unit includes a battery holder 210 and a battery 220 mounted on the battery holder 210, and the battery holder 210 is connected to the energy module mounting position 120. Here, the battery holder 210 is used to support and limit the battery 220, and the battery holder 210 is connected to the energy module mounting position 120, so there is no need to set a connection structure on the battery 220, which simplifies the structure of the battery 220.

[0080] Furthermore, the battery 220 is detachably mounted on the battery holder 210 , so that the battery 220 can be replaced conveniently.

[0081] Furthermore, if Figure 7 , Figure 8 and Fig. 9 As shown, one of the battery holder 210 and the battery 220 is provided with a guide groove 211 extending along the width direction of the vehicle rear frame module, and the other is provided with a guide rail 221 extending along the width direction of the vehicle rear frame module, and the guide rail 221 and the guide groove 211 cooperate with each other to guide the battery 220 to be installed in the battery holder 210, or to guide the battery 220 to be removed from the battery holder 210. It is convenient for the battery 220 to be quickly installed in place, and the cooperation of the guide groove 211 and the guide rail 221 can also limit the battery 220, preventing the battery 220 from moving in the length direction of the vehicle rear frame module.

The battery holder 210 has openings 212 on both sides facing the width direction of the rear frame module of the vehicle, which facilitates the battery 220 to be placed in the battery holder 210 from the openings 212 in the width direction of the rear frame module of the vehicle. A guide limit block 213 is arranged on the lower surface of the top wall of the battery holder 210, and the guide limit block 213 can prevent the battery 220 from moving upward significantly. The guide slope 214 is used to guide the battery 220 into the battery fixing seat 210 , so as to avoid interference between the battery 220 and the guide limit block 213 during the assembly process, thereby facilitating the installation of the battery 220 .

[0083] Further, after the battery 220 is installed on the battery holder 210, refer to Fig. 9 The second bolt 240 is used to connect the battery 220 and the battery fixing seat 210. This can prevent the battery 220 from easily detaching from the battery fixing seat 210, and the two are bolted together for easy disassembly.

[0084] In addition, reference Figure 6 The energy module 200 may include a plurality of battery pack units, and the plurality of battery pack units are adjacently arranged in the front-rear direction of the rear frame 100. The plurality of battery pack units are integrated together, which can reduce the power supply lines and facilitate the unified installation or replacement of the battery 220.

[0085] Regarding the specific structure of the rear travel unit installation position 140 and the specific structure of the rear travel unit 400, further, in some embodiments, such as Figure 4 , Figure 6 , Fig.13 , Fig.14 and Fig.15 As shown, a shock absorber mounting bracket 141 and a trailing arm mounting bracket 142 are provided in the rear travel unit mounting position 140. The vehicle rear frame module further includes a rear travel unit 400, which includes two rear wheels 410, a rear suspension 420 connecting the two rear wheels 410, two shock absorbers 430 connected to the rear suspension 420, and two trailing arms 440 connected to the rear suspension 420 and extending forward, the ends of the two shock absorbers 430 are connected to the shock absorber mounting bracket 141, and the ends of the two trailing arms 440 are connected to the trailing arm mounting bracket 142.

[0086] In these embodiments, the rear frame 100 is provided with both a shock absorber mounting bracket 141 and a trailing arm mounting bracket 142, which are respectively connected to the shock absorber 430 and the trailing arm 440 of the rear traveling unit 400, thereby ensuring that the rear frame 100 and the rear traveling unit 400 are stably connected together.

[0087] Furthermore, if Fig.13 and Fig.15 As shown, the rear travel unit 400 further includes a handbrake system 450, and the rear travel unit mounting position 140 further includes a handbrake mounting bracket 143 disposed on one of the longitudinal beams, and a handbrake member 451 of the handbrake system 450 is mounted on the handbrake mounting bracket 143. Here, the handbrake mounting bracket 143 is also integrated on the rear frame 100, and the structure is compact.

[0088] As an example, refer to Fig.15 The handbrake mounting bracket 143 is disposed on one of the upper longitudinal beams 111 , so as to facilitate the driver to hold the handbrake system 450 to control the rear travel unit 400 .

[0089] As an example, the handbrake mounting bracket 143 is fixed to one of the upper longitudinal beams 111 by bolts.

[0090] like Fig.15 As shown, the handbrake system 450 further includes a brake disc 452 and a control line 453, the brake disc 452 is used in conjunction with the rear wheel 410, the control line 453 connects the brake disc 452 and the handbrake member 451, and the upper longitudinal beam 111 where the handbrake mounting bracket 143 is located may also have a control line limit buckle 144, the control line 453 extends along the upper longitudinal beam 111 and is limited to the control line limit buckle 144. The line distribution is reasonable and will not run around.

