In some embodiments, the second port 5502 of the air guide channel 5510 can be located on the side of the peripheral wall 102 of the box body 10 close to the backrest of the vehicle seat (may also be referred to as the rear side of the box assembly 100), and the rear side of the box assembly 100 is provided with a plug-in connector (more specifically, an ISOFIX plug-in connector) 41 for connecting with the ISOFIX socket of the vehicle seat. When the carrier is installed on the vehicle seat, the air conditioner facing the rear seat of the vehicle blows air into the accommodation space 11 from the front side of the box assembly 100, and the second port 5502 blows air from the rear to the front, which can better dissipate heat from the accommodation space 11 and thus improve the ride comfort of the pet. Referring to FIG. 24, FIG. 27 to FIG. 29, the air guide shell 551 defines a meandering air guide channel 5510. The second port 5502 of the air guide channel 5510 blows air from the inside of the peripheral wall 102 of the box body 10 into the accommodation space 11. In some embodiments, the inner side wall 10212 of the peripheral wall 102 of the box body 10 is provided with an opening portion 1024, for example but not limited to between the two second supports 22. The opening portion 1024 is opposite to the second port 5502 to allow the air discharged from the second port 5502 to enter the inside of the accommodation space 11. In some embodiments, the second port 5502 does not protrude into the inside of the accommodation space 11 relative to the opening portion 1024. A seat cloth (inner seat cloth) not shown can cover the opening portion 1024, and the seat cloth (inner seat cloth) allows the air discharged from the second port 5502 to pass through it and enter the accommodation space 11. In some embodiments, the seat cloth (inner seat cloth) can also not cover the opening portion 1024, and in this case, a protective mesh can be provided at the opening portion 1024 or the second port 5502, which can prevent foreign matter from entering the inside of the air guide channel 5510 through the second port 5502. In some embodiments, the protective mesh can be a filter mesh, which can filter the air entering the inside of the accommodation space 11. Referring to FIG. 28 to FIG. 31, the fan shell 519 can be fixed to the base body 43 by fasteners 591. The air guide shell 551 can be fixed to the base body 43 by fasteners 592.

Referring to FIG. 30 and FIG. 31, in some embodiments, the air guide shell 551 can include at least two shell parts, each of which can be made by injection molding and then assembled into the air guide shell 551 to form a complete air guide channel 5510.In this embodiment, the air guide shell 551 comprises a first shell part 5511 and a second shell part 5512. The first port 5501 and the second port 5502 are both formed on the first shell part 5511. The first shell part 5511 is further formed with a bottom opening 55110, and the second shell part 5512 covers the bottom opening 55110. In this embodiment, the fastener 592 fixes the first shell part 5511 and the second shell part 5512 together on the base body 43, such that the second shell part 5512 is clamped between the first shell part 5511 and the base body 43. In some embodiments, a sealing gasket can be clamped between the first shell part 5511 and the second shell part 5512. The air guide shell 551 is assembled by multiple shell parts, which are easy to be molded, facilitating the production and processing of the air guide shell 551. In some embodiments, the inner wall of the base body 43 can be provided with a filter screen at the positions corresponding to the ventilation holes 432, to filter the dust. Of course, in some embodiments, a filter screen 51911 can also be provided at the air inlet 5191 and / or the air outlet 5192 of the fan shell 519. In addition, in some embodiments, a filter screen can be provided at any suitable position. The filter screen can be a filter mesh or a filter cotton, which can have a single-layer filter structure or a multi-layer filter structure, to ensure that the air discharged into the accommodation space 11 by the second port 5502 is clean and hygienic. In the case of a battery part, the battery part can be installed at any suitable position. For example, the battery part can be installed on the fan shell 519 or the base body 43. Referring to FIGS. 28 and 29, the control part 52 is located outside the fan shell 519, and more specifically, the control part 52 is fixed on the base body 43. In some embodiments, the inner part of the base body 43 is provided with a