DETAILED DESCRIPTION

[0090] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0091] Embodiment 1

[0092] See also Figures 1 to 9 As shown, the first embodiment of the present application provides a compartment roof assembly 1, comprising: a high area roof 11, a low area roof 12 and a transition roof 13. The high area roof 11 and the low area roof 12 are sequentially arranged along the length direction of the compartment 100, and an integrated air duct 1222 is arranged on the low area roof 12. The transition roof 13 is arranged between the high area roof 11 and the low area roof 12, and the transition roof 13 connects the high area roof 11 and the low area roof 12 respectively.

[0093] The roof panel assembly of the present application realizes the transition from the high area to the low area of ​​the roof panel of the car 100, meeting the aesthetic requirements of the passenger compartment area and the visual flexibility of the passengers. The embodiment of the present application arranges an integrated air duct 1222 on the low-area roof panel 12, and there is no need to arrange an independent large-volume air duct on the top of the low-area roof panel 12, thereby saving space and facilitating overall supply. It solves the problem that the air-conditioning duct is difficult to install in the case of a special low-top vehicle body, thereby improving the installation processability, reducing costs, and improving installation efficiency.

[0094] In some possible implementations, see Figure 2 As shown, the upper surface of the low-zone top plate 12 is provided with an integrated air duct 1222 and an upper guide tube 1223 connected to the integrated air duct 1222, and the upper guide tube 1223 is used to connect the main air duct in the compartment 100. The integrated air duct 1222 is designed with a predetermined path so that the upper guide tube 1223 can be successfully docked with the air duct arranged in the high-top area, and then plugged and fixed to complete the installation of the low-zone top plate. By integrating the air duct on the low-zone top plate 12, the problem of the difficulty of installing a separate air conditioning air duct in the case of a special low-top vehicle body is solved, achieving the effect of killing two birds with one stone.

[0095] In some possible implementations, see Figure 3 and Figure 4 As shown, the low area top plate 12 includes a middle top plate 121 and side top plates 122 located on both sides of the middle top plate 121, and plug-in beams 1211 are respectively provided on both sides of the middle top plate 121 along the width direction of the bus, and the side top plates 122 are plugged into the corresponding plug-in beams 1211, and lamp holes 1221 and integrated air ducts 1222 are provided on the side top plates 122.

[0096] The middle top plate 121 can be first fixed to the carriage body through the connection code and the transfer beam 15. After the plug-in beams 1211 on both sides of the middle top plate 121 are fixed to the transfer beam 15 by screws, the two side top plates 122 are respectively plugged into the corresponding plug-in beams 1211 on both sides of the middle top plate 121. The rectangular lamp holes pre-opened on the side top plates 122 provide a location for installing the lighting lamps, and an integrated air duct 1222 is set on the back, thereby realizing the overall supply. At the same time, the middle top plate 121 and the side top plates 122 adopt a plug-in matching structure, and there are no exposed installation fasteners at the connection parts, and the appearance of the visible area of ​​the passenger compartment is flat and beautiful.

[0097] In some possible implementations, see Figure 4 As shown, the plug-in beam 1211 includes a first beam portion 12111 and a second beam portion 12112, the first beam portion 12111 is connected to the side top plate 122, the second beam portion 12112 is connected to the first beam portion 12111, the second beam portion 12112 is used to be connected and fixed to the carriage 100, a slot 12113 is formed between the first beam portion 12111 and the second beam portion 12112, and the side top plate 122 is plugged into the slot 12113. The side top plate 122 is directly plugged into the slot 12113, and there is no need to use fasteners to connect the side top plate 122 and the middle top plate 121. The side top plate 122 and the middle top plate 121 overlap and cooperate, and there are no exposed installation fasteners, and the appearance of the visible area of ​​the passenger compartment is flat and beautiful.

[0098] In some possible implementations, see Figure 4 As shown, the middle top plate 121 is respectively provided with a first upturned portion 1212 on both side edges along the width direction of the car body 100, the first beam portion 12111 and the second beam portion 12112 are connected by a connecting beam portion, and the second upturned portion 12111a is provided at the end of the first beam portion 12111 away from the connecting beam, the first beam portion 12111 is provided on the upper surface of one side edge of the middle top plate 121 along the width direction of the car body 100, and the second upturned portion 12111a of the first beam portion 12111 is fitted and connected with the first upturned portion 1212.

[0099] The edge of the middle top plate 121 is provided with a first upturned portion 1212, which can limit the first beam portion 12111, and facilitate the rapid positioning and assembly of the first beam portion 12111 and the middle top plate 121. The edge of the middle top plate 121 is provided with a second upturned portion 12111a, which is attached to the upper surface of the first upturned portion 1212, and the two can be welded and fixed. The attachment surface of the first upturned portion 1212 and the second upturned portion 12111a is an arc surface, which increases the contact area between the first beam portion 12111 and the middle top plate 121, and enhances the connection structural strength of the main structure of the first beam portion 12111 and the middle top plate 121.