[0091] Furthermore, if Fig.14 and Fig.15 As shown, the rear frame 100 further includes a plurality of upper cross beams 112, at least one lower cross beam 114, two front vertical beams 115 and two rear vertical beams 116. The plurality of upper cross beams 112 are connected to the upper longitudinal beams 111 along the width direction of the rear frame module of the vehicle; at least one lower cross beam 114 is connected to the lower longitudinal beams 113 along the width direction of the rear frame module of the vehicle; the two front vertical beams 115 are connected to the front ends of the two upper longitudinal beams 111 and the front ends of the two lower longitudinal beams 113 respectively; the two rear vertical beams 116 are connected to the rear ends of the two upper longitudinal beams 111 and the two lower longitudinal beams 113, and the rear ends of the two upper longitudinal beams 111 exceed the two rear vertical beams 116, thereby forming an installation space for the rear travel unit 400 at the rear side of the rear frame 100.

[0092] The rear frame 100 can form a three-dimensional structure with an installation space inside through two upper longitudinal beams 111, two lower longitudinal beams 113, multiple upper cross beams 112, at least one lower cross beam 114, two front vertical beams 115 and two rear vertical beams 116, so that it is convenient to use the installation space to accommodate components, such as energy modules 200, electrical systems 300, etc., and the components in the installation space can be protected in multiple directions, which is safe. In addition, the rear ends of the two upper longitudinal beams 111 are extended beyond the two rear vertical beams 116 and extend backwards for a certain distance, so that the overall length of the rear frame 100 can be increased, so that the rear frame 100 can be convenient to carry longer containers or more seats.

[0093] Furthermore, the two upper longitudinal beams 111 can be extended backward beyond the rear traveling unit 400, and the rear ends of the two upper longitudinal beams 111 exceed the rear traveling unit 400. In this way, even if a collision occurs at the rear side of the vehicle, the two upper longitudinal beams 111 will be impacted first, or the upper cross beam 112 connecting the rear ends of the two upper longitudinal beams 111 will be impacted, thereby protecting the rear traveling unit 400.

[0094] Furthermore, the upper longitudinal beam 111 and the front vertical beam 115 can be an integrated structure, which is convenient for processing and the two are firmly connected.

[0095] Regarding the specific structure of the electrical system installation position 150 and the specific structure of the electrical system 300, further, in some embodiments, as Figure 1 , Figure 2 and Fig.12 As shown, the electrical system 300 includes a control unit 310 and a main wiring harness 320 connected to the control unit 310. The electrical system mounting position 150 includes a control unit mounting position 151 and a wiring harness mounting position 152. The control unit mounting position 151 is arranged at the rear side of the energy module mounting position 120. The wiring harness mounting position 152 extends along one of the longitudinal beams. The control unit 310 is installed at the control unit mounting position 151, and the main wiring harness 320 is installed at the wiring harness mounting position 152.

[0096] In these embodiments, the control unit 310 is arranged at the rear side of the energy module 200, so that the control unit 310 is conveniently electrically connected to the energy module 200, so that the control unit 310 is powered by the energy module 200. The wiring harness installation position 152 is extended along one of the longitudinal beams, and the main wiring harness 320 is extended along the lower longitudinal beam 113. Limited by the wiring harness installation position 152 and the longitudinal beam, the main wiring harness 320 will not be scattered around in the rear frame 100, and the layout is simple. In addition, it is convenient for the main wiring harness 320 to extend forward along the longitudinal beam to connect with the control module in the cab of the vehicle.

[0097] Regarding the specific structure and setting position of the wiring harness installation position 152, further, in some embodiments, such as Figure 1As shown, the harness installation position 152 may include a harness stop buckle 153 disposed on the lower longitudinal beam 113, and the harness stop buckle 153 is used to stop the main harness 320. There are multiple harness stop buckles 153, which are spaced apart along one of the lower longitudinal beams 113.

[0098] As an example, the wire harness limiting buckle 153 may include a plug-in portion and a wire harness sleeve connected to the plug-in portion, the plug-in portion is inserted into the mounting hole 121 of the lower longitudinal beam 113, and the wire harness sleeve is sleeved on the outer periphery of the main wire harness 320 to limit the main wire harness 320 on the lower longitudinal beam 113.

[0099] As an example, the harness limiting buckle 153 may also include an elastic buckle fixed on the lower longitudinal beam 113, and the elastic buckle and the lower longitudinal beam 113 enclose a storage space for accommodating the main harness 320, and one end of the elastic buckle is a free end, which can be opened and closed to expand or reduce the storage space. When installing the main harness 320, move the elastic buckle to open its free end, squeeze the main harness 320 from the gap between the free end of the elastic buckle and the lower longitudinal beam 113 into the storage space, and then close the elastic buckle under its own elastic force, and the elastic buckle limits the main harness 320 in the storage space.

[0100] Of course, the wire harness limiting buckle 153 may also be a binding belt, one end of which has a limiting buckle that can limit the other end from detaching, and the binding belt binds the main wire harness 320 and the lower longitudinal beam 113 together.