clamping part 435, and the control part 52 is clamped with the clamping part 435. In some embodiments, the clamping part 435 comprises two oppositely arranged L-shaped plates 4351, each of which extends from the inner wall of the base body 43, and the two L-shaped plates 4351 form a clamping groove for clamping the control part 52. In some embodiments, a reinforcing rib plate 4352 is arranged between each L-shaped plate 4351 and the base body 43. Referring to FIGS. 33 and 34, in some embodiments, the control part 52 comprises a fixed outer cover 527, a fixed inner cover 526, and a PCB circuit board 52E. When the control part 52 is clamped with the clamping part 435, the fixed outer cover 527 abuts against the inner wall of the base body 43. The fixed outer cover 527 can be provided with control buttons 522.The control button 522 can include a switch button, and can also include a wind speed button. In this embodiment, the fixed outer cover 527 is provided with a mounting hole 5270, a sleeve 5274 is sleeved in the mounting hole 5270, and the control button 522 is sleeved in the sleeve 5274. In this embodiment, the control button 522 is a mechanical button, and a through hole 4313 is arranged on the base body 43, and the control button 522 is exposed through the through hole 4313. When the control button 522 is pressed by an external pressing force, the control button 522 can be pressed down by sliding along the sleeve 5274. The control part 52 can also include a reset spring 529, which can push the control button 522 to reset when the external pressing force is released. In addition, an axial limiting structure (not shown in the figure) for preventing the control button 522 from falling off from the sleeve 5274 can be arranged between the control button 522 and the sleeve 5274, which can be, for example, a hole shoulder and a shaft shoulder matched with each other or other suitable structures.

[0004] The PCB 521 can be positioned on the fixed inner cover 526 and clamped between the fixed inner cover 526 and the fixed outer cover 527. The PCB 521 is provided with a touch switch 5212. In some embodiments, when the control button 522 is a switch button and the control button 522 is pressed, the touch switch 5212 is triggered to act, i.e., the external power supply or the battery part starts to supply power to the motor of the fan part 51 or stops supplying power to the motor of the fan part 51. In some embodiments, the reset spring 529 can be located in the sleeve 5274 and clamped between the control button 522 and the PCB 521. The fixed inner cover 526 can be formed with a clamping groove 5265 for accommodating the PCB 521. In some embodiments, a clamping structure 528 can be provided between the fixed outer cover 527 and the fixed inner cover 526 to allow the fixed outer cover 527 and the fixed inner cover 526 to be reliably engaged together, thereby stably clamping the PCB 521 therebetween. The clamping structure 528, for example, includes a clamping arm 5281 extending from one of the fixed outer cover 527 and the fixed inner cover 526, and a clamping recess 5282 located in the other one of the fixed outer cover 527 and the fixed inner cover 526, the clamping arm 5281 and the clamping recess 5282 being clamped. In some embodiments, to ensure that the control part 52 is stably fixed to the base body 43, the wall of the clamping groove 5265 can be fixed to the third positioning point 4303 inside the base body 43 by a fastener 5266. The control part 52 can further include a charging port 523 electrically connected to the PCB 521, through which the external power supply can supply power to the motor 511. More specifically, the external power supply supplies power to the motor 511 through the charging port 523, the PCB 521, and the wire harness 5112 (see FIG. 30) of the motor of the fan part 51. The fixed inner cover 526 can have a through hole 5263 through which the wire harness 5112 is electrically connected to the PCB 521. In embodiments provided with a rechargeable battery part, the external power supply can charge the battery part through the charging port 523. In the present embodiment, the charging port 523 is arranged at a suitable position on the PCB 521. The fixed outer cover 527 is provided with a through hole 5271, and the base body 43 is provided with a through hole 4315, and the charging port 523 is arranged in the through hole 5271 and the through hole 4315.In some embodiments, the air deflector housing 551 in the carrier 1000 shown in the foregoing Figs. 24-34 can be appropriately deformed to provide an air direction guiding structure near the second