[0100] In some possible implementations, see Figure 4As shown, a protrusion 12112a is provided on the surface of the second beam portion 12112, and the protrusion 12112a protrudes toward the first beam portion 12111. When the side top plate 122 is inserted into the slot 12113, the protrusion 12112a is limited to the side of the side top plate 122 away from the first beam portion 12111.

[0101] The protrusion 12112a can be set to limit the top of the side top plate 122 when the side top plate 122 is inserted into the slot 12113. If the side top plate 122 is tilted, the protrusion 12112a will abut against the side top plate 122, supporting the side top plate 122, reducing the deformation of the side top plate 122, and preventing the side top plate 122 from being separated from the slot 12113. The protrusion 12112a extends toward the end of the first upturned portion 1212, reducing the gap between the two, thereby enhancing the limiting effect on the side top plate 122, making it difficult for the side top plate 122 to be pulled out of the plug-in beam 1211.

[0102] In some possible implementations, see Figure 5 and Figure 6 As shown, the high area top plate 11 includes a light strip 112 and two side plates 111 , a gap groove is formed between the two side plates 111 , the light strip 112 is respectively connected to the two side plates 111 , the light strip 112 extends along the gap groove, and the light strip 112 covers the gap groove.

[0103] The high area top plate 11 is divided into two parts on the left and right sides in the width of the vehicle body. The lower part of the side plate 111 is connected and fixed to the fixed beam of the vehicle body side wall 9. The fixed beam of the vehicle body side wall 9 is connected to the F line profile, and then the decorative plate d is fixed. In the embodiment of the present application, by setting the high area top plate 11 as two spaced side plates 111, the installation requirements of the light strip 112 are met, so that the light strip 112 can be arranged between the two. A fan and a decorative plate d can also be set on the side plate 111.

[0104] In some possible implementations, see Figure 6 As shown, a bent edge 1111 is provided on one side edge of the side plate 111 located at the gap groove, a full-length reinforcement 113 is provided on the side plate 111 , the full-length reinforcement 113 is located on the inner side of the bent edge 1111 , and the light strip 112 is fixed to the full-length reinforcement 113 by a fastener 173 .

[0105] The width of the bent edge 1111 can match the thickness of the full-length reinforcement. The full-length reinforcement 113 is arranged within 30mm of the plane of the side panel 111 from the bent edge 1111, which can be used for the installation of the full-length light strip 112. A rectangular opening can be pre-opened on the side panel 111 for the installation of the air outlet 14. The bent edge 1111 plays the role of limiting the full-length reinforcement, which facilitates the rapid assembly of the full-length reinforcement. By setting the bent edge 1111 on the edge of the side panel 111, the structural strength and rigidity of the side panel 111 can be further enhanced, and the deformation of the side panel 111 can be reduced. The full-length reinforcement 113 has a large thickness, and a connecting hole, such as a threaded hole, can be provided. The fastener 173 can be a bolt, and one end of the bolt can pass through the light strip 112 and be connected to the threaded hole, thereby completing the assembly and fixation of the light strip 112.

[0106] In some possible implementations, see Figure 6 As shown, a duct support beam c may be provided on the carriage 100 to support the duct provided on the top of the carriage 100. A connecting seat 114 is provided on one side of the gap groove of the side plate 111, and a fastener 115 is provided on the connecting seat 114. The fastener 115 is used for connection and fixing. A C-shaped groove may be provided in the connecting seat 114, and the fastener 115 is pre-installed on the C-shaped groove to facilitate fixing the side plate 111 to the duct support beam c.

[0107] In some possible implementations, see Figures 7 to 9 As shown, the transition top plate 13 includes a vertical plate 131 and a horizontal plate 132. The horizontal plate 132 is connected to the lower edge of the vertical plate 131. A plurality of connection codes a are provided on the vertical plate 131. The high area top plate 11 is connected to the vertical plate 131, and the low area top plate 12 is connected to the horizontal plate 132.

[0108] As the vehicle body moves toward both sides of the vehicle length direction, the height of the vehicle body section decreases, and the top plate transitions from a high top to a low top. The transition area between the high area top plate 11 and the low area top plate 12 is arranged as follows: Figure 7 The transition top plate 13 structure shown has an L-shaped cross-section, and three connecting codes a are set on the top of the vertical plate 131, which is fixed to the air duct support beam c through the connecting codes a. The lower part is designed with flanges on both sides in the vehicle width direction, and the flanges on both sides are fixed on the side walls 9, thus completing the installation of the transition top plate 13 structure itself.

[0109] A full-length reinforcing beam 133 may be added to the L-shaped bend of the transition top plate 13 to ensure the rigidity of the top plate. A full-length plug-in profile 1321 may also be provided at the end of the transition top plate 13. In some possible implementation schemes, a full-length plug-in profile 1321 is provided on the side of the horizontal plate 132 away from the vertical plate 131. The full-length plug-in profile 1321 has a slot 12113, and the low-zone top plate 12 is plugged into the slot 12113 of the full-length plug-in profile 1321. The full-length plug-in profile 1321 has the same or similar structure as the plug-in beam 1211 on the middle top plate 121 mentioned above. The structure of the full-length plug-in profile 1321 is as follows: Fig. 9 As shown, the plug-in installation of the low-zone top plate 12 to the transition top plate 13 structure is met, and the plug-in profile innovatively adds a full-length protrusion on the cross-section, which can ensure that the top plate assembly is smoothly plugged in during the installation process and plays the role of top screw tightening after installation.