[0101] In addition, the electrical system 300 may further include a branch harness connected to the control unit 310. The branch harness may extend along other beams of the rear frame 100, such as along the upper cross beam 112 of the rear frame 100, and fit the rear frame 100 as closely as possible to avoid harness disorder.

[0102] Regarding the specific structure and setting position of the control unit installation position 151, further, in some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the rear frame 100 further includes two rear vertical beams 116 and at least one lower cross beam 114. The two rear vertical beams 116 connect the rear ends of the two upper longitudinal beams 111 and the two lower longitudinal beams 113, and the rear ends of the two upper longitudinal beams 111 exceed the two rear vertical beams 116, so as to form a rear travel unit 400 installation space at the rear side of the rear frame 100; at least one lower cross beam 114 connects the lower longitudinal beams 113 along the width direction of the vehicle rear frame module, and at least one lower cross beam 114 includes a first lower cross beam 1141, and the first lower cross beam 1141 is arranged near the two rear vertical beams 116. The control unit installation position 151 includes a control unit 310 bracket connected to the first lower cross beam 1141, and the control unit 310 is arranged on the control unit 310 bracket.

[0103] Here, the rear ends of the two upper longitudinal beams 111 are made to extend beyond the two rear vertical beams 116, and the rear travel unit 400 is installed below the extended portion of the two upper longitudinal beams 111, so as to separate the rear travel unit 400 from the space above the rear frame 100. The extended portion of the two upper longitudinal beams 111 can protect the rear travel unit 400, and can reduce the probability of objects above the rear frame 100 falling and hitting the rear travel unit 400 during the driving of the vehicle. Moreover, the two upper longitudinal beams 111 extend backward beyond the two rear vertical beams 116, and can also increase the overall length of the rear frame 100, so as to facilitate the rear frame 100 to carry longer containers or more seats.

[0104] In addition, at least one lower cross beam 114 is used to connect the lower longitudinal beam 113, wherein the first lower cross beam 1141 is arranged close to the two rear vertical beams 116, which can improve the overall structural strength of the rear frame 100. The control unit 310 bracket is arranged on the first lower cross beam 1141, which is convenient for installation, and there is no need to configure an additional connecting plate to support the control unit 310 bracket, thereby simplifying the structure.

[0105] Furthermore, since the first lower cross beam 1141 is disposed close to the two rear vertical beams 116, the control unit 310 bracket can be connected to an adjacent rear vertical beam 116 in addition to being connected to the first lower cross beam 1141. Then, the control unit 310 bracket, the rear vertical beam 116 and the first lower cross beam 1141 can be connected to each other in pairs at three points, and the control unit 310 bracket has good installation stability, and can improve the connection stability of the rear frame 100.

[0106] As an example, the control unit 310 bracket is in the shape of a rod, obliquely connecting a rear vertical beam 116 and a first lower cross beam 1141. Figure 4 The rear frame 100 may further include a support rod 117, which is relatively distributed with the support rod 117 and the support rod 310 in the width direction of the rear frame module of the vehicle, and obliquely connects another rear vertical beam 116 and the first lower cross beam 1141. The support rod 117 and the support rod 117 are symmetrically distributed on the left and right sides, thereby improving the connection stability of the rear frame 100.

[0107] Furthermore, in some embodiments, Figure 3 , Figure 4 , Figure 5 and Fig.11 As shown, the vehicle rear frame module further includes a charging unit 500 . A charging installation position 130 is provided on one side of the rear frame 100 .

Each front vertical beam 115 corresponds to connecting the front end of an upper longitudinal beam 111 and the front end of a lower longitudinal beam 113. Each rear vertical beam 116 corresponds to connecting the middle and rear part of an upper longitudinal beam 111 and the rear end of a lower longitudinal beam 113. The four upper cross beams 112 are respectively a first upper cross beam 1121, a second upper cross beam 1122, a third upper cross beam 1123 and a fourth upper cross beam 1124.

The battery 220 is a complete and independent whole in the shape of a rectangular parallelepiped. The lower part of the battery 220 has two protruding guide rails 221 that cooperate with the guide grooves 211 on the battery holder 210. The battery 220 is Fig.10 Taking the middle direction as the reference, when the battery holder 210 is pushed to the right, the guide rail 221 and the guide groove 211 cooperate, so that the battery 220 can enter the battery holder 210 along the guide groove 211. When the right end of the battery 220 enters the upper part of the battery holder 210, the guide slope 214 on the guide limit block 213 on the inner surface of the upper side of the battery holder 210 begins to work, allowing the battery 220 to enter smoothly and correct the position of the battery 220 to the correct state. Then the battery 220 is fixed to the battery holder 210 by the second bolt 240 to complete the installation and fixation of the battery 220. This example uses three battery 220 pack units to power the vehicle, which are fixed to the rear frame by the first bolt 230.