port 5502 of the air deflector housing 551 for guiding the air discharged from the second port 5502 to blow from the second port 5502 and its opposite opening portion 1024 to the accommodation space 11 in a desired direction. Such embodiments will be described below with reference to Figs. 35-42. It can be understood that in these embodiments, except that the air deflector housing 551 is different from the foregoing, the remaining components in the carrier 1000 can be referred to the relevant description of the foregoing Figs. 24-34. Fig. 35 schematically shows a perspective view of another example carrier 1000 according to a fourth embodiment of the present application. Fig. 36 shows a side view of the carrier 1000 shown in Fig. 35. Figs. 37-40 respectively show perspective views of the air deflector housing 551 in the carrier 1000 shown in Fig. 35 from different viewing angles, in which the second housing portion is omitted. Figs. 41-42 respectively show perspective views of another example air deflector housing 551 from different viewing angles, in which the second housing portion is omitted. Referring to Figs. 37-42, and also applicable to Figs. 28-31 and later-described Figs. 43-55, the air deflector housing 551 is generally L-shaped and includes a first air deflector segment 5513 and a second air deflector segment 5514 that are in communication with each other. The first air deflector segment 5513 extends generally in a horizontal direction (e.g., transverse direction D2), and the second air deflector segment 5514 extends generally in a vertical direction (height direction D3). The second air deflector segment 5514 can have an included angle with the first air deflector segment 5513, which is an obtuse angle in Figs. 37-40, but can also be a right angle or an acute angle. The first port 5501 is formed at one end of the first air deflector segment 5513, the other end of the first air deflector segment 5513 is connected to the bottom end of the second air deflector segment 5514, and the second port 5502 is formed at one side of the top end of the second air deflector segment 5514. Referring to Figs. 37-42, and also applicable to Figs. 28-31 and later-described Figs. 43-55, the air deflector housing 551 can be fixed to the base body 43 by fasteners 592. Wherein, the two sides of the first air deflector segment 5513 can be provided with one or more fastener mounting portions 5516, each fastener mounting portion 5516 can include a horizontally extending mounting bottom plate 55161 and two vertically upwardly extending mounting side plates 55162 connected to the two sides of the mounting bottom plate 55161. The mounting bottom plate 55161 can be provided with mounting holes 551610 for mounting the aforementioned fasteners 592.Unlike the air guide housing 551 shown in FIGS. 24-34, in some embodiments, referring to FIGS. 37 and 38, and also applicable to FIGS. 43-55 described later, the mounting portion 5516 can further include a reinforcing rib 55163 connected between each mounting side plate 55162 and the side wall of the first air guide section 5513 adjacent to the mounting side plate 55162. The reinforcing rib 55163 can be located on the other opposite side of the mounting side plate 55162 where the mounting bottom plate 55161 is located. The two reinforcing ribs 55163 can be located outside the two mounting side plates 55162, with the mounting bottom plate 55161 located between the two mounting side plates 55162. It can be understood that only the first housing portion 551L is shown in FIGS. 37-42 and the second housing portion is omitted. However, the air guide housing 551 shown in FIGS. 37-42 can also include the second housing portion, the features of which can be referred to the description of the second housing portion 5512 shown in FIGS. 30 and 31 described previously. With continued reference to FIGS. 37-42, and also applicable to FIGS. 28-31 described previously, the second air guide section 5514 can include two air guide side plates 55141 spaced apart in the longitudinal direction D1, an air guide front plate 55142 connected between the two air guide side plates 55141 and close to the first air guide section 5513, and an air guide back plate 55143 connected between the two air guide side plates 55141 and away from the first air guide section 5513, the two air guide side plates 55141, the air guide front plate 55142, and the air guide back plate 55143 collectively enclosing an air guide passage 5510 therethrough. The second port 5502 can be formed at the top end of the air guide front plate 55142. The second air guide section 5514 can further