[0110] The present application also provides a car body 100, comprising: a car body and a roof panel assembly in the above embodiment, wherein the roof panel assembly is located inside the car body and connected to the car body.

[0111] The carriage 100 includes a main air duct, and the carriage body includes two side walls 9 and a roof b connecting the two side walls 9. A cavity is formed between the top panel assembly and the roof b. The main air duct is arranged in the cavity, and the integrated air duct 1222 is connected to the main air duct.

[0112] The roof panel assembly of the present application realizes the transition from the high area to the low area of ​​the roof panel of the car 100, meeting the aesthetic requirements of the passenger compartment area and the visual flexibility of the passengers. The embodiment of the present application arranges an integrated air duct 1222 on the low-area roof panel 12, which is conducive to overall supply and solves the problem that the air-conditioning duct is difficult to install in the case of a special low-top vehicle body, thereby improving the installation processability, reducing costs, and improving installation efficiency.

[0113] In some possible implementations, the carriage 100 includes a duct joist c, which is disposed in a cavity and connected to the carriage body. The main air duct is supported on the duct joist c, and the high area top plate 11 and the transition top plate 13 are both connected to the duct joist c.

[0114] The embodiment of the present application also provides a vehicle, including the above-mentioned carriage 100.

[0115] Embodiment 2

[0116] Further, see Figures 10 to 16As shown, the embodiment of the present application also provides a detachable inspection door assembly 17 on the top plate assembly, which includes: an inspection door body 171 and a hinge 172. A detachable fixing matching portion is provided on one side of the inspection door body 171, and the hinge 172 includes a folding hook 1721 and a folding body 1722. The folding hook 1721 has a folding installation portion 17211 and a hook portion 17212. The folding installation portion 17211 is used for connection and fixing, and the hook portion 17212 is connected to the folding installation portion 17211. The folding body 1722 is connected to the side of the inspection door body 171 away from the detachable fixing matching portion. The folding body 1722 has a rotating shaft 17224, and the rotating shaft 17224 is rotatably supported on the hook portion 17212. Under the action of external force, the inspection door body 171 can move relative to the hook portion 17212, so that the rotating shaft 17224 of the folding body 1722 is separated from the hook portion 17212.

[0117] The hinge 172 of the present application consists of two parts: a folding hook 1721 and a folding body 1722. The rotating shaft 17224 on the folding body 1722 can be directly hung on the hook portion 17212 of the folding hook 1721, and the folding body 1722 can be fixed to the inspection door body 171 by a fastener 173. The folding installation portion 17211 of the folding hook 1721 can be fixed to the frame 16 of the carriage 100 by the fastener 173, so that the inspection door body 5 with the folding body installed is supported on the frame 16. After one side of the inspection door body is installed, the other side of the inspection door can be detachably connected to the corresponding frame 16 by a detachable fixing mating portion. The cleverness of this design lies in that when the mechanism components corresponding to the upper space of the inspection door body 171 need to be inspected, the detachable fixed matching part is opened and the inspection door body 171 can be folded downward to open. When necessary, the inspection door body 171 is pushed upward, so that the inspection door body 171 with the integrated folding body 1722 can be directly removed from the folding hook 1721, thereby expanding the inspection space.

[0118] The inspection door assembly of the present application can not only meet the normal opening and closing requirements, but also can inspect the components in the upper space corresponding to the projection of the inspection door, such as air-conditioning ducts, ceiling lights, water pipes, etc.; and can also, in special circumstances, without affecting other structures, disassemble the inspection door body 171 as a whole to further inspect adjacent components such as sliding door mechanisms.

The arc-shaped body 17212a is in an arc shape, and the shaft 17224 can be supported on the arc-shaped body 17212a and smoothly rotate around the arc-shaped body 17212a. When the folding hook 1721 is in the installed state, the retaining edge 17212b extends in the vertical direction, and the retaining edge 17212b plays the role of limiting the shaft 17224 to prevent the shaft 17224 from falling off.

[0120] In some possible implementations, the hinge hook 1721 includes a connecting portion 17212c, which extends along the thickness direction of the hinge mounting portion 17211, one side of the connecting portion 17212c is connected to the hinge mounting portion 17211, and the other side of the connecting portion 17212c is connected to the side of the arc body 17212a away from the retaining edge 17212b. The connecting portion 17212c protrudes upward, and the connecting portion 17212c and the retaining edge 17212b are respectively limited to the two sides of the rotating shaft 17224, which can support the rotating shaft 17224 to rotate at a high speed and prevent the rotating shaft 17224 from falling off.