include an air guide top plate 55145 connected to the top end of the air guide back plate 55143, with the air guide back plate 55143 abutting the air guide top plate 55145 and located on the side of the air guide top plate 55145 away from the second port 5502. The air guide top plate 55145 extends generally in the horizontal direction forward from the top end of the air guide back plate 55143. The air guide top plate 55145 is located at the upper edge of the second port 5502, with the front edge of the air guide top plate 55145 forming the upper edge of the second port 5502. By appropriately arranging the shapes and / or angles of the various plates in the second air guide section 5514, the air outlet angle of the air discharged from the second port 5502 can be adjusted.In some embodiments, unlike the air guide shell 551 shown in FIGS. 24-34, the air guide top plate 55145 includes a plurality of air guide sub-top plates 55145a arranged side by side in the horizontal direction (e.g., the longitudinal direction D1), and at least two of the plurality of air guide sub-top plates 55145a have different inclination angles relative to the horizontal plane. For example, referring to FIGS. 37-40, the air guide top plate 55145 can include two air guide sub-top plates 55145a arranged side by side in the longitudinal direction D1. Referring to FIG. 40, one of the air guide sub-top plates 55145a has an acute inclination angle al relative to the horizontal plane, and the other air guide sub-top plate 55145a has an acute inclination angle a2 relative to the horizontal plane, and a2>al. In FIG. 40, for example, al is close to 0 degrees, and a2 is approximately 30 degrees. It can be understood that FIGS. 37-40 are exemplary and not limiting, and the number of air guide sub-top plates 55145a included in the air guide top plate 55145, the number of different inclination angles between the air guide sub-top plates 55145a, and the specific values of the inclination angles, can be changed as needed. For example, more than three air guide sub-top plates 55145a can have different inclination angles, or more than three air guide sub-top plates 55145a can have two inclination angles arranged alternately, where an odd number of air guide sub-top plates 55145a have one inclination angle, and an even number of air guide sub-top plates 55145a have another inclination angle, etc. The present application is not limited in this regard. By providing at least two air guide sub-top plates 55145a with different angles at the upper edge of the second port 5502, the air blown out of the second port 5502 and the opening portion 1024 can be blown in multiple angles or directions to the accommodation space 11, and have a larger air outlet angle in the height direction D3, thereby improving the air blowing area and the heat dissipation, ventilation effect. In some embodiments, referring to FIGS. 37-42, the air guide back plate 55143 can include a plurality of air guide sub-back plates 55143a arranged side by side in the height direction D3, and the plurality of air guide sub-back plates 55143a have different inclination angles relative to the horizontal plane, for example, the inclination angles of the plurality of air guide sub-back plates 55143a gradually decrease from bottom to top, so that from the bottom end of the air guide back plate 55143 to the top end of the air guide back plate 55143, the plurality of air guide sub-back plates 55143a gradually tilt toward the side of the second port 5502.For example, referring to FIGS. 40 and 41, the air guide back plate 55143 can include three air guide sub-back plates 55143a arranged side by side in the height direction D3, where the air guide sub-back plate 55143a at the bottom end has an obtuse angle a3 with respect to the horizontal plane, the air guide sub-back plate 55143a at the middle has an angle a4 that is approximately a right angle with respect to the horizontal plane, and the air guide sub-back plate 55143a at the top end has an acute angle a5 with respect to the horizontal plane, i.e., a3>a4>a5. The adjacent air guide sub-back plates 55143a can have a smooth transition therebetween. It can be understood that the number of air guide sub-back plates 55143a included in the air guide top plate 55145 and the specific values of the angles can be changed as needed, and FIGS. 37-42 are merely exemplary and not limiting. For example, there can be only two or more than three air guide sub-back plates 55143a, which is not limited by the present application. By gradually tilting the plurality of air guide sub-back plates 55143a from the bottom end to the top end toward the second port 5502 side, the air in the air guide housing 551 can be further guided to flow more smoothly out of the second port 5502 and the opening portion 1024. Furthermore, because the angle of the air guide sub-back plate 55143a at the top end that interfaces with the air guide top plate 55145 is an acute angle, rather than approximately a right angle as in FIGS. 30 and 31, the air guide sub-back plate 55143a at the top end can transition more smoothly with the air guide top plate 55145, thereby facilitating the guidance of the air flow direction by the air guide top plate 55145. In some embodiments, referring to FIGS. 41-42, the air guide housing 551 can further include one or more air guide ribs 5517 arranged side by side in the horizontal direction, which can be located on the inner wall of the air guide top plate 55145 and / or the air guide back plate 55143. Each of the one or more air guide ribs 5517 can extend substantially in the direction from the first port 5501 to the second port 5502. In embodiments including a plurality of air guide ribs 5517, the plurality of air guide ribs 5517 can have the same or different angles with respect to the side edges of the air guide top plate 55145 and / or the air guide back plate 55143. The plurality of air guide ribs 5517 can gradually change from converging to diverging in the direction from the first port 5501 toward the second port 5502. The spacing between adjacent two of the plurality of air guide ribs 5517 gradually increases from the end away from the second port 5502 to the end close to the second port 5502.The first distance between two adjacent wind guide ribs 5517 near the second port 5502 is greater than the second distance between two adjacent wind guide ribs 5517 away from the second port 5502. For example, referring to FIG. 42, the wind guide shell 551 can include two wind guide ribs 5517 on the wind guide top plate 55145 and the wind guide back plate 55143. The distance between the two wind guide ribs 5517 gradually increases from the end away from the second port 5502 to the end near the second port 5502, and the two wind guide ribs 5517 have a first distance dl near the second port 5502 and a second distance d2 away from the second port 5502, dl > d2. It can be understood that FIG. 42 is exemplary and not limiting, and the number of wind guide ribs 5517 in the wind guide shell 551, and the specific values of the inclination angle of each wind guide rib 5517 and the specific values of the distance between adjacent wind guide ribs 5517, can be changed as needed, for example, there can be more than three wind guide ribs 5517. Although the wind guide ribs 5517 are shown in FIG. 42 as extending from the wind guide back plate 55143 to the wind guide top plate 55145, the wind guide ribs 5517 can only extend on the wind guide top plate 55145 or only on the wind guide back plate 55143, which is not limited by the present application. By gradually changing the multiple wind guide ribs 5517 from converging to each other to diverging to each other in the direction towards the second port 5502, the air blown out of the second port 5502 and the opening 1024 can have a larger air outlet angle in the longitudinal direction D1, thereby improving the blowing area and heat dissipation, ventilation effect. It can be understood that the configuration of the multiple wind guide sub-top plates 55145a with different inclination angles shown in FIGS. 37-40 can be combined with the configuration of one or more wind guide ribs 5517 shown in FIGS. 41-42. The wind guide top plate 55145 of the wind guide shell 551 can include the multiple wind guide sub-top plates 55145a with different inclination angles described above, and one or more wind guide ribs 5517 can be provided on the inner wall of the wind guide top plate 55145 and / or the wind guide back plate 55143. As described above, the fan assembly 500 can include a control panel 525, and the control panel 525 is provided with control buttons 522 and a charging port 523. The control panel 525 is arranged on the side of the box assembly 100, and the control panel 525 is configured to control the opening and closing of the fan part 51. In some related technologies, the control panel 525 is generally arranged centrally on the side of the box assembly 100 on which the long side 1021 is located.However, in this center arrangement, when the carrier 1000 is mounted on the trolley via the engagement rod 42, the components on some trolleys can block the area where the control panel 525 is located, causing inconvenience for the user to operate the control panel 525. In some embodiments, referring to FIGS. 35 and 36, and applicable to FIGS. 43 and 44 described below, viewed from the side of the carrier 1000 where the control panel 525 is provided, the first center line CI of the control panel 525 in the height direction D3 is offset to the third distance d3 from the second center line C2 of the base 40 or the cabinet body 10 in the height direction D3. For example, but not limited to, the first center line CI of the control panel 525 can be located at one-third of the side of the carrier 1000 or more, at one-fourth of the side of the carrier 1000 or more, and so on. In FIGS. 35 and 36, FIGS. 43 and 44, the control panel 525 is located on the base 40, however, the control panel 525 can also be located on the cabinet body 10 (for example, FIG. 14) or the bracket assembly 20. In this way, by offsetting the control panel 525 to the side of the carrier 1000 in the longitudinal direction D1 by a certain distance, the control panel 525 can be avoided from being blocked by the components on some trolleys, thereby facilitating the user's operation. In some embodiments, the carrier 1000 shown in the foregoing FIGS. 24 to 34 can be appropriately deformed to further include an air outlet panel 107, which can serve as a wind direction guiding structure for guiding the air discharged from the second port 5502 to blow from the second port 5502 and its opposite opening portion 1024 to the accommodation space 11 in a desired direction. In addition, the air guide shell 551 and the opening portion 1024 can also be adaptively deformed. Such embodiments will be described below with reference to FIGS. 43 to 55. It can be understood that in these embodiments, except that the air outlet panel 107 and the air guide shell 551 and the opening portion 1024 related thereto are different from the foregoing, the remaining components in the carrier 1000 can refer to the related description of the foregoing FIGS. 24 to 34. FIGS. 43 and 44 schematically show perspective views of different views of another example carrier 1000 according to a fourth embodiment of the present application, in which the ceiling assembly 300 is omitted. FIG. 45 shows a U4-U4 cross-sectional view of the carrier 1000 shown in FIG. 44. FIG. 46 shows a U5-U5 cross-sectional view of the carrier 1000 shown in FIG. 44. FIGS. 47 and 48 show perspective views of different views of the fan portion 51, the air guide portion 55, and the air outlet panel 107 in the carrier 1000 shown in FIG. 43.FIG. 49 shows a side view of the carrier 1000 shown in FIG. 43. FIG. 50 shows a U6-U6 cross-sectional view of the carrier 1000 shown in FIG. 44. FIGS. 51 and 52 show perspective views of different viewing angles of the air outlet panel 107 in the carrier 1000 shown in FIG. 43 being fixed to the seat cloth 13. FIGS. 53-55 show the carrier 1000 shown in FIG. 43 being wrapped with the seat cloth 13 in different configurations, respectively. Referring to FIGS. 43-55, in the present embodiment, the carrier 1000 further includes the air outlet panel 107, which can have the air outlet structure 1071 formed thereon - see FIG. 52, the air outlet structure 1071 can be formed in the air outlet region 107a of the air outlet panel 107. The outer boundary 1070a of the air outlet region 107a is indicated by the dashed line in FIG. 52. The air outlet region 107a can generally have the same shape as the second port 5502. Referring to FIGS. 51 and 52, the air outlet panel 107 can further include the binding region 107b at least partially surrounding the air outlet region 107a. The binding region 107b between the outer boundary 1070a of the air outlet region 107a and the outer boundary 1070b of the air outlet panel 107 is exemplarily shown in FIG. 52. Wherein, the outer boundary 1070b of the air outlet panel 107 is the outer boundary of the binding region 107b, and the outer boundary 1070a of the air outlet region 107a is the inner boundary of the binding region 107b. The binding region 107b can not have the air outlet structure 1071 - the binding region 107b can enhance the strength of the air outlet panel 107 as a whole. Furthermore, as will be discussed below, the binding region 107b can be used to fix the air outlet panel 107 to predetermined components in the carrier 1000. Referring to FIGS. 53 and 54, the air outlet panel 107 can be mounted to and detached from the inner side wall of the peripheral wall 102 of the cabinet body 10. Referring to FIG. 54, the peripheral wall 102 of the cabinet body 10 is provided with the opening portion 1024, which exposes the second port 5502 toward the accommodation space 11.
